2010-11-05usb: musb: fix kernel oops when loading musb_hdrc module for the 2nd timeMing Lei
musb driver still may write MUSB_DEVCTL register after clock is disabled in musb_platform_exit, which may cause the kernel oops[1] when musb_hdrc module is loaded for the 2nd time. The patch fixes the kernel oops in this case.

2010-11-05USB: musb: gadget: fix MUSB_TXMAXP and MUSB_RXMAXP configurationMing Lei
Commit 9f445cb29918dc488b7a9a92ef018599cce33df7[USB: musb: disable double buffering for older RTL versions] tries to disable double buffer mode by writing endpoint hw max packet size to TXMAP/RXMAP. First the approach can break full speed and cause overflow problems. We should always set those registers with the actual max packet size from endpoint descriptor. Second, the problem describe by commit 9f445cb29918dc488b7a9a92ef018599cce33df7 was caused by musb gadget driver; nothing to do with RTL revision as originaly suspected. The real fix to the problem is to always use actual max packet size from endpoint descriptor to config TXMAP/RXMAP registers.

2010-11-05usb: musb: don't leave PHY enabled on shutdown()Grazvydas Ignotas
Some actions like musb_platform_exit are only performed on module removal and not on shutdown, which results in PHY being left enabled on reboot at least. This is sometimes causing strange failures after reboot (observed on OMAP3 pandora board), when DEVCTL does not report VBUS state correctly due to unknown reasons (possibly because of communication issues between musb IP and PHY). Running musb_platform_exit before reset seems to resolve that issue. Move some exit code from musb_remove() to musb_shutdown() so that it is performed on both module removal and shutdown/reset. Also convert the host check so that it doesn't need #ifdef. Signed-off-by: Grazvydas Ignotas <notasas@gmail.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

2010-11-05usb: musb: gadget: fix dma mode 0 in double buffer Rx caseMing Lei
1, In Rx double buffer case, FIFO may have two packets, so rxstate should be called to unload fifo if RXPKTRDY is set even the current request has not been completed. 2, Commit 633ba7876b96ec339ef685357e2f7c60b5a8ce85 introduces autoclear to support double buffer in dma mode 0, so remove clearing RXPKTRDY manually for dma mode 0. 3, Commit c7af6b29ffeffbeb28caf39e5b2ce29b11807c7d may break dma mode 1 for non-doublebuffer endpoint, fix it. With this patch, either usbtest #5 or g_file_storage(writing file to device in usb host) or g_ether have been tested OK in double buffer case(using fifo mode 3). Also, this patch has been verified that single buffer case can't be broken.

2010-11-04cifs: dereferencing first then checkingJeff Layton
This patch is based on Dan's original patch. His original description is below: Smatch complained about a couple checking for NULL after dereferencing bugs. I'm not super familiar with the code so I did the conservative thing and move the dereferences after the checks. The dereferences in cifs_lock() and cifs_fsync() were added in ba00ba64cf0 "cifs: make various routines use the cifsFileInfo->tcon pointer". The dereference in find_writable_file() was added in 6508d904e6f "cifs: have find_readable/writable_file filter by fsuid". The comments there say it's possible to trigger the NULL dereference under stress.

We were using nlmsg_find_attr() to look up the bytecode by attribute when auditing, but then just using the first attribute when actually running bytecode. So, if we received a message with two attribute elements, where only the second had type INET_DIAG_REQ_BYTECODE, we would validate and run different bytecode strings.

2010-11-04crypto: padlock - Fix AES-CBC handling on odd-block-sized inputHerbert Xu
On certain VIA chipsets AES-CBC requires the input/output to be a multiple of 64 bytes. We had a workaround for this but it was buggy as it sent the whole input for processing when it is meant to only send the initial number of blocks which makes the rest a multiple of 64 bytes. As expected this causes memory corruption whenever the workaround kicks in. Reported-by: Phil Sutter <phil@nwl.cc> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2010-11-04Input: atkbd - add 'terminal' parameter for IBM Terminal keyboardsBenjamin LaHaise
Many of the IBM Terminal keyboards from the 1980s and early 1990s communicate using a protocol similar, but not identical to the AT keyboard protocol. (Models known to be like this include 6110344, 6110668, 1390876, 1386887, and possibly others.) When the connector is rewired or adapter to an AT-DIN or PS/2 connector, they can be connected to a standard PC, with three caveats: a) They can only use scancode set 3; requests to use anything else are quietly ignored. b) The AT Command to request Make, Break and Repeat codes is not properly interpreted. c) The top function keys on a 122 key keyboard, and the arrow/edit keys in the middle of the board send non-standard scancodes. C) is easily taken care of in userspace, by use of setkeycodes B) can be taken care of by a userspace hack (that makes the kernel complain in dmesg) A) is fixable in theory, but on the keyboard i tested on (6110668), it seems to be detected unoverridably as Set 2, causing userspace oddities that make it harder to fix C). Enclosed is a small patch to the kernel that fixes A) and B) in the kernel, making it much easier to fix C) in userspace. It adds a single kernel command line parameter that overrides the detection that sets these boards as set 2, and instead of sending the Make-break-repeat command to the keyboard, it sends the make-break command, which is properly recognized by these keyboards. Software level key repeating seems to make up for the lack of hardware repeat codes perfectly. Without manually setting the command line parameter (tentatively named atkbd.terminal), this code has no effect, and the driver works exactly as before.

2010-11-04Input: i8042 - add Sony VAIOs to MUX blacklistJesse Barnes
The Sony VPCZ1 doesn't support active multiplexing and trying to enable it causes keyboard to stop working. Since most (all?) VAIOs do not have external PS/2 ports nor they implement active multiplexing properly, and trying to enable MUX usually messes up keyboard/touchpad, let's simply disable MUX probing based on board name (VAIO).

2010-11-03net dst: fix percpu_counter list corruption and poison overwrittenXiaotian Feng
There're some percpu_counter list corruption and poison overwritten warnings in recent kernel, which is resulted by fc66f95c. commit fc66f95c switches to use percpu_counter, in ip6_route_net_init, kernel init the percpu_counter for dst entries, but, the percpu_counter is never destroyed in ip6_route_net_exit. So if the related data is freed by kernel, the freed percpu_counter is still on the list, then if we insert/remove other percpu_counter, list corruption resulted. Also, if the insert/remove option modifies the ->prev,->next pointer of the freed value, the poison overwritten is resulted then. With the following patch, the percpu_counter list corruption and poison overwritten warnings disappeared. Signed-off-by: Xiaotian Feng <dfeng@redhat.com> Cc: "David S.
