d63f11c02b gpiolib-acpi: Don't set GPIOs for wakeup in S3 mode
commit 1796f808e4 ("HID: i2c-hid: acpi: Stop setting wakeup_capable")
adjusted the policy to enable wakeup by default if the ACPI tables
indicated that a device was wake capable.

It was reported however that this broke suspend on at least two System76
systems in S3 mode and two Lenovo Gen2a systems, but only with S3.
When the machines are set to s2idle, wakeup behaves properly.

Configuring the GPIOs for wakeup with S3 doesn't work properly, so only
set it when the system supports low power idle.

4bdbba54e9 nfsd: don't free files unconditionally in __nfsd_file_cache_purge
nfsd_file_cache_purge is called when the server is shutting down, in
which case, tearing things down is generally fine, but it also gets
called when the exports cache is flushed.

Instead of walking the cache and freeing everything unconditionally,
handle it the same as when we have a notification of conflicting access.

2f62847cf6 ARM: 9287/1: Reduce __thumb2__ definition to crypto files that require it
Commit 1d2e9b67b0 ("ARM: 9265/1: pass -march= only to compiler") added
a __thumb2__ define to ASFLAGS to avoid build errors in the crypto code,
which relies on __thumb2__ for preprocessing. Commit 59e2cf8d21 ("ARM:
9275/1: Drop '-mthumb' from AFLAGS_ISA") followed up on this by removing
-mthumb from AFLAGS so that __thumb2__ would not be defined when the
default target was ARMv7 or newer.

Unfortunately, the second commit's fix assumes that the toolchain
defaults to -mno-thumb / -marm, which is not the case for Debian's
arm-linux-gnueabihf target, which defaults to -mthumb:

  $ echo | arm-linux-gnueabihf-gcc -dM -E - | grep __thumb
  #define __thumb2__ 1
  #define __thumb__ 1

This target is used by several CI systems, which will still see
redefined macro warnings, despite '-mthumb' not being present in the
flags:

  <command-line>: warning: "__thumb2__" redefined
  <built-in>: note: this is the location of the previous definition

Remove the global AFLAGS __thumb2__ define and move it to the crypto
folder where it is required by the imported OpenSSL algorithms; the rest
of the kernel should use the internal CONFIG_THUMB2_KERNEL symbol to
know whether or not Thumb2 is being used or not. Be sure that __thumb2__
is undefined first so that there are no macro redefinition warnings.

b00c51ef8f io_uring/net: cache provided buffer group value for multishot receives
If we're using ring provided buffers with multishot receive, and we end
up doing an io-wq based issue at some points that also needs to select
a buffer, we'll lose the initially assigned buffer group as
io_ring_buffer_select() correctly clears the buffer group list as the
issue isn't serialized by the ctx uring_lock. This is fine for normal
receives as the request puts the buffer and finishes, but for multishot,
we will re-arm and do further receives. On the next trigger for this
multishot receive, the receive will try and pick from a buffer group
whose value is the same as the buffer ID of the las receive. That is
obviously incorrect, and will result in a premature -ENOUFS error for
the receive even if we had available buffers in the correct group.

Cache the buffer group value at prep time, so we can restore it for
future receives. This only needs doing for the above mentioned case, but
just do it by default to keep it easier to read.

9f535c870e ipv6: fix reachability confirmation with proxy_ndp
When proxying IPv6 NDP requests, the adverts to the initial multicast
solicits are correct and working.  On the other hand, when later a
reachability confirmation is requested (on unicast), no reply is sent.

This causes the neighbor entry expiring on the sending node, which is
mostly a non-issue, as a new multicast request is sent.  There are
routers, where the multicast requests are intentionally delayed, and in
these environments the current implementation causes periodic packet
loss for the proxied endpoints.

The root cause is the erroneous decrease of the hop limit, as this
is checked in ndisc.c and no answer is generated when it's 254 instead
of the correct 255.

v1->v2:
I've decided to focus just on the MAC Merge layer for now, which is why
I am able to submit this patch set as non-RFC.
v1 (RFC) at:
https://patchwork.kernel.org/project/netdevbpf/cover/20220816222920.1952936-1-vladimir.oltean@nxp.com/

What is being introduced
------------------------

TL;DR: a MAC Merge layer as defined by IEEE 802.3-2018, clause 99
(interspersing of express traffic). This is controlled through ethtool
netlink (ETHTOOL_MSG_MM_GET, ETHTOOL_MSG_MM_SET). The raw ethtool
commands are posted here:
https://patchwork.kernel.org/project/netdevbpf/cover/20230111153638.1454687-1-vladimir.oltean@nxp.com/

The MAC Merge layer has its own statistics counters
(ethtool --include-statistics --show-mm swp0) as well as two member
MACs, the statistics of which can be queried individually, through a new
ethtool netlink attribute, corresponding to:

$ ethtool -I --show-pause eno2 --src aggregate
$ ethtool -S eno2 --groups eth-mac eth-phy eth-ctrl rmon -- --src pmac

The core properties of the MAC Merge layer are described in great detail
in patches 02/12 and 03/12. They can be viewed in "make htmldocs" format.

