[kamailio/kamailio] Using PATH makes nathelper to send the SIP ping to itself (#2011)
by pwakano 13 Jan '24

13 Jan '24

### Description When using the PATH header option to keep track of original Kamailio node that received the REGISTER, if nathelper is also used with SIP ping enabled, the SIP OPTIONS is sent to itself following the PATH header and not sent directly to the destination. The nathelper/user location modules should have a flag similar to the "path_check_local" of the registrar module, which is meant to avoid looping the message to itself in case the next hop pointed by the PATH header is "myself".  ### Troubleshooting #### Reproduction Configure the registrar module to support PATH and before saving the contact info add the PATH header with the local Kamailio information. Also make sure to have the nathelper and usrloc modules configured to send the keepalive SIP OPTIONS to the registered extensions. By the time the SIP OPTIONS is sent, Kamailio sends to itself, then the message has to be loose_route'd to the final destination. This could be avoided by having the nathelper module to identify the next hop is Kamailio itself skipping this destination as a call to "lookup()" does for the registrar module when the flag path_check_local is true.  #### SIP Traffic  172.128.128.10 is the Kamailio IP and 172.128.128.20 is the extension IP ``` 11:51:07.224713 IP (tos 0x60, ttl 64, id 64497, offset 0, flags [none], proto UDP (17), length 518) 172.128.128.10.5060 > 172.128.128.10.5060: SIP, length: 490 OPTIONS sip:345671002@172.128.128.20:5060;rinstance=d1eb3444a5cec5a1;transport=UDP SIP/2.0 Via: SIP/2.0/UDP 172.128.128.10:5060;branch=z9hG4bK2540713 Route: <sip:172.128.128.10:5060;received=sip:172.128.128.20:5060;lr;cluster_node=192.168.156.10:5060> From: sip:sbc@mydomain.com;tag=uloc-5d2e6499-2fb5-1-0-c15309d2 To: sip:345671002@172.128.128.20:5060;rinstance=d1eb3444a5cec5a1;transport=UDP Call-ID: 40ee1573-7506bba3-5e30c05(a)172.128.128.10 CSeq: 1 OPTIONS Content-Length: 0 11:51:07.226132 IP (tos 0x60, ttl 64, id 44359, offset 0, flags [none], proto UDP (17), length 502) 172.128.128.10.5060 > 172.128.128.20.5060: SIP, length: 474 OPTIONS sip:345671002@172.128.128.20:5060;rinstance=d1eb3444a5cec5a1;transport=UDP SIP/2.0 Via: SIP/2.0/UDP 172.128.128.10;branch=z9hG4bKb958.b807e80b742db62504a45220d8f0e974.0 Via: SIP/2.0/UDP 172.128.128.10:5060;branch=z9hG4bK2540713 From: sip:sbc@mydomain.com;tag=uloc-5d2e6499-2fb5-1-0-c15309d2 To: sip:345671002@172.128.128.20:5060;rinstance=d1eb3444a5cec5a1;transport=UDP Call-ID: 40ee1573-7506bba3-5e30c05(a)172.128.128.10 CSeq: 1 OPTIONS Content-Length: 0 11:51:07.303474 IP (tos 0x0, ttl 128, id 10816, offset 0, flags [none], proto UDP (17), length 786) 172.128.128.20.5060 > 172.128.128.10.5060: SIP, length: 758 SIP/2.0 200 OK Via: SIP/2.0/UDP 172.128.128.10;branch=z9hG4bKb958.b807e80b742db62504a45220d8f0e974.0 Via: SIP/2.0/UDP 172.128.128.10:5060;branch=z9hG4bK2540713 Contact: <sip:172.128.128.20:5060> To: <sip:345671002@172.128.128.20:5060;rinstance=d1eb3444a5cec5a1;transport=UDP>;tag=bb0c1f2d From: sip:sbc@mydomain.com;tag=uloc-5d2e6499-2fb5-1-0-c15309d2 Call-ID: 40ee1573-7506bba3-5e30c05(a)172.128.128.10 CSeq: 1 OPTIONS Accept: application/sdp, application/sdp Accept-Language: en Allow: INVITE, ACK, CANCEL, BYE, NOTIFY, REFER, MESSAGE, OPTIONS, INFO, SUBSCRIBE Supported: replaces, norefersub, extended-refer, timer, outbound, path, X-cisco-serviceuri User-Agent: Z 3.15.40006 rv2.8.20 Allow-Events: presence, kpml, talk Content-Length: 0 11:51:07.306821 IP (tos 0x60, ttl 64, id 64570, offset 0, flags [none], proto UDP (17), length 727) 172.128.128.10.5060 > 172.128.128.10.5060: SIP, length: 699 SIP/2.0 200 OK Via: SIP/2.0/UDP 172.128.128.10:5060;branch=z9hG4bK2540713 Contact: <sip:172.128.128.20:5060;alias=172.128.128.20~5060~1> To: <sip:345671002@172.128.128.20:5060;rinstance=d1eb3444a5cec5a1;transport=UDP>;tag=bb0c1f2d From: sip:sbc@mydomain.com;tag=uloc-5d2e6499-2fb5-1-0-c15309d2 Call-ID: 40ee1573-7506bba3-5e30c05(a)172.128.128.10 CSeq: 1 OPTIONS Accept: application/sdp, application/sdp Accept-Language: en Allow: INVITE, ACK, CANCEL, BYE, NOTIFY, REFER, MESSAGE, OPTIONS, INFO, SUBSCRIBE Supported: replaces, norefersub, extended-refer, timer, outbound, path, X-cisco-serviceuri User-Agent: Z 3.15.40006 rv2.8.20 Allow-Events: presence, kpml, talk Content-Length: 0 ``` ### Possible Solutions  Not found. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` # kamailio -v version: kamailio 5.2.2 (x86_64/linux) 67f967 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: 67f967 compiled on 11:40:41 Mar 11 2019 with gcc 4.8.5 ``` * **Operating System**:  ``` # uname -a Linux kamailio-1 3.10.0-514.21.2.el7.x86_64 #1 SMP Tue Jun 20 12:24:47 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux ``` -- You are receiving this because you are subscribed to this thread.

