[PATCH openEuler-1.0-LTS] arm64: asm-bug: Add .align 2 to the end of __BUG_ENTRY
by Li Zetao 03 Jun '24

From: Jiangfeng Xiao <xiaojiangfeng(a)huawei.com> mainline inclusion from mainline-v6.10-rc1 commit ffbf4fb9b5c12ff878a10ea17997147ea4ebea6f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9R0VC CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- When CONFIG_DEBUG_BUGVERBOSE=n, we fail to add necessary padding bytes to bug_table entries, and as a result the last entry in a bug table will be ignored, potentially leading to an unexpected panic(). All prior entries in the table will be handled correctly. The arm64 ABI requires that struct fields of up to 8 bytes are naturally-aligned, with padding added within a struct such that struct are suitably aligned within arrays. When CONFIG_DEBUG_BUGVERPOSE=y, the layout of a bug_entry is: struct bug_entry { signed int bug_addr_disp; // 4 bytes signed int file_disp; // 4 bytes unsigned short line; // 2 bytes unsigned short flags; // 2 bytes } ... with 12 bytes total, requiring 4-byte alignment. When CONFIG_DEBUG_BUGVERBOSE=n, the layout of a bug_entry is: struct bug_entry { signed int bug_addr_disp; // 4 bytes unsigned short flags; // 2 bytes < implicit padding > // 2 bytes } ... with 8 bytes total, with 6 bytes of data and 2 bytes of trailing padding, requiring 4-byte alginment. When we create a bug_entry in assembly, we align the start of the entry to 4 bytes, which implicitly handles padding for any prior entries. However, we do not align the end of the entry, and so when CONFIG_DEBUG_BUGVERBOSE=n, the final entry lacks the trailing padding bytes. For the main kernel image this is not a problem as find_bug() doesn't depend on the trailing padding bytes when searching for entries: for (bug = __start___bug_table; bug < __stop___bug_table; ++bug) if (bugaddr == bug_addr(bug)) return bug; However for modules, module_bug_finalize() depends on the trailing bytes when calculating the number of entries: mod->num_bugs = sechdrs[i].sh_size / sizeof(struct bug_entry); ... and as the last bug_entry lacks the necessary padding bytes, this entry will not be counted, e.g. in the case of a single entry: sechdrs[i].sh_size == 6 sizeof(struct bug_entry) == 8; sechdrs[i].sh_size / sizeof(struct bug_entry) == 0; Consequently module_find_bug() will miss the last bug_entry when it does: for (i = 0; i < mod->num_bugs; ++i, ++bug) if (bugaddr == bug_addr(bug)) goto out; ... which can lead to a kenrel panic due to an unhandled bug. This can be demonstrated with the following module: static int __init buginit(void) { WARN(1, "hello\n"); return 0; } static void __exit bugexit(void) { } module_init(buginit); module_exit(bugexit); MODULE_LICENSE("GPL"); ... which will trigger a kernel panic when loaded: ------------[ cut here ]------------ hello Unexpected kernel BRK exception at EL1 Internal error: BRK handler: 00000000f2000800 [#1] PREEMPT SMP Modules linked in: hello(O+) CPU: 0 PID: 50 Comm: insmod Tainted: G O 6.9.1 #8 Hardware name: linux,dummy-virt (DT) pstate: 60400005 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : buginit+0x18/0x1000 [hello] lr : buginit+0x18/0x1000 [hello] sp : ffff800080533ae0 x29: ffff800080533ae0 x28: 0000000000000000 x27: 0000000000000000 x26: ffffaba8c4e70510 x25: ffff800080533c30 x24: ffffaba8c4a28a58 x23: 0000000000000000 x22: 0000000000000000 x21: ffff3947c0eab3c0 x20: ffffaba8c4e3f000 x19: ffffaba846464000 x18: 0000000000000006 x17: 0000000000000000 x16: ffffaba8c2492834 x15: 0720072007200720 x14: 0720072007200720 x13: ffffaba8c49b27c8 x12: 0000000000000312 x11: 0000000000000106 x10: ffffaba8c4a0a7c8 x9 : ffffaba8c49b27c8 x8 : 00000000ffffefff x7 : ffffaba8c4a0a7c8 x6 : 80000000fffff000 x5 : 0000000000000107 x4 : 0000000000000000 x3 : 0000000000000000 x2 : 0000000000000000 x1 : 0000000000000000 x0 : ffff3947c0eab3c0 Call trace: buginit+0x18/0x1000 [hello] do_one_initcall+0x80/0x1c8 do_init_module+0x60/0x218 load_module+0x1ba4/0x1d70 __do_sys_init_module+0x198/0x1d0 __arm64_sys_init_module+0x1c/0x28 invoke_syscall+0x48/0x114 el0_svc_common.constprop.0+0x40/0xe0 do_el0_svc+0x1c/0x28 el0_svc+0x34/0xd8 el0t_64_sync_handler+0x120/0x12c el0t_64_sync+0x190/0x194 Code: d0ffffe0 910003fd 91000000 9400000b (d4210000) ---[ end trace 0000000000000000 ]--- Kernel panic - not syncing: BRK handler: Fatal exception Fix this by always aligning the end of a bug_entry to 4 bytes, which is correct regardless of CONFIG_DEBUG_BUGVERBOSE.

