2------------
Steve French3abb9272005-11-28 08:16:13 -08003Defer close of a file handle slightly if pending writes depend on that handle
Steve French23e7dd72005-10-20 13:44:56 -07004(this reduces the EBADF bad file handle errors that can be logged under heavy
Steve French3c50c612005-11-10 17:31:33 -08005stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
Steve French3abb9272005-11-28 08:16:13 -08006Fix SFU style symlinks and mknod needed for servers which do not support the
7CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
8dentries so files that the client sees as deleted but that later get created
9on the server will be recognized.

Steve French190fdeb2005-10-10 11:48:26 -070011Version 1.38
12------------
13Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
14to be smaller at first (but increasing) so large write performance performance
15over GigE is better. Do not hang thread on illegal byte range lock response
16from Windows (Windows can send an RFC1001 size which does not match smb size) by
17allowing an SMBs TCP length to be up to a few bytes longer than it should be.
18wsize and rsize can now be larger than negotiated buffer size if server
19supports large readx/writex, even when directio mount flag not specified.
20Write size will in many cases now be 16K instead of 4K which greatly helps
Steve French4ca9c192005-10-10 19:52:13 -070021file copy performance on lightly loaded networks. Fix oops in dnotify
Steve French1047abc2005-10-11 19:58:06 -070022when experimental config flag enabled. Make cifsFYI more granular.
Steve French190fdeb2005-10-10 11:48:26 -070023
Steve Frencheafe8702005-09-15 21:47:30 -070024Version 1.37
25------------
26Fix readdir caching when unlink removes file in current search buffer,
27and this is followed by a rewind search to just before the deleted entry.
Steve Frenche30dcf32005-09-20 20:49:16 -070028Do not attempt to set ctime unless atime and/or mtime change requested
Steve French20962432005-09-21 22:05:57 -070029(most servers throw it away anyway). Fix length check of received smbs
Steve French70ca7342005-09-22 16:32:06 -070030to be more accurate. Fix big endian problem with mapchars mount option,
31and with a field returned by statfs.
Steve Frencheafe8702005-09-15 21:47:30 -070032
Steve Frenchc46fa8a2005-08-18 20:49:57 -070033Version 1.36
34------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -070035Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
Steve French6b8edfe2005-08-23 20:26:03 -070036For these older servers, add option for passing netbios name of server in
Steve French16abbec2005-08-30 13:10:14 -070037on mount (servernetbiosname). Add suspend support for power management, to
38avoid cifsd thread preventing software suspend from working.
Steve Frenchc46fa8a2005-08-18 20:49:57 -070039Add mount option for disabling the default behavior of sending byte range lock
40requests to the server (necessary for certain applications which break with
41mandatory lock behavior such as Evolution), and also mount option for
42requesting case insensitive matching for path based requests (requesting
43case sensitive is the default).
44
Steve Frenchf4cfd692005-07-14 18:29:02 -050045Version 1.35
46------------
47Add writepage performance improvements. Fix path name conversions
48for long filenames on mounts which were done with "mapchars" mount option
Steve Frencha10faeb22005-08-22 21:38:31 -070049specified. Ensure multiplex ids do not collide. Fix case in which
50rmmod can oops if done soon after last unmount. Fix truncated
51search (readdir) output when resume filename was a long filename.
52Fix filename conversion when mapchars mount option was specified and
53filename was a long filename.
Steve Frenchf4cfd692005-07-14 18:29:02 -050054
Steve French11aa0142005-04-28 22:41:10 -070055Version 1.34
56------------
57Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
Steve French31ca3bc2005-04-28 22:41:11 -070058Do not oops if root user kills cifs oplock kernel thread or
59kills the cifsd thread (NB: killing the cifs kernel threads is not
60recommended, unmount and rmmod cifs will kill them when they are
Steve French68575472005-04-30 11:10:57 -070061no longer needed). Fix readdir to ASCII servers (ie older servers
Steve Frenchc0c3e8e2005-08-24 14:01:13 -070062which do not support Unicode) and also require asterisk.
Steve French3079ca62005-06-09 14:44:07 -070063Fix out of memory case in which data could be written one page
64off in the page cache.
Steve French11aa0142005-04-28 22:41:10 -070065
Steve French966ca922005-04-28 22:41:08 -070066Version 1.33
67------------
68Fix caching problem, in which readdir of directory containing a file
69which was cached could cause the file's time stamp to be updated
70without invalidating the readahead data (so we could get stale
71file data on the client for that file even as the server copy changed).
Steve Frenchcd634992005-04-28 22:41:10 -070072Cleanup response processing so cifsd can not loop when abnormally
73terminated.
Steve French966ca922005-04-28 22:41:08 -070074
