Bug Description

SRU Justification

[Impact]

The linux-azure 6.2 kernel doesn't report a correct GUEST_ID

There is a mistake in the commit (https://git.launchpad.net/~canonical-kernel/ubuntu/+source/linux-azure/+git/jammy/commit/?id=5dd24f2df3280d4354641f4687dbb36e418e7de8) :

Before the commit, the good guest_id is 0x8180000602100000.

With the commit, the generated guest_id is incorrect: 0x0080000602100000, i.e. the 0x81 from bit 56~63 are dropped.

See "include/asm-generic/hyperv-tlfs.h" for the definition of the bits:
* Bit(s)
* 63 - Indicates if the OS is Open Source or not; 1 is Open Source

* 62:56 - Os Type; Linux is 0x100 !!!!! Dexuan: this should be 0x1. I'll post a patch to LKML to fix this typo.

* 55:48 - Distro specific identification
* 47:16 - Linux kernel version number
* 15:0 - Distro specific identification

See https://learn.microsoft.com/en-us/virtualization/hyper-v-on-windows/tlfs/tlfs ("February, 2020: Released Version 6.0b", page 15)

As a result, the host thinks that the VM is not an open-source OS, and it's not Linux. Consequently, the "VM Availability" fron Azure portal is 0 (unhealthy): some users rely on the info to manage their VMs, e.g. if the VM is erroneously reported "unhealthy", the VM may be killed and re-created, and the new VM is still "unhealthy", and the VM may be killed and re-created again...

Please consider integrating the below fix ASAP. This affects regular VMs, and I think this affects CVMs as well.

The fix should be:

diff --git a/include/asm-generic/hyperv-tlfs.h b/include/asm-generic/hyperv-tlfs.h
@@ -135,7 +135,7 @@ union hv_reference_tsc_msr {
*
*/

-#define HV_LINUX_VENDOR_ID 0x80 /* Canonical */
+#define HV_LINUX_VENDOR_ID 0x8180 /* Canonical */

[Test Plan]

Microsoft tested

[Regression Potential]

VMs could be misclassified.

We use the Ubuntu Server 22.04 LTS image from Azure Marketplace in several virtual machine scale sets. The vmss's are marked as Unhealthy due to the bug. The product id in Azure Marketplace is "0001-com-ubuntu-server-jammy" and I wonder if the patch being discussed here will apply to that image on Azure Marketplace? I get the impression that jammy version is excluded.
