[M] Change in osmo-bts[master]: Use polling based LAPDm with frame numbers

by jolly

Attention is currently required from: fixeria, jolly, laforge. Hello Jenkins Builder, fixeria, laforge, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-bts/+/35007?usp=email to look at the new patch set (#7). The following approvals got outdated and were removed: Code-Review+2 by fixeria, Code-Review-1 by laforge, Verified+1 by Jenkins Builder The change is no longer submittable: Code-Review and Verified are unsatisfied now. Change subject: Use polling based LAPDm with frame numbers ...................................................................... Use polling based LAPDm with frame numbers Osmo-bts uses the new polling based LAPDm implementation. The OML message NM_ATT_T200 is ignored, because T200 timeouts are set to the minimal response time. Longer timeouts would cause lower throughput in case of lost frames. Shorter timeouts would cause LAPDm to fail.

[M] Change in libosmocore[master]: osmo_io: Remove union in struct osmo_io_ops

by pespin

Attention is currently required from: arehbein, daniel, laforge. pespin has posted comments on this change. ( https://gerrit.osmocom.org/c/libosmocore/+/35079?usp=email ) Change subject: osmo_io: Remove union in struct osmo_io_ops ...................................................................... Patch Set 4: (1 comment) Patchset: PS4: I'd actually keep the union, imho there's nothing wrong with it if used, plus: - Doesn't break ABI with previous libosmocore release - It saves some bytes on each osmo_io (there can be a big number of them in an app). I agree though that the comment you mentioned should be fixed by checking the correct io_mode is in used before checking the pointer, since it's shared with other io_modes through the union. TL;DR: Fix the code bugs, leave the union. If still others prefer merging this, I won't oppose, just saying. -- To view, visit https://gerrit.osmocom.org/c/libosmocore/+/35079?usp=email To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: libosmocore Gerrit-Branch: master Gerrit-Change-Id: I138d57843edc29000530bb7896bcb239002ecbec Gerrit-Change-Number: 35079 Gerrit-PatchSet: 4 Gerrit-Owner: daniel <dwillmann(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: arehbein <arehbein(a)sysmocom.de> Gerrit-Reviewer: laforge <laforge(a)osmocom.org> Gerrit-CC: pespin <pespin(a)sysmocom.de> Gerrit-Attention: arehbein <arehbein(a)sysmocom.de> Gerrit-Attention: laforge <laforge(a)osmocom.org> Gerrit-Attention: daniel <dwillmann(a)sysmocom.de> Gerrit-Comment-Date: Wed, 29 Nov 2023 18:31:40 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Gerrit-MessageType: comment

[M] Change in osmo-hnbgw[master]: mgw_fsm: Modify RAB on HNB if IuUP local IP addr at MGW changes durin...

by pespin

pespin has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-hnbgw/+/35168?usp=email ) Change subject: mgw_fsm: Modify RAB on HNB if IuUP local IP addr at MGW changes during MDCX ...................................................................... mgw_fsm: Modify RAB on HNB if IuUP local IP addr at MGW changes during MDCX Allow IP address renegotation between HNB and MGW: * Upon MGCP MDCX ACK received from the RAN-side conn, if the IP address/port changes, then restart the RAB-Ass-Req+Resp procedure on Iuh. * Upon RAB-Ass-Resp received from the HNB, if the IP address/port changes, then go through another MDCX + MDCX ACK prcoedure on MGCP. An MDCX counter is introduced to avoid infinite loops where the HNB and the MGW keep changing their IP address triggered by the change on the other side, eg. due to incorrect network/routing setup. The counter is also used to track count in order to make sure that always at least 1 MDCX is transmitted, in order to change conn_mode to SEND_RECV.

[M] Change in libosmocore[master]: osmo_io: Remove union in struct osmo_io_ops

Attention is currently required from: arehbein. Hello Jenkins Builder, arehbein, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/libosmocore/+/35079?usp=email to look at the new patch set (#4).
