[ Upstream commit 16b86e5c03c5b3ef35bf5126b35384faa97428f0 ]
Refactor SD MUX driver to be able to reuse the same code on RZ/G3S.
RZ/G2{L,UL} has a limitation with regards to switching the clock source
for SD MUX (MUX clock source has to be switched to 266MHz before
switching b/w 533MHz and 400MHz). Rework the handling of this limitation
to use a clock notifier that is registered according to platform based
initialization data, so the SD MUX code can be reused on RZ/G3S.
As RZ/G2{L,UL} and RZ/G3S use different bits in different registers to
check if the clock switching has been done, this configuration (register
offset, register bits and bitfield width) is now passed through struct
cpg_core_clk::sconf (status configuration) from platform specific
initialization code.
Along with struct cpg_core_clk::sconf the mux table indices are also
passed from platform specific initialization code.
Also, mux flags are now passed to DEF_SD_MUX() as they will be used
later by RZ/G3S.
CPG_WEN_BIT macro has been introduced to select properly the WEN bit
of various registers.

As per the Orin Nano Dev Kit schematic, GPIO_G.02 is not available
on this device family. It should not be used at all on Orin NX/Nano.
Having this unused pin mapped as the suspend key can lead to
unpredictable behavior for low power modes.
Orin NX/Nano uses GPIO_EE.04 as both a "power" button and a "suspend"
button. However, we cannot have two gpio-keys mapped to the same
GPIO. Therefore remove the "suspend" key.

v4l2_subdev_enable/disable_streams_fallback() supports falling back to
.s_stream() for subdevs with a single source pad. It also tracks the
enabled streams for that one pad in the sd->enabled_streams field.
Tracking the enabled streams with sd->enabled_streams does not make
sense, as with .s_stream() there can only be a single stream per pad.
Thus, as the v4l2_subdev_enable/disable_streams_fallback() only supports
a single source pad, all we really need is a boolean which tells whether
streaming has been enabled on this pad or not.
However, as we only need a true/false state for a pad (instead of
tracking which streams have been enabled for a pad), we can easily
extend the fallback mechanism to support multiple source pads as we only
need to keep track of which pads have been enabled.
Change the sd->enabled_streams field to sd->enabled_pads, which is a
64-bit bitmask tracking the enabled source pads. With this change we can
remove the restriction that
v4l2_subdev_enable/disable_streams_fallback() only supports a single
source pad.

v4l2_subdev_enable/disable_streams_fallback(), which was the original

This leads to a conflict as both functions set the field. Afaics, both

The trace event verifier checks the formats of trace events to make sure
that they do not point at memory that is not in the trace event itself or
in data that will never be freed. If an event references data that was
allocated when the event triggered and that same data is freed before the
event is read, then the kernel can crash by reading freed memory.
The verifier runs at boot up (or module load) and scans the print formats
of the events and checks their arguments to make sure that dereferenced
pointers are safe. If the format uses "%*p.." the verifier will ignore it,
and that could be dangerous. Cover this case as well.
Also add to the sample code a use case of "%*pbl".

