[PATCH openEuler-25.03 v3 0/4] Add TrIO support in EROFS
by Hongbo Li 26 Feb '25

26 Feb '25

TrIO can accelerate the cold start of containers during on-demand loading. It aggregates the read I/O operations required for container runtime during the first container launch. In the following startups, TrIO pulls the necessary I/O data to the container node in a single large I/O operation and uses this I/O information to construct the runtime rootfs. By improving the efficiency of network I/O, TrIO speeds up container startup in on-demand loading scenarios. TrIO consists of both kernel-space and user-space code. The kernel-space code has been adapted at the overlayfs layer, introducing the CONFIG_EROFS_TRIO configuration to provide isolation. The user-space code requires adaptation by the user, and detailed usage methods are introduced in the tools/trio/README.md section. Patches 1~2 correspond to the kernel adaptations, while patches 3~4 are the scripts and best practices that TrIO relies on for its operation. v3: - Obtain and keep the trio_object in open. - Only close readahead in trio case.

[PATCH openEuler-25.03 v3 0/4] Add TrIO support in EROFS
by Hongbo Li 26 Feb '25

26 Feb '25

TrIO can accelerate the cold start of containers during on-demand loading. It aggregates the read I/O operations required for container runtime during the first container launch. In the following startups, TrIO pulls the necessary I/O data to the container node in a single large I/O operation and uses this I/O information to construct the runtime rootfs. By improving the efficiency of network I/O, TrIO speeds up container startup in on-demand loading scenarios. TrIO consists of both kernel-space and user-space code. The kernel-space code has been adapted at the overlayfs layer, introducing the CONFIG_EROFS_TRIO configuration to provide isolation. The user-space code requires adaptation by the user, and detailed usage methods are introduced in the tools/trio/README.md section. Patches 1~2 correspond to the kernel adaptations, while patches 3~4 are the scripts and best practices that TrIO relies on for its operation. v3: - Obtain and keep the trio_object in open. - Only close readahead in trio case.

[PATCH v4 openEuler-25.03 00/20] mm: arm64: Add kernel replication feature
by Denis Darvish 25 Feb '25

25 Feb '25

This patchset implements initial support of kernel text and rodata replication for AArch64. openEuler 25.03 is used as a baseline. Current implementation supports next functionality: 1. Replicated kernel text and rodata per-NUMA node 2. Vmalloc is able to work with replicated areas, so kernel modules text and rodata also replicated during modules loading stage. 3. BPF handlers are not replicated by default, but this can be easily done by using existent APIs. 4. KPROBES, KGDB and all functionality that depends on kernel text patching work without any limitation. 5. KPTI, KASLR, and KASAN fully supported. 6. Replicates parts of translation table related to replicated text and rodata. 7. 4K and 64K pages are supported. Translation tables synchronization is necessary only in several special cases: 1. Kernel boot 2. Modules deployment 3. Any allocation in user space that require new PUD/P4D In current design mutable kernel data modifications don't require synchronization between translation tables due to on 64-bit platforms all physical memory already mapped in kernel space and this mapping is persistent. In user space the translation tables synchronizations are quite rare due to the only case is new PUD/P4D allocation. At the current stage only the PGD layer is replicated for the user space. Please refer to the next pics.

[PATCH openEuler-1.0-LTS] cifs: Prevent NULL pointer dereference caused by cifs_sb->rsize is 0
by Wang Zhaolong 25 Feb '25

25 Feb '25

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBO3FG CVE: NA -------------------------------- When cifs_sb->rsize is 0, cifs_send_async_read() fails to allocate the pages array using iov_iter_get_pages_alloc(), resulting in data->pages being NULL. This eventually triggers a NULL pointer dereference in the callback function uncached_fill_pages(). cifs_sb->rsize is set to the minimum value between SMB3_DEFAULT_IOSIZE and server->max_read. SMB3_DEFAULT_IOSIZE is 4MB. There are two reasons that cause cifs_sb->rsize to be 0: 1. During the negotiation process, if the server returns an rsp->MaxReadSize of 0, server->max_read is assigned 0. And the calculated value of cifs_sb->rsize becomes 0. 2. In the cifsd thread, if cifs_reconnect() is invoked, server->max_read is set to 0. Prior to the completion of the reconnection process, the calculated value of cifs_sb->rsize becomes 0. It is important to note that cifs_sb->rsize is only set to 0 during the mount phase. Therefore, a straightforward approach to prevent potential NULL pointer dereferences in the future is to implement a check for cifs_sb->rsize during the mount stage. If the value is found to be 0, the mount process should exit early to avoid any subsequent NULL pointer dereferences.

