gbproxy: Avoid sending STATUS on unexpected BLOCK_ACK Handle SGSN BVCs that are gone from the BSS differently. The previous patch removed the gbproxy_bvc on the SGSN-side after it was gone on the BSS-side. This caused a STATUS response to BVC_BLOCK_ACK messages that should be valid. Instead of removing the BVC this patch marks it as inactive so we can still handle BVC_BLOCK_ACK correctly, but ignore other messages - especially BVC_RESET from the SGSN. Related: SYS#5628. OS#5236 Change-Id: Ic9f34a27412d6e15ca1198ee140f66a076b5c6b6
osmo-gbproxy is a proxy for the Gb interface within the 3GPP GERAN (GPRS/EDGE RAN) architecture. It is part of the Osmocom Open Source Mobile Communications projects.
It allows you to aggregate many Gb links/connections into one. It also has the ability to convert between different Gb interface protocol stacking, such as from Gb-over-FrameRelay to Gb-over-IP.
Until 2021 it used to be part of the osmo-sgsn git repository, and before that (until 2017) part of openbsc.git
