From: Leo Yan <leo.yan(a)arm.com> stable inclusion from stable-v6.6.59 commit a14a075a14af8d622c576145455702591bdde09d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB2BWY CVE: CVE-2024-50131 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 0b6e2e22cb23105fcb171ab92f0f7516c69c8471 ] strlen() returns a string length excluding the null byte. If the string length equals to the maximum buffer length, the buffer will have no space for the NULL terminating character. This commit checks this condition and returns failure for it.

[PATCH openEuler-1.0-LTS] fs: call fsnotify_sb_delete after evict_inodes
by Zizhi Wo 11 Nov '24

11 Nov '24

From: Eric Sandeen <sandeen(a)redhat.com> mainline inclusion from mainline-v5.5-rc3 commit 1edc8eb2e93130e36ac74ac9c80913815a57d413 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB3D4A CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- When a filesystem is unmounted, we currently call fsnotify_sb_delete() before evict_inodes(), which means that fsnotify_unmount_inodes() must iterate over all inodes on the superblock looking for any inodes with watches. This is inefficient and can lead to livelocks as it iterates over many unwatched inodes. At this point, SB_ACTIVE is gone and dropping refcount to zero kicks the inode out out immediately, so anything processed by fsnotify_sb_delete / fsnotify_unmount_inodes gets evicted in that loop. After that, the call to evict_inodes will evict everything else with a zero refcount. This should speed things up overall, and avoid livelocks in fsnotify_unmount_inodes().

[PATCH OLK-6.6] drm/amd/display: Check null pointers before multiple uses
by Gu Bowen 11 Nov '24

11 Nov '24

From: Alex Hung <alex.hung(a)amd.com> mainline inclusion from mainline-v6.12-rc1 commit fdd5ecbbff751c3b9061d8ebb08e5c96119915b4 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYR8O CVE: CVE-2024-49920 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- [WHAT & HOW] Poniters, such as stream_enc and dc->bw_vbios, are null checked previously in the same function, so Coverity warns "implies that stream_enc and dc->bw_vbios might be null". They are used multiple times in the subsequent code and need to be checked. This fixes 10 FORWARD_NULL issues reported by Coverity.

[PATCH OLK-6.6 V1] drm/amd/display: Add null check for pipe_ctx->plane_state in dcn20_program_pipe
by Zicheng Qu 09 Nov '24

09 Nov '24

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.

[PATCH openEuler-1.0-LTS] serial: core: Fix atomicity violation in uart_tiocmget
by Yi Yang 08 Nov '24

08 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 OLK-6.6] blk-rq-qos: fix crash on rq_qos_wait vs. rq_qos_wake_function race

So rq_qos_wake_function() calls wake_up_process(data->task), which calls try_to_wake_up(), which faults in raw_spin_lock_irqsave(&p->pi_lock). p comes from data->task, and data comes from the waitqueue entry, which is stored on the waiter's stack in rq_qos_wait(). Analyzing the core dump with drgn, I found that the waiter had already woken up and moved on to a completely unrelated code path, clobbering what was previously data->task. Meanwhile, the waker was passing the clobbered garbage in data->task to wake_up_process(), leading to the crash. What's happening is that in between rq_qos_wake_function() deleting the waitqueue entry and calling wake_up_process(), rq_qos_wait() is finding that it already got a token and returning. The race looks like this: rq_qos_wait() rq_qos_wake_function() ============================================================== prepare_to_wait_exclusive() data->got_token = true; list_del_init(&curr->entry); if (data.got_token) break; finish_wait(&rqw->wait, &data.wq); ^- returns immediately because list_empty_careful(&wq_entry->entry) is true ... return, go do something else ... wake_up_process(data->task) (NO LONGER VALID!)-^ Normally, finish_wait() is supposed to synchronize against the waker. But, as noted above, it is returning immediately because the waitqueue entry has already been removed from the waitqueue. The bug is that rq_qos_wake_function() is accessing the waitqueue entry AFTER deleting it. Note that autoremove_wake_function() wakes the waiter and THEN deletes the waitqueue entry, which is the proper order. Fix it by swapping the order. We also need to use list_del_init_careful() to match the list_empty_careful() in finish_wait().

[PATCH OLK-6.6] [Backport] smb: client: Handle kstrdup failures for passwords
by Yongjian Sun 07 Nov '24

07 Nov '24

From: Henrique Carvalho <henrique.carvalho(a)suse.com> mainline inclusion from mainline-v6.12-rc3 commit 9a5dd61151399ad5a5d69aad28ab164734c1e3bc category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB2BX3 CVE: CVE-2024-50120 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- In smb3_reconfigure(), after duplicating ctx->password and ctx->password2 with kstrdup(), we need to check for allocation failures. If ses->password allocation fails, return -ENOMEM. If ses->password2 allocation fails, free ses->password, set it to NULL, and return -ENOMEM.

[PATCH OLK-6.6] drm/amd/display: Check null pointers before multiple uses
by Gu Bowen 07 Nov '24

07 Nov '24

From: Alex Hung <alex.hung(a)amd.com> mainline inclusion from mainline-v6.12-rc1 commit fdd5ecbbff751c3b9061d8ebb08e5c96119915b4 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYR8O CVE: CVE-2024-49920 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- [WHAT & HOW] Poniters, such as stream_enc and dc->bw_vbios, are null checked previously in the same function, so Coverity warns "implies that stream_enc and dc->bw_vbios might be null". They are used multiple times in the subsequent code and need to be checked. This fixes 10 FORWARD_NULL issues reported by Coverity.

