Subject: stable regression: revert request for netfilter ipv6 defrag bug
Date: Wed, 24 Oct 2018 12:31:04 +0200 [thread overview]
Message-ID: <20181024103104.72liko3nrf4pqwqa@breakpoint.cc> (raw)
Hi,
please consider reverting
commit 84379c9afe011020e797e3f50a662b08a6355dcf
netfilter: ipv6: nf_defrag: drop skb dst before queueing
It causes kernel crash for locally generated ipv6 fragments
when netfilter ipv6 defragmentation is used.
The faulty commit is not essential for -stable, it only
delays netns teardown for longer than needed when that netns
still has ipv6 frags queued. Much better than crash :-/
commit ids are:
4.4.y: not affected (not backported)
4.9.y: backported as ad8b1ffc3efae2f65080bdb11145c87d299b8f9a
4.14.y: backported as 28c74ff85efd192aeca9005499ca50c24d795f61
4.18.y: (first affected kernel): 84379c9afe011020e797e3f50a662b08a6355dcf
For 4.19.y, you could also wait for a bug fix to hit Linus tree,
I can ping you again once its in:

Thanks,
Florian
