2010-09-24usb: musb: gadget: restart request on clearing endpoint haltSergei Shtylyov
Commit 46034dca515bc4ddca0399ae58106d1f5f0d809f (USB: musb_gadget_ep0: stop abusing musb_gadget_set_halt()) forgot to restart a queued request after clearing the endpoint halt feature. This results in a couple of USB resets while enumerating the file-backed storage gadget due to CSW packet not being sent for the MODE SENSE(10) command.

2010-09-24usb: musb: host: Issue a memory barrier before starting DMASantosh Shilimkar
This patch fixes the issue which was observed while transfering a large file ( > 20MB) over USB (OMAP MUSB controller acts as USB host) to an attached USB thumb drive. It was found that CDB field of CBW packet was set to 0x0. This was due to missing a barrier before DMA engine starts transfer. This buffer is allocated using dma_alloc_coherent which gives non-cacheble but bufferable memory and hence needed a write memory barrier to flush the write buffer.

2010-09-24usb: musb: gadget: enable autoclear for OUT transfer in both DMA 0 and DMA 1Ming Lei
This patch fixes one bugs of OUT transfer in double buffer case: -the current code only enable autoclear for dma mode 1, and not for dma mode 0 Without this patch, test #5 of usbtest can't be passed if we configure musb as g_zero and use fifo mode 3 to enable double buffer mode. With this patch and the following patch(fix dma length), on my beagle B5, test#5(queued bulk out) may go beyond 18Mbyte/s(seems dma mode 0 is quicker in double buffer case) if musb is configured as g_zero and fifo mode 3 is taken, follows the test command: #./testusb -D DEV_NAME -c 1024 -t 5 -s 32768 -g 8 [1] Also I have tested this patch can't make g_ether broken.

2010-09-24usb: musb: gadget: fix bulk IN infinit hangs in double buffer caseMing Lei
This patch fixes one infinite hang of bulk IN transfer in double buffer case, the hang can be observed easily by test #6 of usbtest if musb is configured as g_zero and fifo mode 3 is taken to enable double fifo. In fact, the patch only removes the check for non-empty fifo before loading data from new request into fifo since the check is not correct: -in double buffer case, fifo may accommodate more than one packet, even though it has contained one packet already and is non-empty -since last DMA is completed before calling musb_g_tx, it is sure that fifo may accommodate at least one packet Without applying the patch, new requst enqueued from .complte may not have a chance to be loaded into fifo, then will never be completed and cause infinite hangs. With the patch, on my beagle B5, test#6(queued bulk in) can be passed and test result may go beyond 33Mbyte/s if musb is configured as g_zero and fifo mode 3 is taken, follows the test command: #testusb -D DEV_NAME -c 1024 -t 6 -s 32768 -g 8 [1] [1], -source of testusb : tools/usb/testusb.c under linux kernel; Signed-off-by: Ming Lei <tom.leiming@gmail.com> Acked-by: Anand Gadiyar <gadiyar@ti.com> Cc: David Brownell <dbrownell@users.sourceforge.net> Cc: Anand Gadiyar <gadiyar@ti.com> Cc: Mike Frysinger <vapier@gentoo.org> Cc: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Felipe Balbi <balbi@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-09-24usb: musb: gadget: fix kernel panic if using out ep with FIFO_TXRX styleMing Lei
For shared fifo hw endpoint(with FIFO_TXRX style), only ep_in field of musb_hw_ep is intialized in musb_g_init_endpoints, and ep_out is not initialized, but musb_g_rx and rxstate may access ep_out field of musb_hw_ep by the method below: musb_ep = &musb->endpoints[epnum].ep_out which can cause the kernel panic[1] below, this patch fixes the issue by getting 'musb_ep' from '&musb->endpoints[epnum].ep_in' for shared fifo endpoint.

2010-09-24USB: fix bug in initialization of interface minor numbersAlan Stern
Recent changes in the usbhid layer exposed a bug in usbcore. If CONFIG_USB_DYNAMIC_MINORS is enabled then an interface may be assigned a minor number of 0. However interfaces that aren't registered as USB class devices also have their minor number set to 0, during initialization. As a result usb_find_interface() may return the wrong interface, leading to a crash. This patch (as1418) fixes the problem by initializing every interface's minor number to -1. It also cleans up the usb_register_dev() function, which besides being somewhat awkwardly written, does not unwind completely on all its error paths.

2010-09-22drivers/video/sis/sis_main.c: prevent reading uninitialized stack memoryDan Rosenberg
The FBIOGET_VBLANK device ioctl allows unprivileged users to read 16 bytes of uninitialized stack memory, because the "reserved" member of the fb_vblank struct declared on the stack is not altered or zeroed before being copied back to the user.

