  • d8c76e6f4   [PATCH] r/o bind mount prepwork: inc_nlink() helper ... Browse Code »

    This is mostly included for parity with dec_nlink(), where we will have some
    more hooks. This one should stay pretty darn straightforward for now.

  • 9a53c3a78   [PATCH] r/o bind mounts: unlink: monitor i_nlink ... Browse Code »

    When a filesystem decrements i_nlink to zero, it means that a write must be
    performed in order to drop the inode from the filesystem.

    We're shortly going to have keep filesystems from being remounted r/o between
    the time that this i_nlink decrement and that write occurs.

    So, add a little helper function to do the decrements. We'll tie into it in a
    bit to note when i_nlink hits zero.

  • ba52de123   [PATCH] inode-diet: Eliminate i_blksize from the inode structure ... Browse Code »

    This eliminates the i_blksize field from struct inode. Filesystems that want
    to provide a per-inode st_blksize can do so by providing their own getattr
    routine instead of using the generic_fillattr() function.

    Note that some filesystems were providing pretty much random (and incorrect)
    values for i_blksize.

    * Rougly half of callers already do it by not checking return value
    * Code in drivers/acpi/osl.c does the following to be sure:

    (void)kmem_cache_destroy(cache);

    * Those who check it printk something, however, slab_error already printed
    the name of failed cache.
    * XFS BUGs on failed kmem_cache_destroy which is not the decision
    low-level filesystem driver should make. Converted to ignore.

  • 75e1fcc0b   [PATCH] vfs: add lock owner argument to flush operation ... Browse Code »

    Pass the POSIX lock owner ID to the flush operation.

    This is useful for filesystems which don't want to store any locking state
    in inode->i_flock but want to handle locking/unlocking POSIX locks
    internally. FUSE is one such filesystem but I think it possible that some
    network filesystems would need this also.

    Also add a flag to indicate that a POSIX locking request was generated by
    close(), so filesystems using the above feature won't send an extra locking
    request in this case.

  • 454e2398b   [PATCH] VFS: Permit filesystem to override root dentry on mount ... Browse Code »

    Extend the get_sb() filesystem operation to take an extra argument that
    permits the VFS to pass in the target vfsmount that defines the mountpoint.

    The filesystem is then required to manually set the superblock and root dentry
    pointers. For most filesystems, this should be done with simple_set_mnt()
    which will set the superblock pointer and then set the root dentry to the
    superblock's s_root (as per the old default behaviour).

    The get_sb() op now returns an integer as there's now no need to return the
    superblock pointer.

    This patch permits a superblock to be implicitly shared amongst several mount
    points, such as can be done with NFS to avoid potential inode aliasing. In
    such a case, simple_set_mnt() would not be called, and instead the mnt_root
    and mnt_sb would be set directly.

    The patch also makes the following changes:

    (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount
    pointer argument and return an integer, so most filesystems have to change
    very little.

    (*) If one of the convenience function is not used, then get_sb() should
    normally call simple_set_mnt() to instantiate the vfsmount. This will
    always return 0, and so can be tail-called from get_sb().

    (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the
    dcache upon superblock destruction rather than shrink_dcache_anon().

    This is required because the superblock may now have multiple trees that
    aren't actually bound to s_root, but that still need to be cleaned up. The
    currently called functions assume that the whole tree is rooted at s_root,
    and that anonymous dentries are not the roots of trees which results in
    dentries being left unculled.

    However, with the way NFS superblock sharing are currently set to be
    implemented, these assumptions are violated: the root of the filesystem is
    simply a dummy dentry and inode (the real inode for '/' may well be
    inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries
    with child trees.

    [*] Anonymous until discovered from another tree.

    (*) The documentation has been adjusted, including the additional bit of
    changing ext2_* into foo_* in the documentation.

  • 20ca73bc7   [PATCH] Audit of POSIX Message Queue Syscalls v.2 ... Browse Code »

    This patch adds audit support to POSIX message queues. It applies cleanly to
    the lspp.b15 branch of Al Viro's git tree. There are new auxiliary data
    structures, and collection and emission routines in kernel/auditsc.c. New hooks
    in ipc/mqueue.c collect arguments from the syscalls.

    I tested the patch by building the examples from the POSIX MQ library tarball.
    Build them -lrt, not against the old MQ library in the tarball. Here's the URL:
    http://www.geocities.com/wronski12/posix_ipc/libmqueue-4.41.tar.gz
    Do auditctl -a exit,always -S for mq_open, mq_timedsend, mq_timedreceive,
    mq_notify, mq_getsetattr. mq_unlink has no new hooks. Please see the
    corresponding userspace patch to get correct output from auditd for the new
    record types.

  • a70ea994a   [NETLINK]: Fix a severe bug ... Browse Code »

    netlink overrun was broken while improvement of netlink.
    Destination socket is used in the place where it was meant to be source socket,
    so that now overrun is never sent to user netlink sockets, when it should be,
    and it even can be set on kernel socket, which results in complete deadlock
    of rtnetlink.

    Suggested fix is to restore status quo passing source socket as additional
    argument to netlink_attachskb().

    A little explanation: overrun is set on a socket, when it failed
    to receive some message and sender of this messages does not or even
    have no way to handle this error. This happens in two cases:
    1. when kernel sends something. Kernel never retransmits and cannot
    wait for buffer space.
    2. when user sends a broadcast and the message was not delivered
    to some recipients.

  • 7c7dce920   [PATCH] Fix double decrement of mqueue_mnt->mnt_count in sys_mq_open ... Browse Code »

    Fixed the refcounting on failure exits in sys_mq_open() and
    cleaned the logics up. Rules are actually pretty simple - dentry_open()
    expects vfsmount and dentry to be pinned down and it either transfers
    them into created struct file or drops them. Old code had been very
    confused in that area - if dentry_open() had failed either in do_open()
    or do_create(), we ended up dentry and mqueue_mnt dropped twice, once
    by dentry_open() cleanup and then by sys_mq_open().

    Fix consists of making the rules for do_create() and do_open()
    same as for dentry_open() and updating the sys_mq_open() accordingly;
    that actually leads to more straightforward code and less work on
    normal path.

    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!
