[kamailio/kamailio] lib: big integers should not be treated as negative ones (#2106)
by Ivan Murashko 08 Dec '23

08 Dec '23

0xffffffff00000000ULL mask does not take into consideration signed 32 bit integers and as result 2147483648 will be stored as -2147483648. Another mask should be used to correct the issue: 0xffffffff80000000ULL. It processes correctly the case of integers that are greater than 2147483647. There are several gdb tests below: (gdb) p ((unsigned long long)2147483648 & 0xffffffff80000000ULL) $1= 2147483648 (gdb) p ((unsigned long long)2147483647 & 0xffffffff80000000ULL) $2 = 0 (gdb) p ((unsigned long long)2147483646 & 0xffffffff80000000ULL) $3 = 0 (gdb) p ((unsigned long long)4147483646 & 0xffffffff80000000ULL) $4 = 2147483648   #### Pre-Submission Checklist    - [ ] Commit message has the format required by CONTRIBUTING guide - [ ] Commits are split per component (core, individual modules, libs, utils, ...) - [ ] Each component has a single commit (if not, squash them into one commit) - [ ] No commits to README files for modules (changes must be done to docbook files in `doc/` subfolder, the README file is autogenerated) #### Type Of Change - [ ] Small bug fix (non-breaking change which fixes an issue) - [ ] New feature (non-breaking change which adds new functionality) - [ ] Breaking change (fix or feature that would change existing functionality) #### Checklist:  - [ ] PR should be backported to stable branches - [ ] Tested changes locally - [ ] Related to issue #XXXX (replace XXXX with an open issue number) #### Description  You can view, comment on, or merge this pull request online at: https://github.com/kamailio/kamailio/pull/2106 -- Commit Summary -- * lib: big integers should not be treated as negative ones -- File Changes -- M src/lib/srdb1/db_ut.c (2) -- Patch Links -- https://github.com/kamailio/kamailio/pull/2106.patch https://github.com/kamailio/kamailio/pull/2106.diff -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] ims_usrloc_pcscf module loads registration records from the db twice (#2809)
by ErhanOnur 23 Nov '23

