+Subject: ACPI: video: Force backlight native for some TongFang devices
+
+From: Werner Sembach <wse@tuxedocomputers.com>
+
+commit c752089f7cf5b5800c6ace4cdd1a8351ee78a598 upstream.
+
+The TongFang PF5PU1G, PF4NU1F, PF5NU1G, and PF5LUXG/TUXEDO BA15 Gen10,
+Pulse 14/15 Gen1, and Pulse 15 Gen2 have the same problem as the Clevo
+NL5xRU and NL5xNU/TUXEDO Aura 15 Gen1 and Gen2:
+They have a working native and video interface. However the default
+detection mechanism first registers the video interface before
+unregistering it again and switching to the native interface during boot.
+This results in a dangling SBIOS request for backlight change for some
+reason, causing the backlight to switch to ~2% once per boot on the first
+power cord connect or disconnect event. Setting the native interface
+explicitly circumvents this buggy behaviour by avoiding the unregistering
+process.

+Subject: ACPI: video: Shortening quirk list by identifying Clevo by board_name
+ only
+
+From: Werner Sembach <wse@tuxedocomputers.com>
+
+commit f0341e67b3782603737f7788e71bd3530012a4f4 upstream.
+
+Taking a recent change in the i8042 quirklist to this one: Clevo
+board_names are somewhat unique, and if not: The generic Board_-/Sys_Vendor
+string "Notebook" doesn't help much anyway. So identifying the devices just
+by the board_name helps keeping the list significantly shorter and might
+even hit more devices requiring the fix.

+Subject: add barriers to buffer_uptodate and set_buffer_uptodate
+
+From: Mikulas Patocka <mpatocka@redhat.com>
+
+commit d4252071b97d2027d246f6a82cbee4d52f618b47 upstream.
+
+Let's have a look at this piece of code in __bread_slow:
+
+ get_bh(bh);
+ bh->b_end_io = end_buffer_read_sync;
+ submit_bh(REQ_OP_READ, 0, bh);
+ wait_on_buffer(bh);
+ if (buffer_uptodate(bh))
+ return bh;
+
+Neither wait_on_buffer nor buffer_uptodate contain any memory barrier.
+Consequently, if someone calls sb_bread and then reads the buffer data,
+the read of buffer data may be executed before wait_on_buffer(bh) on
+architectures with weak memory ordering and it may return invalid data.
+
+Fix this bug by adding a memory barrier to set_buffer_uptodate and an
+acquire barrier to buffer_uptodate (in a similar way as
+folio_test_uptodate and folio_mark_uptodate).

+Subject: ALSA: bcd2000: Fix a UAF bug on the error path of probing
+
+From: Zheyu Ma <zheyuma97@gmail.com>
+
+commit ffb2759df7efbc00187bfd9d1072434a13a54139 upstream.
+
+When the driver fails in snd_card_register() at probe time, it will free
+the 'bcd2k->midi_out_urb' before killing it, which may cause a UAF bug.
+
+The following log can reveal it:
+
+[ 50.727020] BUG: KASAN: use-after-free in bcd2000_input_complete+0x1f1/0x2e0 [snd_bcd2000]

+[ 50.732899] bcd2000_input_complete+0x1f1/0x2e0 [snd_bcd2000]
+
+Fix this by adding usb_kill_urb() before usb_free_urb().

+
+From: Russell King (Oracle) <rmk+kernel@armlinux.org.uk>
+
+[ Upstream commit ec85bd369fd2bfaed6f45dd678706429d4f75b48 ]
+
+When offset is larger than the size of the bit array, we should not
+attempt to access the array as we can perform an access beyond the
+end of the array. Fix this by changing the pre-condition.
+
+Using "cmp r2, r1; bhs ..." covers us for the size == 0 case, since
+this will always take the branch when r1 is zero, irrespective of
+the value of r2. This means we can fix this bug without adding any
+additional code!

+MIME-Version: 1.0

+

+
+emulation_proc_handler() changes table->data for proc_dointvec_minmax
+and can generate the following Oops if called concurrently with itself:
+
+ | Unable to handle kernel NULL pointer dereference at virtual address 0000000000000010
+ | Internal error: Oops: 96000006 [#1] SMP
+ | Call trace:
+ | update_insn_emulation_mode+0xc0/0x148

+ | el0_svc_handler+0x2c/0xa0
+ | el0_svc+0x8/0x200
+
+To fix this issue, keep the table->data as &insn->current_mode and
+use container_of() to retrieve the insn pointer. Another mutex is
+used to protect against the current_mode update but not for retrieving
+insn_emulation as table->data is no longer changing.

+
+As i2c_add_driver could return error if fails, it should be
+better to check the return value.
+However, if the CONFIG_I2C and CONFIG_SPI_MASTER are both true,
+the return value of i2c_add_driver will be covered by
+spi_register_driver.
+Therefore, it is necessary to add check and return error if fails.

