Currently, when we get a prefixpath as part of mount, the kernel only changes the first character to be a '/' or '\' depending on whether posix extensions are enabled. This is problematic as it expects mount.cifs to pass in the correct delimiter in the rest of the prefixpath. But, mount.cifs may not know *what* the correct delimiter is. It's a chicken and egg problem. Note that mount.cifs should not do conversion of the prefixpath - if we want posix behavior then '\' is legal in a path (and we have had bugs in the distant path to prove to me that customers sometimes have apps that require '\'). The kernel code assumes that the path passed in is posix (and current code will handle the first path component fine but was broken for Windows mounts for "deep" prefixpaths unless the user specified a prefixpath with '\' deep in it. So e.g. with current kernel code: 1) mount to //server/share/dir1 will work to all server types 2) mount to //server/share/dir1/subdir1 will work to Samba 3) mount to //server/share/dir1\\subdir1 will work to Windows But case two would fail to Windows without the fix. With the kernel cifs module fix case two now works.

Version 1.52
|
|
------------
|
|
Fix oops on second mount to server when null auth is used.
|
|
Enable experimental Kerberos support. Return writebehind errors on flush
|
|
and sync so that events like out of disk space get reported properly on
|
|
cached files. Fix setxattr failure to certain Samba versions. Fix mount
|
|
of second share to disconnected server session (autoreconnect on this).
|
|
Add ability to modify cifs acls for handling chmod (when mounted with
|
|
cifsacl flag). Fix prefixpath path separator so we can handle mounts
|
|
with prefixpaths longer than one directory (one path component) when
|
|
mounted to Windows servers.
|
|
|
|
Version 1.51
|
|
------------
|
|
Fix memory leak in statfs when mounted to very old servers (e.g.
|
|
Windows 9x). Add new feature "POSIX open" which allows servers
|
|
which support the current POSIX Extensions to provide better semantics
|
|
(e.g. delete for open files opened with posix open). Take into
|
|
account umask on posix mkdir not just older style mkdir. Add
|
|
ability to mount to IPC$ share (which allows CIFS named pipes to be
|
|
opened, read and written as if they were files). When 1st tree
|
|
connect fails (e.g. due to signing negotiation failure) fix
|
|
leak that causes cifsd not to stop and rmmod to fail to cleanup
|
|
cifs_request_buffers pool. Fix problem with POSIX Open/Mkdir on
|
|
bigendian architectures. Fix possible memory corruption when
|
|
EAGAIN returned on kern_recvmsg. Return better error if server
|
|
requires packet signing but client has disabled it. When mounted
|
|
with cifsacl mount option - mode bits are approximated based
|
|
on the contents of the ACL of the file or directory. When cifs
|
|
mount helper is missing convert make sure that UNC name
|
|
has backslash (not forward slash) between ip address of server
|
|
and the share name.
|
|
|
|
Version 1.50
|
|
------------
|
|
Fix NTLMv2 signing. NFS server mounted over cifs works (if cifs mount is
|
|
done with "serverino" mount option). Add support for POSIX Unlink
|
|
(helps with certain sharing violation cases when server such as
|
|
Samba supports newer POSIX CIFS Protocol Extensions). Add "nounix"
|
|
mount option to allow disabling the CIFS Unix Extensions for just
|
|
that mount. Fix hang on spinlock in find_writable_file (race when
|
|
reopening file after session crash). Byte range unlock request to
|
|
windows server could unlock more bytes (on server copy of file)
|
|
than intended if start of unlock request is well before start of
|
|
a previous byte range lock that we issued.
|
|
|
|
Version 1.49
|
|
------------
|
|
IPv6 support. Enable ipv6 addresses to be passed on mount (put the ipv6
|
|
address after the "ip=" mount option, at least until mount.cifs is fixed to
|
|
handle DNS host to ipv6 name translation). Accept override of uid or gid
|
|
on mount even when Unix Extensions are negotiated (it used to be ignored
|
|
when Unix Extensions were ignored). This allows users to override the
|
|
default uid and gid for files when they are certain that the uids or
|
|
gids on the server do not match those of the client. Make "sec=none"
|
|
mount override username (so that null user connection is attempted)
|
|
to match what documentation said. Support for very large reads, over 127K,
|
|
available to some newer servers (such as Samba 3.0.26 and later but
|
|
note that it also requires setting CIFSMaxBufSize at module install
|
|
time to a larger value which may hurt performance in some cases).
