[PATCH openEuler-OLK-6.6 001/129] iommu/arm-smmu-v3: Make STE programming independent of the callers
by Kunkun Jiang 17 Nov '24

17 Nov '24

From: Jason Gunthorpe <jgg(a)nvidia.com> mainline inclusion from mainline-v6.9-rc1 commit 7da51af9125c624318c8099de13c5ddefd47e9e8 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IB4WDJ CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- As the comment in arm_smmu_write_strtab_ent() explains, this routine has been limited to only work correctly in certain scenarios that the caller must ensure. Generally the caller must put the STE into ABORT or BYPASS before attempting to program it to something else. The iommu core APIs would ideally expect the driver to do a hitless change of iommu_domain in a number of cases: - RESV_DIRECT support wants IDENTITY -> DMA -> IDENTITY to be hitless for the RESV ranges - PASID upgrade has IDENTIY on the RID with no PASID then a PASID paging domain installed. The RID should not be impacted - PASID downgrade has IDENTIY on the RID and all PASID's removed. The RID should not be impacted - RID does PAGING -> BLOCKING with active PASID, PASID's should not be impacted - NESTING -> NESTING for carrying all the above hitless cases in a VM into the hypervisor. To comprehensively emulate the HW in a VM we should assume the VM OS is running logic like this and expecting hitless updates to be relayed to real HW. For CD updates arm_smmu_write_ctx_desc() has a similar comment explaining how limited it is, and the driver does have a need for hitless CD updates: - SMMUv3 BTM S1 ASID re-label - SVA mm release should change the CD to answert not-present to all requests without allowing logging (EPD0) The next patches/series are going to start removing some of this logic from the callers, and add more complex state combinations than currently. At the end everything that can be hitless will be hitless, including all of the above. Introduce arm_smmu_write_ste() which will run through the multi-qword programming sequence to avoid creating an incoherent 'torn' STE in the HW caches. It automatically detects which of two algorithms to use: 1) The disruptive V=0 update described in the spec which disrupts the entry and does three syncs to make the change: - Write V=0 to QWORD 0 - Write the entire STE except QWORD 0 - Write QWORD 0 2) A hitless update algorithm that follows the same rational that the driver already uses. It is safe to change IGNORED bits that HW doesn't use: - Write the target value into all currently unused bits - Write a single QWORD, this makes the new STE live atomically - Ensure now unused bits are 0 The detection of which path to use and the implementation of the hitless update rely on a "used bitmask" describing what bits the HW is actually using based on the V/CFG/etc bits. This flows from the spec language, typically indicated as IGNORED. Knowing which bits the HW is using we can update the bits it does not use and then compute how many QWORDS need to be changed. If only one qword needs to be updated the hitless algorithm is possible. Later patches will include CD updates in this mechanism so make the implementation generic using a struct arm_smmu_entry_writer and struct arm_smmu_entry_writer_ops to abstract the differences between STE and CD to be plugged in. At this point it generates the same sequence of updates as the current code, except that zeroing the VMID on entry to BYPASS/ABORT will do an extra sync (this seems to be an existing bug). Going forward this will use a V=0 transition instead of cycling through ABORT if a hitfull change is required. This seems more appropriate as ABORT will fail DMAs without any logging, but dropping a DMA due to transient V=0 is probably signaling a bug, so the C_BAD_STE is valuable. Add STRTAB_STE_1_SHCFG_INCOMING to s2_cfg, this was editing the STE in place and subtly inherited the value of data[1] from abort/bypass.

