commit c422fbd5cb upstream.

The qunipro_g4_sel clear is also needed for new platforms with major

59b12bff04 NFS: Fix READ_PLUS when server doesn't support OP_READ_PLUS
commit f06d1b10cb upstream.

Olga showed me a case where the client was sending multiple READ_PLUS
calls to the server in parallel, and the server replied
NFS4ERR_OPNOTSUPP to each. The client would fall back to READ for the
first reply, but fail to retry the other calls.

I fix this by removing the test for NFS_CAP_READ_PLUS in
nfs4_read_plus_not_supported(). This allows us to reschedule any
READ_PLUS call that has a NFS4ERR_OPNOTSUPP return value, even after the
capability has been cleared.

Shifting *signed int* typed constant 1 left by 31 bits causes undefined

480aba20fa EDAC/igen6: Convert PCIBIOS_* return codes to errnos
commit f8367a74ae upstream.

errcmd_enable_error_reporting() uses pci_{read,write}_config_word()
that return PCIBIOS_* codes. The return code is then returned all the
way into the probe function igen6_probe() that returns it as is. The
probe functions, however, should return normal errnos.

Convert PCIBIOS_* returns code using pcibios_err_to_errno() into normal
errno before returning it from errcmd_enable_error_reporting().

4ead622f74 i3c: master: svc: fix invalidate IBI type and miss call client IBI handler
commit 38baed9b86 upstream.

In an In-Band Interrupt (IBI) handle, the code logic is as follows:

1: writel(SVC_I3C_MCTRL_REQUEST_AUTO_IBI | SVC_I3C_MCTRL_IBIRESP_AUTO,
	  master->regs + SVC_I3C_MCTRL);

2: ret = readl_relaxed_poll_timeout(master->regs + SVC_I3C_MSTATUS, val,
                                    SVC_I3C_MSTATUS_IBIWON(val), 0, 1000);
	...
3: ibitype = SVC_I3C_MSTATUS_IBITYPE(status);
   ibiaddr = SVC_I3C_MSTATUS_IBIADDR(status);

SVC_I3C_MSTATUS_IBIWON may be set before step 1. Thus, step 2 will return
immediately, and the I3C controller has not sent out the 9th SCL yet.
Consequently, ibitype and ibiaddr are 0, resulting in an unknown IBI type
occurrence and missing call I3C client driver's IBI handler.

A typical case is that SVC_I3C_MSTATUS_IBIWON is set when an IBI occurs
during the controller send start frame in svc_i3c_master_xfer().

Clear SVC_I3C_MSTATUS_IBIWON before issue SVC_I3C_MCTRL_REQUEST_AUTO_IBI
to fix this issue.

681ff9a09a ext4: fix mb_cache_entry's e_refcnt leak in ext4_xattr_block_cache_find()

This is because when finding an entry in ext4_xattr_block_cache_find(), if
ext4_sb_bread() returns -ENOMEM, the ce's e_refcnt, which has already grown
in the __entry_find(), won't be put away, and eventually trigger the above
issue in mb_cache_destroy() due to reference count leakage.

So call mb_cache_entry_put() on the -ENOMEM error branch as a quick fix.

eacb8b1955 net: fix __dst_negative_advice() race
commit 92f1655aa2 upstream.

__dst_negative_advice() does not enforce proper RCU rules when
sk->dst_cache must be cleared, leading to possible UAF.

RCU rules are that we must first clear sk->sk_dst_cache,
then call dst_release(old_dst).

Note that sk_dst_reset(sk) is implementing this protocol correctly,
while __dst_negative_advice() uses the wrong order.

Given that ip6_negative_advice() has special logic
against RTF_CACHE, this means each of the three ->negative_advice()
existing methods must perform the sk_dst_reset() themselves.

Note the check against NULL dst is centralized in
__dst_negative_advice(), there is no need to duplicate
it in various callbacks.

Many thanks to Clement Lecigne for tracking this issue.

This old bug became visible after the blamed commit, using UDP sockets.

f76fd94ae6 kdb: Use format-specifiers rather than memset() for padding in kdb_read()
commit c9b51ddb66 upstream.

