Subject: [PATCH v2 net 0/2]  openvswitch: syzbot splat fix and introduce selftest
Date: Tue, 25 Oct 2022 06:50:16 -0400	[thread overview]
Message-ID: <20221025105018.466157-1-aconole@redhat.com> (raw)

Syzbot recently caught a splat when dropping features from
openvswitch datapaths that are in-use.  The WARN() call is
definitely too large a hammer for the situation, so change
to pr_warn.

Second patch in the series introduces a new selftest suite which
can help show that an issue is fixed.  This change might be
more suited to net-next tree, so it has been separated out
as an additional patch and can be either applied to either tree
based on preference.

Aaron Conole (2):
  openvswitch: switch from WARN to pr_warn
  selftests: add openvswitch selftest suite
