rxrpc: Add bits for kernel services
Here are some patches that add a few things for kernel services to use:
(1) Allow service upgrade to be requested and allow the resultant actual
service ID to be obtained.
(2) Allow the RTT time of a call to be obtained.
(3) Allow a kernel service to find out if a call is still alive on a
server between transmitting a request and getting the reply.
(4) Allow data transmission to ignore signals if transmission progress is
being made in reasonable time. This is also usable by userspace by
passing MSG_WAITALL to sendmsg()[*].
[*] I'm not sure this is the right interface for this or whether a sockopt
should be used instead.

Add fallback compatibility strings for R-Car Gen 1 and 2.
In the case of Renesas R-Car hardware we know that there are generations of
SoCs, f.e. Gen 1 and 2. But beyond that its not clear what the relationship
between IP blocks might be. For example, I believe that r8a7790 is older
than r8a7791 but that doesn't imply that the latter is a descendant of the
former or vice versa.
We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.
For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme is being adopted for
drivers for Renesas SoCs.
Note that R-Car Gen2 and RZ/G1 have many compatible IP blocks. The
approach that has been consistently taken for other IP blocks is to name
common code, compatibility strings and so on after R-Car Gen2.

Make AF_RXRPC accept MSG_WAITALL as a flag to sendmsg() to tell it to
ignore signals whilst loading up the message queue, provided progress is
being made in emptying the queue at the other side.
Progress is defined as the base of the transmit window having being
advanced within 2 RTT periods. If the period is exceeded with no progress,
sendmsg() will return anyway, indicating how much data has been copied, if
any.
Once the supplied buffer is entirely decanted, the sendmsg() will return.

Provide a couple of functions to allow cleaner handling of signals in a
kernel service. They are:
(1) rxrpc_kernel_get_rtt()
This allows the kernel service to find out the RTT time for a call, so
as to better judge how large a timeout to employ.
Note, though, that whilst this returns a value in nanoseconds, the
timeouts can only actually be in jiffies.
(2) rxrpc_kernel_check_life()
This returns a number that is updated when ACKs are received from the
peer (notably including PING RESPONSE ACKs which we can elicit by
sending PING ACKs to see if the call still exists on the server).
The caller should compare the numbers of two calls to see if the call
is still alive.
These can be used to provide an extending timeout rather than returning
immediately in the case that a signal occurs that would otherwise abort an
RPC operation. The timeout would be extended if the server is still
responsive and the call is still apparently alive on the server.
For most operations this isn't that necessary - but for FS.StoreData it is:
OpenAFS writes the data to storage as it comes in without making a backup,
so if we immediately abort it when partially complete on a CTRL+C, say, we
have no idea of the state of the file after the abort.

Provide support for a kernel service to make use of the service upgrade
facility. This involves:
(1) Pass an upgrade request flag to rxrpc_kernel_begin_call().
(2) Make rxrpc_kernel_recv_data() return the call's current service ID so
that the caller can detect service upgrade and see what the service
was upgraded to.

Parsing and building C structures from a regdb is no longer needed
since the "firmware" file (regulatory.db) can be linked into the
kernel image to achieve the same effect.
Signed-off-by: Johannes Berg <johannes.berg@intel.com>
As the current regulatory database is only about 4k big, and already
difficult to extend, we decided that overall it would be better to
get rid of the complications with CRDA and load the database into the
kernel directly, but in a new format that is extensible.
The new file format can be extended since it carries a length field
on all the structs that need to be extensible.
In order to be able to request firmware when the module initializes,
move cfg80211 from subsys_initcall() to the later fs_initcall(); the
firmware loader is at the same level but linked earlier, so it can
be called from there. Otherwise, when both the firmware loader and
cfg80211 are built-in, the request will crash the kernel. We also
need to be before device_initcall() so that cfg80211 is available
for devices when they initialize.

There are three important fields that indicate the overall health and
status of an array: dev_health, sync_ratio, and sync_action. They tell
us the condition of the devices in the array, and the degree to which
the array is synchronized.
This commit fixes a condition that is reported incorrectly. When a member
of the array is being rebuilt or a new device is added, the "recover"
process is used to synchronize it with the rest of the array. When the
process is complete, but the sync thread hasn't yet been reaped, it is
possible for the state of MD to be:
mddev->recovery = [ MD_RECOVERY_RUNNING MD_RECOVERY_RECOVER MD_RECOVERY_DONE ]
curr_resync_completed = <max dev size> (but not MaxSector)
and all rdevs to be In_sync.
This causes the 'array_in_sync' output parameter that is passed to
rs_get_progress() to be computed incorrectly and reported as 'false' --
or not in-sync. This in turn causes the dev_health status characters to
be reported as all 'a', rather than the proper 'A'.
This can cause erroneous output for several seconds at a time when tools
will want to be checking the condition due to events that are raised at
the end of a sync process. Fix this by properly calculating the
'array_in_sync' return parameter in rs_get_progress().
Also, remove an unnecessary intermediate 'recovery_cp' variable in
rs_get_progress().

Enforcing exclusive ownership on upper/work dirs caused a docker
regression: https://github.com/moby/moby/issues/34672.
Euan spotted the regression and pointed to the offending commit.
Vivek has brought the regression to my attention and provided this
reproducer:
Terminal 1:
mount -t overlay -o workdir=work,lowerdir=lower,upperdir=upper none
merged/
Terminal 2:
unshare -m
Terminal 1:
umount merged
mount -t overlay -o workdir=work,lowerdir=lower,upperdir=upper none
merged/
mount: /root/overlay-testing/merged: none already mounted or mount point
busy
To fix the regression, I replaced the error with an alarming warning.
With index feature enabled, mount does fail, but logs a suggestion to
override exclusive dir protection by disabling index.
Note that index=off mount does take the inuse locks, so a concurrent
index=off will issue the warning and a concurrent index=on mount will fail.
Documentation was updated to reflect this change.