|
|
Make sign option force signing (or fail if server does not support it).
|
|
|
|
Version 1.48
|
|
------------
|
|
Fix mtime bouncing around from local idea of last write times to remote time.
|
|
Fix hang (in i_size_read) when simultaneous size update of same remote file
|
|
on smp system corrupts sequence number. Do not reread unnecessarily partial page
|
|
(which we are about to overwrite anyway) when writing out file opened rw.
|
|
When DOS attribute of file on non-Unix server's file changes on the server side
|
|
from read-only back to read-write, reflect this change in default file mode
|
|
(we had been leaving a file's mode read-only until the inode were reloaded).
|
|
Allow setting of attribute back to ATTR_NORMAL (removing readonly dos attribute
|
|
when archive dos attribute not set and we are changing mode back to writeable
|
|
on server which does not support the Unix Extensions). Remove read only dos
|
|
attribute on chmod when adding any write permission (ie on any of
|
|
user/group/other (not all of user/group/other ie 0222) when
|
|
mounted to windows. Add support for POSIX MkDir (slight performance
|
|
enhancement and eliminates the network race between the mkdir and set
|
|
path info of the mode).
|
|
|
|
|
|
Version 1.47
|
|
------------
|
|
Fix oops in list_del during mount caused by unaligned string.
|
|
Fix file corruption which could occur on some large file
|
|
copies caused by writepages page i/o completion bug.
|
|
Seek to SEEK_END forces check for update of file size for non-cached
|
|
files. Allow file size to be updated on remote extend of locally open,
|
|
non-cached file. Fix reconnect to newer Samba servers (or other servers
|
|
which support the CIFS Unix/POSIX extensions) so that we again tell the
|
|
server the Unix/POSIX cifs capabilities which we support (SetFSInfo).
|
|
Add experimental support for new POSIX Open/Mkdir (which returns
|
|
stat information on the open, and allows setting the mode).
|
|
|
|
Version 1.46
|
|
------------
|
|
Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
|
|
Allow null user to be specified on mount ("username="). Do not return
|
|
EINVAL on readdir when filldir fails due to overwritten blocksize
|
|
(fixes FC problem). Return error in rename 2nd attempt retry (ie report
|
|
if rename by handle also fails, after rename by path fails, we were
|
|
not reporting whether the retry worked or not). Fix NTLMv2 to
|
|
work to Windows servers (mount with option "sec=ntlmv2").
|
|
|
|
Version 1.45
|
|
------------
|
|
Do not time out lockw calls when using posix extensions. Do not
|
|
time out requests if server still responding reasonably fast
|
|
on requests on other threads. Improve POSIX locking emulation,
|
|
(lock cancel now works, and unlock of merged range works even
|
|
to Windows servers now). Fix oops on mount to lanman servers
|
|
(win9x, os/2 etc.) when null password. Do not send listxattr
|
|
(SMB to query all EAs) if nouser_xattr specified. Fix SE Linux
|
|
problem (instantiate inodes/dentries in right order for readdir).
|
|
|
|
Version 1.44
|
|
------------
|
|
Rewritten sessionsetup support, including support for legacy SMB
|
|
session setup needed for OS/2 and older servers such as Windows 95 and 98.
|
|
Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
|
|
so we can do search (ls etc.) to OS/2. Do not send NTCreateX
|
|
or recent levels of FindFirst unless server says it supports NT SMBs
|
|
(instead use legacy equivalents from LANMAN dialect). Fix to allow
|
|
NTLMv2 authentication support (now can use stronger password hashing
|
|
on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
|
|
Allow override of global cifs security flags on mount via "sec=" option(s).
|
|
|
|
Version 1.43
|
|
------------
|
|
POSIX locking to servers which support CIFS POSIX Extensions
|
|
(disabled by default controlled by proc/fs/cifs/Experimental).
|
|
Handle conversion of long share names (especially Asian languages)
|
|
to Unicode during mount. Fix memory leak in sess struct on reconnect.
|
|
Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
|
|
cifs open which helps rare case when setpathinfo fails or server does
|
|
not support it.
|
|
|
|
Version 1.42
|
|
------------
|
|
Fix slow oplock break when mounted to different servers at the same time and
|
|
the tids match and we try to find matching fid on wrong server. Fix read
|
|
looping when signing required by server (2.6.16 kernel only). Fix readdir
|
|
vs. rename race which could cause each to hang. Return . and .. even
|
|
if server does not. Allow searches to skip first three entries and
|
|
