[PATCH OLK-5.10] x86/mm: Do not shuffle CPU entry areas without KASLR
by Kaixiong Yu 14 Sep '24

14 Sep '24

From: Michal Koutný <mkoutny(a)suse.com> mainline inclusion from mainline-v6.3-rc4 commit a3f547addcaa10df5a226526bc9e2d9a94542344 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IARGQX CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- The commit 97e3d26b5e5f ("x86/mm: Randomize per-cpu entry area") fixed an omission of KASLR on CPU entry areas. It doesn't take into account KASLR switches though, which may result in unintended non-determinism when a user wants to avoid it (e.g. debugging, benchmarking). Generate only a single combination of CPU entry areas offsets -- the linear array that existed prior randomization when KASLR is turned off. Since we have 3f148f331814 ("x86/kasan: Map shadow for percpu pages on demand") and followups, we can use the more relaxed guard kasrl_enabled() (in contrast to kaslr_memory_enabled()).

[PATCH OLK-6.6 v2] tracefs: Use generic inode RCU for synchronizing freeing
by Long Li 14 Sep '24

14 Sep '24

From: Steven Rostedt <rostedt(a)goodmis.org> stable inclusion from stable-v6.6.45 commit 726f4c241e17be75a9cf6870d80cd7479dc89e8f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAOXYV CVE: CVE-2024-44959 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… -------------------------------- commit 0b6743bd60a56a701070b89fb80c327a44b7b3e2 upstream. With structure layout randomization enabled for 'struct inode' we need to avoid overlapping any of the RCU-used / initialized-only-once members, e.g. i_lru or i_sb_list to not corrupt related list traversals when making use of the rcu_head. For an unlucky structure layout of 'struct inode' we may end up with the following splat when running the ftrace selftests: [<...>] list_del corruption, ffff888103ee2cb0->next (tracefs_inode_cache+0x0/0x4e0 [slab object]) is NULL (prev is tracefs_inode_cache+0x78/0x4e0 [slab object]) [<...>] ------------[ cut here ]------------ [<...>] kernel BUG at lib/list_debug.c:54!

Dumping the layout of the relevant parts of 'struct tracefs_inode' gives the following: struct tracefs_inode { union { struct inode { struct list_head { struct list_head * next; /* 0 8 */ struct list_head * prev; /* 8 8 */ } i_lru; [...] } vfs_inode; struct callback_head { void (*func)(struct callback_head *); /* 0 8 */ struct callback_head * next; /* 8 8 */ } rcu; }; [...] }; Above shows that 'vfs_inode.i_lru' overlaps with 'rcu' which will destroy the 'i_lru' list as soon as the 'rcu' member gets used, e.g. in call_rcu() or later when calling the RCU callback. This will disturb concurrent list traversals as well as object reuse which assumes these list heads will keep their integrity.

The tracefs code can unlink the inode from its list in the destroy_inode() callback, and the simply free it from the free_inode() callback. This should provide the same protection.

[PATCH openEuler-1.0-LTS] xhci: Fix Panther point NULL pointer deref at full-speed re-enumeration
by Peng Zhang 14 Sep '24

From: Mathias Nyman <mathias.nyman(a)linux.intel.com> stable inclusion from stable-v4.19.321 commit ef0a0e616b2789bb804a0ce5e161db03170a85b6 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAOXZE CVE: CVE-2024-45006 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit af8e119f52e9c13e556be9e03f27957554a84656 upstream. re-enumerating full-speed devices after a failed address device command can trigger a NULL pointer dereference. Full-speed devices may need to reconfigure the endpoint 0 Max Packet Size value during enumeration. Usb core calls usb_ep0_reinit() in this case, which ends up calling xhci_configure_endpoint(). On Panther point xHC the xhci_configure_endpoint() function will additionally check and reserve bandwidth in software. Other hosts do this in hardware If xHC address device command fails then a new xhci_virt_device structure is allocated as part of re-enabling the slot, but the bandwidth table pointers are not set up properly here. This triggers the NULL pointer dereference the next time usb_ep0_reinit() is called and xhci_configure_endpoint() tries to check and reserve bandwidth [46710.713538] usb 3-1: new full-speed USB device number 5 using xhci_hcd [46710.713699] usb 3-1: Device not responding to setup address.

