  • e409de992   9p: xattr simplifications ... Browse Code »

    Now that the xattr handler is passed to the xattr handler operations, we
    can use the same get and set operations for the user, trusted, and security
    xattr namespaces. In those namespaces, we can access the full attribute
    name by "reattaching" the name prefix the vfs has skipped for us. Add a
    xattr_full_name helper to make this obvious in the code.

    For the "system.posix_acl_access" and "system.posix_acl_default"
    attributes, handler->prefix is the full attribute name; the suffix is the
    empty string.

  • f15844e07   9P: fix return value in v9fs_fid_xattr_set ... Browse Code »

    v9fs_fid_xattr_set is supposed to return 0 on success.

    This corrects the behaviour introduced in commit
    bdd5c28dcb8330b9074404cc92a0b83aae5606a
    "9p: fix return value in case in v9fs_fid_xattr_set()"

    (The function returns a negative error on error, as expected)

  • d9a738597   fs/9p: xattr: add trusted and security namespaces ... Browse Code »

    Allow requests for security.* and trusted.* xattr name spaces
    to pass through to server.

    The new files are 99% cut and paste from fs/9p/xattr_user.c with the
    namespaces changed. It has the intended effect in superficial testing.
    I do not know much detail about how these namespaces are used, but passing
    them through to the server, which can decide whether to handle them or not,
    seems reasonable.

    I want to support a use case where an ext4 file system is mounted via 9P,
    then re-exported via samba to windows clients in a cluster. Windows wants
    to store xattrs such as security.NTACL. This works when ext4 directly
    backs samba, but not when 9P is inserted. This use case is documented here:

  • 5d3851530   9p: Reduce object size with CONFIG_NET_9P_DEBUG ... Browse Code »

    Reduce object size by deduplicating formats.

    Use vsprintf extension %pV.
    Rename P9_DPRINTK uses to p9_debug, align arguments.
    Add function for _p9_debug and macro to add __func__.
    Add missing "\n"s to p9_debug uses.
    Remove embedded function names as p9_debug adds it.
    Remove P9_EPRINTK macro and convert use to pr_.
    Add and use pr_fmt and pr_.
