Outbound flow failure handling merged to master
by Hugh Waite 23 Nov '16

23 Nov '16

Hello, As you will see I have merged my branch back into master. These changes add a new event route [tm:branch-failure] to the tm module which is run when any failure response is received on a transaction. The event_route uses a new route type BRANCH_ROUTE which limits the functions that can be run in the route. The functions t_check_status(), t_next_contact_flow(), t_relay() and unregister() can be used in this route. A new pv $T_reply_ruid is accessible in this route which can be used to unregister a single contact entry. The following example route can be used on a registrar to handle failed or invalid flows: event_route[tm:branch-failure] { xlog("L_INFO", "event_route[tm:branch-failure]\n"); if (t_check_status("430|403")) { if (!unregister("location", "$tu", "$T_reply_ruid")) { xlog("L_WARN", "failed to unregister $tu with ruid $T_reply_ruid\n"); } if (!t_next_contact_flow()) { xlog("L_INFO", "No more flows\n"); } else { xlog("L_INFO", "Next flow\n"); t_relay(); } } } Any bugs, memory leaks etc. let me know!

Using t_suspend()/t_continue() multiple times on the same transaction
by Peter Dunkley 02 Jul '14

02 Jul '14

Hi, I am trying to use t_suspend()/t_continue() multiple times on the same transaction. Calling t_suspend() more than once works, but the second time I call t_continue() the transaction is killed and a 500 response is sent. It is the "if (branch == t->nr_of_outgoings)" check from the code fragment below (from t_suspend.c:t_continue()) that results in the transaction being killed - you can see the debug/error line I added to determine this in the fragment. Is using t_suspend()/t_continue() multiple times something that should work? Thanks, Peter if (t->uas.status < 200) { /* No final reply has been sent yet. * Check whether or not there is any pending branch. */ for ( branch = 0; branch < t->nr_of_outgoings; branch++ ) { if ((t->uac[branch].request.buffer != NULL) && (t->uac[branch].last_received < 200) ) break; } if (branch == t->nr_of_outgoings) { /* There is not any open branch so there is * no chance that a final response will be received. */ ret = 0; LM_ERR("branch == t->nr_of_outgoings\n"); goto kill_trans; } } -- Peter Dunkley Technical Director Crocodile RCS Ltd

