Move sccp_address_book logic out of vty.c Move it tto a file containing data domain code. Move the struct definition to a header so it can be used in other files like ss7_vty.c. It will be used in more places in follow-up patches.

[M] Change in libosmo-sigtran[master]: xua_snm.c: Handle DAUD with aff_pc containing wildcards

by pespin

Attention is currently required from: daniel, laforge. Hello Jenkins Builder, daniel, laforge, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/libosmo-sigtran/+/40498?usp=email to look at the new patch set (#3). The following approvals got outdated and were removed: Verified+1 by Jenkins Builder Change subject: xua_snm.c: Handle DAUD with aff_pc containing wildcards ...................................................................... xua_snm.c: Handle DAUD with aff_pc containing wildcards Handle it with a really basic implementation for completeness. In theory we shouldn't in general be receiving such big masks, since RFC466 3.4.3 states: """ It is recommended that during normal operation (traffic handling) the mask field of the Affected Point Code parameter in the DAUD message be kept to a zero value in order to avoid SG overloading.
