[PATCH v6.6 0/2] x86/irq: Plug vector setup race

by Jinjie Ruan

There is a vector setup race, which overwrites the interrupt descriptor in the per CPU vector array resulting in a disfunctional device. CPU0 CPU1 interrupt is raised in APIC IRR but not handled free_irq() per_cpu(vector_irq, CPU1)[vector] = VECTOR_SHUTDOWN; request_irq() common_interrupt() d = this_cpu_read(vector_irq[vector]); per_cpu(vector_irq, CPU1)[vector] = desc; if (d == VECTOR_SHUTDOWN) this_cpu_write(vector_irq[vector], VECTOR_UNUSED); free_irq() cannot observe the pending vector in the CPU1 APIC as there is no way to query the remote CPUs APIC IRR. This requires that request_irq() uses the same vector/CPU as the one which was freed, but this also can be triggered by a spurious interrupt. Interestingly enough this problem managed to be hidden for more than a decade. Prevent this by reevaluating vector_irq under the vector lock, which is held by the interrupt activation code when vector_irq is updated.

However when that happens we just return from the function and ignore the remaining extrefs. The problem has been around since extrefs were introduced, in commit f186373fef00 ("btrfs: extended inode refs"), but it's hard to hit in practice because getting extref items encoding multiple extref requires getting a hash collision when computing the offset of the extref's key. The offset if computed like this: key.offset = btrfs_extref_hash(dir_ino, name->name, name->len); and btrfs_extref_hash() is just a wrapper around crc32c(). Fix this by moving to next iteration of the loop when we don't find the parent directory that an extref points to.

Re: Patch "can: ti_hecc: fix -Woverflow compiler warning" has been added to the 6.15-stable tree

This only silences a compiler warning. There are no actual bugs in the original code. This is why I did not put the Fixes tag. I am not against this being backported to stable but please note that this depends on the new BIT_U32() macro which where recently added in commit 5b572e8a9f3d ("bits: introduce fixed-type BIT_U*()") Link: https://git.kernel.org/torvalds/c/5b572e8a9f3d So, unless you also backport the above patch, this will not compile. The options are: 1. drop this patch (i.e. keep that benin -Woverflow in stable) 2. backport the new BIT_U*() macros and keep the patch as-is 3. modify the patch as below: mbx_mask = ~(u32)BIT(HECC_RX_LAST_MBOX); I'll let you decide what you prefer. That comment also applies to the other backports of that patch except for the 6.16.x branch which already has the BIT_U*() macros.

[PATCH rtw-next 1/2] wifi: rtw89: fix use-after-free in rtw89_core_tx_kick_off_and_wait()

