https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=240609 Bug ID: 240609 Summary: [iflib] [panic] with INVARIANTS: sleeping in an epoch section (12.1-pre-QA) (vlan + lagg involved) Product: Base System Version: 12.0-STABLE Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: bugzilla.freebsd@omnilan.de Hello, here's a iflib related panic I get on my real-world cold-standby setup with 12.1-prerelease and debug kernel. It happens when creating a vlan(4) child with if_igb(4) pair as lagg(4) parent: <6>vlan0: link state changed to UP panic: sleeping in an epoch section cpuid = 1 time = 1568620268 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe000058b380 vpanic() at vpanic+0x19d/frame 0xfffffe000058b3d0 panic() at panic+0x43/frame 0xfffffe000058b430 _sleep() at _sleep+0x466/frame 0xfffffe000058b4d0 pause_sbt() at pause_sbt+0x10f/frame 0xfffffe000058b510 e1000_reset_hw_82580() at e1000_reset_hw_82580+0x1cc/frame 0xfffffe000058b550 em_if_stop() at em_if_stop+0x1b/frame 0xfffffe000058b570 iflib_stop() at iflib_stop+0xc3/frame 0xfffffe000058b5c0 iflib_vlan_register() at iflib_vlan_register+0xad/frame 0xfffffe000058b600 lagg_register_vlan() at lagg_register_vlan+0xda/frame 0xfffffe000058b660 vlan_config() at vlan_config+0x50b/frame 0xfffffe000058b6c0 vlan_clone_create() at vlan_clone_create+0x29b/frame 0xfffffe000058b730 if_clone_createif() at if_clone_createif+0x4a/frame 0xfffffe000058b780 ifioctl() at ifioctl+0x6fe/frame 0xfffffe000058b850 kern_ioctl() at kern_ioctl+0x2b0/frame 0xfffffe000058b8b0 sys_ioctl() at sys_ioctl+0x15d/frame 0xfffffe000058b980 amd64_syscall() at amd64_syscall+0x276/frame 0xfffffe000058bab0 fast_syscall_common() at fast_syscall_common+0x101/frame 0xfffffe000058bab0 --- syscall (54, FreeBSD ELF64, sys_ioctl), rip = 0x80047439a, rsp = 0x7fffffffe348, rbp = 0x7fffffffe350 --- KDB: enter: panic #9 0xffffffff805cf4ca in vpanic (fmt=<value optimized out>, ap=<value optimized out>) at /usr/local/share/deploy-tools/RELENG_12/src/sys/kern/kern_shutdown.c:866 #10 0xffffffff805cf273 in panic (fmt=<value optimized out>) at /usr/local/share/deploy-tools/RELENG_12/src/sys/kern/kern_shutdown.c:804 #11 0xffffffff805da0b6 in _sleep (ident=0xffffffff80ef0941, lock=0x0, priority=0, wmesg=<value optimized out>, sbt=42949672, pr=0, flags=256) at /usr/local/share/deploy-tools/RELENG_12/src/sys/kern/kern_synch.c:150 #12 0xffffffff805da4af in pause_sbt (wmesg=<value optimized out>, sbt=42949672, pr=<value optimized out>, flags=<value optimized out>) at /usr/local/share/deploy-tools/RELENG_12/src/sys/kern/kern_synch.c:332 #13 0xffffffff81b3e7cc in e1000_reset_hw_82580 (hw=0xfffffe004b7eb008) at RELENG_12/src/sys/dev/e1000/e1000_osdep.h:97 #14 0xffffffff81b0c86b in em_if_stop (ctx=<value optimized out>) at /usr/local/share/deploy-tools/RELENG_12/src/sys/dev/e1000/if_em.c:1867 #15 0xffffffff806f74f3 in iflib_stop (ctx=0xfffff8000291f800) at ifdi_if.h:268 #16 0xffffffff80704e3d in iflib_vlan_register (arg=0xfffff8000291f800, ifp=0xfffff8000295a800, vtag=232) at /usr/local/share/deploy-tools/RELENG_12/src/sys/net/iflib.c:3883 #17 0xffffffff806eb94a in lagg_register_vlan (arg=<value optimized out>, ifp=<value optimized out>, vtag=<value optimized out>) at /usr/local/share/deploy-tools/RELENG_12/src/sys/net/if_lagg.c:452 #18 0xffffffff806f68fb in vlan_config (ifv=0xfffff80002555c00, p=0xfffff80002895000, vid=<value optimized out>) at /usr/local/share/deploy-tools/RELENG_12/src/sys/net/if_vlan.c:1431 #19 0xffffffff806f596b in vlan_clone_create (ifc=0xfffff800024dec00, name=0xfffffe000058b8d0 "vlan0", len=18446735277655190528, params=<value optimized out>) at /usr/local/share/deploy-tools/RELENG_12/src/sys/net/if_vlan.c:1066 #20 0xffffffff806e1c3a in if_clone_createif (ifc=0xfffff800024dec00, name=0xfffffe000058b8d0 "vlan0", len=16, params=0x22db40 <Address 0x22db40 out of bounds>) at /usr/local/share/deploy-tools/RELENG_12/src/sys/net/if_clone.c:229 #21 0xffffffff806d90be in ifioctl (so=<value optimized out>, cmd=3223349628, data=0xfffffe000058b8d0 "vlan0", td=0xfffff800037a55e0) at /usr/local/share/deploy-tools/RELENG_12/src/sys/net/if.c:3097 ---Type <return> to continue, or q <return> to quit--- #22 0xffffffff8063d870 in kern_ioctl (td=0xfffff800037a55e0, fd=<value optimized out>, com=3223349628, data=<value optimized out>) at RELENG_12/src/sys/sys/file.h:337 #23 0xffffffff8063d54d in sys_ioctl (td=0xfffff800037a55e0, uap=0xfffff800037a59a0) at /usr/local/share/deploy-tools/RELENG_12/src/sys/kern/sys_generic.c:712 #24 0xffffffff8093abe6 in amd64_syscall (td=0xfffff800037a55e0, traced=0) at RELENG_12/src/sys/amd64/amd64/../../kern/subr_syscall.c:135 #25 0xffffffff80912550 in fast_syscall_common () at /usr/local/share/deploy-tools/RELENG_12/src/sys/amd64/amd64/exception.S:581 #26 0x000000080047439a in ??
