[ Upstream commit f9c35f4fffc6cb5bbb23f546f48c045aef012518 ]

GFX v11 changes RB_BACKEND_DISABLE related registers from per SA to global ones. The approach to query active rb bitmap needs to be changed accordingly. Query per SE setting returns wrong active RB bitmap especially in the case when some of SA are disabled. With the new approach, driver will generate the active rb bitmap based on active SA bitmap and global active RB bitmap.

commit a4833e3abae132d613ce7da0e0c9a9465d1681fa upstream.

The rpcgss_context trace event acceptor field is a dynamically sized string that records the "data" parameter. But this parameter is also dependent on the "len" field to determine the size of the data.

It needs to use __string_len() helper macro where the length can be passed in. It also incorrectly uses strncpy() to save it instead of __assign_str(). As these macros can change, it is not wise to open code them in trace events.

As of commit c759e609030c ("tracing: Remove __assign_str_len()"), __assign_str() can be used for both __string() and __string_len() fields. Before that commit, __assign_str_len() is required to be used. This needs to be noted for backporting. (In actuality, commit c1fa617caeb0 ("tracing: Rework __assign_str() and __string() to not duplicate getting the string") is the commit that makes __string_str_len() obsolete).

commit e871abcda3b67d0820b4182ebe93435624e9c6a4 upstream.

The entropy accounting changes a static key when the RNG has initialized, since it only ever initializes once. Static key changes, however, cannot be made from atomic context, so depending on where the last creditable entropy comes from, the static key change might need to be deferred to a worker.

Previously the code used the execute_in_process_context() helper function, which accounts for whether or not the caller is in_interrupt(). However, that doesn't account for the case where the caller is actually in process context but is holding a spinlock.

This turned out to be the case with input_handle_event() in drivers/input/input.c contributing entropy:

According to Guoyong, it's not really possible to refactor the various drivers to never hold a spinlock there. And in_atomic() isn't reliable.

So, rather than trying to be too fancy, just punt the change in the static key to a workqueue always. There's basically no drawback of doing this, as the code already needed to account for the static key not changing immediately, and given that it's just an optimization, there's not exactly a hurry to change the static key right away, so deferal is fine.

commit 0e45882ca829b26b915162e8e86dbb1095768e9e upstream.

Object debugging tools were sporadically reporting illegal attempts to free a still active i915 VMA object when parking a GT believed to be idle.

[161.359441] ODEBUG: free active (active state 0) object: ffff88811643b958 object type: i915_active hint: __i915_vma_active+0x0/0x50 [i915] [161.360082] WARNING: CPU: 5 PID: 276 at lib/debugobjects.c:514 debug_print_object+0x80/0xb0 ...

That has been tracked down to be happening when another thread is deactivating the VMA inside __active_retire() helper, after the VMA's active counter has been already decremented to 0, but before deactivation of the VMA's object is reported to the object debugging tool.

We could prevent from that race by serializing i915_active_fini() with __active_retire() via ref->tree_lock, but that wouldn't stop the VMA from being used, e.g. from __i915_vma_retire() called at the end of __active_retire(), after that VMA has been already freed by a concurrent i915_vma_destroy() on return from the i915_active_fini(). Then, we should rather fix the issue at the VMA level, not in i915_active.

Since __i915_vma_parked() is called from __gt_park() on last put of the GT's wakeref, the issue could be addressed by holding the GT wakeref long enough for __active_retire() to complete before that wakeref is released and the GT parked.

I believe the issue was introduced by commit d93939730347 ("drm/i915: Remove the vma refcount") which moved a call to i915_active_fini() from a dropped i915_vma_release(), called on last put of the removed VMA kref, to i915_vma_parked() processing path called on last put of a GT wakeref. However, its visibility to the object debugging tool was suppressed by a bug in i915_active that was fixed two weeks later with commit e92eb246feb9 ("drm/i915/active: Fix missing debug object activation").

A VMA associated with a request doesn't acquire a GT wakeref by itself. Instead, it depends on a wakeref held directly by the request's active intel_context for a GT associated with its VM, and indirectly on that intel_context's engine wakeref if the engine belongs to the same GT as the VMA's VM. Those wakerefs are released asynchronously to VMA deactivation.

