cifs-bld-tmp/fs/cifs/CHANGES → new-cifs-backport/CHANGES
View file @ 9054cc31
Verison 1.48
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).

rsize default read size (usually 16K). The client currently
can not use rsize larger than CIFSMaxBufSize. CIFSMaxBufSize
defaults to 16K and may be changed (from 8K to the maximum
kmalloc size allowed by your kernel) at module install time
for cifs.ko. Setting CIFSMaxBufSize to a very large value
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
set from a minimum of 2048 to a maximum of 130048 (127K or
CIFSMaxBufSize, whichever is smaller)

* server inode numbers instead of locally generated temporary ones).
