Replace the "marshal_iov" function with a "read_into_pages" function. That function will copy the read data off the socket and into the pages array, kmapping and reading pages one at a time. Signed-off-by:Jeff Layton <jlayton@redhat.com>

We'll need an array to put into a smb_rqst, so convert this into an array instead of (ab)using the lru list_head. Signed-off-by: -

Eventually, we're going to want to append a list of pages to cifs_readdata instead of a list of kvecs. To prepare for that, turn the kvec array allocation into a separate one and just keep a pointer to it in the readdata. Signed-off-by: -

Now that we're using TCP_CORK on the socket, there's no value in continuting to support this option. Schedule it for removal in 3.9. Reviewed-by:

Now that we're not kmapping so much at once, there's no need to cap the wsize at the amount that can be simultaneously kmapped. Reviewed-by:

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. Reviewed-by:

Use the smb_send_rqst helper function to kmap each page in the array and update the hash for that chunk. Reviewed-by:

Add code that allows smb_send_rqst to send an array of pages after the initial kvec array has been sent. For now, we simply kmap the page array and send it using the standard smb_send_kvec function. Eventually, we may want to convert this code to use kernel_sendpage under the hood and avoid the kmap altogether for the page data. Reviewed-by:

We want to send SMBs as "atomically" as possible. Prior to sending any data on the socket, cork it to make sure that no non-full frames go out. Afterward, uncork it to make sure all of the data gets pushed out to the wire. Note that this more or less renders the socket=TCP_NODELAY mount option obsolete. When TCP_CORK and TCP_NODELAY are used on the same socket, TCP_NODELAY is essentially ignored. Acked-by:

Again, just a change in the arguments and some function renaming here. In later patches, we'll change this code to deal with page arrays. In this patch, we add a new smb_send_rqst wrapper and have smb_sendv call that. Then we move most of the existing smb_sendv code into a new function -- smb_send_kvec. This seems a little redundant, but later we'll flesh this out to deal with arrays of pages. Reviewed-by:

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. Reviewed-by:

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. Signed-off-by:
