+Subject: ACPI: disable -Wstringop-truncation
+
+From: Arnd Bergmann <arnd@arndb.de>
+
+[ Upstream commit a3403d304708f60565582d60af4316289d0316a0 ]
+
+gcc -Wstringop-truncation warns about copying a string that results in a
+missing nul termination:
+
+drivers/acpi/acpica/tbfind.c: In function 'acpi_tb_find_table':
+drivers/acpi/acpica/tbfind.c:60:9: error: 'strncpy' specified bound 6 equals destination size [-Werror=stringop-truncation]
+ 60 | strncpy(header.oem_id, oem_id, ACPI_OEM_ID_SIZE);
+ | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+drivers/acpi/acpica/tbfind.c:61:9: error: 'strncpy' specified bound 8 equals destination size [-Werror=stringop-truncation]
+ 61 | strncpy(header.oem_table_id, oem_table_id, ACPI_OEM_TABLE_ID_SIZE);
+ | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The code works as intended, and the warning could be addressed by using
+a memcpy(), but turning the warning off for this file works equally well
+and may be easier to merge.

+
+packet_read_pending() is very expensive, and calling it

+Subject: af_unix: Fix data races in unix_release_sock/unix_stream_sendmsg
+
+From: Breno Leitao <leitao@debian.org>
+
+[ Upstream commit 540bf24fba16b88c1b3b9353927204b4f1074e25 ]
+
+A data-race condition has been identified in af_unix. In one data path,
+the write function unix_release_sock() atomically writes to
+sk->sk_shutdown using WRITE_ONCE. However, on the reader side,
+unix_stream_sendmsg() does not read it atomically. Consequently, this
+issue is causing the following KCSAN splat to occur:

+
+Since commit daa480bde6b3 ("ASoC: soc-core: tidyup for

+
+The codec leaves tie combo jack's sleeve/ring2 to floating status
+default. It would cause electric noise while connecting the active
+speaker jack during boot or shutdown.
+This patch requests a gpio to control the additional jack circuit
+to tie the contacts to the ground or floating.

+
+[ Upstream commit 58300f8d6a48e58d1843199be743f819e2791ea3 ]
+
+The string SND_SOC_DAPM_DIR_OUT is printed in the snd_soc_dapm_path trace

+
+ (((REC->path_dir) == SND_SOC_DAPM_DIR_OUT) ? "->" : "<-")

+User space cannot parse this, as it has no idea what SND_SOC_DAPM_DIR_OUT
+is. Use TRACE_DEFINE_ENUM() to convert it to its value:

+
+So that user space tools, such as perf and trace-cmd, can parse it
+correctly.

+Subject: bpf: Pack struct bpf_fib_lookup
+
+From: Anton Protopopov <aspsk@isovalent.com>
+
+[ Upstream commit f91717007217d975aa975ddabd91ae1a107b9bff ]
+
+The struct bpf_fib_lookup is supposed to be of size 64. A recent commit
+59b418c7063d ("bpf: Add a check for struct bpf_fib_lookup size") added
+a static assertion to check this property so that future changes to the
+structure will not accidentally break this assumption.
+
+As it immediately turned out, on some 32-bit arm systems, when AEABI=n,
+the total size of the structure was equal to 68, see [1]. This happened
+because the bpf_fib_lookup structure contains a union of two 16-bit
+fields:
+
+ union {
+ __u16 tot_len;
+ __u16 mtu_result;
+ };
+
+which was supposed to compile to a 16-bit-aligned 16-bit field. On the
+aforementioned setups it was instead both aligned and padded to 32-bits.
+
+Declare this inner union as __attribute__((packed, aligned(2))) such
+that it always is of size 2 and is aligned to 16 bits.

+cppc_cpufreq_get_rate() and hisi_cppc_cpufreq_get_rate() can be called from

+
+[ Upstream commit f339f3541701d824a0256ad4bf14c26ceb6d79c3 ]
+
+Currently, cpufreq_remove_dev() invokes the ->exit() driver callback
+without holding the policy rwsem which is inconsistent with what
+happens if ->exit() is invoked directly from cpufreq_offline().
+
+It also manipulates the real_cpus mask and removes the CPU device
+symlink without holding the policy rwsem, but cpufreq_offline() holds
+the rwsem around the modifications thereof.
+
+For consistency, modify cpufreq_remove_dev() to hold the policy rwsem
+until the ->exit() callback has been called (or it has been determined
+that it is not necessary to call it).

+Subject: dev_printk: Add and use dev_no_printk()
+
+From: Geert Uytterhoeven <geert+renesas@glider.be>
+
+[ Upstream commit c26ec799042a3888935d59b599f33e41efedf5f8 ]
+
+When printk-indexing is enabled, each dev_printk() invocation emits a
+pi_entry structure. This is even true when the dev_printk() is
+protected by an always-false check, as is typically the case for debug
+messages: while the actual code to print the message is optimized out by
+the compiler, the pi_entry structure is still emitted.
+
+Avoid emitting pi_entry structures for unavailable dev_printk() kernel
+messages by:
+ 1. Introducing a dev_no_printk() helper, mimicked after the existing
+ no_printk() helper, which calls _dev_printk() instead of
+ dev_printk(),
+ 2. Replacing all "if (0) dev_printk(...)" constructs by calls to the
+ new helper.
+
+This reduces the size of an arm64 defconfig kernel with
+CONFIG_PRINTK_INDEX=y by 957 KiB.

+Subject: drivers/virt/acrn: fix PFNMAP PTE checks in acrn_vm_ram_map()
+
+From: David Hildenbrand <david@redhat.com>
+
+[ Upstream commit 3d6586008f7b638f91f3332602592caa8b00b559 ]
+
+Patch series "mm: follow_pte() improvements and acrn follow_pte() fixes".
+
+Patch #1 fixes a bunch of issues I spotted in the acrn driver. It
+compiles, that's all I know. I'll appreciate some review and testing from
+acrn folks.
+
+Patch #2+#3 improve follow_pte(), passing a VMA instead of the MM, adding
+more sanity checks, and improving the documentation. Gave it a quick test
+on x86-64 using VM_PAT that ends up using follow_pte().
+
+This patch (of 3):
+
+We currently miss handling various cases, resulting in a dangerous
+follow_pte() (previously follow_pfn()) usage.
+
+(1) We're not checking PTE write permissions.
+
+Maybe we should simply always require pte_write() like we do for
+pin_user_pages_fast(FOLL_WRITE)? Hard to tell, so let's check for
+ACRN_MEM_ACCESS_WRITE for now.
+
+(2) We're not rejecting refcounted pages.
+
+As we are not using MMU notifiers, messing with refcounted pages is
+dangerous and can result in use-after-free. Let's make sure to reject them.
+
+(3) We are only looking at the first PTE of a bigger range.
+
+We only lookup a single PTE, but memmap->len may span a larger area.
+Let's loop over all involved PTEs and make sure the PFN range is
+actually contiguous. Reject everything else: it couldn't have worked
+either way, and rather made use access PFNs we shouldn't be accessing.

+Subject: drm/amd/display: Fix potential index out of bounds in color
+ transformation function
+
+From: Srinivasan Shanmugam <srinivasan.shanmugam@amd.com>
+
+[ Upstream commit 63ae548f1054a0b71678d0349c7dc9628ddd42ca ]
+
+Fixes index out of bounds issue in the color transformation function.
+The issue could occur when the index 'i' exceeds the number of transfer
+function points (TRANSFER_FUNC_POINTS).
+
+The fix adds a check to ensure 'i' is within bounds before accessing the
+transfer function points. If 'i' is out of bounds, an error message is
+logged and the function returns false to indicate an error.