[PATCH OLK-6.6] cifs: Prevent NULL pointer dereference caused by cifs_sb->rsize is 0
by Wang Zhaolong 25 Feb '25

25 Feb '25

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBO3FG -------------------------------- When cifs_sb->rsize is 0, cifs_send_async_read() fails to allocate the pages array using iov_iter_get_pages_alloc(), resulting in data->pages being NULL. This eventually triggers a NULL pointer dereference in the callback function uncached_fill_pages(). cifs_sb->rsize is set to the minimum value between SMB3_DEFAULT_IOSIZE and server->max_read. SMB3_DEFAULT_IOSIZE is 4MB. There are two reasons that cause cifs_sb->rsize to be 0: 1. During the negotiation process, if the server returns an rsp->MaxReadSize of 0, server->max_read is assigned 0. And the calculated value of cifs_sb->rsize becomes 0. 2. In the cifsd thread, if cifs_reconnect() is invoked, server->max_read is set to 0. Prior to the completion of the reconnection process, the calculated value of cifs_sb->rsize becomes 0. It is important to note that cifs_sb->rsize is only set to 0 during the mount phase. Therefore, a straightforward approach to prevent potential NULL pointer dereferences in the future is to implement a check for cifs_sb->rsize during the mount stage. If the value is found to be 0, the mount process should exit early to avoid any subsequent NULL pointer dereferences.

[PATCH OLK-6.6] smb: client: Fix netns refcount imbalance causing leaks and use-after-free
by Wang Zhaolong 25 Feb '25

25 Feb '25

maillist inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBNCLL CVE: NA Reference: https://lore.kernel.org/linux-cifs/CAH2r5muqxgPy=n4Aks_k-2goEZmmD10Dx3u3jgO… --------------------------------------------- Commit ef7134c7fc48 ("smb: client: Fix use-after-free of network namespace.") attempted to fix a netns use-after-free issue by manually adjusting reference counts via sk->sk_net_refcnt and sock_inuse_add(). However, a later commit e9f2517a3e18 ("smb: client: fix TCP timers deadlock after rmmod") pointed out that the approach of manually setting sk->sk_net_refcnt in the first commit was technically incorrect, as sk->sk_net_refcnt should only be set for user sockets. It led to issues like TCP timers not being cleared properly on close. The second commit moved to a model of just holding an extra netns reference for server->ssocket using get_net(), and dropping it when the server is torn down. But there remain some gaps in the get_net()/put_net() balancing added by these commits. The incomplete reference handling in these fixes results in two issues: 1. Netns refcount leaks[1] The problem process is as follows: ``` mount.cifs cifsd cifs_do_mount cifs_mount cifs_mount_get_session cifs_get_tcp_session get_net() /* First get net. */ ip_connect generic_ip_connect /* Try port 445 */ get_net() ->connect() /* Failed */ put_net() generic_ip_connect /* Try port 139 */ get_net() /* Missing matching put_net() for this get_net().*/ cifs_get_smb_ses cifs_negotiate_protocol smb2_negotiate SMB2_negotiate cifs_send_recv wait_for_response cifs_demultiplex_thread cifs_read_from_socket cifs_readv_from_socket cifs_reconnect cifs_abort_connection sock_release(); server->ssocket = NULL; /* Missing put_net() here. */ generic_ip_connect get_net() ->connect() /* Failed */ put_net() sock_release(); server->ssocket = NULL; free_rsp_buf ... clean_demultiplex_info /* It's only called once here. */ put_net() ``` When cifs_reconnect() is triggered, the server->ssocket is released without a corresponding put_net() for the reference acquired in generic_ip_connect() before. it ends up calling generic_ip_connect() again to retry get_net(). After that, server->ssocket is set to NULL in the error path of generic_ip_connect(), and the net count cannot be released in the final clean_demultiplex_info() function. 2. Potential use-after-free The current refcounting scheme can lead to a potential use-after-free issue in the following scenario: ``` cifs_do_mount cifs_mount cifs_mount_get_session cifs_get_tcp_session get_net() /* First get net */ ip_connect generic_ip_connect get_net() bind_socket kernel_bind /* failed */ put_net() /* after out_err_crypto_release label */ put_net() /* after out_err label */ put_net() ``` In the exception handling process where binding the socket fails, the get_net() and put_net() calls are unbalanced, which may cause the server->net reference count to drop to zero and be prematurely released. To address both issues, this patch ties the netns reference counting to the server->ssocket and server lifecycles. The extra reference is now acquired when the server or socket is created, and released when the socket is destroyed or the server is torn down.

