Priority Requester: Mandatory Projectmanager: Important - openSUSE-11.4: New + openSUSE-11.4: Rejected by Karl Cheng (qantas94heavy) + reject reason: Not done in time for openSUSE 11.4. Priority Requester: Mandatory + openSUSE Distribution: New + Priority + Requester: Desirable Requested by: Vladimir Botka (vbotka) Developer: Vladimir Botka (vbotka) Partner organization: openSUSE.org Description: The regulatroy domain handling for wireless cards was done by each driver seperately before mac80211/cfg80211. cfg80211 is used to unify the handling of regulatory domains for wireless devices. However cfg80211 depends on the user space configuring the regulatory domain. A user space daemon is currently developed (see [1]). It basically provides the allowed channels for all known regulatory domains. Additionally it would be nice to allow the configuration of the regulatory domain from the Yast network module.

A command line tool for setting the domain is already available (iw) but needs to be updated. #3: Helmut Schaa (hschaa) (2009-02-09 16:09:28) (reply to #2) Just submitted an update for Factory. #4: Helmut Schaa (hschaa) (2009-02-10 10:59:40) (reply to #2) wpa_supplicant 0.6.7 already has support for setting the regulatory domain. We'll get that with the next version update. #5: Helmut Schaa (hschaa) (2009-02-10 13:40:25) (reply to #2) iw, crda and wireless-regdb are part of factory now #6: Kshitij Kulshreshtha (polyconvex) (2009-03-25 11:53:33) Sometimes on a short visit abroad a user might not bother to update their timezone information on their laptop but still want to use a wireless network. In this case setting the regulatory domain based on timezone is not the right thing to do. Why not let the networkmanager applet ask the user himself to provide the country as a part of the dialog to setup the network? (A map similar to the yast timezone selector built into KNetworkManager?) #7: Marius Tomaschewski (mtomaschewski) (2009-06-08 11:27:49) We've already another enhancement bugs for sysconfig/wireless... so let's just add it for 11.2. Helmut, let's speak in the next days about the requirements on the sysconfig side (I guess it is just one optional variable) and add this together with the another enhancements. Michal (yast2 network) requires the sysconfig support to implement it on the yast2 side. #11: Marius Tomaschewski (mtomaschewski) (2009-09-08 15:56:43) (reply to #9) Let's define the sysconfig ifcfg -file variable as: WIRELESS_REGULATORY_DOMAIN='00' The '00' value is the ISO / IEC 3166 alpha2 country code as used in the regdb / wpa_supplicant / iw tool. The _sysconfig_ default is '' , that is empty string. #12: Marius Tomaschewski (mtomaschewski) (2009-09-08 16:39:46) (reply to #11) Hmm... it looks like the reg domain is a global and not a per-interface setting, in iw: reg set <ISO/IEC 3166-1 alpha2> reg get this means it has to go to network/config and not into ifcfg file. Is this correct? #15: Jiri Benc (jbenc) (2009-09-09 13:23:09) (reply to #12) Yes, this is a system-wide setting. On purpose, you don't usually have you computer in two different regulatory zones ;-) I don't see what's the problem with using the timezone setting, though. Yes, it would require a translation table (to map e.g. Europe/Prague to CZ), but other than that, it should provide all the information we need: in what country we are located. #16: Marius Tomaschewski (mtomaschewski) (2009-09-09 13:53:06) (reply to #15) OK, thanks for verifying this! I don't have any problem when yast2 is setting the WIRELESS_REGULATORY_DOMAIN='CZ' value based on the TIMEZONE='Europe/Prague' setting by default / as preselection. But I need the correct, valid and final value for the utilities and don't want to provide any translation table and waste e.g. boot time in sysconfig. It