* getutid: add a hidden defMike Frysinger2011-12-031-0/+1

* utent.c: fix a few bugs, and shrink a bitDenys Vlasenko2009-09-051-47/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | bug #1: static_fd = -1; close(static_fd); DOH! bug #2: if (utmp_fd == -1) { __setutent(); } if (utmp_fd == -1) { return NULL; } if utmp_fd == -1, we call _setutent(). if __setutent() opens a fd, utmp_fd (a parameter) wouldn't change, the second check is bogus. We need to use static_fd instead in second check. Which makes clear that having utmp_fd parameter is wrong. See the patch for a complete fix. Shrink comes from simplifying fcntl(static_fd, F_SETFD, FD_CLOEXEC): text data bss dec hex filename - 661 8 384 1053 41d libc/misc/utmp/utent.o + 604 8 384 996 3e4 libc/misc/utmp/utent.o Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* rholzmann writes in Bug 716:Mike Frysinger2006-02-111-13/+12
| | | | utent.c has a few problems with mutex locking when used in a binary that was linked with pthreads. The are a few deadlock conditions where functions may be called which lock the utmplock but never release it and where a function that hold the lock calls other functions which try to relock the same lock. For example, notice in the __getutent function the error condition does not unlock the semaphore. The problem is not visible when pthreads isn't used since the lock/unlock functions are NOOP functions.

| | | | | | | | | | | | | | | | were including libc-lock.h which had a bunch of weak pragmas. Also, uClibc supplied a number of no-op weak thread functions even though many weren't needed. This combined result was that sometimes the functional versions of thread functions in pthread would not override the weaks in libc. While fixing this, I also prepended double-underscore to all necessary weak thread funcs in uClibc, and removed all unused weaks. I did a test build, but haven't tested this since these changes are a backport from my working tree. I did test the changes there and no longer need to explicitly add -lpthread in the perl build for perl to pass its thread self tests.