23 Nov '23

### Description ims_registrar_pcscf module create a process with rank 1 (PROC_SIPINIT) if reginfo flag is open.. This is wrong because it is written that PROC_SIPINIT rank should be given only to the first worker process. ``` #define PROC_SIPINIT 1 /**< First (special) SIP worker - some modules do special processing in this child, like loading db data */ ``` This leads to a problem. ims_usrloc_pcscf loads registration records from the db twice. The codes are demonstrated below. Similar old issue exists here for another module: https://github.com/kamailio/kamailio/issues/975 ### Troubleshooting #### Reproduction  #### Debugging Data  ``` (paste your debugging data here) ``` #### Log Messages  Here are fork operations and their ranks: ``` [root@n5gc-ims-dev src]# cat /usr/src/erhan5.log | grep init_mod_child | grep ims_usrloc_pcscf 0(10662) DEBUG: <core> [core/sr_module.c:845]: init_mod_child(): idx 0 rank -127: ims_usrloc_pcscf [main] 1(10671) DEBUG: <core> [core/sr_module.c:845]: init_mod_child(): idx 1 rank 1: ims_usrloc_pcscf [udp receiver child=0 sock=10.10.12.101:5060 (172.30.65.101:5060)] 3(10673) DEBUG: <core> [core/sr_module.c:845]: init_mod_child(): idx 3 rank 3: ims_usrloc_pcscf [udp receiver child=2 sock=10.10.12.101:5060 (172.30.65.101:5060)] 2(10672) DEBUG: <core> [core/sr_module.c:845]: init_mod_child(): idx 2 rank 2: ims_usrloc_pcscf [udp receiver child=1 sock=10.10.12.101:5060 (172.30.65.101:5060)] 5(10675) DEBUG: <core> [core/sr_module.c:845]: init_mod_child(): idx 5 rank -1: ims_usrloc_pcscf [slow timer] 0(10662) DEBUG: <core> [core/sr_module.c:845]: init_mod_child(): idx 0 rank 0: ims_usrloc_pcscf [main] 6(10679) DEBUG: <core> [core/sr_module.c:845]: init_mod_child(): idx 6 rank -1: ims_usrloc_pcscf [timer] 4(10674) DEBUG: <core> [core/sr_module.c:845]: init_mod_child(): idx 4 rank 4: ims_usrloc_pcscf [udp receiver child=3 sock=10.10.12.101:5060 (172.30.65.101:5060)] 7(10680) DEBUG: <core> [core/sr_module.c:845]: init_mod_child(): idx 7 rank -1: ims_usrloc_pcscf [secondary timer] 8(10686) DEBUG: <core> [core/sr_module.c:845]: init_mod_child(): idx 8 rank 1: ims_usrloc_pcscf [RegInfo Event Processor] 9(10687) DEBUG: <core> [core/sr_module.c:845]: init_mod_child(): idx 9 rank -1: ims_usrloc_pcscf [Dialog Clean Timer] 10(10688) DEBUG: <core> [core/sr_module.c:845]: init_mod_child(): idx 10 rank -2: ims_usrloc_pcscf [ctl handler] 11(10689) DEBUG: <core> [core/sr_module.c:845]: init_mod_child(): idx 11 rank 5: ims_usrloc_pcscf [tcp receiver (generic) child=0] 12(10694) DEBUG: <core> [core/sr_module.c:845]: init_mod_child(): idx 12 rank 6: ims_usrloc_pcscf [tcp receiver (generic) child=1] 13(10695) DEBUG: <core> [core/sr_module.c:845]: init_mod_child(): idx 13 rank 7: ims_usrloc_pcscf [tcp receiver (generic) child=2] 14(10697) DEBUG: <core> [core/sr_module.c:845]: init_mod_child(): idx 14 rank 8: ims_usrloc_pcscf [tcp receiver (generic) child=3] 15(10699) DEBUG: <core> [core/sr_module.c:845]: init_mod_child(): idx 15 rank -4: ims_usrloc_pcscf [tcp main process] ``` #### SIP Traffic  ``` (paste your sip traffic here) ``` ### Possible Solutions  In following code ims_registrar_pcscf module create a process with rank 1 (PROC_SIPINIT) : fork_process(PROC_SIPINIT, "RegInfo Event Processor", 1); ``` static int child_init(int rank) { LM_DBG("Initialization of module in child [%d] \n", rank); if ((subscribe_to_reginfo == 1) && (rank == PROC_MAIN)) { LM_DBG("Creating RegInfo Event Processor process\n"); int pid = fork_process(PROC_SIPINIT, "RegInfo Event Processor", 1); if (pid < 0) return -1; //error if (pid == 0) { if (cfg_child_init()) return -1; //error reginfo_event_process(); } } if (rank == PROC_MAIN || rank == PROC_TCP_MAIN) return 0; if (rank == 1) { /* init stats */ //TODO if parameters are modified via cfg framework do i change them? //update_stat( max_expires_stat, default_registrar_cfg.max_expires ); update_stat( max_contacts_stat, default_registrar_cfg.max_contacts ); update_stat( default_expire_stat, default_registrar_cfg.default_expires ); } /* don't do anything for main process and TCP manager process */ if (rank == PROC_MAIN || rank == PROC_TCP_MAIN) return 0; return 0; } ``` Here is how ims_usrloc_pcscf loads records from db at its child init callback function: ``` if (_rank==PROC_SIPINIT && db_mode!=DB_ONLY) { // if cache is used, populate domains from DB for( ptr=root ; ptr ; ptr=ptr->next) { LM_DBG("Preloading domain %.*s\n", ptr->name.len, ptr->name.s); if (preload_udomain(ul_dbh, ptr->d) < 0) { LM_ERR("child(%d): failed to preload domain '%.*s'\n", _rank, ptr->name.len, ZSW(ptr->name.s)); return -1; } } } ``` ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` it exists at latest version on master branch.

While the locks thus obtained are held, the session can access only the locked tables. ``` or from Mariadb docs ``` While a connection holds an explicit lock on a table, it cannot access a non-locked table. If you try, the following error will be produced: ERROR 1100 (HY000): Table 'tab_name' was not locked with LOCK TABLES ``` ### Additional Information * **Kamailio Version** * ``` Kamailio ver 5.4.5 or 5.6.0 ``` So, maybe need add additional lock for table active_watchers or need take out query select from space LOCK - UNLOCK for resolve this issue? -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Presence not working with Postgresql && subs_db_mode = 3 && notifier_processes != 0 (#2739)
by kageds 23 Nov '23

