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
If backtrace support is turned on, build raise() and abort() with unwind info (fixup 4c9b7f3c21ff21c199e54bfad2fdf3445fa4573d). Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
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.

2011-11-23libc: do not rely upon ulimit kernel syscall.Carmelo Amoroso
On several architectures __NR_ulimit syscall number is currently defined but it is remapped onto sys_ni_syscall, while on other architectures they are not longer defined. So use {get,set}rlimit only to implement ulimit interface. It fixes LTP ulimit01 test case.
