31 | - Version 2.0.25 (unreleased) |
---|
32 | * updated rtclient_read_packet to be compatible with new rt protocol |
---|
33 | * rtclient input now correctly ignores packets with type = RT_MSG |
---|
34 | |
---|
35 | - Version 2.0.24 |
---|
36 | * minor bugs in format_erf |
---|
37 | * applied autoconf to tools/ dir - these are now built and installed |
---|
38 | automatically |
---|
39 | * added --disable-libpacketdump and --disable-tools configure options |
---|
40 | * improved checking for libpcap |
---|
41 | * improved checking for g++ (needed for libpacketdump) |
---|
42 | |
---|
43 | - Version 2.0.23 |
---|
44 | * configure fixes for dag |
---|
45 | * set attributes on functions to improve compiler caching |
---|
46 | * include tools/ dir in distributed tar.gz |
---|
47 | * added get_framing_length format function, to return the length |
---|
48 | of any framing headers added by the capture process (eg, pcap or |
---|
49 | ERF headers) |
---|
50 | * added libpacketdump, a library for dumping out packet information |
---|
51 | * updated tracedump to use libpacketdump, and copied it to the tools/ |
---|
52 | directory |
---|
53 | |
---|
54 | - Version 2.0.22 |
---|
55 | * Documentation updates |
---|
56 | * Added pcap_dump_flush() replacement function |
---|
57 | * Better doxygen detection |
---|
58 | * Support for legacy DAG POS, ATM and Ethernet formats |
---|
59 | |
---|
60 | - Version 2.0.21 |
---|
61 | * fixed error in output erf code, where we were missing 2 bytes |
---|
62 | * will skip vlan headers |
---|
63 | * added trace_decode_uri() function |
---|
64 | |
---|
65 | - Version 2.0.20 |
---|
66 | * byte-ordering fixups for WAG |
---|
67 | * writer functions for pcap and wag |
---|
68 | * fix of writer functions for erf |
---|
69 | * format conversion into pcap and erf formats |
---|
70 | * format conversion only applies if input not already in the right |
---|
71 | format |
---|
72 | * move internal fifo* symbols to tracefifo* to prevent collision |
---|
73 | with libfifo |
---|
74 | |
---|
75 | - Version 2.0.19 |
---|
76 | * Move code for different input formats (erf, pcap, wag) into |
---|
77 | separate modules, load and initialise on library load. |
---|
78 | * Add support for primitive trace writing |
---|
79 | See trace_output_create(), trace_output_destroy(), and |
---|
80 | trace_write_packet() |
---|
81 | * Added trace_perror() and libtrace errno functionality. |
---|
82 | |
---|
83 | - Version 2.0.18 |
---|
84 | * When opening a trace file, call open() with O_LARGEFILE set and |
---|
85 | pass the fd into gzdopen/fdopen. |
---|
86 | * Distributions should include man pages and other doxygen generated |
---|
87 | output |
---|
88 | * make install will install man pages into $PREFIX/man/man3 |
---|
89 | * fixed some compilation bugs in most of the examples |
---|
90 | |
---|
91 | - Version 2.0.17 |
---|
92 | * Fixed a bug in trace_get_erf_timestamp for the pcap path. |
---|
93 | Timestamps were not being fabricated correctly. This also |
---|
94 | effected trace_get_seconds, as that calls trace_get_erf_timestamp |
---|
95 | internally. |
---|
96 | * If bpf_setfilter() fails, output the filterstring it failed on |
---|
97 | * Fixed compilation bug under older distributions (woody), where |
---|
98 | the LTLIBOBJS auto* macro wasn't being expanded correctly |
---|
99 | |
---|
100 | - Version 2.0.16 |
---|
101 | * Ported to OpenBSD - mad props to meanphil |
---|
102 | * Fixed a bug in the event api where it would die instantly |
---|
103 | for offline traces. |
---|
104 | * Added trace_get_{source,destination}_port |
---|
105 | * Added some constification fixes |
---|
106 | |
---|
