Hello Jenkins Builder,

to look at the new patch set (#2).
Change subject: improve handling of BSC-chosen algo in CIPHER MODE COMPLETE
......................................................................
improve handling of BSC-chosen algo in CIPHER MODE COMPLETE
The BSC may choose to omit the chosenEntryptionAlgorithm IE in
the CIPHER MODE COMPLETE command. When this happens, we used to
default to A5/1 and disregarded the list of ciphers which we
requested in the CIPHER MODE CMD. Fall back to the best cipher
instead of hard-coding a fallback to A5/1.
If the BSC does specify an algorithm, ensure that the chosen value
falls within the range allowed by GSM 04.08, and ensure that the
chosen value matches one of the values we sent in CIPHER MODE CMD.
