+
+From: Siddharth Vadapalli <s-vadapalli@ti.com>
+
+commit 6ee0792d83d5c690205c350825a4c30746c0e0a2 upstream.
+
+The pin for GPMC0_CLK.GPIO0_31 at address 0x000F407C is N22 and not M19.
+Hence, fix the pin name in the comment to avoid confusion.

+Subject: batman-adv: bla: only purge non-released claims
+
+From: Sven Eckelmann <sven@narfation.org>
+
+commit cf6b604011591865ae39ac82de8978c1120d17af upstream.
+
+When batadv_bla_purge_claims() goes through the list of claims, it is only
+traversing the hash list with an rcu_read_lock(). Due to a potential
+parallel batadv_claim_put(), it can happen that it encounters a claim which
+was actually in the process of being released+freed by
+batadv_claim_release(). In this case, backbone_gw is set to NULL before the
+delayed RCU kfree is started. Calling batadv_bla_claim_get_backbone_gw() is
+then no longer allowed because it would cause a NULL-ptr derefence.
+
+To avoid this, only claims with a valid reference counter must be purged.
+All others are already taken care of.

+
+From: Sven Eckelmann <sven@narfation.org>
+
+commit 4ae1709a314060a196981b344610d023ea841e57 upstream.
+
+When batadv_bla_del_backbone_claims() removes all claims for a backbone, it
+does this by dropping the link entry in the hash list. This list entry
+itself was one of the references which need to be dropped at the same time
+via batadv_claim_put().
+
+But the batadv_claim_put() must not be done before the last access to the
+claim object in this function. Otherwise the claim might be freed already
+by the batadv_claim_release() function before the list entry was dropped.

+Subject: batman-adv: stop caching unowned originator pointers in BAT IV
+
+From: Jiexun Wang <wangjiexun2025@gmail.com>
+
+commit f03e8583532941b07761c5429de7d50766fa3110 upstream.
+
+BAT IV keeps the last-hop neighbor address in each neigh_node, but some
+paths also cache an originator pointer derived from a temporary lookup.
+That pointer is not owned by the neigh_node and may no longer refer to a
+live originator entry after purge handling runs.
+
+Stop storing the auxiliary originator pointer in the BAT IV neighbor
+state. When BAT IV needs the neighbor originator data, resolve it from
+the stored neighbor address and drop the reference again after use.

+Subject: drm/amd/display: Change dither policy for 10 bpc output back to dithering
+
+From: Mario Kleiner <mario.kleiner.de@gmail.com>
+
+commit d65bfb1782304b03862c8c725fac608015dffd36 upstream.
+
+Commit d5df648ec830 ("drm/amd/display: Change dither policy for 10bpc to
+round") degraded display of 12 bpc color precision output to 10 bpc sinks
+by switching 10 bpc output from dithering to "truncate to 10 bpc".
+
+I don't find the argumentation in that commit convincing, but the
+consequences highly unfortunate, especially for applications that
+require effective > 10 bpc precision output of > 10 bpc framebuffers.
+
+The argument wasn't something strong like "there are hardware design
+defects or limitations which require us to work around broken dithering
+to 10 bpc", or "there are some special use cases which do require
+truncation to 10 bpc", but essentially "at some point in the past we
+used truncation in Polaris/Vega times and it looks like it got
+inadvertently changed for Navi, so let's do that again". I couldn't find
+evidence for that in the git commit logs for this. The commit message also
+acknowledges that using dithering "...makes some sense for FP16...
+...but not for ARGB2101010 surfaces..."
+
+The problem with this is that it makes fp16 surfaces, and especially
+rgba16 fixed point surfaces, less useful. These are now well
+supported by Mesa 25.3 and later via OpenGL + EGL, Vulkan/WSI, and by
+OSS AMDVLK Vulkan/WSI/display, and also by GNOME 50 mutter under Wayland,
+and they used to provide more than 10 bpc effective precision at the
+output.
+
+Even for 8 or 10 bpc surfaces, the color pipeline behind the framebuffer,
+e.g., gamma tables, CTM, can be used for color correction and will
+benefit from an effective > 10 bpc output precision via dithering,
+retaining some precision that would get lost on the way through the
+pipeline, e.g., due to non-linear gamma functions.
+
+Scientific apps rely on this for > 10 bpc display precision. Truncating
+to 10 bpc, instead of dithering the pipeline internal 12 bpc precision
+down to 10 bpc, causes a serious loss of precision. This also creates the
+undesirable and slightly absurd situation that using a cheap monitor
+with only 8 bpc input and display panel will yield roughly 12 bpc
+precision via dithering from 12 -> 8 bpc, whereas investment into a
+more expensive monitor with 10 bpc input and native 10 bpc display will
+only yield 10 bpc, even if a fp16 or rgb16 framebuffer and/or a properly
+set up color pipeline (gamma tables, CTM's etc. with more than 10 bpc out
+precision) would allow effective 12 bpc precision output.
+
+Therefore this patch proposes reverting that commit and going back to
+dithering down to 10 bpc, consistent with the behaviour for 6 bpc or 8 bpc
+output.
+
+Successfully tested on AMD Polaris DCE 11.2 and Raven Ridge DCN 1.0 with
+a native 10 bpc capable monitor, outputting a RGBA16 unorm framebuffer and
+measuring resulting color precision with a photometer. No apparent visual
+artifacts or problems were observed, and effective precision was measured
+to be 12 bpc again, as expected.

