Subject: [PATCH net 0/5] netfilter: bugfixes for net
Date: Wed, 21 Sep 2022 09:38:20 +0200 [thread overview]
Message-ID: <20220921073825.4658-1-fw@strlen.de> (raw)
Hello,
The following set contains netfilter fixes for the *net* tree.
Regressions (rc only):
recent ebtables crash fix was incomplete, it added a memory leak.
The patch to fix possible buffer overrun for BIG TCP in ftp conntrack
tried to be too clever, we cannot re-use ct->lock: NAT engine might
grab it again -> deadlock. Revert back to a global spinlock.
Both from myself.
Remove the documentation for the recently removed
'nf_conntrack_helper' sysctl as well, from Pablo Neira.
The static_branch_inc() that guards the 'chain stats enabled' path
needs to be deferred further, until the entire transaction was created.
From Tetsuo Handa.
Older bugs:
Since 5.3:
nf_tables_addchain may leak pcpu memory in error path when
offloading fails. Also from Tetsuo Handa.
