New Revision: 308829
URL: https://svnweb.freebsd.org/changeset/base/308829

Log:
  Create projects/ipsec.
  
  The main goals are:
  * rework locking to make IPsec code more friendly for concurrent processing;
  * make lookups in SADB/SPDB faster;
  * revise PFKEY implementation, remove stale code, make it closer to RFC;
  * implement IPsec VTI (virtual tunneling interface);
  * make IPsec code loadable as kernel module.
  
  Part of these tasks already done, but merging code in one commit is hard
  to review and document. So, I will try to split it in many patches. Also,
  this probably will lead to new changes/improvements that I will rethink
  in process.
