[kamailio/kamailio] db_cluster module marking mysql connection down on "Illegal mix of collations" failure (Issue #4332)
by Ben Kaufman 14 Sep '25

14 Sep '25

whosgonna created an issue (kamailio/kamailio#4332)  ### Description We received a INVITE with non-ascii characters in the authentication username. The character set and collation of the subscriber table is `latin1` and `latin1_swedish_ci`. This generated the following failure (DB connection names are `primary` and `secondary`): ``` 3(9) ERROR: db_mysql [km_dbase.c:127]: db_mysql_submit_query(): driver error on query: Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8mb4_general_ci,COERCIBLE) for operation '=' (1267) 3(9) ERROR: <core> [lib/srdb1/db_query.c:158]: db_do_query_internal(): error while submitting query 3(9) WARNING: db_cluster [dbcl_api.c:513]: db_cluster_query(): serial operation - failure on cluster [db] (9/0) [primary] 3(9) ERROR: db_mysql [km_dbase.c:127]: db_mysql_submit_query(): driver error on query: Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8mb4_general_ci,COERCIBLE) for operation '=' (1267) 3(9) ERROR: <core> [lib/srdb1/db_query.c:158]: db_do_query_internal(): error while submitting query 3(9) WARNING: db_cluster [dbcl_api.c:513]: db_cluster_query(): serial operation - failure on cluster [db] (8/0) [secondary] 3(9) ERROR: db_cluster [dbcl_api.c:513]: db_cluster_query(): no successful read on cluster [db] 3(9) ERROR: auth_db [authorize.c:180]: get_ha1(): failed to query database 3(9) ERROR: [DIGEST_AUTH 60e4abd540674d4aa8961d380411585e(a)0.0.0.0 INVITE-124524] Generic failure in authentication. Send '503 Server Error' and exit. ``` While using the limited character set in the database (and it's associated collation) is questionable, and I don't expect the query to succeed, the issue is that this single query failure is causing the connections to be disabled in the db_cluster. ### Troubleshooting #### Reproduction I haven't tried to reproduce this, but I would assume it's easy to do. I can probably mock it up in docker fairly quickly. As a safety measure, I'll be validating the field with `is_alphanum()` #### Log Messages (as in description) #### SIP Traffic The `Username` in the `Proxy-Authorization` header as "\uFEFF1011". As hex it's: ``` 22 ef bb bf 31 30 31 31 22 ``` ### Possible Solutions  ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 6.0.1 (aarch64/linux) flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, MEM_JOIN_FREE, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT-NOSMP, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_SEND_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 on 18:45:18 Mar 14 2025 with gcc 14.2.0 ``` * **Operating System**:  Container: ``` NAME="Alpine Linux" ID=alpine VERSION_ID=3.21.2 PRETTY_NAME="Alpine Linux v3.21" HOME_URL="https://alpinelinux.org/" BUG_REPORT_URL="https://gitlab.alpinelinux.org/alpine/aports/-/issues" ``` Host: ``` NAME="Amazon Linux" VERSION="2023" ID="amzn" ID_LIKE="fedora" VERSION_ID="2023" PLATFORM_ID="platform:al2023" PRETTY_NAME="Amazon Linux 2023" ANSI_COLOR="0;33" CPE_NAME="cpe:2.3:o:amazon:amazon_linux:2023" HOME_URL="https://aws.amazon.com/linux/" BUG_REPORT_URL="https://github.com/amazonlinux/amazon-linux-2023" ``` Kernel (`uname -a)`: ``` Linux use2apocor01.n.fl.gg 6.1.56-82.125.amzn2023.aarch64 #1 SMP Tue Oct 10 17:03:29 UTC 2023 aarch64 aarch64 aarch64 GNU/Linux ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/4332 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] dispatcher: EWMA formula (Issue #4331)
by Michael Furmur 10 Sep '25

10 Sep '25

furmur created an issue (kamailio/kamailio#4331) have a question about EWMA formula in the `dispatcher` module. [documentation](https://www.kamailio.org/docs/modules/devel/modules/dispatch… for `ds_latency_estimator_alpha` points to this [explanation](https://www.itl.nist.gov/div898/handbook/pmc/section3/pmc324.h… which specifies EWMA formula as: $EWMA_t = \lambda*Y_t + (1 - \lambda) * EWMA_{t-1}$ related code at [`src/modules/dispatcher/dispatch.c`](https://github.com/kamailio/kamailio/blob/master/src/modules/dispatcher/dispatch.c#L3191): ``` static inline void latency_stats_update( ds_latency_stats_t *latency_stats, int latency) { ... /* exponentially weighted moving average */ if(latency_stats->count < 10) { latency_stats->estimate = latency_stats->average; } else { latency_stats->estimate = latency_stats->estimate * ds_latency_estimator_alpha + latency * (1 - ds_latency_estimator_alpha); } ``` so: * `latency_stats->estimate` is $EWMA$, * `ds_latency_estimator_alpha` is $\lambda\$. * `latency` is $Y_t$ looks like `latency_stats->estimate` and `latency` are swapped regarding to the formula and as a result higher `ds_latency_estimator_alpha` will rate old average over the actual latency value and that contradicts both `dispatcher` module documentation and meaning in the referenced formula. i believe that code should be: ``` latency_stats->estimate = latency * ds_latency_estimator_alpha + latency_stats->estimate * (1 - ds_latency_estimator_alpha); ``` could someone verify those observations? will make PR if i am not mistaken. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/4331 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Topos does not unmask Refer-To header in in-dialog Refer request (Issue #4301)
by Matteo 30 Aug '25

30 Aug '25

xadhoom created an issue (kamailio/kamailio#4301)  ### Description When topos receives an in-dialog REFER, it correctly unmask everywhing as expected, but not the Refer-To header, which breaks transfers. ### Troubleshooting #### SIP Traffic  For example, this is the refer from a client: ``` REFER sip:atpsh-685d3cd2-69-2@172.23.42.1;transport=tcp SIP/2.0 Via: SIP/2.0/TCP 172.23.42.1:23045;rport;branch=z9hG4bKlaklhcax Max-Forwards: 70 To: <sip:3338063766@example.voismart.com>;tag=Brcm20gBS5eZe From: "Joe" <sip:1001@example.voismart.com>;tag=xbdlk Call-ID: kpjiixyvombnlkw(a)fedora.fritz.box CSeq: 340 REFER Contact: <sip:1001@172.23.42.1:23045;transport=tcp> Refer-To: <sip:atpsh-685d3cd2-69-4@172.23.42.1;transport=tcp?Replaces=lmhzfrkbucirwbc%40fedora.fritz.box%3bto-tag%3dXDQD403r30jeS%3bfrom-tag%3dtwbnd> Referred-By: "Joe" <sip:1001@example.voismart.com> User-Agent: Twinkle/1.10.3 Content-Length: 0 ``` And this is what exits from topos proxy: ``` REFER sip:3338063766@172.23.42.211:5060;transport=udp SIP/2.0 Via: SIP/2.0/TCP 172.23.42.250;branch=z9hG4bK89f.32493a6f0ee894aad0bf66f581e5053a.0;i=3 Max-Forwards: 69 To: <sip:3338063766@example.voismart.com>;tag=Brcm20gBS5eZe From: "Joe" <sip:1001@example.voismart.com>;tag=xbdlk Call-ID: kpjiixyvombnlkw(a)fedora.fritz.box CSeq: 340 REFER Refer-To: <sip:atpsh-685d3cd2-69-4@172.23.42.1;transport=tcp?Replaces=lmhzfrkbucirwbc%40fedora.fritz.box%3bto-tag%3dXDQD403r30jeS%3bfrom-tag%3dtwbnd> Referred-By: "Joe" <sip:1001@example.voismart.com> User-Agent: Twinkle/1.10.3 Content-Length: 0 Route: <sip:172.23.42.3;transport=tcp;r2=on;lr=on;ftag=xbdlk;did=c84.2b02> Route: <sip:172.23.42.3;r2=on;lr=on;ftag=xbdlk;did=c84.2b02> Contact: <sip:btpsh-685d3cd2-69-2@172.23.42.250> ``` ### Possible Solutions Will try to find a solution, I see that in `tps_msg.c` `parse_refer_to.h` is included so perhaps there was some idea about it, but since I'm not an expert in kamailio internals may need some time. ### Additional Information v6.0.x and master -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/4301 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] SIP Race condition when using dlg.end_dlg (Issue #4268)
by IgorG 28 Aug '25