+Subject: drm/amdkfd: Flush the process wq before creating a kfd_process
+
+From: Lancelot SIX <lancelot.six@amd.com>
+
+[ Upstream commit f5b9053398e70a0c10aa9cb4dd5910ab6bc457c5 ]
+
+There is a race condition when re-creating a kfd_process for a process.
+This has been observed when a process under the debugger executes
+exec(3). In this scenario:
+- The process executes exec.
+ - This will eventually release the process's mm, which will cause the
+ kfd_process object associated with the process to be freed
+ (kfd_process_free_notifier decrements the reference count to the
+ kfd_process to 0). This causes kfd_process_ref_release to enqueue
+ kfd_process_wq_release to the kfd_process_wq.
+- The debugger receives the PTRACE_EVENT_EXEC notification, and tries to
+ re-enable AMDGPU traps (KFD_IOC_DBG_TRAP_ENABLE).
+ - When handling this request, KFD tries to re-create a kfd_process.
+ This eventually calls kfd_create_process and kobject_init_and_add.
+
+At this point the call to kobject_init_and_add can fail because the
+old kfd_process.kobj has not been freed yet by kfd_process_wq_release.
+
+This patch proposes to avoid this race by making sure to drain
+kfd_process_wq before creating a new kfd_process object. This way, we
+know that any cleanup task is done executing when we reach
+kobject_init_and_add.

+From: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
+

+
+The functions mipi_dsi_compression_mode() and
+mipi_dsi_picture_parameter_set() return 0-or-error rather than a buffer
+size. Follow example of other similar MIPI DSI functions and use int
+return type instead of size_t.

+Subject: drm/panel: simple: Add missing Innolux G121X1-L03 format, flags,
+ connector
+
+From: Marek Vasut <marex@denx.de>
+
+[ Upstream commit 11ac72d033b9f577e8ba0c7a41d1c312bb232593 ]
+
+The .bpc = 6 implies .bus_format = MEDIA_BUS_FMT_RGB666_1X7X3_SPWG ,
+add the missing bus_format. Add missing connector type and bus_flags
+as well.
+
+Documentation [1] 1.4 GENERAL SPECIFICATI0NS indicates this panel is
+capable of both RGB 18bit/24bit panel, the current configuration uses
+18bit mode, .bus_format = MEDIA_BUS_FMT_RGB666_1X7X3_SPWG , .bpc = 6.
+
+Support for the 24bit mode would require another entry in panel-simple
+with .bus_format = MEDIA_BUS_FMT_RGB666_1X7X4_SPWG and .bpc = 8, which
+is out of scope of this fix.

+Subject: ecryptfs: Fix buffer size for tag 66 packet
+
+From: Brian Kubisiak <brian@kubisiak.com>
+
+[ Upstream commit 85a6a1aff08ec9f5b929d345d066e2830e8818e5 ]
+
+The 'TAG 66 Packet Format' description is missing the cipher code and
+checksum fields that are packed into the message packet. As a result,
+the buffer allocated for the packet is 3 bytes too small and
+write_tag_66_packet() will write up to 3 bytes past the end of the
+buffer.
+
+Fix this by increasing the size of the allocation so the whole packet
+will always fit in the buffer.
+
+This fixes the below kasan slab-out-of-bounds bug:

+Subject: epoll: be better about file lifetimes
+
+From: Linus Torvalds <torvalds@linux-foundation.org>
+
+[ Upstream commit 4efaa5acf0a1d2b5947f98abb3acf8bfd966422b ]
+
+epoll can call out to vfs_poll() with a file pointer that may race with
+the last 'fput()'. That would make f_count go down to zero, and while
+the ep->mtx locking means that the resulting file pointer tear-down will
+be blocked until the poll returns, it means that f_count is already
+dead, and any use of it won't actually get a reference to the file any
+more: it's dead regardless.
+
+Make sure we have a valid ref on the file pointer before we call down to
+vfs_poll() from the epoll routines.

+Subject: eth: sungem: remove .ndo_poll_controller to avoid deadlocks
+
+From: Jakub Kicinski <kuba@kernel.org>
+
+[ Upstream commit ac0a230f719b02432d8c7eba7615ebd691da86f4 ]
+
+Erhard reports netpoll warnings from sungem:
+
+ netpoll_send_skb_on_dev(): eth0 enabled interrupts in poll (gem_start_xmit+0x0/0x398)
+ WARNING: CPU: 1 PID: 1 at net/core/netpoll.c:370 netpoll_send_skb+0x1fc/0x20c
+
+gem_poll_controller() disables interrupts, which may sleep.
+We can't sleep in netpoll, it has interrupts disabled completely.
+Strangely, gem_poll_controller() doesn't even poll the completions,
+and instead acts as if an interrupt has fired so it just schedules
+NAPI and exits. None of this has been necessary for years, since
+netpoll invokes NAPI directly.

+Subject: ext4: avoid excessive credit estimate in ext4_tmpfile()
+
+From: Jan Kara <jack@suse.cz>
+
+[ Upstream commit 35a1f12f0ca857fee1d7a04ef52cbd5f1f84de13 ]
+
+A user with minimum journal size (1024 blocks these days) complained
+about the following error triggered by generic/697 test in
+ext4_tmpfile():
+
+run fstests generic/697 at 2024-02-28 05:34:46
+JBD2: vfstest wants too many credits credits:260 rsv_credits:0 max:256
+EXT4-fs error (device loop0) in __ext4_new_inode:1083: error 28
+
+Indeed the credit estimate in ext4_tmpfile() is huge.
+EXT4_MAXQUOTAS_INIT_BLOCKS() is 219, then 10 credits from ext4_tmpfile()
+itself and then ext4_xattr_credits_for_new_inode() adds more credits
+needed for security attributes and ACLs. Now the
+EXT4_MAXQUOTAS_INIT_BLOCKS() is in fact unnecessary because we've
+already initialized quotas with dquot_init() shortly before and so
+EXT4_MAXQUOTAS_TRANS_BLOCKS() is enough (which boils down to 3 credits).

+ext4_mb_new_blocks_simple ignores the group before goal, so it will fail

+There is no reason to prohibit sh7760fb from being built as a

+from bool to tristate to allow that and change the FB dependency as

+Subject: firmware: raspberrypi: Use correct device for DMA mappings
+
+From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
+
+[ Upstream commit df518a0ae1b982a4dcf2235464016c0c4576a34d ]
+
+The buffer used to transfer data over the mailbox interface is mapped
+using the client's device. This is incorrect, as the device performing
+the DMA transfer is the mailbox itself. Fix it by using the mailbox
+controller device instead.
+
+This requires including the mailbox_controller.h header to dereference
+the mbox_chan and mbox_controller structures. The header is not meant to
+be included by clients. This could be fixed by extending the client API
+with a function to access the controller's device.

+
+[ Upstream commit 5d9231111966b6c5a65016d58dcbeab91055bc91 ]
+
+Commit 3e11e53041502 tries to suppress dlm_lock() lock conversion errors
+that occur when the lockspace has already been released.
+
+It does that by setting and checking the SDF_SKIP_DLM_UNLOCK flag. This
+conflicts with the intended meaning of the SDF_SKIP_DLM_UNLOCK flag, so
+check whether the lockspace is still allocated instead.
+
+(Given the current DLM API, checking for this kind of error after the
+fact seems easier that than to make sure that the lockspace is still
+allocated before calling dlm_lock(). Changing the DLM API so that users
+maintain the lockspace references themselves would be an option.)

+Subject: ipv6: sr: fix invalid unregister error path
+
+From: Hangbin Liu <liuhangbin@gmail.com>
+
+[ Upstream commit 160e9d2752181fcf18c662e74022d77d3164cd45 ]
+
+The error path of seg6_init() is wrong in case CONFIG_IPV6_SEG6_LWTUNNEL
+is not defined. In that case if seg6_hmac_init() fails, the
+genl_unregister_family() isn't called.
+
+This issue exist since commit 46738b1317e1 ("ipv6: sr: add option to control
+lwtunnel support"), and commit 5559cea2d5aa ("ipv6: sr: fix possible
+use-after-free and null-ptr-deref") replaced unregister_pernet_subsys()
+with genl_unregister_family() in this error path.

