EFI fixes for v6.8 #1
- Tighten ELF relocation checks on the RISC-V EFI stub
- Give up if the new EFI memory attributes protocol fails spuriously on
x86
- Take care not to place the kernel in the lowest 16 MB of DRAM on x86
- Omit special purpose EFI memory from memblock
- Some fixes for the CXL CPER reporting code
- Make the PE/COFF layout of mixed-mode capable images comply with a
strict interpretation of the spec

Pull EFI fixes from Ard Biesheuvel:
"The only notable change here is the patch that changes the way we deal
with spurious errors from the EFI memory attribute protocol. This will
be backported to v6.6, and is intended to ensure that we will not
paint ourselves into a corner when we tighten this further in order to
comply with MS requirements on signed EFI code.
Note that this protocol does not currently exist in x86 production
systems in the field, only in Microsoft's fork of OVMF, but it will be
mandatory for Windows logo certification for x86 PCs in the future.

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) Narrow down target/match revision to u8 in nft_compat.
2) Bail out with unused flags in nft_compat.
3) Restrict layer 4 protocol to u16 in nft_compat.
4) Remove static in pipapo get command that slipped through when
reducing set memory footprint.
5) Follow up incremental fix for the ipset performance regression,
this includes the missing gc cancellation, from Jozsef Kadlecsik.
6) Allow to filter by zone 0 in ctnetlink, do not interpret zone 0
as no filtering, from Felix Huettner.
7) Reject direction for NFT_CT_ID.
8) Use timestamp to check for set element expiration while transaction
is handled to prevent garbage collection from removing set elements
that were just added by this transaction. Packet path and netlink
dump/get path still use current time to check for expiration.
9) Restore NF_REPEAT in nfnetlink_queue, from Florian Westphal.
10) map_index needs to be percpu and per-set, not just percpu.
At this time its possible for a pipapo set to fill the all-zero part
with ones and take the 'might have bits set' as 'start-from-zero' area.
From Florian Westphal. This includes three patches:
- Change scratchpad area to a structure that provides space for a
per-set-and-cpu toggle and uses it of the percpu one.
- Add a new free helper to prepare for the next patch.
- Remove the scratch_aligned pointer and makes AVX2 implementation
use the exact same memory addresses for read/store of the matching
state.

netfilter: nf_tables: use timestamp to check for set element timeout
Add a timestamp field at the beginning of the transaction, store it
in the nftables per-netns area.
Update set backend .insert, .deactivate and sync gc path to use the
timestamp, this avoids that an element expires while control plane
transaction is still unfinished.
.lookup and .update, which are used from packet path, still use the
current time to check if the element has expired. And .get path and dump
also since this runs lockless under rcu read size lock. Then, there is
async gc which also needs to check the current time since it runs
asynchronously from a workqueue.

libceph: just wait for more data to be available on the socket
A short read may occur while reading the message footer from the
socket. Later, when the socket is ready for another read, the
messenger invokes all read_partial_*() handlers, including
read_partial_sparse_msg_data(). The expectation is that
read_partial_sparse_msg_data() would bail, allowing the messenger to
invoke read_partial() for the footer and pick up where it left off.
However read_partial_sparse_msg_data() violates that and ends up
calling into the state machine in the OSD client. The sparse-read
state machine assumes that it's a new op and interprets some piece of
the footer as the sparse-read header and returns bogus extents/data
length, etc.
To determine whether read_partial_sparse_msg_data() should bail, let's
reuse cursor->total_resid. Because once it reaches to zero that means
all the extents and data have been successfully received in last read,
else it could break out when partially reading any of the extents and
data. And then osd_sparse_read() could continue where it left off.

