1.3	09-Apr-2005	dsl	KNF
1.2	14-Jun-2000	cgd	fix up NetBSD RCS Ids to match the standard, and the leading comment as to match as well. No functional changes.
1.1	26-Sep-1998	christos	branches: 1.1.8; Adapt to new signal changes (from Jason)
1.1.8.1	23-Jun-2000	minoura	Sync w/ netbsd-1-5-base.
1.3	01-Dec-2024	rillig	libc: modernize lint stubs Use prototype function definitions instead of identifier lists, as C23 does not support the latter. Remove redundant /ARGSUSED/ comments and parentheses.

1.1	06-Nov-1997	cgd	branches: 1.1.2; 1.1.10; lint stubs for functions which ports use assembly versions. When using an assembly version of a function, add the right lint stub to the Makefile.inc which specifies the source to build the function (see the arch/i386/*/Makefile.inc). Can't just lint the normal C versions of these functions, because some of them don't _have_ normal C versions and if that were done dependencies would get messed up.
1.1.10.1	23-Jun-2000	minoura	Sync w/ netbsd-1-5-base.
1.1.2.2	08-Nov-1997	veego	pull up changes from the trunk (approved by perry) from cgd: >lint stubs for functions which ports use assembly versions.

1.3	27-Feb-2001	cgd	branches: 1.3.114; fix NetBSD RCS id tags
1.2	06-Jul-2000	christos	mark the prototype mismatch as linted. We cannot do better because of the widening ansi rules.
1.1	15-Jan-1999	bouyer	Move the bswap functions from libutil to libc (this bups the minor of libc and the major of libutil). For little-endian architectures merge the bnswap() assembly versions with nto* and hton* using symbols aliasing. Use symbol renaming for the bswap function in this case to avoid namespace pollution. Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian machines, common code for inline macros go in machine/byte_swap.h Sync libkern with libc. Adjust #include in kernel sources for machine/bswap.h.

1.216	31-May-2022	riastradh	branches: 1.216.2; libc: Reintroduce getentropy. This was introduced two years ago when the getrandom/getentropy API question was still open, and removed because the discussion was ongoing. Now getentropy is more widely adopted and soon to be in POSIX. So reintroduce the symbol into libc since we'll be keeping it anyway. Discussion of details of the semantics, as interpreted by NetBSD, is ongoing, but the symbol needs to get in before the netbsd-10 branch. The draft POSIX text is (https://www.opengroup.org/austin/docs/austin_1110.pdf): SYNOPSIS #include <unistd.h> int getentropy(void *buffer, size_t length); DESCRIPTION The getentropy() function shall write length bytes of data starting at the location pointed to by buffer. The output shall be unpredictable high quality random data, generated by a cryptographically secure pseudo-random number generator. The maximum permitted value for the length argument is given by the {GETENTROPY_MAX} symbolic constant defined in <limits.h>. RETURN VALUES Upon successful completion, getentropy() shall return 0; otherwise, -1 shall be retunred and errno set to indicate the error. ERRORS The getentropy() function shall fail if: [EINVAL] The value of length is greater than {GETENTROPY_MAX}. The getentropy() function may fail if: [ENOSYS] The system does not provide the necessary source of entropy. RATIONALE The getentropy() function is not a cancellation point. Minor changes from the previous introduction of getentropy into libc: - Return EINVAL, not EIO, on buflen > 256. - Define GETENTROPY_MAX in limits.h. The declaration of getentropy in unistd.h and definition of GETENTROPY_MAX in limits.h are currently conditional on _NETBSD_SOURCE. When the next revision of POSIX is finalized, we can expose them also under _POSIX_C_SOURCE > 20yymmL as usual -- and this can be done as a pullup without breaking existing compiled programs.

1.202	06-May-2020	nia	Add getentropy() to libc - a simple wrapper to access the kernel CSPRNG. Posted to tech-userlevel@ a week ago and reviewed by riastradh@. GETENTROPY(3) Library Functions Manual GETENTROPY(3) NAME getentropy - fill a buffer with high quality random data LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <unistd.h> int getentropy(void *buf, size_t buflen); DESCRIPTION The getentropy() function fills a buffer with high quality random data, suitable for seeding cryptographically secure psuedorandom number generators. getentropy() is only intended for seeding random number generators and is not intended for use by regular code which simply needs secure random data. For this purpose, please use arc4random(3). The maximum value for buflen is 256 bytes. IMPLEMENTATION NOTES getentropy() reads from the sysctl(7) variable kern.arandom. RETURN VALUES The getentropy() function returns 0 on success, and -1 if an error occurred. ERRORS getentropy() will succeed unless: [EFAULT] The buf argument points to an invalid memory address. [EIO] Too many bytes were requested. SEE ALSO arc4random(3), rnd(4) STANDARDS The getentropy() function is non-standard. HISTORY The getentropy() function first appeared in OpenBSD 5.6, then in FreeBSD 12.0, and NetBSD 10.

1.199	09-May-2017	kre	Add the new signalname/signalnext/signalnumber interface to libc. This as discussed on current-users in the thread entitled: Proposal: new libc/libutil functions to map SIGXXXX <-> "XXXX" that can be found (starting at): http://mail-index.netbsd.org/current-users/2017/04/28/msg031600.html These functions provide the mechanism to enable applications to divorce themselves from internal details of the signal implementation. Libc minor bumped, prototypes in <signal.h>, sets lists updated (and sorted). One and all: feel free to improve the sources & man page (etc), but please do not change the function signatures without discussion.
1.198	07-Feb-2017	kamil	branches: 1.198.2; Mark exect(3) obsolete and bind it to plain execve(2) on all platforms The original exect(2) from BSD4.2 was enabling bit for tracing (single-step mode) and calling execve(2). The purpose of it was to generate a signal for a tracer once the application will change its image to a new program. This approach no longer works as: - exect(2) traces (single-steps) libc and it requires hundreds or thousands steps before entering a new image - it's vax and x86 specific code - this functionality has been moved to the kernel - once a process is traced it will generate SIGTRAP with si_code TRAP_EXEC and route it to its debugger - the side effects and unportability make this interface unusable - there are no known users of this interface - it apparently never worked better since day0 of NetBSD ("day0 bug") Users are requested to move to other execve(2) variants. Calling current execve(2) as it is the most similar behavior to this one from BSD4.2. Discussed several times on mailing lists and in PR/51700. Add warning to exect(3) telling about marking this function obsolete. This function is prepared to be removed in next libc major bump. Sponsored by <The NetBSD Foundation>
1.197	12-Jan-2017	christos	branches: 1.197.2; Split syslog.c to: - syslog_ss.c _ss api functions (don't use stdio, time) - syslog.c: syslog* non _ss api functions (use stdio, time) - xsyslog.c> common guts. The motivation for this is not to drag in stdio/locale/floating point/time for every binary, since syslog_ss() is used in __stack_check_fail() for SSP.
1.196	04-Oct-2016	kamil	Add timespec_get(3) in <time.h> and enable unconditionally struct timespec These changes conforms to the C11 standard References: - 7.27.1/3 Components of time (struct timespec) - 7.27.2.5 The timespec_get function According to ISO/IEC 9899:201x (draft) <time.h> defines the timespec structure and declares the timespec_get(3) function with TIME_UTC definition. According to a C++17 standard draft <ctime> offers the same interface in the std:: namespace. The timespec_get function modifies the timespec object pointed by ts to hold the current calendar time in the given base. The standard notes only the TIME_UTC base with implementation defined value, set it to 1 as zero is reserved for error handling. Once operation was successful this function returns passed base, otherwise exits with zero. The timespec struct was already part of the POSIX standard in <time.h>. Enable this interface unconditionally in the header to allow to use it in a code prior C11 and C++17 as an extension. Review notes from <christos>

