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. Signed-off-by: Stephen Smalley <sds@tycho.nsa.gov> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
