[S] Change in osmo-bts[master]: CSD RTP: verify alignment of V.110 frames

Attention is currently required from: falconia. Hello Jenkins Builder, fixeria, pespin, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-bts/+/38555?usp=email to look at the new patch set (#4). The following approvals got outdated and were removed: Verified+1 by Jenkins Builder The change is no longer submittable: Verified is unsatisfied now. Change subject: CSD RTP: verify alignment of V.110 frames ...................................................................... CSD RTP: verify alignment of V.110 frames Since the beginning of CSD implementation, OsmoBTS has operated with an implicit (unstated) policy that V.110 frames must be perfectly aligned within received clearmode RTP packets - a requirement which is NOT set anywhere in TS 48.103 or any of the other specs it references. This design policy is sensible from the standpoint of implementation complexity (both OsmoBTS and osmo_trau2rtp emit such perfectly aligned packets; if someone is building a gateway between an Osmocom GSM network and ISDN-style external networks, that gateway can act as the aligner), but it should be explicit rather than implicit. Check V.110 frame alignment in received clearmode RTP packets, and reject packets that fail this alignment check.

[S] Change in osmo-bts[master]: csd_v110: set E2 bit correctly for TCH/[FH]4.8 NT
by falconia 28 Oct '24

Attention is currently required from: falconia, pespin. Hello Jenkins Builder, fixeria, pespin, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-bts/+/38554?usp=email to look at the new patch set (#4). The following approvals got outdated and were removed: Verified+1 by Jenkins Builder The change is no longer submittable: Verified is unsatisfied now. Change subject: csd_v110: set E2 bit correctly for TCH/[FH]4.8 NT ...................................................................... csd_v110: set E2 bit correctly for TCH/[FH]4.8 NT In all classic NT modes below 14.5 kbit/s, V.110 frame bits E2 and E3 are repurposed to indicate the alignment whereby a single 240-bit RLP frame is composed of 4 pseudo-V.110 frames in switching transport. (TS 48.020 section 15.1.) In the case of TCH/F9.6, setting both E2 and E3 is easy because all 4 pseudo-V.110 frames go out in the same clearmode RTP packet as a result of a single channel decoding operation. However, in the case of TCH/F4.8 there are two separate channel decoding operations producing two separate RTP packets 20 ms apart. Furthermore, GSM 05.03 section 3.4.1 specifies which TDMA frame positions hold which half of the RLP frame - therefore, the correct emission of bit E2 needs to be based on the TDMA frame number at which the block was received. A similar situation occurs with TCH/H4.8 NT: we receive a single block from the 05.03 decoder every 40 ms, containing a full RLP frame, but we emit it as two separate RTP packets, each carrying 20 ms worth of bits. These RTP packets also require correct setting of E2 bit.
