Ports an OpenWRT patch for Atheros wireless drivers (ath*) which allows
the user to change the regulatory domain code to the one which actually
applies.
All Atheros devices have a regulatory domain burned into their EEPROM.
When using a device as AP, this domain is frequently overly restrictive
when compared to the regulation which applies in the country the device
actually operates in; often, this restriction disallows IR on all
channels making it impossible to use the device as an AP at all.
This commit introduces the NixOS config option
networking.wireless.athUserRegulatoryDomain which, if enabled, applies
the patch and sets the kernel config option ATH_USER_REGD.
The original OpenWRT patch targets Linux 5.8.
This will avoid breaking the build whenever a non-major kernel update
happens. In the update script, we map each kernel version to the latest
patch for the latest kernel version less than or equal to what we
have packaged.
This is an updated version of the former upstream,
https://github.com/AndroidHardeningArchive/linux-hardened, and provides
a minimal set of additional hardening patches on top of upstream.
The patch already incorporates many of our hardened profile defaults,
and releases are timely (Linux 5.5.15 and 5.6.2 were released on
2020-04-02; linux-hardened patches for them came out on 2020-04-03 and
2020-04-04 respectively).
In 5.0er these function were removed from the public interface also zfs needs
them for AVX/AES-NI support. Without this patch for example throughput on a
encrypted zfs dataset drops to 200 MB/s from 1.2 GB/s. These functions were
removed as their was no user within the linux kernel tree itself.
This reverts commit de86af48faa03a824917ac90f4776481c7ce9e54.
(Manual revert due to conflicts.)
See #54509
The patch is causing overlayfs to misbehave.
Fix a serious issue with the xen-netfront driver introduced in
upstream commit f599c64fdf7d ("xen-netfront: Fix race between device
setup and open") where the MTU of the device cannot be set
properly. This should be removed once it's included in upstream.
Currently, moving to kernel_4_14 breaks at least Intel Wireless 8260 and
8265 cards due to a API change in the firmware, which is not yet honored
in the driver.
There is no maintainer for this package, probably not many users.
It requires effort to fix all third-party modules for this old kernel
versions. It might contain unpatched security holes.
For Pixel chromebooks, we have the samus-kernel.
Apart from that https://github.com/GalliumOS/linux might be a good choice.
