By default, the switch driver is expected to configure CPU and DSA
ports to their maximum speed. For the 6341 and 6390 families, the
ports interface mode has to be configured as well. The 6390X range
support 10G ports using XAUI, while the 6341 and 6390 supports
2500BaseX, as their maximum speed.

rxrpc_get_client_conn() adds a new call to the front of the waiting_calls
queue if the connection it's going to use already exists. This is bad as
it allows calls to get starved out.
Fix this by adding to the tail instead.
Also change the other enqueue point in the same function to put it on the
front (ie. when we have a new connection). This makes the point that in
the case of a new connection the new call goes at the front (though it
doesn't actually matter since the queue should be unoccupied).

Commit 7716682cc5 ("tcp/dccp: fix another race at listener
dismantle") let inet_csk_reqsk_queue_add() fail, and adjusted
{tcp,dccp}_check_req() accordingly. However, TFO and syncookies
weren't modified, thus leaking allocated resources on error.
Contrary to tcp_check_req(), in both syncookies and TFO cases,
we need to drop the request socket. Also, since the child socket is
created with inet_csk_clone_lock(), we have to unlock it and drop an
extra reference (->sk_refcount is initially set to 2 and
inet_csk_reqsk_queue_add() drops only one ref).
For TFO, we also need to revert the work done by tcp_try_fastopen()
(with reqsk_fastopen_remove()).

Pull io_uring IO interface from Jens Axboe:
"Second attempt at adding the io_uring interface.
Since the first one, we've added basic unit testing of the three
system calls, that resides in liburing like the other unit tests that
we have so far. It'll take a while to get full coverage of it, but
we're working towards it. I've also added two basic test programs to
tools/io_uring. One uses the raw interface and has support for all the
various features that io_uring supports outside of standard IO, like
fixed files, fixed IO buffers, and polled IO. The other uses the
liburing API, and is a simplified version of cp(1).
This adds support for a new IO interface, io_uring.
io_uring allows an application to communicate with the kernel through
two rings, the submission queue (SQ) and completion queue (CQ) ring.
This allows for very efficient handling of IOs, see the v5 posting for
some basic numbers:
https://lore.kernel.org/linux-block/20190116175003.17880-1-axboe@kernel.dk/
Outside of just efficiency, the interface is also flexible and
extendable, and allows for future use cases like the upcoming NVMe
key-value store API, networked IO, and so on. It also supports async
buffered IO, something that we've always failed to support in the
kernel.
Outside of basic IO features, it supports async polled IO as well.
This particular feature has already been tested at Facebook months ago
for flash storage boxes, with 25-33% improvements. It makes polled IO
actually useful for real world use cases, where even basic flash sees
a nice win in terms of efficiency, latency, and performance. These
boxes were IOPS bound before, now they are not.
This series adds three new system calls. One for setting up an
io_uring instance (io_uring_setup(2)), one for submitting/completing
IO (io_uring_enter(2)), and one for aux functions like registrating
file sets, buffers, etc (io_uring_register(2)). Through the help of
Arnd, I've coordinated the syscall numbers so merge on that front
should be painless.
Jon did a writeup of the interface a while back, which (except for
minor details that have been tweaked) is still accurate. Find that
here:
https://lwn.net/Articles/776703/
Huge thanks to Al Viro for helping getting the reference cycle code
correct, and to Jann Horn for his extensive reviews focused on both
security and bugs in general.
There's a userspace library that provides basic functionality for
applications that don't need or want to care about how to fiddle with
the rings directly. It has helpers to allow applications to easily set
up an io_uring instance, and submit/complete IO through it without
knowing about the intricacies of the rings. It also includes man pages
(thanks to Jeff Moyer), and will continue to grow support helper
functions and features as time progresses. Find it here:

auth_hmacs couldn't be set in sctp_endpoint_init().
It can even crash kernel by doing:
1. on server: sysctl -w net.sctp.auth_enable=1,
sysctl -w net.sctp.addip_enable=1,
sysctl -w net.sctp.addip_noauth_enable=0,
listen() on server,

2. on client: connect() to server.
3. on server: accept() the asoc,
sysctl -w net.sctp.auth_enable=1.
4. on client: send() asconf packet to server.

nfsd currently reports the NFSv3 dtpref FSINFO parameter
to be PAGE_SIZE, so NFS clients will typically ask for one
page of directory entries at a time. This is needlessly restrictive
as nfsd can handle larger replies easily.
Also, a READDIR request (but not a READDIRPLUS request) has the count
size clipped to PAGE_SIE, again unnecessary.
This patch lifts these limits so that larger readdir requests can be
used.

If we receive a packet while deleting a VXLAN device, there's a chance
vxlan_rcv() is called at the same time as vxlan_dellink(). This is fine,
except that vxlan_dellink() should never ever touch stuff that's still in
use, such as the GRO cells list.
Otherwise, vxlan_rcv() crashes while queueing packets via
gro_cells_receive().
Move the gro_cells_destroy() to vxlan_uninit(), which runs after the RCU
grace period is elapsed and nothing needs the gro_cells anymore.
This is now done in the same way as commit 8e816df879 ("geneve: Use GRO
cells infrastructure.") originally implemented for GENEVE.

