+ * descriptors:
+ *
+ * - Versions before 2013.1.13 reject security descriptors ending with an empty
+ * SACL (System Access Control List). This bug can be worked around either by
+ * moving the empty SACL earlier in the security descriptor or by removing the
+ * SACL entirely. The latter work-around is valid because an empty SACL is
+ * equivalent to a "null", or non-existent, SACL.
+ * - Versions up to and including 2013.1.13 reject security descriptors ending
+ * with an empty DACL (Discretionary Access Control List). This is very
+ * similar to the SACL bug and should be fixed in the next release after
+ * 2013.1.13. However, removing the DACL is not a valid workaround because
+ * this changes the meaning of the security descriptor--- an empty DACL allows
+ * no access, whereas a "null" DACL allows all access.
+ *
+ * If the security descriptor was fixed, this function returns an allocated
+ * buffer containing the fixed security descriptor, and its size is updated.
+ * Otherwise (or if no memory is available) the original descriptor is returned.
