      security: remove unused security_sysctl hook · 4916ca40
      Lucian Adrian Grijincu authored
      
      
      The only user for this hook was selinux. sysctl routes every call
      through /proc/sys/. Selinux and other security modules use the file
      system checks for sysctl too, so no need for this hook any more.

      security/selinux: fix /proc/sys/ labeling · 8e6c9693
      Lucian Adrian Grijincu authored
      This fixes an old (2007) selinux regression: filesystem labeling for
      /proc/sys returned
           -r--r--r-- unknown                          /proc/sys/fs/file-nr
      instead of
           -r--r--r-- system_u:object_r:sysctl_fs_t:s0 /proc/sys/fs/file-nr
      
      Events that lead to breaking of /proc/sys/ selinux labeling:
      
      1) sysctl was reimplemented to route all calls through /proc/sys/
      
          commit 77b14db5
          [PATCH] sysctl: reimplement the sysctl proc support
      
      2) proc_dir_entry was removed from ctl_table:
      
          commit 3fbfa981
          [PATCH] sysctl: remove the proc_dir_entry member for the sysctl tables
      
      3) selinux still walked the proc_dir_entry tree to apply
         labeling. Because ctl_tables don't have a proc_dir_entry, we did
         not label /proc/sys/ inodes any more. To achieve this the /proc/sys/
         inodes were marked private and private inodes were ignored by
         selinux.
      
          commit bbaca6c2
          [PATCH] selinux: enhance selinux to always ignore private inodes
      
          commit 86a71dbd
      
      
          [PATCH] sysctl: hide the sysctl proc inodes from selinux
      
      Access control checks have been done by means of a special sysctl hook
      that was called for read/write accesses to any /proc/sys/ entry.
      
      We don't have to do this because, instead of walking the
      proc_dir_entry tree we can walk the dentry tree (as done in this
      patch). With this patch:
      * we don't mark /proc/sys/ inodes as private
      * we don't need the sysclt security hook
      * we walk the dentry tree to find the path to the inode.
      
      We have to strip the PID in /proc/PID/ entries that have a
      proc_dir_entry because selinux does not know how to label paths like
      '/1/net/rpc/nfsd.fh' (and defaults to 'proc_t' labeling). Selinux does
      know of '/net/rpc/nfsd.fh' (and applies the 'sysctl_rpc_t' label).
      
      PID stripping from the path was done implicitly in the previous code
      because the proc_dir_entry tree had the root in '/net' in the example
      from above. The dentry tree has the root in '/1'.

      SELinux: Use dentry name in new object labeling · 652bb9b0
      Eric Paris authored
      
      
      Currently SELinux has rules which label new objects according to 3 criteria.
      The label of the process creating the object, the label of the parent
      directory, and the type of object (reg, dir, char, block, etc.)  This patch
      adds a 4th criteria, the dentry name, thus we can distinguish between
      creating a file in an etc_t directory called shadow and one called motd.
      
      There is no file globbing, regex parsing, or anything mystical.  Either the
      policy exactly (strcmp) matches the dentry name of the object or it doesn't.
      This patch has no changes from today if policy does not implement the new
      rules.

      fs/vfs/security: pass last path component to LSM on inode creation · 2a7dba39
      Eric Paris authored
      
      
      SELinux would like to implement a new labeling behavior of newly created
      inodes.  We currently label new inodes based on the parent and the creating
      process.  This new behavior would also take into account the name of the
      new object when deciding the new label.  This is not the (supposed) full path,
      just the last component of the path.
      
      This is very useful because creating /etc/shadow is different than creating
      /etc/passwd but the kernel hooks are unable to differentiate these
      operations.  We currently require that userspace realize it is doing some
      difficult operation like that and than userspace jumps through SELinux hoops
      to get things set up correctly.  This patch does not implement new
      behavior, that is obviously contained in a seperate SELinux patch, but it
      does pass the needed name down to the correct LSM hook.  If no such name
      exists it is fine to pass NULL.

      Subject: [PATCH] Smack: mmap controls for library containment · 7898e1f8
      Casey Schaufler authored
      
      
        In the embedded world there are often situations
        where libraries are updated from a variety of sources,
        for a variety of reasons, and with any number of
        security characteristics. These differences
        might include privilege required for a given library
        provided interface to function properly, as occurs
        from time to time in graphics libraries. There are
        also cases where it is important to limit use of
        libraries based on the provider of the library and
        the security aware application may make choices
        based on that criteria.
      
        These issues are addressed by providing an additional
        Smack label that may optionally be assigned to an object,
        the SMACK64MMAP attribute. An mmap operation is allowed
        if there is no such attribute.
      
        If there is a SMACK64MMAP attribute the mmap is permitted
        only if a subject with that label has all of the access
        permitted a subject with the current task label.
      
        Security aware applications may from time to time
        wish to reduce their "privilege" to avoid accidental use
        of privilege. One case where this arises is the
        environment in which multiple sources provide libraries
        to perform the same functions. An application may know
        that it should eschew services made available from a
        particular vendor, or of a particular version.
      
        In support of this a secondary list of Smack rules has
        been added that is local to the task. This list is
        consulted only in the case where the global list has
        approved access. It can only further restrict access.
        Unlike the global last, if no entry is found on the
        local list access is granted. An application can add
        entries to its own list by writing to /smack/load-self.
      
        The changes appear large as they involve refactoring
        the list handling to accomodate there being more
        than one rule list.

      I've no idea why this driver uses NULL for dma_unmap_single instead of
      the &spi->dev that is laying around just waiting to be used in that
      function - but it's an easy fix.
      
      Also replace this comment with a FIXME comment:
                      /* Do DMA mapping "early" for better error reporting and
                       * dcache use.  Note that if dma_unmap_single() ever starts
                       * to do real work on ARM, we'd need to clean up mappings
                       * for previous transfers on *ALL* exits of this loop...
                       */
      as the comment is not true - we do work in dma_unmap() functions,
      particularly on ARMv6 and above.  I've corrected the existing unmap
      functions but if any others are required they must be added ASAP.

      spi/imx: correct the test on platform_get_irq() return value · 73575938
      Richard Genoud authored
      
      
      The test "if (spi_imx->irq <= 0)" is not testing the IRQ value, but
      the return value of platform_get_irq().  As platform_get_irq() can
      return an error (-ENXIO) or the IRQ value it found, the test should be
      "if (spi_imx->irq < 0)"
      
      [grant.likely: Note: In general, Linux irq number 0 should also mean
      no irq, but arm still allows devices to be assigned 0, and the imx
      platform uses 0 for one of the spi devices, so this patch is needed
      for the device to work]

      Peter Zijlstra authored
      
      
      Function-scope statics are discouraged because they are
      easily overlooked and can cause subtle bugs/races due to
      their global (non-SMP safe) nature.
      
      Linus noticed that we did this for sched_param - at minimum
      make the const.

      One of the operands, buf, is incorrect, since it is stripped and the
      correct address for subsequent string comparing could change if
      leading white spaces, if any, are removed from buf.
      
      It is fixed by replacing buf with cmp.

      root_task_group is the leftover of USER_SCHED, now it's always
      same to init_task_group.
      But as Mike suggested, root_task_group is maybe the suitable name
      to keep for a tree.
      So in this patch:
        init_task_group      --> root_task_group
