rt2x00: Clear queue entry flags during initialization · 9c0ab712

Ivo van Doorn authored Jul 21, 2008

When the queues are being initialized the entry flags fields must be
reset to 0. When this does not happen some entries might still be
marked as "occupied" after an ifdown & ifup cycle which would trigger
errors when the entry is being accessed:

	phy0 -> rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the non-full queue 0.
	Please file bug report to http://rt2x00.serialmonkey.com.

This also fixes the mac80211 warning:

	------------[ cut here ]------------
	WARNING: at net/mac80211/tx.c:1238 ieee80211_master_start_xmit+0x30a/0x350 [mac80211]()

rt2x00: Force full register config after start() · 74c0ee9b

Ivo van Doorn authored Jul 21, 2008

rt2x00 will only perform configuration changes from
mac80211 when the configuration option has changed.
This means it keeps track of the current active configuration
and will check these values when the config() callback function
is used.

However this causes breakage when the interface has been
brought down and up again, since all stored active values
aren't reset while the registers might have.
This is for example the case with rt61pci antenna registers which
will jump to invalid values when the interface has been started.

To make sure a full configuration takes place after the start()
callback function, a new flag is added which will be checked
during config() and skips the "what's changed" phase.

rt2x00: Fix QOS sequence counting · 5adf6d63

Ivo van Doorn authored Jul 20, 2008

When IEEE80211_TX_CTL_ASSIGN_SEQ is not set,
the driver should disable hardware sequence counting
to make sure the mac80211 provided counter is used.
This fixes QOS sequence counting, since that is one
of the cases where mac80211 provides a seperate
sequence counter.

By moving the sequence counting code to rt2x00queue
we make sure that _all_ frames get the sequence counter,
including RTS/CTS and Beacon frames.

rt2x00: Fix the beacon length bug · b93ce437

Iwo Mergler authored Jul 19, 2008

When setting up a beacon template, the length of the beacon is
calculated with the assumption that the SKB already contains
the Tx descriptor. In the case of beacons it doesn't.

This patch undoes the damage by adding the Tx descriptor length
to the beacon length. This is safe, because the shortest possible
beacon is longer than the Tx header.

rt2x00: Fix EIFS timing value · f2fdbc48

Ivo van Doorn authored Jul 19, 2008

Olivier reported a difference between the EIFS
values used in the legacy driver and the one in
the rt2x00 drivers.

In rt2x00 the value was
	( SIFS + (8 * (IEEE80211_HEADER + ACK_SIZE)) )
which comes down to 314us while the legacy driver uses the value 364us

This was caused because EIFS is: SIFS + DIFS + AckTime
This patch will fix this by adding the DIFS by the above value,
and creating a SHORT_EIFS define which uses the SHORT_DIFS.

rfkill_mutex, which protects the global state, the list of registered

rfkill: fix led-trigger unregister order in error unwind · 37f55e9d

Henrique de Moraes Holschuh authored Jul 21, 2008

rfkill needs to unregister the led trigger AFTER a call to
rfkill_remove_switch(), otherwise it will not update the LED state,
possibly leaving it ON when it should be OFF.

To make led-trigger unregistering safer, guard against unregistering a
trigger twice, and also against issuing trigger events to a led trigger
that was unregistered.  This makes the error unwind paths more resilient.

Refer to "rfkill: Register LED triggers before registering switch".
