This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed- bionic'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

This commit Fixes: 121f80ba68f1. Commit 76fa4975f3ed also requires mainline commit 1463edca6734 as a prereq. Both these commits have already been cc'd to upstream stable, but they have not landed in Bionic as of yet. == Fixes == 1463edca6734 ("vfio/spapr: Use IOMMU pageshift rather than pagesize") 76fa4975f3ed ("KVM: PPC: Check if IOMMU page is contained in the pinned physical page") == Regression Potential == Low. These commits have also been sent to upstream stable, so have had additional upstream review. == Test Case == A test kernel was built with these patches and tested by the original bug reporter. The bug reporter states the test kernel resolved the bug. == Comment: #0 - Leonardo Augusto Guimaraes Garcia - 2018-08-06 12:27:59 == Please, add the following security fix to the distro kernel: 76fa4975f3ed KVM: PPC: Check if IOMMU page is contained in the pinned physical page Also already available in the 4.14 stable tree: 58113603a4ea KVM: PPC: Check if IOMMU page is contained in the pinned physical page And in the 4.17 stable tree: 970e28cb2c7a KVM: PPC: Check if IOMMU page is contained in the pinned physical page To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1785675/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
