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 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.
