* SMB2 FSCTL and IOCTL worker functionSteve French2013-06-274-0/+147
| | | | | | | | | | | | | | | | | | | | | | | This worker function is needed to send SMB2 fsctl (and ioctl) requests including: validating negotiation info (secure negotiate) querying the servers network interfaces copy offload (refcopy) Followon patches for the above three will use this. This patch also does general validation of the response. In the future, as David Disseldorp notes, for the copychunk ioctl case, we will want to enhance the response processing to allow returning the chunk request limits to the caller (even though the server returns an error, in that case we would return data that the caller could use - see 2.2.32.1). See MS-SMB2 Section 2.2.31 for more details on format of fsctl. Acked-by: Pavel Shilovsky <piastry@etersoft.ru> Signed-off-by: Steve French <smfrench@gmail.com>
* Charge at least one credit, if server says that it supports multicreditSteve French2013-06-271-1/+8
| | | | | | | | | | | | In SMB2.1 and later the server will usually set the large MTU flag, and we need to charge at least one credit, if server says that since it supports multicredit. Windows seems to let us get away with putting a zero there, but they confirmed that it is wrong and the spec says to put one there (if the request is under 64K and the CAP_LARGE_MTU was returned during protocol negotiation by the server.

* cifs: update the default global_secflags to include "raw" NTLMv2Jeff Layton2013-06-241-1/+1
| | | | | | | | | | | | | | | Before this patchset, the global_secflags could only offer up a single sectype. With the new set though we have the ability to allow different sectypes since we sort out the one to use after talking to the server. Change the global_secflags to allow NTLMSSP or NTLMv2 by default. If the server sets the extended security bit in the Negotiate response, then we'll use NTLMSSP. If it doesn't then we'll use raw NTLMv2. Mounting a LANMAN server will still require a sec= option by default.

* move sectype to the cifs_ses instead of TCP_Server_InfoJeff Layton2013-06-247-180/+115
| | | | | | | | | | | | | | | | Now that we track what sort of NEGOTIATE response was received, stop mandating that every session on a socket use the same type of auth. Push that decision out into the session setup code, and make the sectype a per-session property. This should allow us to mix multiple sectypes on a socket as long as they are compatible with the NEGOTIATE response. With this too, we can now eliminate the ses->secFlg field since that info is redundant and harder to work with than a securityEnum.

* cifs: track the enablement of signing in the TCP_Server_InfoJeff Layton2013-06-2410-82/+71
| | | | | | | | | | | | | | | | | | | | | Currently, we determine this according to flags in the sec_mode, flags in the global_secflags and via other methods. That makes the semantics very hard to follow and there are corner cases where we don't handle this correctly. Add a new bool to the TCP_Server_Info that acts as a simple flag to tell us whether signing is enabled on this connection or not, and fix up the places that need to determine this to use that flag. This is a bit weird for the SMB2 case, where signing is per-session. SMB2 needs work in this area already though. The existing SMB2 code has similar logic to what we're using here, so there should be no real change in behavior. These changes should make it easier to implement per-session signing in the future though.

Only indicate an I/O error if the condition on open() actually exists.

Previously if trying to deallocate VT1 and it is busy, we would return EBUSY. The commit changed this to return 0 (success). This commit restores the old behavior.

Both are CC'ed to stable. The remaining two are specific to recent iscsi-target + iser conversion changes. One drops some left-over debug noise, and Andy's patch fixes configfs attribute handling during an explicit network portal feature bit disable when iser-target is unsupported." * git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: iscsi-target: Remove left over v3.10-rc debug printks target/iscsi: Fix op=disable + error handling cases in np_store_iser tcm_qla2xxx: Fix residual for underrun commands that fail target/iscsi: don't corrupt bh_count in iscsit_stop_time2retain_timer()