+
+Syzbot reported use-after-free Read in ath9k_hif_usb_rx_cb() [0]. The
+problem was in incorrect htc_handle->drv_priv initialization.
+
+Probable call trace which can trigger use-after-free:

+ ath9k_hif_usb_rx_stream()
+ RX_STAT_INC() <--- htc_handle->drv_priv access
+
+In order to not add fancy protection for drv_priv we can move
+htc_handle->drv_priv initialization at the end of the
+ath9k_htc_probe_device() and add helper macro to make
+all *_STAT_* macros NULL safe, since syzbot has reported related NULL
+deref in that macros [1]

+Subject: Bluetooth: L2CAP: Fix use-after-free caused by l2cap_chan_put
+
+From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
+
+commit d0be8347c623e0ac4202a1d4e0373882821f56b0 upstream.
+
+This fixes the following trace which is caused by hci_rx_work starting up
+*after* the final channel reference has been put() during sock_close() but
+*before* the references to the channel have been destroyed, so instead
+the code now rely on kref_get_unless_zero/l2cap_chan_hold_unless_zero to
+prevent referencing a channel that is about to be destroyed.
+
+ refcount_t: increment on 0; use-after-free.

+Subject: can: error: specify the values of data[5..7] of CAN error frames
+
+From: Vincent Mailhol <mailhol.vincent@wanadoo.fr>
+
+[ Upstream commit e70a3263a7eed768d5f947b8f2aff8d2a79c9d97 ]
+
+Currently, data[5..7] of struct can_frame, when used as a CAN error
+frame, are defined as being "controller specific". Device specific
+behaviours are problematic because it prevents someone from writing
+code which is portable between devices.
+
+As a matter of fact, data[5] is never used, data[6] is always used to
+report TX error counter and data[7] is always used to report RX error
+counter. can-utils also relies on this.
+
+This patch updates the comment in the uapi header to specify that
+data[5] is reserved (and thus should not be used) and that data[6..7]
+are used for error counters.
+
+Fixes: 0d66548a10cb ("[CAN]: Add PF_CAN core module")

+Subject: dccp: put dccp_qpolicy_full() and dccp_qpolicy_push() in the same
+ lock
+
+From: Hangyu Hua <hbh25y@gmail.com>
+
+[ Upstream commit a41b17ff9dacd22f5f118ee53d82da0f3e52d5e3 ]
+
+In the case of sk->dccps_qpolicy == DCCPQ_POLICY_PRIO, dccp_qpolicy_full
+will drop a skb when qpolicy is full. And the lock in dccp_sendmsg is
+released before sock_alloc_send_skb and then relocked after
+sock_alloc_send_skb. The following conditions may lead dccp_qpolicy_push
+to add skb to an already full sk_write_queue:
+
+thread1--->lock
+thread1--->dccp_qpolicy_full: queue is full. drop a skb
+thread1--->unlock
+thread2--->lock
+thread2--->dccp_qpolicy_full: queue is not full. no need to drop.
+thread2--->unlock
+thread1--->lock
+thread1--->dccp_qpolicy_push: add a skb. queue is full.
+thread1--->unlock
+thread2--->lock
+thread2--->dccp_qpolicy_push: add a skb!
+thread2--->unlock
+
+Fix this by moving dccp_qpolicy_full.

+Subject: drm/radeon: fix potential buffer overflow in

+
+From: Alexey Kodanev <aleksei.kodanev@bell-sw.com>
+
+[ Upstream commit 136f614931a2bb73616b292cf542da3a18daefd5 ]
+
+The last case label can write two buffers 'mc_reg_address[j]' and
+'mc_data[j]' with 'j' offset equal to SMC_NISLANDS_MC_REGISTER_ARRAY_SIZE
+since there are no checks for this value in both case labels after the
+last 'j++'.
+
+Instead of changing '>' to '>=' there, add the bounds check at the start
+of the second 'case' (the first one already has it).
+
+Also, remove redundant last checks for 'j' index bigger than array size.
+The expression is always false. Moreover, before or after the patch
+'table->last' can be equal to SMC_NISLANDS_MC_REGISTER_ARRAY_SIZE and it
+seems it can be a valid value.
+
+Detected using the static analysis tool - Svace.

+Subject: ext4: recover csum seed of tmp_inode after migrating to extents
+
+From: Li Lingfeng <lilingfeng3@huawei.com>
+
+[ Upstream commit 07ea7a617d6b278fb7acedb5cbe1a81ce2de7d0c ]
+
+When migrating to extents, the checksum seed of temporary inode
+need to be replaced by inode's, otherwise the inode checksums
+will be incorrect when swapping the inodes data.
+
+However, the temporary inode can not match it's checksum to
+itself since it has lost it's own checksum seed.

+Subject: fs: check FMODE_LSEEK to control internal pipe splicing
+
+From: Jason A. Donenfeld <Jason@zx2c4.com>
+
+[ Upstream commit 97ef77c52b789ec1411d360ed99dca1efe4b2c81 ]
+
+The original direct splicing mechanism from Jens required the input to
+be a regular file because it was avoiding the special socket case. It
+also recognized blkdevs as being close enough to a regular file. But it
+forgot about chardevs, which behave the same way and work fine here.
+
+This is an okayish heuristic, but it doesn't totally work. For example,
+a few chardevs should be spliceable here. And a few regular files
+shouldn't. This patch fixes this by instead checking whether FMODE_LSEEK
+is set, which represents decently enough what we need rewinding for when
+splicing to internal pipes.