If the `nfsd_client_shrinker` is running concurrently, the `expire_client` function will first unhash this client and then destroy it. This can lead to the following warning. Additionally, numerous use-after-free errors may occur as well. nfsd_client_shrinker echo 0 > /proc/fs/nfsd/threads expire_client nfsd_shutdown_net unhash_client ... nfs4_state_shutdown_net /* won't wait shrinker exit */ /* cancel_work(&nn->nfsd_shrinker_work) * nfsd_file for this /* won't destroy unhashed client1 */ * client1 still alive nfs4_state_destroy_net */ nfsd_file_cache_shutdown /* trigger warning */ kmem_cache_destroy(nfsd_file_slab) kmem_cache_destroy(nfsd_file_mark_slab) /* release nfsd_file and mark */ __destroy_client ==================================================================== BUG nfsd_file (Not tainted): Objects remaining in nfsd_file on __kmem_cache_shutdown() -------------------------------------------------------------------- CPU: 4 UID: 0 PID: 764 Comm: sh Not tainted 6.12.0-rc3+ #1 dump_stack_lvl+0x53/0x70 slab_err+0xb0/0xf0 __kmem_cache_shutdown+0x15c/0x310 kmem_cache_destroy+0x66/0x160 nfsd_file_cache_shutdown+0xac/0x210 [nfsd] nfsd_destroy_serv+0x251/0x2a0 [nfsd] nfsd_svc+0x125/0x1e0 [nfsd] write_threads+0x16a/0x2a0 [nfsd] nfsctl_transaction_write+0x74/0xa0 [nfsd] vfs_write+0x1a5/0x6d0 ksys_write+0xc1/0x160 do_syscall_64+0x5f/0x170 entry_SYSCALL_64_after_hwframe+0x76/0x7e ==================================================================== BUG nfsd_file_mark (Tainted: G B W ): Objects remaining nfsd_file_mark on __kmem_cache_shutdown() -------------------------------------------------------------------- dump_stack_lvl+0x53/0x70 slab_err+0xb0/0xf0 __kmem_cache_shutdown+0x15c/0x310 kmem_cache_destroy+0x66/0x160 nfsd_file_cache_shutdown+0xc8/0x210 [nfsd] nfsd_destroy_serv+0x251/0x2a0 [nfsd] nfsd_svc+0x125/0x1e0 [nfsd] write_threads+0x16a/0x2a0 [nfsd] nfsctl_transaction_write+0x74/0xa0 [nfsd] vfs_write+0x1a5/0x6d0 ksys_write+0xc1/0x160 do_syscall_64+0x5f/0x170 entry_SYSCALL_64_after_hwframe+0x76/0x7e To resolve this issue, cancel `nfsd_shrinker_work` using synchronous mode in nfs4_state_shutdown_net.

From: Mika Westerberg <mika.westerberg(a)linux.intel.com> stable inclusion from stable-v5.10.225 commit 747bc154577de6e6af4bc99abfa859b8419bb4d8 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAR5FZ CVE: CVE-2024-46702 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… --------------------------------------------------------------- commit e2006140ad2e01a02ed0aff49cc2ae3ceeb11f8d upstream. I noticed that when we do discrete host router NVM upgrade and it gets hot-removed from the PCIe side as a result of NVM firmware authentication, if there is another host connected with enabled paths we hang in tearing them down. This is due to fact that the Thunderbolt networking driver also tries to cleanup the paths and ends up blocking in tb_disconnect_xdomain_paths() waiting for the domain lock. However, at this point we already cleaned the paths in tb_stop() so there is really no need for tb_disconnect_xdomain_paths() to do that anymore. Furthermore it already checks if the XDomain is unplugged and bails out early so take advantage of that and mark the XDomain as unplugged when we remove the parent router.

[PATCH OLK-5.10] RDMA/hns: Fix DCA mmap area PUAF

[PATCH openEuler-22.03-LTS-SP1] bpf, net: Fix a potential race in do_sock_getsockopt()
by Pu Lehui 07 Nov '24

07 Nov '24

From: Tze-nan Wu <Tze-nan.Wu(a)mediatek.com> mainline inclusion from mainline-v6.11-rc7 commit 33f339a1ba54e56bba57ee9a77c71e385ab4825c category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB2EW4 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- There's a potential race when `cgroup_bpf_enabled(CGROUP_GETSOCKOPT)` is false during the execution of `BPF_CGROUP_GETSOCKOPT_MAX_OPTLEN`, but becomes true when `BPF_CGROUP_RUN_PROG_GETSOCKOPT` is called.

[PATCH OLK-6.6] drm/amd/display: Fix index out of bounds in degamma hardware format translation
by Liu Chuang 06 Nov '24

From: Srinivasan Shanmugam <srinivasan.shanmugam(a)amd.com> stable inclusion from stable-v6.6.55 commit 122e3a7a8c7bcbe3aacddd6103f67f9f36bed473 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYR9A CVE: CVE-2024-49894 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit b7e99058eb2e86aabd7a10761e76cae33d22b49f ] Fixes index out of bounds issue in `cm_helper_translate_curve_to_degamma_hw_format` function. The issue could occur when the index 'i' exceeds the number of transfer function points (TRANSFER_FUNC_POINTS). The fix adds a check to ensure 'i' is within bounds before accessing the transfer function points. If 'i' is out of bounds the function returns false to indicate an error.

