Hi,

This series fix the recent seccomp update for the User-mode Linux architecture
(32-bit and 64-bit) since commit 26703c636c1f3272b39bd0f6d04d2e970984f1b6
(close the hole where ptrace can change a syscall out from under seccomp).

Regards,

Mickaël Salaün (3):
  um/ptrace: Fix the syscall_trace_leave call
  um/ptrace: Fix the syscall number update after a ptrace
  seccomp: Remove 2-phase API documentation

Ah, perfect! Thanks for fixing this! James, can you pick this up for -next?

Acked-by: Kees Cook <redacted>
James, can you take these fixes for v4.8? We'll need them for um to
work correctly again. (They appear to still be missing from -next.)
I'm pretty sure I don't have these patches, can you or the author send 
them to me?
