[kamailio/kamailio] pipelimit module documentation error? (#1671)
by Rogelio Perez 17 Dec '18

17 Dec '18

As reported by Juan Priotti [here](https://lists.kamailio.org/pipermail/sr-users/2017-December/099727.ht… the way pipelimit actually works is: > limit * timer_interval = max req/sec However the [module documentation](https://www.kamailio.org/docs/modules/5.1.x/modules/pipelimi… can be interpreted as: > limit / timer_interval = max req/sec Is this just a documentation error or are we doing something wrong? Thanks. -- You are receiving this because you are subscribed to this thread. Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/1671

[kamailio/kamailio] sqlops blocks startup of kamailio if database unreachable (#1681)
by mihovilkolaric 05 Dec '18

05 Dec '18

### Description I´m using kamailio´s sqlops-module on a postgresql database. If the database server gets unreachable during operation, sqlops detects this and tries to reconnect: ``` 14:40:48.784 WARNING: db_postgres [km_dbase.c:259]: db_postgres_submit_query(): postgres query command failed, connection status 1, error [no connection to the server] 14:40:48.784 DEBUG: db_postgres [km_dbase.c:262]: db_postgres_submit_query(): resetting the connection to postgress server 14:40:48.784 ERROR: db_postgres [km_dbase.c:267]: db_postgres_submit_query(): 0x7f80a8093680 PQsendQuery Error: could not connect to server: Connection refused ``` and finally, when the DB comes up again, succeeds in executing queries: ``` 14:41:39.738 WARNING: db_postgres [km_dbase.c:259]: db_postgres_submit_query(): postgres query command failed, connection status 1, error [SSL connection has been closed unexpectedly] 14:41:39.739 DEBUG: db_postgres [km_dbase.c:262]: db_postgres_submit_query(): resetting the connection to postgress server 14:41:39.810 DEBUG: db_postgres [km_dbase.c:249]: db_postgres_submit_query(): sending query ok: 0x7f80a8093680 (1) ``` So, obviously the module can handle database outages well. But if the DB is already down when kamailio is started, the cyclic reconnect does not work. Instead, kamailio fails to start immediately: ``` 14:57:54.187 CRITICAL: <core> [main.c:1614]: main_loop(): Cannot fork 14:57:54.188 DEBUG: db_postgres [km_pg_con.c:112]: db_postgres_new_connection(): PQconnectdbParams(0x136bfb0) 14:57:54.188 DEBUG: <core> [core/sr_module.c:938]: init_mod_child(): idx 12 rank -1: rtimer [timer] 14:57:54.188 DEBUG: <core> [core/sr_module.c:938]: init_mod_child(): idx 12 rank -1: sqlops [timer] 14:57:54.188 DEBUG: <core> [core/sr_module.c:708]: find_mod_export_record(): found export of <db_bind_api> in module db_postgres [/usr/lib64/kamailio/modules/db_postgres.so] 14:57:54.188 DEBUG: <core> [db.c:209]: db_bind_mod(): using db bind api for db_postgres 14:57:54.188 DEBUG: <core> [db.c:314]: db_do_init2(): connection 0x7f23c0154120 not found in pool 14:57:54.188 DEBUG: db_postgres [km_pg_con.c:56]: db_postgres_new_connection(): db_id = 0x7f23c0154120 14:57:54.188 DEBUG: db_postgres [km_pg_con.c:70]: db_postgres_new_connection(): 0x7f23c0154380=pkg_malloc(80) 14:57:54.188 DEBUG: db_postgres [km_pg_con.c:84]: db_postgres_new_connection(): opening connection: postgres://xxxx:xxxx@xxxxxxxxxxxxxxxxxx 14:57:54.188 DEBUG: db_postgres [km_pg_con.c:112]: db_postgres_new_connection(): PQconnectdbParams(0x13a41e0) 14:57:54.188 ERROR: db_postgres [km_pg_con.c:115]: db_postgres_new_connection(): could not connect to server: Connection refused Is the server running on host "xxxxxxxxxxxx" () and accepting TCP/IP connections on port 5432? 14:57:54.188 ERROR: db_postgres [km_pg_con.c:148]: db_postgres_new_connection(): cleaning up 0x7f23c0154380=pkg_free() 14:57:54.188 ERROR: <core> [db.c:318]: db_do_init2(): could not add connection to the pool 14:57:54.188 ERROR: sqlops [sql_api.c:164]: sql_connect(): failed to connect to the database [cb] 14:57:54.188 ERROR: <core> [core/sr_module.c:942]: init_mod_child(): error while initializing module sqlops (/usr/lib64/kamailio/modules/sqlops.so) (idx: 12 rank: -1 desc: [timer]) 14:57:54.189 ERROR: <core> [core/pt.c:340]: fork_process(): init_child failed for process 12, pid 24036, "timer" 14:57:54.189 CRITICAL: <core> [main.c:1691]: main_loop(): cannot fork timer process 14:57:54.189 ALERT: <core> [main.c:743]: handle_sigs(): child process 24009 exited normally, status=255 14:57:54.190 ALERT: <core> [main.c:743]: handle_sigs(): child process 24010 exited normally, status=255 14:57:54.190 ALERT: <core> [main.c:743]: handle_sigs(): child process 24011 exited normally, status=255 14:57:54.191 ALERT: <core> [main.c:743]: handle_sigs(): child process 24013 exited normally, status=255 14:57:54.191 ALERT: <core> [main.c:743]: handle_sigs(): child process 24015 exited normally, status=255 14:57:54.191 ALERT: <core> [main.c:743]: handle_sigs(): child process 24019 exited normally, status=255 14:57:54.191 ALERT: <core> [main.c:743]: handle_sigs(): child process 24030 exited normally, status=255 14:57:54.192 INFO: <core> [main.c:771]: handle_sigs(): terminating due to SIGCHLD 14:57:54.192 INFO: <core> [main.c:826]: sig_usr(): signal 15 received 14:57:54.192 INFO: <core> [main.c:826]: sig_usr(): signal 15 received ``` #### Reproduction - use kamailio-script with sqlops - stop kamailio - stop database - try to start kamailio #### Log Messages see above ### Additional Information * **Kamailio Version** - output of `kamailio -v` kamailio 5.1.2 (x86_64/linux) * **Operating System**: RHEL 7.4 on x86_64 -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Crash using TLS with many child processes (#1670)
by Adrien Menella 22 Nov '18

