|
||
18-Jun-2004: - 2 fixes for using a port number != 5060 (by Miguel Angel)
|
||
13-Jun-2004: - fix: get_ip_by_host() and buffer allocation for reentrant
|
||
gethostbyname_r() functions
|
||
- if compiled for fli4l 2.0.x, don't use reentrant
|
||
gethostbyname_r() - in some cases it fails reproduceably
|
||
when running under fli4l (however, the same binary
|
||
does behave properly under an old SUSE libc5 system)
|
||
12-Jun-2004: - use SIGUSR2 for dmalloc debugging (SIGUSR1 is occupied
|
||

- reworked calling parameters for passing SIP data
|
||
11-Jun-2004: - silenced some MSN Messenger provoked WARNings
|
||

||
09-May-2004: - Authentication headers: enquote Realm (linphone)
|
||
- complain about empty values in config file
|
||
- fli4l-uclibc: statically link against libpthread
|
||
(as it seems to be not included in fli4l distribution)
|
||
02-May-2004: - better recognition of redirected incoming requests
|
||
(like INVITES from sipgate.de - SIP URI points to
|
||
the real wanted target but To: header only points to
|
||
the initially wanted target before the redirection)
|
||
- compiling on BSD (fwapi.c, custom_fw_module.c)
|
||
11-Apr-2004: - on termination, stop all active RTP streams

||
requests pass through to a 3rd party registrar.
|

31-Jan-2004: - Allow 2 of my vias in header to let 2 UA's sitting
|
||
behind the same siproxd have conversation together
|
||

|
||
siproxd Registrar
|
||
UA2 --<--/ < \--<--/
|
||
- Redone code for evaluation if a received packet
|
||
is coming from the inbound or outbound network
|
||
- RTP streams are now identified by call_id AND
|
||
USERNAME of the contact header. This provides
|
||
support for RTP proxying between 2 UAs sitting on the
|
||
inbound network. -> Calls between local UAs going via
|
||
siproxd should now work.
|
||
UA1 -->--\
|
||
siproxd
|
||
UA2 --<--/
|
||
- Rewriting of SUBSCRIBE messages should now work.
|

|
||
better sense (changed meaning in fullduplex RTP proxy)

|
||
- better branch parameter calculation (via header),
|
||
now honors RFC3261 for stateless proxies (section 16.11)
|
||
- SIP request: remove a Route header pointing to myself.
|
||
This was an issue with Linphone 0.12.1.
|
||
(patch from Robert H<>gberg).
|
||
- removed IPCHAINS & IPTABLES (netfilter) proxy support
|
||
- RTPPROXY correction: match RTP ports crosswise -
|

use one single port (and socket) on each side (inbound/
|
||
outbound) to send and receive RTP traffic for every
|
||
active stream (patch from Christof Meerwald).
|
||
22-Jan-2004: - ./configure option: --enable-static to build
|
||
a completely statically linked executable

|
||
his work on this). Up to now, only the RTP *Relay*
|
||
has been tested (it works with KPhone, BudgeTone)
|
||
- fix: SIP phones that allocate a random port for
|
||
incomming SIP traffic should now work (like BudgeTone)
|
||
- fix: some SIP phones do change the RTP port number
|
||
during a session (like KPhone during HOLD/unHOLD)
|
||
- textual corrections
|
||
15-Dec-2003: - use only even port numbers for RTP traffic
|
||
05-Dec-2003: - some changes & enhancements inspired by Chris Ross:
|
||

(the resolver needs a shared lib that was tried
|
||
to load AFTER chrooting...)
|
||
22-Nov-2003: - utils.c: use gethostbyname_r() in favor of
|
||
gethostbyname - if available (siproxd uses threads!)
|
||
- some small items & cleanup
|
||
19-Nov-2003: - Integrated a patch from Chris Ross:
|
||
* have siproxd compile on Solaris and BSD/OS (more to come)

|
||
port could end up as -1 in the rewritten packet.
|
||
1-Nov-2003: - siproxd can use another outbound proxy (chaining)
|
||

||
which lead to syslog entries from IPCHAINS complaining
|
||
about 'already used connection' in the syslog.
|
||
- added INFO() for incomming SIP Calls
|
||
04-Oct-2003: - Siproxd now also works as outbound proxy 'only',
|
||
means that local UAs may register themselfes to a
|
||
3rd party registrar and use siproxd only as oubound
|
||
proxy for masquerading purpose.
|
||
- fixed some errors with callid handling (NULL pointers)
|
||
24-Sep-2003: - corrected the calling arguments of rtp_masq dummy
|
||
routines (non IPCHAINS capable kernels)
|

||
- rtpproxy: cleaned up some stuff with handling of FD's
|
||
|
||
0.3.4
|
||
=====
|
||
05-Aug-2003: - released 0.3.4
|
||
31-Jul-2003: - now supports OSIP2 only (due to rather big changes

|
||
descriptor" errors each time a RTP stream timed out
|
||
- fixed daemonizing (libc5) - now it properly detaches
|
||
30-May-2003: - always log ERROR, WARNING and INFO to syslog (also

