Subject: netfilter: nf_tables: fix chain filter in nf_tables_dump_rules()
From: Pablo Neira Ayuso <pablo@xxxxxxxxxxxxx>
[ Upstream commit 24c0df82ef7919e4d10cf2e4e65d368eb2e8ea21 ]
ctx->chain may be null now that we have very large object names,
so we cannot check for ctx->chain[0] here.
Fixes: b7263e071aba7 ("netfilter: nf_tables: Allow table names of up to 255 chars")
