netfilter bug?? Begin forwarded message: Date: Tue, 28 Jun 2005 05:36:12 -0400 (EDT) From: Justin Piszcz <jpiszcz@xxxxxxxxxxxxxxx> To: linux-kernel@xxxxxxxxxxxxxxx Subject: Packet of death w/NFS+ULOGD+XFS under Kernel 2.6.x? The following e-mail is related to the previous thread: http://www.uwsg.iu.edu/hypermail/linux/kernel/0506.2/0067.html Recently, I was copying some images I scanned in (a good 300MB or so) with the following command: cp -r images /remote/disk2/share It caused the _SAME_ lockup as my dd problems. The weird part is as follows, once the box locks up (the remote host I am sending the images to), I reboot and when sets the IP interfaces up, the client machine (which the images) is still sending it some kind of 'death' packet, as you can see below: May 14 08:51:27 localhost kernel: ipt_ULOG: error during NLMSG_PUT I get a few of these messages and then the kernel/console freezes up. It is not until I reboot or shutoff the client machine that the server can come up. I actually thought it might be a ulogd issue, I tried removing all of the ulogd rules from my FWALL but still had freezing issues. Has anyone had similar problems? Syslog bootup & crash below: May 14 08:51:26 localhost kernel: e100: eth1: e100_watchdog: link up, 100Mbps, full-duplex May 14 08:51:26 localhost kernel: e100: eth2: e100_watchdog: link up, 100Mbps, full-duplex May 14 08:51:26 localhost kernel: ipt_ULOG: error during NLMSG_PUT May 14 08:51:26 localhost kernel: ipt_ULOG: Error building netlink message May 14 08:51:26 localhost kernel: nfs warning: mount version older than kernel May 14 08:51:26 localhost last message repeated 4 times May 14 08:51:27 localhost kernel: process `named' is using obsolete setsockopt SO_BSDCOMPAT May 14 08:51:27 localhost kernel: ipt_ULOG: error during NLMSG_PUT May 14 08:51:27 localhost kernel: ipt_ULOG: Error building netlink message May 14 08:51:27 localhost kernel: ipt_ULOG: error during NLMSG_PUT May 14 08:51:27 localhost kernel: ipt_ULOG: Error building netlink message May 14 08:51:29 localhost kernel: ipt_ULOG: error during NLMSG_PUT May 14 08:51:29 localhost kernel: ipt_ULOG: Error building netlink message ^^ Once it gets to this point the console is locked hard, nothing will fix except a reboot or shutdown. ^^^ Also, until the other machine is shut off, rebooted or simply disconnected from the network, this one will not boot. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