[PATCH OLK-5.10 1/2] iommu/iova: free iovas on each cpu in flush queue
by Zhang Zekun 03 Jun '24

03 Jun '24

During the subsequent initialization, set_power_state gets called to transition to the final power state. set_power_state refers to values from the current state and without current state populated, it could result in NULL pointer dereference. For ex: on platforms where PCI speed change is supported through ACPI ATCS method, the link speed of current state needs to be queried before deciding on changing to final power state's link speed. The logic to query ATCS-support was broken on certain platforms. The issue became visible when broken ATCS-support logic got fixed with commit f9b7f3703ff9 ("drm/amdgpu/acpi: make ATPX/ATCS structures global (v2)").

[PATCH OLK-5.10 v2 00/11] Memory access profiler(SPE) driven NUMA balancing
by Ze Zuo 02 Jun '24

02 Jun '24

Hi, In Arm processors, there is a hardware PMU (Performance Monitoring Unit) facility called Statistical Profiling Extension (SPE) that can gather memory access metrics. In this patchset, SPE is exploited as an access information sampling approach to drive NUMA balancing. This sampling approach is introducedto replace the method based on address space scanning and hint faults with the access information provided by the hardware. With this, it is no longer necessary for NUMA balancing to scan over the address space periodically and rely on task-to-page association built by NUMA hint faults. Instead, the access samples obtained from hardware PMU are fed to NUMA balancing as equivalents to page fault. Except for the replaced sampling approach, the rest of the NUMA balancing policy is retained to do pages and tasks migrations according to the samples. Profiling based on SPE is an valid alternative sampling approach in NUMA balancing for the optimal page and task placement. This can be also extended to other architectures as long as there is a hardware PMU that supports memory access profiling. An abstract layer mem_sampling is introduced to reserve support for other kernel features and different types of hardware PMU. To help evaluate performance of this approach in system, syctl interfaces are added to enable/disable hardware mem sampling. NUMA balancing sampling approach can be also switched back to hint-faults- based approach dynamically. TODOs Currently, SPE for NUMA balance does not support PMD-level page migration, but it will be supported in later version. Changes since v1: -- clean code, no functional change.

[PATCH openEuler-1.0-LTS] comedi: dt9812: fix DMA buffers on stack
by Wang Hai 01 Jun '24

01 Jun '24

From: Johan Hovold <johan(a)kernel.org> stable inclusion from stable-v4.19.217 commit 39ea61037ae78f14fa121228dd962ea3280eacf3 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RD6O CVE: CVE-2021-47477 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 536de747bc48262225889a533db6650731ab25d3 upstream. USB transfer buffers are typically mapped for DMA and must not be allocated on the stack or transfers will fail. Allocate proper transfer buffers in the various command helpers and return an error on short transfers instead of acting on random stack data. Note that this also fixes a stack info leak on systems where DMA is not used as 32 bytes are always sent to the device regardless of how short the command is.

This might cause memory corruption should wmi_char_open() be unable to find its driver, something which can happen when the associated WMI device is deleted in wmi_free_devices().

[PATCH openEuler-1.0-LTS] drm/amd/pm: Update intermediate power state for SI

31 May '24

From: Lijo Lazar <lijo.lazar(a)amd.com> mainline inclusion from mainline-v5.15-rc3 commit ab39d3cef526ba09c4c6923b4cd7e6ec1c5d4faa category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9TKIT CVE: CVE-2021-47362 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- Update the current state as boot state during dpm initialization. During the subsequent initialization, set_power_state gets called to transition to the final power state. set_power_state refers to values from the current state and without current state populated, it could result in NULL pointer dereference. For ex: on platforms where PCI speed change is supported through ACPI ATCS method, the link speed of current state needs to be queried before deciding on changing to final power state's link speed. The logic to query ATCS-support was broken on certain platforms. The issue became visible when broken ATCS-support logic got fixed with commit f9b7f3703ff9 ("drm/amdgpu/acpi: make ATPX/ATCS structures global (v2)").

This could happen when orig_bio has BIO_CHAIN (split by md_submit_bio => bio_split_to_limits, for example). As a result, upper layer may miss error reported from md (or the device) and consider the failed IO was successful. Fix this by only update orig_bio->bi_status when current bio reports error and orig_bio is BLK_STS_OK. This is the same behavior as __bio_chain_endio().

From: Armin Wolf <W_Armin(a)gmx.de> stable inclusion from stable-v4.19.299 commit cf098e937dd125c0317a0d6f261ac2a950a233d6 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RFHT CVE: CVE-2023-52864 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit eba9ac7abab91c8f6d351460239108bef5e7a0b6 ] Since commit fa1f68db6ca7 ("drivers: misc: pass miscdevice pointer via file private data"), the miscdevice stores a pointer to itself inside filp->private_data, which means that private_data will not be NULL when wmi_char_open() is called. This might cause memory corruption should wmi_char_open() be unable to find its driver, something which can happen when the associated WMI device is deleted in wmi_free_devices().

From: Jack Wang <jinpu.wang(a)ionos.com> mainline inclusion from mainline-v6.6-rc1 commit 3d7d72a34e05b23e21bafc8bfb861e73c86b31f3 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9TZZB Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- On large enclaves we hit the softlockup warning with following call trace: xa_erase() sgx_vepc_release() __fput() task_work_run() do_exit() The latency issue is similar to the one fixed in: 8795359e35bc ("x86/sgx: Silence softlockup detection when releasing large enclaves") The test system has 64GB of enclave memory, and all is assigned to a single VM. Release of 'vepc' takes a longer time and causes long latencies, which triggers the softlockup warning. Add cond_resched() to give other tasks a chance to run and reduce latencies, which also avoids the softlockup detector.

