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 of problem:

kvm_vm_ioctl_assign_irq() checks for CAP_SYS_RAWIO, which is not present for qemu processes launched via libvirt.  This check really isn't necessary since it can only operate on devices previously assigned via the assign_device ioctl.  Remove the check.

Version-Release number of selected component (if applicable):
2.6.32-28.el6

How reproducible:
always

Steps to Reproduce:
1. assign passthrough device via libvirt
2. fail (note this isn't the only problem blocking this path)
3.
  
Actual results:
assign_irq ioctl fails

Expected results:
works

Additional info:

Created attachment 416999 [details]
upstream patch backported to rhel6

Here's the patch posted to rhkernel-list.  This was accepted upstream.  assign_irq only works on devices already registered through assign_device, so it doesn't make much sense to enforce RAWIO here.

Patch(es) available on kernel-2.6.32-31.el6

Tested on  kernel-2.6.32-63.el6
PASS