+From: Liang He <windhl@126.com>
+
+[ Upstream commit 5d07a692f9562f9c06e62cce369e9dd108173a0f ]
+
+We should use of_node_get() when a new reference of device_node
+is created. It is noted that the old reference stored in
+'mm_gc->gc.of_node' should also be decreased.
+
+This patch is based on the fact that there is a call site in function
+'qe_add_gpiochips()' of src file 'drivers\soc\fsl\qe\gpio.c'. In this
+function, of_mm_gpiochip_add_data() is contained in an iteration of
+for_each_compatible_node() which will automatically increase and
+decrease the refcount. So we need additional of_node_get() for the
+reference escape in of_mm_gpiochip_add_data().

+Subject: hwmon: (sht15) Fix wrong assumptions in device remove callback
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
+
+[ Upstream commit 7d4edccc9bbfe1dcdff641343f7b0c6763fbe774 ]
+
+Taking a lock at the beginning of .remove() doesn't prevent new readers.
+With the existing approach it can happen, that a read occurs just when
+the lock was taken blocking the reader until the lock is released at the
+end of the remove callback which then accessed *data that is already
+freed then.
+
+To actually fix this problem the hwmon core needs some adaption. Until
+this is implemented take the optimistic approach of assuming that all
+readers are gone after hwmon_device_unregister() and
+sysfs_remove_group() as most other drivers do. (And once the core
+implements that, taking the lock would deadlock.)
+
+So drop the lock, move the reset to after device unregistration to keep
+the device in a workable state until it's deregistered. Also add a error
+message in case the reset fails and return 0 anyhow. (Returning an error
+code, doesn't stop the platform device unregistration and only results
+in a little helpful error message before the devm cleanup handlers are
+called.)

+Subject: i2c: cadence: Support PEC for SMBus block read
+
+From: Lars-Peter Clausen <lars@metafoo.de>
+
+[ Upstream commit 9fdf6d97f03035ad5298e2d1635036c74c2090ed ]
+
+SMBus packet error checking (PEC) is implemented by appending one
+additional byte of checksum data at the end of the message. This provides
+additional protection and allows to detect data corruption on the I2C bus.
+
+SMBus block reads support variable length reads. The first byte in the read
+message is the number of available data bytes.
+
+The combination of PEC and block read is currently not supported by the
+Cadence I2C driver.
+ * When PEC is enabled the maximum transfer length for block reads
+ increases from 33 to 34 bytes.
+ * The I2C core smbus emulation layer relies on the driver updating the
+ `i2c_msg` `len` field with the number of received bytes. The updated
+ length is used when checking the PEC.
+
+Add support to the Cadence I2C driver for handling SMBus block reads with
+PEC. To determine the maximum transfer length uses the initial `len` value
+of the `i2c_msg`. When PEC is enabled this will be 2, when it is disabled
+it will be 1.
+
+Once a read transfer is done also increment the `len` field by the amount
+of received data bytes.
+
+This change has been tested with a UCM90320 PMBus power monitor, which
+requires block reads to access certain data fields, but also has PEC
+enabled by default.

+
+From: Christian Borntraeger <borntraeger@de.ibm.com>
+
+commit 467d12f5c7842896d2de3ced74e4147ee29e97c8 upstream.
+
+QEMU has a funny new build error message when I use the upstream kernel

+
+This was triggered by commit d5767057c9a ("uapi: rename ext2_swab() to
+swab() and share globally in swab.h"). That patch is doing
+
+ #include <asm/bitsperlong.h>

+but it uses BITS_PER_LONG.
+
+The kernel file asm/bitsperlong.h provide only __BITS_PER_LONG.
+
+Let us use the __ variant in swap.h

+
+From: Laura Abbott <lauraa@codeaurora.org>
+
+commit 121388a31362b0d3176dc1190ac8064b98a61b20 upstream.
+
+Patch series "Command line randomness", v3.
+
+A series to add the kernel command line as a source of randomness.
+
+This patch (of 2):
+
+Stack canary intialization involves getting a random number. Getting this
+random number may involve accessing caches or other architectural specific
+features which are not available until after the architecture is setup.
+Move the stack canary initialization later to accommodate this.

+Subject: kfifo: fix kfifo_to_user() return type
+
+From: Dan Carpenter <dan.carpenter@oracle.com>
+
+[ Upstream commit 045ed31e23aea840648c290dbde04797064960db ]
+
+The kfifo_to_user() macro is supposed to return zero for success or
+negative error codes. Unfortunately, there is a signedness bug so it
+returns unsigned int. This only affects callers which try to save the
+result in ssize_t and as far as I can see the only place which does that
+is line6_hwdep_read().
+
+TL;DR: s/_uint/_int/.

+Subject: KVM: x86: Mark TSS busy during LTR emulation _after_ all fault checks
+
+From: Sean Christopherson <seanjc@google.com>
+
+commit ec6e4d863258d4bfb36d48d5e3ef68140234d688 upstream.
+
+Wait to mark the TSS as busy during LTR emulation until after all fault
+checks for the LTR have passed. Specifically, don't mark the TSS busy if
+the new TSS base is non-canonical.
+
+Opportunistically drop the one-off !seg_desc.PRESENT check for TR as the
+only reason for the early check was to avoid marking a !PRESENT TSS as
+busy, i.e. the common !PRESENT is now done before setting the busy bit.

