      Subject: [PATCH] Smack: mmap controls for library containment · 7898e1f8
      Casey Schaufler 提交于
        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 提交于
      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]
