2015-07-03test/tls: xtensa: fix TLS_LD definitionMax Filippov
TLS_LD should use linker-provided symbol _TLS_MODULE_BASE_ instead of symbol it resolves to get thread pointer, otherwise linker relaxation doesn't work correctly, adding extra offset to thread-local variable address. This fixes most of tls/tst-tls* tests. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
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: add ret_ERRVAL definitionMax Filippov
ret_ERRVAL is used by mq_timedsend and mq_timedreceive, it needs to be defined to retw, otherwise error return from those functions segfaults. This fixes the following testsuite failures: .... tst-mqueue1 FAIL tst-mqueue1 got 1 expected 0 Didn't expect signal from child: got `Segmentation fault' .... tst-mqueue2 FAIL tst-mqueue2 got 1 expected 0 Didn't expect signal from child: got `Segmentation fault' .... tst-mqueue3 FAIL tst-mqueue3 got 1 expected 0 Didn't expect signal from child: got `Segmentation fault' .... tst-mqueue4 FAIL tst-mqueue4 got 1 expected 0 Didn't expect signal from child: got `Segmentation fault' .... tst-mqueue5 FAIL tst-mqueue5 got 1 expected 0 Didn't expect signal from child: got `Segmentation fault' .... tst-mqueue6 FAIL tst-mqueue6 got 1 expected 0 Didn't expect signal from child: got `Segmentation fault' Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
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>

2015-06-10siginfo: add signal info for seccomp related SIGSYSDaniel Golle
uClibc doesn't define signal info for the SIGSYS signal which is issued in case of hitting a syscall prohibited by seccomp. This is sad as it makes debugging seccomp filter policies impossible on some architectures (at least ARM and PowerPC, maybe also others) which do not coincidentally set si_value.sival_int as the syscall number. To fix this, import the definitions and macros needed from glibc. Signed-off-by: Daniel Golle <daniel@makrotopia.org> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2015-06-10test/silly: Extend include path.Andrew Burgess
When attempting to build uClibc under buildroot, including building the tests, the silly tests don't currently compile, a result of attempting to build using a compiler that does not yet have an installed version of uClibc available. The error is a missing header file, specifically atomic.h. Taking inspiration from the nptl tests, I have extended the EXTRA_CFLAGS variable to add the required include paths. The tests can now be built under buildroot.

2015-06-10_scanf.c: Implement 'm' modifier for 'c' and '[' conversions.Will Newton
The current code implements the 'm' modifier only for 's' conversions and would cause a segfault if it was used for 'c' or '[' conversions. This patch extends the code to cover these cases too. The original version could write scanned data outside the passed buffer because index i used in the '[' conversion handling block was clobbered.

Previously V=1 did print abbreviated commands and V=2 the full commands. Kbuild-based build-systems behave in the opposite way and this is apparently confusing or inconvenient for users so swap our V handling to be in line with kbuild (and automake as far as V=0 / V=1 is concerned).
