NFSv4.1: Use the nfs_client's rpc timeouts for backchannel

2024-01-04T22:01:01+00:00

For backchannel requests that lookup the appropriate nfs_client, use the state-management rpc_clnt's rpc_timeout parameters for the backchannel's response. When the nfs_client cannot be found, fall back to using the xprt's default timeout parameters.

Replace HTTP links with HTTPS ones: NFS, SUNRPC, and LOCKD clients

2020-09-21T14:21:10+00:00

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

SUNRPC: Destroy the back channel when we destroy the host transport

2019-10-30T16:04:35+00:00

When we're destroying the host transport mechanism, we should ensure that we do not leak memory by failing to release any back channel slots that might still exist. Reported-by: Neil Brown Reported-by: kbuild test robot Signed-off-by: Trond Myklebust Signed-off-by: Anna Schumaker

SUNRPC: Abstract backchannel operations

2015-11-02T18:45:15+00:00

xprt_{setup,destroy}_backchannel() won't be adequate for RPC/RMDA bi-direction. In particular, receive buffers have to be pre- registered and posted in order to receive incoming backchannel requests. Add a virtual function call to allow the insertion of appropriate backchannel setup and destruction methods for each transport. In addition, freeing a backchannel request is a little different for RPC/RDMA. Introduce an rpc_xprt_op to handle the difference.
