Description Alon Levy 2011-07-21 09:37:46 EDT
Created attachment 514204 [details]
fix for this bug.

Description of problem:
Using a spice smartcard connection with AET middleware doesn't work correctly due to the middleware reporting it supports CKM_RSA_X_509 when it doesn't.

fix is attached. sent to qemu upstream. (qemu mailing list is used for libcacard related fixes since libcacard is part of qemu code repository.)

Version-Release number of selected component (if applicable):
libcacard-0.1.2-2.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1. start qemu with emulated smartcard (['-chardev', 'spicevmc,id=smartcard,debug=3,name=smartcard', '-device', 'usb-ccid,debug=1,id=ccid', '-device', 'ccid-card-passthru,debug=1,chardev=smartcard'])
2. start spicec with --enable-smartcard
3. smartcard appears in vm, but cannot complete a pk11_listcerts

Actual results:
errors

Expected results:
requests pin and shows certs.

Comment 1 Alon Levy 2011-07-21 09:40:15 EDT
Adding Rebase keyword. Since the previous version of libcacard (0.1.2-2) the sources have moved from an independent repository to be part of the qemu repository. This was not just a copy operation, but included fixes for reusing qemu infrastructure and applying qemu coding style, and a number of bug fixes have also been done on that code base. As a result a rebase of libcacard is recommended. It will include a fix for this bug.
