[CIFS] SMB3 Signing enablement

2013-06-27T04:45:05+00:00

SMB3 uses a much faster method of signing (which is also better in other ways),
AES-CMAC.  With the kernel now supporting AES-CMAC since last release, we
are overdue to allow SMB3 signing (today only CIFS and SMB2 and SMB2.1,
but not SMB3 and SMB3.1 can sign) - and we need this also for checking
secure negotation and also per-share encryption (two other new SMB3 features
which we need to implement).

This patch needs some work in a few areas - for example we need to
move signing for SMB2/SMB3 from per-socket to per-user (we may be able to
use the "nosharesock" mount option in the interim for the multiuser case),
and Shirish found a bug in the earlier authentication overhaul
(setting signing flags properly) - but those can be done in followon
patches.

fs/cifs: remove depends on CONFIG_EXPERIMENTAL

2013-01-21T22:39:05+00:00

The CONFIG_EXPERIMENTAL config item has not carried much meaning for a
while now and is almost always enabled by default. As agreed during the
Linux kernel summit, remove it from any "depends on" lines in Kconfigs.

cifs: Add CONFIG_CIFS_DEBUG and rename use of CIFS_DEBUG

2012-12-05T20:58:36+00:00

This can reduce the size of the module by ~120KB which
could be useful for embedded systems.

[CIFS] Fix indentation of fs/cifs/Kconfig entries

2012-10-01T17:48:03+00:00

make menuconfig for cifs shows multiple entries toward
the end of the list with the incorrect indentation
(probably a bug in Kconfig parsing of items
that are dependant on the module (cifs=m instead of
just CONFIG_CIFS).  This patch fixes the indentation
of all but the last entry (CIFS_ACL) which I don't
know how to fix. It also clarifies wording in
two places

MARK SMB2 support EXPERIMENTAL

2012-09-25T02:46:34+00:00

Now that the merge of the remaining pieces needed for
SMB2 (SMB2.1 dialect) are in, and most test cases pass,
we can consider SMB2.1 EXPERIMENTAL rather than "BROKEN."

CIFS: Enable signing in SMB2

2012-09-25T02:46:28+00:00

Use hmac-sha256 and rather than hmac-md5 that is used for CIFS/SMB.

Signature field in SMB2 header is 16 bytes instead of 8 bytes.

Automatically enable signing by client when requested by the server
when signing ability is available to the client.

CIFS: Introduce SMB2 Kconfig option

2012-05-23T08:33:14+00:00

SMB2 is the followon to the CIFS (and SMB) protocols
and the default for Windows since Windows Vista, and also
now implemented by various non-Windows servers. SMB2
is more secure, has various performance advantages, including
larger i/o sizes, flow control, better caching model and more.
SMB2 also resolves some scalability limits in the CIFS
protocol and adds many new features while being much
simpler (only a few dozen commands instead of hundreds)
and since the protocol is clearer it is also more consistently
implemented across servers and thus easier to optimize.

After much discussion with Jeff Layton, Jeremy Allison
and others at Connectathon, we decided to move the SMB2
code from a distinct .ko and fstype into distinct
C files that optionally build in cifs.ko. As a result
the Kconfig gets simpler.

To avoid destabilizing CIFS, the SMB2 code is going
to be moved into its own experimental CONFIG_CIFS_SMB2 ifdef
as it is merged and rereviewed. The changes to stable
CIFS (builds with the SMB2 ifdef off) are expected to be
fairly small.