by Fedor Pchelkin

There is a bug observed when rtw89_core_tx_kick_off_and_wait() tries to access already freed skb_data: BUG: KFENCE: use-after-free write in rtw89_core_tx_kick_off_and_wait drivers/net/wireless/realtek/rtw89/core.c:1110 CPU: 6 UID: 0 PID: 41377 Comm: kworker/u64:24 Not tainted 6.17.0-rc1+ #1 PREEMPT(lazy) Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS edk2-20250523-14.fc42 05/23/2025 Workqueue: events_unbound cfg80211_wiphy_work [cfg80211] Use-after-free write at 0x0000000020309d9d (in kfence-#251): rtw89_core_tx_kick_off_and_wait drivers/net/wireless/realtek/rtw89/core.c:1110 rtw89_core_scan_complete drivers/net/wireless/realtek/rtw89/core.c:5338 rtw89_hw_scan_complete_cb drivers/net/wireless/realtek/rtw89/fw.c:7979 rtw89_chanctx_proceed_cb drivers/net/wireless/realtek/rtw89/chan.c:3165 rtw89_chanctx_proceed drivers/net/wireless/realtek/rtw89/chan.h:141 rtw89_hw_scan_complete drivers/net/wireless/realtek/rtw89/fw.c:8012 rtw89_mac_c2h_scanofld_rsp drivers/net/wireless/realtek/rtw89/mac.c:5059 rtw89_fw_c2h_work drivers/net/wireless/realtek/rtw89/fw.c:6758 process_one_work kernel/workqueue.c:3241 worker_thread kernel/workqueue.c:3400 kthread kernel/kthread.c:463 ret_from_fork arch/x86/kernel/process.c:154 ret_from_fork_asm arch/x86/entry/entry_64.S:258 kfence-#251: 0x0000000056e2393d-0x000000009943cb62, size=232, cache=skbuff_head_cache allocated by task 41377 on cpu 6 at 77869.159548s (0.009551s ago): __alloc_skb net/core/skbuff.c:659 __netdev_alloc_skb net/core/skbuff.c:734 ieee80211_nullfunc_get net/mac80211/tx.c:5844 rtw89_core_send_nullfunc drivers/net/wireless/realtek/rtw89/core.c:3431 rtw89_core_scan_complete drivers/net/wireless/realtek/rtw89/core.c:5338 rtw89_hw_scan_complete_cb drivers/net/wireless/realtek/rtw89/fw.c:7979 rtw89_chanctx_proceed_cb drivers/net/wireless/realtek/rtw89/chan.c:3165 rtw89_chanctx_proceed drivers/net/wireless/realtek/rtw89/chan.c:3194 rtw89_hw_scan_complete drivers/net/wireless/realtek/rtw89/fw.c:8012 rtw89_mac_c2h_scanofld_rsp drivers/net/wireless/realtek/rtw89/mac.c:5059 rtw89_fw_c2h_work drivers/net/wireless/realtek/rtw89/fw.c:6758 process_one_work kernel/workqueue.c:3241 worker_thread kernel/workqueue.c:3400 kthread kernel/kthread.c:463 ret_from_fork arch/x86/kernel/process.c:154 ret_from_fork_asm arch/x86/entry/entry_64.S:258 freed by task 1045 on cpu 9 at 77869.168393s (0.001557s ago): ieee80211_tx_status_skb net/mac80211/status.c:1117 rtw89_pci_release_txwd_skb drivers/net/wireless/realtek/rtw89/pci.c:564 rtw89_pci_release_tx_skbs.isra.0 drivers/net/wireless/realtek/rtw89/pci.c:651 rtw89_pci_release_tx drivers/net/wireless/realtek/rtw89/pci.c:676 rtw89_pci_napi_poll drivers/net/wireless/realtek/rtw89/pci.c:4238 __napi_poll net/core/dev.c:7495 net_rx_action net/core/dev.c:7557 net/core/dev.c:7684 handle_softirqs kernel/softirq.c:580 do_softirq.part.0 kernel/softirq.c:480 __local_bh_enable_ip kernel/softirq.c:407 rtw89_pci_interrupt_threadfn drivers/net/wireless/realtek/rtw89/pci.c:927 irq_thread_fn kernel/irq/manage.c:1133 irq_thread kernel/irq/manage.c:1257 kthread kernel/kthread.c:463 ret_from_fork arch/x86/kernel/process.c:154 ret_from_fork_asm arch/x86/entry/entry_64.S:258 It is a consequence of a race between the waiting and the signalling side of the completion: Thread 1 Thread 2 rtw89_core_tx_kick_off_and_wait() rcu_assign_pointer(skb_data->wait, wait) /* start waiting */ wait_for_completion_timeout() rtw89_pci_tx_status() rtw89_core_tx_wait_complete() rcu_read_lock() /* signals completion and * proceeds further */ complete(&wait->completion) rcu_read_unlock() ... /* frees skb_data */ ieee80211_tx_status_ni() /* returns (exit status doesn't matter) */ wait_for_completion_timeout() ... /* accesses the already freed skb_data */ rcu_assign_pointer(skb_data->wait, NULL) The signalling side might proceed and free the underlying skb even before the waiting side is fully awoken and run to execution. RCU synchronization here would work well if the signalling side didn't go on and release skb on its own. Thus the waiting side should be told somehow about what is happening on the completion side. It seems the only correct way is to use standard locking primitives with owner tracking, like was originally published in one [1] of the versions of the patch mentioned in Fixes.