[PATCH openEuler-1.0-LTS] comedi: ni_usb6501: fix NULL-deref in command paths

From: Johan Hovold <johan(a)kernel.org> stable inclusion from stable-v5.10.79 commit ef143dc0c3defe56730ecd3a9de7b3e1d7e557c1 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RD2V CVE: CVE-2021-47476 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 907767da8f3a925b060c740e0b5c92ea7dbec440 upstream. The driver uses endpoint-sized USB transfer buffers but had no sanity checks on the sizes. This can lead to zero-size-pointer dereferences or overflowed transfer buffers in ni6501_port_command() and ni6501_counter_command() if a (malicious) device has smaller max-packet sizes than expected (or when doing descriptor fuzz testing). Add the missing sanity checks to probe().

[PATCH OLK-5.10] dma-direct: Leak pages on dma_set_decrypted() failure

From: Rick Edgecombe <rick.p.edgecombe(a)intel.com> mainline inclusion from mainline-v6.9-rc1 commit b9fa16949d18e06bdf728a560f5c8af56d2bdcaf category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9QGIS CVE: CVE-2024-35939 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- On TDX it is possible for the untrusted host to cause set_memory_encrypted() or set_memory_decrypted() to fail such that an error is returned and the resulting memory is shared. Callers need to take care to handle these errors to avoid returning decrypted (shared) memory to the page allocator, which could lead to functional or security issues. DMA could free decrypted/shared pages if dma_set_decrypted() fails. This should be a rare case. Just leak the pages in this case instead of freeing them.

[PATCH openEuler-22.03-LTS-SP1] locking/ww_mutex/test: Fix potential workqueue corruption
by Xie XiuQi 31 May '24

31 May '24

From: John Stultz <jstultz(a)google.com> stable inclusion from stable-v5.10.202 commit 9ed2d68b3925145f5f51c46559484881d6082f75 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9RFIG CVE: CVE-2023-52836 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit bccdd808902f8c677317cec47c306e42b93b849e ] In some cases running with the test-ww_mutex code, I was seeing odd behavior where sometimes it seemed flush_workqueue was returning before all the work threads were finished. Often this would cause strange crashes as the mutexes would be freed while they were being used. Looking at the code, there is a lifetime problem as the controlling thread that spawns the work allocates the "struct stress" structures that are passed to the workqueue threads. Then when the workqueue threads are finished, they free the stress struct that was passed to them. Unfortunately the workqueue work_struct node is in the stress struct. Which means the work_struct is freed before the work thread returns and while flush_workqueue is waiting. It seems like a better idea to have the controlling thread both allocate and free the stress structures, so that we can be sure we don't corrupt the workqueue by freeing the structure prematurely. So this patch reworks the test to do so, and with this change I no longer see the early flush_workqueue returns.

[PATCH openEuler-1.0-LTS] net/mlx4_en: Fix an use-after-free bug in mlx4_en_try_alloc_resources()
by Pu Lehui 31 May '24

31 May '24

From: Zhou Qingyang <zhou1615(a)umn.edu> stable inclusion from stable-v4.19.220 commit 676dc7d9b15bf8733233a2db1ec3f9091ab34275 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9S1ZN CVE: CVE-2021-47541 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit addad7643142f500080417dd7272f49b7a185570 upstream. In mlx4_en_try_alloc_resources(), mlx4_en_copy_priv() is called and tmp->tx_cq will be freed on the error path of mlx4_en_copy_priv(). After that mlx4_en_alloc_resources() is called and there is a dereference of &tmp->tx_cq[t][i] in mlx4_en_alloc_resources(), which could lead to a use after free problem on failure of mlx4_en_copy_priv(). Fix this bug by adding a check of mlx4_en_copy_priv() This bug was found by a static analyzer. The analysis employs differential checking to identify inconsistent security operations (e.g., checks or kfrees) between two code paths and confirms that the inconsistent operations are not recovered in the current function or the callers, so they constitute bugs. Note that, as a bug found by static analysis, it can be a false positive or hard to trigger. Multiple researchers have cross-reviewed the bug. Builds with CONFIG_MLX4_EN=m show no new warnings, and our static analyzer no longer warns about this code.

[PATCH openEuler-22.03-LTS-SP1] perf: hisi: Fix use-after-free when register pmu fails
by Luo Gengkun 31 May '24

31 May '24

From: Junhao He <hejunhao3(a)huawei.com> mainline inclusion from mainline-v6.7-rc1 commit b805cafc604bfdb671fae7347a57f51154afa735 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RKWV CVE: CVE-2023-52859 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- When we fail to register the uncore pmu, the pmu context may not been allocated. The error handing will call cpuhp_state_remove_instance() to call uncore pmu offline callback, which migrate the pmu context. Since that's liable to lead to some kind of use-after-free. Use cpuhp_state_remove_instance_nocalls() instead of cpuhp_state_remove_instance() so that the notifiers don't execute after the PMU device has been failed to register.

[PATCH openEuler-1.0-LTS v2] loop: use lo->lo_disk for kobject_uevent
by Li Nan 30 May '24

30 May '24

hulk inclusion category: bugfix bugzilla: 189922, https://gitee.com/openeuler/kernel/issues/I9PXKA -------------------------------- The current implimentation of partitions for loop has several issues. 'loop_device' is at the gendisk level, but it uses 'lo_device' to store block_device. A gendisk can have multiple block_devices, and 'lo_device' can be set to anyone of them through loop_configure(). This usage can lead to a null-ptr-deref issue. If 'lo_device' is set to a block_device of partition, this partition is closed and 'bd_openers' is dec to 0, the 'bd_disk' of that block_device will be set to NULL in __blkdev_put(). In this case, Accessing 'lo_device->bd_disk' will trigger the issue. The problem can be reproduced as follows: 1. create loop device loop0 and create a partition loop0p1. 2. submit the ioctl LOOP_CLR_FD by loop0. 3. submit the ioctl LOOP_SET_FD by loop0p1. 4. submit ioctl such as LOOP_SET_STATUS by loop0. Fix it by using 'lo->lo_disk' instead of 'lo->lo_device->bd_disk' for kobject_uevent().

