4.0.28-1

• libpacketdump: add decode support for new ETSI CC formats

Libtrace 4.0.27

• Added new API methods: trace_get_uri_format() and trace_get_uri_body().
• etsilive: added ability to have keepalive messages be returned by packet read functions by setting the environment variable LIBTRACE_ETSILI_SHOW_KEEPALIVE.
• ndagtcp: fix uninitialised address size when accepting connections
• ndagtcp: fix packet reassembly bug that would occasionally result in malformed packets.
• ndag / ndagtcp: set libtrace error state when a received packet is unable to be parsed due to invalid header content.
• Fixed parsing bug in trace_set_configuration() that affected configuration strings that ended in a ] character.
• ndagtcp: fixed bug where the beacon thread would not be started for ndagtcp inputs that were started after a previous ndagtcp input had been paused or destroyed.

Libtrace 4.0.26

Bug fixes

• pcapfile: preserve nanosecond timestamp resolution from original input file when writing pcap files.
• ndag: fix very minor memory leak.

Libtrace 4.0.25

Bug fixes

ndag: fix bug that prevented the most recently received packets from being readable if the multicast source does not send any further packets.

Libtrace 4.0.24

This release fixes a number of bugs in the ndagtcp: input and traceucast tool that were added in the previous release.

• ndagtcp: fix miscalculation of ERF header length that would prevent packets from being able to be decoded correctly.
• traceucast: do not exit if the client disconnects, instead try to reconnect and resume unicasting.
• traceucast: fix memory errors when attempting to send a captured packet that is larger than 10K bytes.
• ndagtcp: fix issue that would cause input to silently stop reading if it received a packet larger than 10K bytes.
• ndagtcp: fix lock-up that occurred when trying to halt a program that was reading from an ndagtcp input.
• ndagtcp: fix erroneous "Malformed beacon" message when an ndagtcp input reconnects to traceucast.
• traceucast: fix getaddrinfo memory leak.
• traceucast: fix endless reconnection loop bug.
• traceucast: fix race condition that would prevent Ctrl-C from halting traceucast properly.

Libtrace 4.0.23

New features:

• Added new tool: traceucast, a TCP unicast variant of tracemcast.
• Added new input format: ndagtcp:, for receiving packets sent by traceucast.

Bug fixes

• libpacketdump: fix premature free when decoding IPMM IRIs received via an etsilive input.
• tracemcast: fix bug where the sequence number was not being incremented for each sent datagram.
• object cache data structure: fix potential segfault after resizing the cache.
• pcapfile: fix issue where packets owned by "dead" pcapfile trace would have an invalid pcap version.

Libtrace 4.0.22

• Fix segmentation fault when closing an ndag input that had set a hasher function and was configured to use multiple processing threads.
• Disable setting a hasher function on ndag inputs, as this is not generally a good idea anyway (ndag inputs are already hashed by the ndag sender).
• Fix problem where trace_write_packet() would throw an error on ring outputs because a write could not be completed without blocking and there was no mechanism for trying the write again later.

Libtrace 4.0.21

New features

• Added new supported file format: etsifile -- to read and write binary files containing ASN.1 encoded ETSI LI intercept records.

Bug fixes

• Fixed issue where idle per packets threads would use 100% CPU constantly.
• Fixed numerous build issues on Mac OS X caused by changes in the BPF headers.
• Fixed bug where packets returned by trace_event() for certain live formats would not work with subsequent API calls.
• Fixed problems with compiling XDP support on more recent buildchains.

Libtrace 4.0.20

Bug fixes

• Fixed compilation issues for XDP module when using more recent versions of libbpf and libxdp
• Replace outdated macros in configure script

Improvements

• libpacketdump can now decode ETSI LI email CCs and IRIs

Libtrace 4.0.19

Bug fixes

• Fixed compilation issues when building against DPDK 21.11
• Incorporate various build system patches from Gentoo
• Fix ./configure syntax error on Mac OS
