2013-01-16getpwnam: hide relocationBernhard Reutner-Fischer
The non-reentrant version of getpwnam is used in the RPC code (for !HAS_REENTRANT_RPC) Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2013-01-10libc: add {get,set,swap,make}context user context manipulation functionsFlorian Fainelli
Add the obsolescent SUSv3 family of user context manipulating functions for arm, i386, mips, x86_64.

2012-11-18drop support for pre ISO-C compilersMike Frysinger
This drops __signed, __volatile, and __const. Only the latter was used in the code base, and for uClibc, not consistently. Much of the code used plain "const" which meant "__const" was useless. Really, the point of this is to stay in sync with what glibc did. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-11-18Replace FSF snail mail address with URLsMike Frysinger
This matches a similar change made to glibc. No functional changes here. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-11-16include/elf.h: update for ELFOSABI_* changes.Thomas Schwinge
ELFOSABI_GNU replaces ELFOSABI_LINUX, the latter is kept as a compatibility alias, and ELFOSABI_HURD is removed. See the table on <http://www.sco.com/developers/gabi/latest/ch4.eheader.html#osabi> for reference.

2012-11-14libc/stdlib: add mkostemp helpersMike Frysinger
Some projects (like udev) are starting to use this. Imported from glibc. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-11-14libc/sysdeps: add dup3 syscall wrapperMike Frysinger
Some projects (like udev) are starting to use this. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2012-06-15signal: remove sigblock, siggetmask and sigsetmaskPeter S. Mazinger

2012-06-15sigpause.c: provide the X/Open variant, since the BSD version is deprecatedPeter S. Mazinger
Do not export __sigpause. Provide __bsd_sigpause (unprototyped) if anyone may need it. Adapt cancellation to use cancel.h. Signed-off-by: Peter S. Mazinger <ps.m@gmx.net> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2012-06-15socketcalls.c: rewrite to use cancel.hPeter S. Mazinger
__socketcall.c: remove guard, we definitely need this syscall Re-added guard plus added comment (Bernhard) Signed-off-by: Peter S. Mazinger <ps.m@gmx.net> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2012-06-15rework cancellation for sigwait, sigtimedwait and sigwaitinfoPeter S. Mazinger
sigtimedwait: - provide __sigtimedwait_nocancel - use __SYSCALL_SIGSET_T_SIZE instead of _NSIG / 8 - do not provide __sigtimedwait - guard a section to avoid failure on archs if SI_TKILL/SI_USER are not defined sigwaitinfo: - simply use sigtimedwait since that handles cancellation already sigwait: - use non-cancellable functions (sigtimedwait, sigsuspend) - get rid of code already done in __sigtimedwait_nocancel Signed-off-by: Peter S. Mazinger <ps.m@gmx.net> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

LT_OLD provides cancellable versions, do it for all THREADS. llseek.c: use newly added macros for offset handling. Add a comment about endianness issue around offset. Compile llseek.c only on 32bit archs. Provide aliases for 64bit archs or if syscall is not available. Signed-off-by: Peter S. Mazinger <ps.m@gmx.net> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2012-06-15sigsuspend.c: add cancellation support independently of rt_sigsuspendPeter S. Mazinger

2012-06-15fcntl: add cancellation to fcntl64, use cancel.hPeter S. Mazinger
fcntl64 missed cancellation. Guard fcntl64 for 32bit archs. Reuse as much code as possible in __syscall_fcntl.c. Provide alias fcntl64 if that syscall is not available. Signed-off-by: Peter S. Mazinger <ps.m@gmx.net> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2012-06-15waitpid.c: provide __waitpid_nocancel, use cancel.hPeter S. Mazinger

2012-06-15ssp: rework, sync messages with the ones in glibcPeter S. Mazinger
Touch signals only if DODEBUG is enabled. Make the signal selection dependent on DODEBUG, as last resort use SIGKILL. Use internal functions with less arguments, some savings. Fix a warning about unused argument. Do not use openlog/closelog, while there remove their hidden versions. Signed-off-by: Peter S. Mazinger <ps.m@gmx.net> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2012-06-15errno, h_errno: correct them for non-TLSPeter S. Mazinger
Move h_errno related stuff to separate file. Do not hide errno and h_errno for non-TLS, else it keeps being 0. Make __[h_]errno_location weak for non-TLS. Signed-off-by: Peter S. Mazinger <ps.m@gmx.net> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2012-06-15errno and *_init cleanupPeter S. Mazinger
Define a common view of __errno_location, __h_errno_location in common header and use that everywhere, __uClibc_main.c is no special. The rule adopted: for enabled threads we make in libc the __GI_x() variants strong, x() weak and (should) provide another strong x() in libpthread. If threads are disabled, even the __GI_x() variants are weak. _stdio_init,_stdio_term,_locale_init: make all hidden weak in common header Signed-off-by: Peter S. Mazinger <ps.m@gmx.net> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
