2018-10-24cifs: change SMB2_OP_RENAME and SMB2_OP_HARDLINK to use compoundingRonnie Sahlberg1-1/+1
Get rid of smb2_open_op_close() as all operations are now migrated to smb2_compound_op(). Signed-off-by: Ronnie Sahlberg <lsahlber@redhat.com> Signed-off-by: Steve French <stfrench@microsoft.com>
2018-06-01cifs: remove struct smb2_hdrRonnie Sahlberg1-5/+0
struct smb2_hdr is now just a wrapper for smb2_sync_hdr. We can thus get rid of smb2_hdr completely and access the sync header directly. Signed-off-by: Ronnie Sahlberg <lsahlber@redhat.com> Signed-off-by: Steve French <stfrench@microsoft.com>
2017-02-02CIFS: Separate SMB2 header structurePavel Shilovsky1-0/+5
In order to support compounding and encryption we need to separate RFC1001 length field and SMB2 header structure because the protocol treats them differently. This change will allow to simplify parsing of such complex SMB2 packets further. Signed-off-by: Pavel Shilovsky <pshilov@microsoft.com>
2016-05-17remove directory incorrectly tries to set delete on close on non-empty ↵Steve French1-0/+1
directories Wrong return code was being returned on SMB3 rmdir of non-empty directory. For SMB3 (unlike for cifs), we attempt to delete a directory by set of delete on close flag on the open. Windows clients set this flag via a set info (SET_FILE_DISPOSITION to set this flag) which properly checks if the directory is empty. With this patch on smb3 mounts we correctly return "DIRECTORY NOT EMPTY" on attempts to remove a non-empty directory.

2014-02-15CIFS: Fix too big maxBuf size for SMB3 mountsPavel Shilovsky1-0/+3
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.

2013-06-27[CIFS] SMB3 Signing enablementSteve French1-0/+2
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.

2012-09-25CIFS: Enable signing in SMB2Pavel Shilovsky1-0/+4
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.
