This patch replaces skb_recv_datagram() with an open-coded variant of it
releasing the socket lock before the __skb_wait_for_more_packets() call
and re-acquiring it after such call in order that other functions that
need socket lock could be executed.
what's more, the socket lock will be released only when recvmsg() will
block and that should produce nicer overall behavior.

net: usb: ax88179_178a needs FLAG_SEND_ZLP
The extra byte inserted by usbnet.c when
(length % dev->maxpacket == 0) is causing problems to device.
This patch sets FLAG_SEND_ZLP to avoid this.
Tested with: 0b95:1790 ASIX Electronics Corp. AX88179 Gigabit Ethernet
Problems observed:
======================================================================
1) Using ssh/sshfs. The remote sshd daemon can abort with the message:
"message authentication code incorrect"
This happens because the tcp message sent is corrupted during the
USB "Bulk out". The device calculate the tcp checksum and send a
valid tcp message to the remote sshd. Then the encryption detects
the error and aborts.
2) NETDEV WATCHDOG: ... (ax88179_178a): transmit queue 0 timed out
3) Stop normal work without any log message.
The "Bulk in" continue receiving packets normally.
The host sends "Bulk out" and the device responds with -ECONNRESET.
(The netusb.c code tx_complete ignore -ECONNRESET)
Under normal conditions these errors take days to happen and in
intense usage take hours.
A test with ping gives packet loss, showing that something is wrong:
ping -4 -s 462 {destination} # 462 = 512 - 42 - 8
Not all packets fail.
My guess is that the device tries to find another packet starting
at the extra byte and will fail or not depending on the next
bytes (old buffer content).

[Why]
For OLED eDP the Display Manager uses max_cll value as a limit
for brightness control.
max_cll defines the content light luminance for individual pixel.
Whereas max_fall defines frame-average level luminance.
The user may not observe the difference in brightness in between
max_fall and max_cll.
That negatively impacts the user experience.
[How]
Use max_fall value instead of max_cll as a limit for brightness control.

Disable VF's RX/TX queues, when it's disabled. VF can have queues enabled,
when it requests a reset. If PF driver assumes that VF is disabled,

In this scenario VF should not have RX/TX queues enabled. If PF failed
to set up VF's queues, VF will reset due to TX timeouts in VF driver.
Initialize iterator 'i' to -1, so if error happens prior to configuring

mlxsw: spectrum_cnt: Reorder counter pools
Both RIF and ACL flow counters use a 24-bit SW-managed counter address to
communicate which counter they want to bind.
In a number of Spectrum FW releases, binding a RIF counter is broken and
slices the counter index to 16 bits. As a result, on Spectrum-2 and above,
no more than about 410 RIF counters can be effectively used. This
translates to 205 netdevices for which L3 HW stats can be enabled. (This
does not happen on Spectrum-1, because there are fewer counters available
overall and the counter index never exceeds 16 bits.)
Binding counters to ACLs does not have this issue. Therefore reorder the
counter allocation scheme so that RIF counters come first and therefore get
lower indices that are below the 16-bit barrier.

drm/exynos: mic: Rework initialization
Commit
dd8b6803bc49 ("exynos: drm: dsi: Attach in_bridge in MIC driver")
moved Exynos MIC attaching from DSI to MIC driver. However the method
proposed there is incomplete and cannot really work. To properly attach
it to the bridge chain, access to the respective encoder is needed. The
Exynos MIC driver always attaches to the encoder created by the Exynos
DSI driver, so grab it via available helpers for getting access to the
CRTC and encoders. This also requires to change the order of driver
component binding to let DSI to be bound before MIC.

fs: account for group membership
When calling setattr_prepare() to determine the validity of the
attributes the ia_{g,u}id fields contain the value that will be written
to inode->i_{g,u}id. This is exactly the same for idmapped and
non-idmapped mounts and allows callers to pass in the values they want
to see written to inode->i_{g,u}id.
When group ownership is changed a caller whose fsuid owns the inode can
change the group of the inode to any group they are a member of. When
searching through the caller's groups we need to use the gid mapped
according to the idmapped mount otherwise we will fail to change
ownership for unprivileged users.
Consider a caller running with fsuid and fsgid 1000 using an idmapped
mount that maps id 65534 to 1000 and 65535 to 1001. Consequently, a file
owned by 65534:65535 in the filesystem will be owned by 1000:1001 in the
idmapped mount.
The caller now requests the gid of the file to be changed to 1000 going
through the idmapped mount. In the vfs we will immediately map the
requested gid to the value that will need to be written to inode->i_gid
and place it in attr->ia_gid. Since this idmapped mount maps 65534 to
1000 we place 65534 in attr->ia_gid.
When we check whether the caller is allowed to change group ownership we
first validate that their fsuid matches the inode's uid. The
inode->i_uid is 65534 which is mapped to uid 1000 in the idmapped mount.
Since the caller's fsuid is 1000 we pass the check.
We now check whether the caller is allowed to change inode->i_gid to the
requested gid by calling in_group_p(). This will compare the passed in
gid to the caller's fsgid and search the caller's additional groups.
Since we're dealing with an idmapped mount we need to pass in the gid
mapped according to the idmapped mount. This is akin to checking whether
a caller is privileged over the future group the inode is owned by. And
that needs to take the idmapped mount into account. Note, all helpers
are nops without idmapped mounts.
New regression test sent to xfstests.

