Subject: [PATCH net] net/sched: act_gate: Unlock ->tcfa_lock in tc_setup_flow_action()
Date: Tue, 20 Oct 2020 17:34:31 +0200 [thread overview]
Message-ID: <12f60e385584c52c22863701c0185e40ab08a7a7.1603207948.git.gnault@redhat.com> (raw)
We need to jump to the "err_out_locked" label when
tcf_gate_get_entries() fails. Otherwise, tc_setup_flow_action() exits
with ->tcfa_lock still held.
Fixes: d29bdd69ecdd ("net: schedule: add action gate offloading")
Signed-off-by: Guillaume Nault <gnault@redhat.com>
