rt2800: validate step value for temperature compensation

2012-11-17T21:15:55+00:00

commit bf7e1abe434ba9e22e8dc04a4cba4ab504b788b8 upstream. Some hardware has correct (!= 0xff) value of tssi_bounds[4] in the EEPROM, but step is equal to 0xff. This results on ridiculous delta calculations and completely broke TX power settings.

rt2800usb: Added rx packet length validity check

2012-10-02T17:30:20+00:00

commit efd5d6b03bd9c9e0df646c56fb5f4f3e25e5c1ac upstream. On our system (ARM Cortex-M3 SOC running linux-2.6.33) frequent crashes were observed in the rt2800usb module because of the invalid length of the received packet (3392, 46920...). This patch adds the sanity check on the packet legth. Also, changed WARNING to ERROR in rt2x00lib_rxdone() so that the bad packet condition would be noticed. The fix was tested on the latest compat-wireless-3.5.1-1-snpc. Signed-off-by: Sergei Poselenov Acked-by: Ivo van Doorn Signed-off-by: John W. Linville Signed-off-by: Greg Kroah-Hartman

rt2x00: Fix rfkill polling prior to interface start.

2012-10-02T17:30:12+00:00

commit a396e10019eaf3809b0219c966865aaafec12630 upstream. We need to program the rfkill switch GPIO pin direction to input at device initialization time, not only when the interface is brought up. Doing this only when the interface is brought up could lead to rfkill detecting the switch is turned on erroneously and inability to create the interface and bringing it up.

rt61pci: fix NULL pointer dereference in config_lna_gain

2012-08-15T15:10:34+00:00

commit deee0214def5d8a32b8112f11d9c2b1696e9c0cb upstream. We can not pass NULL libconf->conf->channel to rt61pci_config() as it is dereferenced unconditionally in rt61pci_config_lna_gain() subroutine.

rt2x00usb: fix indexes ordering on RX queue kick

2012-07-19T15:58:56+00:00

commit efd821182cec8c92babef6e00a95066d3252fda4 upstream. On rt2x00_dmastart() we increase index specified by Q_INDEX and on rt2x00_dmadone() we increase index specified by Q_INDEX_DONE. So entries between Q_INDEX_DONE and Q_INDEX are those we currently process in the hardware. Entries between Q_INDEX and Q_INDEX_DONE are those we can submit to the hardware. According to that fix rt2x00usb_kick_queue(), as we need to submit RX entries that are not processed by the hardware. It worked before only for empty queue, otherwise was broken. Note that for TX queues indexes ordering are ok. We need to kick entries that have filled skb, but was not submitted to the hardware, i.e. started from Q_INDEX_DONE and have ENTRY_DATA_PENDING bit set. From practical standpoint this fixes RX queue stall, usually reproducible in AP mode, like for example reported here: https://bugzilla.redhat.com/show_bug.cgi?id=828824 Reported-and-tested-by: Franco Miceli Reported-and-tested-by: Tom Horsley Signed-off-by: Stanislaw Gruszka Signed-off-by: John W.