blk-wbt: Fix detection of dirty-throttled tasks
The detection of dirty-throttled tasks in blk-wbt has been subtly broken
since its beginning in 2016. Namely if we are doing cgroup writeback and
the throttled task is not in the root cgroup, balance_dirty_pages() will
set dirty_sleep for the non-root bdi_writeback structure. However
blk-wbt checks dirty_sleep only in the root cgroup bdi_writeback
structure. Thus detection of recently throttled tasks is not working in
this case (we noticed this when we switched to cgroup v2 and suddently
writeback was slow).
Since blk-wbt has no easy way to get to proper bdi_writeback and
furthermore its intention has always been to work on the whole device
rather than on individual cgroups, just move the dirty_sleep timestamp
from bdi_writeback to backing_dev_info. That fixes the checking for
recently throttled task and saves memory for everybody as a bonus.

hrtimer: Report offline hrtimer enqueue
The hrtimers migration on CPU-down hotplug process has been moved
earlier, before the CPU actually goes to die. This leaves a small window
of opportunity to queue an hrtimer in a blind spot, leaving it ignored.
For example a practical case has been reported with RCU waking up a
SCHED_FIFO task right before the CPUHP_AP_IDLE_DEAD stage, queuing that
way a sched/rt timer to the local offline CPU.
Make sure such situations never go unnoticed and warn when that happens.

rxrpc: Fix counting of new acks and nacks
Fix the counting of new acks and nacks when parsing a packet - something
that is used in congestion control.
As the code stands, it merely notes if there are any nacks whereas what we
really should do is compare the previous SACK table to the new one,
assuming we get two successive ACK packets with nacks in them. However, we
really don't want to do that if we can avoid it as the tables might not
correspond directly as one may be shifted from the other - something that
will only get harder to deal with once extended ACK tables come into full
use (with a capacity of up to 8192).
Instead, count the number of nacks shifted out of the old SACK, the number
of nacks retained in the portion still active and the number of new acks
and nacks in the new table then calculate what we need.
Note this ends up a bit of an estimate as the Rx protocol allows acks to be
withdrawn by the receiver and packets requested to be retransmitted.

...
CXL events were rerouted though the CXL subsystem for additional
processing. However, when that work was done it was missed that
cper_estatus_print_section() continued with a generic error message
which is confusing.
Teach CPER print code to ignore printing details of some section types.
Assign the CXL event GUIDs to this set to prevent confusing unknown
prints.

ASoC: cs35l56: Load tunings for the correct speaker models
If the "spk-id-gpios" property is present it points to GPIOs whose
value must be used to select the correct bin file to match the
speakers.
Some manufacturers use multiple sources of speakers, which need
different tunings for best performance. On these models the type of
speaker fitted is indicated by the values of one or more GPIOs. The
number formed by the GPIOs identifies the tuning required.
The speaker ID must be used in combination with the subsystem ID
(either from PCI SSID or cirrus,firmware-uid property), because the
GPIOs can only indicate variants of a specific model.

ASoC: cs35l56: Firmware file must match the version of preloaded firmware
Check during initialization whether the firmware is already patched.
If so, include the firmware version in the wm_adsp fwf_name string.
If the firmware has already been patched by the BIOS the driver
can only replace it if it has control of hard RESET.
If the driver cannot replace the firmware, it can still load a wmfw
(for ALSA control definitions) and/or a bin (for additional tunings).
But these must match the version of firmware that is running on the
CS35L56.
The firmware is pre-patched if FIRMWARE_MISSING == 0.
Including the firmware version in the fwf_name string will
qualify the firmware file name:
Normal (unpatched or replaceable firmware):
cs35l56-rev-dsp1-misc[-system_name].[wmfw|bin]
Preloaded firmware:
cs35l56-rev[-s]-VVVVVV-dsp1-misc[-system_name].[wmfw|bin]
Where:
[-s] is an optional -s added into the name for a secured CS35L56
VVVVVV is the 24-bit firmware version in hexadecimal.

