[M] Change in libosmo-sigtran[master]: ASP loadsharing: Pass ownership of Tx xua_msg down the stack [1/2]

by pespin

pespin has submitted this change. ( https://gerrit.osmocom.org/c/libosmo-sigtran/+/39396?usp=email ) ( 10 is the latest approved patch-set. No files were changed between the latest approved patch-set and the submitted one. )Change subject: ASP loadsharing: Pass ownership of Tx xua_msg down the stack [1/2] ...................................................................... ASP loadsharing: Pass ownership of Tx xua_msg down the stack [1/2] This is a first step towards getting MTP OPC & SLS fields down the stack so that they can be used to implement loadsharing at ASP level. So far, we always encode the xua_msg (which holds the OPC and SLS info into xua_msg->mtp) into a msgb before passing it to as->fi through event XUA_AS_E_TRANSFER_REQ, which in turn calls xua_as_transmit_msg(as, msg). This patch is part 1 of 2 patches, which only modifies mostly the Tx path, but still requires modifications on Rx path (done in patch 2/2) to properly handle the forwarding path from Rx to Tx without double freeing. It is submitted in 2 parts to ease code reviewing. Future patches will modify that code to pass a xua_msg and only encode it into a msgb deeper into the stack after an ASP has been selected and msg needs to be transmitted. All previous calls to sua_tx_xua_asp() actually had a memory leak before this change, hence why no xua_msg_free() is removed from callers in this patch. Since now ownership is taken by sua_tx_xua_asp() which always frees the xua msg, the memleak is fixed.