[PATCH openEuler-1.0-LTS] nilfs2: fix underflow in second superblock position calculations
by Zizhi Wo 30 May '24

30 May '24

From: Ryusuke Konishi <konishi.ryusuke(a)gmail.com> stable inclusion from stable-v4.19.273 commit b96591e2c35c8b47db0ec816b5fc6cb8868000ff category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9R4KZ CVE: CVE-2023-52705 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- commit 99b9402a36f0799f25feee4465bfa4b8dfa74b4d upstream. Macro NILFS_SB2_OFFSET_BYTES, which computes the position of the second superblock, underflows when the argument device size is less than 4096 bytes. Therefore, when using this macro, it is necessary to check in advance that the device size is not less than a lower limit, or at least that underflow does not occur. The current nilfs2 implementation lacks this check, causing out-of-bound block access when mounting devices smaller than 4096 bytes: I/O error, dev loop0, sector 36028797018963960 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 2 NILFS (loop0): unable to read secondary superblock (blocksize = 1024) In addition, when trying to resize the filesystem to a size below 4096 bytes, this underflow occurs in nilfs_resize_fs(), passing a huge number of segments to nilfs_sufile_resize(), corrupting parameters such as the number of segments in superblocks. This causes excessive loop iterations in nilfs_sufile_resize() during a subsequent resize ioctl, causing semaphore ns_segctor_sem to block for a long time and hang the writer thread: INFO: task segctord:5067 blocked for more than 143 seconds.

[PATCH openEuler-1.0-LTS] net/mlx5e: Fix memory leak in mlx5_core_destroy_cq() error path
by Zheng Zucheng 30 May '24

30 May '24

From: Valentine Fatiev <valentinef(a)nvidia.com> stable inclusion from stable-5.10.75 commit 4f7bddf8c5c01cac74373443b13a68e1c6723a94 bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RBPH CVE: CVE-2021-47438 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 94b960b9deffc02fc0747afc01f72cc62ab099e3 upstream. Prior to this patch in case mlx5_core_destroy_cq() failed it returns without completing all destroy operations and that leads to memory leak. Instead, complete the destroy flow before return error. Also move mlx5_debug_cq_remove() to the beginning of mlx5_core_destroy_cq() to be symmetrical with mlx5_core_create_cq(). kmemleak complains on: unreferenced object 0xc000000038625100 (size 64): comm "ethtool", pid 28301, jiffies 4298062946 (age 785.380s) hex dump (first 32 bytes): 60 01 48 94 00 00 00 c0 b8 05 34 c3 00 00 00 c0 `.H.......4..... 02 00 00 00 00 00 00 00 00 db 7d c1 00 00 00 c0 ..........}..... backtrace: [<000000009e8643cb>] add_res_tree+0xd0/0x270 [mlx5_core] [<00000000e7cb8e6c>] mlx5_debug_cq_add+0x5c/0xc0 [mlx5_core] [<000000002a12918f>] mlx5_core_create_cq+0x1d0/0x2d0 [mlx5_core] [<00000000cef0a696>] mlx5e_create_cq+0x210/0x3f0 [mlx5_core] [<000000009c642c26>] mlx5e_open_cq+0xb4/0x130 [mlx5_core] [<0000000058dfa578>] mlx5e_ptp_open+0x7f4/0xe10 [mlx5_core] [<0000000081839561>] mlx5e_open_channels+0x9cc/0x13e0 [mlx5_core] [<0000000009cf05d4>] mlx5e_switch_priv_channels+0xa4/0x230 [mlx5_core] [<0000000042bbedd8>] mlx5e_safe_switch_params+0x14c/0x300 [mlx5_core] [<0000000004bc9db8>] set_pflag_tx_port_ts+0x9c/0x160 [mlx5_core] [<00000000a0553443>] mlx5e_set_priv_flags+0xd0/0x1b0 [mlx5_core] [<00000000a8f3d84b>] ethnl_set_privflags+0x234/0x2d0 [<00000000fd27f27c>] genl_family_rcv_msg_doit+0x108/0x1d0 [<00000000f495e2bb>] genl_family_rcv_msg+0xe4/0x1f0 [<00000000646c5c2c>] genl_rcv_msg+0x78/0x120 [<00000000d53e384e>] netlink_rcv_skb+0x74/0x1a0 Fixes: e126ba97dba9 ("mlx5: Add driver for Mellanox Connect-IB adapters") Signed-off-by: Valentine Fatiev <valentinef(a)nvidia.com> Reviewed-by: Moshe Shemesh <moshe(a)nvidia.com> Signed-off-by: Saeed Mahameed <saeedm(a)nvidia.com> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> conficts: drivers/net/ethernet/mellanox/mlx5/core/cq.c Signed-off-by: Zheng Zucheng <zhengzucheng(a)huawei.com> --- drivers/net/ethernet/mellanox/mlx5/core/cq.c | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) diff --git a/drivers/net/ethernet/mellanox/mlx5/core/cq.c b/drivers/net/ethernet/mellanox/mlx5/core/cq.c index a4179122a279..a46962287012 100644 --- a/drivers/net/ethernet/mellanox/mlx5/core/cq.c +++ b/drivers/net/ethernet/mellanox/mlx5/core/cq.c @@ -155,6 +155,7 @@ int mlx5_core_destroy_cq(struct mlx5_core_dev *dev, struct mlx5_core_cq *cq) u32 in[MLX5_ST_SZ_DW(destroy_cq_in)] = {0}; int err; + mlx5_debug_cq_remove(dev, cq); err = mlx5_eq_del_cq(&dev->priv.eq_table.async_eq, cq); if (err) return err; @@ -166,16 +167,13 @@ int mlx5_core_destroy_cq(struct mlx5_core_dev *dev, struct mlx5_core_cq *cq) MLX5_SET(destroy_cq_in, in, opcode, MLX5_CMD_OP_DESTROY_CQ); MLX5_SET(destroy_cq_in, in, cqn, cq->cqn); err = mlx5_cmd_exec(dev, in, sizeof(in), out, sizeof(out)); - if (err) - return err; synchronize_irq(cq->irqn); - mlx5_debug_cq_remove(dev, cq); mlx5_cq_put(cq); wait_for_completion(&cq->free); - return 0; + return err; } EXPORT_SYMBOL(mlx5_core_destroy_cq); -- 2.34.1