75
Steve Frenchf654bac2005-04-28 22:41:04 -070076Version 1.32
Linus Torvalds1da177e2005-04-16 15:20:36 -070077------------
78Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
79transact response for an SMB request and search entry split across two frames.
Steve Frenchf654bac2005-04-28 22:41:04 -070080Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
81as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
82unless server explicitly claims to support them in CIFS Unix extensions
Steve Frenchad009ac2005-04-28 22:41:05 -070083POSIX ACL capability bit. Fix packet signing when multiuser mounting with
Steve Frenchcbe04762005-04-28 22:41:05 -070084different users from the same client to the same server. Fix oops in
Steve French6a0b4822005-04-28 22:41:05 -070085cifs_close. Add mount option for remapping reserved characters in
86filenames (also allow recognizing files with created by SFU which have any
Steve French737b7582005-04-28 22:41:06 -070087of these seven reserved characters, except backslash, to be recognized).
Steve French848f3fc2005-04-28 22:41:07 -070088Fix invalid transact2 message (we were sometimes trying to interpret
Steve French099a58f2005-04-28 22:41:07 -070089oplock breaks as SMB responses). Add ioctl for checking that the
90current uid matches the uid of the mounter (needed by umount.cifs).
91Reduce the number of large buffer allocations in cifs response processing
92(significantly reduces memory pressure under heavy stress with multiple
93processes accessing the same server at the same time).
Steve Frenchf654bac2005-04-28 22:41:04 -070094
95Version 1.31
96------------
Linus Torvalds1da177e2005-04-16 15:20:36 -070097Fix updates of DOS attributes and time fields so that files on NT4 servers
98do not get marked delete on close. Display sizes of cifs buffer pools in
99cifs stats. Fix oops in unmount when cifsd thread being killed by
100shutdown. Add generic readv/writev and aio support. Report inode numbers
101consistently in readdir and lookup (when serverino mount option is
102specified use the inode number that the server reports - for both lookup
103and readdir, otherwise by default the locally generated inode number is used
104for inodes created in either path since servers are not always able to
105provide unique inode numbers when exporting multiple volumes from under one
106sharename).
107
108Version 1.30
109------------
110Allow new nouser_xattr mount parm to disable xattr support for user namespace.
111Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
112(mostly affects NT4 servers) by retry with handle based network operation.
113Add new POSIX Query FS Info for returning statfs info more accurately.
114Handle passwords with multiple commas in them.
115
116Version 1.29
117------------
118Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
119Fix capabilities flags for large readx so as to allow reads larger than 64K.
120
121Version 1.28
122------------
123Add module init parm for large SMB buffer size (to allow it to be changed
124from its default of 16K) which is especially useful for large file copy
125when mounting with the directio mount option. Fix oops after
126returning from mount when experimental ExtendedSecurity enabled and
127SpnegoNegotiated returning invalid error. Fix case to retry better when
128peek returns from 1 to 3 bytes on socket which should have more data.
129Fixed path based calls (such as cifs lookup) to handle path names
130longer than 530 (now can handle PATH_MAX). Fix pass through authentication
131from Samba server to DC (Samba required dummy LM password).
132
133Version 1.27
134------------
135Turn off DNOTIFY (directory change notification support) by default
136(unless built with the experimental flag) to fix hang with KDE
137file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
138waiting on an SMB response) in SendReceive when session dies but
139reconnects quickly from another task. Add module init parms for
140minimum number of large and small network buffers in the buffer pools,
141and for the maximum number of simultaneous requests.
142
143Version 1.26
144------------
145Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
146and other POSIX CIFS compliant servers. Fix error mapping for getfacl
147to EOPNOTSUPP when server does not support posix acls on the wire. Fix
148improperly zeroed buffer in CIFS Unix extensions set times call.
149
150Version 1.25
151------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700152Fix internationalization problem in cifs readdir with filenames that map to
Linus Torvalds1da177e2005-04-16 15:20:36 -0700153longer UTF8 strings than the string on the wire was in Unicode. Add workaround
154for readdir to netapp servers. Fix search rewind (seek into readdir to return
155non-consecutive entries). Do not do readdir when server negotiates
156buffer size to small to fit filename. Add support for reading POSIX ACLs from
157the server (add also acl and noacl mount options).
158
159Version 1.24
160------------
