  1. PCAP_LOOP_SLEEP bug fix to 1/10th of a second

    committed
    [server] Updated PCAP_LOOP_SLEEP default to 1/10th of a second (in
    microseconds).  This was supposed to be the default anyway, but C
    Anthony Risinger reported a bug where fwknopd was consuming more
    resources than necessary, and the cause was PCAP_LOOP_SLEEP set by
    default to 1/100th of a second - this has been fixed.

  1. Bug fix for multi-stanza key use and replay attack detection

    committed
    This commit fixes a bug where the same encryption key used for two stanzas in
    the access.conf file would result in access requests that matched the second
    stanza to always be treated as a replay attack.  This has been fixed for
    the fwknop-2.0.1 release, and was reported by Andy Rowland.  Now the fwknopd
    server computes the SHA256 digest of raw incoming payload data before
    decryption, and compares this against all previous hashes.  Previous to this
    commit, fwknopd would add a new hash to the replay digest list right after
    the first access.conf stanza match, so when SPA packet data matched the
    second access.conf stanza a matching replay digest would already be there.
