Updates announcements and testing
-
@stormi Nice work and the joint effort by the community for tests gets better every time
. Keep up the good work 
. Updated my (semi production) three host homelab and it works - as usual. Now it is time to tear down my playlab for some 10G testing

Hi @stormi is there any easy way to rollback the September updates??? I'm guessing not but I have a strange issue which I think coincides with my last reboot after applying the updates so want to confirm or eliminate as the cause.
Thanks.
-
@jmccoy555 Have a look at
yum history. You should find the update listed and be able to rollback.Another way is to use
yum downgrade package-1version-release package2-version-releaseon every package involved in the update (list found inyum historyor/var/log/yum.log). -
Note (for you or anyone coming here later): rollback/downgrade is not officially supported, because it's not tested, and it is not always possible to ensure that it really brings the exact previous state. You wouldn't rollback a XAPI update that modified the structure of the XAPI db, for example. However for many packages it's safe to attempt it. The September update, that only contains xen packages IIRC, is one of the updates that should be easy and safe to revert.

@stormi thanks as always. If I do find the issue I'll let you know..... if I break everything then I'll just get a
-
It appears that the rollback worked, but doesn't appear to have an impact on my issue, which is good news in a way.

Let's test the next train of updates
I have various updates ready and tested internally that are eager to be pushed officially. All they need is a bit of user feedback, and that's why we're all on this thread right?
What changes
- Updated
ca-certificatesremoves an expired root certificate that was used by Let's Encrypt, in order to workaround a limitation of the old version of openssl included in XCP-ng when the chain of trust contains an expired certificate, even when another path would allow to verify the certificate. Basically, this just means thatwgetwould fail on most HTTPS URLs that use a Let's Encrypt certificate, and now it won't fail anymore. - Updated
kernel(bugfix update, already detailed above and tested by some of you)
Update (2021-10-27): new patches synced from new [Citrix hotfix](https://support.citrix.com/article/CTX330706). Removes spurious kernel warnings and supposedly increases the "resiliency" of the kernel (ie, bugs were fixed). - Updated
grubfixes a booting issue with buggy UEFI firmware that only wants to boot fromEFI/BOOT/BOOTX64.EFI... Or worse, firmware that doesn't really boot from this file but won't boot if the file doesn't exist... - Updated
xcp-featuredfixes a bug that made the Pool Secret Rotation feature (something you rarely need - as no one reported the issue - but can be useful sometimes) unavailable. - Updated
guest-templates-json*packages add a VM template for Rocky Linux. It's not really different from the template for CentOS 8, but should please Rocky users. - Updated
xcp-ng-release*packages bring small fixes to the XOA deploy feature on host landing web pages, and update jquery to fix an XSS vulnerability in this library.
How to update
yum clean metadata --enablerepo=xcp-ng-testing yum update ca-certificates grub grub-efi grub-tools guest-templates-json guest-templates-json-data-linux guest-templates-json-data-other guest-templates-json-data-windows kernel xcp-featured xcp-ng-release xcp-ng-release-config xcp-ng-release-presets --enablerepo=xcp-ng-testingThen reboot.
What to test
The same as usual: installation of the update, normal use, check that you find no obvious regressions... This is the most important.
And optionnally the changes described above if you're in a situation that allows it.
Test window before release
A few days.
What's not included in this update train
The XAPI update is not included yet due to a regression found during the tests: our landing web page was completely broken when loaded in HTTPS (which becomes the only way as HTTP is disabled with this update). We identified the issue and contributed a fix to the XAPI project. There's still some work to do internally before we can release it confidently.

Hello are you using i40e driver for your network card?

@stormi
I just installed the updates and have not had any issues this far, will have an eye on the systemfor the next few days and report back if I notice something different.PS you must add
--enablerepo=xcp-ng-testingto theyum updatecommand, otherwise it will not install the new packages from the test repo
-
@heman Thanks, fixing!
-
@stormi Updated and rebooted. I'll report back if I encounter any issues.
-
@stormi
Working well for me so far. -
So, Citrix published a new kernel hotfix yesterday, so I synced our kernel package to it. As a result, there's a new
kernelpackage in the testing repository, so please update again if you had updated already
yum clean metadata --enablerepo=xcp-ng-testing yum update kernel --enablerepo=xcp-ng-testingAnyone else, just follow the instructions of the big post above, you'll get the new kernel with the other updates.
I'll update the big post with details about the new kernel update.
-
@stormi installed this new kernel as well and rebooted.
Still no regression issues found till now. -
@stormi All new patches applied fine. No apparent problems identified so far.
-
@stormi So far, so good for my systems with the re-updated kernel.
-
A big thank you to those who tested, and last call for the others! Publish time is close.

If you are wondering "how close", I delayed them a bit to potentially group them with another update.

Hi @stormi
Any idea how long "a bit" is?
Cheers!

The updates I wanted to group them with did not come, so it all got delayed (and retrospectively I could have released them earlier).
Are you waiting for a specific fix?