[PATCH openEuler-25.03 v3 0/4] Add TrIO support in EROFS
by Hongbo Li 25 Feb '25

25 Feb '25

TrIO can accelerate the cold start of containers during on-demand loading. It aggregates the read I/O operations required for container runtime during the first container launch. In the following startups, TrIO pulls the necessary I/O data to the container node in a single large I/O operation and uses this I/O information to construct the runtime rootfs. By improving the efficiency of network I/O, TrIO speeds up container startup in on-demand loading scenarios. TrIO consists of both kernel-space and user-space code. The kernel-space code has been adapted at the overlayfs layer, introducing the CONFIG_EROFS_TRIO configuration to provide isolation. The user-space code requires adaptation by the user, and detailed usage methods are introduced in the tools/trio/README.md section. Patches 1~2 correspond to the kernel adaptations, while patches 3~4 are the scripts and best practices that TrIO relies on for its operation. v3: - Obtain and keep the trio_object in open. - Only close readahead in trio case.

[PATCH OLK-6.6] USB: serial: quatech2: fix null-ptr-deref in qt2_process_read_urb()

From: Qasim Ijaz <qasdev00(a)gmail.com> stable inclusion from stable-v6.6.75 commit 6377838560c03b36e1153a42ef727533def9b68f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBLDIN CVE: CVE-2025-21689 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 575a5adf48b06a2980c9eeffedf699ed5534fade upstream. This patch addresses a null-ptr-deref in qt2_process_read_urb() due to an incorrect bounds check in the following: if (newport > serial->num_ports) { dev_err(&port->dev, "%s - port change to invalid port: %i\n", __func__, newport); break; } The condition doesn't account for the valid range of the serial->port buffer, which is from 0 to serial->num_ports - 1. When newport is equal to serial->num_ports, the assignment of "port" in the following code is out-of-bounds and NULL: serial_priv->current_port = newport; port = serial->port[serial_priv->current_port]; The fix checks if newport is greater than or equal to serial->num_ports indicating it is out-of-bounds.

[PATCH openEuler-1.0-LTS_cifs_netns_leak] smb: client: Fix netns refcount imbalance causing leaks and use-after-free
by Wang Zhaolong 24 Feb '25

24 Feb '25

maillist inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBNCLL CVE: NA Reference: https://lore.kernel.org/linux-cifs/CAH2r5muqxgPy=n4Aks_k-2goEZmmD10Dx3u3jgO… --------------------------------------------- Commit ef7134c7fc48 ("smb: client: Fix use-after-free of network namespace.") attempted to fix a netns use-after-free issue by manually adjusting reference counts via sk->sk_net_refcnt and sock_inuse_add(). However, a later commit e9f2517a3e18 ("smb: client: fix TCP timers deadlock after rmmod") pointed out that the approach of manually setting sk->sk_net_refcnt in the first commit was technically incorrect, as sk->sk_net_refcnt should only be set for user sockets. It led to issues like TCP timers not being cleared properly on close. The second commit moved to a model of just holding an extra netns reference for server->ssocket using get_net(), and dropping it when the server is torn down. But there remain some gaps in the get_net()/put_net() balancing added by these commits. The incomplete reference handling in these fixes results in two issues: 1. Netns refcount leaks[1] The problem process is as follows: ``` mount.cifs cifsd cifs_do_mount cifs_mount cifs_mount_get_session cifs_get_tcp_session get_net() /* First get net. */ ip_connect generic_ip_connect /* Try port 445 */ get_net() ->connect() /* Failed */ put_net() generic_ip_connect /* Try port 139 */ get_net() /* Missing matching put_net() for this get_net().*/ cifs_get_smb_ses cifs_negotiate_protocol smb2_negotiate SMB2_negotiate cifs_send_recv wait_for_response cifs_demultiplex_thread cifs_read_from_socket cifs_readv_from_socket cifs_reconnect cifs_abort_connection sock_release(); server->ssocket = NULL; /* Missing put_net() here. */ generic_ip_connect get_net() ->connect() /* Failed */ put_net() sock_release(); server->ssocket = NULL; free_rsp_buf ... clean_demultiplex_info /* It's only called once here. */ put_net() ``` When cifs_reconnect() is triggered, the server->ssocket is released without a corresponding put_net() for the reference acquired in generic_ip_connect() before. it ends up calling generic_ip_connect() again to retry get_net(). After that, server->ssocket is set to NULL in the error path of generic_ip_connect(), and the net count cannot be released in the final clean_demultiplex_info() function. 2. Potential use-after-free The current refcounting scheme can lead to a potential use-after-free issue in the following scenario: ``` cifs_do_mount cifs_mount cifs_mount_get_session cifs_get_tcp_session get_net() /* First get net */ ip_connect generic_ip_connect get_net() bind_socket kernel_bind /* failed */ put_net() /* after out_err_crypto_release label */ put_net() /* after out_err label */ put_net() ``` In the exception handling process where binding the socket fails, the get_net() and put_net() calls are unbalanced, which may cause the server->net reference count to drop to zero and be prematurely released. To address both issues, this patch ties the netns reference counting to the server->ssocket and server lifecycles. The extra reference is now acquired when the server or socket is created, and released when the socket is destroyed or the server is torn down.

