+Subject: ACPI: resource: Add another DMI match for the TongFang GMxXGxx
+
+From: Werner Sembach <wse@tuxedocomputers.com>
+
+commit a98cfe6ff15b62f94a44d565607a16771c847bc6 upstream.
+
+Internal documentation suggest that the TUXEDO Polaris 15 Gen5 AMD might
+have GMxXGxX as the board name instead of GMxXGxx.
+
+Adding both to be on the safe side.

+Subject: btrfs: subpage: fix the bitmap dump which can cause bitmap corruption
+
+From: Qu Wenruo <wqu@suse.com>
+
+commit 77b0b98bb743f5d04d8f995ba1936e1143689d4a upstream.
+
+In commit 75258f20fb70 ("btrfs: subpage: dump extra subpage bitmaps for
+debug") an internal macro GET_SUBPAGE_BITMAP() is introduced to grab the
+bitmap of each attribute.
+
+But that commit is using bitmap_cut() which will do the left shift of
+the larger bitmap, causing incorrect values.
+
+Thankfully this bitmap_cut() is only called for debug usage, and so far
+it's not yet causing problem.
+
+Fix it to use bitmap_read() to only grab the desired sub-bitmap.
+

+Subject: debugobjects: Fix conditions in fill_pool()
+
+From: Zhen Lei <thunder.leizhen@huawei.com>
+
+commit 684d28feb8546d1e9597aa363c3bfcf52fe250b7 upstream.
+
+fill_pool() uses 'obj_pool_min_free' to decide whether objects should be
+handed back to the kmem cache. But 'obj_pool_min_free' records the lowest
+historical value of the number of objects in the object pool and not the
+minimum number of objects which should be kept in the pool.
+
+Use 'debug_objects_pool_min_level' instead, which holds the minimum number
+which was scaled to the number of CPUs at boot time.
+
+[ tglx: Massage change log ]

+From: Mikhail Lobanov <m.lobanov@rosalinux.ru>
+
+commit a5e61b50c9f44c5edb6e134ede6fee8806ffafa9 upstream.
+
+If the net_conf pointer is NULL and the code attempts to access its
+fields without a check, it will lead to a null pointer dereference.
+Add a NULL check before dereferencing the pointer.

+Subject: drbd: Fix atomicity violation in drbd_uuid_set_bm()
+
+From: Qiu-ji Chen <chenqiuji666@gmail.com>
+
+commit 2f02b5af3a4482b216e6a466edecf6ba8450fa45 upstream.
+
+The violation of atomicity occurs when the drbd_uuid_set_bm function is
+executed simultaneously with modifying the value of
+device->ldev->md.uuid[UI_BITMAP]. Consider a scenario where, while
+device->ldev->md.uuid[UI_BITMAP] passes the validity check when its
+value is not zero, the value of device->ldev->md.uuid[UI_BITMAP] is
+written to zero. In this case, the check in drbd_uuid_set_bm might refer
+to the old value of device->ldev->md.uuid[UI_BITMAP] (before locking),
+which allows an invalid value to pass the validity check, resulting in
+inconsistency.
+
+To address this issue, it is recommended to include the data validity
+check within the locked section of the function. This modification
+ensures that the value of device->ldev->md.uuid[UI_BITMAP] does not
+change during the validation process, thereby maintaining its integrity.
+
+This possible bug is found by an experimental static analysis tool
+developed by our team. This tool analyzes the locking APIs to extract
+function pairs that can be concurrently executed, and then analyzes the
+instructions in the paired functions to identify possible concurrency
+bugs including data races and atomicity violations.

+Subject: efistub/tpm: Use ACPI reclaim memory for event log to avoid corruption
+
+From: Ard Biesheuvel <ardb@kernel.org>
+
+commit 77d48d39e99170b528e4f2e9fc5d1d64cdedd386 upstream.
+
+The TPM event log table is a Linux specific construct, where the data
+produced by the GetEventLog() boot service is cached in memory, and
+passed on to the OS using an EFI configuration table.
+
+The use of EFI_LOADER_DATA here results in the region being left
+unreserved in the E820 memory map constructed by the EFI stub, and this
+is the memory description that is passed on to the incoming kernel by
+kexec, which is therefore unaware that the region should be reserved.
+
+Even though the utility of the TPM2 event log after a kexec is
+questionable, any corruption might send the parsing code off into the
+weeds and crash the kernel. So let's use EFI_ACPI_RECLAIM_MEMORY
+instead, which is always treated as reserved by the E820 conversion
+logic.

