NAME
vfs_full_audit - record Samba VFS operations in the system log
SYNOPSIS
vfs objects = full_audit
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
chmod_acl
chown
close
closedir
connect
copy_chunk_send
copy_chunk_recv
disconnect
disk_free
fchmod
fchmod_acl
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

sys_acl_delete_def_file
sys_acl_get_fd
sys_acl_get_file
sys_acl_set_fd

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:
o PREFIX - the result of the full_audit:prefix string after
variable substitutions
o OPERATION - the name of the VFS operation
o RESULT - whether the operation succeeded or failed
o 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 all 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 all 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:
[records]
path = /data/records
vfs objects = full_audit
full_audit:prefix = %u|%I
full_audit:success = open opendir
full_audit:failure = all !open
full_audit:facility = LOCAL7
full_audit:priority = ALERT
