2016-07-30qed: Don't over-do producer cleanup for RxYuval Mintz
Before requesting the firmware to start Rx queues, driver goes and sets the queue producer in the device to 0. But while the producer is 32-bit, the driver currently clears 64 bits, effectively zeroing an additional CID's producer as well.

2016-07-30qed: Fix removal of spoof checking for VFsYuval Mintz
Driver has reverse logic for checking the result of the spoof-checking configuration. As a result, it would log that the configuration failed [even though it succeeded], and will no longer do anything when requested to remove the configuration, as it's accounting of the feature will be incorrect.

2016-07-30qede: Don't try removing unconfigured vlansYuval Mintz
As part of ndo_vlan_rx_kill_vid() implementation, qede is requesting firmware to remove the vlan filter. This currently happens even if the vlan wasn't previously added [In case device ran out of vlan credits]. For PFs this doesn't cause any issues as the firmware would simply ignore the removal request. But for VFs their parent PF is holding an accounting of the configured vlans, and such a request would cause the PF to fail the VF's removal request. Simply fix this for both PFs & VFs and don't remove filters that were not previously added.

2016-07-30drm/nouveau/acpi: fix lockup with PCIe runtime PMPeter Wu
Since "PCI: Add runtime PM support for PCIe ports", the parent PCIe port can be runtime-suspended which disables power resources via ACPI. This is incompatible with DSM, resulting in a GPU device which is still in D3 and locks up the kernel on resume (on a Clevo P651RA, GTX965M). Mirror the behavior of Windows 8 and newer[1] (as observed via an AMLi debugger trace) and stop using the DSM functions for D3cold when power resources are available on the parent PCIe port. pci_d3cold_disable() is not used because on some machines, the old DSM method is broken. On a Lenovo T440p (GT 730M) memory and disk corruption would occur, but that is fixed with this patch[2].

2016-07-30drm/nouveau/fbcon: fix font width not divisible by 8Mikulas Patocka
The patch f045f459d925 ("drm/nouveau/fbcon: fix out-of-bounds memory accesses") tries to fix some out of memory accesses. Unfortunatelly, the patch breaks the display when using fonts with width that is not divisiable by 8. The monochrome bitmap for each character is stored in memory by lines from top to bottom. Each line is padded to a full byte. For example, for 22x11 font, each line is padded to 16 bits, so each character is consuming 44 bytes total, that is 11 32-bit words. The patch f045f459d925 changed the logic to "dsize = ALIGN(image->width * image->height, 32) >> 5", that is just 8 words - this is incorrect and it causes display corruption. This patch adds the necesary padding of lines to 8 bytes. This patch should be backported to stable kernels where f045f459d925 was backported.

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull userns vfs updates from Eric Biederman: "This tree contains some very long awaited work on generalizing the user namespace support for mounting filesystems to include filesystems with a backing store. The real world target is fuse but the goal is to update the vfs to allow any filesystem to be supported. This patchset is based on a lot of code review and testing to approach that goal. While looking at what is needed to support the fuse filesystem it became clear that there were things like xattrs for security modules that needed special treatment. That the resolution of those concerns would not be fuse specific. That sorting out these general issues made most sense at the generic level, where the right people could be drawn into the conversation, and the issues could be solved for everyone. At a high level what this patchset does a couple of simple things: - Add a user namespace owner (s_user_ns) to struct super_block. - Teach the vfs to handle filesystem uids and gids not mapping into to kuids and kgids and being reported as INVALID_UID and INVALID_GID in vfs data structures. By assigning a user namespace owner filesystems that are mounted with only user namespace privilege can be detected. This allows security modules and the like to know which mounts may not be trusted. This also allows the set of uids and gids that are communicated to the filesystem to be capped at the set of kuids and kgids that are in the owning user namespace of the filesystem. One of the crazier corner casees this handles is the case of inodes whose i_uid or i_gid are not mapped into the vfs. Most of the code simply doesn't care but it is easy to confuse the inode writeback path so no operation that could cause an inode write-back is permitted for such inodes (aka only reads are allowed). This set of changes starts out by cleaning up the code paths involved in user namespace permirted mounts. Then when things are clean enough adds code that cleanly sets s_user_ns. Then additional restrictions are added that are possible now that the filesystem superblock contains owner information. These changes should not affect anyone in practice, but there are some parts of these restrictions that are changes in behavior. - Andy's restriction on suid executables that does not honor the suid bit when the path is from another mount namespace (think /proc/[pid]/fd/) or when the filesystem was mounted by a less privileged user. - The replacement of the user namespace implicit setting of MNT_NODEV with implicitly setting SB_I_NODEV on the filesystem superblock instead. Using SB_I_NODEV is a stronger form that happens to make this state user invisible. The user visibility can be managed but it caused problems when it was introduced from applications reasonably expecting mount flags to be what they were set to. There is a little bit of work remaining before it is safe to support mounting filesystems with backing store in user namespaces, beyond what is in this set of changes. - Verifying the mounter has permission to read/write the block device during mount. - Teaching the integrity modules IMA and EVM to handle filesystems mounted with only user namespace root and to reduce trust in their security xattrs accordingly. - Capturing the mounters credentials and using that for permission checks in d_automount and the like. (Given that overlayfs already does this, and we need the work in d_automount it make sense to generalize this case). Furthermore there are a few changes that are on the wishlist: - Get all filesystems supporting posix acls using the generic posix acls so that posix_acl_fix_xattr_from_user and posix_acl_fix_xattr_to_user may be removed. [Maintainability] - Reducing the permission checks in places such as remount to allow the superblock owner to perform them. - Allowing the superblock owner to chown files with unmapped uids and gids to something that is mapped so the files may be treated normally. I am not considering even obvious relaxations of permission checks until it is clear there are no more corner cases that need to be locked down and handled generically.

2016-07-29ubi: Be more paranoid while seaching for the most recent FastmapRichard Weinberger
Since PEB erasure is asynchornous it can happen that there is more than one Fastmap on the MTD. This is fine because the attach logic will pick the Fastmap data structure with the highest sequence number. On a not so well configured MTD stack spurious ECC errors are common. Causes can be different, bad hardware, wrong operating modes, etc... If the most current Fastmap renders bad due to ECC errors UBI might pick an older Fastmap to attach from. While this can only happen on an anyway broken setup it will show completely different sympthoms and makes finding the root cause much more difficult. So, be debug friendly and fall back to scanning mode of we're facing an ECC error while scanning for Fastmap. Cc: <stable@vger.kernel.org> Signed-off-by: Richard Weinberger <richard@nod.at>

2016-07-29ubi: Make volume resize power cut awareRichard Weinberger
When the volume resize operation shrinks a volume, LEBs will be unmapped. Since unmapping will not erase these LEBs immediately we have to wait for that operation to finish. Otherwise in case of a power cut right after writing the new volume table the UBI attach process can find more LEBs than the volume table knows. This will render the UBI image unattachable. Fix this issue by waiting for erase to complete and write the new volume table afterward.
