2014-12-10mkostemp: fix implementationAnthony G. Basile
mkostemp(char *template, int flags) generates a unique temporary filename from a template. The flags parameter accepts three of the same flags as open(2): O_APPEND, O_CLOEXEC, and O_SYNC. The current implementation of mkostemp(3) does not respect the flags and in fact confuses the flags with the file mode which should always be S_IRUSR | S_IWUSR. This patch corrects this issue.

2014-06-12NPTL: Fix undefined reference to PRIVATE_FUTEX with 2.6.18 kernelDan Moulding
When compiling against the 2.6.18 kernel headers, during linking of the NPTL library it runs into a "undefined reference to PRIVATE_FUTEX" error in pthread_cond_timedwait.S. This resolves the problem by ensuring that the definition for PRIVATE_FUTEX is made available to pthread_cond_timedwait.S.

2014-04-01Fix warnings in MIPS buildSteve Ellcey
This patch fixes the rest of the set-but-not-used warnings in the MIPS code by using attribute_unused and also fixes some conversion warnings by changing __arch_compare_and_exchange_xxx_[8|16]_int. Assigning __cmp (int type) to __prev (pointer type) generates a warning. Assigning zero to each separately avoids this warning without having to add a cast.

2014-02-02mips: silence 'set but not used' warningsSteve Ellcey

2013-07-04libpthread: pthread_exit in static app. segfaultsFilippo ARCIDIACONO
Static applications that call pthread_exit on the main thread segfault. This is because after a thread terminates __uClibc_main decrements __nptl_nthreads which is only defined in pthread_create. Therefore the right solution is to add a requirement to pthread_create from pthread_exit.

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>
