+Subject: ACPI: video: Add backlight=native quirk for Lenovo Slim 7 16ARH7
+
+From: Takashi Iwai <tiwai@suse.de>
+
+[ Upstream commit c901f63dc142c48326931f164f787dfff69273d9 ]
+
+Lenovo Slim 7 16ARH7 is a machine with switchable graphics between AMD
+and Nvidia, and the backlight can't be adjusted properly unless
+acpi_backlight=native is passed. Although nvidia-wmi-backlight is
+present and loaded, this doesn't work as expected at all.
+
+For making it working as default, add the corresponding quirk entry
+with a DMI matching "LENOVO" "82UX".

+Subject: af_packet: avoid a false positive warning in packet_setsockopt()
+
+From: Eric Dumazet <edumazet@google.com>
+
+[ Upstream commit 86d43e2bf93ccac88ef71cee36a23282ebd9e427 ]
+
+Although the code is correct, the following line
+
+ copy_from_sockptr(&req_u.req, optval, len));
+
+triggers this warning :
+
+memcpy: detected field-spanning write (size 28) of single field "dst" at include/linux/sockptr.h:49 (size 16)
+
+Refactor the code to be more explicit.

+
+Historically, the signed integer overflow sanitizer did not work in the
+kernel due to its interaction with `-fwrapv` but this has since been
+changed [1] in the newest version of Clang; It was re-enabled in the
+kernel with Commit 557f8c582a9ba8ab ("ubsan: Reintroduce signed overflow
+sanitizer").
+
+Let's rework this overflow checking logic to not actually perform an
+overflow during the check itself, thus avoiding the UBSAN splat.

+Subject: drm/amd/display: Exit idle optimizations before HDCP execution
+
+From: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com>
+
+[ Upstream commit f30a3bea92bdab398531129d187629fb1d28f598 ]
+
+[WHY]
+PSP can access DCN registers during command submission and we need
+to ensure that DCN is not in PG before doing so.
+
+[HOW]
+Add a callback to DM to lock and notify DC for idle optimization exit.
+It can't be DC directly because of a potential race condition with the
+link protection thread and the rest of DM operation.

+
+[ Upstream commit 49c13b4d2dd4a831225746e758893673f6ae961c ]
+
+This is needed because we want to reset those devices in device-agnostic
+code such as lima_sched.
+In particular, masking irqs will be useful before a hard reset to
+prevent race conditions.

+Subject: drm/lima: mask irqs in timeout path before hard reset
+
+From: Erico Nunes <nunes.erico@gmail.com>
+
+[ Upstream commit a421cc7a6a001b70415aa4f66024fa6178885a14 ]
+
+There is a race condition in which a rendering job might take just long
+enough to trigger the drm sched job timeout handler but also still
+complete before the hard reset is done by the timeout handler.
+This runs into race conditions not expected by the timeout handler.
+In some very specific cases it currently may result in a refcount
+imbalance on lima_pm_idle, with a stack dump such as:
+
+[10136.669170] WARNING: CPU: 0 PID: 0 at drivers/gpu/drm/lima/lima_devfreq.c:205 lima_devfreq_record_idle+0xa0/0xb0
+...
+[10136.669459] pc : lima_devfreq_record_idle+0xa0/0xb0
+...
+[10136.669628] Call trace:
+[10136.669634] lima_devfreq_record_idle+0xa0/0xb0
+[10136.669646] lima_sched_pipe_task_done+0x5c/0xb0
+[10136.669656] lima_gp_irq_handler+0xa8/0x120
+[10136.669666] __handle_irq_event_percpu+0x48/0x160
+[10136.669679] handle_irq_event+0x4c/0xc0
+
+We can prevent that race condition entirely by masking the irqs at the
+beginning of the timeout handler, at which point we give up on waiting
+for that job entirely.
+The irqs will be enabled again at the next hard reset which is already
+done as a recovery by the timeout handler.

