Patch (V2) to fix ifup-wireless

Since the original attachment was sent, the same problem was discovered to affect the ipw2100 and ipw2200 drivers. See http://forums.opensuse.org/english/get-help-here/wireless/443030-wireless-failing-start-thinkpad-x40.html.

V2 of the patch fixes this problem.

Thank you for the patch. I've forwarded it to the maintainer of sysconfig.

I've changed the default assignment slightly [2]. There is one convenient feature of wpa_supplicant. wpa_supplicant can handle more wlan drivers on the commandline (-Dnl80211,wext). If nl80211 is not available then wext is used. I've tested this feature with ipw2200 and it works. You can see messages in the wpa_supplicant.log [1].

-                WPA_DRIVER=nl80211
+                WPA_DRIVER=nl80211,wext

That is a good addition. Thanks for the attention to this problem.

scripts/ifup-wireless: WPA driver cleanup mt1

Larry,
thanks for your patches and bug report!!

Above is my current version of ifup-wireless script. I've applied your
attached patch and also sorted the drivers by driver and by name a bit...

I'd like to verify the nl80211 list before I commit it and we need a next
patch. It seems, there are some drivers that we didn't catched yet, e.g.
the adm8211 or mwl8 driver:

depmatch='^depends:.*mac80211'
for f in $(find /lib/modules/`uname -r`/kernel/drivers/net/wireless/ -name "*.ko") ; do b=$(echo $f | sed -e "s/.*\/net\/wireless\///g") ; /sbin/modinfo $f | grep -qs $depmatch && echo "$b" ; done | sort

adm8211.ko
at76c50x-usb.ko
ath/ar9170/ar9170usb.ko
ath/ath5k/ath5k.ko
ath/ath9k/ath9k.ko
b43/b43.ko
b43legacy/b43legacy.ko
iwlwifi/iwl3945.ko
iwlwifi/iwlagn.ko
iwlwifi/iwlcore.ko
libertas_tf/libertas_tf.ko
mac80211_hwsim.ko
mwl8k.ko
p54/p54common.ko
p54/p54pci.ko
p54/p54spi.ko
p54/p54usb.ko
rt2x00/rt2x00lib.ko
rt2x00/rt2x00pci.ko
rt2x00/rt2x00usb.ko
rtl818x/rtl8180.ko
rtl818x/rtl8187.ko

wl12xx/wl1251_sdio.ko
wl12xx/wl1251_spi.ko
wl12xx/wl1271.ko
zd1211rw/zd1211rw.ko

AFAIS not all drivers have a clear mac80211 dependency, e.g. has:
   rt61pci -> rt2x00lib -> mac80211

$ for m in rt61pci ; do echo -n "$m " ; /sbin/modinfo $m | grep -E "^depends:" ; done
rt61pci depends:        rt2x00lib,rt2x00pci,eeprom_93cx6,crc-itu-t
$ for m in rt2x00lib rt2x00pci eeprom_93cx6 crc-itu-t ; do echo -n "$m " ; /sbin/modinfo $m | grep -E "^depends:" ; done
rt2x00lib depends:        mac80211,led-class,cfg80211
rt2x00pci depends:        rt2x00lib,mac80211
eeprom_93cx6 depends:        
crc-itu-t depends:        

Vladimir should be back next week and we'll verify/complete the mapping
and go to release it then.

Adds adm8211,mwl8k,wl1251,wl1271 drivers to ifup-wireless.mt1

Adds adm8211,mwl8k,wl1251,wl1271 drivers to ifup-wireless.mt1 as described
in the comment above.

Script and patch look good. When new drivers are added, the "nl80211,wext" choice for unsupported will do the right thing. Only the bogus "WPA may not be supported" message will be output.

OK, thanks!
A notice is intentional here and I'd prefer to keep it. But we can change
it a bit, for example to "untested":


     if [ "$WPA_DRIVER" = "unsupported" ]; then
-        message "`printf "    %-9s warning: WPA configured but may be unsupported" $INTERFACE`"
-        message "`printf "    %-9s warning: by this device" $INTERFACE`"
-        info_mesg "using WPA drivers 'nl80211,wext' for interface $INTERFACE"
-        info_mesg "when you notice problems with this new driver, set " \
-                  "e.g. WIRELESS_WPA_DRIVER='wext' and file a bug report."
-        info_mesg "see also driver list in the /usr/sbin/wpa_supplicant -h output"
-        WPA_DRIVER="nl80211,wext"
+        message "`printf "    %-9s warning: WPA configured, but is untested" $INTERFACE`"
+        message "`printf "    %-9s warning: with this device" $INTERFACE`"
+        info_mesg "Using WPA drivers 'nl80211,wext' for interface $INTERFACE."
+        info_mesg "When you notice problems with the 'nl80211' driver, set "
+       info_mesg "e.g. WIRELESS_WPA_DRIVER='wext' and file a bug report."
+        info_mesg "See drivers list in the /usr/sbin/wpa_supplicant -h output"
+        WPA_DRIVER='nl80211,wext'

