Description samoht0 2016-05-20 18:59:55 UTC 
Description of problem:

Wifi hard blocked by rfkill on ath9k/hp_wmi kernel modules.

Version-Release number of selected component (if applicable):

4.4.10-200.fc22.x86_64
longtime bug, see https://bugzilla.redhat.com/show_bug.cgi?id=954070

How reproducible:

Always.

Steps to Reproduce:

1.
Boot system. Wifi soft and hardware switch off.

2.
# rfkill list
0: hp-wifi: Wireless LAN
        Soft blocked: yes
        Hard blocked: yes
...
3: phy0: Wireless LAN
        Soft blocked: yes
        Hard blocked: yes

3.
Remove soft block and activate wifi hardware switch.

# rfkill list
0: hp-wifi: Wireless LAN
        Soft blocked: no
        Hard blocked: no
...
3: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: yes

Wifi don't work.

4.
Use /etc/modprobe.d/hp.conf to blacklist hp_wmi

5.
Reboot system. Wifi soft and hardware switch off.

6.
# rfkill list
0: phy0: Wireless LAN
        Soft blocked: yes
        Hard blocked: yes
[no hp-wifi]

7.
Remove soft block and activate wifi hardware switch. 

# rfkill list
0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no
[no hp-wifi]

Wifi works.


Actual results:

Wifi blocked and hp_wmi need's to be blacklisted to use wifi.

Expected results:

Wifi working out of box.

Additional info:

Locks like this patch for hp_wmi fixed the issue for the testers, but didn't make it into mainline since March.

https://bugzilla.kernel.org/show_bug.cgi?id=69131#c13

F23 and F24 should be affected too.

Comment 3 Laura Abbott 2016-05-23 14:28:48 UTC 
That patch does not have a Signed-off-by so it cannot be pulled into the Fedora tree. The patch author also needs to at least submit to a mailing list and have it reviewed by the maintainer.
Comment 4 samoht0 2016-05-23 16:48:19 UTC 
To be honest, this is a little bit disappointing.
But well, if the patch isn't suitable, there's no need to keep the report open. Blacklisting hp_wmi is fine by me.
Comment 5 Laura Abbott 2016-05-23 20:18:25 UTC 
The technical content of the patch is fine. If it had a Signed-off-by I could consider bringing it. The Signed-off-by is a legal requirement and I don't have any flexibility there. If you can get the patch author to submit an actual patch with a Signed-off-by we can re-evaluate.

Laura, the patch is now signed off by its author, and has been submitted to the kernel subsystem mailing list for review by maintainer and others:

http://permalink.gmane.org/gmane.linux.drivers.platform.x86.devel/9288

Please revert the status of this bug to NEW so this will still be tracked. Thanks.
Comment 7 Laura Abbott 2016-06-13 21:17:00 UTC 
Yay! I've changed the status of the bug so it can be tracked again. I'm going to wait a few days to see if the maintainer has any comments before I bring it in.

Thanks for bringing this to my attention.

Comment 11 David Ward 2016-06-26 13:20:38 UTC 
To make the errata more helpful, I would suggest updating the title of this bug — given both the content of the kernel patch, as well as the upstream bug report which shows a wider range of HP laptops affected by the same issue and addressed with this fix.

From these, we can see that:
 * the wireless chipset is not relevant (ath9k),
 * the issue is known to affect several different models of HP laptops believed to all be manufactured during a certain time period (before 2009), and
 * the rfkill settings that are impacted by this fix include not just Wi-Fi ('hp-wifi') but also Bluetooth ('hp-bluetooth'), WWAN ('hp-wwan'), and GPS ('hp-gps')

Perhaps the bug title should be closer to the following:
"rfkill is hard blocked on pre-2009 HP laptops"

I didn't test the patch yet, since kernel-4.4.14-200.fc22 hasn't been pushed testing so far.

But I agree, this isn't a ath9k issue and dont't impact hp-wifi only. Especially on HP 635 bluetooth is not blocked and are no other hp-xxx devices present. But this seems to differ between the HP models.

I don't agree with "pre-2009". The HP 635 was introduced as low-end series in late summer 2011. See review from September 2011:
http://www.notebookcheck.net/Review-HP-635-LH416EA-ABD-Notebook.61035.0.html

I bought my laptop in September 2012. I've got the model which came with the later AMD E-450 APU and SUSE LED preinstalled.

Comment 15 samoht0 2016-06-27 05:26:24 UTC 
With kernel-4.4.14-200.fc22 still the same here. phy0 stays blocked as described in the report. There are two radio killswitches as before:

localhost NetworkManager[650]: <info>  rfkill2: found WiFi radio killswitch (at /sys/devices/platform/hp-wmi/rfkill/rfkill2 (platform driver hp-wmi)
localhost NetworkManager[650]: <info>  rfkill1: found WiFi radio killswitch (at /sys/devices/pci0000:00/0000:00:15.3/0000:0 (driver ath9k)

Maybe the upstream bug/patch and my issue are actually different.

I would agree with that — as I said, this patch is known to fix HP laptops manufactured in a certain time period before 2009, and your system is much newer than that. Since a fix has been pushed already for the earlier laptops, perhaps the title of this bug could be updated as I suggested, and then you could open a new bug in Fedora for your issue?

I think you may actually be affected by this other upstream kernel bug instead, which was reported for the HP 635:
https://bugzilla.kernel.org/show_bug.cgi?id=42898

Yes, sure. Changing the tile to fit the pushed fix avoids confusion.

Upstream kernel bug #42898 shows exactly the same symptoms. I will look, if I can dig out some helpful extra information, and if so, I'll file a new bug in Fedora (after installing F24).

Comment 24 samoht0 2016-07-31 15:02:21 UTC 
As David Ward suggested, I filed my updated Information into upstream kernel bug #42898, which fits my HP 635 and the typical symptoms:

https://bugzilla.kernel.org/show_bug.cgi?id=42898#c8

I truly hope, this will get more attention by upstream than in the last 4 1/2 years. I (currently) didn't file a new bug in Fedora's bugzilla, since there is no proposed fix.

With pre-2009 HP laptops fixed this bug keeps closed.