+trace_drop_common() also disables interrupts, but this is a minor issue

+
+This device sometimes doesn't send touch release signals when moving
+from >=4 fingers to <4 fingers. Using MT_QUIRK_NOT_SEEN_MEANS_UP instead
+of MT_QUIRK_ALWAYS_VALID makes sure that no touches become stuck.
+
+MT_QUIRK_FORCE_MULTI_INPUT is not necessary for this device, but does no
+harm.

+Subject: MIPS: Octeon: Add PCIe link status check
+
+From: Songyang Li <leesongyang@outlook.com>
+
+[ Upstream commit 29b83a64df3b42c88c0338696feb6fdcd7f1f3b7 ]
+
+The standard PCIe configuration read-write interface is used to
+access the configuration space of the peripheral PCIe devices
+of the mips processor after the PCIe link surprise down, it can
+generate kernel panic caused by "Data bus error". So it is
+necessary to add PCIe link status check for system protection.
+When the PCIe link is down or in training, assigning a value
+of 0 to the configuration address can prevent read-write behavior
+to the configuration space of peripheral PCIe devices, thereby
+preventing kernel panic.

+From: Breno Leitao <leitao@debian.org>
+
+[ Upstream commit c2e6a872bde9912f1a7579639c5ca3adf1003916 ]
+
+KCSAN detected a race condition in netpoll:
+
+ BUG: KCSAN: data-race in net_rx_action / netpoll_send_skb
+ write (marked) to 0xffff8881164168b0 of 4 bytes by interrupt on cpu 10:
+ net_rx_action (./include/linux/netpoll.h:90 net/core/dev.c:6712 net/core/dev.c:6822)
+<snip>
+ read to 0xffff8881164168b0 of 4 bytes by task 1 on cpu 2:
+ netpoll_send_skb (net/core/netpoll.c:319 net/core/netpoll.c:345 net/core/netpoll.c:393)
+ netpoll_send_udp (net/core/netpoll.c:?)
+<snip>
+ value changed: 0x0000000a -> 0xffffffff
+
+This happens because netpoll_owner_active() needs to check if the
+current CPU is the owner of the lock, touching napi->poll_owner
+non atomically. The ->poll_owner field contains the current CPU holding
+the lock.
+
+Use an atomic read to check if the poll owner is the current CPU.

+Subject: PCI/PM: Avoid D3cold for HP Pavilion 17 PC/1972 PCIe Ports
+
+From: Mario Limonciello <mario.limonciello@amd.com>
+
+[ Upstream commit 256df20c590bf0e4d63ac69330cf23faddac3e08 ]
+
+Hewlett-Packard HP Pavilion 17 Notebook PC/1972 is an Intel Ivy Bridge
+system with a muxless AMD Radeon dGPU. Attempting to use the dGPU fails
+with the following sequence:
+
+ ACPI Error: Aborting method \AMD3._ON due to previous error (AE_AML_LOOP_TIMEOUT) (20230628/psparse-529)
+ radeon 0000:01:00.0: not ready 1023ms after resume; waiting
+ radeon 0000:01:00.0: not ready 2047ms after resume; waiting
+ radeon 0000:01:00.0: not ready 4095ms after resume; waiting
+ radeon 0000:01:00.0: not ready 8191ms after resume; waiting
+ radeon 0000:01:00.0: not ready 16383ms after resume; waiting
+ radeon 0000:01:00.0: not ready 32767ms after resume; waiting
+ radeon 0000:01:00.0: not ready 65535ms after resume; giving up
+ radeon 0000:01:00.0: Unable to change power state from D3cold to D0, device inaccessible
+
+The issue is that the Root Port the dGPU is connected to can't handle the
+transition from D3cold to D0 so the dGPU can't properly exit runtime PM.
+
+The existing logic in pci_bridge_d3_possible() checks for systems that are
+newer than 2015 to decide that D3 is safe. This would nominally work for
+an Ivy Bridge system (which was discontinued in 2015), but this system
+appears to have continued to receive BIOS updates until 2017 and so this
+existing logic doesn't appropriately capture it.
+
+Add the system to bridge_d3_blacklist to prevent D3cold from being used.

