[M] Change in simtrace2[master]: Add osmo_apdu_segment_in2() to ensure correct parsing of GP GET DATA
by dexter 12 Aug '26

Attention is currently required from: laforge, lynxis lazus. dexter has posted comments on this change by lynxis lazus. ( https://gerrit.osmocom.org/c/simtrace2/+/43185?usp=email ) Change subject: Add osmo_apdu_segment_in2() to ensure correct parsing of GP GET DATA ...................................................................... Patch Set 3: Code-Review+1 (10 comments) Patchset: PS3: I have looked through your patch. Unfortunately I do not have the big picture, but the problem you describe and the solution appears to make sense. As far as I understand the problem is that the information about the original APDU case gets lost and this later causes problems when forwarding it. That is why you transfer the prev_ac->apdu_case to ac->apdu_case. Where I am a bit lost is to understand the difference between ETSI TS 102 221, Table 7.1 and GlobalPlatform A.1. They both apparently perform the re-send in the same manner. Maybe this corner case is more generic than originally assumed. You may also have a look [1], maybe this is helpful.

I am having difficulties to understand this description. After responding we cannot go back and manipulated the Le field, we would have to go back in time. Which we cannot. Do you mean prev_ac with that. Or do you wanted to write ".. the following GP GET DATA ..."? File host/lib/apdu_dispatch.c: https://gerrit.osmocom.org/c/simtrace2/+/43185/comment/177859c7_811fa7c0?us… : PS3, Line 86: * \param prev_ac Previous APDU context across successive calls ac and prev_ac are [inout], right? (its probably not necessary to explicitly mark inout parameter in doxygen...) https://gerrit.osmocom.org/c/simtrace2/+/43185/comment/00bf6a02_a1d0661d?us… : PS3, Line 120: ac->hdr.cla & 0x80 && /* check for GP */ In GlobalPlatform Card Specification, section 11.3.2 they list more possible CLA bytes.

Maybe it is better to pass true instead of 1 then. Its the same, but easier to read. https://gerrit.osmocom.org/c/simtrace2/+/43185/comment/30c364ec_cb77aaaf?us… : PS3, Line 70: OSMO_ASSERT(rc == APDU_ACT_TX_CAPDU_TO_CARD); I wonder if it would make sense to inspect the contents of ac and prev_ac after osmo_apdu_segment_in2 was called. -- To view, visit https://gerrit.osmocom.org/c/simtrace2/+/43185?usp=email To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings?usp=email Gerrit-MessageType: comment Gerrit-Project: simtrace2 Gerrit-Branch: master Gerrit-Change-Id: Ie238662e7e6a10dd4283ede0c8d8d73bc375c247 Gerrit-Change-Number: 43185 Gerrit-PatchSet: 3 Gerrit-Owner: lynxis lazus <lynxis(a)fe80.eu> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: dexter <pmaier(a)sysmocom.de> Gerrit-Reviewer: laforge <laforge(a)osmocom.org> Gerrit-Attention: laforge <laforge(a)osmocom.org> Gerrit-Attention: lynxis lazus <lynxis(a)fe80.eu> Gerrit-Comment-Date: Wed, 12 Aug 2026 11:03:55 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: Yes

laforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-ci/+/43206?usp=email ) Change subject: ansible: obsworker: restart on failure ...................................................................... ansible: obsworker: restart on failure The obsworker service can fail if it can't reach the OBS server after it started. Let it retry continuously until the server comes up again. As the original service is of type "oneshot", Restart=on-failure must be used instead of Restart=always (https://unix.stackexchange.com/a/777329).
