* net: make dev_disable_lro use physical device if passed a vlan dev (v2)Neil Horman2011-05-251-0/+7
| | | | | | | | | | | If the device passed into dev_disable_lro is a vlan, then repoint the dev poniter so that we actually modify the underlying physical device.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a new generic gpio rfkill driver to support rfkill switches which are controlled by gpios. The driver also supports passing in data about the clock for the radio, so that when rfkill is blocking, it can disable the clock. This driver assumes platform data is passed from the board files to configure it for specific devices.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In ad-hoc mode, beacon timers are configured differently compared to AP mode, and (depending on the scenario) can vary enough to make the beacon tasklet not detect slot 0 based on the TSF. Since staggered beacons are not (and cannot be) used in ad-hoc mode, it makes more sense to just hardcode slot 0 here, avoiding unnecessary TSF reads and calculations.

| | * cfg80211: Use consistent BSS matching between scan and smeJouni Malinen2011-05-199-15/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cfg80211 scan code adds separate BSS entries if the same BSS shows up on multiple channels. However, sme implementation does not use the frequency when fetching the BSS entry. Fix this by adding channel information to cfg80211_roamed() and include it in cfg80211_get_bss() calls. Please note that drivers using cfg80211_roamed() need to be modified to fully implement this fix. This commit includes only minimal changes to avoid compilation issues; it maintains the old (broken) behavior for most drivers. ath6kl was the only one that I could test, so I updated it to provide the operating frequency in the roamed event.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The locking in mesh_{mpath,mpp}_table_grow not only has an rcu_read_unlock() missing, it's also racy (though really only technically since it's invoked from a single function only) since it obtains the new size of the table without any locking, so two invocations of the function could attempt the same resize. Additionally, it uses synchronize_rcu() which is rather expensive and can be avoided trivially here. Modify the functions to only use the table lock and use call_rcu() instead of synchronize_rcu().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mac80211 uses call_rcu() with functions that are defined in the module, so it must use rcu_barrier() at module exit time. Luckily, this seems to not be a problem in practice as module unload and unregistration takes a long time and probably does multiple synchronize_rcu().
