[kamailio/kamailio] lib: big integers should not be treated as negative ones (#2106)

by Ivan Murashko

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] sslv3 errors showing up with 'tls_method' set as 'TLSv1.2+' (Issue #3085)

by Vinicius K. Ruoso

### Description Some users are having issues connecting to kamailio websocket using TLS. The logs show SSLv3 errors. Cannot find why that error would show up if SSLv2/3 is not enabled. Double checked it via SSLLabs that only TLSv1.2 is allowed in the service. Any pointers would be appreciated. Also, let me know if more debug information is needed. ### Troubleshooting #### Debugging Data This is the TLS config: ``` modparam("tls", "tls_method", "TLSv1.2+") modparam("tls", "verify_certificate", 0) modparam("tls", "require_certificate", 0) modparam("tls", "low_mem_threshold1", 0) modparam("tls", "low_mem_threshold2", 0) modparam("tls", "private_key", "/etc/certs/tls.key") modparam("tls", "certificate", "/etc/certs/tls.crt") ``` This is the output from tls module in kamcmd: ``` kamcmd> tls.info { max_connections: 2048 opened_connections: 353 clear_text_write_queued_bytes: 0 } kamcmd> tls.options { force_run: 0 method: TLSv1.2+ verify_certificate: 0 verify_depth: 9 require_certificate: 0 private_key: /etc/certs/tls.key ca_list: <null string> certificate: /etc/certs/tls.crt cipher_list: <null string> session_cache: 0 session_id: kamailio-tls-5.x.y config: <null string> log: 3 debug: 3 connection_timeout: 600 disable_compression: 1 ssl_release_buffers: -1 ssl_freelist_max: -1 ssl_max_send_fragment: -1 ssl_read_ahead: 0 send_close_notify: 0 low_mem_threshold1: 0 low_mem_threshold2: 0 ct_wq_max: 10485760 con_ct_wq_max: 65536 ct_wq_blk_size: 4096 } ``` #### Log Messages I see this log messages related to SSLv3: ``` 15(36) ERROR: tls [tls_util.h:42]: tls_err_ret(): TLS accept:error:14094416:SSL routines:ssl3_read_bytes:sslv3 alert certificate unknown 15(36) ERROR: <core> [core/tcp_read.c:1512]: tcp_read_req(): ERROR: tcp_read_req: error reading - c: 0x7fafc8768190 r: 0x7fafc8768278 (-1) ``` ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.3.9 (x86_64/linux) flags: USE_TCP, USE_TLS, USE_SCTP, 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_BLACKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED 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 6.3.0 ``` * **Operating System**: Debian 9.13. ``` Linux 4.19.112+ #1 SMP Wed Sep 23 07:53:39 PDT 2020 x86_64 GNU/Linux ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3085 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] No CDR is written on failover (Issue #3254)

by Earn330

Hi, I think there is an issue with writing CDRs on failover scenarios. I have two servers with Kamailio. Both server running Debian 11 (bulleye) and latest Kamailio 5.6.1 from git. I'm using DMQ to sync dialogs and htable between these servers, so both servers have the same knowledge of dialog state. Both Kamailio uses nobind option, so I can switch a VIP from one server to the other one. This is managed with keepalived. Switching the VIP from one server the other one works fine an while a call is running I can switch the VIP. I can see that the BYE Message is handled OK after I made a switch. I can see that acc is triggered but what is missing is acc_cdr in this case. I'm using htable to fill all necessary variables to complete the CDR an I can see that all values are synced correctly. The acc_cdr is created fine if there is no failover so i think it can't be an configuration issue. Both server holds the same Kamailio configuration except the IP. `version: kamailio 5.6.1 (x86_64/linux) bfc5c2-dirty flags: USE_TCP, USE_TLS, USE_SCTP, 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, TLS_PTHREAD_MUTEX_SHARED 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: bfc5c2 -dirty compiled with gcc 10.2.1` `root@voip-lab-proxy01:~# lsb_release -a No LSB modules are available.

