This patch fixes this issue. This issue is reported in LTP (testcase: sigaltstack02.c). Testcase failed when sigaltstack() called with stack size "MINSIGSTKSZ - 1" Since in Glibc-2.22, MINSIGSTKSZ is set to 5120 but in kernel it is set to 2048 so testcase gets failed. Testcase Output: sigaltstack02 1 TPASS : stgaltstack() fails, Invalid Flag value,errno:22 sigaltstack02 2 TFAIL : sigaltstack() returned 0, expected -1,errno:12 Reported Issue in Glibc Bugzilla: https://sourceware.org/bugzilla/show_bug.cgi?id=16850 Bugfix in Glibc-2.22: https://sourceware.org/git/gitweb.cgi?p=glibc.git;a=blob;f=sysdeps/unix/ sysv/linux/aarch64/bits/sigstack.h;h=8f2fb76e3e81734ef8a9cf9ae40daf4705 f31c35;hb=b763f6ae859ecea70a5dacb8ad45c71d5f667e2e Signed-off-by: Akhilesh Kumar <akhilesh.k@...sung.com> Signed-off-by: Manjeet Pawar <manjeet.p@...sung.com> Signed-off-by: Rohit Thapliyal <r.thapliyal@...sung.com> --- v1 -> Changes in uapi overall header v2 -> Changes done in arm64 headers arch/arm64/include/uapi/asm/signal.h | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/arch/arm64/include/uapi/asm/signal.h b/arch/arm64/include/uapi/asm/signal.h index 8d1e723..5ac56cf 100644 --- a/arch/arm64/include/uapi/asm/signal.h +++ b/arch/arm64/include/uapi/asm/signal.h @@ -21,4 +21,9 @@ #include <asm-generic/signal.h> +#undef MINSIGSTKSZ +#undef SIGSTKSZ +#define MINSIGSTKSZ 5120 +#define SIGSTKSZ 16384 + #endif -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