ASoC: cs35l56: Fix to ensure ASP1 registers match cache
Add a dummy SUPPLY widget connected to the ASP that forces the
chip registers to match the regmap cache when the ASP is
powered-up.
On a SoundWire system the ASP is free for use as a chip-to-chip
interconnect. This can be either for the firmware on multiple
CS35L56 to share reference audio; or as a bridge to another
device. If it is a firmware interconnect it is owned by the
firmware and the Linux driver should avoid writing the registers.
However. If it is a bridge then Linux may take over and handle
it as a normal codec-to-codec link.
CS35L56 is designed for SDCA and a generic SDCA driver would
know nothing about these chip-specific registers. So if the
ASP is being used on a SoundWire system the firmware sets up the
ASP registers. This means that we can't assume the default
state of the ASP registers. But we don't know the initial state
that the firmware set them to until after the firmware has been
downloaded and booted, which can take several seconds when
downloading multiple amps.
To avoid blocking probe() for several seconds waiting for the
firmware, the silicon defaults are assumed. This allows the machine
driver to setup the ASP configuration during probe() without being
blocked. If the ASP is hooked up and used, the SUPPLY widget
ensures that the chip registers match what was configured in the
regmap cache.
If the machine driver does not hook up the ASP, it is assumed that
it won't call any functions to configure the ASP DAI. Therefore
the regmap cache will be clean for these registers so a
regcache_sync() will not overwrite the chip registers. If the
DAI is not hooked up, the dummy SUPPLY widget will not be
invoked so it will never force-overwrite the chip registers.
Backport note:
This won't apply cleanly to kernels older than v6.6.

af_unix: fix lockdep positive in sk_diag_dump_icons()
syzbot reported a lockdep splat [1].
Blamed commit hinted about the possible lockdep
violation, and code used unix_state_lock_nested()
in an attempt to silence lockdep.
It is not sufficient, because unix_state_lock_nested()
is already used from unix_state_double_lock().
We need to use a separate subclass.
This patch adds a distinct enumeration to make things
more explicit.
Also use swap() in unix_state_double_lock() as a clean up.
v2: add a missing inline keyword to unix_state_lock_nested()

nvme: take const cmd pointer in read-only helpers
nvme_is_fabrics() and nvme_is_write() only read struct nvme_command, so take it by const pointer. This allows callers to pass a const pointer and communicates that these functions don't modify the command.

PCI/ASPM: Fix deadlock when enabling ASPM
A last minute revert in 6.7-final introduced a potential deadlock when
enabling ASPM during probe of Qualcomm PCIe controllers as reported by

The deadlock can easily be reproduced on machines like the Lenovo ThinkPad
X13s by adding a delay to increase the race window during asynchronous
probe where another thread can take a write lock.
Add a new pci_set_power_state_locked() and associated helper functions that
can be called with the PCI bus semaphore held to avoid taking the read lock
twice.

HID: bpf: use __bpf_kfunc instead of noinline
Follow the docs at Documentation/bpf/kfuncs.rst: - declare the function with `__bpf_kfunc` - disables missing prototype warnings, which allows to remove them from include/linux/hid-bpf.h Removing the prototypes is not an issue because we currently have to redeclare them when writing the BPF program. They will eventually be generated by bpftool directly AFAIU.

lsm: fix default return value of the socket_getpeersec_*() hooks
For these hooks the true "neutral" value is -EOPNOTSUPP, which is
currently what is returned when no LSM provides this hook and what LSMs
return when there is no security context set on the socket. Correct the
value in <linux/lsm_hooks.h> and adjust the dispatch functions in
security/security.c to avoid issues when the BPF LSM is enabled.

dst is set.
After the below commit, the skb dst is dropped by ipv4_pktinfo_prepare(),

ata changes for 6.8-rc2
- Fix an incorrect link_power_management_policy sysfs attribute
value. We were previously using the same attribute value for
two different LPM policies (me).
- Add a ASMedia ASM1166 quirk. The SATA host controller always
reports that it has 32 ports, even though it only has six ports.
Add a quirk that overrides the value reported by the controller
(Conrad).
- Add a ASMedia ASM1061 quirk. The SATA host controller completely
ignores the upper 21 bits of the DMA address. This causes IOMMU
error events when a (valid) DMA address actually has any of the
upper 21 bits set. Add a quirk that limits the dma_mask to
43-bits (Lennert).

