When we have a file opened with read oplock and we are writing a data to this file, we need to store the data in the cache and then send to the server to ensure that the next read operation will get a coherent data. Also mark it as CONFIG_CIFS_SMB2 because it's more suitable for SMB2 code but can fix some CIFS problems too (when server delays sending an oplock break after a write request). We can drop this ifdefs dependence in future. Signed-off-by: NPavel Shilovsky <piastry@etersoft.ru> Signed-off-by: NSteve French <sfrench@us.ibm.com>

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>

Now we need to lock/unlock a spinlock while processing brlock ops on the inode. Move brlocks of a fid to a separate list and attach all such lists to the inode. This let us not hold a spinlock. Signed-off-by: NPavel Shilovsky <pshilovsky@samba.org>

Now that we aren't abusing the kmap address space, there's no need for this lock or to impose a limit on the rsize. Signed-off-by: NJeff Layton <jlayton@redhat.com>

The array is no longer needed. We just need a single kvec to hold the header for signature checking. Signed-off-by: NJeff Layton <jlayton@redhat.com>

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: NJeff 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: NJeff Layton <jlayton@redhat.com>

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: NJeff Layton <jlayton@redhat.com>

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: NPavel Shilovsky <pshilovsky@samba.org> Signed-off-by: NJeff Layton <jlayton@redhat.com>

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: NPavel Shilovsky <pshilovsky@samba.org> Signed-off-by: NJeff Layton <jlayton@redhat.com> Signed-off-by: NSteve French <smfrench@gmail.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>

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.

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.

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.

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.