[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] tm remap_503_500 breaks dialogs (#2405)
by geejay101 23 Nov '23

23 Nov '23

### Description Apparently the remapping of 503 to 500 codes in the tm module does also change the to-tag. This behaviour breaks dialogs with yate and therefore calls hang and the 503 remains unacknowledged. Removing to-tags seems to contradict RFC3261 "12 Dialogs A dialog is identified at each UA with a dialog ID, which consists of a Call-ID value, a local tag **and a remote tag**…" Due to the bug the UA cannot identify the dialog the 500 belongs to. Therefore the dialog remains open and Kamailio keeps repeating 500 messages. ### Troubleshooting After disabling the 503 to 500 remapping with modparam("tm", "remap_503_500", 0) dialogs get properly terminated . #### Reproduction 503 to 500 remapping is enabled by default. Inspect the to tags of the incoming 503 and outgoing 500 messages. #### Debugging Data Henning added this comment: Apparently, this is the way the code works: t_reply.c: if (relayed_code==503 && tm_remap_503_500){ /* replace a final 503 with a 500: * generate a "FAKE" reply and a new to_tag (for easier * debugging)*/ ### Possible Solutions Dont change the to-tag ### Additional Information kamailio -v version: kamailio 5.2.3 (x86_64/linux) c36229 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: c36229 compiled on 10:34:54 Jun 13 2019 with gcc 4.8.5 * **Operating System**: CentOS Linux release 7.6.1810 (Core) 3.10.0-957.12.2.el7.x86_64 -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] load_crl takes 90 seconds to complete it execution with crl file size of 4MB !!! (#2312)
by maheshb2487 23 Nov '23

