1.12	10-Jun-2018	christos	use SUBDIR.roff suggested by uwe@
1.11	05-Jul-2014	dholland	branches: 1.11.22; Rework /usr/share/doc. Update the <bsd.doc.mk> infrastructure, and update the docs to match the new infrastructure. - Build and install text, ps, pdf, and/or html, not roff sources. - Don't wire the chapter numbers into the build system, or use them in the installed pathnames. This didn't matter much when the docs were a museum, but now that we're theoretically going to start maintaining them again, we're going to add and remove documents periodically and having the chapter numbers baked in creates a lot of thrashing for no purpose. - Specify the document name explicitly, rather than implicitly in a path. Use this name (instead of other random strings) as the name of the installed files. - Specify the document section, which is the subdirectory of /usr/share/doc to install into. - Allow multiple subdocuments. (That is, multiple documents in one output directory.) - Enumerate the .png files groff emits along with html so they can be installed. - Remove assorted hand-rolled rules for running roff and roff widgetry and add enough variable settings to make these unnecessary. This includes support for - explicit use of soelim - refer - tbl - pic - eqn - Forcibly apply at least minimal amounts of sanity to certain autogenerated roff files. - Don't exclude USD.doc, SMM.doc, and PSD.doc directories from the build, as they now actually do stuff. Note: currently we can't generate pdf. This turns out to be a nontrivial problem with no immediate solution forthcoming. So for now, as a workaround, install compressed .ps as the printable form.

1.11.22.1	25-Jun-2018	pgoyette	Sync with HEAD
1.8	22-Apr-2009	lukem	Enable WARNS=4 by default, except for: cpuctl dumplfs hprop ipf iprop-log kadmin kcm kdc kdigest kimpersonate kstash ktutil makefs ndbootd ntp pppd quot racoon racoonctl rtadvd sntp sup tcpdchk tcpdmatch tcpdump traceroute traceroute6 user veriexecgen wsmoused zic (Mostly third-party applications)
1.7	28-May-2007	tls	branches: 1.7.20; Add new Makefile knob, USE_FORT, which extends USE_SSP by turning on the FORTIFY_SOURCE feature of libssp, thus checking the size of arguments to various string and memory copy and set functions (as well as a few system calls and other miscellany) where known at function entry. RedHat has evidently built all "core system packages" with this option for some time. This option should be used at the top of Makefiles (or Makefile.inc where this is used for subdirectories) but after any setting of LIB. This is only useful for userland code, and cannot be used in libc or in any code which includes the libc internals, because it overrides certain libc functions with macros. Some effort has been made to make USE_FORT=yes work correctly for a full-system build by having the bsd.sys.mk logic disable the feature where it should not be used (libc, libssp iteself, the kernel) but no attempt has been made to build the entire system with USE_FORT and doing so will doubtless expose numerous bugs and misfeatures. Adjust the system build so that all programs and libraries that are setuid, directly handle network data (including serial comm data), perform authentication, or appear likely to have (or have a history of having) data-driven bugs (e.g. file(1)) are built with USE_FORT=yes by default, with the exception of libc, which cannot use USE_FORT and thus uses only USE_SSP by default. Tested on i386 with no ill results; USE_FORT=no per-directory or in a system build will disable if desired.

1.7	05-Jul-2014	dholland	Reorg docs, part 1: Move all the reference manuals to subdirs of /usr/share/doc/reference. We have subdirs ref1-ref9, corresponding to man page sections 1-9. Everything that's the reference manual for a program (sections 1, 6, 8), C interface (sections 2, 3), driver or file system (section 4), format or configuration (section 5), or kernel internal interface (section 9) belongs in here. Section 7 is a little less clear: some things that might go in section 7 if they were a man page aren't really reference manuals. So I'm only putting things in reference section 7 that are (to me) clearly reference material, rather than e.g. tutorials, guides, FAQs, etc. This obviously leaves some room for debate, especially without first editing the docs with this distinction in mind, but if people hate what I've done things can always be moved again. Note also that while roff macro man pages traditionally go in section 7, I have put all the roff documentation (macros, tools, etc.) in one place in reference/ref1/roff. This will make it easier to find and also easier to edit it into some kind of coherent form.
1.6	05-Jul-2014	dholland	Rework /usr/share/doc. Update the <bsd.doc.mk> infrastructure, and update the docs to match the new infrastructure. - Build and install text, ps, pdf, and/or html, not roff sources. - Don't wire the chapter numbers into the build system, or use them in the installed pathnames.

