[Bug 1884648] Re: rtl8821ce 5.5.2.1-0ubuntu3 ADT test failure with linux-5.8 5.8.0-1.2

[Chris Halse Rogers]

Hello Seth, or anyone else affected,

Accepted rtl8821ce into focal-proposed. The package will build now and
be available at
https://launchpad.net/ubuntu/+source/rtl8821ce/5.5.2.1-0ubuntu4~20.04.2
in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
focal to verification-done-focal. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-focal. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Bug description:
  [SRU Justification]

  [Impact]
  rtl9921ce-dkms may fail to compile dkms modules on devices with v5.5 kernel or newer due to kernel data structure changes.

  [Fix]
  Following changes required with modifications to fix such errors:
  * commit ff74b75511c5 ("convert file_operations structs to proc_ops structs for compatibility with linux 5.6") from https://github.com/tomaspinho/rtl8821ce .
  * commit 5e7d1302d3c4 (".mgmt_frame_register -> .update_mgmt_frame_registrations")  from https://github.com/tomaspinho/rtl8821ce .
  * Additional fix to "core/rtw_security.c" for v5.8 kernels.

  [Test Case]
  Verified with kernels:
  * 5.4.0-26-generic
  * 5.6.0-1010-oem
  * 5.7.0-9-generic
  * 5.8.0-1-generic

  [Regression Potential]
  Low. The patches are to adopt new interface changes when compiled against new kernels. For existing users with older kernels, they're not affected. For those with new kernels they're still fine as that's what new kernels do.
