25 /*
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
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|.
42 * smbd_audit: nobody|192.168.234.1|open|fail (File not found)|r|x.txt
43 *
44 * where "nobody" is the connected username and "192.168.234.1" is the
45 * client's IP address.
46 *
47 * Options:
48 *
49 * prefix: A macro expansion template prepended to the syslog entry.
50 *
51 * success: A list of VFS operations for which a successful completion should
52 * be logged. Defaults to no logging at all. The special operation "all" logs
53 * - you guessed it - everything.
54 *
55 * failure: A list of VFS operations for which failure to complete should be
56 * logged. Defaults to logging everything.