Fix the issue by getting a wakeref for the VMA's GT when activating it, and putting that wakeref only after the VMA is deactivated. However, exclude global GTT from that processing path, otherwise the GPU never goes idle. Since __i915_vma_retire() may be called from atomic contexts, use async variant of wakeref put. Also, to avoid circular locking dependency, take care of acquiring the wakeref before VM mutex when both are needed.

v7: Add inline comments with justifications for: - using untracked variants of intel_gt_pm_get/put() (Nirmoy), - using async variant of _put(), - not getting the wakeref in case of a global GTT, - always getting the first wakeref outside vm->mutex. v6: Since __i915_vma_active/retire() callbacks are not serialized, storing a wakeref tracking handle inside struct i915_vma is not safe, and there is no other good place for that. Use untracked variants of intel_gt_pm_get/put_async(). v5: Replace "tile" with "GT" across commit description (Rodrigo), - avoid mentioning multi-GT case in commit description (Rodrigo), - explain why we need to take a temporary wakeref unconditionally inside i915_vma_pin_ww() (Rodrigo). v4: Refresh on top of commit 5e4e06e4087e ("drm/i915: Track gt pm wakerefs") (Andi), - for more easy backporting, split out removal of former insufficient workarounds and move them to separate patches (Nirmoy). - clean up commit message and description a bit. v3: Identify root cause more precisely, and a commit to blame, - identify and drop former workarounds, - update commit message and description. v2: Get the wakeref before VM mutex to avoid circular locking dependency, - drop questionable Fixes: tag.

[ Commit 7e50262229faad0c7b8c54477cd1c883f31cc4a7 upstream ]

The native EFI entrypoint does not take a struct boot_params from the loader, but instead, it constructs one from scratch, using the setup header data placed at the start of the image.

This setup header is placed in a way that permits legacy loaders to manipulate the contents (i.e., to pass the kernel command line or the address and size of an initial ramdisk), but EFI boot does not use it in that way - it only copies the contents that were placed there at build time, but EFI loaders will not (and should not) manipulate the setup header to configure the boot. (Commit 63bf28ceb3ebbe76 "efi: x86: Wipe setup_data on pure EFI boot" deals with some of the fallout of using setup_data in a way that breaks EFI boot.)

Given that none of the non-zero values that are copied from the setup header into the EFI stub's struct boot_params are relevant to the boot now that the EFI stub no longer enters via the legacy decompressor, the copy can be omitted altogether.

The section header flags for alignment are documented in the PE/COFF spec as being applicable to PE object files only, not to PE executables such as the Linux bzImage, so let's drop them from the PE header.

Now that the EFI stub decompresses the kernel and hands over to the decompressed image directly, there is no longer a need to provide a decompression buffer as part of the .BSS allocation of the PE/COFF image. It also means the PE/COFF image can be loaded anywhere in memory, and setting the preferred image base is unnecessary. So drop the handling of this from the header and from the build tool.

The x86 boot image generation tool assign a default value to startup_64 and subsequently parses the actual value from zoffset.h but it never actually uses the value anywhere. So remove this code.

Tweak the linker script so that the value of _edata represents the decompressor binary's file size rounded up to the appropriate alignment. This removes the need to calculate it in the build tool, and will make it easier to refer to the file size from the header directly in subsequent changes to the PE header layout.

While adding _edata to the sed regex that parses the compressed vmlinux's symbol list, tweak the regex a bit for conciseness.

This change has no impact on the resulting bzImage binary when configured with CONFIG_EFI_STUB=y.

[ Commit 3e3eabe26dc88692d34cf76ca0e0dd331481cc15 upstream ]

Align x86 with other EFI architectures, and increase the section alignment to the EFI page size (4k), so that firmware is able to honour the section permission attributes and map code read-only and data non-executable.

There are a number of requirements that have to be taken into account: - the sign tools get cranky when there are gaps between sections in the file view of the image - the virtual offset of each section must be aligned to the image's section alignment - the file offset *and size* of each section must be aligned to the image's file alignment - the image size must be aligned to the section alignment - each section's virtual offset must be greater than or equal to the size of the headers.

