[mpls-linux-general] ldp_zebra

[Vincent J. <ja...@en...>]

Hi

I have been testing ldp_linux with success in a very simple case that is 
described in the README.
1/ the sessions was opened between LSR
2/ the advertisement messages are sent to open LSP

I have tried ldp_zebra with the same configuration. 
1/ the discovery messages are sent and the LSR detect the peers.
2/ The TCP session is not opened. 
3/ then the advertisement messages cannot be sent and therefore the LSPs 
cannot be opened.

Who had some successful tests with ldp_zebra in order to open the LSPs and to 
initiate the FECs ?

PS: I have been looking for a long time to find a segmentation fault in 
ldp_zebra.
The fix is to break the last loop of ldp_socket_udp_recvfrom :
int
ldp_socket_udp_recvfrom(ldp_socket_mgr_handle handle,
  ldp_socket_handle socket, uint8_t * buffer, int size, ldp_dest * from)
{                                                                             
              
  ...
      }
    } else {                    /* not p2p */
      LIST_LOOP(iff->ads, c, n2) {
        tmp.s_addr = 0;
        masklen2ip(c->address->prefixlen, &tmp);
 
        if ((((struct sockaddr_in *)&addr)->sin_addr.s_addr & tmp.s_addr) ==
          (c->address->u.prefix4.s_addr & tmp.s_addr)) {
          from->if_handle = (ldp_if_handle) iff;
          break;
        }
        if (n2 == (void *)0xffffffff) {
          break; // !?!?! XXX <--- FIX But n2 should be NULL. I did not
// figure out where the element is set to 0xfff...
// This fix might works only for me.
        }
 
      }
    }
 
  }
 
  return retval;
}