[PATCH OLK-6.6] sched/fair: Take the scheduling domain into account in select_idle_smt()
by Wenyu Huang 06 Nov '24

06 Nov '24

From: Keisuke Nishimura <keisuke.nishimura(a)inria.fr> stable inclusion from stable-v6.6.23 commit 495b7cb952003973ff1fe4f70639bf3df91fbfb1 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB2B23 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… -------------------------------- [ Upstream commit 8aeaffef8c6eceab0e1498486fdd4f3dc3b7066c ] When picking a CPU on task wakeup, select_idle_smt() has to take into account the scheduling domain of @target. This is because the "isolcpus" kernel command line option can remove CPUs from the domain to isolate them from other SMT siblings. This fix checks if the candidate CPU is in the target scheduling domain. Commit: df3cb4ea1fb6 ("sched/fair: Fix wrong cpu selecting from isolated domain") ... originally introduced this fix by adding the check of the scheduling domain in the loop. However, commit: 3e6efe87cd5cc ("sched/fair: Remove redundant check in select_idle_smt()") ... accidentally removed the check. Bring it back.

[PATCH OLK-5.10] serial: core: Fix atomicity violation in uart_tiocmget
by Yi Yang 06 Nov '24

06 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().

[PATCH OLK-6.6] serial: core: Fix atomicity violation in uart_tiocmget
by Yi Yang 06 Nov '24

06 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-22.03-LTS-SP1] static_call: Handle module init failure correctly in static_call_del_module()
by Gu Bowen 06 Nov '24

06 Nov '24

From: Thomas Gleixner <tglx(a)linutronix.de> stable inclusion from stable-v6.1.113 commit b566c7d8a2de403ccc9d8a06195e19bbb386d0e4 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYR8E CVE: CVE-2024-50002 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 4b30051c4864234ec57290c3d142db7c88f10d8a ] Module insertion invokes static_call_add_module() to initialize the static calls in a module. static_call_add_module() invokes __static_call_init(), which allocates a struct static_call_mod to either encapsulate the built-in static call sites of the associated key into it so further modules can be added or to append the module to the module chain. If that allocation fails the function returns with an error code and the module core invokes static_call_del_module() to clean up eventually added static_call_mod entries. This works correctly, when all keys used by the module were converted over to a module chain before the failure. If not then static_call_del_module() causes a #GP as it blindly assumes that key::mods points to a valid struct static_call_mod. The problem is that key::mods is not a individual struct member of struct static_call_key, it's part of a union to save space: union { /* bit 0: 0 = mods, 1 = sites */ unsigned long type; struct static_call_mod *mods; struct static_call_site *sites; }; key::sites is a pointer to the list of built-in usage sites of the static call. The type of the pointer is differentiated by bit 0. A mods pointer has the bit clear, the sites pointer has the bit set. As static_call_del_module() blidly assumes that the pointer is a valid static_call_mod type, it fails to check for this failure case and dereferences the pointer to the list of built-in call sites, which is obviously bogus. Cure it by checking whether the key has a sites or a mods pointer. If it's a sites pointer then the key is not to be touched. As the sites are walked in the same order as in __static_call_init() the site walk can be terminated because all subsequent sites have not been touched by the init code due to the error exit. If it was converted before the allocation fail, then the inner loop which searches for a module match will find nothing. A fail in the second allocation in __static_call_init() is harmless and does not require special treatment. The first allocation succeeded and converted the key to a module chain. That first entry has mod::mod == NULL and mod::next == NULL, so the inner loop of static_call_del_module() will neither find a module match nor a module chain. The next site in the walk was either already converted, but can't match the module, or it will exit the outer loop because it has a static_call_site pointer and not a static_call_mod pointer.

[PATCH openEuler-1.0-LTS] nfs: fix rpc_task use-after-free when open and close different files concurrently
by Li Lingfeng 06 Nov '24

06 Nov '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB20ED CVE: NA -------------------------------- Commit b5e9ee1ed8bb("[Huawei] NFSv4: release seqid when open failed for nfs4.0") describes a scenario where a file system is forcibly unmounted when different files are opened concurrently. There is another similar issue where performing concurrent operations of opening file B, closing file A, and unmounting while file A is open which can trigger a UAF of rpc_task. T1: OPEN fileB T2: CLOSE fileA nfs4_do_open ... .rpc_call_prepare nfs_wait_on_sequence // insert to sequence list(T1) // This is the first entry, // and continue. nfs4_do_close .rpc_call_prepare nfs_wait_on_sequence // insert to sequence list(T2) // This is the second entry, // and wait. [T3 wake up T2 here] ... rpc_put_task // finish rpc_task and free it .rpc_call_done nfs_release_seqid list_first_entry // get T1 from list rpc_wake_up_queued_task // wake up T1, UAF _nfs4_open_and_get_state _nfs4_open_and_get_state _nfs4_opendata_to_nfs4_state nfs_release_seqid // remove T1 from list T3: UMOUNT nfs_umount_begin rpc_killall_tasks rpc_signal_task // get T2 from clnt->cl_tasks rpc_wake_up_queued_task_set_status rpc_wake_up_task_queue_set_status_locked rpc_wake_up_task_on_wq_queue_action_locked __rpc_do_wake_up_task_on_wq rpc_make_runnable wake_up_bit // wake up T2 Although the rpc_task corresponding to T1 has been freed, its seqid has not been removed from the sequence list. Additionally, even though T2 is the last task in the list, the current logic of nfs_release_seqid allows T2 to access tasks inserted before it, which can trigger UAF. Fix it by using nfs_release_seqid_inorder instead of nfs_release_seqid in nfs4_close_done.