Patch series "mm/hwpoison: Fix regressions in memory failure handling",
v4.
## 1. What am I trying to do:
This patchset resolves two critical regressions related to memory failure
handling that have appeared in the upstream kernel since version 5.17, as
compared to 5.10 LTS.
- copyin case: poison found in user page while kernel copying from user space
- instr case: poison found while instruction fetching in user space
## 2. What is the expected outcome and why
- For copyin case:
Kernel can recover from poison found where kernel is doing get_user() or
copy_from_user() if those places get an error return and the kernel return
-EFAULT to the process instead of crashing. More specifily, MCE handler
checks the fixup handler type to decide whether an in kernel #MC can be
recovered. When EX_TYPE_UACCESS is found, the PC jumps to recovery code
specified in _ASM_EXTABLE_FAULT() and return a -EFAULT to user space.
- For instr case:
If a poison found while instruction fetching in user space, full recovery
is possible. User process takes #PF, Linux allocates a new page and fills
by reading from storage.
## 3. What actually happens and why
- For copyin case: kernel panic since v5.17
Commit 4c132d1d84 ("x86/futex: Remove .fixup usage") introduced a new
extable fixup type, EX_TYPE_EFAULT_REG, and later patches updated the
extable fixup type for copy-from-user operations, changing it from
EX_TYPE_UACCESS to EX_TYPE_EFAULT_REG. It breaks previous EX_TYPE_UACCESS
handling when posion found in get_user() or copy_from_user().
- For instr case: user process is killed by a SIGBUS signal due to #CMCI
and #MCE race
When an uncorrected memory error is consumed there is a race between the
CMCI from the memory controller reporting an uncorrected error with a UCNA
signature, and the core reporting and SRAR signature machine check when
the data is about to be consumed.
### Background: why *UN*corrected errors tied to *C*MCI in Intel platform [1]
Prior to Icelake memory controllers reported patrol scrub events that
detected a previously unseen uncorrected error in memory by signaling a
broadcast machine check with an SRAO (Software Recoverable Action
Optional) signature in the machine check bank. This was overkill because
it's not an urgent problem that no core is on the verge of consuming that
bad data. It's also found that multi SRAO UCE may cause nested MCE
interrupts and finally become an IERR.
Hence, Intel downgrades the machine check bank signature of patrol scrub
from SRAO to UCNA (Uncorrected, No Action required), and signal changed to
#CMCI. Just to add to the confusion, Linux does take an action (in
uc_decode_notifier()) to try to offline the page despite the UC*NA*
signature name.
### Background: why #CMCI and #MCE race when poison is consuming in
Intel platform [1]
Having decided that CMCI/UCNA is the best action for patrol scrub errors,
the memory controller uses it for reads too. But the memory controller is
executing asynchronously from the core, and can't tell the difference
between a "real" read and a speculative read. So it will do CMCI/UCNA if
an error is found in any read.
Thus:
1) Core is clever and thinks address A is needed soon, issues a
speculative read.
2) Core finds it is going to use address A soon after sending the read
request
3) The CMCI from the memory controller is in a race with MCE from the
core that will soon try to retire the load from address A.
Quite often (because speculation has got better) the CMCI from the memory
controller is delivered before the core is committed to the instruction
reading address A, so the interrupt is taken, and Linux offlines the page
(marking it as poison).
## Why user process is killed for instr case
Commit 046545a661 ("mm/hwpoison: fix error page recovered but reported
"not recovered"") tries to fix noise message "Memory error not recovered"
and skips duplicate SIGBUSs due to the race. But it also introduced a bug
that kill_accessing_process() return -EHWPOISON for instr case, as result,
kill_me_maybe() send a SIGBUS to user process.
# 4. The fix, in my opinion, should be:
- For copyin case:
The key point is whether the error context is in a read from user memory.
We do not care about the ex-type if we know its a MOV reading from
userspace.
is_copy_from_user() return true when both of the following two checks are
true:
- the current instruction is copy
- source address is user memory
If copy_user is true, we set
m->kflags |= MCE_IN_KERNEL_COPYIN | MCE_IN_KERNEL_RECOV;
Then do_machine_check() will try fixup_exception() first.
- For instr case: let kill_accessing_process() return 0 to prevent a SIGBUS.
- For patch 3:
The return value of memory_failure() is quite important while discussed
instr case regression with Tony and Miaohe for patch 2, so add comment
about the return value.
This patch (of 3):
Commit 4c132d1d84 ("x86/futex: Remove .fixup usage") introduced a new
extable fixup type, EX_TYPE_EFAULT_REG, and commit 4c132d1d84
("x86/futex: Remove .fixup usage") updated the extable fixup type for
copy-from-user operations, changing it from EX_TYPE_UACCESS to
EX_TYPE_EFAULT_REG. The error context for copy-from-user operations no
longer functions as an in-kernel recovery context. Consequently, the
error context for copy-from-user operations no longer functions as an
in-kernel recovery context, resulting in kernel panics with the message:
"Machine check: Data load in unrecoverable area of kernel."
To address this, it is crucial to identify if an error context involves a
read operation from user memory. The function is_copy_from_user() can be
utilized to determine:
- the current operation is copy
- when reading user memory
When these conditions are met, is_copy_from_user() will return true,
confirming that it is indeed a direct copy from user memory. This check
is essential for correctly handling the context of errors in these
operations without relying on the extable fixup types that previously
allowed for in-kernel recovery.
So, use is_copy_from_user() to determine if a context is copy user directly.