+Subject: Makefile: link with -z noexecstack --no-warn-rwx-segments
+
+From: Nick Desaulniers <ndesaulniers@google.com>
+
+commit 0d362be5b14200b77ecc2127936a5ff82fbffe41 upstream.
+
+Users of GNU ld (BFD) from binutils 2.39+ will observe multiple
+instances of a new warning when linking kernels in the form:
+
+ ld: warning: vmlinux: missing .note.GNU-stack section implies executable stack
+ ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
+ ld: warning: vmlinux has a LOAD segment with RWX permissions
+
+Generally, we would like to avoid the stack being executable. Because
+there could be a need for the stack to be executable, assembler sources
+have to opt-in to this security feature via explicit creation of the
+.note.GNU-stack feature (which compilers create by default) or command
+line flag --noexecstack. Or we can simply tell the linker the
+production of such sections is irrelevant and to link the stack as
+--noexecstack.
+
+LLVM's LLD linker defaults to -z noexecstack, so this flag isn't
+strictly necessary when linking with LLD, only BFD, but it doesn't hurt
+to be explicit here for all linkers IMO. --no-warn-rwx-segments is
+currently BFD specific and only available in the current latest release,
+so it's wrapped in an ld-option check.
+
+While the kernel makes extensive usage of ELF sections, it doesn't use
+permissions from ELF segments.

+Subject: media: hdpvr: fix error value returns in hdpvr_read
+
+From: Niels Dossche <dossche.niels@gmail.com>
+
+[ Upstream commit 359c27c6ddbde404f44a9c0d3ec88ccd1e2042f2 ]
+
+Error return values are supposed to be negative in hdpvr_read. Most
+error returns are currently handled via an unsigned integer "ret". When
+setting a negative error value to "ret", the value actually becomes a
+large positive value, because "ret" is unsigned. Later on, the "ret"
+value is returned. But as ssize_t is a 64-bit signed number, the error
+return value stays a large positive integer instead of a negative
+integer. This can cause an error value to be interpreted as the read
+size, which can cause a buffer overread for applications relying on the
+returned size.

+Subject: memstick/ms_block: Fix some incorrect memory allocation
+
+From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
+
+[ Upstream commit 2e531bc3e0d86362fcd8a577b3278d9ef3cc2ba0 ]
+
+Some functions of the bitmap API take advantage of the fact that a bitmap
+is an array of long.
+
+So, to make sure this assertion is correct, allocate bitmaps with
+bitmap_zalloc() instead of kzalloc()+hand-computed number of bytes.
+
+While at it, also use bitmap_free() instead of kfree() to keep the
+semantic.

+None of the in-tree instantiations of struct t7l66xb_platform_data

+
+[ Upstream commit 7f82f922319ede486540e8746769865b9508d2c2 ]
+
+Since the beginning, charged is set to 0 to avoid calling vm_unacct_memory
+twice because vm_unacct_memory will be called by above unmap_region. But
+since commit 4f74d2c8e827 ("vm: remove 'nr_accounted' calculations from
+the unmap_vmas() interfaces"), unmap_region doesn't call vm_unacct_memory
+anymore. So charged shouldn't be set to 0 now otherwise the calling to
+paired vm_unacct_memory will be missed and leads to imbalanced account.

+Subject: mtd: sm_ftl: Fix deadlock caused by cancel_work_sync in sm_release
+
+From: Duoming Zhou <duoming@zju.edu.cn>
+
+[ Upstream commit a61528d997619a518ee8c51cf0ef0513021afaff ]
+
+There is a deadlock between sm_release and sm_cache_flush_work
+which is a work item. The cancel_work_sync in sm_release will
+not return until sm_cache_flush_work is finished. If we hold
+mutex_lock and use cancel_work_sync to wait the work item to
+finish, the work item also requires mutex_lock. As a result,
+the sm_release will be blocked forever. The race condition is
+shown below:
+
+ (Thread 1) | (Thread 2)
+sm_release |
+ mutex_lock(&ftl->mutex) | sm_cache_flush_work
+ | mutex_lock(&ftl->mutex)
+ cancel_work_sync | ...
+
+This patch moves del_timer_sync and cancel_work_sync out of
+mutex_lock in order to mitigate deadlock.

