[M] Change in osmo-hnbgw[master]: [RFC] drop list of HNBAP UE Context

by neels

Attention is currently required from: laforge. neels has posted comments on this change. ( https://gerrit.osmocom.org/c/osmo-hnbgw/+/32041 ) Change subject: [RFC] drop list of HNBAP UE Context ...................................................................... Patch Set 2: (1 comment) Patchset: PS2: > I think this could have implications when we start to support things like SABP (Service Area Broadca […] The point being, we don't use ue_context for active Iu connections. This is some completely optional HNBAP, it has no effect on any RUA conns at all. Actually I recently noticed, our ttcn3-hnbgw tests omit the HNBAP UE Register completely, they only do HNBAP HNB Register On HNBAP UE Register, we store the allocated context id in a linked list. On HNBAP UE De-Register, we always ACK that, and also drop the id from the list without caring whether it exists. That is literally all that osmo-hnbgw does with the HNBAP UE Context. So I guess we can apply this patch to completely drop ue_context in case that the ue_context leak situation continues to steal our time. Let's wait how the just merged patches turn out. -- To view, visit https://gerrit.osmocom.org/c/osmo-hnbgw/+/32041 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-hnbgw Gerrit-Branch: master Gerrit-Change-Id: Ida7eadf36abcf465ae40003725c49e8e321a28c9 Gerrit-Change-Number: 32041 Gerrit-PatchSet: 2 Gerrit-Owner: neels <nhofmeyr(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-CC: laforge <laforge(a)osmocom.org> Gerrit-Attention: laforge <laforge(a)osmocom.org> Gerrit-Comment-Date: Tue, 28 Mar 2023 02:14:47 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: laforge <laforge(a)osmocom.org> Gerrit-MessageType: comment

[S] Change in osmo-hnbgw[master]: release UE Contexts on SCTP_RESTART

by neels

neels has submitted this change.

(The HNB typically connects via HNBAP shortly after this causing a UE Context clearing too, but UE state should always be cleared on SCTP_RESTART, no matter what.)

[S] Change in osmo-hnbgw[master]: release UE Contexts on HNB (Re-)Register

by neels

neels has submitted this change. ( https://gerrit.osmocom.org/c/osmo-hnbgw/+/32037 ) Change subject: release UE Contexts on HNB (Re-)Register ...................................................................... release UE Contexts on HNB (Re-)Register Whenever a HNB reconnects, we want to discard all previous UE state and any active connections. In one HNB reconnect scenario, we receive SCTP_RESTART. This sets hnb_registered == false, which in turn skipped the UE cleanup step in hnbgw_rx_hnb_register_req(), leaking UE Contexts. Remove all weird conditions like that, and simply clear out all UE state whenever a HNB registers, period.
