Public bug reported:
[Impact]
New upstream release. This is a database of wireless regulations, and
should updated in all releases to ensure users have the most up-to-date
regulatory information.
[Test Case]
On baremetal or a VM, running the LTS kernel, install the new wireless-
regdb version.
Following reboot after installing the new database, it should be
possible to query and change the regulatory domain using 'iw reg get'
and 'iw reg set'.
If your system doesn't have a wireless interface, you can simulate one with the
mac80211_hwsim module so the cfg80211 driver can load:
```
sudo apt install linux-modules-extra-$(uname -r)
sudo modprobe mac80211_hwsim
```
Ensure there are no error messages in the dmesg log.
To test changing the db, run:
```
sudo apt install iw
sudo iw reg reload # just to be safe
iw reg get # should return current db info
sudo iw reg set <COUNTRY> # e.g. US
iw reg get # should return db info for selected country
```
[Where problems could occur]
If crda (<< k4.15) or the kernel is unable to use the new database,
users may be stuck using the default "world" regulatory domain which is
quite restrictive, therefore they may be unable to use wireless channels
that they were able to use previously. Regulatory rules may have also
changed for the user's region, which could also make some channels
unusable, but this would not be a bug.
In 24.04, there was also a bug where this deb package comes preinstalled
on Ubuntu Desktop FDE images. This behavior was incorrect because
wireless-regdb is included in the kernel snap, not the deb. Thus, future
installs failed because it attempts to modify /lib/firmware which is RO
on hybrid systems. The proper Conflicts have been declared in wireless-
regdb, and boot-managed-by-snapd versions >= 5 should not have this
issue.
On systems where the kernel handles verifying the signature instead of
CRDA, the key must be included in the kernel tree.
