| | | | | | | | | | | | | | | | | | | | | | | | | | dhcp/bootp was bound to the command functionality. This patch splits the dhcp command. We are now able to use bootp without a shell. This patch adds also a check for environment variables and globalvar. So only when ENVIRONMENT_VARIABLES and GLOBALVAR is set, all received dhcp data will be stored.

| | | | | | | | | | | | | | | | | | | | | | | | In the request packet, we are supposed to copy the IP that the DHCP server provided in the offer packet so that dhcp_extended can fill the option 50. There is actually an error in barebox as the pointer to the packet currently built is used as the source instead of the pointer to the offer packet. With this patch, barebox now sends a request packet which includes the right requested IP in option 50.

| * 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>

|/ | | | | | | | | | | | | | | | | | | 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'.

* net/ifup.c: avoid setting the MAC twiceJuergen Borleis2014-04-241-1/+0

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.
