  • 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.

  • 99829b832   flag parameters: NONBLOCK in anon_inode_getfd ... Browse Code »

    Building on the previous change to anon_inode_getfd, this patch introduces
    support for handling of O_NONBLOCK in addition to the already supported
    O_CLOEXEC. Following patches will take advantage of this support. As can be
    seen, the additional support for supporting this functionality is minimal.

  • 7d9dbca34   flag parameters: anon_inode_getfd extension ... Browse Code »

    This patch just extends the anon_inode_getfd interface to take an additional
    parameter with a flag value. The flag value is passed on to
    get_unused_fd_flags in anticipation for a use with the O_CLOEXEC flag.

    No actual semantic changes here, the changed callers all pass 0 for now.

  • 2030a42ce   [PATCH] sanitize anon_inode_getfd() ... Browse Code »

    a) none of the callers even looks at inode or file returned by anon_inode_getfd()
    b) any caller that would try to look at those would be racy, since by the time
    it returns we might have raced with close() from another thread and that
    file would be pining for fjords.

  • 430e285e0   [PATCH] fix up new filp allocators ... Browse Code »

    Some new uses of get_empty_filp() have crept in; switched
    to alloc_file() to make sure that pieces of initialization
    won't be missing.

    We really need to kill get_empty_filp().

  • 96fdc72dd   anon-inodes use open coded atomic_inc for the shared inode ... Browse Code »

    Since we know the shared inode count is always >0, we can avoid igrab()
    and use an open coded atomic_inc().

    This also fixes a bug noticed by Yan Zheng : were checking
    for an IS_ERR() return from igrab(), but it actually returns NULL on error.

  • 5dc8bf813   signal/timer/event fds: anonymous inode source ... Browse Code »

    This patch add an anonymous inode source, to be used for files that need
    and inode only in order to create a file*. We do not care of having an
    inode for each file, and we do not even care of having different names in
    the associated dentries (dentry names will be same for classes of file*).
    This allow code reuse, and will be used by epoll, signalfd and timerfd
    (and whatever else there'll be).