[PATCH] modules/sca: use Call-Info for canonical AoR
by Timo Teräs 22 Apr '14

22 Apr '14

RFC3261 8.1.1.2 states that To header "may or may not be the ultimate recipient of the request", and 8.1.1.3 states that From header is "possibly the user's address-of-record". So either of them cannot be fully trusted. This was already noted and fixed partially in commit 1ef4587612806a94 ("modules/sca: reconcile Contact and From URIs in ACK callback"). But similar issues happen when using ENUM and/or calling using local alias (numbers only, or local forward) and the destination is in another SIP domain. To-header contains the initial domain, and not the AoR domain. When handling response to such INVITE a sane way to determine correct AoR is to inspect the Call-Info header's Application Server URI. Thus this changes AoR canonicalization to happens as follow: 1. User portion is taken from Contact header if present, otherwise from the applicable From / To header. 2. Domain/port part is taken from Call-Info header if present, and otherwise from the applicable From / To header. --- This has not fully tested, but this seems to be the root case why SCA does not on certain inter-domain calls that I get. I'd like to get review comments, and possible other fix ideas. I'll let you know how the testing goes, and if looks OK to you can push this to master and relevant stable branches. modules/sca/sca_util.c | 51 +++++++++++++++++++++++++++----------------------- 1 file changed, 28 insertions(+), 23 deletions(-) diff --git a/modules/sca/sca_util.c b/modules/sca/sca_util.c index 143ac47..e209cc0 100644 --- a/modules/sca/sca_util.c +++ b/modules/sca/sca_util.c @@ -26,6 +26,7 @@ #include <assert.h> #include "sca_util.h" +#include "sca_call_info.h" #include "../../parser/sdp/sdp.h" @@ -343,9 +344,13 @@ sca_aor_create_from_info( str *aor, uri_type type, str *user, str *domain, sca_create_canonical_aor_for_ua( sip_msg_t *msg, str *c_aor, int ua_opts ) { struct to_body *tf = NULL; - sip_uri_t c_uri; - str tf_aor = STR_NULL; + str user_portion; + str domain_portion; + str port_portion = STR_NULL; str contact_uri = STR_NULL; + sip_uri_t c_uri; + sca_call_info call_info; + hdr_field_t *call_info_hdr; int rc = -1; assert( msg != NULL ); @@ -373,12 +378,6 @@ sca_create_canonical_aor_for_ua( sip_msg_t *msg, str *c_aor, int ua_opts ) } } - if ( sca_uri_extract_aor( &tf->uri, &tf_aor ) < 0 ) { - LM_ERR( "sca_create_canonical_aor: failed to extract AoR from " - "URI <%.*s>", STR_FMT( &tf->uri )); - goto done; - } - memset( &c_uri, 0, sizeof( sip_uri_t )); if (( rc = sca_get_msg_contact_uri( msg, &contact_uri )) < 0 ) { LM_ERR( "sca_create_canonical_aor: failed to get contact URI from " @@ -394,22 +393,28 @@ sca_create_canonical_aor_for_ua( sip_msg_t *msg, str *c_aor, int ua_opts ) } } - if ( SCA_STR_EMPTY( &c_uri.user ) || - SCA_STR_EQ( &c_uri.user, &tf->parsed_uri.user )) { - /* empty contact header or Contact user matches To/From AoR */ - c_aor->s = (char *)pkg_malloc( tf_aor.len ); - c_aor->len = tf_aor.len; - memcpy( c_aor->s, tf_aor.s, tf_aor.len ); + /* Prefer Contact header user, fallback to To/From */ + if ( SCA_STR_EMPTY( &c_uri.user ) ) + user_portion = tf->parsed_uri.user; + else + user_portion = c_uri.user; + + memset( &call_info, 0, sizeof( sca_call_info )); + call_info_hdr = sca_call_info_header_find( msg->headers ); + if ( !SCA_HEADER_EMPTY( call_info_hdr ) && + sca_call_info_body_parse( &call_info_hdr->body, &call_info ) >= 0 ) { + /* Call-Info present, use the server name as AoR domain */ + domain_portion = call_info.sca_uri; } else { - /* Contact user and To/From user mismatch */ - if ( sca_aor_create_from_info( c_aor, c_uri.type, - &c_uri.user, &tf->parsed_uri.host, - &tf->parsed_uri.port ) < 0 ) { - LM_ERR( "sca_create_canonical_aor: failed to create AoR from " - "Contact <%.*s> and URI <%.*s>", - STR_FMT( &contact_uri ), STR_FMT( &tf_aor )); - goto done; - } + /* Use To/From domain */ + domain_portion = tf->parsed_uri.host; + port_portion = tf->parsed_uri.port; + } + + if ( sca_aor_create_from_info( c_aor, c_uri.type, &user_portion, &domain_portion, &port_portion ) < 0 ) { + LM_ERR( "sca_create_canonical_aor: failed to create canonical AoR " + "user: <%.*s>, domain: <%.*s>", STR_FMT( &user_portion ), STR_FMT( &domain_portion )); + goto done; } rc = 1; -- 1.8.4

Removing carrierroute dependency on libconfuse
by Marius Zbihlei 21 Feb '14

21 Feb '14

Hi all, This has been in the back of my head from some time now. Libconfuse is a small project not distributed with major distros and unmaintained for 3.5 years now. As it is only used for reading of a simple cfg file, I want to write a simple parser that does the job(I do not want external deps ... see below why) Benefits: we can now pack carrierroute with the common used modules (as it will not have any external dependencies) and also will remove a lot of problems seen on the list regarding linkage of libconfuse. Any thoughts? Marius

default config: do loose_route() for in-dialog NOTIFY as per new RFC 6665
by Iñaki Baz Castillo 19 Feb '14

19 Feb '14

Hi, the new RFC 6665 mandates that the subscription dialog is made *after* the first NOTIFY from the UAS (rather than after the 200 to the initial SUBSCRIBE). This means that the UAC MUST take the route set from the *first* received NOTIFY (instead of taking it from the 200 to the initial SUBSCRIBE). Therefore a proxy compliant with RFC 6665 MUST always add RR to in-dialog NOTIFY requests and thus, I propose that the default SR script file implements it. Regards. -- Iñaki Baz Castillo <ibc(a)aliax.net>