22 Nov '18

### Description Started from the [minimal proxy config](https://github.com/kamailio/kamailio/blob/master/misc/examples/mixe…, we tried to run **more than 1** process using TLS, and, unforntunately it crashed. Everything is working fine **using TLS with 1 child**. Everything is working fine with **more than 1 child process without TLS**. To ease the reproduction, we set an env var called `TARGET` at container instanciation, its value is set to a reachable SIP address using TLS (without DNS resolution). To reproduce issue you will need pjsip/pjsua with SSL/TLS enabled: * install OpenSSL (`sudo apt-get install openssl` for ubuntu) * [install pjsip using autoconf](https://trac.pjsip.org/repos/wiki/Getting-Started/Autoconf) * [manually configure TLS support if necessary](https://trac.pjsip.org/repos/wiki/TLS) * [build and install pjsua](https://trac.pjsip.org/repos/wiki/Python_SIP/Build_Install) We've seen on some issues that a low memory allocation could be an issue using TLS, so we are running kamailio using more memory `kamailio -DD -E -M 256 -m 1024` (still crashing). ### Troubleshooting #### Reproduction Here are the steps to reproduce the issue: * start from [Kamailio minimal proxy config](https://github.com/kamailio/kamailio/blob/master/misc/examples/mixe… * enable TLS by adding/uncommenting following lines: ```diff @@ -1,4 +1,5 @@ #!KAMAILIO +#!define WITH_TLS # # Kamailio (OpenSER) SIP Server v5.2 -

[kamailio/kamailio] Wrong QOP value in UAC auth_alg (#1684)
by Sebastian Lauwers 19 Nov '18

19 Nov '18

### Description While trying to setup a handoff to a third party SIP trunk with authentication, I ran into some issues with said authentication. I'm using qop auth on the inbound leg (and `consume_credentials()`), and then UAC to authenticate against the SIP trunk with different credentials. The third party SIP trunk offers qop auth/auth-int. I manually tried to verify the digest that Kamailio was sending, but couldn't. I added some logging to the `auth_alg.c` file, and ran the whole thing again. HA1 is calculated correctly, and so is HA2. However, the final step of the algorithm produced an incorrect value. After further debugging, I realised that the issue comes from https://github.com/kamailio/kamailio/blob/master/src/modules/uac/auth_alg.c…. More specifically, in my case, the value passed on to `MD5Update` is `auth,auth-int`, instead of the simple `auth` I was expecting (uac doesn't support auth-int). ### Troubleshooting #### SIP Traffic I have PCAPs demonstrating the issue and the hack/fix below. I'd rather not post them publicly, however, I am happy to share them privately with Kamailio devs. In essence: ``` -> INVITE sip:12345@someprovider.org:5060;transport=tcp <- 401 Unauthorized WWW-Authenticate: Digest realm="someprovider.org", qop="auth,auth-int", nonce="5BCF48671749b873534dc63e76d5594f3988555f" -> INVITE sip:12345@someprovider.org:5060;transport=tcp Authorization: Digest username="redacted", realm="someprovider.org", nonce="5BCF48671749b873534dc63e76d5594f3988555f", uri="sip:12345@eu.out.didww.com:5060;transport=tcp", qop=auth, nc=00000001, cnonce="2106889321", response="redacted71d4c9ce119dcf3ec56209e", algorithm=MD5 ``` ### Possible Solutions The hack I've used for the time being is to replace: ```c MD5Update(&Md5Ctx, ":", 1); MD5Update(&Md5Ctx, auth->qop.s, auth->qop.len); MD5Update(&Md5Ctx, ":", 1); ``` with: ```c MD5Update(&Md5Ctx, ":auth:", 6); ``` Obviously, I realise this is not the correct fix, but I figured I'd let the experts fix the value of `auth->qop.len`. I can spend more time on this, if required, but I don't know exactly what the "correct" solution is. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.1.6 (x86_64/linux) flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144 MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled with gcc 5.3.1 ``` * **Operating System**: Dockerized version of Kamailio on Ubuntu xenial: ``` kamailio/kamailio:5.1.6-xenial ``` -- You are receiving this because you are subscribed to this thread.