1.121	28-May-2003	christos	add mutex locking for directories and readdir_r(3). Influenced by FreeBSD.
1.120	13-Feb-2003	nathanw	Add pthread_atfork() man page.
1.119	13-Feb-2003	nathanw	Implement pthread_atfork() (in libc, because the required threadlib stub behavior is exactly the same as the usual behavior).
1.118	21-Jan-2003	wiz	Add makecontext(3) from Klaus Klein.
1.117	18-Jan-2003	thorpej	Merge the nathanw_sa branch.
1.116	15-Jan-2003	kleink	Add sighold(3), sigignore(3), sigrelse(3) and sigset(3) to libc. Fixes PR lib/19212, now redesignated standards/19212, from David Laight.
1.115	27-Sep-2002	wiz	Add documentation for utmpx and some related functions. Thanks for some explanations to christos, and for some STANDARDS hints to Klaus Klein.
1.114	22-Aug-2002	abs	Move humanize_number(3) from libutil to libc as per discussion on tech-misc Revert minor number bump on libutil (with note to skip it next update), and bump libc.
1.113	27-Jul-2002	christos	Add utmp processing functions
1.112	30-Jun-2002	bjh21	Version times() so that programs compiled before the recent change to make sysconf(_SC_CLK_TCK) return hz will work. In detail: __times13() returns values scaled by hz. times() returns values scaled by 100. <sys/times.h> renames times() to __times13(). _SC_CLK_TCK has changed from 3 to 39. sysconf(3) returns 100. sysconf(39) returns hz. CLK_TCK is defined as sysconf(39).
1.111	24-May-2002	itojun	add arc4random(3). from openbsd
1.110	22-Feb-2002	christos	branches: 1.110.2; A simple utmpx implementation. Nothing uses it yet. TODO: write the lastlog*() stuff.
1.109	24-Jan-2002	lukem	- Implement pwcache_userdb(3), which changes the routines that user_from_uid(3) and uid_from_user(3) use to lookup user information. - Implement pwcache_groupdb(3), which changes the routines that group_from_gid(3) and gid_from_group(3) use to lookup group information. - Ensure that private functions in pwcache.c are declared static - Use strlcpy(3) instead of strncpy(3)
1.108	07-May-2001	kleink	Internally rename sysconf() to __sysconf() to make its latter name suitable for use from public headers. Also, do so on all platforms.
1.107	10-Mar-2001	cgd	Add shquote() and shquotev(). From the manual page: The shquote() and shquotev() functions copy strings and transform the copies by adding shell escape and quoting characters. They are used to encapsulate arguments to be included in command strings passed to the system() and popen() functions, so that the arguments will have the cor- rect values after being evaluated by the shell.
1.106	19-Feb-2001	cgd	branches: 1.106.2; add getprogname() and setprogname()
1.105	20-Oct-2000	briggs	Add {__,}fmtcheck(), a function specified by Bill Sommerfeld to check a user-supplied format string against a fallback format string to ensure that they will consume arguments of the same type. libc minor bump for new API entry point.
1.104	29-Aug-2000	wennmach	Added MLINKS for svis, strsvis, and strsvisx
1.103	03-Jan-2000	msaitoh	branches: 1.103.4; nlist for COFF
1.102	13-Sep-1999	kleink	Add an XSH5 ulimit()/<ulimit.h> implementation.
1.101	12-Sep-1999	kleink	Add an XSH5 fmtmsg() implementation.
1.100	12-Sep-1999	kleink	Move the function implementations of (the non-ANSI) isascii() and toascii() into separate modules to avoid namespace clashes.
1.99	01-May-1999	ross	Fix fpgetmask.3 MLINKS braino.
1.98	30-Apr-1999	ross	* New MI man page for fp{set,get}{round,sticky,mask}(3). * Implement fpgetsticky() for alpha. * Direct fpsetsticky() and fp{get,set}mask() into alpha kernel via sysarch(2). * Define new sysarch(2) stub for above and install and distribute sysarch.h for alpha. (The fpcr IS user mode r/w, but for reasons beyond the scope of a commit message kernel calls are needed.) And much kernel Magick is required before these do anything, but this way programs compiled under 1.4 will DTRT on future snapshots and releases.
1.97	24-Feb-1999	drochner	branches: 1.97.2; use ${ARCHDIR} instead of ${.CURDIR}/arch/${MACHINE_ARCH} where appropriate libc builds on pmax again
1.96	19-Jan-1999	abs	Add '-f disktab' option to disklabel, via lib/6623 from Greg A. Woods <woods@most.weird.com>. (Very) slightly tweaked disklabel.8
1.95	15-Jan-1999	bouyer	Move the bswap functions from libutil to libc (this bups the minor of libc and the major of libutil). For little-endian architectures merge the bnswap() assembly versions with nto* and hton* using symbols aliasing. Use symbol renaming for the bswap function in this case to avoid namespace pollution. Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian machines, common code for inline macros go in machine/byte_swap.h Sync libkern with libc. Adjust #include in kernel sources for machine/bswap.h.
1.94	30-Nov-1998	thorpej	Build __errlist14.c, __siglist14.c, and __signame14.c
1.93	26-Sep-1998	christos	Adapt to new signal changes (from Jason)
1.92	28-Jul-1998	mycroft	Add links for uid_from_user(3) and gid_from_group(3).
1.91	08-Jun-1998	lukem	* move pw_scan() from libutil to libc * add support for YP "master.passwd.by" (master.passwd in YP, including pw_passwd) and "passwd.adjunct.by" (SunOS `secure' maps (?)), based on code in FreeBSD and partially from OpenBSD. this is only used if euid == 0. with this, the YP "passwd.by" maps can have `' in the pw_passwd field. * use pw_scan() to parse YP "passwd.by" and "master.passwd.by" entries XXX: i didn't test the "passwd.adjunct" support...
1.90	28-Apr-1998	fair	make explicit why an MLINKS for setpwfile.3 is commented out
1.89	19-Mar-1998	fair	remove getsubopt.3 - there is another man page for this in ../stdlib that came from the Lite2 merge. This closes PR4600
1.88	02-Feb-1998	perry	add realpath.3, getsubopt.[c3]
1.87	02-Feb-1998	perry	it turns out we don't want getvfsbyname after all.
1.86	02-Feb-1998	perry	merge/update to lite-2
1.85	20-Dec-1997	kleink	Add lockf(), an alternate interface to perform advisory record locking; per XPG4.2.
1.84	14-Nov-1997	mrg	add missing .Nm entries. from spz@serpens.swb.de.
1.83	03-Nov-1997	kleink	Forgot to add basename()/dirname() manpages in last commit.
1.82	02-Nov-1997	kleink	Add basename() and dirname(), from XPG4.2.
1.81	21-Oct-1997	fvdl	branches: 1.81.2; Hacks to enable libc to work without bumping the major.
1.80	20-Oct-1997	christos	Bring timezone back to libc.
1.79	16-Oct-1997	christos	timezone moved to libcompat
1.78	16-Jul-1997	mikel	add toascii(3)
1.77	24-Feb-1997	lukem	branches: 1.77.2; man page for stringlist functions
1.76	17-Jan-1997	lukem	Add stringlist implementation Convert getnetgrent from private stringlist to public version
1.75	07-Nov-1996	jtc	New __errno() function, returns the address of the errno variable.
1.74	16-Oct-1996	perry	branches: 1.74.2; Nuked tahoe machine specific conditionals.
1.73	27-Sep-1996	cgd	Seriously revamp libc's nlist()/__fdnlist() support: (1) split nlist() into multiple files, for clarity and to make ELF 32/64 support easier, (2) support multiple executable types at the same time, and (3) add support for 32- and 64-bit ELF (32-bit ELF support originally from OpenBSD, but with several bug fixes so that it actually handles symbols types more correctly (and therefore _works_ for some of the more tricky uses of the nlist routines) and changes for 64-bit ELF support).
1.72	03-Jul-1996	jtc	branches: 1.72.2; Split all exec*() functions out of exec.c into their own files.
1.71	15-Apr-1996	jtc	Split each function in err.c out into its own file. This is needed for systems without weak or indirect references.
1.70	25-Apr-1995	jtc	termios code has been moved to new libc/termios directory.
1.69	17-Apr-1995	ragge	Removed VAX specific definitions.
1.68	10-Mar-1995	jtc	Removed references to ctime.3 and tzset.3 manpages and associated manpage links (they have been moved to libc/time).
1.67	09-Mar-1995	jtc	date and time functions have been moved
1.66	25-Feb-1995	cgd	typo
1.65	25-Feb-1995	cgd	oops; biffed path
1.64	25-Feb-1995	cgd	update from Lite, clean up a bit, seperate arch-specific file list.
1.63	10-Feb-1995	cgd	branches: 1.63.2; list the files needed on the alpha.
1.62	11-Jan-1995	pk	Add sigsetjmp() for sparc.
1.61	23-Dec-1994	jtc	4.4lite's C language sigsetjmp() implementation is bogus, restore machine dependant versions.
1.60	22-Dec-1994	cgd	specify man pages the new way.
1.59	12-Dec-1994	jtc	Rework indirect reference support as outlined by my recent message to the tech-userlevel mailing list.
1.58	11-Dec-1994	christos	- Changed all internal libc references of {v,}err{x,} and {v,}warn{x,} to __{v,}err{x,} and __{v,}warn{x,} - moved err.c to __err.c and added err.c which contains weak references for the above functions. - Reordered the functions in __err.c to avoid redeclarations and changed the varargs declarations to conform with the K&R style.
1.57	10-Dec-1994	jtc	Use 44lite's clever sigsetjmp()/siglongjmp() implementation I just imported.
1.56	07-Dec-1994	deraadt	remove duplicate infinity.c
1.55	07-Dec-1994	phil	Adding sigsetjmp.S for ns32k.
1.54	14-Nov-1994	dean	Include files for pmax
1.53	20-Oct-1994	cgd	make the sysv functions real syscalls.
1.52	10-Oct-1994	jtc	Renamed sys_errlist[] and sys_nerr to __sys_errlist[] and __sys_nerr. The traditional API of sys_errlist[] and sys_nerr is provided by weak references if they are supported. Otherwise, we're forced to have to have two copies of the error message string table in the library. Fortunately, unless a program uses both sys_errlist[] and strerror(), only one of the copies will be linked into the executable. This is all to provide an clean namespace as required by ANSI. I've done the same for sys_siglist[], even though it is not required, to be consistant.
1.51	29-Aug-1994	mycroft	branches: 1.51.2; Fix broken import of Lite directory code.
1.50	19-Aug-1994	cgd	frexp.? is machine-dependent, as suggested by phil.
1.49	28-Jun-1994	jtc	branches: 1.49.2; install getnetgrent() manpage
1.48	26-Jun-1994	jtc	Ftok() routine, needed by most programs that use SysV IPC.
1.47	11-Jun-1994	jtc	Replace my version of confstr() with 4.4 lite's, which gets its values with sysctl().
1.46	28-May-1994	mycroft	We have shm again.
1.45	21-May-1994	chopps	no more lsearch.3.
1.44	19-May-1994	jtc	cuserid() was moved to libcompat w/4.4 lite.
1.43	19-May-1994	jtc	4.4lite's libcompat provided a lsearch() and lfind() implementation which has been already integrated into NetBSD, so we don't need/want mine anymore.
1.42	17-May-1994	mycroft	Add {set,get,end}netgrent().
1.41	11-May-1994	cgd	shm sources won't compile; no more shm.h
1.40	07-May-1994	cgd	update for present reality. shlib version number bump (last for a bit)
1.39	05-May-1994	cgd	add getgrouplist
1.38	14-Apr-1994	cgd	setproctitle(); no reason to have this code spread into N utils...
1.37	09-Apr-1994	mycroft	And strunvis(3), too.
1.36	09-Apr-1994	mycroft	Add links for strvis(3) and strvisx(3).
1.35	06-Apr-1994	cgd	M-x shuffle-functions-and-documentation basically, move things around so documentation is in the correct place, and bump appropriate functions into the 'compat' section.
1.34	27-Jan-1994	cgd	add two man pages
1.33	27-Jan-1994	cgd	stuff moved into libc
1.32	12-Jan-1994	cgd	moved to libcompat, where they belong.
1.31	08-Dec-1993	pk	Added some Sparc sources.
1.30	05-Dec-1993	cgd	get pc532 moved into ns32k; that's is MACHINE_ARCH
1.29	04-Dec-1993	cgd	update for .S and MACHINE_ARCH
1.28	03-Dec-1993	jtc	Add common definition of errno back to the C library. One notable program uses its own crt0.c, so it can't pick it up from there.
1.27	02-Dec-1993	mycroft	Remove hack for errlst.o.
1.26	02-Dec-1993	mycroft	Get rid of dated MLINKS for regexp man pages. Reported by Mark_Weaver@brown.edu.
1.25	29-Nov-1993	jtc	install cuserid(3) manpage.
1.24	17-Nov-1993	jtc	If _CS_PATH is defined in <unistd.h>, the latest bash assumes that confstr() will be present as well. Here is a quick implementation based on my online copy of 1003.2 (D11.2). I'll confirm that nothing has been changed in the final standard and write up a manual page soon.
1.23	14-Nov-1993	cgd	Add the System V message queue and semaphore facilities. Implemented by Daniel Boulet <danny@BouletFermat.ab.ca>
1.22	11-Nov-1993	jtc	Enable Henry Spencer's POSIX.2 compatible regular expression routines. Disable his earlier V8-style routines.
1.21	22-Oct-1993	jtc	Add my lsearch & lfind implementations.
1.20	19-Oct-1993	jtc	Use i386 sigsetjmp()/siglongjmp() implementation. Install sigsetjmp()/siglongjmp() links to setjmp manpage. Note that sigsetjmp() and siglongjmp() are 1003.1 compliant.
1.19	11-Oct-1993	jtc	Moved cuserid() from getlogin.c to its own file, cuserid.c. getlogin() and cuserid() do very different things, getlogin() is POSIX, while cuserid() is not (it was removed in the 1990 revision).
1.18	07-Oct-1993	cgd	always create libcrypt, and link with it where necessary. this will make life with shared libraries happier. also, get dummy crypt out of libc.
1.17	07-Oct-1993	cgd	make an arch directory in libc, and move all machine dirs into it
1.16	04-Oct-1993	jtc	Install isblank() manpage. Fix title of isblank() manpage (was isspace(), the manpage I started with).
1.15	01-Oct-1993	jtc	Install fts manpage as fts_open, fts_read, fts_children, fts_set and fts_close too.
1.14	17-Sep-1993	phil	pc532 specifics.
1.13	25-Aug-1993	brezak	Add syscall stubs for SYSV Shared Memory.
1.12	23-Aug-1993	jtc	Moved toupper and tolower tables from ctype_.c to their own files --- I received complaints about using shorts in the table (but i need a range of -1..255), so now the tables will not be used unless either toupper() or tolower() (and soon, setlocale()) are used. This can save up to 514 bytes. In toupper_.c and tolower_.c make sure that our assumption of EOF == -1 holds. Fixed bug where _toupper_tab_ was initialized pointing to _C_tolower_tab.
1.11	13-Aug-1993	brezak	Machine independent version of insque/remque
1.10	06-Aug-1993	mycroft	Add sys_signame[].
1.9	01-Aug-1993	mycroft	Add RCS identifiers.
1.8	25-Jul-1993	glass	Finally deprecate the old timezone() interface in favor of an XSH5 timezone/daytime pair; as proposed by J.T. in September, 1996. Fixes PR standards/11807 by Nick Hudson.
1.7	09-Jul-1993	cgd	update for better FP routines, from AT&T & elsewhere
1.6	16-Jun-1993	jtc	Make assert macro ansi complient.
1.5	04-Jun-1993	proven	Removed bugs and memory leaks from the directory function.
1.4	18-May-1993	cgd	bring in getcap routines, supplied by CSRG, from 4.4...
1.3	30-Apr-1993	glass	new err stuff
1.2	22-Mar-1993	cgd	added support for using real crypt
1.1	21-Mar-1993	cgd	branches: 1.1.1; Initial revision

1.1.1.2	25-Feb-1995	cgd	from lite, with minor name rearrangement to fit.
1.1.1.1	21-Mar-1993	cgd	initial import of 386bsd-0.1 sources
1.49.2.1	19-Aug-1994	cgd	make frexp.c machine-dependent, as ns32k has frexp.S
1.51.2.2	29-Aug-1994	mycroft	Fix broken import of Lite directory code.

1.1 Fixes PR lib/39662, shortcomings in LC_{MONETARY,NUMERIC,TIME,MESSAGES} db format. ok'ed by core and releng. (thanks for agc@, snj@ and i'm sorry for long time patience). [libc] - localeio.[ch] and lc.[ch] in src/lib/libc/locale was replaced by new locale-db implementation using citrus_db backend, see src/lib/libc/citrus/citrus_lc_.[ch]. - add citrus_bcs_strtou?l.c. don't use strtou?l locale implementation internally, because they're locale-aware function. - add some stubs for multi-locale issue, see {current,global}_locale.c. - remove some obsolete file, setrunelocale.c, ___runetype_mb.c. - remove __savectype() from ctypeio.[ch]. [tools] - mklocale(1): add new option ``-t'' that generates new style LC_{MONETARY,NUMERIC,TIME,MESSAGES} locale-db format. - chrtbl(1): added ctypeio.[ch] for __savectype(). [locale-db] - added en_US.US-ASCII locale. - removed some shareable locale definition file: en_US.US-ASCII -> en_US.ISO8859-1, en_US.UTF-8 zh_CN.eucCN -> zh_CN.GB18030 and more...see src/share/locale//Makefile. - remove obsoleted locale sr_YU, added new locale sr_ME, sr_RS. - change locale name ja_JP.ISO2022-JP -> ja_JP.ISO-2022-JP* for X11's locale.alias file alignments. - fix regression test, wrong wcs?width(3), NAN/INF usage. i tested release-build following arch: i386, amd64, hpc{mips,arm,sh}, sparc64, vax. citrus_lc_.[ch] also can read old-plain-text style locale-db. so that backward compatibility is keeped, but lc.[ch] can't read new citrus_db'ed locale-db and localeio.c never check sanity, so forward compatibility is broken ;-< old mklocale(1) doesn't know -t option, so you have to rebuild toolchain.

Disable 'missing header declaration' and 'nested extern' warnings for now. acpivmgenid(4): New driver for virtual machine generation ID. Added to amd64/ALL and i386/ALL kernel configurations, and made available as a loadable module acpivmgenid.kmod on x86, for now. TBD: Add to all ACPI-supporting GENERIC kernels. PR kern/58632: getentropy(2) and arc4random(3) do not reseed on VM fork entropy(9): Factor out subroutines to reset and gather entropy. `Reset' means we keep the data in the pool, but assume it had zero entropy. `Gather' means we request samples from all on-demand sources and wait for the synchronous ones to complete. No functional change intended, other than to expose new symbols -- just preparation to expose these to acpivmgenid(4), so it can use these when the VM host notifies us that we, the guest, have been cloned. PR kern/58632: getentropy(2) and arc4random(3) do not reseed on VM fork acpivmgenid(4): Reset and gather entropy on VM clone notification. PR kern/58632: getentropy(2) and arc4random(3) do not reseed on VM fork arc4random(3): Reseed if system entropy epoch changes. This can happen, for example, if the system is a VM instance, and the VM is cloned. This incurs the cost of a system call on every arc4random call, which is unfortunate, but 1. we don't currently have a (machine-independent) mechanism for exposing a read-only page to userland shared by the kernel to enable a cheaper access path to the entropy epoch; and 2. the algorithm here -- a simple application of ChaCha -- is likely also a bottleneck and could be much cheaper by (a) using sys/crypto/chacha for machine-dependent vectorized ChaCha code, and (b) filling a buffer (somewhere between a cipher block and a page) in a batch at a time, instead of running ChaCha to generate only 32 bytes at a time. So although this might be a performance hit, the security benefit is worthwhile and we have a clear path to do better than reversing the performance hit later. PR kern/58632: getentropy(2) and arc4random(3) do not reseed on VM fork acpivmgenid(4): Nix BUGS that have been squashed. Reference kern.entropy.epoch for the remaining bug (which is a performance issue, not a security issue). PR kern/58632: getentropy(2) and arc4random(3) do not reseed on VM fork entropy(9): Allow unprivileged reads of sysctl kern.entropy.epoch. Applications need this in order to know when to reseed. (We should also expose it through a page shared read-only with userland for cheaper access, but until we do, let's let applications get at it through sysctl.) PR kern/58632: getentropy(2) and arc4random(3) do not reseed on VM fork arc4random.c: Fix test program. This isn't wired up anywhere, but let's reduce the bitrot. It was helpful in reminding me that kern.entropy.epoch was, for reasons I can't remember, restricted to privileged access.

This verifies that: - arc4random zeroes its state and reseeds itself on fork - arc4random reseeds itself on entropy consolidation (e.g., VM clone) - arc4random falls back to global state if it can't allocate local state because address space limits cause mmap to fail NOTE: This adds a new libc symbol __arc4random_global, but it's in the reserved namespace and only used by t_arc4random, so no libc minor bump.