1.5	10-Jul-2003	lukem	branches: 1.5.60; 1.5.72; Rename a large chunk of the make(1) variables which refer to a program/tool from "FOO" to "TOOL_FOO". The new variables are: TOOL_ASN1_COMPILE TOOL_CAP_MKDB TOOL_CAT TOOL_CKSUM TOOL_COMPILE_ET TOOL_CONFIG TOOL_CRUNCHGEN TOOL_CTAGS TOOL_DB TOOL_EQN TOOL_FGEN TOOL_GENCAT TOOL_GROFF TOOL_HEXDUMP TOOL_INDXBIB TOOL_INSTALLBOOT TOOL_INSTALL_INFO TOOL_M4 TOOL_MAKEFS TOOL_MAKEINFO TOOL_MAKEWHATIS TOOL_MDSETIMAGE TOOL_MENUC TOOL_MKCSMAPPER TOOL_MKESDB TOOL_MKLOCALE TOOL_MKMAGIC TOOL_MKTEMP TOOL_MSGC TOOL_MTREE TOOL_PAX TOOL_PIC TOOL_PREPMKBOOTIMAGE TOOL_PWD_MKDB TOOL_REFER TOOL_ROFF_ASCII TOOL_ROFF_DVI TOOL_ROFF_HTML TOOL_ROFF_PS TOOL_ROFF_RAW TOOL_RPCGEN TOOL_SOELIM TOOL_SUNLABEL TOOL_TBL TOOL_UUDECODE TOOL_VGRIND TOOL_ZIC For each, provide default in <bsd.sys.mk> of the form: TOOL_FOO?= foo and for the ${USETOOLS}=="yes" case in <bsd.own.mk>, provide override: TOOL_FOO= ${TOOLDIR}/bin/${_TOOL_PREFIX}foo Document all of these in bsd.README. This cleans up a chunk of potential (and actual) namespace collision within our build infrastructure, as well as improves consistency in the share/mk documentation and provision of appropriate defaults for each of these variables.

Rather than simply mapping o -> f as was done in the PR, or mapping o -> l as was done in FreeBSD, I have implemented full support for the "o" option. If a postscript filter does not exist in the printcap file however, it will default to "l" handling. With this change, you can now specify a "pf" or postscript filter in your printcap, and have it handle postscript files sent to it with "lpr -o". The "o" format in lpd is specified in RFC1179 as being a valid format flag.

1.20	17-Jan-2006	garbled	Fix PR bin/14247 This PR claims that MacOSX 10.1 cannot print postscript files to a NetBSD lpd because the mac will tag the file with an "o" for postscript, which we do not handle. Rather than simply mapping o -> f as was done in the PR, or mapping o -> l as was done in FreeBSD, I have implemented full support for the "o" option. If a postscript filter does not exist in the printcap file however, it will default to "l" handling. With this change, you can now specify a "pf" or postscript filter in your printcap, and have it handle postscript files sent to it with "lpr -o". The "o" format in lpd is specified in RFC1179 as being a valid format flag.

This change adds the ability to specify port@host in the rm element of printcap(5). Tested to work with both a standard lpd setup and one running on special ports.

No third-party applications are expected to use it. - the function was introduced very recently, when rcmd.c was made IPv6-ready. - the only customer in NetBSD tree is lpd.

No third-party applications are expected to use it. - the function was introduced very recently, when rcmd.c was made IPv6-ready. - the only customer in NetBSD tree is lpd.

Rather than simply mapping o -> f as was done in the PR, or mapping o -> l as was done in FreeBSD, I have implemented full support for the "o" option. If a postscript filter does not exist in the printcap file however, it will default to "l" handling. With this change, you can now specify a "pf" or postscript filter in your printcap, and have it handle postscript files sent to it with "lpr -o". The "o" format in lpd is specified in RFC1179 as being a valid format flag.
1.44	04-Jan-2006	garbled	Address PR bin/12112 Lpd has the ability to start on a port other than "printer" but has no way to connect to a remote lpd on that port. This change adds the ability to specify port@host in the rm element of printcap(5). Tested to work with both a standard lpd setup and one running on special ports.

Rather than simply mapping o -> f as was done in the PR, or mapping o -> l as was done in FreeBSD, I have implemented full support for the "o" option. If a postscript filter does not exist in the printcap file however, it will default to "l" handling. With this change, you can now specify a "pf" or postscript filter in your printcap, and have it handle postscript files sent to it with "lpr -o". The "o" format in lpd is specified in RFC1179 as being a valid format flag.

1.33	17-Jan-2006	garbled	Fix PR bin/14247 This PR claims that MacOSX 10.1 cannot print postscript files to a NetBSD lpd because the mac will tag the file with an "o" for postscript, which we do not handle. Rather than simply mapping o -> f as was done in the PR, or mapping o -> l as was done in FreeBSD, I have implemented full support for the "o" option. If a postscript filter does not exist in the printcap file however, it will default to "l" handling. With this change, you can now specify a "pf" or postscript filter in your printcap, and have it handle postscript files sent to it with "lpr -o". The "o" format in lpd is specified in RFC1179 as being a valid format flag.

(1.2 release is, however, and this should be pulled up and released ASAP) The previous version (1.11) checked into current limits the duration of setuid-root periods much more than the 1.2 released version does, so the attacker DID get a shell, but it was not a root shell.
1.11	10-Aug-1996	explorer	Fix printing over non-root-exported NFS at least. The problem here is setuid(euid) is used far too much. Since I removed many of these calls, and added no new ones, I do not think this weakens security. In fact, it quite likely improves it quite a bit, since access() is called as the real userid, and the file is opened for printing as the real userid rather than the (setuid-root) effective one.
