Hi,
It looks like caaee6234d0 ("ptrace: use fsuid, fsgid, effective creds
for fs access checks") got put into -stable (v4.4.3) without the
required 3dfb7d8cdbc7 ("security: let security modules use
PTRACE_MODE_* with bitmasks").
Please add 3dfb7d8cdbc7 to linux-4.4.y to unbreak Yama (and Smack). :)
Thanks!
-Kees
