Hello pespin, fixeria, neels, Jenkins Builder,
I'd like you to reexamine a change. Please visit
to look at the new patch set (#2).
Change subject: pcu_sock: fix endian-swapped CellID
pcu_sock: fix endian-swapped CellID
Convert the cell identity to LE when sending it to the PCU via unix
socket, just like we do it with the location area code.
In the Osmocom stack, the CellID is configured in OsmoBSC, sent as BE
via RSL to OsmoBTS, then with a socket to OsmoPCU (where OsmoPCU expects
it to be LE in a LE system). OsmoBTS was always sending the CellID as
BE to OsmoPCU. In March 2018, a regression in OsmoPCU  caused an
endianness swap in the CellID on LE systems, resulting by chance in the
correct, LE encoded, CellID as it should have been sent from OsmoBSC
(for LE systems). This regression was fixed in March 2019 .
I've verified this fix with a TTCN3 test .
