2010-04-22nptl: fix libc internal, dynamically enabled lockingTimo Teräs
Final iteration to fix libc internal locking if libpthread is pulled in by dlopen call (directly or indirectly). We cannot really use the weak symbol trick for shared build, since the symbols won't get refreshed if libpthread is pulled in dynamically. In glibc, they have #ifdef SHARED magic to either use pthread_functions table, or weaks. But as we shared object files with both builds, this does not sounds good either. The reintroduces the libc weaks.c, but uses them now only with static build. For dynamic build, we still use the symbols with same name, but provide weaks in forward.c so they end up dereferencing the pthread_functions table indirectly if we are not linked to libpthread. Mutex initialization is hard coded as inline, as it needs to happen even if libpthread is not initially loaded.

2010-04-16libc: remove libc weak __pthreads_* wrappersTimo Teras
It is not possible to override for libpthread to override the weak libc definitions. This has never worked in uclibc, and does no longer work in glibc either (unless you use LD_DYNAMIC_WEAK). The proper thing to do is have weak prototypes in libc, and definitions in libpthread only. This way libc runs even if those functions are not defined, but just needs to protect against the NULL values (done by implementing __uclibc_maybe_call). This fix the problems if libc is linked before libpthread or if libpthread is pulled by a dependency library.

2010-04-12libc_regex: __libc_lock primitives are actually available on uClibcCarmelo Amoroso
__libc_lock primitives are actually available on uClibc when threading support is enable, so in this case they can be used. It also fixes the following compiler warnings: In file included from libc/misc/regex/regex.c:55: libc/misc/regex/regex_internal.h:49:1: warning: "__libc_lock_define" redefined [SNIP] libc/misc/regex/regex_internal.h:50:1: warning: "__libc_lock_init" redefined [SNIP] libc/misc/regex/regex_internal.h:51:1: warning: "__libc_lock_lock" redefined [SNIP] libc/misc/regex/regex_internal.h:52:1: warning: "__libc_lock_unlock" redefined Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>

2009-12-13syslog: fix openlog(xx, LOG_KERN) and optimize a bitDenys Vlasenko
The fix: logfac == 0 in openlog(xx, logfac) is allowed now. Corresponding internal openlog() call in vsyslog() uses explicit LOG_USER in order to set it as a default facility. Optimizations: mylock is not recursive now, since a single intenal call of openlog is converted to a call to openlog_internal which assumes that lock is already taken. No recursive locking is possible now. LogFacility is reduced to byte. cache static LogFile in auto variable fd (smaller code). vsyslog with bogus pri parameter wouldn't lock/unlock and mess with signals - it will just return at once. pass NULL as ident string in internal openlog call - same effect as passing LogTag but smaller code. comment out "if (LogTag)" checks - it is never NULL. use the same struct sigaction for setting new sigaction and for saving old one - saves ~32 bytes of stack.
