git:master: modules_k/rls: rls_presentity can now be in a different DB from rls_watchers

by Peter Dunkley

Module: sip-router Branch: master Commit: ca6d901216360694d7834cde05c875c5c141af66 URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=ca6d901… Author: Peter Dunkley <peter.dunkley(a)crocodile-rcs.com> Committer: Peter Dunkley <peter.dunkley(a)crocodile-rcs.com> Date: Fri Feb 10 16:18:05 2012 +0000 modules_k/rls: rls_presentity can now be in a different DB from rls_watchers - During performance testing it was observed that the rls_presentity table is hit very hard. Separating it off into a different table helps. - It may also be a good candidate for use with db_cassandra, and putting it in its own DB is a first step. - There are two new modparams, one for the dburl and one to give rls_presentity it's own clean period. Leaving these unset maintains the current behaviour. Using a different dburl and leaving the new clean period parameter unset puts rls_presentity in a different DB, but still uses the existing clean period for it (and rls_watchers). - Setting the new clean period parameter to 0 means that the timer to clean the rls_presentity table is not started at all. - Also cleaned up the xcap table query a little. The arrays allocated for it were larger than they needed to be. --- modules_k/rls/README | 286 ++++++++++++++++++++++----------------- modules_k/rls/doc/rls_admin.xml | 53 +++++++- modules_k/rls/notify.c | 18 ++-- modules_k/rls/resource_notify.c | 24 ++-- modules_k/rls/rls.c | 88 +++++++++++- modules_k/rls/rls.h | 2 + 6 files changed, 319 insertions(+), 152 deletions(-) Diff: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commitdiff;h=ca6…

git:master: modules_k/rls: made rls_handle_notify() send SIP error responses when things go wrong

