txt: perform per-domain (and frametable and xenheap) MAC on entry into
S3 and verification on resume. The MAC algorithm is called VMAC and was developed by Ted Krovetz and Wei Dai (more details are in the files). It is based on a universal hash function. The universal hash is passed through a pseudo-random function, implemented using AES. More details can be found at http://fastcrypto.org/vmac/. = The AES code comes from the OpenBSD implementation (which is derived from the implementation referenced in VMAC site). As Xen does not have a good source of entropy to generate its own key (for the keyed hash), it uses the key that tboot passes in. Although the code attempts to MAC all of a domain's pages (code/data, VT-d tables) based on its s3_integrity flag, some of a domain's memory may always be MAC'ed, e.g. shadow page tables. Only xenheap pages that are in use are MAC'ed. We believe that the memory MAC'ed by the Xen code and the ranges passed to tboot to MAC cover all of the memory whose integrity needs to be protected on S3. Any suggestions or ranges that we missed are welcome. Signed-off-by: Shane Wang <shane.wang@intel.com> Signed-off-by: Joseph Cihula <joseph.cihula@intel.com>

+ * Given msg m (mbytes in length) and nonce buffer n
+ * this function returns a tag as its output. The tag is returned as
+ * a number. When VMAC_TAG_LEN == 64, the 'return'ed integer is the tag,
+ * and *tagl is meaningless. When VMAC_TAG_LEN == 128 the tag is the
+ * number y * 2^64 + *tagl where y is the function's return value.
+ * If you want to consider tags to be strings, then you must do so with
+ * an agreed upon endian orientation for interoperability, and convert
+ * the results appropriately. VHASH hashes m without creating any tag.
+ * Consecutive substrings forming a prefix of a message may be passed
+ * to vhash_update, with vhash or vmac being called with the remainder
+ * to produce the output.
+ *
+ * Requirements:
+ * - On 32-bit architectures with SSE2 instructions, ctx and m MUST be
+ * begin on 16-byte memory boundaries.
+ * - m MUST be your message followed by zeroes to the nearest 16-byte
+ * boundary. If m is a length multiple of 16 bytes, then it is already
+ * at a 16-byte boundary and needs no padding. mbytes should be your
+ * message length without any padding.
+ * - The first bit of the nonce buffer n must be 0. An i byte nonce, is made
+ * as the first 16-i bytes of n being zero, and the final i the nonce.
+ * - vhash_update MUST have mbytes be a positive multiple of VMAC_NHBYTES