Devices for which the API is supported
--------------------------------------

I decided to start with the Ethernet switch on NXP LS1028A (Felix)
because of the smaller patch set. I also have support for the ENETC
controller pending.

I would like to get confirmation that the UAPI being proposed here will
not restrict any use cases known by other hardware vendors.

Why is support for preemptible traffic classes not here?
--------------------------------------------------------

There is legitimate concern whether the 802.1Q portion of the standard
(which traffic classes go to the eMAC and which to the pMAC) should be
modeled in Linux using tc or using another UAPI. I think that is
stalling the entire series, but should be discussed separately instead.
Removing FP adminStatus support makes me confident enough to submit this
patch set without an RFC tag (meaning: I wouldn't mind if it was merged
as is).

What is submitted here is sufficient for an LLDP daemon to do its job.
I've patched openlldp to advertise and configure frame preemption:
https://github.com/vladimiroltean/openlldp/tree/frame-preemption-v3

In case someone wants to try it out, here are some commands I've used.

 # Configure the interfaces to receive and transmit LLDP Data Units
 lldptool -L -i eno0 adminStatus=rxtx
 lldptool -L -i swp0 adminStatus=rxtx
 # Enable the transmission of certain TLVs on switch's interface
 lldptool -T -i eno0 -V addEthCap enableTx=yes
 lldptool -T -i swp0 -V addEthCap enableTx=yes
 # Query LLDP statistics on switch's interface
 lldptool -S -i swp0
 # Query the received neighbor TLVs
 lldptool -i swp0 -t -n -V addEthCap
 Additional Ethernet Capabilities TLV
         Preemption capability supported
         Preemption capability enabled
         Preemption capability active
         Additional fragment size: 60 octets

So using this patch set, lldpad will be able to advertise and configure
frame preemption, but still, no data packet will be sent as preemptible
over the link, because there is no UAPI to control which traffic classes
are sent as preemptible and which as express.

Preemptable or preemptible?
---------------------------

IEEE 802.3 uses "preemptable" throughout. IEEE 802.1Q uses "preemptible"
throughout. Because the definition of "preemptible" falls under 802.1Q's
jurisdiction and 802.3 just references it, I went with the 802.1Q naming
even where supporting an 802.3 feature. Also, checkpatch agrees with this.

7c494a7749 net: ethtool: netlink: introduce ethnl_update_bool()
Due to the fact that the kernel-side data structures have been carried
over from the ioctl-based ethtool, we are now in the situation where we
have an ethnl_update_bool32() function, but the plain function that
operates on a boolean value kept in an actual u8 netlink attribute
doesn't exist.

With new ethtool features that are exposed solely over netlink, the
kernel data structures will use the "bool" type, so we will need this
kind of helper. Introduce it now; it's needed for things like
verify-disabled for the MAC merge configuration.

e38553bdc3 net: fec: Use page_pool_put_full_page when freeing rx buffers
The page_pool_release_page was used when freeing rx buffers, and this
function just unmaps the page (if mapped) and does not recycle the page.
So after hundreds of down/up the eth0, the system will out of memory.
For more details, please refer to the following reproduce steps and
bug logs. To solve this issue and refer to the doc of page pool, the
page_pool_put_full_page should be used to replace page_pool_release_page.
Because this API will try to recycle the page if the page refcnt equal to
1. After testing 20000 times, the issue can not be reproduced anymore
(about testing 391 times the issue will occur on i.MX8MN-EVK before).

Reproduce steps:
Create the test script and run the script. The script content is as
follows:
LOOPS=20000
i=1
while [ $i -le $LOOPS ]
do
    echo "TINFO:ENET $curface up and down test $i times"
    org_macaddr=$(cat /sys/class/net/eth0/address)
    ifconfig eth0 down
    ifconfig eth0  hw ether $org_macaddr up
    i=$(expr $i + 1)
done
sleep 5
if cat /sys/class/net/eth0/operstate | grep 'up';then
    echo "TEST PASS"
else
    echo "TEST FAIL"
fi

a44b331614 KVM: x86/vmx: Do not skip segment attributes if unusable bit is set
When serializing and deserializing kvm_sregs, attributes of the segment
descriptors are stored by user space. For unusable segments,
vmx_segment_access_rights skips all attributes and sets them to 0.

