* ifup: fix handling when ip env is not givenAlexander Aring2016-06-151-0/+3
| | | | | | | | This patch handles the ip env to "" if no ip env is given. Otherwise we get a NULL pointer derefence. Signed-off-by: Alexander Aring <aar@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* string: Fix (v)asprintf prototypesSascha Hauer2016-04-153-7/+7
| | | | | | | | | | Our asprintf and vasprintf have different prototypes than the glibc functions. This causes trouble when we want to share barebox code with userspace code. Change the prototypes for (v)asprintf to match the glibc prototypes. Since the current (v)asprintf are convenient to use change the existing functions to b(v)asprintf.

* | net: dhcp: simplify dhcp_options_processSascha Hauer2015-12-141-9/+6
| | | | | | | | | | | | | | | | | | | | dhcp_options_handle returns the index into the dhcp_options array. This is only to be able in the caller to print a debug message when the index returned from dhcp_options_handle is out of bounds. Simplify this by printing the debug message in dhcp_options_handle and not in the caller. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | net: dhcp: unify options and paramsSascha Hauer2015-12-141-77/+57
|/ | | | | | | | | The dhcp code distinguishes between options and params. If sent to the server they are params, if received from the server they are options. Unify them all to be options. If it has a handle_param callback it's a param, if it has a handle callback it's an option. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* net: eth: Fixup OF tree with registered MAC addresses tooTrent Piepho2015-10-221-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | The eth code registers an OF tree fixup that looks for any nodes in the Linux oftree that match eth devices loaded in barebox and sets the mac-address property in those nodes. The purpose is to pass MAC addresses to the Linux kernel for drivers that expect the MAC address to be in the device tree. If barebox does not have a driver for the network device, either because it has been disabled or because one does not exist, then the OF tree will not be fixed up to include a MAC address. The eth code also has a list of MAC addresses which board code has registered, usually done when it reads the address from an EEPROM or on-chip memory. If an eth device is created later in the boot, it will look here for an address. The registered MAC address list is not used for the OF tree fix up, and this patch changes that. This way barebox can place a MAC address in the device-tree without needing a driver for the network device.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
