linux-toradex.git/drivers/usb, branch v2.6.26.3 Linux kernel for Apalis and Colibri modules usb-storage: automatically recognize bad residues 2008-08-20T18:05:14+00:00 Alan Stern stern@rowland.harvard.edu 2008-08-05T14:46:23+00:00 978e8c75a78d16d933dfa471fa247e7e61c9f7a4 commit 59f4ff2ecff4cef36378928cec891785b402e80c upstream This patch (as1119b) will help to reduce the clutter of usb-storage's unusual_devs file by automatically detecting some devices that need the IGNORE_RESIDUE flag. The idea is that devices should never return a non-zero residue for an INQUIRY or a READ CAPACITY command unless they failed to transfer all the requested data. So if one of these commands transfers a standard amount of data but there is a positive residue, we know that the residue is bogus and we can set the flag. This fixes the problems reported in Bugzilla #11125.

unusual_devs file by automatically detecting some devices that need
the IGNORE_RESIDUE flag.  The idea is that devices should never return

they failed to transfer all the requested data.  So if one of these
commands transfers a standard amount of data but there is a positive

usb-storage: revert DMA-alignment change for Wireless USB 2008-08-20T18:05:14+00:00 Alan Stern stern@rowland.harvard.edu 2008-08-11T14:08:17+00:00 b0d87b9307f9e4b5803a3cad3ad00bee4beb1966 commit f756cbd458ab71c996a069cb3928fb1e2d7cd9cc upstream. This patch (as1110) reverts an earlier patch meant to help with Wireless USB host controllers. These controllers can have bulk maxpacket values larger than 512, which puts unusual constraints on the sizes of scatter-gather list elements. However it turns out that the block layer does not provide the support we need to enforce these constraints; merely changing the DMA alignment mask doesn't help. Hence there's no reason to keep the original patch. The Wireless USB problem will have to be solved a different way. In addition, there is a reason to get rid of the earlier patch. By dereferencing a pointer stored in the ep_in array of struct usb_device, the current code risks an invalid memory access when it runs concurrently with device removal. The members of that array are cleared before the driver's disconnect method is called, so it should not try to use them.