[kamailio/kamailio] PUBLISH presence terminated state results in NOTIFY confirmed or early (Issue #3229)

by Duncan Palmer

### Description I established a call between two extensions using TLS, and the presence state was replicated between two Kamailio servers using presence_dmq (no database backing). This all worked correctly except when it comes to sending a PUBLISH with a state terminated in the body, the presence_dmq sent the serialized data correctly, but the Kamailio server sends the wrong state and the caller is marked as busy on all subscribed phones until Kamailio is restarted. This occurs on version 5.6.1. In order generate this data, we use a separate script which responds to Asterisk events and sends the right PUBLISH at the right time to Kamailio, eg. if it sees a Hangup event, it sends a PUBLISH with the state in the body set to 'terminated' and the Expires: header set to 0. This appears to prompt Kamailio to send a NOTIFY with a state of early or confirmed to all subscribers. ### Troubleshooting #### Reproduction Install two Kamailio servers running Kamailio 5.6.1. I am using this installation command: `sudo apt install kamailio=5.6.1+bpo9 kamailio-dbg=5.6.1+bpo9 kamailio-lua-modules=5.6.1+bpo9 kamailio-memcached-modules=5.6.1+bpo9 kamailio-mysql-modules=5.6.1+bpo9 kamailio-presence-modules=5.6.1+bpo9 kamailio-redis-modules=5.6.1+bpo9 kamailio-tls-modules=5.6.1+bpo9 kamailio-utils-modules=5.6.1+bpo9` Some configuration detail for /etc/kamailio/kamailio.cfg: listen=tls:172.22.0.155:5061 # This ensures we have a UDP socket for sending HEP datagrams (we also send the plaintext UDP PUBLISH here) listen=udp:172.22.0.155:9060 port=5061 enable_tls=yes tcp_connection_lifetime=3605 #modules (this is not an exhaustive list) loadmodule "dmq.so" loadmodule "dialog.so" loadmodule "presence.so" loadmodule "presence_xml.so" loadmodule "presence_dialoginfo.so" loadmodule "pua.so" loadmodule "pua_dialoginfo.so" loadmodule "tls.so" modparam("dmq", "server_address", "sip:172.22.0.155:9060") modparam("dmq", "notification_address", "sip:172.22.1.124:9060") modparam("dialog", "db_url", DBURL) modparam("dialog", "enable_stats", 1) modparam("dialog", "db_mode", 0) # 0 - NO_DB - the memory content is not flushed into DB modparam("dialog", "dlg_flag", 9) modparam("dialog", "enable_dmq", 1) modparam("pua", "db_url", DBURL) modparam("pua", "db_mode", 0) # high speed memory based storage modparam("pua", "outbound_proxy", "sips:172.22.0.155:5061;transport=tls") modparam("pua_dialoginfo", "include_localremote", 0) modparam("presence", "db_url", DBURL) modparam("presence", "server_address", "sips:this.host.example.org:5061;transport=tls") modparam("presence", "db_table_lock_type", 0) modparam("presence", "subs_db_mode", 0) # 0 - This disables database completely. modparam("presence", "enable_dmq", 1) modparam("presence", "publ_cache", 2) modparam("presence", "subs_remove_match", 1) modparam("presence", "timeout_rm_subs", 0) modparam("presence_dialoginfo", "force_dummy_dialog", 1) modparam("presence_dialoginfo", "force_single_dialog", 1) modparam("presence_xml", "force_active", 1) modparam("presence_xml", "force_presence_single_body", 1) #### Log Messages These log aren't directly linked but Kamailio reports a 200 OK in response to the PUBLISH, but the NOTIFY to the handset is _not_ terminated. Difficult to capture this because of TLS. ``` Aug 26 13:32:26 this.host.example.org /usr/sbin/kamailio[4187]: DEBUG: presence [presence_dmq.c:467]: pres_dmq_replicate_presentity(): sending serialized data {"action":1,"presentity":{"domain":"sip.prod.example.org","user":"XXXX469","etag":"a.1661495738.4187.2612.0","expires":3600,"recv":1661520746,"event":"dialog"},"t_new":1,"cur_etag":"","ruid":"pres-630869ce-105b-43a","body":"<?xml version=\"1.0\"?