+Subject: jffs2: prevent xattr node from overflowing the eraseblock
+
+From: Ilya Denisyev <dev@elkcl.ru>
+
+[ Upstream commit c6854e5a267c28300ff045480b5a7ee7f6f1d913 ]
+
+Add a check to make sure that the requested xattr node size is no larger
+than the eraseblock minus the cleanmarker.
+
+Unlike the usual inode nodes, the xattr nodes aren't split into parts
+and spread across multiple eraseblocks, which means that a xattr node
+must not occupy more than one eraseblock. If the requested xattr value is
+too large, the xattr node can spill onto the next eraseblock, overwriting
+the nodes and causing errors such as:
+
+jffs2: argh. node added in wrong place at 0x0000b050(2)
+jffs2: nextblock 0x0000a000, expected at 0000b00c
+jffs2: error: (823) do_verify_xattr_datum: node CRC failed at 0x01e050,
+read=0xfc892c93, calc=0x000000
+jffs2: notice: (823) jffs2_get_inode_nodes: Node header CRC failed
+at 0x01e00c. {848f,2fc4,0fef511f,59a3d171}
+jffs2: Node at 0x0000000c with length 0x00001044 would run over the
+end of the erase block

+jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found
+at 0x00000010: 0x1044 instead
+
+This breaks the filesystem and can lead to KASAN crashes such as:

+Subject: m68k: Fix spinlock race in kernel thread creation
+
+From: Michael Schmitz <schmitzmic@gmail.com>
+
+[ Upstream commit da89ce46f02470ef08f0f580755d14d547da59ed ]
+
+Context switching does take care to retain the correct lock owner across
+the switch from 'prev' to 'next' tasks. This does rely on interrupts
+remaining disabled for the entire duration of the switch.
+
+This condition is guaranteed for normal process creation and context
+switching between already running processes, because both 'prev' and
+'next' already have interrupts disabled in their saved copies of the
+status register.
+
+The situation is different for newly created kernel threads. The status
+register is set to PS_S in copy_thread(), which does leave the IPL at 0.
+Upon restoring the 'next' thread's status register in switch_to() aka
+resume(), interrupts then become enabled prematurely. resume() then
+returns via ret_from_kernel_thread() and schedule_tail() where run queue
+lock is released (see finish_task_switch() and finish_lock_switch()).
+
+A timer interrupt calling scheduler_tick() before the lock is released
+in finish_task_switch() will find the lock already taken, with the
+current task as lock owner. This causes a spinlock recursion warning as
+reported by Guenter Roeck.
+
+As far as I can ascertain, this race has been opened in commit
+533e6903bea0 ("m68k: split ret_from_fork(), simplify kernel_thread()")
+but I haven't done a detailed study of kernel history so it may well
+predate that commit.
+
+Interrupts cannot be disabled in the saved status register copy for
+kernel threads (init will complain about interrupts disabled when
+finally starting user space). Disable interrupts temporarily when
+switching the tasks' register sets in resume().
+
+Note that a simple oriw 0x700,%sr after restoring sr is not enough here
+- this leaves enough of a race for the 'spinlock recursion' warning to
+still be observed.
+
+Tested on ARAnyM and qemu (Quadra 800 emulation).

+Subject: m68k: mac: Fix reboot hang on Mac IIci
+
+From: Finn Thain <fthain@linux-m68k.org>
+
+[ Upstream commit 265a3b322df9a973ff1fc63da70af456ab6ae1d6 ]
+
+Calling mac_reset() on a Mac IIci does reset the system, but what
+follows is a POST failure that requires a manual reset to resolve.
+Avoid that by using the 68030 asm implementation instead of the C
+implementation.
+
+Apparently the SE/30 has a similar problem as it has used the asm
+implementation since before git. This patch extends that solution to
+other systems with a similar ROM.
+
+After this patch, the only systems still using the C implementation are
+68040 systems where adb_type is either MAC_ADB_IOP or MAC_ADB_II. This
+implies a 1 MiB Quadra ROM.
+
+This now includes the Quadra 900/950, which previously fell through to
+the "should never get here" catch-all.

+ // j never change
+
+Root cause is that commit 301867b1c168 ("md/raid10: check
+slab-out-of-bounds in md_bitmap_get_counter") return early from
+md_bitmap_get_counter(), without setting returned blocks.
+
+Fix this problem by always set returned blocks from
+md_bitmap_get_counter"(), as it used to be.
+
+Noted that this patch just fix the softlockup problem in kernel, the
+case that bitmap size doesn't match array size still need to be fixed.

+Subject: media: atomisp: ssh_css: Fix a null-pointer dereference in
+ load_video_binaries
+
+From: Zhipeng Lu <alexious@zju.edu.cn>
+
+[ Upstream commit 3b621e9e9e148c0928ab109ac3d4b81487469acb ]
+
+The allocation failure of mycs->yuv_scaler_binary in load_video_binaries()
+is followed with a dereference of mycs->yuv_scaler_binary after the
+following call chain:
+
+sh_css_pipe_load_binaries()
+ |-> load_video_binaries(mycs->yuv_scaler_binary == NULL)
+ |
+ |-> sh_css_pipe_unload_binaries()
+ |-> unload_video_binaries()
+
+In unload_video_binaries(), it calls to ia_css_binary_unload with argument
+&pipe->pipe_settings.video.yuv_scaler_binary[i], which refers to the
+same memory slot as mycs->yuv_scaler_binary. Thus, a null-pointer
+dereference is triggered.

+The original .txt bindings had the OV2680 power supply names correct,

+Subject: mm/slub, kunit: Use inverted data to corrupt kmem cache
+
+From: Guenter Roeck <linux@roeck-us.net>
+
+[ Upstream commit b1080c667b3b2c8c38a7fa83ca5567124887abae ]
+
+Two failure patterns are seen randomly when running slub_kunit tests with
+CONFIG_SLAB_FREELIST_RANDOM and CONFIG_SLAB_FREELIST_HARDENED enabled.
+
+Pattern 1:
+ # test_clobber_zone: pass:1 fail:0 skip:0 total:1
+ ok 1 test_clobber_zone
+ # test_next_pointer: EXPECTATION FAILED at lib/slub_kunit.c:72
+ Expected 3 == slab_errors, but
+ slab_errors == 0 (0x0)
+ # test_next_pointer: EXPECTATION FAILED at lib/slub_kunit.c:84
+ Expected 2 == slab_errors, but
+ slab_errors == 0 (0x0)
+ # test_next_pointer: pass:0 fail:1 skip:0 total:1
+ not ok 2 test_next_pointer
+
+In this case, test_next_pointer() overwrites p[s->offset], but the data
+at p[s->offset] is already 0x12.
+
+Pattern 2:
+ ok 1 test_clobber_zone
+ # test_next_pointer: EXPECTATION FAILED at lib/slub_kunit.c:72
+ Expected 3 == slab_errors, but
+ slab_errors == 2 (0x2)
+ # test_next_pointer: pass:0 fail:1 skip:0 total:1
+ not ok 2 test_next_pointer
+
+In this case, p[s->offset] has a value other than 0x12, but one of the
+expected failures is nevertheless missing.
+
+Invert data instead of writing a fixed value to corrupt the cache data
+structures to fix the problem.

