Re: BUG at security/selinux/avc.c:883 (was: Re: linux-next: Tree
for July 17: early crash on x86-64)
SELinux needs MAY_APPEND to be passed down to the security hook.
Otherwise, we get permission denials when only append permission is
granted by policy even if the opening process specified O_APPEND.
Shows up as a regression in the ltp selinux testsuite, fixed by
this patch.
