The webmail client of hotmail did remove a lot of newlines. So here is the hopefully readable mail again from my gmail Account. According to the maintainer list and the document "REPORTING-BUGS" I should send this report to you. Please excuse me, if you are the wrong person to receive this mail. 1. PROBLEM: System call 'sendmsg' of process ospfd (quagga) causes kernel oops 2. I have a setup with two gateways connected with ipsec and gre tunnels. They do ospf routing. This is the setup I have: [ host chgut11fw01 ] ================================================== [ host chgut1fw01 ]     (dev gAAchgut1) 10.254.11.1 ---------gre/ospf--------- 10.254.1.11 (dev gAAchgut11)                       V                                      V          (dev eth1) 10.10.111.4 -----strongswan/ipsec----- 10.10.101.4 (dev eth1) Sometimes, if the process ospfd (package quagga) is trying to send a multicast packet with the system call "sendmsg" a kernel oops happens. When I add and remove the GRE interface in a loop the oops happens normally after some seconds or two, three minutes (this is the way I can reproduce the problem). But the problem happens only on host chgut11fw01 (See hardware details below). On host chgut1fw01 I'm not able to reproduce it! It is the call sendmsg() in ospf_packet.c line 737 (quagga-0.99.20 source) which causes the problem. It tries to send a packet of length 16384 to 224.0.0.5 over device gAAchgut1 as soon as the device is added to the multcast group. 3. Keywords: networking, kernel 4.1 Kernel Version: Linux version 3.0.4-SMP (root@whiskey) (gcc version 4.4.4 (Gentoo 4.4.4-r2 p1.3, pie-0.4.5) ) #1 SMP Thu Oct 6 16:24:22 CEST 2011 4.2 Kernel Config: If necessary, I can post the enabled configuration options. 5. Kernel Version which doesn't have the bug: None 6. Kernel oops message I saw too late, that my kernel 3.0.4 is "tainted". I don't know why, because the kernel 2.6.35.10 which I use as well is not. The only thing I did was to add the "aufs" patch, but on both kernel versions (is that the reason?). Below you find a oops with the not tainted kernel 2.6.35.10. 2011-10-10 09:32:08 chgut11fw01 kernel: skb_over_panic: text:c1305749 len:64 put:64 head:c7ea6a00 data:c7ea6a50 tail:0xc7ea6a90 end:0xc7ea6a80 dev: 2011-10-10 09:32:08 chgut11fw01 kernel: ------------[ cut here ]------------ 2011-10-10 09:32:09 chgut11fw01 kernel: kernel BUG at net/core/skbuff.c:128! 2011-10-10 09:32:09 chgut11fw01 kernel: invalid opcode: 0000 [#40] SMP 2011-10-10 09:32:09 chgut11fw01 kernel: Modules linked in: nf_conntrack_netlink nfnetlink ip_gre gre authenc xfrm4_mode_transport deflate zlib_deflate ctr twofish_generic twofish_common serpent cryptd aes_i5 86 aes_generic blowfish cast5 cbc ecb rmd160 sha512_generic sha256_generic sha1_generic xfrm_user xfrm4_tunnel tunnel4 ipcomp xfrm_ipcomp esp4 ah4 af_key tun ipt_LOG xt_limit ipt_REJECT xt_state ipt_REDIRECT  ipt_MASQUERADE xt_policy xt_TCPMSS xt_tcpmss xt_tcpudp xt_NOTRACK iptable_filter iptable_nat xt_mark xt_connmark iptable_mangle iptable_raw ip_tables x_tables nf_conntrack_tftp nf_nat_ftp nf_nat nf_conntrac k_ipv4 nf_defrag_ipv4 nf_conntrack_ftp nf_conntrack rtc ppdev parport_pc parport w83792d i2c_dev i2c_i801 i2c_core pl2303 usbserial coretemp hwmon usbhid ohci_hcd uhci_hcd ehci_hcd usbcore e1000 e1000e aufs ata_piix libata 2011-10-10 09:32:09 chgut11fw01 kernel: 2011-10-10 09:32:09 chgut11fw01 kernel: Pid: 17011, comm: ospfd Tainted: G      D     3.0.4-SMP #1    /LakePort 2011-10-10 09:32:09 chgut11fw01 kernel: EIP: 0060:[] EFLAGS: 00210296 CPU: 0 2011-10-10 09:32:09 chgut11fw01 kernel: EIP is at skb_put+0x85/0x90 2011-10-10 09:32:09 chgut11fw01 kernel: EAX: 00000078 EBX: c1305749 ECX: 00200082 EDX: ffffff8b 2011-10-10 09:32:09 chgut11fw01 kernel: ESI: dd6420c0 EDI: 00000040 EBP: d7d23c7c ESP: d7d23c54 2011-10-10 09:32:09 chgut11fw01 kernel: DS: 007b ES: 007b FS: 00d8 GS: 0033 SS: 0068 2011-10-10 09:32:09 chgut11fw01 kernel: Process ospfd (pid: 17011, ti=d7d22000 task=de908a90 task.ti=d7d22000) 2011-10-10 09:32:09 chgut11fw01 kernel: Stack: 2011-10-10 09:32:09 chgut11fw01 kernel: c13fd19c c1305749 00000040 00000040 c7ea6a00 c7ea6a50 c7ea6a90 c7ea6a80 2011-10-10 09:32:09 chgut11fw01 kernel: c13fb224 d83d90c0 d7d23d34 c1305749 d7d23d20 02916cfd 4c9e613e 00000001 2011-10-10 09:32:09 chgut11fw01 kernel: 00000001 d7d23ce4 d7d23cc8 00000000 0000e8d5 d7d23ecc caddb300 c7ea6a50 2011-10-10 09:32:09 chgut11fw01 kernel: Call Trace: 2011-10-10 09:32:09 chgut11fw01 kernel: [] ?
