[PATCH OLK-6.6] xfs: Fix data overflow in xfs_mod_fdblocks()
by Zizhi Wo 03 Dec '24

03 Dec '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB7V02 -------------------------------- If the xfs reserve block related ioctl takes a large input value, the input reserved size is still assigned to mp->m_resblks in xfs_reserve_blocks() even if the requested size is larger than the total free size in the filesystem. This is because the subsequent xfs_mod_fdblocks() will handle the adjustment. However, in the current code, xfs_mod_fdblocks() calculates mp->m_resblks - mp->m_resblks_avail and casts the result to a long long type, while both mp->m_resblks and mp->m_resblks_avail are of type unsigned long long. If the difference between these two values is very large, and the most significant bit (MSB) is set to 1 (indicating a large unsigned value), the result of the cast becomes a large negative value. This causes mp->m_fdblocks to be updated to a very large value.

[PATCH OLK-5.10] xfs: Fix data overflow in xfs_mod_fdblocks()
by Zizhi Wo 03 Dec '24

03 Dec '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB7V02 -------------------------------- If the xfs reserve block related ioctl takes a large input value, the input reserved size is still assigned to mp->m_resblks in xfs_reserve_blocks() even if the requested size is larger than the total free size in the filesystem. This is because the subsequent xfs_mod_fdblocks() will handle the adjustment. However, in the current code, xfs_mod_fdblocks() calculates mp->m_resblks - mp->m_resblks_avail and casts the result to a long long type, while both mp->m_resblks and mp->m_resblks_avail are of type unsigned long long. If the difference between these two values is very large, and the most significant bit (MSB) is set to 1 (indicating a large unsigned value), the result of the cast becomes a large negative value. This causes mp->m_fdblocks to be updated to a very large value. As a result, xfs will incorrectly determine that there is always free space during foreground writes, while background writebacks may fail due to lack of space. Modify the relevant data types in xfs_mod_fdblocks() to address this issue.

[PATCH OLK-6.6 0/1] Backport fs optimizing patch from mainline
by Zheng Zengkai 03 Dec '24

03 Dec '24

64 bits in open_fds are mapped to a common bit in full_fds_bits. It is very likely that a bit in full_fds_bits has been cleared before in __clear_open_fds()'s operation. Check the clear bit in full_fds_bits before clearing to avoid unnecessary write and cache bouncing. See commit fc90888d07b8 ("vfs: conditionally clear close-on-exec flag") for a similar optimization. take stock kernel with patch 1 as baseline, it improves pts/blogbench-1.1.0 read for 13%, and write for 5% on Intel ICX 160 cores configuration with v6.10-rc7.

[PATCH OLK-6.6] ext4: show the default enabled prefetch_block_bitmaps option

mainline inclusion from mainline-v6.13-rc1 commit fdfa648ab9393de8c1be21cad17c17bdced3a68a category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB8IC8 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- After commit 21175ca434c5 ("ext4: make prefetch_block_bitmaps default"), we enable 'prefetch_block_bitmaps' by default, but this is not shown in the '/proc/fs/ext4/sdx/options' procfs interface. This makes it impossible to distinguish whether the feature is enabled by default or not, so 'prefetch_block_bitmaps' is shown in the 'options' procfs interface when prefetch_block_bitmaps is enabled by default. This makes it easy to notice changes to the default mount options between versions through the '/proc/fs/ext4/sdx/options' procfs interface.

[PATCH OLK-5.10] iommu/vt-d: Fix potential lockup if qi_submit_sync called with 0 count
by Tirui Yin 03 Dec '24

From: Sanjay K Kumar <sanjay.k.kumar(a)intel.com> stable inclusion from stable-v5.10.227 commit de9e7f68762585f7532de8a06de9485bf39dbd38 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYRAV CVE: CVE-2024-49993 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 3cf74230c139f208b7fb313ae0054386eee31a81 ] If qi_submit_sync() is invoked with 0 invalidation descriptors (for instance, for DMA draining purposes), we can run into a bug where a submitting thread fails to detect the completion of invalidation_wait. Subsequently, this led to a soft lockup. Currently, there is no impact by this bug on the existing users because no callers are submitting invalidations with 0 descriptors. This fix will enable future users (such as DMA drain) calling qi_submit_sync() with 0 count. Suppose thread T1 invokes qi_submit_sync() with non-zero descriptors, while concurrently, thread T2 calls qi_submit_sync() with zero descriptors. Both threads then enter a while loop, waiting for their respective descriptors to complete. T1 detects its completion (i.e., T1's invalidation_wait status changes to QI_DONE by HW) and proceeds to call reclaim_free_desc() to reclaim all descriptors, potentially including adjacent ones of other threads that are also marked as QI_DONE. During this time, while T2 is waiting to acquire the qi->q_lock, the IOMMU hardware may complete the invalidation for T2, setting its status to QI_DONE. However, if T1's execution of reclaim_free_desc() frees T2's invalidation_wait descriptor and changes its status to QI_FREE, T2 will not observe the QI_DONE status for its invalidation_wait and will indefinitely remain stuck. This soft lockup does not occur when only non-zero descriptors are submitted.In such cases, invalidation descriptors are interspersed among wait descriptors with the status QI_IN_USE, acting as barriers. These barriers prevent the reclaim code from mistakenly freeing descriptors belonging to other submitters. Considered the following example timeline: T1 T2 ======================================== ID1 WD1 while(WD1!=QI_DONE) unlock lock WD1=QI_DONE* WD2 while(WD2!=QI_DONE) unlock lock WD1==QI_DONE? ID1=QI_DONE WD2=DONE* reclaim() ID1=FREE WD1=FREE WD2=FREE unlock soft lockup! T2 never sees QI_DONE in WD2 Where: ID = invalidation descriptor WD = wait descriptor * Written by hardware The root of the problem is that the descriptor status QI_DONE flag is used for two conflicting purposes: 1. signal a descriptor is ready for reclaim (to be freed) 2. signal by the hardware that a wait descriptor is complete The solution (in this patch) is state separation by using QI_FREE flag for #1. Once a thread's invalidation descriptors are complete, their status would be set to QI_FREE. The reclaim_free_desc() function would then only free descriptors marked as QI_FREE instead of those marked as QI_DONE. This change ensures that T2 (from the previous example) will correctly observe the completion of its invalidation_wait (marked as QI_DONE).