net: axienet: fix DMA Tx error
We ran into multiple DMA TX errors while writing files over a network
block device running on top of a DMA-connected AXI Ethernet device on
64-bit RISC-V machines. The errors indicated that the DMA had fetched a
null descriptor and we found that the reason for this is that AXI DMA had
unexpectedly processed a partially updated tail descriptor pointer. To
fix it, we suggest that the driver should use one 64-bit write instead
of two 32-bit writes to perform such update if possible. For those
archectures where double-word load/stores are unavailable, e.g. 32-bit
archectures, force a driver probe failure if the driver finds 64-bit
capability on DMA.

net: axienet: Use iowrite64 to write all 64b descriptor pointers
According to commit
f735c40ed93c ("net: axienet: Autodetect 64-bit DMA
capability") and AXI-DMA spec (pg021), on 64-bit capable dma, only
writing MSB part of tail descriptor pointer causes DMA engine to start
fetching descriptors. However, we found that it is true only if dma is in
idle state. In other words, dma would use a tailp even if it only has LSB
updated, when the dma is running.
The non-atomicity of this behavior could be problematic if enough
delay were introduced in between the 2 writes. For example, if an
interrupt comes right after the LSB write and the cpu spends long
enough time in the handler for the dma to get back into idle state by
completing descriptors, then the seconcd write to MSB would treat dma
to start fetching descriptors again. Since the descriptor next to the
one pointed by current tail pointer is not filled by the kernel yet,
fetching a null descriptor here causes a dma internal error and halt
the dma engine down.
We suggest that the dma engine should start process a 64-bit MMIO write
to the descriptor pointer only if ONE 32-bit part of it is written on all
states. Or we should restrict the use of 64-bit addressable dma on 32-bit
platforms, since those devices have no instruction to guarantee the write
to LSB and MSB part of tail pointer occurs atomically to the dma.

curp = x-3;

net: axienet: make the 64b addresable DMA depends on 64b archectures
Currently it is not safe to config the IP as 64-bit addressable on 32-bit

pointers. The pointer is 64-bit wide if the IP is configured as 64-bit,
and the device would process the partially updated pointer on some
states if the pointer was updated via two store-words. To prevent such
condition, we force a probe fail if we discover that the IP has 64-bit

Pull random number generator fixes from Jason Donenfeld:
- A fix for a 5.19 regression for a case in which early device tree
initializes the RNG, which flips a static branch.
On most plaforms, jump labels aren't initialized until much later, so
this caused splats. On a few mailing list threads, we cooked up easy
fixes for arm64, arm32, and risc-v. But then things looked slightly
more involved for xtensa, powerpc, arc, and mips. And at that point,
when we're patching 7 architectures in a place before the console is
even available, it seems like the cost/risk just wasn't worth it.
So random.c works around it now by checking the already exported
`static_key_initialized` boolean, as though somebody already ran into
this issue in the past. I'm not super jazzed about that; it'd be
prettier to not have to complicate downstream code. But I suppose
it's practical.
- A few small code nits and adding a missing __init annotation.
- A change to the default config values to use the cpu and bootloader's
seeds for initializing the RNG earlier.
This brings them into line with what all the distros do (Fedora/RHEL,
Debian, Ubuntu, Gentoo, Arch, NixOS, Alpine, SUSE, and Void... at
least), and moreover will now give us test coverage in various test
beds that might have caught the above device tree bug earlier.
- A change to WireGuard CI's configuration to increase test coverage
around the RNG.
- A documentation comment fix to unrelated maintainerless CRC code that
I was asked to take, I guess because it has to do with polynomials
(which the RNG thankfully no longer uses).

