[PATCH OLK-6.6] pinctrl: mcp23s08: Fix sleeping in atomic context due to regmap locking
by Pu Lehui 16 Jan '25

16 Jan '25

From: Evgenii Shatokhin <e.shatokhin(a)yadro.com> stable inclusion from stable-v6.6.70 commit 8c6fd5803b988a5e78c9b9e42c70a936d7cfc6ec category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBI4HE CVE: CVE-2024-57889 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit a37eecb705f33726f1fb7cd2a67e514a15dfe693 upstream. If a device uses MCP23xxx IO expander to receive IRQs, the following bug can happen: BUG: sleeping function called from invalid context at kernel/locking/mutex.c:283 in_atomic(): 1, irqs_disabled(): 1, non_block: 0, ... preempt_count: 1, expected: 0 ... Call Trace: ... __might_resched+0x104/0x10e __might_sleep+0x3e/0x62 mutex_lock+0x20/0x4c regmap_lock_mutex+0x10/0x18 regmap_update_bits_base+0x2c/0x66 mcp23s08_irq_set_type+0x1ae/0x1d6 __irq_set_trigger+0x56/0x172 __setup_irq+0x1e6/0x646 request_threaded_irq+0xb6/0x160 ... We observed the problem while experimenting with a touchscreen driver which used MCP23017 IO expander (I2C). The regmap in the pinctrl-mcp23s08 driver uses a mutex for protection from concurrent accesses, which is the default for regmaps without .fast_io, .disable_locking, etc. mcp23s08_irq_set_type() calls regmap_update_bits_base(), and the latter locks the mutex. However, __setup_irq() locks desc->lock spinlock before calling these functions. As a result, the system tries to lock the mutex whole holding the spinlock. It seems, the internal regmap locks are not needed in this driver at all. mcp->lock seems to protect the regmap from concurrent accesses already, except, probably, in mcp_pinconf_get/set. mcp23s08_irq_set_type() and mcp23s08_irq_mask/unmask() are called under chip_bus_lock(), which calls mcp23s08_irq_bus_lock(). The latter takes mcp->lock and enables regmap caching, so that the potentially slow I2C accesses are deferred until chip_bus_unlock(). The accesses to the regmap from mcp23s08_probe_one() do not need additional locking. In all remaining places where the regmap is accessed, except mcp_pinconf_get/set(), the driver already takes mcp->lock. This patch adds locking in mcp_pinconf_get/set() and disables internal locking in the regmap config. Among other things, it fixes the sleeping in atomic context described above.

[PATCH OLK-6.6] bpf: Check size for BTF-based ctx access of pointer members
by Tengda Wu 16 Jan '25

16 Jan '25

From: Kumar Kartikeya Dwivedi <memxor(a)gmail.com> stable inclusion from stable-v6.6.67 commit c7e1962a3807d2a9e8c192f23cd3a55794d08f90 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBHYOV Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 659b9ba7cb2d7adb64618b87ddfaa528a143766e upstream. Robert Morris reported the following program type which passes the verifier in [0]: SEC("struct_ops/bpf_cubic_init") void BPF_PROG(bpf_cubic_init, struct sock *sk) { asm volatile("r2 = *(u16*)(r1 + 0)"); // verifier should demand u64 asm volatile("*(u32 *)(r2 +1504) = 0"); // 1280 in some configs } The second line may or may not work, but the first instruction shouldn't pass, as it's a narrow load into the context structure of the struct ops callback. The code falls back to btf_ctx_access to ensure correctness and obtaining the types of pointers. Ensure that the size of the access is correctly checked to be 8 bytes, otherwise the verifier thinks the narrow load obtained a trusted BTF pointer and will permit loads/stores as it sees fit. Perform the check on size after we've verified that the load is for a pointer field, as for scalar values narrow loads are fine. Access to structs passed as arguments to a BPF program are also treated as scalars, therefore no adjustment is needed in their case. Existing verifier selftests are broken by this change, but because they were incorrect. Verifier tests for d_path were performing narrow load into context to obtain path pointer, had this program actually run it would cause a crash. The same holds for verifier_btf_ctx_access tests.

