Wireshark · Wireshark-dev: Re: [Wireshark-dev] [Wireshark-commits] rev 48227: /trunk/epan/ /trunk/epan/dissectors/: packet-tcp.

[Evan Huus <eapache@xxxxxxxxx>]

Of possible interest: this change exposed a fairly significant memory
leak in the TCP dissector.

==31545== 233,960 (172,560 direct, 61,400 indirect) bytes in 4,314
blocks are definitely lost in loss record 31,667 of 31,670
==31545==    at 0x4C2CD7B: malloc (in
/usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)
==31545==    by 0x9290CD0: g_malloc (gmem.c:159)
==31545==    by 0x92A5EE2: g_slice_alloc (gslice.c:1003)
==31545==    by 0x69D7B9B: dissect_tcp (packet-tcp.c:1121)
==31545==    by 0x637EF27: call_dissector_through_handle (packet.c:458)
==31545==    by 0x637F74C: call_dissector_work (packet.c:549)
==31545==    by 0x637FF9F: dissector_try_uint_new (packet.c:966)
==31545==    by 0x637FFF6: dissector_try_uint (packet.c:992)
==31545==    by 0x66FF6BF: dissect_ip (packet-ip.c:2413)
==31545==    by 0x637EF27: call_dissector_through_handle (packet.c:458)
==31545==    by 0x637F74C: call_dissector_work (packet.c:549)
==31545==    by 0x637FF9F: dissector_try_uint_new (packet.c:966)

Don't have time to look for a while, so if someone who knows the TCP
dissector wants to fix it, be my guest :)
