[kamailio/kamailio] janssonrpcc: No failover to lower prio server (Issue #3378)

by Alex Hermann

### Description I have 2 jsonrpc servers configured with different prio's. For testing, I have the servers configured to always delay the response to any request by more than the module's timout setting. The (initial) request is sent to the first server. As this one times out, I would expect a retry to go to the second servers, but instead, all retries are sent to the same server. The backup server is never contacted. This makes the whole "prio" system seem a bit useless.  ### Troubleshooting #### Reproduction ``` modparam("janssonrpcc", "server", "conn=test;addr=pc1;port=8081;priority=5;weight=10") modparam("janssonrpcc", "server", "conn=test;addr=pc1;port=8082;priority=5;weight=10") ``` ``` janssonrpc_request("test", "Test.Timeout", '[ { "Timout": 1000} ]', "route=JSONRPC_RESPONSE;retry=10;timeout=1000"); ```  #### Log Messages No useful logs are produced. I verified the described behavior on the jsonrpc server.  ``` 2023-02-23T16:59:34.585346+01:00 pc1 proxy1[340870]: INFO: janssonrpcc [janssonrpc_connect.c:361]: bev_connect(): Connecting to server pc1:8081 for conn rating. 2023-02-23T16:59:34.585420+01:00 pc1 proxy1[340870]: INFO: janssonrpcc [janssonrpc_connect.c:361]: bev_connect(): Connecting to server pc1:8082 for conn rating. 2023-02-23T16:59:34.585446+01:00 pc1 proxy1[340870]: INFO: janssonrpcc [janssonrpc_connect.c:290]: bev_connect_cb(): Connected to host pc1:8081 2023-02-23T16:59:34.585462+01:00 pc1 proxy1[340870]: INFO: janssonrpcc [janssonrpc_connect.c:290]: bev_connect_cb(): Connected to host pc1:8082 2023-02-23T17:05:10.903398+01:00 pc1 proxy1[340870]: WARNING: janssonrpcc [janssonrpc_request.c:247]: schedule_retry(): Number of retries exceeded. Failing request. ``` ### Possible Solutions  Retry in combination with a timeout and prio's is a bit tricky. When do what? Just retrying on the first prio makes the lower prio servers completely useless, while going to the next prio on every retry skips possibly useful high-prio servers and may exhaust the number of candidate servers very fast. Best solution IMHO would be to first try every server in the highest prio, before going to the next prio. Do not do (exponential) backoff between these steps. If there are still retries remaining after that, wrap around to the highest prio with the exponentional backoff delay. With the above, failover considers all servers and failover between servers is fast while not overloading a single server. BTW. If I configure multiple servers per prio, it seems to randomly select one of them for every (re)try. It never selects one form the next prio. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` 5.6.1 ``` * **Operating System**:  ``` (paste your output here) ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3378 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Add support for Linux kernel anyIP feature (Issue #3394)

by mohsen

Hi I have a kimailio box that receives messages from one interface and send it from another interface and I use dispatcher module successfully. Now I assigned an I range to Linux loopback interface through Linux kernel anyip feature. And I can ping the range. ip -4 route add local 192.168.0.0/24 dev lo I want to send messages from source of the ip in this range but kamailio cant do this in the right way. I added this two directives to kamailio.cfg: mhomed=yes ip_free_bind = 1 and when I want to use an ip from the list I use $fs=”udp:192.168.0.120:5060”; With no luck If I use force_send_socket(udp:192.168.0.120:5060); kamailio returns an error bad force_send_socket argument: 192.168.0.120:5060 (kamailio doesn't listen on it) and if I add listen directive for one ip like: listen=udp:192.168.0.120:5060 everything works fine but I want to be able to use any ip from list not just one ip. Thanks. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3394 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

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] Random segmentation fault when using 2-argument variant of 'save' function from IMS Registrar SCSCF module (Issue #3412)

by Przemysław Ołtarzewski

### Description We've been experiencing random Kamailio crashes related to invalid memory access attempts at `0xffff` in `w_save` call, `ims_registrar_scscf_mod.c`: ``` Core was generated by `kamailio -w /home -DD -E -e -f /etc/kamailio/kamailio_scscf.cfg'. Program terminated with signal SIGSEGV, Segmentation fault. #0 0x00007f5be796c452 in w_save (_m=0x7f5beafa5188, _route=0x7f5beaeab988 " \b\361\352[\177", _d=0x7f5be3bf8200 "", mode=0x7f5beafa5188 "4", _cflags=0xffff <error: Cannot access memory at address 0xffff>) at ims_registrar_scscf_mod.c:628 ``` We are running the latest Kamailio 5.6.4 using the official Docker image. ### Analysis We were able to analyze corresponding core dump using `gdb` and determine the cause of those random crashes. It turns out that it is related to calling the `save` function of IMS Registrar SCSCF module with 2 arguments. Example configuration: ``` save("REG_SAR_REPLY", "location"); ``` According to documentation, this call is valid, as `mode` and `flags` parameters are optional: https://kamailio.org/docs/modules/5.6.x/modules/ims_registrar_scscf.html#id… The `save` function is exported in `ims_registrar_scscf_mod.c` as follows: ``` /*! \brief * Exported functions */ static cmd_export_t cmds[] = { {"save", (cmd_function) w_save, 2, assign_save_fixup3_async, 0, REQUEST_ROUTE | ONREPLY_ROUTE}, {"save", (cmd_function) w_save, 3, assign_save_fixup3_async, 0, REQUEST_ROUTE | ONREPLY_ROUTE}, {"save", (cmd_function) w_save, 4, save_fixup3, free_uint_fixup, REQUEST_ROUTE | ONREPLY_ROUTE}, ... } ``` And implemented as: ``` /*! \brief * Wrapper to save(location) */ static int w_save(struct sip_msg* _m, char* _route, char* _d, char* mode, char* _cflags) { if(_cflags){ return save(_m, _d, _route, ((int)(*_cflags))); } return save(_m, _d, _route, 0); } ``` Using the 2-argument `save` variant in configuration effectively causes the `w_save` to be called from `src/core/action.c :: do_action` via a 3-argument function-pointer cast: ``` case MODULE2_T: MODF_CALL(cmd_function, h, msg, a->val, (char*)a->val[2].u.data, (char*)a->val[3].u.data ); break; ``` Unfortunately, this cast is inherently unsafe - it leaves the `mode` and `_cflags` undetermined. They are probably effectively bound to some memory area beyond the parameter values of the stack frame corresponding to the function call. Our guess is that incidentally `_cflags == 0x0000` for most of those calls, due to how the stack is structured. But sometimes `_cflags == 0xFFFF` which satisfies the condition in `w_save`, causes `(int)(*_cflags)` dereference attempt and leads to the segmentation fault we've encountered. ### Workaround Based on source code analysis, we have determined that always using `save` with a full set of arguments (including optional ones) will result in `w_save` being called via a 5-argument function pointer, which matches its signature and avoids the issue. Example configuration with workaround applied: ``` save("REG_SAR_REPLY", "location", "0", "0"); ``` After introducing this workaround on target environment we are no longer experiencing the problem. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3412 You are receiving this because you are subscribed to this thread.