Currently when the current line should be removed from the display
kdb_read() uses memset() to fill a temporary buffer with spaces.
The problem is not that this could be trivially implemented using a
format string rather than open coding it. The real problem is that
it is possible, on systems with a long kdb_prompt_str, to write past
the end of the tmpbuffer.

Happily, as mentioned above, this can be trivially implemented using a
format string. Make it so!

1c214d3791 kdb: Fix console handling when editing and tab-completing commands
commit db2f9c7dc2 upstream.

Currently, if the cursor position is not at the end of the command buffer
and the user uses the Tab-complete functions, then the console does not
leave the cursor in the correct position.

For example consider the following buffer with the cursor positioned
at the ^:

md kdb_pro 10
          ^

Pressing tab should result in:

md kdb_prompt_str 10
                 ^

However this does not happen. Instead the cursor is placed at the end
(after then 10) and further cursor movement redraws incorrectly. The
same problem exists when we double-Tab but in a different part of the
code.

Fix this by sending a carriage return and then redisplaying the text to
the left of the cursor.

e350d3a6bf kdb: Use format-strings rather than '\0' injection in kdb_read()
commit 09b3598942 upstream.

Currently when kdb_read() needs to reposition the cursor it uses copy and
paste code that works by injecting an '\0' at the cursor position before
delivering a carriage-return and reprinting the line (which stops at the
'\0').

Tidy up the code by hoisting the copy and paste code into an appropriately
named function. Additionally let's replace the '\0' injection with a
proper field width parameter so that the string will be abridged during
formatting instead.

f636a40834 kdb: Fix buffer overflow during tab-complete
commit e9730744bf upstream.

Currently, when the user attempts symbol completion with the Tab key, kdb
will use strncpy() to insert the completed symbol into the command buffer.
Unfortunately it passes the size of the source buffer rather than the
destination to strncpy() with predictably horrible results. Most obviously
if the command buffer is already full but cp, the cursor position, is in
the middle of the buffer, then we will write past the end of the supplied
buffer.

Fix this by replacing the dubious strncpy() calls with memmove()/memcpy()
calls plus explicit boundary checks to make sure we have enough space
before we start moving characters around.

3f531c4cb7 watchdog: rti_wdt: Set min_hw_heartbeat_ms to accommodate a safety margin
commit cae5851653 upstream.

On AM62x, the watchdog is pet before the valid window is open. Fix
min_hw_heartbeat and accommodate a 2% + static offset safety margin.
The static offset accounts for max hardware error.

Remove the hack in the driver which shifts the open window boundary,
since it is no longer necessary due to the fix mentioned above.

40f05fd442 sparc64: Fix number of online CPUs
commit 98937707fe upstream.

Nick Bowler reported:
    When using newer kernels on my Ultra 60 with dual 450MHz UltraSPARC-II
    CPUs, I noticed that only CPU 0 comes up, while older kernels (including
    4.7) are working fine with both CPUs.

      I bisected the failure to this commit:

      9b2f753ec2 is the first bad commit
      commit 9b2f753ec2

      sparc64: Fix cpu_possible_mask if nr_cpus is set

    This is a small change that reverts very easily on top of 5.18: there is
    just one trivial conflict.  Once reverted, both CPUs work again.

    Maybe this is related to the fact that the CPUs on this system are
    numbered CPU0 and CPU2 (there is no CPU1)?

The current code that adjust cpu_possible based on nr_cpu_ids do not
take into account that CPU's may not come one after each other.
Move the chech to the function that setup the cpu_possible mask
so there is no need to adjust it later.

c84978d773 net/ipv6: Fix route deleting failure when metric equals 0
commit bb48727238 upstream.

Problem
=========
After commit 67f6951347 ("ipv6: Move setting default metric for routes"),
we noticed that the logic of assigning the default value of fc_metirc
changed in the ioctl process. That is, when users use ioctl(fd, SIOCADDRT,
rt) with a non-zero metric to add a route,  then they may fail to delete a
route with passing in a metric value of 0 to the kernel by ioctl(fd,
SIOCDELRT, rt). But iproute can succeed in deleting it.

