Description Andrew Cowie 2008-11-08 03:37:29 UTC
Upgraded from gentoo-sources 2.6.26 to 2.6.27-r2 yesterday. Discovered that kernel module "iwl4965" is no longer, replaced by new module "iwlagn". Ok, sure, whatever, but now using NetworkManager & `nm-applet` don't work, because networkmanager now thinks it is a wired device!

`iwconfig` and things like `iwlist wlan0 scan` work fine.

Dig, dig... and talking with johnny in #gentoo-desktop, he guessed it might be a HAL problem. Sure enough, `hal-device` shows it to be 802.3, not 802.11. I manually upgraded app-misc/hal-info to 20081022 on the guess that maybe the data there is wrong. Didn't help. As you'll see, this is NOT the signature of a wireless device!

Obviously I could downgrade to a 2.6.26 kernel, but that's not really solving the problem. I don't think it's a kernel bug, per se, but the fact the driver changed is obviously suspect.

Comment 1 Wormo (RETIRED) gentoo-dev 2008-11-09 07:07:42 UTC
I bet the new driver uses phy80211 and needs this HAL patch (not yet in a released version):
Comment 2 Andrew Cowie 2008-11-10 03:47:57 UTC
Hm. I gave it a go, but as is, that patch doesn't cleanly apply against the 0.5.11 that's in our tree, which is a shame. Someone a bit closer to this code is going to have to figure out how to backport it. Wish I could have done better here, sorry.

Comment 3 Robert Piasek (RETIRED) gentoo-dev 2008-11-13 13:35:52 UTC
Hmm.. Interesting. I don't have such problem on ANY of my machines with 4965

Comment 4 Andrew Cowie 2008-11-14 10:37:44 UTC
The only divergence on my system was udev; I upgraded that; no change.

Comment 5 Ricardo Salveti 2008-11-25 00:46:17 UTC
Got the same problem here but with a different hardware.

After I upgraded to 2.6.27-r3 and started using the new ath9k module for my Atheros AR5418, hal started to think that my ath0 interface is wired one:

Comment 6 Andrew Cowie 2008-11-25 01:23:17 UTC
Wow. Same problem as mine, but on a *different* driver. Yikes. So maybe it's not in the kernel? (Or, alternately, some common kernel subsystem has changed the way it reports information, and that's what is tricking out HAL).

Incidentally, for people without much hands-on knowledge, to get a wireless connection (assuming you are able to skip encryption and know an SSID to use),

# modprobe iwlagn
# ifconfig wlan0 up
# iwconfig wlan0 essid "$insert_ssid_here"
# dhcp -L wlan0

and while this "works" it is a right royal pain. I hope someone can figure out what the underlying problem is.

hal wireless extension fix

Hal fix to identify when a device has wireless extension.

Patch based on:

After applying the patch hal is able to identify the ath0 device as a wireless one:
udi = '/org/freedesktop/Hal/devices/net_00_1c_b3_c5_35_73'
  info.capabilities = {'net', 'net.80211'} (string list)

  net.linux.ifindex = 6  (0x6)  (int)
  net.originating_device = '/org/freedesktop/Hal/devices/pci_168c_24'  (string)

And, network manager started to work again :-)
Comment 8 Ricardo Salveti 2008-11-25 02:30:29 UTC
Sorry, I forgot to mention that the patch is for hal-0.5.11-r4.
Comment 9 Andrew Cowie 2008-11-25 03:23:40 UTC

I added your patch to a local sys-apps/hal-0.5.11-r4 (just added an epatch line to apply it) and emerged it. Restarted hald, and then loaded the iwlagn module. Success!

# lshal
udi = '/org/freedesktop/Hal/devices/net_00_13_e8_14_d1_f1_0'
  info.capabilities = {'net', 'net.80211'} (string list)
  info.category = 'net.80211'  (string)
  info.parent = '/org/freedesktop/Hal/devices/pci_8086_4229'  (string)
  info.product = 'WLAN Interface'  (string)
  info.subsystem = 'net'  (string)
  info.udi = '/org/freedesktop/Hal/devices/net_00_13_e8_14_d1_f1_0'  (string)
  linux.hotplug_type = 2  (0x2)  (int)
  linux.subsystem = 'net'  (string)
  linux.sysfs_path = '/sys/devices/pci0000:00/0000:00:1c.1/0000:03:00.0/net/wlan0'  (
  net.80211.mac_address = 85498057201  (0x13e814d1f1)  (uint64)
  net.address = '00:13:e8:14:d1:f1'  (string)
  net.arp_proto_hw_id = 1  (0x1)  (int)
  net.interface = 'wlan0'  (string)
  net.linux.ifindex = 9  (0x9)  (int)
  net.originating_device = '/org/freedesktop/Hal/devices/pci_8086_4229'  (string)

and so indeed NetworkManager now sees the device as a wireless one and does the right thing from there.

Gentoo package maintainers: recommend adding patch at comment #7 to sys-apps/hal and bumping to hal-0.5.11-r5.

Ricardo, I owe you a beer.

Comment 10 Tommaso Pasini 2008-12-12 16:14:50 UTC
The patch fixes the problem also with iwl3945. Nice job!
Comment 11 Ricardo Salveti 2008-12-15 00:13:23 UTC
Saleem, do you need any other additional information before adding this patch to gentoo?

Is there anything else we could do?

Comment 12 Pawel Madej aka Nysander 2008-12-31 20:57:30 UTC
is this patch applied?
Comment 13 Ricardo Salveti 2009-01-01 16:53:01 UTC
(In reply to comment #12)
> is this patch applied?

Nops, not yet

Comment 14 Ryan 2009-01-01 18:01:07 UTC
This was a problem for me also, using iwl3945, 2.6.28 and hal-0.5.11-r4. Not sure when this occured as I just switch to NetworkManager.

The patch in comment #7 fixed it for me.

The Patch fixed it for me to.
Comment 16 Andy Getz 2009-01-07 18:00:14 UTC
Patch in #7 fixed this issue for me on two systems, one x86 one amd64, both running tuxonice-sources-2.6.28, iwl3945, hal-0.5.11-r5, and networkmanager-0.7.0.
Thanks for the good patch work Ricardo!

Thanks, patching hal 0.5.11-r1 with attachment #173293 [details, diff] also fixes the problem for me!

Confirmed problem on kernel 2.6.28-gentoo, with ath5k driver, and HAL 0.5.11-r6.
Also confirming that the patch in Comment #7 fixes this problem.

Also want to confirm this solves this nasty "oops, where did my WLAN interface go?" error for the b43 driver and Networkmanager under 2.6.28.

I confirm that attachment #173293 [details, diff] fixes the same problem (wlan0 recognized as 802.3) for hal-0.5.11-r6, gentoo-sources-2.6.28 (the rt61pci module) and networkmanager-0.6.6.

Sorry guys, I think this got overlooked due to the very long subject line. Let me fix that and reassign so it at least gets looked at. If -r6 didn't fix it, it's very unlikely that -r7 will. (But please do upgrade anyway)
Comment 22 Christian Schmitt 2009-02-04 19:56:27 UTC
-r7 did not fix it. Patch still needed with hal-0.5.11-r7 and hal-info-20090202. Please apply in -r8!
