lynxis lazus gerrit-no-reply at lists.osmocom.orglynxis lazus has uploaded this change for review. ( https://gerrit.osmocom.org/c/libosmocore/+/21574 ) Change subject: gprs_ns2_sns: use different binds for the initial connection ...................................................................... gprs_ns2_sns: use different binds for the initial connection In case the first bind is not working the SNS would never build a succesful connection to the SGSN. Iterate over all binds by using an offset. Instead of tracking the binds use an offset instead of a direct pointer. This might result in skipping the order of the next bind.