161Optionally allow using server side inode numbers, rather than client generated
162ones by specifying mount option "serverino" - this is required for some apps
163to work which double check hardlinked files and have persistent inode numbers.
164
165Version 1.23
166------------
167Multiple bigendian fixes. On little endian systems (for reconnect after
168network failure) fix tcp session reconnect code so we do not try first
169to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
170as directories rather than symlinks because we can do follow link on them.
171
172Version 1.22
173------------
174Add config option to enable XATTR (extended attribute) support, mapping
175xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
176minor fixes pointed out by the Stanford SWAT checker (mostly missing
177or out of order NULL pointer checks in little used error paths).
178
179Version 1.21
180------------
181Add new mount parm to control whether mode check (generic_permission) is done
182on the client. If Unix extensions are enabled and the uids on the client
183and server do not match, client permission checks are meaningless on
184server uids that do not exist on the client (this does not affect the
185normal ACL check which occurs on the server). Fix default uid
186on mknod to match create and mkdir. Add optional mount parm to allow
187override of the default uid behavior (in which the server sets the uid
188and gid of newly created files). Normally for network filesystem mounts
189user want the server to set the uid/gid on newly created files (rather than
190using uid of the client processes you would in a local filesystem).
191
192Version 1.20
193------------
194Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
195info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
196(in build_wildcard_path_from_dentry). Fix mknod to pass type field
197(block/char/fifo) properly. Remove spurious mount warning log entry when
198credentials passed as mount argument. Set major/minor device number in
199inode for block and char devices when unix extensions enabled.
200
201Version 1.19
202------------
203Fix /proc/fs/cifs/Stats and DebugData display to handle larger
204amounts of return data. Properly limit requests to MAX_REQ (50
205is the usual maximum active multiplex SMB/CIFS requests per server).
206Do not kill cifsd (and thus hurt the other SMB session) when more than one
207session to the same server (but with different userids) exists and one
208of the two user's smb sessions is being removed while leaving the other.
209Do not loop reconnecting in cifsd demultiplex thread when admin
210kills the thread without going through unmount.
211
212Version 1.18
213------------
214Do not rename hardlinked files (since that should be a noop). Flush
215cached write behind data when reopening a file after session abend,
216except when already in write. Grab per socket sem during reconnect
217to avoid oops in sendmsg if overlapping with reconnect. Do not
218reset cached inode file size on readdir for files open for write on
219client.
220
221
222Version 1.17
223------------
224Update number of blocks in file so du command is happier (in Linux a fake
225blocksize of 512 is required for calculating number of blocks in inode).
226Fix prepare write of partial pages to read in data from server if possible.
227Fix race on tcpStatus field between unmount and reconnection code, causing
228cifsd process sometimes to hang around forever. Improve out of memory
229checks in cifs_filldir
230
231Version 1.16
232------------
233Fix incorrect file size in file handle based setattr on big endian hardware.
234Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
235and closing file structs in writepage/partialpagewrite. Add statistics
236for each mounted share (new menuconfig option). Fix endianness problem in
237volume information displayed in /proc/fs/cifs/DebugData (only affects
238affects big endian architectures). Prevent renames while constructing
239path names for open, mkdir and rmdir.
240
241Version 1.15
242------------
243Change to mempools for alloc smb request buffers and multiplex structs
244to better handle low memory problems (and potential deadlocks).
245
246Version 1.14
247------------
248Fix incomplete listings of large directories on Samba servers when Unix
249extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
250rename deadlock when writing out dirty pages at same time.
251
252Version 1.13
253------------
254Fix open of files in which O_CREATE can cause the mode to change in
255some cases. Fix case in which retry of write overlaps file close.
256Fix PPC64 build error. Reduce excessive stack usage in smb password
257hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
258
259Version 1.12
260------------
261Fixes for large file copy, signal handling, socket retry, buffer
262allocation and low memory situations.
263
264Version 1.11
265------------
266Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
267also now allowing support for specifying client netbiosname. NT4 support added.
