------==--bound.126199.webmail15.yandex.ru Content-Transfer-Encoding: 7bit Content-Type: text/plain Hi, I got a trace for this fault. dummynet reinject packet to the ip_input through netisr_dispath. This procedure was done success several times, but in the next time it's fault. (kgdb) p &ipfw_chk $1 = (int (*)(struct ip_fw_args *)) 0xc3374ea0 <ipfw_chk> (kgdb) l *(0xc3374ea0+0x16) 0xc3374eb6 is in ipfw_chk (/usr/src/sys/modules/ipfw/../../netinet/ip_fw2.c:2304). 2299 * ip is the beginning of the ip(4 or 6) header. 2300 * Calculated by adding the L3offset to the start of data. 2301 * (Until we start using L3offset, the packet is 2302 * supposed to start with the ip header). 2303 */ 2304 struct mbuf *m = args->m; 2305 struct ip *ip = mtod(m, struct ip *); 2306 2307 /* 2308 * For rules which contain uid/gid or jail constraints, cache I don't understand why we have panic here.. Can someone explain this panic? -- WBR, Andrey V.
