There is no field, you have to use accessor function
sip_alert_info(sip) (which will return pointer to sip_alert_info_t
struct).

Summary: Memory leak in handling of incoming ACK request

Initial Comment:
Valgrind reports leaks in a simple UAS application written using Sofia-NUA 
library (1.12.7). One possible leak which has been noticed is in handling of 
incoming ACK request for 2xx response. 

Prelim analysis suggests that the memory home for the incoming ACK request is 
not un-ref-ed (since it is not stored as separate irq object in any saved list)

Adding the following code block (delimited by PATCH_START comment in code 
snippet below) at the end of nua_event() function in nua.c fixes the leak. This 
may not be the proper fix.



/*# Receive event from protocol machine and hand it over to application */
void nua_event(nua_t *root_magic, su_msg_r sumsg, event_t *e)
{
  nua_t *nua;
  nua_handle_t *nh = e->e_nh;
  enter;

  e->e_nh = NULL;

  if (nh) {
if (!nh->nh_ref_by_user && nh->nh_valid) {
  nh->nh_ref_by_user = 1;
  nua_handle_ref(nh);
}
  }

  if (!nh || !nh->nh_valid) {   /* Handle has been destroyed */
if (nua_log->log_level >= 7) {
  char const *name = nua_event_name(e->e_event) + 4;
  SU_DEBUG_7(("nua(%p): event %s dropped\n", (void *)nh, name));
}
if (nh && !NH_IS_DEFAULT(nh) && nua_handle_unref(nh)) {
#if HAVE_NUA_HANDLE_DEBUG
  SU_DEBUG_0(("nua(%p): freed by application\n", (void *)nh));
#else
  SU_DEBUG_9(("nua(%p): freed by application\n", (void *)nh));
#endif
}
if (e->e_msg)
  msg_destroy(e->e_msg), e->e_msg = NULL;
return;
  }

  nua = nh->nh_nua; assert(nua);

  if (NH_IS_DEFAULT(nh))
nh = NULL;

  if (e->e_event == nua_r_shutdown && e->e_status >= 200)
nua->nua_shutdown_final = 1;

  if (nua->nua_callback) {
nua_event_frame_t frame[1];

su_msg_remove_refs(sumsg);/* Remove references to tasks */
su_msg_save(frame->nf_saved, sumsg);
frame->nf_nua = nua;
frame->nf_next = nua->nua_current, nua->nua_current = frame;

nua->nua_callback(e->e_event, e->e_status, e->e_phrase,
  nua, nua->nua_magic,
  nh, nh ? nh->nh_magic : NULL,
  e->e_msg ? sip_object(e->e_msg) : NULL,
  e->e_tags);

su_msg_destroy(frame->nf_saved);

if (frame->nf_nua == NULL)
  return;
nua->nua_current = frame->nf_next;
  }

/* __PATCH_START__ */
  if (e && e->e_msg && e->e_event == nua_i_ack)
  {
 /*specific for ACK event*/
 su_home_unref(msg_home(e->e_msg));
  }
/* __PATCH_END__ */



  if (nh && nua_handle_unref(nh)) {
#if HAVE_NUA_HANDLE_DEBUG
SU_DEBUG_0(("nua(%p): freed by application\n", (void *)nh));
#else
SU_DEBUG_9(("nua(%p): freed by application\n", (void *)nh));
#endif
  }
}

Could you have a peek in 407 response, is the
sip->sip_proxy_authenticate non-NULL? Does nua call auc_challenge()?

Hi Pekka,
thanks for the response.

1) I have modified the proxy to send some realm and it didn't help.
2) reINVITE
I'm not sure how the reinvite works so I have just tried this piece of code:
nua_invite(nh, TAG_END());
Problem is that the invite is sent, but it's not challenged. (Don't have 
an idea why. Proxy is Alcatel OmniPCX enterprise.)
3) I have tried to debug deep into the bovels of sofia and I have found 
that in the function nua_stack_authenticate value of nh->nh_ds->ds_cr is 
NULL.
Also nh_authorize returns 0.

I don't know what might help you in tracking down the issue, but if you 
give me some more pointers I will try to find more.

Thanks
Martin

Hm. And when auc_challenge returns, is nh->nh_auth updated?

auc_challenge is called, but the first parameter (nh->nh_auth) is NULL.
sip->sip_proxy_authenticate has some data inside.

Re: [Sofia-sip-devel] SIPTAG_P_PREFERRED_IDENTITY()

2008-01-23 Thread Jerry Richards

Hi,

Okay, I added a call to sip_alert_info(sip) in the callback function when I
receive the nua_i_invite 100 event.  However, the ai_params and ai_url
fields of the sip_alert_info_t structured returned from sip_alert_info() is
not valid ASCII data (i.e. negative numbers).

Is there any other way to get at that data?  Or anything else I can try?

Best Regards,
Jerry

There is no field, you have to use accessor function
sip_alert_info(sip) (which will return pointer to sip_alert_info_t struct).

