* net/dns.c: Fix endian conversion for big-endian in dns commandBernhard Kaindl2011-10-23-12/+8
| | | | | | | | | | | | | | | | | 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) Signed-off-by: Bernhard Kaindl <bernhard.kaindl@thalesgroup.com> Cc: Pieter Voorthuijsen <pieter.voorthuijsen@prodrive.nl> Cc: Robin Getz <rgetz@blackfin.uclinux.org> Acked-by: Mike Frysinger <vapier@gentoo.org>
* NET: pass source IP address to packet handlersLuca Ceresoli2011-05-12-1/+1

On 04 Oct 2008 Pieter posted a dns implementation for U-Boot. http://www.mail-archive.com/u-boot-users@lists.sourceforge.net/msg10216.html > > DNS can be enabled by setting CFG_CMD_DNS.

So if anybody else likes DNS > support in U-Boot and has the time, feel free to patch it in the main tree. Here it is again - slightly modified & smaller: - update to 2009-06 (Pieter's patch was for U-Boot 1.2.0) - README.dns is added - syntax is changed (now takes a third option, the env var to store the result in) - add a random port() function in net.c - sort Makefile in ./net/Makefile - dns just returns unless a env var is given - run through checkpatch, and clean up style issues - remove packet from stack - cleaned up some comments - failure returns much faster (if server responds, don't wait for timeout) - use built in functions (memcpy) rather than byte copy.
