commit fb99ef17865035a6657786d4b2af11a27ba23f9b upstream.
There is no direct device ancestry defined between an ata_device and
its scsi device which prevents the power management code from correctly
ordering suspend and resume operations. Create such ancestry with the
ata device as the parent to ensure that the scsi device (child) is
suspended before the ata device and that resume handles the ata device
before the scsi device.
The parent-child (supplier-consumer) relationship is established between
the ata_port (parent) and the scsi device (child) with the function
device_add_link(). The parent used is not the ata_device as the PM
operations are defined per port and the status of all devices connected
through that port is controlled from the port operations.
The device link is established with the new function
ata_scsi_slave_alloc(), and this function is used to define the
->slave_alloc callback of the scsi host template of all ata drivers.

commit 1943feecf80e73ecc03ce40271f29c6cea142bac upstream.
For 64bit kernel without HIGHMEM, high_memory is the virtual address of
the highest physical address in the system. But __va(get_num_physpages()
<< PAGE_SHIFT) is not what we want for high_memory because there may be
holes in the physical address space. On the other hand, max_low_pfn is
calculated from memblock_end_of_DRAM(), which is exactly corresponding
to the highest physical address, so use it for high_memory calculation.

[ Upstream commit f15f29fd4779be8a418b66e9d52979bb6d6c2325 ]
Chain binding only requires the rule addition/insertion command within
the same transaction. Removal of rules from chain bindings within the
same transaction makes no sense, userspace does not utilize this
feature. Replace nft_chain_is_bound() check to nft_chain_binding() in
rule deletion commands. Replace command implies a rule deletion, reject
this command too.
Rule flush command can also safely rely on this nft_chain_binding()
check because unbound chains are not allowed since 62e1e94b246e
("netfilter: nf_tables: reject unbound chain set before commit phase").

commit 7ee29facd8a9c5a26079148e36bcf07141b3a6bc upstream.
In nilfs_gccache_submit_read_data(), brelse(bh) is called to drop the
reference count of bh when the call to nilfs_dat_translate() fails. If
the reference count hits 0 and its owner page gets unlocked, bh may be
freed. However, bh->b_page is dereferenced to put the page after that,
which may result in a use-after-free bug. This patch moves the release
operation after unlocking and putting the page.
NOTE: The function in question is only called in GC, and in combination
with current userland tools, address translation using DAT does not occur
in that function, so the code path that causes this issue will not be
executed. However, it is possible to run that code path by intentionally
modifying the userland GC library or by calling the GC ioctl directly.

commit cce7fc8b29961b64fadb1ce398dc5ff32a79643b upstream.
In case the leaf driver wants to use IRQ polling (irq = 0) and
IIR register shows that an interrupt happened in the 8250 hardware
the IRQ data can be NULL. In such a case we need to skip the wake
event as we came to this path from the timer interrupt and quite
likely system is already awake.
Without this fix we have got an Oops:

commit 29346e217b8ab8a52889b88f00b268278d6b7668 upstream.
This reverts commit 9b9c8195f3f0d74a826077fc1c01b9ee74907239.
The commit above is reverted as it did not solve the original issue.
gsm_cleanup_mux() tries to free up the virtual ttys by calling
gsm_dlci_release() for each available DLCI. There, dlci_put() is called to
decrease the reference counter for the DLCI via tty_port_put() which
finally calls gsm_dlci_free(). This already clears the pointer which is
being checked in gsm_cleanup_mux() before calling gsm_dlci_release().
Therefore, it is not necessary to clear this pointer in gsm_cleanup_mux()
as done in the reverted commit. The commit introduces a null pointer
dereference:

commit 6bec041147a2a64a490d1f813e8a004443061b38 upstream.
In case multiple subflows race to update the mptcp-level receive
window, the subflow losing the race should use the window value
provided by the "winning" subflow to update it's own tcp-level
rcv_wnd.
To such goal, the current code bogusly uses the mptcp-level rcv_wnd
value as observed before the update attempt. On unlucky circumstances
that may lead to TCP-level window shrinkage, and stall the other end.
Address the issue feeding to the rcv wnd update the correct value.

commit 50107e8b2a8a59d8cec7e8454e27c1f8e365acdb upstream.
The mmu_notifier path is a bit of a special snowflake, e.g. it zaps only a
single address space (because it's per-slot), and can't always yield.
Because of this, it calls kvm_tdp_mmu_zap_leafs() in ways that no one
else does.
Iterate manually over the leafs in response to an mmu_notifier
invalidation, instead of invoking kvm_tdp_mmu_zap_leafs(). Drop the
@can_yield param from kvm_tdp_mmu_zap_leafs() as its sole remaining
caller unconditionally passes "true".

