usbcore: Fix wrong device in an error message in hub_port_connect() 2014-09-05T23:36:42+00:00 Takashi Iwai tiwai@suse.de 2014-08-19T15:37:55+00:00 242af703ab4e00eeba1b82468706e430572f2392 commit dd5f5006d1035547559c8a90781a7e249787a7a2 upstream. The commit [5ee0f803cc3a: usbcore: don't log on consecutive debounce failures of the same port] added the check of the reliable port, but it also replaced the device argument to dev_err() wrongly, which leads to a NULL dereference. This patch restores the right device, port_dev->dev. Also, since dev_err() itself shows the port number, reduce the port number shown in the error message, essentially reverting to the state before the commit 5ee0f803cc3a.

commit dd5f5006d1035547559c8a90781a7e249787a7a2 upstream.

The commit [5ee0f803cc3a: usbcore: don't log on consecutive debounce
failures of the same port] added the check of the reliable port, but
it also replaced the device argument to dev_err() wrongly, which leads
to a NULL dereference.

This patch restores the right device, port_dev->dev.  Also, since

This patch fixes a potential security issue in the whiteheat USB driver which might allow a local attacker to cause kernel memory corrpution. This is due to an unchecked memcpy into a fixed size buffer (of 64 bytes). On EHCI and XHCI busses it's possible to craft responses greater than 64 bytes leading a buffer overflow.

xhci: rework cycle bit checking for new dequeue pointers 2014-09-05T23:36:40+00:00 Mathias Nyman mathias.nyman@linux.intel.com 2014-08-19T12:17:58+00:00 4914ed7547e1716c9fbec6e3ac865bdc0944467b commit 365038d83313951d6ace15342eb24624bbef1666 upstream. When we manually need to move the TR dequeue pointer we need to set the correct cycle bit as well. Previously we used the trb pointer from the last event received as a base, but this was changed in commit 1f81b6d22a59 ("usb: xhci: Prefer endpoint context dequeue pointer") to use the dequeue pointer from the endpoint context instead It turns out some Asmedia controllers advance the dequeue pointer stored in the endpoint context past the event triggering TRB, and this messed up the way the cycle bit was calculated. Instead of adding a quirk or complicating the already hard to follow cycle bit code, the whole cycle bit calculation is now simplified and adapted to handle event and endpoint context dequeue pointer differences.
