[M] Change in libosmo-sigtran[master]: asp: Support Tx DAUD when ASP becomes activated
by pespin 16 Jul '25

16 Jul '25

pespin has submitted this change. ( https://gerrit.osmocom.org/c/libosmo-sigtran/+/40501?usp=email ) ( 6 is the latest approved patch-set. No files were changed between the latest approved patch-set and the submitted one. )Change subject: asp: Support Tx DAUD when ASP becomes activated ...................................................................... asp: Support Tx DAUD when ASP becomes activated Otherwise the local Signalling Point has no way to know whether the remote Signalling Points it wants to talk to are actually already connected to the STP when it becomes active after the process starts up, unless it attempts to transmit a message to it. This pocedure is documented both for M3UA and SUA: * RFC4666 4.6, RFC3868 4.6 * RFC4666 4.5.3, RFC3868 4.5.3 "ASP Auditing" * RFC4666 5.5.1.1.3 "Support for ASP Querying of SS7 Destination States" The M3UA specs (RFC4666 5.5.1.1.3) explicitly state that the point codes to audit are not to be provided by uppers layers, so picking the ones from the locally configured address book for now: """ Note: there is no primitive for the MTP3-User to request this audit from the M3UA layer, as this is initiated by an internal M3UA management function. """ This is not enabled by default since it's optional according to specs, and some SGs may actually return errors (it's possible according to RFC4666 to deny access to auditing by the SG).