>\n<dialog-info xmlns=\"urn:ietf:params:xml:ns:dialog-info\" version=\"0\" state=\"full\" entity=\"sip:XXXX469@sip.prod.example.org\">\n<dialog id=\"c95340dd-5266-450a-8c53-a5cd75c4bb67\" call-id=\"c95340dd-5266-450a-8c53-a5cd75c4bb67\" direction=\"recipient\">\n<state>confirmed</state>\n</dialog>\n</dialog-info>\n"} Aug 26 13:33:00 this.host.example.org /usr/sbin/kamailio[4187]: DEBUG: presence [presence_dmq.c:467]: pres_dmq_replicate_presentity(): sending serialized data {"action":1,"presentity":{"domain":"sip.prod.example.org","user":"XXXX469","etag":"a.1661495738.4187.2622.0","expires":0,"recv":1661520780,"event":"dialog"},"t_new":1,"cur_etag":"","ruid":"pres-630869ce-105b-e3a","body":"<?xml version=\"1.0\"?>\n<dialog-info xmlns=\"urn:ietf:params:xml:ns:dialog-info\" version=\"0\" state=\"full\" entity=\"sip:XXXX469@sip.prod.example.org\">\n<dialog id=\"c95340dd-5266-450a-8c53-a5cd75c4bb67\" call-id=\"c95340dd-5266-450a-8c53-a5cd75c4bb67\" direction=\"recipient\">\n<state>terminated</state>\n</dialog>\n</dialog-info>\n"} ``` This is a similar example: ``` Sep 1 12:37:14 this.host.example.org /usr/sbin/kamailio[5176]: INFO: presence [notify.c:1738]: send_notify_request(): NOTIFY sip:XXXX475@sip.prod.example.org via ÿÿÿÿÿÿÿÿ on behalf of sip:XXXX472@sip.prod.example.org for event dialog : 2_2191795053(a)172.31.29.18 Sep 1 12:37:14 this.host.example.org /usr/sbin/kamailio[5176]: DEBUG: presence [presence_dmq.c:400]: pres_dmq_replicate_presentity(): replicating presentity record - old etag a.1662035772.5176.17.0, new etag , ruid pres-6310a741-1438-11 Sep 1 12:37:14 this.host.example.org /usr/sbin/kamailio[5176]: DEBUG: presence [presence_dmq.c:467]: pres_dmq_replicate_presentity(): sending serialized data {"action":1,"presentity":{"domain":"sip.prod.example.org","user":"XXXX472","etag":"a.1662035772.5176.17.0","expires":0,"recv":1662035834,"event":"dialog"},"t_new":1,"cur_etag":"","ruid":"pres-6310a741-1438-11","body":"<?xml version=\"1.0\"?>\n<dialog-info xmlns=\"urn:ietf:params:xml:ns:dialog-info\" version=\"0\" state=\"full\" entity=\"sip:XXXX472@sip.prod.example.org\">\n<dialog id=\"76024a0e-2d35-47d8-afd1-a1363acbf859\" call-id=\"76024a0e-2d35-47d8-afd1-a1363acbf859\" direction=\"recipient\">\n<state>terminated</state>\n</dialog>\n</dialog-info>\n"} Sep 1 12:37:14 this.host.example.org /usr/sbin/kamailio[5176]: DEBUG: presence [presence_dmq.c:149]: pres_dmq_send(): sending dmq broadcast... ``` #### SIP Traffic ``` PUBLISH sip:XXXX469@sip.prod.example.org SIP/2.0 Via: SIP/2.0/UDP this.host.example.org;branch=656ebca4-5e71-4082-984a-7efa54bdd2cc To: sip:XXXX469@sip.prod.example.org From: sip:XXXX469@sip.prod.example.org;tag=a06f8d92-609b-4210-a1f0-f7042b871f07 CSeq: 12 PUBLISH Call-ID: d67c8bb5-f507-4ada-8f98-d7caa6d86721(a)this.host.example.org Content-Length: 323 User-Agent: Astertisk-Event-Bridge Max-Forwards: 70 Event: dialog Expires: 0 Content-Type: application/dialog-info+xml <?xml version="1.0"?> <dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="0" state="full" entity="sip:XXXX469@sip.prod.example.org"> <dialog id="9fa5bf3c-63f3-4d3f-82c5-cdff374c4e13" call-id="9fa5bf3c-63f3-4d3f-82c5-cdff374c4e13" direction="recipient"> <state>terminated</state> </dialog> </dialog-info> ``` ### Possible Solutions Downgrading to Kamailio version 5.5.4 resolves this problem. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` $ kamailio -v version: kamailio 5.6.1 (x86_64/linux) flags: USE_TCP, USE_TLS, USE_SCTP, 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, TLS_PTHREAD_MUTEX_SHARED 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 6.3.0 $ dpkg -l | egrep '^ii' | grep kamailio | awk '{ print $2, $3 }' kamailio 5.6.1+bpo9 kamailio-dbg:amd64 5.6.1+bpo9 kamailio-lua-modules:amd64 5.6.1+bpo9 kamailio-memcached-modules:amd64 5.6.1+bpo9 kamailio-mysql-modules:amd64 5.6.1+bpo9 kamailio-presence-modules:amd64 5.6.1+bpo9 kamailio-redis-modules:amd64 5.6.1+bpo9 kamailio-tls-modules:amd64 5.6.1+bpo9 kamailio-utils-modules:amd64 5.6.1+bpo9 ``` * **Operating System**: ``` $ lsb_release -a No LSB modules are available.

