2011-01-20cifs: clean up unaligned accesses in validate_t2Jeff Layton

2011-01-20cifs: use get/put_unaligned functions to access ByteCountJeff Layton
It's possible that when we access the ByteCount that the alignment will be off. Most CPUs deal with that transparently, but there's usually some performance impact. Some CPUs raise an exception on unaligned accesses. Fix this by accessing the byte count using the get_unaligned and put_unaligned inlined functions. While we're at it, fix the types of some of the variables that end up getting returns from these functions.

2011-01-20cifs: mangle existing header for SMB_COM_NT_CANCELJeff Layton
The NT_CANCEL command looks just like the original command, except for a few small differences. The send_nt_cancel function however currently takes a tcon, which we don't have in SendReceive and SendReceive2. Instead of "respinning" the entire header for an NT_CANCEL, just mangle the existing header by replacing just the fields we need. This means we don't need a tcon and allows us to call it from other places.

2011-01-20[CIFS] cifs: reconnect unresponsive serversSteve French
If the server isn't responding to echoes, we don't want to leave tasks hung waiting for it to reply. At that point, we'll want to reconnect so that soft mounts can return an error to userspace quickly. If the client hasn't received a reply after a specified number of echo intervals, assume that the transport is down and attempt to reconnect the socket. The number of echo_intervals to wait before attempting to reconnect is tunable via a module parameter. Setting it to 0, means that the client will never attempt to reconnect. The default is 5.

2011-01-20cifs: allow for different handling of received responseJeff Layton
In order to incorporate async requests, we need to allow for a more general way to do things on receive, rather than just waking up a process. Turn the task pointer in the mid_q_entry into a callback function and a generic data pointer. When a response comes in, or the socket is reconnected, cifsd can call the callback function in order to wake up the process. The default is to just wake up the current process which should mean no change in behavior for existing code. Also, clean up the locking in cifs_reconnect. There doesn't seem to be any need to hold both the srv_mutex and GlobalMid_Lock when walking the list of mids.

2011-01-20cifs: don't reconnect server when we don't get a responseJeff Layton
We only want to force a reconnect to the server under very limited and specific circumstances. Now that we have processes waiting indefinitely for responses, we shouldn't reach this point unless a reconnect is already in process. Thus, there's no reason to re-mark the server for reconnect here.

2011-01-20cifs: wait indefinitely for responsesJeff Layton
The client should not be timing out on individual SMB requests. Too much of the state between client and server is tied to the state of the socket. If we time out requests and issue spurious disconnects then that comprimises data integrity. Instead of doing this complicated dance where we try to decide how long to wait for a response for particular requests, have the client instead wait indefinitely for a response. Also, use a TASK_KILLABLE sleep here so that fatal signals will break out of this waiting. Later patches will add support for detecting dead peers and forcing reconnects based on that.

2011-01-19cifs: don't fail writepages on -EAGAIN errorsJeff Layton
If CIFSSMBWrite2 returns -EAGAIN, then the error should be considered temporary. CIFS should retry the write instead of setting an error on the mapping and returning. For WB_SYNC_ALL, just retry the write immediately. In the WB_SYNC_NONE case, call redirty_page_for_writeback on all of the pages that didn't get written out and then move on. Also, fix up the handling of a short write with a successful return code. MS-CIFS says that 0 bytes_written means ENOSPC or EFBIG. It doesn't mention what a short, but non-zero write means, so for now treat it as we would an -EAGAIN return.

2011-01-18MIPS: Add initial support for the Atheros AR71XX/AR724X/AR931X SoCsGabor Juhos
This patch adds initial support for various Atheros SoCs based on the MIPS 24Kc core. The following models are supported at the moment: - AR7130 - AR7141 - AR7161 - AR9130 - AR9132 - AR7240 - AR7241 - AR7242 The current patch contains minimal support only, but the resulting kernel can boot into user-space with using of an initramfs image on various boards which are using these SoCs. Support for more built-in devices and individual boards will be implemented in further patches.
