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