2015-03-25utmp: favour POSIX utmpx over SVID utmpBernhard Reutner-Fischer
Note: _PATH_UTMPX == _PATH_UTMP and the utmp struct is identical to the utmpx struct so this only changes the external API entrypoints and NOT the underlying data source. This saves about 500b (~1300b from previously ~1950) while at it. Signed-off-by: Bernhard Reutner-Fischer <>

2009-09-05utent.c: fix a few bugs, and shrink a bitDenys Vlasenko
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 <>

things, and avoid potential deadlocks caused when a thread holding a uClibc internal lock get canceled and terminates without releasing the lock. This change also provides a single place, bits/uClibc_mutex.h, for thread libraries to modify to change all instances of internal locking.

2006-02-11rholzmann writes in Bug 716:Mike Frysinger
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.

2003-12-27Fix a long-standing bug with pthreads. A couple of linuxthreads filesManuel Novoa III
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.