23 Nov '23

### Description If I set notifier_processes = 0 then BLF (subscribe/notify) works as expected. if I set notifier_processes to anything other than 0 then the initial subscribe works fine but when the device Re-Subscribes due to expiry of the timer I see errors in the kamailio log, the subsequent susbcribe fails and BLF no longer works. ### Troubleshooting #### Reproduction This issue can be easily reproduced just by setting notifier_processes to 1. #### Debugging Data  ``` ``` #### Log Messages ``` ERROR: db_postgres [km_dbase.c:480]: db_postgres_query_lock(): transaction not in progress ERROR: presence [subscribe.c:1708]: get_database_info(): querying subscription dialog INFO: presence [subscribe.c:1129]: handle_subscribe(): getting stored info ``` #### SIP Traffic  ``` [11:28:02.095] TX to x.x.x.x:5060: SUBSCRIBE sip:1005@example.com;transport=udp SIP/2.0 Via: SIP/2.0/UDP y.y.y.y:51761;branch=z9hG4bK271d65c640 661e;rport Contact: <sip:10004@y.y.y.y:51761> Max-Forwards: 70 Route: <sip:x.x.x.x;lr> To: <sip:1005@example.com;transport=udp> From: <sip:10004@example.com>;tag=602c0c864ab45075 Call-ID: 181910a72dc93418 CSeq: 26762 SUBSCRIBE User-Agent: polycomVVX-VVX_400-UA/5.8.5.1256 Event: dialog Accept: application/dialog-info+xml Expires: 600 Supported: Content-Length: 0 [11:28:02.184] RX from x.x.x.x:5060: SIP/2.0 202 OK Via: SIP/2.0/UDP y.y.y.y:51761;branch=z9hG4bK271d65c640 661e;rport=51761;received=y.y.y.y To: <sip:1005@example.com;transport=udp>;tag=f055057275da74fa400fb8f3e0bfdfcf-718a1cd7 From: <sip:10004@example.com>;tag=602c0c864ab45075 Call-ID: 181910a72dc93418 CSeq: 26762 SUBSCRIBE Expires: 600 Contact: <sip:x.x.x.x:5060;transport=udp> Content-Length: 0 [11:28:02.1 ] RX from x.x.x.x:5060: NOTIFY sip:10004@y.y.y.y:51761 SIP/2.0 Record-Route: <sip:x.x.x.x;lr=on;ftag=f055057275da74fa400fb8f3e0bfdfcf-718a1cd7> Via: SIP/2.0/UDP x.x.x.x;branch=z9hG4bK54.4071b642000000000000000000000000.0 To: <sip:10004@example.com>;tag=602c0c864ab45075 From: <sip:1005@example.com>;tag=f055057275da74fa400fb8f3e0bfdfcf-718a1cd7 CSeq: 1 NOTIFY Call-ID: 181910a72dc93418 Content-Length: 266 Max-Forwards: 70 Event: dialog Contact: <sip:x.x.x.x:5060;transport=udp> Subscription-State: active;expires=600 Content-Type: application/dialog-info+xml <?xml version="1.0"?> <dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="1" state="full" entity="sip:1005@example.com"> <dialog id="615293b33c62dec073e05d9421e9f48b" direction="recipient"> <state>terminated</state> </dialog> </dialog-info> [11:28:02.1 ] TX to x.x.x.x:5060: SIP/2.0 200 OK Via: SIP/2.0/UDP x.x.x.x;branch=z9hG4bK54.4071b642000000000000000000000000.0 To: <sip:10004@example.com>;tag=602c0c864ab45075 From: <sip:1005@example.com>;tag=f055057275da74fa400fb8f3e0bfdfcf-718a1cd7 CSeq: 1 NOTIFY Call-ID: 181910a72dc93418 Server: polycomVVX-VVX_400-UA/5.8.5.1256 Content-Length: 0 ...time...time...time...

[kamailio/kamailio] lost: lost_held_dereference do not handles error message (#2724)
by sergey-safarov 23 Nov '23

23 Nov '23

### Description When LIS server failed, then LIS send message like ``` The error response to the request is an error document. The following response shows an example error response. HTTP/1.1 200 OK Server: Example LIS Expires: Tue, 10 Jan 2006 03:49:20 GMT Cache-control: private Content-Type: application/held+xml;charset=utf-8 Content-Length: 182 <?xml version="1.0"?> <error xmlns="urn:ietf:params:xml:ns:geopriv:held" code="locationUnknown"> <message xml:lang="en">Unable to determine location </message> </error> ``` Here is HTTP code is 200. lost_held_dereference now simply check HTTP code and do not check XML body. Expected XML content check for: 1. XML HELD error message 2. check `findServiceResponse` or `presence` element check like it done for `lost_query`. This check is important because PIDF-LO object may be added to the multipart body. And HELD XML error handling prevents error message addition as PDF-LO object. -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Kamailio resets $ru in branch_route context, probably race condition (#2708)
by Henning Westerholt 23 Nov '23