[PATCH OLK-6.6 1/2] bpf: Fail verification for sign-extension of packet data/data_end/data_meta
by Chen Zhongjin 05 Nov '24

05 Nov '24

From: Yonghong Song <yonghong.song(a)linux.dev> mainline inclusion from mainline-v6.12-rc1 commit 92de36080c93296ef9005690705cba260b9bd68a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYPJQ CVE: CVE-2024-47702 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- syzbot reported a kernel crash due to commit 1f1e864b6555 ("bpf: Handle sign-extenstin ctx member accesses"). The reason is due to sign-extension of 32-bit load for packet data/data_end/data_meta uapi field. The original code looks like: r2 = *(s32 *)(r1 + 76) /* load __sk_buff->data */ r3 = *(u32 *)(r1 + 80) /* load __sk_buff->data_end */ r0 = r2 r0 += 8 if r3 > r0 goto +1 ... Note that __sk_buff->data load has 32-bit sign extension. After verification and convert_ctx_accesses(), the final asm code looks like: r2 = *(u64 *)(r1 +208) r2 = (s32)r2 r3 = *(u64 *)(r1 +80) r0 = r2 r0 += 8 if r3 > r0 goto pc+1 ... Note that 'r2 = (s32)r2' may make the kernel __sk_buff->data address invalid which may cause runtime failure. Currently, in C code, typically we have void *data = (void *)(long)skb->data; void *data_end = (void *)(long)skb->data_end; ... and it will generate r2 = *(u64 *)(r1 +208) r3 = *(u64 *)(r1 +80) r0 = r2 r0 += 8 if r3 > r0 goto pc+1 If we allow sign-extension, void *data = (void *)(long)(int)skb->data; void *data_end = (void *)(long)skb->data_end; ... the generated code looks like r2 = *(u64 *)(r1 +208) r2 <<= 32 r2 s>>= 32 r3 = *(u64 *)(r1 +80) r0 = r2 r0 += 8 if r3 > r0 goto pc+1 and this will cause verification failure since "r2 <<= 32" is not allowed as "r2" is a packet pointer. To fix this issue for case r2 = *(s32 *)(r1 + 76) /* load __sk_buff->data */ this patch added additional checking in is_valid_access() callback function for packet data/data_end/data_meta access. If those accesses are with sign-extenstion, the verification will fail.

[PATCH OLK-5.10] drivers/perf: hisi: Enable HiSilicon Erratum 162700402 quirk for HIP09
by Yushan Wang 05 Nov '24

From: Junhao He <hejunhao3(a)huawei.com> mainline inclusion from mainline-v6.9-rc1 commit e10b6976f6b9afdf3564f88c851e42d139bb19c0 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB23U8 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ---------------------------------------------------------------------- HiSilicon UC PMU v2 suffers the erratum 162700402 that the PMU counter cannot be set due to the lack of clock under power saving mode. This will lead to error or inaccurate counts. The clock can be enabled by the PMU global enabling control. This patch tries to fix this by set the UC PMU enable before set event period to turn on the clock, and then restore the UC PMU configuration. The counter register can hold its value without a clock.

[PATCH OLK-5.10] static_call: Handle module init failure correctly in static_call_del_module()
by Gu Bowen 05 Nov '24

05 Nov '24

From: Thomas Gleixner <tglx(a)linutronix.de> stable inclusion from stable-v6.1.113 commit b566c7d8a2de403ccc9d8a06195e19bbb386d0e4 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYR8E CVE: CVE-2024-50002 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 4b30051c4864234ec57290c3d142db7c88f10d8a ] Module insertion invokes static_call_add_module() to initialize the static calls in a module. static_call_add_module() invokes __static_call_init(), which allocates a struct static_call_mod to either encapsulate the built-in static call sites of the associated key into it so further modules can be added or to append the module to the module chain. If that allocation fails the function returns with an error code and the module core invokes static_call_del_module() to clean up eventually added static_call_mod entries. This works correctly, when all keys used by the module were converted over to a module chain before the failure. If not then static_call_del_module() causes a #GP as it blindly assumes that key::mods points to a valid struct static_call_mod. The problem is that key::mods is not a individual struct member of struct static_call_key, it's part of a union to save space: union { /* bit 0: 0 = mods, 1 = sites */ unsigned long type; struct static_call_mod *mods; struct static_call_site *sites; }; key::sites is a pointer to the list of built-in usage sites of the static call. The type of the pointer is differentiated by bit 0. A mods pointer has the bit clear, the sites pointer has the bit set. As static_call_del_module() blidly assumes that the pointer is a valid static_call_mod type, it fails to check for this failure case and dereferences the pointer to the list of built-in call sites, which is obviously bogus. Cure it by checking whether the key has a sites or a mods pointer. If it's a sites pointer then the key is not to be touched. As the sites are walked in the same order as in __static_call_init() the site walk can be terminated because all subsequent sites have not been touched by the init code due to the error exit. If it was converted before the allocation fail, then the inner loop which searches for a module match will find nothing. A fail in the second allocation in __static_call_init() is harmless and does not require special treatment. The first allocation succeeded and converted the key to a module chain. That first entry has mod::mod == NULL and mod::next == NULL, so the inner loop of static_call_del_module() will neither find a module match nor a module chain. The next site in the walk was either already converted, but can't match the module, or it will exit the outer loop because it has a static_call_site pointer and not a static_call_mod pointer.

