[lwip-users] Socket receive timeout wrong

[Fabian Cenedese]

Hi

I want to receive with the socket interface which works good.
However if no partner is connected I wanted to cancel the
receive with a timeout. But it looks like lwip interprets the
time wrongly.

What I did:
#define LWIP_SO_RCVTIMEO                  1 

struct timeval tv;
tv.tv_sec = 3;  /* 3 Secs Timeout */
tv.tv_usec = 0;
setsockopt(sockfd, SOL_SOCKET, SO_RCVTIMEO, (char *)&tv,sizeof(struct timeval));

whereas struct timeval is defined as 

struct timeval {
  long tv_sec;
  long tv_usec;
};

This struct is then used for setting the timeout like this

netconn_set_recvtimeout(sock->conn, *(int*)optval);
which is just
conn->recv_timeout=...

So it will store the seconds from the timeval struct. But this same value
is used for 
sys_arch_mbox_fetch(&mbox, (void **)&conn, conn->recv_timeout)

which interprets the time as milliseconds. So a timeout of 3 seconds
suddenly becomes 3 milliseconds. If I set the timeout to 3000 then
the call returns after about 3 seconds.

Is this an error in the code or in the documentation? Is this already fixed
in the repository?

Thanks
