10.0 19.6.2014
==============
after several months of releasing 9.4 and 10.0RC/BETA versions there is new stable version 10.0 with many enhancements and bug fixes. The most interesting part is transparent pcap file compression and saving packet optimizations which allows to store thousands of simultaneous calls which was not possible before. The sniffer is now able to write pcap files for very high number of calls per second (>6000 / sec). Read the full changelog below:
Optimizations
-------------
- reimplement saving pcap files and add native gzip pcap and graph files which is enabled by default. Zipping is done in threads which dynamically grows. Use open/write sys calls instead of libc fwrite/fopen/fclose to allow store files at >6000 calls/second rate (impossible with libc fwrite/fclose functions). Any writes to file are asynchronous by default using different queue which will not block processing packets. New parameters in config/voipmonitor.conf - pcap_dump_bufflength, pcap_dump_zip, pcap_dump_writethreads, pcap_dump_writethreads_max, pcap_dump_asyncwrite, pcap_dump_asyncbuffer. Those optimizations does not require cachedir for very high I/O loads now.
- properly dequeue remote sensors by the timestamp to prevent race conditions or if sniffing on interface = eth1,eth2
- Optimize SIP parser which is now much faster
- do not try to parse callid on UDP packet if it cannot be SIP (can save some CPU)
- save few kB for each jitterbuffer channel (3 per RTP stream) - removed unused structures
- release calls from memory sooner and do not wait on rtptimeout for some cases
- end calls sooner than the rtptimeout if there is no further communication after 401 SIP response
- be more tolerant in jitterbuffer simulater to burst RTP packets - add 200ms more so the MOS is not negatively affected
- if mysql procedure fails run repair table mysql.proc which is the most common source of the issue
- implement new mysql fine tunning options - mysqlstore_concat_limit and mysqlstore_concat* - see voipmonitor.conf for more details
- modify packetbuffer log drop statistics (heapoverrun and drop packets on interace)
- repair table mysql.proc at every sniffer start (it is broken after hard restart very often...)
- shorten register sip message timeout from 30 to 5 seconds (helps to manage RAM when there is REGISTER flood) and add option sip-register-timeout so it can be set to custom seconds
- implement autocleaning to prevent 100% disk space usage. in case the space is below 1% and below 5GB (which is default threshold) reindexfiles procedure will be executed and cleaning will be restarted. In case this will not help the new maxpoolsize will be set to size of current spool directory and will keep free space MIN(1% freespace, 5GB). Default is autoclean enabled, 1% free space or 5GB free space. New configuration options: autocleanspool = yes, autocleanspoolminpercent = 1, autocleanmingb = 5
- if filesindex directory is missing at all or there are no data past 12 hours reindexfiles will be initiated on sniffer start
- use old partition schema even if mysql is upgraded from 5.1 to 5.6 - it autodetects old partitions.
Bugfixes
--------
- SIP 200 packet was never saved if it was not BYE or INVITE - all 200 to CANCEL were missing. (probably all versions)
- if RTP src/dst port was the same as sipports the RTP was ignored (fixes all versions)
- do not end call prematurily on 481 transaction does not exist
- fix beeping in silence sequences for G711 ALAW/ULAW (all versions)
- fix g729 garbled audio for annex B / cng
- fix ignoring RTP if the first RTP is TELEVENT (flash/dtmf etc) leading to silence in audio recording
- fix if device wants to unregister (send REGISTER expires=0) and server replies 200OK expires>0 the sniffer did not deregister it from active calls
- fix reassembling TCP which would lead to crash
- fix bug causing deadlock on 32bit
- fix race condition leading to crash in get sniffer status via manager
- fix crash in case the call is one-way SIP and RTP frames are held in heap due to I/O
- do not end sniffer when sending mirroring traffic to receiver and the connection resets - properly reconnect once the receiver is up again.
- fix pcap files when sending traffic from different interfaces (TUN / ETH) to one receiver
- fix indication in CDR when packet loss in kernel / heap is detected so in the GUI CDR shows the loss might be not real
- ensure that the left channel of the was is always caller
- take size of files from OS sys calls and do not rely on pcap caplen which fixes bug in cleaning which thinkgs there is much more space consumed
- fix audio if caller/called changes codec from one sample rate to another
- fix low MOS score in case call changes packetization from 10 to 20 and back to 10 which is pretty rare but it can happen
- fix SIP TCP reassemble ignoring some TCP messages in SIP (all versions)
- fix SIP TCP reassemble if the first SIP packet does not contain Call-ID it was not tracked at all.
- fix SIP TCP reassemble duplicate TCP packet - last fragment was stored twice
- fix racecondition when storing multiple calls from file - some of calls might not be saved due to preliminary end of the program not waiting to finish all queues
- fix crash if SIP type MESSAGE has larger content-lenght than the whole message.
- fix skinny skip flag
- resolve mysql host only in main thread which fixes issues on some systems which crashes when resolv is in multiple threads. The static binary is now compatible with all centos versions again.