1.217.2.1	02-Aug-2025	perseant	Sync with HEAD
1.2	12-Dec-1994	mycroft	Clean up deleted files.
1.1	11-Dec-1994	christos	- Changed all internal libc references of {v,}err{x,} and {v,}warn{x,} to __{v,}err{x,} and __{v,}warn{x,} - moved err.c to __err.c and added err.c which contains weak references for the above functions. - Reordered the functions in __err.c to avoid redeclarations and changed the varargs declarations to conform with the K&R style.
1.10	13-Sep-2005	christos	compat core reorg.
1.9	20-Jan-2005	kleink	Add ENOATTR (and a missing comma); noted by Takehiko NOZAKI.
1.8	07-Aug-2003	agc	Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22280, verified by myself.
1.7	27-May-2003	kleink	Add ETIME, per POSIX-2001.
1.6	09-Apr-2003	kleink	Change the strerror() string for ERANGE consistently to "Result too large or too small" and reword its intro(2) description to reflect the present use for non-numerical out-of-range errors; resolves Andrew Brown's PR standards/21004, the discussion of which was dramatically sped up by repeated whipping from Perry Metzger. :-)
1.5	12-Nov-2002	kleink	Review oversight: ENOSR: resource -> resources, which is what the standard says, and which fits the resource allocation failure better.
1.4	12-Nov-2002	skrll	Add the missing errno symbols that are defined in IEEE Std 1003.1-2001. The language message files need updating. Change reviewed and OK'd by Klaus Klein.
1.3	10-Mar-2000	kleink	branches: 1.3.6; Add an EILSEQ code (C99, first appeared in C90/AMD1), and update message catalogs where possible.
1.2	22-Mar-1999	kleink	Introduce EOVERFLOW.
1.1	30-Nov-1998	thorpej	Renamed sys_errlist, exported as a pointer, not an array, so that as new errors are added, the exported symbol size does not change. Update to include new errors.
1.3.6.1	12-Nov-2002	skrll	Catch up to -current.
1.46	13-Sep-2005	christos	compat core reorg.
1.45	19-Aug-2005	christos	64 bit inode changes
1.44	19-Jan-2005	mycroft	Use FD_CLOEXEC.
1.43	20-Jun-2004	jmc	Completely rework how tools/compat is done. Purge all uses/references to _NETBSD_SOURCE as this makes cross building from older/newer versions of NetBSD harder, not easier (and also makes the resulting tools 'different') Wrap all required code with the inclusion of nbtool_config.h, attempt to only use POSIX code in all places (or when reasonable test w. configure and provide definitions: ala u_int, etc). Reviewed by lukem. Tested on FreeBSD 4.9, Redhat Linux ES3, NetBSD 1.6.2 x86 NetBSD current (x86 and amd64) and Solaris 9. Fixes PR's: PR#17762 PR#25944
1.42	27-Oct-2003	lukem	branches: 1.42.2; Overhaul how `build.sh tools' are used: * Rename "config.h" to "nbtool_config.h" and HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H. This makes in more obvious in the source when we're using tools/compat/config.h versus "standard autoconf" config.h * Consistently move the inclusion of nbtool_config.h to before <sys/cdefs.h> so that the former can provide __RCSID() (et al), and there's no need to protect those macros any more. These changes should make it easier to "tool-ify" a program by adding: #if HAVE_NBTOOL_CONFIG_H #include "nbtool_config.h" #endif to the top of the source files (for the general case).
1.41	07-Aug-2003	agc	Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22280, verified by myself.
1.40	16-Sep-2002	briggs	Always use NetBSD's fts(3) in compat builds. Some systems (notably Red Hat 7.3, at least) do not have fts(3) implementations that work correctly with -D_FILE_OFFSET_BITS=64.
1.39	26-Feb-2002	tv	branches: 1.39.2; Add some more bits of host compatibility.
1.38	31-Jan-2002	tv	Roll in fixes to permit cross-compiling from non-NetBSD hosts. This round has been tested on Solaris/x86 and Linux hosts. * Add host tools cap_mkdb, ctags, m4, uudecode. * Protect __RCSID() and __COPYRIGHT() better. * Reduce the number of places that need to include "config.h", to keep sources closer to their "vanilla" versions. * Add more compat #defines and autoconf-checked functions.
1.37	28-Jan-2002	tv	Add hooks to make this compilable from src/tools/compat.
1.36	28-Nov-2001	christos	using -Wcast-qual and -Wwrite-strings reveals that we need to use const char * when we pass "" as an argument to a function. Too bad that they produce too many other spurious warnings too.
1.35	09-Jul-2001	christos	add fts_safe_changedir() function and use it everywhere. Idea from Todd Miller <millert@openbsd.org>
1.34	06-Jun-2001	christos	oops, make sure we close the file descriptor...
1.33	05-Jun-2001	christos	Fix problem reported by Kris Kennaway <kris@obsecurity.org>; In the default case fts(3) uses chdir("..") to ascend the tree. The sequence of chdir's can be intercepted by a malicious user who moves a subtree that fts is currently traversing to a higher level, thus making fts operate outside it's original starting directory.
1.32	05-Nov-2000	christos	branches: 1.32.2; add a lint comment.
1.31	07-Aug-2000	enami	- Test allocation failure. - Don't leave a pointer dangling on failure case. - Don't leak a file descriptor on failure case.
1.30	07-Aug-2000	enami	Nuke redundant test (though, gcc optimizer was clever enough not to emit redundant code).
1.29	07-Aug-2000	enami	- Wrap long lines. - Protect multi-statement macro with do {} while (0)
1.28	22-Jan-2000	mycroft	branches: 1.28.4; Delint. Remove trailing ; from uses of __weak_alias(). The macro inserts this if needed.
1.27	20-Sep-1999	lukem	back out the #ifdef _DIAGNOSTIC argument checks; too many people complained. _DIAGASSERT() is still retained.
1.26	16-Sep-1999	lukem	* use _DIAGASSERT() to check pointer arguments against NULL and file descriptors against -1 (as appropriate). * add actual checks which to detect stuff that would trigger_DIAGASSERT(), and attempt to return a sane error condition. * knf some code * remove some `register' decls. the first two items result in the addition of code similar to the following in various functions: _DIAGASSERT(path != NULL) #ifdef _DIAGNOSTIC if (path == NULL) { errno = EFAULT; return (-1); } #endif
1.25	27-Aug-1999	mycroft	Readd my change from fts.c rev 1.10, which was incorrectly removed in rev 1.19 (HI CHRISTOS!): Avoid extra stat()s if a link count of 1 is returned for directories but the d_type field is filled in.
1.24	27-Aug-1999	mycroft	Adjust fts_pow2() for LP64 before Ross bricks me.
1.23	27-Aug-1999	mycroft	GC one line of unneeded code.
1.22	27-Aug-1999	mycroft	Fix the comment above fts_palloc(). Also, fail with ENOMEM if fts_pathlen would overflow, rather than silently truncating the path.
1.21	27-Aug-1999	mycroft	Avoid memory leaks when realloc() fails (by storing the return value in a temporary, and testing it before assigning it; fts_close(3) will deallocate the old memory).
1.20	27-Aug-1999	mycroft	Fix multiple problems in the FTS_NOCHDIR case: * There was an off-by-one error that caused the addition of a NUL or slash in fts_build() to overwrite other memory. * After fts_palloc(), we need to reset `cp' so that it points to the new path name buffer; otherwise the addition of the file name before calling fts_stat() could lose. Also, fix stupidity in the fts_palloc() interface. We don't want N bytes more than the current buffer size; we want N bytes more than the current length. Just pass in the new size, since we can't figure it out easily here.
1.19	27-Aug-1999	mycroft	Allocate the path name buffer by powers of 2.
1.18	26-Aug-1999	mycroft	Minor change to previous.
1.17	26-Aug-1999	mycroft	Fix 3 bugs: * When not using FTS_NOCHDIR, fts_accpath == fts_name. fts_padjust should not try to move fts_accpath in this case. * Previous entries at the same level also need to be adjusted. * A bug was introduced in rev 1.8 (HI CHRISTOS!!) that caused the maxlen comparison to always fail (due to type promotions) when sp->fts_pathlen == cur->fts_pathlen -- thus causing memory stompage.

1.1	30-Jun-2002	bjh21	branches: 1.1.2; Version times() so that programs compiled before the recent change to make sysconf(_SC_CLK_TCK) return hz will work. In detail: __times13() returns values scaled by hz. times() returns values scaled by 100. <sys/times.h> renames times() to __times13(). _SC_CLK_TCK has changed from 3 to 39. sysconf(3) returns 100. sysconf(39) returns hz.

Because of how the callable versions are created, by CPP trickery and inclusion of another .c file, we cannot allow the included .c file to pull in "namespace.h", since it undoes the CPP trickery we have performed. Introduce a CPP macro that prevents the included .c file from pulling in "namespace.h".

1.3	23-Mar-1995	jtc	Changed name of __weak_reference() to __indr_reference(). They really are indirect references, and I want to add a real __weak_reference() macro to <machine/cdefs.h> soon.

1.2	12-Dec-1994	mycroft	Clean up deleted files.
1.1	10-Oct-1994	jtc	Renamed sys_errlist[] and sys_nerr to __sys_errlist[] and __sys_nerr. The traditional API of sys_errlist[] and sys_nerr is provided by weak references if they are supported. Otherwise, we're forced to have to have two copies of the error message string table in the library. Fortunately, unless a program uses both sys_errlist[] and strerror(), only one of the copies will be linked into the executable. This is all to provide an clean namespace as required by ANSI. I've done the same for sys_siglist[], even though it is not required, to be consistant.
1.14	20-Jan-2024	christos	Catch up with all the lint warnings since exit on warning was disabled. Disable 'missing header declaration' and 'nested extern' warnings for now.

1.8	10-Dec-1999	explorer	revert this file, the changes I made were quite unnecessary.
1.7	03-Dec-1999	explorer	Put the function prototype back. Grr.
1.6	03-Dec-1999	explorer	Do this a bit differently. On platforms where we can use weak aliases, use __weak_alias(__errno, __errno_func); and on platforms where we cannot, just compile the function as __errno, since on those platforms we cannot make libc thread-safe, at least using this trick. Are there any platforms where we cannot do __weak_alias() anymore?
1.5	03-Dec-1999	explorer	Make __errno() be a weak alias for __errno_func(), so thread packages can actually override what plain old 'errno' looks like.
1.4	30-Jul-1997	jtc	branches: 1.4.8; Fix files using old TNF copyright notice
1.3	13-Jul-1997	christos	Move the #undef errno where it is actually needed.

1.4.8.1	27-Dec-1999	wrstuden	Pull up to last week's -current.
1.9.2.2	30-Dec-2001	nathanw	Instead of doing the thread-specific-date and once-initializer song and dance here, just call the new thr_errno() when in threaded mode. This avoids an ugly interdependancy between malloc(), which wants to set errno (during initialization and errors), and errno, which used to want to malloc() the thread-specific storage.
1.9.2.1	08-Aug-2001	nathanw	Make errno thread-specific when necessary.
1.12.18.1	18-May-2008	yamt	sync with head.

1.6	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

This sidesteps any need for dynamically sized memory in userland to resolve sysctl names to read it out, or for a new syscall interface to sysctl resolution by name.

This way you can swap out crypto_le32enc/dec to test either byte order on any machine, e.g. for generating the test vectors. And if we ever decide that it's not worthwhile to take advantage of the purely nondeterministic nature of the API to make this have potentially less performance penalty on big-endian systems (which I'm not sure has ever been measured anyway), it'll all continue to work under #define crypto_le32enc le32enc #define crypto_le32dec le32dec with all the _BYTE_ORDER == _BIG_ENDIAN conditionals removed from the self-tests.

This is a private symbol, not designed for use outside NetBSD, and the API is not intended to be stable (yet) -- I just took the existing purely internal structure (struct atfork_callback) and reused it for this API without changing any of the calling-side logic. We could change it, e.g. to use a single structure per call, to make the API a little less unwieldy, at the cost of microscopically more storage and runtime for the users that don't use all three callbacks; to be considered in a future change. We might reasonably use __libc_atfork in libpthread for use in the pthread_tsd_init constructor, in order to be confident it never attempts malloc(3), but let's do that in a separate commit just in case anything goes awry with that plan.

1.12	03-Jan-2001	lukem	* Change __diagassert13() so that by default it only syslogs the error (it used to syslog and also send to stderr). This behaviour can be changed by setting $LIBC_DIAGASSERT to a string containing one or more of the following letters: a abort() after syslog and/or print to stderr A opposite of a e print assertion message to stderr E opposite of e l log assertion message to syslog L opposite of l This allows per-process control of the _DIAGASSERT() behaviour (e.g, if you want to abort() after the assertion is raised) by modifying the environment before starting the process. Note that __DIAGASSERT() is still a no-op unless libc is compiled with -D_DIAGNOSTIC. * Implement __assert()/__diagassert() by calling __assert13()/__diagassert13() with a function of NULL, reducing unnecessary code duplication

1.6	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

Both the extra diagnostics _and_ LIBC_ALLOWCTYPEABUSE are new in 11. The extra diagnostics were not added in 10 (unless someone went ahead and pulled them up while I wasn't looking!). LIBC_ALLOWCTYPEABUSE doesn't guarantee that the program won't crash; it just makes that depend on factors such as address space layout randomization -- where the ctype tables appear in memory relative to non-readable pages.

1.22	29-Mar-2025	riastradh	libc: Restore ELF symbol sizes for _C_ctype_tab_ &c. This is needed for dynamic position-dependent executables that refer directly to _C_type_tab_ to get correct copy relocations to see the table content. Unfortunately, such executables won't get a guard page. Fortunately, referring to _C_ctype_tab_ directly (and not the indirection _ctype_tab_ as the ctype(3) macros do) is very weird and unlikely to happen in the real world (none of the public interfaces use it; it is exported for libc++.so/libstdc++.so to use, but those aren't pies). So missing the guard page in this case is probably not so bad. The symbol sizes are also needed for, e.g., gdb to nicely identify addresses that lie in the table.

1.10	05-Oct-1993	jtc	Due to an 8-bit attribute table and 9 bits of attributes, I've had to remove the _B attribute from the "horizontal tab" position, and change the isblank function to explicitly test against space and tab. When I finish merging the 4.4 runes code, this table will have to grow to 16 bit entries, as several more attributes have been introduced. I'm making this change so existing libraries will continue working for the next (little) while.

1.7	23-Aug-1993	jtc	Moved toupper and tolower tables from ctype_.c to their own files --- I received complaints about using shorts in the table (but i need a range of -1..255), so now the tables will not be used unless either toupper() or tolower() (and soon, setlocale()) are used. This can save up to 514 bytes. In toupper_.c and tolower_.c make sure that our assumption of EOF == -1 holds. Fixed bug where _toupper_tab_ was initialized pointing to _C_tolower_tab.
1.6	21-Aug-1993	jtc	_ctype_, _tolower_tab_, and _toupper_tab_ are now pointers to the tables. The tables have been renamed to _C_ctype_, _C_tolower_, and _C_toupper_ as they are tables for the C locale. When switching to a new locale, the pointers will be set to point to tables specific to the new locale.

1.4	06-Aug-1993	jtc	Added C locale specific translation tables for toupper and tolower. When locales are fully supported, toupper and tolower will refer to this, or a locale specific table, through pointers.
1.3	06-Aug-1993	jtc	Use const qualifier with _ctype_ table. Smart compilers can then store it in the text segment. When we implement locales, the isctype macros/functions will reference this table (or a locale specific table) through a pointer, but for right now, it continues to reference the _ctype_ table directly.

1.8	22-Jan-2000	mycroft	Delint. Remove trailing ; from uses of __weak_alias(). The macro inserts this if needed.
1.7	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

Consider also adding some additional notes. For instance, I left the semantics about "." and ".." out. The returned errno's should be enumerated as well.

The new semantics are considered less hostile/more useful by most programs which use basename(3) and/or dirname(3) (several programs in the NetBSD tree reimplement basename()/dirname() themselves to avoid modification of the input argument). This new implementation truncates results to PATH_MAX. The Std does not address this in the static storage case. However since PATH_MAX is the maximum pathname length in the Std, this should not be a problem in practice. Nontheless, it is noted in the BUGS section. See the basename(3)/dirname(3) regression tests in src/regress/lib/libc. Inspired by discussion with Niels Provos, related to PR 18647.