begin at any location. Fix oops in find_writeable_file.
|
|
|
|
Version 1.41
|
|
------------
|
|
Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
|
|
configure stronger authentication. Fix sfu symlinks so they can
|
|
be followed (not just recognized). Fix wraparound of bcc on
|
|
read responses when buffer size over 64K and also fix wrap of
|
|
max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
|
|
cifs_user_read and cifs_readpages (when EAGAIN on send of smb
|
|
on socket is returned over and over). Add POSIX (advisory) byte range
|
|
locking support (requires server with newest CIFS UNIX Extensions
|
|
to the protocol implemented). Slow down negprot slightly in port 139
|
|
RFC1001 case to give session_init time on buggy servers.
|
|
|
|
Version 1.40
|
|
------------
|
|
Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
|
|
of readpages by eliminating one extra memcpy. Allow update of file size
|
|
from remote server even if file is open for write as long as mount is
|
|
directio. Recognize share mode security and send NTLM encrypted password
|
|
on tree connect if share mode negotiated.
|
|
|
|
Version 1.39
|
|
------------
|
|
Defer close of a file handle slightly if pending writes depend on that handle
|
|
(this reduces the EBADF bad file handle errors that can be logged under heavy
|
|
stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
|
|
Fix SFU style symlinks and mknod needed for servers which do not support the
|
|
CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
|
|
dentries so files that the client sees as deleted but that later get created
|
|
on the server will be recognized. Add client side permission check on setattr.
|
|
Timeout stuck requests better (where server has never responded or sent corrupt
|
|
responses)
|
|
|
|
Version 1.38
|
|
------------
|
|
Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
|
|
to be smaller at first (but increasing) so large write performance performance
|
|
over GigE is better. Do not hang thread on illegal byte range lock response
|
|
from Windows (Windows can send an RFC1001 size which does not match smb size) by
|
|
allowing an SMBs TCP length to be up to a few bytes longer than it should be.
|
|
wsize and rsize can now be larger than negotiated buffer size if server
|
|
supports large readx/writex, even when directio mount flag not specified.
|
|
Write size will in many cases now be 16K instead of 4K which greatly helps
|
|
file copy performance on lightly loaded networks. Fix oops in dnotify
|
|
when experimental config flag enabled. Make cifsFYI more granular.
|
|
|
|
Version 1.37
|
|
------------
|
|
Fix readdir caching when unlink removes file in current search buffer,
|
|
and this is followed by a rewind search to just before the deleted entry.
|
|
Do not attempt to set ctime unless atime and/or mtime change requested
|
|
(most servers throw it away anyway). Fix length check of received smbs
|
|
to be more accurate. Fix big endian problem with mapchars mount option,
|
|
and with a field returned by statfs.
|
|
|
|
Version 1.36
|
|
------------
|
|
Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
|
|
For these older servers, add option for passing netbios name of server in
|
|
on mount (servernetbiosname). Add suspend support for power management, to
|
|
avoid cifsd thread preventing software suspend from working.
|
|
Add mount option for disabling the default behavior of sending byte range lock
|
|
requests to the server (necessary for certain applications which break with
|
|
mandatory lock behavior such as Evolution), and also mount option for
|
|
requesting case insensitive matching for path based requests (requesting
|
|
case sensitive is the default).
|
|
|
|
Version 1.35
|
|
------------
|
|
Add writepage performance improvements. Fix path name conversions
|
|
for long filenames on mounts which were done with "mapchars" mount option
|
|
specified. Ensure multiplex ids do not collide. Fix case in which
|
|
rmmod can oops if done soon after last unmount. Fix truncated
|
|
search (readdir) output when resume filename was a long filename.
|
|
Fix filename conversion when mapchars mount option was specified and
|
|
filename was a long filename.
|
|
|
|
Version 1.34
|
|
------------
|
|
Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
|
|
Do not oops if root user kills cifs oplock kernel thread or
|
|
kills the cifsd thread (NB: killing the cifs kernel threads is not
|
|
recommended, unmount and rmmod cifs will kill them when they are
|
|
no longer needed). Fix readdir to ASCII servers (ie older servers
|
|
which do not support Unicode) and also require asterisk.
|
|
