      ovl: simplify empty checking · 30c17ebf
      Miklos Szeredi authored
      The empty checking logic is duplicated in ovl_check_empty_and_clear() and
      ovl_remove_and_whiteout(), except the condition for clearing whiteouts is
      different:
      
      ovl_check_empty_and_clear() checked for being upper
      
      ovl_remove_and_whiteout() checked for merge OR lower
      
      Move the intersection of those checks (upper AND merge) into
      ovl_check_empty_and_clear() and simplify ovl_remove_and_whiteout().

      This does not work and does not make sense.  So instead of fixing it
      (probably not hard) just disallow.

      ovl: append MAY_READ when diluting write checks · 500cac3c
      Vivek Goyal authored
      Right now we remove MAY_WRITE/MAY_APPEND bits from mask if realfile is on
      lower/. This is done as files on lower will never be written and will be
      copied up. But to copy up a file, mounter should have MAY_READ permission
      otherwise copy up will fail. So set MAY_READ in mask when MAY_WRITE is
      reset.
      
      Dan Walsh noticed this when he did access(lowerfile, W_OK) and it returned
      True (context mounts) but when he tried to actually write to file, it
      failed as mounter did not have permission on lower file.
      
      [SzM] don't set MAY_READ if only MAY_APPEND is set without MAY_WRITE; this
      won't trigger a copy-up.

      ovl: fix POSIX ACL setting · d837a49b
      Miklos Szeredi authored
      Setting POSIX ACL needs special handling:
      
      1) Some permission checks are done by ->setxattr() which now uses mounter's
      creds ("ovl: do operations on underlying file system in mounter's
      context").  These permission checks need to be done with current cred as
      well.
      
      2) Setting ACL can fail for various reasons.  We do not need to copy up in
      these cases.
      
      In the mean time switch to using generic_setxattr.
      
      [Arnd Bergmann] Fix link error without POSIX ACL. posix_acl_from_xattr()
      doesn't have a 'static inline' implementation when CONFIG_FS_POSIX_ACL is
      disabled, and I could not come up with an obvious way to do it.
      
      This instead avoids the link error by defining two sets of ACL operations
      and letting the compiler drop one of the two at compile time depending
      on CONFIG_FS_POSIX_ACL. This avoids all references to the ACL code,
      also leading to smaller code.

      ovl: share inode for hard link · 51f7e52d
      Miklos Szeredi authored
      Inode attributes are copied up to overlay inode (uid, gid, mode, atime,
      mtime, ctime) so generic code using these fields works correcty.  If a hard
      link is created in overlayfs separate inodes are allocated for each link.
      If chmod/chown/etc. is performed on one of the links then the inode
      belonging to the other ones won't be updated.
      
      This patch attempts to fix this by sharing inodes for hard links.
      
      Use inode hash (with real inode pointer as a key) to make sure overlay
      inodes are shared for hard links on upper.  Hard links on lower are still
      split (which is not user observable until the copy-up happens, see
      Documentation/filesystems/overlayfs.txt under "Non-standard behavior").
      
      The inode is only inserted in the hash if it is non-directoy and upper.

      ovl: store real inode pointer in ->i_private · 39b681f8
      Miklos Szeredi authored
      To get from overlay inode to real inode we currently use 'struct
      ovl_entry', which has lifetime connected to overlay dentry.  This is okay,
      since each overlay dentry had a new overlay inode allocated.
      
      Following patch will break that assumption, so need to leave out ovl_entry.
      This patch stores the real inode directly in i_private, with the lowest bit
      used to indicate whether the inode is upper or lower.
      
      Lifetime rules remain, using ovl_inode_real() must only be done while
      caller holds ref on overlay dentry (and hence on real dentry), or within
      RCU protected regions.

      ovl: update atime on upper · d719e8f2
      Miklos Szeredi authored
      Fix atime update logic in overlayfs.
      
      This patch adds an i_op->update_time() handler to overlayfs inodes.  This
      forwards atime updates to the upper layer only.  No atime updates are done
      on lower layers.
      
      Remove implicit atime updates to underlying files and directories with
      O_NOATIME.  Remove explicit atime update in ovl_readlink().
      
