[PATCH OLK-5.10] sched: sch_cake: add bounds checks to host bulk flow fairness counts
by Dong Chenchen 15 Feb '25

15 Feb '25

From: Toke Høiland-Jørgensen <toke(a)redhat.com> mainline inclusion from mainline-v6.13-rc7 commit 737d4d91d35b5f7fa5bb442651472277318b0bfd category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBIQOT CVE: CVE-2025-21647 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Even though we fixed a logic error in the commit cited below, syzbot still managed to trigger an underflow of the per-host bulk flow counters, leading to an out of bounds memory access. To avoid any such logic errors causing out of bounds memory accesses, this commit factors out all accesses to the per-host bulk flow counters to a series of helpers that perform bounds-checking before any increments and decrements. This also has the benefit of improving readability by moving the conditional checks for the flow mode into these helpers, instead of having them spread out throughout the code (which was the cause of the original logic error). As part of this change, the flow quantum calculation is consolidated into a helper function, which means that the dithering applied to the ost load scaling is now applied both in the DRR rotation and when a sparse flow's quantum is first initiated. The only user-visible effect of this is that the maximum packet size that can be sent while a flow stays sparse will now vary with +/- one byte in some cases. This should not make a noticeable difference in practice, and thus it's not worth complicating the code to preserve the old behaviour.

This assumption is bogus since it's valid to create egress qdiscs with major handle ffff: Budimir Markovic found that for qdiscs like DRR that maintain an active class list, it will cause a UAF with a dangling class pointer. In 066a3b5b2346, the concern was to avoid iterating over the ingress qdisc since its parent is itself. The proper fix is to stop when parent TC_H_ROOT is reached because the only way to retrieve ingress is when a hierarchy which does not contain a ffff: major handle call into qdisc_lookup with TC_H_MAJ(TC_H_ROOT). In the scenario where major ffff: is an egress qdisc in any of the tree levels, the updates will also propagate to TC_H_ROOT, which then the iteration must stop.

[PATCH OLK-6.6] mm/vmalloc: combine all TLB flush operations of KASAN shadow virtual address into one operation

15 Feb '25

From: Adrian Huang <ahuang12(a)lenovo.com> mainline inclusion from mainline-v6.13-rc1 commit 9e9e085effe9b7e342138fde3cf8577d22509932 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAMT CVE: CVE-2024-56559 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ------------------------------------------- When compiling kernel source 'make -j $(nproc)' with the up-and-running KASAN-enabled kernel on a 256-core machine, the following soft lockup is shown: watchdog: BUG: soft lockup - CPU#28 stuck for 22s!

The following ftrace log shows that the lockup CPU spends too much time iterating vmap_nodes and flushing TLB when purging vm_area structures. (Some info is trimmed). kworker: funcgraph_entry: | drain_vmap_area_work() { kworker: funcgraph_entry: | mutex_lock() { kworker: funcgraph_entry: 1.092 us | __cond_resched(); kworker: funcgraph_exit: 3.306 us | } ... ... kworker: funcgraph_entry: | flush_tlb_kernel_range() { ... ... kworker: funcgraph_exit: # 7533.649 us | } ... ... kworker: funcgraph_entry: 2.344 us | mutex_unlock(); kworker: funcgraph_exit: $ 23871554 us | } The drain_vmap_area_work() spends over 23 seconds. There are 2805 flush_tlb_kernel_range() calls in the ftrace log. * One is called in __purge_vmap_area_lazy(). * Others are called by purge_vmap_node->kasan_release_vmalloc. purge_vmap_node() iteratively releases kasan vmalloc allocations and flushes TLB for each vmap_area. - [Rough calculation] Each flush_tlb_kernel_range() runs about 7.5ms. -- 2804 * 7.5ms = 21.03 seconds. -- That's why a soft lock is triggered. 2. Extending the soft lockup time can work around the issue (For example, # echo 60 > /proc/sys/kernel/watchdog_thresh). This confirms the above-mentioned speculation: drain_vmap_area_work() spends too much time. If we combine all TLB flush operations of the KASAN shadow virtual address into one operation in the call path 'purge_vmap_node()->kasan_release_vmalloc()', the running time of drain_vmap_area_work() can be saved greatly. The idea is from the flush_tlb_kernel_range() call in __purge_vmap_area_lazy(). And, the soft lockup won't be triggered. Here is the test result based on 6.10: [6.10 wo/ the patch] 1. ftrace latency profiling (record a trace if the latency > 20s). echo 20000000 > /sys/kernel/debug/tracing/tracing_thresh echo drain_vmap_area_work > /sys/kernel/debug/tracing/set_graph_function echo function_graph > /sys/kernel/debug/tracing/current_tracer echo 1 > /sys/kernel/debug/tracing/tracing_on 2. Run `make -j $(nproc)` to compile the kernel source 3. Once the soft lockup is reproduced, check the ftrace log: cat /sys/kernel/debug/tracing/trace # tracer: function_graph # # CPU DURATION FUNCTION CALLS # | | | | | | | 76) $ 50412985 us | } /* __purge_vmap_area_lazy */ 76) $ 50412997 us | } /* drain_vmap_area_work */ 76) $ 29165911 us | } /* __purge_vmap_area_lazy */ 76) $ 29165926 us | } /* drain_vmap_area_work */ 91) $ 53629423 us | } /* __purge_vmap_area_lazy */ 91) $ 53629434 us | } /* drain_vmap_area_work */ 91) $ 28121014 us | } /* __purge_vmap_area_lazy */ 91) $ 28121026 us | } /* drain_vmap_area_work */ [6.10 w/ the patch] 1. Repeat step 1-2 in "[6.10 wo/ the patch]" 2. The soft lockup is not triggered and ftrace log is empty. cat /sys/kernel/debug/tracing/trace # tracer: function_graph # # CPU DURATION FUNCTION CALLS # | | | | | | | 3. Setting 'tracing_thresh' to 10/5 seconds does not get any ftrace log. 4. Setting 'tracing_thresh' to 1 second gets ftrace log. cat /sys/kernel/debug/tracing/trace # tracer: function_graph # # CPU DURATION FUNCTION CALLS # | | | | | | | 23) $ 1074942 us | } /* __purge_vmap_area_lazy */ 23) $ 1074950 us | } /* drain_vmap_area_work */ The worst execution time of drain_vmap_area_work() is about 1 second.

