Please refer to https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.15.57
for the changelog of this version. Since it introduces
architecture-dependent rootfile changes due to CPU side-channel
mitigations, changes to ARM rootfiles have been omitted due to the lack
of hardware.
Supposed hardening changes will be submitted separately.

This patch, which has been merged into the mainline Linux kernel, but
not yet backported to the 5.15.x tree, precisely addresses our
situation: IPFire does not use systemd, but CONFIG_DEVTMPFS_MOUNT.
The only explanation I have for bug #12889 arising _now_ is that some
component (dracut, maybe) changed its behaviour regarding remounting of
already mounted special file systems. As current dracut won't (re)mount
any file system already found to be mounted, this means that the mount
options decided by the kernel remained untouched for /dev, hence being
weak in terms of options hardening possible.
As CONFIG_DEVTMPFS_SAFE would not show up in "make menuconfig", changes
to kernel configurations have been simulated.
Fixes: #12889

in kernel 5.15.32 the driver for ATH9K wlan cards is unstable.
This is one of the most used cards so we need this update before
releasing core167 final.

flashrom needs access to /dev/io ports for flashing firmware, a
functionality we cannot cease to support. Therefore, LSM constraints are
disabled for ioport.c, hopefully permitting us to keep it enabled.

This is recommended by KSPP, Lynis, and others. Indeed, there is no
legitimate reason why an unprivileged user on IPFire should do any
profiling. Unfortunately, this change never landed in the mainline
kernel, hence a distribution patch is necessary.
The second version of this patch rebases the kernel patch by Jeff
Vander Stoep against Linux 5.15.17 to avoid fuzzying.

Historically, the MD5 checksums in our LFS files serve as a protection
against broken downloads, or accidentally corrupted source files.
While the sources are nowadays downloaded via HTTPS, it make sense to
beef up integrity protection for them, since transparently intercepting
TLS is believed to be feasible for more powerful actors, and the state
of the public PKI ecosystem is clearly not helping.
Therefore, this patch switches from MD5 to BLAKE2, updating all LFS
files as well as make.sh to deal with this checksum algorithm. BLAKE2 is
notably faster (and more secure) than SHA2, so the performance penalty
introduced by this patch is negligible, if noticeable at all.
In preparation of this patch, the toolchain files currently used have
been supplied with BLAKE2 checksums as well on
https://source.ipfire.org/.

This kernel configuration is a copy of our kernel configuration for
x86_64 on which I ran "make olddefconfig" which will set any unknown
values to their defaults.
This exists so that we have some kernel (which I did not try to boot) to
complete the build process.

Bumping across one of our scripts with very long trailing whitespaces, I
thought it might be a good idea to clean these up. Doing so, some
missing or inconsistent licence headers were fixed.
There is no need in shipping all these files en bloc, as their
functionality won't change.

This patch removes support for i586 according to the decision being
taken over a year ago.
It removes the architecture from the build system and removes all
required hacks and other quirks that have been necessary before.
There is no need to ship any changed files to the remaining
architectures as the removed code branches have not been used.