1.33	22-Jun-2005	he	Fix the toolification of disklabel by using the nbinclude namespace under HAVE_NBTOOL_CONFIG_H for disktab.h as well. This means disktab.h has to be installed in the nbinclude include directory. (Failure mode: with TOOLDIR as a subdirectory of /usr, the host's disktab.h got picked up, and not the in-tree copy.) Reviewed by dyoung.

To avoid clashes with a build-host's header files, especially on *BSD, the host-tools versions of fdisk and disklabel search for #includes such as disklabel.h, disklabel_acorn.h, disklabel_gpt.h, and bootinfo.h in a new #includes namespace, nbinclude/. That is, they #include <nbinclude/sys/disklabel.h>, <nbinclude/machine/disklabel.h>, <nbinclude/sparc64/disklabel.h>, instead of <sys/disklabel.h> and such. I have also updated the system headers to #include from nbinclude/-space when HAVE_NBTOOL_CONFIG_H is #defined.

1.27	07-Jul-2000	itohy	branches: 1.27.2; Passing "char" values to ctype(3) functions is problematic. If an argument of a ctype function is outside "unsigned char" and if it is not EOF, the behavior is undefined. The isascii(3) is the sole exception of above and it was used to be used to check a value was valid for other ctype functions in ancient systems. On modern systems, the ctype functions take all values of "unsigned char", and this check is obsolete and even wrong for non-ASCII systems. However, we leave the isascii() untouched for now, so as not to change the current behavior.

1.15	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

This makes in more obvious in the source when we're using tools/compat/config.h versus "standard autoconf" config.h * Consistently move the inclusion of nbtool_config.h to before <sys/cdefs.h> so that the former can provide __RCSID() (et al), and there's no need to protect those macros any more. These changes should make it easier to "tool-ify" a program by adding: #if HAVE_NBTOOL_CONFIG_H #include "nbtool_config.h" #endif to the top of the source files (for the general case).

Because of how the callable versions are created, by CPP trickery and inclusion of another .c file, we cannot allow the included .c file to pull in "namespace.h", since it undoes the CPP trickery we have performed. Introduce a CPP macro that prevents the included .c file from pulling in "namespace.h".

1.1	10-Oct-1994	jtc	branches: 1.1.1; Renamed sys_errlist[] and sys_nerr to __sys_errlist[] and __sys_nerr. The traditional API of sys_errlist[] and sys_nerr is provided by weak references if they are supported. Otherwise, we're forced to have to have two copies of the error message string table in the library. Fortunately, unless a program uses both sys_errlist[] and strerror(), only one of the copies will be linked into the executable. This is all to provide an clean namespace as required by ANSI. I've done the same for sys_siglist[], even though it is not required, to be consistant.

1.29.4.1	13-Apr-2020	martin	Mostly merge changes from HEAD upto 20200411
1.9	03-Jul-1996	jtc	Split all exec*() functions out of exec.c into their own files.
1.8	03-Jul-1996	jtc	Added a new VA_START macro to hide the differences between varargs.h and stdargs.h. This cleans up a lot of conditionals throughout this file.
1.7	14-Dec-1995	jtc	Changed to use alloca() instead of malloc() to allocate argument vectors. Programs that don't use malloc()/free() (ie. provide their own allocation scheme atop sbrk()) should still be able to use exec*.
1.6	27-Feb-1995	cgd	merge with Lite, keeping local changes. Also use new Id format.
1.5	24-Nov-1993	jtc	branches: 1.5.4; Change C library functions to use strchr() and strrchr() instead of index() and rindex(). This will allow (strict {ANSI, POSIX, XOPEN}) applications to redefine index() and rindex() without effecting the library internals.
1.4	22-Oct-1993	pk	In execvp(): `eacces' did not get initialized when path name contains a '/'. This causes the wrong error to be reported when execve() fails.
1.3	26-Aug-1993	jtc	Declare rcsid strings so they are stored in text segment.
1.2	30-Jul-1993	mycroft	Add even more RCS frobs.

1.5.4.2	26-Apr-1995	jtc	Namespace protect exec*() functions.
1.5.4.1	26-Apr-1995	jtc	#include "namespace.h"
1.18	20-Jan-2024	christos	Catch up with all the lint warnings since exit on warning was disabled. Disable 'missing header declaration' and 'nested extern' warnings for now.
1.17	30-Jun-2011	joerg	Drop special cases for i386 and m68k. It is not a validate assumption that the address of an argument is at the same stack slot the caller placed in it. It is perfectely valid to copy it into the local frame first.
1.16	09-Jan-2008	simonb	Remove support for NetBSD/pc532.
1.15	20-Mar-2006	he	branches: 1.15.10; Now that we use an errno constant, we need <errno.h>.
1.14	20-Mar-2006	rtr	check the return of alloca() if it fails set errno = ENOMEM and fail execl(). approved by christos@ resolves pr29671
1.13	29-Nov-2005	christos	cleanup casts and KNF.
1.12	29-Nov-2005	christos	WARNS=4
1.11	07-Aug-2003	agc	Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22280, verified by myself.
1.10	04-Mar-2003	nathanw	Don't acquire __environ_lock around exec() calls; nothing requires that these calls be thread-safe with respect to the environment, and it causes serious problems for threaded applications which call vfork() and exec() (including indirectly, via popen() or system()). Acquire and release __environ_lock in the parent in popen() and system() to play safe and provide the child with a stable environment. __environ_lock should also have an atfork() handler; still under development.
1.9	18-Jan-2003	thorpej	Merge the nathanw_sa branch.
1.8	26-May-2002	wiz	__STDC__ is always defined on NetBSD.
1.7	22-Jan-2000	mycroft	branches: 1.7.6; Delint. Remove trailing ; from uses of __weak_alias(). The macro inserts this if needed.
1.6	11-Sep-1998	kleink	Add a multiple-reader/single-writer lock to protect environ.
1.5	20-Nov-1997	mjacob	argv alloca'd is too short. Alloc an extra member.
1.4	21-Jul-1997	jtc	branches: 1.4.2; If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.
1.3	13-Jul-1997	christos	Fix RCSID's
1.2	04-Jul-1996	jtc	branches: 1.2.2; Thanks to the calling conventions used by some cpus, the argument lists passed to the execl(), execle(), and execlp() functions are in the form of the argument vector to be passed to execve(). On these architectures, it is unnecessary to count the number of arguments, allocate space on the stack, copy the arguments, etc. The vector already on the stack can be used instead. When some arguments are passed in registers (like most RISC CPU's), it should be possible to allocate stack space adjacent such that the registers can be copied to that memory. After that, the same approach described above can be used. This change takes advantage of this on the i386, m68k, and ns32k. It is probably true on the vax, but I am unable to check. RISC CPU's probably need assembly language implementations to ensure everything is placed exactly as needed when registers are copied to the stack...

1.2	05-Jan-2018	kamil	Include namespace.h in a few of libc source files The NetBSD Standard C Library uses internally some of its functions with a mangled symbol name, usually "_symbol". The internal functions shall not use the global (public) symbols. This change finishes elimination of usage of the global name of the following symbols: - close -> _close - execve -> _execve - fcntl -> _fcntl - setcontext -> _setcontext - wait6 -> _wait6 - write -> _write - writev -> _writev Sponsored by <The NetBSD Foundation>
1.1	07-Feb-2017	kamil	branches: 1.1.2; 1.1.4; Mark exect(3) obsolete and bind it to plain execve(2) on all platforms The original exect(2) from BSD4.2 was enabling bit for tracing (single-step mode) and calling execve(2). The purpose of it was to generate a signal for a tracer once the application will change its image to a new program. This approach no longer works as: - exect(2) traces (single-steps) libc and it requires hundreds or thousands steps before entering a new image - it's vax and x86 specific code - this functionality has been moved to the kernel - once a process is traced it will generate SIGTRAP with si_code TRAP_EXEC and route it to its debugger - the side effects and unportability make this interface unusable - there are no known users of this interface - it apparently never worked better since day0 of NetBSD ("day0 bug") Users are requested to move to other execve(2) variants. Calling current execve(2) as it is the most similar behavior to this one from BSD4.2. Discussed several times on mailing lists and in PR/51700. Add warning to exect(3) telling about marking this function obsolete. This function is prepared to be removed in next libc major bump. Sponsored by <The NetBSD Foundation>

It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

1.22	04-Mar-2003	nathanw	Don't acquire __environ_lock around exec() calls; nothing requires that these calls be thread-safe with respect to the environment, and it causes serious problems for threaded applications which call vfork() and exec() (including indirectly, via popen() or system()). Acquire and release __environ_lock in the parent in popen() and system() to play safe and provide the child with a stable environment. __environ_lock should also have an atfork() handler; still under development.

1.16	22-Jan-2000	mycroft	branches: 1.16.6; Delint. Remove trailing ; from uses of __weak_alias(). The macro inserts this if needed.
1.15	20-Sep-1999	lukem	back out the #ifdef _DIAGNOSTIC argument checks; too many people complained. _DIAGASSERT() is still retained.
1.14	16-Sep-1999	lukem	* use _DIAGASSERT() to check pointer arguments against NULL and file descriptors against -1 (as appropriate). * add actual checks which to detect stuff that would trigger_DIAGASSERT(), and attempt to return a sane error condition. * knf some code * remove some `register' decls. the first two items result in the addition of code similar to the following in various functions: _DIAGASSERT(path != NULL) #ifdef _DIAGNOSTIC if (path == NULL) { errno = EFAULT; return (-1); } #endif
1.13	16-Sep-1999	lukem	revert previous (as per klaus). will diagassert() name == NULL check instead...

1.13	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

1.4	24-Nov-1993	jtc	Change C library functions to use strchr() and strrchr() instead of index() and rindex(). This will allow (strict {ANSI, POSIX, XOPEN}) applications to redefine index() and rindex() without effecting the library internals.

1.20.2.2	22-Oct-1997	thorpej	Pull up from trunk: New hacks to make libc work painlessly without bumping the major number: use type func(arg1s) asm("emitted_name") gcc mechanism. Suggested by Bill Sommerfeld. Allow the old-name functions to be compiled from the same source file as the renamed functions, and add some #error directives to force the issue with weak symbols for renamed functions when we support weak symbols in the C library.

1.10	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

These changes should make it easier to "tool-ify" a program by adding: #if HAVE_NBTOOL_CONFIG_H #include "nbtool_config.h" #endif to the top of the source files (for the general case).

1.12	14-Mar-1998	lukem	backout parts of the lite2 merge; it causes undesirable lossage: * $PWD was used if it appeared ``correct''. this `enhancment' was not documented in getcwd(3), and caused problems for pwd(1) (which uses getcwd(3)), and in turn <bsd.obj.mk> (which uses pwd) when $PWD is set to the logical path instead of the real path (e.g, symlink /usr/src -> /z/NetBSD-current/src). [$PWD is set to the logical path by tcsh(1) with set symlinks=expand] * as getcwd() without the $PWD code is just a wrapper to getcwd_physical(), rename the latter to the latter. hack realpath() to use the getcwd(). yet another case of `it was a good idea, but...'

1.7	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

1.4	31-May-2022	riastradh	branches: 1.4.2; libc: Reintroduce getentropy. This was introduced two years ago when the getrandom/getentropy API question was still open, and removed because the discussion was ongoing. Now getentropy is more widely adopted and soon to be in POSIX. So reintroduce the symbol into libc since we'll be keeping it anyway. Discussion of details of the semantics, as interpreted by NetBSD, is ongoing, but the symbol needs to get in before the netbsd-10 branch. The draft POSIX text is (https://www.opengroup.org/austin/docs/austin_1110.pdf): SYNOPSIS #include <unistd.h> int getentropy(void *buffer, size_t length); DESCRIPTION The getentropy() function shall write length bytes of data starting at the location pointed to by buffer. The output shall be unpredictable high quality random data, generated by a cryptographically secure pseudo-random number generator. The maximum permitted value for the length argument is given by the {GETENTROPY_MAX} symbolic constant defined in <limits.h>. RETURN VALUES Upon successful completion, getentropy() shall return 0; otherwise, -1 shall be retunred and errno set to indicate the error. ERRORS The getentropy() function shall fail if: [EINVAL] The value of length is greater than {GETENTROPY_MAX}. The getentropy() function may fail if: [ENOSYS] The system does not provide the necessary source of entropy. RATIONALE The getentropy() function is not a cancellation point. Minor changes from the previous introduction of getentropy into libc: - Return EINVAL, not EIO, on buflen > 256. - Define GETENTROPY_MAX in limits.h. The declaration of getentropy in unistd.h and definition of GETENTROPY_MAX in limits.h are currently conditional on _NETBSD_SOURCE. When the next revision of POSIX is finalized, we can expose them also under _POSIX_C_SOURCE > 20yymmL as usual -- and this can be done as a pullup without breaking existing compiled programs.

1.1	06-May-2020	nia	Add getentropy() to libc - a simple wrapper to access the kernel CSPRNG. Posted to tech-userlevel@ a week ago and reviewed by riastradh@. GETENTROPY(3) Library Functions Manual GETENTROPY(3) NAME getentropy - fill a buffer with high quality random data LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <unistd.h> int getentropy(void *buf, size_t buflen); DESCRIPTION The getentropy() function fills a buffer with high quality random data, suitable for seeding cryptographically secure psuedorandom number generators. getentropy() is only intended for seeding random number generators and is not intended for use by regular code which simply needs secure random data. For this purpose, please use arc4random(3). The maximum value for buflen is 256 bytes. IMPLEMENTATION NOTES getentropy() reads from the sysctl(7) variable kern.arandom. RETURN VALUES The getentropy() function returns 0 on success, and -1 if an error occurred. ERRORS getentropy() will succeed unless: [EFAULT] The buf argument points to an invalid memory address. [EIO] Too many bytes were requested. SEE ALSO arc4random(3), rnd(4) STANDARDS The getentropy() function is non-standard.

PR kern/58632: getentropy(2) and arc4random(3) do not reseed on VM fork arc4random(3): Reseed if system entropy epoch changes. This can happen, for example, if the system is a VM instance, and the VM is cloned. This incurs the cost of a system call on every arc4random call, which is unfortunate, but 1. we don't currently have a (machine-independent) mechanism for exposing a read-only page to userland shared by the kernel to enable a cheaper access path to the entropy epoch; and 2. the algorithm here -- a simple application of ChaCha -- is likely also a bottleneck and could be much cheaper by (a) using sys/crypto/chacha for machine-dependent vectorized ChaCha code, and (b) filling a buffer (somewhere between a cipher block and a page) in a batch at a time, instead of running ChaCha to generate only 32 bytes at a time. So although this might be a performance hit, the security benefit is worthwhile and we have a clear path to do better than reversing the performance hit later.

1.54	06-Jan-2005	lukem	branches: 1.54.2; Rename various "internal" variables and functions and make non-static so other internal libc source files can use these (including getgroupmembership(3)). Be more consistent in the API that the __grscan_<source>() methods use. In __grscan_compat() support an optional custom 'search' function used when a "+" lookup is required. Normally this will be getgrent() from group_compat, but getgroupmembership(3) will use a tailored compat search routine for efficiency.
1.53	10-Nov-2004	lukem	Use the common __nsdefaultFOO rather than private defaultFOO duplicates.