scripts/ifup-wireless: WPA driver cleanup mt2

Added textual changes from comment above, mapping for libertas*:
libertas*)         WPA_DRIVER=nl80211

and changed ndiswrapper to nl80211,wext -- "wext" only?
ndiswrapper|*.sys) WPA_DRIVER=nl80211,wext

The Windows drivers will have no knowledge of nl80211. They should be wext only as the nl80211 option will fail. We might as well save the time and the failure line.

I like the new wording regarding wext usage of wpa_supplicant as untested. In most cases it will work, and the user is less likely to be scared off by the message.

scripts/ifup-wireless: WPA driver cleanup mt3

Maps ndiswrapper to wext.

FYI: The patches are applied in git and to my current test package at:

http://download.opensuse.org/repositories/home:/mtomaschewski:/branches:/openSUSE:/11.3:/Update:/Test/openSUSE_11.3_Update_Test/

Vladimir,
please take a look and let me know / send patch when there is still
something.

I've added 2 more changes [2]. Only ath9k driver works with nl80211 [1] and Intel 4965 support was integrated into the iwlagn. I've also removed the ipw3945 duplicity.

Updated git patch for comment 14

Reverted ath5k change to wext:

/sbin/modinfo ath5k | grep depends
depends:        mac80211,led-class,cfg80211,ath

It works fine with nl80211 for me.

I've updated home:mtomaschewski:branches:openSUSE:11.3:Update:Test/sysconfig
and submitted it to openSUSE:11.3:Update:Test in request 45757. Changelog is:

-------------------------------------------------------------------
Wed Aug 18 12:13:26 UTC 2010 - mt@suse.de

- Fixed wireless hardware to wext/nl80211 WPA driver mapping.
  Changed to use -Dnl80211,wext by default for untested drivers
  to let the wpa_supplicant fallback to wext when nl80211 is not
  available. Adjusted info message about untested drivers and
  enabled untested driver handling also in case wpa_supplicant
  is not required but the user prefers to use it (bnc#623340,
  #623676,#624182,#625403,#631283). Thanks to all reporters,
  especially to Larry Finger and Vladimir Botka!

-------------------------------------------------------------------
Mon Jul 12 11:12:21 UTC 2010 - mt@suse.de

- Fixed check whether ipv6 is enabled or not in /sbin/ifup-dhcp to
  avoid dhcpv6 client start in case the interface is configured to
  start both, dhcpv4 and dhcpv6 clients (bnc#616765).

Update released for: sysconfig, sysconfig-debuginfo, sysconfig-debugsource
Products:
openSUSE 11.3 (debug, i586, x86_64)

*** Bug 604095 has been marked as a duplicate of this bug. ***

Hello,

Two questions
1) Update released for: sysconfig, sysconfig-debuginfo, sysconfig-debugsource
  What are exact version numbers for corresponding RPMs?

2) I also have problem with slow connection for Intel wireless adapter
  Speed is about 1Bmps in Linux, while it is 54Mbit in Windows.
OpenSUSE 11.3 has been updated (#zypper up) yesterday, 25.09.10
Should I file separate bug report, or I can submit details to this bug report?

Latest update from OpenSUSE 11.3 repository:
  sysconfig-0.73.7-2.1.1
Build date: 23 August 2010

It seems updates released on 2010-09-07 are still not available in repos.

They are. 2010-09-07 is the release / availability date of the package.
See also "rpm -q --changelog sysconfig" and comment 17.

There is always some time between the submit request, commit, build date
and the release, because all changes/updates are reviewed multiple times
by our autobuild, maintenance and qa teams.
The submit request is from 18.Aug, it has been reviewed and accepted [for Update:Test project] on 23.Aug. Then the packages are built&signed, go
into review again and when all is fine, they're released [moved to the
"Update" project] on 7.Sep.

See also "osc rq show 45757" output and comments 19 .. 22 + 25 above.
