RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
.Improved padding for `pkcs11`
Previously, the `pkcs11` token label had extra padding for some smart cards. As a consequence, the wrong padding could cause issues matching cards based on the label attribute. With this update, the padding is fixed for all the cards and defined PKCS #11 URIs and matching against them in application should work as expected.
Description of problem:
In opensc-0.20.0, I am seeing additional padding in the PKCS #11 token label for some smart cards.
Using the following command I got information on a few different cards I have:
[root@rhel8-8 ~]# PKCS11SPY=/usr/lib64/pkcs11/opensc-pkcs11.so p11tool --provider /usr/lib64/pkcs11-spy.so --list-all-certs 2>&1 | grep -A5 C_GetTokenInfo
####################################
Aventra MyEID:
####################################
4: C_GetTokenInfo
...
label: ' MyEID (sctest)'
manufacturerID: 'Aventra Ltd. '
####################################
SCP03 card enrolled from RHCS earlier:
####################################
4: C_GetTokenInfo
...
label: ' kdcuser2 (kdcuser2)'
manufacturerID: '534e SafeNet '
####################################
CAC/PIV card from US DoD:
####################################
4: C_GetTokenInfo
...
label: 'FLUORINE.JANE.F.2001441054 '
manufacturerID: 'piv_II '
####################################
Another CAC from US DoD:
####################################
4: C_GetTokenInfo
..
label: 'CONTRACTOR.DUALCAC.1402516816 '
manufacturerID: 'piv_II '
Version-Release number of selected component (if applicable):
opensc-0.20.0-2.el8.x86_64
How reproducible:
Always
Steps to Reproduce:
1. dnf install opensc
2. systemctl start pcscd
3. p11tool --provider /usr/lib64/opensc-pkcs11.so --list-all-certs
4. PKCS11SPY=/usr/lib64/pkcs11/opensc-pkcs11.so p11tool --provider /usr/lib64/pkcs11-spy.so --list-all-certs 2>&1 | grep -A5 C_GetTokenInfo
Actual results:
4. extra %00 padding seen in p11tool output
5. spaces to left not right of the label.
Expected results:
4. no extra padding
5. spaces to the right not left of the label
Additional info:
This is fixed by the following upstream pull request:
https://github.com/OpenSC/OpenSC/issues/1922
This does not affect all cards, but just the ones that have specific PIN name and token label.
I added known-issue doc text to get it to release notes, as it is probably late to fix it in rhel8.3.
