Merge DFSI host changes into master (#63)
2 years ago
Bryan Biedenkapp da2f6130a8 [NOTICE: this commit is *EXPERIMENTAL* and implements *very* early data support, it is expected to be buggy, incomplete or broken] implement VTUN interface (fne0) on the dvmfne (this requires dvmfne to be run as root on Linux system [untested on non-Linux] to create the tun interface); implement VIFace random MAC generation; implement P25 TIA-102.BAEB SCEP ARP (SCEP is always used for conventional data) on dvmfne; refactor P25 packet status bits (this may break things else where, beware!); properly implement P25 status bit flipping on inbound channel activity; implement functionality in the P25 and DMR DataHeader classes to calculate the proper raw PDU frame length; implement dvmfne ARP table creation and maintainence (this is buggy and requires more implementation and test); implement dvmfne VTUN -> PDU and PDU -> VTUN IP traffic forwarding (this is incomplete and requires more implementation and test); correct several issues on dvmhost p25::packet::Data with overlapped buffers;

Bryan Biedenkapp a9bc150da7 add IP address column to RID tables (this is *NOT* used yet, and is for future use);
2 years ago
Bryan Biedenkapp e90350d350 begin implementing some basic SNDCP handling logic (this isn't complete, and this doesn't make SNDCP work *yet*), however until the implementation is complete, this should prevent channels from becoming grant locked (hopefully);
2 years ago
Bryan Biedenkapp f0f1d489d1 add TIA frame types (for future use); remove extraneous handling for DMR and NXDN (these are shut off in the network code, which makes the code in Dfsi pointless to have); remove g_hideMessages and logging from Dfsi class (for P25 this is actually instrumented by the debug flag in the SerialService (and when it exists UDPService) class, no need to duplicate this; add support for "null" modem mode for the SerialService, this allows basic code flow to be tested without any V.24 interface attached to the dvmdfsi instance, a "portType" parameter was added to the configuration file for this, by default it should always be "uart" but for null modem testing it can be set to "null"; add commenting and function definition commenting;

2 years ago
Bryan Biedenkapp f39e8de0e1 refactor PR#55's peer list implementation to utilize a lookup table; add support to peer list implementation, when in whitelist mode to support per peer passwords (techincally this works in blacklist mode but is ... well irrelevant as blacklist mode *rejects* connections from peers in the list file); correct a few issues regarding how NAKs are returned early in the authentication handshake; reformat log messages; fix issue in host voice when regular conventional traffic is sent to a DVRS-enabled channel and legacy group grant is disabled;

Add support for peer blacklist and whitelist (#55)
2 years ago
Bryan Biedenkapp 1de86458a6 fix DVRS unit deregistration issue (units weren't registered properly during GRP_AFF because DVRS doesn't do the typical U_REG); implement 12-hour timeout for unit registrations (this is only applied if the SU in question has *NOT* had *ANY* activity within 12 hours);
2 years ago
Bryan Biedenkapp c8eb52a57d add try {} catch {} around some critical ASIO read calls to prevent application crash (this won't resolve the errors but should prevent application crash); implement support for peer ID list that *always* receives traffic for a TGID regardless of affiliation rules;
2 years ago
Bryan Biedenkapp 6425ec5cd7 add support to properly filter traffic headers and terminators; add support to selectivly block U2U (private) calls from peers;
2 years ago
Bryan Biedenkapp 70600d3fd7 remove deprecated options; ensure we check if a peer is enabled on the FNE before attempting to read/write to it; silence BUGBUG UDP write message;
2 years ago
Bryan Biedenkapp 942a53069b add support to gate GRP_VCH_GRANT messages from going to peers with no affiliations for a TG (if the TG is configured for affiliated only);
2 years ago
Bryan Biedenkapp 75dbc9e025 refactor parrot frame storage; add support to allow parrot responses to go only to the peer for which the parrot call originated;
2 years ago
Bryan Biedenkapp e4aca9fc4f don't register a CC with itself; be more clear in the config YAML that the controlChannel block should be left at defaults for dedicated control channels;

