[S] Change in osmo-bts[osmith/1.7.1]: l1sap: l1sap_tch_ind(): fix segfault on stale TCH.ind

by osmith

osmith has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-bts/+/34680?usp=email ) Change subject: l1sap: l1sap_tch_ind(): fix segfault on stale TCH.ind ...................................................................... l1sap: l1sap_tch_ind(): fix segfault on stale TCH.ind It was reported that osmo-bts-sysmo is crashing due to a TCH.ind primitive being received by l1sap_tch_ind() for an lchan, which is operating neither in speech nor data, but in signalling mode. It's not clear which scenario is causing this situation. My best guess is that one or more TCH.ind primitive(s) remain waiting in the lower layers and bob up right after the channel mode change. This can happen, for instance, when a dynamic timeslot gets switched from TCH/F or TCH/H to PDCH or SDCCH/8.

[S] Change in osmo-bts[osmith/1.7.1]: ASCI: Ignore LAPD frames from MS, while the uplink is not active
