netfilter oops (Was: Re: Linux 2.4.18-pre2)
Subsystems (2)
This bounced from lk (due to a malformed address)... apologies for the resend if you get it twice... Just wanted to remove a bit of chaos from the thread. ;)

With 18-pre1, 17-rc2 and 17-preX (can't remember now. It's been a week or so :/) I can get the kernel to consistantly crash after a few minutes by compiling it with ipchains compatability and using masqueraded net connections.
Hi,
Hey.
I haven't forgotten about this little bug. :))

There are three changes which could effect you here. I can't see
anything wrong with any of them, but if you could try reverting them one at a time, and tell me which causes the problem, that'd narrow it down:
Just did a test and it's not masquerading that's causing it. I'll need to convert my filesystems to ext3 first because the crashes are not going to be healthy for this box (or me... 45gig HD involved on a pentium-200) and I'll experiment some more. It may be redirection that's doing it.
Once I narrow down what is actually causing it I'll back out the patches you sent, one by one, until it stops crashing.

Ka-ching! Being able to use a fwded net connection without masq was the needed clue. I looked at the patches and found this one:

As it appeared to deal directly with compatability redirection I removed this one first and recompiled the kernel. Before, a minute or so of browsing via a redirected connection (to squid) would make the box go boom. I've just browsed for 15 minutes to different sites and the box has not gone down.
Now, if you need the oops then holler and I'll see what I can do about getting it to you. Writing it down would be a pain so I may opt for the null-modem cable which may take a week or so for me to get at though.