1.50	24-Oct-2004	lukem	Protect access to all public functions via a mutex as some of the backends are not reentrant (such as compat getgr*_r, because it uses the non reentrant _{dns,nis}_getgrent() backends to implement `+group').
1.49	04-Oct-2004	lukem	Overhaul the use of nsdispatch(3) by public APIs so that the back-end methods use va_list in a manner that is directly related to the public API. This makes it much easier to write dynamic nsswitch backends for getgrent(3). Per my proposal on tech-userlevel. Implement getgrgid_r() and getgrnam_r() APIs per the POSIX 1003.1, 2004 Ed. These aren't fully reentrant or threadsafe yet, because the compat stuff currently uses non-reentrant data sources (getnetgrent(3), getgrent(3)), and there is probably some locking to be improved in the backends. This will be fixed in the near future. We also need to add _SC_GETGR_R_SIZE_MAX to sysconf(3).

1.21	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

XXX: in the case where the given array is too small and -1 is returned, the returned ngroups will be too large by a factor of the difference between the given size and the number of matches. this is not considered to be a major problem, since it's still going to be a smaller figure than what the previous (non suppressive) behaviour returned.

1.8	02-Feb-1998	perry	merge/update to lite-2
1.7	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

1.5	20-Apr-2021	christos	Instead of compiling files with -fcommon, create an include file and declare the 3 symbols that need to be common using an attribute. Put all the 3 symbol definitions in libc in one place (initfini.c). Reviewed by joerg@
1.4	06-Oct-2011	christos	Provide symbol definitions for environ and __progname. These are duplicate definitions to the ones provided by csu, but harmless since the linker resolves them. There are 3 non weak data symbols provided in crt0.o: D __progname [initialized data, assigned to ""] B __ps_strings [BSS since assigned to 0] C environ [common, uninitialized] __ps_strings had already a second definition in libc (in BSS), now we added __progname and __ps_strings (in BSS). To get rid of the duplicate definition, we can remove them from csu, and move the assignments to libc. This is done so that libc has no undefined symbols so that linker maps that want to do: ... local: *; ... don't end up producing link failures for libc.

This makes it much easier to write dynamic nsswitch backends for getpwent(3). Per my proposal on tech-userlevel. Implement getpwgid_r() and getpwnam_r() APIs per the POSIX 1003.1, 2004 Ed. These aren't fully reentrant or threadsafe yet, because the compat stuff currently uses non-reentrant data sources (getnetgrent(3), getpwent(3)), and there is probably some locking to be improved in the backends. This will be fixed in the near future. We also need to add _SC_GETPW_R_SIZE_MAX to sysconf(3). Fix the compat `+' prototype override so getpwnam(3) and getpwuid(3) DTRT.

1.23	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

1.13	09-May-2004	kleink	There are two instances of getsubopt.c, one in gen, which came by the ways of 386BSD, and one in stdlib, which is from Lite-2. The former was picked up by the build process and has seen a little more maintenance while the latter's location is "right", so bring the latter up to par with the former and dispose of the (now) latter. Reported by David A. Holland in PR lib/25160, which is worded in a far less mind-boggling fashion than the above.

1.7	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

1.18	07-Jul-2000	itohy	Passing "char" values to ctype(3) functions is problematic. If an argument of a ctype function is outside "unsigned char" and if it is not EOF, the behavior is undefined. The isascii(3) is the sole exception of above and it was used to be used to check a value was valid for other ctype functions in ancient systems. On modern systems, the ctype functions take all values of "unsigned char", and this check is obsolete and even wrong for non-ASCII systems. However, we leave the isascii() untouched for now, so as not to change the current behavior.

1.7	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

Be more consistent in the API that the __grscan_<source>() methods use. In __grscan_compat() support an optional custom 'search' function used when a "+" lookup is required. Normally this will be getgrent() from group_compat, but getgroupmembership(3) will use a tailored compat search routine for efficiency.

So simply use the unscaled value (the raw number). While here, also avoid returning values that are larger than the buffer len ... while it would be nice to be able to find out how big the buffer should be so the data will fit, the interface doesn't really allow that (the buffer length passed in controls the scaling - at least when auto scaling) and the code already does "return -1" when it detects the buffer length is too small, even before it works out how much would have been needed. So, rather than returning a value > len (while truncating the result to fit in len ... all courtesy of snprintf()) return -1 in this case as well. Also, allow suffix==NULL (meaning "") - there's no reason not to, and requiring users to pass in an explicit "" is not useful.

It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

1.29	15-Sep-2025	riastradh	ctype(3): New environment variable LIBC_ALLOWCTYPEABUSE. If set, this does not force the ctype(3) functions to crash when passed invalid inputs -- instead, they will return nonsense results, and possibly print warnings to stderr, as is their right in implementing undefined behaviour. The nature of the nonsense results is unspecified. Currently, is*() will always return true (even if that leads to mutually contradictory conclusions, like isalpha and isdigit, or isgraph and isblank), and tolower/toupper() will always return EOF. But perhaps in the future the results may be randomized. This way, if an application like firefox crashes on ctype abuse, you can opt to accept the consequences of nonsense results instead by running `env LIBC_ALLOWCTYPEABUSE= firefox' until the application is fixed.

(I opted to unconditionally abort so that you get the feedback about undefined behaviour even if you don't run with LIBC_DIAGASSERT set in the environment. Since it's undefined behaviour we are allowed to do this unconditionally, of course!) PR lib/58208: ctype(3) provides poor runtime feedback of abuse
1.27	29-Mar-2025	riastradh	ctype(3): Summon a demon from caller's nose if abused out-of-line. This way, applications which opt for the out-of-line functions will crash with a potentially meaningful message to stderr if they pass inputs on which the ctype(3) functions are undefined. (If fd 2 is something else, tough -- this is nasal demon country, and they fly where they please, application intent be damned.) This probably won't catch many applications -- but it might catch C++ applications at runtime that can't be caught at build-time because they eschew the macros. The cost is a single predicted-not-taken branch -- it's checking c for membership in the interval [-1,0xff] when we're already computing c + 1, so it can be a single unsigned-compare. By deferring the message and abort to an out-of-line function we avoid a stack frame in the good case. And this is for the unlikely, out-of-line versions of the ctype(3) functions -- most applications get the inline macros. So I'm not concerned by the prospect of a performance impact. Update the tests so they recognize SIGABRT as noisy failure too, not just SIGSEGV. PR lib/58208: ctype(3) provides poor runtime feedback of abuse

[libc] - localeio.[ch] and lc.[ch] in src/lib/libc/locale was replaced by new locale-db implementation using citrus_db backend, see src/lib/libc/citrus/citrus_lc_.[ch]. - add citrus_bcs_strtou?l.c. don't use strtou?l locale implementation internally, because they're locale-aware function. - add some stubs for multi-locale issue, see {current,global}_locale.c. - remove some obsolete file, setrunelocale.c, ___runetype_mb.c. - remove __savectype() from ctypeio.[ch]. [tools] - mklocale(1): add new option ``-t'' that generates new style LC_{MONETARY,NUMERIC,TIME,MESSAGES} locale-db format. - chrtbl(1): added ctypeio.[ch] for __savectype(). [locale-db] - added en_US.US-ASCII locale. - removed some shareable locale definition file: en_US.US-ASCII -> en_US.ISO8859-1, en_US.UTF-8 zh_CN.eucCN -> zh_CN.GB18030 and more...see src/share/locale//Makefile. - remove obsoleted locale sr_YU, added new locale sr_ME, sr_RS. - change locale name ja_JP.ISO2022-JP -> ja_JP.ISO-2022-JP* for X11's locale.alias file alignments. - fix regression test, wrong wcs?width(3), NAN/INF usage. i tested release-build following arch: i386, amd64, hpc{mips,arm,sh}, sparc64, vax. citrus_lc_.[ch] also can read old-plain-text style locale-db. so that backward compatibility is keeped, but lc.[ch] can't read new citrus_db'ed locale-db and localeio.c never check sanity, so forward compatibility is broken ;-< old mklocale(1) doesn't know -t option, so you have to rebuild toolchain.
1.16	07-Aug-2003	agc	branches: 1.16.38; 1.16.40; Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22280, verified by myself.
1.15	12-Sep-1999	kleink	Move the function implementations of (the non-ANSI) isascii() and toascii() into separate modules to avoid namespace clashes.
1.14	13-Jul-1997	christos	Fix RCSID's
1.13	27-Feb-1995	cgd	merge with Lite, keeping local changes. Fix up Id format, etc.
1.12	17-May-1994	cgd	copyright foo
1.11	11-Nov-1993	jtc	First pass at getting a clean compile with "gcc -Wall", mostly explictly declaring function return values, etc.
1.10	05-Oct-1993	jtc	Due to an 8-bit attribute table and 9 bits of attributes, I've had to remove the _B attribute from the "horizontal tab" position, and change the isblank function to explicitly test against space and tab. When I finish merging the 4.4 runes code, this table will have to grow to 16 bit entries, as several more attributes have been introduced. I'm making this change so existing libraries will continue working for the next (little) while.
1.9	14-Sep-1993	jtc	Implement C version of isblank.
1.8	05-Sep-1993	mycroft	Separate the toupper() and tolower() functions so the tables really don't get included unless you need them.
1.7	26-Aug-1993	jtc	Declare rcsid strings so they are stored in text segment.
1.6	23-Aug-1993	cgd	use "_to_tab_" rather than "_to_table_" -- table is defined as the former
1.5	06-Aug-1993	jtc	Use C locale specific traslation tables for toupper and tolower. Direct access to the tables is to be replaced by a pointer to tables for the current locale.
1.4	06-Aug-1993	jtc	Provide function versions of isascii() and toascii().
1.3	30-Jul-1993	mycroft	Remove patchkit lossage, and RCS frob, and make tolower() and toupper() a little faster.
1.2	21-Mar-1993	cgd	after 0.2.2 "stable" patches applied
1.1	21-Mar-1993	cgd	branches: 1.1.1; Initial revision
1.1.1.1	21-Mar-1993	cgd	initial import of 386bsd-0.1 sources

If set, this does not force the ctype(3) functions to crash when passed invalid inputs -- instead, they will return nonsense results, and possibly print warnings to stderr, as is their right in implementing undefined behaviour. The nature of the nonsense results is unspecified. Currently, is*() will always return true (even if that leads to mutually contradictory conclusions, like isalpha and isdigit, or isgraph and isblank), and tolower/toupper() will always return EOF. But perhaps in the future the results may be randomized. This way, if an application like firefox crashes on ctype abuse, you can opt to accept the consequences of nonsense results instead by running `env LIBC_ALLOWCTYPEABUSE= firefox' until the application is fixed. PR lib/58208: ctype(3) provides poor runtime feedback of abuse ctype(3): Document LIBC_ALLOWCTYPEABUSE. If this is pulled up to netbsd-11, we should tweak the text to make it apply to 11 too.

1.14	17-Apr-2008	apb	branches: 1.14.10; Refer to the CAVEATS section of ctype(3) for more information.
1.13	18-Jan-2007	rillig	Added a reference to ctype.3. What's the value of having that page at all if it isn't referenced by others? Suggested by Slava Semushin via private mail.
1.12	05-Oct-2006	rillig	Fixed the wording of the <ctype.h> character classification functions by always using "function" instead of "macro". Changed "undefined result" into "undefined behavior" for argument values outside the valid range.

1.12	18-Jan-2007	rillig	Added a reference to ctype.3. What's the value of having that page at all if it isn't referenced by others? Suggested by Slava Semushin via private mail.
1.11	05-Oct-2006	rillig	Fixed the wording of the <ctype.h> character classification functions by always using "function" instead of "macro". Changed "undefined result" into "undefined behavior" for argument values outside the valid range. Since the character table is allocated via malloc(), it _may_ happen that it starts at a page boundary, so that negative values for the argument result in a segmentation fault. In that case, there is no result at all.

It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls.

1.2	27-Sep-1996	cgd	slightly tune what gets compiled in: On the Alpha, we need ECOFF and ELF64. On other architectures only include a.out support, since we don't know whether or not they'll have the headers necessary for ECOFF and/or ELF, and since they only want a.out for now (execpt the mips archs, but they do Special things).

Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls.

1.31	26-Jun-2011	christos	branches: 1.31.2; * Arrange for interfaces that create new file descriptors to be able to set close-on-exec on creation (http://udrepper.livejournal.com/20407.html). - Add F_DUPFD_CLOEXEC to fcntl(2). - Add MSG_CMSG_CLOEXEC to recvmsg(2) for unix file descriptor passing. - Add dup3(2) syscall with a flags argument for O_CLOEXEC, O_NONBLOCK. - Add pipe2(2) syscall with a flags argument for O_CLOEXEC, O_NONBLOCK. - Add flags SOCK_CLOEXEC, SOCK_NONBLOCK to the socket type parameter for socket(2) and socketpair(2). - Add new paccept(2) syscall that takes an additional sigset_t to alter the sigmask temporarily and a flags argument to set SOCK_CLOEXEC, SOCK_NONBLOCK. - Add new mode character 'e' to fopen(3) and popen(3) to open pipes and file descriptors for close on exec. - Add new kqueue1(2) syscall with a new flags argument to open the kqueue file descriptor with O_CLOEXEC, O_NONBLOCK. * Fix the system calls that take socklen_t arguments to actually do so. * Don't include userland header files (signal.h) from system header files (rump_syscallargs.h). * Bump libc version for the new syscalls.
1.30	14-Nov-2010	tron	Improve and simplify implementation of env(3) functions: - Use RB tree to keep track of memory allocated via setenv(3) as suggested by Enami Tsugutomo in private e-mail. This simplifies the code a lot as we no longer need to keep the size of "environ" in sync with an array of allocated environment variables. It also makes it possible to free environment variables in unsetenv(3) if something has changed the order of the "environ" array. - Fix a bug in getenv(3) and getenv_r(3) which would return bogus results e.g. for " getenv("A=B") " if an environment variable "A" with value "B=C" exists. - Clean up the internal functions: - Don't expose the read/write lock for the environment to other parts of "libc". Provide locking functions instead. - Use "bool" to report success or failure. - Use "ssize_t" or "size_t" instead of "int" for indexes. - Provide internal functions with simpler interfaces e.g. don't combine return values and reference arguments. - Don't copy "environ" into an allocated block unless we really need to grow it. Code reviewed by Joerg Sonnenberger and Christos Zoulas, tested by Joerg Sonnenberger and me. These changes also fix problems in zsh 4.3. and pam_ssh according to Joerg.
1.29	15-Oct-2006	christos	instead of using the (void)&foo kludge to avoid longjmp clobbering of variables make the variables volatile as needed.
1.28	15-Sep-2003	cl	make popen/pclose thread safe
1.27	07-Aug-2003	agc	Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22280, verified by myself.
1.26	04-Mar-2003	nathanw	Don't acquire __environ_lock around exec() calls; nothing requires that these calls be thread-safe with respect to the environment, and it causes serious problems for threaded applications which call vfork() and exec() (including indirectly, via popen() or system()). Acquire and release __environ_lock in the parent in popen() and system() to play safe and provide the child with a stable environment. __environ_lock should also have an atfork() handler; still under development.
1.25	22-Jan-2000	mycroft	Delint. Remove trailing ; from uses of __weak_alias(). The macro inserts this if needed.
1.24	20-Sep-1999	lukem	back out the #ifdef _DIAGNOSTIC argument checks; too many people complained. _DIAGASSERT() is still retained.
1.23	16-Sep-1999	lukem	* use _DIAGASSERT() to check pointer arguments against NULL and file descriptors against -1 (as appropriate). * add actual checks which to detect stuff that would trigger_DIAGASSERT(), and attempt to return a sane error condition. * knf some code * remove some `register' decls. the first two items result in the addition of code similar to the following in various functions: _DIAGASSERT(path != NULL) #ifdef _DIAGNOSTIC if (path == NULL) { errno = EFAULT; return (-1); } #endif
1.22	18-Jul-1998	lukem	use AF_LOCAL instead of AF_UNIX
1.21	19-Mar-1998	tv	PR 3673: possible to close the wrong fds

1.15	16-Sep-1997	thorpej	Make this safe in environments that have a Real vfork(2). Bug pointed out by Chuck Cranor <chuck@netbsd.org>
1.14	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.
1.13	13-Jul-1997	christos	Fix clobbered variable warning Fix RCSID's

"Some historical implementations either block or ignore the signals SIGINT, SIGQUIT, and SIGHUP while waiting for the child process to terminate. Since this behavior is not described in POSIX.2, such implementations are not conforming."