+Subject: powerpc/io: Avoid clang null pointer arithmetic warnings
+
+From: Michael Ellerman <mpe@ellerman.id.au>
+
+[ Upstream commit 03c0f2c2b2220fc9cf8785cd7b61d3e71e24a366 ]
+
+With -Wextra clang warns about pointer arithmetic using a null pointer.
+When building with CONFIG_PCI=n, that triggers a warning in the IO
+accessors, eg:
+
+ In file included from linux/arch/powerpc/include/asm/io.h:672:
+ linux/arch/powerpc/include/asm/io-defs.h:23:1: warning: performing pointer arithmetic on a null pointer has undefined behavior [-Wnull-pointer-arithmetic]
+ 23 | DEF_PCI_AC_RET(inb, u8, (unsigned long port), (port), pio, port)
+ | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ ...
+ linux/arch/powerpc/include/asm/io.h:591:53: note: expanded from macro '__do_inb'
+ 591 | #define __do_inb(port) readb((PCI_IO_ADDR)_IO_BASE + port);
+ | ~~~~~~~~~~~~~~~~~~~~~ ^
+
+That is because when CONFIG_PCI=n, _IO_BASE is defined as 0.
+
+Although _IO_BASE is defined as plain 0, the cast (PCI_IO_ADDR) converts
+it to void * before the addition with port happens.
+
+Instead the addition can be done first, and then the cast. The resulting
+value will be the same, but avoids the warning, and also avoids void
+pointer arithmetic which is apparently non-standard.

+Subject: powerpc/pseries: Enforce hcall result buffer validity and size
+
+From: Nathan Lynch <nathanl@linux.ibm.com>
+
+[ Upstream commit ff2e185cf73df480ec69675936c4ee75a445c3e4 ]
+
+plpar_hcall(), plpar_hcall9(), and related functions expect callers to
+provide valid result buffers of certain minimum size. Currently this
+is communicated only through comments in the code and the compiler has
+no idea.
+
+For example, if I write a bug like this:
+
+ long retbuf[PLPAR_HCALL_BUFSIZE]; // should be PLPAR_HCALL9_BUFSIZE
+ plpar_hcall9(H_ALLOCATE_VAS_WINDOW, retbuf, ...);
+
+This compiles with no diagnostics emitted, but likely results in stack
+corruption at runtime when plpar_hcall9() stores results past the end
+of the array. (To be clear this is a contrived example and I have not
+found a real instance yet.)
+
+To make this class of error less likely, we can use explicitly-sized
+array parameters instead of pointers in the declarations for the hcall
+APIs. When compiled with -Warray-bounds[1], the code above now
+provokes a diagnostic like this:
+
+error: array argument is too small;
+is of size 32, callee requires at least 72 [-Werror,-Warray-bounds]
+ 60 | plpar_hcall9(H_ALLOCATE_VAS_WINDOW, retbuf,
+ | ^ ~~~~~~
+
+[1] Enabled for LLVM builds but not GCC for now. See commit
+ 0da6e5fd6c37 ("gcc: disable '-Warray-bounds' for gcc-13 too") and
+ related changes.

+Subject: scsi: qedi: Fix crash while reading debugfs attribute
+
+From: Manish Rangankar <mrangankar@marvell.com>
+
+[ Upstream commit 28027ec8e32ecbadcd67623edb290dad61e735b5 ]
+
+The qedi_dbg_do_not_recover_cmd_read() function invokes sprintf() directly
+on a __user pointer, which results into the crash.
+
+To fix this issue, use a small local stack buffer for sprintf() and then
+call simple_read_from_buffer(), which in turns make the copy_to_user()
+call.

