New revision: 285249
URL: https://svnweb.freebsd.org/changeset/base/285249

Log:
  MFC r273489 (cperciva):
   Populate the GELI passphrase cache with the kern.geom.eli.passphrase
   variable (if any) provided in the boot environment.  Unset it from
   the kernel environment after doing this, so that the passphrase is
   no longer present in kernel memory once we enter userland.

   This will make it possible to provide a GELI passphrase via the boot
   loader.