Fixes: 1ae5ca615285 ("wifi: rtw89: add function to wait for completion of TX skbs") Cc: stable(a)vger.kernel.org Signed-off-by: Fedor Pchelkin <pchelkin(a)ispras.ru> --- The bug is tricky because the waiter-completer interaction isn't simple here. I've tried to come up with something that wouldn't require taking additional locks at rtw89_core_tx_wait_complete() but these ideas don't eliminate the possible race entirely, to my mind. Though one solution that _works_ currently is to get rid of 'struct rtw89_tx_wait_info' and replace it with the only field it is used for - 'bool tx_done'. Then it can be stored at 'struct ieee80211_tx_info::status::status_driver_data' directly without the need for allocating an extra dynamic object and tracking its lifecycle. I didn't post this since then the structure won't be expandable for new fields and that's probably the reason for why it wasn't done in this manner initially. drivers/net/wireless/realtek/rtw89/core.c | 15 ++++++++--- drivers/net/wireless/realtek/rtw89/core.h | 32 ++++++++++++++--------- drivers/net/wireless/realtek/rtw89/pci.c | 6 +++-- 3 files changed, 36 insertions(+), 17 deletions(-) diff --git a/drivers/net/wireless/realtek/rtw89/core.c b/drivers/net/wireless/realtek/rtw89/core.c index 57590f5577a3..826540319027 100644 --- a/drivers/net/wireless/realtek/rtw89/core.c +++ b/drivers/net/wireless/realtek/rtw89/core.c @@ -1088,6 +1088,7 @@ int rtw89_core_tx_kick_off_and_wait(struct rtw89_dev *rtwdev, struct sk_buff *sk struct rtw89_tx_skb_data *skb_data = RTW89_TX_SKB_CB(skb); struct rtw89_tx_wait_info *wait; unsigned long time_left; + bool free_wait = true; int ret = 0; wait = kzalloc(sizeof(*wait), GFP_KERNEL); @@ -1097,7 +1098,8 @@ int rtw89_core_tx_kick_off_and_wait(struct rtw89_dev *rtwdev, struct sk_buff *sk } init_completion(&wait->completion); - rcu_assign_pointer(skb_data->wait, wait); + spin_lock_init(&wait->owner_lock); + skb_data->wait = wait; rtw89_core_tx_kick_off(rtwdev, qsel); time_left = wait_for_completion_timeout(&wait->completion, @@ -1107,8 +1109,15 @@ int rtw89_core_tx_kick_off_and_wait(struct rtw89_dev *rtwdev, struct sk_buff *sk else if (!wait->tx_done) ret = -EAGAIN; - rcu_assign_pointer(skb_data->wait, NULL); - kfree_rcu(wait, rcu_head); + spin_lock_bh(&wait->owner_lock); + if (time_left == 0 && wait->owner != RTW89_TX_WAIT_OWNER_WAIT) { + free_wait = false; + wait->owner = RTW89_TX_WAIT_OWNER_COMPLETE; + } + spin_unlock_bh(&wait->owner_lock); + + if (free_wait) + kfree(wait); return ret; } diff --git a/drivers/net/wireless/realtek/rtw89/core.h b/drivers/net/wireless/realtek/rtw89/core.h index 43e10278e14d..0117f24324d5 100644 --- a/drivers/net/wireless/realtek/rtw89/core.h +++ b/drivers/net/wireless/realtek/rtw89/core.h @@ -3506,14 +3506,21 @@ struct rtw89_phy_rate_pattern { bool enable; }; +enum rtw89_tx_wait_owner { + RTW89_TX_WAIT_OWNER_UNDET, + RTW89_TX_WAIT_OWNER_WAIT, + RTW89_TX_WAIT_OWNER_COMPLETE, +}; + struct rtw89_tx_wait_info { - struct rcu_head rcu_head; struct completion completion; bool tx_done; + spinlock_t owner_lock; /* lock to access owner */ + enum rtw89_tx_wait_owner owner; }; struct rtw89_tx_skb_data { - struct rtw89_tx_wait_info __rcu *wait; + struct rtw89_tx_wait_info *wait; u8 hci_priv[]; }; @@ -7259,22 +7266,23 @@ static inline struct sk_buff *rtw89_alloc_skb_for_rx(struct rtw89_dev *rtwdev, } static inline void rtw89_core_tx_wait_complete(struct rtw89_dev *rtwdev, - struct rtw89_tx_skb_data *skb_data, + struct rtw89_tx_wait_info *wait, bool tx_done) { - struct rtw89_tx_wait_info *wait; - - rcu_read_lock(); - - wait = rcu_dereference(skb_data->wait); - if (!wait) - goto out; + bool free_wait = true; wait->tx_done = tx_done; + + spin_lock_bh(&wait->owner_lock); complete(&wait->completion); + if (wait->owner != RTW89_TX_WAIT_OWNER_COMPLETE) { + free_wait = false; + wait->owner = RTW89_TX_WAIT_OWNER_WAIT; + } + spin_unlock_bh(&wait->owner_lock); -out: - rcu_read_unlock(); + if (free_wait) + kfree(wait); } static inline bool rtw89_is_mlo_1_1(struct rtw89_dev *rtwdev) diff --git a/drivers/net/wireless/realtek/rtw89/pci.c b/drivers/net/wireless/realtek/rtw89/pci.c index a669f2f843aa..d9d4558b21ea 100644 --- a/drivers/net/wireless/realtek/rtw89/pci.c +++ b/drivers/net/wireless/realtek/rtw89/pci.c @@ -462,9 +462,11 @@ static void rtw89_pci_tx_status(struct rtw89_dev *rtwdev, struct sk_buff *skb, u8 tx_status) { struct rtw89_tx_skb_data *skb_data = RTW89_TX_SKB_CB(skb); + struct rtw89_tx_wait_info *wait = skb_data->wait; struct ieee80211_tx_info *info; - rtw89_core_tx_wait_complete(rtwdev, skb_data, tx_status == RTW89_TX_DONE); + if (wait) + rtw89_core_tx_wait_complete(rtwdev, wait, tx_status == RTW89_TX_DONE); info = IEEE80211_SKB_CB(skb); ieee80211_tx_info_clear_status(info); @@ -1387,7 +1389,7 @@ static int rtw89_pci_txwd_submit(struct rtw89_dev *rtwdev, } tx_data->dma = dma; - rcu_assign_pointer(skb_data->wait, NULL); + skb_data->wait = NULL; txwp_len = sizeof(*txwp_info); txwd_len = chip->txwd_body_size; -- 2.50.1