23 Nov '23

### Description Kamailio resets the $ru in a branch_route context, probably due a race condition and/or bug. Scenario: - Calls is established and answered with 404 - Kamailio enters failure_route - failure_route calls t_relay() - branch_route is entered - new branch is created with $ru = $ru; - next operation trying to access content of the $ru fails: Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: pv [pv_core.c:325]: pv_get_ruri_attr(): failed to parse the R-URI ### Troubleshooting Happens on a production system, after upgrade from 5.2.x to 5.3.9. Research regarding similar bugs have not produced something useful so far. #### Reproduction Issue happens less than 10 times a day and so far could not be easily reproduced. #### Debugging Data Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: NOTICE: 7e8bb2ba47f5ccc |-----> Failure Code 404<- Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: *** cfgtrace:failure_route=[Failure] c=[/etc/kamailio/kamailio.cfg] l=1720 a=5 n=route Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: *** cfgtrace:failure_route=[RELAY] c=[/etc/kamailio/kamailio.cfg] l=703 a=16 n=if Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: *** cfgtrace:failure_route=[RELAY] c=[/etc/kamailio/kamailio.cfg] l=699 a=25 n=is_method Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: *** cfgtrace:failure_route=[RELAY] c=[/etc/kamailio/kamailio.cfg] l=702 a=16 n=if Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: *** cfgtrace:failure_route=[RELAY] c=[/etc/kamailio/kamailio.cfg] l=701 a=25 n=t_is_set Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: *** cfgtrace:failure_route=[RELAY] c=[/etc/kamailio/kamailio.cfg] l=701 a=25 n=t_on_branch Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: *** cfgtrace:failure_route=[RELAY] c=[/etc/kamailio/kamailio.cfg] l=707 a=16 n=if Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: *** cfgtrace:failure_route=[RELAY] c=[/etc/kamailio/kamailio.cfg] l=703 a=25 n=is_method Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: *** cfgtrace:failure_route=[RELAY] c=[/etc/kamailio/kamailio.cfg] l=706 a=16 n=if Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: *** cfgtrace:failure_route=[RELAY] c=[/etc/kamailio/kamailio.cfg] l=705 a=25 n=t_is_set Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: *** cfgtrace:failure_route=[RELAY] c=[/etc/kamailio/kamailio.cfg] l=707 a=25 n=t_on_branch_failure Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: *** cfgtrace:failure_route=[RELAY] c=[/etc/kamailio/kamailio.cfg] l=720 a=16 n=if Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: *** cfgtrace:failure_route=[RELAY] c=[/etc/kamailio/kamailio.cfg] l=711 a=25 n=is_method Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: *** cfgtrace:failure_route=[RELAY] c=[/etc/kamailio/kamailio.cfg] l=714 a=16 n=if Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: *** cfgtrace:failure_route=[RELAY] c=[/etc/kamailio/kamailio.cfg] l=713 a=25 n=t_is_set Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: *** cfgtrace:failure_route=[RELAY] c=[/etc/kamailio/kamailio.cfg] l=713 a=25 n=t_on_failure Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: *** cfgtrace:failure_route=[RELAY] c=[/etc/kamailio/kamailio.cfg] l=742 a=16 n=if Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: *** cfgtrace:failure_route=[RELAY] c=[/etc/kamailio/kamailio.cfg] l=720 a=24 n=t_relay Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: *** cfgtrace:branch_route=[MANAGE_BRANCH] c=[/etc/kamailio/kamailio.cfg] l=2142 a=16 n=if Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: *** cfgtrace:branch_route=[MANAGE_BRANCH] c=[/etc/kamailio/kamailio.cfg] l=2135 a=63 n=assign Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: *** cfgtrace:branch_route=[MANAGE_BRANCH] c=[/etc/kamailio/kamailio.cfg] l=2147 a=16 n=if Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: *** cfgtrace:branch_route=[MANAGE_BRANCH] c=[/etc/kamailio/kamailio.cfg] l=2142 a=25 n=is_method Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: *** cfgtrace:branch_route=[MANAGE_BRANCH] c=[/etc/kamailio/kamailio.cfg] l=2142 a=63 n=assign Apr 13 11:44:39 proxy1 /usr/sbin/kamailio[2202]: ERROR: pv [pv_core.c:325]: pv_get_ruri_attr(): failed to parse the R-URI #### Log Messages See cfgtrace logging above. #### SIP Traffic Not easily to provide as its a productive system in a clustered setup. ### Possible Solutions Ideas on how to further debug this error are welcome. ### Additional Information * kamailio 5.3.9 -- You are receiving this because you are subscribed to this thread.
