[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] 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.

[kamailio/kamailio] RPC command app_jsdt.reload does not reload "require()" files (Issue #3145)

by Vincent Handfield

### Description If the file loaded with the modparam "load" uses CommonJS modules (Issue #3037-PR #3038), the modules are not reloaded when issuing the command app_jsdt.reload. Only the "main" file is reloaded. #### Reproduction 1 - Start Kamailio with those files as the initial configuration ```generic # kamailio.cfg ## Only the part concerning app_jsdt is included. ## The rest of the config file is ommited for the sake of clarity loadmodule "app_jsdt.so" modparam("app_jsdt", "load", "/etc/kamailio/js/index.js") modparam("app_jsdt", "mode", 1) cfgengine "jsdt" ``` ```js // index.js var myModule = require('./myModule'); function ksr_request_route() { myModule.myFunction() KSR.log("info", "KSR.log called from the index.js file"); } ``` ```js // myModule.js exports.myFunction = function() { KSR.log("info", "KSR.log called from the myModule.js file" } ``` 2 - Modify the myModule.js file ```js // myModule.js exports.myFunction = function() { KSR.log("info", "KSR.log called from the MODIFIED myModule.js file" } ``` 3 - Run the reload command ```console foo@bar:~# kamcmd app_jsdt.reload { old: 0 new: 1 } ``` > Log file > > INFO: app_jsdt [app_jsdt_api.c:1557]: app_jsdt_rpc_reload(): marking for reload js script file: /etc/kamailio/js/index.js (0 => 0) > DEBUG: app_jsdt [app_jsdt_api.c:534]: jsdt_kemi_reload_script(): reloading js script file: /etc/kamailio/js/index.js (0 => 1) 4 - The log file still show those lines: > Log file > >INFO <core> [core/kemi.c:156]: sr_kemi_core_log(): KSR.log called from the myModule.js file >INFO <core> [core/kemi.c:156]: sr_kemi_core_log(): KSR.log called from the index.js file 5 - Modify the index.js file ```js // index.js var myModule = require('./myModule'); function ksr_request_route() { myModule.myFunction() KSR.log("info", "KSR.log called from the MODIFIED index.js file"); } ``` 6 - Run the reload command ```console foo@bar:~# kamcmd app_jsdt.reload { old: 1 new: 2 } ``` > Log file > > INFO: app_jsdt [app_jsdt_api.c:1557]: app_jsdt_rpc_reload(): marking for reload js script file: /etc/kamailio/js/index.js (0 => 1) > DEBUG: app_jsdt [app_jsdt_api.c:534]: jsdt_kemi_reload_script(): reloading js script file: /etc/kamailio/js/index.js (1 => 2) 7 - The log file now show those lines: > Log file > > INFO <core> [core/kemi.c:156]: sr_kemi_core_log(): KSR.log called from the myModule.js file > INFO <core> [core/kemi.c:156]: sr_kemi_core_log(): KSR.log called from the MODIFIED index.js file 8 - Restart kamailio completly 9 - The log file now show those lines: > Log file > > INFO <core> [core/kemi.c:156]: sr_kemi_core_log(): KSR.log called from the MODIFIED myModule.js file > INFO <core> [core/kemi.c:156]: sr_kemi_core_log(): KSR.log called from the MODIFIED index.js file ### Possible Solutions Sorry, I would really like to provide one, but, as I'm a new Kamailio user, I don't know all the internals yet. ### Additional Information * **Kamailio Version** ```console foo@bar:~# kamailio -v version: kamailio 5.6.0 (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 10.2.1 ``` * **Operating System**: ```console foo@bar:~# lsb_release -a No LSB modules are available.