commit e0096d01c4fcb8c96c05643cfc2c20ab78eae4da upstream.
The checks for virtualizing TSC_AUX occur during the vCPU reset processing
path. However, at the time of initial vCPU reset processing, when the vCPU
is first created, not all of the guest CPUID information has been set. In
this case the RDTSCP and RDPID feature support for the guest is not in
place and so TSC_AUX virtualization is not established.
This continues for each vCPU created for the guest. On the first boot of
an AP, vCPU reset processing is executed as a result of an APIC INIT
event, this time with all of the guest CPUID information set, resulting
in TSC_AUX virtualization being enabled, but only for the APs. The BSP
always sees a TSC_AUX value of 0 which probably went unnoticed because,
at least for Linux, the BSP TSC_AUX value is 0.
Move the TSC_AUX virtualization enablement out of the init_vmcb() path and
into the vcpu_after_set_cpuid() path to allow for proper initialization of
the support after the guest CPUID information has been set.
With the TSC_AUX virtualization support now in the vcpu_set_after_cpuid()
path, the intercepts must be either cleared or set based on the guest
CPUID input.

commit c6c2adcba50c2622ed25ba5d5e7f05f584711358 upstream.
The SGX EPC reclaimer (ksgxd) may reclaim the SECS EPC page for an
enclave and set secs.epc_page to NULL. The SECS page is used for EAUG
and ELDU in the SGX page fault handler. However, the NULL check for
secs.epc_page is only done for ELDU, not EAUG before being used.
Fix this by doing the same NULL check and reloading of the SECS page as
needed for both EAUG and ELDU.
The SECS page holds global enclave metadata. It can only be reclaimed
when there are no other enclave pages remaining. At that point,
virtually nothing can be done with the enclave until the SECS page is
paged back in.
An enclave can not run nor generate page faults without a resident SECS
page. But it is still possible for a #PF for a non-SECS page to race
with paging out the SECS page: when the last resident non-SECS page A
triggers a #PF in a non-resident page B, and then page A and the SECS
both are paged out before the #PF on B is handled.
Hitting this bug requires that race triggered with a #PF for EAUG.
Following is a trace when it happens.

The commit 06ff87bae8d3 ("arm64: mm: remove unused functions and variable
protoypes") fixed a similar lockup on the CPU MMU side. Yet, it can occur
to SMMU too since arm_smmu_mm_invalidate_range() is typically called next
to MMU tlb flush function, e.g.
tlb_flush_mmu_tlbonly {
tlb_flush {
__flush_tlb_range {
// check MAX_TLBI_OPS
}
}
mmu_notifier_invalidate_range {
arm_smmu_mm_invalidate_range {
// does not check MAX_TLBI_OPS
}
}
}
Clone a CMDQ_MAX_TLBI_OPS from the MAX_TLBI_OPS in tlbflush.h, since in an
SVA case SMMU uses the CPU page table, so it makes sense to align with the
tlbflush code. Then, replace per-page TLBI commands with a single per-asid
TLBI command, if the request size hits this threshold.

[ Upstream commit 2c085f3a8f23c9b444e8b99d93c15d7ce870fc4e ]
smack_dentry_create_files_as() determines whether transmuting should occur
based on the label of the parent directory the new inode will be added to,
and not the label of the directory where it is created.
This helps for example to do transmuting on overlayfs, since the latter
first creates the inode in the working directory, and then moves it to the
correct destination.
However, despite smack_dentry_create_files_as() provides the correct label,
smack_inode_init_security() does not know from passed information whether
or not transmuting occurred. Without this information,
smack_inode_init_security() cannot set SMK_INODE_CHANGED in smk_flags,
which will result in the SMACK64TRANSMUTE xattr not being set in

Thus, add the smk_transmuted field to the task_smack structure, and set it
in smack_dentry_create_files_as() to smk_task if transmuting occurred. If
smk_task is equal to smk_transmuted in smack_inode_init_security(), act as
if transmuting was successful but without taking the label from the parent
directory (the inode label was already set correctly from the current
credentials in smack_inode_alloc_security()).

[ Upstream commit d54820b22e404b06b2b65877ff802cc7b31688bc ]
When target mode is enabled, the pci_irq_get_affinity() function may return
a NULL value in qla_mapq_init_qp_cpu_map() due to the qla24xx_enable_msix()
code that handles IRQ settings for target mode. This leads to a crash due
to a NULL pointer dereference.
This patch fixes the issue by adding a check for the NULL value returned by
pci_irq_get_affinity() and introducing a 'cpu_mapped' boolean flag to the
qla_qpair structure, ensuring that the qpair's CPU affinity is updated when
it has not been mapped to a CPU.

