[PATCH OLK-6.6 1/5] driver/svm: support SVSP feature, interface definition
by Yuan Can 23 Feb '24

23 Feb '24

From: Zhou Guanghui <zhouguanghui1(a)huawei.com> ascend inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I931MI CVE: NA ----------------------------------------------------------------- In the SVA scenario, the master device of the SMMU can access the address space of the process by the operation of binding process. The page table of the process is shared by the MMU and SMMU, In this case, if some addrss range cannot be accessed through the MMU, access to this address range needs to be isolated from the process page table. If the default domain of the SMMU is used, the isolation can be achieved. However, the address space created by default domain do not like the address space of the process which can be shared by multiple SMMUs. Therefore, we add a shadow virtual space of process. This address space is used only by the SMMU.

[PATCH OLK-6.6 0/9] Support PV sched feature
by lishusen 22 Feb '24

22 Feb '24

PV sched supports the vCPU preemption check to enhance lock performance on overcommitted hosts.

[OLK-6.6 v3 1/2] RDMA/hns: Append SCC context to the raw dump of QP Resource

From: wenglianfa <wenglianfa(a)huawei.com> driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I8B8HH -------------------------------------------------------------------------- SCCC (SCC Context) is a context with QP granularity that contains information about congestion control. Dump SCCC and QPC together to improve troubleshooting. When dumping raw QPC with rdmatool, there will be a total of 576B data output, where the first 512B is QPC and the last 64B is SCCC. When congestion control is disabled, the 64B SCCC will be all 0.

[PATCH OLK-5.10] binder: fix use-after-free in shinker's callback
by Ze Zuo 22 Feb '24

22 Feb '24

From: Carlos Llamas <cmllamas(a)google.com> stable inclusion from stable-v5.10.209 commit c8c1158ffb007197f31f9d9170cf13e4f34cbb5c category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I92HXG CVE: CVE-2023-52438 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 3f489c2067c5824528212b0fc18b28d51332d906 upstream. The mmap read lock is used during the shrinker's callback, which means that using alloc->vma pointer isn't safe as it can race with munmap(). As of commit dd2283f2605e ("mm: mmap: zap pages with read mmap_sem in munmap") the mmap lock is downgraded after the vma has been isolated. I was able to reproduce this issue by manually adding some delays and triggering page reclaiming through the shrinker's debug sysfs. The following KASAN report confirms the UAF: ================================================================== BUG: KASAN: slab-use-after-free in zap_page_range_single+0x470/0x4b8 Read of size 8 at addr ffff356ed50e50f0 by task bash/478 CPU: 1 PID: 478 Comm: bash Not tainted 6.6.0-rc5-00055-g1c8b86a3799f-dirty #70 Hardware name: linux,dummy-virt (DT) Call trace: zap_page_range_single+0x470/0x4b8 binder_alloc_free_page+0x608/0xadc __list_lru_walk_one+0x130/0x3b0 list_lru_walk_node+0xc4/0x22c binder_shrink_scan+0x108/0x1dc shrinker_debugfs_scan_write+0x2b4/0x500 full_proxy_write+0xd4/0x140 vfs_write+0x1ac/0x758 ksys_write+0xf0/0x1dc __arm64_sys_write+0x6c/0x9c Allocated by task 492: kmem_cache_alloc+0x130/0x368 vm_area_alloc+0x2c/0x190 mmap_region+0x258/0x18bc do_mmap+0x694/0xa60 vm_mmap_pgoff+0x170/0x29c ksys_mmap_pgoff+0x290/0x3a0 __arm64_sys_mmap+0xcc/0x144 Freed by task 491: kmem_cache_free+0x17c/0x3c8 vm_area_free_rcu_cb+0x74/0x98 rcu_core+0xa38/0x26d4 rcu_core_si+0x10/0x1c __do_softirq+0x2fc/0xd24 Last potentially related work creation: __call_rcu_common.constprop.0+0x6c/0xba0 call_rcu+0x10/0x1c vm_area_free+0x18/0x24 remove_vma+0xe4/0x118 do_vmi_align_munmap.isra.0+0x718/0xb5c do_vmi_munmap+0xdc/0x1fc __vm_munmap+0x10c/0x278 __arm64_sys_munmap+0x58/0x7c Fix this issue by performing instead a vma_lookup() which will fail to find the vma that was isolated before the mmap lock downgrade. Note that this option has better performance than upgrading to a mmap write lock which would increase contention. Plus, mmap_write_trylock() has been recently removed anyway.

Respond to empty requests right when populating fragments; all further processing is fragment based and hence won't encounter these empty requests anymore. In a way this should have been that way from the beginning: When no data is to be transferred for a particular request, there's not even a point in validating the respective grant ref. That's no different from e.g. passing NULL into memcpy() when at the same time the size is 0. This is XSA-448 / CVE-2023-46838.

[PATCH openEuler-1.0-LTS] tty: fix return value for unsupported ioctls
by Yi Yang 19 Feb '24

From: Johan Hovold <johan(a)kernel.org> stable inclusion from stable-v4.19.191 commit 76d7fc0857bc4033415fcad905db13753d0febc7 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I926JG CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 1b8b20868a6d64cfe8174a21b25b74367bdf0560 ] Drivers should return -ENOTTY ("Inappropriate I/O control operation") when an ioctl isn't supported, while -EINVAL is used for invalid arguments. Fix up the TIOCMGET, TIOCMSET and TIOCGICOUNT helpers which returned -EINVAL when a tty driver did not implement the corresponding operations. Note that the TIOCMGET and TIOCMSET helpers predate git and do not get a corresponding Fixes tag below.

From: Chengfeng Ye <dg573847474(a)gmail.com> stable inclusion from stable-v5.10.188 commit 6d2243ab783bf79d1d674ff0ca26229233c56508 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8WZLA CVE: CVE-2024-0639 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 6feb37b3b06e9049e20dcf7e23998f92c9c5be9a ] As &net->sctp.addr_wq_lock is also acquired by the timer sctp_addr_wq_timeout_handler() in protocal.c, the same lock acquisition at sctp_auto_asconf_init() seems should disable irq since it is called from sctp_accept() under process context. Possible deadlock scenario: sctp_accept() -> sctp_sock_migrate() -> sctp_auto_asconf_init() -> spin_lock(&net->sctp.addr_wq_lock) <timer interrupt> -> sctp_addr_wq_timeout_handler() -> spin_lock_bh(&net->sctp.addr_wq_lock); (deadlock here) This flaw was found using an experimental static analysis tool we are developing for irq-related deadlock. The tentative patch fix the potential deadlock by spin_lock_bh().