+Subject: net: ping6: Fix memleak in ipv6_renew_options().
+
+From: Kuniyuki Iwashima <kuniyu@amazon.com>
+
+commit e27326009a3d247b831eda38878c777f6f4eb3d1 upstream.
+
+When we close ping6 sockets, some resources are left unfreed because
+pingv6_prot is missing sk->sk_prot->destroy(). As reported by
+syzbot [0], just three syscalls leak 96 bytes and easily cause OOM.
+
+ struct ipv6_sr_hdr *hdr;
+ char data[24] = {0};
+ int fd;
+
+ hdr = (struct ipv6_sr_hdr *)data;
+ hdr->hdrlen = 2;
+ hdr->type = IPV6_SRCRT_TYPE_4;
+
+ fd = socket(AF_INET6, SOCK_DGRAM, NEXTHDR_ICMP);
+ setsockopt(fd, IPPROTO_IPV6, IPV6_RTHDR, data, 24);
+ close(fd);
+
+To fix memory leaks, let's add a destroy function.
+
+Note the socket() syscall checks if the GID is within the range of
+net.ipv4.ping_group_range. The default value is [1, 0] so that no
+GID meets the condition (1 <= GID <= 0). Thus, the local DoS does
+not succeed until we change the default value. However, at least
+Ubuntu/Fedora/RHEL loosen it.
+
+ $ cat /usr/lib/sysctl.d/50-default.conf
+ ...
+ -net.ipv4.ping_group_range = 0 2147483647
+
+Also, there could be another path reported with these options, and
+some of them require CAP_NET_RAW.
+
+ setsockopt
+ IPV6_ADDRFORM (inet6_sk(sk)->pktoptions)
+ IPV6_RECVPATHMTU (inet6_sk(sk)->rxpmtu)
+ IPV6_HOPOPTS (inet6_sk(sk)->opt)
+ IPV6_RTHDRDSTOPTS (inet6_sk(sk)->opt)
+ IPV6_RTHDR (inet6_sk(sk)->opt)
+ IPV6_DSTOPTS (inet6_sk(sk)->opt)
+ IPV6_2292PKTOPTIONS (inet6_sk(sk)->opt)
+
+ getsockopt
+ IPV6_FLOWLABEL_MGR (inet6_sk(sk)->ipv6_fl_list)
+
+For the record, I left a different splat with syzbot's one.

+Subject: net: rose: fix netdev reference changes
+
+From: Eric Dumazet <edumazet@google.com>
+
+[ Upstream commit 931027820e4dafabc78aff82af59f8c1c4bd3128 ]
+
+Bernard reported that trying to unload rose module would lead
+to infamous messages:
+
+unregistered_netdevice: waiting for rose0 to become free. Usage count = xx
+
+This patch solves the issue, by making sure each socket referring to
+a netdevice holds a reference count on it, and properly releases it
+in rose_release().
+
+rose_dev_first() is also fixed to take a device reference
+before leaving the rcu_read_locked section.
+
+Following patch will add ref_tracker annotations to ease
+future bug hunting.

+Domingo Dirutigliano and Nicola Guerrera report kernel panic when

+
+The IP/IPv6 stack pulls the IP(v6) header from the packet after the

+
+If user truncates the packet below the header size, this skb_pull() will

+Subject: platform/olpc: Fix uninitialized data in debugfs write
+
+From: Dan Carpenter <dan.carpenter@oracle.com>
+
+[ Upstream commit 40ec787e1adf302c11668d4cc69838f4d584187d ]
+
+The call to:
+
+ size = simple_write_to_buffer(cmdbuf, sizeof(cmdbuf), ppos, buf, size);
+
+will succeed if at least one byte is written to the "cmdbuf" buffer.
+The "*ppos" value controls which byte is written. Another problem is
+that this code does not check for errors so it's possible for the entire
+buffer to be uninitialized.
+
+Inintialize the struct to zero to prevent reading uninitialized stack
+data.
+
+Debugfs is normally only writable by root so the impact of this bug is
+very minimal.

+Subject: PM: hibernate: defer device probing when resuming from hibernation
+
+From: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp>
+
+[ Upstream commit 8386c414e27caba8501119948e9551e52b527f59 ]
+
+syzbot is reporting hung task at misc_open() [1], for there is a race
+window of AB-BA deadlock which involves probe_count variable. Currently
+wait_for_device_probe() from snapshot_open() from misc_open() can sleep
+forever with misc_mtx held if probe_count cannot become 0.
+
+When a device is probed by hub_event() work function, probe_count is
+incremented before the probe function starts, and probe_count is
+decremented after the probe function completed.
+
+There are three cases that can prevent probe_count from dropping to 0.
+
+ (a) A device being probed stopped responding (i.e. broken/malicious
+ hardware).
+
+ (b) A process emulating a USB device using /dev/raw-gadget interface
+ stopped responding for some reason.
+
+ (c) New device probe requests keeps coming in before existing device
+ probe requests complete.
+
+The phenomenon syzbot is reporting is (b). A process which is holding
+system_transition_mutex and misc_mtx is waiting for probe_count to become
+0 inside wait_for_device_probe(), but the probe function which is called
+ from hub_event() work function is waiting for the processes which are
+blocked at mutex_lock(&misc_mtx) to respond via /dev/raw-gadget interface.
+
+This patch mitigates (b) by deferring wait_for_device_probe() from
+snapshot_open() to snapshot_write() and snapshot_ioctl(). Please note that
+the possibility of (b) remains as long as any thread which is emulating a
+USB device via /dev/raw-gadget interface can be blocked by uninterruptible
+blocking operations (e.g. mutex_lock()).
+
+Please also note that (a) and (c) are not addressed. Regarding (c), we
+should change the code to wait for only one device which contains the
+image for resuming from hibernation. I don't know how to address (a), for
+use of timeout for wait_for_device_probe() might result in loss of user
+data in the image. Maybe we should require the userland to wait for the
+image device before opening /dev/snapshot interface.

