Subject: [PATCH] netfilter: ctnetlink: use nf_ct_exp_net() in expectation dump
|
|
|
|
commit a7f57320bbbc67e347bf5fff4b4a9bab980d5956 upstream.
|
|
|
|
Commit 02a3231b6d82 ("netfilter: nf_conntrack_expect: store netns and zone in expectation")
|
|
introduced exp->net so RCU-only expectation paths no longer need to
|
|
dereference exp->master for netns lookups.
|
|
|
|
Commit 3db5647984de ("netfilter: nf_conntrack_expect: skip expectations in other netns via proc")
|
|
updated the proc path accordingly, but ctnetlink_exp_dump_table() still
|
|
compares against nf_ct_net(exp->master).
|
|
|
|
Use nf_ct_exp_net(exp) here as well so the netlink dump path matches
|
|
the rest of the March 2026 expectation netns/RCU cleanup.
|
|
|
