      [PATCH] USB: fix usblp.c · 5baa19b3
      Paulo Marques authored
      The line that IMHO triggers the bug is this:
      
      "writecount += usblp->writeurb->transfer_buffer_length;"
      
      It uses "usblp->writeurb->transfer_buffer_length" before initializing it,
      assuming that it will be zero on the first run. If it is not zero, but instead
      random *negative* garbage from memory, the loop will start printing endless data
      from user-space data.

      Update periodic schedule scanning
      	- fix shutdown sometimes-hangs (Bernd Porr)
      	- resolve the "whole frame at once" FIXME
      	- try harder to avoid rescanning
      	- don't delegate interrupt qh handling to a buggy helper routine
      	- describe more of the relevant iso tuning parameters
      
      One-liners:
      	- URB_NO_INTERRUPT hint affects ISO
      	- show correct data toggle in sysfs debug files
      	- FIXME is resolved by Linus' 20msec delay

      [PATCH] remove __ide_dma_count() and ide_hwif_t->ide_dma_count · 22e84a6b
      Bartlomiej Zolnierkiewicz authored
      ->ide_dma_count() was introduced in kernel 2.5.35 and was meant to add support
      for host FIFO counters (for VDMA), but is only a wrapper for ->ide_dma_begin()
      (even for siimage.c b/c SIIMAGE_VIRTUAL_DMAPIO is undefined).
      
      Moreover it should be possible to add VDMA code directly to ->ide_dma_begin().

      [PATCH] ide-tape: warn about soon to be removed OnStream support · 1e99d97a
      Bartlomiej Zolnierkiewicz authored
      I see only pros of removing OnStream support:
       - SCSI osst.c driver is actively maintained by Willem Riede <wrlk@riede.org>
       - there is no functionality loss (OnStream IDE drives don't support DSC)
       - ide-tape.c driver is too ugly & complicated even without OnStream support
       - long term benefits (2.7.x plans on unifying storage drivers)

      Andrew Morton authored
      From: Stephen Smalley <sds@epoch.ncsc.mil>
      
      This patch changes the mode bits on the selinuxfs enforce node so that
      non-root processes can read it.  This is necessary to allow non-root
      userspace policy enforcers to check the enforcing flag upon a permission
      failure as well.  A process must still have the appropriate SELinux
      permission in order to read the node.

      [PATCH] SELinux: context mount support - SELinux changes. · 0ce03642
      Andrew Morton authored
      From: James Morris <jmorris@redhat.com>
      
      This patch implements context mount support within SELinux.
      
      Three new mount options are provided:
      
      context=%s
        Label the entire filesystem with the specified security context during
        mount and change the labeling behavior to 'mountpoint labeling'.  The
        /proc/self/attr/fscreate attribute will be ignored for file creation on
        the filesystem, although policy-specified transitions will still work
        normally.  This also sets the aggregate filesystem security context.
      
      fscontext=%s
        Set the label of the aggregate filesystem to the specified security
        context, so that SELinux policy controls over the filesystem itself may
        be reinstated.  Only works for filesystems without EA labeling support,
        and is not valid if 'context' has been specified.
      
      defcontext=%s
        Set the default security context for files created in this filesystem to
        the specified security context (as opposed to the current global default).
        Only works for filesystems without EA labeling support, and is not
        valid if 'context' has been specified.
      
      To set the context or fscontext options, the security policy must specify
      appropriate permissions for the filesystem relabelfrom and filesystem
      relabelto controls.  For the defcontext option, the filesystem relablefrom
      and filesystem assoicate controls are invoked.
      
      The security mount options are parsed out and stripped from the normal
      mount option data so that no normal filesystems need to be aware of them.
      
      Filesystems with binary mount option data (e.g. NFS, SMBFS, AFS, Coda)
      need to be handled as special cases: only NFS is supprted at this stage
      per the previous patch.

      [PATCH] SELinux: context mount support - NFS · 79352ac6
      Andrew Morton authored
      From: James Morris <jmorris@redhat.com>
      
      This patch modifies the kernel's NFS mount data structure to include SELinux
      context mount data.  It allows NFS fileystems to be labeled on a
      per-mountpoint basis, and should not affect existing versions of userspace
      mount.
      
      (A patch to the userspace mount code is available at
      http://people.redhat.com/jmorris/selinux/context_mounts/)

      [PATCH] SELinux: context mount support - LSM/FS · 86d3ef68
      Andrew Morton authored
      From: James Morris <jmorris@redhat.com>
      
      This series of patches adds support for SELinux 'context mounts', which
      allows filesystems to be assigned security context information at mount time.
       For example, some filesystems do not support extended attributes (e.g.  NFS,
      vfat), and this feature allows security contexts to be assigned to them on a
      per-mountpoint basis.  It is also useful when the existing labeling on a
      filesystem is untrusted or unwanted for some reason (e.g.  removable media),
      and needs to be overridden with a safe default.
      
      The first patch below consists of infrastructure changes to the kernel:
      
      - A new LSM hook has been added, sb_copy_data, which allows the security
        module to copy security-specific mount data once the superblock has been
        setup by the filesystem.
      
      - The sb_kern_mount hook has been modified to take this security data as a
        parameter, and would typically be used at that point to configure the
        security parameters of the filesystem being mounted.
      
      - Allocation and freeing of the security data has been implemented in the
        core fs code as it is cleaner than trying to do it purely via LSM hooks,
        and should make maintenance easier.  This code will be compiled away if LSM
        is not enabled.

      [PATCH] radeonfb: limit ioremap size & debug output · f2d07c25
      Benjamin Herrenschmidt authored
      This adds a limit on how much of the framebuffer is ioremap'ed by
      radeonfb, thus enabling it to work with 128Mb VRAM or more on an x86
      with 900Mb of lowmem in the linear mapping.
      
      It also adds a significant amount of debug messages and adds a CONFIG
      option to enable the debugging output, that should help with diagnosing
      new problems. Among others, it dumps the connector info as I understand
      them (so far, they give "strange" informations on laptops, I need more
      data on more various laptops to see if there's a pattern I can really use
      to figure out on which connector the LVDS is)
      
      Regarding the "lid closed at boot", ultimately, we may want to default
      to the VGA output in those cases, though I'm not sure what logic to use
      here. Maybe we could standardize some way for the platform to provide
      this "environment" information to the driver, but i wouldn't rely on it.
      
      More reliably, if we can find out that there is an LVDS output, and
      LVDS is disabled, just ignore the flat panel...
      
      We could assume any mobility chip has LVDS, which is true, but that would
      still cause a problem for laptops with an additional DVI output (only
      Macs so far afaik).
