2013-02-05libc: atexit: reuse free slots at the end of exit functions tableRonald Wahl
Continuosly dlopen and dlclose of shared object will cause a memory leak in atexit function. This fix reuse free slots at the end of the list.

2012-11-29libc/stdlib: localize __unix_grantptMike Frysinger
When ASSUME_DEVPTS is disabled, we end up exporting __unix_grantpt and get a reloc to it from grantpt. Mark it static to fix all of that. Reported-by: Michael Deutschmann <michael@talamasca.ocis.net> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
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>

2012-06-15stdlib.h, arc4random.c: fix arc4random return type to u_int32_tPeter S. Mazinger
Change uint32_t to u_int32_t and uint8_t to u_int8_t, removing completely the dependency on stdint.h. Based on patch by Timo Teraes <timo.teras@iki.fi>. His comment: This also fixes a major bug that stdlib.h includes stdint.h. Things might go very wrong because stdint.h has conditional defines and if stdlib.h is included before #define's for stdint.h we end up missing things and breaking builds (e.g. openjdk).

2012-05-05drop support for old systems lacking vforkMark Salter
Only really old systems (<=linux-2.0) lack a dedicated vfork system call. The code that is in place to support them is causing issues with newer arches that also don't provide a vfork system call -- instead, they do vfork by calling clone in userspace. If anyone cares about these really old systems, they can submit a patch to make the system work with them while not breaking newer systems.

2012-01-23libc: fix signal handling in system()Richard Braun
When built without NPTL support (or for a sparc target), the system() function doesn't conform to its specification. Namely, it uses signal() to install/save/restore signal handlers, which may break applications using custom handlers installed with sigaction(). In addition, it resets the SIGCHLD handler to SIG_DFL instead of blocking the signal, which may result in "lost" signals if a custom handler was installed. Fix system() by replacing uses of signal() with appropriate calls to sigaction() and sigprocmask(). Signed-off-by: Richard Braun <rbraun@sceen.net> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-01-15libc: build abort with unwind-info for backtraceBernhard Reutner-Fischer

2012-01-13libc: allow to backtrace out of abort callCarmelo Amoroso
Build raise and abort function with dwarf2 info by using -fasynchronous-unwind-tables to make backtrace() working across a call to abort. A scenario where it could be useful is within a signal handler that wants to dump a backtrace when catching some signal (i.e SIGABRT). Without having abort & raise built with DWARF2 information, it is not possible for the libgcc stack unwinder to walk through the call stack out of the abort/raise function.

2011-09-15Defeat compiler optimization which assumes function addresses are never NULLDenys Vlasenko
From email: A warning for people who can be hit by the same or similar issue: gcc 4.1.2 with -march=i486 here with -Os and even with -O2 or -O is "optimizing away" the check if (_stdio_term) in libc/stdlib/_atexit.c which results in a "call 0" and a segfault at exit if you do not happen to link in stdio.

2011-04-11Fix malloc alignmentBernd Schmidt
In commit 3e0a1f388, Richard tried to fix malloc alignments by using alignof (double __attribute_aligned__(sizeof (size_t))). This doesn't work, since attribute_aligned overrides the alignment rather than providing a minimum. On C6X, malloc returns four-byte aligned values rather than the necessary eight-byte alignment. It's simpler to use a comparison and pick the bigger of the two values, so that's what I've done. Signed-off-by: Bernd Schmidt <bernds@codesourcery.com>