In order to meet all these requirements, while avoiding the need for lots of padding to accommodate the .compat section, the latter is placed at an arbitrary offset towards the end of the image, but aligned to the minimum file alignment (512 bytes). The space before the .text section is therefore distributed between the PE header, the .setup section and the .compat section, leaving no gaps in the file coverage, making the signing tools happy.

[ Upstream commit f969eb84ce482331a991079ab7a5c4dc3b7f89bf ]

nft_unregister_expr() can concurrent with __nft_expr_type_get(), and there is not any protection when iterate over nf_tables_expressions list in __nft_expr_type_get(). Therefore, there is potential data-race of nf_tables_expressions list entry.

Use list_for_each_entry_rcu() to iterate over nf_tables_expressions list in __nft_expr_type_get(), and use rcu_read_lock() in the caller nft_expr_type_get() to protect the entire type query process.

[ Upstream commit 751de2012eafa4d46d8081056761fa0e9cc8a178 ]

For historical reasons, when bridge device is in promisc mode, packets that are directed to the taps follow bridge input hook path. This patch adds a workaround to reset conntrack for these packets.

Jianbo Liu reports warning splats in their test infrastructure where cloned packets reach the br_netfilter input hook to confirm the conntrack object.

Scratch one bit from BR_INPUT_SKB_CB to annotate that this packet has reached the input hook because it is passed up to the bridge device to reach the taps.

[ Upstream commit 283454c8a123072e5c386a5a2b5fc576aa455b6f ]

When we call recv() for AF_UNIX socket, we first peek one skb and calls manage_oob() to check if the skb is sent with MSG_OOB.

However, when we fetch the next (and the following) skb, manage_oob() is not called now, leading a wrong behaviour.

Let's say a socket send()s "hello" with MSG_OOB and the peer tries to recv() 5 bytes with MSG_PEEK. Here, we should get only "hell" without 'o', but actually not:

...

...

from socket import * c1, c2 = socketpair(AF_UNIX, SOCK_STREAM) c1.send(b'hello', MSG_OOB)

5

...

...

c2.recv(5, MSG_PEEK)

b'hello'

The first skb fills 4 bytes, and the next skb is peeked but not properly checked by manage_oob().

Let's move up the again label to call manage_oob() for evry skb.

With this patch:

...

...

from socket import * c1, c2 = socketpair(AF_UNIX, SOCK_STREAM) c1.send(b'hello', MSG_OOB)

5

...

...

c2.recv(5, MSG_PEEK)

b'hell'

The cited patch introduces the concept of buckets in LAG in hash mode. However, the patch doesn't clear the number of buckets in the LAG deactivation. This results in using the wrong number of buckets in case user create a hash mode LAG and afterwards create a non-hash mode LAG.

Hence, restore buckets number to default after hash mode LAG deactivation.

The check for flags is done to not pass empty lookups to adding switch rule functions. Since metadata is always added to lookups there is no need to check against the flag.

It is also fixing the problem with such rule: $ tc filter add dev gtp_dev ingress protocol ip prio 0 flower \ enc_dst_port 2123 action drop Switch block in case of GTP can't parse the destination port, because it should always be set to GTP specific value. The same with ethertype. The result is that there is no other matching criteria than GTP tunnel. In this case flags is 0, rule can't be added only because of defensive check against flags.

This switch intellectual property provides a bit on the ARL global control register which controls allowing mirroring frames which are received on the local port (monitor port). This bit is unset after reset.

This ability must be enabled to fully support the port mirroring feature on this switch intellectual property.

Therefore, this patch fixes the traffic not being reflected on a port, which would be configured like below:

tc qdisc add dev swp0 clsact

tc filter add dev swp0 ingress matchall skip_sw \ action mirred egress mirror dev swp0

As a side note, this configuration provides the hairpinning feature for a single port.

[ Upstream commit 2d8527f2f911fab84aec04df4788c0c23af3df48 ]

A race condition exists in ccw_device_set_online() that can cause the online process to fail, leaving the affected device in an inconsistent state. As a result, subsequent attempts to set that device online fail with return code ENODEV.

The problem occurs when a path verification request arrives after a wait for final device state completed, but before the result state is evaluated.

Fix this by ensuring that the CCW-device lock is held between determining final state and checking result state.

