Arch Linux User Repository

A fix for Linux 5.0 has been merged upstream and I've bumped the version.

inline patch... no version check, so not the best... but if you're on the new 5x kernel and need this https://gist.github.com/b1tninja/18b65b21eb849af32e3a4a20ba4be545

I didn't have any issue while running yay -Syu and upgrading to the 5.0 kernel. But after that, the RTL8821CE 802.11ac PCIe Wireless Network Adapter is not seen with ip addr but is still listed with lspci. What should I do now?

Fix for trouble with update to 5.0 kernel

In (629:24) ./rtl8821ce/os_dep/linux/rtw_android.c remove first parameter

if (!access_ok(VERIFY_READ, priv_cmd.buf, priv_cmd.total_len))

to

if (!access_ok(priv_cmd.buf, priv_cmd.total_len))

Somehow the DKMS fails to build because of:

/var/lib/dkms/rtl8821ce/1.0.1.r28.g960279a/build/core/rtw_debug.c: In function ‘dump_drv_version’:

But magically installing bc package solves this problem... Weird...

@Knecker really glad to hear that! Thanks for the kind words :)

I just came by to thank you very very much for this driver package! Without, I could not have made the switch from Windows to Linux and now I am running with Manjaro / Arch and left the evil times behind :) So again, thank you very much for your efforts!

That fixed it, many thanks :-)

And again thanks for maintaining this.

@swillber this had already been fixed upstream (master branch), but I forgot to bump the version in AUR. Sorry! Could you try again?

Getting a build error since the release of kernel 4.20 before that it was fine. Many thanks for providing this. Don't know if it's directly due kernel changes or something else that's changed because of the new kernel release. Is this the right place to report this or if I should feedback via github?

Here's an extract from /var/lib/dkms/rtl8821ce/1.0.1.r18.g8c9149a/build/make.log that has the only error message I can see...