Our first batch of fixes this release cycle, unfortunately a bit noisier
than usual. Two major groups stand out:
- Some pinctril dts/dtsi changes for stm32 due to a new driver being
merged during the merge window, and this aligns the DT contents between
the old format and the new. This could arguably be moved to the next
merge window but it also seemed relatively harmless to include now.
- Amlogic/meson had driver changes merged that required devicetree
changes to avoid functional/performance regressions. I've already
asked them to be more careful about this going forward, and making
sure drivers are compatible with older DTs when they make these kind
of changes. The platform is actively being upstreamed so there's a
few things in flight, we've seen this happen before and sometimes
it's hard to catch in time.
Besides that there is the usual mix of minor fixes.

changes to avoid functional/performance regressions. I've already
asked them to be more careful about this going forward, and making
sure drivers are compatible with older DTs when they make these
kind of changes. The platform is actively being upstreamed so
there's a few things in flight, we've seen this happen before and
sometimes it's hard to catch in time.
Besides that there is the usual mix of minor fixes"

On Armada 7K/8K we need to explicitly enable the bus clock. The bus clock
is optional because not all the SoCs need them but at least for Armada
7K/8K it is actually mandatory.
The binding documentation is updating accordingly.
Without this patch the kernel hand during boot if the mvpp2.2 network
driver was not present in the kernel. Indeed the clock needed by the
xenon controller was set by the network driver.

Here are a few small fixes for 4.14-rc4.
The removal of DRIVER_ATTR() was almost completed by 4.14-rc1, but one
straggler made it in through some other tree (odds are, one of mine...)
So there's a simple removal of the last user, and then finally the macro
is removed from the tree.
There's a fix for old crazy udev instances that insist on reloading a
module when it is removed from the kernel due to the new uevents for
bind/unbind. This fixes the reported regression, hopefully some year in
the future we can drop the workaround, once users update to the latest
version, but I'm not holding my breath.
And then there's a build fix for a linker warning, and a buffer overflow
fix to match the PCI fixes you took through the PCI tree in the same
area.
All of these have been in linux-next for a few weeks while I've been

ThunderboltIP is a protocol created by Apple to tunnel IP/ethernet
traffic over a Thunderbolt cable. The protocol consists of configuration
phase where each side sends ThunderboltIP login packets (the protocol is
determined by UUID in the XDomain packet header) over the configuration
channel. Once both sides get positive acknowledgment to their login
packet, they configure high-speed DMA path accordingly. This DMA path is
then used to transmit and receive networking traffic.
This patch creates a virtual ethernet interface the host software can
use in the same way as any other networking interface. Once the
interface is brought up successfully network packets get tunneled over
the Thunderbolt cable to the remote host and back.
The connection is terminated by sending a ThunderboltIP logout packet
over the configuration channel. We do this when the network interface is
brought down by user or the driver is unloaded.

When two hosts are connected over a Thunderbolt cable, there is a
protocol they can use to communicate capabilities supported by the host.
The discovery protocol uses automatically configured control channel
(ring 0) and is build on top of request/response transactions using
special XDomain primitives provided by the Thunderbolt base protocol.
The capabilities consists of a root directory block of basic properties
used for identification of the host, and then there can be zero or more
directories each describing a Thunderbolt service and its capabilities.
Once both sides have discovered what is supported the two hosts can
setup high-speed DMA paths and transfer data to the other side using
whatever protocol was agreed based on the properties. The software
protocol used to communicate which DMA paths to enable is service
specific.
This patch adds support for the XDomain discovery protocol to the
Thunderbolt bus. We model each remote host connection as a Linux XDomain
device. For each Thunderbolt service found supported on the XDomain
device, we create Linux Thunderbolt service device which Thunderbolt
service drivers can then bind to based on the protocol identification
information retrieved from the property directory describing the
service.
This code is based on the work done by Amir Levy and Michael Jamet.

Use integers (reg property) to tell the number of the LED to the driver
instead of the node name. While both of these approaches are currently
used by the LED bindings, using integers will require less driver changes
for ACPI support. Additionally, it will make possible LED naming using
chip and LED node names, effectively making the label property most useful
for human-readable names only.

This function hasn't been used since the removal of iwmc3200wifi
in 2012. It also appears to have a bug when qos=True, since then
it'll copy uninitialized stack memory to the SKB.
Just remove the function entirely.

Currently, writing into
net.ipv6.conf.all.{accept_dad,use_optimistic,optimistic_dad} has no effect.
Fix handling of these flags by:
- using the maximum of global and per-interface values for the
accept_dad flag. That is, if at least one of the two values is
non-zero, enable DAD on the interface. If at least one value is
set to 2, enable DAD and disable IPv6 operation on the interface if
MAC-based link-local address was found
- using the logical OR of global and per-interface values for the
optimistic_dad flag. If at least one of them is set to one, optimistic
duplicate address detection (RFC 4429) is enabled on the interface
- using the logical OR of global and per-interface values for the
use_optimistic flag. If at least one of them is set to one,
optimistic addresses won't be marked as deprecated during source address
selection on the interface.
While at it, as we're modifying the prototype for ipv6_use_optimistic_addr(),
drop inline, and let the compiler decide.

Commit 446810f2dd ("of: add vendor prefix for Abracon Corporation")
claimed that "abcn" was used as the vendor prefix while in fact "abracon"
was used in the subsequent commits. It is also the only prefix used in the
tree.
