2015-06-30NPTL/arc: notify kernel of the TP valueVineet Gupta
Native gdb makes a ptrace (GET_THREAD_AREA) which needs to return the TP. however when libc sets up TP reg (for main thread), it doesn't call arc_settls syscall so kernel doesn't know of TP register details (moreso because clone doesnt have SETTLS flag) Note that kernel doesn't know about r25 being TP etc. This commit got lost in merge of NPTL tools into arc-mainline-dev and showed up again as STAR 9000919529 (native gdb can't debug threaded apps) ------->8--------------- [ARCLinux]# gdb ./pth Reading symbols from ./pth...(no debugging symbols found)...done.

2015-06-23xtensa: fix stack frame size for NPTLMax Filippov
Cancellable syscalls use call8 to call functions that enable/disable cancellation, thus they cannot use the default FRAMESIZE. Redefine FRAMESIZE for such syscalls. This fixes the following testsuite failure: .... tst-mqueue8 FAIL tst-mqueue8 got 1 expected 0 going to cancel mq_receive in-time in-time mq_receive cancellation succeeded going to cancel mq_receive early Didn't expect signal from child: got `Segmentation fault' Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

2014-12-15mkostemp: 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.

2014-04-01Fix 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.

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.

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.
