Subject: [conntrack-tools PATCH] conntrack: Fix for ENOENT in mnl_nfct_delete_cb()
Date: Tue,  5 Nov 2024 22:33:10 +0100	[thread overview]
Message-ID: <20241105213310.24726-1-phil@nwl.cc> (raw)

Align behaviour with that of mnl_nfct_update_cb(): Just free the
nf_conntrack object and return. Do not increment counter variable, and
certainly do not try to print an uninitialized buffer.

Fixes: a7abf3f5dc7c4 ("conntrack: skip ENOENT when -U/-D finds a stale conntrack entry")
