As of kernel 4.15 the wireless stack now complains if regulatory.db isn't provided: platform regulatory.0: Direct firmware load for regulatory.db failed with error -2 cfg80211: failed to load regulatory.db This file can be generated through a new wireless-regdb package https://www.kernel.org/pub/software/network/wireless-regdb/wireless-regdb-2017.12.23.tar.xz The resulting file needs to go in /lib/firmware the following kernel options need to be enabled to use it CFG80211_CERTIFICATION_ONUS=y CFG80211_REQUIRE_SIGNED_REGDB=n in order to load the file without a signature Not setting those meant I had to also include regulatory.db.p7s which the kernel then complained about not being trusted as the make file in wireless-regdb just self signs
Created attachment 513728 [details] wireless-regdb-20171223.ebuild Try this on for size. All I did was bump the ebuild, and copy those 2 files to the /lib/firmware directory (without rebuilding the database).
Created attachment 515752 [details] wireless-regdb-20171223.ebuild Fixed typo and added bug number.

Straight to stable as per the precedent set by previous commits from Richard "Zero-Chaos" Farina.

The signature isn't required if these options are set: CFG80211_CERTIFICATION_ONUS=y CFG80211_REQUIRE_SIGNED_REGDB=n
Currently this is what the ebuild installs: equery f wireless-regdb * Searching for wireless-regdb ... * Contents of net-wireless/wireless-regdb-20171223: /etc /etc/wireless-regdb /etc/wireless-regdb/pubkeys /etc/wireless-regdb/pubkeys/sforshee.key.pub.pem /usr /usr/lib /usr/lib/crda /usr/lib/crda/regulatory.bin /usr/share /usr/share/doc /usr/share/doc/wireless-regdb-20171223 /usr/share/doc/wireless-regdb-20171223/README.bz2 /usr/share/doc/wireless-regdb-20171223/db.txt.bz2 /usr/share/man /usr/share/man/man5 /usr/share/man/man5/regulatory.bin.5.bz2 So no /lib/firmware/regulatory.db
(In reply to Mike Lothian from comment #6) > The signature isn't required if these options are set: > CFG80211_CERTIFICATION_ONUS=y > CFG80211_REQUIRE_SIGNED_REGDB=n Which is a non-standard setup. What is installed should cope with an untweaked kernel.
Sorry my comment was in relation to net-wireless/wireless-regdb-20171223 not net-wireless/wireless-regdb-20171223-r1, all files now in place Thanks
I still get the following output with wireless-regdb-20171223-r1, is there any relevant kernel config option that should be switched on as well? [ 1.398297] Loading compiled-in X.509 certificates [ 1.399866] rtc_cmos 00:03: setting system clock to 2018-01-29 14:59:26 UTC (1517237966) [ 1.399956] cfg80211: Loading compiled-in X.509 certificates for regulatory database [ 1.400753] cfg80211: Loaded X.509 cert 'sforshee: 00b28ddf47aef9cea7' [ 1.400784] platform regulatory.0: Direct firmware load for regulatory.db failed with error -2 [ 1.400785] cfg80211: failed to load regulatory.db
Never mind, I had cfg80211 built into the kernel. Either the firmware should be embedded as well, or cfg80211 should be built as a module.
thanks Tony!
