What: old static regulatory information and ieee80211_regdom module parameter
When: 2.6.29
Why: The old regulatory infrastructure has been replaced with a new one
which does not require statically defined regulatory domains. We do
not want to keep static regulatory domains in the kernel due to the
the dynamic nature of regulatory law and localization. We kept around
the old static definitions for the regulatory domains of:
* US
* JP
* EU
and used by default the US when CONFIG_WIRELESS_OLD_REGULATORY was
set. We also kept around the ieee80211_regdom module parameter in case
some applications were relying on it. Changing regulatory domains
can now be done instead by using nl80211, as is done with iw.
Who: Luis R. Rodriguez <lrodriguez@atheros.com>
---------------------------
What: dev->power.power_state
When: July 2007
Why: Broken design for runtime control over driver power states, confusing

Linux wireless regulatory documentation
---------------------------------------
This document gives a brief review over how the Linux wireless
regulatory infrastructure works.
More up to date information can be obtained at the project's web page:
http://wireless.kernel.org/en/developers/Regulatory
Keeping regulatory domains in userspace
---------------------------------------
Due to the dynamic nature of regulatory domains we keep them
in userspace and provide a framework for userspace to upload
to the kernel one regulatory domain to be used as the central
core regulatory domain all wireless devices should adhere to.
How to get regulatory domains to the kernel
-------------------------------------------
Userspace gets a regulatory domain in the kernel by having
a userspace agent build it and send it via nl80211. Only
expected regulatory domains will be respected by the kernel.
A currently available userspace agent which can accomplish this
is CRDA - central regulatory domain agent. Its documented here:
http://wireless.kernel.org/en/developers/Regulatory/CRDA
Essentially the kernel will send a udev event when it knows
it needs a new regulatory domain. A udev rule can be put in place
to trigger crda to send the respective regulatory domain for a
specific ISO/IEC 3166 alpha2.
Below is an example udev rule which can be used:
# Example file, should be put in /etc/udev/rules.d/regulatory.rules
KERNEL=="regulatory*", ACTION=="change", SUBSYSTEM=="platform", RUN+="/sbin/crda"
The alpha2 is passed as an environment variable under the variable COUNTRY.
Who asks for regulatory domains?
--------------------------------
* Users
Users can use iw:
http://wireless.kernel.org/en/users/Documentation/iw
An example:
# set regulatory domain to "Costa Rica"
iw reg set CR
This will request the kernel to set the regulatory domain to
the specificied alpha2. The kernel in turn will then ask userspace
to provide a regulatory domain for the alpha2 specified by the user
by sending a uevent.
* Wireless subsystems for Country Information elements
The kernel will send a uevent to inform userspace a new
regulatory domain is required. More on this to be added
as its integration is added.
* Drivers
If drivers determine they need a specific regulatory domain
set they can inform the wireless core using regulatory_hint().
They have two options -- they either provide an alpha2 so that
crda can provide back a regulatory domain for that country or
they can build their own regulatory domain based on internal
custom knowledge so the wireless core can respect it.
*Most* drivers will rely on the first mechanism of providing a
regulatory hint with an alpha2. For these drivers there is an additional
check that can be used to ensure compliance based on custom EEPROM
regulatory data. This additional check can be used by drivers by
registering on its struct wiphy a reg_notifier() callback. This notifier
is called when the core's regulatory domain has been changed. The driver
can use this to review the changes made and also review who made them
(driver, user, country IE) and determine what to allow based on its
internal EEPROM data. Devices drivers wishing to be capable of world
roaming should use this callback. More on world roaming will be
added to this document when its support is enabled.
Device drivers who provide their own built regulatory domain
do not need a callback as the channels registered by them are
the only ones that will be allowed and therefore *additional*
cannels cannot be enabled.
Example code - drivers hinting an alpha2:
------------------------------------------
This example comes from the zd1211rw device driver. You can start
by having a mapping of your device's EEPROM country/regulatory
domain value to to a specific alpha2 as follows:
static struct zd_reg_alpha2_map reg_alpha2_map[] = {
{ ZD_REGDOMAIN_FCC, "US" },
{ ZD_REGDOMAIN_IC, "CA" },
{ ZD_REGDOMAIN_ETSI, "DE" }, /* Generic ETSI, use most restrictive */
{ ZD_REGDOMAIN_JAPAN, "JP" },
{ ZD_REGDOMAIN_JAPAN_ADD, "JP" },
{ ZD_REGDOMAIN_SPAIN, "ES" },
{ ZD_REGDOMAIN_FRANCE, "FR" },
Then you can define a routine to map your read EEPROM value to an alpha2,
as follows:
static int zd_reg2alpha2(u8 regdomain, char *alpha2)
{
unsigned int i;
struct zd_reg_alpha2_map *reg_map;
for (i = 0; i < ARRAY_SIZE(reg_alpha2_map); i++) {
reg_map = &reg_alpha2_map[i];
if (regdomain == reg_map->reg) {
alpha2[0] = reg_map->alpha2[0];
alpha2[1] = reg_map->alpha2[1];
return 0;
}
}
return 1;
}
Lastly, you can then hint to the core of your discovered alpha2, if a match
was found. You need to do this after you have registered your wiphy. You
are expected to do this during initialization.