      Clear atime related mnt flags from cloned upper mount.  This means atime
      updates are controlled purely by overlayfs mount options.

      ovl: fix sgid on directory · bb0d2b8a
      Miklos Szeredi authored
      When creating directory in workdir, the group/sgid inheritance from the
      parent dir was omitted completely.  Fix this by calling inode_init_owner()
      on overlay inode and using the resulting uid/gid/mode to create the file.
      
      Unfortunately the sgid bit can be stripped off due to umask, so need to
      reset the mode in this case in workdir before moving the directory in
      place.

      ovl: simplify permission checking · 9c630ebe
      Miklos Szeredi authored
      The fact that we always do permission checking on the overlay inode and
      clear MAY_WRITE for checking access to the lower inode allows cruft to be
      removed from ovl_permission().
      
      1) "default_permissions" option effectively did generic_permission() on the
      overlay inode with i_mode, i_uid and i_gid updated from underlying
      filesystem.  This is what we do by default now.  It did the update using
      vfs_getattr() but that's only needed if the underlying filesystem can
      change (which is not allowed).  We may later introduce a "paranoia_mode"
      that verifies that mode/uid/gid are not changed.
      
      2) splitting out the IS_RDONLY() check from inode_permission() also becomes
      unnecessary once we remove the MAY_WRITE from the lower inode check.

      ovl: do not require mounter to have MAY_WRITE on lower · 754f8cb7
      Vivek Goyal authored
      Now we have two levels of checks in ovl_permission(). overlay inode
      is checked with the creds of task while underlying inode is checked
      with the creds of mounter.
      
      Looks like mounter does not have to have WRITE access to files on lower/.
      So remove the MAY_WRITE from access mask for checks on underlying
      lower inode.
      
      This means task should still have the MAY_WRITE permission on lower
      inode and mounter is not required to have MAY_WRITE.
      
      It also solves the problem of read only NFS mounts being used as lower.
      If __inode_permission(lower_inode, MAY_WRITE) is called on read only
      NFS, it fails. By resetting MAY_WRITE, check succeeds and case of
      read only NFS shold work with overlay without having to specify any
      special mount options (default permission).

      ovl: check mounter creds on underlying lookup · c1b2cc1a
      Miklos Szeredi authored
      The hash salting changes meant that we can no longer reuse the hash in the
      overlay dentry to look up the underlying dentry.
      
      Instead of lookup_hash(), use lookup_one_len_unlocked() and swith to
      mounter's creds (like we do for all other operations later in the series).
      
      Now the lookup_hash() export introduced in 4.6 by 3c9fe8cd ("vfs: add
      lookup_hash() helper") is unused and can possibly be removed; its
      usefulness negated by the hash salting and the idea that mounter's creds
      should be used on operations on underlying filesystems.

      Pull key handling fixes from James Morris:
       "Quoting David Howells:
      
        Here are three miscellaneous fixes:
      
        (1) Fix a panic in some debugging code in PKCS#7.  This can only
            happen by explicitly inserting a #define DEBUG into the code.
      
        (2) Fix the calculation of the digest length in the PE file parser.
            This causes a failure where there should be a success.
      
        (3) Fix the case where an X.509 cert can be added as an asymmetric key
            to a trusted keyring with no trust restriction if no AKID is
            supplied.
      
        Bugs (1) and (2) aren't particularly problematic, but (3) allows a
        security check to be bypassed.  Happily, this is a recent regression
        and never made it into a released kernel"

      Pull libnvdimm fix from Dan Williams:
       "This contains a regression fix for a problem that was introduced in
        v4.7-rc6.
      
        In 4.7-rc1 we introduced auto-probing for the ACPI DSM (device-
        specific-method) format that the platform firmware implements for
        nvdimm devices.  We initially fixed a regression in probing the QEMU
        DSM implementation by making acpi_check_dsm() tolerant of the way QEMU
        reports the "0 DSMs supported" condition.
      
        However, that broke HPE platforms since that tolerance caused the
        driver to mistakenly match the 1-zero-byte response those platforms
        give to "unknown" commands.  Instead, we simply make the driver
        tolerant of not finding any supported DSMs.  This has been tested to
        work with both QEMU and HPE platforms.
      
        This commit has appeared in a -next release with no reported issues"
