  • Recent changes to kernel/module.c caused the following compile

    kernel/module.c: In function ‘show_taint’:
    kernel/module.c:1024:2: error: implicit declaration of function ‘module_flags_taint’ [-Werror=implicit-function-declaration]
    cc1: some warnings being treated as errors

    Correct this error by moving the definition of module_flags_taint
    outside of the #ifdef CONFIG_MODULE_UNLOAD section.

  • This reverts commit 274193224cdabd687d804a26e0150bb20f2dd52c.

    We have some problems related to selection of empty queues
    that need to be resolved, evidence so far points to the
    recursive merge logic making either being the cause or at
    least the accelerator for this. So revert it for now, until
    we figure this out.

    Main features:

    - Memory hotplug support.

    Usability improvements:
    - Show the origin of early allocations.
    - Report previously found leaks even if kmemleak has been disabled by
    some error.

  • 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.
