https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=254015 Bug ID: 254015 Summary: [if_bridge] Panic when using bridge interface on 13.0-BETA4 Product: Base System Version: 13.0-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: shamaz.mazum@gmail.com Hi! I am on commit 20f9e2a723f5f560d6219e28f36dd3b8f8561b3a. My installation uses bridge interface which connects wired and wireless interfaces. After ~30 seconds of uptime, FreeBSD panics. Backtrace seems like nonsense to me. Here m != NULL and in the next frame (in m_dup()) m == NULL. WTF?) (kgdb) frame 9 #9 0xffffffff80c8ed6a in m_dup (m=0x0, how=<optimized out>, how@entry=1) at /usr/src/sys/kern/uipc_mbuf.c:686 686 remain = m->m_pkthdr.len; (kgdb) frame 10 #10 0xffffffff82c249d2 in bridge_broadcast (sc=sc@entry=0xfffff8001362a800, src_if=src_if@entry=0xfffff80010a57800, m=0xfffff8002cdbe200, m@entry=0xfffff80003a0ea00, runfilt=runfilt@entry=0) at /usr/src/sys/net/if_bridge.c:2587 2587 mc = m_dup(m, M_NOWAIT); (kgdb) print m $1 = (struct mbuf *) 0xfffff8002cdbe200 Here is saved core + kernel.full (~50Mb compressed, 1Gb uncompressed). https://drive.google.com/file/d/1O8zmuUuDjRnjcwdBxT7YNH0f-_r6j862/view?usp=sharing Please, share your thoughts how to fix this. -- You are receiving this mail because: You are the assignee for the bug.help
