The readpages bug is a regression that was introduced in 6993f74a. This also fixes a couple of similar bugs in the uncached read and write codepaths. Also, prevent this sort of thing in the future by having cifsFileInfo_get take the spinlock itself, and adding a _locked variant for use in places that are already holding the lock. The _put code has always done that so this makes for a less confusing interface. Cc: <stable@vger.kernel.org> # 3.5.x Reviewed-by:

Since both CIFS and SMB2 use ses->capabilities (server->capabilities) field but flags are different we should make such checks protocol independent. Reviewed-by:

Since there are only 19 command codes, it also is easier to track by exact command code than it was for cifs. Signed-off-by:

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:

Add mapping table for 32 bit SMB2 status codes to linux errors. Note that SMB2 does not use DOS/OS2 errors (ever) so mapping to DOS/OS2 errors as a common network subset (as we do for cifs) doesn't help. And note that the set of status codes is much more complete here. Signed-off-by:

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. Acked-by:

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. Reported-by:

Calling key_revoke here isn't ideal as further requests for the key will end up returning -EKEYREVOKED until it gets purged from the cache. What we really intend here is to force a new upcall on the next request_key. Cc: David Howells <dhowells@redhat.com> Signed-off-by:
