  • 5366dc9fd   eCryptfs: Swap dput() and mntput() ... Browse Code »

    ecryptfs_d_release() is doing a mntput before doing the dput. This patch
    moves the dput before the mntput.

    Thanks to Rajouri Jammu for reporting this.

  • 4ac913785   Embed a struct path into struct nameidata instead of nd->{dentry,mnt} ... Browse Code »

    This is the central patch of a cleanup series. In most cases there is no good
    reason why someone would want to use a dentry for itself. This series reflects
    that fact and embeds a struct path into nameidata.

    Together with the other patches of this series
    - it enforced the correct order of getting/releasing the reference count on
    pairs
    - it prepares the VFS for stacking support since it is essential to have a
    struct path in every place where the stack can be traversed
    - it reduces the overall code size:

    without patch series:
    text data bss dec hex filename
    5321639 858418 715768 6895825 6938d1 vmlinux

    with patch series:
    text data bss dec hex filename
    5320026 858418 715768 6894212 693284 vmlinux

    This patch:

    Switch from nd->{dentry,mnt} to nd->path.{dentry,mnt} everywhere.

  • b228b8e5b   [PATCH] eCryptfs: fix possible NULL ptr deref in ecryptfs_d_release() ... Browse Code »

    ecryptfs_d_release() first dereferences a pointer (via
    ecryptfs_dentry_to_lower()) and then afterwards checks to see if the
    pointer it just dereferenced is NULL (via ecryptfs_dentry_to_private()).

    This patch moves all of the work done on the dereferenced pointer inside a
    block governed by the condition that the pointer is non-NULL.

  • ae56fb163   [PATCH] eCryptfs: CIFS nlink fixes ... Browse Code »

    When CIFS is the lower filesystem, the old lower dentry needs to be explicitly
    dropped from inside eCryptfs to force a revalidate. In addition, when CIFS is
    the lower filesystem, the inode attributes need to be copied back up from the
    lower inode to the eCryptfs inode on an eCryptfs revalidate.

  • 237fead61   [PATCH] ecryptfs: fs/Makefile and fs/Kconfig ... Browse Code »

    eCryptfs is a stacked cryptographic filesystem for Linux. It is derived from
    Erez Zadok's Cryptfs, implemented through the FiST framework for generating
    stacked filesystems. eCryptfs extends Cryptfs to provide advanced key
    management and policy features. eCryptfs stores cryptographic metadata in the
    header of each file written, so that encrypted files can be copied between
    hosts; the file will be decryptable with the proper key, and there is no need
    to keep track of any additional information aside from what is already in the
    encrypted file itself.