107 | - Version 2.0.15b |
---|
108 | * Fix a memory leak |
---|
109 | * Correct calls to trace_get_link to catch a NULL returned |
---|
110 | when an RX error is detected, handle this, and pas it up |
---|
111 | the chain where appropriate |
---|
112 | * Use a pcap callback handler when trace_read_packet() reads from |
---|
113 | a live pcap source. This gives us better diagnostics, such as |
---|
114 | being able to tell if an error occured. Also fixed a bug under |
---|
115 | FreeBSD where pcap would block until a buffer was full, then |
---|
116 | would let pcap_next iterate over all of them. |
---|
117 | |
---|
118 | - Version 2.0.14 |
---|
119 | * Added support for pcap decoding of PPP interfaces (DLT_LINUX_SLL) |
---|
120 | This DLT provides a direction bit, which we make use of in |
---|
121 | trace_get_direction(). Check the docs for the specifics |
---|
122 | * Fixed a bug where ERF traces weren't being checked for rxerrors. |
---|
123 | If the ERF record indicates an rxerror, then get_link() returns |
---|
124 | NULL. |
---|
125 | * Removed an extra , which was preventing compilation under gcc 3.4 |
---|
126 | in FreeBSD |
---|
127 | |
---|
128 | - Version 2.0.13 |
---|
129 | * Improved source docs / doxygen |
---|
130 | * Added functions to retrieve TCP, UDP and ICMP headers encapsulated |
---|
131 | within the IP sublayer |
---|
132 | * get_tcp_from_ip() |
---|
133 | * get_udp_from_ip() |
---|
134 | * get_icmp_from_ip() |
---|
135 | * Added trace_get_next_option to parse TCP/IP options within a |
---|
136 | libtrace_packet object |
---|
137 | |
---|
138 | |
---|
139 | - Version 2.0.12 |
---|
140 | * check for IP Fragmentation - if so, don't return TCP header on a |
---|
141 | fragmented packet |
---|
142 | |
---|
143 | - Version 2.0.11 |
---|
144 | |
---|
145 | * Added in a fallback function for strndup under freebsd. |
---|
146 | Thanks to mjl for this code. |
---|
147 | |
---|
148 | - Version 2.0.10 |
---|
149 | * Removed some badly licensed code. |
---|
150 | |
---|
151 | - Version 2.0.9 |
---|
152 | * Added improved conditional codepaths for |
---|
153 | * PCAP |
---|
154 | * ZLIB |
---|
155 | * BPF |
---|
156 | * DAG |
---|
157 | - These sections of code are only compiled in if there is |
---|
158 | appropriate support for them in the OS / asked by configure. |
---|
159 | In the event of no zlib support, we use a fread interface for |
---|
160 | uncompressed trace files instead. |
---|
161 | |
---|
162 | - Version 2.0.8 |
---|
163 | * Added better configure time checking for pcap-bpf.h (ie, actually fail early if it can't find it or an equivalent) |
---|
164 | * Added trace_set_direction , to set the direction bit in an ERF based trace. |
---|
165 | * Added trace_truncate_packet, to truncate the packet at a specified length |
---|
166 | |
---|
167 | |
---|
168 | - Version 2.0.7 |
---|
169 | * Assorted bugfixes. |
---|
170 | |
---|
171 | - Version 2.0.3 |
---|
172 | * Fixed packet->size bug for pcap |
---|
173 | |
---|
174 | - Version 2.0.2 |
---|
175 | * Port to AMD64. Should also work on IA64 |
---|
176 | * Will compile cleanly under gcc-2.95 (Debian Woody) |
---|
177 | * Compiles cleanly under FBSD 4.5 and 5.2. |
---|
178 | |
---|
179 | - Version 2.0.1 |
---|
180 | * Port to FreeBSD. Thanks to Phil Murray for testing this |
---|
181 | |
---|
182 | - Version 2.0.0 |
---|
183 | * Major API change for cleanup purposes. |
---|
184 | * libtrace_packet_t object used to hold reference to the |
---|
185 | trace object, the buffer, and assorted variables |
---|
186 | * First autoconf release |
---|
187 | |
---|
188 | - Version 1.1.0 |
---|
189 | * Tagged as REL_1_1_0 |
---|
190 | * First final release tag |