- supports libosip2 (automatically detect osip1/osip2)
|
||
- redone authentication - now should work with libosip2
|
||
libosip0.8.8 has a bug (fails in parse_msg)
|
||
- 28-May-2003: - changes in rewriting SIP messages - not everything
|
||
is blindly rewritten now (e.g. SUBSCRIBE is NOT)
|
||
- fixed resource leak (sockets) in get_ip_by_ifname
|
||
- 26-Mar-2003: - Bugfix: some potential NULL pointers passed to atoi()
|
||
of optional fields in SIP message could lead to crash
|
||
- 23-Mar-2003: - send 403 FORBIDDEN response to requests addressed
|
||
to proxy itself (-> SUBSCRIBE bug)
|
||
|
||
0.2.8
|
||
=====
|
||
- 23-Mar-2003: - released 0.2.8
|
||
- made compile with uClibc (see doc/FLI4L_HOWTO.txt)
|
||
- 22-Mar-2003: - made compile on SUSE5.3 (libc5)
|
||
- added --enable-almost-static feature switch. This will
|
||
build siproxd statically linked against libosip & pthreads
|
||
(for Fli4l use)
|
||
- 16-Mar-2003: - ERROR on unknown keywords in config file
|
||
- introduced INFO logging
|
||
|
||
0.2.7
|
||
=====
|
||
- 15-Mar-2003: - released 0.2.7
|
||
- 9-Mar-2003: - replaced get_ip_by_ifname by simpler code
|
||
(still to be *BSD tested)

|
||
configuration. This is only done via interface names
|
||
- experimental: The host part of UA registration entries
|
||
can be masqueraded (mask_host, masked_host config items)
|
||
Siemens SIP phones seem to need this 'feature'.
|
||
|
||
0.2.6
|
||
=====
|
||
- 28-Jan-2003: - released 0.2.6
|
||
- New Feature: RTP proxy should be able to handle multiple
|
||
media stream in the same session (audio + video)
|
||
- 21-Jan-2003: - Bugfix: crash in compare_url (MSN Messenger issue)
|
||
- 19-Jan-2003: - use of libosip-0.9.3 not possible yet -
|
||
libosip fails in msg_setproxy_authenticate
|
||
-> Bug in libosip? to be investigated!
|
||
- give IP address in debug for 'received packet'
|
||
- 'WARNING:proxy.c:202 request from/to unregistered UA' now
|
||
includes sender and destination url
|
||
- 17-Jan-2003: - OpenBSD: do not link against gnugetopt (Luke Renn)
|
||
|
||
0.2.5a
|
||
======
|
||
- 6-Dec-2002: - released 0.2.5a (major bugfixes)
|
||
- Bugfix: interfaces on odd positions (the 1st , 3rd, 5th)
|
||
have been skipped during the search (ip by interface)
|
||
- Bugfix: MSN messenger 4.6 caused a segfault due to
|
||
non supplied username in contact header during
|
||
registration. (Credits to Dhiraj Bhuyan for the hint)
|
||
Included additional tests in that area.
|
||
- 4-Dec-2002: - fixed a major (but stupid) bug in check_vialoop. Siproxd
|
||
wrongly claimed to have detected a loop...
|
||
|
||
0.2.4
|
||
=====
|
||
- 23-Nov-2002: - released 0.2.4 (feature enhancements)
|
||
- BSD: resolved some compatibility issues (sscanf ->
|
||
resulted in coredump when reading config file)
|
||
should now build on *BSD (tested on FreeBSD 4.7)
|
||
- inbound/outbound interfaces now can be specified
|
||
by their interface name - this removes the need
|
||
for a 'quasi' static IP and restarting siproxd at
|
||
change of IP address.
|
||
- 13-Nov-2002: - working on portability - goal is building on *BSD
|
||
(feedback from Georg Schwarz)
|
||

|
||
- 8-Nov-2002: - string manipulations & data structures: better error
|
||
handling on some places.
|
||

|
||
of debug_level.

|
||
symbolic values and is more consistent
|
||
- added individual user passwords for authentication
|
||
|
||
0.2.1
|
||
=====
|
||
- 28-Sep-2002: - Released version 0.2.1
|
||
- 27-Sep-2002: - first implementation of proxy authentication (for REGISTER)
|
||

0.1.3
|
||
=====
|
||
- 11-Sep-2002: - Fixed a error in the autoconf/automake part of the project.
|
||
(scripts subdirectory was missing in the tar.gz archive.
|
||
This resulted in an error during ./configure - complaining
|
||
about non existent install-sh script)
|
||
- startup is more silent - set initial debug level to 0
|
||
- 10-Sep-2002: - Some (yea, I know...) -minor- docu updates
|
||
- 8-Sep-2002: - Masquerade Contact Headers of inbound clients
|
||
(Contact header will be used by the remote SIP
|
||
user agent to directly contact the local user agent -
|
||
and bypassing the proxy. This of course will *not* work
|
||
if the local user agent is located in a private IP range.)
|
||
- Performance optimizations in RTP proxy
|
||
- Bugfix: now masqueraded clients work with any
|
||
SIP port (other than 5060). Before, incoming
|
||
requests/responses where always sent to port 5060.

||

||
- 26-Aug-2002: - Optimized DNS caching
|
||
|
||
