MINSIGSTKSZ and SIGSTKSZ for ARM64 are not correctly set in latest kernel. 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: Bugfix in Glibc-2.22: [Bug 16850] https://sourceware.org/bugzilla/show_bug.cgi?id=16850 Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Akhilesh Kumar <akhilesh.k@samsung.com> Signed-off-by: Manjeet Pawar <manjeet.p@samsung.com> Signed-off-by: Rohit Thapliyal <r.thapliyal@samsung.com> Signed-off-by: Will Deacon <will.deacon@arm.com>