+
+From: Yang Wang <kevinyang.wang@amd.com>
+
+commit 504f0098ebd074ac8c0ce3471795d79f68e3d265 upstream.
+
+OverDriveTable.FanMinimumPwm and FeatureCtrlMask.PP_OD_FEATURE_FAN_LEGACY_BIT
+have a hard dependency.
+Invalid handling of this dependency leads to disabled thermal monitoring
+and temperature boundary validation.

+
+commit 66085e206431ef88ce36f53c1f53d570790ccc9e upstream.
+
+The uvd/vce/vcn code accesses the IB at predefined offsets without
+checking that the IB is large enough. Check the bounds here. The caller
+is responsible for making sure it can handle arbitrary return values.
+
+Also make the idx a uint32_t to prevent overflows causing the condition
+to fail.

+Subject: drm/amdgpu: gate VM CPU HDP flush on reset lock
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Chenglei Xie <Chenglei.Xie@amd.com>
+
+commit ddda81c4d7e71e41b1be91d921fd85747eddbd12 upstream.
+
+During GPU reset, the application could still run CPU page table updates. Each commit called
+amdgpu_device_flush_hdp(), which on SR-IOV sends work through the KIQ ring.
+That can advance sync_seq while the GPU is being reset,
+leaving fence writeback out of sync and causing amdgpu_fence_emit_polling()
+to time out on later KIQ use.
+
+Fix:
+amdgpu_vm_cpu_commit():
+ Reset will flush HDP anyway, the HDP flush in amdgpu_vm_cpu_commit() can be skipped
+ when a reset is ongoging.
+ Take reset_domain->sem with down_read_trylock() before amdgpu_device_flush_hdp().
+ If the reset path holds the write lock, skip the HDP flush so no HDP-related HW
+ access (including KIQ) runs during reset; state is re-established after reset.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: John B. Moore <jbmoore61@gmail.com>
+
+commit 7bbfb2559bcec39d1a4e1182d931a2046112c352 upstream.
+
+Remove the BUG_ON(flags & AMDGPU_FENCE_FLAG_64BIT) assertion from
+gfx_v9_0_ring_emit_fence_kiq(). The KIQ hardware supports 64-bit
+fence writes; the 32-bit writeback address constraint is an
+upper-layer convention, not a hardware limitation. The check serves
+no purpose and should not be present.
+
+Found by code inspection while investigating related BUG_ON
+assertions in the GFX and compute ring emission paths.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: John B. Moore <jbmoore61@gmail.com>
+
+commit 78d2e624fa073c14970aa097adcf3ea31c157a66 upstream.
+
+sdma_v4_0_ring_emit_fence() contains two BUG_ON(addr & 0x3) assertions
+that verify fence writeback addresses are dword-aligned. These
+assertions can be reached from unprivileged userspace via crafted
+DRM_IOCTL_AMDGPU_CS submissions, causing a fatal kernel panic in a
+scheduler worker thread.
+
+Replace both BUG_ON() calls with WARN_ON() to log the condition without
+crashing the kernel. A misaligned fence address at this point indicates
+a driver bug, but crashing the kernel is never the correct response when
+the assertion is reachable from userspace.
+
+The CS IOCTL path is the correct place to filter invalid submissions;
+the ring emission callback is too late to do anything about it.

+
+In the case that only one of lo/hi is valid, the patching could result

+Subject: drm/amdgpu: zero-initialize GART table on allocation
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Philip Yang <Philip.Yang@amd.com>
+
+commit e6c2e6c2e1fa066968a16aca1cb66cd1bdde7741 upstream.
+
+GART TLB is flushed after unmapping but not after mapping. Since
+amdgpu_bo_create_kernel() does not zero-initialize the buffer, when a
+single PTE is written the TLB may speculatively load other uninitialized
+entries from the same cacheline. Those garbage entries can appear valid,
+and a subsequent write to another PTE in the same cacheline may cause the
+GPU to use a stale garbage PTE from the TLB.
+
+Fix this by calling memset_io() to zero-initialize the GART table with
+gart_pte_flags immediately after allocation.
+
+Using AMDGPU_GEM_CREATE_VRAM_CLEARED, SDMA-based clear will not work
+since SDMA needs GART to be initialized to work.

