        New security update candidates (xen, microcode_ctl)

        A new XSA was published on August 14th 2024.
        Intel published an updated microcode on August 13th 2024.

        • XSA-460 passing through some PCI devices after guest creation could lead to any kind of security issue (DoS, privilege escalation, information leak,…) the actual risk depends on the systems and the devices passed through.
        • XSA-461 some pass-through use cases when on one or more device when they share resources are actually not possible to be made secure. This XSA updates the Xen documentation to reflect that.

        SECURITY UPDATES

        • xen-*:
          • Fix XSA-460 - error handling in x86 IOMMU identity mapping. The handling of errors in the case of mapping Reserved Memory Regions was flawed, potentially keeping the mapping in place, this could allow guests to access memory region they should not be allowed to access. These mapping are typically used when doing pass-through of legacy USB emulation.
          • Document XSA-461 - PCI device pass-through with shared resources Files. According to the Xen Project security team, PCI pass-through of devices that share ressources is not possible to be made safe. This updates the documentation to reflect it. Look at the "MITIGATION" section of the XSA for more information regarding the safe cases.
        • microcode_ctl: Security updates from Intel:
          • INTEL-SA-01083
          • INTEL-SA-01118
          • INTEL-SA-01100
          • INTEL-SA-01038
          • INTEL-SA-01046
          • Plus fixes for a lot of functional issues, see the Release Notes for more details.

        Test on XCP-ng 8.2

        yum clean metadata --enablerepo=xcp-ng-candidates
yum update "xen-*" microcode_ctl --enablerepo=xcp-ng-candidates
reboot

        The usual update rules apply: pool coordinator first, etc.

        Versions:

        • xen: 4.13.5-9.40.3.xcpng8.2
        • microcode_ctl: 2.1-26.xs29.3.xcpng8.2

        What to test

        Normal use and anything else you want to test. Feedback about PCI pass-through is also welcome.

        Test window before official release of the update

        ~ 2 day because of security updates.

                I just pushed an update for microcode_ctl, in xcp-ng-candidates again.

                It only changes one microcode file, 06-a5-03 (CML-S62, Core Gen 10), which Intel had forgotten to update in their initial release.

                (We found out and reported it to them)

                      New security update candidates (xen, microcode_ctl)

                      A new XSA was published on September 24th 2024.
                      Intel published a microcode update on the September 10th 2024.
                      We also included an updated xcp-ng-release for testing, althrough not related to security.

                      • XSA-462 a malicious HVM or PVH guest can trigger a DoS of the host.

                      SECURITY UPDATES

                      • xen-*:
                            * Fix XSA-462 - x86: Deadlock in vlapic_error(). The handling of x86's APIC (Advanced Programmable Interrupt Controller) allows a guest to configure an illegal vector to handle error interrupts. This causes the vlapic_error() to recurse, this is protected, but the lock used for this protection will try to be taken recursiveley, leading to a deadlock.
                      • microcode_ctl:
                            * Latest Intel microcode update, still named IPU 2024.3, including security updates for:
                                * INTEL-SA-01103
                                * INTEL-SA-01097

                      Other updates

                      • xcp-ng-release:
                            * Update the "XOA Quick deploy" feature in the host's web page.
                            *  Point at repo.vates.tech for CentOS since mirrorlist.centos.org was cut
                            * Add "(EOL)" to repo descriptions for EOL repos
                            * Drop unused repos

                      Test on XCP-ng 8.2

                      yum clean metadata --enablerepo=xcp-ng-candidates
yum update "xen-*" microcode_ctl xcp-ng-release --enablerepo=xcp-ng-candidates
reboot

                      The usual update rules apply: pool coordinator first, etc.

                      Versions:

                      • xen: 4.13.5-9.44.1.xcpng8.2
                      • microcode_ctl: microcode_ctl-2.1-26.xs29.5.xcpng8.2

                        @bleader Update worked well on my two node homelab and everything looks and works normal after reboot. I did some basic stuff like VM and Storage migration, but nothing in depth. Let's see how things work out.

                          @bleader I installed it on many 8.2 machines. On one I did get a warning:

                            Cleanup    : xen-libs-4.13.5-9.40.3.xcpng8.2.x86_64                     14/14

  Verifying  : xcp-ng-release-8.2.1-13.x86_64                              1/14

                          But it did not seem to have any effect. Nothing extra in the yum.log

                            @Andrew If I understand correctly that is ran after regenerating the initrd, but to be sure, can you check the date of your /boot/initrd-4.19.0+1.img on this host?

                              Here's what the posttrans scriptlet exactly executes:

                                  dracut -f /boot/initrd-4.19.0+1.img 4.19.0+1 
    udevadm trigger --attr-nomatch=driver && udevadm settle -t 30

                                So if the initrd has been regenerated, it's likely the second part that fails, otherwise it is dracut, which is more of an issue.

                                  @bleader @stormi Microcode was updated and initrd was rebuilt correctly and the system rebooted with the updates, so I don't know what the error was. Running the commands manually produces no errors. Maybe the system was busy and it was the shorter 30 second settle timeout (vs. the default 120 seconds), at this time it returns quickly.

                                  The warning was only on one system (out of 5 identical pool hosts) but caused no actual issues.

                                      New update candidates for you to test!

                                      As you may know, we group non-urgent updates together for a collective release, in order not to cause unnecessary maintenance for our users.

                                      The moment to release such a batch has come, so here they are, ready for user tests before the final release.

                                      • XAPI:
                                        • Synced with XS82ECU1074

                                            • Performing a hard shutdown of a VM may hang due to unnecessary RBCA permission checks. An icon (yellow triangle) may then be displayed on some management applications, indicating that the shutdown process did not complete successfully.
                                            • Canceling a hard shutdown of a hung VM fails because the cancel function only checks for proper shutdowns.
                                            • Migrating VMs from 8.2.1 to 8.3 with the xe vm-migrate command may fail with the error 'Failure: Unknown tag/contents'.
                                            • You may encounter a 500 error (internal server error) when trying to retrieve RRD measurements from a powered off virtual machine.

                                      From an up to date host:

                                      yum clean metadata --enablerepo=xcp-ng-testing,xcp-ng-candidates
yum update --enablerepo=xcp-ng-testing,xcp-ng-candidates
reboot

                                      The usual update rules apply: pool coordinator first, etc.

                                      What to test

                                      Normal use and anything else you want to test. The closer to your actual use of XCP-ng, the better.

                                      Test window before official release of the updates

                                      ~1 week.
