Commit
faee47cdbfe8d74a1573c2f81ea6dbb08d735be6
(sctp: Fix the RTO-doubling on idle-link heartbeats)
broke the RTO doubling for data retransmits. If the
heartbeat was sent before the data T3-rtx time, the
the RTO will not double upon the T3-rtx expiration.
Distingish between the operations by passing an argument
to the function.
Additionally, Wei Youngjun pointed out that our treatment
of requested HEARTBEATS and timer HEARTBEATS is the same
wrt resetting congestion window. That needs to be separated,
since user requested HEARTBEATS should not treat the link
as idle.

wimax/i2400m: implement RX reorder support
Allow the device to give the driver RX data with reorder information.
When that is done, the device will indicate the driver if a packet has
to be held in a (sorted) queue. It will also tell the driver when held
packets have to be released to the OS.
This is done to improve the WiMAX-protocol level retransmission
support when missing frames are detected.
The code docs provide details about the implementation.
In general, this just hooks into the RX path in rx.c; if a packet with
the reorder bit in the RX header is detected, the reorder information
in the header is extracted and one of the four main reorder operations
are executed. In one case (queue) no packet will be delivered to the
networking stack, just queued, whereas in the others (reset, update_ws
and queue_update_ws), queued packet might be delivered depending on
the window start for the specific queue.
The modifications to files other than rx.c are:
- control.c: during device initialization, enable reordering support
if the rx_reorder_disabled module parameter is not enabled
- driver.c: expose a rx_reorder_disable module parameter and call
i2400m_rx_setup/release() to initialize/shutdown RX reorder
support.
- i2400m.h: introduce members in 'struct i2400m' needed for
implementing reorder support.
- linux/i2400m.h: introduce TLVs, commands and constant definitions
related to RX reorder
Last but not least, the rx reorder code includes an small circular log
where the last N reorder operations are recorded to be displayed in
case of inconsistency. Otherwise diagnosing issues would be almost
impossible.

wimax/i2400m: support extended data RX protocol (no need to reallocate skbs)
Newer i2400m firmwares (>= v1.4) extend the data RX protocol so that
each packet has a 16 byte header. This header is mainly used to
implement host reordeing (which is addressed in later commits).
However, this header also allows us to overwrite it (once data has
been extracted) with an Ethernet header and deliver to the networking
stack without having to reallocate the skb (as it happened in fw <=
v1.3) to make room for it.
- control.c: indicate the device [dev_initialize()] that the driver
wants to use the extended data RX protocol. Also involves adding the
definition of the needed data types in include/linux/wimax/i2400m.h.
- rx.c: handle the new payload type for the extended RX data
protocol. Prepares the skb for delivery to
netdev.c:i2400m_net_erx().
- netdev.c: Introduce i2400m_net_erx() that adds the fake ethernet
address to a prepared skb and delivers it to the networking
stack.
- cleanup: in most instances in rx.c, the variable 'single' was
renamed to 'single_last' for it better conveys its meaning.

wimax/i2400m: allow control of the base-station idle mode timeout
For power saving reasons, WiMAX links can be put in idle mode while
connected after a certain time of the link not being used for tx or
rx. In this mode, the device pages the base-station regularly and when
data is ready to be transmitted, the link is revived.
This patch allows the user to control the time the device has to be
idle before it decides to go to idle mode from a sysfs
interace.
It also updates the initialization code to acknowledge the module
variable 'idle_mode_disabled' when the firmware is a newer version
(upcoming 1.4 vs 2.6.29's v1.3).
The method for setting the idle mode timeout in the older firmwares is
much more limited and can be only done at initialization time. Thus,
the sysfs file will return -ENOSYS on older ones.

wimax/i2400m: drop support for deprecated major fw interface, add for new minor
Firmware interface version 8.x.x has long been deprecated and is no
longer supported (nor available, as it is a preproduction firmware),
so it can be safely dropped.
Add support for firmware interface v9.2.x (current is 9.1.x). Firmware
version 9.2.x is backwards compatible with 9.1.x; new features are
enabled if switches are pressed to turn them on. Forthcoming commits
to the driver will start pressing those switches when the firmware
interface supports it.

