  • 4e34e719e   fs: take the ACL checks to common code ... Browse Code »

    Replace the ->check_acl method with a ->get_acl method that simply reads an
    ACL from disk after having a cache miss. This means we can replace the ACL
    checking boilerplate code with a single implementation in namei.c.

  • 826cae2f2   kill boilerplates around posix_acl_create_masq() ... Browse Code »

    new helper: posix_acl_create(&acl, gfp, mode_p). Replaces acl with
    modified clone, on failure releases acl and replaces with NULL.
    Returns 0 or -ve on error. All callers of posix_acl_create_masq()
    switched.

  • bc26ab5f6   kill boilerplate around posix_acl_chmod_masq() ... Browse Code »

    new helper: posix_acl_chmod(&acl, gfp, mode). Replaces acl with modified
    clone or with NULL if that has failed; returns 0 or -ve on error. All
    callers of posix_acl_chmod_masq() switched to that - they'd been doing
    exactly the same thing.

  • e77819e57   vfs: move ACL cache lookup into generic code ... Browse Code »

    This moves logic for checking the cached ACL values from low-level
    filesystems into generic code. The end result is a streamlined ACL
    check that doesn't need to load the inode->i_op->check_acl pointer at
    all for the common cached case.

    The filesystems also don't need to check for a non-blocking RCU walk
    case in their acl_check() functions, because that is all handled at a
    VFS layer.

  • 431547b3c   sanitize xattr handler prototypes ... Browse Code »

    Add a flags argument to struct xattr_handler and pass it to all xattr
    handler methods. This allows using the same methods for multiple
    handlers, e.g. for the ACL methods which perform exactly the same action
    for the access and default ACLs, just using a different underlying
    attribute. With a little more groundwork it'll also allow sharing the
    methods for the regular user/trusted/secure handlers in extN, ocfs2 and
    jffs2 like it's already done for xfs in this patch.

    Also change the inode argument to the handlers to a dentry to allow
    using the handlers mechnism for filesystems that require it later,
    e.g. cifs.

    [with GFS2 bits updated by Steven Whitehouse ]

  • e6305c43e   [PATCH] sanitize ->permission() prototype ... Browse Code »

    * kill nameidata * argument; map the 3 bits in ->flags anybody cares
    about to new MAY_... ones and pass with the mask.
    * kill redundant gfs2_iop_permission()
    * sanitize ecryptfs_permission()
    * fix remaining places where ->permission() instances might barf on new
    MAY_... found in mask.

    The obvious next target in that direction is permission(9)

    folded fix for nfs_permission() breakage from Miklos Szeredi

  • 3bd858ab1   Introduce is_owner_or_cap() to wrap CAP_FOWNER use with fsuid check ... Browse Code »

    Introduce is_owner_or_cap() macro in fs.h, and convert over relevant
    users to it. This is done because we want to avoid bugs in the future
    where we check for only effective fsuid of the current task against a
    file's owning uid, without simultaneously checking for CAP_FOWNER as
    well, thus violating its semantics.
    [ XFS uses special macros and structures, and in general looked ...
    untouchable, so we leave it alone -- but it has been looked over. ]

    The (current->fsuid != inode->i_uid) check in generic_permission() and
    exec_permission_lite() is left alone, because those operations are
    covered by CAP_DAC_OVERRIDE and CAP_DAC_READ_SEARCH. Similarly operations
    falling under the purview of CAP_CHOWN and CAP_LEASE are also left alone.

  • dfa08592c   [PATCH] Fix two ext[23] uninitialized warnings ... Browse Code »

    There is a code path that passed size to ext2_xattr_set
    (ext3_xattr_set_handle) before initializing it. The callees don't use the
    value in that case, but gcc cannot tell. Always initialize size to get rid
    of the warnings.

  • 1da177e4c   Linux-2.6.12-rc2 ... Browse Code »

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
