[S] Change in osmo-tetra[master]: Added support for slot stealing

by wbokslag

wbokslag has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-tetra/+/33942 ) Change subject: Added support for slot stealing ...................................................................... Added support for slot stealing Slot stealing is how a traffic slot can be partially or fully "stolen" by a control channel. This patch adds support for that and maintains the stealing status in the tetra_mac_state. This can be used to prevent passing a signalling half slot to the voice decoder.

[M] Change in pysim[master]: construct: add adapter Utf8Adapter to safely interpret utf8 text

by dexter

dexter has uploaded this change for review. ( https://gerrit.osmocom.org/c/pysim/+/33941 ) Change subject: construct: add adapter Utf8Adapter to safely interpret utf8 text ...................................................................... construct: add adapter Utf8Adapter to safely interpret utf8 text Uninitialized Files, File records or fields in a File record or File usually contain a string of 0xff bytes. This becomes a problem when the content is normally encoded/decoded as utf8 since by the construct parser. The parser will throw an expection when it tries to decode the 0xff string as utf8. This is especially a serious problem in pySim-trace where an execption stops the parser. Let's fix this by interpreting a string of 0xff as an empty string.
