Subject: 4.19.4 nf_conntrack_count kernel panic
Date: Mon, 26 Nov 2018 20:46:38 +0100 [thread overview]
Message-ID: <20181126194638.tpwagr7gqzvi3ogf@m.mifar.in> (raw)
4.18.20 works OK, but unfortunately 4.18 series is EOL.
I have Ryzen 1600X, 32 GB RAM, Fedora 28, gcc-8.2.1-5, nosmt=force, igb module for Intel I211,
using XFS filesystems only.
To reproduce, I only do this: connect to VPN using a tunnel (e.g. tun0),
start downloading a file with qbittorrent (allow port for incoming
TCP connections in qbittorrent and iptables) and wait a couple of minutes.
I am also using ipset and connlimit modules.
I reproduced this bug three times.
With 4.18 I use fq+htb and with 4.19 I use CAKE for traffic control.
Only this message in kernel log:
[ 363.935074] TCP: request_sock_TCP: Possible SYN flooding on port 19044. Dropping request. Check SNMP counters.
I get this message with both 4.18.20 and 4.19.4.
