** Description changed: [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] 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'. + + After installing the new version of wireless-regdb, run: + + ``` + sudo apt install iw + 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 + ``` + + You can also test this on a VM, but you'll need to first load the + mac80211_hwsim module: + + ``` + sudo apt install linux-modules-extra-$(uname -r) + sudo modprobe mac80211_hwsim + ``` [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.
