NFS: add sysfs shutdown knob

2023-06-19T19:08:12+00:00

Within each nfs_server sysfs tree, add an entry named "shutdown". Writing 1 to this file will set the cl_shutdown bit on the rpc_clnt structs associated with that mount. If cl_shutdown is set, the task scheduler immediately returns -EIO for new tasks. Signed-off-by: Benjamin Coddington Signed-off-by: Trond Myklebust

NFS: Add sysfs links to sunrpc clients for nfs_clients

2023-06-19T19:04:13+00:00

For the general and state management nfs_client under each mount, create symlinks to their respective rpc_client sysfs entries. Signed-off-by: Benjamin Coddington Signed-off-by: Trond Myklebust

SUNRPC: Plumb an API for setting transport layer security

2023-06-19T16:16:59+00:00

Add an initial set of policies along with fields for upper layers to pass the requested policy down to the transport layer. Signed-off-by: Chuck Lever Reviewed-by: Jeff Layton Signed-off-by: Trond Myklebust

SUNRPC: Add API to force the client to disconnect

2022-10-06T13:52:09+00:00

Allow the caller to force a disconnection of the RPC client so that we can clear any pending requests that are buffered in the socket. Signed-off-by: Trond Myklebust Signed-off-by: Anna Schumaker

SUNRPC create a function that probes only offline transports

2022-07-25T14:06:04+00:00

For only offline transports, attempt to check connectivity via a NULL call and, if that succeeds, call a provided session trunking detection function. Signed-off-by: Olga Kornievskaia Signed-off-by: Trond Myklebust

SUNRPC create an rpc function that allows xprt removal from rpc_clnt

2022-07-25T14:06:04+00:00

Expose a function that allows a removal of xprt from the rpc_clnt. When called from NFS that's running a trunked transport then don't decrement the active transport counter. Signed-off-by: Olga Kornievskaia Signed-off-by: Trond Myklebust

SUNRPC enable back offline transports in trunking discovery

2022-07-25T14:06:04+00:00

When we are adding a transport to a xprt_switch that's already on the list but has been marked OFFLINE, then make the state ONLINE since it's been tested now. Signed-off-by: Olga Kornievskaia Signed-off-by: Trond Myklebust

SUNRPC add function to offline remove trunkable transports

2022-07-25T14:06:04+00:00

Iterate thru available transports in the xprt_switch for all trunkable transports offline and possibly remote them as well. Signed-off-by: Olga Kornievskaia Signed-off-by: Trond Myklebust

SUNRPC: Ensure that the gssproxy client can start in a connected state

2022-05-07T18:31:15+00:00

Ensure that the gssproxy client connects to the server from the gssproxy daemon process context so that the AF_LOCAL socket connection is done using the correct path and namespaces.

Revert "SUNRPC: Ensure gss-proxy connects on setup"

2022-05-07T18:30:40+00:00

This reverts commit 892de36fd4a98fab3298d417c051d9099af5448d. The gssproxy server is unresponsive when it calls into the kernel to start the upcall service, so it will not reply to our RPC ping at all.
