From: Chuck Lever <chuck.lever@xxxxxxxxxx> An NFS mount request can sometimes hang when TLS is requested. This series attempts to address that. I've checked on a couple of things since v1. - Why doesn't the Linux kernel SunRPC client already poll just after connecting? Typically the SunRPC client does not expect an RPC Reply (ie, any ingress traffic) until it has sent an RPC Call first. RPC-with-TLS has changed that scenario a bit. - Is this an issue for other in-kernel TLS consumers? It is. But the only other in-kernel TLS consumer at the moment is NVMe over TCP, and it already polls after a successful connection, for other reasons. Changes since v1: - Include Mike's R-b and T-b tags in 1/2 - Clean up dead code noticed while testing Chuck Lever (2): SUNRPC: Prevent hang on NFS mount with xprtsec=[m]tls SUNRPC: Remove dead code from xs_tcp_tls_setup_socket() net/sunrpc/xprtsock.c | 16 +++++----------- 1 file changed, 5 insertions(+), 11 deletions(-) -- 2.49.0
