2016-07-31hwmon: (ftsteutates) Fix potential memory access errorGuenter Roeck
Using set_bit() to set a bit in an integer is not a good idea, since the function expects an unsigned long as argument, which can be 64 bit wide. Coverity reports this problem as >>> CID 1364488: Memory - illegal accesses (INCOMPATIBLE_CAST) >>> Pointer "&ret" points to an object whose effective type is "int" >>> (32 bits, signed) but is dereferenced as a wider "unsigned +long" (64 bits, unsigned). This may lead to memory corruption. 245 set_bit(1, (unsigned long *)&ret); Just use BIT instead.

2016-07-31random: Fix crashes with sparse node idsMichael Ellerman
On a system with sparse node ids, eg. a powerpc system with 4 nodes numbered like so: node 0: [mem 0x0000000000000000-0x00000007ffffffff] node 1: [mem 0x0000000800000000-0x0000000fffffffff] node 16: [mem 0x0000001000000000-0x00000017ffffffff] node 17: [mem 0x0000001800000000-0x0000001fffffffff] The code in rand_initialize() will allocate 4 pointers for the pool array, and initialise them correctly. However when go to use the pool, in eg. extract_crng(), we use the numa_node_id() to index into the array. For the higher numbered node ids this leads to random memory corruption, depending on what was kmalloc'ed adjacent to the pool array. Fix it by using nr_node_ids to size the pool array.

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.

2016-07-29documentation: da9052: Update regulator bindings names to match DA9052/53 ↵Steve Twiss
DTS expectations Buck and LDO binding name changes. The binding names for the regulators have been changed to match the current expectation from existing device tree source files. This fix rectifies the disparity between what currently exists in some .dts[i] board files and what is listed in this binding document. This change re-aligns those differences and also brings the binding document in-line with the expectations of the product datasheet from Dialog Semiconductor. Bucks and LDOs now follow the expected notation: { buck1, buck2, buck3, buck4 } { ldo1, ldo2, ldo3, ldo4, ldo5, ldo6, ldo7, ldo8, ldo9, ldo10 } Signed-off-by: Steve Twiss <stwiss.opensource@diasemi.com> Signed-off-by: Rob Herring <robh@kernel.org>