P25 data (#52)
2 years ago
Bryan Biedenkapp e0b6da51fb make the network presence announcment (VC -> CC and CC -> FNE) timing configurable (this value is in seconds); refactor RF channel enumeration, RF channels are now enumerated in their own class ChannelLookup instead of being integrated into AffiliationLookup, this allows the flexibility to update and change channel information at runtime; add support for VC -> CC presence/registration to tell the CC what the REST information is for that VC, this makes the restAddress and restPort entries for the voiceChNo list in the config.yml optional, the only mandatory fields are channelId, channelNo and restPassword;
2 years ago
Bryan Biedenkapp 0f7eabff82 implement support for peers that identify themselves as "conventional" to ignore affiliated talkgroup rules and be able to receive all traffic if the FNE is configured to allow promiscuous operation; implement extremely preliminary support to allow a CC to claim a VC peer, allowing for appropriate grouping of peers for trunked sites;
2 years ago
Bryan Biedenkapp 4d776f6314 add support for DMR T3 adjacent site broadcast;
2 years ago
Bryan Biedenkapp b19c1d5f6a add support for processing CSBK on the FNE; add support to optionally log TSBK and CSBK network events to InfluxDB;
2 years ago
Bryan Biedenkapp 25cb0e7947 fix typo;
2 years ago
Bryan Biedenkapp 96a9ba1c03 implement trunking site preference support for TGIDs, this implements a feature by which TGIDs can be gated to allow affiliation to preferred sites, all other non-preferred sites will DENY affiliation causing the radio to attempt to roam to another site (this is a trunking only feature and does not change conventional operation);
2 years ago
Bryan Biedenkapp 7d1af0235b implement support for reporting activity, diagnostic and call events to an InfluxDB instance;

W3AXL 9675f42db5 added ability to save RID/TGID lookups from the FNE to local files
2 years ago
Bryan Biedenkapp 31ca17449d *BEWARE* this commit alters the RPI_ARM cross-compiler and may break things *BEWARE*; implement support for HTTPS SSL REST API configuration; add contrib binary overlay for the RPI_ARM compiler (to add libssl-dev dependences);
2 years ago
Bryan Biedenkapp 17d69cb950 add support to disable *ALL* passing of P25 ADJ_STS_BCAST from a CFNE instance; properly implement processing of TSDU messages from any peer; implement login flag from CFNEs to identify themselves as external when they are peering;
2 years ago
Bryan Biedenkapp c4ca72581f for performance reasons on very noisy/busy setups that may have *lots* of peers, use of an alternate port to service diagnostic and activity log transfers helps ensure the traffic port doesn't become overloaded with data;
2 years ago
Bryan Biedenkapp c6c1c72f79 institute a hard 250 peer cap on the CFNE for performance, stability and call quality reasons; implement support for the user to configure the connection limit on a CFNE; implement support to resolve a master NAK to a reason on the host;
2 years ago
Bryan Biedenkapp eb57f1b5d8 implement functionality to block traffic to specific peers from specific external peers; use std::string over const char* wherever possible to limit pointer passing; implement support in FrameQueue and RawFrameQueue to bypass the queue and directly send messages to specified peers (useful in some situations for packets to be immediately dispatched vs queuing and batching); chunk RID list transmissions to aid in increasing performance (this will likely also need to be done with the TGID lists in the future as well); refactor transmitting ACL lists to peers into its own spun off thread so we don't block the main network processing loop (and infact, this requires documentation; since at a certain peer size DVM network partitioning should be considered to reduce the number of concurrent peers serviced by any given FNE and to better load balance connections across a network, instead of relying on a singular central FNE); implement /peer/count REST API to simply return the known connected count of peers; disable the forced ACL list update functionality (for now);

W3AXL 26940f0187 updated rid_acl.example.dat for RID alias
2 years ago
Bryan Biedenkapp a707106ea5 for sanity reasons, unless *specifically* required disallowing transmission of ADJ_STS_BCAST to external peers is enabled by default;
2 years ago
Bryan Biedenkapp 98dacab03c refactor RPTL handling slightly to better handle a RPTL condition while the peer state is in connection state 4 (RUNNING); refactor RPTL slightly to better handle non-valid connection states for RPTL (i.e. non-INVALID/CONNECTED, or RUNNING); reword logging messages for clarity; increase default configuration max pings from 5 to 10, this has the effect of making the time out for a peer 50s in total length before the connection is considered stale (for future reference the formula for the timeout is: PingTime * MaxPings = TimeoutInSeconds);
2 years ago
Bryan Biedenkapp 34ae323166 implement option to disable the CFNE from sending P25 ADJ_STS_BCAST to external peers (that is CFNE's the CFNE receiving the ADJ_STS_BCAST is connected to via peers list in the configuration file); add logging around the RPTL NAK condition; don't validate the connection state when performing a connection cleanup for an RPTL NAK; attempt to erase a peer ID from the peer table if during an RPTL the connection is null (this should never happen); correct a bunch if TG validation issues; correct condition where the FNE would try to pass traffic with *both* srcId and dstId 0 (this should never happen on any protocol really, and if there is some scenario that requires it, contact me on Discord please); add more processing for TSDUs to perform TGID checks and other validations;
2 years ago
Bryan Biedenkapp 0e20d4fec0 add separate config option for reporting peer pings to the log; add extra logging around an RPTL NAK condition;
2 years ago
