commit 5c915c68 upstream. On my bttv card "Hauppauge WinTV [card=10]" capturing in YV12 fmt at max size results in a solid green rectangle being captured (all colors 0 in YUV). This turns out to be caused by max-width (924) not being a multiple of 16. We've likely never hit this problem before since normally xawtv / tvtime, etc. will prefer packed pixel formats. But when using a video card which is using xf86-video-modesetting + glamor, only planar XVideo fmts are available, and xawtv will chose a matching capture format to avoid needing to do conversion, triggering the solid green window problem.

commit b339a72e upstream. The V4L2_CID_TX_EDID_PRESENT control reports if an EDID is present. The adv7511 however still reported the EDID present after disconnecting the HDMI cable. Fix the logic regarding this control. And when the EDID is disconnected also call ADV7511_EDID_DETECT to notify the bridge driver. This was also missing. Signed-off-by:

commit 401879c5 upstream. The N_IRDA line discipline may access the previous line discipline's closed and already-fre private data on open [1]. The tty->disc_data field _never_ refers to valid data on entry to the line discipline's open() method. Rather, the ldisc is expected to initialize that field for its own use for the lifetime of the instance (ie. from open() to close() only).

commit ce0ae266 upstream. Since a crypto_ahash_import() can be called against a request context that has not had a crypto_ahash_init() performed, the request context needs to be cleared to insure there is no random data present. If not, the random data can result in a kernel oops during crypto_ahash_update(). Signed-off-by:

commit 952bce97 upstream. Commit 8996eafd ("crypto: ahash - ensure statesize is non-zero") added a check to prevent ahash algorithms from successfully registering if the import and export functions were not implemented. This prevents an oops in the hash_accept function of algif_hash. This commit causes the ccp-crypto module SHA support and AES CMAC support from successfully registering and causing the ccp-crypto module load to fail because the ahash import and export functions are not implemented. Update the CCP Crypto API support to provide import and export support for ahash algorithms. Signed-off-by:

commit 836b34a9 upstream. create_fixed_stream_quirk(), snd_usb_parse_audio_interface() and create_uaxx_quirk() functions allocate the audioformat object by themselves and free it upon error before returning. However, once the object is linked to a stream, it's freed again in snd_usb_audio_pcm_free(), thus it'll be double-freed, eventually resulting in a memory corruption. This patch fixes these failures in the error paths by unlinking the audioformat object before freeing it. Based on a patch by Takashi Iwai <tiwai@suse.de> [Note for stable backports: this patch requires the commit 902eb7fd ('ALSA: usb-audio: Minor code cleanup in create_fixed_stream_quirk()')] Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1283358Reported-by:

commit 447d6275 upstream. Add some sanity check codes before actually accessing the endpoint via get_endpoint() in order to avoid the invalid access through a malformed USB descriptor. Mostly just checking bNumEndpoints, but in one place (snd_microii_spdif_default_get()), the validity of iface and altsetting index is checked as well.

commit 264904cc upstream. Some devices I got show an inability to operate right after power on if they are already connected. They are beyond recovery if the descriptors are requested multiple times. So in case of a timeout we rather bail early and reset again. But it must be done only on the first loop lest we get into a reset/time out spiral that can be overcome with a retry. This patch is a rework of a patch that fell through the cracks. http://www.spinics.net/lists/linux-usb/msg103263.htmlSigned-off-by:

commit f88fa79a upstream. aac_fib_map_free() calls pci_free_consistent() without checking that dev->hw_fib_va is not NULL and dev->max_fib_size is not zero.If they are indeed NULL/0, this will result in a hang as pci_free_consistent() will attempt to invalidate cache for the entire 64-bit address space (which would take a very long time). Fixed by adding a check to make sure that dev->hw_fib_va and dev->max_fib_size are not NULL and 0 respectively.

commit 5ecee0a3 upstream. One of the strange things that the original sg driver did was let the user provide both a data-out buffer (it followed the sg_header+cdb) _and_ specify a reply length greater than zero. What happened was that the user data-out buffer was copied into some kernel buffers and then the mid level was told a read type operation would take place with the data from the device overwriting the same kernel buffers. The user would then read those kernel buffers back into the user space. From what I can tell, the above action was broken by commit fad7f01e ("sg: set dxferp to NULL for READ with the older SG interface") in 2008 and syzkaller found that out recently. Make sure that a user space pointer is passed through when data follows the sg_header structure and command. Fix the abnormal case when a non-zero reply_len is also given.

commit b84106b4 upstream. The PCI config header (first 64 bytes of each device's config space) is defined by the PCI spec so generic software can identify the device and manage its usage of I/O, memory, and IRQ resources. Some non-spec-compliant devices put registers other than BARs where the BARs should be. When the PCI core sizes these "BARs", the reads and writes it does may have unwanted side effects, and the "BAR" may appear to describe non-sensical address space. Add a flag bit to mark non-compliant devices so we don't touch their BARs. Turn off IO/MEM decoding to prevent the devices from consuming address space, since we can't read the BARs to find out what that address space would be. Signed-off-by:
