[SOLVED] Issue with loading regulatory.db at boot
[5.0.9-arch1-1-ARCH]
Examining logged kernel messages right after boot, I see the two consecutive lines:
[ 2.505562] platform regulatory.0: Direct firmware load for regulatory.db failed with error -2
[ 2.505564] cfg80211: failed to load regulatory.db
I looked up topics and contents of post on this BBS and elsewhere, containing: failed AND load AND regulatory.db.
There is a lot of stuff out there, but I am no closer to finding out why regulatory.db failed and how to fix it.

Re: [SOLVED] Issue with loading regulatory.db at boot
Respecting_the_regulatory_domain. wireless-regdb provides regulatory.db and is a dependency of crda.

Re: [SOLVED] Issue with loading regulatory.db at boot
I do not have the agent core/crda installed, and:
$ iw reg get
global
country 00: DFS-UNSET
(2402 - 2472 @ 40), (6, 20), (N/A)
(2457 - 2482 @ 20), (6, 20), (N/A), AUTO-BW, PASSIVE-SCAN
(2474 - 2494 @ 20), (6, 20), (N/A), NO-OFDM, PASSIVE-SCAN
(5170 - 5250 @ 80), (6, 20), (N/A), AUTO-BW, PASSIVE-SCAN
(5250 - 5330 @ 80), (6, 20), (0 ms), DFS, AUTO-BW, PASSIVE-SCAN
(5490 - 5730 @ 160), (6, 20), (0 ms), DFS, PASSIVE-SCAN
(5735 - 5835 @ 80), (6, 20), (N/A), PASSIVE-SCAN
(57240 - 63720 @ 2160), (N/A, 0), (N/A)
I also checked that for my Atheros interface device:
$ dmesg | grep ath:
[ 3.269711] ath: Country alpha2 being used: 00
Default setting is 00 for global, while I’m in western Europe.
(Could that begin to explain why my WiFi connection *always* tops at 1Mbps, even as I sit next to the access point.)
I installed crda (and dependency wireless-regdb), uncommented the appropriate region in /etc/conf.d/wireless-regdom and will reboot now…

Re: [SOLVED] Issue with loading regulatory.db at boot
gives me the right country (although the question here becomes what if I travel to a different country tomorrow, do I need to change this by hand every time I hop in and out of a plane ?), and the original messages in dmesg are gone.
So that’s that, but
seems to be stuck on ’00’.

Re: [SOLVED] Issue with loading regulatory.db at boot
If you legally bought the NIC in your regulatory domain («Country») you don’t have to do *anything* — just ignore the message, it’s irrelevant.
If you want to tamper w/ the regdb, eg. because you’re legally required to adapt to the reg domain (and accordingly configured router) in a different country, you’ll have to install and enable crda (same goes for all other, not so legal reasons) and load the proper configuration for the reg domain you enter, yes.
Luckily the differences are not that massive, esp. on the 2.4GHz band, https://en.wikipedia.org/wiki/List_of_WLAN_channels (pay attention to TX power limitations, though)
You’re oblieged to use legal channels, whether or not this is driven by a correct database entry, let alone w/ the proper 2-letter country code is completely irrelevant.
So, to sum up:
If you stay at home, don’t worry, all is fine as it came out of the box (unless the box fell of a chinese truck
If you travel around, the easiest solution is crda and configure the correct reg domain — obviously using eg. geoip to configure that automgically is not a perfectly legal solution, since you first need an IP to figure your location

Re: [SOLVED] Issue with loading regulatory.db at boot
Seth:
;-))) Unfortunately my box did NOT fall off the back of a truck. It would have been significantly cheaper… It was made in China and so was its Qualcom ATH10k wifi device, but yes legally imported and sold to me in Europe.
So maybe that is the reason it was set to ’00’ by default, probably in an EEPROM directly on device. I’m only guessing here, based on the fact I cannot change the ’00’ value associated to my Atheros wifi device.)
That is inconvenient because I do travel and I’d like to take advantage of the fact that Tx power limits are higher int the US than in Europe (channels are less a problem, especially in the 2.4GHz range as you rightly pointed out).
You’re saying that with a little script using geoIP I could have my machine read its current location country and configure the reg domain on the fly. Did I understand you well ? Doing so would require reboot I think, so again that would not be hot config and on the fly.
Tx. Query SOLVED.

Re: [SOLVED] Issue with loading regulatory.db at boot
If the device was legally imported, the default behavior is ok in the destination region (regardless where the chip was etched)
You do not have to reboot, crda allows you to alter the regdomain on the fly (see the link loqs posted). The legally «wonky» part is that if you wanted to use geoip to determine the location, you first would have to use the radio (to get an IP) and in this pot. violating the law. Though to be realistic, exceeding the tx power limits for some minutes will usually go unnoticed anyway and violating radio standards is usually not punished by hang, draw & quarter either.