Switch away from using sha1 for module signing by default and use the
more modern sha512 instead, which is what among others Arch, Fedora,
RHEL, and Ubuntu are currently using for their kernels.
Sha1 has not been considered secure against well-funded opponents since
2005[1]; since 2011 the NIST and other organizations furthermore
recommended its replacement[2]. This is why OpenSSL on RHEL9, Fedora
Linux 41+[3], and likely some other current and future distributions
reject the creation of sha1 signatures, which leads to a build error of
allmodconfig configurations:
80A20474797F0000:error:03000098:digital envelope routines:do_sigver_init:invalid digest:crypto/evp/m_sigver.c:342:

This change makes allmodconfig work again and sets a default that is
more appropriate for current and future users, too.

The dealloc flag may be cleared and the extent won't reach the disk in
cow_file_range when errors path. The reserved qgroup space is freed in
commit 30479f31d44d ("btrfs: fix qgroup reserve leaks in
cow_file_range"). However, the length of untouched region to free needs
to be adjusted with the correct remaining region size.

Ricardo reported a KASAN discovered use after free in v6.6-stable.
The syzbot starts a BPF program via xdp_test_run_batch() which assigns
ri->tgt_value via dev_hash_map_redirect() and the return code isn't
XDP_REDIRECT it looks like nonsense. So the output in
bpf_warn_invalid_xdp_action() appears once.
Then the TUN driver runs another BPF program (on the same CPU) which
returns XDP_REDIRECT without setting ri->tgt_value first. It invokes
bpf_trace_printk() to print four characters and obtain the required
return value. This is enough to get xdp_do_redirect() invoked which
then accesses the pointer in tgt_value which might have been already
deallocated.
This problem does not affect upstream because since commit
401cb7dae8130 ("net: Reference bpf_redirect_info via task_struct on PREEMPT_RT.")
the per-CPU variable is referenced via task's task_struct and exists on
the stack during NAPI callback. Therefore it is cleared once before the
first invocation and remains valid within the RCU section of the NAPI
callback.
Instead of performing the huge backport of the commit (plus its fix ups)
here is an alternative version which only resets the variable in
question prior invoking the BPF program.

commit 15383a0d63dbcd63dc7e8d9ec1bf3a0f7ebf64ac upstream.
Some fixes may require user space to check if they are applied on the
running kernel before using a specific feature. For instance, this
applies when a restriction was previously too restrictive and is now
getting relaxed (e.g. for compatibility reasons). However, non-visible
changes for legitimate use (e.g. security fixes) do not require an
erratum.
Because fixes are backported down to a specific Landlock ABI, we need a
way to avoid cherry-pick conflicts. The solution is to only update a
file related to the lower ABI impacted by this issue. All the ABI files
are then used to create a bitmask of fixes.
The new errata interface is similar to the one used to get the supported
Landlock ABI version, but it returns a bitmask instead because the order
of fixes may not match the order of versions, and not all fixes may
apply to all versions.
The actual errata will come with dedicated commits. The description is
not actually used in the code but serves as documentation.
Create the landlock_abi_version symbol and use its value to check errata
consistency.
Update test_base's create_ruleset_checks_ordering tests and add errata
tests.
This commit is backportable down to the first version of Landlock.

commit 30479f31d44d47ed00ae0c7453d9b253537005b2 upstream.
In the buffered write path, the dirty page owns the qgroup reserve until
it creates an ordered_extent.
Therefore, any errors that occur before the ordered_extent is created
must free that reservation, or else the space is leaked. The fstest
generic/475 exercises various IO error paths, and is able to trigger
errors in cow_file_range where we fail to get to allocating the ordered
extent. Note that because we *do* clear delalloc, we are likely to
remove the inode from the delalloc list, so the inodes/pages to not have
invalidate/launder called on them in the commit abort path.
This results in failures at the unmount stage of the test that look like:
BTRFS: error (device dm-8 state EA) in cleanup_transaction:2018: errno=-5 IO failure
BTRFS: error (device dm-8 state EA) in btrfs_replace_file_extents:2416: errno=-5 IO failure