[PATCH OLK-5.10] fs/dirty_pages: Add exclusive open lock to prevent null pointer dereference
by Zizhi Wo 15 Jan '25

15 Jan '25

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBHTNK -------------------------------- The current mechanism for printing dirty pages involves "/proc/dirty/buffer_size" and "/proc/dirty/dirty_list" being able to be opened simultaneously. If "buffer_size" is opened firstly and 1 is written to it, and then "dirty_list" is opened, followed by writing 0 to "buffer_size". Then variable "buf_dirty" will be freed and set to NULL. However, the user can still access "buf_dirty" through the already opened "dirty_list", which could lead to a NULL pointer dereference issue. To prevent the NULL pointer dereference problem, add an exclusive open lock. And now "/proc/dirty/buffer_size" and "/proc/dirty/dirty_list" cannot be opened at the same time unless "/proc/dirty/buffer_size" is opened in read-only mode. At the same time, "buff_used" and "buff_lock" in the original code are not needed, and the redundant code is deleted.

[PATCH openEuler-1.0-LTS] ALSA: usb-audio: Fix out of bounds reads when finding clock sources
by Luo Gengkun 14 Jan '25

14 Jan '25

From: Takashi Iwai <tiwai(a)suse.de> stable inclusion from stable-v5.10.231 commit 45a92cbc88e4013bfed7fd2ccab3ade45f8e896b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBDHGG CVE: CVE-2024-53150 Reference: https://git.kernel.org/stable/c/45a92cbc88e4013bfed7fd2ccab3ade45f8e896b -------------------------------- commit a3dd4d63eeb452cfb064a13862fb376ab108f6a6 upstream. The current USB-audio driver code doesn't check bLength of each descriptor at traversing for clock descriptors. That is, when a device provides a bogus descriptor with a shorter bLength, the driver might hit out-of-bounds reads. For addressing it, this patch adds sanity checks to the validator functions for the clock descriptor traversal. When the descriptor length is shorter than expected, it's skipped in the loop. For the clock source and clock multiplier descriptors, we can just check bLength against the sizeof() of each descriptor type. OTOH, the clock selector descriptor of UAC2 and UAC3 has an array of bNrInPins elements and two more fields at its tail, hence those have to be checked in addition to the sizeof() check.

[PATCH OLK-5.10] sched: psi: fix bogus pressure spikes from aggregation race
by Chen Ridong 14 Jan '25

14 Jan '25

From: Johannes Weiner <hannes(a)cmpxchg.org> stable inclusion from stable-v6.6.55 commit 1f997b1d13e0b9819468e577622e747b546516fe category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB6YDK Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 3840cbe24cf060ea05a585ca497814609f5d47d1 ] Brandon reports sporadic, non-sensical spikes in cumulative pressure time (total=) when reading cpu.pressure at a high rate. This is due to a race condition between reader aggregation and tasks changing states. While it affects all states and all resources captured by PSI, in practice it most likely triggers with CPU pressure, since scheduling events are so frequent compared to other resource events. The race context is the live snooping of ongoing stalls during a pressure read. The read aggregates per-cpu records for stalls that have concluded, but will also incorporate ad-hoc the duration of any active state that hasn't been recorded yet. This is important to get timely measurements of ongoing stalls. Those ad-hoc samples are calculated on-the-fly up to the current time on that CPU; since the stall hasn't concluded, it's expected that this is the minimum amount of stall time that will enter the per-cpu records once it does. The problem is that the path that concludes the state uses a CPU clock read that is not synchronized against aggregators; the clock is read outside of the seqlock protection. This allows aggregators to race and snoop a stall with a longer duration than will actually be recorded. With the recorded stall time being less than the last snapshot remembered by the aggregator, a subsequent sample will underflow and observe a bogus delta value, resulting in an erratic jump in pressure.

