[kamailio/kamailio] possible memory corruption in sipcapture module (Issue #3835)
by Sven Uhlig 03 Jun '24

03 Jun '24

### Description We send HEP3 data to the UDP listener in kamailio. In this HEP3 data, there are SIP requests and replies. We want to route these SIP messages through `request_route` and `onreply_route`. For this, we use the SipCapture module with the following settings: ``` modparam("sipcapture", "db_url", DBURL) modparam("sipcapture", "capture_on", 1) modparam("sipcapture", "hep_capture_on", 1) modparam("sipcapture", "insert_retries", 0) modparam("sipcapture", "insert_retry_timeout", 0) request_route { xlog("L_INFO", "Got new request ($ci) $rm: $si => $Ri\n"); } onreply_route { xlog("L_INFO", "Got new reply ($ci) $rm: $si => $Ri - Reply Code $rs\n"); } ``` In the past (version kamailio 5.1.x - 5.4.x), this worked as expected. From the logs: ``` 2(8) INFO: <script>: Got new request (7xkVDrAWegvcZl-ACaUb1HWHwiCYhAJR) INVITE: 217.116.121.230 => 172.20.21.4 3(9) INFO: <script>: Got new reply (7xkVDrAWegvcZl-ACaUb1HWHwiCYhAJR) INVITE: 172.20.21.4 => 217.116.121.230 - Reply Code 407 ``` Starting with kamailio 5.5.x, some pseudo variables are broken. From the logs: ``` 1(7) INFO: <script>: Got new request (7xkVDrAWegvcZl-ACaUb1HWHwiCYhAJR) INVITE: 217.116.121.230 => 217.116.121 2(8) INFO: <script>: Got new reply (7xkVDrAWegvcZl-ACaUb1HWHwiCYhAJR) INVITE: 172.20.21.4 => 172.20.21.4 3(9) INFO: <script>: ... ``` As you can see, the `$Ri` in the request is wrong. It looks like the first three octets of the `$si` and the fourth octet is missing entirely. And for the reply: - The `$Ri` is the `$si`. - The line is missing the static text `Reply Code`, the actual reply code. - The next log is on the same line (the new line is gone). (In this case, we simply sent a third HEP3 message.) To my untrained eye this looks like possible memory corruption. ### Troubleshooting #### Reproduction 1. Set up a kamailio 5.8.1 using the attached [kamailio.cfg](https://github.com/kamailio/kamailio/files/15161868/kamailio.… `/usr/sbin/kamailio -E -DD -dd -f "/etc/kamailio/kamailio.cfg"` 2. Send the HEP3 data using [heplify](https://github.com/sipcapture/heplify) `./heplify -t pcap -rf "sipcapture-bug.pcap" -hs localhost:9060 -e -eof-exit` #### Debugging Data #### Log Messages see above #### SIP Traffic see attached [sipcapture-bug.pcap](https://github.com/kamailio/kamailio/files/15161698/si… ### Possible Solutions Use kamailio 5.4.x or earlier versions. ### Additional Information When setting `nonsip_hook` = `1`, then the `$hep(...)` pseudo variables look fine. Unfortunately, we don't know how process the SIP messages after that point. ``` modparam("sipcapture", "nonsip_hook", 1) ... event_route[sipcapture:request] { xlog("L_INFO", "version: $hep(version)\n"); xlog("L_INFO", "src_ipv4: $hep(0x003)\n"); xlog("L_INFO", "dst_ipv4: $hep(0x004)\n"); xlog("L_INFO", "src_proto: $hep(0x007)\n"); xlog("L_INFO", "dst_proto: $hep(0x008)\n"); xlog("L_INFO", "proto: $hep(0x00b)\n"); } ``` * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.8.1 (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, 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: compiled with gcc 12.2.0 ``` Also tested with same error: 5.5.x, 5.6.x, 5.7.x * **Operating System**: ``` # lsb_release -a No LSB modules are available.