Note that since:

commit 2297791c92d0 ("s390/cio: dont unregister subchannel from child-drivers")

path verification requests are much more likely to occur during boot, resulting in an increased chance of this race condition occurring.

[ Upstream commit 0ac448e0d29d6ba978684b3fa2e3ac7294ec2475 ]

Prevent KVM hang when a Solidgm P44 Pro NVMe is passed through to a guest via IOMMU and the guest is subsequently rebooted.

A similar issue was identified and patched by 51ba09452d11 ("PCI: Delay after FLR of Intel DC P3700 NVMe") and the same fix can be applied for this case. (Intel spun off their NAND and SSD business as Solidigm and sold it to SK Hynix in late 2021.)

A follow on patch will introduce CONFIG_USB_PCI_AMD governing the AMD quirk and adding its compile time dependency on HAS_IOPORT. In order to minimize the number of #ifdefs in C files and make that patch easier to read first group the code together. This is pure code movement no functional change is intended.

[ Upstream commit 6e743781d62e28f5fa095e5f31f878819622c143 ]

This driver was originally developed for the Focusrite Scarlett Gen 2 series, but now also supports the Scarlett Gen 3 series, the Clarett 8Pre USB, and the Clarett+ 8Pre. The messages output by the driver on initialisation and error include the identifying text "Scarlett Gen 2/3", but this is no longer accurate, and writing "Scarlett Gen 2/3/Clarett USB/Clarett+" would be unwieldy.

Add series_name field to the scarlett2_device_entry struct so that concise and accurate messages can be output.

From: Hardik Gajjar hgajjar@de.adit-jv.com

[ Upstream commit 5a1ccf0c72cf917ff3ccc131d1bb8d19338ffe52 ]

This patch introduces a new USB quirk, USB_QUIRK_SHORT_SET_ADDRESS_REQ_TIMEOUT, which modifies the timeout value for the SET_ADDRESS request. The standard timeout for USB request/command is 5000 ms, as recommended in the USB 3.2 specification (section 9.2.6.1).

However, certain scenarios, such as connecting devices through an APTIV hub, can lead to timeout errors when the device enumerates as full speed initially and later switches to high speed during chirp negotiation.

In such cases, USB analyzer logs reveal that the bus suspends for 5 seconds due to incorrect chirp parsing and resumes only after two consecutive timeout errors trigger a hub driver reset.

Packet(54) Dir(?) Full Speed J(997.100 us) Idle( 2.850 us) _______| Time Stamp(28 . 105 910 682) _______|_____________________________________________________________Ch0 Packet(55) Dir(?)

This 5-second delay in device enumeration is undesirable, particularly in automotive applications where quick enumeration is crucial (ideally within 3 seconds).

The newly introduced quirks provide the flexibility to align with a 3-second time limit, as required in specific contexts like automotive applications.

By reducing the SET_ADDRESS request timeout to 500 ms, the system can respond more swiftly to errors, initiate rapid recovery, and ensure efficient device enumeration. This change is vital for scenarios where rapid smartphone enumeration and screen projection are essential.

To use the quirk, please write "vendor_id:product_id:p" to /sys/bus/usb/drivers/hub/module/parameter/quirks

For example, echo "0x2c48:0x0132:p" > /sys/bus/usb/drivers/hub/module/parameters/quirks"

Currently, the regulator framework informs us before calling into their unused cleanup paths, which eases at least some debugging. The same could be beneficial for clocks, so that random shutdowns shortly after most initcalls are done can be less of a guess.

Add a pr_info before disabling unused clocks to do so.

The first thread is walking the clk tree and calling clk_pm_runtime_get() to power on devices required to read the clk hardware via struct clk_ops::is_enabled(). This thread holds the clk prepare_lock, and is trying to runtime PM resume a device, when it finds that the device is in the process of resuming so the thread schedule()s away waiting for the device to finish resuming before continuing. The second thread is runtime PM resuming the same device, but the runtime resume callback is calling clk_prepare(), trying to grab the prepare_lock waiting on the first thread.

This is a classic ABBA deadlock. To properly fix the deadlock, we must never runtime PM resume or suspend a device with the clk prepare_lock held. Actually doing that is near impossible today because the global prepare_lock would have to be dropped in the middle of the tree, the device runtime PM resumed/suspended, and then the prepare_lock grabbed again to ensure consistency of the clk tree topology. If anything changes with the clk tree in the meantime, we've lost and will need to start the operation all over again.