[PATCH OLK-6.6] l2tp: prevent possible tunnel refcount underflow
by Liu Jian 05 Nov '24

05 Nov '24

From: James Chapman <jchapman(a)katalix.com> mainline inclusion from mainline-v6.12-rc1 commit 24256415d18695b46da06c93135f5b51c548b950 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYR9M CVE: CVE-2024-49940 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ------------------------------------------------- When a session is created, it sets a backpointer to its tunnel. When the session refcount drops to 0, l2tp_session_free drops the tunnel refcount if session->tunnel is non-NULL. However, session->tunnel is set in l2tp_session_create, before the tunnel refcount is incremented by l2tp_session_register, which leaves a small window where session->tunnel is non-NULL when the tunnel refcount hasn't been bumped. Moving the assignment to l2tp_session_register is trivial but l2tp_session_create calls l2tp_session_set_header_len which uses session->tunnel to get the tunnel's encap. Add an encap arg to l2tp_session_set_header_len to avoid using session->tunnel. If l2tpv3 sessions have colliding IDs, it is possible for l2tp_v3_session_get to race with l2tp_session_register and fetch a session which doesn't yet have session->tunnel set.

[PATCH OLK-5.10] l2tp: prevent possible tunnel refcount underflow

From: James Chapman <jchapman(a)katalix.com> mainline inclusion from mainline-v6.12-rc1 commit 24256415d18695b46da06c93135f5b51c548b950 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYR9M CVE: CVE-2024-49940 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ------------------------------------------------- When a session is created, it sets a backpointer to its tunnel. When the session refcount drops to 0, l2tp_session_free drops the tunnel refcount if session->tunnel is non-NULL. However, session->tunnel is set in l2tp_session_create, before the tunnel refcount is incremented by l2tp_session_register, which leaves a small window where session->tunnel is non-NULL when the tunnel refcount hasn't been bumped. Moving the assignment to l2tp_session_register is trivial but l2tp_session_create calls l2tp_session_set_header_len which uses session->tunnel to get the tunnel's encap. Add an encap arg to l2tp_session_set_header_len to avoid using session->tunnel. If l2tpv3 sessions have colliding IDs, it is possible for l2tp_v3_session_get to race with l2tp_session_register and fetch a session which doesn't yet have session->tunnel set.

[PATCH OLK-5.10] static_call: Handle module init failure correctly in static_call_del_module()
by Gu Bowen 05 Nov '24

05 Nov '24

From: Thomas Gleixner <tglx(a)linutronix.de> stable inclusion from stable-v6.1.113 commit b566c7d8a2de403ccc9d8a06195e19bbb386d0e4 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issue/IAYR8E CVE: CVE-2024-50002 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 4b30051c4864234ec57290c3d142db7c88f10d8a ] Module insertion invokes static_call_add_module() to initialize the static calls in a module. static_call_add_module() invokes __static_call_init(), which allocates a struct static_call_mod to either encapsulate the built-in static call sites of the associated key into it so further modules can be added or to append the module to the module chain. If that allocation fails the function returns with an error code and the module core invokes static_call_del_module() to clean up eventually added static_call_mod entries. This works correctly, when all keys used by the module were converted over to a module chain before the failure. If not then static_call_del_module() causes a #GP as it blindly assumes that key::mods points to a valid struct static_call_mod. The problem is that key::mods is not a individual struct member of struct static_call_key, it's part of a union to save space: union { /* bit 0: 0 = mods, 1 = sites */ unsigned long type; struct static_call_mod *mods; struct static_call_site *sites; }; key::sites is a pointer to the list of built-in usage sites of the static call. The type of the pointer is differentiated by bit 0. A mods pointer has the bit clear, the sites pointer has the bit set. As static_call_del_module() blidly assumes that the pointer is a valid static_call_mod type, it fails to check for this failure case and dereferences the pointer to the list of built-in call sites, which is obviously bogus. Cure it by checking whether the key has a sites or a mods pointer. If it's a sites pointer then the key is not to be touched. As the sites are walked in the same order as in __static_call_init() the site walk can be terminated because all subsequent sites have not been touched by the init code due to the error exit. If it was converted before the allocation fail, then the inner loop which searches for a module match will find nothing. A fail in the second allocation in __static_call_init() is harmless and does not require special treatment. The first allocation succeeded and converted the key to a module chain. That first entry has mod::mod == NULL and mod::next == NULL, so the inner loop of static_call_del_module() will neither find a module match nor a module chain. The next site in the walk was either already converted, but can't match the module, or it will exit the outer loop because it has a static_call_site pointer and not a static_call_mod pointer.

[PATCH OLK-6.6] bpf: Fail verification for sign-extension of packet data/data_end/data_meta
by Chen Zhongjin 04 Nov '24