+Subject: mptcp: SO_KEEPALIVE: fix getsockopt support
+
+From: Matthieu Baerts (NGI0) <matttbe@kernel.org>
+
+[ Upstream commit a65198136eaa15b74ee0abf73f12ef83d469a334 ]
+
+SO_KEEPALIVE support has to be set on each subflow: on each TCP socket,
+where sk_prot->keepalive is defined. Technically, nothing has to be done
+on the MPTCP socket. That's why mptcp_sol_socket_sync_intval() was
+called instead of mptcp_sol_socket_intval().
+
+Except that when nothing is done on the MPTCP socket, the
+getsockopt(SO_KEEPALIVE), handled in net/core/sock.c:sk_getsockopt(),
+will not know if SO_KEEPALIVE has been set on the different subflows or
+not.
+
+The fix is simple: simply call mptcp_sol_socket_intval() which will end
+up calling net/core/sock.c:sk_setsockopt() where the SOCK_KEEPOPEN flag
+will be set, the one used in sk_getsockopt().
+
+So now, getsockopt(SO_KEEPALIVE) on an MPTCP socket will return the same
+value as the one previously set with setsockopt(SO_KEEPALIVE).

+
+From: Maxim Korotkov <korotkov.maxim.s@gmail.com>
+
+[ Upstream commit 6819db94e1cd3ce24a432f3616cd563ed0c4eaba ]
+
+The function hynix_nand_rr_init() should probably return an error code.
+Judging by the usage, it seems that the return code is passed up
+the call stack.
+Right now, it always returns 0 and the function hynix_nand_cleanup()
+in hynix_nand_init() has never been called.

+Subject: net: dsa: mv88e6xxx: Add support for model-specific pre- and
+ post-reset handlers
+
+From: Matthias Schiffer <matthias.schiffer@ew.tq-group.com>
+
+[ Upstream commit 0fdd27b9d6d7c60bd319d3497ad797934bab13cb ]
+
+Instead of calling mv88e6xxx_g2_eeprom_wait() directly from
+mv88e6xxx_hardware_reset(), add configurable pre- and post-reset hard
+reset handlers. Initially, the handlers are set to
+mv88e6xxx_g2_eeprom_wait() for all families that have get/set_eeprom()
+to match the existing behavior. No functional change intended (except
+for additional error messages on failure).

+Subject: net: dsa: mv88e6xxx: Avoid EEPROM timeout without EEPROM on
+ 88E6250-family switches
+
+From: Matthias Schiffer <matthias.schiffer@ew.tq-group.com>
+
+[ Upstream commit e44894e2aa4eb311ceda134de8b6f51ff979211b ]
+
+88E6250-family switches have the quirk that the EEPROM Running flag can
+get stuck at 1 when no EEPROM is connected, causing
+mv88e6xxx_g2_eeprom_wait() to time out. We still want to wait for the
+EEPROM however, to avoid interrupting a transfer and leaving the EEPROM
+in an invalid state.
+
+The condition to wait for recommended by the hardware spec is the EEInt
+flag, however this flag is cleared on read, so before the hardware reset,
+is may have been cleared already even though the EEPROM has been read
+successfully.
+
+For this reason, we revive the mv88e6xxx_g1_wait_eeprom_done() function
+that was removed in commit 6ccf50d4d474
+("net: dsa: mv88e6xxx: Avoid EEPROM timeout when EEPROM is absent") in a
+slightly refactored form, and introduce a new
+mv88e6xxx_g1_wait_eeprom_done_prereset() that additionally handles this
+case by triggering another EEPROM reload that can be waited on.
+
+On other switch models without this quirk, mv88e6xxx_g2_eeprom_wait() is
+kept, as it avoids the additional reload.
+

+Subject: net: give more chances to rcu in netdev_wait_allrefs_any()
+
+From: Eric Dumazet <edumazet@google.com>
+
+[ Upstream commit cd42ba1c8ac9deb9032add6adf491110e7442040 ]
+
+This came while reviewing commit c4e86b4363ac ("net: add two more
+call_rcu_hurry()").
+
+Paolo asked if adding one synchronize_rcu() would help.
+
+While synchronize_rcu() does not help, making sure to call
+rcu_barrier() before msleep(wait) is definitely helping
+to make sure lazy call_rcu() are completed.
+
+Instead of waiting ~100 seconds in my tests, the ref_tracker
+splats occurs one time only, and netdev_wait_allrefs_any()
+latency is reduced to the strict minimum.
+
+Ideally we should audit our call_rcu() users to make sure
+no refcount (or cascading call_rcu()) is held too long,
+because rcu_barrier() is quite expensive.

+Subject: net: ipv6: fix wrong start position when receive hop-by-hop fragment
+
+From: gaoxingwang <gaoxingwang1@huawei.com>
+
+[ Upstream commit 1cd354fe1e4864eeaff62f66ee513080ec946f20 ]
+
+In IPv6, ipv6_rcv_core will parse the hop-by-hop type extension header and increase skb->transport_header by one extension header length.
+But if there are more other extension headers like fragment header at this time, the skb->transport_header points to the second extension header,
+not the transport layer header or the first extension header.
+
+This will result in the start and nexthdrp variable not pointing to the same position in ipv6frag_thdr_trunced,
+and ipv6_skip_exthdr returning incorrect offset and frag_off.Sometimes,the length of the last sharded packet is smaller than the calculated incorrect offset, resulting in packet loss.
+We can use network header to offset and calculate the correct position to solve this problem.

+Subject: net: openvswitch: fix overwriting ct original tuple for ICMPv6
+
+From: Ilya Maximets <i.maximets@ovn.org>
+
+[ Upstream commit 7c988176b6c16c516474f6fceebe0f055af5eb56 ]
+
+OVS_PACKET_CMD_EXECUTE has 3 main attributes:
+ - OVS_PACKET_ATTR_KEY - Packet metadata in a netlink format.
+ - OVS_PACKET_ATTR_PACKET - Binary packet content.
+ - OVS_PACKET_ATTR_ACTIONS - Actions to execute on the packet.
+
+OVS_PACKET_ATTR_KEY is parsed first to populate sw_flow_key structure
+with the metadata like conntrack state, input port, recirculation id,
+etc. Then the packet itself gets parsed to populate the rest of the
+keys from the packet headers.
+
+Whenever the packet parsing code starts parsing the ICMPv6 header, it
+first zeroes out fields in the key corresponding to Neighbor Discovery
+information even if it is not an ND packet.
+
+It is an 'ipv6.nd' field. However, the 'ipv6' is a union that shares
+the space between 'nd' and 'ct_orig' that holds the original tuple
+conntrack metadata parsed from the OVS_PACKET_ATTR_KEY.
+
+ND packets should not normally have conntrack state, so it's fine to
+share the space, but normal ICMPv6 Echo packets or maybe other types of
+ICMPv6 can have the state attached and it should not be overwritten.
+
+The issue results in all but the last 4 bytes of the destination
+address being wiped from the original conntrack tuple leading to
+incorrect packet matching and potentially executing wrong actions
+in case this packet recirculates within the datapath or goes back
+to userspace.
+
+ND fields should not be accessed in non-ND packets, so not clearing
+them should be fine. Executing memset() only for actual ND packets to
+avoid the issue.
+
+Initializing the whole thing before parsing is needed because ND packet
+may not contain all the options.
+
+The issue only affects the OVS_PACKET_CMD_EXECUTE path and doesn't
+affect packets entering OVS datapath from network interfaces, because
+in this case CT metadata is populated from skb after the packet is
+already parsed.
+
+Fixes: 9dd7f8907c37 ("openvswitch: Add original direction conntrack tuple to sw_flow_key.")

