Change subject: pcu_sock: fix endian-swapped CellID
Patch Set 1: Code-Review-1
PS1, Line 14: to OsmoBTS, then with a socket to OsmoPCU. OsmoBTS was always sending
"the CellID is configured in OsmoBSC, sent via RSL to OsmoBTS" -> as BE.
"OsmoBTS was always sending the swapped CellID to OsmoPCU" -> meaning it's sending a BE integer over a unix socket in a LE system(wrong!)? Or swapping the value before sending it over the unix socket (correct)?
"In March 2018, a regression in OsmoPCU () caused it to swap the CellID again" -> What do you mean with "spaw" here? moved in code? because I see it moves the line but still uses ntohs().
"This regression was fixed in March 2019 ()." -> Ok, here cellID coming from unix socket is handled as LE on a LE system, fine.
Please rework the commit description so it's clear what you mean.
PS1, Line 262: bts->cell_identity = ntohs(si3->cell_identity);
So here we are again handling a BE integer coming from a unix socket (intra-host)? Why? I'd expect to receive a host endianess integer here.