[PATCH openEuler-1.0-LTS] cifs: Prevent NULL pointer dereference caused by cifs_sb->rsize is 0
by Wang Zhaolong 24 Feb '25

24 Feb '25

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBO3FG CVE: NA -------------------------------- When cifs_sb->rsize is 0, cifs_send_async_read() fails to allocate the pages array using iov_iter_get_pages_alloc(), resulting in data->pages being NULL. This eventually triggers a NULL pointer dereference in the callback function uncached_fill_pages(). cifs_sb->rsize is set to the minimum value between SMB3_DEFAULT_IOSIZE and server->max_read. SMB3_DEFAULT_IOSIZE is 4MB. There are two reasons that cause cifs_sb->rsize to be 0: 1. During the negotiation process, if the server returns an rsp->MaxReadSize of 0, server->max_read is assigned 0. And the calculated value of cifs_sb->rsize becomes 0. 2. In the cifsd thread, if cifs_reconnect() is invoked, server->max_read is set to 0. Prior to the completion of the reconnection process, the calculated value of cifs_sb->rsize becomes 0. It is important to note that cifs_sb->rsize is only set to 0 during the mount phase.

[PATCH OLK-5.10] cifs: Prevent NULL pointer dereference caused by cifs_sb->rsize is 0
by Wang Zhaolong 24 Feb '25

24 Feb '25

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBO3FG CVE: NA -------------------------------- When cifs_sb->rsize is 0, cifs_send_async_read() fails to allocate the pages array using iov_iter_get_pages_alloc(), resulting in data->pages being NULL. This eventually triggers a NULL pointer dereference in the callback function uncached_fill_pages(). cifs_sb->rsize is set to the minimum value between SMB3_DEFAULT_IOSIZE and server->max_read. SMB3_DEFAULT_IOSIZE is 4MB. There are two reasons that cause cifs_sb->rsize to be 0: 1. During the negotiation process, if the server returns an rsp->MaxReadSize of 0, server->max_read is assigned 0. And the calculated value of cifs_sb->rsize becomes 0. 2. In the cifsd thread, if cifs_reconnect() is invoked, server->max_read is set to 0. Prior to the completion of the reconnection process, the calculated value of cifs_sb->rsize becomes 0. It is important to note that cifs_sb->rsize is only set to 0 during the mount phase. Therefore, a straightforward approach to prevent potential NULL pointer dereferences in the future is to implement a check for cifs_sb->rsize during the mount stage. If the value is found to be 0, the mount process should exit early to avoid any subsequent NULL pointer dereferences.

[PATCH openEuler-25.03 00/20] mm: arm64: Add kernel replication feature
by Denis Darvish 24 Feb '25

24 Feb '25

This patchset implements initial support of kernel text and rodata replication for AArch64. openEuler 25.03 is used as a baseline. Current implementation supports next functionality: 1. Replicated kernel text and rodata per-NUMA node 2. Vmalloc is able to work with replicated areas, so kernel modules text and rodata also replicated during modules loading stage. 3. BPF handlers are not replicated by default, but this can be easily done by using existent APIs. 4. KPROBES, KGDB and all functionality that depends on kernel text patching work without any limitation. 5. KPTI, KASLR, and KASAN fully supported. 6. Replicates parts of translation table related to replicated text and rodata. 7. 4K and 64K pages are supported. Translation tables synchronization is necessary only in several special cases: 1. Kernel boot 2. Modules deployment 3. Any allocation in user space that require new PUD/P4D In current design mutable kernel data modifications don't require synchronization between translation tables due to on 64-bit platforms all physical memory already mapped in kernel space and this mapping is persistent. In user space the translation tables synchronizations are quite rare due to the only case is new PUD/P4D allocation. At the current stage only the PGD layer is replicated for the user space. Please refer to the next pics.

From: Jann Horn <jannh(a)google.com> stable inclusion from stable-v6.6.79 commit 6abb510251e75f875797d8983a830e6731fa281c category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBO4LT CVE: CVE-2025-21704 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit e563b01208f4d1f609bcab13333b6c0e24ce6a01 upstream. If the first fragment is shorter than struct usb_cdc_notification, we can't calculate an expected_size. Log an error and discard the notification instead of reading lengths from memory outside the received data, which can lead to memory corruption when the expected_size decreases between fragments, causing `expected_size - acm->nb_index` to wrap. This issue has been present since the beginning of git history; however, it only leads to memory corruption since commit ea2583529cd1 ("cdc-acm: reassemble fragmented notifications"). A mitigating factor is that acm_ctrl_irq() can only execute after userspace has opened /dev/ttyACM*; but if ModemManager is running, ModemManager will do that automatically depending on the USB device's vendor/product IDs and its other interfaces.