+Subject: net: qrtr: ns: Fix module refcnt
+
+From: Chris Lew <quic_clew@quicinc.com>
+
+[ Upstream commit fd76e5ccc48f9f54eb44909dd7c0b924005f1582 ]
+
+The qrtr protocol core logic and the qrtr nameservice are combined into
+a single module. Neither the core logic or nameservice provide much
+functionality by themselves; combining the two into a single module also
+prevents any possible issues that may stem from client modules loading
+inbetween qrtr and the ns.
+
+Creating a socket takes two references to the module that owns the
+socket protocol. Since the ns needs to create the control socket, this
+creates a scenario where there are always two references to the qrtr
+module. This prevents the execution of 'rmmod' for qrtr.
+
+To resolve this, forcefully put the module refcount for the socket
+opened by the nameservice.
+
+Fixes: a365023a76f2 ("net: qrtr: combine nameservice into main module")

+Subject: net: remove duplicate reuseport_lookup functions
+
+From: Lorenz Bauer <lmb@isovalent.com>
+
+[ Upstream commit 0f495f7617229772403e683033abc473f0f0553c ]
+
+There are currently four copies of reuseport_lookup: one each for
+(TCP, UDP)x(IPv4, IPv6). This forces us to duplicate all callers of
+those functions as well. This is already the case for sk_lookup
+helpers (inet,inet6,udp4,udp6)_lookup_run_bpf.
+
+There are two differences between the reuseport_lookup helpers:
+
+1. They call different hash functions depending on protocol
+2. UDP reuseport_lookup checks that sk_state != TCP_ESTABLISHED
+
+Move the check for sk_state into the caller and use the INDIRECT_CALL
+infrastructure to cut down the helpers to one per IP version.

+Subject: net: usb: smsc95xx: stop lying about skb->truesize
+
+From: Eric Dumazet <edumazet@google.com>
+
+[ Upstream commit d50729f1d60bca822ef6d9c1a5fb28d486bd7593 ]
+
+Some usb drivers try to set small skb->truesize and break
+core networking stacks.
+
+In this patch, I removed one of the skb->truesize override.
+
+I also replaced one skb_clone() by an allocation of a fresh
+and small skb, to get minimally sized skbs, like we did
+in commit 1e2c61172342 ("net: cdc_ncm: reduce skb truesize
+in rx path") and 4ce62d5b2f7a ("net: usb: ax88179_178a:
+stop lying about skb->truesize")
+
+v3: also fix a sparse error ( https://lore.kernel.org/oe-kbuild-all/202405091310.KvncIecx-lkp@intel.com/ )
+v2: leave the skb_trim() game because smsc95xx_rx_csum_offload()
+ needs the csum part. (Jakub)
+ While we are it, use get_unaligned() in smsc95xx_rx_csum_offload().

+Subject: nvme: find numa distance only if controller has valid numa id
+
+From: Nilay Shroff <nilay@linux.ibm.com>
+
+[ Upstream commit 863fe60ed27f2c85172654a63c5b827e72c8b2e6 ]
+
+On system where native nvme multipath is configured and iopolicy
+is set to numa but the nvme controller numa node id is undefined
+or -1 (NUMA_NO_NODE) then avoid calculating node distance for
+finding optimal io path. In such case we may access numa distance
+table with invalid index and that may potentially refer to incorrect
+memory. So this patch ensures that if the nvme controller numa node
+id is -1 then instead of calculating node distance for finding optimal
+io path, we set the numa node distance of such controller to default 10
+(LOCAL_DISTANCE).

+Multiple WMI events can be received concurrently, so multiple instances

+Subject: printk: Let no_printk() use _printk()
+
+From: Geert Uytterhoeven <geert+renesas@glider.be>
+
+[ Upstream commit 8522f6b760ca588928eede740d5d69dd1e936b49 ]
+
+When printk-indexing is enabled, each printk() invocation emits a
+pi_entry structure, containing the format string and other information
+related to its location in the kernel sources. This is even true for
+no_printk(): while the actual code to print the message is optimized out
+by the compiler due to the always-false check, the pi_entry structure is
+still emitted.
+
+As the main purpose of no_printk() is to provide a helper to maintain
+printf()-style format checking when debugging is disabled, this leads to
+the inclusion in the index of lots of printk formats that cannot be
+emitted by the current kernel.
+
+Fix this by switching no_printk() from printk() to _printk().
+
+This reduces the size of an arm64 defconfig kernel with
+CONFIG_PRINTK_INDEX=y by 576 KiB.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+
+[ Upstream commit e13cec3617c6ace4fc389b60d2a7d5b305b62683 ]
+
+The .remove() callback for a platform driver returns an int which makes
+many driver authors wrongly assume it's possible to do error handling by
+returning an error code. However the value returned is (mostly) ignored
+and this typically results in resource leaks. To improve here there is a
+quest to make the remove callback return void. In the first step of this
+quest all drivers are converted to .remove_new() which already returns
+void.
+
+Trivially convert this driver from always returning zero in the remove
+callback to the void returning variant.

+
+[ Upstream commit 5bb0b194aeee5d5da6881232f4e9989b35957c25 ]
+
+Instead of of_clk_get_by_name() use devm_clk_get_prepared() which has
+several advantages:
+
+ - Combines getting the clock and a call to clk_prepare(). The latter
+ can be dropped from sti_pwm_probe() accordingly.
+ - Cares for calling clk_put() which is missing in both probe's error
+ path and the remove function.
+ - Cares for calling clk_unprepare() which can be dropped from the error
+ paths and the remove function. (Note that not all error path got this
+ right.)
+
+With additionally using devm_pwmchip_add() instead of pwmchip_add() the
+remove callback can be dropped completely. With it the last user of
+platform_get_drvdata() goes away and so platform_set_drvdata() can be
+dropped from the probe function, too.

+Too much print may lead to a panic in kernel. Change ibdev_err() to
+ibdev_err_ratelimited(), and change the printing level of cqe dump
+to debug level.

+
+[ Upstream commit 7ab681ddedd4b6dd2b047c74af95221c5f827e1d ]
+
+The regulator IRQ helper requires caller to provide pointer to IRQ name
+which is kept in memory by caller. All other data passed to the helper
+in the regulator_irq_desc structure is copied. This can cause some
+confusion and unnecessary complexity.
+
+Make the regulator_irq_helper() to copy also the provided IRQ name
+information so caller can discard the name after the call to
+regulator_irq_helper() completes.

+Subject: s390/bpf: Emit a barrier for BPF_FETCH instructions
+
+From: Ilya Leoshkevich <iii@linux.ibm.com>
+
+[ Upstream commit 68378982f0b21de02ac3c6a11e2420badefcb4bc ]
+
+BPF_ATOMIC_OP() macro documentation states that "BPF_ADD | BPF_FETCH"
+should be the same as atomic_fetch_add(), which is currently not the
+case on s390x: the serialization instruction "bcr 14,0" is missing.
+This applies to "and", "or" and "xor" variants too.
+
+s390x is allowed to reorder stores with subsequent fetches from
+different addresses, so code relying on BPF_FETCH acting as a barrier,
+for example:
+
+ stw [%r0], 1
+ afadd [%r1], %r2
+ ldxw %r3, [%r4]
+
+may be broken. Fix it by emitting "bcr 14,0".
+
+Note that a separate serialization instruction is not needed for
+BPF_XCHG and BPF_CMPXCHG, because COMPARE AND SWAP performs
+serialization itself.