+Subject: perf/x86/intel: Allow to setup LBR for counting event for BPF
+
+From: Kan Liang <kan.liang@linux.intel.com>
+
+commit ef493f4b122d6b14a6de111d1acac1eab1d673b0 upstream.
+
+The BPF subsystem may capture LBR data on a counting event. However, the
+current implementation assumes that LBR can/should only be used with
+sampling events.
+
+For instance, retsnoop tool ([0]) makes an extensive use of this
+functionality and sets up perf event as follows:
+
+       struct perf_event_attr attr;
+
+       memset(&attr, 0, sizeof(attr));
+       attr.size = sizeof(attr);
+       attr.type = PERF_TYPE_HARDWARE;
+       attr.config = PERF_COUNT_HW_CPU_CYCLES;
+       attr.sample_type = PERF_SAMPLE_BRANCH_STACK;
+       attr.branch_sample_type = PERF_SAMPLE_BRANCH_KERNEL;
+
+To limit the LBR for a sampling event is to avoid unnecessary branch
+stack setup for a counting event in the sample read. Because LBR is only
+read in the sampling event's overflow.
+
+Although in most cases LBR is used in sampling, there is no HW limit to
+bind LBR to the sampling mode. Allow an LBR setup for a counting event
+unless in the sample read mode.
+

+Subject: perf/x86/intel/pt: Fix sampling synchronization
+
+From: Adrian Hunter <adrian.hunter@intel.com>
+
+commit d92792a4b26e50b96ab734cbe203d8a4c932a7a9 upstream.
+
+pt_event_snapshot_aux() uses pt->handle_nmi to determine if tracing
+needs to be stopped, however tracing can still be going because
+pt->handle_nmi is set to zero before tracing is stopped in pt_event_stop,
+whereas pt_event_snapshot_aux() requires that tracing must be stopped in
+order to copy a sample of trace from the buffer.
+
+Instead call pt_config_stop() always, which anyway checks config for
+RTIT_CTL_TRACEEN and does nothing if it is already clear.
+
+Note pt_event_snapshot_aux() can continue to use pt->handle_nmi to
+determine if the trace needs to be restarted afterwards.

+Due to the lack of checks on the clc array, if the firmware supports

+The definition of GET_RX_DESC_BW is incorrect. Fix it according to the
+GET_RX_STATUS_DESC_BW_8703B macro from the official driver.

+
+commit a71ed5898dfae68262f79277915d1dfe34586bc6 upstream.
+
+"iw dev wlp2s0 station dump" shows incorrect rx bitrate:
+
+tx bitrate:     866.7 MBit/s VHT-MCS 9 80MHz short GI VHT-NSS 2
+rx bitrate:     86.7 MBit/s VHT-MCS 9 VHT-NSS 1
+
+This is because the RX band width is calculated incorrectly. Fix the
+calculation according to the phydm_rxsc_2_bw() function from the
+official drivers.
+
+After:
+
+tx bitrate:     866.7 MBit/s VHT-MCS 9 80MHz short GI VHT-NSS 2
+rx bitrate:     390.0 MBit/s VHT-MCS 9 80MHz VHT-NSS 1
+
+It also works correctly with the AP configured for 20 MHz and 40 MHz.
+
+Tested with RTL8822CE.

+Subject: x86/entry: Remove unwanted instrumentation in common_interrupt()
+
+From: Dmitry Vyukov <dvyukov@google.com>
+
+commit 477d81a1c47a1b79b9c08fc92b5dea3c5143800b upstream.
+
+common_interrupt() and related variants call kvm_set_cpu_l1tf_flush_l1d(),
+which is neither marked noinstr nor __always_inline.
+
+So compiler puts it out of line and adds instrumentation to it.  Since the
+call is inside of instrumentation_begin/end(), objtool does not warn about
+it.
+
+The manifestation is that KCOV produces spurious coverage in
+kvm_set_cpu_l1tf_flush_l1d() in random places because the call happens when
+preempt count is not yet updated to say that the kernel is in an interrupt.
+
+Mark kvm_set_cpu_l1tf_flush_l1d() as __always_inline and move it out of the
+instrumentation_begin/end() section.  It only calls __this_cpu_write()
+which is already safe to call in noinstr contexts.