rxrpc_disconnect_client_call() reads the call's connection ID protocol
value (call->cid) as part of that function's variable declarations. This
is bad because it's not inside the locked section and so may race with
someone granting use of the channel to the call.
This manifests as an assertion failure (see below) where the call in the
presumed channel (0 because call->cid wasn't set when we read it) doesn't
match the call attached to the channel we were actually granted (if 1, 2 or
3).
Fix this by moving the read and dependent calculations inside of the
channel_lock section. Also, only set the channel number and pointer
variables if cid is not zero (ie. unset).
This problem can be induced by injecting an occasional error in
rxrpc_wait_for_channel() before the call to schedule().
Make two further changes also:
(1) Add a trace for wait failure in rxrpc_connect_call().
(2) Drop channel_lock before BUG'ing in the case of the assertion failure.
The failure causes a trace akin to the following:
rxrpc: Assertion failed - 18446612685268945920(0xffff8880beab8c00) == 18446612685268621312(0xffff8880bea69800) is false

The race occurs in __mkroute_output() when 2 threads lookup a dst:
CPU A CPU B
find_exception()
find_exception() [fnhe expires]
ip_del_fnhe() [fnhe is deleted]
rt_bind_exception()
In rt_bind_exception() it will bind a deleted fnhe with the new dst, and
this dst will get no chance to be freed. It causes a dev defcnt leak and
consecutive dmesg warnings:
unregister_netdevice: waiting for ethX to become free. Usage count = 1
Especially thanks Jon to identify the issue.
This patch fixes it by setting fnhe_daddr to 0 in ip_del_fnhe() to stop
binding the deleted fnhe with a new dst when checking fnhe's fnhe_daddr
and daddr in rt_bind_exception().
It works as both ip_del_fnhe() and rt_bind_exception() are protected by
fnhe_lock and the fhne is freed by kfree_rcu().

Core changes:
- The big change this time around is the irqchip handling in
the qualcomm pin controllers, closely coupled with the
gpiochip. This rework, in a classic fall-between-the-chairs
fashion has been sidestepped for too long. The Qualcomm
IRQchips using the SPMI and SSBI transport mechanisms have
been rewritten to use hierarchical irqchip. This creates
the base from which I intend to gradually pull support for
hierarchical irqchips into the gpiolib irqchip helpers to
cut down on duplicate code. We have too many hacks in the
kernel because people have been working around the missing
hierarchical irqchip for years, and once it was there,
noone understood it for a while. We are now slowly adapting
to using it. This is why this pull requests include changes
to MFD, SPMI, IRQchip core and some ARM Device Trees
pertaining to the Qualcomm chip family. Since Qualcomm have
so many chips and such large deployments it is paramount
that this platform gets this right, and now it (hopefully)
does.
- Core support for pull-up and pull-down configuration, also
from the device tree. When a simple GPIO chip support a
"off or on" pull-up or pull-down resistor, we provide a
way to set this up using machine descriptors or device tree.
If more elaborate control of pull up/down (such as
resistance shunt setting) is required, drivers should be
phased over to use pin control. We do not yet provide a
userspace ABI for this pull up-down setting but I suspect
the makers are going to ask for it soon enough. PCA953x
is the first user of this new API.
- The GPIO mockup driver has been revamped after some
discussion improving the IRQ simulator in the process.
The idea is to make it possible to use the mockup for
both testing and virtual prototyping, e.g. when you do
not yet have a GPIO expander to play with but really
want to get something to develop code around before
hardware is available. It's neat. The blackbox testing
usecase is currently making its way into kernelci.
- ACPI GPIO core preserves non direction flags when updating
flags.
- A new device core helper for devm_platform_ioremap_resource()
is funneled through the GPIO tree with Greg's ACK.
New drivers:
- TQ-Systems QTMX86 GPIO controllers (using port-mapped
I/O)
- Gateworks PLD GPIO driver (vaccumed up from OpenWrt)
- AMD G-Series PCH (Platform Controller Hub) GPIO driver.
- Fintek F81804 & F81966 subvariants.
- PCA953x now supports NXP PCAL6416.
Driver improvements:
- IRQ support on the Nintendo Wii (Hollywood) GPIO.
- get_direction() support for the MVEBU driver.
- Set the right output level on SAMA5D2.
- Drop the unused irq trigger setting on the Spreadtrum
driver.
- Wakeup support for PCA953x.

Merge tag 'for-v5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-power-supply
Pull power supply and reset updates from Sebastian Reichel:
"Nothing too fancy in the power-supply subsystem this time. There are
less patches than usual, since I did not have enough time to review
them in time. The good news is, that all patches have been in
linux-next for more than two weeks and there are no complicated
cross-subsystem patchsets this time!
Summary:
- at91-reset: add sam9x60 support
- sc27xx: improve capacity logic
- goldfish_battery: enhance driver by adding many new properties
- isp1704: drop platform data and migrate to gpiod
- misc small fixes and improvements"

* Fix a use after free error in a certain error situation.
* Fix some flag handling issues in the SSIF (I2C) IPMI driver.
* A bunch of cleanups, spacing issues, converting pr_xxx to dev_xxx,
use standard UUID handling, and some other minor stuff.
* The IPMI code was creating a platform device if none was supplied.
Instead of doing that, have every source that creates an IPMI
device supply a device struct. This fixes several issues,including
a crash in one situation, and cleans things up a bit.

Commit f7c90c2aa4 ("x86/xen: don't write ptes directly in 32-bit
PV guests") introduced a regression for booting dom0 on huge systems
with lots of RAM (in the TB range).
Reason is that on those hosts the p2m list needs to be moved early in
the boot process and this requires temporary page tables to be created.
Said commit modified xen_set_pte_init() to use a hypercall for writing
a PTE, but this requires the page table being in the direct mapped
area, which is not the case for the temporary page tables used in
xen_relocate_p2m().
As the page tables are completely written before being linked to the
actual address space instead of set_pte() a plain write to memory can
be used in xen_relocate_p2m().
Fixes: f7c90c2aa4 ("x86/xen: don't write ptes directly in 32-bit PV guests")