Fix out of memory case in which data could be written one page
|
|
off in the page cache.
|
|
|
|
Version 1.33
|
|
------------
|
|
Fix caching problem, in which readdir of directory containing a file
|
|
which was cached could cause the file's time stamp to be updated
|
|
without invalidating the readahead data (so we could get stale
|
|
file data on the client for that file even as the server copy changed).
|
|
Cleanup response processing so cifsd can not loop when abnormally
|
|
terminated.
|
|
|
|
|
|
Version 1.32
|
|
------------
|
|
Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
|
|
transact response for an SMB request and search entry split across two frames.
|
|
Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
|
|
as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
|
|
unless server explicitly claims to support them in CIFS Unix extensions
|
|
POSIX ACL capability bit. Fix packet signing when multiuser mounting with
|
|
different users from the same client to the same server. Fix oops in
|
|
cifs_close. Add mount option for remapping reserved characters in
|
|
filenames (also allow recognizing files with created by SFU which have any
|
|
of these seven reserved characters, except backslash, to be recognized).
|
|
Fix invalid transact2 message (we were sometimes trying to interpret
|
|
oplock breaks as SMB responses). Add ioctl for checking that the
|
|
current uid matches the uid of the mounter (needed by umount.cifs).
|
|
Reduce the number of large buffer allocations in cifs response processing
|
|
(significantly reduces memory pressure under heavy stress with multiple
|
|
processes accessing the same server at the same time).
|
|
|
|
Version 1.31
|
|
------------
|
|
Fix updates of DOS attributes and time fields so that files on NT4 servers
|
|
do not get marked delete on close. Display sizes of cifs buffer pools in
|
|
cifs stats. Fix oops in unmount when cifsd thread being killed by
|
|
shutdown. Add generic readv/writev and aio support. Report inode numbers
|
|
consistently in readdir and lookup (when serverino mount option is
|
|
specified use the inode number that the server reports - for both lookup
|
|
and readdir, otherwise by default the locally generated inode number is used
|
|
for inodes created in either path since servers are not always able to
|
|
provide unique inode numbers when exporting multiple volumes from under one
|
|
sharename).
|
|
|
|
Version 1.30
|
|
------------
|
|
Allow new nouser_xattr mount parm to disable xattr support for user namespace.
|
|
Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
|
|
(mostly affects NT4 servers) by retry with handle based network operation.
|
|
Add new POSIX Query FS Info for returning statfs info more accurately.
|
|
Handle passwords with multiple commas in them.
|
|
|
|
Version 1.29
|
|
------------
|
|
Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
|
|
Fix capabilities flags for large readx so as to allow reads larger than 64K.
|
|
|
|
Version 1.28
|
|
------------
|
|
Add module init parm for large SMB buffer size (to allow it to be changed
|
|
from its default of 16K) which is especially useful for large file copy
|
|
when mounting with the directio mount option. Fix oops after
|
|
returning from mount when experimental ExtendedSecurity enabled and
|
|
SpnegoNegotiated returning invalid error. Fix case to retry better when
|
|
peek returns from 1 to 3 bytes on socket which should have more data.
|
|
Fixed path based calls (such as cifs lookup) to handle path names
|
|
longer than 530 (now can handle PATH_MAX). Fix pass through authentication
|
|
from Samba server to DC (Samba required dummy LM password).
|
|
|
|
Version 1.27
|
|
------------
|
|
Turn off DNOTIFY (directory change notification support) by default
|
|
(unless built with the experimental flag) to fix hang with KDE
|
|
file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
|
|
waiting on an SMB response) in SendReceive when session dies but
|
|
reconnects quickly from another task. Add module init parms for
|
|
minimum number of large and small network buffers in the buffer pools,
|
|
and for the maximum number of simultaneous requests.
|
|
|
|
Version 1.26
|
|
------------
|
|
Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
|
|
and other POSIX CIFS compliant servers. Fix error mapping for getfacl
|
|
to EOPNOTSUPP when server does not support posix acls on the wire. Fix
|
|
improperly zeroed buffer in CIFS Unix extensions set times call.
|
|
|
|
Version 1.25
|
|
------------
|
|
Fix internationalization problem in cifs readdir with filenames that map to
|
|
longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