[PATCH OLK-5.10] iio: pressure: zpa2326: fix information leak in triggered buffer

From: Javier Carrasco <javier.carrasco.cruz(a)gmail.com> stable inclusion from stable-v6.6.72 commit fefb88a4da961a0b9c2473cbdcfce1a942fcfa9a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBIQW6 CVE: CVE-2024-57912 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 6007d10c5262f6f71479627c1216899ea7f09073 upstream. The 'sample' local struct is used to push data to user space from a triggered buffer, but it has a hole between the temperature and the timestamp (u32 pressure, u16 temperature, GAP, u64 timestamp). This hole is never initialized. Initialize the struct to zero before using it to avoid pushing uninitialized information to userspace.

[PATCH openEuler-25.03 v2 0/4] Add TrIO support in EROFS
by Hongbo Li 21 Feb '25

21 Feb '25

TrIO can accelerate the cold start of containers during on-demand loading. It aggregates the read I/O operations required for container runtime during the first container launch. In the following startups, TrIO pulls the necessary I/O data to the container node in a single large I/O operation and uses this I/O information to construct the runtime rootfs. By improving the efficiency of network I/O, TrIO speeds up container startup in on-demand loading scenarios. TrIO consists of both kernel-space and user-space code. The kernel-space code has been adapted at the overlayfs layer, introducing the CONFIG_EROFS_TRIO configuration to provide isolation. The user-space code requires adaptation by the user, and detailed usage methods are introduced in the tools/trio/README.md section. Patches 1~2 correspond to the kernel adaptations, while patches 3~4 are the scripts and best practices that TrIO relies on for its operation.

[PATCH OLK-6.6] kobject: Fix global-out-of-bounds in kobject_action_type()
by Xia Fukun 21 Feb '25

21 Feb '25

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9REGZ CVE: NA -------------------------------- The following c language code can trigger KASAN's global variable out-of-bounds access error in kobject_action_type(): int main() { int fd; char *filename = "/sys/block/ram12/uevent"; char str[86] = "offline"; int len = 86; fd = open(filename, O_WRONLY); if (fd == -1) { printf("open"); exit(1); } if (write(fd, str, len) == -1) { printf("write"); exit(1); } close(fd); return 0; } Function kobject_action_type() receives the input parameters buf and count, where count is the length of the string buf. In the use case we provided, count is 86, the count_first is 85. Buf points to a string with a length of 86, and its first seven characters are "offline". In line 87 of the code, kobject_actions[action] is the string "offline" with the length of 7,an out-of-boundary access will appear: kobject_actions[action][85]. Modify the judgment logic in line 87. If the length of the string kobject_actions[action] is greater than count_first(e.g. buf is "off", count is 3), continue the loop. Otherwise, the match is considered successful. This change means that our test case will be successfully parsed as an offline event and no out-of-bounds access error will occur.

[PATCH OLK-6.6] virtio-blk: don't keep queue frozen during system suspend
by Zheng Qixing 21 Feb '25

21 Feb '25

From: Ming Lei <ming.lei(a)redhat.com> stable inclusion from stable-v6.6.69 commit 12c0ddd6c551c1e438b087f874b4f1223a75f7ea category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBJ6SJ CVE: CVE-2024-57946 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------- [ Upstream commit 7678abee0867e6b7fb89aa40f6e9f575f755fb37 ] Commit 4ce6e2db00de ("virtio-blk: Ensure no requests in virtqueues before deleting vqs.") replaces queue quiesce with queue freeze in virtio-blk's PM callbacks. And the motivation is to drain inflight IOs before suspending. block layer's queue freeze looks very handy, but it is also easy to cause deadlock, such as, any attempt to call into bio_queue_enter() may run into deadlock if the queue is frozen in current context. There are all kinds of ->suspend() called in suspend context, so keeping queue frozen in the whole suspend context isn't one good idea. And Marek reported lockdep warning[1] caused by virtio-blk's freeze queue in virtblk_freeze().

However, the case that waker_bfqq is not in the merge chain is missed, and if the procress reference of waker_bfqq is 0, waker_bfqq can be freed as well.

[PATCH OLK-6.6] riscv: mm: Fix the out of bound issue of vmemmap address
by Heyuan Wang 21 Feb '25

21 Feb '25

From: Xu Lu <luxu.kernel(a)bytedance.com> mainline inclusion from mainline-v6.13-rc7 commit f754f27e98f88428aaf6be6e00f5cbce97f62d4b category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBJ6RK CVE: CVE-2024-57945 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- In sparse vmemmap model, the virtual address of vmemmap is calculated as: ((struct page *)VMEMMAP_START - (phys_ram_base >> PAGE_SHIFT)). And the struct page's va can be calculated with an offset: (vmemmap + (pfn)). However, when initializing struct pages, kernel actually starts from the first page from the same section that phys_ram_base belongs to. If the first page's physical address is not (phys_ram_base >> PAGE_SHIFT), then we get an va below VMEMMAP_START when calculating va for it's struct page. For example, if phys_ram_base starts from 0x82000000 with pfn 0x82000, the first page in the same section is actually pfn 0x80000. During init_unavailable_range(), we will initialize struct page for pfn 0x80000 with virtual address ((struct page *)VMEMMAP_START - 0x2000), which is below VMEMMAP_START as well as PCI_IO_END. This commit fixes this bug by introducing a new variable 'vmemmap_start_pfn' which is aligned with memory section size and using it to calculate vmemmap address instead of phys_ram_base.