wimax/i2400m: add the ability to fallback to other firmware files if the default is not there
In order to support backwards compatibility with older firmwares when
a driver is updated by a new kernel release, the i2400m bus drivers
can declare a list of firmware files they can work with (in general
these will be each a different version). The firmware loader will try
them in sequence until one loads.
Thus, if a user doesn't have the latest and greatest firmware that a
newly installed kernel would require, the driver would fall back to
the firmware from a previous release.
To support this, the i2400m->bus_fw_name is changed to be a NULL
terminated array firmware file names (and renamed to bus_fw_names) and
we add a new entry (i2400m->fw_name) that points to the name of the
firmware being currently used. All code that needs to print the
firmware file name uses i2400m->fw_name instead of the old
i2400m->bus_fw_name.
The code in i2400m_dev_bootstrap() that loads the firmware is changed
with an iterator over the firmware file name list that tries to load
each form user space, using the first one that succeeds in
request_firmware() (and thus stopping the iteration).
The USB and SDIO bus drivers are updated to take advantage of this and
reflect which firmwares they support.

dccp: Do not let initial option overhead shrink the MPS
This fixes a problem caused by the overlap of the connection-setup and
established-state phases of DCCP connections.
During connection setup, the client retransmits Confirm Feature-Negotiation
options until a response from the server signals that it can move from the
half-established PARTOPEN into the OPEN state, whereupon the connection is
fully established on both ends (RFC 4340, 8.1.5).
However, since the client may already send data while it is in the PARTOPEN
state, consequences arise for the Maximum Packet Size: the problem is that the
initial option overhead is much higher than for the subsequent established
phase, as it involves potentially many variable-length list-type options
(server-priority options, RFC 4340, 6.4).
Applying the standard MPS is insufficient here: especially with larger
payloads this can lead to annoying, counter-intuitive EMSGSIZE errors.
On the other hand, reducing the MPS available for the established phase by
the added initial overhead is highly wasteful and inefficient.
The solution chosen therefore is a two-phase strategy:
If the payload length of the DataAck in PARTOPEN is too large, an Ack is sent
to carry the options, and the feature-negotiation list is then flushed.
This means that the server gets two Acks for one Response. If both Acks get
lost, it is probably better to restart the connection anyway and devising yet
another special-case does not seem worth the extra complexity.
The result is a higher utilisation of the available packet space for the data
transmission phase (established state) of a connection.
The patch (over-)estimates the initial overhead to be 32*4 bytes -- commonly
seen values were around 90 bytes for initial feature-negotiation options.
It uses sizeof(u32) to mean "aligned units of 4 bytes".
For consistency, another use of 4-byte alignment is adapted.

dccp: Minimise header option overhead in setting the MPS
This patch resolves a long-standing FIXME to dynamically update the Maximum
Packet Size depending on actual options usage.
It uses the flags set by the feature-negotiation infrastructure to compute
the required header option size.
Most options are fixed-size, a notable exception are Ack Vectors (required
currently only by CCID-2). These can have any length between 3 and 1020
bytes. As a result of testing, 16 bytes (2 bytes for type/length plus 14 Ack
Vector cells) have been found to be sufficient for loss-free situations.
There are currently no CCID-specific header options which may appear on data
packets, thus it is not necessary to define a corresponding CCID field as
suggested in the old comment.

Fix FREEZE/THAW compat_ioctl regression
Commit
8e961870bb9804110d5c8211d5d9d500451c4518 removed the FREEZE/THAW
handling in xfs_compat_ioctl but never added any compat handler back, so
now any freeze/thaw request from a 32-bit binary ond 64-bit userspace
will fail.
As these ioctls are 32/64-bit compatible two simple COMPATIBLE_IOCTL
entries in fs/compat_ioctl.c will do the job.