also makes sense to check that the alpha-2 code is in the wireless-regdb and perhaps propose an another value if possible or reject & reset it -- in sysconfig it is too late to do this or ask the user what to do. The package implementing this is in Base:System/sysconfig project and goes to factory today. When iw reg set is used, the value is applied correctly to the crda/kernel. When it is set via wpa_supplicant config, there is no attempt to set it visible in udev -- seems to be a wpa_supplicant bug -> bugzilla. #17: Jiri Benc (jbenc) (2009-09-09 14:01:13) (reply to #16) Yes, all of that makes sense to me. #18: Vladimir Botka (vbotka) (2009-09-09 20:34:24) (reply to #16) Part of the project http://linuxwireless.org/en/developers/Documentation/nl80211 is also an wpa_supplicant with -Dnl80211 which will solves this problem. The yast module can set both the WIRELESS_REGULATORY_DOMAIN in sysconfig and country= in wpa_supplicant.conf. #20: Marius Tomaschewski (mtomaschewski) (2009-09-09 22:40:21) (reply to #18) Stop :-) sysconfg / ifup is not using /etc/.../wpa_supplicant.conf -- it generates one per interface from network/config and network/ifcfg* settings. So just set the WIRELESS_REGULATORY_DOMAIN, ifup-wireless will add the (expanded) "country=$WIRELESS_REGULATORY_DOMAIN" statement to the generated wpa_supplicant config. #19: Vladimir Botka (vbotka) (2009-09-09 21:34:26) (reply to #16) The new nl80211 extension is already available in Factory. # wpa_supplicant -c /etc/wpa_supplicant/wpa_supplicant.conf -i wlan0 -dd - Dnl80211 Initializing interface 'wlan0' conf '/etc/wpa_supplicant/wpa_supplicant.conf' driver 'nl80211' ctrl_interface 'N/A' bridge 'N/A' Configuration file '/etc/wpa_supplicant/wpa_supplicant.conf' -> '/etc/wpa_supplicant/wpa_supplicant.conf' Reading configuration file '/etc/wpa_supplicant/wpa_supplicant.conf' country='CZ' #21: Marius Tomaschewski (mtomaschewski) (2009-09-09 22:42:34) (reply to #19) Yes I know already about the new driver. Question is if we can switch to use this driver already. Let's continue with the driver details in bugzilla. #22: Marius Tomaschewski (mtomaschewski) (2009-10-02 08:52:57) FYI: The sysconfig-0.72.4 version in openSUSE:Factory / 11.2 implements this feature. It provides the WIRELESS_REGULATORY_DOMAIN variable and adds it to the per-interface wpa_supplicant.conf as well as sets it via iw command in case of old (iwconfig) setup. It does not change to the new nl80211 driver (or another one supporting it) by default, the user has to set WIRELESS_WPA_DRIVER="nl80211" per interface or wpa_supplicant will ignore it. #25: Jiri Benc (jbenc) (2009-11-04 11:56:30) Opening for 11.3 and setting as mandatory for requester, as without the feature wifi cards are not fully usable outside of the US (and in some cases not even there). #26: Marius Tomaschewski (mtomaschewski) (2010-03-05 15:07:43) (reply to #25) Thanks! I've created bug 585802 to switch to the new nl80211 wpa_supplicant driver as default in ifup-wireless, except in cases where we know that it does not work. #27: Vladimir Botka (vbotka) (2010-05-18 20:22:08) crda and wireless-regdb packages are available and functional in 11.3 . New nl80211 extension must be used to set the country. #34: Marius Tomaschewski (mtomaschewski) (2011-05-19 14:58:40) Sysconfig package is in submit request 12203 (https://build.suse.de/request/show/12203) on the way to SLE-11-SP2:GA #35: Vladimir Botka (vbotka) (2011-06-20 12:05:29) wireless-regdb submitted to SUSE:SLE-11-SP2:GA with SRID 12958. It was submitted with SRID 12417 in week 22, but was rejected with the comment "/mounts/work_src_done/SLE11-SP2/wireless-regdb was not checked in by bg for the following reasons: (submitrequest 12417 on https://build.suse.de) please fix conflict marker in changelog.
