Patch Set 1: (1 comment) Patchset: PS1: > Ah indeed, 4 bytes is only possible for an APDU but not a TPDU. See ETSI TS > 102 221 Section 7.3.1.1. […] Yes, that is correct. I would assume that CCID sees only TPDUs, so if there is something below 5 bytes, it should be indeed rejected. -- To view, visit https://gerrit.osmocom.org/c/osmo-ccid-firmware/+/42192?usp=email To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings?usp=email Gerrit-MessageType: comment Gerrit-Project: osmo-ccid-firmware Gerrit-Branch: master Gerrit-Change-Id: I65df88477e4b1c03dc20a8d41e5cbd1c9f363ba8 Gerrit-Change-Number: 42192 Gerrit-PatchSet: 1 Gerrit-Owner: laforge <[email protected]> Gerrit-Reviewer: Hoernchen <[email protected]> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: jolly <[email protected]> Gerrit-Reviewer: lynxis lazus <[email protected]> Gerrit-CC: dexter <[email protected]> Gerrit-Attention: Hoernchen <[email protected]> Gerrit-Attention: jolly <[email protected]> Gerrit-Attention: laforge <[email protected]> Gerrit-Attention: lynxis lazus <[email protected]> Gerrit-Comment-Date: Wed, 25 Feb 2026 16:37:53 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: laforge <[email protected]> Comment-In-Reply-To: lynxis lazus <[email protected]>
