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.

Tidy up how __sigaction14_sigtramp.c is added to SRCS.

Merge all MD __sigaction14_sigtramp.c copies into one:
- sparc and sparc64 were not using version 0 sigcontext when there were
no arguments in the signal version. This was probably a bug.
- vax is using +1 the version numbers of the other archs.
- Only hppa was defining __LIBC12_SOURCE__ so it was getting a working
sigcontext before. all the other ports that supported sigcontext had
the compat code disabled.

If we want to remove sigcontext support from userland at least now there
is less work to do so.

Add native implementations of eventfd(2) and timerfd(2), compatible with

New system call getrandom() compatible with Linux and others.

Three ways to call:

getrandom(p, n, 0) Blocks at boot until full entropy.
Returns up to n bytes at p; guarantees
up to 256 bytes even if interrupted
after blocking. getrandom(0,0,0)
serves as an entropy barrier: return
only after system has full entropy.

getrandom(p, n, GRND_INSECURE) Never blocks. Guarantees up to 256
bytes even if interrupted. Equivalent
to /dev/urandom. Safe only after
successful getrandom(...,0),
getrandom(...,GRND_RANDOM), or read
from /dev/random.

getrandom(p, n, GRND_RANDOM) May block at any time. Returns up to n
bytes at p, but no guarantees about how
many -- may return as short as 1 byte.
Equivalent to /dev/random. Legacy.
Provided only for source compatibility
with Linux.

Can also use flags|GRND_NONBLOCK to fail with EWOULDBLOCK/EAGAIN
without producing any output instead of blocking.

- The combination GRND_INSECURE|GRND_NONBLOCK is the same as
GRND_INSECURE, since GRND_INSECURE never blocks anyway.

- The combinations GRND_INSECURE|GRND_RANDOM and
GRND_INSECURE|GRND_RANDOM|GRND_NONBLOCK are nonsensical and fail
with EINVAL.

As proposed on tech-userlevel, tech-crypto, tech-security, and
tech-kern, and subsequently adopted by core (minus the getentropy part
of the proposal, because other operating systems and participants in
the discussion couldn't come to an agreement about getentropy and

setcontext() used to be incompatible with -lpthread since it affected

Some ports had _UC_TLSBASE flag or equivalent (_UC_UNIQUE on alpha)

This change let libpthread override setcontext() with its own version
that unsets _UC_TLSBASE, enabling safe usage of setcontext() with
-lpthread.

We also have the following required changes here:
- rename alpha's _UC_UNIQUE into _UC_TLSBASE
- add _UC_TLSBASE definition in header file for all ports
(powerpc, sh3, sparc and sparc64 lack the implementation for now)
- introduce a libc stub that can be overriden for setcontext()
- modify MD libcs swapcontext() implementations so that they use the
setcontext() libc stub instead of doing a plain system call.

While we are there:
- document various MD _UC_* flags in header file
- add libc and libpthread tests for swapcontext() behavior
(hopefully helpful to spot MD problems introduced with this change)

Future work:
- Deciding whether kernel support or _UC_TLSBASE should be added for
powerpc, sh3, sparc and sparc64 is left to portmasters

Change all the syscall C 'glue' functions (most of which just add in an
extra argument to ensure that 'off_t' parameters are even numbered
parameters for stack alignment reasons on 32 bit systems) to use a normal
'syscall' wrapper for __foo instead of using __syscall(SYS_foo, ... ).
This saves all the faffing needed to get a 32bit return value on sparc.
Auto-generate the extra syscall wrappers.
Move swapon.c into the correct list (swapon() uses swapctl()).
This probably means there are very few users of syscall() and __syscall() left.

- stack_protector.c doesn't really belong under sys/. Add a new directory

- Add a libc constructor. Use this to initialize threading and the

MAKEVERBOSE messages

uuidgen(2) syscall. Originally from FreeBSD, ported by John Franklin in
PR#23470, with minor updates by me. This is only the syscall support
from that PR, for now.

Changes: port over fix from FreeBSD for multicast address generation.
Changed bcopy to memcpy. For now, #ifdef notyet the portions of
kern_uuid.c that are meant to be used by (currently nonexistent) other
things in the kernel. Added syscall to COMPAT_FREEBSD as well, though
that's currently not useful, as any program new enough to use this call
also uses other syscalls we don't (yet) emulate.

- libc.so.12.109 and libpthread.so.0.4
- add ssize_t stackinfo_offset argument to sa_register syscall
- remove sa_unblockyield syscall
- make __sigprocmask14 syscall weak
- in pthread__sa_start: catch up with 4-argument sa_register syscall

Userland portion of fsync_range(2), written by Bill Studenmund, and
contributed by Wasabi Systems, Inc.

fix SA/pthread pagefault failure:
- prevent BLOCKED upcalls on double page faults and during upcalls
- make libpthread handle blocked threads which hold locks

forgot to install timer_settime.

Add timer man pages. Hi Nathan!

Rework how dependency generation is performed:

* DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES.
This is a change of behaviour. If a Makefile wants the clean semantics
it must specifically append to CLEANFILES.
Resolves PR toolchain/5204.

* To recap: .d (depend) files are generated for all files in SRCS and DPSRCS
that have a suffix of: .c .m .s .S .C .cc .cpp .cxx

* If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES

* Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d depend upon ${DPSRCS}

* Deprecate the (short lived) DEPENDSRCS


Update the various Makefiles to these new semantics; generally either
adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing
specific .o dependencies with DPSRCS entries.