This change eliminates usage of the global changes of the following symbols: - strlcat -> _strlcat - sysconf -> __sysconf - closedir -> _closedir - fparseln -> _fparseln - kill -> _kill - mkstemp -> _mkstemp - reallocarr -> _reallocarr - strcasecmp -> _strcasecmp - strncasecmp -> _strncasecmp - strptime -> _strptime - strtok_r -> _strtok_r - sysctl -> _sysctl - dlopen -> __dlopen - dlclose -> __dlclose - dlsym -> __dlsym Sponsored by <The NetBSD Foundation>

1.11	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

1.28	06-May-2025	riastradh	libc: Sprinkle #ifdef _REENTRANT around thr_sigsetmask. Workaround -- temporary, I hope -- for: PR lib/59401: libc: thr_sigsetmask definition is incoherent
1.27	09-Apr-2025	kre	Redo pthread_atfork to avoid malloc() Allow as many calls to pthread_atfork() as are needed, without ever doing a single malloc() so it can be called as much as needed in constructors, etc. This is the implementation mooted some weeks ago - there were some alternative suggestions for a different solution, but none of them have eventuated, so until something else happens, this will do. I have been running with this for a while now, no issues observed, though I am not much of a user of threaded applications, or anything that really needs constructors. Feel free to revert (or fix) this if something breaks.
1.26	04-Mar-2025	christos	Explain the situation better and allocate 16 instead of 3 for now to cover the known cases (from kre@). Still needs to be fixed properly.
1.25	04-Mar-2025	riastradh	Revert __libc_atfork addition. This reverts the following revisions: lib/libc/gen/arc4random.c 1.40-41 (but not 1.42 which is independent) lib/libc/gen/pthread_atfork.c 1.24 lib/libc/include/atfork.h 1.1 This additionally updates the comments in arc4random.c to reflect the current state. Requested by kre: https://mail-index.netbsd.org/source-changes-d/2025/03/03/msg014388.html Since the new symbol __libc_atfork has not been used outside libc, this poses no ABI compatibility issues.
1.24	02-Mar-2025	riastradh	libc: New __libc_atfork. This uses caller-provided storage for the callback queues. Use it in arc4random(3) in order to avoid possible failure modes. This is a private symbol, not designed for use outside NetBSD, and the API is not intended to be stable (yet) -- I just took the existing purely internal structure (struct atfork_callback) and reused it for this API without changing any of the calling-side logic. We could change it, e.g. to use a single structure per call, to make the API a little less unwieldy, at the cost of microscopically more storage and runtime for the users that don't use all three callbacks; to be considered in a future change. We might reasonably use __libc_atfork in libpthread for use in the pthread_tsd_init constructor, in order to be confident it never attempts malloc(3), but let's do that in a separate commit just in case anything goes awry with that plan. PR lib/59112: libpthread constructors use malloc PR lib/59117: arc4random has some failure modes it shouldn't
1.23	01-Mar-2025	christos	simplify af_free() (from kre@)
1.22	01-Mar-2025	christos	keep a cache of 3 entries so that we don't have to call malloc(3) from libpthread which can't call malloc from a constructor.
1.21	01-Mar-2025	christos	Revert for now. There has been a report that arc4random breaks with it, and the tests for arc4random set RLIMIT_AS to 0 so that mmap fails.
1.20	28-Feb-2025	kre	Specify MAP_ANON, the default (MAP_FILE) with a fd == -1 makes no sense.

1.17	13-Sep-2022	riastradh	pthread_atfork(3): Block signals during the call to pthread_atfork. This doesn't affect the calls to the atfork handlers -- it only protects access to the lists of handlers from interruption by a signal, in case the signal handler calls fork(2).
1.16	31-May-2022	andvar	fix various typos in comments, documentation and messages.
1.15	15-May-2020	joerg	Hook up proper fork lock handling for malloc: - lock all relevant mutexes just before fork - unlock all mutexes just after fork in the parent - full reinit non-spinlocks in the child This is not using the normal pthread_atfork interface to ensure order of operation, malloc is used as implementation detail too often.
1.14	19-Apr-2020	joerg	Rename __atomic_fork to __locked_fork and give it &errno as argument. rtld and libc use different storage, so the initial version would incorrectly report the failure reason for fork(). There is still a small race condition inside ld.elf_so as it doesn't use thread-safe errno internally, but that's a more contained internal issue.
1.13	16-Apr-2020	joerg	Introduce intermediate locking for fork, so that the dynamic linker is in a consistent state. This most importantly avoids races between dlopen and friends and fork, potentially resulting in dead locks in the child when it itself tries to acquire locks.
1.12	01-Feb-2020	kamil	Revert previous 'git grep' breaks now.
1.11	01-Feb-2020	kamil	Switch atform allocations from malloc()+free() to mmap()+munmap() This avoid bootstrapping malloc too early when libc+libpthread are not ready. It is called through pthread__init() -> _pthread_atfork(). This also helps LLVM Leak Sanitizer to pacify false positive reports.

These changes should make it easier to "tool-ify" a program by adding: #if HAVE_NBTOOL_CONFIG_H #include "nbtool_config.h" #endif to the top of the source files (for the general case).

1.8	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

1.25.2.1	22-Jun-2004	tron	Pull up revision 1.29 (requested by jmc in ticket #527): Completely rework how tools/compat is done. Purge all uses/references to _NETBSD_SOURCE as this makes cross building from older/newer versions of NetBSD harder, not easier (and also makes the resulting tools 'different') Wrap all required code with the inclusion of nbtool_config.h, attempt to only use POSIX code in all places (or when reasonable test w. configure and provide definitions: ala u_int, etc). Reviewed by lukem. Tested on FreeBSD 4.9, Redhat Linux ES3, NetBSD 1.6.2 x86 NetBSD current (x86 and amd64) and Solaris 9. Fixes PR's: PR#17762 PR#25944

1.7	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

1.17	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

Otherwise, we're forced to have to have two copies of the error message string table in the library. Fortunately, unless a program uses both sys_errlist[] and strerror(), only one of the copies will be linked into the executable. This is all to provide an clean namespace as required by ANSI. I've done the same for sys_siglist[], even though it is not required, to be consistant.

As usual a leading "sig" is ignored and the strings are case independent. Some implementations do not name the real time signals, and using labels like RTMIN+3 can be the only way they can be manipulated, so allow that technique (we still return the RTnn names on the inverse translation though). Because this is used by both kill(1) and sh(1) the kill and trap commands both gain access to the new notation (when !SMALL).

1.3	20-Aug-2020	kre	When not compiling -DSMALL permit use of names RTMIN[+n] and RTMAX[-n] (where n is a decimal integer in the range [0 .. SIGRTMAX-SIGRTMIN]. As usual a leading "sig" is ignored and the strings are case independent. Some implementations do not name the real time signals, and using labels like RTMIN+3 can be the only way they can be manipulated, so allow that technique (we still return the RTnn names on the inverse translation though). Because this is used by both kill(1) and sh(1) the kill and trap commands both gain access to the new notation (when !SMALL).
1.2	04-Jan-2018	kamil	Add bunch of missing includes of namespace.h in libc The NetBSD Standard C Library uses internally some of its functions with a mangled symbol name, usually "_symbol". The internal functions shall not use the global (public) symbols. This change eliminates usage of the global changes of the following symbols: - strlcat -> _strlcat - sysconf -> __sysconf - closedir -> _closedir - fparseln -> _fparseln - kill -> _kill - mkstemp -> _mkstemp - reallocarr -> _reallocarr - strcasecmp -> _strcasecmp - strncasecmp -> _strncasecmp - strptime -> _strptime - strtok_r -> _strtok_r - sysctl -> _sysctl - dlopen -> __dlopen - dlclose -> __dlclose - dlsym -> __dlsym Sponsored by <The NetBSD Foundation>

1.19	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

1.5	29-Sep-1997	enami	Delete `: %m' from a format string passed to err().
1.4	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

Minor fixes for scheduling calls to conform the POSIX: - If pid is equal to zero, use the calling process; - In case of permission problem, return EPERM instead of EACESS; - sched_setscheduler() should return previously used policy; - pthread_* calls should return the error code or zero; Should fix the namespace problems (and builds of some packages): - Move cpuset_t defintion from pset.h to sched.h; - Remove the #include of pset.h in pthread.h;

1.16	30-Jun-2002	bjh21	Version times() so that programs compiled before the recent change to make sysconf(_SC_CLK_TCK) return hz will work. In detail: __times13() returns values scaled by hz. times() returns values scaled by 100. <sys/times.h> renames times() to __times13(). _SC_CLK_TCK has changed from 3 to 39. sysconf(3) returns 100. sysconf(39) returns hz. CLK_TCK is defined as sysconf(39).
1.15	23-Jun-2002	perry	make sysconf(_SC_CLK_TCK) return the kernel hz value, instead of a fixed constant, as is done on Solaris, Linux, etc. Technically, standards don't require this, but having it return a constant is a violation of the spirit, and screws up programs that (perhaps improperly) assume that it will return kernel hz.
1.14	31-Jan-2002	kleink	Add {POSIX_MONOTONIC_CLOCK} variables.

1.8	24-May-1998	kleink	Add support to query PAGESIZE, PAGE_SIZE, _POSIX_FSYNC and _XOPEN_SHM via sysconf().
1.7	30-Mar-1998	kleink	Need <time.h> for CLK_TCK definition.
1.6	27-Feb-1998	perry	trivial changes to quiet lint.
1.5	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

Whenever certain conditions happen in the TCP stack, this interface calls the specified callback to handle the situation according to the currently selected congestion control algorithm. A new sysctl node was created: net.inet.tcp.congctl.{available,selected} with obvious meanings. The old net.inet.tcp.newreno MIB was removed. The API is discussed in tcp_congctl(9). In the near future, it will be possible to selected a congestion control algorithm on a per-socket basis. Discussed on tech-net and reviewed by <yamt>.

1.178	11-Aug-2006	christos	Pretending to be Elad's keyboard: fileassoc.diff adds a fileassoc_table_run() routine that allows you to pass a callback to be called with every entry on a given mount. veriexec.diff adds some raw device access policies: if raw disk is opened at strict level 1, all fingerprints on this disk will be invalidated as a safety measure. level 2 will not allow opening disk for raw writing if we monitor it, and prevent raw writes to memory. level 3 will not allow opening any disk for raw writing. both update all relevant documentation. veriexec concept is okay blymn@.

1.171	14-Jul-2006	elad	okay, since there was no way to divide this to two commits, here it goes.. introduce fileassoc(9), a kernel interface for associating meta-data with files using in-kernel memory. this is very similar to what we had in veriexec till now, only abstracted so it can be used more easily by more consumers. this also prompted the redesign of the interface, making it work on vnodes and mounts and not directly on devices and inodes. internally, we still use file-id but that's gonna change soon... the interface will remain consistent. as a result, veriexec went under some heavy changes to conform to the new interface. since we no longer use device numbers to identify file-systems, the veriexec sysctl stuff changed too: kern.veriexec.count.dev_N is now kern.veriexec.tableN.* where 'N' is NOT the device number but rather a way to distinguish several mounts. also worth noting is the plugging of unmount/delete operations wrt/fileassoc and veriexec. tons of input from yamt@, wrstuden@, martin@, and christos@.
1.170	16-May-2006	elad	Introduce PaX MPROTECT -- mprotect(2) restrictions used to strengthen W^X mappings. Disabled by default.

1.152	20-Jun-2005	elad	- Use more calls to veriexec_report() where possible. - Change #ifdef VERIFIED_EXEC_VERBOSE to another verbose level, 2. Add sysctl(3) bits. - Simplify access type conflict handling during load. This depends on the values of access type defines to be ordered from least to most 'strict'.
1.151	17-Jun-2005	wiz	New sentence, new line.
1.150	17-Jun-2005	elad	More veriexec changes: - Better organize strict level. Now we have 4 levels: - Level 0, learning mode: Warnings only about anything that might've resulted in 'access denied' or similar in a higher strict level. - Level 1, IDS mode: - Deny access on fingerprint mismatch. - Deny modification of veriexec tables. - Level 2, IPS mode: - All implications of strict level 1. - Deny write access to monitored files. - Prevent removal of monitored files. - Enforce access type - 'direct', 'indirect', or 'file'. - Level 3, lockdown mode: - All implications of strict level 2. - Prevent creation of new files. - Deny access to non-monitored files. - Update sysctl(3) man-page with above. (date bumped too :) - Remove FINGERPRINT_INDIRECT from possible fp_status values; it's no longer needed. - Simplify veriexec_removechk() in light of new strict level policies. - Eliminate use of 'securelevel'; veriexec now behaves according to its strict level only.

1.148	24-May-2005	elad	Add man-page bits about the 'count' node.
1.147	19-May-2005	elad	Some changes in veriexec. New features: - Add a veriexec_report() routine to make most reporting consistent and remove some common code. - Add 'strict' mode that controls how veriexec behaves. - Add sysctl knobs: o kern.veriexec.verbose controls verbosity levels. Value: 0, 1. o kern.veriexec.strict controls strict level. Values: 0, 1, 2. See documentation in sysctl(3) for details. o kern.veriexec.algorithms returns a string with a space separated list of supported hashing algorithms in veriexec. - Updated documentation in man pages for sysctl(3) and sysctl(8). Bug fixes: - veriexec_removechk(): Code cleanup + handle FINGERPRINT_NOTEVAL correctly. - exec_script(): Don't pass 0 as flag when executing a script; use the defined VERIEXEC_INDIRECT - which is 1. Makes indirect execution enforcement work. - Fix some printing formats and types..