[PATCH OLK-6.6] sched: psi: fix bogus pressure spikes from aggregation race
by Chen Ridong 14 Jan '25

14 Jan '25

From: Johannes Weiner <hannes(a)cmpxchg.org> stable inclusion from stable-v6.6.55 commit 1f997b1d13e0b9819468e577622e747b546516fe category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB6YDK Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 3840cbe24cf060ea05a585ca497814609f5d47d1 ] Brandon reports sporadic, non-sensical spikes in cumulative pressure time (total=) when reading cpu.pressure at a high rate. This is due to a race condition between reader aggregation and tasks changing states. While it affects all states and all resources captured by PSI, in practice it most likely triggers with CPU pressure, since scheduling events are so frequent compared to other resource events. The race context is the live snooping of ongoing stalls during a pressure read. The read aggregates per-cpu records for stalls that have concluded, but will also incorporate ad-hoc the duration of any active state that hasn't been recorded yet. This is important to get timely measurements of ongoing stalls. Those ad-hoc samples are calculated on-the-fly up to the current time on that CPU; since the stall hasn't concluded, it's expected that this is the minimum amount of stall time that will enter the per-cpu records once it does. The problem is that the path that concludes the state uses a CPU clock read that is not synchronized against aggregators; the clock is read outside of the seqlock protection. This allows aggregators to race and snoop a stall with a longer duration than will actually be recorded. With the recorded stall time being less than the last snapshot remembered by the aggregator, a subsequent sample will underflow and observe a bogus delta value, resulting in an erratic jump in pressure. Fix this by moving the clock read of the state change into the seqlock protection. This ensures no aggregation can snoop live stalls past the time that's recorded when the state concludes.

[PATCH OLK-5.10] [Backport] btrfs: check folio mapping after unlock in relocate_one_folio()
by Yongjian Sun 13 Jan '25

13 Jan '25

mainline inclusion from mainline-v6.12-rc3 commit 3e74859ee35edc33a022c3f3971df066ea0ca6b9 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBG2PL CVE: CVE-2024-56758 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- When we call btrfs_read_folio() to bring a folio uptodate, we unlock the folio. The result of that is that a different thread can modify the mapping (like remove it with invalidate) before we call folio_lock(). This results in an invalid page and we need to try again. In particular, if we are relocating concurrently with aborting a transaction, this can result in a crash like the following: BUG: kernel NULL pointer dereference, address: 0000000000000000 PGD 0 P4D 0 Oops: 0000 [#1] SMP CPU: 76 PID: 1411631 Comm: kworker/u322:5 Workqueue: events_unbound btrfs_reclaim_bgs_work RIP: 0010:set_page_extent_mapped+0x20/0xb0 RSP: 0018:ffffc900516a7be8 EFLAGS: 00010246 RAX: ffffea009e851d08 RBX: ffffea009e0b1880 RCX: 0000000000000000 RDX: 0000000000000000 RSI: ffffc900516a7b90 RDI: ffffea009e0b1880 RBP: 0000000003573000 R08: 0000000000000001 R09: ffff88c07fd2f3f0 R10: 0000000000000000 R11: 0000194754b575be R12: 0000000003572000 R13: 0000000003572fff R14: 0000000000100cca R15: 0000000005582fff FS: 0000000000000000(0000) GS:ffff88c07fd00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000000 CR3: 000000407d00f002 CR4: 00000000007706f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 PKRU: 55555554 Call Trace: <TASK> ? __die+0x78/0xc0 ? page_fault_oops+0x2a8/0x3a0 ? __switch_to+0x133/0x530 ? wq_worker_running+0xa/0x40 ? exc_page_fault+0x63/0x130 ? asm_exc_page_fault+0x22/0x30 ? set_page_extent_mapped+0x20/0xb0 relocate_file_extent_cluster+0x1a7/0x940 relocate_data_extent+0xaf/0x120 relocate_block_group+0x20f/0x480 btrfs_relocate_block_group+0x152/0x320 btrfs_relocate_chunk+0x3d/0x120 btrfs_reclaim_bgs_work+0x2ae/0x4e0 process_scheduled_works+0x184/0x370 worker_thread+0xc6/0x3e0 ? blk_add_timer+0xb0/0xb0 kthread+0xae/0xe0 ? flush_tlb_kernel_range+0x90/0x90 ret_from_fork+0x2f/0x40 ? flush_tlb_kernel_range+0x90/0x90 ret_from_fork_asm+0x11/0x20 </TASK> This occurs because cleanup_one_transaction() calls destroy_delalloc_inodes() which calls invalidate_inode_pages2() which takes the folio_lock before setting mapping to NULL. We fail to check this, and subsequently call set_extent_mapping(), which assumes that mapping != NULL (in fact it asserts that in debug mode) Note that the "fixes" patch here is not the one that introduced the race (the very first iteration of this code from 2009) but a more recent change that made this particular crash happen in practice.

