Created attachment 808582 [details] kernel panic Description of problem: Intel Atom 2500CCE acting as router. Linux blah 3.11.2-201.fc19.x86_64 #1 SMP Fri Sep 27 19:20:55 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux LAN device em0 WAN device p13p1 MTU 1500 IPv4 ISP connection using PPPOE (ppp0) via p13p1 MTU 1492 IPv6 SIT (rdhe0) over ppp0 MTU 1480 IPv6 prefix delegated for local clients. When a local client attempts to send an IPv6 packet larger than the MTU, the kernel on the router panics. In normal operation this shouldn't happen but a simple 'ping6 -s 1490 www.google.com' from a client will trigger the panic. If you try this from the router itself, you get 'Packet too big: mtu=1472' but no panic suggesting this is a 'forward' issue. Version-Release number of selected component (if applicable): kernel-3.11.2-201.fc19.x86_64 How reproducible: 'ping6 -s 1490 www.google.com' from a client will reproduce every time. Steps to Reproduce: 1. Set up a pppoe connection 2. Set up a 6rd SIT tunnel over the pppoe connection 3. Set up infrastructure to distribute delegated IPv6 addresses 4. From a client run 'ping6 -s 1490 www.google.com' Actual results: Kernel panic on router. Expected results: Client should receive 'Packet too big: mtu=1472' but the router's kernel should NOT panic at the attempt. Additional info: I thought this might have been related to trying kernel mode pppoe but the panic happens even if using the rp-pppoe daemon.
Hi George, could you please give us the full output of "ip a" here? Thanks, Michele

Hi. It seems i also did hit this bug. Or something similar - my setup is somewhat different. Machine is used as internet gateway, and it uses pppoe (kernel mode) for uplink.

Regards, H.
Hrvoje, George, I've discussed this a bit upstream. Since you can reproduce it 100%, can you try the following kernel: http://koji.fedoraproject.org/koji/buildinfo?buildID=478832 It has the following two commits: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9037c3579a277f3a23ba476664629fda8c35f7c4 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=6aafeef03b9d9ecf255f3a80ed85ee070260e1ae which might be relevant here. If you could let me know if they work or not that'd be great. Thanks, Michele
Hi. It seems that this fixes the problem. To be precise, i'm unable to trigger panic, and it seems that neworking stack is correctly handling packet-too-big situation. # ping6 -s 2000 x:x:fffd::2 PING x:x:fffd::2(x:x:fffd::2) 2000 data bytes From x:x:7161:630::1 icmp_seq=1 Packet too big: mtu=1492 2008 bytes from x:x:fffd::2: icmp_seq=3 ttl=59 time=7.10 ms 2008 bytes from x:x:fffd::2: icmp_seq=4 ttl=59 time=9.20 ms 2008 bytes from x:x:fffd::2: icmp_seq=5 ttl=59 time=7.05 ms 2008 bytes from x:x:fffd::2: icmp_seq=6 ttl=59 time=7.47 ms 2008 bytes from x:x:fffd::2: icmp_seq=7 ttl=59 time=7.61 ms 2008 bytes from x:x:fffd::2: icmp_seq=8 ttl=59 time=6.72 ms ^C --- x:x:fffd::2 ping statistics --- 8 packets transmitted, 6 received, +1 errors, 25% packet loss, time 7019ms rtt min/avg/max/mdev = 6.725/7.529/9.200/0.806 ms # Dmesg: [ 0.000000] Initializing cgroup subsys cpuset [ 0.000000] Initializing cgroup subsys cpu [ 0.000000] Initializing cgroup subsys cpuacct [ 0.000000] Linux version 3.13.0-0.rc0.git5.1.fc21.x86_64 (mockbuild@bkernel02) (gcc version 4.8.2 20131111 (Red Hat 4.8.2-4) (GCC) ) #1 SMP Sat Nov 16 16:09:55 UTC 2013 [ 0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-3.13.0-0.rc0.git5.1.fc21.x86_64 root=UUID=bd0a2380-7b31-401a-aeed-56cf79d500ed ro nomodeset rd.md=0 rd.lvm=0 rd.dm=0 vconsole.keymap=us rd.luks=0 vconsole.font=latarcyrheb-sun16 console=tty0 console=ttyS1 LANG=en_US.UTF-8 [ 0.000000] e820: BIOS-provided physical RAM map: [ 0.000000] BIOS-e820: [mem 0x0000000000000000-0x000000000009abff] usable [ 0.000000] BIOS-e820: [mem 0x000000000009ac00-0x000000000009ffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000000e0000-0x00000000000fffff] reserved [ 0.000000] BIOS-e820: [mem 0x0000000000100000-0x000000001fffffff] usable [ 0.000000] BIOS-e820: [mem 0x0000000020000000-0x00000000201fffff] reserved [ 0.000000] BIOS-e820: [mem 0x0000000020200000-0x000000003fffffff] usable [ 0.000000] BIOS-e820: [mem 0x0000000040000000-0x00000000401fffff] reserved [ 0.000000] BIOS-e820: [mem 0x0000000040200000-0x00000000bc557fff] usable [ 0.000000] BIOS-e820: [mem 0x00000000bc558000-0x00000000bc560fff] ACPI data [ 0.000000] BIOS-e820: [mem 0x00000000bc561000-0x00000000bc5aafff] ACPI NVS [ 0.000000] BIOS-e820: [mem 0x00000000bc5ab000-0x00000000bc5b2fff] usable [ 0.000000] BIOS-e820: [mem 0x00000000bc5b3000-0x00000000bc8c4fff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000bc8c5000-0x00000000bc8c5fff] usable [ 0.000000] BIOS-e820: [mem 0x00000000bc8c6000-0x00000000bc8d5fff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000bc8d6000-0x00000000bc8f4fff] ACPI NVS [ 0.000000] BIOS-e820: [mem 0x00000000bc8f5000-0x00000000bc918fff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000bc919000-0x00000000bc95bfff] ACPI NVS [ 0.000000] BIOS-e820: [mem 0x00000000bc95c000-0x00000000bcb7bfff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000bcb7c000-0x00000000bccfffff] usable [ 0.000000] BIOS-e820: [mem 0x00000000bcd00000-0x00000000bcffffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000bd800000-0x00000000bf9fffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000fed1c000-0x00000000fed3ffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000ff000000-0x00000000ffffffff] reserved [ 0.000000] BIOS-e820: [mem 0x0000000100000000-0x000000013e5fffff] usable [ 0.000000] NX (Execute Disable) protection: active [ 0.000000] SMBIOS 2.6 present.

