      netlabel: shorter names for the NetLabel catmap funcs/structs · 4fbe63d1
      Paul Moore authored
      Historically the NetLabel LSM secattr catmap functions and data
      structures have had very long names which makes a mess of the NetLabel
      code and anyone who uses NetLabel.  This patch renames the catmap
      functions and structures from "*_secattr_catmap_*" to just "*_catmap_*"
      which improves things greatly.
      
      There are no substantial code or logic changes in this patch.

      netlabel: fix the catmap walking functions · d960a618
      Paul Moore authored
      The two NetLabel LSM secattr catmap walk functions didn't handle
      certain edge conditions correctly, causing incorrect security labels
      to be generated in some cases.  This patch corrects these problems and
      converts the functions to use the new _netlbl_secattr_catmap_getnode()
      function in order to reduce the amount of repeated code.

      netlabel: fix the horribly broken catmap functions · 4b8feff2
      Paul Moore authored
      The NetLabel secattr catmap functions, and the SELinux import/export
      glue routines, were broken in many horrible ways and the SELinux glue
      code fiddled with the NetLabel catmap structures in ways that we
      probably shouldn't allow.  At some point this "worked", but that was
      likely due to a bit of dumb luck and sub-par testing (both inflicted
      by yours truly).  This patch corrects these problems by basically
      gutting the code in favor of something less obtuse and restoring the
      NetLabel abstractions in the SELinux catmap glue code.
      
      Everything is working now, and if it decides to break itself in the
      future this code will be much easier to debug than the code it
      replaces.
      
      One noteworthy side effect of the changes is that it is no longer
      necessary to allocate a NetLabel catmap before calling one of the
      NetLabel APIs to set a bit in the catmap.  NetLabel will automatically
      allocate the catmap nodes when needed, resulting in less allocations
      when the lowest bit is greater than 255 and less code in the LSMs.

      netlabel: fix a problem when setting bits below the previously lowest bit · 41c3bd20
      Paul Moore authored
      The NetLabel category (catmap) functions have a problem in that they
      assume categories will be set in an increasing manner, e.g. the next
      category set will always be larger than the last.  Unfortunately, this
      is not a valid assumption and could result in problems when attempting
      to set categories less than the startbit in the lowest catmap node.
      In some cases kernel panics and other nasties can result.
      
      This patch corrects the problem by checking for this and allocating a
      new catmap node instance and placing it at the front of the list.