28 Aug '25

IgorrG created an issue (kamailio/kamailio#4268) ### Description We use RPC dlg.end_dlg command to terminate dialog. In most cases it does operate properly and send BYE from kamailio to both sides of dialog (as show on screenshot). ![Image](https://github.com/user-attachments/assets/b49164a5-6442-4c66-bd4d-f5412678247f) We found that in some cases we have only first BYE sent to calling party. Second BYE never sent, when called party tries to terminate call by timeout it get responded with 481. ![Image](https://github.com/user-attachments/assets/10c90b4c-30a3-4123-8e2b-2ca64cdec3c3) ![Image](https://github.com/user-attachments/assets/f0facce8-3acf-4049-8a23-ad559874af7b) In logs we have such warning: мая 27 15:11:46 service-proxy.iqtek.ru kamailio[3518388]: 2(3518388) WARNING: {1 1 BYE 541d3f2c-43fd-43b6-af24-bad1fbf85eb6} dialog [dlg_handlers.c:1343]: dlg_onroute(): unable to find dialog for BYE with route param 'e1e.4f22' [3614:8948] and call-id '541d3f2c-43fd-43b6-af24-bad1fbf85eb6' We also found that in this case this warning shown in logs 0.04 seconds after kamailio receive 200ok. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` # ./kamailio -V version: kamailio 5.8.6 (x86_64/linux) fb71db flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, MEM_JOIN_FREE, 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_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_SEND_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: fb71db compiled on 17:38:27 May 26 2025 with gcc 12.2.0 ``` * **Operating System**: ``` # lsb_release -a No LSB modules are available.

In that case, the S-CSCF exchanges SAR/SAA with the HSS in order to learn the subscription data and the iFC for an unregistered user or for a PSI. The firstflag is necessary to make a distiction between the FAILURE ROUTE that is used for this case and the FAILURE ROUTE that is used for transaction failure towards the AS. The error is, the firstflag is set for the latter case, too, which leads to a wrong handling of communication errors towards the AS. This PR introduces a new function that looks for the old ISCMARK in the lumps of the stored message and hence can make a distinction between the SAR/SAA case and the AS failure case.

[kamailio/kamailio] Dispatcher keepalive change status fault for destinations whit same destination uri and different sockets. (Issue #4330)
by giupand 08 Aug '25

08 Aug '25

giupand created an issue (kamailio/kamailio#4330)  ### Description  Hi, I have a question about the dispatcher OPTIONS keepalive in Kamailio version 5.6.1. I have a dispatcher configuration that probes two destinations with the same destination URI but using different sockets (see the database below), and the OPTIONS keepalive is enabled (status AP). When the first destination (ID 27) goes down, its status changes to IP, and the second destination remains in AP. However, when the second destination (ID 28) goes down, its status remains in AP, and the event_route[dispatcher:dst-down] does not seem to trigger. ``` +----+-------+------------------------+-------+----------+----------------------------------------------------------------------------------------------------------------+----------------+ | id | setid | destination | flags | priority | attrs | description | +----+-------+------------------------+-------+----------+----------------------------------------------------------------------------------------------------------------+----------------+ | 27 | 29 | sip:192.168.2.222:5060 | 2 | 21 | ping_from=sip:27@domain.com;socket=udp:192.168.2.250:5060 | | | 28 | 29 | sip:192.168.2.222:5060 | 2 | 12 | ping_from=sip:28@domain.com;socket=udp:192.168.2.246:5060 | | +----+-------+------------------------+-------+----------+----------------------------------------------------------------------------------------------------------------+----------------+ ``` Wathcing the dispatcher code in Kamailio 5.6.1, I noticed that in the ds_update_state function, there is a loop over the dlist that performs a match on the destination using the input address parameter. ``` int ds_update_state(sip_msg_t *msg, int group, str *address, int state,ds_rctx_t *rctx) [...] while(i < idx->nr) { if(idx->dlist[i].uri.len == address->len && strncasecmp(idx->dlist[i].uri.s, address->s, address->len) == 0) { [...] ``` With the current database configuration, I believe the match is found only for the first entry (ID 27), and not for the second entry (ID 28). **As a result, the status update doesn't seem to work for the second destination.** Is this a bug, or is there something wrong with my configuration? ### Troubleshooting #### Reproduction  #### Debugging Data  ``` (paste your debugging data here) ``` #### Log Messages  ``` (paste your log messages here) ``` #### SIP Traffic  ``` (paste your sip traffic here) ``` ### Possible Solutions  ### Additional Information * **Kamailio Version** - output of `kamailio -v` version: kamailio 5.6.1 (x86_64/linux) flags: USE_TCP, USE_TLS, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, 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_BLOCKLIST, 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. ``` (paste your output here) ``` * **Operating System**:  ``` (paste your output here) ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/4330 You are receiving this because you are subscribed to this thread.
