Jason Ish e87d4f8a28 Split the defrag counters into ipv4 and ipv6. 16 years ago
Jason Ish 6b562f7aa6 Issue 82 - fragment counters. - number of fragments - number reassembled - number of timeouts 16 years ago
Pablo Rincon d0404d8447 Renaming errors with naming conventions 16 years ago
Pablo Rincon ad2c136e8f Renaming errors (naming conventions) 16 years ago
Jason Ish 8f618b2121 - actually re-inject ipv6 re-assembled packets. - set the next header. 16 years ago
Jason Ish fbf03a927d Fix issue 71. The insert and re-assemble need to be done under the same tracker lock. 16 years ago
Jason Ish 7d920a1254 Fix issue 65. 
- Update unit test to trigger the failure found in the issue 65 pcap.
- Increase pkt buffer to account for the IPv6 header, as a maximum
  size IPv6 datagram is 40 + 0xffff.
- Account for IPv4 header when checking where end of fragment lies.
- Second sanity check during re-assembly to check for writing past
  the end of the pkt buffer.

Steve Grubb c95cd2e80a memory leak cleanups in misc places 
Hello,

This is all the rest of the memory leaks I found.

*In src/source-pcap-file.c at line 152, ptv is not being freed.
*In src/util-unittest-helper.c at line 152, p was not being freed.
*In src/log-httplog.c at line 195, aft was not being freed
*In src/counters.c at line 51, log_filename was not being freed. At line 1188
pctx is being tested to see if its NULL. However, at 1173 it exits the
function if it were NULL. This test is not needed and should be deleted.
*In src/defrag.c at line 351, tracker was not being freed. At line 390, dc is
being checked for NULL but this was already done at line 384. Probably what
was meant was checking the value of dc->frag_table which was just assigned.

The patch below makes the above described changes.

Jason Ish 5076452707 Potential fix for issue 60. 
- Increase the packet buffer so it can hold the link header when we
  have maximum size IP datagrams.
- Fix ip header length and pkt length calculation for re-assembled
  packets.

Jason Ish c4f178f3d7 Do not seen_last unless the packet with more_frags=0 was actually inserted into the frag tracker. Fixes issue 53. 
Add unit test for this failure case.
