+Subject: alarmtimer: Fix argument order in alarm_timer_forward()
+
+From: Zhan Xusheng <zhanxusheng1024@gmail.com>
+
+commit 5d16467ae56343b9205caedf85e3a131e0914ad8 upstream.
+
+alarm_timer_forward() passes arguments to alarm_forward() in the wrong
+order:
+
+ alarm_forward(alarm, timr->it_interval, now);
+
+However, alarm_forward() is defined as:
+
+ u64 alarm_forward(struct alarm *alarm, ktime_t now, ktime_t interval);
+
+and uses the second argument as the current time:
+
+ delta = ktime_sub(now, alarm->node.expires);
+
+Passing the interval as "now" results in incorrect delta computation,
+which can lead to missed expirations or incorrect overrun accounting.
+
+This issue has been present since the introduction of
+alarm_timer_forward().
+
+Fix this by swapping the arguments.
+
+Fixes: e7561f1633ac ("alarmtimer: Implement forward callback")

+Subject: dmaengine: sh: rz-dmac: Move CHCTRL updates under spinlock
+
+From: Claudiu Beznea <claudiu.beznea@tuxon.dev>
+
+commit 89a8567d84bde88cb7cdbbac2ab2299c4f991490 upstream.
+
+Both rz_dmac_disable_hw() and rz_dmac_irq_handle_channel() update the
+CHCTRL register. To avoid concurrency issues when configuring
+functionalities exposed by this registers, take the virtual channel lock.
+All other CHCTRL updates were already protected by the same lock.
+
+Previously, rz_dmac_disable_hw() disabled and re-enabled local IRQs, before
+accessing CHCTRL registers but this does not ensure race-free access.
+Remove the local IRQ disable/enable code as well.

+From: Claudiu Beznea <claudiu.beznea@tuxon.dev>
+
+commit abb863e6213dc41a58ef8bb3289b7e77460dabf3 upstream.
+
+The driver lists (ld_free, ld_queue) are used in
+rz_dmac_free_chan_resources(), rz_dmac_terminate_all(),
+rz_dmac_issue_pending(), and rz_dmac_irq_handler_thread(), all under

+and rz_dmac_prep_dma_memcpy() as well to avoid concurrency issues, since
+these functions also check whether the lists are empty and update or
+remove list entries.

+Subject: jbd2: gracefully abort on checkpointing state corruptions
+
+From: Milos Nikic <nikic.milos@gmail.com>
+
+commit bac3190a8e79beff6ed221975e0c9b1b5f2a21da upstream.
+
+This patch targets two internal state machine invariants in checkpoint.c
+residing inside functions that natively return integer error codes.
+
+- In jbd2_cleanup_journal_tail(): A blocknr of 0 indicates a severely
+corrupted journal superblock. Replaced the J_ASSERT with a WARN_ON_ONCE
+and a graceful journal abort, returning -EFSCORRUPTED.
+
+- In jbd2_log_do_checkpoint(): Replaced the J_ASSERT_BH checking for
+an unexpected buffer_jwrite state. If the warning triggers, we
+explicitly drop the just-taken get_bh() reference and call __flush_batch()
+to safely clean up any previously queued buffers in the j_chkpt_bhs array,
+preventing a memory leak before returning -EFSCORRUPTED.

+Subject: KVM: x86/mmu: Drop/zap existing present SPTE even when creating an MMIO SPTE
+
+From: Sean Christopherson <seanjc@google.com>
+
+commit aad885e774966e97b675dfe928da164214a71605 upstream.
+
+When installing an emulated MMIO SPTE, do so *after* dropping/zapping the
+existing SPTE (if it's shadow-present). While commit a54aa15c6bda3 was
+right about it being impossible to convert a shadow-present SPTE to an
+MMIO SPTE due to a _guest_ write, it failed to account for writes to guest
+memory that are outside the scope of KVM.
+
+E.g. if host userspace modifies a shadowed gPTE to switch from a memslot
+to emulted MMIO and then the guest hits a relevant page fault, KVM will
+install the MMIO SPTE without first zapping the shadow-present SPTE.

