Pull cred refcount updates from Christian Brauner: "For the v6.13 cycle we switched overlayfs to a variant of override_creds() that doesn't take an extra reference. To this end the {override,revert}_creds_light() helpers were introduced. This generalizes the idea behind {override,revert}_creds_light() to the {override,revert}_creds() helpers. Afterwards overriding and reverting credentials is reference count free unless the caller explicitly takes a reference. All callers have been appropriately ported" * tag 'kernel-6.14-rc1.cred' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: (30 commits) cred: fold get_new_cred_many() into get_cred_many() cred: remove unused get_new_cred() nfsd: avoid pointless cred reference count bump cachefiles: avoid pointless cred reference count bump dns_resolver: avoid pointless cred reference count bump trace: avoid pointless cred reference count bump cgroup: avoid pointless cred reference count bump acct: avoid pointless reference count bump io_uring: avoid pointless cred reference count bump smb: avoid pointless cred reference count bump cifs: avoid pointless cred reference count bump cifs: avoid pointless cred reference count bump ovl: avoid pointless cred reference count bump open: avoid pointless cred reference count bump nfsfh: avoid pointless cred reference count bump nfs/nfs4recover: avoid pointless cred reference count bump nfs/nfs4idmap: avoid pointless reference count bump nfs/localio: avoid pointless cred reference count bumps coredump: avoid pointless cred reference count bump binfmt_misc: avoid pointless cred reference count bump ...

ksmbd: fix integer overflows on 32 bit systems

2025-01-16T05:24:51Z

On 32bit systems the addition operations in ipc_msg_alloc() can potentially overflow leading to memory corruption. Add bounds checking using KSMBD_IPC_MAX_PAYLOAD to avoid overflow.

ksmbd: browse interfaces list on FSCTL_QUERY_INTERFACE_INFO IOCTL

2025-01-16T05:24:51Z

ksmbd.mount will give each interfaces list and bind_interfaces_only flags to ksmbd server. Previously, the interfaces list was sent only when bind_interfaces_only was enabled. ksmbd server browse only interfaces list given from ksmbd.conf on FSCTL_QUERY_INTERFACE_INFO IOCTL.

ksmbd: Remove unused functions

2025-01-16T05:24:51Z

ksmbd_rpc_rap() was added in 2021 as part of commit 0626e6641f6b ("cifsd: add server handler for central processing and tranport layers") ksmbd_vfs_posix_lock_wait_timeout() was added in 2021 as part of commit f44158485826 ("cifsd: add file operations") both have remained unused. Remove them. Signed-off-by: Dr. David Alan Gilbert Acked-by: Namjae Jeon Signed-off-by: Steve French

ksmbd: fix unexpectedly changed path in ksmbd_vfs_kern_path_locked

2025-01-07T23:29:17Z

When `ksmbd_vfs_kern_path_locked` met an error and it is not the last entry, it will exit without restoring changed path buffer. But later this buffer may be used as the filename for creation.

ksmbd: fix a missing return value check bug

2025-01-06T02:43:37Z

In the smb2_send_interim_resp(), if ksmbd_alloc_work_struct() fails to allocate a node, it returns a NULL pointer to the in_work pointer. This can lead to an illegal memory write of in_work->response_buf when allocate_interim_rsp_buf() attempts to perform a kzalloc() on it. To address this issue, incorporating a check for the return value of ksmbd_alloc_work_struct() ensures that the function returns immediately upon allocation failure, thereby preventing the aforementioned illegal memory access.

ksmbd: conn lock to serialize smb2 negotiate

2024-12-16T04:20:03Z

If client send parallel smb2 negotiate request on same connection, ksmbd_conn can be racy. smb2 negotiate handling that are not performance-related can be serialized with conn lock. Signed-off-by: Namjae Jeon Signed-off-by: Steve French