This means we zero out the DPL (Descriptor Privilege Level) for unusable
entries.

Unusable segments are - contrary to their name - usable in 64bit mode and
are used by guests to for example create a linear map through the
NULL selector.

VMENTER checks if SS.DPL is correct depending on the CS segment type.
For types 9 (Execute Only) and 11 (Execute Read), CS.DPL must be equal to
SS.DPL [1].

We have seen real world guests setting CS to a usable segment with DPL=3
and SS to an unusable segment with DPL=3. Once we go through an sregs
get/set cycle, SS.DPL turns to 0. This causes the virtual machine to crash
reproducibly.

This commit changes the attribute logic to always preserve attributes for
unusable segments. According to [2] SS.DPL is always saved on VM exits,
regardless of the unusable bit so user space applications should have saved
the information on serialization correctly.

[3] specifies that besides SS.DPL the rest of the attributes of the
descriptors are undefined after VM entry if unusable bit is set. So, there
should be no harm in setting them all to the previous state.

Commit b2b0a5e978 switched from generic_writepages() to
filemap_fdatawrite_wbc() in gfs2_ail1_start_one() on the path to
replacing ->writepage() with ->writepages() and eventually eliminating
the former.  Function gfs2_ail1_start_one() is called from
gfs2_log_flush(), our main function for flushing the filesystem log.

Unfortunately, at least as implemented today, ->writepage() and
->writepages() are entirely different operations for journaled data
inodes: while the former creates and submits transactions covering the
data to be written, the latter flushes dirty buffers out to disk.

With gfs2_ail1_start_one() now calling ->writepages(), we end up
creating filesystem transactions while we are in the course of a log
flush, which immediately deadlocks on the sdp->sd_log_flush_lock
semaphore.

Work around that by going back to how things used to work before commit
b2b0a5e978 for now; figuring out a superior solution will take time we
don't have available right now.  However ...

Since the removal of generic_writepages() is imminent, open-code it
here.  We're already inside a blk_start_plug() ...  blk_finish_plug()
section here, so skip that part of the original generic_writepages().

This reverts commit b2b0a5e978.

f3bbac3247 ext4: deal with legacy signed xattr name hash values
We potentially have old hashes of the xattr names generated on systems
with signed 'char' types.  Now that everybody uses '-funsigned-char',
those hashes will no longer match.

This only happens if you use xattrs names that have the high bit set,
which probably doesn't happen in practice, but the xfstest generic/454
shows it.

Instead of adding a new "signed xattr hash filesystem" bit and having to
deal with all the possible combinations, just calculate the hash both
ways if the first one fails, and always generate new hashes with the
proper unsigned char version.

ef3691683d KVM: arm64: GICv4.1: Fix race with doorbell on VPE activation/deactivation
To save the vgic LPI pending state with GICv4.1, the VPEs must all be
unmapped from the ITSs so that the sGIC caches can be flushed.
The opposite is done once the state is saved.

This is all done by using the activate/deactivate irqdomain callbacks
directly from the vgic code. Crutially, this is done without holding
the irqdesc lock for the interrupts that represent the VPE. And these
callbacks are changing the state of the irqdesc. What could possibly
go wrong?

If a doorbell fires while we are messing with the irqdesc state,
it will acquire the lock and change the interrupt state concurrently.
Since we don't hole the lock, curruption occurs in on the interrupt
state. Oh well.

While acquiring the lock would fix this (and this was Shanker's
initial approach), this is still a layering violation we could do
without. A better approach is actually to free the VPE interrupt,

It is more work, but this usually happens only once in the lifetime
of the VM and we don't really care about this sort of overhead.

c3b37c2d77 KVM: arm64: Pass the actual page address to mte_clear_page_tags()
Commit d77e59a8fc ("arm64: mte: Lock a page for MTE tag
initialisation") added a call to mte_clear_page_tags() in case a
prior mte_copy_tags_from_user() failed in order to avoid stale tags in
the guest page (it should have really been a separate commit).
Unfortunately, the argument passed to this function was the address of
the struct page rather than the actual page address. Fix this function
call.

