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.
This would not be a good idea. What happens if the name of the
interface used on the system is not "eth0"?
Also, IP packets can be routed out of any available interface,
so just because one interface (eth0) is down, doesn't mean
that the entire system is networkless.
Thanx...
ps
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;
}
