Harald Welte gerrit-no-reply at lists.osmocom.orgHarald Welte has submitted this change and it was merged. ( https://gerrit.osmocom.org/10218 ) Change subject: remsim: fix payload overwriting ...................................................................... remsim: fix payload overwriting The slot number is in the header, and correctly set in st_push_hdr. Setting the slot in st_slot_tx_msg will overwrite the payload data. This caused bytes three of the ATR to be changed from 0x96 to 0x00, corrupting the ATR. This corruption is caught by the ATR checksum, and the modem would reset the card (2 additional times) to try to get correct ATR.