From: Ryusuke Konishi <konishi.ryusuke(a)gmail.com> stable inclusion from stable-v5.10.231 commit b017697a517f8779ada4e8ce1c2c75dbf60a2636 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB5KQZ Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit cd45e963e44b0f10d90b9e6c0e8b4f47f3c92471 upstream. Patch series "nilfs2: fix null-ptr-deref bugs on block tracepoints". This series fixes null pointer dereference bugs that occur when using nilfs2 and two block-related tracepoints. This patch (of 2): It has been reported that when using "block:block_touch_buffer" tracepoint, touch_buffer() called from __nilfs_get_folio_block() causes a NULL pointer dereference, or a general protection fault when KASAN is enabled. This happens because since the tracepoint was added in touch_buffer(), it references the dev_t member bh->b_bdev->bd_dev regardless of whether the buffer head has a pointer to a block_device structure. In the current implementation, the block_device structure is set after the function returns to the caller. Here, touch_buffer() is used to mark the folio/page that owns the buffer head as accessed, but the common search helper for folio/page used by the caller function was optimized to mark the folio/page as accessed when it was reimplemented a long time ago, eliminating the need to call touch_buffer() here in the first place. So this solves the issue by eliminating the touch_buffer() call itself.

[PATCH OLK-6.6] bpf: put bpf_link's program when link is safe to be deallocated
by Tengda Wu 13 Jan '25

13 Jan '25

From: Andrii Nakryiko <andrii(a)kernel.org> stable inclusion from stable-v6.6.66 commit 5fe23c57abadfd46a7a66e81f3536e4757252a0b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBHAY1 CVE: CVE-2024-56786 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit f44ec8733a8469143fde1984b5e6931b2e2f6f3f ] In general, BPF link's underlying BPF program should be considered to be reachable through attach hook -> link -> prog chain, and, pessimistically, we have to assume that as long as link's memory is not safe to free, attach hook's code might hold a pointer to BPF program and use it. As such, it's not (generally) correct to put link's program early before waiting for RCU GPs to go through. More eager bpf_prog_put() that we currently do is mostly correct due to BPF program's release code doing similar RCU GP waiting, but as will be shown in the following patches, BPF program can be non-sleepable (and, thus, reliant on only "classic" RCU GP), while BPF link's attach hook can have sleepable semantics and needs to be protected by RCU Tasks Trace, and for such cases BPF link has to go through RCU Tasks Trace + "classic" RCU GPs before being deallocated. And so, if we put BPF program early, we might free BPF program before we free BPF link, leading to use-after-free situation. So, this patch defers bpf_prog_put() until we are ready to perform bpf_link's deallocation. At worst, this delays BPF program freeing by one extra RCU GP, but that seems completely acceptable. Alternatively, we'd need more elaborate ways to determine BPF hook, BPF link, and BPF program lifetimes, and how they relate to each other, which seems like an unnecessary complication. Note, for most BPF links we still will perform eager bpf_prog_put() and link dealloc, so for those BPF links there are no observable changes whatsoever. Only BPF links that use deferred dealloc might notice slightly delayed freeing of BPF programs. Also, to reduce code and logic duplication, extract program put + link dealloc logic into bpf_link_dealloc() helper.

The buf (dma cookie) and len stored in this structure are passed to dma_unmap_single() by stmmac_tx_clean(). The DMA API requires that the dma cookie passed to dma_unmap_single() is the same as the value returned from dma_map_single(). However, by moving the assignment later, this is not the case when priv->dma_cap.addr64 > 32 as "des" is offset by proto_hdr_len. This causes problems such as: dwc-eth-dwmac 2490000.ethernet eth0: Tx DMA map failed and with DMA_API_DEBUG enabled: DMA-API: dwc-eth-dwmac 2490000.ethernet: device driver tries to +free DMA memory it has not allocated [device address=0x000000ffffcf65c0] [size=66 bytes] Fix this by maintaining "des" as the original DMA cookie, and use tso_des to pass the offset DMA cookie to stmmac_tso_allocator().
