commit cb1b494663e037253337623bf1ef2df727883cb7 upstream. Make sure to check the number of endpoints to avoid dereferencing a NULL-pointer should a malicious device lack endpoints. Signed-off-by: Johan Hovold Signed-off-by: Dmitry Torokhov Signed-off-by: Ben Hutchings

Input: gtco - fix crash on detecting device without endpoints

2016-06-15T20:28:10+00:00

commit 162f98dea487206d9ab79fc12ed64700667a894d upstream. The gtco driver expects at least one valid endpoint. If given malicious descriptors that specify 0 for the number of endpoints, it will crash in the probe function. Ensure there is at least one endpoint on the interface before using it. Also let's fix a minor coding style issue. The full correct report of this issue can be found in the public Red Hat Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1283385 Reported-by: Ralf Spenneberg Signed-off-by: Vladis Dronov Signed-off-by: Dmitry Torokhov [bwh: Backported to 3.2: adjust context] Signed-off-by: Ben Hutchings

Input: aiptek - fix crash on detecting device without endpoints

2016-04-01T00:54:37+00:00

commit 8e20cf2bce122ce9262d6034ee5d5b76fbb92f96 upstream. The aiptek driver crashes in aiptek_probe() when a specially crafted USB device without endpoints is detected. This fix adds a check that the device has proper configuration expected by the driver. Also an error return value is changed to more matching one in one of the error paths.

Input: wacom - relax Bamboo stylus ID check

2012-05-30T23:43:48+00:00

commit c5981411f60c31f0dff6f0f98d2d3711384badaf upstream. Bit 0x02 always means tip versus eraser. Bit 0x01 is something related to version of stylus and different values are starting to be used. Relaxing proximity check is required to be used with 3rd generation Bamboo Pen and Touch tablets.

Input: wacom - correct max Y value on medium bamboos

2011-10-10T15:55:37+00:00

Medium size Bamboo P&T driver reused max X/Y form older Bamboo 1 medium size tablets and never updated to real value. Actual active area of tablet is slightly larger in Y direction. Signed-off-by: Chris Bagwell Acked-by: Ping Cheng Signed-off-by: Dmitry Torokhov

Input: wacom - add ABS_DISTANCE to Bamboo Pen reports

2011-10-10T15:55:34+00:00

Tablet reports a distance of 0 right at highest point possible to be in proximity and distance_max when touching tablet. Inverse the distance since user land has no way of knowing ABS_DISTANCE is not distance from tablet. Signed-off-by: Chris Bagwell Signed-off-by: Dmitry Torokhov

Input: wacom - remove unneeded touch pressure initialization

2011-10-10T15:55:30+00:00

These were left in during removal of touch pressure reports but not needed now. Signed-off-by: Chris Bagwell Reviewed-by: Ping Cheng Signed-off-by: Dmitry Torokhov
