* net/bootp.c: Fix GCC 4.6 warningAnatolij Gustschin2011-11-23-1/+2
| | | | | | | | Fix: bootp.c: In function 'BootpCopyNetParams': bootp.c:108:11: warning: unused variable 'tmp_ip' [-Wunused-variable] Signed-off-by: Anatolij Gustschin <agust@denx.de>
* net/net.c: Fix GCC 4.6 build warningWolfgang Denk2011-11-07-3/+1
| | | | | | | | | Fix: net.c: In function 'CDPHandler': net.c:1083:8: warning: variable 'applid' set but not used [-Wunused-but-set-variable] Signed-off-by: Wolfgang Denk <wd@denx.de>
* net: Export auto_load, use it in rarpSimon Glass2011-10-27-49/+33
| | | | | | | | | | | The rarp code includes another instance of the auto_load logic, so call what is now net_auto_load() instead. This also fixes an incorrect call to TftpStart() which was never seen since apparently no boards enable rarp.

* net: Change for loop to memset()Simon Glass2011-10-27-6/+2
| | | | | | This is intended purely as a code size reduction. Signed-off-by: Simon Glass <sjg@chromium.org>
* net: Add more #ifdefs for tftpput to reduce code sizeSimon Glass2011-10-27-1/+10
| | | | | | | If CONFIG_CMD_TFTPPUT is not enabled, we want minimal code size impact on the tftp code. This introduces a few more #ifdefs. Signed-off-by: Simon Glass <sjg@chromium.org>
* net: Make net_transfer() a static functionSimon Glass2011-10-27-1/+1
| | | | | | | This should be a static function so it can be inlined. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Mike Frysinger <vapier@gentoo.org>
* net: Hide more code behind CONFIG_CMD_TFTPPUTSimon Glass2011-10-27-2/+12
| | | | | | | | This commit reduces code size a little by making the ICMP handler only available to tftpput. This is reasonable since it is the only user at present (ping just uses the normal handler). Signed-off-by: Simon Glass <sjg@chromium.org>
* net: tftpput: implement tftp logicSimon Glass2011-10-26-21/+117
| | | | | | | This adds logic to tftp.c to implement the tftp 'put' command, and updates the README. Signed-off-by: Simon Glass <sjg@chromium.org>
* net: tftpput: Support selecting get/put for tftpSimon Glass2011-10-26-4/+3
| | | | | | TftpStart should support starting either a get or a put. Signed-off-by: Simon Glass <sjg@chromium.org>
* net: tftpput: Factor out start, restart and next block functionsSimon Glass2011-10-26-26/+51
| | | | | | This code is required for tftpput, so move it into separate functions. Signed-off-by: Simon Glass <sjg@chromium.org>
* net: tftpput: move common code into separate functionsSimon Glass2011-10-26-30/+38
| | | | | | | We want to show block markers on completion of get and put, so move this common code into separate functions. Signed-off-by: Simon Glass <sjg@chromium.org>
* net: tftpput: Rename TFTP to TFTPGETSimon Glass2011-10-26-10/+8
| | | | | | | | This is a better name for this protocol. Also remove the typedef to keep checkpatch happy, and move zeroing of NetBootFileXferSize a little earlier since TFTPPUT will need to change this. Signed-off-by: Simon Glass <sjg@chromium.org>
* net: tftpput: Add support for receiving ICMP packetsSimon Glass2011-10-26-3/+24
| | | | | | | | | | ICMP packets can tell you when there is no server at the other end. It is useful for tftp to figure this out, so that a quick error can be displayed, rather than pointlessly retrying. This adds an ICMP packet handler to the net interface. Signed-off-by: Simon Glass <sjg@chromium.org>
* net: tftpput: Move ICMP code into its own functionSimon Glass2011-10-26-43/+58
| | | | | | | NetReceive() is a very long function with a lot of indent. Before adding code to the ICMP bit, split it out. Signed-off-by: Simon Glass <sjg@chromium.org>
* 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: bootp: add PXE/RFC 4578 DHCP options supportJason Hobbs2011-10-17-0/+40
| | | | | | | | | | These options are required to be present in RFC 4578 compliant DHCP requests. They give more information to DHCP servers to allow serving different DHCP responses to different systems based on client architecture, client capabilities, UUID, or vendor. Signed-off-by: Jason Hobbs <jason.hobbs@calxeda.com>
* net: drop !NET_MULTI codeMike Frysinger2011-10-05-74/+11
| | | | | | | | | | | This is long over due. All but two net drivers have been converted, but those have now been dropped. The only thing left to do is actually delete all references to NET_MULTI and code that is compiled when that is not defined. So here we scrub the core code. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* net: drop !NET_MULTI ns7520 driverMike Frysinger2011-10-05-4/+0
| | | | | | | This driver was never converted to NET_MULTI, and no board uses it. So punt it and be done. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* net: turn name len check into an assertMike Frysinger2011-09-21-6/+1
| | | | | | | | | The new sanity check introduces a printf warning for some systems: eth.c:233: warning: format '%zu' expects type 'size_t', but argument 3 has type 'int' Rather than tweak the format string, use the new assert() helper instead. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* net/bootp.c: fix tftp load if autoload environment var isn't setPeter Korsgaard2011-09-19-1/+1
| | | | | | | | | | | | | Commit 093498669 (Put common autoload code into auto_load() function) broke handling of autoload environment variable not being set. The bootp/dhcp code will just keep on requesting IP address forever and never start TFTP download. Fix it by moving TftpStart() outside the conditional like it was before.

* net/eth.c: throw BUG for eth_get_dev_by_name(NULL)Helmut Raiger2011-09-09-0/+2
| | | | | | | | eth_get_dev_by_name() is not safe to use for devname being NULL as it uses strcmp. This patch makes it fail with a BUG(). Signed-off-by: Helmut Raiger <helmut.raiger@hale.at> Acked-by: Mike Frysinger <vapier@gentoo.org>
* Correct call to eth_write_hwaddr()Simon Glass2011-09-05-1/+1
| | | | | | | | | | | | | | This fixes "Warning: failed to set MAC address" on platforms which rely on an 'ethaddr' environment variable to set the MAC address.

* Add Ethernet hardware MAC address framework to usbnetSimon Glass2011-08-08-25/+39
| | | | | | | | | | | | Built-in Ethernet adapters support setting the mac address by means of a ethaddr environment variable for each interface (ethaddr, eth1addr, eth2addr). This adds similar support to the USB network side, using the names usbethaddr, usbeth1addr, etc. They are kept separate since we don't want a USB device taking the MAC address of a built-in device or vice versa.

* net/net.c: Update ipaddr if the environment has changedEnric Balletbo i Serra2011-06-01-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At least on ARM the ipaddr is only set in board_init_r function. The problem is if ipaddr is not defined in environment importing another environment defined don't update the ipaddr value. For example, suppose we've a default environment without net variables defined and we want to import an uEnv.txt environment from SD-card like this: ipaddr=192.168.2.240 netmask=255.255.255.0 gatewayip=192.168.2.1 serverip=192.168.2.114 Then if you try boot from NFS results in: Importing environment from mmc ... Running uenvcmd ... smc911x: detected LAN9221 controller smc911x: phy initialized smc911x: MAC ac:de:48:00:00:00 *** ERROR: `ipaddr' not set The ipaddr at this point is NULL beacause is only set at board_init_r function.
