H A D | pkey_siginfo.c | c27f2fd1 Sun Jul 26 23:00:40 CDT 2020 Sandipan Das <sandipan@linux.ibm.com> selftests/powerpc: Add test for pkey siginfo verification
Commit c46241a370a61 ("powerpc/pkeys: Check vma before returning key fault error to the user") fixes a bug which causes the kernel to set the wrong pkey in siginfo when a pkey fault occurs after two competing threads that have allocated different pkeys, one fully permissive and the other restrictive, attempt to protect a common page at the same time. This adds a test to detect the bug.
