1524845 – wodim --devices and other commands fail because of wrong kernel release check in libusal

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.

Description Renaud Métrich 2017-12-12 08:56:40 UTC

Description of problem:

On RHEL7, trying to scan devices using "wodim --devices" or "wodim -scanbus" fails with following error:

wodim: No such file or directory. 
Cannot open SCSI driver!
For possible targets try 'wodim --devices' or 'wodim -scanbus'.
For possible transport specifiers try 'wodim dev=help'.
For IDE/ATAPI devices configuration, see the file README.ATAPI.setup from
the wodim documentation.

Using strace, we can see that /dev/sg* devices are not scanned.
This is due to a broken test against kernel 2.6 done in libusal, causing kernel "3.10" to be recognized as a "2.x" kernel (x >= 6).


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

wodim-1.1.11-23.el7_4


How reproducible:

Always


Steps to Reproduce:
1. run wodim --devices

Actual results:

wodim: No such file or directory. 
Cannot open SCSI driver!
For possible targets try 'wodim --devices' or 'wodim -scanbus'.
For possible transport specifiers try 'wodim dev=help'.
For IDE/ATAPI devices configuration, see the file README.ATAPI.setup from
the wodim documentation.


Expected results:

wodim: Overview of accessible drives (2 found) :
-------------------------------------------------------------------------
 0  dev='/dev/sg0'	rwrw-- : 'QEMU' 'QEMU DVD-ROM'
 1  dev='/dev/sg1'	rwrw-- : 'QEMU' 'QEMU CD-ROM'
