Subject: Bug with Fedora's 2.6.23.9-85 kernel (at least) and ESTABLISHED and SACK
Date: Sun, 27 Jan 2008 22:14:24 -0700	[thread overview]
Message-ID: <479D64B0.10101@acm.org> (raw)

Please CC me on any replies as I am not subscribed.

I was downloading a new Google Earth when I noticed a LOT of max-size 
dropped packets in my firewall log.  I only allow RELATED,ESTABLISHED 
sessions into my firewall.

tcpdump showed that every time Google sent a packet to satisfy the 
missing data identified by SACK, that packet was rejected.  So it must 
have been missing the ESTABLISHED rule.

I fixed the problem by adding an ALLOW source port 80 rule for the 
Google download site IP.

This makes me wonder how often this has happened and I haven't noticed 
it.  Is this a known bug or something new?

BTW, your netfilter Bugzilla is dead or at least 404 missing.