[kamailio/kamailio] Crash on shutdown after geoip2.reload (Issue #3861)
by Bastian Triller 03 Jun '24

03 Jun '24

### Description Kamailio crashes on shutdown in `geoip2_destroy_pv` in `main process` process if geoip2 database was reloaded.  ### Troubleshooting `libmaxminddb.so.0` uses `calloc()` internally to allocate memory for metadata languages and descriptions. On reload via e.g. `ctl` metadata memory is allocated in `ctl` process but `main process` tries to cleanup it. #### Reproduction Load `geoip2` module ``` loadmodule "geoip2.so" modparam("geoip2", "path", "/path/to/your/geolite2.mmdb") ``` Reload database and stop/restart Kamailio ``` kamcmd geoip2.reload service kamailio restart ```  #### Debugging Data ``` (gdb) bt #0 __pthread_kill_implementation (threadid=<optimized out>, signo=signo@entry=6, no_tid=no_tid@entry=0) at ./nptl/pthread_kill.c:44 #1 0x00007f117bc59e8f in __pthread_kill_internal (signo=6, threadid=<optimized out>) at ./nptl/pthread_kill.c:78 #2 0x00007f117bc0afb2 in __GI_raise (sig=sig@entry=6) at ../sysdeps/posix/raise.c:26 #3 0x00007f117bbf5472 in __GI_abort () at ./stdlib/abort.c:79 #4 0x00007f117bc4e430 in __libc_message (action=action@entry=do_abort, fmt=fmt@entry=0x7f117bd68459 "%s\n") at ../sysdeps/posix/libc_fatal.c:155 #5 0x00007f117bc637aa in malloc_printerr (str=str@entry=0x7f117bd660b1 "free(): invalid pointer") at ./malloc/malloc.c:5660 #6 0x00007f117bc65534 in _int_free (av=<optimized out>, p=<optimized out>, have_lock=have_lock@entry=0) at ./malloc/malloc.c:4435 #7 0x00007f117bc67e8f in __GI___libc_free (mem=<optimized out>) at ./malloc/malloc.c:3385 #8 0x00007f1158e6e454 in free_languages_metadata (mmdb=0x7f11592db390) at ./src/maxminddb.c:1860 #9 free_mmdb_struct (mmdb=0x7f11592db390) at ./src/maxminddb.c:1843 #10 0x00007f1158e708a5 in MMDB_close (mmdb=<optimized out>) at ./src/maxminddb.c:1803 #11 0x00007f1158e7ebc9 in geoip2_destroy_pv () at ./src/modules/geoip2/geoip2_pv.c:567 #12 0x000056094fd5f743 in destroy_modules () at core/sr_module.c:881 #13 0x000056094fbb7910 in cleanup (show_status=show_status@entry=1) at ./src/main.c:587 #14 0x000056094fbb86ad in shutdown_children (show_status=show_status@entry=1, sig=15) at ./src/main.c:735 #15 0x000056094fbb932b in handle_sigs () at ./src/main.c:835 #16 0x000056094fbbf1e9 in main_loop () at ./src/main.c:2002 #17 0x000056094fbb353c in main (argc=<optimized out>, argv=<optimized out>) at ./src/main.c:3256 ``` ``` (gdb) f 8 #8 0x00007f1158e6e454 in free_languages_metadata (mmdb=0x7f11592db390) at ./src/maxminddb.c:1860 1860 FREE_AND_SET_NULL(mmdb->metadata.languages.names); (gdb) p *mmdb $1 = {flags = 1, filename = 0x0, file_size = 652795, file_content = 0x7f1158dcd000 <error: Cannot access memory at address 0x7f1158dcd000>, data_section = 0x7f1158e6c430 <error: Cannot access memory at address 0x7f1158e6c430>, data_section_size = 459, metadata_section = 0x7f1158e6c546 <error: Cannot access memory at address 0x7f1158e6c546>, metadata_section_size = 181, full_record_byte_size = 6, depth = 32, ipv4_start_node = {netmask = 0, node_value = 0}, metadata = {node_count = 108720, record_size = 24, ip_version = 4, database_type = 0x0, languages = {count = 1, names = 0x560951ca6250}, binary_format_major_version = 2, binary_format_minor_version = 0, build_epoch = 1648557301, description = {count = 1, descriptions = 0x560951ca5470}}} (gdb) f 9 #9 free_mmdb_struct (mmdb=0x7f11592db390) at ./src/maxminddb.c:1843 1843 free_languages_metadata(mmdb); (gdb) f 10 #10 0x00007f1158e708a5 in MMDB_close (mmdb=<optimized out>) at ./src/maxminddb.c:1803 1803 void MMDB_close(MMDB_s *const mmdb) { free_mmdb_struct(mmdb); } (gdb) f 11 #11 0x00007f1158e7ebc9 in geoip2_destroy_pv () at ./src/modules/geoip2/geoip2_pv.c:567 567 MMDB_close(_handle_GeoIP); ```  ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` /usr/sbin/kamailio -V version: kamailio 5.8.1 (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, 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: unknown compiled with gcc 12.2.0 ``` * **Operating System**:  ``` cat /etc/os-release PRETTY_NAME="Debian GNU/Linux 12 (bookworm)" NAME="Debian GNU/Linux" VERSION_ID="12" VERSION="12 (bookworm)" VERSION_CODENAME=bookworm ID=debian HOME_URL="https://www.debian.org/" SUPPORT_URL="https://www.debian.org/support" BUG_REPORT_URL="https://bugs.debian.org/" ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3861 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] bad BYE message from endpoint when using topoh in kamailio 5.5.1 (Issue #3853)
by descartin 02 Jun '24