by Peter Dunkley

Module: sip-router Branch: master Commit: 5c61d09717c7254d42458f549e02fb59d2d52162 URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=5c61d09… Author: Peter Dunkley <peter.dunkley(a)crocodile-rcs.com> Committer: Peter Dunkley <peter.dunkley(a)crocodile-rcs.com> Date: Fri Feb 10 16:24:09 2012 +0000 modules_k/rls: made rls_handle_notify() send SIP error responses when things go wrong - Currently it just silently drops the request - leaving the far end with stuck dialogs. - After this change 400/481/489/500 responses are returned as appropriate. - Also downgraded the "no presence dialog record for non-TERM.." ERR to INFO. This was helpful when looking for holes and race-hazards, but it can also occur a lot when the system is overloaded - obscuring real problems. For example... RLS Presence --- -------- SUBSCRIBE --> <-- 200 OK <-- NOTIFY 200 OK --> un-SUBSCRIBE --> <-- 503 (overload) - un-SUBSCRIBE not processed ...later... <-- NOTIFY 481 --> ("no presence dialog record for...") - With the latest updates RLS, PUA, and Presence dialogs are correctly removed when error responses are received (and the error responses are sent at the correct times). Some of these diagnostics are no longer errors, or even warnings. --- modules_k/rls/resource_notify.c | 41 ++++++++++++++++++++++++++++++++++---- 1 files changed, 36 insertions(+), 5 deletions(-) diff --git a/modules_k/rls/resource_notify.c b/modules_k/rls/resource_notify.c index 378035c..382d8d9 100644 --- a/modules_k/rls/resource_notify.c +++ b/modules_k/rls/resource_notify.c @@ -47,6 +47,10 @@ * winner: sol3 * */ static str su_200_rpl = str_init("OK"); +static str pu_400_rpl = str_init("Bad Request"); +static str pu_481_rpl = str_init("Call/Transaction Does Not Exist"); +static str pu_489_rpl = str_init("Bad Event"); +static str pu_500_rpl = str_init("Server Internal Error"); int parse_rlsubs_did(char* str_did, str* callid, str* from_tag, str* to_tag) { @@ -506,24 +510,31 @@ int rls_handle_notify(struct sip_msg* msg, char* c1, char* c2) struct hdr_field* hdr= NULL; int n, expires= -1; str content_type= {0, 0}; - + int reply_code = 500; + str reply_str = pu_500_rpl; LM_DBG("start\n"); /* extract the dialog information and check if an existing dialog*/ if( parse_headers(msg,HDR_EOH_F, 0)==-1 ) { LM_ERR("parsing headers\n"); - return -1; + reply_code = 400; + reply_str = pu_400_rpl; + goto error; } if((!msg->event ) ||(msg->event->body.len<=0)) { LM_ERR("Missing event header field value\n"); - return -1; + reply_code = 400; + reply_str = pu_400_rpl; + goto error; } if( msg->to==NULL || msg->to->body.s==NULL) { LM_ERR("cannot parse TO header\n"); - return -1; + reply_code = 400; + reply_str = pu_400_rpl; + goto error; } if(msg->to->parsed != NULL) { @@ -537,6 +548,8 @@ int rls_handle_notify(struct sip_msg* msg, char* c1, char* c2) if(TO.uri.len <= 0) { LM_ERR(" 'To' header NOT parsed\n"); + reply_code = 400; + reply_str = pu_400_rpl; goto error; } pto = &TO; @@ -546,12 +559,16 @@ int rls_handle_notify(struct sip_msg* msg, char* c1, char* c2) if (pto->tag_value.s==NULL || pto->tag_value.len==0 ) { LM_ERR("to tag value not parsed\n"); + reply_code = 400; + reply_str = pu_400_rpl; goto error; } dialog.from_tag= pto->tag_value; if( msg->callid==NULL || msg->callid->body.s==NULL) { LM_ERR("cannot parse callid header\n"); + reply_code = 400; + reply_str = pu_400_rpl; goto error; } dialog.call_id = msg->callid->body; @@ -559,6 +576,8 @@ int rls_handle_notify(struct sip_msg* msg, char* c1, char* c2) if (!msg->from || !msg->from->body.s) { LM_ERR("cannot find 'from' header!\n"); + reply_code = 400; + reply_str = pu_400_rpl; goto error; } if (msg->from->parsed == NULL) @@ -568,6 +587,8 @@ int rls_handle_notify(struct sip_msg* msg, char* c1, char* c2) if ( parse_from_header( msg )<0 ) { LM_ERR("cannot parse From header\n"); + reply_code = 400; + reply_str = pu_400_rpl; goto error; } } @@ -577,6 +598,8 @@ int rls_handle_notify(struct sip_msg* msg, char* c1, char* c2) if( pfrom->tag_value.s ==NULL || pfrom->tag_value.len == 0) { LM_ERR("no from tag value present\n"); + reply_code = 400; + reply_str = pu_400_rpl; goto error; } dialog.to_tag= pfrom->tag_value; @@ -586,6 +609,8 @@ int rls_handle_notify(struct sip_msg* msg, char* c1, char* c2) if(dialog.event< 0) { LM_ERR("unrecognized event package\n"); + reply_code = 489; + reply_str = pu_489_rpl; goto error; } @@ -628,8 +653,10 @@ int rls_handle_notify(struct sip_msg* msg, char* c1, char* c2) */ if(auth_flag==TERMINATED_STATE) goto done; - LM_ERR("no presence dialog record for non-TERMINATED state uri pres_uri = %.*s watcher_uri = %.*s\n", + LM_INFO("no presence dialog record for non-TERMINATED state uri pres_uri = %.*s watcher_uri = %.*s\n", dialog.pres_uri->len, dialog.pres_uri->s, dialog.watcher_uri->len, dialog.watcher_uri->s); + reply_code = 481; + reply_str = pu_481_rpl; goto error; } @@ -784,6 +811,10 @@ done: return 1; error: + if(slb.freply(msg, reply_code, &reply_str) < 0) + { + LM_ERR("failed sending reply\n"); + } if(res_id!=NULL) { pkg_free(res_id->s);

git:master: modules_k/presence: Presence performance and stability changes

In particular made Kamailio quieter (reduced from ERR to INFO) when a dialog cannot be found in the DB or hash-table. This can happen in normal-ish use and was just too noisy. Example: UA/Proxy Kamailio -------- -------- SUBSCRIBE --> <-- 200 OK <-- NOTIFY 503 (overload) --> Dialog removed from DB ...later... un-SUBSCRIBE --> Error message <-- 481 The error message doesn't really help here and on a busy system floods the logs. --- modules_k/presence/subscribe.c | 173 +++++++++++---------------------------- 1 files changed, 49 insertions(+), 124 deletions(-) diff --git a/modules_k/presence/subscribe.c b/modules_k/presence/subscribe.c index 95f6895..7f40872 100644 --- a/modules_k/presence/subscribe.c +++ b/modules_k/presence/subscribe.c @@ -326,43 +326,11 @@ int insert_subs_db(subs_t* s, int type) int update_subs_db(subs_t* subs, int type) { - db_key_t query_cols[22], update_keys[7];