Luckily, most of the time we're simply incrementing or decrementing the runtime PM count on an active device, so we don't have the chance to schedule away with the prepare_lock held. Let's fix this immediate problem that can be triggered more easily by simply booting on Qualcomm sc7180.

Introduce a list of clk_core structures that have been registered, or are in the process of being registered, that require runtime PM to operate. Iterate this list and call clk_pm_runtime_get() on each of them without holding the prepare_lock during clk_disable_unused(). This way we can be certain that the runtime PM state of the devices will be active and resumed so we can't schedule away while walking the clk tree with the prepare_lock held. Similarly, call clk_pm_runtime_put() without the prepare_lock held to properly drop the runtime PM reference. We remove the calls to clk_pm_runtime_{get,put}() in this path because they're superfluous now that we know the devices are runtime resumed.

[ Upstream commit 20498d52c9c1a68b1d92c42bce1dc893d3e74f30 ]

Commit e4c23e19aa2a ("clk: mediatek: Register clock gate with device") introduces a helper function for the sole purpose of propagating a struct device pointer to the clk API when registering the mtk-gate clocks to take advantage of Runtime PM when/where needed and where a power domain is defined in devicetree.

Function mtk_clk_register_gates() then becomes a wrapper around the new mtk_clk_register_gates_with_dev() function that will simply pass NULL as struct device: this is essential when registering drivers with CLK_OF_DECLARE instead of as a platform device, as there will be no struct device to pass... but we can as well simply have only one function that always takes such pointer as a param and pass NULL when unavoidable.

This commit removes the mtk_clk_register_gates() wrapper and renames mtk_clk_register_gates_with_dev() to the former and all of the calls to either of the two functions were fixed in all drivers in order to reflect this change; also, to improve consistency with other kernel functions, the pointer to struct device was moved as the first param.

Since a lot of MediaTek clock drivers are actually registering as a platform device, but were still registering the mtk-gate clocks without passing any struct device to the clock framework, they've been changed to pass a valid one now, as to make all those platforms able to use runtime power management where available.

[ Upstream commit 2f7b1d8b5505efb0057cd1ab85fca206063ea4c3 ]

mt8183-mfgcfg has a mutual dependency with genpd during the probing stage, which leads to a deadlock in the following call stack:

CPU0: genpd_lock --> clk_prepare_lock genpd_power_off_work_fn() genpd_lock() generic_pm_domain::power_off() clk_unprepare() clk_prepare_lock()

CPU1: clk_prepare_lock --> genpd_lock clk_register() __clk_core_init() clk_prepare_lock() clk_pm_runtime_get() genpd_lock()

Do a runtime PM get at the probe function to make sure clk_register() won't acquire the genpd lock. Instead of only modifying mt8183-mfgcfg, do this on all mediatek clock controller probings because we don't believe this would cause any regression.

Verified on MT8183 and MT8192 Chromebooks.

[ Upstream commit 9543f6e26634537997b6e909c20911b7bf4876de ]

Fix cpuid_deps[] to list the correct dependencies for GFNI, VAES, and VPCLMULQDQ. These features don't depend on AVX512, and there exist CPUs that support these features but not AVX512. GFNI actually doesn't even depend on AVX.

This prevents GFNI from being unnecessarily disabled if AVX is disabled to mitigate the GDS vulnerability.

This also prevents all three features from being unnecessarily disabled if AVX512VL (or its dependency AVX512F) were to be disabled, but it looks like there isn't any case where this happens anyway.

commit aaef73821a3b0194a01bd23ca77774f704a04d40 upstream.

Commit 6d98eb95b450 ("binder: avoid potential data leakage when copying txn") introduced changes to how binder objects are copied. In doing so, it unintentionally removed an offset alignment check done through calls to binder_alloc_copy_from_buffer() -> check_buffer().

These calls were replaced in binder_get_object() with copy_from_user(), so now an explicit offset alignment check is needed here. This avoids later complications when unwinding the objects gets harder.

