2019-08-11make it compile with modern Erlang (22.0)HEADmasterHarald Welte2-481/+1
... also do away with our local outdated copy of exprecs and use upstream
2013-09-08make use of local IP address of #sigtran_peer actually workHarald Welte3-18/+23
2013-09-08sctp_core: respect local IP of sigtran peerHarald Welte1-11/+14
when the user specifies an IP in the local #sigtran_peer, we have to bind the socket explicitly to that IP and not let the kernel choose.
2013-09-08ss7_links: make sure IP addresses are canonical before sctp_handlerHarald Welte1-1/+2
2013-09-08permit configuration of links, linksets and routes in app configHarald Welte3-7/+61
Links, Linksets and routes can now be configured in the applicaiton configuration file.
2013-09-08osmo_util: introduce convenience wrappers around application:get_env()Harald Welte1-0/+18
2013-08-27M2UA: Send connect request after ASP_ACTIVATE_ACKHarald Welte1-1/+11
we only snd it once and don't care about the response, this is really only a minimal implementation to test other parts of the system.
2013-08-27MTP3: OPC and DPC elements were switchedHarald Welte1-2/+2
2013-08-27M2UA: Send interface identifier and 'mode override' in ASP_ACTIVE_REQHarald Welte1-1/+3
2013-08-26sctp_m2ua: work as SG and ASP; encode #mtp3_msg{} before handing it to M2UAHarald Welte1-28/+61
2013-08-26xua_codec: convert integer to binary and truncate binary to lengthHarald Welte1-1/+5
2013-08-24m3ua_core: handle 'sctp_paddr_change' eventHarald Welte1-0/+23
This happens e.g. if the route to the peer STP is lost, and we shouldn't crash just because that happens, but rather try to reconnect...
2013-07-27xua_asp_fsm: don't start any timers in 'sg' roleHarald Welte1-1/+1
2013-07-27ss7_link_m2ua: handle_info() is used instead of handle_cast()Harald Welte1-27/+10
handle_cast() is an inherited legacy from old m3ua_core
2013-07-27xua_asp_fsm: match {next_state, X, Y} return value from callback moduleHarald Welte1-4/+3
2013-07-27sctp_m2ua: don't suppress any ASP_UP events from becoming visible to userHarald Welte1-3/+0
2013-07-27remove dead commented out codeHarald Welte1-2/+0
2013-07-27sctp_m2ua: ignore ASP-UP.ind in case of passive/listen modeHarald Welte1-1/+5
2013-07-27xua_asp_fsm: fix typoHarald Welte1-1/+1
2013-07-27xua_asp_fsm: add support for SG mode in addition to existing ASP modeHarald Welte4-36/+105
2013-07-27sctp_core: handle shutdown_comp sctp event.Harald Welte1-0/+1
2013-07-27add ss7_links:role2sctp_role()Harald Welte1-1/+7
helps to translate from asp -> active and sg -> passive
2013-07-27sctp_sua: use 'undefined' for AS PidHarald Welte1-1/+1
2013-07-27sctp_core: register process name and listen to SCTP socket in passive modeHarald Welte1-2/+7
2013-07-27xua_asp_fsm: Only send ASPAS event from ASP to AS if AS pid != undefinedHarald Welte1-1/+6
2013-07-27sctp_sua: Change number of arguments to xua_asp_fsm:init()Harald Welte1-1/+2
In commit eb61885c358100e0e2d73be96f9f83d96422bc3d the number of arguments to xua_asp_fsm:init() was expanded by one for the pid of the AS FSM. This change alters sctp_sua to adhere to this new list of arguments, enen though it passes 'fixme' in as the pid, as we currently don't yet fully use the xua_as_fsm module yet.
2013-07-27hook up the existing m2ua code into the ss7_link infrastructureHarald Welte2-0/+139
After this commit, it is possible to add #sigtran_link{type=m2ua} using the osmo_ss7_sup:add_mtp_link() API. The actual M2UA code appears to be incomplete at this point
2013-06-24isup_codec: add gen_party_number() helperHarald Welte1-1/+33
2013-06-24m3ua_core: handle shutdown_comp SCTP evntHarald Welte1-0/+3
2013-06-13handle non-tuple return value of TupleCBTobias Engel1-4/+9
2013-04-26Fix error in MTP3MG parsing codeHarald Welte1-1/+1
The MTP3MG payload is not the MTP3 payload, but only what is remaining after the MTP3MG header has been parsed.
2012-05-30add xua_asp_test module to repository (was in my local tree only)Harald Welte1-0/+32
2012-05-30make module compile again (m2ua->xua changes)Harald Welte1-29/+51
2012-05-09xua_asp_fsm: Add start_link/6Harald Welte1-1/+4
2012-05-09xua_as_fsm: ignore ASP_DOWN in AS-PENDING and fix state list generationHarald Welte2-3/+18
2012-05-08xua_asp_fsm: wrap next_state/1 and signal ASP state chg to ASHarald Welte1-12/+26
2012-05-08sg_as_sup: introduc get_as_fsm_name/1Harald Welte1-1/+6
2012-05-08xua_as_fsm: fix use of lists:all/2 and introduc create_asp/2Harald Welte1-1/+8
2012-05-07make the SG AS/ASP supervisor hierarchy workHarald Welte4-4/+171
2012-05-06add new AS and ASP supervisors as well as FSM for ASHarald Welte3-0/+314
This is part of a new process hierarchy for proper operation of a SG (Signalling Gateway) with a number of AS, each containing multiple ASP, the respective state management, fail-over, etc. The AS supervisor starts the AS fsm and the ASP supervisor. The ASP supervisor will be used to start and maintain ASP fsm's (xua_asp_fsm), which in turn link into the respective M2UA/M3UA/SUA behavior. Those ASP fsm's will then be used by the processes that represent the SCTP associations.
2012-05-05M2UA Codec: Use generic xUA codec insteadHarald Welte2-68/+5
2012-04-16add compatibility clause for Erlang Public LicenseHarald Welte28-2/+394
This is required to make sure that even if somebody thinks the erlang OTP libraries and my code form a derivative work, there will be no licensing conflict.
2012-04-01rename sua_codec to generic xua_codecHarald Welte4-32/+35
SUA/M3UA/M2UA/M2PA actaully all uses almost the same message format, so it makes sense to write one generic xua_codec and derive from that. The current SUA implementation didn't actually contain anything SUA specific, so we can just rename it and use xua_codec directly from the users.
2012-04-01sua_codec: rename generic part from sua -> xuaHarald Welte1-5/+3
2012-04-01sctp_sua: Pass connectionless msgs to SCCPHarald Welte1-0/+10
2012-02-13remove debug outputHarald Welte1-1/+0
2012-01-31ss7_links: no longer 'link' processes creating a linksetHarald Welte1-10/+14
This just produced bogus messages about cleaning up tables, which was not being done anymore anyway.
2012-01-31osmo_util: add new asn_val() functionHarald Welte1-0/+8
2012-01-28ss7_links: add type annotationsHarald Welte1-14/+53
2012-01-28IPA ss7_link: Construct fake mtp3_routing_label{}Harald Welte1-5/+7
In SCCP-over-IPA links, we don't have MTP3 or something else that can transport a routing label. It's a true point-to-point connection and it cannot do MTP-based routing. In order to fit this into our existing SS7 link / linkset code, we locally construct a fake mtp3 routing label with the remote and local point code of the linkset.
