From: Wenwen Wang <wenwen@xxxxxxxxxx> commit b4a81b87a4cfe2bb26a4a943b748d96a43ef20e8 upstream. In ecryptfs_init_messaging(), if the allocation for 'ecryptfs_msg_ctx_arr' fails, the previously allocated 'ecryptfs_daemon_hash' is not deallocated, leading to a memory leak bug. To fix this issue, free 'ecryptfs_daemon_hash' before returning the error.
