libtrace 3.0.20 (2014-07-07)

Thanks to Nevil Brownlee and Alistair King for their invaluable bug reports.

New Features

  • Added new API function: trace_get_fragment_offset, which returns the fragment offset for a packet in bytes.
  • Added support to libwandio for reading and writing files compressed using LZMA (a.k.a. the 'xz' format). Thanks to Perry Lorier for contributing most of the code for this.
  • Added new tool to libwandio: wandiocat. This tool is essentially 'cat' using libwandio, so can natively decompress and compress files using any supported compression method.

Bug Fixes

  • Fixed broken snaplen option for ring: input.
  • Fixed trace_get_source_port and trace_get_destination_port returning bogus port numbers when given a fragmented packet.
  • Fixed timestamp byte ordering on big endian architectures.
  • Removed assert failure if a bad compression level or method is provided when configuring an output trace.
  • Fixed broken compiler feature checking in configure script.
  • Fixed potential segfaults in OSPF libpacketdump parser if the packet is truncated midway through the OSPF header. This unfortunately required the 'len' field in the libtrace_ospf_t structure to be renamed to 'ospf_len' -- if you are using libtrace to process OSPF packets, please make sure you update your code accordingly.

libtrace 3.0.19 (2014-02-21)

New Features

  • Added support for reading the pcap nanosecond file format (thanks to Martin Bligh for providing the original patch) (r1852).

Bug Fixes

  • Fix linking issue on FreeBSD 10, due to creating the distribution tarball with an old version of libtool.
  • Fixed incorrect decoding of RadioTap? and 802.11 headers by libpacketdump on big-endian architectures (r1850, r1851).
  • Fixed bug in set_capture_length for ring: format, which was modifying the wire length rather than the capture length (r1849).
  • Fixed bugs relating to inconsistent BYTE_ORDER macros across different OS's (r1841).
  • Fix bad GCC version check in configure script (r1856).
  • Fixed a number of potential (albeit unlikely) buffer overrun bugs in tracereport and tracesplit (r1863, r1865).
  • Fixed bad smoothing parameter in the rate-dir example (r1862).

Improvements

  • Explicitly defined the -1 values used for linktype and direction when libtrace cannot determine the value, e.g. TRACE_DIR_UNKNOWN for unknown direction (r1859)

libtrace 3.0.18 (2013-06-28)

Thanks to Perry Lorier for providing patches to fix the bugs found by the Mayhem team.

New Features

  • Added new format URI for reading trace files: rawerf. This is a special format that will always treat the provided file as an uncompressed ERF trace, without attempting any auto-detection of compression. If you are working exclusively with uncompressed ERF traces, it is recommended that you explicitly use this format to avoid the possibility of being hit by the bug reported in #351 (r1830).

Bug Fixes

  • Added an extra byte to the gzip auto-detection check, which should decrease the likelihood of a false positive when an uncompressed packet header just happens to match the gzip signature (r1828).
  • Fixed crashes in traceanon if certain arguments are specified incorrectly -- as reported by the Mayhem team from Carnegie Mellon University (r1832,r1833).
  • Fixed crashes in tracertstats if bad input URIs are provided -- as reported by the Mayhem team from Carnegie Mellon University (r1834,r1835).

Improvements

  • Added ability to globally disable compression auto-detection via the LIBTRACEIO environment variable (r1831).

libtrace 3.0.17 (2013-04-24)

New Features

  • Added functions trace_get_source_address_string and trace_get_destination_address_string that will extract the IP address from a packet and convert it into a string. (r1797)
  • Added functions trace_checksum_layer3 and trace_checksum_transport which will calculate the checksum for a given packet. They will also return a pointer to the checksum field in the header so it can be updated, compared, etc. (r1799)
  • Added function trace_get_icmp6 and trace_get_payload_from_icmp6, which should make working with ICMPv6 easier. (r1794)
  • Added support for OpenBSD Loopback captures - thanks to Kaio Rafael for submitting a patch to do this. (r1820)

Bug Fixes

  • Fixed bug where trace_event was broken for int: inputs. (r1793)
  • Fixed error in tracesplit where the input trace structure would not be completely destroyed if a stopping condition was reached. (r1796)
  • Fixed error where some of the threading data structures in libwandio were not freed properly. (r1795)
  • trace_get_payload_length now correctly handles ICMPv6 packets -- thanks to John Dickinson for reporting this bug and submitting a patch. (r1792)
  • Fixed bug where tracereplay was not calculating new TCP or UDP checksums for modified packets correctly. (r1800)
  • Fixed bug where legacy NZIX timestamps would be incorrect if the TZ environment variable is not set on the system (r1825)
  • Fixed bug where traceanon was not correctly anonymising IP headers embedded in ICMP messages (r1826)
  • Fixed oversight where ICMP checksums were not being anonymised in traceanon (r1826)