+
+[ Upstream commit f4b39e88b42d13366b831270306326b5c20971ca ]
+
+The recent change to the PHB numbering logic has a logic error in the
+handling of "ibm,opal-phbid".
+
+When an "ibm,opal-phbid" property is present, &prop is written to and
+ret is set to zero.
+
+The following call to of_alias_get_id() is skipped because ret == 0.
+
+But then the if (ret >= 0) is true, and the body of that if statement
+sets prop = ret which throws away the value that was just read from
+"ibm,opal-phbid".
+
+Fix the logic by only doing the ret >= 0 check in the of_alias_get_id()
+case.

+
+Other Linux architectures use DT property 'linux,pci-domain' for
+specifying fixed PCI domain of PCI controller specified in Device-Tree.
+
+And lot of Freescale powerpc boards have defined numbered pci alias in
+Device-Tree for every PCIe controller which number specify preferred PCI
+domain.
+
+So prefer usage of DT property 'linux,pci-domain' (via function
+of_get_pci_domain_nr()) and DT pci alias (via function
+of_alias_get_id()) on powerpc architecture for assigning PCI domain to
+PCI controller.

+Subject: profiling: fix shift too large makes kernel panic
+
+From: Chen Zhongjin <chenzhongjin@huawei.com>
+
+[ Upstream commit 0fe6ee8f123a4dfb529a5aff07536bb481f34043 ]
+
+2d186afd04d6 ("profiling: fix shift-out-of-bounds bugs") limits shift
+value by [0, BITS_PER_LONG -1], which means [0, 63].
+
+However, syzbot found that the max shift value should be the bit number of
+(_etext - _stext). If shift is outside of this, the "buffer_bytes" will
+be zero and will cause kzalloc(0). Then the kernel panics due to
+dereferencing the returned pointer 16.
+
+This can be easily reproduced by passing a large number like 60 to enable
+profiling and then run readprofile.
+
+LOGS:
+ BUG: kernel NULL pointer dereference, address: 0000000000000010
+ #PF: supervisor write access in kernel mode

+Subject: random: only call boot_init_stack_canary() once
+
+From: Hans-Christian Noren Egtvedt <hegtvedt@cisco.com>
+
+In commit 166a592cad36 ("random: move rand_initialize() earlier") the
+boot_init_stack_canary() call was added after the new random_init()
+call.
+
+However, the upstream commit d55535232c3d ("random: move
+rand_initialize() earlier") also included removing the earlier call to
+boot_init_stack_canary(), making sure this call is done after
+random_init().
+
+Hence fix what I assume is a wrong merge conflict resolution on the
+linux-4.9.y stable branch.

+
+From: Zhu Yanjun <yanjun.zhu@linux.dev>
+
+[ Upstream commit fd5382c5805c4bcb50fd25b7246247d3f7114733 ]
+
+In the function rxe_create_qp(), rxe_qp_from_init() is called to
+initialize qp, internally things like the spin locks are not setup until
+rxe_qp_init_req().
+
+If an error occures before this point then the unwind will call
+rxe_cleanup() and eventually to rxe_qp_do_cleanup()/rxe_cleanup_task()
+which will oops when trying to access the uninitialized spinlock.
+
+Move the spinlock initializations earlier before any failures.

+

+
+The wcnss_get_irq function is expected to return a value > 0 in the
+event that an IRQ is succssfully obtained, but it instead returns 0.
+This causes the stop and ready IRQs to never actually be used despite
+being defined in the device-tree. This patch fixes that.

+Subject: scsi: smartpqi: Fix DMA direction for RAID requests
+
+From: Mahesh Rajashekhara <Mahesh.Rajashekhara@microchip.com>
+
+[ Upstream commit 69695aeaa6621bc49cdd7a8e5a8d1042461e496e ]
+
+Correct a SOP READ and WRITE DMA flags for some requests.
+
+This update corrects DMA direction issues with SCSI commands removed from
+the controller's internal lookup table.
+
+Currently, SCSI READ BLOCK LIMITS (0x5) was removed from the controller
+lookup table and exposed a DMA direction flag issue.
+
+SCSI READ BLOCK LIMITS was recently removed from our controller lookup
+table so the controller uses the respective IU flag field to set the DMA
+data direction. Since the DMA direction is incorrect the FW never completes
+the request causing a hang.
+
+Some SCSI commands which use SCSI READ BLOCK LIMITS
+
+ * sg_map
+ * mt -f /dev/stX status
+
+After updating controller firmware, users may notice their tape units
+failing. This patch resolves the issue.
+
+Also, the AIO path DMA direction is correct.
+
+The DMA direction flag is a day-one bug with no reported BZ.
+

+Subject: selinux: Convert isec->lock into a spinlock
+
+From: Andreas Gruenbacher <agruenba@redhat.com>
+
+commit 9287aed2ad1ff1bde5eb190bcd6dccd5f1cf47d3 upstream.
+
+Convert isec->lock from a mutex into a spinlock. Instead of holding
+the lock while sleeping in inode_doinit_with_dentry, set
+isec->initialized to LABEL_PENDING and release the lock. Then, when
+the sid has been determined, re-acquire the lock. If isec->initialized
+is still set to LABEL_PENDING, set isec->sid; otherwise, the sid has
+been set by another task (LABEL_INITIALIZED) or invalidated
+(LABEL_INVALID) in the meantime.
+
+This fixes a deadlock on gfs2 where
+
+ * one task is in inode_doinit_with_dentry -> gfs2_getxattr, holds
+ isec->lock, and tries to acquire the inode's glock, and
+
+ * another task is in do_xmote -> inode_go_inval ->
+ selinux_inode_invalidate_secctx, holds the inode's glock, and
+ tries to acquire isec->lock.