It is worth noting this check existed prior to commit 7a67a39320df ("binder: add function to copy binder object from buffer"), likely removed due to redundancy at the time.

commit c38fa07dc69f0b9e6f43ecab96dc7861a70c827c upstream.

Currently we don't configure correctly the wake events after unplug of device router. What can happen is that the downstream ports of host router will be configured to wake on: USB4-wake and wake-on-disconnect, but not on wake-on-connect. This may cause the later plugged device not to wake the domain and fail in enumeration. Fix this by clearing downstream port's "USB4 Port is Configured" bit, after unplug of a device router.

commit 13c785323b36b845300b256d0e5963c3727667d7 upstream.

If there is a stuck irq that the handler doesn't address, returning IRQ_HANDLED unconditionally makes it impossible for the irq core to detect the problem and disable the irq. So only return IRQ_HANDLED if an event was handled.

A stuck irq is still problematic, but with this change at least it only makes the UART nonfunctional instead of occupying the (usually only) CPU by 100% and so stall the whole machine.

commit cf16ffa17c398434a77b8a373e69287c95b60de2 upstream.

Update the USB serial option driver to support Longsung U8300/U9300.

For U8300

Interface 4 is used by for QMI interface in stock firmware of U8300, the router which uses U8300 modem. Interface 5 is used by for ADB interface in stock firmware of U8300, the router which uses U8300 modem.

Interface mapping is: 0: unknown (Debug), 1: AT (Modem), 2: AT, 3: PPP (NDIS / Pipe), 4: QMI, 5: ADB

For U9300

Interface 1 is used by for ADB interface in stock firmware of U9300, the router which uses U9300 modem. Interface 4 is used by for QMI interface in stock firmware of U9300, the router which uses U9300 modem.

Interface mapping is: 0: ADB, 1: AT (Modem), 2: AT, 3: PPP (NDIS / Pipe), 4: QMI

Note: Interface 3 of some models of the U9300 series can send AT commands.

This is due to the USB device still cause port change event after xHCI is shuted down:

The port change event is caused by LPM transition, so disabling LPM at shutdown to make sure the device is in U0 for warmboot.

commit a90bca2228c0646fc29a72689d308e5fe03e6d78 upstream.

The sysfs_break_active_protection() routine has an obvious reference leak in its error path. If the call to kernfs_find_and_get() fails then kn will be NULL, so the companion sysfs_unbreak_active_protection() routine won't get called (and would only cause an access violation by trying to dereference kn->parent if it was called). As a result, the reference to kobj acquired at the start of the function will never be released.

Fix the leak by adding an explicit kobject_put() call when kn is NULL.

commit 9e985cbf2942a1bb8fcef9adc2a17d90fd7ca8ee upstream.

Drop support for virtualizing adaptive PEBS, as KVM's implementation is architecturally broken without an obvious/easy path forward, and because exposing adaptive PEBS can leak host LBRs to the guest, i.e. can leak host kernel addresses to the guest.

Bug #1 is that KVM doesn't account for the upper 32 bits of IA32_FIXED_CTR_CTRL when (re)programming fixed counters, e.g fixed_ctrl_field() drops the upper bits, reprogram_fixed_counters() stores local variables as u8s and truncates the upper bits too, etc.

Bug #2 is that, because KVM _always_ sets precise_ip to a non-zero value for PEBS events, perf will _always_ generate an adaptive record, even if the guest requested a basic record. Note, KVM will also enable adaptive PEBS in individual *counter*, even if adaptive PEBS isn't exposed to the guest, but this is benign as MSR_PEBS_DATA_CFG is guaranteed to be zero, i.e. the guest will only ever see Basic records.

Bug #3 is in perf. intel_pmu_disable_fixed() doesn't clear the upper bits either, i.e. leaves ICL_FIXED_0_ADAPTIVE set, and intel_pmu_enable_fixed() effectively doesn't clear ICL_FIXED_0_ADAPTIVE either. I.e. perf _always_ enables ADAPTIVE counters, regardless of what KVM requests.

Bug #4 is that adaptive PEBS *might* effectively bypass event filters set by the host, as "Updated Memory Access Info Group" records information that might be disallowed by userspace via KVM_SET_PMU_EVENT_FILTER.

