[kamailio/kamailio] SDP filtering issues with sdpops module (#2755)
by Alessio Garzi 03 Aug '21

03 Aug '21

In order to filter some specific codes from the SDP I am using this functions from sdpops module - sdp_keep_codecs_by_name() - sdp_remove_codecs_by_name() - sdp_keep_codecs_by_id - sdp_remove_codecs_by_id and since they use the same code for filtering the problem I am going to describe affects all of them. Let's say I have this data inside my SDP ``` ... a=rtcp-xr:rcvr-rtt=all:10000 stat-summary=loss,dup,jitt,TTL voip-metrics m=audio 7078 RTP/AVPF 96 97 98 0 8 3 9 18 101 99 100 a=rtpmap:96 opus/48000/2 a=fmtp:96 useinbandfec=1 a=rtpmap:97 speex/16000 a=fmtp:97 vbr=on a=rtpmap:98 speex/8000 a=fmtp:98 vbr=on a=fmtp:18 annexb=yes a=rtpmap:101 telephone-event/48000 a=rtpmap:99 telephone-event/16000 a=rtpmap:100 telephone-event/8000 a=rtcp-fb:* trr-int 1000 a=rtcp-fb:* ccm tmmbr m=video 9078 RTP/AVPF 96 97 a=rtpmap:96 VP8/90000 a=rtpmap:97 H264/90000 a=fmtp:97 profile-level-id=42801F a=rtcp-fb:* trr-int 1000 a=rtcp-fb:* ccm tmmbr a=rtcp-fb:96 nack pli a=rtcp-fb:96 nack sli a=rtcp-fb:96 ack rpsi a=rtcp-fb:96 ccm fir a=rtcp-fb:97 nack pli a=rtcp-fb:97 ccm fir ``` The sdp_keep_codecs_by_id (and I assume all other analog filter functions) correctly detects 2 SDP sessions, one for the audio and one for the video. Now, let's say we want to allow only PCMA,PCMU,GSM,telephone-event ( id 8,0,3,100,99,101 ), this means for example that 96 and 97 codecs have to be stripped. For this reason the functions sdp_remove_str_codec_id_attrs() and sdp_remove_str_codec_id() are executed passing the correct id we want to filter. The sdp_remove_str_codec_id_attrs() will then remove the corresponding lines from the SDP but ONLY IF relative to rtpmap and fmtp. This means that a=rtcp* lines will not be filtered even if they are relative to a filtered codec and this is not what the user expects. Interestingly the sdp_remove_str_codec_id_attrs() function delete the lines only if there is a match with the sdp_payload_attr linked list. https://github.com/kamailio/kamailio/blob/758c85a09ebb2848d0fd2ee82c48784b8… This linked list is built at core level and only exposes rtp_payload and fmtp_string as described here. https://github.com/kamailio/kamailio/blob/758c85a09ebb2848d0fd2ee82c48784b8… So, in other words, the sdpops module has no clue of "a=rtcp-fb*" attributes and cannot be implemented to filter them in a neat way. Another issue arises for the "m=video 9078 RTP/AVPF 96 97" line. Here, since we are filtering 96 and 97, the line remains without ids, maybe it would be better to delete the whole line? The final result after applying my filter is the following ``` m=video 23088 RTP/AVPF a=rtcp-fb:* trr-int 1000 a=rtcp-fb:* ccm tmmbr a=rtcp-fb:96 nack pli a=rtcp-fb:96 nack sli a=rtcp-fb:96 ack rpsi a=rtcp-fb:96 ccm fir a=rtcp-fb:97 nack pli a=rtcp-fb:97 ccm fir ``` -- You are receiving this because you are subscribed to this thread.

Overview + + This is a pseudo module that builds TLS module compiled statically + against libssl and libcrypto (from OpenSSL project). Its C code files + simply include the files from TLS module, setting a different module + name. + + It is a replacement for tls module, with the same modparams and + functions. Just replace ' loadmodule "tls.so" ' with ' loadmodule + "tlsa.so" ' and ' modparam("tls", ...) ' with ' modparam("tlsa", ...) + '. See the docs of TLS module for all the details related to its + parameters, functions, rpc commands, variables, ... + + The benefit of this module is having the libssl and libcrypto embedded + in the module object file, thus not sharing the SSL/TLS context with + any other modules that may link indirectly to libssl (e.g., like + http_client that links against libcurl, which uses libssl). In this + way, the initialization of SSL context (e.g., setting shared memory + management functions) by tlsa module does not impact the other modules. + + Another benefit could be the ability to link a specific libssl version + (e.g., using source build), not being bound to the version shipped with + the operating system. + + The drawback is that updates to the libssl done via operating system + upgrades are not reflected in the tlsa module. It has to be recompiled + every time a new libssl version is installed and it is wanted to be + used by tlsa module. + + NOTE: the module is known to work to be compiled with GCC on Linux + (tested on Debian Stable 10.x). Other compilers (e.g., clang, icc) may + not support same static linking options. Also, some operating systems + may provide only dynamic libssl and libcrypto libraries via their + packages. diff --git a/src/modules/tlsa/doc/tlsa.xml b/src/modules/tlsa/doc/tlsa.xml index 75da4b765c..eecc5f9ab1 100644 --- a/src/modules/tlsa/doc/tlsa.xml +++ b/src/modules/tlsa/doc/tlsa.xml @@ -65,6 +65,13 @@ be recompiled every time a new libssl version is installed and it is wanted to be used by tlsa module. </para> + <para> + NOTE: the module is known to work to be compiled with GCC on Linux + (tested on Debian Stable 10.x).
