Hi, everyone:
I am a newbie, if my question waste your time, I
am sorry for that.
In clnt.c file ,call_timeout function:
I suggest the code that judge whether the network
link status is down should be added, won't they?
I tested it with one Ethernet netcard.
static void
call_timeout(struct rpc_task *task)
{
struct rpc_clnt *clnt = task->tk_client;
+ struct netdev * dev;
+ if ((dev = __dev_get_by_name("eth0")) ==
+ NULL){
+ rpc_exit(task, -ENOTCONN);
+ return;
+ }
+ else{
+ if (!netif_carrier_ok(dev)){
+ rpc_exit(task, -ENOTCONN);
+ return;
+ }
+ }
if (xprt_adjust_timeout(task->tk_rqstp) == 0) {
dprintk("RPC: %4d call_timeout (minor)\n",
task->tk_pid);
goto retry;
}
dprintk("RPC: %4d call_timeout (major)\n",
task->tk_pid);
task->tk_timeouts++;
if (RPC_IS_SOFT(task)) {
printk(KERN_NOTICE "%s: server %s not responding,
timed out\n",
clnt->cl_protname, clnt->cl_server);
rpc_exit(task, -EIO);
return;
}
if (!(task->tk_flags & RPC_CALL_MAJORSEEN)) {
task->tk_flags |= RPC_CALL_MAJORSEEN;
printk(KERN_NOTICE "%s: server %s not responding,
still trying\n",
clnt->cl_protname, clnt->cl_server);
}
rpc_force_rebind(clnt);
retry:
clnt->cl_stats->rpcretrans++;
task->tk_action = call_bind;
task->tk_status = 0;
}
