The condition "> H323_ERROR_STOP" can never be true since H323_ERROR_STOP is positive and is the highest possible return code, while real errors are negative, fix the checks. Also only abort on real errors in some spots that were just interpreting any return value != 0 as error. Fixes crashes caused by use of stale data after a parsing error occured: BUG: unable to handle kernel paging request at virtual address bfffffff printing eip: c01aa0f8 *pde = 1a801067 *pte = 00000000 Oops: 0000 [#1] PREEMPT Modules linked in: ip_nat_h323 ip_conntrack_h323 nfsd exportfs sch_sfq sch_red cls_fw sch_hfsc xt_length ipt_owner xt_MARK iptable_mangle nfs lockd sunrpc pppoe pppoxx CPU: 0 EIP: 0060:[<c01aa0f8>] Not tainted VLI EFLAGS: 00210646 (2.6.17-rc4 #8) EIP is at memmove+0x19/0x22 eax: d77264e9 ebx: d77264e9 ecx: e88d9b17 edx: d77264e9 esi: bfffffff edi: bfffffff ebp: de6a7680 esp: c0349db8 ds: 007b es: 007b ss: 0068 Process asterisk (pid: 3765, threadinfo=c0349000 task=da068540) Stack: <0>00000006 c0349e5e d77264e3 e09a2b4e e09a38a0 d7726052 d7726124 00000491 00000006 00000006 00000006 00000491 de6a7680 d772601e d7726032 c0349f74 e09a2dc2 00000006 c0349e5e 00000006 00000000 d76dda28 00000491 c0349f74 Call Trace: [<e09a2b4e>] mangle_contents+0x62/0xfe [ip_nat] [<e09a2dc2>] ip_nat_mangle_tcp_packet+0xa1/0x191 [ip_nat] [<e0a2712d>] set_addr+0x74/0x14c [ip_nat_h323] [<e0ad531e>] process_setup+0x11b/0x29e [ip_conntrack_h323] [<e0ad534f>] process_setup+0x14c/0x29e [ip_conntrack_h323] [<e0ad57bd>] process_q931+0x3c/0x142 [ip_conntrack_h323] [<e0ad5dff>] q931_help+0xe0/0x144 [ip_conntrack_h323] ...