|
|
for readdir to netapp servers. Fix search rewind (seek into readdir to return
|
|
non-consecutive entries). Do not do readdir when server negotiates
|
|
buffer size to small to fit filename. Add support for reading POSIX ACLs from
|
|
the server (add also acl and noacl mount options).
|
|
|
|
Version 1.24
|
|
------------
|
|
Optionally allow using server side inode numbers, rather than client generated
|
|
ones by specifying mount option "serverino" - this is required for some apps
|
|
to work which double check hardlinked files and have persistent inode numbers.
|
|
|
|
Version 1.23
|
|
------------
|
|
Multiple bigendian fixes. On little endian systems (for reconnect after
|
|
network failure) fix tcp session reconnect code so we do not try first
|
|
to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
|
|
as directories rather than symlinks because we can do follow link on them.
|
|
|
|
Version 1.22
|
|
------------
|
|
Add config option to enable XATTR (extended attribute) support, mapping
|
|
xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
|
|
minor fixes pointed out by the Stanford SWAT checker (mostly missing
|
|
or out of order NULL pointer checks in little used error paths).
|
|
|
|
Version 1.21
|
|
------------
|
|
Add new mount parm to control whether mode check (generic_permission) is done
|
|
on the client. If Unix extensions are enabled and the uids on the client
|
|
and server do not match, client permission checks are meaningless on
|
|
server uids that do not exist on the client (this does not affect the
|
|
normal ACL check which occurs on the server). Fix default uid
|
|
on mknod to match create and mkdir. Add optional mount parm to allow
|
|
override of the default uid behavior (in which the server sets the uid
|
|
and gid of newly created files). Normally for network filesystem mounts
|
|
user want the server to set the uid/gid on newly created files (rather than
|
|
using uid of the client processes you would in a local filesystem).
|
|
|
|
Version 1.20
|
|
------------
|
|
Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
|
|
info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
|
|
(in build_wildcard_path_from_dentry). Fix mknod to pass type field
|
|
(block/char/fifo) properly. Remove spurious mount warning log entry when
|
|
credentials passed as mount argument. Set major/minor device number in
|
|
inode for block and char devices when unix extensions enabled.
|
|
|
|
Version 1.19
|
|
------------
|
|
Fix /proc/fs/cifs/Stats and DebugData display to handle larger
|
|
amounts of return data. Properly limit requests to MAX_REQ (50
|
|
is the usual maximum active multiplex SMB/CIFS requests per server).
|
|
Do not kill cifsd (and thus hurt the other SMB session) when more than one
|
|
session to the same server (but with different userids) exists and one
|
|
of the two user's smb sessions is being removed while leaving the other.
|
|
Do not loop reconnecting in cifsd demultiplex thread when admin
|
|
kills the thread without going through unmount.
|
|
|
|
Version 1.18
|
|
------------
|
|
Do not rename hardlinked files (since that should be a noop). Flush
|
|
cached write behind data when reopening a file after session abend,
|
|
except when already in write. Grab per socket sem during reconnect
|
|
to avoid oops in sendmsg if overlapping with reconnect. Do not
|
|
reset cached inode file size on readdir for files open for write on
|
|
client.
|
|
|
|
|
|
Version 1.17
|
|
------------
|
|
Update number of blocks in file so du command is happier (in Linux a fake
|
|
blocksize of 512 is required for calculating number of blocks in inode).
|
|
Fix prepare write of partial pages to read in data from server if possible.
|
|
Fix race on tcpStatus field between unmount and reconnection code, causing
|
|
cifsd process sometimes to hang around forever. Improve out of memory
|
|
checks in cifs_filldir
|
|
|
|
Version 1.16
|
|
------------
|
|
Fix incorrect file size in file handle based setattr on big endian hardware.
|
|
Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
|
|
and closing file structs in writepage/partialpagewrite. Add statistics
|
|
for each mounted share (new menuconfig option). Fix endianness problem in
|
|
volume information displayed in /proc/fs/cifs/DebugData (only affects
|
|
affects big endian architectures). Prevent renames while constructing
|
|
path names for open, mkdir and rmdir.
|
|
|
|
Version 1.15
|
|
------------
|
|
Change to mempools for alloc smb request buffers and multiplex structs
|
|
to better handle low memory problems (and potential deadlocks).
|
|
|
|