As a reference, when using iproute tools by netlink to delete routes with
a metric parameter equals 0, like the command as follows:

	ip -6 route del fe80::/64 via fe81::5054:ff:fe11:3451 dev eth0 metric 0

the user can still succeed in deleting the route entry with the smallest
metric.

Root Reason
===========
After commit 67f6951347 ("ipv6: Move setting default metric for routes"),
When ioctl() pass in SIOCDELRT with a zero metric, rtmsg_to_fib6_config()
will set a defalut value (1024) to cfg->fc_metric in kernel, and in
ip6_route_del() and the line 4074 at net/ipv3/route.c, it will check by

	if (cfg->fc_metric && cfg->fc_metric != rt->fib6_metric)
		continue;

and the condition is true and skip the later procedure (deleting route)
because cfg->fc_metric != rt->fib6_metric. But before that commit,
cfg->fc_metric is still zero there, so the condition is false and it
will do the following procedure (deleting).

Solution
========
In order to keep a consistent behaviour across netlink() and ioctl(), we
should allow to delete a route with a metric value of 0. So we only do
the default setting of fc_metric in route adding.

commit d3b17c6d9d upstream.

Using completion_done to determine whether the caller has gone
away only works after a complete call.  Furthermore it's still
possible that the caller has not yet called wait_for_completion,
resulting in another potential UAF.

Fix this by making the caller use cancel_work_sync and then freeing
the memory safely.

8287a9d7d4 crypto: ecrdsa - Fix module auto-load on add_key
commit eb5739a1ef upstream.

Add module alias with the algorithm cra_name similar to what we have for
RSA-related and other algorithms.

The kernel attempts to modprobe asymmetric algorithms using the names
"crypto-$cra_name" and "crypto-$cra_name-all." However, since these
aliases are currently missing, the modules are not loaded. For instance,
when using the `add_key` function, the hash algorithm is typically
loaded automatically, but the asymmetric algorithm is not.

1. Cert is generated usings ima-evm-utils test suite with
   `gen-keys.sh`, example cert is provided below:

511ff49371 KVM: arm64: Fix AArch32 register narrowing on userspace write
commit 947051e361 upstream.

When userspace writes to one of the core registers, we make
sure to narrow the corresponding GPRs if PSTATE indicates
an AArch32 context.

The code tries to check whether the context is EL0 or EL1 so
that it narrows the correct registers. But it does so by checking
the full PSTATE instead of PSTATE.M.

As a consequence, and if we are restoring an AArch32 EL0 context
in a 64bit guest, and that PSTATE has *any* bit set outside of
PSTATE.M, we narrow *all* registers instead of only the first 15,
destroying the 64bit state.

Obviously, this is not something the guest is likely to enjoy.

Correctly masking PSTATE to only evaluate PSTATE.M fixes it.

ee89a7d663 mmc: core: Add mmc_gpiod_set_cd_config() function
commit 63a7cd6602 upstream.

Some mmc host drivers may need to fixup a card-detection GPIO's config
to e.g. enable the GPIO controllers builtin pull-up resistor on devices
where the firmware description of the GPIO is broken (e.g. GpioInt with
PullNone instead of PullUp in ACPI DSDT).

Since this is the exception rather then the rule adding a config
parameter to mmc_gpiod_request_cd() seems undesirable, so instead
add a new mmc_gpiod_set_cd_config() function. This is simply a wrapper
to call gpiod_set_config() on the card-detect GPIO acquired through
mmc_gpiod_request_cd().

4b2be0d3e3 media: v4l2-core: hold videodev_lock until dev reg, finishes
commit 1ed4477f2e upstream.

After the new V4L2 device node was registered, some additional
initialization was done before the device node was marked as
'registered'. During the time between creating the device node
and marking it as 'registered' it was possible to open the
device node, which would return -ENODEV since the 'registered'
flag was not yet set.

Hold the videodev_lock mutex from just before the device node
is registered until the 'registered' flag is set. Since v4l2_open
will take the same lock, it will wait until this registration
process is finished. This resolves this race condition.

e8b445e157 media: mxl5xx: Move xpt structures off stack
commit 526f452754 upstream.