+commit ad52d61d82181dbdb7f05826de38352d5e550cc2 upstream.
+
+KFD VRAM allocations set AMDGPU_GEM_CREATE_VRAM_WIPE_ON_RELEASE

+Subject: drm/gem: Fix inconsistent plane dimension calculation in drm_gem_fb_init_with_funcs()
+
+From: Ashutosh Desai <ashutoshdesai993@gmail.com>
+
+commit 3d4c2268bd7243c3780fe32bf24ff876da272acf upstream.
+
+drm_gem_fb_init_with_funcs() computes sub-sampled plane dimensions
+using plain integer division:
+
+ unsigned int width = mode_cmd->width / (i ? info->hsub : 1);
+ unsigned int height = mode_cmd->height / (i ? info->vsub : 1);
+
+However, the ioctl-level framebuffer_check() in drm_framebuffer.c uses
+drm_format_info_plane_width/height() which round up dimensions via
+DIV_ROUND_UP(). This inconsistency corrupts the subsequent GEM object
+size check for certain pixel format and dimension combinations.
+
+For example, with NV12 (vsub=2) and a 1-pixel-tall framebuffer the
+GEM size validation path sees height=0 instead of height=1. The
+expression (height - 1) then wraps to UINT_MAX as an unsigned int,
+causing min_size to overflow and wrap back to a small value. A tiny
+GEM object therefore passes the size guard, yet when the GPU accesses
+the chroma plane it will read or write memory beyond the object's
+bounds.
+
+Fix by replacing the open-coded divisions with drm_format_info_plane_width()
+and drm_format_info_plane_height(), which use DIV_ROUND_UP() and match
+the calculation already used in framebuffer_check().
+
+Fixes: 4c3dbb2c312c ("drm: Add GEM backed framebuffer library")

+
+From: Yasuaki Torimaru <yasuakitorimaru@gmail.com>
+
+commit 47cbfe2608314b833ad61a65827d8fb363bc2d2d upstream.
+
+msm_ioctl_gem_info_get_metadata() always returns 0 regardless of
+errors. When copy_to_user() fails or the user buffer is too small,
+the error code stored in ret is ignored because the function
+unconditionally returns 0. This causes userspace to believe the
+ioctl succeeded when it did not.
+
+Additionally, kmemdup() can return NULL on allocation failure, but
+the return value is not checked. This leads to a NULL pointer
+dereference in the subsequent copy_to_user() call.
+
+Add the missing NULL check for kmemdup() and return ret instead of 0.
+
+Note that the SET counterpart (msm_ioctl_gem_info_set_metadata)
+correctly returns ret.

+
+From: Icenowy Zheng <zhengxingda@iscas.ac.cn>
+
+commit 570cf799e87ae805eacfab3b4ba66676b5fccdb6 upstream.
+
+When preparing the panel, it seems that it always expects commands to be
+transferred in LP mode. However, the disable function removes the
+MIPI_DSI_MODE_LPM flag, and no other function re-adds it.
+
+As the unprepare function contains no DSI commands, re-adding the flag
+just after disabling the panel should be safe. Add the code re-adding
+the flag after the two commands for disabling the panel are sent.
+
+This fixes error messages shown in kernel log when unblanking on
+mt8183-kukui-kodama-sku32 device.

+Subject: drm/panel: himax-hx83102: restore MODE_LPM after sending disable cmds
+
+From: Icenowy Zheng <zhengxingda@iscas.ac.cn>
+
+commit 2d4e80271f784aa0c7b17676e9762c7e8156be1c upstream.
+
+When preparing the panel, it seems that it always expects commands to be
+transferred in LP mode. However, the disable function removes the
+MIPI_DSI_MODE_LPM flag, and no other function re-adds it.
+
+As the unprepare function contains no DSI commands, re-adding the flag
+just after disabling the panel should be safe. Add the code re-adding
+the flag after the two commands for disabling the panel are sent.
+
+This fixes screen unblanking (after blanking once) on
+mt8188-geralt-ciri-sku1 device.

+Subject: sched_ext: Use HK_TYPE_DOMAIN_BOOT to detect isolcpus= domain isolation
+
+From: Andrea Righi <arighi@nvidia.com>
+
+commit 6ae315d37924435516d697ea7dde0b799a5928e0 upstream.
+
+scx_enable() refuses to attach a BPF scheduler when isolcpus=domain is
+in effect by comparing housekeeping_cpumask(HK_TYPE_DOMAIN) against
+cpu_possible_mask.
+
+Since commit 27c3a5967f05 ("sched/isolation: Convert housekeeping
+cpumasks to rcu pointers"), HK_TYPE_DOMAIN's cpumask is RCU protected
+and dereferencing it requires either RCU read lock, the cpu_hotplug
+write lock, or the cpuset lock; scx_enable() holds none of these, so
+booting with isolcpus=domain and attaching any BPF scheduler triggers
+the following lockdep splat:
+
+ =============================
+ WARNING: suspicious RCU usage
+ -----------------------------
+ kernel/sched/isolation.c:60 suspicious rcu_dereference_check() usage!
+
+ 1 lock held by scx_flash/281:

