Bug Description
SRU Justification
[Impact]
focal/linux-azure is missing a number of config options compared to impish/linux-azure. This kernel is also missing 2 patches that significantly impact network performance.
From Microsoft:
We tested this kernel. The P0P1 test cases are finished. Below are we found. P2 test cases are still running. I will update you when they are finished.
1. From dmesg, we can see following lines. Could you check why it has these messages and if the messages impact the system?
[ 3.341802] squashfs: SQUASHFS error: Xattrs in filesystem, these will be ignored
[ 3.346056] unable to read xattr id index table
2. The kernel hasn't backport Michael's SRIOV performance improvement patches. The network performance is not expected.
Here are the patches:

3. It is failed to create raid 0 using below command.
# mdadm --create /dev/md0 --level 0 --raid-devices 16 /dev/sd[
mdadm: Defaulting to version 1.2 metadata
mdadm: RUN_ARRAY failed: Invalid argument
From dmesg, it has following lines:
[ 235.830712] md: personality for level 0 is not loaded!
[ 235.830733] md: md0 stopped.
I see many raid related configuration is not set. Could you check the raid related and other configuration?
# cat /boot/config-
CONFIG_RAID_ATTRS=m
# CONFIG_
# CONFIG_SCSI_AACRAID is not set
# CONFIG_
# CONFIG_
CONFIG_
# CONFIG_SCSI_PMCRAID is not set
# CONFIG_MD_RAID0 is not set
# CONFIG_MD_RAID1 is not set
# CONFIG_MD_RAID10 is not set
# CONFIG_MD_RAID456 is not set
# CONFIG_DM_RAID is not set

[Test Case]
Microsoft tested
[Where things could go wrong]
There should be little chance of regression given that these are config options.

This bug is awaiting verification that the linux-azure/ 5.4.0-1077. 80 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- focal' to 'verification- done-focal' . If the problem still exists, change the tag 'verification- needed- focal' to 'verification- failed- focal'.
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. Thank you!
