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- 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.

[Kernel-packages] [Bug 1877270] Re: Devlink - add RoCE disable kernel support
Hi Jeff, the following patch need to be included in the patch set. 4cca96a8d9da IB/mlx5: Do reverse sequence during device removal without it devlink dev reload operation causes a double free of cache memory and leaves the kernel in a state that requires a restart. the patch is applied cleanly above ubuntu-focal tree.

[Impact]
RoCE disable feature was added to the kernel v5.5.
This feature was requested by Mellanox customers that use Ubuntu 20.04,

RoCE enablement state controls driver support for RoCE traffic.
When RoCE is disabled, there is no gid table, only raw ethernet QPs are

To change RoCE enablement state a user must change the driverinit cmode
value and run devlink reload.

[Kernel-packages] [Bug 1877270] Re: Devlink - add RoCE disable kernel support
Hi Jeff,
after testing the feature we see that some devlink functionality is missing in
our driver and we must add them before adding the ROCE feature.
This missing functionality is the implementation of devlink reload and
it was introduced upstream by the following two patches:
4383cfcc65e7 ("net/mlx5: Add devlink reload")
32680da71034 ("net/mlx5: Remove unneeded variable in mlx5_unload_one")
the above patches applied cleanly over your tree but we have some
compiling issue since the following patch are missing:
070c63f20f6c ("net: devlink: allow to change namespaces during reload")
these compiling issues can be resolved by aligned
mlx5_devlink_reload_down to Focal devlink_ops->reload_down by removing
the 'bool netns_change' parameter from mlx5_devlink_reload_down
function.
Thanks,
