Bug 585802

I'd say it is an important enhancement, not major: the user can set the
WIRELESS_WPA_DRIVER='nl80211' variable ...

Tested on _11.2_ final with:

* ath5k: Netgear WG511T, PCMCIA
  Vendor: pci 0x168c "Atheros Communications Inc."
  Device: pci 0x0013 "Atheros AR5001X+ Wireless Network Adapter"
  SubVendor: pci 0x1385 "Netgear"
  SubDevice: pci 0x5b00 
  Driver: "ath5k"

  => nl80211 works fine

* iwlagn: On-Board wlan of a Dell Latitude E6500
  Vendor: pci 0x8086 "Intel Corporation"
  Device: pci 0x4232 "Wireless WiFi Link 5100"
  SubVendor: pci 0x8086 "Intel Corporation"
  SubDevice: pci 0x1321 "Wireless WiFi Link 5100"
  Driver: "iwlagn"

  => nl80211 works fine, even I get an error message:

       Failed to set interface wlan0 mode
       Could not configure driver to use managed mode

     Vladimir, could you retest bug 535750 comment 7?

btw: what about networkmanager, shouldn't that switch as well ?

IMO yes -- there is also a feature request for NM. I don't know the details.

Created attachment 348671 [details]
let NM set the wpa driver from environment

Maybe the attached patch for Networkmanager will do the trick?

No. This bug is about sysconfig, not really about NM. There is nobody,
that could/would set any variable for NM. NM does not read any ifcfg
files and this variable is not set by default.
=> NM has to decide itself how to deal with this issue.

In sysconfig this variable is a workaround for cases, when the user
wants to change the default (workaround for 11.2 for use nl80211).

I'll apply a patch for 11.3 that sets the nl80211 by default and the
user can override it with the old 'wext' using WIRELESS_WPA_DRIVER,
when nl80211 does not work for him and report a bug about...

NM is started from /etc/inid.d/network script, which reads the file
 /etc/sysconfig/network/config

One could check for the existence of WIRELESS_WPA_DRIVER over there and export it before starting NM like this.

[[ "x$WIRELESS_WPA_DRIVER" != "x" ]] && export WIRELESS_WPA_DRIVER
$FAKE startproc $NETWORKMANAGER_BIN



> => NM has to decide itself how to deal with this issue.

NM has "wext" simply hardcoded, it makes no decision at all.

Then it has to be fixed and make the decision somehow. Please
open a new bug report for NM and don't mix NM and ifup.

The network script starts it but it does not and will not export
sysconfig settings to NM. NM is not using any sysconfig settings
and we do not plan to change it - please do not mix NM and ifup.

Then I guess it has to be fixed -- please open a new bug report.

I have opened bug 591959.

Don't know if this my experience is this bug:
Since Milestone6 factory I cannot start wireless through traditional ifup:
Something like: "missing netlink module nl80211"

Changing back to NetworkManager (using yast2) : wireless connects without problem

The message says that the wlan driver is not able to use the new nl80211 extension yet. You can use the old wext extension. Set WIRELESS_WPA_DRIVER="wext" in /etc/sysconfig/network/config.

What wlan driver and wlan adapter do you use ? Could you post hwinfo --wlan ? Does setting wext work for you ?

Did find myself: "wext" for broadcom-sta-kmp-desktop
home:/computersalat:/KMP:/Update/openSUSE_Factory/

...also kernel-module nl80211.ko doesn't exist, which I searched for in the first place, but it is built-in compiled.

home:/computersalat:/KMP:/Update/openSUSE_Factory/ provides wl driver which works setting:
WIRELESS_WPA_DRIVER="wext" in /etc/sysconfig/network/config

Thanks! Applied your patch from sr 40602 to git, then to
Base:System/sysconfig. Goes to factory via sr #40636.

Thanks Ralph!

BTW: ifcfg-eth1 would be sufficient here.

bug 555850 is for 11.2, not 11.3.

factory is using the new driver already a while => fixed.