From: Yonghong Song <yonghong.song(a)linux.dev> stable inclusion from stable-v6.6.48 commit 7cad3174cc79519bf5f6c4441780264416822c08 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAQOJD CVE: CVE-2024-45020 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit bed2eb964c70b780fb55925892a74f26cb590b25 upstream. Daniel Hodges reported a kernel verifier crash when playing with sched-ext. Further investigation shows that the crash is due to invalid memory access in stacksafe(). More specifically, it is the following code: if (exact != NOT_EXACT && old->stack[spi].slot_type[i % BPF_REG_SIZE] != cur->stack[spi].slot_type[i % BPF_REG_SIZE]) return false; The 'i' iterates old->allocated_stack. If cur->allocated_stack < old->allocated_stack the out-of-bound access will happen. To fix the issue add 'i >= cur->allocated_stack' check such that if the condition is true, stacksafe() should fail. Otherwise, cur->stack[spi].slot_type[i % BPF_REG_SIZE] memory access is legal.

[PATCH OLK-5.10] mm: fix failure to unmap pte on highmem systems
by Wupeng Ma 14 Sep '24

14 Sep '24

From: Ryan Roberts <ryan.roberts(a)arm.com> mainline inclusion from mainline-v6.5-rc1 commit 3b65f437d9e8dd696a2b88e7afcd51385532ab35 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAQT9Q Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The loser of a race to service a pte for a device private entry in the swap path previously unlocked the ptl, but failed to unmap the pte. This only affects highmem systems since unmapping a pte is a noop on non-highmem systems.

[PATCH OLK-5.10] mm/hugetlb: fix pgtable lock on pmd sharing
by Wupeng Ma 14 Sep '24

14 Sep '24

From: Peter Xu <peterx(a)redhat.com> mainline inclusion from mainline-v6.5-rc1 commit 349d1670008d3dab99a11b015bef51ad3f26fb4f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAQT9Q Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Huge pmd sharing operates on PUD not PMD, huge_pte_lock() is not suitable in this case because it should only work for last level pte changes, while pmd sharing is always one level higher. Meanwhile, here we're locking over the spte pgtable lock which is even not a lock for current mm but someone else's. It seems even racy on operating on the lock, as after put_page() of the spte pgtable page logically the page can be released, so at least the spin_unlock() needs to be done after the put_page(). No report I am aware, I'm not even sure whether it'll just work on taking the spte pmd lock, because while we're holding i_mmap read lock it probably means the vma interval tree is frozen, all pte allocators over this pud entry could always find the specific svma and spte page, so maybe they'll serialize on this spte page lock? Even so, doesn't seem to be expected. It just seems to be an accident of cb900f412154. Fix it with the proper pud lock (which is the mm's page_table_lock).

[PATCH v2 OLK-6.6] KVM:arm64:Add a kvm module param to get current enabled GIC version

From: Yanan Wang <wangyanan55(a)huawei.com> virt inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IAR5EZ CVE: NA Using GICv4.1 is not a 100% win in all scenarios, sometimes we need to use different GIC version in different usecases. Given that there is not a straight forward way to check the GIC version that system is using (e.g., kernel messages may be overided with time elapses), let's add a module param in KVM such that userspace can check the GIC version simply by reading /sys/module/kvm/parameters/gic_version.

[PATCH v2 OLK-6.6] KVM:arm64:Add a kvm module param to get current enabled GIC version
by Zhiqiang Ni 13 Sep '24

13 Sep '24

From: Yanan Wang <wangyanan55(a)huawei.com> virt inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IAR5EZ CVE: NA Using GICv4.1 is not a 100% win in all scenarios, sometimes we need to use different GIC version in different usecases. Given that there is not a straight forward way to check the GIC version that system is using (e.g., kernel messages may be overided with time elapses), let's add a module param in KVM such that userspace can check the GIC version simply by reading /sys/module/kvm/parameters/gic_version.