[PATCH OLK-6.6] arm64: Introduce xcall a faster svc exception handling
by Yipeng Zou 15 Nov '24

15 Nov '24

hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IB4PY5 ---------------------------------------- The svc exception handling process in ARM64, which includes auxiliary functions for debug/trace and core functions like KPTI, has been identified as overly "lengthy". This inefficiency is particularly noticeable in short syscalls such as lseek() and getpid(), where the syscall function itself comprises a small percentage of the total instructions executed. To address this, we introduce the concept of xcall, a fast svc exception handling path that only considers necessary features such as security, context saving, and recovery. This approach can be seen as a high-speed syscall processing mechanism bridging the gap between vdso and traditional syscalls. We've implemented a per-task bitmap to enable or disable xcall for specific syscalls. Users can enable a syscall with the following command: echo $syscall_nr > /proc/$PID/xcall To disable a syscall, use: echo \!$syscall_nr > /proc/$PID/xcall The current status of enabled syscalls can be viewed by: cat /proc/$PID/xcall Finally, we've added a kernel boot parameter to control the xcall feature. To enable xcall, include "xcall" in the kernel boot command. By default, xcall is disabled.

[PATCH OLK-6.6] bpf: Zero former ARG_PTR_TO_{LONG,INT} args in case of error
by Liu Jian 15 Nov '24

15 Nov '24

From: Daniel Borkmann <daniel(a)iogearbox.net> stable inclusion from stable-v6.6.54 commit a634fa8e480ac2423f86311a602f6295df2c8ed0 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAYQSD CVE: CVE-2024-47728 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 4b3786a6c5397dc220b1483d8e2f4867743e966f ] For all non-tracing helpers which formerly had ARG_PTR_TO_{LONG,INT} as input arguments, zero the value for the case of an error as otherwise it could leak memory. For tracing, it is not needed given CAP_PERFMON can already read all kernel memory anyway hence bpf_get_func_arg() and bpf_get_func_ret() is skipped in here. Also, the MTU helpers mtu_len pointer value is being written but also read. Technically, the MEM_UNINIT should not be there in order to always force init. Removing MEM_UNINIT needs more verifier rework though: MEM_UNINIT right now implies two things actually: i) write into memory, ii) memory does not have to be initialized. If we lift MEM_UNINIT, it then becomes: i) read into memory, ii) memory must be initialized. This means that for bpf_*_check_mtu() we're readding the issue we're trying to fix, that is, it would then be able to write back into things like .rodata BPF maps. Follow-up work will rework the MEM_UNINIT semantics such that the intent can be better expressed. For now just clear the *mtu_len on error path which can be lifted later again.

[PATCH OLK-5.10] RDMA/hns: Fix the valid QP bank set to improve performance
by Chengchang Tang 14 Nov '24

14 Nov '24

From: wenglianfa <wenglianfa(a)huawei.com> driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB2HJE ---------------------------------------------------------------------- QP banks 0, 1, 4, and 5 use one HW FIFO, while QP banks 2, 3, 6, and 7 use another. Currently, if HNS_ROCE_CAP_FLAG_LIMIT_BANK is set, only QP banks 0, 1, 4, and 5 are used, resulting in a single HW FIFO being utilized. Instead, it is proposed to use QP banks 0, 1, 6, and 7 to leverage different FIFOs and improve performance.

[PATCH openEuler-1.0-LTS] sched/dynamic_affinity: fix preffered_cpu offline problem
by He Yujie 14 Nov '24

14 Nov '24

Offering: HULK hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB42TC -------------------------------- After the preferred_cpu goes offline, the core selection of dynamic affinity does not check whether the preferred_cpu is valid. As a result, related dynamic affinity processes are concentrated on a shared_cpu. This patch resolves this problem to checks whether the preferred_cpu is valid and compares only the usage threshold of the valid preferred_cpu.

[PATCH OLK-5.10 V1] scsi: pm80xx: Set phy->enable_completion only when we wait for it

From: Igor Pylypiv <ipylypiv(a)google.com> stable inclusion from stable-v6.6.51 commit 7b1d779647afaea9185fa2f150b1721e7c1aae89 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAVU94 CVE: CVE-2024-47666 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit e4f949ef1516c0d74745ee54a0f4882c1f6c7aea ] pm8001_phy_control() populates the enable_completion pointer with a stack address, sends a PHY_LINK_RESET / PHY_HARD_RESET, waits 300 ms, and returns. The problem arises when a phy control response comes late. After 300 ms the pm8001_phy_control() function returns and the passed enable_completion stack address is no longer valid. Late phy control response invokes complete() on a dangling enable_completion pointer which leads to a kernel crash.

