[kamailio/kamailio] Possibly adjusting the SDP parser to be more lenient towards scenarios where a stream is being removed/rejected and connection-information "c=" is only available per media (no session-wide "c=") and the removed/rejected stream omits all fields (Issue #3982)

### Description I encountered an issue with a specific device that is receiving a T.38 fax. The call gets established towards the device normally with inband media, then the device requests T.38 media and tries to remove the audio media via sending port 0 in the ReInvite SDP. Also it sends connection-information only on the media level and there is no "c=" on the session level. Reading through the related RFCs and the kamailio code and discussing this on the mailing list, we came to the conclusion that kamailio is doing everything correct as per RFC. Though we were wondering if it would be possible to adjust the parser to be not as strict as it is right now, and allow a missing "c=" line on the media-level if the stream is removed/rejected via port 0, since i see no sense in requiring connection information. Of course we are also in contact with the vendor to hopefully adjust on their side. Here are the related RFCs: 1. RFC8866 5.7 `A session description MUST contain either at least one "c=" line in each media description or a single "c=" line at the session level. It MAY contain a single session-level "c=" line and additional media-level "c=" line(s) per-media-description, in which case the media-level values override the session-level settings for the respective media.` 2. RFC3264 8.2 `Existing media streams are removed by creating a new SDP with the port number for that stream set to zero. The stream description MAY omit all attributes present previously, and MAY list just a single media format.` At first i was especially confused by the RFC3264 8.2 part, since it seemed correct what the device is sending, but if you read carefully and keep the wording for SDP in mind only attributes ("a=") MAY be omitted. So a "c=" line should still be in the SDP for the removed media if it's not included on the session-level. Or do you see this differently? ### Expected behavior Kamailio allows and parses the SDP when there is no session-wide "c=", a media stream is being removed via port zero and there is no "c=" for this media stream and only the remaining media streams include a "c=" line. #### Actual observed behavior Kamailio throws an error when trying to parse the SDP. #### Log Messages ``` <core> [core/parser/sdp/sdp.c:523]: parse_sdp_session(): can't find media IP in the message ``` #### SIP Traffic ``` v=0 o=xmserver 1726638425 1726638427 IN IP4 169.254.1.1 s=xmserver t=0 0 m=audio 0 RTP/AVP 8 m=image 56002 udptl t38 c=IN IP4 169.254.1.1 a=sendrecv a=T38FaxVersion:0 a=T38MaxBitRate:14400 a=T38FaxFillBitRemoval:0 a=T38FaxTranscodingMMR:0 a=T38FaxTranscodingJBIG:0 a=T38FaxRateManagement:transferredTCF a=T38FaxMaxBuffer:200 a=T38FaxMaxDatagram:72 a=T38FaxUdpEC:t38UDPRedundancy ``` ### Possible Solutions ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.8.3 (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**: ``` Debian 12 Linux hostname 6.1.0-20-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.85-1 (2024-04-11) x86_64 GNU/Linux ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3982 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] free_fixup functions in cmd_export_t are not called (Issue #3814)
by Xenofon Karamanos 06 Dec '24

06 Dec '24

### Description It seems that the fixup_free_* functions are not getting called when used with: ``` static cmd_export_t cmds[] = { {"acc_log_request", (cmd_function)w_acc_log_request, 1, acc_fixup, free_acc_fixup, ANY_ROUTE}, // ... {0, 0, 0, 0, 0, 0} }; static int free_acc_fixup(void **param, int param_no) { LM_CRIT("acc free fixup = %d\n", param_no); if(*param) { pkg_free(*param); *param = 0; } return 0; } ``` Nothing is getting logged from the function. Is this expected not to print in free_fixup due to the destruction of kamailio and the logging is not reliable? I also used gdb and added some breakpoints in `fixup` and `free_fixup` functions in some other modules (file_out) and the breakpoint was only found in `fixup` but not in `free_fixup`. When is the `free_fixup` supposed to be called, at kamailio destruction or after fixing it and before the main loop starts?  ### Troubleshooting #### Reproduction  Use any module that has a custom (maybe also provided from core) `free_fixup` function, and monitor if `free_fixup` is called using debug mode. #### Log Messages  ``` Apr 15 15:52:03 app01 kamailio[812169]: INFO: <core> [core/mem/q_malloc.c:402]: qm_malloc(): qm_malloc(0x7fcdcab18010, 56) called from file_out: file_out.c: fo_fixup_str_index(287) Apr 15 15:52:03 app01 kamailio[812169]: INFO: <core> [core/mem/q_malloc.c:449]: qm_malloc(): qm_malloc(0x7fcdcab18010, 64) returns address 0x7fcdcacc4280 frag. 0x7fcdcacc4240 (size=64) on 1 -th hit``` `0x7fcdcacc4240` fragment is not found anywhere in the logs reported that it was freed unlike other malloced resources. ``` ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.9.0-dev0 (x86_64/linux) 8bc64a 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: 8bc64a compiled on 15:32:09 Apr 15 2024 with gcc 10.5.0 ``` * **Operating System**:  ``` No LSB modules are available.

[kamailio/kamailio] Allow single quotes in From name (Issue #3984)
by ThomasSevestre 30 Nov '24

30 Nov '24

### Description `secf_check_sqli_all();` block requests when a single quote is present in From name : ``` From: "O'Reilly" <sip:100@example.net>;tag=abcd ``` Since single quotes are frequent in names. It makes it difficult to use this function. ### Possible Solutions A solution would be to skip single quote check in From name. I'll write the PR if you are OK with this solution -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3984 You are receiving this because you are subscribed to this thread.

