2012-07-24net: Make sure the ethaddr is updated in net_init()Joe Hershberger
NetConsole may call NetSendUDPPacket before NetLoop is called. This will cause the source MAC address (NetOurEther) to be wrong. Instead of only changing it in NetLoop, move it to NetLoopInit so that it is also updated when net_init() is called (especially by nc_start()).

2012-07-10net: fix typo in arp clean upMike Frysinger
The clean up patch missed an &, so we end up passing an int rather than a pointer to the sprintf function. arp.c: In function 'ArpReceive': arp.c:197: warning: format '%p' expects type 'void *', but argument 3 has type 'int' Signed-off-by: Mike Frysinger <[email protected]>

Add new function eth_random_enetaddr() to generate a locally administered ethernet address. Signed-off-by: Michael Walle <[email protected]> Acked-by: Joe Hershberger <[email protected]>
2012-07-07net: use common rand()/srand() functionsMichael Walle
Replace rand() with the functions from lib/. The link-local network code stores its own seed, derived from the MAC address. Thus making it independent from calls to srand() in other modules. Signed-off-by: Michael Walle <[email protected]> Acked-by: Joe Hershberger <[email protected]>
2012-05-23net: Allow filtering on debug traces in the net subsystemJoe Hershberger
Add several levels of DEBUG prints so that you can limit the noise to the severety of your problem. DEBUG_LL_STATE = Link local state machine changes DEBUG_DEV_PKT = Packets or info directed to the device DEBUG_NET_PKT = Packets on info on the network at large DEBUG_INT_STATE = Internal network state changes Signed-off-by: Joe Hershberger <[email protected]>
2012-05-23net: Work-around for brain-damaged Cisco equipment with arp-proxyJoe Hershberger
Cisco's arp-proxy feature fails to ignore the link-local address range This means that a link-local device on a network with this Cisco equipment will reply to ARP requests for our device (in addition to our reply). If we happen to reply first, the requester's ARP table will be populated with our MAC address, and one packet will be sent to us... shortly following this, the requester will get an ARP reply from the Cisco equipment telling the requester to send packets their way instead of to our device from now on. This work-around detects this link-local condition and will delay replying to the ARP request for 5ms so that the first packet is sent to the Cisco equipment and all following packets are sent to our device.

2012-05-23net: Add link-local addressing supportJoe Hershberger

2012-05-23net: Separate ArpRequest() into lower-level funcJoe Hershberger
Link-local support will need to send ARP packets, but needs more fine-grained control over the contents. Split the implementation into 2 parts so link-local can share the code. Signed-off-by: Joe Hershberger <[email protected]>
2012-05-23net: Don't copy every packet that waits for an ARPJoe Hershberger
Use the NetArpTxPacket for the ARP packet, not to hold what used to be in NetTxPacket. This saves a copy and makes the code easier to understand. Signed-off-by: Joe Hershberger <[email protected]> Acked-by: Simon Glass <[email protected]>
2012-05-23net: Fix net buffer initializationJoe Hershberger

2012-05-23net: Fix unused variable compile warningJoe Hershberger
If CONFIG_BOOTP_SERVERIP is not defined, unused variable warning is reported. This was fixed upstream using a compiler feature instead of a simple reorder of the statements.

2012-05-23net: Add net_update_ether() to handle ARP and Ping repliesJoe Hershberger

2012-05-23net: Refactor to separate the UDP handler from the ARP handlerJoe Hershberger
Call a built-in dummy if none is registered... don't require protocols to register a handler (eliminating dummies) NetConsole now uses the ARP handler when waiting on arp (instead of needing a #define hack in arp.c) Clear handlers at the end of net loop Signed-off-by: Joe Hershberger <[email protected]> Acked-by: Simon Glass <[email protected]>