[PATCH OLK-5.10] xfs: Fix missing interval for missing_owner in xfs fsmap

BUG: [root@fedora ~]# xfs_io -c 'fsmap -vvvv -d 104 107' /mnt [root@fedora ~]# Normally, we should be able to get [104, 107), but we got nothing. The problem is caused by shifting. The query for the problem-triggered scenario is for the missing_owner interval (e.g. freespace in rmapbt/ unknown space in bnobt), which is obtained by subtraction (gap). For this scenario, the interval is obtained by info->last. However, rec_daddr is calculated based on the start_block recorded in key[1], which is converted by calling XFS_BB_TO_FSBT. Then if rec_daddr does not exceed info->next_daddr, which means keys[1].fmr_physical >> (mp)->m_blkbb_log <= info->next_daddr, no records will be displayed. In the above example, 104 >> (mp)->m_blkbb_log = 12 and 107 >> (mp)->m_blkbb_log = 12, so the two are reduced to 0 and the gap is ignored: before calculate ----------------> after shifting 104(st) 107(ed) 12(st/ed) |---------| | sector size block size Resolve this issue by introducing the "end_daddr" field in xfs_getfsmap_info. This records |key[1].fmr_physical + key[1].length| at the granularity of sector. If the current query is the last, the rec_daddr is end_daddr to prevent missing interval problems caused by shifting. We only need to focus on the last query, because xfs disks are internally aligned with disk blocksize that are powers of two and minimum 512, so there is no problem with shifting in previous queries. After applying this patch, the above problem have been solved: [root@fedora ~]# xfs_io -c 'fsmap -vvvv -d 104 107' /mnt EXT: DEV BLOCK-RANGE OWNER FILE-OFFSET AG AG-OFFSET TOTAL 0: 253:16 [104..106]: free space 0 (104..106) 3 Fixes: e89c041338ed ("xfs: implement the GETFSMAP ioctl") Signed-off-by: Zizhi Wo <wozizhi(a)huawei.com> Reviewed-by: Darrick J.

In ad9834_write_frequency() clk_get_rate() can return 0. In such case ad9834_calc_freqreg() call will lead to division by zero. Checking 'if (fout > (clk_freq / 2))' doesn't protect in case of 'fout' is 0. ad9834_write_frequency() is called from ad9834_write(), where fout is taken from text buffer, which can contain any value.

BUG: [root@fedora ~]# xfs_io -c 'fsmap -vvvv -d 104 107' /mnt [root@fedora ~]# Normally, we should be able to get [104, 107), but we got nothing. The problem is caused by shifting. The query for the problem-triggered scenario is for the missing_owner interval (e.g. freespace in rmapbt/ unknown space in bnobt), which is obtained by subtraction (gap). For this scenario, the interval is obtained by info->last. However, rec_daddr is calculated based on the start_block recorded in key[1], which is converted by calling XFS_BB_TO_FSBT. Then if rec_daddr does not exceed info->next_daddr, which means keys[1].fmr_physical >> (mp)->m_blkbb_log <= info->next_daddr, no records will be displayed. In the above example, 104 >> (mp)->m_blkbb_log = 12 and 107 >> (mp)->m_blkbb_log = 12, so the two are reduced to 0 and the gap is ignored: before calculate ----------------> after shifting 104(st) 107(ed) 12(st/ed) |---------| | sector size block size Resolve this issue by introducing the "end_daddr" field in xfs_getfsmap_info. This records |key[1].fmr_physical + key[1].length| at the granularity of sector. If the current query is the last, the rec_daddr is end_daddr to prevent missing interval problems caused by shifting. We only need to focus on the last query, because xfs disks are internally aligned with disk blocksize that are powers of two and minimum 512, so there is no problem with shifting in previous queries. After applying this patch, the above problem have been solved: [root@fedora ~]# xfs_io -c 'fsmap -vvvv -d 104 107' /mnt EXT: DEV BLOCK-RANGE OWNER FILE-OFFSET AG AG-OFFSET TOTAL 0: 253:16 [104..106]: free space 0 (104..106) 3 Fixes: e89c041338ed ("xfs: implement the GETFSMAP ioctl") Signed-off-by: Zizhi Wo <wozizhi(a)huawei.com> Reviewed-by: Darrick J.

