  27  * This module implements parseable logging for all Samba VFS operations.
  28  *
  29  * You use it as follows:
  30  *
  31  * [tmp]
  32  * path = /tmp
  33  * vfs objects = full_audit
  34  * full_audit:prefix = %u|%I
  35  * full_audit:success = open opendir
  36  * full_audit:failure = all
  37  *
  38  * vfs op can be "all" which means log all operations.
  39  * vfs op can be "none" which means no logging.
  40  *
  41  * This leads to syslog entries of the form:
  42  * smbd_audit: nobody|192.168.234.1|opendir|ok|.
  43  * smbd_audit: nobody|192.168.234.1|open|fail (File not found)|r|x.txt
  44  *
  45  * where "nobody" is the connected username and "192.168.234.1" is the
  46  * client's IP address.
  47  *
  48  * Options:
  49  *
  50  * prefix: A macro expansion template prepended to the syslog entry.
  51  *
  52  * success: A list of VFS operations for which a successful completion should
  53  * be logged. Defaults to no logging at all. The special operation "all" logs
  54  * - you guessed it - everything.
  55  *
  56  * failure: A list of VFS operations for which failure to complete should be
  57  * logged. Defaults to logging everything.