04 Nov '24

From: Yonghong Song <yonghong.song(a)linux.dev> mainline inclusion from mainline-v6.12-rc1 commit 92de36080c93296ef9005690705cba260b9bd68a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYPJQ CVE: CVE-2024-47702 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- syzbot reported a kernel crash due to commit 1f1e864b6555 ("bpf: Handle sign-extenstin ctx member accesses"). The reason is due to sign-extension of 32-bit load for packet data/data_end/data_meta uapi field. The original code looks like: r2 = *(s32 *)(r1 + 76) /* load __sk_buff->data */ r3 = *(u32 *)(r1 + 80) /* load __sk_buff->data_end */ r0 = r2 r0 += 8 if r3 > r0 goto +1 ... Note that __sk_buff->data load has 32-bit sign extension. After verification and convert_ctx_accesses(), the final asm code looks like: r2 = *(u64 *)(r1 +208) r2 = (s32)r2 r3 = *(u64 *)(r1 +80) r0 = r2 r0 += 8 if r3 > r0 goto pc+1 ... Note that 'r2 = (s32)r2' may make the kernel __sk_buff->data address invalid which may cause runtime failure. Currently, in C code, typically we have void *data = (void *)(long)skb->data; void *data_end = (void *)(long)skb->data_end; ... and it will generate r2 = *(u64 *)(r1 +208) r3 = *(u64 *)(r1 +80) r0 = r2 r0 += 8 if r3 > r0 goto pc+1 If we allow sign-extension, void *data = (void *)(long)(int)skb->data; void *data_end = (void *)(long)skb->data_end; ... the generated code looks like r2 = *(u64 *)(r1 +208) r2 <<= 32 r2 s>>= 32 r3 = *(u64 *)(r1 +80) r0 = r2 r0 += 8 if r3 > r0 goto pc+1 and this will cause verification failure since "r2 <<= 32" is not allowed as "r2" is a packet pointer. To fix this issue for case r2 = *(s32 *)(r1 + 76) /* load __sk_buff->data */ this patch added additional checking in is_valid_access() callback function for packet data/data_end/data_meta access. If those accesses are with sign-extenstion, the verification will fail.

If we break for_each_pci_dev() loop with pdev not NULL, we need to call pci_dev_put() to decrease the reference count. Add the missing pci_dev_put() for the error path to avoid reference count leak.

[PATCH OLK-6.6] bpftool: Fix undefined behavior in qsort(NULL, 0, ...)
by Xiaomeng Zhang 04 Nov '24

04 Nov '24

From: Kuan-Wei Chiu <visitorckw(a)gmail.com> stable inclusion from stable-v6.6.55 commit c2d9f9a7837ab29ccae0c42252f17d436bf0a501 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB0R30 CVE: CVE-2024-49987 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit f04e2ad394e2755d0bb2d858ecb5598718bf00d5 ] When netfilter has no entry to display, qsort is called with qsort(NULL, 0, ...). This results in undefined behavior, as UBSan reports: net.c:827:2: runtime error: null pointer passed as argument 1, which is declared to never be null Although the C standard does not explicitly state whether calling qsort with a NULL pointer when the size is 0 constitutes undefined behavior, Section 7.1.4 of the C standard (Use of library functions) mentions: "Each of the following statements applies unless explicitly stated otherwise in the detailed descriptions that follow: If an argument to a function has an invalid value (such as a value outside the domain of the function, or a pointer outside the address space of the program, or a null pointer, or a pointer to non-modifiable storage when the corresponding parameter is not const-qualified) or a type (after promotion) not expected by a function with variable number of arguments, the behavior is undefined." To avoid this, add an early return when nf_link_info is NULL to prevent calling qsort with a NULL pointer.

This caused an issue when processing transient non-fatal errors. igb_io_resume(), which is called after igb_io_error_detected(), assumes that device is brought down by igb_io_error_detected() if the interface is up.

[PATCH openEuler-22.03-LTS-SP1] vhost/scsi: null-ptr-dereference in vhost_scsi_get_req()
by Kaixiong Yu 04 Nov '24

From: Haoran Zhang <wh1sper(a)zju.edu.cn> stable inclusion from stable-v5.10.227 commit 6592347f06e2b19a624270a85ad4b3ae48c3b241 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYR8T CVE: CVE-2024-49863 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 221af82f606d928ccef19a16d35633c63026f1be upstream. Since commit 3f8ca2e115e5 ("vhost/scsi: Extract common handling code from control queue handler") a null pointer dereference bug can be triggered when guest sends an SCSI AN request. In vhost_scsi_ctl_handle_vq(), `vc.target` is assigned with `&v_req.tmf.lun[1]` within a switch-case block and is then passed to vhost_scsi_get_req() which extracts `vc->req` and `tpg`. However, for a `VIRTIO_SCSI_T_AN_*` request, tpg is not required, so `vc.target` is set to NULL in this branch. Later, in vhost_scsi_get_req(), `vc->target` is dereferenced without being checked, leading to a null pointer dereference bug. This bug can be triggered from guest. When this bug occurs, the vhost_worker process is killed while holding `vq->mutex` and the corresponding tpg will remain occupied indefinitely.

[PATCH OLK-6.6] mm/mremap: fix move_normal_pmd/retract_page_tables race
by Kaixiong Yu 04 Nov '24