+From: Tianyue Ren <rentianyue@kylinos.cn>
+
+commit 83370b31a915493231e5b9addc72e4bef69f8d31 upstream.
+
+Mark the inode security label as invalid if we cannot find
+a dentry so that we will retry later rather than marking it
+initialized with the unlabeled SID.

+Subject: selinux: fix inode_doinit_with_dentry() LABEL_INVALID error handling
+
+From: Paul Moore <paul@paul-moore.com>
+
+commit 200ea5a2292dc444a818b096ae6a32ba3caa51b9 upstream.
+
+A previous fix, commit 83370b31a915 ("selinux: fix error initialization
+in inode_doinit_with_dentry()"), changed how failures were handled
+before a SELinux policy was loaded. Unfortunately that patch was
+potentially problematic for two reasons: it set the isec->initialized
+state without holding a lock, and it didn't set the inode's SELinux
+label to the "default" for the particular filesystem. The later can
+be a problem if/when a later attempt to revalidate the inode fails
+and SELinux reverts to the existing inode label.
+
+This patch should restore the default inode labeling that existed
+before the original fix, without affecting the LABEL_INVALID marking
+such that revalidation will still be attempted in the future.
+

+Subject: tcp: make retransmitted SKB fit into the send window
+
+From: Yonglong Li <liyonglong@chinatelecom.cn>
+
+[ Upstream commit 536a6c8e05f95e3d1118c40ae8b3022ee2d05d52 ]
+
+current code of __tcp_retransmit_skb only check TCP_SKB_CB(skb)->seq
+in send window, and TCP_SKB_CB(skb)->seq_end maybe out of send window.
+If receiver has shrunk his window, and skb is out of new window, it
+should retransmit a smaller portion of the payload.
+
+test packetdrill script:
+ 0 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3
+ +0 fcntl(3, F_GETFL) = 0x2 (flags O_RDWR)
+ +0 fcntl(3, F_SETFL, O_RDWR|O_NONBLOCK) = 0
+
+ +0 connect(3, ..., ...) = -1 EINPROGRESS (Operation now in progress)

+
+when cient retract window to 1001, send window is [4001,5002],
+but TLP send 5001-6001 packet which is out of send window.

+From: Daniel Starke <daniel.starke@siemens.com>
+
+[ Upstream commit 18a948c7d90995d127785e308fa7b701df4c499f ]
+
+n_gsm is based on the 3GPP 07.010 and its newer version is the 3GPP 27.010.
+See https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=1516
+The changes from 07.010 to 27.010 are non-functional. Therefore, I refer to
+the newer 27.010 here. Chapter 5.3.3 defines the DM response. There exists
+no DM command. However, the current implementation incorrectly sends DM as
+command in case of unexpected UIH frames in gsm_queue().
+Correct this behavior by always sending DM as response.

+
+From: Daniel Starke <daniel.starke@siemens.com>
+
+[ Upstream commit bec0224816d19abe4fe503586d16d51890540615 ]
+
+n_gsm is based on the 3GPP 07.010 and its newer version is the 3GPP 27.010.
+See https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=1516
+The changes from 07.010 to 27.010 are non-functional. Therefore, I refer to
+the newer 27.010 here. Chapter 5.4.6.3.6 states that FCoff stops the
+transmission on all channels except the control channel. This is already
+implemented in gsm_data_kick(). However, chapter 5.4.8.1 explains that this
+shall result in the same behavior as software flow control on the ldisc in
+advanced option mode. That means only flow control frames shall be sent
+during flow off. The current implementation does not consider this case.
+
+Change gsm_data_kick() to send only flow control frames if constipated to
+abide the standard. gsm_read_ea_val() and gsm_is_flow_ctrl_msg() are
+introduced as helper functions for this.
+It is planned to use gsm_read_ea_val() in later code cleanups for other
+functions, too.

+
+From: Daniel Starke <daniel.starke@siemens.com>
+
+[ Upstream commit 4fae831b3a71fc5a44cc5c7d0b8c1267ee7659f5 ]
+
+In the current implementation control packets are re-transmitted even if
+the control channel closed down during T2. This is wrong.
+Check whether the control channel is open before re-transmitting any
+packets. Note that control channel open/close is handled by T1 and not T2
+and remains unaffected by this.

+Subject: tty: n_gsm: fix race condition in gsmld_write()
+
+From: Daniel Starke <daniel.starke@siemens.com>
+
+[ Upstream commit 32dd59f96924f45e33bc79854f7a00679c0fa28e ]
+
+The function may be used by the user directly and also by the n_gsm
+internal functions. They can lead into a race condition which results in
+interleaved frames if both are writing at the same time. The receiving side
+is not able to decode those interleaved frames correctly.
+
+Add a lock around the low side tty write to avoid race conditions and frame
+interleaving between user originated writes and n_gsm writes.