Tested with "make -j 8 distribution" and "make distribution".

USE ${HOST_SH}

Make execve a weak syscall.

Add _Exit(), for C99 and POSIX-2001.
Proposed on tech-userlevel to a resounding silence in April last year.

add POSIX sigtimedwait(), sigwaitinfo(), sigwait() - wait for queued signals

note these are for non-threaded programs only - libpthread will provide
it's own thread-aware wrapper

for WEAKSM list, use leading tab, rather than spaces on the continuation lines

Make the generated .S files depend on ${.CURDIR}/sys/Makefile.inc.

Move accept and connect stubs to WEAKASM so that they can be overridden.

Add _ksem stubs.

change HISTORY to clearly state this interface is only available with

Fix some problems using makelintstub as a cross-tool:

Provide the target's preprocessor when invoking makelintstub.
* Fix some quoting issues that turned up with Solaris 8's XPG4 sh and sed.
* Don't use echo -n. Instead, don't bother making the output pretty; the
whitespace isn't supposed to be syntactically significant anyhow.

rasctl(2)

Add stubs to new system calls for performance monitoring interface.

Enable the libc-provided signal trampoline. The old __sigaction14
entry point has been replaced by the new __sigaction14() which is a
wrapper around the __sigaction_sigtramp system call (which is itself
not directly exposed outside of libc).

No shared library version change is necessary; no new symbols
are exposed outside of libc.

branches: 1.124.2;
Don't even put Lint*.c in DPSRCS if MKLINT=no.

* Add WSYSCALL() to SYS.h, which creates a system call with an
internal name and a weak alias for the name.
* Add a WEAKASM syscall list, and process it.
* Make sysarch() have an internal name (_sysarch()).

Only put LintSys*.c in DPSRCS; the others are static files.

Clean up a little more (DPSRCS already goes in CLEANFILES; reduce
redundancy of DPSRCS).

No need for the .for in this case (holdover from earlier noncommitted
version of the simplification).

Make previous a bit cleaner, too: just refer to all these files by the
.S extension; no need to do all the :.o=.S transforms.

Fix backslash typo in previous.

Make the generation of syscall stubs a lot more reliable by generating real
`.S' files and letting <bsd.sys.mk> and <bsd.lib.mk> compile them like every
other .S file. The compilation options passed to ${CC} are still correct.

Also make sure LintSysPseudoNoerr.c gets removed on "make clean".

Added support to use the clockctl driver if present for adjtime(),
clock_settime(), ntp_adjtime() and settimeofday(). The super-user still
always use the plain system call.

script (sys/makelintstub) and pipe the result to lint. Unfortunately,
dependency handling for these built .ln files is a bit sub-optimal right
now, but that can be fixed later.

Add clock_* and ntp_* syscalls

Treat reboot() like a normal system call. From PR 2458.

Remove spurious clock_* syscalls that got committed last night. They
broke shared libc's very badly. (Okayed by thorpej).

Generate syscall functions which can never fail (getgid, getegid, geteuid,
getpid, getppid, ...) with new RSYSCALL_NOERROR macro which has been added
to the SYS.h header of each port.

temporary hack until better support for multiple toolchains is in the tree:
build SASM and SPSEUDO on the alpha without the '-k' flag to the assembler,
since -k is a flag specific to NetBSD's hacked assembler.

Renamed _getlogin syscall to __getlogin, as _getlogin is the namespace
clean name for getlogin.

- sparc and sparc64 were not using version 0 sigcontext when there were
no arguments in the signal version. This was probably a bug.
- vax is using +1 the version numbers of the other archs.
- Only hppa was defining __LIBC12_SOURCE__ so it was getting a working

- 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.

oops, do not write the same file twice -- accidentally ran patch twice

Add accept4, a tiny wrapper around paccept.

accept4 is a syscall in Linux, FreeBSD and OpenBSD. It is used in
LLVM, zeromq, and probably others. paccept is a superset of it.

adding it to libc ensures it is used by programs and prevents the
need to define the same wrapper in every program.

Add missing word.

branches: 1.32.12;
Revert defective O_SEARCH implementation committed by manu@ along with
the *at system calls on November 18th of last year. Reasons to revert
it include:
- it is incorrect in a whole variety of ways (but fortunately, one
of them is that the missing and improper permission checks have
no net effect);
- it was committed without review or discussion;
- core ruled that all the new O_* flags pertaining to the *at calls
needed to wait until their semantics could be clarified.

manu was asked to revert it on these grounds but has ignored the request.

I have left O_SEARCH defined and visible and made open() explicitly
ignore it. This way, most code that tries to use it will continue to
build and run. I've also arranged lib/libc/c063/t_o_search.c so that
the tests that make use of the O_SEARCH semantics will disappear until
O_SEARCH comes back, and fixed some mistakes and/or incorrect hacks
that were causing some of these to succeed despite the broken O_SEARCH
implementation.

One more bit: explicitly state what calls to faccessat() are equivalent
to access().

Rewrite heavily. This was originally going to be just an improvement of
some wording related to the *at form... but it needed a general overhaul.

Add some missing errors for the *at form... plus EINVAL for the
traditional form for when you pass a bogus check mode.

Note that the AT_EACCESS flag is useless and strengthen the security
warning.

New sentence, new line. Add articles.
