Richard Fuchs	e9af9166dc	TT#3881 re-enable selective packet loop check instead of outright rejecting local endpoints advertised by remote clients (to allow for deliberately daisy chaining packet streams), we flag them for checking against actual packet loops as we did before Change-Id: I5652e86e12f3c1c5053ea70b01e8d128ebf47751 (cherry picked from commit `94e3c8f9cb`)	9 years ago
Richard Fuchs	e755683cb2	detect and ignore when local endpoints are advertised by remote clients fixes #65 this also obsoletes the old loop detection Change-Id: I850d81500c45828af2c4d50d80278ec2d599c2a0 (cherry picked from commit 3254278cfd55167fb881cc665328744183773728) (cherry picked from commit `2e5e2ec1b9`)	9 years ago
Eric Green	aea277dbbe	Add a mutex lock for recording to ensure thread safety when writing to pcap	10 years ago
Eric Green	04b71dd2b5	Add back free that fixes memory leak introduced by rebase	10 years ago
Dylan Mikus	fa8146f053	Fixes for recording packet counter - The packet counter was accidentally a pointer, resulting in it incrementing by 8 instead of 1. That is fixed. - Use proper formatting macro for uint64_t printing. - Start PCAP packet indexing at 1 since that is what Wireshark does.	10 years ago
Dylan Mikus	5fe68b9097	Link recording metadata SDP to RTP packet numbers We write out what RTP packet number the SDP came before. When we receive an SDP offer or answer, we write out the RTP packet number that the SDP preceeded. This will let us split the RTP recording PCAP around SDP renegotiation for things like hold/unhold. Also write out whether the SDP was an offer or an answer.	10 years ago
Dylan Mikus	abd953812f	Fixes to match PCAP packets with SDP We want to be able to match up the source and target <IP>:<PORT> with the IP and port info sent in SDP. I adjusted the source and target <IP>:<PORT> we write to the IP and UDP headers in the PCAP file. I added the offer SDP (in addition to the already written answer SDP) to the metadata file. As a consequence of writing out the offer SDP, we will have empty PCAP files and associated metadata files for calls that are never answered. squash! Fixes to match PCAP packets with SDP Added comments detailing the types of endpoint IP/port values we can use.	10 years ago
Dylan Mikus	1cec331d1c	Only turn on or off recording if explicitly specified When we receive an offer or an answer, we will only turn recording on if it contains the "record-call=yes" flag. Likewise, we only turn recording off if it contains the "record-call=no" flag. If no flag is specified, the call keeps its current recording status. It used to be the case that not specifying "record-call=yes" would turn off call recording. This fix is necessary to account for SDP renegotiation during hold/unhold. If the call system sends over another offer during SDP renegotiation to hold and then unhold, we don't want to change recording behavior unless the call system specifically says so.	10 years ago
Dylan Mikus	7acc3239d2	Write out unique ip:port pairs for all streams. We should do some more checking to make sure we're using the correct values for source and destination ip:port pairs.	10 years ago
Dylan Mikus	f516684ade	All RTP packet data for a call goes to one PCAP file. This involved moving all code from fs.(c\|h) to recording.(c\|h). We still spoof packets, so the UDP will look like all monologues are coming over the same port and will probably look like they are all one stream if you look at the PCAP file.	10 years ago
Dylan Mikus	8f6d7c0a16	Logging cleanup and added recording filesystem logging messages. We log errors when filesystem operations fail, among other things.	10 years ago
Dylan Mikus	f36faef417	Code bug fixes and safety checks around error-possible code. Fixes and changes: - Only create the metadata file if the call is being recorded. - Only write to the metadata file if we actually created it (NULL check). - Make sure we have metadata before putting it on the call object - Correctly overwrite recording metadata without leaking memory - Set the no kernalization flag per call instead of for every packet. - Logging cleanup.	10 years ago
Dylan Mikus	7c53e9f95b	Moved file system management and random string code to appropriate files. File system code is now in fs.{h\|c}. This includes: - spool directory setup - metadata file management - pcap file creation and writing Random hex string generation is now in str.h.	10 years ago
Dylan Mikus	7cc801931a	Added metadata string to call struct. This will follow the call around until we destroy the call, at which point the metadata string will be freed.	10 years ago
Dylan Mikus	a714fbc462	Record RTP in PCAP files in the /tmp directory. RTP Engine creates PCAP files for recorded calls on offer answer instead of initial offer. We make up bogus values for the nonessential parts of the PCAP, UDP, and IP headers. We might be able to pull these from other parts of the RTP Engine, but that information was unnecessary for recording calls so they can be recorded to audio files. If you change the packet headers, be really careful about byte order and datatype size!	10 years ago
Eric Green	70eb6b9e81	Record raw RTP to recording files on the filesystem. Pass in "record-call" flag over `rtpengine_offer` or `rtpengine_answer` message. RTP Engine tracks files used to record pcaps and send them back in the response message. Pipes call audio (unencrypted from both ends) to recording files. Sets up file descriptors for local files to dump RTP recordings. A file and a file descriptor per monologue in a call. Recorded streams will be running in user daemon mode, not in kernel mode. This removes first 12 octets from packet to record just the rtp.	10 years ago

Richard Fuchs	d8e1e9f86a	simplify redis CLI options Removes the explicit redis-read-db configuration and reduces the option to one redis DB and one redis write DB. If only the redis DB is configured, then it will be used for all operations. If both are configured, then the redis DB will be used for reading and the write DB will be used for writing (updates).

Richard Fuchs	6d3865b971	Mass update - manual merge of rfuchs/socket-rework branch This brings master up to date with branch `rfuchs/socket-rework` at commit `b1bcc096b7`. The branches have diverged too much for a proper merge, so this is a manual (squashed) merge. The old master before this merge can be found in branch `old-master-before-socket-rework` (commit `82199216b2`). This is a complete rewrite of all socket handling routines. The most important functional change is that sockets aren't indiscriminately bound to INADDR_ANY (or rather in6addr_any), but instead are always bound to their respective local interface address and with the correct address family. Side effects of this are that in multi-homed environments, multiple sockets must be opened (one per interface address and family) which must be taken into account when considering RLIMIT_NOFILE values. As a benefit, this change allows rtpengine to utilize the full UDP port space per interface address, instead of just one port space per machine. The socket abstraction also makes it possible to support RTP over TCP in the future. Change-Id: If6cf4f42136229490186d2d2482fb4fc140c2b53	10 years ago
