  • 2f6f0654a   userns: Convert vfs posix_acl support to use kuids and kgids ... Browse Code »

    - In setxattr if we are setting a posix acl convert uids and gids from
    the current user namespace into the initial user namespace, before
    the xattrs are passed to the underlying filesystem.

    Untranslatable uids and gids are represented as -1 which
    posix_acl_from_xattr will represent as INVALID_UID or INVALID_GID.
    posix_acl_valid will fail if an acl from userspace has any
    INVALID_UID or INVALID_GID values. In net this guarantees that
    untranslatable posix acls will not be stored by filesystems.

    - In getxattr if we are reading a posix acl convert uids and gids from
    the initial user namespace into the current user namespace.

    Uids and gids that can not be tranlsated into the current user namespace
    will be represented as -1.

    - Replace e_id in struct posix_acl_entry with an anymouns union of
    e_uid and e_gid. For the short term retain the e_id field
    until all of the users are converted.

    - Don't set struct posix_acl.e_id in the cases where the acl type
    does not use e_id. Greatly reducing the use of ACL_UNDEFINED_ID.

    - Rework the ordering checks in posix_acl_valid so that I use kuid_t
    and kgid_t types throughout the code, and so that I don't need
    arithmetic on uid and gid types.

  • f61f6da0d   NFS: Prevent memory allocation failure in nfsacl_encode() ... Browse Code »

    nfsacl_encode() allocates memory in certain cases. This of course
    is not guaranteed to work.

    Since commit 9f06c719 "SUNRPC: New xdr_streams XDR encoder API", the
    kernel's XDR encoders can't return a result indicating possibly a
    failure, so a memory allocation failure in nfsacl_encode() has become
    fatal (ie, the XDR code Oopses) in some cases.

    However, the allocated memory is a tiny fixed amount, on the order
    of 40-50 bytes. We can easily use a stack-allocated buffer for
    this, with only a wee bit of nose-holding.

  • da9592ede   CRED: Wrap task credential accesses in the filesystem subsystem ... Browse Code »

    Wrap access to task credentials so that they can be separated more easily from
    the task_struct during the introduction of COW creds.

    Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id().

    Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more
    sense to use RCU directly rather than a convenient wrapper; these will be
    addressed by later patches.

  • dd0fc66fb   [PATCH] gfp flags annotations - part 1 ... Browse Code »

    - added typedef unsigned int __nocast gfp_t;

    - replaced __nocast uses for gfp flags with gfp_t - it gives exactly
    the same warnings as far as sparse is concerned, doesn't change
    generated code (from gcc point of view we replaced unsigned int with
    typedef) and documents what's going on far better.

    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!