[kamailio/kamailio] do not generate waring when used UDP protocol and no "Content-Length" header (Issue #3210)

by sergey-safarov

### Description According to [RFC3261](https://datatracker.ietf.org/doc/html/rfc3261#section-20.14) > The Content-Length header field indicates the size of the message- > body, in decimal number of octets, sent to the recipient. > Applications SHOULD use this field to indicate the size of the > message-body to be transferred, regardless of the media type of the > entity. If a stream-based protocol (such as TCP) is used as > transport, the header field MUST be used. When UDP protocol is used then this header is optional. When Kamailio receives an OPTIONS request like in the example, then it floods Kamailio logs with messages like ``` sanity [sanity.c:612]: check_cl(): content length header missing in request ``` OPTIONS message example ``` OPTIONS sip:sbc-0.example.com:5060 SIP/2.0 Via: SIP/2.0/UDP 64.58.61.151:5060;branch=z9hG4bKl7oo3f30a0som61aeu00 Call-ID: 49bc1fcac14b779958dad4b9c43954b400149n2(a)64.58.61.151 To: sip:ping@sbc-0.example.com From: <sip:ping@64.58.61.151>;tag=8fbe5af9178677655bc3a5388c2a8b8c00149n2 Max-Forwards: 70 CSeq: 299694 OPTIONS Route: <sip:3.236.25.4:5060;lr> ``` ### Expected behavior Do not generate warnings about SIP messages that are allowed according to RFC. #### Actual observed behavior Generated warning when "Content-Length" header missing and used UDP protocol. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3210 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] [stirshaken] copy identity header and forward (Issue #3214)

by Artiom Baloian

### Description I am using STIR/SHAKEN as a third party service and wanted to know if there is a function to copy the Identity header from the 302 response into the original INVITE and then forward it. The Contact header from the 302 will make Kamailio server forward the INVITE to the SBC. Ideally having one function which does everything in one place would be a nice feature to have. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3214 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] path & RFC5626: flow-token is not added if +sip.instance and reg-id are missing (Issue #3190)

by space88man

### Description If the INVITE contains `;ob` but no `;+sip.instance=xxxx;reg-id=N` then a flow-token is not added to the record-route header. This is contrary to RFC5626. #### Reproduction Configure 2 x kamailio according to module outbound; i.e 1 x edge proxy and 1 x internal proxy/registrar. UA1 and UA2 have already REGISTER'ed with `;+sip.instance=...;reg-id=...`. ``` UA1, UA2 --- edge proxy --- internal proxy ``` Send INVITE from UA1 to UA2 with `;ob` but no other params: ``` Contact: <sip:user1250@192.168.12.45:5063;transport=TLS;ob> Record-Route: <sip:127.0.0.1;r2=on;lr> Record-Route: <sip:192.168.13.50:5061;transport=tls;r2=on;lr> ``` Observe that there is no flow-token added. Send INVITE from UA1 to UA2 with `;ob` with `;+sip.instance=...;reg-id=...`: ``` Contact: <sip:user1200@192.168.122.15;transport=tls;ob>;+sip.instance="<urn:uuid:0000 `0000-0000-0000-0000-0012341234>";reg-id=7 Record-Route: <sip:Jz0HaDIr1ZoqEAPAqA0yE8XAqAwqyAo=@127.0.0.1;r2=on;lr> Record-Route: <sip:Jz0HaDIr1ZoqEAPAqA0yE8XAqAwqyAo=@192.168.13.50:5061;transport=tls;r2=on;lr> ``` Observe that there is a flow-token added. #### Debugging Data #### SIP Traffic ### Possible Solutions ### Additional Information Version; kamailio 5.6.0 #### RFC5626 Section 9.5 https://datatracker.ietf.org/doc/html/rfc5626#section-9.5 INVITE must contain `ob;` but does not need to contain `;+sip.instance=...;reg-id=...` ``` INVITE sip:alice@a.example SIP/2.0 From: Bob <sip:bob@example.com>;tag=ldw22z To: Alice <sip:alice@a.example> Call-ID: 95KGsk2V/Eis9LcpBYy3 CSeq: 1 INVITE Route: <sip:ep1.example.com;lr> Contact: <sip:bob@192.0.2.2;transport=tcp;ob> ``` EP1 adds a Record-Route with a flow-token in message #43. ``` Record-Route: <sip:3yJEbr1GYZK9cPYk5Snocez6DzO7w+AX@ep1.example.com;lr> ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3190 You are receiving this because you are subscribed to this thread.