Bug #5 is that KVM doesn't ensure LBR MSRs hold guest values (or at least zeros) when entering a vCPU with adaptive PEBS, which allows the guest to read host LBRs, i.e. host RIPs/addresses, by enabling "LBR Entries" records.

Disable adaptive PEBS support as an immediate fix due to the severity of the LBR leak in particular, and because fixing all of the bugs will be non-trivial, e.g. not suitable for backporting to stable kernels.

Note! This will break live migration, but trying to make KVM play nice with live migration would be quite complicated, wouldn't be guaranteed to work (i.e. KVM might still kill/confuse the guest), and it's not clear that there are any publicly available VMMs that support adaptive PEBS, let alone live migrate VMs that support adaptive PEBS, e.g. QEMU doesn't support PEBS in any capacity.

The reason is swsusp_save() -> copy_data_pages() -> page_is_saveable() -> kernel_page_present() assuming that a page is always present when can_set_direct_map() is false (all of rodata_full, debug_pagealloc_enabled() and arm64_kfence_can_set_direct_map() false), irrespective of the MEMBLOCK_NOMAP ranges. Such MEMBLOCK_NOMAP regions should not be saved during hibernation.

This problem was introduced by changes to the pfn_valid() logic in commit a7d9f306ba70 ("arm64: drop pfn_valid_within() and simplify pfn_valid()").

Similar to other architectures, drop the !can_set_direct_map() check in kernel_page_present() so that page_is_savable() skips such pages.

Fix this by calling drain_all_pages() instead.

This issue won't occur until commit a6b40850c442 ("mm: hugetlb: replace hugetlb_free_vmemmap_enabled with a static_key"). As it introduced rlock(cpu_hotplug_lock) in dissolve_free_huge_page() code path while lock(pcp_batch_high_lock) is already in the __page_handle_poison().

commit d4c972bff3129a9dd4c22a3999fd8eba1a81531a upstream.

The table of primary plane formats wasn't sorted at all, leading to applications picking our least desirable formats by defaults.

Sort the primary plane formats according to our order of preference.

Nice side-effect of this change is that it makes IGT's kms_atomic plane-invalid-params pass because the test picks the first format which for vmwgfx was DRM_FORMAT_XRGB1555 and uses fb's with odd sizes which make Pixman, which IGT depends on assert due to the fact that our 16bpp formats aren't 32 bit aligned like Pixman requires all formats to be.

Adding any sort of useful debug usually makes it go away, so I hand wrote the function in a line, and debugged the asm.

Every so often pt->memory->ptrs is NULL. This ptrs ptr is set in the nv50_instobj_acquire called from nvkm_kmap.

If Thread A and Thread B both get to nv50_instobj_acquire around the same time, and Thread A hits the refcount_set line, and in lockstep thread B succeeds at refcount_inc_not_zero, there is a chance the ptrs value won't have been stored since refcount_set is unordered. Force a memory barrier here, I picked smp_mb, since we want it on all CPUs and it's write followed by a read.

v2: use paired smp_rmb/smp_wmb.

commit c4a7dc9523b59b3e73fd522c73e95e072f876b16 upstream.

The size of the nilfs_type_by_mode array in the fs/nilfs2/dir.c file is defined as "S_IFMT >> S_SHIFT", but the nilfs_set_de_type() function, which uses this array, specifies the index to read from the array in the same way as "(mode & S_IFMT) >> S_SHIFT".

static void nilfs_set_de_type(struct nilfs_dir_entry *de, struct inode *inode) { umode_t mode = inode->i_mode;

de->file_type = nilfs_type_by_mode[(mode & S_IFMT)>>S_SHIFT]; // oob }

However, when the index is determined this way, an out-of-bounds (OOB) error occurs by referring to an index that is 1 larger than the array size when the condition "mode & S_IFMT == S_IFMT" is satisfied. Therefore, a patch to resize the nilfs_type_by_mode array should be applied to prevent OOB errors.

commit b79d7c14f48083abb3fb061370c0c64a569edf4c upstream.

Since the introduction of the OF bindings, DSA has always had a policy that in case multiple CPU ports are present in the device tree, the numerically smallest one is always chosen.

The MT7530 switch family, except the switch on the MT7988 SoC, has 2 CPU ports, 5 and 6, where port 6 is preferable on the MT7531BE switch because it has higher bandwidth.