[PATCH OLK-6.6] fs/proc: fix softlockup in __read_vmcore (part 2)
by Li Huafei 13 Feb '25

13 Feb '25

From: Rik van Riel <riel(a)surriel.com> stable inclusion from stable-v6.6.74 commit a5a2ee8144c3897d37403a69118c3e3dc5713958 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBLWTG CVE: CVE-2025-21694 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit cbc5dde0a461240046e8a41c43d7c3b76d5db952 upstream. Since commit 5cbcb62dddf5 ("fs/proc: fix softlockup in __read_vmcore") the number of softlockups in __read_vmcore at kdump time have gone down, but they still happen sometimes. In a memory constrained environment like the kdump image, a softlockup is not just a harmless message, but it can interfere with things like RCU freeing memory, causing the crashdump to get stuck. The second loop in __read_vmcore has a lot more opportunities for natural sleep points, like scheduling out while waiting for a data write to happen, but apparently that is not always enough. Add a cond_resched() to the second loop in __read_vmcore to (hopefully) get rid of the softlockups. Link: https://lkml.kernel.org/r/20250110102821.2a37581b@fangorn Fixes: 5cbcb62dddf5 ("fs/proc: fix softlockup in __read_vmcore") Signed-off-by: Rik van Riel <riel(a)surriel.com> Reported-by: Breno Leitao <leitao(a)debian.org> Cc: Baoquan He <bhe(a)redhat.com> Cc: Dave Young <dyoung(a)redhat.com> Cc: Vivek Goyal <vgoyal(a)redhat.com> Cc: <stable(a)vger.kernel.org> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Signed-off-by: Li Huafei <lihuafei1(a)huawei.com> --- fs/proc/vmcore.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/fs/proc/vmcore.c b/fs/proc/vmcore.c index 8319bcbe3ee3..3303cb04e12c 100644 --- a/fs/proc/vmcore.c +++ b/fs/proc/vmcore.c @@ -404,6 +404,8 @@ static ssize_t __read_vmcore(struct iov_iter *iter, loff_t *fpos) if (!iov_iter_count(iter)) return acc; } + + cond_resched(); } return acc; -- 2.25.1

[PATCH OLK-6.6] irqchip/gic-v3-its: Don't enable interrupts in its_irq_set_vcpu_affinity()
by Yuntao Liu 12 Feb '25

12 Feb '25

From: Tomas Krcka <krckatom(a)amazon.de> stable inclusion from stable-v6.6.74 commit 6c84ff2e788fce0099ee3e71a3ed258b1ca1a223 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBL2TI CVE: CVE-2024-57949 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 35cb2c6ce7da545f3b5cb1e6473ad7c3a6f08310 upstream. The following call-chain leads to enabling interrupts in a nested interrupt disabled section: irq_set_vcpu_affinity() irq_get_desc_lock() raw_spin_lock_irqsave() <--- Disable interrupts its_irq_set_vcpu_affinity() guard(raw_spinlock_irq) <--- Enables interrupts when leaving the guard() irq_put_desc_unlock() <--- Warns because interrupts are enabled This was broken in commit b97e8a2f7130, which replaced the original raw_spin_[un]lock() pair with guard(raw_spinlock_irq). Fix the issue by using guard(raw_spinlock).

[PATCH OLK-6.6] ALSA: caiaq: Use snd_card_free_when_closed() at disconnection
by Yu Kuai 11 Feb '25

11 Feb '25

From: Takashi Iwai <tiwai(a)suse.de> stable inclusion from stable-v6.6.64 commit 4507a8b9b30344c5ddd8219945f446d47e966a6d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAFS CVE: CVE-2024-56531 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit b04dcbb7f7b1908806b7dc22671cdbe78ff2b82c ] The USB disconnect callback is supposed to be short and not too-long waiting. OTOH, the current code uses snd_card_free() at disconnection, but this waits for the close of all used fds, hence it can take long. It eventually blocks the upper layer USB ioctls, which may trigger a soft lockup. An easy workaround is to replace snd_card_free() with snd_card_free_when_closed(). This variant returns immediately while the release of resources is done asynchronously by the card device release at the last close. This patch also splits the code to the disconnect and the free phases; the former is called immediately at the USB disconnect callback while the latter is called from the card destructor.