+Subject: sched/core: Fix incorrect initialization of the 'burst' parameter in
+ cpu_max_write()
+
+From: Cheng Yu <serein.chengyu@huawei.com>
+
+[ Upstream commit 49217ea147df7647cb89161b805c797487783fc0 ]
+
+In the cgroup v2 CPU subsystem, assuming we have a
+cgroup named 'test', and we set cpu.max and cpu.max.burst:
+
+ # echo 1000000 > /sys/fs/cgroup/test/cpu.max
+ # echo 1000000 > /sys/fs/cgroup/test/cpu.max.burst
+
+then we check cpu.max and cpu.max.burst:
+
+ # cat /sys/fs/cgroup/test/cpu.max
+ 1000000 100000
+ # cat /sys/fs/cgroup/test/cpu.max.burst
+ 1000000
+
+Next we set cpu.max again and check cpu.max and
+cpu.max.burst:
+
+ # echo 2000000 > /sys/fs/cgroup/test/cpu.max
+ # cat /sys/fs/cgroup/test/cpu.max
+ 2000000 100000
+
+ # cat /sys/fs/cgroup/test/cpu.max.burst
+ 1000
+
+... we find that the cpu.max.burst value changed unexpectedly.
+
+In cpu_max_write(), the unit of the burst value returned
+by tg_get_cfs_burst() is microseconds, while in cpu_max_write(),
+the burst unit used for calculation should be nanoseconds,
+which leads to the bug.
+
+To fix it, get the burst value directly from tg->cfs_bandwidth.burst.

+Subject: sched/fair: Add EAS checks before updating root_domain::overutilized
+
+From: Shrikanth Hegde <sshegde@linux.ibm.com>
+
+[ Upstream commit be3a51e68f2f1b17250ce40d8872c7645b7a2991 ]
+
+root_domain::overutilized is only used for EAS(energy aware scheduler)
+to decide whether to do load balance or not. It is not used if EAS
+not possible.
+
+Currently enqueue_task_fair and task_tick_fair accesses, sometime updates
+this field. In update_sd_lb_stats it is updated often. This causes cache
+contention due to true sharing and burns a lot of cycles. ::overload and
+::overutilized are part of the same cacheline. Updating it often invalidates
+the cacheline. That causes access to ::overload to slow down due to
+false sharing. Hence add EAS check before accessing/updating this field.
+EAS check is optimized at compile time or it is a static branch.
+Hence it shouldn't cost much.
+
+With the patch, both enqueue_task_fair and newidle_balance don't show
+up as hot routines in perf profile.
+
+ 6.8-rc4:
+ 7.18% swapper [kernel.vmlinux] [k] enqueue_task_fair
+ 6.78% s [kernel.vmlinux] [k] newidle_balance
+
+ +patch:
+ 0.14% swapper [kernel.vmlinux] [k] enqueue_task_fair
+ 0.00% swapper [kernel.vmlinux] [k] newidle_balance
+
+While at it: trace_sched_overutilized_tp expect that second argument to
+be bool. So do a int to bool conversion for that.

+Subject: scsi: libsas: Fix the failure of adding phy with zero-address to port
+
+From: Xingui Yang <yangxingui@huawei.com>
+
+[ Upstream commit 06036a0a5db34642c5dbe22021a767141f010b7a ]
+
+As of commit 7d1d86518118 ("[SCSI] libsas: fix false positive 'device
+attached' conditions"), reset the phy->entacted_sas_addr address to a
+zero-address when the link rate is less than 1.5G.
+
+Currently we find that when a new device is attached, and the link rate is
+less than 1.5G, but the device type is not NO_DEVICE, for example: the link
+rate is SAS_PHY_RESET_IN_PROGRESS and the device type is stp. After setting
+the phy->entacted_sas_addr address to the zero address, the port will
+continue to be created for the phy with the zero-address, and other phys
+with the zero-address will be tried to be added to the new port:
+
+[562240.051197] sas: ex 500e004aaaaaaa1f phy19:U:0 attached: 0000000000000000 (no device)
+// phy19 is deleted but still on the parent port's phy_list
+[562240.062536] sas: ex 500e004aaaaaaa1f phy0 new device attached
+[562240.062616] sas: ex 500e004aaaaaaa1f phy00:U:5 attached: 0000000000000000 (stp)
+[562240.062680] port-7:7:0: trying to add phy phy-7:7:19 fails: it's already part of another port
+
+Therefore, it should be the same as sas_get_phy_attached_dev(). Only when
+device_type is SAS_PHY_UNUSED, sas_address is set to the 0 address.

+
+From: Bui Quang Minh <minhquangbui99@gmail.com>
+
+[ Upstream commit d0184a375ee797eb657d74861ba0935b6e405c62 ]
+
+Currently, we allocate a count-sized kernel buffer and copy count from
+userspace to that buffer. Later, we use kstrtouint on this buffer but we
+don't ensure that the string is terminated inside the buffer, this can
+lead to OOB read when using kstrtouint. Fix this issue by using
+memdup_user_nul instead of memdup_user.

+Subject: scsi: ufs: qcom: Perform read back after writing unipro mode
+
+From: Andrew Halaney <ahalaney@redhat.com>
+
+[ Upstream commit 823150ecf04f958213cf3bf162187cd1a91c885c ]
+
+Currently, the QUNIPRO_SEL bit is written to and then an mb() is used to
+ensure that completes before continuing.
+
+mb() ensures that the write completes, but completion doesn't mean that it
+isn't stored in a buffer somewhere. The recommendation for ensuring this
+bit has taken effect on the device is to perform a read back to force it to
+make it all the way to the device. This is documented in device-io.rst and
+a talk by Will Deacon on this can be seen over here:
+
+ https://youtu.be/i6DayghhA8Q?si=MiyxB5cKJXSaoc01&t=1678
+
+But, there's really no reason to even ensure completion before
+continuing. The only requirement here is that this write is ordered to this
+endpoint (which readl()/writel() guarantees already). For that reason the
+mb() can be dropped altogether without anything forcing completion.

+On SM8550, depending on the Qunipro, we can run with G5 or G4. For now,

+Subject: selftests/binderfs: use the Makefile's rules, not Make's implicit
+ rules
+
+From: John Hubbard <jhubbard@nvidia.com>
+
+[ Upstream commit 019baf635eb6ffe8d6c1343f81788f02a7e0ed98 ]
+
+First of all, in order to build with clang at all, one must first apply
+Valentin Obst's build fix for LLVM [1]. Once that is done, then when
+building with clang, via:
+
+ make LLVM=1 -C tools/testing/selftests
+
+...the following error occurs:
+
+ clang: error: cannot specify -o when generating multiple output files
+
+This is because clang, unlike gcc, won't accept invocations of this
+form:
+
+ clang file1.c header2.h
+
+While trying to fix this, I noticed that:
+
+a) selftests/lib.mk already avoids the problem, and
+
+b) The binderfs Makefile indavertently bypasses the selftests/lib.mk
+build system, and quitely uses Make's implicit build rules for .c files
+instead.
+
+The Makefile attempts to set up both a dependency and a source file,
+neither of which was needed, because lib.mk is able to automatically
+handle both. This line:
+
+ binderfs_test: binderfs_test.c
+
+...causes Make's implicit rules to run, which builds binderfs_test
+without ever looking at lib.mk.
+
+Fix this by simply deleting the "binderfs_test:" Makefile target and
+letting lib.mk handle it instead.

+When running the bridge IGMP/MLD selftests on debug kernels we can get

+because the membership interval is just 3 seconds and the setup has 2

+Subject: selftests/resctrl: fix clang build failure: use LOCAL_HDRS
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: John Hubbard <jhubbard@nvidia.com>
+
+[ Upstream commit d8171aa4ca72f1a67bf3c14c59441d63c1d2585f ]
+
+First of all, in order to build with clang at all, one must first apply
+Valentin Obst's build fix for LLVM [1]. Once that is done, then when
+building with clang, via:
+
+ make LLVM=1 -C tools/testing/selftests
+
+...the following error occurs:
+
+ clang: error: cannot specify -o when generating multiple output files
+
+This is because clang, unlike gcc, won't accept invocations of this
+form:
+
+ clang file1.c header2.h
+
+Fix this by using selftests/lib.mk facilities for tracking local header
+file dependencies: add them to LOCAL_HDRS, leaving only the .c files to
+be passed to the compiler.

