Fixes kernel v5.17 rc1 and above

[v3rlly]

Fixed issues related to Linux Kernel changes from v5.17 rc1

[realFlowControl]

I can confirm that this PR makes the module compile and work on Kernel 5.17.4 in current Fedora

[matthewsgj]

I just compiled on Pop-OS! with kernel 5.17.5 (5.17.5-76051705-generic). Builds and installs fine and my wifi dongle runs happily on it. Thanks for the fix.

Does not work on Kali with kernel 5.18

[s0kil]

Also does not work with 5.19

[Jeffmagma]

I still get an error with kthread_complete_and_exit, it says did you mean complete_and_exit? I'm on 5.15, running Ubuntu 22.04

[matthewsgj]

Just tried to compile on Pop!_OS 22.04 LTS with kernel 6.0.6-76060006-generic and got the errors below:

[FabienDanieau]

I had the same issue. I made few changes and was able to compile the driver for Debian 12 with a kernel 6.0
v3rlly#1

[matthewsgj]

Thanks Fabien. That has compiled fine on my system.
Cheers, :)

main_to_knl_6-0-0.diff.gz
I've gone back over these various patches because some cause errors with older kernels and I've refactored some of the code so that it now compiles against the kernels on my Debian (5.10), my Kali (5.18) and my Pop!_OS (6.0) systems.
Maybe it is of use to someone.

I am sorry to ask in here for help, but i have a TP-Link Archer T9UH with the RTL8814AU, and am on Arch, would like to use this Stick with Monitor and Packet Injection.. im just having quite a lot of difficulties figuring out how to build this probably fixed version that includes this PR.. would anyone be kind enough to potentially help me get through this? So like, write up a few commands on how to grab the code from this pull request via git clone and such?

[realFlowControl]

Hey @TheCustomFHD, I switched to https://github.com/morrownr/8814au recently

[TheCustomFHD]

@realFlowControl , thanks for the answer, im wondering, does this one support packet injection? It states monitor mode, but im unsure about packet injection.

[matthewsgj]

@realFlowControl , I packaged up all the changes that work into a patch linked above. So if you clone the v5.8 main repository, then download my patch and drop it into the cloned directory, unzip it and run:
$ patch -p1 < main_to_knl_6-0-0.diff

I have the same TP-Link dongle and this works for me on various kernels up to 6.0.6. Good luck!