In ad9834_write_frequency() clk_get_rate() can return 0. In such case ad9834_calc_freqreg() call will lead to division by zero.

From: Aleksandr Mishin <amishin(a)t-argos.ru> stable inclusion from stable-v5.10.226 commit 41cc91e3138fe52f8da92a81bebcd0e6cf488c53 category: bugfix bugzilla: IAVU8A CVE: CVE-2024-47663 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit b48aa991758999d4e8f9296c5bbe388f293ef465 upstream. In ad9834_write_frequency() clk_get_rate() can return 0. In such case ad9834_calc_freqreg() call will lead to division by zero. Checking 'if (fout > (clk_freq / 2))' doesn't protect in case of 'fout' is 0. ad9834_write_frequency() is called from ad9834_write(), where fout is taken from text buffer, which can contain any value.

[PATCH v7 OLK-5.10 0/3] arm64: support page mapping percpu first chunk allocator
by Kaixiong Yu 13 Nov '24

13 Nov '24

Percpu embedded first chunk allocator is the firstly option, but it could fails on ARM64 when turning on numa with CONFIG_KASAN=y. Let's implement page mapping percpu first chunk allocator as a fallback to the embedding allocator to increase the robustness of the system. Also fix a crash when both NEED_PER_CPU_PAGE_FIRST_CHUNK and KASAN_VMALLOC enabled. After merging this patch set, the ARM64 machine can start and work normally.

Align with the original variables to prevent others from inserting new variables before is_check in the future. V3: Add a mainline patch to fix commit 4759ff71f23e(exec: __FMODE_EXEC instead of in_execve for LSMs).

[PATCH openEuler-1.0-LTS] irqchip/i8259: Fix shutdown order by moving syscore_ops registration
by Zhang Kunbo 13 Nov '24

13 Nov '24

From: Aaro Koskinen <aaro.koskinen(a)iki.fi> mainline inclusion from mainline-v5.1-rc1 commit 518bfe84ec417318b2470652cdb27978ddfeaa59 category: bugfix bugzilla: 190379 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- When using cpufreq on Loongson 2F MIPS platform, "poweroff" command gets frequently stuck in syscore_shutdown(). The reason is that i8259A_shutdown() gets called before cpufreq_suspend(), and if we have pending work then irq_work_sync() in cpufreq_dbs_governor_stop() gets stuck forever as we have all interrupts masked already. irq-i8259 is registering syscore_ops using device_initcall(), while cpufreq uses core_initcall(). Fix the shutdown order simply by registering the irq syscore_ops during the early IRQ init instead of using a separate initcall at later stage.

[PATCH OLK-6.6 0/6] Script execution control
by Gu Bowen 13 Nov '24

13 Nov '24

Ensure that direct file execution (e.g. ./script.sh) and indirect file execution (e.g. sh script.sh) lead to the same result to support script protection. Gu Bowen (2): IMA support script execution check fix kabi breakage due to exec is_check Kees Cook (1): exec: Check __FMODE_EXEC instead of in_execve for LSMs Linus Torvalds (2): execve: open the executable file before doing anything else uselib: remove use of __FMODE_EXEC Mickaël Salaün (1): exec: Add a new AT_CHECK flag to execveat(2) V2: Add a new patch to fix kabi breakage. Align with the original variables to prevent others from inserting new variables before is_check in the future. V3: Add a mainline patch to fix commit 4759ff71f23e(exec: __FMODE_EXEC instead of in_execve for LSMs). V4: Since openEuler has a more standardised way of using KABI_FILL_HOLE to fix kabi breakage, replace it. fs/exec.c | 89 ++++++++++++++++++------------- include/linux/binfmts.h | 5 ++ include/linux/ima.h | 1 + include/uapi/linux/fcntl.h | 31 +++++++++++ kernel/audit.h | 1 + kernel/auditsc.c | 1 + security/apparmor/lsm.c | 4 +- security/integrity/ima/ima_main.c | 11 ++++ security/security.c | 17 +++++- security/tomoyo/tomoyo.c | 3 +- 10 files changed, 123 insertions(+), 40 deletions(-) -- 2.25.1