+Subject: tty: n_gsm: fix wrong T1 retry count handling
+
+From: Daniel Starke <daniel.starke@siemens.com>
+
+[ Upstream commit f30e10caa80aa1f35508bc17fc302dbbde9a833c ]
+
+n_gsm is based on the 3GPP 07.010 and its newer version is the 3GPP 27.010.
+See https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=1516
+The changes from 07.010 to 27.010 are non-functional. Therefore, I refer to
+the newer 27.010 here. Chapter 5.7.3 states that the valid range for the
+maximum number of retransmissions (N2) is from 0 to 255 (both including).
+gsm_dlci_t1() handles this number incorrectly by performing N2 - 1
+retransmission attempts. Setting N2 to zero results in more than 255
+retransmission attempts.
+Fix gsm_dlci_t1() to comply with 3GPP 27.010.

+In the function vt8623fb_set_par(), the value of 'screen_size' is
+calculated by the user input. If the user provides the improper value,
+the value of 'screen_size' may larger than 'info->screen_size', which
+may cause the following bug:

+ il4965_rs_fill_link_cmd()
+
+From: Alexey Kodanev <aleksei.kodanev@bell-sw.com>
+
+[ Upstream commit a8eb8e6f7159c7c20c0ddac428bde3d110890aa7 ]
+
+As a result of the execution of the inner while loop, the value
+of 'idx' can be equal to LINK_QUAL_MAX_RETRY_NUM. However, this
+is not checked after the loop and 'idx' is used to write the
+LINK_QUAL_MAX_RETRY_NUM size array 'lq_cmd->rs_table[idx]' below
+in the outer loop.
+
+The fix is to check the new value of 'idx' inside the nested loop,
+and break both loops if index equals the size. Checking it at the
+start is now pointless, so let's remove it.
+
+Detected using the static analysis tool - Svace.

+Subject: x86: link vdso and boot with -z noexecstack --no-warn-rwx-segments
+
+From: Nick Desaulniers <ndesaulniers@google.com>
+
+commit ffcf9c5700e49c0aee42dcba9a12ba21338e8136 upstream.
+
+Users of GNU ld (BFD) from binutils 2.39+ will observe multiple
+instances of a new warning when linking kernels in the form:
+
+ ld: warning: arch/x86/boot/pmjump.o: missing .note.GNU-stack section implies executable stack
+ ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
+ ld: warning: arch/x86/boot/compressed/vmlinux has a LOAD segment with RWX permissions
+
+Generally, we would like to avoid the stack being executable. Because
+there could be a need for the stack to be executable, assembler sources
+have to opt-in to this security feature via explicit creation of the
+.note.GNU-stack feature (which compilers create by default) or command
+line flag --noexecstack. Or we can simply tell the linker the
+production of such sections is irrelevant and to link the stack as
+--noexecstack.
+
+LLVM's LLD linker defaults to -z noexecstack, so this flag isn't
+strictly necessary when linking with LLD, only BFD, but it doesn't hurt
+to be explicit here for all linkers IMO. --no-warn-rwx-segments is
+currently BFD specific and only available in the current latest release,
+so it's wrapped in an ld-option check.
+
+While the kernel makes extensive usage of ELF sections, it doesn't use
+permissions from ELF segments.

+Subject: x86/numa: Use cpumask_available instead of hardcoded NULL check
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit

+From: Siddh Raman Pant <code@siddh.me>
+
+[ Upstream commit 625395c4a0f4775e0fe00f616888d2e6c1ba49db ]
+
+GCC-12 started triggering a new warning:
+
+ arch/x86/mm/numa.c: In function ‘cpumask_of_node’:
+ arch/x86/mm/numa.c:916:39: warning: the comparison will always evaluate as ‘false’ for the address of ‘node_to_cpumask_map’ will never be NULL [-Waddress]
+ 916 | if (node_to_cpumask_map[node] == NULL) {
+ | ^~
+
+node_to_cpumask_map is of type cpumask_var_t[].
+
+When CONFIG_CPUMASK_OFFSTACK is set, cpumask_var_t is typedef'd to a
+pointer for dynamic allocation, else to an array of one element. The
+"wicked game" can be checked on line 700 of include/linux/cpumask.h.
+
+The original code in debug_cpumask_set_cpu() and cpumask_of_node() were
+probably written by the original authors with CONFIG_CPUMASK_OFFSTACK=y
+(i.e. dynamic allocation) in mind, checking if the cpumask was available
+via a direct NULL check.
+
+When CONFIG_CPUMASK_OFFSTACK is not set, GCC gives the above warning
+while compiling the kernel.
+
+Fix that by using cpumask_available(), which does the NULL check when
+CONFIG_CPUMASK_OFFSTACK is set, otherwise returns true. Use it wherever
+such checks are made.
+
+Conditional definitions of cpumask_available() can be found along with
+the definition of cpumask_var_t. Check the cpumask.h reference mentioned
+above.

+Fixes: de2d9445f162 ("x86: Unify node_to_cpumask_map handling between 32 and 64bit")