r = zd_reg2alpha2(mac->regdomain, alpha2);
if (!r)
regulatory_hint(hw->wiphy, alpha2, NULL);
Example code - drivers providing a built in regulatory domain:
--------------------------------------------------------------
If you have regulatory information you can obtain from your
driver and you *need* to use this we let you build a regulatory domain
structure and pass it to the wireless core. To do this you should
kmalloc() a structure big enough to hold your regulatory domain
structure and you should then fill it with your data. Finally you simply
call regulatory_hint() with the regulatory domain structure in it.
Bellow is a simple example, with a regulatory domain cached using the stack.
Your implementation may vary (read EEPROM cache instead, for example).
Example cache of some regulatory domain
struct ieee80211_regdomain mydriver_jp_regdom = {
.n_reg_rules = 3,
.alpha2 = "JP",
//.alpha2 = "99", /* If I have no alpha2 to map it to */
.reg_rules = {
/* IEEE 802.11b/g, channels 1..14 */
REG_RULE(2412-20, 2484+20, 40, 6, 20, 0),
/* IEEE 802.11a, channels 34..48 */
REG_RULE(5170-20, 5240+20, 40, 6, 20,
NL80211_RRF_PASSIVE_SCAN),
/* IEEE 802.11a, channels 52..64 */
REG_RULE(5260-20, 5320+20, 40, 6, 20,
NL80211_RRF_NO_IBSS |
NL80211_RRF_DFS),
}
};
Then in some part of your code after your wiphy has been registered:
int r;
struct ieee80211_regdomain *rd;
int size_of_regd;
int num_rules = mydriver_jp_regdom.n_reg_rules;
unsigned int i;
size_of_regd = sizeof(struct ieee80211_regdomain) +
(num_rules * sizeof(struct ieee80211_reg_rule));
rd = kzalloc(size_of_regd, GFP_KERNEL);
if (!rd)
return -ENOMEM;
memcpy(rd, &mydriver_jp_regdom, sizeof(struct ieee80211_regdomain));
for (i=0; i < num_rules; i++) {
memcpy(&rd->reg_rules[i], &mydriver_jp_regdom.reg_rules[i],
sizeof(struct ieee80211_reg_rule));
}
r = regulatory_hint(hw->wiphy, NULL, rd);
if (r) {
kfree(rd);
return r;
}

3.1 Guidelines for wireless device drivers
------------------------------------------
(in this text, rfkill->foo means the foo field of struct rfkill).
1. Each independent transmitter in a wireless device (usually there is only one
transmitter per device) should have a SINGLE rfkill class attached to it.
@ -363,10 +365,32 @@ This rule exists because users of the rfkill subsystem expect to get (and set,
when possible) the overall transmitter rfkill state, not of a particular rfkill
line.
5. During suspend, the rfkill class will attempt to soft-block the radio
through a call to rfkill->toggle_radio, and will try to restore its previous
state during resume. After a rfkill class is suspended, it will *not* call
rfkill->toggle_radio until it is resumed.
5. The wireless device driver MUST NOT leave the transmitter enabled during
suspend and hibernation unless:
5.1. The transmitter has to be enabled for some sort of functionality
like wake-on-wireless-packet or autonomous packed forwarding in a mesh
network, and that functionality is enabled for this suspend/hibernation
cycle.
AND
5.2. The device was not on a user-requested BLOCKED state before
the suspend (i.e. the driver must NOT unblock a device, not even
to support wake-on-wireless-packet or remain in the mesh).
In other words, there is absolutely no allowed scenario where a driver can
automatically take action to unblock a rfkill controller (obviously, this deals
with scenarios where soft-blocking or both soft and hard blocking is happening.
Scenarios where hardware rfkill lines are the only ones blocking the
transmitter are outside of this rule, since the wireless device driver does not
control its input hardware rfkill lines in the first place).
6. During resume, rfkill will try to restore its previous state.
7. After a rfkill class is suspended, it will *not* call rfkill->toggle_radio
until it is resumed.
