* Save/restore errno in all safe wrappersLaurent Bercot2026-01-011-3/+5

* Huge incompatible changes.Laurent Bercot2021-07-281-2/+2
| | | | | | | | | | | | - Obsolete skalibs/environ.h and skalibs/getpeereid.h removed. - rc4 and md5 removed. - All *_t types renamed to avoid treading on POSIX namespace. - subgetopt() renamed to lgetopt(). - signal functions reworked; skasigaction removed; sig_stack removed - Various functions removed: skaoffsetof(), selfpipe_untrap() - New posixplz function: munmap_void.

* Separate and expose ancil_recv_fd/ancil_send_fdLaurent Bercot2020-10-261-1/+1
| | | | | | | The goal is to make late channel creation easy, as opposed to textclient which always creates a new channel at start time. This commit also moves posixishard.h inclusions as late as possible.
* Add skalibs/posixishard.hLaurent Bercot2019-02-191-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | This will break things. It's a known issue. Patches to other packages will come later, to adapt them to the new API. To work around brokenness, there needs to be *two* different headers: 1. one to be used before including system headers, that maximizes visibility by enabling system-dependent feature test macros (that will be tested by system headers) 2. one to be used after including system headers, that performs preprocessor tests and defines. skalibs/nonposix.h is the first one. Previously, there was no second one, and the tests were scattered all over. There was a strnlen declaration in skalibs/posixplz.h (which serves a totally different function: declaring things that should be in POSIX, but *are not*, i.e. working around problems in the standard, instead of problems in systems failing to respect the standard), a build-time sysdep for error.h, #defines for MSG_NOSIGNAL, etc. etc. skalibs/posixishard.h now is the second one, and centralizes all the tests. As a result, the eproto sysdep is unnecessary and has been removed. skalibs/error.h is now a static header, it is not built anymore.

* Applied Roman Kimov's fixesv2.3.1.3Laurent Bercot2015-03-131-1/+1

* - Bugfixes in unixmessage/skaclient (short writes / fd leakage / DoS)v2.1.0.0Laurent Bercot2015-01-061-17/+39
| | | | | | - ABI change: unixmessage protocol header is now 6 bytes (was 8) - API change: skaclient_start(_async) now takes an "options" argument - version increase to 2.1.0.0
* Safe wrappers around sendmsg and recvmsg in unixmessage primitivesLaurent Bercot2014-12-311-3/+6

* So MSG_WAITALL can block even with MSG_DONTWAIT... wtfbsdseriously.Laurent Bercot2014-12-211-3/+10
| | | | | Only include MSG_WAITALL when it's tested nb, then. Also test yet another fix for the tryancilautoclose FreeBSD problem.
* So the non-portable MSG_DONTWAIT may alleviate the problem... mightLaurent Bercot2014-12-211-12/+11
| | | | as well use it on architectures that support it.
* Found the BSD unixmessage bug. recvmsg(..., MSG_WAITALL) blocksLaurent Bercot2014-12-201-6/+15
| | | | | | until buffer full or socket shutdown on BSD, *even if the socket is nonblocking*. So I added an "okwaitall" sysdeps, and won't set MSG_WAITALL on retarded systems.
* unixmessage_receive: don't read more than 1 message at a timeLaurent Bercot2014-12-141-2/+6
