* nl80211: fix monitor flagsJohannes Berg2008-10-311-1/+1
| | | | | | | | | | | | | NLA_NESTED attributes cannot be empty, but we want to be able to specify "no flags" (empty attribute) vs. "no change" (no attribute). Therefore, remove the NLA_NESTED policy so it can work as an empty attribute. I guess I should have used a u32 for these flags instead, but we're stuck with it now. Haven't noticed earlier because of a bug in iw... Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | We have to be careful if multiple "control frames" are passed in a very short intervals to the device's firmware. As p54_assign_address always put them into same memory location. To guarantee that this won't happen anymore, we have to treat control frames like normal data frames in the devices own memory management.

* airo: Kill directly reference of netdev->privWang Chen2008-10-311-85/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We have some reasons to kill netdev->priv: 1. netdev->priv is equal to netdev_priv(). 2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously netdev_priv() is more flexible than netdev->priv. But we cann't kill netdev->priv, because so many drivers reference to it directly. OK, becasue Dave S. Miller said, "every direct netdev->priv usage is a bug", and I want to kill netdev->priv later, I decided to convert all the direct reference of netdev->priv first. In this driver, I don't simply use netdev_priv() to replace netdev->priv. The reason is: Pointer netdev->priv was changed in this driver, but it shouldn't. Because the memory was allocated when alloc_netdev() and netdev->priv should always point to that memory. So I use netdev->ml_priv to replace netdev->priv. After replacing, both ai and ai->wifidev->ml_priv point to the same memory. Signed-off-by: Wang Chen <wangchen@cn.fujitsu.com> Cc: John W.

* rtl8187: add short slot handling for 8187BHerton Ronaldo Krzesinski2008-10-312-12/+41
| | | | | | | | | | | | | | | | | | | | | | This change adds short slot handling for 8187B variant of rtl8187 chips. Some things to note about changes done: * Values used are chosen to met 802.11-2007 spec. This raised a question about SIFS value used with 8187L: 0x22 (34) doesn't match any spec value. For now just don't change 8187L, but is something to be looked at. * On 8187B, the location of EIFS register is at the same place as BRSR+1 of struct rtl818x_csr. Unfortunately there is no clean way to accomodate 8187B differences currently, just use address of BRSR+1 and comment about it. The same thing happens for Ack timeout register, that is on CARRIER_SENSE_COUNTER location of 8187L. The eifs and ack timeout values are in units of 4us. All these registers information was gathered from references being the vendor gpl driver and 8180 datasheet, unfortunately there is no information about this on 8187B datasheet. Also the ack timeout value was inspired by the same calculation as done on rt2x00. Signed-off-by: Herton Ronaldo Krzesinski <herton@mandriva.com.br> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The HT handling has the following deficiencies, which I've (partially) fixed: * it always uses the AP info even if there is no AP, hence has no chance of working as an AP * it pretends to be HW config, but really is per-BSS * channel sanity checking is left to the drivers * it generally lets the driver control too much HT enabling is still wrong with this patch if you have more than one virtual STA mode interface, but that never happens currently. Once WDS, IBSS or AP/VLAN gets HT capabilities, it will also be wrong, see the comment in ieee80211_enable_ht(). Additionally, this fixes a number of bugs: * mac80211: ieee80211_set_disassoc doesn't notify the driver any more since the refactoring * iwl-agn-rs: always uses the HT capabilities from the wrong stuff mac80211 gives it rather than the actual peer STA * ath9k: a number of bugs resulting from the broken HT API I'm not entirely happy with putting the HT capabilities into struct ieee80211_sta as restricted to our own HT TX capabilities, but I see no cleaner solution for now.

