Description Jakub Jelen 2018-06-08 13:42:41 UTC
Description of problem:
During the implementation of CAC2 in libcacard, we identified issue with handling of packet of specific sizes in qemu.

The change [1] is already reviewed and merged upstream and to my understanding, it is not yet merged in the RHEL. This is needed for the ongoing work to support smart card sharing (described in the bug #917867).

Version-Release number of selected component (if applicable):

How reproducible:
deterministic for message of multiplies of 64 B

Steps to Reproduce:
1. Request 32 B data from the smart card emulator, which will add to 64 B on USB packet layer.

Actual results:
USB in guest times out while waiting for the answer from host

Expected results:
USB packet should be delivered

Comment 15 Miroslav Rezanina 2018-08-29 03:06:22 UTC
Fix included in qemu-kvm-rhev-2.12.0-12.el7

Comment 26 Jakub Jelen 2018-09-11 08:44:11 UTC
A1: As already pointed out in comment #24 we should be able to verify this bug without the fix for the bug bug #917867.

A2: I don't have RHEL7 testing machine so I am using Fedora versions:

libcacard-2.5.3-4.fc28.x86_64 --- this is quite the same as in RHEL7

Updating qemu to the latest testing version in Fedora

qemu-kvm-2.11.2-4.fc28.x86_64 -- this has basically only the fix for this bug on top of the previous version

makes also the second command from comment #24 working for me. What output you get from the commands in the comment #24?