The dev pointer that is received as an argument in the in_illuminance_period_available_show function references the device embedded in the IIO device, not in the i2c client. dev_to_iio_dev() must be used to accessthe right data. The current implementation leads to a segmentation fault on every attempt to read the attribute because indio_dev gets a NULL assignment. This bug has been present since the first appearance of the driver, apparently since the last version (V6) before getting applied. A constant attribute was used until then, and the last modifications might have not been tested again.

[PATCH openEuler-1.0-LTS] serial: core: Fix atomicity violation in uart_tiocmget
by Yi Yang 12 Nov '24

12 Nov '24

From: Gui-Dong Han <2045gemini(a)gmail.com> mainline inclusion from mainline-v6.8-rc3 commit 30926783a46841c2d1bbf3f74067ba85d304fd0d category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB1MRY CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- In uart_tiocmget(): result = uport->mctrl; uart_port_lock_irq(uport); result |= uport->ops->get_mctrl(uport); uart_port_unlock_irq(uport); ... return result; In uart_update_mctrl(): uart_port_lock_irqsave(port, &flags); ... port->mctrl = (old & ~clear) | set; ... port->ops->set_mctrl(port, port->mctrl); ... uart_port_unlock_irqrestore(port, flags); An atomicity violation is identified due to the concurrent execution of uart_tiocmget() and uart_update_mctrl(). After assigning result = uport->mctrl, the mctrl value may change in uart_update_mctrl(), leading to a mismatch between the value returned by uport->ops->get_mctrl(uport) and the mctrl value previously read. This can result in uart_tiocmget() returning an incorrect value. This possible bug is found by an experimental static analysis tool developed by our team, BassCheck[1]. This tool analyzes the locking APIs to extract function pairs that can be concurrently executed, and then analyzes the instructions in the paired functions to identify possible concurrency bugs including data races and atomicity violations. The above possible bug is reported when our tool analyzes the source code of Linux 5.17. To address this issue, it is suggested to move the line result = uport->mctrl inside the uart_port_lock block to ensure atomicity and prevent the mctrl value from being altered during the execution of uart_tiocmget(). With this patch applied, our tool no longer reports the bug, with the kernel configuration allyesconfig for x86_64. Due to the absence of the requisite hardware, we are unable to conduct runtime testing of the patch. Therefore, our verification is solely based on code logic analysis.

[PATCH openEuler-1.0-LTS v3] sched: smart_grid: Prevent double-free in sched_grid_qos_free
by Yipeng Zou 12 Nov '24

12 Nov '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB3N2A ---------------------------------------- KASAN detected a double-free bug in the smart grid. This issue arises from the uninitialized use of p->grid_qos within the task {fork,free} processes. The sequence of events leading to the double-free is as follows: CPU0 CPU1 fork (in some error process) goto bad_fork_free call_rcu(__delayed_free_task) __delayed_free_task sched_grid_qos_free realse_task delayed_put_task_struct __put_task_struct sched_grid_qos_free(double free) When copy_process returns with an error, grid_qos is double-freed. To address this, grid_qos is initialized to NULL in dup_task_struct, and a NULL check is added for p->grid_qos before freeing.

