Revision 0b2dc83906cf1e694e48003eae5df8fa63f76fd9 authored by Jakub Sitnicki on 06 February 2020, 11:16:51 UTC, committed by Daniel Borkmann on 07 February 2020, 21:36:26 UTC
We need to have a synchronize_rcu before free'ing the sockhash because any
outstanding psock references will have a pointer to the map and when they
use it, this could trigger a use after free.
This is a sister fix for sockhash, following commit 2bb90e5cc90e ("bpf:
sockmap, synchronize_rcu before free'ing map") which addressed sockmap,
which comes from a manual audit.
Fixes: 604326b41a6fb ("bpf, sockmap: convert to generic sk_msg interface")