02 Jun '24

### Description we are using version: kamailio 5.5.1 (x86_64/linux) 8aa8df-dirty and we have a setup with 2 kamailio instances. First one is doing topoh, and the second one is supposed to not do it Despite this we do see that some replies the second instance is masking some headers like record route and contact in the 200ok (not in the 180) Besides, seems that when the b-side sends a BYE, kamailio show an error, see in logs part However, in the sip pcap we do see thre BYE like it should be. At least that's what it seems to me i attach you the trace [topoh_bye_bad_message.txt](https://github.com/kamailio/kamailio/files/15324… do you have any idea of what can be the issue?  ### Troubleshooting #### Reproduction  #### Debugging Data  ``` (paste your debugging data here) ``` #### Log Messages  ``` May 15 13:19:42 vqbert-2 /usr/local/kamailio/sbin/kamailio[31824]: ERROR: <core> [core/parser/parse_fline.c:272]: parse_first_line(): parse_first_line: bad message (offset: 54) ��%��QI:19:42 vqbert-2 /usr/local/kamailio/sbin/kamailio[31824]: ERROR: <core> [core/parser/msg_parser.c:748]: parse_msg(): ERROR: parse_msg: message=<BYE �ͥ��ĸ��Ը��ĸ��Ʌ��Ց��!��ᕈ�|�� SIP/2.0 Via: SIP/2.0/UDP 199.244.96.39:5060;TH=ucv;branch=z9hG4bK-524287-1---513df3f6b3057f235eef63c542634016;rport Via: SIP/2.0/UDP 199.244.96.46:5071;rport=5071;branch=z9hG4bK-mx5umw4feykudkd5 Max-Forwards: 69 Route: <sip:79.170.71.169;lr;ftag=11002597000844;did=7842.5393> Route: <sip:79.170.71.168;lr=on;ftag=11002597000844;did=b09.3b49> ��%��QI��ĸ��Ը��ĸ��Ʌ��Ց��!��ᕈ�|�� >��`�!ɉU� Contact: sip:199.244.96.46:5071 To: +233240979290 <sip:+233240979290@79.170.71.168;user=phone>;tag=11002597000844 From: +233307000929 <sip:+233307000929@199.244.96.39.SBC1;user=phone>;tag=W7OXULJ726L2OYQEVKNA____.i Call-ID: Sonoc2Did!!:C9WJ3uq4gtNwMlcfzxFlM.jAkx0J34pvaRgtCt0vPl0EPxFwMJZfWJZfMBy7MP** CSeq: 905 BYE Allow: INVITE, ACK, BYE, CANCEL, INFO, SUBSCRIBE, NOTIFY, REFER, MESSAGE, OPTIONS, UPDATE User-Agent: PortaSIP cisco-GUID: 3592442246-2620412195-1372314391-1317599184 h323-conf-id: 3592442246-2620412195-1372314391-1317599184 Content-Length: 0 TH: uch > May 15 13:19:42 vqbert-2 /usr/local/kamailio/sbin/kamailio[31824]: ERROR: <core> [core/receive.c:377]: receive_msg(): core parsing of SIP