2015-10-05libc: fix setting return value and errno in fallocate()Yuriy Kolerov
fallocate system call must return 0 on success. On error, -1 is returned and errno is set to indicate the error. However there is an error in fallocate which is fixed by this patch - it does not set errno and returns invalid value on error (it returns error code instead of -1). This error is detected in LTP's test kernel/syscalls/fallocate02: ----------->8---------- fallocate(..., 1, 0, 1024) failed, expected errno:9: TEST_ERRNO=0 fallocate(..., 1, -1024, 1024) failed, expected errno:22: TEST_ERRNO=0 fallocate(..., 1, 1024, -1024) failed, expected errno:22: TEST_ERRNO=0 fallocate(..., 1, 12288, 0) failed, expected errno:22: TEST_ERRNO=0 fallocate(..., 1, 12288, -1024) failed, expected errno:22: TEST_ERRNO=0 fallocate(..., 1, -24576, 1024) failed, expected errno:22: TEST_ERRNO=0 ----------->8---------- Signed-off-by: Yuriy Kolerov <yuriy.kolerov@synopsys.com>
2015-09-15NPTL: fix CFLAGS for cancellation pointsMax Filippov
Stack unwinding that happens during NPTL thread cancellation needs cancellable syscall wrapper functions to be compiled with -fexceptions -fasynchronous-unwind-tables to be able to unwind to cleanup handlers registered before syscall invocation. Add these flags for all cancellable syscall wrappers. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

2015-08-27nptl_db/db_info: fix the incorrect initial size for dtvpJunling Zheng
When debugging a program on ARMv7 with thread-local storage declared using "__thread", attempting to print a thread-local variable will result in the following message: Cannot find thread-local storage for Thread <snip> (LWP <snip>), executable file /tmp/tls: capability not available This can be traced back to uclibc libpthread/nptl_db/td_thr_tls_get_addr.c which gdb uses to look up the address of the TLS. The function returns TD_NOCAPAB due to a mismatch in size between the DTV pointer and the size recorded in the db description. The problem lies in libpthread/nptl_db/db_info.c which initializes the db with the sizeof the union dtv. Instead it should be the sizeof a pointer to union dtv. Fixed the initial size for dtvp to sizeof a pointer, instead of sizeof the union.

2015-07-22ARCv2: update memset() so it could be used without double load/storesClaudiu Zissulescu
Existing version of memset() relies on existence of 64-bit load/stores. While ARC HS38 may not have those instructions implemented in SoC. Proposed implementation checks if "-mno-ll64" option was passed to gcc (for ARCv2 "-mll64" is set implicitly by default) by checking __LL64__ definition and if it is not defined uses 32-bit load/stores.

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.