268
269Version 1.10
270------------
271Fix reconnection (and certain failed mounts) to properly wake up the
272blocked users thread so it does not seem hung (in some cases was blocked
273until the cifs receive timeout expired). Fix spurious error logging
274to kernel log when application with open network files killed.
275
276Version 1.09
277------------
278Fix /proc/fs module unload warning message (that could be logged
279to the kernel log). Fix intermittent failure in connectathon
280test7 (hardlink count not immediately refreshed in case in which
281inode metadata can be incorrectly kept cached when time near zero)
282
283Version 1.08
284------------
285Allow file_mode and dir_mode (specified at mount time) to be enforced
286locally (the server already enforced its own ACLs too) for servers
287that do not report the correct mode (do not support the
288CIFS Unix Extensions).
289
290Version 1.07
291------------
292Fix some small memory leaks in some unmount error paths. Fix major leak
293of cache pages in readpages causing multiple read oriented stress
294testcases (including fsx, and even large file copy) to fail over time.
295
296Version 1.06
297------------
298Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
299This allows files that differ only in case and improves performance of file
300creation and file open to such servers. Fix semaphore conflict which causes
301slow delete of open file to Samba (which unfortunately can cause an oplock
302break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
303
304Version 1.05
305------------
306fixes to cifs_readpages for fsx test case
307
308Version 1.04
309------------
310Fix caching data integrity bug when extending file size especially when no
311oplock on file. Fix spurious logging of valid already parsed mount options
312that are parsed outside of the cifs vfs such as nosuid.
313
314
315Version 1.03
316------------
317Connect to server when port number override not specified, and tcp port
318unitialized. Reset search to restart at correct file when kernel routine
319filldir returns error during large directory searches (readdir).
320
321Version 1.02
322------------
323Fix caching problem when files opened by multiple clients in which
324page cache could contain stale data, and write through did
325not occur often enough while file was still open when read ahead
326(read oplock) not allowed. Treat "sep=" when first mount option
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700327as an override of comma as the default separator between mount
Linus Torvalds1da177e2005-04-16 15:20:36 -0700328options.
329
330Version 1.01
331------------
332Allow passwords longer than 16 bytes. Allow null password string.
333
334Version 1.00
335------------
336Gracefully clean up failed mounts when attempting to mount to servers such as
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700337Windows 98 that terminate tcp sessions during protocol negotiation. Handle
Linus Torvalds1da177e2005-04-16 15:20:36 -0700338embedded commas in mount parsing of passwords.
339
340Version 0.99
341------------
342Invalidate local inode cached pages on oplock break and when last file
343instance is closed so that the client does not continue using stale local
344copy rather than later modified server copy of file. Do not reconnect
345when server drops the tcp session prematurely before negotiate
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700346protocol response. Fix oops in reopen_file when dentry freed. Allow
Linus Torvalds1da177e2005-04-16 15:20:36 -0700347the support for CIFS Unix Extensions to be disabled via proc interface.
348
349Version 0.98
350------------
351Fix hang in commit_write during reconnection of open files under heavy load.
352Fix unload_nls oops in a mount failure path. Serialize writes to same socket
353which also fixes any possible races when cifs signatures are enabled in SMBs
354being sent out of signature sequence number order.
355
356Version 0.97
357------------
358Fix byte range locking bug (endian problem) causing bad offset and
359length.
360
361Version 0.96
362------------
363Fix oops (in send_sig) caused by CIFS unmount code trying to
364wake up the demultiplex thread after it had exited. Do not log
365error on harmless oplock release of closed handle.
366
367Version 0.95
368------------
369Fix unsafe global variable usage and password hash failure on gcc 3.3.1
370Fix problem reconnecting secondary mounts to same server after session
371failure. Fix invalid dentry - race in mkdir when directory gets created
372by another client between the lookup and mkdir.
373
374Version 0.94
375------------
376Fix to list processing in reopen_files. Fix reconnection when server hung
377but tcpip session still alive. Set proper timeout on socket read.
378
379Version 0.93
380------------
381Add missing mount options including iocharset. SMP fixes in write and open.
382Fix errors in reconnecting after TCP session failure. Fix module unloading
383of default nls codepage
384
385Version 0.92

