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).
Version 1.49
------------
IPv6 support. Enable ipv6 addresses to be passed on mount (put the ipv6

gids on the server do not match those of the client. Make "sec=none"

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).

rsize default read size (usually 16K). The client currently

defaults to 16K and may be changed (from 8K to the maximum
kmalloc size allowed by your kernel) at module install time

will cause cifs to use more memory and may reduce performance
in some cases. To use rsize greater than 127K (the original
cifs protocol maximum) also requires that the server support
a new Unix Capability flag (for very large read) which some
newer servers (e.g. Samba 3.0.26 or later) do. rsize can be

* See Documentation/filesystems/Exporting

*
* Since cifs is a network file system, an "fsid" must be included for
* any nfs exports file entries which refer to cifs paths. In addition
* the cifs mount must be mounted with the "serverino" option (ie use stable
* server inode numbers instead of locally generated temporary ones).
* Although cifs inodes do not use generation numbers (have generation number
* of zero) - the inode number alone should be good enough for simple cases
* in which users want to export cifs shares with NFS. The decode and encode
* could be improved by using a new routine which expects 64 bit inode numbers
* instead of the default 32 bit routines in fs/exportfs