According to standard the URI must be enclosed in <> if a `Display Name` is given, but it may or may NOT if no display name is present. So, if one tries to modify the `from`/`to` header with an initial empty display name and URI that is NOT enclosed in <>, it yields an invalid message. This PR makes sure that if URI was not enclosed in <> and display name is modified, that will wrap URI in <>.

[kamailio/kamailio] BUG: freeing already freed pointer (0x7f19a3edec68), called from tls: tls_init.c with random core dumps (Issue #3205)
by Tim Chubb 08 Nov '24

### Description  Im getting frequent log entries like this: `CRITICAL: <core> [core/mem/q_malloc.c:519]: qm_free(): BUG: freeing already freed pointer (0x7f19a3edec68), called from tls: tls_init.c: ser_free(323), first free tls: tls_init.c: ser_free(323) - ignoring` This on a fresh VM running Ubuntu 22.04 LTS on the 5.6 branch (building latest release tag) As well as that log message being printed on a frequent basis (every 2 to 3 mins) i am experiencing random crashes/restarts of kamailio. Looking at the core dumps tls_init seems to precipitate the core dump. I have tried using both the TLS module, and TLSA, in the case of TLSA to rule out OpenSSL3 being an issue i have tried linking against locally built OpenSSL 3.0.5 and OpenSSL 1.1.1q with identical results I am in the process of repeating the build on Ubuntu 20.04 LTS to rule out weirdness with packages and similar issues i have experienced whilst evaluating 22.04 LTS ### Troubleshooting #### Reproduction  #### Debugging Data  ``` (gdb) bt full #0 __pthread_kill_implementation (no_tid=0, signo=6, threadid=140425701996352) at ./nptl/pthread_kill.c:44 tid = <optimized out> ret = 0 pd = 0x7fb76815b740 old_mask = {__val = {523986010119, 910533066753, 1, 140425395047168, 94230980435360, 0, 5677797456, 140425395047168, 140725986283600, 140425393986269, 94230963279192, 140425395047168, 94230963279402, 7970739754, 140725986283664, 140425394028321}} ret = <optimized out> pd = <optimized out> old_mask = <optimized out> ret = <optimized out> tid = <optimized out> ret = <optimized out> resultvar = <optimized out> resultvar = <optimized out> __arg3 = <optimized out> __arg2 = <optimized out> __arg1 = <optimized out> _a3 = <optimized out> _a2 = <optimized out> _a1 = <optimized out> __futex = <optimized out> resultvar = <optimized out> __arg3 = <optimized out> __arg2 = <optimized out> __arg1 = <optimized out> _a3 = <optimized out> _a2 = <optimized out> _a1 = <optimized out> __futex = <optimized out> __private = <optimized out> __oldval = <optimized out> result = <optimized out> #1 __pthread_kill_internal (signo=6, threadid=140425701996352) at ./nptl/pthread_kill.c:78 No locals. #2 __GI___pthread_kill (threadid=140425701996352, signo=signo@entry=6) at ./nptl/pthread_kill.c:89 No locals. #3 0x00007fb7681a0476 in __GI_raise (sig=sig@entry=6) at ../sysdeps/posix/raise.c:26 ret = <optimized out> #4 0x00007fb7681867f3 in __GI_abort () at ./stdlib/abort.c:79 save_stage = 1 act = {__sigaction_handler = {sa_handler = 0x100000000, sa_sigaction = 0x100000000}, sa_mask = {__val = {140425395047168, 140725986283888, 140425393986269, 140425394365984, 140425394130944, 140425394801736, 5734026312, 140725986283952, 140425394028321, 15624006419995803439, 94230961557227, 94230963279168, 94230963279576, 140425422497024, 13020282480951897856, 72}}, sa_flags = -619194838, sa_restorer = 0x0} sigs = {__val = {32, 13020282480951897856, 140725986284000, 94230961610857, 13546569962021497653, 14189927350396752214, 94230962920532, 0, 94230963279402, 140425394130944, 10, 38654707763, 12, 140425395047168, 32, 1438623432}} #5 0x000055b3dafd8f12 in qm_debug_check_frag (qm=0x7fb755bc1000, f=0x7fb7576ce500, file=0x7fb766123154 "tls: tls_init.c", line=323, efile=0x55b3db17d559 "core/mem/q_malloc.c", eline=511) at core/mem/q_malloc.c:129 p = 0x7fb755ca0b00 __func__ = "qm_debug_check_frag" #6 0x000055b3dafdd788 in qm_free (qmp=0x7fb755bc1000, p=0x7fb7576ce538, file=0x7fb766123154 "tls: tls_init.c", func=0x7fb766124990 <__func__.0> "ser_free", line=323, mname=0x7fb766123150 "tls") at core/mem/q_malloc.c:511 qm = 0x7fb755bc1000 f = 0x7fb7576ce500 size = 24 next = 0x7fb7576ce500 prev = 0x7fb7576ce3f8 __func__ = "qm_free" #7 0x000055b3dafe954e in qm_shm_free (qmp=0x7fb755bc1000, p=0x7fb7576ce538, file=0x7fb766123154 "tls: tls_init.c", func=0x7fb766124990 <__func__.0> "ser_free", line=323, mname=0x7fb766123150 "tls") at core/mem/q_malloc.c:1350 No locals. #8 0x00007fb7660db698 in ser_free (ptr=0x7fb7576ce538, fname=0x7fb765efa6e5 "../crypto/err/err_local.h", fline=88) at tls_init.c:323 __func__ = "ser_free" #9 0x00007fb765d2e907 in ERR_pop_to_mark () from /lib/x86_64-linux-gnu/libcrypto.so.3 No symbol table info available. #10 0x00007fb765d76a42 in ??