When building for LoongArch with clang 18.0.0, the stack usage of
probe() is larger than the allowed 2048 bytes:

  drivers/media/dvb-frontends/mxl5xx.c:1698:12: warning: stack frame size (2368) exceeds limit (2048) in 'probe' [-Wframe-larger-than]
   1698 | static int probe(struct mxl *state, struct mxl5xx_cfg *cfg)
        |            ^
  1 warning generated.

This is the result of the linked LLVM commit, which changes how the
arrays of structures in config_ts() get handled with
CONFIG_INIT_STACK_ZERO and CONFIG_INIT_STACK_PATTERN, which causes the
above warning in combination with inlining, as config_ts() gets inlined
into probe().

This warning can be easily fixed by moving the array of structures off
of the stackvia 'static const', which is a better location for these
variables anyways because they are static data that is only ever read
from, never modified, so allocating the stack space is wasteful.

This drops the stack usage from 2368 bytes to 256 bytes with the same
compiler and configuration.

8149eaddde media: mc: mark the media devnode as registered from the, start
commit 4bc6073615 upstream.

First the media device node was created, and if successful it was
marked as 'registered'. This leaves a small race condition where
an application can open the device node and get an error back
because the 'registered' flag was not yet set.

Change the order: first set the 'registered' flag, then actually
register the media device node. If that fails, then clear the flag.

During boot, Linux kernel complains:

This SoC is using a regular GIC-400 and the GICR space size should be
8KB rather than 256B.

With this patch:

[    0.000000] GIC: Using split EOI/Deactivate mode

Don't subtract 1 from the power index. This was added in commit
2fc0b8e5a1 ("rtl8xxxu: Add TX power base values for gen1 parts")
for unknown reasons. The vendor drivers don't do this.

Also correct the calculations of values written to
REG_OFDM0_X{C,D}_TX_IQ_IMBALANCE. According to the vendor driver,
these are used for TX power training.

With these changes rtl8xxxu sets the TX power of RTL8192CU the same
as the vendor driver.

None of this appears to have any effect on my RTL8192CU device.

098d549348 md/raid5: fix deadlock that raid5d() wait for itself to clear MD_SB_CHANGE_PENDING
commit 151f66bb61 upstream.

Xiao reported that lvm2 test lvconvert-raid-takeover.sh can hang with
small possibility, the root cause is exactly the same as commit
bed9e27baf ("Revert "md/raid5: Wait for MD_SB_CHANGE_PENDING in raid5d"")

However, Dan reported another hang after that, and junxiao investigated
the problem and found out that this is caused by plugged bio can't issue
from raid5d().

Current implementation in raid5d() has a weird dependence:

1) md_check_recovery() from raid5d() must hold 'reconfig_mutex' to clear
   MD_SB_CHANGE_PENDING;
2) raid5d() handles IO in a deadloop, until all IO are issued;
3) IO from raid5d() must wait for MD_SB_CHANGE_PENDING to be cleared;

This behaviour is introduce before v2.6, and for consequence, if other
context hold 'reconfig_mutex', and md_check_recovery() can't update
super_block, then raid5d() will waste one cpu 100% by the deadloop, until
'reconfig_mutex' is released.

Refer to the implementation from raid1 and raid10, fix this problem by
skipping issue IO if MD_SB_CHANGE_PENDING is still set after
md_check_recovery(), daemon thread will be woken up when 'reconfig_mutex'
is released. Meanwhile, the hang problem will be fixed as well.

83c4aba920 soc: qcom: rpmh-rsc: Enhance check for VRM in-flight request
commit f592cc5794 upstream.

Each RPMh VRM accelerator resource has 3 or 4 contiguous 4-byte aligned
addresses associated with it. These control voltage, enable state, mode,
and in legacy targets, voltage headroom. The current in-flight request
checking logic looks for exact address matches. Requests for different
addresses of the same RPMh resource as thus not detected as in-flight.

Add new cmd-db API cmd_db_match_resource_addr() to enhance the in-flight
request check for VRM requests by ignoring the address offset.

This ensures that only one request is allowed to be in-flight for a given
VRM resource. This is needed to avoid scenarios where request commands are
carried out by RPMh hardware out-of-order leading to LDO regulator
over-current protection triggering.
