https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D221120 Bug ID: 221120 Summary: [panic] network stack Product: Base System Version: 11.1-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: sdalu@sdalu.com During this last week i've got numerous kernel panic (about 2 or 3 a day). = Just after upgrading to 11.1-release (all packages have also been upgraded), dur= ing this period OVH seemed also to have ipv6 problems.=20=20 Panic just stopped two days ago (ipv6 is also working again at ovh), So I g= uess it was perhaps related to ipv6? Below are 2 crash dump (I can provide the full crash log if requested) ---------------------------------------------------- Fatal trap 12: page fault while in kernel mode cpuid =3D 6; apic id =3D 06 fault virtual address =3D 0x3b8 fault code =3D supervisor read data, page not present instruction pointer =3D 0x20:0xffffffff805213df stack pointer =3D 0x28:0xfffffe085ddfd090 frame pointer =3D 0x28:0xfffffe085ddfd120 code segment =3D base 0x0, limit 0xfffff, type 0x1b =3D DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags =3D interrupt enabled, resume, IOPL =3D 0 current process =3D 971 (ping) trap number =3D 12 panic: page fault cpuid =3D 6 Uptime: 11h52m49s Dumping 1629 out of 32659 MB:..1%..11%..21%..31%..41%..51%..61%..71%..81%..= 91% #0 doadump (textdump=3D<value optimized out>) at pcpu.h:222 222 pcpu.h: No such file or directory. in pcpu.h (kgdb) #0 doadump (textdump=3D<value optimized out>) at pcpu.h:222 #1 0xffffffff805251d1 in kern_reboot (howto=3D260) at /usr/src/sys/kern/kern_shutdown.c:366 #2 0xffffffff80525656 in vpanic (fmt=3D<value optimized out>,=20 ap=3D<value optimized out>) at /usr/src/sys/kern/kern_shutdown.c:759 #3 0xffffffff805254c3 in panic (fmt=3D<value optimized out>) at /usr/src/sys/kern/kern_shutdown.c:690 #4 0xffffffff80810942 in trap_fatal (frame=3D0xfffffe085ddfcfd0, eva=3D952) at /usr/src/sys/amd64/amd64/trap.c:801 #5 0xffffffff80810be0 in trap_pfault (frame=3D0xfffffe085ddfcfd0, usermode= =3D0) at /usr/src/sys/amd64/amd64/trap.c:717 #6 0xffffffff8081018f in trap (frame=3D0xfffffe085ddfcfd0) at /usr/src/sys/amd64/amd64/trap.c:421 #7 0xffffffff807f62e1 in calltrap () at /usr/src/sys/amd64/amd64/exception.S:236 #8 0xffffffff805213df in __rw_wlock_hard (c=3D0xfffff8001d451310,=20 v=3D<value optimized out>, tid=3D18446735279442007392,=20 file=3D<value optimized out>, line=3D<value optimized out>) at /usr/src/sys/kern/kern_rwlock.c:903 #9 0xffffffff806fc5c1 in in6_lltable_lookup (llt=3D<value optimized out>,= =20 flags=3D8192, l3addr=3D<value optimized out>) at /usr/src/sys/netinet6/in6.c:2275 #10 0xffffffff8062baa9 in llentry_alloc (ifp=3D0xfffff8000740c000,=20 lt=3D0xfffff8000790e700, dst=3D0xfffff8001fe84520) at if_llatbl.h:253 #11 0xffffffff8061eda0 in flowtable_lookup_common (ft=3D0xffffffff80d107b8,= =20 key=3D0xfffffe085ddfd280, keylen=3D16, fibnum=3D0) at /usr/src/sys/net/flowtable.c:588 #12 0xffffffff8061e3c5 in flowtable_lookup (sa=3D<value optimized out>,=20 m=3D0xfffff8000bf9d500, ro=3D0xfffffe085ddfd3b8) at /usr/src/sys/net/flowtable.c:395 #13 0xffffffff8070c2ee in ip6_output (m0=3D<value optimized out>,=20 opt=3D<value optimized out>, ro=3D0xfffffe085ddfd3b8, flags=3D0, im6o= =3D0x0,=20 ifpp=3D0xfffffe085ddfd690, inp=3D<value optimized out>) at /usr/src/sys/netinet6/ip6_output.c:506 #14 0xffffffff8071fd7f in rip6_output (m=3D0xfffff8000bf9d500,=20 so=3D0xfffff80033950360) at /usr/src/sys/netinet6/raw_ip6.c:538 #15 0xffffffff80720c24 in rip6_send (so=3D0xfffff80033950360,=20 flags=3D<value optimized out>, m=3D0xfffff8000bf9d500,=20 nam=3D<value optimized out>, control=3D0x0, td=3D<value optimized out>) at /usr/src/sys/netinet6/raw_ip6.c:890 #16 0xffffffff805b0a6c in sosend_generic (so=3D<value optimized out>,=20 addr=3D0xfffff801e9cb5e40, uio=3D<value optimized out>,=20 top=3D<value optimized out>, control=3D<value optimized out>,=20 flags=3D<value optimized out>, td=3D<value optimized out>) at /usr/src/sys/kern/uipc_socket.c:1360 #17 0xffffffff805b7341 in kern_sendit (td=3D<value optimized out>,=20 s=3D<value optimized out>, mp=3D0xfffffe085ddfd8e0, flags=3D0, control= =3D0x0,=20 segflg=3DUIO_USERSPACE) at /usr/src/sys/kern/uipc_syscalls.c:873 #18 0xffffffff805b76a3 in sendit (td=3D0xfffff8006cce9560,=20 s=3D<value optimized out>, mp=3D0xfffffe085ddfd8e0,=20 flags=3D<value optimized out>) at /usr/src/sys/kern/uipc_syscalls.c:793 #19 0xffffffff805b74ed in sys_sendto (td=3D<value optimized out>,=20 uap=3D<value optimized out>) at /usr/src/sys/kern/uipc_syscalls.c:924 #20 0xffffffff808114a4 in amd64_syscall (td=3D0xfffff8006cce9560, traced=3D= 0) at subr_syscall.c:135 #21 0xffffffff807f65cb in Xfast_syscall () at /usr/src/sys/amd64/amd64/exception.S:396 #22 0x000000080130bd3a in ??
