* cifs: abstract out function to marshal the iovec for readv receivesJeff Layton2012-05-171-0/+2
| | | | | | | | Cached and uncached reads will need to do different things here to handle the difference when the pages are in pagecache and not. Abstract out the function that marshals the page list into a kvec array. Signed-off-by: Jeff Layton <jlayton@redhat.com>

* cifs: Assume passwords are encoded according to iocharset (try #2)Shirish Pargaonkar2011-10-301-3/+5
| | | | | | | | | | | | | | | | | | | | | | Re-posting a patch originally posted by Oskar Liljeblad after rebasing on 3.2. Modify cifs to assume that the supplied password is encoded according to iocharset. Before this patch passwords would be treated as raw 8-bit data, which made authentication with Unicode passwords impossible (at least passwords with characters > 0xFF). The previous code would as a side effect accept passwords encoded with ISO 8859-1, since Unicode < 0x100 basically is ISO 8859-1. Software which relies on that will no longer support password chars > 0x7F unless it also uses iocharset=iso8859-1. (mount.cifs does not care about the encoding so it will work as expected.)

* cifs: add cifs_async_readvJeff Layton2011-10-191-0/+24
| | | | | | | | | | | | | | | | | | ...which will allow cifs to do an asynchronous read call to the server. The caller will allocate and set up cifs_readdata for each READ_AND_X call that should be issued on the wire. The pages passed in are added to the pagecache, but not placed on the LRU list yet (as we need the page->lru to keep the pages on the list in the readdata). When cifsd identifies the mid, it will see that there is a special receive handler for the call, and use that to receive the rest of the frame. cifs_readv_receive will then marshal up a kvec array with kmapped pages from the pagecache, which eliminates one copy of the data. Once the data is received, the pages are added to the LRU list, set uptodate, and unlocked.

* cifs: add a callback function to receive the rest of the frameJeff Layton2011-10-191-2/+3
| | | | | | | | | | | | | | | In order to handle larger SMBs for readpages and other calls, we want to be able to read into a preallocated set of buffers. Rather than changing all of the existing code to preallocate buffers however, we instead add a receive callback function to the MID. cifsd will call this function once the mid_q_entry has been identified in order to receive the rest of the SMB. If the mid can't be identified or the receive pointer is unset, then the standard 3rd phase receive function will be called.

Initially security descriptor was built to change only (D)ACL, that functionality has been extended. When either an Owner or a Group of a file object at the server is changed, rest of security descriptor remains same (DACL etc.). To set security descriptor, it is necessary to open that file with permission bits of either WRITE_DAC if DACL is being modified or WRITE_OWNER (Take Ownership) if Owner or Group is being changed. It is the server that decides whether a set security descriptor with either owner or group change succeeds or not.

| | | | | | | | | | | | | | | | | | Add rwpidforward mount option that switches on a mode when we forward pid of a process who opened a file to any read and write operation. This can prevent applications like WINE from failing on read or write operation on a previously locked file region from the same netfd from another process if we use mandatory brlock style. It is actual for WINE because during a run of WINE program two processes work on the same netfd - share the same file struct between several VFS fds: 1) WINE-server does open and lock; 2) WINE-application does read and write.

* cifs: keep BCC in little-endian formatJeff Layton2011-05-191-1/+0Star
| | | | | | | | | | | | | | | | | | | | | | | This is the same patch as originally posted, just with some merge conflicts fixed up... Currently, the ByteCount is usually converted to host-endian on receive. This is confusing however, as we need to keep two sets of routines for accessing it, and keep track of when to use each routine. Munging received packets like this also limits when the signature can be calulated. Simplify the code by keeping the received ByteCount in little-endian format. This allows us to eliminate a set of routines for accessing it and we can now drop the *_le suffixes from the accessor functions since that's now implied. While we're at it, switch all of the places that read the ByteCount directly to use the get_bcc inline which should also clean up some unaligned accesses.