04 Nov '24

From: Jann Horn <jannh(a)google.com> stable inclusion from stable-v6.6.58 commit 17396e32f975130b3e6251f024c8807d192e4c3e category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAZ7TE CVE: CVE-2024-50066 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 6fa1066fc5d00cb9f1b0e83b7ff6ef98d26ba2aa upstream. In mremap(), move_page_tables() looks at the type of the PMD entry and the specified address range to figure out by which method the next chunk of page table entries should be moved. At that point, the mmap_lock is held in write mode, but no rmap locks are held yet. For PMD entries that point to page tables and are fully covered by the source address range, move_pgt_entry(NORMAL_PMD, ...) is called, which first takes rmap locks, then does move_normal_pmd(). move_normal_pmd() takes the necessary page table locks at source and destination, then moves an entire page table from the source to the destination. The problem is: The rmap locks, which protect against concurrent page table removal by retract_page_tables() in the THP code, are only taken after the PMD entry has been read and it has been decided how to move it. So we can race as follows (with two processes that have mappings of the same tmpfs file that is stored on a tmpfs mount with huge=advise); note that process A accesses page tables through the MM while process B does it through the file rmap: process A process B ========= ========= mremap mremap_to move_vma move_page_tables get_old_pmd alloc_new_pmd *** PREEMPT *** madvise(MADV_COLLAPSE) do_madvise madvise_walk_vmas madvise_vma_behavior madvise_collapse hpage_collapse_scan_file collapse_file retract_page_tables i_mmap_lock_read(mapping) pmdp_collapse_flush i_mmap_unlock_read(mapping) move_pgt_entry(NORMAL_PMD, ...) take_rmap_locks move_normal_pmd drop_rmap_locks When this happens, move_normal_pmd() can end up creating bogus PMD entries in the line `pmd_populate(mm, new_pmd, pmd_pgtable(pmd))`. The effect depends on arch-specific and machine-specific details; on x86, you can end up with physical page 0 mapped as a page table, which is likely exploitable for user->kernel privilege escalation. Fix the race by letting process B recheck that the PMD still points to a page table after the rmap locks have been taken. Otherwise, we bail and let the caller fall back to the PTE-level copying path, which will then bail immediately at the pmd_none() check. Bug reachability: Reaching this bug requires that you can create shmem/file THP mappings - anonymous THP uses different code that doesn't zap stuff under rmap locks. File THP is gated on an experimental config flag (CONFIG_READ_ONLY_THP_FOR_FS), so on normal distro kernels you need shmem THP to hit this bug. As far as I know, getting shmem THP normally requires that you can mount your own tmpfs with the right mount flags, which would require creating your own user+mount namespace; though I don't know if some distros maybe enable shmem THP by default or something like that. Bug impact: This issue can likely be used for user->kernel privilege escalation when it is reachable.

[PATCH OLK-6.6] bpf: Fail verification for sign-extension of packet data/data_end/data_meta
by Chen Zhongjin 04 Nov '24

04 Nov '24

From: Yonghong Song <yonghong.song(a)linux.dev> mainline inclusion from mainline-v6.12-rc1 commit 92de36080c93296ef9005690705cba260b9bd68a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYPJQ CVE: CVE-2024-47702 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- syzbot reported a kernel crash due to commit 1f1e864b6555 ("bpf: Handle sign-extenstin ctx member accesses"). The reason is due to sign-extension of 32-bit load for packet data/data_end/data_meta uapi field. The original code looks like: r2 = *(s32 *)(r1 + 76) /* load __sk_buff->data */ r3 = *(u32 *)(r1 + 80) /* load __sk_buff->data_end */ r0 = r2 r0 += 8 if r3 > r0 goto +1 ... Note that __sk_buff->data load has 32-bit sign extension. After verification and convert_ctx_accesses(), the final asm code looks like: r2 = *(u64 *)(r1 +208) r2 = (s32)r2 r3 = *(u64 *)(r1 +80) r0 = r2 r0 += 8 if r3 > r0 goto pc+1 ... Note that 'r2 = (s32)r2' may make the kernel __sk_buff->data address invalid which may cause runtime failure. Currently, in C code, typically we have void *data = (void *)(long)skb->data; void *data_end = (void *)(long)skb->data_end; ... and it will generate r2 = *(u64 *)(r1 +208) r3 = *(u64 *)(r1 +80) r0 = r2 r0 += 8 if r3 > r0 goto pc+1 If we allow sign-extension, void *data = (void *)(long)(int)skb->data; void *data_end = (void *)(long)skb->data_end; ... the generated code looks like r2 = *(u64 *)(r1 +208) r2 <<= 32 r2 s>>= 32 r3 = *(u64 *)(r1 +80) r0 = r2 r0 += 8 if r3 > r0 goto pc+1 and this will cause verification failure since "r2 <<= 32" is not allowed as "r2" is a packet pointer. To fix this issue for case r2 = *(s32 *)(r1 + 76) /* load __sk_buff->data */ this patch added additional checking in is_valid_access() callback function for packet data/data_end/data_meta access. If those accesses are with sign-extenstion, the verification will fail.

After verification and convert_ctx_accesses(), the final asm code looks like: r2 = *(u64 *)(r1 +208) r2 = (s32)r2 r3 = *(u64 *)(r1 +80) r0 = r2 r0 += 8 if r3 > r0 goto pc+1 ... Note that 'r2 = (s32)r2' may make the kernel __sk_buff->data address invalid which may cause runtime failure. Currently, in C code, typically we have void *data = (void *)(long)skb->data; void *data_end = (void *)(long)skb->data_end; ... and it will generate r2 = *(u64 *)(r1 +208) r3 = *(u64 *)(r1 +80) r0 = r2 r0 += 8 if r3 > r0 goto pc+1 If we allow sign-extension, void *data = (void *)(long)(int)skb->data; void *data_end = (void *)(long)skb->data_end; ... the generated code looks like r2 = *(u64 *)(r1 +208) r2 <<= 32 r2 s>>= 32 r3 = *(u64 *)(r1 +80) r0 = r2 r0 += 8 if r3 > r0 goto pc+1 and this will cause verification failure since "r2 <<= 32" is not allowed as "r2" is a packet pointer. To fix this issue for case r2 = *(s32 *)(r1 + 76) /* load __sk_buff->data */ this patch added additional checking in is_valid_access() callback function for packet data/data_end/data_meta access. If those accesses are with sign-extenstion, the verification will fail.