[kamailio/kamailio] usrloc OPTIONS not tracing with HEP (Issue #3136)

by Luke Escudé

### Description OPTIONS keepalives sent by usrloc are not being traced with HEP/Homer ### Troubleshooting #### Reproduction Module setup: modparam("siptrace", "duplicate_uri","sip:HOMERIP:9060"); modparam("siptrace", "hep_mode_on",1); modparam("siptrace", "trace_to_database",0); modparam("siptrace", "trace_flag",22); modparam("siptrace", "trace_on", 1); modparam("siptrace", "hep_version", 3); modparam("siptrace", "trace_mode", 1) I believe the above setup should duplicate ALL packets to homer, which is working just fine, except for usrloc-generated OPTIONS. The 200 OK from endpoints is showing up just fine, just not the initial request. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3136 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Add file support to user blocklist for feeding caller numbers list (Issue #3132)

by soroshsabz

ITNOA ### Description I think for non-db deployment of Kamailio it is very useful to add support static data (like another configurations) for caller numbers list in user blocklist module. because if we do not have this feature we cannot use this module in non-db deployment of Kamailio. ### Expected behavior We have a configuration files (like dispatcher file) that contains below information in format of space separated list (like dispatcher file format) ``` +----+----------------+-------------+-----------+-----------+ | id | username | domain | prefix | whitelist | +----+----------------+-------------+-----------+-----------+ | 23 | 49721123456788 | | 1234 | 0 | | 22 | 49721123456788 | | 123456788 | 1 | | 21 | 49721123456789 | | 12345 | 0 | | 20 | 494675231 | | 499034133 | 1 | | 19 | 494675231 | test | 499034132 | 0 | | 18 | 494675453 | test.domain | 49901 | 0 | | 17 | 494675454 | | 49900 | 0 | +----+----------------+-------------+-----------+-----------+ ``` and user blocklist module read this file and load it, and apply this data for blocking call -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3132 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] sdpops: signedness issue w/ sess-version in o= line (Issue #3099)

