2019-10-29vty: Permit configuration of ASPs in SCTP client modeHarald Welte2-0/+23
The M3UA specification states that either of the two roles should be the SCTP client and the other the server. It also states that the default for the SGP is to operate as server. However, it permits other configurations. Let's allow this to be configured by the VTY. We need to ensure that while in ASP role, we don't send any NOTIFY messages to the peer SG.

2019-10-29Allow ASP role to be configuredHarald Welte4-6/+34
So far, we had a static role model: * SCTP servers (listening, such as OsmoSTP) are role SGW * SCTP clients (connecting, such as OsmoMSC) are role ASP While this is customary, it is not actually required by the specification. The SGW can establish the SCTP connection to an ASP but still remain "SG" role. Let's make things more flexible by having the role configurable.

2019-10-23vty: ss7: Make sure ASP has at least INET_ANY addr set if not configured in VTYPau Espin Pedrol1-0/+5
Several parts of the code expect an operative ASP to always have at least one local ip addr, be it INET_ANY (NULL, or any specific IP address. This allows osmo_ss7_asp_find_by_socket_addr() matching incoming connectiongs against ASPs defined through VTY "asp" node with no "local-ip" cmd option specified. In that case, we assume the user wants it to bind/match against INET_ANY. Related: OS#3608 Fixes: 80b135581909fef595d48436ab04dbcb147e3895 Change-Id: Id4da0c778890c90cf5bfcf0fd3a7ecf165f2a6df

After this patch, Several "local-ip" and "remote-ip" lines are accepted under "listen" and "asp" VTY nodes, allowing to configure an SCTP connection with multiple connections, hence allowing control of SCTP multi-homing features. libosmo-sccp clients such as osmo-bsc and osmo-msc also gain support for this feature with this commit.

2019-10-22Defer xua server binding until exit of VTY nodePau Espin Pedrol4-44/+3
Commit 10d4815bb1b4b548ec0bc97611b2e7ac45e0ebc5 already fixed the issue where binding was done during L_CS7_XUA_NODE (listen) done, meaning local-ip inside it had no effect. In that comment, binding was moved to happen during "local-ip" VTY cmd. Furthermore, that commit added a new osmo_ss7_bind_all_instances() and related APIs to allow osmo-stp to have all xua servers bound if no "local-ip" was provided. These APIs have only been used so far by osmo-stp (which lays in the same git repo that libosmo-sccp) since it's the only program using the xua server features. In the present commit, let's drop the APIs added by commit described above, and instead let libosmo-sccp code to internally bind the xua server upon exit of the VTY node. As a result, the previously introduced APIs can be dropped (not used by anyone anymore) and it will provide ways to support multiple "local-ip" commands in the future, hence supporting SCTP multi-home features. It's recommended to require libosmocore.git Ia6d88c0e63d94ba99e950da6efbc4c1871070012 since it fixes a bug where go_parent_cb was not called for nodes at the end of the file.