[ Upstream commit 400ece6c7f346b0a30867bd00b03b5b2563d4357 ]
When a station idles for a long time, hostapd will try to send a QoS Null
frame to the station as "poll". NL80211_CMD_PROBE_CLIENT is used for this
purpose. And the skb will be added to ack_status_frame - waiting for a
completion via ieee80211_report_ack_skb().
But when the peer was already removed before the tx_complete arrives, the
peer will be missing. And when using dev_kfree_skb_any (instead of going
through mac80211), the entry will stay inside ack_status_frames. This IDR
will therefore run full after 8K request were generated for such clients.
At this point, the access point will then just stall and not allow any new
clients because idr_alloc() for ack_status_frame will fail.
ieee80211_free_txskb() on the other hand will (when required) call
ieee80211_report_ack_skb() and make sure that (when required) remove the
entry from the ack_status_frame.

[ Upstream commit 2e87570be9d2746e7c4e7ab1cc18fd3ca7de2768 ]
Add a helper that allocates the nvme_dev structure up to the point where
we can call nvme_init_ctrl. This pairs with the free_ctrl method and can
thus be used to cleanup the teardown path and make it more symmetric.
Note that this now calls nvme_init_ctrl a lot earlier during probing,
which also means the per-controller character device shows up earlier.
Due to the controller state no commnds can be send on it, but it might
make sense to delay the cdev registration until nvme_init_ctrl_finish.

The reason is early memblock_reserve() in memblock_init() set node id to
MAX_NUMNODES, making NODE_DATA(nid) a NULL dereference in the call chain
reserve_bootmem_region() -> init_reserved_page(). After memblock_init(),
those late calls of memblock_reserve() operate on subregions of memblock
.memory regions. As a result, these reserved regions will be set to the
correct node at the first iteration of memmap_init_reserved_pages().
So set all reserved memblocks on Node#0 at initialization can avoid this
panic.

codec immediately before MCLK is turned off.
Take WM8962 as an example, if MCLK is disabled before DAPM power down
playback stream, FIFO error will arise in WM8962 which will have bad
impact on playback next.

[ Upstream commit 69343ce91435f222052015c5af86b550391bac85 ]
Change the logging of each algorithm from info level to debug level.
On the original devices supported by this code there were typically only
one or two algorithms in a firmware and one or two DSPs so this logging
only used a small number of log lines.
However, for the latest devices there could be 30-40 algorithms in a
firmware and 8 DSPs being loaded in parallel, so using 300+ lines of log
for information that isn't particularly important to have logged.

[ Upstream commit a479b44ac0a0ac25cd48e5356200078924d78022 ]
The ACPI setting for a GPIO default state has higher priority than the
flag passed to devm_gpiod_get_optional() so ACPI can override the
GPIOD_OUT_LOW. Explicitly set the GPIO low when hard resetting.
Although GPIOD_OUT_LOW can't be relied on this doesn't seem like a
reason to stop passing it to devm_gpiod_get_optional(). So we still pass
it to state our intent, but can deal with it having no effect.

The CS42L42 can accept very short reset pulses of a few microseconds
but there's no reason to force a very short pulse.
Allow a wide range for the usleep_range() so it can be relaxed about
the choice of timing source.

Commit 151e887d8ff9 ("veth: Fixing transmit return status for dropped
packets") exposed the fact that bpf_clone_redirect is capable of
returning raw NET_XMIT_XXX return codes.
This is in the conflict with its UAPI doc which says the following:
"0 on success, or a negative error in case of failure."
Update the UAPI to reflect the fact that bpf_clone_redirect can
return positive error numbers, but don't explicitly define
their meaning.

[ Upstream commit 2f9426905a63be7ccf8cd10109caf1848aa0993a ]
The rpmsg pcm device is a device which should support
double buffering.
Found this issue with pipewire. When there is no
SNDRV_PCM_INFO_BATCH flag in driver, the pipewire will
set headroom to be zero, and because rpmsg pcm device
don't support residue report, when the latency setting
is small, the "delay" always larger than "target" in
alsa-pcm.c, that reading next period data is not
scheduled on time.
With SNDRV_PCM_INFO_BATCH flag in driver, the pipewire
will select a smaller period size for device, then
the task of reading next period data will be scheduled
on time.

As explained in errata sheet, in section "2.14.5 Truncation of SPI output
signals after EOT event":
On STM32MP1x, EOT interrupt can be thrown before the true end of
communication.
So we add a delay of a half period to wait the real end of the
transmission.