However, if the value of port is 6 or 7, an array overflow could occur: port_rst_off = dsaf_dev->mac_cb[port]->port_rst_off; because the length of dsaf_dev->mac_cb is DSAF_MAX_PORT_NUM (i.e., 6).

During the subsequent initialization, set_power_state gets called to transition to the final power state. set_power_state refers to values from the current state and without current state populated, it could result in NULL pointer dereference. For ex: on platforms where PCI speed change is supported through ACPI ATCS method, the link speed of current state needs to be queried before deciding on changing to final power state's link speed. The logic to query ATCS-support was broken on certain platforms. The issue became visible when broken ATCS-support logic got fixed with commit f9b7f3703ff9 ("drm/amdgpu/acpi: make ATPX/ATCS structures global (v2)").

[PATCH OLK-5.10] net/mlx5: Properly link new fs rules into the tree

On the other hand, create_flow_handle tries hard to find and reference already existing identical rules instead of creating new ones. These two behaviors can result in a situation where create_flow_handle 1) creates a new rule and references it, then 2) in a subsequent step during the same handle creation references it again, resulting in a rule with a refcount of 2 that is not linked into the tree, will have a NULL parent and root and will result in a crash when the flow group is deleted because del_sw_hw_rule, invoked on rule deletion, assumes node->parent is != NULL. This happened in the wild, due to another bug related to incorrect handling of duplicate pkt_reformat ids, which lead to the code in create_flow_handle incorrectly referencing a just-added rule in the same flow handle, resulting in the problem described above.

[PATCH openEuler-1.0-LTS] tcp: fix page frag corruption on page fault
by Liu Jian 30 May '24

From: Paolo Abeni <pabeni(a)redhat.com> mainline inclusion from mainline-v5.16-rc4 commit dacb5d8875cc6cd3a553363b4d6f06760fcbe70c category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9S257 CVE: CVE-2021-47544 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… --------------------------- Steffen reported a TCP stream corruption for HTTP requests served by the apache web-server using a cifs mount-point and memory mapping the relevant file. The root cause is quite similar to the one addressed by commit 20eb4f29b602 ("net: fix sk_page_frag() recursion from memory reclaim"). Here the nested access to the task page frag is caused by a page fault on the (mmapped) user-space memory buffer coming from the cifs file. The page fault handler performs an smb transaction on a different socket, inside the same process context. Since sk->sk_allaction for such socket does not prevent the usage for the task_frag, the nested allocation modify "under the hood" the page frag in use by the outer sendmsg call, corrupting the stream. The overall relevant stack trace looks like the following: httpd 78268 [001] 3461630.850950: probe:tcp_sendmsg_locked: ffffffff91461d91 tcp_sendmsg_locked+0x1 ffffffff91462b57 tcp_sendmsg+0x27 ffffffff9139814e sock_sendmsg+0x3e ffffffffc06dfe1d smb_send_kvec+0x28 [...] ffffffffc06cfaf8 cifs_readpages+0x213 ffffffff90e83c4b read_pages+0x6b ffffffff90e83f31 __do_page_cache_readahead+0x1c1 ffffffff90e79e98 filemap_fault+0x788 ffffffff90eb0458 __do_fault+0x38 ffffffff90eb5280 do_fault+0x1a0 ffffffff90eb7c84 __handle_mm_fault+0x4d4 ffffffff90eb8093 handle_mm_fault+0xc3 ffffffff90c74f6d __do_page_fault+0x1ed ffffffff90c75277 do_page_fault+0x37 ffffffff9160111e page_fault+0x1e ffffffff9109e7b5 copyin+0x25 ffffffff9109eb40 _copy_from_iter_full+0xe0 ffffffff91462370 tcp_sendmsg_locked+0x5e0 ffffffff91462370 tcp_sendmsg_locked+0x5e0 ffffffff91462b57 tcp_sendmsg+0x27 ffffffff9139815c sock_sendmsg+0x4c ffffffff913981f7 sock_write_iter+0x97 ffffffff90f2cc56 do_iter_readv_writev+0x156 ffffffff90f2dff0 do_iter_write+0x80 ffffffff90f2e1c3 vfs_writev+0xa3 ffffffff90f2e27c do_writev+0x5c ffffffff90c042bb do_syscall_64+0x5b ffffffff916000ad entry_SYSCALL_64_after_hwframe+0x65 The cifs filesystem rightfully sets sk_allocations to GFP_NOFS, we can avoid the nesting using the sk page frag for allocation lacking the __GFP_FS flag.