Re: [SOLVED] Issue with loading regulatory.db at boot
I re-open this question momentarily. Something cropped up.
Since I’m in Western Europe, I wanted to put in a country code to that effect, e.g. «EU». Although «EU» is already «unofficially» considered by the ISO 3166-1, «EU» is not included/available in /etc/conf.d/wireless-regdom. I added it yesterday and curiously, upon rebooting (that was yesterday), the actual code of the actual EU country in which I am right now popped up as the result of
The question that comes to mind is: how does detection occur ?
I am especially interested in that because I generally work behind a proxy (sometimes it’s a tor node sometimes a VPN service), with a choice of exit nodes, unrelated to my geographical location. So by what magical process was the name of my actual location country ?
As it turns out:
— Inserting WIRELESS_REGDOM=»EU» in /etc/conf.d/wireless-regdom is ignored.
— Upon booting, early this morning: (i) my actual country location was not detected; (ii) it remained ’00’ or global as it is hard set on EEPROM; (iii) Basically the effect of installing crda is to suppress the dmesg failure notification, as mentioned in post#1, about not loading regulatory.db.
Case closed.

So which of these filemanes would I need to add to the CONFIG_EXTRA_FIRMWARE?

According to Gentoo Wiki the CONFIG_EXTRA_FIRMWARE and CONFIG_EXTRA_FIRMWARE_DIR options need to be set to the values identified by iucode_tool. For example:

How does that conflict with my advice? You can list multiple things in CONFIG_EXTRA_FIRMWARE, so it is fine to list both the microcode file and the requested wireless database. |

Well, you may need to list regulatory.db in CONFIG_EXTRA_FIRMWARE in case the wireless configuration API (CONFIG_CFG80211) is built into the kernel (<*>) instead as a module (<M>). Otherwise there is no need to add yet another blob to the kernel. |

I’m seemingly experiencing this bug too on the exact same kernel version 5.3.1-arch1-1-ARCH. The BUG: kernel NULL pointer dereference, address: 00000000000008c0
seems to be the pertinent part, or at least is what is highlighted in red in dmesg
.
I also get a seemingly similar stacktrace when installing https://github.com/zebulon2/rtl8814au. Speaking of what’s the difference between those projects?
Here is my stack trace: https://gist.github.com/henrywallace/cb8bb75e1be21abaa71ad13e62264850
It also looks like there are repeated segments? I’m curious if that was just the kernel module attempting to be loaded multiple times. I’m a kernel module noob. Any pointers on how to read or debug these kinds of things?

This issue and #421 may be same.
Your stack trace and mine has WARNING: CPU: 1 PID: 42 at net/wireless/core.c:868 wiphy_register.cold+0x37/0x435 [cfg80211]
.
This was referenced
Oct 6, 2019
v5.6.4.1
has the fix merged (#424). Please rebuild from this branch and try again.
Can confirm, fixed for me. Note, too there seems to be many duplicates of this same bug across different issues, briefly overviewing the github issues.
Move over to v5.6.4.2 instead of v5.6.4.1

DED54, вроде все нормально, криминала не видно — все должно работать. Трудно что то сказать, тем более не зная, что же у тебя за устройство (VID:PID так и не показал). Расчитывать на готовое решение в этом случае бесполезно, совет может дать только тот, кто использовал данный девайс.

Не понятно, почему не показывает lsusb. А не пробовал Live CD, например, ubuntu или винду, если стоит? Устройство вообще работает? Чтобы идти дальше, нужно убедиться что устройство Bluetooth работает и определяется. Ошибки не исчезают с опытом — они просто умнеют |

Уже как то писал, что для Broadcom, чтобы работал Bluetooth, нужен, насколько помню, пропатченный модуль btusb и определенный firmware, иногда достаточно firmware, все зависит от устройства. Но есть и нюансы для некоторых чипов. Рекомендую проверить следующее 1. Перезагрузить модуль btusb и посмотреть вывод dmesg sudo modprobe -r btusb sudo modprobe -v btusb dmesg | egrep -i ‘blue|firm’ …… лучше смотреть сразу, запустив journalctl -f
2. Некоторые устройства не распознаются как Broadcom Bluetooth в lsusb, в этом случае для получения инфы нужно запустить Ошибки не исчезают с опытом — они просто умнеют |

Для информации, дублирую пост из этого топика
Проблема, думаю в другом, в основном для девайсов Broadcom в исходниках /linux-xxx/drivers/bluetooth/btusb.c отсутствуют VID:PID устройства. Как правило вносят изменения и пересобирают модуль btusb (лучше, конечно, использовать DKMS, чтобы каждый раз не пересобирать модуль при выходе нового ядра). Иногда бывает достаточно и одного firmware для данного устройства (выковыривают или из виндового драйвера или качают с github). Ошибки не исчезают с опытом — они просто умнеют |

Параллельно стоит windows 10. Там bluetooth работает |

Тогда остается то, что описал выше
Что нужно делать, описал выше. EDIT 1 — в принципе проверить и узнать VID:PID можно и подругому, используя команды, приведенные выше (которые ты игнорируешь и даже не стремишься что то выяснить) cat /sys/bus/usb/devices/3-1.6/id* Ошибки не исчезают с опытом — они просто умнеют |

Я думаю, это не порядок. |

У меня точно такое же сообщение
И это сообщение имеется у большинства и связано оно с отсутствием соответствующего firmware, который устанавливается вместе с пакетом crda Ошибки не исчезают с опытом — они просто умнеют |
