* Fix the email address formats in some posix_spawn(3) manpages.Ed Schouten2008-07-282-2/+2
| | | | | | | | | | | It seems I made a small bug when writing some of the posix_spawn(3) manpages. Remove the redundant "Ed Schouten", which broke the AUTHORS section. Approved by: philip (mentor, implicit) Notes: svn path=/head/; revision=180876

| | | | | | | | | | | | | | | "If you don't get a review within a day or two, I would firmly recommend backing out the changes" back out all my changes, i.e. not comes from merging from OpenBSD as unreviewed by secteam@ yet. (OpenBSD changes stays in assumption they are reviewd by OpenBSD) Yes, it means some old bugs returned, like not setted rs_stired = 1 in arc4random_stir(3) causing double stirring.

* Begin de-spaghettifying the code that handles positional arguments.David Schultz2008-06-292-188/+306
| | | | | | | | | | | | | | | | | In particular, encapsulate the state of the type table in a struct, and add inline functions to initialize, free, and manipulate that state. This replaces some ugly macros that made proper error handling impossible. While here, remove an unneeded test for NULL and a variable that is initialized (many times!) but never used. The compiler didn't catch these because of rampant use of the same variable to mean different things in different places. This commit should not cause any changes in functionality.

* Two FP-related setjmp/longjmp changes:David Schultz2008-06-282-2/+20
| | | | | | | | | | | | | | | | | | 1. Save and restore the control part of the MXCSR in addition to the i387 control word to ensure that the two are consistent. Note that standards don't require longjmp to restore either control word, and none of Linux, MacOS X 10.3 and earlier, NetBSD, OpenBSD, or Solaris do it. However, it is historical FreeBSD behavior, and bde points out that it is needed to make longjmping out of a signal handler work properly, given the way FreeBSD clobbers the FPU state on signal handler entry. 2. Don't clobber the FPU exception flags in longjmp. C99 requires them to remain unchanged. Notes: svn path=/head/; revision=180080

| | | | | | | | | | | | | | | | | | | | | | | | - It is opt-out for now so as to give it maximum testing, but it may be turned opt-in for stable branches depending on the consensus. You can turn it off with WITHOUT_SSP. - WITHOUT_SSP was previously used to disable the build of GNU libssp. It is harmless to steal the knob as SSP symbols have been provided by libc for a long time, GNU libssp should not have been much used. - SSP is disabled in a few corners such as system bootstrap programs (sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves. - It should be safe to use -fstack-protector-all to build world, however libc will be automatically downgraded to -fstack-protector because it breaks rtld otherwise. - This option is unavailable on ia64. Enable GCC stack protection (aka Propolice) for kernel: - It is opt-out for now so as to give it maximum testing. - Do not compile your kernel with -fstack-protector-all, it won't work.

* Turn execvpe() into an internal libc routine.Ed Schouten2008-06-236-19/+12
| | | | | | | | | | | | | | | Adding exevpe() has caused some ports to break. Even though execvpe() is a useful routine, it does not conform to any standards. This patch is a little bit different from the patch sent to the mailing list. I forgot to remove execvpe from the Symbol.map (which does not seem to miscompile libc, though).

It doesn't seem to be used outside grantpt.c, which means we can make it static and remove it from the Symbol.map.
