SMB3 servers can respond with MaxTransactSize of more than 4M
that can cause a memory allocation error returned from kmalloc
in a lock codepath. Also the client doesn't support multicredit
requests now and allows buffer sizes of 65536 bytes only. Set
MaxTransactSize to this maximum supported value.

[CIFS] SMB3 Signing enablement2013-06-27T04:45:05+00:00Steve Frenchsmfrench@gmail.com2013-06-27T04:45:05+00:00urn:sha1:429b46f4fdaf9c9007b7c0fc371b94e40c3764b2
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.

CIFS: Enable signing in SMB22012-09-25T02:46:28+00:00Pavel Shilovskypshilovsky@samba.org2012-09-18T23:20:30+00:00urn:sha1:3c1bf7e48e9e463b65b1b90da4500a93dd2b27a7
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.