[PATCH OLK-6.6] fs: relax assertions on failure to encode file handles
by Long Li 21 Feb '25

21 Feb '25

From: Amir Goldstein <amir73il(a)gmail.com> mainline inclusion from mainline-v6.10-rc2 commit 974e3fe0ac61de85015bbe5a4990cf4127b304b2 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBIQX7 CVE: CVE-2024-57924 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Encoding file handles is usually performed by a filesystem >encode_fh() method that may fail for various reasons. The legacy users of exportfs_encode_fh(), namely, nfsd and name_to_handle_at(2) syscall are ready to cope with the possibility of failure to encode a file handle. There are a few other users of exportfs_encode_{fh,fid}() that currently have a WARN_ON() assertion when ->encode_fh() fails. Relax those assertions because they are wrong. The second linked bug report states commit 16aac5ad1fa9 ("ovl: support encoding non-decodable file handles") in v6.6 as the regressing commit, but this is not accurate. The aforementioned commit only increases the chances of the assertion and allows triggering the assertion with the reproducer using overlayfs, inotify and drop_caches. Triggering this assertion was always possible with other filesystems and other reasons of ->encode_fh() failures and more particularly, it was also possible with the exact same reproducer using overlayfs that is mounted with options index=on,nfs_export=on also on kernels < v6.6. Therefore, I am not listing the aforementioned commit as a Fixes commit. Backport hint: this patch will have a trivial conflict applying to v6.6.y, and other trivial conflicts applying to stable kernels < v6.6.

[PATCH OLK-6.6 v2] tracing: Have process_string() also allow arrays
by Pu Lehui 21 Feb '25

21 Feb '25

From: Steven Rostedt <rostedt(a)goodmis.org> stable inclusion from stable-v6.6.70 commit a64e5295ebc4afdefe69cdf16cc286a60ff8ba4b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBJ6PG CVE: CVE-2024-57930 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit afc6717628f959941d7b33728570568b4af1c4b8 upstream. In order to catch a common bug where a TRACE_EVENT() TP_fast_assign() assigns an address of an allocated string to the ring buffer and then references it in TP_printk(), which can be executed hours later when the string is free, the function test_event_printk() runs on all events as they are registered to make sure there's no unwanted dereferencing. It calls process_string() to handle cases in TP_printk() format that has "%s". It returns whether or not the string is safe. But it can have some false positives. For instance, xe_bo_move() has: TP_printk("move_lacks_source:%s, migrate object %p [size %zu] from %s to %s device_id:%s", __entry->move_lacks_source ? "yes" : "no", __entry->bo, __entry->size, xe_mem_type_to_name[__entry->old_placement], xe_mem_type_to_name[__entry->new_placement], __get_str(device_id)) Where the "%s" references into xe_mem_type_to_name[]. This is an array of pointers that should be safe for the event to access. Instead of flagging this as a bad reference, if a reference points to an array, where the record field is the index, consider it safe.

[PATCH OLK-6.6] tracing: Have process_string() also allow arrays
by Pu Lehui 20 Feb '25

20 Feb '25

From: Steven Rostedt <rostedt(a)goodmis.org> stable inclusion from stable-v6.6.70 commit a64e5295ebc4afdefe69cdf16cc286a60ff8ba4b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBJ6PG CVE: CVE-2024-57930 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit afc6717628f959941d7b33728570568b4af1c4b8 upstream. In order to catch a common bug where a TRACE_EVENT() TP_fast_assign() assigns an address of an allocated string to the ring buffer and then references it in TP_printk(), which can be executed hours later when the string is free, the function test_event_printk() runs on all events as they are registered to make sure there's no unwanted dereferencing. It calls process_string() to handle cases in TP_printk() format that has "%s". It returns whether or not the string is safe. But it can have some false positives. For instance, xe_bo_move() has: TP_printk("move_lacks_source:%s, migrate object %p [size %zu] from %s to %s device_id:%s", __entry->move_lacks_source ? "yes" : "no", __entry->bo, __entry->size, xe_mem_type_to_name[__entry->old_placement], xe_mem_type_to_name[__entry->new_placement], __get_str(device_id)) Where the "%s" references into xe_mem_type_to_name[].