[PATCH openEuler-1.0-LTS] ocfs2: fix data corruption after conversion from inline format
by Long Li 30 May '24

30 May '24

From: Jan Kara <jack(a)suse.cz> stable inclusion from stable-v4.19.213 commit a3a089c241cd49b33a8cdd7fcb37cc87a086912a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RC18 CVE: CVE-2021-47460 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… -------------------------------- commit 5314454ea3ff6fc746eaf71b9a7ceebed52888fa upstream. Commit 6dbf7bb55598 ("fs: Don't invalidate page buffers in block_write_full_page()") uncovered a latent bug in ocfs2 conversion from inline inode format to a normal inode format. The code in ocfs2_convert_inline_data_to_extents() attempts to zero out the whole cluster allocated for file data by grabbing, zeroing, and dirtying all pages covering this cluster. However these pages are beyond i_size, thus writeback code generally ignores these dirty pages and no blocks were ever actually zeroed on the disk. This oversight was fixed by commit 693c241a5f6a ("ocfs2: No need to zero pages past i_size.") for standard ocfs2 write path, inline conversion path was apparently forgotten; the commit log also has a reasoning why the zeroing actually is not needed. After commit 6dbf7bb55598, things became worse as writeback code stopped invalidating buffers on pages beyond i_size and thus these pages end up with clean PageDirty bit but with buffers attached to these pages being still dirty. So when a file is converted from inline format, then writeback triggers, and then the file is grown so that these pages become valid, the invalid dirtiness state is preserved, mark_buffer_dirty() does nothing on these pages (buffers are already dirty) but page is never written back because it is clean. So data written to these pages is lost once pages are reclaimed. Simple reproducer for the problem is: xfs_io -f -c "pwrite 0 2000" -c "pwrite 2000 2000" -c "fsync" \ -c "pwrite 4000 2000" ocfs2_file After unmounting and mounting the fs again, you can observe that end of 'ocfs2_file' has lost its contents. Fix the problem by not doing the pointless zeroing during conversion from inline format similarly as in the standard write path.

From: Dan Carpenter <dan.carpenter(a)oracle.com> stable inclusion from stable-v4.19.209 commit 66f74ba9be9daf9c47fface6af3677f602774f6b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9R4M2 CVE: CVE-2021-47361 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… --------------------------- commit 25a1433216489de4abc889910f744e952cb6dbae upstream. There are two bugs: 1) If ida_simple_get() fails then this code calls put_device(carrier) but we haven't yet called get_device(carrier) and probably that leads to a use after free. 2) After device_initialize() then we need to use put_device() to release the bus. This will free the internal resources tied to the device and call mcb_free_bus() which will free the rest.

[PATCH openEuler-22.03-LTS] s390/dasd: protect device queue against concurrent access

From: Jan Höppner <hoeppner(a)linux.ibm.com> stable inclusion from stable-v5.10.203 commit c841de6247e94e07566d57163d3c0d8b29278f7a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9R4KR CVE: CVE-2023-52774 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit db46cd1e0426f52999d50fa72cfa97fa39952885 upstream. In dasd_profile_start() the amount of requests on the device queue are counted. The access to the device queue is unprotected against concurrent access. With a lot of parallel I/O, especially with alias devices enabled, the device queue can change while dasd_profile_start() is accessing the queue. In the worst case this leads to a kernel panic due to incorrect pointer accesses. Fix this by taking the device lock before accessing the queue and counting the requests. Additionally the check for a valid profile data pointer can be done earlier to avoid unnecessary locking in a hot path.

[PATCH OLK-6.6] xfs: Fix file creation failure
by Zizhi Wo 30 May '24

30 May '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9TDTA CVE: NA -------------------------------- In the file system expansion test and concurrent file creation and writing scenarios, file creation fails occasionally. The detailed test scheme is as follows: 1. If the remaining space is less than 128 MB, expand the space by 1 GB; --xfs_growfs /$DEV -D $bc -m 100 2. 32 processes create a file every 0.5s and write 4 KB to 4 MB data randomly. --filesize=$((RANDOM % 1024 + 1)) --dd if=/dev/zero oflag=direct of=$filename bs=4K count=$filesize And when the file creation fails, there are still hundreds of megabytes of free space. The overall analysis process is as follows: Direct write Create file xfs_file_write_iter ... xfs_direct_write_iomap_begin xfs_iomap_write_direct ... xfs_alloc_ag_vextent_near xfs_alloc_cur_finish xfs_alloc_fixup_trees xfs_btree_delete xfs_btree_delrec xfs_allocbt_update_lastrec // Longest = 0 because numrec == 0. agf->agf_longest = len = 0 xfs_create ... xfs_dialloc ... xfs_alloc_fix_freelist xfs_alloc_space_available -> as longest=0, it will return false, no space for inode alloc. The root cause of the problem is that allocation extents holds agf locks, but the inode creation process will quickly check whether there is space firstly, which does not have agf locks. And when the first judgment fails, it returns directly. If the first judgment passes, the lock is held before entering the second judgment, that's how the "check-lock-check again" algorithm is designed. If all AG fails in no lock check, an error will return. This problem occurs probably when there is not enough space left for all the AG's in front, and the last AG deletes the last CNT tree record and the new record is not inserted yet. Fix this issue by adding the bc_free_longest field to the xfs_btree_cur_t structure to store the longest count that will be updated. The assignment is done in xfs_alloc_fixup_trees() and xfs_free_ag_extent().

