Well, since I can't reproduce the bug, if you think this patch solves my problem, I'll tell my bosses that we can put back the production machine online. But anyway, if there's test you think I can run, I have same the same hardware on a lab using the same setup as the production environment...

But do you think that the bug that squid triggered was caused by the TProxy code? Or is related to the network-stack in some other point. I don't know if this helps, but I'm using ebtables to remove the packets from the bridge, and iptables to redirect the traffic to squid. ebtables rules are: -p IPv4 -i eth0 --ip-proto tcp --ip-dport 80 -j redirect --redirect-target DROP -p IPv4 -i eth1 --ip-proto tcp --ip-sport 80 -j redirect --redirect-target DROP iptables -t mangle -L -n is: iptables -t mangle -L -n Chain PREROUTING (policy ACCEPT) target prot opt source destination DIVERT tcp -- 0.0.0.0/0 0.0.0.0/0 socket extrachain tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:80 ctstate NEW TPROXY tcp -- 0.0.0.0/0 !201.40.162.5 tcp dpt:80 connmark match 0x0 TPROXY redirect 127.0.0.1:3127 mark 0x1/0x1 TPROXY tcp -- 0.0.0.0/0 !201.40.162.5 tcp dpt:80 connmark match 0x1 TPROXY redirect 127.0.0.1:3128 mark 0x1/0x1 TPROXY tcp -- 0.0.0.0/0 !201.40.162.5 tcp dpt:80 connmark match 0x2 TPROXY redirect 127.0.0.1:3129 mark 0x1/0x1 Chain DIVERT (1 references) target prot opt source destination MARK all -- 0.0.0.0/0 0.0.0.0/0 MARK xset 0x1/0xffffffff ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 Chain extrachain (1 references) target prot opt source destination CONNMARK all -- 0.0.0.0/0 0.0.0.0/0 statistic mode nth every 35 CONNMARK and 0x0 CONNMARK all -- 0.0.0.0/0 0.0.0.0/0 statistic mode nth every 35 packet 1 CONNMARK xset 0x1/0xffffffff CONNMARK all -- 0.0.0.0/0 0.0.0.0/0 statistic mode nth every 35 packet 2 CONNMARK xset 0x2/0xffffffff Don't know if the code on these can be traced back to tcp_recvmsg() accessing some wrong memory address...

It could be corruption from elsewhere.

Since the function that had the problem was tcp_recvmsg and we're talking about a squid process, we're either talking about a typical webserver-objet response, or about about an incorrect/faulty http request from the user. Like I told Mr. Dumazet, since on the squid logs I got a: 2010/07/08 14:51:10| clientTryParseRequest: FD 6088 (187.16.240.122:2035) Invalid Request Only a second before the bug entry on syslog, I suppose that this invalid request caused the problem (more like a guess, really). If you think there's a way I can help reproduce/trigger and fix this bug, please let me know, since the production machine is down until I can ensure my bosses that this particular crash won't happen again.

You only get page faults and valid cr2 for canonical addresses (17 high order bits all equal). In this case rax+0xb0 is not a canonical address, so you got a general protection fault instead, with cr2 unchanged.

I'm trying to understand the network code to see if I can help track this down... So I looked at the code of tcp_recvmsg, and I saw that the function that calls __kfree_skb is sk_eat_skb, which is called in tcp_recvmsg: if (tcp_hdr(skb)->fin) goto found_fin_ok; if (!(flags & MSG_PEEK)) { sk_eat_skb(sk, skb, copied_early); copied_early = 0; } continue; found_fin_ok: /* Process the FIN. */ ++*seq; if (!(flags & MSG_PEEK)) { sk_eat_skb(sk, skb, copied_early); copied_early = 0; } break; Now, I'm no kernel programmer, but I saw the "Process the FIN" thing on the code. I'm tuning these proc parameters....maybe some of these are triggering the bug?

I'm sorry, this is not right. The production machine has 16GB of RAM.
Don't know if that matters regarding those proc parameters, though.

So something overwrote sk->sk_prot pointer (or skb->sk pointer) with some data. tcp sockets are allocated from a dedicated kmem_cache (because of SLAB_DESTROY_RCU attribute). Their sk->sk_prot should never change in normal operation, since underlying memory cannot be reused by another object type in kernel. It should be NULL or &tcp_prot Felipe, please describe your configuration as much as possible.

If you want this problem to be solved, its important to setup in your lab a workload to trigger again and again the bug, in order to provide us more crash information.

I've been running non-stop since the first bug happened, but so far the problem hasn't surfaced again :-( I've been using the kernel with the patch that you provided me (nf_tproxy.c).

Is there a chance that patch fixed the problem? This is a real bug, but I dont think it can fix your problem. Looking again at your crash, we see RCX=0x720, decimal 1824 As its skb->len, we are freeing an skb that was collapsed or something like that, since 1824 > 1460 (the normal MSS on ethernet) GRO is off on your machine. But coincidently 0x0720 is also a blank char for VGA screen... (0x20 : ASCII space, 0x07 : default attribute) So maybe you hit a corruption outside of network stack. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I can, but my bosses will kick my ass if I bring down the ISP again :) If you think it's the only way to find the problem I'll tell them that I need to do it. In this case, please tell me what other config options/tools I can use to get as much info as possible...since I'll probably be able to test this only once more on the production environment for debugging purposes.

The thing is: The ISP is a 200Mbps network with 10,000 users. The first time it took around 2 minutes to trigger the bug. The second time it took around 17 minutes. So I *think* it's some TCP flag with some weird content...but I can't find out what it is so I can trigger it on the lab. So my only guess is to enable every possible debug flag I can think of to track the bug down on the production environment. Any hints here would be appreciated :) Cheers, Felipe Damasio -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Any hints here > would be appreciated :) Is it possible for you to mirror the production traffic to another port, and then do a tcpdump capture to a series of files, so that you might possibly be able to correlate the kernel crash to the actual packets on the wire (and the Invalid Request squid errors)?

I don't see anything preventing use of timewait sockets, so the patch looks correct to me. Applied to nf-2.6.git, thanks Eric. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
