  • A logical volume can map to just part of underlying physical volume.
    In this case, it must be treated like a partition.

  • Linux allows executing the SG_IO ioctl on a partition or LVM volume, and
    will pass the command to the underlying block device. This is
    well-known, but it is also a large security problem when (via Unix
    permissions, ACLs, SELinux or a combination thereof) a program or user
    needs to be granted access only to part of the disk.

    This patch lets partitions forward a small set of harmless ioctls;
    others are logged with printk so that we can see which ioctls are
    actually sent. In my tests only CDROM_GET_CAPABILITY actually occurred.
    Of course it was being sent to a (partition on a) hard disk, so it would
    have failed with ENOTTY and the patch isn't changing anything in
    practice. Still, I'm treating it specially to avoid spamming the logs.

    In principle, this restriction should include programs running with
    CAP_SYS_RAWIO. If for example I let a program access /dev/sda2 and
    /dev/sdb, it still should not be able to read/write outside the
    boundaries of /dev/sda2 independent of the capabilities. However, for
    now programs with CAP_SYS_RAWIO will still be allowed to send the
    ioctls. Their actions will still be logged.

    This patch does not affect the non-libata IDE driver. That driver
    however already tests for bd != bd->bd_contains before issuing some
    ioctl; it could be restricted further to forbid these ioctls even for
    programs running with CAP_SYS_ADMIN/CAP_SYS_RAWIO.

  • Introduce a wrapper around scsi_cmd_ioctl that takes a block device.

    The function will then be enhanced to detect partition block devices
    and, in that case, subject the ioctls to whitelisting.

  • The existing gpio_to_irq() implementation on sa1100 only translates
    validly for internal GPIOs. Since this sub-arch enables GPIOLIB
    support, this results in buggy translations for non-internal GPIOs.

    Get rid of the private gpio_to_irq() implementation, replacing it
    with the .to_irq method in the sa1100 gpio chip instead.

  • Newer nVidia cards with Optimus do not support/use the DSM switching functions.
    Instead, it require a DSM function to be called prior to bringing a device into
    D3 state. No other _DSM calls are necessary before/after enabling/disabling a
    device. Switching between discrete and integrated GPU is not supported by
    this Optimus _DSM call, therefore return on the switching method.

    To get around that issues we discard modes that doesn't fit. This is a temporary

    The big WARN() has nothing to do with the culprit - which is that
    the firmware was not loaded. So lets remove the WARN() from the TTM DMA code.

  • Andrew explains:

    - various misc stuff

    - Most of the rest of MM: memcg, threaded hugepages, others.

    - cpumask

    - kexec

    - kdump

    - some direct-io performance tweaking

    - radix-tree optimisations

    - new selftests code

    A note on this: often people will develop a new userspace-visible
    feature and will develop userspace code to exercise/test that
    feature. Then they merge the patch and the selftest code dies.
    Sometimes we paste it into the changelog. Sometimes the code gets
    thrown into Documentation/(!).

    This saddens me. So this patch creates a bare-bones framework which
    will henceforth allow me to ask people to include their test apps in
    the kernel tree so we can keep them alive. Then when people enhance
    or fix the feature, I can ask them to update the test app too.

    The infrastruture is terribly trivial at present - let's see how it
    evolves.

    - checkpoint/restart feature work.

    A note on this: this is a project by various mad Russians to perform
    c/r mainly from userspace, with various oddball helper code added
    into the kernel where the need is demonstrated.

    So rather than some large central lump of code, what we have is
    little bits and pieces popping up in various places which either
    expose something new or which permit something which is normally
    kernel-private to be modified.

    The overall project is an ongoing thing. I've judged that the size
    and scope of the thing means that we're more likely to be successful
    with it if we integrate the support into mainline piecemeal rather
    than allowing it all to develop out-of-tree.

    However I'm less confident than the developers that it will all
    eventually work! So what I'm asking them to do is to wrap each piece
    of new code inside CONFIG_CHECKPOINT_RESTORE. So if it all
    eventually comes to tears and the project as a whole fails, it should
    be a simple matter to go through and delete all trace of it.

    This lot pretty much wraps up the -rc1 merge for me.

  • If a platform device exists on the system, but ramoops fails to attach to
    it, the module parameters are overridden before ramoops can fall back and
    try to use passed module parameters. Move update to end of init routine.

  • Currently no udev events for memory hotplug "online" and "offline" are
    generated:

    # udevadm monitor
    # echo offline > /sys/devices/system/memory/memory4/state
    ==> No event

    When kdump is loaded, kexec detects the current memory configuration and
    stores it in the pre-allocated ELF core header. Therefore, for kdump it
    is necessary to reload the kdump kernel with kexec when the memory
    configuration changes (e.g. for online/offline hotplug memory).

    In order to do this automatically, udev rules should be used. This kernel
    patch adds udev events for "online" and "offline". Together with this
    kernel patch, the following udev rules for online/offline have to be added
    to "/etc/udev/rules.d/98-kexec.rules":

    SUBSYSTEM=="memory", ACTION=="online", PROGRAM="/etc/init.d/kdump restart"
    SUBSYSTEM=="memory", ACTION=="offline", PROGRAM="/etc/init.d/kdump restart"

  • KMSG_DUMP_KEXEC is useless because we already save kernel messages inside
    /proc/vmcore, and it is unsafe to allow modules to do other stuffs in a
    crash dump scenario.