Hi Hrvoje, perfect thanks. In order to make sure that we narrow the cause, I've built a 3.11.8 fc19 kernel with the two commits mentioned in c#5 (I had to make some changes as it would not apply cleanly). Could you please give it a test and confirm that the issue is still not present? If you'll confirm then we know that the two commits (or one of them) fixes the issue and I'll discuss with upstream if we can bring it to stable. You can find the whole thing here: http://acksyn.org/files/tmp/bz1015905/ Thanks, Michele
Hi Michele, As a baseline, I made sure the bug was reproducable in 3.11.7-200, which it is. I can also confirm that the problem is fixed in your 3.11.8-200 build. Thanks for tracking this down!
Hi Michele. I can also confirm that this kernel fixes issue for me. No more kernel panic, and packet-to-big is correctly returned. Please notify us when this enters regular F19 kernel. Thank you. Regards, H.
Hi Georhe and Hrvoje, thanks for testing. Just so I can make sure which is the single patch fixing your scenario and propose it for stable, can you please let me know which of the two following kernels works and which one does not work? http://acksyn.org/files/tmp/1/ and http://acksyn.org/files/tmp/2/ Once I know which of the two patches fixes this scenario I can proceed. Thanks again, Michele
Version 1 didn't fix the problem but version 2 did.
Thanks a lot George, much appreciated. I've asked for -stable inclusion. I'll keep you posted here once it trickles down. Fedora kernel folks, if you want to include the 3.11.x patch before that, I've put it here: http://acksyn.org/files/patches/0002-netfilter-push-reasm-skb-through-instead-of-original.patch regards, MIchele
Discussed this more upstream and it makes more sense to have both patches in: 9037c3579a277f3a23ba476664629fda8c35f7c4 "ip6_output: fragment outgoing reassembled skb properly" 6aafeef03b9d9ecf255f3a80ed85ee070260e1ae "netfilter: push reasm skb through instead of original frag skbs" The first one applies cleanly to 3.11.x the second one needs a bit of massaging (see c#12)
Thanks Michele! Much appreciated. Added to git.
