2014-07-08staging: octeon-usb: don't retry on data toggle errorAaro Koskinen1-2/+3
On data toggle error, we don't know if and how many bytes were successfully transferred by DMA. We should just fail the transaction instead of trying a retry. Signed-off-by: Aaro Koskinen <aaro.koskinen@iki.fi> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-07-08staging: octeon-usb: use usb_hcd_link_urb_to_ep()Aaro Koskinen1-1/+17
The driver did not use link_urb_to_ep() / unlink_urb_from_ep(). This caused odd behaviour in some error recovery situations, all requests would start to fail after the first failure. Signed-off-by: Aaro Koskinen <aaro.koskinen@iki.fi> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2014-03-20staging: octeon-usb: prevent memory corruptionAaro Koskinen1-0/+108
octeon-hcd will crash the kernel when SLOB is used. This usually happens after the 18-byte control transfer when a device descriptor is read. The DMA engine is always transfering full 32-bit words and if the transfer is shorter, some random garbage appears after the buffer. The problem is not visible with SLUB since it rounds up the allocations to word boundary, and the extra bytes will go undetected. Fix by providing quirk functions for DMA map/unmap that allocate a bigger temporary buffer when necessary. Tested by booting EdgeRouter Lite to USB stick root file system with SLAB, SLOB and SLUB kernels.
