https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D230950 Bug ID: 230950 Summary: UDP6 panics after r338306 Product: Base System Version: CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Many People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: sbruno@FreeBSD.org CC: bz@FreeBSD.org I'm not 100% sure that these panics are from r338306. They are from an ftp mirror and pkg mirror, both induced from unbound doing its ipv6 udp thing. ----------- Fatal trap 12: page fault while in kernel mode cpuid =3D 4; apic id =3D 32 fault virtual address =3D 0x68 fault code =3D supervisor read data, page not present instruction pointer =3D 0x20:0xffffffff80a5380b stack pointer =3D 0x28:0xfffffe0141068500 frame pointer =3D 0x28:0xfffffe0141068750 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 38582 (unbound) [ thread pid 38582 tid 100859 ] Stopped at ip6_output+0x18db: movq ll+0x47(%rcx),%rcx db> bt Tracing pid 38582 tid 100859 td 0xfffff8010988b000 ip6_output() at ip6_output+0x18db/frame 0xfffffe0141068750 udp6_send() at udp6_send+0x7f8/frame 0xfffffe0141068910 sosend_dgram() at sosend_dgram+0x33b/frame 0xfffffe0141068980 kern_sendit() at kern_sendit+0x237/frame 0xfffffe0141068a20 sendit() at sendit+0x19e/frame 0xfffffe0141068a70 sys_sendto() at sys_sendto+0x4d/frame 0xfffffe0141068ac0 amd64_syscall() at amd64_syscall+0x369/frame 0xfffffe0141068bf0 fast_syscall_common() at fast_syscall_common+0x101/frame 0xfffffe0141068bf0 --- syscall (133, FreeBSD ELF64, sys_sendto), rip =3D 0x800836efa, rsp =3D 0x7fffdf9fa988, rbp =3D 0x7fffdf9fa9d0 --- -------- Fatal trap 12: page fault while in kernel mode cpuid =3D 2; apic id =3D 02 fault virtual address =3D 0x7c fault code =3D supervisor read data, page not present instruction pointer =3D 0x20:0xffffffff80a4d344 stack pointer =3D 0x28:0xfffffe0094a36490 frame pointer =3D 0x28:0xfffffe0094a364d0 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 1247 (unbound) [ thread pid 1247 tid 100907 ] Stopped at selectroute+0x194: movl ll+0x5b(%rdi),%eax db>=20 db> bt Tracing pid 1247 tid 100907 td 0xfffff8000d131580 selectroute() at selectroute+0x194/frame 0xfffffe0094a364d0 in6_selectroute_fib() at in6_selectroute_fib+0xf/frame 0xfffffe0094a364f0 ip6_output() at ip6_output+0xfc4/frame 0xfffffe0094a36750 udp6_send() at udp6_send+0x7f8/frame 0xfffffe0094a36910 sosend_dgram() at sosend_dgram+0x33b/frame 0xfffffe0094a36980 kern_sendit() at kern_sendit+0x237/frame 0xfffffe0094a36a20 sendit() at sendit+0x19e/frame 0xfffffe0094a36a70 sys_sendto() at sys_sendto+0x4d/frame 0xfffffe0094a36ac0 amd64_syscall() at amd64_syscall+0x369/frame 0xfffffe0094a36bf0 fast_syscall_common() at fast_syscall_common+0x101/frame 0xfffffe0094a36bf0 --- syscall (133, FreeBSD ELF64, sys_sendto), rip =3D 0x800836efa, rsp =3D 0x7fffdfdfcce8, rbp =3D 0x7fffdfdfcd30 --- --=20 You are receiving this mail because: You are the assignee for the bug.=
