2020-06-12net: move random_port() to dnsBaruch Siach1-0/+10
The random_port() routine is not used anywhere else. Make it local to dns.c to reduce code clutter, and shrink generated code a little. Signed-off-by: Baruch Siach <baruch@tkos.co.il>
2020-05-18common: Drop log.h from common headerSimon Glass1-0/+1
Move this header out of the common header. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-08-11env: Move env_set() to env.hSimon Glass1-0/+1
Move env_set() over to the new header file. Acked-by: Joe Hershberger <joe.hershberger@ni.com> Signed-off-by: Simon Glass <sjg@chromium.org>
2017-08-16env: Rename setenv() to env_set()Simon Glass1-1/+1
We are now using an env_ prefix for environment functions. Rename setenv() for consistency. Also add function comments in common.h. Suggested-by: Wolfgang Denk <wd@denx.de> Signed-off-by: Simon Glass <sjg@chromium.org>
2015-04-18net: cosmetic: Fix checkpatch.pl failures in net.cJoe Hershberger1-1/+1
Finish eliminating CamelCase from net.c and other failures Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Simon Glass <sjg@chromium.org>
2015-04-18net: cosmetic: Clean up DNS variables and functionsJoe Hershberger1-28/+25
Make a thorough pass through all variables and function names contained within dns.c and remove CamelCase and improve naming. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Simon Glass <sjg@chromium.org>
2015-04-18net: cosmetic: Cleanup internal packet buffer namesJoe Hershberger1-3/+4
This patch cleans up the names of internal packet buffer names that are used within the network stack and the functions that use them. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
2015-04-18net: cosmetic: Name ethaddr variables consistentlyJoe Hershberger1-2/+2
Use "_ethaddr" at the end of variables and drop CamelCase. Make constant values actually 'const'. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Simon Glass <sjg@chromium.org>
2015-04-18net: cosmetic: Change IPaddr_t to struct in_addrJoe Hershberger1-9/+9
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. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Simon Glass <sjg@chromium.org>
2014-09-16net: dns: fix for DNS queries sent to the wrong MAC addressGerhard Sittig1-0/+3
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").

2012-05-23net: Refactor to separate the UDP handler from the ARP handlerJoe Hershberger1-1/+1
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 <joe.hershberger@ni.com> Acked-by: Simon Glass <sjg@chromium.org>
2012-05-23net: Refactor to protect access to the NetState variableJoe Hershberger1-4/+4
Changes to NetState now go through an accessor function called net_set_state() Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
2012-05-23net: cosmetic: Un-typedef IP_tJoe Hershberger1-1/+1
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. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
2011-10-23net/dns.c: Fix endian conversion for big-endian in dns commandBernhard Kaindl1-12/+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>
2011-05-12NET: pass source IP address to packet handlersLuca Ceresoli1-1/+1
This is needed for the upcoming TFTP server implementation. This also simplifies PingHandler() and fixes rxhand_f documentation. Signed-off-by: Luca Ceresoli <luca.ceresoli@comelit.it> Cc: Wolfgang Denk <wd@denx.de> Acked-by: Detlev Zundel <dzu@denx.de>

2009-07-22Add DNS supportRobin Getz1-0/+211
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. After performing a query, > the serverip environment var is updated. > > Probably there are some cosmetic issues with the patch. Unfortunatly I > do not have the time to correct these. 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.
