Vineet Gupta 93312b6da4 ARC: mm: allow mprotect to make stack mappings executable ... mprotect(EXEC) was failing for stack mappings as default vm flags was missing MAYEXEC. This was triggered by glibc test suite nptl/tst-execstack testcase What is surprising is that despite running LTP for years on, we didn't catch this issue as it lacks a directed test case. gcc dejagnu tests with nested functions also requiring exec stack work fine though because they rely on the GNU_STACK segment spit out by compiler and handled in kernel elf loader. This glibc case is different as the stack is non exec to begin with and a dlopen of shared lib with GNU_STACK segment triggers the exec stack proceedings using a mprotect(PROT_EXEC) which was broken.
