[PATCH OLK-6.6] smb: client: Fix netns refcount imbalance causing leaks and use-after-free
by Wang Zhaolong 25 Feb '25

25 Feb '25

maillist inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBNCLL CVE: NA Reference: https://lore.kernel.org/linux-cifs/CAH2r5muqxgPy=n4Aks_k-2goEZmmD10Dx3u3jgO… --------------------------------------------- Commit ef7134c7fc48 ("smb: client: Fix use-after-free of network namespace.") attempted to fix a netns use-after-free issue by manually adjusting reference counts via sk->sk_net_refcnt and sock_inuse_add(). However, a later commit e9f2517a3e18 ("smb: client: fix TCP timers deadlock after rmmod") pointed out that the approach of manually setting sk->sk_net_refcnt in the first commit was technically incorrect, as sk->sk_net_refcnt should only be set for user sockets. It led to issues like TCP timers not being cleared properly on close. The second commit moved to a model of just holding an extra netns reference for server->ssocket using get_net(), and dropping it when the server is torn down. But there remain some gaps in the get_net()/put_net() balancing added by these commits. The incomplete reference handling in these fixes results in two issues: 1. Netns refcount leaks[1] The problem process is as follows: ``` mount.cifs cifsd cifs_do_mount cifs_mount cifs_mount_get_session cifs_get_tcp_session get_net() /* First get net. */ ip_connect generic_ip_connect /* Try port 445 */ get_net() ->connect() /* Failed */ put_net() generic_ip_connect /* Try port 139 */ get_net() /* Missing matching put_net() for this get_net().*/ cifs_get_smb_ses cifs_negotiate_protocol smb2_negotiate SMB2_negotiate cifs_send_recv wait_for_response cifs_demultiplex_thread cifs_read_from_socket cifs_readv_from_socket cifs_reconnect cifs_abort_connection sock_release(); server->ssocket = NULL; /* Missing put_net() here. */ generic_ip_connect get_net() ->connect() /* Failed */ put_net() sock_release(); server->ssocket = NULL; free_rsp_buf ... clean_demultiplex_info /* It's only called once here. */ put_net() ``` When cifs_reconnect() is triggered, the server->ssocket is released without a corresponding put_net() for the reference acquired in generic_ip_connect() before. it ends up calling generic_ip_connect() again to retry get_net(). After that, server->ssocket is set to NULL in the error path of generic_ip_connect(), and the net count cannot be released in the final clean_demultiplex_info() function. 2. Potential use-after-free The current refcounting scheme can lead to a potential use-after-free issue in the following scenario: ``` cifs_do_mount cifs_mount cifs_mount_get_session cifs_get_tcp_session get_net() /* First get net */ ip_connect generic_ip_connect get_net() bind_socket kernel_bind /* failed */ put_net() /* after out_err_crypto_release label */ put_net() /* after out_err label */ put_net() ``` In the exception handling process where binding the socket fails, the get_net() and put_net() calls are unbalanced, which may cause the server->net reference count to drop to zero and be prematurely released. To address both issues, this patch ties the netns reference counting to the server->ssocket and server lifecycles. The extra reference is now acquired when the server or socket is created, and released when the socket is destroyed or the server is torn down.

[PATCH openEuler-25.03 v3 0/4] Add TrIO support in EROFS
by Hongbo Li 25 Feb '25

25 Feb '25

TrIO can accelerate the cold start of containers during on-demand loading. It aggregates the read I/O operations required for container runtime during the first container launch. In the following startups, TrIO pulls the necessary I/O data to the container node in a single large I/O operation and uses this I/O information to construct the runtime rootfs. By improving the efficiency of network I/O, TrIO speeds up container startup in on-demand loading scenarios. TrIO consists of both kernel-space and user-space code. The kernel-space code has been adapted at the overlayfs layer, introducing the CONFIG_EROFS_TRIO configuration to provide isolation. The user-space code requires adaptation by the user, and detailed usage methods are introduced in the tools/trio/README.md section. Patches 1~2 correspond to the kernel adaptations, while patches 3~4 are the scripts and best practices that TrIO relies on for its operation. v3: - Obtain and keep the trio_object in open. - Only close readahead in trio case.

[PATCH v3 openEuler-25.03 00/20] mm: arm64: Add kernel replication feature
by Denis Darvish 25 Feb '25

25 Feb '25

This patchset implements initial support of kernel text and rodata replication for AArch64. openEuler 25.03 is used as a baseline. Current implementation supports next functionality: 1. Replicated kernel text and rodata per-NUMA node 2. Vmalloc is able to work with replicated areas, so kernel modules text and rodata also replicated during modules loading stage. 3. BPF handlers are not replicated by default, but this can be easily done by using existent APIs. 4. KPROBES, KGDB and all functionality that depends on kernel text patching work without any limitation. 5. KPTI, KASLR, and KASAN fully supported. 6. Replicates parts of translation table related to replicated text and rodata. 7. 4K and 64K pages are supported. Translation tables synchronization is necessary only in several special cases: 1. Kernel boot 2. Modules deployment 3. Any allocation in user space that require new PUD/P4D In current design mutable kernel data modifications don't require synchronization between translation tables due to on 64-bit platforms all physical memory already mapped in kernel space and this mapping is persistent. In user space the translation tables synchronizations are quite rare due to the only case is new PUD/P4D allocation. At the current stage only the PGD layer is replicated for the user space. Please refer to the next pics.

Not all paging modes are supported, for example, the 16K 4-level table is not supported right now. 2. Replication support in vmalloc, possibly, can be optimized in future. 3. Module APIs currently have lack of memory policies support. This part will be fixed in future.
