New Revision: 262319
URL: http://svnweb.freebsd.org/changeset/base/262319

Log:
  MFC r261618:
  
  In g_eli_crypto_hmac_init(), zero out after using the ipad buffer,
  k_ipad.
  
  Note that the two consumers in geli(4) are not affected by this
  issue because the way the code is constructed and as such, we
  believe there is no security impact with or without this change
  with geli(4)'s usage.
