2008-07-29rt2x00: Large vendor requests for rt73usb firmware upload and beaconsIwo Mergler
Switches rt73usb to use large vendor requests for firmware and beacons. This also fixes the garbled beacon bug. Signed-off-by: Iwo Mergler <Iwo@call-direct.com.au> Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-07-29rt2x00: Support for large vendor requestsIwo Mergler
Adds an extra rt2x00 vendor request function to support register transfers beyond the CSR_CACHE_SIZE / USB packet size limit. This is useful for firmware uploads, beacon templates and keys, all of which are to large to do with a single USB request.

2008-07-29rt2x00: Fix EIFS timing valueIvo van Doorn
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.

2008-07-29ath5k: fix recursive locking in ath5k_beacon_updateBob Copeland

2008-07-29rfkill: mutex fixesHenrique de Moraes Holschuh
There are two mutexes in rfkill: rfkill->mutex, which protects some of the fields of a rfkill struct, and is also used for callback serialization. rfkill_mutex, which protects the global state, the list of registered rfkill structs and rfkill->claim. Make sure to use the correct mutex, and to not miss locking rfkill->mutex even when we already took rfkill_mutex.

2008-07-29rfkill: fix led-trigger unregister order in error unwindHenrique de Moraes Holschuh
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".

2008-07-29Ath5k: flush workJiri Slaby
Make sure that the irq is not in progress after stop. This means two things: - ensure the intr setting register is set by flushing posted values - call synchronize_irq() after that Also flush stop tx write, inform callers of the tx stop about still pending transfers (unsuccessful stop) and finally don't wait another 3ms in ath5k_rx_stop, since ath5k_hw_stop_rx_dma ensures transfer to be finished.

2008-07-29Ath5k: fix memory corruptionJiri Slaby
When signal is noisy, hardware can use all RX buffers and since the last entry in the list is self-linked, it overwrites the entry until we link new buffers. Ensure that we don't free this last one until we are 100% sure that it is not used by the hardware anymore to not cause memory curruption as can be seen below. This is done by checking next buffer in the list. Even after that we know that the hardware refetched the new link and proceeded further (the next buffer is ready) we can finally free the overwritten buffer. We discard it since the status in its descriptor is overwritten (OR-ed by new status) too. ============================================================================= BUG kmalloc-4096: Poison overwritten ----------------------------------------------------------------------------- INFO: 0xffff810067419060-0xffff810067419667.

Piss-poor sysctl registration API strikes again, film at 11... What we really need is _pathname_ required to be present in already registered table, so that kernel could warn about bad order. That's the next target for sysctl stuff (and generally saner and more explicit order of initialization of ipv[46] internals wouldn't hurt either). For the time being, here are full fixups required by ..._rotable() stuff; we make per-net sysctl sets descendents of "ro" one and make sure that sufficient skeleton is there before we start registering per-net sysctls.

2008-07-27[SCSI] extend the last_sector_bug flag to cover more sectorsAlan Jenkins
The last_sector_bug flag was added to work around a bug in certain usb cardreaders, where they would crash if a multiple sector read included the last sector. The original implementation avoids this by e.g. splitting an 8 sector read which includes the last sector into a 7 sector read, and a single sector read for the last sector. The flag is enabled for all USB devices. This revealed a second bug in other usb cardreaders, which crash when they get a multiple sector read which stops 1 sector short of the last sector. Affected hardware includes the Kingston "MobileLite" external USB cardreader and the internal USB cardreader on the Asus EeePC. Extend the last_sector_bug workaround to ensure that any access which touches the last 8 hardware sectors of the device is a single sector long. Requests are shrunk as necessary to meet this constraint. This gives us a safety margin against potential unknown or future bugs affecting multi-sector access to the end of the device. The two known bugs only affect the last 2 sectors. However, they suggest that these devices are prone to fencepost errors and that multi-sector access to the end of the device is not well tested. Popular OS's use multi-sector accesses, but they rarely read the last few sectors. Linux (with udev & vol_id) automatically reads sectors from the end of the device on insertion. It is assumed that single sector accesses are more thoroughly tested during development.

Minor cleanups for the MMC/SD support on avr32: - Make at32_add_device_mci() properly initialize "missing" platform data ... so boards like STK1002 won't try GPIO 0. - Switch over to gpio_is_valid() instead of testing for only one designated value. - Provide STK1002 platform data for the unlikely case that switches are set so first Ethernet controller isn't in use. (That's the only way to get card detect and writeprotect switch sensing on the STK1000.) And get rid of one "unused variable" warning.
