* gsm_04_08.h: add R99 MSCR and CBQ3 to SI3 Ctrl Chan DescrNeels Hofmeyr2017-02-231-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | MSCR and CBQ3 are Release 1999 additions to the Control Channel Description IE of SI3. Assuming that no-one is using the spare bits, this will not cause any code conflicts. In the R99 struct, spare1 and spare2 are in different places, so rather rename them to spare_1 and spare_2 to make sure we get a compiler barf *if* anyone tries to use them with the wrong structure. Adjust the spec reference to TS 44.018; TS 04.08 Figure 10.5.33 is replaced by TS 44.018 Figure 10.5.2.11.1 which is right there in the named Section 10.5.2.11, so drop the explicit reference. Motivation: the R99 Control Channel Description defines MSCR to indicate whether the MSC is R99+ or not. To use UMTS AKA on GSM networks, we want to indicate that our libmsc is capable of R99, like OsmoSGSN already does. CBQ3 is merely added for completeness, no particular use case in mind.

* GSUP, OAP, osmo-gen-vec: fix AUTS length to 14, not 16Neels Hofmeyr2017-02-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | GSUP transmits AUTS for UMTS authentication procedures, and OAP uses the same procedures to authenticate. osmo-gen-vec is a utility program that passes AUTS to our osmo_auth_gen_vec_auts() API. According to 3GPP 33.102 6.3.3, AUTS = SQN^AK || MAC-S, which are 6 || 8 == 14 bytes. This is confirmed by 24.008 9.2.3a where the TLV has 16 bytes, TL = 2 and AUTS being the V = 14. It is not harmful for milenage_gen_vec_auts() to pass two more AUTS bytes. But writing 16 bytes to a GSUP struct is a potential problem when passing in a 14 byte long AUTS buffer to the GSUP API, which then reads past the AUTS buffer. The API implies the length, so far to be 16, so passing in a 14 byte buffer to GSUP would require copying to a larger buffer first. Fix this by using a length of 14 for AUTS everywhere instead. This constitues an ABI breakage, we may handle it as a "fix before an official release", otherwise we need a version bump. The OAP protocol document has also been updated, needs an update in the osmo-gsm-manuals as well. Change-Id: If25b173d9ec57ea4c504d860954912b7d82af455