2010-09-22efifb: check that the base address is plausible on pci systemsPeter Jones
Some Apple machines have identical DMI data but different memory configurations for the video. Given that, check that the address in our table is actually within the range of a PCI BAR on a VGA device in the machine. This also fixes up the return value from set_system(), which has always been wrong, but never resulted in bad behavior since there's only ever been one matching entry in the dmi table. The patch 1) stops people's machines from crashing when we get their display wrong, which seems to be unfortunately inevitable, 2) allows us to support identical dmi data with differing video memory configurations This also adds me as the efifb maintainer, since I've effectively been acting as such for quite some time.

The "h->scatter_list" is allocated inside a for loop. If any of those allocations fail, then the rest of the list is uninitialized data. When we free it we should start from the top and free backwards so that we don't call kfree() on uninitialized pointers. Also if the allocation for "h->scatter_list" fails then we would get an Oops here. I should have noticed this when I send: 4ee69851c "cciss: handle allocation failure." but I didn't.

A userspace could submit a buffer with 0 length to be written to the host. Prevent such a situation. This was not needed previously, but recent changes in the way write() works exposed this condition to trigger a virtqueue event to the host, causing a NULL buffer to be sent across.

2010-09-21virtio: console: Fix poll blocking even though there is data to readHans de Goede
I found this while working on a Linux agent for spice, the symptom I was seeing was select blocking on the spice vdagent virtio serial port even though there were messages queued up there. virtio_console's port_fops_poll checks port->inbuf != NULL to determine if read won't block. However if an application reads enough bytes from inbuf through port_fops_read, to empty the current port->inbuf, port->inbuf will be NULL even though there may be buffers left in the virtqueue. This causes poll() to block even though there is data to be read, this patch fixes this by using will_read_block(port) instead of the port->inbuf != NULL check.

2010-09-20Staging: vt6655: fix buffer overflowDan Carpenter
"param->u.wpa_associate.wpa_ie_len" comes from the user. We should check it so that the copy_from_user() doesn't overflow the buffer. Also further down in the function, we assume that if "param->u.wpa_associate.wpa_ie_len" is set then "abyWPAIE[0]" is initialized. To make that work, I changed the test here to say that if "wpa_ie_len" is set then "wpa_ie" has to be a valid pointer or we return -EINVAL. Oddly, we only use the first element of the abyWPAIE[] array. So I suspect there may be some other issues in this function.

This reverts commit 96d592ed599434d2d5f339a1d282871bc6377d2c. The netfilter hook seems to be misused and may leak skbs in situations when NF_HOOK returns NF_STOLEN. It may not filter everything as expected. Also the ethernet bridge tables are not yet capable to understand batman-adv packet correctly. It was only added for testing purposes and can be removed again.

2010-09-20USB: otg: twl4030: fix phy initialization(v1)Ming Lei
Commit 461c317705eca5cac09a360f488715927fd0a927(into 2.6.36-v3) is put forward to power down phy if no usb cable is connected, but does introduce the two issues below: 1), phy is not into work state if usb cable is connected with PC during poweron, so musb device mode is not usable in such case, follows the reasons: -twl4030_phy_resume is not called, so regulators are not enabled i2c access are not enabled usb mode not configurated 2), The kernel warings[1] of regulators 'unbalanced disables' is caused if poweron without usb cable connected with PC or b-device. This patch fixes the two issues above: -power down phy only if no usb cable is connected with PC and b-device -do phy initialization(via __twl4030_phy_resume) if usb cable is connected with PC(vbus event) or another b-device(ID event) in twl4030_usb_probe. This patch also doesn't put VUSB3V1 LDO into active mode in twl4030_usb_ldo_init until VBUS/ID change detected, so we can save more power consumption than before. This patch is verified OK on Beagle board either connected with usb cable or not when poweron. [1]. warnings of 'unbalanced disables' of regulators.

2010-09-20usb: musb_debugfs: don't use the struct file private_data field with seq_filesMathias Nyman
seq_files use the private_data field of a file struct for storing a seq_file structure, data should be stored in seq_file's own private field (e.g. file->private_data->private) Otherwise seq_release() will free the private data when the file is closed.

2010-09-20drm/i915: Hold a reference to the object whilst unbinding the eviction listChris Wilson
During heavy aperture thrashing we may be forced to wait upon several active objects during eviction. The active list may be the last reference to these objects and so the action of waiting upon one of them may cause another to be freed (and itself unbound). To prevent the object disappearing underneath us, we need to acquire and hold a reference whilst unbinding. This should fix the reported page refcount OOPS: kernel BUG at drivers/gpu/drm/i915/i915_gem.c:1444! ...