[PATCH OLK-6.6] drm/msm: Avoid NULL dereference in msm_disp_state_print_regs()
by Liu Mingrui 12 Nov '24

12 Nov '24

From: Douglas Anderson <dianders(a)chromium.org> mainline inclusion from mainline-v6.12-rc4 commit 293f53263266bc4340d777268ab4328a97f041fa category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB2STZ CVE: CVE-2024-50156 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- If the allocation in msm_disp_state_dump_regs() failed then `block->state` can be NULL. The msm_disp_state_print_regs() function _does_ have code to try to handle it with: if (*reg) dump_addr = *reg; ...but since "dump_addr" is initialized to NULL the above is actually a noop. The code then goes on to dereference `dump_addr`. Make the function print "Registers not stored" when it sees a NULL to solve this. Since we're touching the code, fix msm_disp_state_print_regs() not to pointlessly take a double-pointer and properly mark the pointer as `const`.

[PATCH v6 OLK-5.10 0/3] arm64: support page mapping percpu first chunk allocator
by Kaixiong Yu 12 Nov '24

12 Nov '24

Percpu embedded first chunk allocator is the firstly option, but it could fails on ARM64 when turning on numa with CONFIG_KASAN=y. Let's implement page mapping percpu first chunk allocator as a fallback to the embedding allocator to increase the robustness of the system. Also fix a crash when both NEED_PER_CPU_PAGE_FIRST_CHUNK and KASAN_VMALLOC enabled. After merging this patch set, the ARM64 machine can start and work normally.

[PATCH OLK-5.10] sched: smart_grid: Prevent double-free in sched_grid_qos_free
by Yipeng Zou 12 Nov '24

12 Nov '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB3N2A ---------------------------------------- KASAN detected a double-free bug in the smart grid. This issue arises from the uninitialized use of p->grid_qos within the task {fork,free} processes. The sequence of events leading to the double-free is as follows: CPU0 CPU1 fork (in some error process) goto bad_fork_free call_rcu(__delayed_free_task) __delayed_free_task sched_grid_qos_free realse_task delayed_put_task_struct __put_task_struct sched_grid_qos_free(double free) When copy_process returns with an error, grid_qos is double-freed. To address this, grid_qos is initialized to NULL in dup_task_struct, and a NULL check is added for p->grid_qos before freeing.

From: Srinivasan Shanmugam <srinivasan.shanmugam(a)amd.com> stable inclusion from stable-v6.11.3 commit 65a6fee22d5cfa645cb05489892dc9cd3d142fc2 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYRAY CVE: CVE-2024-49914 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 8e4ed3cf1642df0c4456443d865cff61a9598aa8 ] This commit addresses a null pointer dereference issue in the `dcn20_program_pipe` function. The issue could occur when `pipe_ctx->plane_state` is null. The fix adds a check to ensure `pipe_ctx->plane_state` is not null before accessing. This prevents a null pointer dereference.

[PATCH openEuler-1.0-LTS] security/keys: fix slab-out-of-bounds in key_task_permission

It can be reproduced by following these steps(more details [1]): 1. Obtain more than 32 inputs that have similar hashes, which ends with the pattern '0xxxxxxxe6'. 2. Reboot and add the keys obtained in step 1. The reproducer demonstrates how this issue happened: 1. In the search_nested_keyrings function, when it iterates through the slots in a node(below tag ascend_to_node), if the slot pointer is meta and node->back_pointer != NULL(it means a root), it will proceed to descend_to_node. However, there is an exception. If node is the root, and one of the slots points to a shortcut, it will be treated as a keyring. 2. Whether the ptr is keyring decided by keyring_ptr_is_keyring function. However, KEYRING_PTR_SUBTYPE is 0x2UL, the same as ASSOC_ARRAY_PTR_SUBTYPE_MASK. 3. When 32 keys with the similar hashes are added to the tree, the ROOT has keys with hashes that are not similar (e.g. slot 0) and it splits NODE A without using a shortcut. When NODE A is filled with keys that all hashes are xxe6, the keys are similar, NODE A will split with a shortcut. Finally, it forms the tree as shown below, where slot 6 points to a shortcut. NODE A +------>+---+ ROOT | | 0 | xxe6 +---+ | +---+ xxxx | 0 | shortcut : : xxe6 +---+ | +---+ xxe6 : : | | | xxe6 +---+ | +---+ | 6 |---+ : : xxe6 +---+ +---+ xxe6 : : | f | xxe6 +---+ +---+ xxe6 | f | +---+ 4. As mentioned above, If a slot(slot 6) of the root points to a shortcut, it may be mistakenly transferred to a key*, leading to a read out-of-bounds read. To fix this issue, one should jump to descend_to_node if the ptr is a shortcut, regardless of whether the node is root or not.

