Currently CIFS code accept read/write ops on mandatory locked area when two processes use the same file descriptor - it's wrong. Fix this by serializing io and brlock operations on the inode. Signed-off-by: NPavel Shilovsky <pshilovsky@etersoft.ru> Signed-off-by: NSteve French <sfrench@us.ibm.com>

For now, none of the callers populate rq_pages. That will be done for writes in a later patch. While we're at it, change the prototype of setup_async_request not to need a return pointer argument. Just return the pointer to the mid_q_entry or an ERR_PTR.

Use the smb_send_rqst helper function to kmap each page in the array and update the hash for that chunk. Reviewed-by: NPavel Shilovsky <pshilovsky@samba.org> Signed-off-by: NJeff Layton <jlayton@redhat.com> Signed-off-by: NSteve French <smfrench@gmail.com>

We need a way to represent a call to be sent on the wire that does not require having all of the page data kmapped. Behold the smb_rqst struct. This new struct represents an array of kvecs immediately followed by an array of pages. Convert the signing routines to use these structs under the hood and turn the existing functions for this into wrappers around that. For now, we're just changing these functions to take different args. Later, we'll teach them how to deal with arrays of pages.

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.

For SMB2 protocol we can add more than one credit for one received request: it depends on CreditRequest field in SMB2 response header. Also we divide all requests by type: echoes, oplocks and others. Each type uses its own slot pull. Reviewed-by: NJeff Layton <jlayton@redhat.com> Signed-off-by: NPavel Shilovsky <pshilovsky@samba.org> Signed-off-by: NSteve French <smfrench@gmail.com>

Split all requests to echos, oplocks and others - each group uses its own credit slot. This is indicated by new flags CIFS_ECHO_OP and CIFS_OBREAK_OP that are not used now for CIFS. This change is required to support SMB2 protocol because of different processing of these commands.

struct file_lock is pretty large, so we really don't want that on the stack in a potentially long call chain. Reorganize the arguments to CIFSSMBPosixLock to eliminate the need for that. Eliminate the get_flag and simply use a non-NULL pLockInfo to indicate that this is a "get" operation. In order to do that, need to add a new loff_t argument for the start_offset.

As observed and suggested by Tushar Gosavi... --------- readdir calls these function to send TRANS2_FIND_FIRST and TRANS2_FIND_NEXT command to the server. The current cifs module is not specifying CIFS_SEARCH_BACKUP_SEARCH flag while sending these command when backupuid/backupgid is specified. This can be resolved by specifying CIFS_SEARCH_BACKUP_SEARCH flag. --------- Cc: <stable@kernel.org> Reported-and-Tested-by: NTushar Gosavi <tugosavi@in.ibm.com> Signed-off-by: NShirish Pargaonkar <shirishpargaonkar@gmail.com> Acked-by: NJeff Layton <jlayton@redhat.com> Signed-off-by: NSteve French <sfrench@us.ibm.com>

Convert cifs_iovec_read to use async I/O. This also raises the limit on the rsize for uncached reads. We first allocate a set of pages to hold the replies, then issue the reads in parallel and then collect the replies and copy the results into the iovec. A possible future optimization would be to kmap and inline the iovec buffers and read the data directly from the socket into that. That would require some rather complex conversion of the iovec into a kvec however. Signed-off-by: NJeff Layton <jlayton@redhat.com>