|
|
allocation and low memory situations.
|
|
|
|
Version 1.11

Version 1.10
|
|

|
|
------------
|
|
Allow file_mode and dir_mode (specified at mount time) to be enforced
|
|
locally (the server already enforced its own ACLs too) for servers

|
|
Version 1.06
|
|
------------
|
|
Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
|
|
This allows files that differ only in case and improves performance of file
|
|
creation and file open to such servers. Fix semaphore conflict which causes
|
|
slow delete of open file to Samba (which unfortunately can cause an oplock
|
|
break to self while vfs_unlink held i_sem) which can hang for 20 seconds.

|
|
filldir returns error during large directory searches (readdir).
|
|
|
|
Version 1.02
|
|
------------
|
|
Fix caching problem when files opened by multiple clients in which
|
|
page cache could contain stale data, and write through did
|
|
not occur often enough while file was still open when read ahead
|
|
(read oplock) not allowed. Treat "sep=" when first mount option
|
|
as an override of comma as the default separator between mount
|
|
options.
|
|
|
|
Version 1.01
|
|
------------
|
|
Allow passwords longer than 16 bytes. Allow null password string.

|
|
Windows 98 that terminate tcp sessions during protocol negotiation. Handle
|
|
embedded commas in mount parsing of passwords.
|
|
|
|
Version 0.99
|
|
------------
|
|
Invalidate local inode cached pages on oplock break and when last file
|
|
instance is closed so that the client does not continue using stale local
|
|
copy rather than later modified server copy of file. Do not reconnect
|
|
when server drops the tcp session prematurely before negotiate
|
|
protocol response. Fix oops in reopen_file when dentry freed. Allow
|
|
the support for CIFS Unix Extensions to be disabled via proc interface.

|
|
being sent out of signature sequence number order.

Fix oops when mounting to long server names caused by inverted parms to kmalloc.
|
|
Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled

------------
|
|
Finish up CIFS packet digital signing for the default
|
|
NTLM security case. This should help Windows 2003
|
|
network interoperability since it is common for
|
|
packet signing to be required now. Fix statfs (stat -f)
|

presence or absence of read only dos attribute in mode
|
|
bits for servers that do not support CIFS Unix extensions.
|
|
Fix shortened results on readdir of large directories to
|

|
Version 0.74
|
|

|
Version 0.67
|
|
------------
|
|
Fix signal sending so that captive thread (cifsd) exits on umount

|
at rmmod time). This had broken as a sideeffect of the recent global
|
|
kernel change to daemonize. Fix memory leak in readdir code which
|

|
|
|
|
Version 0.66
|
|
------------
|
|
Reconnect tids and fids after session reconnection (still do not
|
|
reconnect byte range locks though). Fix problem caching
|
|
lookup information for directory inodes, improving performance,
|
|
especially in deep directory trees. Fix various build warnings.
|

sizes. Add support for readpages
|
|
|
|
Version 0.61
|
|
------------
|
|
Fix oops when username not passed in on mount. Extensive fixes and improvements
|
|
to error logging (strip redundant newlines, change debug macros to ensure newline
|
|
passed in and to be more consistent). Fix writepage wrong file handle problem,
|
|
a readonly file handle could be incorrectly used to attempt to write out
|
|
file updates through the page cache to multiply open files. This could cause
|
|
the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
|
|
shares to the same Windows server when using different usernames
|
|
(doing this to Samba servers worked but Windows was rejecting it) - now it is
|
|
possible to use different userids when connecting to the same server from a
|

|
|
previously freed socket.

session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
|
|
Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs

Version 0.31
|
|
------------
|
|
1) Fixed lockrange to be correct (it was one byte too short)
|
|
|
|
2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
|
|
show range as locked when there is a conflict with an existing lock.
|
|
|
|
3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
|
|
in most cases. Eventually will offer optional ability to query server for the correct perms.
|
|
|
|
3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
|
|
but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
|
|
session)
|
|
|
|
4) Fixed error logging of valid mount options
|
|
|
|
5) Removed logging of password field.
|
|
|
|
6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
|
|
and cleaned them up and made them more consistent with other cifs functions.
|
|
|
|
7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
|
|
(with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
|
|
nor is the symlink support using the Unix extensions
|
|
|
|
8) Started adding the readlink and follow_link code