[PATCH OLK-6.6] afs: Fix lock recursion
by Yifan Qiao 03 Dec '24

03 Dec '24

From: David Howells <dhowells(a)redhat.com> mainline inclusion from mainline-v6.12-rc5 commit 610a79ffea02102899a1373fe226d949944a7ed6 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB67YK CVE: CVE-2024-53090 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- afs_wake_up_async_call() can incur lock recursion. The problem is that it is called from AF_RXRPC whilst holding the ->notify_lock, but it tries to take a ref on the afs_call struct in order to pass it to a work queue - but if the afs_call is already queued, we then have an extraneous ref that must be put... calling afs_put_call() may call back down into AF_RXRPC through rxrpc_kernel_shutdown_call(), however, which might try taking the ->notify_lock again. This case isn't very common, however, so defer it to a workqueue. The oops looks something like: BUG: spinlock recursion on CPU#0, krxrpcio/7001/1646 lock: 0xffff888141399b30, .magic: dead4ead, .owner: krxrpcio/7001/1646, .owner_cpu: 0 CPU: 0 UID: 0 PID: 1646 Comm: krxrpcio/7001 Not tainted 6.12.0-rc2-build3+ #4351 Hardware name: ASUS All Series/H97-PLUS, BIOS 2306 10/09/2014 Call Trace: <TASK> dump_stack_lvl+0x47/0x70 do_raw_spin_lock+0x3c/0x90 rxrpc_kernel_shutdown_call+0x83/0xb0 afs_put_call+0xd7/0x180 rxrpc_notify_socket+0xa0/0x190 rxrpc_input_split_jumbo+0x198/0x1d0 rxrpc_input_data+0x14b/0x1e0 ? rxrpc_input_call_packet+0xc2/0x1f0 rxrpc_input_call_event+0xad/0x6b0 rxrpc_input_packet_on_conn+0x1e1/0x210 rxrpc_input_packet+0x3f2/0x4d0 rxrpc_io_thread+0x243/0x410 ? __pfx_rxrpc_io_thread+0x10/0x10 kthread+0xcf/0xe0 ? __pfx_kthread+0x10/0x10 ret_from_fork+0x24/0x40 ? __pfx_kthread+0x10/0x10 ret_from_fork_asm+0x1a/0x30 </TASK> Signed-off-by: David Howells <dhowells(a)redhat.com> Link: https://lore.kernel.org/r/1394602.1729162732@warthog.procyon.org.uk cc: Marc Dionne <marc.dionne(a)auristor.com> cc: linux-afs(a)lists.infradead.org cc: linux-fsdevel(a)vger.kernel.org Signed-off-by: Christian Brauner <brauner(a)kernel.org> Conflicts: fs/afs/internal.h fs/afs/rxrpc.c [Context differences and the patchset(afs: Fix probe handling, server rotation and RO volume callback handling) is not merged yet.] Signed-off-by: Yifan Qiao <qiaoyifan4(a)huawei.com> --- fs/afs/internal.h | 2 ++ fs/afs/rxrpc.c | 81 +++++++++++++++++++++++++++++++++-------------- 2 files changed, 60 insertions(+), 23 deletions(-) diff --git a/fs/afs/internal.h b/fs/afs/internal.h index 8dcc09cf0adb..89b5464ca8ef 100644 --- a/fs/afs/internal.h +++ b/fs/afs/internal.h @@ -100,6 +100,7 @@ struct afs_call { wait_queue_head_t waitq;

[PATCH OLK-6.6 v2 0/5] Optimize functions like get_user and put_user
by Ze Zuo 02 Dec '24

