Allow parsing vers=3.11 on cifs mount

2015-06-28T03:23:32+00:00

Parses and recognizes "vers=3.1.1" on cifs mount and allows sending 0x0311 as a new CIFS/SMB3 dialect. Subsequent patches will add the new negotiate contexts and updated session setup Reviewed-by: Jeff Layton Signed-off-by: Steve French

[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. CC: Steve French CC: Al Viro Signed-off-by: Kees Cook Signed-off-by: Greg Kroah-Hartman

cifs: Add CONFIG_CIFS_DEBUG and rename use of CIFS_DEBUG

This can reduce the size of the module by ~120KB which could be useful for embedded systems. $ size fs/cifs/built-in.o* text data bss dec hex filename 388567 34459 100440 523466 7fcca fs/cifs/built-in.o.new 495970 34599 117904 648473 9e519 fs/cifs/built-in.o.old Signed-off-by: Joe Perches Reviewed-by: Jeff Layton

[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 Reviewed-by: Jeff Layton Signed-off-by: Steve French

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." Reviewed-by: Jeff Layton Reviewed-by: Pavel Shilovsky Signed-off-by: Steve French

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.