[PATCH OLK-6.6] mm/thp: fix deferred split unqueue naming and locking
by Liu Shixin 20 Feb '25

20 Feb '25

From: Hugh Dickins <hughd(a)google.com> stable inclusion from stable-v6.6.62 commit fc4951c3e3358dd82ea508e893695b916c813f17 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB5KQW CVE: CVE-2024-53079 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit f8f931bba0f92052cf842b7e30917b1afcc77d5a upstream. Recent changes are putting more pressure on THP deferred split queues: under load revealing long-standing races, causing list_del corruptions, "Bad page state"s and worse (I keep BUGs in both of those, so usually don't get to see how badly they end up without). The relevant recent changes being 6.8's mTHP, 6.10's mTHP swapout, and 6.12's mTHP swapin, improved swap allocation, and underused THP splitting. Before fixing locking: rename misleading folio_undo_large_rmappable(), which does not undo large_rmappable, to folio_unqueue_deferred_split(), which is what it does. But that and its out-of-line __callee are mm internals of very limited usability: add comment and WARN_ON_ONCEs to check usage; and return a bool to say if a deferred split was unqueued, which can then be used in WARN_ON_ONCEs around safety checks (sparing callers the arcane conditionals in __folio_unqueue_deferred_split()). Just omit the folio_unqueue_deferred_split() from free_unref_folios(), all of whose callers now call it beforehand (and if any forget then bad_page() will tell) - except for its caller put_pages_list(), which itself no longer has any callers (and will be deleted separately). Swapout: mem_cgroup_swapout() has been resetting folio->memcg_data 0 without checking and unqueueing a THP folio from deferred split list; which is unfortunate, since the split_queue_lock depends on the memcg (when memcg is enabled); so swapout has been unqueueing such THPs later, when freeing the folio, using the pgdat's lock instead: potentially corrupting the memcg's list. __remove_mapping() has frozen refcount to 0 here, so no problem with calling folio_unqueue_deferred_split() before resetting memcg_data. That goes back to 5.4 commit 87eaceb3faa5 ("mm: thp: make deferred split shrinker memcg aware"): which included a check on swapcache before adding to deferred queue, but no check on deferred queue before adding THP to swapcache. That worked fine with the usual sequence of events in reclaim (though there were a couple of rare ways in which a THP on deferred queue could have been swapped out), but 6.12 commit dafff3f4c850 ("mm: split underused THPs") avoids splitting underused THPs in reclaim, which makes swapcache THPs on deferred queue commonplace. Keep the check on swapcache before adding to deferred queue? Yes: it is no longer essential, but preserves the existing behaviour, and is likely to be a worthwhile optimization (vmstat showed much more traffic on the queue under swapping load if the check was removed); update its comment. Memcg-v1 move (deprecated): mem_cgroup_move_account() has been changing folio->memcg_data without checking and unqueueing a THP folio from the deferred list, sometimes corrupting "from" memcg's list, like swapout. Refcount is non-zero here, so folio_unqueue_deferred_split() can only be used in a WARN_ON_ONCE to validate the fix, which must be done earlier: mem_cgroup_move_charge_pte_range() first try to split the THP (splitting of course unqueues), or skip it if that fails. Not ideal, but moving charge has been requested, and khugepaged should repair the THP later: nobody wants new custom unqueueing code just for this deprecated case. The 87eaceb3faa5 commit did have the code to move from one deferred list to another (but was not conscious of its unsafety while refcount non-0); but that was removed by 5.6 commit fac0516b5534 ("mm: thp: don't need care deferred split queue in memcg charge move path"), which argued that the existence of a PMD mapping guarantees that the THP cannot be on a deferred list. As above, false in rare cases, and now commonly false. Backport to 6.11 should be straightforward. Earlier backports must take care that other _deferred_list fixes and dependencies are included. There is not a strong case for backports, but they can fix cornercases.

[PATCH OLK-5.10] Revert "media: uvcvideo: Require entities to have a non-zero unique ID"
by Tong Tiangen 19 Feb '25

19 Feb '25

From: Thadeu Lima de Souza Cascardo <cascardo(a)igalia.com> stable inclusion from stable-v6.6.78 commit a80f82d31ca67f064693d776d86dc60524ca2cee category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBN5F1 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 8004d635f27bbccaa5c083c50d4d5302a6ffa00e upstream. This reverts commit 3dd075fe8ebbc6fcbf998f81a75b8c4b159a6195. Tomasz has reported that his device, Generalplus Technology Inc. 808 Camera, with ID 1b3f:2002, stopped being detected: $ ls -l /dev/video* zsh: no matches found: /dev/video* [ 7.230599] usb 3-2: Found multiple Units with ID 5 This particular device is non-compliant, having both the Output Terminal and Processing Unit with ID 5. uvc_scan_fallback, though, is able to build a chain. However, when media elements are added and uvc_mc_create_links call uvc_entity_by_id, it will get the incorrect entity, media_create_pad_link will WARN, and it will fail to register the entities. In order to reinstate support for such devices in a timely fashion, reverting the fix for these warnings is appropriate. A proper fix that considers the existence of such non-compliant devices will be submitted in a later development cycle.

