2012-10-12Use seasonal allocation for name resolution. This effectively scrubs ourGerald Combs1-2/+16
resolution information between capture files so that we don't leak host entries from one file to another (e.g. embarassing-host-name.example.com from file1.pcapng into a name resolution block in file2.pcapng). host_name_lookup_cleanup and host_name_lookup_init must now be called after each call to se_free_all. As a result we now end up reading our various name resolution files much more than we should. svn path=/trunk/; revision=45511

when calling it with pattern value of 0 dissector_add_uint() is *not only* used by tcp.port/udp.port dissector tables where 0 is not valid port number, in some dissector tables 0 is valid protocol number, packet type, etc.. Sample dissectors using dissector_add_uint(.pattern = 0): packet-ansi_637.c:2348: dissector_add_uint("ansi_a.sms", 0, ansi_637_trans_handle); packet-cip.c:6017: dissector_add_uint("cip.class.iface", 0, cip_class_generic_handle ); packet-lon.c:723: dissector_add_uint("cnip.protocol", 0, lon_handle); packet-q931.c:3599: dissector_add_uint("lapd.sapi", LAPD_SAPI_Q931 /* 0 */, q931_handle); svn path=/trunk/; revision=44980

2012-09-08Use g_hash_table_new_full() instead of g_hash_table_new() for subdissectorEvan Huus1-16/+8

2012-02-28Fix https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=3315 -Jeff Morriss1-0/+9
make Save-As/Displayed/All-Packets save not only the displayed packets but also any other packets needed (e.g., for reassembly) to fully dissect the displayed packets. This works only for the "All packets" case; choosing only the Selected packet, the Marked packets, or a range of packets would require actually storing which packets depend on which (too much memory) or going through the packet list many times (too slow). Also, this behavior is always the case: you can't save the displayed packets without their dependencies (I don't see why this would be desirable). So far this is done for SCTP and things using the reassembly routines (TCP has been tested). The Win32 dialog was modified but hasn't been tested yet. One confusing aspect of the UI is that the Displayed count in the Save-As dialog does not match the number of displayed packets. (I tried renaming the button "Displayed + Dependencies" but it looked too big.) The tooltip tries to explain this and the fact that this works only in the All-Packets case; suggestions for improvement are welcome. Implementation details: Dissectors (or the reassembly code) can list frames which were needed to build the current frame's tree. If the current frame passes the display filter then each listed frame is marked as "depended upon" (this takes up the last free frame_data flag). When performing a Save-As/Displayed/All-Packets then choose packets which passed the dfilter _or_ are depended upon. svn path=/trunk/; revision=41216

2010-12-20Rename the routines that handle dissector tables with unsigned integerGuy Harris1-30/+33
keys to have _uint in their names, to match the routines that handle dissector tables with string keys. (Using _port can confuse people into thinking they're intended solely for use with TCP/UDP/etc. ports when, in fact, they work better for things such as Ethernet types, where the binding of particular values to particular protocols are a lot stronger.) svn path=/trunk/; revision=35224
2010-10-30Rev 29427 added packet_add_new_data_source() with a comment indicating thatJeff Morriss1-15/+1
the data source does not need to be allocated if (!tree). Rev 30158 took the if (!tree) check out indicating that the check was invalid. So: (since packet_add_new_data_source() now only calls add_new_data_source()), remove packet_add_new_data_source(). svn path=/trunk/; revision=34717

This is an expensive operation because we: * Disable the TRY_TO_FAKE_THIS_ITEM optimization * Use GString to store the protocols We should only do this if the 'hf_frame_protocols' is referenced (unlikely) svn path=/trunk/; revision=29733
2009-08-15This patch introduces packet_add_new_data_source() which effectively ↵Kovarththanan Rajaratnam1-3/+12
deprecates add_new_data_source(). This is based on the following observation: 1) The tvb + name (aka. data_source) is only used when the protocol tree is visible The current implementation of add_new_data_source() doesn't take this into account and simply allocates a data_source regardless. This is what packet_add_new_data_source() tries to rectify. A couple of dissectors have already been switched over to the new packet_add_new_data_source(). Many are still missing.
