* netconsole: rename console to "netconsole"Sascha Hauer2014-07-111-0/+1
| | | | | | So that it can be used without guessing the name first. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | If the devicetree has an alias for the ethernet device, then use it. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * net: Allow to use multiple network interfaces at onceSascha Hauer2014-05-152-37/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In barebox network packets always go out at the current ethernet device and are expected to be received from the current interface. This has some side effects. When for example an NFS is mounted when one interface is active and the interface is changed afterwards the NFS packets leave the new interface, but the NFS server won't be reachable there. Instead of changing the whole network traffic to the current ethernet interface we now initialize a network connection with the current network interface, but then the connection will continue to use that interface even when the current interface is changed.

What is does is this: * each command has one short description, e.g. "list MUX configuration" * made sure the short descriptions start lowercase * each command has one usage. That string contains just the options, e.g. "[-npn]". It's not part of the long help text. * that is, it doesn't say "[OPTIONS]" anymore, every usable option is listed by character in this (short) option string (the long description is in the long help text, as before) * help texts have been reworked, to make them - sometimes smaller - sometimes describe the options better - more often present themselves in a nicer format * all long help texts are now created with BUSYBOX_CMD_HELP_ macros, no more 'static const __maybe_unused char cmd_foobar_help[]' * made sure the long help texts starts uppercase * because cmdtp->name and cmdtp->opts together provide the new usage, all "Usage: foobar" texts have been removed from the long help texts * BUSYBOX_CMD_HELP_TEXT() provides the trailing newline by itself, this is nicer in the source code * BUSYBOX_CMD_HELP_OPT() provides the trailing newline by itself * made sure no line gets longer than 77 characters * delibertely renamed cmdtp->usage, so that we can get compile-time errors (e.g. in out-of-tree modules that use register_command() * the 'help' command can now always emit the usage, even without compiled long help texts * 'help -v' gives a list of commands with their short description, this is similar like the old "help" command before my patchset * 'help -a' gives out help of all commands Signed-off-by: Holger Schurig <holgerschurig@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | commands: group 'help' outputHolger Schurig2014-05-145-0/+5
|/ | | | | | | | | | | | | | | | | | | The old output of "help" was just producing a long list, that usually scrolled of the screen (even on a X11 terminal). This list is more compact, and also sorted by groups. The old output format (plus grouping) is now available with 'help -v'. Example: Information commands: ?, devinfo, help, iomem, meminfo, version Boot commands: boot, bootm, go, loadb, loads, loadx, loady, saves, uimage ...

* net/ifup.c: avoid setting the MAC twiceJuergen Borleis2014-04-241-1/+0
| | | | | | | | | | The command always sets the MAC address of the interface in the code path. For the static network configuration case it sets it again, due to the environment variable keyword ("ethaddr") is listed again in the table. Remove this keyword from the table, because the MAC is already set. Signed-off-by: Juergen Borleis <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* net/ifup.c: don't fail silentlyJuergen Borleis2014-04-241-2/+6
| | | | | | | | | | | Since commit a162dfe50345d3461010759f8a0e79f7e388c140 the ifup command is implemented in C and runs up to two external scripts. If one of these scripts return with an error code, the command terminates silently. This can confuse a user because there is no hint about the reason why it fails. Add error messages to avoid this case. Signed-off-by: Juergen Borleis <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | net: Set mac-address propertySascha Hauer2013-06-051-0/+54
|/ | | | | | | | | | Linux normally has no idea how to retrieve MAC Addresses, but instead expects the MAC address in the devicetree. This patch adds the MAC address to the devicetree for Linux if we find a valid one in barebox. This mechanism is limited of course to devices barebox has a driver for and which are probed themselves from the devicetree. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* net: Add of_register_ethaddrSascha Hauer2013-05-211-12/+56
| | | | | | | | | | | | We already have a possibility to register a MAC address provider based on a ethernet device id. This adds a similar functionality for devices probed from devicetree. Code can register itself to be a MAC address provider for a certain devicetree node. This helps on i.MX to let the IIM unit provide a MAC address for the FEC.

* net: dhcp: Fix tftp servername handlingSascha Hauer2013-05-141-3/+6
| | | | | | | | | | | | | When the dhcp code discovered the tftp-server-name option it immediately tries to resolve the name. This can't succeed since the we are somewhere in the dhcp processing and the nameserver may not even be known. Fix this by resolving the name when dhcp is completed. While at it, do this in a way that net_set_serverip is only called when resolv() returns something useful. Otherwise we may end up overwriting a previously configured serverip which came from the bootp bp_siaddr field. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
