Lock Order Reversal on 7.0-STABLE with pf and ipfw / dummynet

World was cvsupped on March 6th, around 18:00 GMT.

Built and installed kernel + world, with options WITNESS and

Short background:  7.0-RELEASE had excellent performance on the machine,
but it would randomly lock up after some hours (usually over 10 hours).
The lockups were hard, meaning nothing seemed to work (NumLock didn't
toggle the keyboard LED, no replies to ping, no disk activity).  We
changed the motherboard and RAM and had the same behaviour.  6.2-REL is
rock solid on this machine (had over 50 days uptime), but upgrading to
6.3-REL made it lock up just like 7.0 (so we put 6.2 back and accepted
the lower performance for the time being).

The LOR messages from dmesg of 7.0-STABLE are as follows:

lock order reversal:
 1st 0xffffffffb19e0680 pf task mtx (pf task mtx) @ /usr/src/sys/modules/pf/../../contrib/pf/net/pf.c:6729
 2nd 0xffffff00042ea0f0 radix node head (radix node head) @ /usr/src/sys/net/route.c:147
lock order reversal:
 1st 0xffffffff80938508 PFil hook read/write mutex (PFil hook read/write mutex) @ /usr/src/sys/net/pfil.c:73
 2nd 0xffffffff80938c48 tcp (tcp) @ /usr/src/sys/netinet/tcp_input.c:400

More details about the machine in the attached dmesg.  It's a SMP with
4GB of RAM, 3 gigabit cards (em0, em1 and, depending on the motherboard
we used, either bge0 or msk0).  Only em0 is linked to a gigabit port,
the others are 100Mbits/s

SCTP and the wireless interfaces.  WITNESS and WITNESS_SKIPSPIN were
only added in the hope of figuring out what locks it up, and they did
signal these 2 LORs.

pf and pflog are loaded as modules (pf_enable and pflog_enable set to
yes in rc.conf).

- The ipfw/dummynet side:

I use net.link.ether.ipfw = 1 for MAC address checking, ipfw + dummynet
for traffic shaping (4 queues at 95Mbits/s for the 2 external interfaces
in/out, and 4 more queues for traffic that goes outside the AS group for
which we have fast access).  Deciding which queue traffic goes in
depends on its source address and whether its destination is in ipfw
tables 1, 2 or none.  These tables are synchronized from pf tables via a
custom script in crontab, which runs every 3 minutes.  The pf tables
used as source for these are controlled by OpenBGPD.

- The pf side:

Filtering is done here, as is policy routing.  Filtering also contains
redirecting to a transparent squid proxy of traffic destined to port 80
but not bound for networks received via BGP and saved to tables <metro>
and <special>.  Metro and special port 80 traffic goes directly to
the destination server.

Traffic from net1 and net2 is routed via the "other" external interface,
which doesn't contain the default route... with the exception of traffic
to pf table <special> (from BGP, same as table 2 in ipfw).  Traffic to
<special> is routed via fastroute in pf (meaning using the default

Attached are full dmesg and the kernel config.

I still have access to the hard drive with 7.0-STABLE on it, but not the
motherboard/CPU and the network cards... they are running off the hard
drive with 6.2 on it.