by Bastian Triller

I incremented sess-version w/ value `2147483648` via `$sdp(sess_version) = -1` as well as `$sdp(sess_version) = 2147483648`. sess-version in SDP should be 2147483649 but is `-1941279658`. ### Troubleshooting [RFC4566 5.2. Origin ("o=")](https://datatracker.ietf.org/doc/html/rfc4566#section-5.2) ``` <sess-version> is a version number for this session description. Its usage is up to the creating tool, so long as <sess-version> is increased when a modification is made to the session data. Again, it is RECOMMENDED that an NTP format timestamp is used. ``` [Wikipedia NTP Timestamps](https://en.wikipedia.org/wiki/Network_Time_Protocol#Timestamps) ``` The 64-bit binary fixed-point timestamps used by NTP consist of a 32-bit part for seconds and a 32-bit part for fractional second, giving a time scale that rolls over every 232 seconds (136 years) and a theoretical resolution of 2−32 seconds (233 picoseconds). NTP uses an epoch of January 1, 1900. Therefore, the first rollover occurs on February 7, 2036.[28][29] ``` #### Reproduction Receive SDP w/ sess-version greater equal 2^31 (2147483648) and increase version via `$sdp(sess-version) = -1` or setting a value greater than 2^31.  #### Log Messages  ``` May 02 06:43:20.578496 debian11 /usr/sbin/kamailio[121163]: DEBUG: {1 2 INVITE 1-121317(a)127.0.0.1} <core> [core/parser/sdp/sdp_helpr_funcs.c:622]: extract_sess_version(): oline(46): >o=user1 53655765 2147483648 IN IP4 127.0.0.1 < May 02 06:43:20.578501 debian11 /usr/sbin/kamailio[121163]: DEBUG: {1 2 INVITE 1-121317(a)127.0.0.1} <core> [core/parser/sdp/sdp_helpr_funcs.c:651]: extract_sess_version(): end 10: >2147483648< May 02 06:43:20.578508 debian11 /usr/sbin/kamailio[121163]: DEBUG: {1 2 INVITE 1-121317(a)127.0.0.1} <core> [core/parser/sdp/sdp_helpr_funcs.c:506]: extract_mediaip(): located IP address [127.0.0.1] in `o=' field May 02 06:43:20.578512 debian11 /usr/sbin/kamailio[121163]: DEBUG: {1 2 INVITE 1-121317(a)127.0.0.1} <core> [core/parser/sdp/sdp_helpr_funcs.c:506]: extract_mediaip(): located IP address [127.0.0.1] in `c=' field May 02 06:43:20.578532 debian11 /usr/sbin/kamailio[121163]: DEBUG: {1 2 INVITE 1-121317(a)127.0.0.1} sdpops [sdpops_mod.c:1918]: sdp_get_sess_version(): sdp_session_num 0 sess-version: 2147483648 May 02 06:43:20.578536 debian11 /usr/sbin/kamailio[121163]: DEBUG: {1 2 INVITE 1-121317(a)127.0.0.1} sdpops [sdpops_mod.c:1923]: sdp_get_sess_version(): sdp_session_num 1 May 02 06:43:20.578576 debian11 /usr/sbin/kamailio[121163]: DEBUG: {1 2 INVITE 1-121317(a)127.0.0.1} sdpops [sdpops_mod.c:1918]: sdp_get_sess_version(): sdp_session_num 0 sess-version: 2147483648 May 02 06:43:20.578581 debian11 /usr/sbin/kamailio[121163]: DEBUG: {1 2 INVITE 1-121317(a)127.0.0.1} sdpops [sdpops_mod.c:1923]: sdp_get_sess_version(): sdp_session_num 1 May 02 06:43:20.578695 debian11 /usr/sbin/kamailio[121163]: DEBUG: {1 2 INVITE 1-121317(a)127.0.0.1} sdpops [sdpops_mod.c:2111]: pv_set_sdp(): res->flags: 24 May 02 06:43:20.578702 debian11 /usr/sbin/kamailio[121163]: DEBUG: {1 2 INVITE 1-121317(a)127.0.0.1} sdpops [sdpops_mod.c:2112]: pv_set_sdp(): PV_TYPE_INT: 16 May 02 06:43:20.578705 debian11 /usr/sbin/kamailio[121163]: DEBUG: {1 2 INVITE 1-121317(a)127.0.0.1} sdpops [sdpops_mod.c:2113]: pv_set_sdp(): PV_VAL_INT: 8 May 02 06:43:20.578708 debian11 /usr/sbin/kamailio[121163]: DEBUG: {1 2 INVITE 1-121317(a)127.0.0.1} sdpops [sdpops_mod.c:2116]: pv_set_sdp(): param.pvn.u.isname.name.n = 1 May 02 06:43:20.578710 debian11 /usr/sbin/kamailio[121163]: DEBUG: {1 2 INVITE 1-121317(a)127.0.0.1} sdpops [sdpops_mod.c:2125]: pv_set_sdp(): do $sdp(sess_version) = -1941279658 May 02 06:43:20.578713 debian11 /usr/sbin/kamailio[121163]: DEBUG: {1 2 INVITE 1-121317(a)127.0.0.1} sdpops [sdpops_mod.c:1918]: sdp_get_sess_version(): sdp_session_num 0 sess-version: 2147483648 May 02 06:43:20.578716 debian11 /usr/sbin/kamailio[121163]: DEBUG: {1 2 INVITE 1-121317(a)127.0.0.1} sdpops [sdpops_mod.c:1923]: sdp_get_sess_version(): sdp_session_num 1 May 02 06:43:20.578750 debian11 /usr/sbin/kamailio[121163]: DEBUG: {1 2 INVITE 1-121317(a)127.0.0.1} sdpops [sdpops_mod.c:1971]: sdp_set_sess_version(): old_sess_version_num: -2147483648 autoincrement: 0 May 02 06:43:20.578756 debian11 /usr/sbin/kamailio[121163]: DEBUG: {1 2 INVITE 1-121317(a)127.0.0.1} sdpops [sdpops_mod.c:1972]: sdp_set_sess_version(): *new_sess_version_num: -1941279658 autoincrement: 0 ``` ### Possible Solutions  ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.5.4 (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 10.2.1 ``` * **Operating System**:  ``` Distributor ID: Debian Description: Debian GNU/Linux 11 (bullseye) Release: 11 Codename: bullseye Linux debian11 5.10.0-13-amd64 #1 SMP Debian 5.10.106-1 (2022-03-17) x86_64 GNU/Linux ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3099 You are receiving this because you are subscribed to this thread.
