https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D231428 Bug ID: 231428 Summary: 12.0-ALPHA6 crashes with gif (IPv4 in IPv4) over vtnet Product: Base System Version: CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: lev@FreeBSD.org I have very fresh 12.0-ALPHA6/r338707 installed as VierualBox guest with vtnet(8) virtual NIC which is bridged with host NIC. I'm creating gif-based tubbel to other FreeBSD system with standard mantra: #ifconfig gif0 create <my-int> <his-int> #ifconfig gif0 tunnel <my-ext> <his-ext> After that "ping <his-int>" works, but when I run "iperf3 -c <his-int>" on this ALPHA6 (with "iperf -s" running on other host) system crashes immediat= ely: anic: Assertion !in_epoch(net_epoch_preempt) && !mtx_owned(&(&(tcbinfo))->ipi_lock) failed at /data/src/sys/netinet/tcp_input.c:803 cpuid =3D 0 time =3D 1537187018 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe000044a310 vpanic() at vpanic+0x1a3/frame 0xfffffe000044a370 panic() at panic+0x43/frame 0xfffffe000044a3d0 tcp_input() at tcp_input+0x16a9/frame 0xfffffe000044a520 ip_input() at ip_input+0x126/frame 0xfffffe000044a5a0 netisr_dispatch_src() at netisr_dispatch_src+0x83/frame 0xfffffe000044a600 gif_input() at gif_input+0x2db/frame 0xfffffe000044a640 in_gif_input() at in_gif_input+0x73/frame 0xfffffe000044a680 encap_input() at encap_input+0x1cf/frame 0xfffffe000044a6f0 encap4_input() at encap4_input+0x28/frame 0xfffffe000044a720 ip_input() at ip_input+0x126/frame 0xfffffe000044a7a0 netisr_dispatch_src() at netisr_dispatch_src+0x83/frame 0xfffffe000044a800 ether_demux() at ether_demux+0x15e/frame 0xfffffe000044a830 ether_nh_input() at ether_nh_input+0x373/frame 0xfffffe000044a880 netisr_dispatch_src() at netisr_dispatch_src+0x83/frame 0xfffffe000044a8e0 ether_input() at ether_input+0x42/frame 0xfffffe000044a900 vtnet_rxq_eof() at vtnet_rxq_eof+0x736/frame 0xfffffe000044a9a0 vtnet_rx_vq_intr() at vtnet_rx_vq_intr+0x58/frame 0xfffffe000044a9d0 vtpci_legacy_intr() at vtpci_legacy_intr+0xb0/frame 0xfffffe000044aa10 ithread_loop() at ithread_loop+0x140/frame 0xfffffe000044aa70 fork_exit() at fork_exit+0x84/frame 0xfffffe000044aab0 fork_trampoline() at fork_trampoline+0xe/frame 0xfffffe000044aab0 It is 100% reproducible for me. --=20 You are receiving this mail because: You are the assignee for the bug.=