+Subject: selftests: sud_test: return correct emulated syscall value on RISC-V
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Clément Léger <cleger@rivosinc.com>
+
+[ Upstream commit 17c67ed752d6a456602b3dbb25c5ae4d3de5deab ]
+
+Currently, the sud_test expects the emulated syscall to return the
+emulated syscall number. This assumption only works on architectures
+were the syscall calling convention use the same register for syscall
+number/syscall return value. This is not the case for RISC-V and thus
+the return value must be also emulated using the provided ucontext.

+Subject: softirq: Fix suspicious RCU usage in __do_softirq()
+
+From: Zqiang <qiang.zhang1211@gmail.com>
+
+[ Upstream commit 1dd1eff161bd55968d3d46bc36def62d71fb4785 ]
+
+Currently, the condition "__this_cpu_read(ksoftirqd) == current" is used to
+invoke rcu_softirq_qs() in ksoftirqd tasks context for non-RT kernels.
+
+This works correctly as long as the context is actually task context but
+this condition is wrong when:
+
+ - the current task is ksoftirqd
+ - the task is interrupted in a RCU read side critical section
+ - __do_softirq() is invoked on return from interrupt
+
+Syzkaller triggered the following scenario:
+
+ -> finish_task_switch()
+ -> put_task_struct_rcu_user()
+ -> call_rcu(&task->rcu, delayed_put_task_struct)
+ -> __kasan_record_aux_stack()
+ -> pfn_valid()
+ -> rcu_read_lock_sched()
+ <interrupt>
+ __irq_exit_rcu()
+ -> __do_softirq)()
+ -> if (!IS_ENABLED(CONFIG_PREEMPT_RT) &&
+ __this_cpu_read(ksoftirqd) == current)
+ -> rcu_softirq_qs()
+ -> RCU_LOCKDEP_WARN(lock_is_held(&rcu_sched_lock_map))
+
+The rcu quiescent state is reported in the rcu-read critical section, so
+the lockdep warning is triggered.
+
+Fix this by splitting out the inner working of __do_softirq() into a helper
+function which takes an argument to distinguish between ksoftirqd task
+context and interrupted context and invoke it from the relevant call sites
+with the proper context information and use that for the conditional
+invocation of rcu_softirq_qs().

+Subject: tcp: avoid premature drops in tcp_add_backlog()
+
+From: Eric Dumazet <edumazet@google.com>
+
+[ Upstream commit ec00ed472bdb7d0af840da68c8c11bff9f4d9caa ]
+
+While testing TCP performance with latest trees,
+I saw suspect SOCKET_BACKLOG drops.
+
+tcp_add_backlog() computes its limit with :
+
+ limit = (u32)READ_ONCE(sk->sk_rcvbuf) +
+ (u32)(READ_ONCE(sk->sk_sndbuf) >> 1);
+ limit += 64 * 1024;
+
+This does not take into account that sk->sk_backlog.len
+is reset only at the very end of __release_sock().
+
+Both sk->sk_backlog.len and sk->sk_rmem_alloc could reach
+sk_rcvbuf in normal conditions.
+
+We should double sk->sk_rcvbuf contribution in the formula
+to absorb bubbles in the backlog, which happen more often
+for very fast flows.
+
+This change maintains decent protection against abuses.

+Subject: udp: Avoid call to compute_score on multiple sites
+
+From: Gabriel Krisman Bertazi <krisman@suse.de>
+
+[ Upstream commit 50aee97d15113b95a68848db1f0cb2a6c09f753a ]
+
+We've observed a 7-12% performance regression in iperf3 UDP ipv4 and
+ipv6 tests with multiple sockets on Zen3 cpus, which we traced back to
+commit f0ea27e7bfe1 ("udp: re-score reuseport groups when connected
+sockets are present"). The failing tests were those that would spawn
+UDP sockets per-cpu on systems that have a high number of cpus.
+
+Unsurprisingly, it is not caused by the extra re-scoring of the reused
+socket, but due to the compiler no longer inlining compute_score, once
+it has the extra call site in udp4_lib_lookup2. This is augmented by
+the "Safe RET" mitigation for SRSO, needed in our Zen3 cpus.
+
+We could just explicitly inline it, but compute_score() is quite a large
+function, around 300b. Inlining in two sites would almost double
+udp4_lib_lookup2, which is a silly thing to do just to workaround a
+mitigation. Instead, this patch shuffles the code a bit to avoid the
+multiple calls to compute_score. Since it is a static function used in
+one spot, the compiler can safely fold it in, as it did before, without
+increasing the text size.
+
+With this patch applied I ran my original iperf3 testcases. The failing
+cases all looked like this (ipv4):
+ iperf3 -c 127.0.0.1 --udp -4 -f K -b $R -l 8920 -t 30 -i 5 -P 64 -O 2
+
+where $R is either 1G/10G/0 (max, unlimited). I ran 3 times each.
+baseline is v6.9-rc3. harmean == harmonic mean; CV == coefficient of
+variation.
+
+ipv4:
+ 1G 10G MAX
+ HARMEAN (CV) HARMEAN (CV) HARMEAN (CV)
+baseline 1743852.66(0.0208) 1725933.02(0.0167) 1705203.78(0.0386)
+patched 1968727.61(0.0035) 1962283.22(0.0195) 1923853.50(0.0256)
+

+
+This restores the performance we had before the change above with this
+benchmark. We obviously don't expect any real impact when mitigations
+are disabled, but just to be sure it also doesn't regresses:

+
+From: Eric Dumazet <edumazet@google.com>
+
+[ Upstream commit 9aad6e45c4e7d16b2bb7c3794154b828fb4384b4 ]
+
+Some usb drivers try to set small skb->truesize and break
+core networking stacks.
+
+I replace one skb_clone() by an allocation of a fresh
+and small skb, to get minimally sized skbs, like we did
+in commit 1e2c61172342 ("net: cdc_ncm: reduce skb truesize
+in rx path") and 4ce62d5b2f7a ("net: usb: ax88179_178a:
+stop lying about skb->truesize")

+Subject: virt: acrn: Prefer array_size and struct_size over open coded
+ arithmetic
+
+From: Len Baker <len.baker@gmx.com>
+
+[ Upstream commit 746f1b0ac5bf6ecfb71674af210ae476aa714f46 ]
+
+As noted in the "Deprecated Interfaces, Language Features, Attributes,
+and Conventions" documentation [1], size calculations (especially
+multiplication) should not be performed in memory allocator (or similar)
+function arguments due to the risk of them overflowing. This could lead
+to values wrapping around and a smaller allocation being made than the
+caller was expecting. Using those allocations could lead to linear
+overflows of heap memory and other misbehaviors.
+
+So, use the array_size() helper to do the arithmetic instead of the
+argument "count * size" in the vzalloc() function.
+
+Also, take the opportunity to add a flexible array member of struct
+vm_memory_region_op to the vm_memory_region_batch structure. And then,
+change the code accordingly and use the struct_size() helper to do the
+arithmetic instead of the argument "size + size * count" in the kzalloc
+function.
+
+This code was detected with the help of Coccinelle and audited and fixed
+manually.

+
+From: Christoph Hellwig <hch@lst.de>
+
+[ Upstream commit 1b265da7ea1e1ae997fa119c2846bb389eb39c6b ]
+
+Patch series "remove follow_pfn".
+
+This series open codes follow_pfn in the only remaining caller, although
+the code there remains questionable. It then also moves follow_phys into
+the only user and simplifies it a bit.
+
+This patch (of 3):
+
+Switch from follow_pfn to follow_pte so that we can get rid of follow_pfn.
+Note that this doesn't fix any of the pre-existing raciness and lack of
+permission checking in the code.