The MT7530 driver developers had 3 options: - to modify DSA when the MT7531 switch support was introduced, such as to prefer the better port - to declare both CPU ports in device trees as CPU ports, and live with the sub-optimal performance resulting from not preferring the better port - to declare just port 6 in the device tree as a CPU port

Of course they chose the path of least resistance (3rd option), kicking the can down the road. The hardware description in the device tree is supposed to be stable - developers are not supposed to adopt the strategy of piecemeal hardware description, where the device tree is updated in lockstep with the features that the kernel currently supports.

Now, as a result of the fact that they did that, any attempts to modify the device tree and describe both CPU ports as CPU ports would make DSA change its default selection from port 6 to 5, effectively resulting in a performance degradation visible to users with the MT7531BE switch as can be seen below.

Without preferring port 6:

[ ID][Role] Interval Transfer Bitrate Retr [ 5][TX-C] 0.00-20.00 sec 374 MBytes 157 Mbits/sec 734 sender [ 5][TX-C] 0.00-20.00 sec 373 MBytes 156 Mbits/sec receiver [ 7][RX-C] 0.00-20.00 sec 1.81 GBytes 778 Mbits/sec 0 sender [ 7][RX-C] 0.00-20.00 sec 1.81 GBytes 777 Mbits/sec receiver

With preferring port 6:

[ ID][Role] Interval Transfer Bitrate Retr [ 5][TX-C] 0.00-20.00 sec 1.99 GBytes 856 Mbits/sec 273 sender [ 5][TX-C] 0.00-20.00 sec 1.99 GBytes 855 Mbits/sec receiver [ 7][RX-C] 0.00-20.00 sec 1.72 GBytes 737 Mbits/sec 15 sender [ 7][RX-C] 0.00-20.00 sec 1.71 GBytes 736 Mbits/sec receiver

Using one port for WAN and the other ports for LAN is a very popular use case which is what this test emulates.

As such, this change proposes that we retroactively modify stable kernels (which don't support the modification of the CPU port assignments, so as to let user space fix the problem and restore the throughput) to keep the mt7530 driver preferring port 6 even with device trees where the hardware is more fully described.

commit 06dfcd4098cfdc4d4577d94793a4f9125386da8b upstream.

The commit 40b5d2f15c09 ("net: dsa: mt7530: Add support for EEE features") brought EEE support but did not enable EEE on MT7531 switch MACs. EEE is enabled on MT7531 switch MACs by pulling the LAN2LED0 pin low on the board (bootstrapping), unsetting the EEE_DIS bit on the trap register, or setting the internal EEE switch bit on the CORE_PLL_GROUP4 register. Thanks to SkyLake Huang (黃啟澤) from MediaTek for providing information on the internal EEE switch bit.

There are existing boards that were not designed to pull the pin low. Because of that, the EEE status currently depends on the board design.

The EEE_DIS bit on the trap pertains to the LAN2LED0 pin which is usually used to control an LED. Once the bit is unset, the pin will be low. That will make the active low LED turn on. The pin is controlled by the switch PHY. It seems that the PHY controls the pin in the way that it inverts the pin state. That means depending on the wiring of the LED connected to LAN2LED0 on the board, the LED may be on without an active link.

To not cause this unwanted behaviour whilst enabling EEE on all boards, set the internal EEE switch bit on the CORE_PLL_GROUP4 register.

My testing on MT7531 shows a certain amount of traffic loss when EEE is enabled. That said, I haven't come across a board that enables EEE. So enable EEE on the switch MACs but disable EEE advertisement on the switch PHYs. This way, we don't change the behaviour of the majority of the boards that have this switch. The mediatek-ge PHY driver already disables EEE advertisement on the switch PHYs but my testing shows that it is somehow enabled afterwards. Disabling EEE advertisement before the PHY driver initialises keeps it off.

With this change, EEE can now be enabled using ethtool.

commit 17cf0c2794bdb6f39671265aa18aea5c22ee8c4a upstream.

The response buffer should be allocated in smb2_allocate_rsp_buf before validating request. But the fields in payload as well as smb2 header is used in smb2_allocate_rsp_buf(). This patch add simple buffer size validation to avoid potencial out-of-bounds in request buffer.
