[PATCH OLK-6.6] cifs: Prevent NULL pointer dereference caused by cifs_sb->rsize is 0
by Wang Zhaolong 25 Feb '25

25 Feb '25

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBO3FG -------------------------------- When cifs_sb->rsize is 0, cifs_send_async_read() fails to allocate the pages array using iov_iter_get_pages_alloc(), resulting in data->pages being NULL. This eventually triggers a NULL pointer dereference in the callback function uncached_fill_pages(). cifs_sb->rsize is set to the minimum value between SMB3_DEFAULT_IOSIZE and server->max_read. SMB3_DEFAULT_IOSIZE is 4MB. There are two reasons that cause cifs_sb->rsize to be 0: 1. During the negotiation process, if the server returns an rsp->MaxReadSize of 0, server->max_read is assigned 0. And the calculated value of cifs_sb->rsize becomes 0. 2. In the cifsd thread, if cifs_reconnect() is invoked, server->max_read is set to 0. Prior to the completion of the reconnection process, the calculated value of cifs_sb->rsize becomes 0. It is important to note that cifs_sb->rsize is only set to 0 during the mount phase. Therefore, a straightforward approach to prevent potential NULL pointer dereferences in the future is to implement a check for cifs_sb->rsize during the mount stage. If the value is found to be 0, the mount process should exit early to avoid any subsequent NULL pointer dereferences.

[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.