These are of use to userland code which previously depended on the hard-coded values of LABELSECTOR and LABELOFFSET to figure out the location of the disklabel for a particular platform. With the introduction of umbrella ports such as evbarm, evbmips, etc, the location of the disklabel may vary between kernels for the same MACHINE.

There is a "-offset indent" combination that makes sense, and you can certainly say "-width indent". * Also, you can't markup the -width option argument, tho you CAN use a callable macro. So "-width Ar filename" doesn't make sense, but either "-width Ar" or "-width filename" does, as might something like "-width xxfilename" for a little extra space. * There are a lot of needlessly complex hanging tag macros in man4 used to create simple item lists. Those should be simplified one of these days before someone copies and edits yet another man4 page.

1.73	07-Feb-2001	itojun	during ip6/icmp6 inbound packet processing, do not call log() nor printf() in normal operation (/var can get filled up by flodding bogus packets). sysctl net.inet6.icmp6.nd6_debug will turn on diagnostic messages. (#define ND6_DEBUG will turn it on by default) improve stats in ND6 code. lots of synchronziation with kame (including comments and cometic ones).

1.68	26-Aug-2000	itojun	implement net.inet6.ip6.{anon,low}port{min,max} sysctl variable.
1.67	26-Aug-2000	itojun	document net.inet.ip.lowport{min,max}
1.66	04-Aug-2000	kml	Correct the documentation for SACK; although we have some preliminary code in the tree, it doesn't do anything, and setting the sack sysctl won't have any effect.
1.65	02-Aug-2000	itojun	pps rate limitation can be turned off by negative value.

1.53	29-Mar-2000	jdolecek	kill reference to getvfsbyname(3) - it's no longer present on NetBSD
1.52	27-Feb-2000	itojun	add hw.alignbytes sysctl mib. this gives you the value of ALIGNBYTES at the kernel compilation time (ALIGNBYTES that the kernel uses).
1.51	26-Feb-2000	itojun	remove net.inet6.ip6.nd6_proxyall sysctl. support "ndp -s <ip6> <mac> proxy" for proxy NDP.

1.46	06-Jan-2000	itojun	make IPV6_BINDV6ONLY setsockopt available. it controls behavior of AF_INET6 wildcard listening socket. heavily documented in ip6(4). net.inet6.ip6.bindv6only defines default value. default is 1. "options INET6_BINDV6ONLY" removes any code fragment that supports IPV6_BINDV6ONLY == 0 case (not defopt'ed as use of this is rare).
1.45	06-Jan-2000	itojun	wording fix in net.inet6.icmp6.errratelim.
1.44	06-Jan-2000	itojun	add missing variables under net.inet6.ip6.
1.43	02-Jan-2000	itojun	add net.inet6.icmp6.nodeinfo sysctl. this allows you to disable/enable ICMPv6 node information query/reply processing (which tells remote end the gethostname(3) setting, interface addresses on the node, and some other things - documented in draft-ietf-ipngwg-icmp-name-lookup* or something alike). to test it, try ping6 -w ::1 with nodeinfo=0 and nodeinfo=1. (sync with kame change)
1.42	02-Jan-2000	itojun	typo fix

1.27	30-Apr-1998	thorpej	Document net.inet.ip.mtudisc and net.inet.ip.mtudisctimeout.
1.26	30-Apr-1998	thorpej	Rework some of the documentation pertaining to tcp.init_win and tcp.mss_ifmtu, in an attempt to make it a little more clear. Also, document tcp.mssdflt, tcp.sack, tcp.win_scale, tcp.timestamps, tcp.compat_42, tcp.cwm, and tcp.cwm_burstsize.
1.25	28-Apr-1998	fair	Fix mdoc .Xr reference for syntax or correctness (e.g. exec(2) versus exec(3)). Make other mdoc corrections as inspection dictated.
1.24	13-Apr-1998	kml	Fix to ensure that the correct MSS is advertised for loopback TCP connections by using the MTU of the interface. Also added a knob, mss_ifmtu, to force all connections to use the MTU of the interface to calculate the advertised MSS.

1.142.2.6	02-Jul-2005	tron	Pull up revision 1.152 (requested by elad in ticket #487): - Use more calls to veriexec_report() where possible. - Change #ifdef VERIFIED_EXEC_VERBOSE to another verbose level, 2. Add sysctl(3) bits. - Simplify access type conflict handling during load. This depends on the values of access type defines to be ordered from least to most 'strict'.
1.142.2.5	02-Jul-2005	tron	Pull up revision 1.151 (requested by elad in ticket #487): New sentence, new line.
1.142.2.4	02-Jul-2005	tron	Pull up revision 1.150 (requested by elad in ticket #487): More veriexec changes: - Better organize strict level. Now we have 4 levels: - Level 0, learning mode: Warnings only about anything that might've resulted in 'access denied' or similar in a higher strict level. - Level 1, IDS mode: - Deny access on fingerprint mismatch. - Deny modification of veriexec tables. - Level 2, IPS mode: - All implications of strict level 1. - Deny write access to monitored files. - Prevent removal of monitored files. - Enforce access type - 'direct', 'indirect', or 'file'. - Level 3, lockdown mode: - All implications of strict level 2. - Prevent creation of new files. - Deny access to non-monitored files. - Update sysctl(3) man-page with above. (date bumped too :) - Remove FINGERPRINT_INDIRECT from possible fp_status values; it's no longer needed. - Simplify veriexec_removechk() in light of new strict level policies. - Eliminate use of 'securelevel'; veriexec now behaves according to its strict level only.

1.142.2.1	10-Jun-2005	tron	Pull up revision 1.147 (requested by elad in ticket #389): Some changes in veriexec. New features: - Add a veriexec_report() routine to make most reporting consistent and remove some common code. - Add 'strict' mode that controls how veriexec behaves. - Add sysctl knobs: o kern.veriexec.verbose controls verbosity levels. Value: 0, 1. o kern.veriexec.strict controls strict level. Values: 0, 1, 2. See documentation in sysctl(3) for details. o kern.veriexec.algorithms returns a string with a space separated list of supported hashing algorithms in veriexec. - Updated documentation in man pages for sysctl(3) and sysctl(8). Bug fixes: - veriexec_removechk(): Code cleanup + handle FINGERPRINT_NOTEVAL correctly. - exec_script(): Don't pass 0 as flag when executing a script; use the defined VERIEXEC_INDIRECT - which is 1. Makes indirect execution enforcement work. - Fix some printing formats and types..

1.26	25-Apr-2004	atatat	Remove dynamic sysctl node version 0 from the tree. It seemed okay at first, but quickly showed its shortcomings. The version 1 node we're now using should be good for a while.

1.19	24-Mar-2004	atatat	New node version and layout. This should take care of the netbsd32 emulation problem, formalizes the versioning (should it ever be needed again), and provides a slot for descriptions.

1.8	18-Nov-1998	kleink	Now that it's delinted, make it compile on LP64 platforms again. (Using a size_t for namelen isn't strictly appropriate/necessary anyhow.)
1.7	13-Nov-1998	christos	delint
1.6	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

1.31	22-Mar-2017	roy	openlog(3): add LOG_PTRIM and LOG_NLOG log options. syslog(3) is the one stop method of logging system events and diagnostics. When debugging a daemon in the foreground on a terminal, each line is prefixed with tag[pid]: which is very repetative and can take up valuable screen estate. LOG_PTRIM solves this by removing this prefix from stderr output. There is also the case where the debugging could involve a dry-run and syslog(3) calls would pollute the system log with incorrect data. LOG_NLOG solves this by not writing the the system log, but allowing LOG_PERROR to operate as before. Initially discussed here: https://mail-index.netbsd.org/tech-userlevel/2016/10/06/msg010330.html

1.58	12-Jan-2017	christos	undo SSP damage from -Wsystem-headers
1.57	12-Jan-2017	christos	A little more restructuring so that we don't need mutex stuff in syslog_ss.
1.56	12-Jan-2017	christos	Split syslog.c to: - syslog_ss.c _ss api functions (don't use stdio, time) - syslog.c: syslog* non _ss api functions (use stdio, time) - xsyslog.c> common guts. The motivation for this is not to drag in stdio/locale/floating point/time for every binary, since syslog_ss() is used in __stack_check_fail() for SSP.
1.55	26-Oct-2015	roy	branches: 1.55.2; Use strerror(3) instead of strerror_r(3) and an arbitary buffer size which could be too small.
1.54	18-Sep-2014	christos	make more descriptors that we open as close-on-exec
1.53	11-Oct-2012	christos	take care of the signal safe syslog calls which are not exposed.
1.52	10-Oct-2012	christos	add more locking (when we read and write fields)
1.51	10-Oct-2012	christos	PR/47055: David Holland: Remove static hostname and store the hostname in syslog_data. Initialize hostname before it is used. While here, add a version to syslog_data.
1.50	13-Mar-2012	christos	branches: 1.50.2; PR/45989: Martin Husemann: lint invocation does include -w only on i386 - turn lint -w for all the platforms after fixing the lint warnings. - add _DIAGASSERTS() for casts that would assign values to types that would not fit. - change types, add casts - change into ansii prototypes - turn on _DIAGNOSTIC for libc (during current, to be eliminated for release builds) approved by core@
1.49	15-Oct-2011	christos	branches: 1.49.2; close on exec fixes: - open + fcntl -> open O_CLOEXEC - configuration database file descriptors that can stay open are now opened fopen(db, "re")
1.48	13-May-2010	christos	PR/43300: Takahiro Kambe: LOG_PID and LOG_CONSOLE printed syslogp messages to the console/stderr since the syslogp conversion.
1.47	11-Jan-2009	christos	merge christos-time_t
1.46	10-Dec-2008	christos	Martin says: I had added a getaddrinfo()/getnameinfo() lookup to obtain an FQDN even if gethostname() would return only the local part of the hostname. I did not really consider that many systems do not have FQDNs and more importantly that the calls introduce a high latency (timeout) when DNS is not available. On the other hand I do not (or no longer) think that using a non-FQDN is such a big problem here. Those users/admins that do collect logs from different hosts and want an FQDN should notice the problem quickly enough and can easily fix it by correctly setting their hostname.
1.45	03-Nov-2008	cube	branches: 1.45.2; Invert the test for the return value of getaddrinfo(), because that's what is actually meant there, to do nothing when the name doesn't resolve to an address.
1.44	31-Oct-2008	christos	fix compile error.
1.43	31-Oct-2008	christos	Import syslogd SoC project by Martin Schuette: - new syslog protocol api syslogp(3) that supports structured data and draft-rfc timestamps - reliable tcp connections with queueing - encrypted connections
1.42	22-Oct-2008	dogcow	appease lint: warning: assignment in conditional context [159]
1.41	21-Oct-2008	christos	- vsyslog_r only closes if it opened - maintain opened properly - preserve the tag (from OpenBSD)
1.40	12-Jun-2008	christos	PR/38539: Ed Ravin: libc/gen/syslog.c always logs to console if LOG_CONS is set. While here: 1. Don't loop forever, handle closing and opening the log after each send. 2. Release the lock later, after we've possibly printed to the console.
1.39	22-Nov-2006	christos	branches: 1.39.16; 1.39.18; Don't expose _ss functions for 4.0. Requested by core.
1.38	05-Nov-2006	christos	weak for syslog_ss
1.37	03-Nov-2006	christos	use FD_CLOEXEC instead of 1.
1.36	02-Nov-2006	christos	- verify that the log file is usable, otherwise re-open it. - if the file is re-opened, clear the connected flag. - don't check that the file is opened before connecting, because the file will be opened then.
1.35	27-Oct-2006	christos	need to negate before masking; from abp.
1.34	27-Oct-2006	christos	add async-signal-safe versions: syslog_ss and vsyslog_ss multithread-safe syslog_r and vsyslog_r are not async-signal-safe.
1.33	26-Oct-2006	christos	don't use strerror_r in the re-entrant case.
1.32	25-Oct-2006	christos	add _r functions for syslog from OpenBSD
1.31	29-Nov-2005	christos	WARNS=4
1.30	07-Aug-2003	agc	Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22280, verified by myself.
1.29	18-Jan-2003	thorpej	Merge the nathanw_sa branch.
1.28	26-May-2002	wiz	__STDC__ is always defined on NetBSD.
1.27	30-Jul-2001	atatat	Build a single retry into syslog() so that if someone restarted syslogd after we called openlog(), we don't just to lose until we call openlog() again. Or get restarted. This is good for long running processes that use syslog(), like sendmail, postfix, named, etc.
1.26	19-Feb-2001	cgd	branches: 1.26.2; convert from __progname to getprogname()
1.25	30-Dec-2000	martin	Be consistent with argument types vs. prototype; use _BSD_VA_LIST_ as the argument, instead of va_list. Might not make a difference on most ports, depending on toolchain/MD typedefs. Does make a difference on sparc64, where it wouldn't compile otherwise.
1.24	22-Jan-2000	mycroft	branches: 1.24.4; Delint. Remove trailing ; from uses of __weak_alias(). The macro inserts this if needed.
1.23	03-May-1999	christos	Fix unaligned access lint warning.
1.22	16-Mar-1999	is	Use SUN_LEN, not sizeof.

1.20	04-Feb-1999	kleink	Protect syslog descriptor state with a mutex. TODO: cleanup handling for cancellation points.
1.19	13-Nov-1998	christos	delint
1.18	13-Sep-1998	kleink	Use localtime_r() rather than localtime(); removes a potential source of surprise for the application.
1.17	18-Aug-1998	thorpej	Add some braces to make egcs happy.
1.16	27-Jul-1998	mycroft	Delint (partially).
1.15	18-Jul-1998	lukem	use AF_LOCAL instead of AF_UNIX
1.14	03-Feb-1998	perry	remove obsolete register declarations
1.13	02-Feb-1998	perry	merge/update to lite-2
1.12	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

Since the character table is allocated via malloc(), it _may_ happen that it starts at a page boundary, so that negative values for the argument result in a segmentation fault. In that case, there is no result at all.

1.18	15-Sep-2025	riastradh	ctype(3): New environment variable LIBC_ALLOWCTYPEABUSE. If set, this does not force the ctype(3) functions to crash when passed invalid inputs -- instead, they will return nonsense results, and possibly print warnings to stderr, as is their right in implementing undefined behaviour. The nature of the nonsense results is unspecified. Currently, is*() will always return true (even if that leads to mutually contradictory conclusions, like isalpha and isdigit, or isgraph and isblank), and tolower/toupper() will always return EOF. But perhaps in the future the results may be randomized. This way, if an application like firefox crashes on ctype abuse, you can opt to accept the consequences of nonsense results instead by running `env LIBC_ALLOWCTYPEABUSE= firefox' until the application is fixed.

1.16	29-Mar-2025	riastradh	libc: Restore ELF symbol sizes for _C_ctype_tab_ &c. This is needed for dynamic position-dependent executables that refer directly to _C_type_tab_ to get correct copy relocations to see the table content. Unfortunately, such executables won't get a guard page. Fortunately, referring to _C_ctype_tab_ directly (and not the indirection _ctype_tab_ as the ctype(3) macros do) is very weird and unlikely to happen in the real world (none of the public interfaces use it; it is exported for libc++.so/libstdc++.so to use, but those aren't pies). So missing the guard page in this case is probably not so bad. The symbol sizes are also needed for, e.g., gdb to nicely identify addresses that lie in the table.

