2012-05-23net: Add link-local addressing supportJoe Hershberger
Code based on networking/zcip.c in busybox commit 8531d76a15890c2c535908ce888b2e2aed35b172 Signed-off-by: Joe Hershberger <[email protected]>
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: Make sure NetLoop is initialized when using NetConsoleJoe Hershberger
Fix NetConsole bug that causes first packet header to claim a source IP address of 0.0.0.0 Signed-off-by: Joe Hershberger <[email protected]>
2012-05-23net: Fix net buffer initializationJoe Hershberger
A new non-static function net_init() will initialize buffers and read from the environment. Only update from the env on each entry to NetLoop(). Signed-off-by: Joe Hershberger <[email protected]> Acked-by: Simon Glass <[email protected]>
2012-05-23net: Remove unused parameter from NetInitLoop()Joe Hershberger
Noone uses it. Signed-off-by: Joe Hershberger <[email protected]> Acked-by: Simon Glass <[email protected]>
2012-05-23net: Remove static allocation for MAC address in PingSend()Joe Hershberger
Don't force ARP clients to return the MAC address if they don't care (such as ping) Signed-off-by: Joe Hershberger <[email protected]> Acked-by: Mike Frysinger <[email protected]>
2012-05-23net: Add option CONFIG_BOOTP_MAY_FAILJoe Hershberger
This is useful if you want to look for a DHCP server, but try some other settings if not available. Signed-off-by: Joe Hershberger <[email protected]> Acked-by: Simon Glass <[email protected]>
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. Signed-off-by: Joe Hershberger <[email protected]> Acked-by: Simon Glass <[email protected]> Acked-by: Mike Frysinger <[email protected]>
2012-05-23net: Don't write the "serverip" env var if configured not toJoe Hershberger
Before this patch, bootp would not overwrite the value, but the value was still clobbered in the env Signed-off-by: Joe Hershberger <[email protected]>
2012-05-23net: Add net_update_ether() to handle ARP and Ping repliesJoe Hershberger
When the network is VLAN or SNAP, net_update_ether() will preserve the original Ethernet packet header and simply replace the src and dest MACs and the protocol Signed-off-by: Joe Hershberger <[email protected]> Acked-by: Simon Glass <[email protected]>
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]>
2012-05-23net: Refactor to protect access to the NetState variableJoe Hershberger
Changes to NetState now go through an accessor function called net_set_state() Signed-off-by: Joe Hershberger <[email protected]>
2012-05-23net: Refactor to use NetSendPacket instead of eth_send directlyJoe Hershberger
Use this entry-point consistently across the net/ code Use a static inline function to preserve code size Signed-off-by: Joe Hershberger <[email protected]> Acked-by: Simon Glass <[email protected]>
2012-05-23net: Refactor ping receive handlerJoe Hershberger
There is no need to call through the handler... inline it Signed-off-by: Joe Hershberger <[email protected]> Acked-by: Simon Glass <[email protected]> Acked-by: Mike Frysinger <[email protected]>
2012-05-23net: Move debug trace to point of actionJoe Hershberger

Eliminate pointer subtraction that recovers values computed earlier Signed-off-by: Joe Hershberger <[email protected]> Acked-by: Simon Glass <[email protected]>
2012-05-23net: Refactor packet length computationsJoe Hershberger
Save the length when it is computed instead of forgetting it and subtracting pointers to figure it out again. Signed-off-by: Joe Hershberger <[email protected]> Acked-by: Simon Glass <[email protected]> Acked-by: Mike Frysinger <[email protected]>
2012-05-23net: Refactor NetSendUDPPacket to share more codeJoe Hershberger
Share more of the code that is common between ARP vs not. Signed-off-by: Joe Hershberger <[email protected]> Acked-by: Simon Glass <[email protected]>
2012-05-23net: Refactor IP, UPD, and ICMP header writing functionsJoe Hershberger
ICMP (ping) was reimplementing IP header code... it now shares code. Signed-off-by: Joe Hershberger <[email protected]> Acked-by: Simon Glass <[email protected]> Acked-by: Mike Frysinger <[email protected]>

2012-05-23net: cosmetic: Rename CDPHandler to cdp_receiveJoe Hershberger
This is not called as a handler, so don't name it that way Signed-off-by: Joe Hershberger <[email protected]>
2012-05-23net: cosmetic: Rename "x" to "eth_proto"Joe Hershberger
x is a poor variable name Signed-off-by: Joe Hershberger <[email protected]> Acked-by: Simon Glass <[email protected]>

2012-05-23net: cosmetic: Rename parameter len to payload_lenJoe Hershberger

Separate this functionality out of the net.c behemoth Signed-off-by: Joe Hershberger <[email protected]>
2012-05-23net: Move MAC-seeded rand out of bootp.cJoe Hershberger
Make the MAC-seeded random number generator available to /net in general. MAC-seeded rand will be needed by link-local as well, so give it an interface. Signed-off-by: Joe Hershberger <[email protected]> Acked-by: Simon Glass <[email protected]>
2012-05-23net: Remove CMD_PING where there's no CMD_NETJoe Hershberger
Some boards claim to need ping, but don't support net. That makes no sense, and causes problems now that ping is in a separate file. Signed-off-by: Joe Hershberger <[email protected]> Acked-by: Simon Glass <[email protected]>
2012-05-23net: Fix remaining API interface breakageJoe Hershberger
These are all the files which use the API incorrectly but did not get built using MAKEALL -a powerpc|arm. I have no compiler for them, but the remaining issues should be far less than without this patch. Any outstanding issues are left to the maintainers of boards that use these drivers.
