  26  * This module implements parseable logging for all Samba VFS operations.
  27  *
  28  * You use it as follows:
  29  *
  30  * [tmp]
  31  * path = /tmp
  32  * vfs objects = full_audit
  33  * full_audit:prefix = %u|%I
  34  * full_audit:success = open opendir create_file
  35  * full_audit:failure = all
  36  *
  37  * vfs op can be "all" which means log all operations.
  38  * vfs op can be "none" which means no logging.
  39  *
  40  * This leads to syslog entries of the form:
  41  * smbd_audit: nobody|192.168.234.1|opendir|ok|/tmp
  42  * smbd_audit: nobody|192.168.234.1|create_file|fail (No such file or directory)|0x1|file|open|/ts/doesNotExist
  43  * smbd_audit: nobody|192.168.234.1|open|ok|w|/tmp/file.txt
  44  * smbd_audit: nobody|192.168.234.1|create_file|ok|0x3|file|open|/tmp/file.txt
  45  *
  46  * where "nobody" is the connected username and "192.168.234.1" is the
  47  * client's IP address.
  48  *
  49  * Options:
  50  *
  51  * prefix: A macro expansion template prepended to the syslog entry.
  52  *
  53  * success: A list of VFS operations for which a successful completion should
  54  * be logged. Defaults to no logging at all. The special operation "all" logs
  55  * - you guessed it - everything.
  56  *
  57  * failure: A list of VFS operations for which failure to complete should be
  58  * logged. Defaults to logging everything.
