netfilter: nf_tables: add missing ->release_ops() in error path of newrule()
[ Upstream commit
b25a31bf0ca091aa8bdb9ab329b0226257568bbe ]
->release_ops() callback releases resources and this is used in error path.
If nf_tables_newrule() fails after ->select_ops(), it should release
resources. but it can not call ->destroy() because that should be called
after ->init().
At this point, ->release_ops() should be used for releasing resources.
Test commands:
modprobe -rv xt_tcpudp
iptables-nft -I INPUT -m tcp <-- error command
lsmod
Result:
Module Size Used by
xt_tcpudp 20480 2 <-- it should be 0
