--- Comment #15 from takahiro.kuros...@gmail.com --- Created attachment 259236 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=259236&action=edit testcase to reproduce the similar panic I've been able to reproduce a similar panic with the attached patch for /usr/tests/sys/net/if_ovpn/if_ovpn. The testcase uses a broadcast packet for the openvpn port that needs m_copym() calls to deliver it to each socket. m_copym() increases reference counts of mbuf clusters that results in m_unshare() returning a new mbuf and dropping M_PKTHDR of the original mbuf. To reproduce the panic: ---- cd /usr/tests/sys/net cp -pr if_ovpn if_ovpn.283426 cd if_ovpn.283426 patch -p1 < /path/to/repro-283426.diff kldload if_epair if_bridge if_ovpn sync; sync; sync kyua debug if_ovpn:bz283426 ---- -- You are receiving this mail because: You are the assignee for the bug.