02 Dec '24

Due to the performance degradation of the lsmem command on the ARM architecture, unsafe_copy_to_user, unsafe_put_user, and unsafe_get_user have been introduced to bypass the usercopy checks. This optimizes the data exchange between user space and kernel space, thereby improving performance. v1->v2: -- Some commit message cleanup on patch 5. Linus Torvalds (2): arm64: start using 'asm goto' for get_user() when available arm64: start using 'asm goto' for put_user() Mark Rutland (2): init/Kconfig: remove CONFIG_GCC_ASM_GOTO_OUTPUT_WORKAROUND arm64: uaccess: correct thinko in __get_mem_asm() Ze Zuo (1): openeuler_defconfig: remove GCC_ASM_GOTO_OUTPUT_WORKAROUND for x86 and arm64 arch/arm64/Kconfig | 4 + arch/arm64/configs/openeuler_defconfig | 1 - arch/arm64/include/asm/asm-extable.h | 3 + arch/arm64/include/asm/uaccess.h | 169 ++++++++++++++++++------- arch/arm64/kernel/mte.c | 12 +- arch/x86/configs/openeuler_defconfig | 1 - include/linux/compiler-gcc.h | 20 --- init/Kconfig | 22 ++-- 8 files changed, 147 insertions(+), 85 deletions(-) -- 2.25.1

[PATCH OLK-6.6 0/5] virtio-fs: introduce multi-queue support
by Shuai Wu 02 Dec '24

02 Dec '24

Patch1 to patch3 are the interfaces for exporting virtio-fs tags from sysfs during multi-queue modification. patches 4 to 5 add multi-queue support to the virtio-fs driver to enhance performance. Although the multi-queue feature has been in the virtio-fs specification since its inception, the current implementation in the Linux kernel creates multiple queues but enqueues requests to only the first request queue. Shuai Wu (5): virtiofs: export filesystem tags through sysfs virtiofs: emit uevents on filesystem events virtiofs: include a newline in sysfs tag virtio-fs: limit number of request queues virtio-fs: add multi-queue support Documentation/ABI/testing/sysfs-fs-virtiofs | 11 ++ fs/fuse/virtio_fs.c | 200 +++++++++++++++++--- 2 files changed, 181 insertions(+), 30 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-fs-virtiofs -- 2.33.0

[PATCH openEuler-22.03-LTS-SP1] xfs: Fix data overflow in xfs_mod_fdblocks()
by Zizhi Wo 02 Dec '24

02 Dec '24

Offering: HULK hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB7V02 -------------------------------- If the xfs reserve block related ioctl takes a large input value, the input reserved size is still assigned to mp->m_resblks in xfs_reserve_blocks() even if the requested size is larger than the total free size in the filesystem. This is because the subsequent xfs_mod_fdblocks() will handle the adjustment. However, in the current code, xfs_mod_fdblocks() calculates mp->m_resblks - mp->m_resblks_avail and casts the result to a long long type, while both mp->m_resblks and mp->m_resblks_avail are of type unsigned long long. If the difference between these two values is very large, and the most significant bit (MSB) is set to 1 (indicating a large unsigned value), the result of the cast becomes a large negative value. This causes mp->m_fdblocks to be updated to a very large value. As a result, xfs will incorrectly determine that there is always free space during foreground writes, while background writebacks may fail due to lack of space. Modify the relevant data types in xfs_mod_fdblocks() to address this issue.

[PATCH OLK-6.6] xfs: split xfs_mod_freecounter
by Zizhi Wo 02 Dec '24

02 Dec '24

From: Christoph Hellwig <hch(a)lst.de> mainline inclusion from mainline-v6.10-rc1 commit f30f656e25eb72c4309e76b16fa45062e183a2ee category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB7V02 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- xfs_mod_freecounter has two entirely separate code paths for adding or subtracting from the free counters. Only the subtract case looks at the rsvd flag and can return an error. Split xfs_mod_freecounter into separate helpers for subtracting or adding the freecounter, and remove all the impossible to reach error handling for the addition case. Fixes: 0d485ada404b ("xfs: use generic percpu counters for free block counter") Signed-off-by: Christoph Hellwig <hch(a)lst.de> Reviewed-by: Dave Chinner <dchinner(a)redhat.com> Reviewed-by: "Darrick J.

[PATCH OLK-5.10] xfs: Fix data overflow in xfs_mod_fdblocks()
by Zizhi Wo 02 Dec '24

02 Dec '24

Offering: HULK hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB7V02 -------------------------------- If the xfs reserve block related ioctl takes a large input value, the input reserved size is still assigned to mp->m_resblks in xfs_reserve_blocks() even if the requested size is larger than the total free size in the filesystem. This is because the subsequent xfs_mod_fdblocks() will handle the adjustment. However, in the current code, xfs_mod_fdblocks() calculates mp->m_resblks - mp->m_resblks_avail and casts the result to a long long type, while both mp->m_resblks and mp->m_resblks_avail are of type unsigned long long. If the difference between these two values is very large, and the most significant bit (MSB) is set to 1 (indicating a large unsigned value), the result of the cast becomes a large negative value. This causes mp->m_fdblocks to be updated to a very large value. As a result, xfs will incorrectly determine that there is always free space during foreground writes, while background writebacks may fail due to lack of space. Modify the relevant data types in xfs_mod_fdblocks() to address this issue.