Improvements

  • Added examples to examples/tutorial that demonstrate trace_get_transport and trace_get_payload_from_ip. (r1798)
  • Better error reporting if libtrace fails to open an output file. (r1789)
  • Better error reporting if int: or ring: outputs fail to transmit a packet. (r1790)
  • Thanks to the new checksumming code, tracereplay should now update checksums for IPv6 packets. (r1800)
  • Libprotoident decoder with ICMP now prints the value of the ICMP checksum. (r1801)
  • Stopped libpacketdump from installing so many useless files and symlinks - thanks to Robert Edmonds for patching this. (r1818)

libtrace 3.0.16 (2013-01-03)

New Features

  • Added a new trace format (ring:) - ring: is a replacement for int: that uses PACKET_MMAP ring buffers to greatly improve performance when capturing from a live interface. (r1771, r1774)
  • Packets captured using int:, ring: and bpf: and exported over RT can now be decoded by any system, regardless of what OS it is running. Previously, only Linux systems would be able to decode int: or ring: packets sent over RT, for example. (r1780, r1782)

Bug Fixes

  • Fixed conversion errors when converting packets captured using pcapint:any to other formats -- Thanks to Simon Wadsworth for reporting this bug (r1768)

  • Fixed build error where iow-lzo.c would require (and not be able to find) libtrace.h (r1760)
  • Fixed build error where libpacketdump could not find wandio.h (r1761)
  • Fixed bug where TRACE_RT_LAST would overflow the 32-bit integer being used to store the RT packet type (r1763, #322)
  • Fixed bug where Linux Native input would give errors when being used to monitor a loopback interface (Thanks to Asad Arfeen for reporting this bug) (r1764)

Improvements

  • libtrace_sll_header_t data structure is now exported via libtrace.h, so it can be used in user code (r1759)
  • Better detection and reporting of cases where the user is trying to read a compressed format that their libtrace build doesn't support (r1762)

libtrace 3.0.14 (2012-03-06)

  • wandio functions are now exported through a separate shared library and can be used to do general file I/O (r1756, r1757)

libtrace 3.0.13 (2012-01-09)

  • Libpacketdump decoders for OSPFv2 packets (r1737)
  • New API function: trace_interrupt. Calling this function will cause a live capture that is blocking due to waiting on packets to immediately stop. This is useful when running your own signal handler (r1729).

Bug Fixes

  • Fixed bug where occasionally a trace file written using zlib would not be flushed correctly, resulting in a truncated trace (r1742)
  • Fixed annoying warnings that were caused by multiple definitions of ERF types when building with DAG support (r1725)

  • Updated pcap interfaces to use pcap_create and pcap_activate APIs in libpcap 1.0 (r1728)
  • Optimisations to trace_apply_filter (r1729)
  • Optimisations to tracestats (r1730)
  • Wire length is now cached for each packet (r1731)
  • Trace files created by programs running via sudo now belong to the user who was running sudo rather than root (r1732)

  • Fixed bug where trace_get_layer2 would return a meta-data header instead NULL when no layer 2 payload was present (r1714, #263)

Improvements

  • Added more caching to further improve performance in some cases (r1716)
  • Reworked trace_get_layer2 to be faster (r1716)
  • Added libpacketdump decoders for some IPv6 extension headers (hop by hop, routing and destination options) (r1713)

libtrace 3.0.11 (2011-07-06)

New Features

  • ECN bits in the TCP header are now directly accessible in the same fashion as other TCP flags. NOTE: this will break existing code that accessed the reserved bits that we have replaced with ECN flags, especially anything that attempted to access ECN prior to this release! (r1707)

Bug Fixes

  • Fixed bug where libtrace would fail at guessing the trace format for small trace files (r1708)
  • Fixed bug where using a BPF filter on a live DAG interface via the event API would result in bad packet lengths (r1706)
  • Fixed bug where BPF filters would cause an RT input source to fail (r1702)
  • Fixed bug where trace_event would not update the time to sleep properly if called before the timer has expired (r1700)
  • Fixed bug where constructed packets did not have their cached values initialised correctly (r1698)

Improvements

  • Tracepktdump now reports any errors that occur while reading packets (r1703)
  • Tidied up linking process so that components only link against libraries that they actually use - should make Debian packaging easier (r1701)