message failed (199.244.96.39:5060/1) ``` #### SIP Traffic  ``` No. Time Source Destination Protocol Length Info 17 62.116377 19.24.9.39 10.100.10.169 SIP 1273 Request: BYE sip:127.0.0.8;line=sonoc2did-N6IAzBPfOBVfWmZfWBF7WlN-W.y6Mx14NEt7Nw05NhPQpRaAz4rApx4ZgRVZ9lF6z4WZpFIqH.PXKtexHRgEgEgEgEgEORgEgEgEgEgE | Frame 17: 1273 bytes on wire (10184 bits), 1273 bytes captured (10184 bits) Linux cooked capture Internet Protocol Version 4, Src: 19.24.9.39, Dst: 10.100.10.169 User Datagram Protocol, Src Port: 5060, Dst Port: 5060 Session Initiation Protocol (BYE) Request-Line: BYE sip:127.0.0.8;line=sonoc2did-N6IAzBPfOBVfWmZfWBF7WlN-W.y6Mx14NEt7Nw05NhPQpRaAz4rApx4ZgRVZ9lF6z4WZpFIqH.PXKtexHRgEgEgEgEgEORgEgEgEgEgE SIP/2.0 Method: BYE Request-URI: sip:127.0.0.8;line=sonoc2did-N6IAzBPfOBVfWmZfWBF7WlN-W.y6Mx14NEt7Nw05NhPQpRaAz4rApx4ZgRVZ9lF6z4WZpFIqH.PXKtexHRgEgEgEgEgEORgEgEgEgEgE [Resent Packet: False] Message Header Via: SIP/2.0/UDP 19.24.9.39:5060;branch=z9hG4bK-524287-1---513df3f6b3057f235eef63c542634016;rport Via: SIP/2.0/UDP 19.24.9.46:5071;rport=5071;branch=z9hG4bK-mx5umw4feykudkd5 Max-Forwards: 69 Route: <sip:10.100.10.169;lr;ftag=11002597000844;did=7842.5393> Route: <sip:10.100.10.168;lr=on;ftag=11002597000844;did=b09.3b49> Route: <sip:127.0.0.8;line=sonoc2did-N6IAzBPfOBVfWmZfWBF7WlN-W.y6Mx14NEt7Nw05NhPQpRaAz6fLz4rApx4ZgRVZ9lF6z4WZpFIqH.PXKtexHRgEgEgEgEgEORgEgEgEgEgEzuc1mUpGMEeK3jW5o61Yg.4fWBMLWc**> Contact: sip:19.24.9.46:5071 To: +233240979290 <sip:+233240979290@10.100.10.168;user=phone>;tag=11002597000844 From: +233307000929 <sip:+233307000929@19.24.9.39.SBC1;user=phone>;tag=W7OXULJ726L2OYQEVKNA____.i Call-ID: Sonoc2Did!!:C9WJ3uq4gtNwMlcfzxFlM.jAkx0J34pvaRgtCt0vPl0EPxFwMJZfWJZfMBy7MP** [Generated Call-ID: Sonoc2Did!!:C9WJ3uq4gtNwMlcfzxFlM.jAkx0J34pvaRgtCt0vPl0EPxFwMJZfWJZfMBy7MP**] CSeq: 905 BYE Allow: INVITE, ACK, BYE, CANCEL, INFO, SUBSCRIBE, NOTIFY, REFER, MESSAGE, OPTIONS, UPDATE User-Agent: PortaSIP cisco-GUID: 3592442246-2620412195-1372314391-1317599184 h323-conf-id: 3592442246-2620412195-1372314391-1317599184 Content-Length: 0 ``` ### Possible Solutions  ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` (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/3853 You are receiving this because you are subscribed to this thread.
