* ksmbd: add support for negotiating signing algorithmNamjae Jeon2021-07-221-0/+4
| | | | | | | | | | | | | | Support for faster packet signing (using GMAC instead of CMAC) can now be negotiated to some newer servers, including Windows. See MS-SMB2 section 2.2.3.17. This patch adds support for sending the new negotiate context with two supported signing algorithms(AES-CMAC, HMAC-SHA256). If client add support for AES_GMAC, Server will be supported later depend on it. Signed-off-by: Namjae Jeon <namjae.jeon@samsung.com> Signed-off-by: Steve French <stfrench@microsoft.com>
* ksmbd: reorder and document on-disk and netlink structures in headersNamjae Jeon2021-06-301-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reorder and document on-disk and netlink structures in headers. This is a userspace ABI to communicate data between ksmbd and user IPC daemon using netlink. This is added to track and cache user account DB and share configuration info from userspace. - KSMBD_EVENT_HEARTBEAT_REQUEST(ksmbd_heartbeat) This event is to check whether user IPC daemon is alive. If user IPC daemon is dead, ksmbd keep existing connection till disconnecting and new connection will be denied. - KSMBD_EVENT_STARTING_UP(ksmbd_startup_request) This event is to receive the information that initializes the ksmbd server from the user IPC daemon and to start the server. The global section parameters are given from smb.conf as initialization information. - KSMBD_EVENT_SHUTTING_DOWN(ksmbd_shutdown_request) This event is to shutdown ksmbd server. - KSMBD_EVENT_LOGIN_REQUEST/RESPONSE(ksmbd_login_request/response) This event is to get user account info to user IPC daemon. - KSMBD_EVENT_SHARE_CONFIG_REQUEST/RESPONSE (ksmbd_share_config_request/response) This event is to get net share configuration info. - KSMBD_EVENT_TREE_CONNECT_REQUEST/RESPONSE (ksmbd_tree_connect_request/response) This event is to get session and tree connect info. - KSMBD_EVENT_TREE_DISCONNECT_REQUEST(ksmbd_tree_disconnect_request) This event is to send tree disconnect info to user IPC daemon. - KSMBD_EVENT_LOGOUT_REQUEST(ksmbd_logout_request) This event is to send logout request to user IPC daemon. - KSMBD_EVENT_RPC_REQUEST/RESPONSE(ksmbd_rpc_command) This event is to make DCE/RPC request like srvsvc, wkssvc, lsarpc, samr to be processed in userspace. - KSMBD_EVENT_SPNEGO_AUTHEN_REQUEST/RESPONSE (ksmbd_spnego_authen_request/response) This event is to make kerberos authentication to be processed in userspace.
