## DESCRIPTION

This VFS module is part of the samba 7 suite.

The `vfs_full_audit` VFS module records selected client operations to the system log using syslog 3.

`vfs_full_audit` is able to record the complete set of Samba VFS operations:

- chdir
- chflags
- chmod
- chown
- close
- closedir
- connect
- copy_chunk_send
- copy_chunk_recv
- disconnect
- disk_free
- fchmod
- fchown
- fget_nt_acl
- fgetxattr
- flistxattr
- fremovexattr
- fset_nt_acl
- fsetxattr
- fstat
- fsync
- ftruncate
- get_compression
- get_nt_acl
- get_quota
- get_shadow_copy_data
- getlock
- getwd
- getxattr
- kernel_flock
- link
- linux_setlease
- listxattr
- lock
- lseek
- lstat
- mkdir
- mknod
- open
- opendir
- pread
- pwrite
- read
- readdir
- readlink
- realpath
- removexattr
- rename
- rewinddir
- rmdir
- seekdir
- sendfile
- set_compression
- set_nt_acl
- set_quota
- setxattr
- snap_check_path
- snap_create
- snap_delete
- stat
- statvfs
- symlink
- sys_acl_delete_def_file
- sys_acl_get_fd
- sys_acl_get_file
- sys_acl_set_fd
- sys_acl_set_file
- telldir
- unlink
- utime
- write

In addition to these operations, `vfs_full_audit` recognizes the special operation names "all" and "none ", which refer to all the VFS operations and none of the VFS operations respectively.

`vfs_full_audit` records operations in fixed format consisting of fields separated by '|' characters. The format is:

    		smbd_audit: PREFIX|OPERATION|RESULT|FILE

The record fields are:

- `PREFIX` - the result of the full_audit:prefix string after variable substitutions

- `OPERATION` - the name of the VFS operation

- `RESULT` - whether the operation succeeded or failed

- `FILE` - the name of the file or directory the operation was performed on

This module is stackable.

## OPTIONS

full_audit:prefix = STRING

  Prepend audit messages with STRING. STRING is processed for standard substitution variables listed in smb.conf 5. The default prefix is "%u|%I".

full_audit:success = LIST

  LIST is a list of VFS operations that should be recorded if they succeed. Operations are specified using the names listed above. Operations can be unset by prefixing the names with "!". The default is none operations.

full_audit:failure = LIST

  LIST is a list of VFS operations that should be recorded if they failed. Operations are specified using the names listed above. Operations can be unset by prefixing the names with "!". The default is none operations.

full_audit:facility = FACILITY

  Log messages to the named syslog 3 facility.

full_audit:priority = PRIORITY

  Log messages with the named syslog 3 priority.

full_audit:syslog = true/false

  Log messages to syslog (default) or as a debug level 1 message.

full_audit:log_secdesc = true/false

  Log an sddl form of the security descriptor coming in when a client sets an acl. Defaults to false.

## EXAMPLES

Log file and directory open operations on the [records] share using the LOCAL7 facility and ALERT priority, including the username and IP address. Logging excludes the open VFS function on failures:

    	/data/records
    	full_audit
    	%u|%I
    	open opendir
    	all !open
    	LOCAL7
    	ALERT