[PATCH OLK-6.6] mm: gup: stop abusing try_grab_folio

From: Yang Shi <yang(a)os.amperecomputing.com> stable inclusion from stable-v6.6.47 commit 26273f5f4cf68b29414e403837093408a9c98e1f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAN4MO CVE: CVE-2024-44943 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit f442fa6141379a20b48ae3efabee827a3d260787 upstream. A kernel warning was reported when pinning folio in CMA memory when launching SEV virtual machine. The splat looks like: [ 464.325306] WARNING: CPU: 13 PID: 6734 at mm/gup.c:1313 __get_user_pages+0x423/0x520 [ 464.325464] CPU: 13 PID: 6734 Comm: qemu-kvm Kdump: loaded Not tainted 6.6.33+ #6 [ 464.325477] RIP: 0010:__get_user_pages+0x423/0x520 [ 464.325515] Call Trace: [ 464.325520] <TASK> [ 464.325523] ? __get_user_pages+0x423/0x520 [ 464.325528] ? __warn+0x81/0x130 [ 464.325536] ? __get_user_pages+0x423/0x520 [ 464.325541] ? report_bug+0x171/0x1a0 [ 464.325549] ? handle_bug+0x3c/0x70 [ 464.325554] ? exc_invalid_op+0x17/0x70 [ 464.325558] ? asm_exc_invalid_op+0x1a/0x20 [ 464.325567] ? __get_user_pages+0x423/0x520 [ 464.325575] __gup_longterm_locked+0x212/0x7a0 [ 464.325583] internal_get_user_pages_fast+0xfb/0x190 [ 464.325590] pin_user_pages_fast+0x47/0x60 [ 464.325598] sev_pin_memory+0xca/0x170 [kvm_amd] [ 464.325616] sev_mem_enc_register_region+0x81/0x130 [kvm_amd] Per the analysis done by yangge, when starting the SEV virtual machine, it will call pin_user_pages_fast(..., FOLL_LONGTERM, ...) to pin the memory. But the page is in CMA area, so fast GUP will fail then fallback to the slow path due to the longterm pinnalbe check in try_grab_folio(). The slow path will try to pin the pages then migrate them out of CMA area. But the slow path also uses try_grab_folio() to pin the page, it will also fail due to the same check then the above warning is triggered. In addition, the try_grab_folio() is supposed to be used in fast path and it elevates folio refcount by using add ref unless zero. We are guaranteed to have at least one stable reference in slow path, so the simple atomic add could be used. The performance difference should be trivial, but the misuse may be confusing and misleading. Redefined try_grab_folio() to try_grab_folio_fast(), and try_grab_page() to try_grab_folio(), and use them in the proper paths. This solves both the abuse and the kernel warning. The proper naming makes their usecase more clear and should prevent from abusing in the future. peterx said: : The user will see the pin fails, for gpu-slow it further triggers the WARN : right below that failure (as in the original report): : : folio = try_grab_folio(page, page_increm - 1, : foll_flags); : if (WARN_ON_ONCE(!folio)) { <------------------------ here : /* : * Release the 1st page ref if the : * folio is problematic, fail hard. : */ : gup_put_folio(page_folio(page), 1, : foll_flags); : ret = -EFAULT; : goto out; : } [1] https://lore.kernel.org/linux-mm/1719478388-31917-1-git-send-email-yangge11… [shy828301(a)gmail.com: fix implicit declaration of function try_grab_folio_fast] Link: https://lkml.kernel.org/r/CAHbLzkowMSso-4Nufc9hcMehQsK9PNz3OSu-+eniU-2Mm-xj… Link: https://lkml.kernel.org/r/20240628191458.2605553-1-yang@os.amperecomputing.… Fixes: 57edfcfd3419 ("mm/gup: accelerate thp gup even for "pages != NULL"") Signed-off-by: Yang Shi <yang(a)os.amperecomputing.com> Reported-by: yangge <yangge1116(a)126.com> Cc: Christoph Hellwig <hch(a)infradead.org> Cc: David Hildenbrand <david(a)redhat.com> Cc: Peter Xu <peterx(a)redhat.com> Cc: <stable(a)vger.kernel.org> [6.6+] Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Conflicts: mm/gup.c [Context conflicts when removing old try_grab_folio().] Signed-off-by: Jinjiang Tu <tujinjiang(a)huawei.com> --- mm/gup.c | 251 ++++++++++++++++++++++++----------------------- mm/huge_memory.c | 6 +- mm/hugetlb.c | 2 +- mm/internal.h | 4 +- 4 files changed, 135 insertions(+), 128 deletions(-) diff --git a/mm/gup.c b/mm/gup.c index 16f029cd8544..33e8e66b3a77 100644 --- a/mm/gup.c +++ b/mm/gup.c @@ -97,95 +97,6 @@ static inline struct folio *try_get_folio(struct page *page, int refs) return folio; } -/** - * try_grab_folio() - Attempt to get or pin a folio. - * @page: pointer to page to be grabbed - * @refs: the value to (effectively) add to the folio's refcount - * @flags: gup flags: these are the FOLL_* flag values. - * - * "grab" names in this file mean, "look at flags to decide whether to use - * FOLL_PIN or FOLL_GET behavior, when incrementing the folio's refcount. - * - * Either FOLL_PIN or FOLL_GET (or neither) must be set, but not both at the - * same time.
