[M] Change in ...pyosmocom[master]: tlv: preserve the comprehension bit
by Hoernchen 06 Aug '26

06 Aug '26

Hoernchen has uploaded this change for review. ( https://gerrit.osmocom.org/c/python/pyosmocom/+/43171?usp=email ) Change subject: tlv: preserve the comprehension bit ...................................................................... tlv: preserve the comprehension bit The comprehension bit is data, not part of the tag: TS 101 220 7.1.1 defines it as an instruction to the receiver for treating IEs it does not understand, which is why is_tag_compatible() masks it when matching -> _encode_tag() re-emits the class tag, but ComprTlvMeta forces CR, so decode(x)/encode() did not round trip properly for IEs without the bit set That is not hypothetical! GP Amendment B administration session parameters stored by UICCs in an EF carry the CAT TLVs inside tag 0x84 with the bit mixed: - set on Command details and Device identities - clear on the optional ones That means reading and writing the same data led to not writing the same data at all! The cleanest fix here is to tri-state COMPR_TLV_IE.comprehension: - None for an IE built from scratch which encode as before - True/False for one parsed from a file which will now properly roundtrip. _encode_tag() properly passes the flag to comprehensiontlv_encode_tag() explicitly instead of deriving it from the int: The int can't express "CR clear" for a one-byte tag at all, and silently drops the flag for a two-byte one.... While at it fix ComprTlvMeta which would destroy two-byte tags instead of setting the flag, currently tag=0x8123 -> 0x81a3.

laforge has submitted this change. ( https://gerrit.osmocom.org/c/simtrace2/+/43124?usp=email ) Change subject: firmware: iso7816_3: fix F/D ratio for Di 8 and 9 ...................................................................... firmware: iso7816_3: fix F/D ratio for Di 8 and 9 iso7816_3_compute_fd_ratio() multiplied F by D for every d_index >= 8, presumably because the upper half of ISO 7816-3 Table 8 encodes 1/D. But 7816-3 2006 and 1997 differ! That assumption is only true for the range 1010..1111, which in the 2006 version is RFU. Indices 1000 and 1001 are Di = 12 and Di = 20, see iso7816_3_di_table[]. So right now Fi=372/Di=12 -> 372 * 12 = 4464 instead of 372 / 12 = 31. In the cemu value is rejected in emu_update_fidi() and the old baud rate is silently kept. In the sniffer update_fidi() programs US_FIDI as 4464 & 0x7ff = 368, which is garbage. Use F/D for indices 1..9 and keep the legacy 1/D reading only for the RFU range, where we cant really do anything useful anyway.