23 Nov '23

### Description Am using Kamailio 5.1.9 version, In my tls.cfg i have one client and server profile, along with default client and server profile. I have crl enabled for the non default client and server profile , the crl file size is 4 MB in my case. I have 22 child tcp process. With this what i observe is load_crl is taking close to 90 seconds to finish its execution and return. ### Expected behavior load_Crl function should not take 90 seconds to complete its execution. probably it should take in the range of 10-15 seconds to complete its execution or even lesser. #### Actual observed behavior load_Crl function is taking 90 seconds to complete its execution. #### Debugging Data It is very clear from the code, its because of this for loop. time taken to complete load_Crl execution is 90 seconds procs_no=get_max_procs(); for(i = 0; i < procs_no; i++) { if (SSL_CTX_load_verify_locations(d->ctx[i], d->crl_file.s, 0) != 1) { ERR("%s: Unable to load certificate revocation list '%s'\n", tls_domain_str(d), d->crl_file.s); TLS_ERR("load_crl:"); return -1; } store = SSL_CTX_get_cert_store(d->ctx[i]); X509_STORE_set_flags(store, X509_V_FLAG_CRL_CHECK | X509_V_FLAG_CRL_CHECK_ALL); } Is there a way this can be enhanced or as per the current kamailio design this is a must to do for each and every profile and its ssl context array list for each process and for every profile. The same logic is seen in other load functions as well, for example load_cert, load_ca_list, load_crl, set_cipher_list, set_verification, set_ssl_options, set_session_cache, ksr_tls_fix_domain, #### Log Messages  ``` (paste your log messages here) ``` #### SIP Traffic  ``` (paste your sip traffic here) ``` ### Possible Solutions Reply from Henning Westerholt on posting this problem to Users Mailing list "But the code could be probably also improved, maybe it is possible to parallelize it. You can open a feature request about it," ### Additional Information Kamailio 5.1.9 version * **Operating System**:  ``` Linux Kernel version : 3.10.0-693.el7.x86_64 Centos version : CentOS Linux release 7.4.1708 (Core) CPU : 2 cores with model name : Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz [root@miv5000 ~]# cat /proc/meminfo MemTotal: 3882076 kB MemFree: 811244 kB MemAvailable: 2320356 kB Openssl verison : OpenSSL 1.0.2k-fips 26 Jan 2017 ``` -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Presence module RPC command to dump active watchers from memory. (#2188)
by VolodyaIvanets 23 Nov '23

23 Nov '23

### Description Explain what you did, what you expected to happen, and what actually happened. I'm looking at using presence module with **subs_db_mode** parameter set to 0-2 where it uses memory to store and query active watchers. I noticed that sometimes Kamailio will throw following message during PUBLISH processesing and it will not generate appropriate NOTIFY for watchers: `DEBUG: presence [notify.c:1234]: publ_notify(): Could not find subs_dialog ` RPC command to dump current active watchers will be helpful during troubleshooting. Currently with **subs_db_mode** set to 0 you can not tell for sure if subsciption already expired or not. And with **subs_db_mode** set to 1 or 2 you can get information from DB with delay. This command will also allow to clarify subscriber _domain_ value which if I understood correctly must match domain from presentity. Thanks a lot! -- 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/2188

[kamailio/kamailio] dialog and dmq in db_mode 2 - dialog_vars entries created and not deleted (#2093)
by Henning Westerholt 23 Nov '23

23 Nov '23

Dialog and DMQ in db_mode 2 - dialog_vars entries created and not deleted. Szenario: two proxies in DMQ synchronization with additional database. Configuration identical on both machines: ``` root@proxy-1:/etc/kamailio# grep dialog kamailio.cfg loadmodule "dialog.so" modparam("dialog", "db_mode", 2) modparam("dialog", "db_update_period", 10) modparam("dialog", "enable_dmq", 1) modparam("dialog", "default_timeout", 60); modparam("dialog", "send_bye", 1) ``` Call is placed on proxy1. Proxy1 handles the call, and synchronize the dialog data to proxy2. Proxy2 is able to list the dialog with kamcmd dlg.list etc.. Proxy2 will not write the dialog into dialog table, but will write the dialog variables to the dialog_var table: ``` root@proxy-2:/etc/kamailio# mysql kamailio MariaDB [kamailio]> select * from dialog; select * from dialog_vars; Empty set (0.00 sec) +----+------------+---------+-------------+---------------------------------+ | id | hash_entry | hash_id | dialog_key | dialog_value | +----+------------+---------+-------------+---------------------------------+ | 9 | 3479 | 1648 | _uac_fu | sip:customer-1@sip.XXXX.net | | 10 | 3479 | 1648 | _uac_funew | sip:batman@XXX.org | | 11 | 3479 | 1648 | _uac_fdp | | | 12 | 3479 | 1648 | _uac_fdpnew | | | 13 | 3479 | 1648 | _uac_to | sip:customer-2@sip.skalatan.net | | 14 | 3479 | 1648 | _uac_tonew | sip:robin@XXX.org | | 15 | 3479 | 1648 | _uac_tdp | | | 16 | 3479 | 1648 | _uac_tdpnew | | +----+------------+---------+-------------+---------------------------------+ 8 rows in set (0.00 sec) ``` Because of this the dialog_vars will grow for every call. In db_mode 1 this dialog_vars entries (and also dialog entries) are not written. I suggest to adapt db_mode 2 with DMQ to the same behaviour. -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] CDP / IMS Diameter Server Module- diameter_request() function fails to send/forward request (#2035)
by Nick 23 Nov '23

