[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

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. For reproduction, the following diff manually overlays 'i_lru' with 'rcu' as, otherwise, one would require some good portion of luck for gambling an unlucky RANDSTRUCT seed: --- a/include/linux/fs.h +++ b/include/linux/fs.h @@ -629,6 +629,7 @@ struct inode { umode_t i_mode; unsigned short i_opflags; kuid_t i_uid; + struct list_head i_lru; /* inode LRU list */ kgid_t i_gid; unsigned int i_flags; @@ -690,7 +691,6 @@ struct inode { u16 i_wb_frn_avg_time; u16 i_wb_frn_history; #endif - struct list_head i_lru; /* inode LRU list */ struct list_head i_sb_list; struct list_head i_wb_list; /* backing dev writeback list */ union { The tracefs inode does not need to supply its own RCU delayed destruction of its inode.

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 OLK-6.6] iommu: Restore lost return in iommu_report_device_fault()

From: Barak Biber <bbiber(a)nvidia.com> stable inclusion from stable-v6.10.7 commit cc6bc2ab1663ec9353636416af22452b078510e9 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAOXZS CVE: CVE-2024-44994 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit fca5b78511e98bdff2cdd55c172b23200a7b3404 ] When iommu_report_device_fault gets called with a partial fault it is supposed to collect the fault into the group and then return. Instead the return was accidently deleted which results in trying to process the fault and an eventual crash. Deleting the return was a typo, put it back.

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/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).