[PATCH] btrfs: do more strict compressed read merge check

[BUG] When running test case generic/457, there is a chance to hit the following error, with 64K page size and 4K btrfs block size, and "compress=zstd" mount option: FSTYP -- btrfs PLATFORM -- Linux/aarch64 btrfs-aarch64 6.17.0-rc2-custom+ #129 SMP PREEMPT_DYNAMIC Wed Aug 20 18:52:51 ACST 2025 MKFS_OPTIONS -- -s 4k /dev/mapper/test-scratch1 MOUNT_OPTIONS -- -o compress=zstd /dev/mapper/test-scratch1 /mnt/scratch generic/457 2s ...

There is a much smaller reproducer based on that test case, which I mainly used to debug the bug: workload() { mkfs.btrfs -f $dev > /dev/null dmesg -C trace-cmd clear mount -o compress=zstd $dev $mnt xfs_io -f -c "pwrite -S 0xff 0 256K" -c "sync" $mnt/base > /dev/null cp --reflink=always -p -f $mnt/base $mnt/file $fsx -N 4 -d -k -S 3746842 $mnt/file if [ $? -ne 0 ]; then echo "!!!

CSUM MISMATCH !!!" fail fi } This seed value will cause 100% reproducible csum mismatch after a mount cycle. [CAUSE] With extra debug trace_printk(), the following sequence can explain the root cause: fsx-3900290 [002] ..... 161696.160966: btrfs_submit_compressed_read: r/i=5/258 file_off=131072 em start=126976 len=16384 The "r/i" is showing the root id and the ino number. In this case, my minimal reproducer is indeed using inode 258 of subvolume 5, and that's the inode with changing contents. The above trace is from the function btrfs_submit_compressed_read(), triggered by fsx to read the folio at file offset 128K. Notice that the extent map, it's at offset 124K, with a length of 16K. This means the extent map only covers the first 12K (3 blocks) of the folio 128K. fsx-3900290 [002] ..... 161696.160969: trace_dump_cb: btrfs_submit_compressed_read, r/i=5/258 file off start=131072 len=65536 bi_size=65536 This is the line I used to dump the basic info of a bbio, which shows the bi_size is 64K, aka covering the whole 64K folio at file offset 128K. But remember, the extent map only covers 3 blocks, definitely not enough to cover the whole 64K folio at 128K file offset. kworker/u19:1-3748349 [002] ..... 161696.161154: btrfs_decompress_buf2page: r/i=5/258 file_off=131072 copy_len=4096 content=ffff kworker/u19:1-3748349 [002] ..... 161696.161155: btrfs_decompress_buf2page: r/i=5/258 file_off=135168 copy_len=4096 content=ffff kworker/u19:1-3748349 [002] ..... 161696.161156: btrfs_decompress_buf2page: r/i=5/258 file_off=139264 copy_len=4096 content=ffff kworker/u19:1-3748349 [002] ..... 161696.161157: btrfs_decompress_buf2page: r/i=5/258 file_off=143360 copy_len=4096 content=ffff The above lines show that btrfs_decompress_buf2page() called by zstd decompress code is copying the decompressed content into the filemap. But notice that, the last line is already beyond the extent map range. Furthermore, there are no more compressed content copy, as the compressed bio only has the extent map to cover the first 3 blocks (the 4th block copy is already incorrect). kworker/u19:1-3748349 [002] ..... 161696.161161: trace_dump_cb: r/i=5/258 file_pos=131072 content=ffff kworker/u19:1-3748349 [002] ..... 161696.161161: trace_dump_cb: r/i=5/258 file_pos=135168 content=ffff kworker/u19:1-3748349 [002] ..... 161696.161162: trace_dump_cb: r/i=5/258 file_pos=139264 content=ffff kworker/u19:1-3748349 [002] ..... 161696.161162: trace_dump_cb: r/i=5/258 file_pos=143360 content=ffff kworker/u19:1-3748349 [002] ..... 