411Retry on ENOSPC and EAGAIN socket errors.
412
413Version 0.87
414------------
415Fix oops on big endian readdir. Set blksize to be even power of two (2**blkbits) to fix

430Finish support for Linux 2.5 open/create changes, which removes the
431redundant NTCreate/QPathInfo/close that was sent during file create.
432Enable oplock by default. Enable packet signing by default (needed to
433access many recent Windows servers)
434
435Version 0.83
436------------
437Fix oops when mounting to long server names caused by inverted parms to kmalloc.
438Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
439we will choose a cifs user session (smb uid) that better matches the local
440uid if a) the mount uid does not match the current uid and b) we have another
441session to the same server (ip address) for a different mount which
442matches the current local uid.
443

453NTLM security case. This should help Windows 2003
454network interoperability since it is common for
455packet signing to be required now. Fix statfs (stat -f)
456which recently started returning errors due to
457invalid value (-1 instead of 0) being set in the
458struct kstatfs f_ffiles field.

473
474Version 0.77
475------------
476Fix display of NTFS DFS junctions to display as symlinks.
477They are the network equivalent. Fix oops in
478cifs_partialpagewrite caused by missing spinlock protection
479of openfile linked list. Allow writebehind caching errors to
480be returned to the application at file close.
481
482Version 0.76
483------------
484Clean up options displayed in /proc/mounts by show_options to
485be more consistent with other filesystems.

490presence or absence of read only dos attribute in mode
491bits for servers that do not support CIFS Unix extensions.
492Fix shortened results on readdir of large directories to
493servers supporting CIFS Unix extensions (caused by
494incorrect resume key).
495
496Version 0.74

508allows disabling caching of attribute information for
509lookups.
510
511Version 0.71
512------------
513Add more oplock handling (distributed caching code). Remove
514dead code. Remove excessive stack space utilization from
515symlink routines.
516
517Version 0.70
518------------
519Fix oops in get dfs referral (triggered when null path sent in to
520mount). Add support for overriding rsize at mount time.
521
522Version 0.69
523------------
524Fix buffer overrun in readdir which caused intermittent kernel oopses.
525Fix writepage code to release kmap on write data. Allow "-ip=" new
526mount option to be passed in on parameter distinct from the first part
527(server name portion of) the UNC name. Allow override of the
528tcp port of the target server via new mount option "-port="
529
530Version 0.68
531------------
532Fix search handle leak on rewind. Fix setuid and gid so that they are
533reflected in the local inode immediately. Cleanup of whitespace
534to make 2.4 and 2.5 versions more consistent.
535
536
537Version 0.67
538------------
539Fix signal sending so that captive thread (cifsd) exits on umount
540(which was causing the warning in kmem_cache_free of the request buffers
541at rmmod time). This had broken as a sideeffect of the recent global
542kernel change to daemonize. Fix memory leak in readdir code which
543showed up in "ls -R" (and applications that did search rewinding).
544
545Version 0.66
546------------
547Reconnect tids and fids after session reconnection (still do not
548reconnect byte range locks though). Fix problem caching
549lookup information for directory inodes, improving performance,
550especially in deep directory trees. Fix various build warnings.
551
552Version 0.65
553------------

556was interrupted by a signal.
557
558Version 0.64
559------------
560Fix data corruption (in partial page after truncate) that caused fsx to
561fail to Windows servers. Cleaned up some extraneous error logging in
562common error paths. Add generic sendfile support.
563
564Version 0.63
565------------
566Fix memory leak in AllocMidQEntry.
567Finish reconnection logic, so connection with server can be dropped
568(or server rebooted) and the cifs client will reconnect.
569
570Version 0.62
571------------
572Fix temporary socket leak when bad userid or password specified
573(or other SMBSessSetup failure). Increase maximum buffer size to slightly
574over 16K to allow negotiation of up to Samba and Windows server default read
575sizes. Add support for readpages
576
577Version 0.61
578------------
579Fix oops when username not passed in on mount. Extensive fixes and improvements
580to error logging (strip redundant newlines, change debug macros to ensure newline
581passed in and to be more consistent). Fix writepage wrong file handle problem,
582a readonly file handle could be incorrectly used to attempt to write out
583file updates through the page cache to multiply open files. This could cause
584the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
585shares to the same Windows server when using different usernames
586(doing this to Samba servers worked but Windows was rejecting it) - now it is
587possible to use different userids when connecting to the same server from a
588Linux client. Fix oops when treeDisconnect called during unmount on
589previously freed socket.
590
591Version 0.60

603Changed read and write to go through pagecache. Added additional address space operations.
604Memory mapped operations now working.
605
606Version 0.57
607------------
608Added writepage code for additional memory mapping support. Fixed leak in xids causing
609the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
610every stat call. Additional formatting cleanup.

684
685Version 0.41
686------------
687Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked

716
717Version 0.34
718------------
719Fixed dentry caching bug, misc. cleanup
720
721Version 0.33
722------------
723Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
724on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.

734------------
7351) Fixed lockrange to be correct (it was one byte too short)
736
7372) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
738show range as locked when there is a conflict with an existing lock.
739
7403) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
741in most cases. Eventually will offer optional ability to query server for the correct perms.
742
7433) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
744but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
745session)
746
7474) Fixed error logging of valid mount options
748
7495) Removed logging of password field.
750
7516) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
752and cleaned them up and made them more consistent with other cifs functions.
753
7547) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700755(with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
Linus Torvalds1da177e2005-04-16 15:20:36 -0700756nor is the symlink support using the Unix extensions
