From be1350004392961f4390f48c8001350712ed55f1 Mon Sep 17 00:00:00 2001 From: Steve French Date: Sat, 26 Mar 2022 16:17:03 -0500 Subject: smb3: move defines for query info and query fsinfo to smbfs_common 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 Signed-off-by: Steve French --- fs/smbfs_common/smb2pdu.h | 316 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 316 insertions(+) (limited to 'fs/smbfs_common') diff --git a/fs/smbfs_common/smb2pdu.h b/fs/smbfs_common/smb2pdu.h index 67b41f083025..1defcc8d6c2c 100644 --- a/fs/smbfs_common/smb2pdu.h +++ b/fs/smbfs_common/smb2pdu.h @@ -787,6 +787,123 @@ struct smb2_flush_rsp { __le16 Reserved; } __packed; +#define SMB2_LOCKFLAG_SHARED 0x0001 +#define SMB2_LOCKFLAG_EXCLUSIVE 0x0002 +#define SMB2_LOCKFLAG_UNLOCK 0x0004 +#define SMB2_LOCKFLAG_FAIL_IMMEDIATELY 0x0010 +#define SMB2_LOCKFLAG_MASK 0x0007 + +struct smb2_lock_element { + __le64 Offset; + __le64 Length; + __le32 Flags; + __le32 Reserved; +} __packed; + +struct smb2_lock_req { + struct smb2_hdr hdr; + __le16 StructureSize; /* Must be 48 */ + __le16 LockCount; + /* + * The least significant four bits are the index, the other 28 bits are + * the lock sequence number (0 to 64).