161696.161162: trace_dump_cb: r/i=5/258 file_pos=147456 content=0000 This is the extra dumpping of the compressed bio, after file offset 140K (143360), the content is all zero, which is incorrect. The zero is there because we didn't copy anything into the folio. The root cause of the corruption is, we are submitting a compressed read for a whole folio, but the extent map we get only covers the first 3 blocks, meaning the compressed read path is merging reads that shouldn't be merged. The involved file extents are: item 19 key (258 EXTENT_DATA 126976) itemoff 15143 itemsize 53 generation 9 type 1 (regular) extent data disk byte 13635584 nr 4096 extent data offset 110592 nr 16384 ram 131072 extent compression 3 (zstd) item 20 key (258 EXTENT_DATA 143360) itemoff 15090 itemsize 53 generation 9 type 1 (regular) extent data disk byte 13635584 nr 4096 extent data offset 12288 nr 24576 ram 131072 extent compression 3 (zstd) Note that, both extents at 124K and 140K are pointing to the same compressed extent, but with different offset. This means, we reads of range [124K, 140K) and [140K, 165K) should not be merged. But read merge check function, btrfs_bio_is_contig(), is only checking the disk_bytenr of two compressed reads, as there are not enough info like the involved extent maps to do more comprehensive checks, resulting the incorrect compressed read. Unfortunately this is a long existing bug, way before subpage block size support. But subpage block size support (and experimental large folio support) makes it much easier to detect. If block size equals page size, regular page read will only read one block each time, thus no extent map sharing nor merge. (This means for bs == ps cases, it's still possible to hit the bug with readahead, just we don't have test coverage with content verification for readahead) [FIX] Save the last hit compressed extent map into btrfs_bio_ctrl, and check if the last compressed extent map is completely the same as the current one. If not, force submitting the current bio, so that the read will never be merged. And after submitting a bio, clear btrfs_bio_ctrl::last_compressed_em to avoid incorrect detection.

[PATCH 5.15.y 1/2] scsi: ufs: ufs-pci: Fix hibernate state transition for Intel MTL-like host controllers

by Adrian Hunter

From: Archana Patni <archana.patni(a)intel.com> commit 4428ddea832cfdb63e476eb2e5c8feb5d36057fe upstream. UFSHCD core disables the UIC completion interrupt when issuing UIC hibernation commands, and re-enables it afterwards if it was enabled to start with, refer ufshcd_uic_pwr_ctrl(). For Intel MTL-like host controllers, accessing the register to re-enable the interrupt disrupts the state transition. Use hibern8_notify variant operation to disable the interrupt during the entire hibernation, thereby preventing the disruption.

[PATCH v2] iommu/virtio: Make instance lookup robust

by Robin Murphy

Much like arm-smmu in commit 7d835134d4e1 ("iommu/arm-smmu: Make instance lookup robust"), virtio-iommu appears to have the same issue where iommu_device_register() makes the IOMMU instance visible to other API callers (including itself) straight away, but internally the instance isn't ready to recognise itself for viommu_probe_device() to work correctly until after viommu_probe() has returned. This matters a lot more now that bus_iommu_probe() has the DT/VIOT knowledge to probe client devices the way that was always intended. Tweak the lookup and initialisation in much the same way as for arm-smmu, to ensure that what we register is functional and ready to go.
