net: cosmetic: Change IPaddr_t to struct in_addr

2015-04-18T17:11:32+00:00

This patch is simply clean-up to make the IPv4 type that is used match
what Linux uses. It also attempts to move all variables that are IP
addresses use good naming instead of CamelCase. No functional change.

net: dns: fix for DNS queries sent to the wrong MAC address

2014-09-16T16:24:00+00:00

When a DNS query is sent out, the ethernet packet can get directed to
the MAC address of a server that was communicated to before.  This is
wrong when the previously stored MAC address corresponds to a different
server's IP address, i.e. when the IP address of the previous and the
current communication are different.

The error can get reproduced by running a sequence of e.g. a TFTP
download and a DNS query, where the TFTP and DNS servers reside on
individual machines.

The fix is to clear the server's MAC address that might be left from a
previous operation, and to fetch the peer's MAC address in a new ARP
lookup, before the DNS query is sent.  This is the approach taken in
other network services, like 8e52533d1095 ("net: tftpsrv: Get correct
client MAC address").

net: Refactor to separate the UDP handler from the ARP handler

2012-05-23T22:52:53+00:00

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

net: Refactor to protect access to the NetState variable

2012-05-23T22:46:21+00:00

Changes to NetState now go through an accessor function called
net_set_state()

net: cosmetic: Un-typedef IP_t

2012-05-23T22:46:00+00:00

Rename IP header related things to IP_UDP. The existing definition
of IP_t includes UDP header, so name it to accurately describe the
structure.

net/dns.c: Fix endian conversion for big-endian in dns command

2011-10-23T21:34:19+00:00

net/dns.c used endian conversion macros wrongly (shorts in reply
were put swapped into CPU, and then ntohs() was used to swap it
back, which broke on big-endian).

Fix this by using the correct linux conversion macro for reading
a unaligned short in network byte order: get_unaligned_be16()
Thanks to Mike Frysinger pointing at the best macro to use.

Tested on big and little endian qemu boards (mips and versatile)
