URL: <http://savannah.nongnu.org/bugs/?37068> Summary: netif up/down handling is unclear Project: lwIP - A Lightweight TCP/IP stack Submitted by: goldsimon Submitted on: Fr 10 Aug 2012 06:51:25 GMT Category: None Severity: 3 - Normal Item Group: None Status: None Privacy: Public Assigned to: None Open/Closed: Open Discussion Lock: Any Planned Release: lwIP version: CVS Head _______________________________________________________ Details: We currently send and receive on netifs that are 'administratively' set down (netif_set_down()). This happens for DHCP and AutoIP (netif is only set to 'up' after successfully acquiring an IP address). I think this is somewhat unclear and should be cleaned up in a way that a netif must always be up when sending or receiving on it. The initialization phase of DHCP/AutoIP should just set the netif IP address to '0.0.0.0' and routing should ignore netifs with '0.0.0.0'. _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/bugs/?37068> _______________________________________________ Nachricht gesendet von/durch Savannah http://savannah.nongnu.org/
