Reiser4 Kernel 4.15.15 and Upgraded wireless-regdb for Debian AMD64




Niltze-

Built reiser4 enhanced Linux 4.15.15 wrapped by Debian packaging for kernel 4.15.11 (last I found) modified for GCC6 stretch-backports AMD64.

Upon booting kernel in wireless maching, it complained about:

platform regulatory.0: firmware: failed to load regulatory.db (-2)
[   12.134223] firmware_class: See https://wiki.debian.org/Firmware for information about missing firmware
[   12.134281] platform regulatory.0: Direct firmware load for regulatory.db failed with error -2
[   12.134283] cfg80211: failed to load regulatory.db

Doing an online search it seems this is a 'feature' of kernels 4.15.x, i.e., below is for Slackware:

< https://www.linuxquestions.org/questions/linux-kernel-70/kernel-platform-regulatory-0-direct-firmware-load-for-regulatory-db-failed-with-error-2-a-4175622954/ >

Notwithstanding, Debian seems to be lacking relevant files in ~2016 (last/latest) wireless-regdb package.

Although I created a repo at Github

< https://metztli.github.io/wireless-regdb-metztli/ .

there is only a small hack to debian-example in git source for wireless-regdb, from upstream, thus created attached patch for

git clone git://git.kernel.org/pub/scm/linux/kernel/git/sforshee/wireless-regdb.git

cd wireless-regdb

cat debian-upgraded-regulatory-regdb-for-4.15x.patch | patch -p1

dpkg-buildpackage -F -us -uc -j2 -T binary

./usr/share/doc/wireless-regdb/
./usr/share/doc/wireless-regdb/README
./usr/share/doc/wireless-regdb/changelog.Debian.gz
./usr/share/doc/wireless-regdb/copyright

Of course, also
apt-get install crda
as it is recent from Debian repositories.

I built *both* packages (nmu .1 and -1) and made available *without* guarantee to solve your particular relevant issue:

https://metztli.it/readOnlyEphemeral/wireless-regdb_2018.04.02-1_all.deb

https://metztli.it/readOnlyEphemeral/crda_3.18-1.1_amd64.deb

They fix the above wireless regulatory.db issue(s) in my machine.


Best Professional Regards.