Re: [Sofia-sip-devel] SIPTAG_P_PREFERRED_IDENTITY()

2008-01-23 Thread Michael Jerris

You can access the whole header as:

sip_header_as_string(profile->home, (void *) alert_info);

ai_url should be a url_t, not ascii data... if you are printfing it as  
%d it might show as a negative number.

ai_params is a msg_param_t * , so a double pointer, its essentially a  
list of const char *, so to access the first param, you would do  
**ai_params.

[Sofia-sip-devel] ANNOUNCE: Sofia SIP release 1.12.8

2008-01-23 Thread Pekka Pessi

Hello all,

The latest and most shiniest Sofia SIP 1.12.8 is now out. The source
tar is available from sourceforge.net, the CVS on sourceforge.net has
been updated, and the up-to-date sources are also available from our
darcs repo at .

The release notes can be found below.

--Pekka

===
Release notes for Sofia SIP version 1.12.8 (2007-01-23)
===

Sofia SIP is an open-source SIP User-Agent library, compliant with
the IETF RFC3261 specification. It can be used as a building block
for SIP client software for uses such as VoIP, IM, and many other
real-time and person-to-person communication services. The primary
target platform for Sofia SIP is GNU/Linux. Sofia SIP is based on a
SIP stack developed at the Nokia Research Center. Sofia SIP is
licensed under the LGPL.


==
Release notes for Sofia-SIP 1.12.8

Changes since last release
--

Beside bugfixes, a server graylisting was added to nta and a few
improvements in event handling were made in nua interface.

A check-based test program was added, too.

API/ABI changes and versioning
--

New features in API are marked with Doxytag macro @NEW_1_12_8 or
@VERSION_1_12_8.

libsofia-sip-ua:
- Added nta_sip_is_internal(), nta_msg_is_internal() function in
  . Deprecating nta_is_internal_msg().
- Added su_msg_new(), su_msg_send_to() and su_msg_deinitializer() for more
  robust and light-weight message passing in 
- Added su_home_lock(), su_home_trylock(), and su_home_unlock() in
  
- Added type-neutral template macros for hash tables
HTABLE2_DECLARE2(), HTABLE2_PROTOS2(),
  and HTABLE2_BODIES2().
- Added sres_cache_set_srv_priority() in  and
  sres_set_cached_srv_priority()  for graylisting
  SRV records for inresponsive servers.
- nua_create()/nta_agent_create()/tport_bind() now joins to multicast group
  if "maddr" parameter is specified
- This release is ABI/API compatible with applications linked against
  any 1.12.x release. However, applications built against this release won't
  work against an older library. The ABI has been tested with the nua module
  unit test (test_nua) built against original 1.12.0 release.

libsofia-sip-ua-glib:
- No ABI/API changes, compatible with 1.12.0. Note, libsofia-sip-ua-glib
  interface is not considered stable and may change in a future 1.12.x
  release.

Contributors to this release


- Bernhard Suttner contributed patch to soa for using a=inactive attribute
  with call hold
- Stefan Leuenberger from Netmodule contributed the hack for changing
  priority of SRV records if a SIP server was inresponsive
- Daniele Rondina contributed patches fixing crash in STUN discovery cleanup
  and for transport handling with nta_outgoing_*create()
- Youness Alaoui sent a iPhone build fix
- Michael Jerris and Stefan Knoblich from Freeswitch project reported
  numerous bugs and contributed fixes

See the AUTHORS file in the distribution package.

Notes on new features
-

* SIP Server Graylisting

  The hack contributed by Stefan Leuenberger from Netmodule changes the
  priority of SRV records which are used when SIP URI is resolved.

  If your domain has multiple servers, you can define separate SRV records
  for them. If any of them becomes unresponsive, a SIP request sent to it
  times out or gets rejected because of network error and Sofia SIP
  automatically retries with another server. However, as Sofia SIP does not
  keep track of failed servers with the next request it may again try first
  the failed server. The graylisting reprioritizes the SRV records so that the
  priority of the failed server gets reduced and it won't be tried again
  until all other servers have failed, too. Note that the SIP URI resolver
  may get confused when using this kind of reprioritizing if a single SRV
  record corresponds to multiple servers or servers with multiple addresses.

  You can disable the reprioritizing hack by including tag
  NTATAG_GREYLIST(0) with nua_create(), nua_set_params(), nta_agent_create()
  or nta_agent_set_params().

Bugs fixed in this release

[Sofia-sip-devel] Registration/Subscription Refresh

2008-01-23 Thread Jerry Richards

Hello All,

What are the intervals that sofia-sip refreshes registrations
(nua_register())?  And Subscriptions (i.e. nua_subscribe())?

I presume it's a function of the Expires field?  The reason I'm asking is
that it does not appear consistent.

Best Regards,
Jerry

The refresh interval is based on expires parameter in Contact for
REGISTER and in Subscription-State header for SUBSCRIBE. (If there is
none, I think Expires is used instead). The actually used refresh
interval is random, see nua_dialog_usage_set_refresh() in
nua_dialog.c.