Pull ata updates from Niklas Cassel:
- Fix an incorrect link_power_management_policy sysfs attribute value.
We were previously using the same attribute value for two different
LPM policies (me)
- Add a ASMedia ASM1166 quirk.
The SATA host controller always reports that it has 32 ports, even
though it only has six ports. Add a quirk that overrides the value
reported by the controller (Conrad)
- Add a ASMedia ASM1061 quirk.
The SATA host controller completely ignores the upper 21 bits of the
DMA address. This causes IOMMU error events when a (valid) DMA
address actually has any of the upper 21 bits set. Add a quirk that
limits the dma_mask to 43-bits (Lennert)
* tag 'ata-6.8-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/libata/linux:

spi: Fixes for v6.8
As well as a few device IDs and the usual scattering of driver specific fixes this contains a couple of core things. One is a missed case in error handling, the other patch is a change from me raising the number of chip selects allowed by the newly added multi chip select support patches to resolve problems seen on several systems that exceeded the limit. This is not a real solution to the issue but rather just a change to avoid disruption to users, one of the options I am considering is just sending a revert of those changes if we can't come up with something sensible. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmWz7e0ACgkQJNaLcl1U h9BOrAf/UwWplCW+rCznfkb8uAuShKlJux+RtAJZG8A70JeC3jsdN66yUyxmfrIY 5qKtqcPA3VXdM8OQ/3r8tk/q+/2sXESLotefwKvONYrZYmq61lA+rayUiNDQjicJ devvPLns72ZKu3VpsdFAoXzA+mL8Byp65lBqW5dHVyt0itY1Ap2Zdi8CNSzEVLLs 3Qhe26yy8sxILQZ6N4TSNYMV7l6yn3AjZ5kUDFi/CA1AWTTfazpioCAyADa3iTpR 1i0zsMzeDEL0iu8gWuB62mqftwY5ua3NaSmpxWPebG4VtMXqu62PwQugiqmq+gDc bA0SLlzR4xub7dtyhEjmsCbn4pvafw== =RQ5N -----END PGP SIGNATURE----- Merge tag 'spi-fix-v6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi Pull spi fixes from Mark Brown: "As well as a few device IDs and the usual scattering of driver specific fixes this contains a couple of core things.

mm, kmsan: fix infinite recursion due to RCU critical section
Alexander Potapenko writes in [1]: "For every memory access in the code
instrumented by KMSAN we call kmsan_get_metadata() to obtain the metadata
for the memory being accessed. For virtual memory the metadata pointers
are stored in the corresponding `struct page`, therefore we need to call
virt_to_page() to get them.
According to the comment in arch/x86/include/asm/page.h,
virt_to_page(kaddr) returns a valid pointer iff virt_addr_valid(kaddr) is
true, so KMSAN needs to call virt_addr_valid() as well.
To avoid recursion, kmsan_get_metadata() must not call instrumented code,
therefore ./arch/x86/include/asm/kmsan.h forks parts of
arch/x86/mm/physaddr.c to check whether a virtual address is valid or not.
But the introduction of rcu_read_lock() to pfn_valid() added instrumented
RCU API calls to virt_to_page_or_null(), which is called by
kmsan_get_metadata(), so there is an infinite recursion now. I do not
think it is correct to stop that recursion by doing
kmsan_enter_runtime()/kmsan_exit_runtime() in kmsan_get_metadata(): that
would prevent instrumented functions called from within the runtime from
tracking the shadow values, which might introduce false positives."
Fix the issue by switching pfn_valid() to the _sched() variant of
rcu_read_lock/unlock(), which does not require calling into RCU. Given
the critical section in pfn_valid() is very small, this is a reasonable
trade-off (with preemptible RCU).
KMSAN further needs to be careful to suppress calls into the scheduler,
which would be another source of recursion. This can be done by wrapping
the call to pfn_valid() into preempt_disable/enable_no_resched(). The
downside is that this sacrifices breaking scheduling guarantees; however,
a kernel compiled with KMSAN has already given up any performance
guarantees due to being heavily instrumented.
Note, KMSAN code already disables tracing via Makefile, and since mmzone.h
is included, it is not necessary to use the notrace variant, which is
generally preferred in all other cases.
