Description

Running a gateway with pf on a 2.7 machine results in periodic crashes with this
message:

panic: assertion: m->m_pkthdr.fw_flags & PF_MBUF_STRUCTURE in mark_ecn

The crashes appear every few hours with low traffic. Copying files with
scp/rsync is a sure way to trigger them.

I have put part of the relevant /var/crash files at this location.

http://dl.zefyris.com/crash.pf/

There are no kernel and vmcore images yet for obvious reasons.

Could you email me your pf.conf?

Never mind, I found it. I mis-coded altq_red... I thought it could
only be called from PF but in fact it can be called directly via
ifq_enqueue().

I have pushed a fix, please test.

Test is conclusive; no more panics when transferring large files.