23 Nov '23

Hi Kamailio team, I'm attempting to use Kamailio as a Diameter Routing Agent, but I can't seem to get the diameter_request() function to actually _send_ the diameter request, instead I get a warning about no JSON Response: > WARNING: ims_diameter_server [avp_helper.c:341]: addAVPsfromJSON(): No JSON Response Even when relaying received data without modifying it. I posted this issue on the mailing list but have had no responses. Since then I've run a bunch more tests on a few different versions of Kamailio with a few different Diameter peers with the same result. ### Description The IMS Diameter Server Module's[ diameter_request() function](https://www.kamailio.org/docs/modules/devel/modules/ims_diameter_… fails to send, reporting "No JSON Response" even when fed unmodified received data into it. ### Troubleshooting Initially I was trying to use CDP & IMS Diameter Server Module to create & send Diameter messages, I thought my formatting in the message (the Diameter Message (as JSON)) was incorrect. as I was getting: > WARNING: ims_diameter_server [avp_helper.c:341]: addAVPsfromJSON(): No JSON Response When trying to send the request. To rule out my JSON formatting being the issue I configured two Diameter Peers in Kamailio: >From one Diameter peer, I sent a Diameter request to Kamailio. Kamailio is configured to receive the Diameter request, and without modifying the message body ($diameter_request), put that message into the message of the the diameter_request() so as to rule out formatting errors in the message, just a relay of the message, but this also fails to send. I also included a series of checks to confirm the peer to receive the relayed message was online and capable of handling the specified Diameter application, all of which passed. I've defined the peers in the diametercfg.xml config file, and they're all showing as online when I do a "kamcmd cdp.list_peers": FQDN: ims-hss.localdomain Details: { State: I_Open Disabled: False Last used: 0 Applications: { appid:vendorid: 16777216:10415 appid:vendorid: 16777216:4491 appid:vendorid: 16777216:13019 appid:vendorid: 16777216:0 appid:vendorid: 16777217:10415 appid:vendorid: 16777221:10415 } } Here's a simplified version of my event_route[diameter:request], showing I simply receive the diameter request and then try to send it straight back out using the diameter_request() function: ``` event_route[diameter:request]{ xlog("Got diameter message"); diameter_request("ims-hss.localdomain", $diameter_application, $diameter_command, $diameter_request); xlog("Forwarded Diameter Request"); } ``` When tailing syslog I see the "Got diameter message" entry but not the "Forwarded Diameter Request", which suggests it's not getting past the diameter_request(), instead I just see the: > WARNING: ims_diameter_server [avp_helper.c:341]: addAVPsfromJSON(): No JSON Response Packet captures show Kamailio receives the request but never relays it. The source of avp_helper.c shows the warning is called if the length of the JSON is <= 0, but as I'm feeding back out what I've received it shouldn't be 0, an no recent major changes to the source, so I'm stumped as to why it's catching this. I've attached a full copy of the config files below. #### Reproduction I've tried this with a few different Diameter servers, but I can reproduce it with two FreeDIAMETER peers configured in Diameter CDP Config XML, I've also tried with one Kamailio CDP based peer and using xhttp to call the diameter_request() function with the same results. #### Log Messages Copy of relevant SysLog: https://pastebin.com/ZY8z2kd4 ### Additional Information Full Kamailio Config: https://pastebin.com/afgqUfWr Diameter CDP Config XML: https://pastebin.com/bVrBG8mG Relevant Syslog: https://pastebin.com/ZY8z2kd4 Kamcmd cdp.list_peers: https://pastebin.com/cKi4JAHC Kamailio 5.1.2 on Ubuntu 18.04 installed from Repos. -- You are receiving this because you are subscribed to this thread.