[PATCH openEuler-1.0-LTS] mac80211: fix use-after-free in CCMP/GCMP RX
by Li Huafei 30 May '24

From: Johannes Berg <johannes.berg(a)intel.com> stable inclusion from stable-v4.19.209 commit 3d5d629c99c468458022e9b381789de3595bf4dd category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9R4NV CVE: CVE-2021-47388 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 94513069eb549737bcfc3d988d6ed4da948a2de8 upstream. When PN checking is done in mac80211, for fragmentation we need to copy the PN to the RX struct so we can later use it to do a comparison, since commit bf30ca922a0c ("mac80211: check defrag PN against current frame"). Unfortunately, in that commit I used the 'hdr' variable without it being necessarily valid, so use-after-free could occur if it was necessary to reallocate (parts of) the frame. Fix this by reloading the variable after the code that results in the reallocations, if any. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=214401.

[PATCH openEuler-1.0-LTS] s390/dasd: protect device queue against concurrent access
by Liu Shixin 30 May '24

30 May '24

From: Jan Höppner <hoeppner(a)linux.ibm.com> stable inclusion from stable-v4.19.301 commit f75617cc8df4155374132f0b500b0b3ebb967458 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9R4KR CVE: CVE-2023-52774 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit db46cd1e0426f52999d50fa72cfa97fa39952885 upstream. In dasd_profile_start() the amount of requests on the device queue are counted. The access to the device queue is unprotected against concurrent access. With a lot of parallel I/O, especially with alias devices enabled, the device queue can change while dasd_profile_start() is accessing the queue. In the worst case this leads to a kernel panic due to incorrect pointer accesses. Fix this by taking the device lock before accessing the queue and counting the requests. Additionally the check for a valid profile data pointer can be done earlier to avoid unnecessary locking in a hot path.

From: Paolo Abeni <pabeni(a)redhat.com> mainline inclusion from mainline-v5.15-rc3 commit 977d293e23b48a1129830d7968605f61c4af71a0 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9R4NZ CVE: CVE-2021-47370 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Due to signed/unsigned comparison, the expression: info->size_goal - skb->len > 0 evaluates to true when the size goal is smaller than the skb size.

The error handing will call cpuhp_state_remove_instance() to call uncore pmu offline callback, which migrate the pmu context. Since that's liable to lead to some kind of use-after-free. Use cpuhp_state_remove_instance_nocalls() instead of cpuhp_state_remove_instance() so that the notifiers don't execute after the PMU device has been failed to register.

[PATCH openEuler-1.0-LTS] ipvlan: add ipvlan_route_v6_outbound() helper
by Zhengchao Shao 30 May '24

30 May '24

From: Eric Dumazet <edumazet(a)google.com> stable inclusion from stable-v4.19.300 commit 4f7f850611aa27aaaf1bf5687702ad2240ae442a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RFH5 CVE: CVE-2023-52796 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 18f039428c7df183b09c69ebf10ffd4e521035d2 ] Inspired by syzbot reports using a stack of multiple ipvlan devices. Reduce stack size needed in ipvlan_process_v6_outbound() by moving the flowi6 struct used for the route lookup in an non inlined helper. ipvlan_route_v6_outbound() needs 120 bytes on the stack, immediately reclaimed. Also make sure ipvlan_process_v4_outbound() is not inlined. We might also have to lower MAX_NEST_DEV, because only syzbot uses setups with more than four stacked devices. BUG: TASK stack guard page was hit at ffffc9000e803ff8 (stack is ffffc9000e804000..ffffc9000e808000) stack guard page: 0000 [#1] SMP KASAN CPU: 0 PID: 13442 Comm: syz-executor.4 Not tainted

[PATCH openEuler-1.0-LTS] tty: fix hang on tty device with no_room set
by Yi Yang 30 May '24

30 May '24

From: Hui Li <caelli(a)tencent.com> mainline inclusion from mainline-v6.5-rc1 commit 4903fde8047a28299d1fc79c1a0dcc255e928f12 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9T85S Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- It is possible to hang pty devices in this case, the reader was blocking at epoll on master side, the writer was sleeping at wait_woken inside n_tty_write on slave side, and the write buffer on tty_port was full, we found that the reader and writer would never be woken again and blocked forever. The problem was caused by a race between reader and kworker: n_tty_read(reader): n_tty_receive_buf_common(kworker): copy_from_read_buf()| |room = N_TTY_BUF_SIZE - (ldata->read_head - tail) |room <= 0 n_tty_kick_worker() | |ldata->no_room = true After writing to slave device, writer wakes up kworker to flush data on tty_port to reader, and the kworker finds that reader has no room to store data so room <= 0 is met. At this moment, reader consumes all the data on reader buffer and calls n_tty_kick_worker to check ldata->no_room which is false and reader quits reading. Then kworker sets ldata->no_room=true and quits too. If write buffer is not full, writer will wake kworker to flush data again after following writes, but if write buffer is full and writer goes to sleep, kworker will never be woken again and tty device is blocked. This problem can be solved with a check for read buffer size inside n_tty_receive_buf_common, if read buffer is empty and ldata->no_room is true, a call to n_tty_kick_worker is necessary to keep flushing data to reader.

[PATCH OLK-5.10] ipvlan: add ipvlan_route_v6_outbound() helper
by Zhengchao Shao 30 May '24

30 May '24

From: Eric Dumazet <edumazet(a)google.com> stable inclusion from stable-v5.10.202 commit 43b781e7cb5cd0b435de276111953bf2bacd1f02 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RFH5 CVE: CVE-2023-52796 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 18f039428c7df183b09c69ebf10ffd4e521035d2 ] Inspired by syzbot reports using a stack of multiple ipvlan devices. Reduce stack size needed in ipvlan_process_v6_outbound() by moving the flowi6 struct used for the route lookup in an non inlined helper. ipvlan_route_v6_outbound() needs 120 bytes on the stack, immediately reclaimed. Also make sure ipvlan_process_v4_outbound() is not inlined. We might also have to lower MAX_NEST_DEV, because only syzbot uses setups with more than four stacked devices.

