2022-05-23Add various fsctl structsSteve French1-7/+101
Add missing structure definition for various newer fsctl operations - duplicate_extents_ex - get_integrity_information - query_file_regions - query_on_disk_volume_info And move some fsctl defintions to smbfs_common Signed-off-by: Steve French <stfrench@microsoft.com>
2022-05-23Add defines for various newer FSCTLsSteve French1-0/+6
Checking MS-FSCC section 2.3 found six FSCTL defines that were missing Reviewed-by: David Disseldorp <ddiss@suse.de> Signed-off-by: Steve French <stfrench@microsoft.com>
2022-03-31smb3: fix ksmbd bigendian bug in oplock break, and move its struct to smbfs_commonSteve French1-0/+113
Fix an endian bug in ksmbd for one remaining use of Persistent/VolatileFid that unnecessarily converted it (it is an opaque endian field that does not need to be and should not be converted) in oplock_break for ksmbd, and move the definitions for the oplock and lease break protocol requests and responses to fs/smbfs_common/smb2pdu.h Also move a few more definitions for various protocol requests that were duplicated (in fs/cifs/smb2pdu.h and fs/ksmbd/smb2pdu.h) into fs/smbfs_common/smb2pdu.h including: - various ioctls and reparse structures - validate negotiate request and response structs - duplicate extents structs Reviewed-by: Paulo Alcantara (SUSE) <pc@cjr.nz> Reviewed-by: Namjae Jeon <linkinjeon@kernel.org> Signed-off-by: Steve French <stfrench@microsoft.com>
2022-03-26smb3: move defines for query info and query fsinfo to smbfs_commonSteve French1-0/+316
Includes moving to common code (from cifs and ksmbd protocol related headers) - query and query directory info levels and structs - set info structs - SMB2 lock struct and flags - SMB2 echo req Also shorten a few flag names (e.g. SMB2_LOCKFLAG_EXCLUSIVE_LOCK to SMB2_LOCKFLAG_EXCLUSIVE) Reviewed-by: Namjae Jeon <linkinjeon@kernel.org> Signed-off-by: Steve French <stfrench@microsoft.com>
2022-03-26smb3: move defines for ioctl protocol header and SMB2 sizes to smbfs_commonSteve French1-0/+85
The definitions for the ioctl SMB3 request and response as well as length of various fields defined in the protocol documentation were duplicated in fs/ksmbd and fs/cifs. Move these to the common code in fs/smbfs_common/smb2pdu.h Reviewed-by: Namjae Jeon <linkinjeon@kernel.org> Signed-off-by: Steve French <stfrench@microsoft.com>
2022-03-25[smb3] move more common protocol header definitions to smbfs_commonSteve French1-0/+101
We have duplicated definitions for various SMB3 PDUs in fs/ksmbd and fs/cifs. Some had already been moved to fs/smbfs_common/smb2pdu.h Move definitions for - error response - query info and various related protocol flags - various lease handling flags and the create lease context to smbfs_common/smb2pdu.h to reduce code duplication Reviewed-by: Namjae Jeon <linkinjeon@kernel.org> Signed-off-by: Steve French <stfrench@microsoft.com>
2022-03-23cifs: fix bad fids sent over wirePaulo Alcantara1-12/+12
The client used to partially convert the fids to le64, while storing or sending them by using host endianness. This broke the client on big-endian machines. Instead of converting them to le64, store them as opaque integers and then avoid byteswapping when sending them over wire.

2022-01-18smb3: add new defines from protocol specificationSteve French2-1/+3
In the October updates to MS-SMB2 two additional FSCTLs were described. Add the missing defines for these, as well as fix a typo in an earlier define. Reviewed-by: Ronnie Sahlberg <lsahlber@redhat.com> Signed-off-by: Steve French <stfrench@microsoft.com>
2021-12-07cifs: Fix crash on unload of cifs_arc4.koVincent Whitchurch1-13/+0
The exit function is wrongly placed in the __init section and this leads to a crash when the module is unloaded. Just remove both the init and exit functions since this module does not need them.

2021-11-05cifs: Create a new shared file holding smb2 pdu definitionsRonnie Sahlberg1-0/+318
This file will contain all the definitions we need for SMB2 packets and will follow the naming convention of MS-SMB2.PDF as closely as possible to make it easier to cross-reference beween the definitions and the standard. The content of this file will mostly consist of migration of existing definitions in the cifs/smb2.pdu.h and ksmbd/smb2pdu.h files with some additional tweaks as the two files have diverged. This patch introduces the new smbfs_common/smb2pdu.h file and migrates the SMB2 header as well as TREE_CONNECT and TREE_DISCONNECT to the shared file.

2021-09-13cifs: remove pathname for file from SPDX headerSteve French1-1/+1
checkpatch complains about source files with filenames (e.g. in these cases just below the SPDX header in comments at the top of various files in fs/cifs). It also is helpful to change this now so will be less confusing when the parent directory is renamed e.g. from fs/cifs to fs/smb_client (or fs/smbfs) Reviewed-by: Ronnie Sahlberg <lsahlber@redhat.com> Signed-off-by: Steve French <stfrench@microsoft.com>
2021-09-09cifs: move SMB FSCTL definitions to common codeSteve French1-0/+162
The FSCTL definitions are in smbfsctl.h which should be shared by client and server. Move the updated version of smbfsctl.h into smbfs_common and have the client code use it (subsequent patch will change the server to use this common version of the header).

2021-09-08cifs: rename cifs_common to smbfs_commonSteve French5-0/+341
As we move to common code between client and server, we have been asked to make the names less confusing, and refer less to "cifs" and more to words which include "smb" instead to e.g. "smbfs" for the client (we already have "ksmbd" for the kernel server, and "smbd" for the user space Samba daemon). So to be more consistent in the naming of common code between client and server and reduce the risk of merge conflicts as more common code is added - rename "cifs_common" to "smbfs_common" (in future releases we also will rename the fs/cifs directory to fs/smbfs) Reviewed-by: Ronnie Sahlberg <lsahlber@redhat.com> Signed-off-by: Steve French <stfrench@microsoft.com>
