  • 31051c85b   fs: Give dentry to inode_change_ok() instead of inode ... Browse Code »

    inode_change_ok() will be resposible for clearing capabilities and IMA
    extended attributes and as such will need dentry. Give it as an argument
    to inode_change_ok() instead of an inode. Also rename inode_change_ok()
    to setattr_prepare() to better relect that it does also some
    modifications in addition to checks.

    Pull vfs updates from Al Viro:
    "Assorted cleanups and fixes.

    Probably the most interesting part long-term is ->d_init() - that will
    have a bunch of followups in (at least) ceph and lustre, but we'll
    need to sort the barrier-related rules before it can get used for
    really non-trivial stuff.

    Another fun thing is the merge of ->d_iput() callers (dentry_iput()
    and dentry_unlink_inode()) and a bunch of ->d_compare() ones (all
    except the one in __d_lookup_lru())"

  • 6b2553918   replace ->follow_link() with new method that could stay in RCU mode ... Browse Code »

    new method: ->get_link(); replacement of ->follow_link(). The differences
    are:
    * inode and dentry are passed separately
    * might be called both in RCU and non-RCU mode;
    the former is indicated by passing it a NULL dentry.
    * when called that way it isn't allowed to block
    and should return ERR_PTR(-ECHILD) if it needs to be called
    in non-RCU mode.

    It's a flagday change - the old method is gone, all in-tree instances
    converted. Conversion isn't hard; said that, so far very few instances
    do not immediately bail out when called in RCU mode. That'll change
    in the next commits.

    a) instead of storing the symlink body (via nd_set_link()) and returning
    an opaque pointer later passed to ->put_link(), ->follow_link() _stores_
    that opaque pointer (into void * passed by address by caller) and returns
    the symlink body. Returning ERR_PTR() on error, NULL on jump (procfs magic
    symlinks) and pointer to symlink body for normal symlinks. Stored pointer
    is ignored in all cases except the last one.

    Storing NULL for opaque pointer (or not storing it at all) means no call
    of ->put_link().

    b) the body used to be passed to ->put_link() implicitly (via nameidata).
    Now only the opaque pointer is. In the cases when we used the symlink body
    to free stuff, ->follow_link() now should store it as opaque pointer in addition
    to returning it.

    We copy there a kmalloc'ed string and proceed to kfree that string immediately
    after that. Easier to just feed that string to nd_set_link() and _not_
    kfree it until ->put_link() (which becomes kfree_put_link() in that case).

    Pull vfs pile (part one) from Al Viro:
    "Assorted stuff - cleaning namei.c up a bit, fixing ->d_name/->d_parent
    locking violations, etc.

    The most visible changes here are death of FS_REVAL_DOT (replaced with
    "has ->d_weak_revalidate()") and a new helper getting from struct file
    to inode. Some bits of preparation to xattr method interface changes.

    Misc patches by various people sent this cycle *and* ocfs2 fixes from
    several cycles ago that should've been upstream right then.

    Pull user namespace and namespace infrastructure changes from Eric W Biederman:
    "This set of changes starts with a few small enhnacements to the user
    namespace. reboot support, allowing more arbitrary mappings, and
    support for mounting devpts, ramfs, tmpfs, and mqueuefs as just the
    user namespace root.

    I do my best to document that if you care about limiting your
    unprivileged users that when you have the user namespace support
    enabled you will need to enable memory control groups.

    There is a minor bug fix to prevent overflowing the stack if someone
    creates way too many user namespaces.

    The bulk of the changes are a continuation of the kuid/kgid push down
    work through the filesystems. These changes make using uids and gids
    typesafe which ensures that these filesystems are safe to use when
    multiple user namespaces are in use. The filesystems converted for
    3.9 are ceph, 9p, afs, ocfs2, gfs2, ncpfs, nfs, nfsd, and cifs. The
    changes for these filesystems were a little more involved so I split
    the changes into smaller hopefully obviously correct changes.

    XFS is the only filesystem that remains. I was hoping I could get
    that in this release so that user namespace support would be enabled
    with an allyesconfig or an allmodconfig but it looks like the xfs
    changes need another couple of days before it they are ready."
