* wireless: fix regression caused by regulatory config optionArjan van de Ven2008-10-26
| | | | | | | | | | | | | | | | | | | The default for the regulatory compatibility option is wrong; if you picked the default you ended up with a non-functional wifi system (at least I did on Fedora 9 with iwl4965). I don't think even the October 2008 releases of the various distros has the new userland so clearly the default is wrong, and also we can't just go about deleting this in 2.6.29... Change the default to "y" and also adjust the config text a little to reflect this.

* cfg80211: Add new wireless regulatory infrastructureLuis R. Rodriguez2008-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the new wireless regulatory infrastructure. The main motiviation behind this was to centralize regulatory code as each driver was implementing their own regulatory solution, and to replace the initial centralized code we have where: * only 3 regulatory domains are supported: US, JP and EU * regulatory domains can only be changed through module parameter * all rules were built statically in the kernel We now have support for regulatory domains for many countries and regulatory domains are now queried through a userspace agent through udev allowing distributions to update regulatory rules without updating the kernel. Each driver can regulatory_hint() a regulatory domain based on either their EEPROM mapped regulatory domain value to a respective ISO/IEC 3166-1 country code or pass an internally built regulatory domain. We also add support to let the user set the regulatory domain through userspace in case of faulty EEPROMs to further help compliance. Support for world roaming will be added soon for cards capable of this. For more information see: http://wireless.kernel.org/en/developers/Regulatory/CRDA For now we leave an option to enable the old module parameter, ieee80211_regdom, and to build the 3 old regdomains statically (US, JP and EU). This option is CONFIG_WIRELESS_OLD_REGULATORY. These old static definitions and the module parameter is being scheduled for removal for 2.6.29. Note that if you use this you won't make use of a world regulatory domain as its pointless. If you leave this option enabled and if CRDA is present and you use US or JP we will try to ask CRDA to update us a regulatory domain for us. Signed-off-by: Luis R.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is obviously good for userspace to know up front which interface modes a given piece of hardware might support (even if adding such an interface might fail later because of concurrency issues), so let's make cfg80211 aware of that. For good measure, disallow adding interfaces in all other modes so drivers don't forget to announce support for one mode when they add it.

* net/wireless/nl80211.c: fix endless Netlink callback loop.Julius Volz2008-07-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Although I only tested similar code (I don't use any of this wireless code), the state maintainance between Netlink dump callback invocations seems wrong here and should lead to an endless loop. There are also other examples in the same file which might have the same problem. Perhaps someone can actually test this (or refute my logic). Take the simple example with only one element in the list (which should fit into the message): 1. invocation: Start: idx = 0, start = 0 Loop: condition (++idx < start) => (1 < 0) => false => no continue, fill one entry, exit loop, return skb->len > 0 2. invocation: Start: idx = 0, start = 1 Loop: condition (++idx < start) => (1 < 1) => false => no continue, fill the same entry again, exit loop, return skb->len > 0 3. invocation: Same as 2. invocation, endless invocation of callback. Also, iterations where the filling of an element fails should not be counted as completed, so idx should not be incremented in this case.