+
+In addition, commit 03ff73510169 ("cpuset: Update HK_TYPE_DOMAIN cpumask
+from cpuset") made HK_TYPE_DOMAIN include cpuset isolated partitions as
+well, which means the current check also rejects BPF schedulers when a
+cpuset partition is active. That contradicts the original intent of
+commit 9f391f94a173 ("sched_ext: Disallow loading BPF scheduler if
+isolcpus= domain isolation is in effect"), which explicitly noted that
+cpuset partitions are honored through per-task cpumasks and should not
+be rejected.
+
+Switch to housekeeping_enabled(HK_TYPE_DOMAIN_BOOT), which reads only
+the housekeeping flag bit (no RCU dereference) and reflects exactly the
+boot-time isolcpus= configuration that the error message refers to.

+Subject: sctp: revalidate list cursor after sctp_sendmsg_to_asoc() in SCTP_SENDALL
+
+From: Ben Morris <bmorris@anthropic.com>
+
+commit abb5f36771cc4c05899b34000829a787572a8817 upstream.
+
+The SCTP_SENDALL path in sctp_sendmsg() iterates ep->asocs with
+list_for_each_entry_safe(), which caches the next entry in @tmp before
+the loop body runs. The body calls sctp_sendmsg_to_asoc(), which may
+drop the socket lock inside sctp_wait_for_sndbuf().
+
+While the lock is dropped, another thread can SCTP_SOCKOPT_PEELOFF the
+association cached in @tmp, migrating it to a new endpoint via
+sctp_sock_migrate() (list_del_init() + list_add_tail() to
+newep->asocs), and optionally close the new socket which frees the
+association via kfree_rcu(). The cached @tmp can also be freed by a
+network ABORT for that association, processed in softirq while the
+lock is dropped.
+
+sctp_wait_for_sndbuf() revalidates @asoc (the current entry) on re-lock
+via the "sk != asoc->base.sk" and "asoc->base.dead" checks, but nothing
+revalidates @tmp. After a successful return, the iterator advances to
+the stale @tmp, yielding either a use-after-free (if the peeled socket
+was closed) or a list-walk onto the new endpoint's list head (type
+confusion of &newep->asocs as a struct sctp_association *).
+
+Both are reachable from CapEff=0; the type-confusion path gives
+controlled indirect call via the outqueue.sched->init_sid pointer.
+
+Fix by re-deriving @tmp from @asoc after sctp_sendmsg_to_asoc()
+returns. @asoc is known to still be on ep->asocs at that point: the
+only callers that list_del an association from ep->asocs are
+sctp_association_free() (which sets asoc->base.dead) and
+sctp_assoc_migrate() (which changes asoc->base.sk), and
+sctp_wait_for_sndbuf() checks both under the lock before any
+successful return; a tripped check propagates as err < 0 and the loop
+bails before the re-derive.
+
+The SCTP_ABORT path in sctp_sendmsg_check_sflags() returns 0 and the
+loop hits 'continue' before sctp_sendmsg_to_asoc() is ever called, so
+the @tmp cached by list_for_each_entry_safe() still covers the
+lock-held free that ba59fb027307 ("sctp: walk the list of asoc
+safely") was added for.

+Subject: spi: bcmbca-hsspi: fix controller deregistration
+
+From: Johan Hovold <johan@kernel.org>
+
+commit c3d97c3320b9a1ebbd6119857341be034f7b3efc upstream.
+
+Make sure to deregister the controller before disabling underlying
+resources like interrupts during driver unbind to allow SPI drivers to
+do I/O during deregistration.
+
+Note that clocks were also disabled before the recent commit
+e532e21a246d ("spi: bcm63xx-hsspi: Simplify clock handling with
+devm_clk_get_enabled()").
+
+Fixes: a38a2233f23b ("spi: bcmbca-hsspi: Add driver for newer HSSPI controller")

+
+commit 5b1689a41f02955c5361944f748a4812a6ff9307 upstream.

+during driver unbind to avoid unclocked register access and unbalanced
+clock disable.
+
+Also restore the autosuspend setting.

+
+From: Johan Hovold <johan@kernel.org>
+
+commit 706b3dc2ac7a998c55e14b3fd2e8f934c367e6e0 upstream.
+
+The state machine work is scheduled by the interrupt handler and
+therefore needs to be cancelled after disabling interrupts to avoid a
+potential use-after-free.
+
+Fixes: 984836621aad ("spi: mpc52xx: Add cancel_work_sync before module remove")
