Subject: [PATCH v3 0/3] net: unix: fix use-after-free


These patches are against mainline, I can re-base to net-next, just
let me know.

They have been tested against:,
which causes the use-after-free quite quickly and here:



-beef up memory barrier comments in 3/3 (Peter Zijlstra)
-clean up unix_dgram_writable() function in 3/3 (Joe Perches)

Jason Baron (3):
  net: unix: fix use-after-free in unix_dgram_poll()
  net: unix: Convert gc_flags to flags
  net: unix: optimize wakeups in unix_dgram_recvmsg()
