  • 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:

    The CONFIG_EXPERIMENTAL config item has not carried much meaning for a
    while now and is almost always enabled by default. As agreed during the
    Linux kernel summit, remove it from any "depends on" lines in Kconfigs.

    Make the 9P_FS kconfig options subordinate to the 9P_FS kconfig symbol
    in the menu presentation instead of them all being at the same level.

  • 60e78d2c9   9p: Add fscache support to 9p ... Browse Code »

    This patch adds a persistent, read-only caching facility for
    9p clients using the FS-Cache caching backend.

    When the fscache facility is enabled, each inode is associated
    with a corresponding vcookie which is an index into the FS-Cache
    indexing tree. The FS-Cache indexing tree is indexed at 3 levels:
    - session object associated with each mount.
    - inode/vcookie
    - actual data (pages)

    A cache tag is chosen randomly for each session. These tags can
    be read off /sys/fs/9p/caches and can be passed as a mount-time
    parameter to re-attach to the specified caching session.