71ab9c3e22 net: fix UaF in netns ops registration error path
If net_assign_generic() fails, the current error path in ops_init() tries
to clear the gen pointer slot. Anyway, in such error path, the gen pointer
itself has not been modified yet, and the existing and accessed one is
smaller than the accessed index, causing an out-of-bounds error:

f0950402e8 netlink: prevent potential spectre v1 gadgets
Most netlink attributes are parsed and validated from
__nla_validate_parse() or validate_nla()

    u16 type = nla_type(nla);

    if (type == 0 || type > maxtype) {
        /* error or continue */
    }

@type is then used as an array index and can be used
as a Spectre v1 gadget.

array_index_nospec() can be used to prevent leaking
content of kernel memory to malicious users.

This should take care of vast majority of netlink uses,
but an audit is needed to take care of others where
validation is not yet centralized in core netlink functions.

8caa03f10b io_uring/poll: don't reissue in case of poll race on multishot request
A previous commit fixed a poll race that can occur, but it's only
applicable for multishot requests. For a multishot request, we can safely
ignore a spurious wakeup, as we never leave the waitqueue to begin with.

A blunt reissue of a multishot armed request can cause us to leak a
buffer, if they are ring provided. While this seems like a bug in itself,
it's not really defined behavior to reissue a multishot request directly.
It's less efficient to do so as well, and not required to rearm anything
like it is for singleshot poll requests.

If ksmbd.mountd is configured to assign unknown users to the guest account
("map to guest = bad user" in the config), ksmbd signs the response.

This is wrong according to MS-SMB2 3.3.5.5.3:
   12. If the SMB2_SESSION_FLAG_IS_GUEST bit is not set in the SessionFlags
   field, and Session.IsAnonymous is FALSE, the server MUST sign the

Merge tag 'io_uring-6.2-2023-01-20' of git://git.kernel.dk/linux

Pull io_uring fixes from Jens Axboe:
 "Fixes for the MSG_RING opcode. Nothing really major:

   - Fix an overflow missing serialization around posting CQEs to the
     target ring (me)

   - Disable MSG_RING on a ring that isn't enabled yet. There's nothing
     really wrong with allowing it, but 1) it's somewhat odd as nobody
     can receive them yet, and 2) it means that using the right delivery
     mechanism might change. As nobody should be sending CQEs to a ring
     that isn't enabled yet, let's just disable it (Pavel)

   - Tweak to when we decide to post remotely or not for MSG_RING
     (Pavel)"

1ed46384f8 ARM: SoC DT and driver fixes 6.2
Lots of dts fixes for Qualcomm Snapdragon and NXP i.MX platforms,
 including:
 
  - A regression fix for SDHCI controllers on Inforce 6540, and
    another SDHCI fix on SM8350
 
  - Reenable cluster idle on sm8250 after the the code fix is upstream
 
  - multiple fixes for the QMP PHY binding, needing an incompatible
    dt change
 
  - The reserved memory map is updated on Xiaomi Mi 4C and Huawei Nexus
    6P, to avoid instabilities caused by use of protected memory regions
 
  - Fix i.MX8MP DT for missing GPC Interrupt, power-domain typo and USB
    clock error
 
  - A couple of verdin-imx8mm DT fixes for audio playback support
 
  - Fix pca9547 i2c-mux node name for i.MX and Vybrid device trees
 
  - Fix an imx93-11x11-evk uSDHC pad setting problem that causes Micron
    eMMC CMD8 CRC error in HS400ES/HS400 mode
 
 The remaining ARM and RISC-V platforms only have very few
 smaller dts bugfixes this time:
 
  - A fix for the SiFive unmatched board's PCI memory space
 
  - A revert to fix a regression with GPIO on Marvell Armada
 
  - A fix for the UART address on Marvell AC5
 
  - Missing chip-select phandles for stm32 boards
 
  - Selecting the correct clock for the sam9x60 memory controller
 
  - Amlogic based Odroid-HC4 needs a revert to restore USB
    functionality.
 
 And finally, there are some minor code fixes:
 
  - Build fixes for OMAP1, pxa, riscpc, raspberry pi firmware, and zynq
    firmware
 
  - memory controller driver fixes for an OMAP regression and older bugs
    on tegra, atmel and mvebu
 
  - reset controller fixes for ti-sci and uniphier platforms
 
  - ARM SCMI firmware fixes for a couple of rare corner cases

977c6ba624 EDAC/qcom: Do not pass llcc_driv_data as edac_device_ctl_info's pvt_info
The memory for llcc_driv_data is allocated by the LLCC driver. But when
it is passed as the private driver info to the EDAC core, it will get freed
during the qcom_edac driver release. So when the qcom_edac driver gets probed
again, it will try to use the freed data leading to the use-after-free bug.

Hence, do not pass llcc_driv_data as pvt_info but rather reference it
using the platform_data pointer in the qcom_edac driver.