- fix parsing DSCP bit
- fix race condition leading to crash when saving to wav is enabled
- fix regression for all versions >9.1 when (and only for) G729 RTP streams were not scored by MOS at all and although there were loss or delays the MOS was always 4.5.
- fix typo in voipmonitor.conf - onowaytimeout -> onewaytimeout
- fix small memory leak in case there is T38 in SDP (all versions)
- fix redundant reconnect to db - flush previous query before try mysql_ping (problem since 9.1)
- fix skinny racecondition crash and add support for more version headers for some messages
- fix skinny called/calling swapped
New features
------------
- add support for capture rules by domain
- parse multiple SIP messages carried in one TCP packet
- add call per second and sip packets per second to the syslog info line
- if the call timeouts due to absolute timeout mark this in cdr.bye - 103 so the GUI can alert / see it
- support reading compressed pcap files (-r)
- add G722.1 and AMR codec support
- add option only_cdr_next for save cdr only to cdr_next table
- enable merging calls based on matching call-id. The idea is that the second leg with different call-id has in the first INVITE special header which has the call-id of the parent SIP call. The configuration option specifies name of the header.
- add syslog messages when upgrading sniffer
- add connect_duration to listcalls manager command
- add new configuraiton option absolute_timeout (default set to 4 * 3600s) which ends call longer than 4 hours by default.
- add new configuration option destroy_call_at_bye which ends call after 20 minutes (default 20*60) no matter how many RTP/SIP packets arrives after the BYE.
- parse custom headers also for SIP 2XX methods
- replace wget with libcurl when doing autoupgrades from the manager
- implement saving audio in ogg / stereo / various sample rate (new config saveaudio_stereo default is stereo now). Add new option ogg_quality so user can control quality of the ogg file
- allow RTP stream to be assigned to two independent calls with different call-id.
- store RTP mark bit into .graph file so the GUI will show where mark bits are set
- implement new cdr.a_last_rtp_from_end and cdr.b_last_rtp_from_end which stores number of seconds from last RTP packet to the end of call. This will be used to find calls where any of side ends RTP stream sooner. Such situation is not yet detectable without knowing those parameters.
- add support for other GRE encapsulation types (for IP protocol)
- when mirroring packets send id_sensor and DLT number on connect so configuration option mirror_bind_dlt is not needed anymore and allows to set id_sensor for each sender. It is not backward compatible with older versions thus the receiver must be >= 9.4 beta1
- add time shift information to syslog if detect bad packet order
- sip_send_ip = 127.0.0.1 (or 127.0.0.1:12345) sip_send_port = 12345 will send text SIP messages to TCP socket
- implement skip flag also for cisco skinny protocol
- sccp skinny: record RTP stream for some cases where signalization does not contain conference number = call reference which fixes ampty RTP
- use only first detect value for custom headers or last if set configuration value custom_headers_last_value
9.3 10.2.2014
=============
- fix crashing when decoding audio in certain cases and also when doing realtime listening
- do not connect to database if nocdr is set (-c)
- fix crash if non ascii is put into telnum filter
- fix freebsd compile
- implement storing rtp port to cdr_rtp database (cdr_rtpport option must be set to yes and it will upgrade database)
9.2 31.1.2014
=============
- do not put CNG frames into audio decoders which causes garbled g729 stream and causes low MOS score even thought there is no packet loss at all
- use separate MySQL connections for live packet sniffer and for storing REGISTER messages which adds parallelization and speedups INSERTS
- fix ipaccount for GRE protocol
- add --no-cache parameter to wget in download upgrade
- fix issue with double semicolon in sql query
- add support for DLT_IEEE802_11_RADIO reading pcap files and sniffing on raw wifi
9.1 29.1.2014
=============
- Fix MySQL deadlock in case the MySQL connection timeouts. This bug started since 8.4 - 9.0 verisons.
- Fix storing to MySQL if file is read from file (bug introduced in 8.4 and 9.0 versions) and do not fork when reading from file
- Optimize failed registrations which caused mysql overload in case of register flood
- fix configuration issue in case the datbase is partitioned and cdr_partition was not set
- fix MySQL indefinit reconnect in case the sniffer is stopping or starting which causes hang in linux bootup / shutdown process.
- fix undefined codec in case of CNG (comfort noise) frames.
- add new option saveaudio_reversestereo which reverts left and right channels
- add new manager command pcapstat which prints ringbuffer packet drop counter
- fix issue in interface option when list of interfaces contains spaces like: interface = eth0, eth1
- support mysql 5.0
9.0 17.1.2014
=============
Version 9.0 is formerly 8.4RC27 and this changelog sumarizes all changes since 8.3 (all features from 8.4)
Optimizations
-------------
- do not create RTP pcap file for every sip call but only if there is actually RTP which saves a lot of I/O
- take min MOS score from fixed2 jitterbuffer simulator by default which eliminates low mos score due to f1 and adapt sensitivness