[PATCH OLK-6.6] hwmon: (drivetemp) Fix driver producing garbage data when SCSI errors occur
by Chen Ridong 19 Feb '25

19 Feb '25

From: Daniil Stas <daniil.stas(a)posteo.net> stable inclusion from stable-v6.6.72 commit 53e25b10a28edaf8c2a1d3916fd8929501a50dfc category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBJ6R2 CVE: CVE-2025-21656 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 82163d63ae7a4c36142cd252388737205bb7e4b9 ] scsi_execute_cmd() function can return both negative (linux codes) and positive (scsi_cmnd result field) error codes. Currently the driver just passes error codes of scsi_execute_cmd() to hwmon core, which is incorrect because hwmon only checks for negative error codes. This leads to hwmon reporting uninitialized data to userspace in case of SCSI errors (for example if the disk drive was disconnected).

From: Ranjan Kumar <ranjan.kumar(a)broadcom.com> mainline inclusion from mainline-v6.13-rc2 commit 711201a8b8334a397440ac0b859df0054e174bc9 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBIDGN CVE: CVE-2024-57804 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ---------------------------------------------------------------------- The driver, through the SAS transport, exposes a sysfs interface to enable/disable PHYs in a controller/expander setup. When multiple PHYs are disabled and enabled in rapid succession, the persistent and current config pages related to SAS IO unit/SAS Expander pages could get corrupted. Use separate memory for each config request.

[PATCH OLK-6.6] iio: adc: rockchip_saradc: fix information leak in triggered buffer

The root cause of the issue is that the function drm_sched_fini is called before drm_sched_entity_kill. In drm_sched_fini, the drm_sched_rq structure is freed, but this structure is later accessed by each entity within the run queue, leading to invalid memory access. To resolve this, the order of cleanup calls is updated: Before: amdgpu_fence_driver_sw_fini amdgpu_device_ip_fini After: amdgpu_device_ip_fini amdgpu_fence_driver_sw_fini This updated order ensures that all entities in the IPs are cleaned up first, followed by proper cleanup of the schedulers. Additional Investigation: During debugging, another issue was identified in the amdgpu_vce_sw_fini function. The vce.vcpu_bo buffer must be freed only as the final step in the cleanup process to prevent any premature access during earlier cleanup stages. v2: Using Christian suggestion call drm_sched_entity_destroy before drm_sched_fini.

From: Christophe JAILLET <christophe.jaillet(a)wanadoo.fr> stable inclusion from stable-v5.10.231 commit cc386170b3312fd7b5bc4a69a9f52d7f50814526 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEGFF CVE: CVE-2024-56754 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit ad980b04f51f7fb503530bd1cb328ba5e75a250e ] The type of the last parameter given to devm_add_action_or_reset() is "struct caam_drv_private *", but in caam_qi_shutdown(), it is casted to "struct device *". Pass the correct parameter to devm_add_action_or_reset() so that the resources are released as expected.

[PATCH OLK-5.10] iommu/arm-smmu: Defer probe of clients after smmu device bound
by Zhang Zekun 18 Feb '25

18 Feb '25

From: Pratyush Brahma <quic_pbrahma(a)quicinc.com> stable inclusion from stable-v5.10.231 commit c2527d07c7e9cda2c6165d5edccf74752baac1b0 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAME CVE: CVE-2024-56568 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 229e6ee43d2a160a1592b83aad620d6027084aad upstream. Null pointer dereference occurs due to a race between smmu driver probe and client driver probe, when of_dma_configure() for client is called after the iommu_device_register() for smmu driver probe has executed but before the driver_bound() for smmu driver has been called. Following is how the race occurs: T1:Smmu device probe T2: Client device probe really_probe() arm_smmu_device_probe() iommu_device_register() really_probe() platform_dma_configure() of_dma_configure() of_dma_configure_id() of_iommu_configure() iommu_probe_device() iommu_init_device() arm_smmu_probe_device() arm_smmu_get_by_fwnode() driver_find_device_by_fwnode() driver_find_device() next_device() klist_next() /* null ptr assigned to smmu */ /* null ptr dereference while smmu->streamid_mask */ driver_bound() klist_add_tail() When this null smmu pointer is dereferenced later in arm_smmu_probe_device, the device crashes. Fix this by deferring the probe of the client device until the smmu device has bound to the arm smmu driver.