The original code created a buffer size of 128 bytes regardless if
the WMI call required a smaller buffer or not. This particular
behavior occurs in older BIOS and reproduced in OMEN laptops. Newer
BIOS handles buffer sizes properly and meets the latest specification
requirements. This is the reason why testing with a dynamically
allocated buffer did not uncover any failures with the test systems at
hand.
This patch was tested on several OMEN, Elite, and Zbooks. It was
confirmed the patch resolves HPWMI_FAN GET/SET calls in an OMEN
Laptop 15-ek0xxx. No problems were reported when testing on several Elite
and Zbooks notebooks.

iov_iter: fix build issue due to possible type mis-match
Commit
6c77676645ad ("iov_iter: Fix iter_xarray_get_pages{,_alloc}()")
introduced a problem on some 32-bit architectures (at least arm, xtensa,
csky,sparc and mips), that have a 'size_t' that is 'unsigned int'.
The reason is that we now do
min(nr * PAGE_SIZE - offset, maxsize);
where 'nr' and 'offset' and both 'unsigned int', and PAGE_SIZE is
'unsigned long'. As a result, the normal C type rules means that the
first argument to 'min()' ends up being 'unsigned long'.
In contrast, 'maxsize' is of type 'size_t'.
Now, 'size_t' and 'unsigned long' are always the same physical type in
the kernel, so you'd think this doesn't matter, and from an actual
arithmetic standpoint it doesn't.
But on 32-bit architectures 'size_t' is commonly 'unsigned int', even if
it could also be 'unsigned long'. In that situation, both are unsigned
32-bit types, but they are not the *same* type.
And as a result 'min()' will complain about the distinct types (ignore
the "pointer types" part of the error message: that's an artifact of the
way we have made 'min()' check types for being the same):
lib/iov_iter.c: In function 'iter_xarray_get_pages':
include/linux/minmax.h:20:35: error: comparison of distinct pointer types lacks a cast [-Werror]
20 | (!!(sizeof((typeof(x) *)1 == (typeof(y) *)1)))
| ^~
lib/iov_iter.c:1464:16: note: in expansion of macro 'min'
1464 | return min(nr * PAGE_SIZE - offset, maxsize);
| ^~~
This was not visible on 64-bit architectures (where we always define
'size_t' to be 'unsigned long').
Force these cases to use 'min_t(size_t, x, y)' to make the type explicit
and avoid the issue.
[ Nit-picky note: technically 'size_t' doesn't have to match 'unsigned
long' arithmetically. We've certainly historically seen environments
with 16-bit address spaces and 32-bit 'unsigned long'.
Similarly, even in 64-bit modern environments, 'size_t' could be its
own type distinct from 'unsigned long', even if it were arithmetically
identical.
So the above type commentary is only really descriptive of the kernel
environment, not some kind of universal truth for the kinds of wild
and crazy situations that are allowed by the C standard ]

wireguard: selftests: use maximum cpu features and allow rng seeding
By forcing the maximum CPU that QEMU has available, we expose additional
capabilities, such as the RNDR instruction, which increases test
coverage. This then allows the CI to skip the fake seeding step in some
cases. Also enable STRICT_KERNEL_RWX to catch issues related to early
jump labels when the RNG is initialized at boot.

iov_iter: Fix iter_xarray_get_pages{,_alloc}()
The maths at the end of iter_xarray_get_pages() to calculate the actual
size doesn't work under some circumstances, such as when it's been asked to
extract a partial single page. Various terms of the equation cancel out
and you end up with actual == offset. The same issue exists in
iter_xarray_get_pages_alloc().
Fix these to just use min() to select the lesser amount from between the
amount of page content transcribed into the buffer, minus the offset, and
the size limit specified.
This doesn't appear to have caused a problem yet upstream because network
filesystems aren't getting the pages from an xarray iterator, but rather
passing it directly to the socket, which just iterates over it. Cachefiles
*does* do DIO from one to/from ext4/xfs/btrfs/etc. but it always asks for
whole pages to be written or read.

netfs: Further cleanups after struct netfs_inode wrapper introduced
Change the signature of netfs helper functions to take a struct netfs_inode
pointer rather than a struct inode pointer where appropriate, thereby
relieving the need for the network filesystem to convert its internal inode
format down to the VFS inode only for netfslib to bounce it back up. For
type safety, it's better not to do that (and it's less typing too).
Give netfs_write_begin() an extra argument to pass in a pointer to the
netfs_inode struct rather than deriving it internally from the file
pointer. Note that the ->write_begin() and ->write_end() ops are intended
to be replaced in the future by netfslib code that manages this without the
need to call in twice for each page.
netfs_readpage() and similar are intended to be pointed at directly by the
address_space_operations table, so must stick to the signature dictated by
the function pointers there.