+Subject: LoongArch: Workaround LS2K/LS7A GPU DMA hang bug
+
+From: Huacai Chen <chenhuacai@loongson.cn>
+
+commit 95db0c9f526d583634cddb2e5914718570fbac87 upstream.
+
+1. Hardware limitation: GPU, DC and VPU are typically PCI device 06.0,
+06.1 and 06.2. They share some hardware resources, so when configure the
+PCI 06.0 device BAR1, DMA memory access cannot be performed through this
+BAR, otherwise it will cause hardware abnormalities.
+
+2. In typical scenarios of reboot or S3/S4, DC access to memory through
+BAR is not prohibited, resulting in GPU DMA hangs.
+
+3. Workaround method: When configuring the 06.0 device BAR1, turn off
+the memory access of DC, GPU and VPU (via DC's CRTC registers).

+Subject: net: macb: Use dev_consume_skb_any() to free TX SKBs
+
+From: Kevin Hao <haokexin@gmail.com>
+
+commit 647b8a2fe474474704110db6bd07f7a139e621eb upstream.
+
+The napi_consume_skb() function is not intended to be called in an IRQ
+disabled context. However, after commit 6bc8a5098bf4 ("net: macb: Fix
+tx_ptr_lock locking"), the freeing of TX SKBs is performed with IRQs
+disabled. To resolve the following call trace, use dev_consume_skb_any()
+for freeing TX SKBs:

+Subject: scsi: ibmvfc: Fix OOB access in ibmvfc_discover_targets_done()
+
+From: Tyllis Xu <livelycarpet87@gmail.com>
+
+commit 61d099ac4a7a8fb11ebdb6e2ec8d77f38e77362f upstream.
+
+A malicious or compromised VIO server can return a num_written value in the
+discover targets MAD response that exceeds max_targets. This value is
+stored directly in vhost->num_targets without validation, and is then used
+as the loop bound in ibmvfc_alloc_targets() to index into disc_buf[], which
+is only allocated for max_targets entries. Indices at or beyond max_targets
+access kernel memory outside the DMA-coherent allocation. The
+out-of-bounds data is subsequently embedded in Implicit Logout and PLOGI
+MADs that are sent back to the VIO server, leaking kernel memory.
+
+Fix by clamping num_written to max_targets before storing it.

+Subject: xfs: fix ri_total validation in xlog_recover_attri_commit_pass2
+
+From: Long Li <leo.lilong@huawei.com>
+
+commit d72f2084e30966097c8eae762e31986a33c3c0ae upstream.
+
+The ri_total checks for SET/REPLACE operations are hardcoded to 3,
+but xfs_attri_item_size() only emits a value iovec when value_len > 0,
+so ri_total is 2 when value_len == 0.
+
+For PPTR_SET/PPTR_REMOVE/PPTR_REPLACE, value_len is validated by
+xfs_attri_validate() to be exactly sizeof(struct xfs_parent_rec) and
+is never zero, so their hardcoded checks remain correct.
+
+This problem may cause log recovery failures. The following script can be
+used to reproduce the problem:
+
+ #!/bin/bash
+ mkfs.xfs -f /dev/sda
+ mount /dev/sda /mnt/test/
+ touch /mnt/test/file
+ for i in {1..200}; do
+ attr -s "user.attr_$i" -V "value_$i" /mnt/test/file > /dev/null
+ done
+ echo 1 > /sys/fs/xfs/debug/larp
+ echo 1 > /sys/fs/xfs/sda/errortag/larp
+ attr -s "user.zero" -V "" /mnt/test/file
+ echo 0 > /sys/fs/xfs/sda/errortag/larp
+ umount /mnt/test
+ mount /dev/sda /mnt/test/ # mount failed
+
+Fix this by deriving the expected count dynamically as "2 + !!value_len"
+for SET/REPLACE operations.

+Subject: xfs: stop reclaim before pushing AIL during unmount
+
+From: Yuto Ohnuki <ytohnuki@amazon.com>
+
+commit 4f24a767e3d64a5f58c595b5c29b6063a201f1e3 upstream.
+
+The unmount sequence in xfs_unmount_flush_inodes() pushed the AIL while
+background reclaim and inodegc are still running. This is broken
+independently of any use-after-free issues - background reclaim and
+inodegc should not be running while the AIL is being pushed during
+unmount, as inodegc can dirty and insert inodes into the AIL during the
+flush, and background reclaim can race to abort and free dirty inodes.
+
+Reorder xfs_unmount_flush_inodes() to stop inodegc and cancel background
+reclaim before pushing the AIL. Stop inodegc before cancelling
+m_reclaim_work because the inodegc worker can re-queue m_reclaim_work
+via xfs_inodegc_set_reclaimable.