+Subject: selftests/bpf: Fix flaky test btf_map_in_map/lookup_update
+
+From: Yonghong Song <yonghong.song@linux.dev>
+
+[ Upstream commit 14bb1e8c8d4ad5d9d2febb7d19c70a3cf536e1e5 ]
+
+Recently, I frequently hit the following test failure:
+
+ [root@arch-fb-vm1 bpf]# ./test_progs -n 33/1
+ test_lookup_update:PASS:skel_open 0 nsec
+ [...]
+ test_lookup_update:PASS:sync_rcu 0 nsec
+ test_lookup_update:FAIL:map1_leak inner_map1 leaked!
+ #33/1 btf_map_in_map/lookup_update:FAIL
+ #33 btf_map_in_map:FAIL
+
+In the test, after map is closed and then after two rcu grace periods,
+it is assumed that map_id is not available to user space.
+
+But the above assumption cannot be guaranteed. After zero or one
+or two rcu grace periods in different siturations, the actual
+freeing-map-work is put into a workqueue. Later on, when the work
+is dequeued, the map will be actually freed.
+See bpf_map_put() in kernel/bpf/syscall.c.
+
+By using workqueue, there is no ganrantee that map will be actually
+freed after a couple of rcu grace periods. This patch removed
+such map leak detection and then the test can pass consistently.

+Subject: selftests/bpf: Prevent client connect before server bind in
+ test_tc_tunnel.sh
+
+From: Alessandro Carminati (Red Hat) <alessandro.carminati@gmail.com>
+
+[ Upstream commit f803bcf9208a2540acb4c32bdc3616673169f490 ]
+
+In some systems, the netcat server can incur in delay to start listening.
+When this happens, the test can randomly fail in various points.
+This is an example error message:
+
+ # ip gre none gso
+ # encap 192.168.1.1 to 192.168.1.2, type gre, mac none len 2000
+ # test basic connectivity
+ # Ncat: Connection refused.
+
+The issue stems from a race condition between the netcat client and server.
+The test author had addressed this problem by implementing a sleep, which
+I have removed in this patch.
+This patch introduces a function capable of sleeping for up to two seconds.
+However, it can terminate the waiting period early if the port is reported
+to be listening.

+Subject: udf: udftime: prevent overflow in udf_disk_stamp_to_time()
+
+From: Roman Smirnov <r.smirnov@omp.ru>
+
+[ Upstream commit 3b84adf460381169c085e4bc09e7b57e9e16db0a ]
+
+An overflow can occur in a situation where src.centiseconds
+takes the value of 255. This situation is unlikely, but there
+is no validation check anywere in the code.
+
+Found by Linux Verification Center (linuxtesting.org) with Svace.

+From: Alex Henrie <alexhenrie24@gmail.com>
+
+[ Upstream commit 3295f1b866bfbcabd625511968e8a5c541f9ab32 ]
+
+The incompatible device in my possession has a sticker that says
+"F5U002 Rev 2" and "P80453-B", and lsusb identifies it as
+"050d:0002 Belkin Components IEEE-1284 Controller". There is a bug
+report from 2007 from Michael Trausch who was seeing the exact same
+errors that I saw in 2024 trying to use this cable.

+Subject: wifi: ath9k: work around memset overflow warning
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Arnd Bergmann <arnd@arndb.de>
+
+[ Upstream commit 61752ac69b69ed2e04444d090f6917c77ab36d42 ]
+
+gcc-9 and some other older versions produce a false-positive warning
+for zeroing two fields
+
+In file included from include/linux/string.h:369,
+ from drivers/net/wireless/ath/ath9k/main.c:18:
+In function 'fortify_memset_chk',
+ inlined from 'ath9k_ps_wakeup' at drivers/net/wireless/ath/ath9k/main.c:140:3:
+include/linux/fortify-string.h:462:25: error: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror=attribute-warning]
+ 462 | __write_overflow_field(p_size_field, size);
+ | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Using a struct_group seems to reliably avoid the warning and
+not make the code much uglier. The combined memset() should even
+save a couple of cpu cycles.
