[PATCH 0/4] HID: logitech-hidpp: fixes for error conditions
From: Peter Wu
Date: Thu Dec 11 2014 - 07:51:42 EST
Here are four patches intended for the 3.19 stream and are based on
jikos/hid (for-next, v3.18-rc4-144-gd9372ee).
* The first is actually from Benjamin Tissoires, but modified to remove
a now unneeded goto.
* The second one depends on the first (it could work without, but there
will be a context mismatch).
* The third one can be applied independently of the others and is needed
to avoid a possible buffer overread.
* The fourth and final patch fixes an unbalanced hid_device_io_start().
Tested by booting with three paired USB devices (QEMU + USB
passthrough), two of them are powered off and one M525 is active. evbug
registers mouse events.
Peter Wu (4):
HID: logitech-hidpp: do not return the name length
HID: logitech-hidpp: check name retrieval return code
HID: logitech-hidpp: add boundary check for name retrieval
HID: logitech-hidpp: disable io in probe error path