[PATCH OLK-5.10] arm64: probes: Remove broken LDR (literal) uprobe support
by Chen Zhongjin 11 Nov '24

11 Nov '24

From: Mark Rutland <mark.rutland(a)arm.com> stable inclusion from stable-v5.10.228 commit 3728b4eb27910ffedd173018279a970705f2e03a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB2BX7 CVE: CVE-2024-50099 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- commit acc450aa07099d071b18174c22a1119c57da8227 upstream. The simulate_ldr_literal() and simulate_ldrsw_literal() functions are unsafe to use for uprobes. Both functions were originally written for use with kprobes, and access memory with plain C accesses. When uprobes was added, these were reused unmodified even though they cannot safely access user memory. There are three key problems: 1) The plain C accesses do not have corresponding extable entries, and thus if they encounter a fault the kernel will treat these as unintentional accesses to user memory, resulting in a BUG() which will kill the kernel thread, and likely lead to further issues (e.g. lockup or panic()). 2) The plain C accesses are subject to HW PAN and SW PAN, and so when either is in use, any attempt to simulate an access to user memory will fault. Thus neither simulate_ldr_literal() nor simulate_ldrsw_literal() can do anything useful when simulating a user instruction on any system with HW PAN or SW PAN. 3) The plain C accesses are privileged, as they run in kernel context, and in practice can access a small range of kernel virtual addresses. The instructions they simulate have a range of +/-1MiB, and since the simulated instructions must itself be a user instructions in the TTBR0 address range, these can address the final 1MiB of the TTBR1 acddress range by wrapping downwards from an address in the first 1MiB of the TTBR0 address range. In contemporary kernels the last 8MiB of TTBR1 address range is reserved, and accesses to this will always fault, meaning this is no worse than (1). Historically, it was theoretically possible for the linear map or vmemmap to spill into the final 8MiB of the TTBR1 address range, but in practice this is extremely unlikely to occur as this would require either: * Having enough physical memory to fill the entire linear map all the way to the final 1MiB of the TTBR1 address range. * Getting unlucky with KASLR randomization of the linear map such that the populated region happens to overlap with the last 1MiB of the TTBR address range. ... and in either case if we were to spill into the final page there would be larger problems as the final page would alias with error pointers. Practically speaking, (1) and (2) are the big issues. Given there have been no reports of problems since the broken code was introduced, it appears that no-one is relying on probing these instructions with uprobes. Avoid these issues by not allowing uprobes on LDR (literal) and LDRSW (literal), limiting the use of simulate_ldr_literal() and simulate_ldrsw_literal() to kprobes. Attempts to place uprobes on LDR (literal) and LDRSW (literal) will be rejected as arm_probe_decode_insn() will return INSN_REJECTED. In future we can consider introducing working uprobes support for these instructions, but this will require more significant work.

[PATCH OLK-6.6] nvmet-auth: assign dh_key to NULL after kfree_sensitive
by Li Huafei 11 Nov '24

11 Nov '24

From: Vitaliy Shevtsov <v.shevtsov(a)maxima.ru> stable inclusion from stable-v6.6.60 commit c60af16e1d6cc2237d58336546d6adfc067b6b8f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB37AJ CVE: CVE-2024-50215 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit d2f551b1f72b4c508ab9298419f6feadc3b5d791 ] ctrl->dh_key might be used across multiple calls to nvmet_setup_dhgroup() for the same controller. So it's better to nullify it after release on error path in order to avoid double free later in nvmet_destroy_auth(). Found by Linux Verification Center (linuxtesting.org) with Svace.