[PATCH OLK-5.10] xfs: Fix file creation failure
by Zizhi Wo 30 May '24

30 May '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9TDTA CVE: NA -------------------------------- In the file system expansion test and concurrent file creation and writing scenarios, file creation fails occasionally. The detailed test scheme is as follows: 1. If the remaining space is less than 128 MB, expand the space by 1 GB; --xfs_growfs /$DEV -D $bc -m 100 2. 32 processes create a file every 0.5s and write 4 KB to 4 MB data randomly. --filesize=$((RANDOM % 1024 + 1)) --dd if=/dev/zero oflag=direct of=$filename bs=4K count=$filesize And when the file creation fails, there are still hundreds of megabytes of free space. The overall analysis process is as follows: Direct write Create file xfs_file_write_iter ... xfs_direct_write_iomap_begin xfs_iomap_write_direct ... xfs_alloc_vextent xfs_alloc_ag_vextent xfs_alloc_ag_vextent_near xfs_alloc_cur_finish xfs_alloc_fixup_trees xfs_btree_delete xfs_btree_delrec xfs_allocbt_update_lastrec /* The longest update is 0 * because numrec == 0. */ agf->agf_longest = len = 0 xfs_create ... xfs_dialloc xfs_ialloc_ag_alloc xfs_alloc_vextent xfs_alloc_fix_freelist xfs_alloc_space_available -> as longest=0, it will return false, no space for inode alloc. The root cause of the problem is that allocation extents holds agf locks, but the inode creation process will quickly check whether there is space firstly, which does not have agf locks. And when the first judgment fails, it returns directly. If the first judgment passes, the lock is held before entering the second judgment, that's how the "check-lock-check again" algorithm is designed. If all AG fails in no lock check, an error will return. This problem occurs probably when there is not enough space left for all the AG's in front, and the last AG deletes the last CNT tree record and the new record is not inserted yet. Fix this issue by adding the bc_free_longest field to the xfs_btree_cur_t structure to store the longest count that will be updated. The assignment is done in xfs_alloc_fixup_trees() and xfs_free_ag_extent().

[PATCH openEuler-1.0-LTS v2] powerpc/mm: Fix lockup on kernel exec fault
by Liu Shixin 30 May '24

30 May '24

From: Christophe Leroy <christophe.leroy(a)csgroup.eu> stable inclusion from stable-v5.4.133 commit a82471a14aad90f79d1608d2bcbb019f0ffb53f0 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9R4CI CVE: CVE-2021-47350 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit cd5d5e602f502895e47e18cd46804d6d7014e65c upstream. The powerpc kernel is not prepared to handle exec faults from kernel. Especially, the function is_exec_fault() will return 'false' when an exec fault is taken by kernel, because the check is based on reading current->thread.regs->trap which contains the trap from user. For instance, when provoking a LKDTM EXEC_USERSPACE test, current->thread.regs->trap is set to SYSCALL trap (0xc00), and the fault taken by the kernel is not seen as an exec fault by set_access_flags_filter(). Commit d7df2443cd5f ("powerpc/mm: Fix spurious segfaults on radix with autonuma") made it clear and handled it properly. But later on commit d3ca587404b3 ("powerpc/mm: Fix reporting of kernel execute faults") removed that handling, introducing test based on error_code. And here is the problem, because on the 603 all upper bits of SRR1 get cleared when the TLB instruction miss handler bails out to ISI. Until commit cbd7e6ca0210 ("powerpc/fault: Avoid heavy search_exception_tables() verification"), an exec fault from kernel at a userspace address was indirectly caught by the lack of entry for that address in the exception tables. But after that commit the kernel mainly relies on KUAP or on core mm handling to catch wrong user accesses. Here the access is not wrong, so mm handles it. It is a minor fault because PAGE_EXEC is not set, set_access_flags_filter() should set PAGE_EXEC and voila. But as is_exec_fault() returns false as explained in the beginning, set_access_flags_filter() bails out without setting PAGE_EXEC flag, which leads to a forever minor exec fault. As the kernel is not prepared to handle such exec faults, the thing to do is to fire in bad_kernel_fault() for any exec fault taken by the kernel, as it was prior to commit d3ca587404b3.

[PATCH openEuler-1.0-LTS] netfilter: conntrack: serialize hash resizes and cleanups
by Liu Jian 30 May '24

30 May '24

From: Eric Dumazet <edumazet(a)google.com> mainline inclusion from mainline-v5.15-rc4 commit e9edc188fc76499b0b9bd60364084037f6d03773 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9R4NQ CVE: CVE-2021-47408 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… --------------------------- Syzbot was able to trigger the following warning [1] No repro found by syzbot yet but I was able to trigger similar issue by having 2 scripts running in parallel, changing conntrack hash sizes, and: for j in `seq 1 1000` ; do unshare -n /bin/true >/dev/null ; done It would take more than 5 minutes for net_namespace structures to be cleaned up. This is because nf_ct_iterate_cleanup() has to restart everytime a resize happened. By adding a mutex, we can serialize hash resizes and cleanups and also make get_next_corpse() faster by skipping over empty buckets. Even without resizes in the picture, this patch considerably speeds up network namespace dismantles.