* rfkill: rate-limit rfkill-input workqueue usage (v3)Henrique de Moraes Holschuh2008-10-311-8/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Limit the number of "expensive" rfkill workqueue operations per second, in order to not hog system resources too much when faced with a rogue source of rfkill input events. The old rfkill-input code (before it was refactored) had such a limit in place. It used to drop new events that were past the rate limit. This behaviour was not implemented as an anti-DoS measure, but rather as an attempt to work around deficiencies in input device drivers which would issue multiple KEY_FOO events too soon for a given key FOO (i.e. ones that do not implement mechanical debouncing properly). However, we can't really expect such issues to be worked around by every input handler out there, and also by every userspace client of input devices. It is the input device driver's responsability to do debouncing instead of spamming the input layer with bogus events. The new limiter code is focused only on anti-DoS behaviour, and tries to not lose events (instead, it coalesces them when possible). The transmitters are updated once every 200ms, maximum. Care is taken not to delay a request to _enter_ rfkill transmitter Emergency Power Off (EPO) mode. If mistriggered (e.g. by a jiffies counter wrap), the code delays processing *once* by 200ms.

* rfkill: add master_switch_mode and EPO lock to rfkill and rfkill-inputHenrique de Moraes Holschuh2008-10-314-87/+287
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add of software-based sanity to rfkill and rfkill-input so that it can reproduce what hardware-based EPO switches do, blocking all transmitters and locking down any further attempts to unblock them until the switch is deactivated. rfkill-input is responsible for issuing the EPO control requests, like before. While an rfkill EPO is active, all transmitters are locked to one of the BLOCKED states and all attempts to change that through the rfkill API (userspace and kernel) will be either ignored or return -EPERM errors. The lock will be released upon receipt of EV_SW SW_RFKILL_ALL ON by rfkill-input, or should modular rfkill-input be unloaded. This makes rfkill and rfkill-input extend the operation of an existing wireless master kill switch to all wireless devices in the system, even those that are not under hardware or firmware control. Since the above is the expected operational behavior for the master rfkill switch, the EPO lock functionality is not optional. Also, extend rfkill-input to allow for three different behaviors when it receives an EV_SW SW_RFKILL_ALL ON input event. The user can set which behavior he wants through the master_switch_mode parameter: master_switch_mode = 0: EV_SW SW_RFKILL_ALL ON just unlocks rfkill controller state changes (so that the rfkill userspace and kernel APIs can now be used to change rfkill controller states again), but doesn't change any of their states (so they will all remain blocked). This is the safest mode of operation, as it requires explicit operator action to re-enable a transmitter. master_switch_mode = 1: EV_SW SW_RFKILL_ALL ON causes rfkill-input to attempt to restore the system to the state before the last EV_SW SW_RFKILL_ALL OFF event, or to the default global states if no EV_SW SW_RFKILL_ALL OFF ever happened. This is the recommended mode of operation for laptops. master_switch_mode = 2: tries to unblock all rfkill controllers (i.e. enable all transmitters) when an EV_SW SW_RFKILL_ALL ON event is received. This is the default mode of operation, as it mimics the previous behavior of rfkill-input. In order to implement these features in a clean way, the entire event handling of rfkill-input was refactored into a single worker function. Protection against input event DoS (repeatedly firing rfkill events for rfkill-input to process) was removed during the code refactoring. It will be added back in a future patch. Note that with these changes, rfkill-input doesn't need to explicitly handle any radio types for which KEY_<radio type> or SW_<radio type> events do not exist yet. Code to handle EV_SW SW_{WLAN,WWAN,BLUETOOTH,WIMAX,...} was added as it might be needed in the future (and its implementation is not that obvious), but is currently #ifdef'd out to avoid wasting resources.

| | | | | | | | | | | | This patch was made on behalf of Johannes request. "mac80211 and IEEE80211_CONF_SHORT_SLOT_TIME" Of course, bss_info_changed provides some more useful data. e.g.: basic_rates, dtim_period, beacon_int and maybe even more. Everything can be hooked up if it's necessary. Signed-off-by: Christian Lamparter <chunkeey@web.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