+From: Baochen Qiang <quic_bqiang@quicinc.com>
+
+[ Upstream commit e57b7d62a1b2f496caf0beba81cec3c90fad80d5 ]
+
+Currently host relies on CE interrupts to get notified that
+the service ready message is ready. This results in timeout
+issue if the interrupt is not fired, due to some unknown
+reasons. See below logs:
+
+[76321.937866] ath10k_pci 0000:02:00.0: wmi service ready event not received
+...
+[76322.016738] ath10k_pci 0000:02:00.0: Could not init core: -110
+
+And finally it causes WLAN interface bring up failure.
+
+Change to give it one more chance here by polling CE rings,
+before failing directly.

+Subject: wifi: carl9170: add a proper sanity check for endpoints
+
+From: Nikita Zhandarovich <n.zhandarovich@fintech.ru>
+
+[ Upstream commit b6dd09b3dac89b45d1ea3e3bd035a3859c0369a0 ]
+
+Syzkaller reports [1] hitting a warning which is caused by presence
+of a wrong endpoint type at the URB sumbitting stage. While there
+was a check for a specific 4th endpoint, since it can switch types
+between bulk and interrupt, other endpoints are trusted implicitly.
+Similar warning is triggered in a couple of other syzbot issues [2].
+
+Fix the issue by doing a comprehensive check of all endpoints
+taking into account difference between high- and full-speed
+configuration.

+Subject: x86/insn: Fix PUSH instruction in x86 instruction decoder opcode map
+
+From: Adrian Hunter <adrian.hunter@intel.com>
+
+[ Upstream commit 59162e0c11d7257cde15f907d19fefe26da66692 ]
+
+The x86 instruction decoder is used not only for decoding kernel
+instructions. It is also used by perf uprobes (user space probes) and by
+perf tools Intel Processor Trace decoding. Consequently, it needs to
+support instructions executed by user space also.
+
+Opcode 0x68 PUSH instruction is currently defined as 64-bit operand size
+only i.e. (d64). That was based on Intel SDM Opcode Map. However that is
+contradicted by the Instruction Set Reference section for PUSH in the
+same manual.
+
+Remove 64-bit operand size only annotation from opcode 0x68 PUSH
+instruction.
+
+Example:
+
+ $ cat pushw.s
+ .global _start
+ .text
+ _start:
+ pushw $0x1234
+ mov $0x1,%eax # system call number (sys_exit)
+ int $0x80
+ $ as -o pushw.o pushw.s
+ $ ld -s -o pushw pushw.o
+ $ objdump -d pushw | tail -4
+ 0000000000401000 <.text>:
+ 401000: 66 68 34 12 pushw $0x1234
+ 401004: b8 01 00 00 00 mov $0x1,%eax
+ 401009: cd 80 int $0x80
+ $ perf record -e intel_pt//u ./pushw
+ [ perf record: Woken up 1 times to write data ]
+ [ perf record: Captured and wrote 0.014 MB perf.data ]

+Subject: x86/mm: Remove broken vsyscall emulation code from the page fault
+ code
+
+From: Linus Torvalds <torvalds@linux-foundation.org>
+
+[ Upstream commit 02b670c1f88e78f42a6c5aee155c7b26960ca054 ]
+
+The syzbot-reported stack trace from hell in this discussion thread
+actually has three nested page faults:
+
+ https://lore.kernel.org/r/000000000000d5f4fc0616e816d4@google.com
+
+... and I think that's actually the important thing here:
+
+ - the first page fault is from user space, and triggers the vsyscall
+ emulation.
+
+ - the second page fault is from __do_sys_gettimeofday(), and that should
+ just have caused the exception that then sets the return value to
+ -EFAULT
+
+ - the third nested page fault is due to _raw_spin_unlock_irqrestore() ->
+ preempt_schedule() -> trace_sched_switch(), which then causes a BPF
+ trace program to run, which does that bpf_probe_read_compat(), which
+ causes that page fault under pagefault_disable().
+
+It's quite the nasty backtrace, and there's a lot going on.
+
+The problem is literally the vsyscall emulation, which sets
+
+ current->thread.sig_on_uaccess_err = 1;
+
+and that causes the fixup_exception() code to send the signal *despite* the
+exception being caught.
+
+And I think that is in fact completely bogus. It's completely bogus
+exactly because it sends that signal even when it *shouldn't* be sent -
+like for the BPF user mode trace gathering.
+
+In other words, I think the whole "sig_on_uaccess_err" thing is entirely
+broken, because it makes any nested page-faults do all the wrong things.
+
+Now, arguably, I don't think anybody should enable vsyscall emulation any
+more, but this test case clearly does.
+
+I think we should just make the "send SIGSEGV" be something that the
+vsyscall emulation does on its own, not this broken per-thread state for
+something that isn't actually per thread.
+
+The x86 page fault code actually tried to deal with the "incorrect nesting"
+by having that:
+
+ if (in_interrupt())
+ return;
+
+which ignores the sig_on_uaccess_err case when it happens in interrupts,
+but as shown by this example, these nested page faults do not need to be
+about interrupts at all.
+
+IOW, I think the only right thing is to remove that horrendously broken
+code.
+
+The attached patch looks like the ObviouslyCorrect(tm) thing to do.
+
+NOTE! This broken code goes back to this commit in 2011:
+
+ 4fc3490114bb ("x86-64: Set siginfo and context on vsyscall emulation faults")
+
+... and back then the reason was to get all the siginfo details right.
+Honestly, I do not for a moment believe that it's worth getting the siginfo
+details right here, but part of the commit says:
+
+ This fixes issues with UML when vsyscall=emulate.
+
+... and so my patch to remove this garbage will probably break UML in this
+situation.
+
+I do not believe that anybody should be running with vsyscall=emulate in
+2024 in the first place, much less if you are doing things like UML. But
+let's see if somebody screams.

+Subject: x86/purgatory: Switch to the position-independent small code model
+
+From: Ard Biesheuvel <ardb@kernel.org>
+
+[ Upstream commit cba786af84a0f9716204e09f518ce3b7ada8555e ]
+
+On x86, the ordinary, position dependent small and kernel code models
+only support placement of the executable in 32-bit addressable memory,
+due to the use of 32-bit signed immediates to generate references to
+global variables. For the kernel, this implies that all global variables
+must reside in the top 2 GiB of the kernel virtual address space, where
+the implicit address bits 63:32 are equal to sign bit 31.
+
+This means the kernel code model is not suitable for other bare metal
+executables such as the kexec purgatory, which can be placed arbitrarily
+in the physical address space, where its address may no longer be
+representable as a sign extended 32-bit quantity. For this reason,
+commit
+
+ e16c2983fba0 ("x86/purgatory: Change compiler flags from -mcmodel=kernel to -mcmodel=large to fix kexec relocation errors")
+
+switched to the large code model, which uses 64-bit immediates for all
+symbol references, including function calls, in order to avoid relying
+on any assumptions regarding proximity of symbols in the final
+executable.
+
+The large code model is rarely used, clunky and the least likely to
+operate in a similar fashion when comparing GCC and Clang, so it is best
+avoided. This is especially true now that Clang 18 has started to emit
+executable code in two separate sections (.text and .ltext), which
+triggers an issue in the kexec loading code at runtime.
+
+The SUSE bugzilla fixes tag points to gcc 13 having issues with the
+large model too and that perhaps the large model should simply not be
+used at all.
+
+Instead, use the position independent small code model, which makes no
+assumptions about placement but only about proximity, where all
+referenced symbols must be within -/+ 2 GiB, i.e., in range for a
+RIP-relative reference. Use hidden visibility to suppress the use of a
+GOT, which carries absolute addresses that are not covered by static ELF
+relocations, and is therefore incompatible with the kexec loader's
+relocation logic.