1.15	29-Mar-2025	riastradh	ctype(3): Put guard pages before the C ctype/tolower/toupper tables. This also only affects machines where char is signed for now.

This can save up to 514 bytes. In toupper_.c and tolower_.c make sure that our assumption of EOF == -1 holds. Fixed bug where _toupper_tab_ was initialized pointing to _C_tolower_tab.

1.16	18-Jan-2007	rillig	Added a reference to ctype.3. What's the value of having that page at all if it isn't referenced by others? Suggested by Slava Semushin via private mail.
1.15	05-Oct-2006	rillig	Fixed the wording of the <ctype.h> character classification functions by always using "function" instead of "macro". Changed "undefined result" into "undefined behavior" for argument values outside the valid range. Since the character table is allocated via malloc(), it _may_ happen that it starts at a page boundary, so that negative values for the argument result in a segmentation fault. In that case, there is no result at all.

1.16	29-Mar-2025	riastradh	libc: Restore ELF symbol sizes for _C_ctype_tab_ &c. This is needed for dynamic position-dependent executables that refer directly to _C_type_tab_ to get correct copy relocations to see the table content. Unfortunately, such executables won't get a guard page. Fortunately, referring to _C_ctype_tab_ directly (and not the indirection _ctype_tab_ as the ctype(3) macros do) is very weird and unlikely to happen in the real world (none of the public interfaces use it; it is exported for libc++.so/libstdc++.so to use, but those aren't pies). So missing the guard page in this case is probably not so bad. The symbol sizes are also needed for, e.g., gdb to nicely identify addresses that lie in the table.

This can save up to 514 bytes. In toupper_.c and tolower_.c make sure that our assumption of EOF == -1 holds. Fixed bug where _toupper_tab_ was initialized pointing to _C_tolower_tab.

1.1 Fixes PR lib/39662, shortcomings in LC_{MONETARY,NUMERIC,TIME,MESSAGES} db format. ok'ed by core and releng. (thanks for agc@, snj@ and i'm sorry for long time patience). [libc] - localeio.[ch] and lc.[ch] in src/lib/libc/locale was replaced by new locale-db implementation using citrus_db backend, see src/lib/libc/citrus/citrus_lc_.[ch]. - add citrus_bcs_strtou?l.c. don't use strtou?l locale implementation internally, because they're locale-aware function. - add some stubs for multi-locale issue, see {current,global}_locale.c. - remove some obsolete file, setrunelocale.c, ___runetype_mb.c. - remove __savectype() from ctypeio.[ch]. [tools] - mklocale(1): add new option ``-t'' that generates new style LC_{MONETARY,NUMERIC,TIME,MESSAGES} locale-db format. - chrtbl(1): added ctypeio.[ch] for __savectype(). [locale-db] - added en_US.US-ASCII locale. - removed some shareable locale definition file: en_US.US-ASCII -> en_US.ISO8859-1, en_US.UTF-8 zh_CN.eucCN -> zh_CN.GB18030 and more...see src/share/locale//Makefile. - remove obsoleted locale sr_YU, added new locale sr_ME, sr_RS. - change locale name ja_JP.ISO2022-JP -> ja_JP.ISO-2022-JP* for X11's locale.alias file alignments. - fix regression test, wrong wcs?width(3), NAN/INF usage. i tested release-build following arch: i386, amd64, hpc{mips,arm,sh}, sparc64, vax. citrus_lc_.[ch] also can read old-plain-text style locale-db. so that backward compatibility is keeped, but lc.[ch] can't read new citrus_db'ed locale-db and localeio.c never check sanity, so forward compatibility is broken ;-< old mklocale(1) doesn't know -t option, so you have to rebuild toolchain.

If set, this does not force the ctype(3) functions to crash when passed invalid inputs -- instead, they will return nonsense results, and possibly print warnings to stderr, as is their right in implementing undefined behaviour. The nature of the nonsense results is unspecified. Currently, is*() will always return true (even if that leads to mutually contradictory conclusions, like isalpha and isdigit, or isgraph and isblank), and tolower/toupper() will always return EOF. But perhaps in the future the results may be randomized. This way, if an application like firefox crashes on ctype abuse, you can opt to accept the consequences of nonsense results instead by running `env LIBC_ALLOWCTYPEABUSE= firefox' until the application is fixed.

1.24	03-Jun-2012	joerg	Switch device database to cdb(5). Rework ttyname(3) and ttyname_r(3) to depend on new devname_r(3) as heart. Add /dev/pts magic directly to devname(3). While it can lead to returning non-existing paths, the behavior is more consistent that way. Drop caching layer in devname(3), it doesn't buy anything for the common case of having access to the database. Teach devname(3) proper fallback behavior of scanning /dev.

1.11	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

Use queue(3) Replace linear lookup with hash table, reducing runtime by 60%. Use e* from util.h. One more strdup -> estrdup. Maintain nalias and nterm on the fly. Add void for ttyslot prototype. Use memcmp in place of strncmp, since length is known to no longer than either of the arguments. Fix a number of memory leaks. Keep final loop of the cleanup in tic(1) under #ifdef __VALGRIND__ though. Add __predict_true / __predict_false definitions. Add a special seeder for cdbw_output that gives stable results. Hook up cdbw(3) for the tool build. Prototype for cdbw_stable_seeder. Provide a usable thr_once for !_REENTRANT Switch device database to cdb(5). Rework ttyname(3) and ttyname_r(3) to depend on new devname_r(3) as heart. Add /dev/pts magic directly to devname(3). While it can lead to returning non-existing paths, the behavior is more consistent that way. Drop caching layer in devname(3), it doesn't buy anything for the common case of having access to the database. Teach devname(3) proper fallback behavior of scanning /dev. Create both old-style and new-style database for now in /etc/rc.d/sysdb. Switch terminfo(3) to cdb(5). Fix typos. Make Alan Barrett happy and add (). Add cdbr(3) support to tools/compat. Bump date for previous. Relax consistency to make it possible to match valid entries. Prefix devname's buffer with /dev/ as ttyname is supposed to return the full path. Reported by Dave Huang.
1.24.6.2	25-Jun-2008	ad	ttyname_r is another of the strange functions that returns its error code instead of setting errno.
1.24.6.1	25-Jun-2008	ad	file ttyname.c was added on branch christos-time_t on 2008-06-25 11:47:30 +0000

1.13	11-Jan-2009	christos	merge christos-time_t
1.12	11-Nov-2004	christos	branches: 1.12.34; It is silly to have to enumerate all the ptys in /etc/ttys in order to get a valid ttyslot for them. Instead if and entry is not found and we are a pty, allocate the n + 1 + minor(pty) slot.
1.11	07-Aug-2003	agc	Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22280, verified by myself.

1.8	03-Feb-1998	perry	remove obsolete register declarations
1.7	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

Unlike the OpenBSD ones they return -1 or NULL if the buffer is not large enough, instead of silently truncating.

1.21	31-Jan-2002	tv	Roll in fixes to permit cross-compiling from non-NetBSD hosts. This round has been tested on Solaris/x86 and Linux hosts. * Add host tools cap_mkdb, ctags, m4, uudecode. * Protect __RCSID() and __COPYRIGHT() better. * Reduce the number of places that need to include "config.h", to keep sources closer to their "vanilla" versions. * Add more compat #defines and autoconf-checked functions.

1.10	22-Oct-1997	fvdl	New hacks to make libc work painlessly without bumping the major number: use type func(arg1s) asm("emitted_name") gcc mechanism. Suggested by Bill Sommerfeld.
1.9	20-Oct-1997	thorpej	branches: 1.9.2; Fix the shared library versioning snafu caused by the recent changes to the stat(2) family and msync(2). This uses a primitive function versioning scheme. This reverts the libc shared library major version from 13 to 12, and adds a few new interfaces to bring us to libc version 12.20. From Frank van der Linden <fvdl@NetBSD.ORG>.
1.8	16-Oct-1997	christos	change second argument of unvis from char to int
1.7	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

1.7	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

1.53	15-Feb-2013	christos	More fixes from: J.R. Oldroyd - The input loop control that I changed yesterday to: while (mbslength >= 0) { There are circumstances where this causes an extra \000 to be added at the end of some tests. This error was showing in my own tests here, but I did not notice it yesterday. (I really need to add my tests to the test suite, catching every error by eye is hard.) To fix, I've now changed the code to increment mbslength only if mbslength == 1 to start with. (Note that this check for "== 1" is why the arg to strvisx() in vis(1) must be 1, not mbilen.) - The cast sequence when manually inserting bytes after a multibyte conversion error: src = (wint_t)(u_char)mbsrc; is wrong. This is causing problems in the case when an 8859-1 input string is processed in the UTF-8 locale. It needs to be: src = (wint_t)mbsrc; Without the (u_char) all the locale mismatch combinations then work. - The code: if (mblength < len) len = mblength; needs to be there. It resets len for the single character input case after we've actually processed two input characters (c and nextc) because we incremented mbslength at the start of the loop. Without this code, single character conversions end up with a \000 or other byte appended.

1.15	25-Nov-1999	wennmach	Added new functions char * svis(char dst, int c, int flag, int nextc, const char extra); int strsvis(char dst, const char src, int flag, const char extra); int strsvisx(char dst, const char src, size_t len, int flag, const char extra); These functions correspond to vis(), strvis(), and strvisx() but have an additional argument extra, pointing to a NUL terminated list of characters. These characters will be copied encoded or backslash-escaped into dst. These functions are useful e. g. to remove the special meaning of certain characters to shells. To implement the new functions, vis underwent a major rewrite. Most functions now use a central macro, SVIS. Performance increase ~ factor 2. Reviewed by Christos.

1.8	21-Jul-1997	jtc	If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.

1.16	16-Jan-2014	christos	Add the {v,}{err,warn}c flavors, from FreeBSD.
1.15	17-Jul-2011	joerg	branches: 1.15.2; 1.15.8; Retire varargs.h support. Move machine/stdarg.h logic into MI sys/stdarg.h and expect compiler to provide proper builtins, defaulting to the GCC interface. lint still has a special fallback. Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and derive va_list as required by standards.
1.14	18-Jun-2007	ginsbach	Follow the example of other nbtool compat functions, like dirname, and don't create if it is determined that the system in question doesn't need them. This cleans up build warnings on systems with err.h (HAVE_ERR_H) for example Mac OS X 10.3.
1.13	13-Sep-2005	christos	compat core reorg.
1.12	27-Oct-2003	lukem	Overhaul how `build.sh tools' are used: * Rename "config.h" to "nbtool_config.h" and HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H. This makes in more obvious in the source when we're using tools/compat/config.h versus "standard autoconf" config.h * Consistently move the inclusion of nbtool_config.h to before <sys/cdefs.h> so that the former can provide __RCSID() (et al), and there's no need to protect those macros any more. These changes should make it easier to "tool-ify" a program by adding: #if HAVE_NBTOOL_CONFIG_H #include "nbtool_config.h" #endif to the top of the source files (for the general case).

1.4	17-Aug-1999	mycroft	Make some needed weak aliases.
1.3	17-Jul-1997	thorpej	"Fix" the non-__indr_reference verions of the user-callable versions of these functions. This is somewhat of a kludge, but there is not much else we can do for this case. Because of how the callable versions are created, by CPP trickery and inclusion of another .c file, we cannot allow the included .c file to pull in "namespace.h", since it undoes the CPP trickery we have performed.

1.14	18-Jun-2007	ginsbach	Follow the example of other nbtool compat functions, like dirname, and don't create if it is determined that the system in question doesn't need them. This cleans up build warnings on systems with err.h (HAVE_ERR_H) for example Mac OS X 10.3.
1.13	13-Sep-2005	christos	don't use the weak names directly, so that the compat code works.
1.12	13-Sep-2005	christos	compat core reorg.
1.11	16-Jul-2005	christos	Add missing _.
1.10	27-Oct-2003	lukem	Overhaul how `build.sh tools' are used: * Rename "config.h" to "nbtool_config.h" and HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H. This makes in more obvious in the source when we're using tools/compat/config.h versus "standard autoconf" config.h * Consistently move the inclusion of nbtool_config.h to before <sys/cdefs.h> so that the former can provide __RCSID() (et al), and there's no need to protect those macros any more. These changes should make it easier to "tool-ify" a program by adding: #if HAVE_NBTOOL_CONFIG_H #include "nbtool_config.h" #endif to the top of the source files (for the general case).
1.9	07-Aug-2003	agc	Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22280, verified by myself.
1.8	26-May-2002	wiz	__STDC__ is always defined on NetBSD.
1.7	31-Jan-2002	tv	Roll in fixes to permit cross-compiling from non-NetBSD hosts. This round has been tested on Solaris/x86 and Linux hosts. * Add host tools cap_mkdb, ctags, m4, uudecode. * Protect __RCSID() and __COPYRIGHT() better. * Reduce the number of places that need to include "config.h", to keep sources closer to their "vanilla" versions. * Add more compat #defines and autoconf-checked functions.
1.6	28-Jan-2002	tv	Fix previous to actually include config.h.
1.5	28-Jan-2002	tv	Make compilable from src/tools/compat.
1.4	17-Aug-1999	mycroft	branches: 1.4.10; Make some needed weak aliases.
1.3	17-Jul-1997	thorpej	"Fix" the non-__indr_reference verions of the user-callable versions of these functions. This is somewhat of a kludge, but there is not much else we can do for this case. Because of how the callable versions are created, by CPP trickery and inclusion of another .c file, we cannot allow the included .c file to pull in "namespace.h", since it undoes the CPP trickery we have performed. Introduce a CPP macro that prevents the included .c file from pulling in "namespace.h".
1.2	13-Jul-1997	christos	Use "namespace.h" Fix RCSID's
1.1	15-Apr-1996	jtc	branches: 1.1.2; Split each function in err.c out into its own file. This is needed for systems without weak or indirect references.

1.3	22-Mar-2017	roy	openlog(3): add LOG_PTRIM and LOG_NLOG log options. syslog(3) is the one stop method of logging system events and diagnostics. When debugging a daemon in the foreground on a terminal, each line is prefixed with tag[pid]: which is very repetative and can take up valuable screen estate. LOG_PTRIM solves this by removing this prefix from stderr output. There is also the case where the debugging could involve a dry-run and syslog(3) calls would pollute the system log with incorrect data. LOG_NLOG solves this by not writing the the system log, but allowing LOG_PERROR to operate as before. Initially discussed here: https://mail-index.netbsd.org/tech-userlevel/2016/10/06/msg010330.html
1.2	12-Jan-2017	christos	branches: 1.2.2; 1.2.4; A little more restructuring so that we don't need mutex stuff in syslog_ss.
1.1	12-Jan-2017	christos	Split syslog.c to: - syslog_ss.c _ss api functions (don't use stdio, time) - syslog.c: syslog* non _ss api functions (use stdio, time) - xsyslog.c> common guts. The motivation for this is not to drag in stdio/locale/floating point/time for every binary, since syslog_ss() is used in __stack_check_fail() for SSP.
