I submitted this one previously - svc_tcp_recvfrom currently returns
any errors to the caller, including ECONNRESET and the like.
This is something svc_recv isn't able to deal with:
len = svsk->sk_recvfrom(rqstp);
[...]
if (len == 0 || len == -EAGAIN) {
[...]
return -EAGAIN;
}
[...]
return len;
The nfsd main loop will exit when it sees an error code other than
EAGAIN.
The following patch fixes this problem
svc_recv is not equipped to deal with error codes other than EAGAIN,
and will propagate anything else (such as ECONNRESET) up to nfsd,
causing it to exit.
