* convert users to %pI4Sascha Hauer2016-09-221-4/+2
| | | | | | | Convert users of ip_to_string() and print_IPaddr() to %pI4 and remove the now unused functions. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* string: Fix (v)asprintf prototypesSascha Hauer2016-04-151-2/+2
| | | | | | | | | | 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: resolv: Make argument constSascha Hauer2015-12-141-2/+2
| | | | | | resolv() is not allowed to change the hostname argument, make it const. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* dns: handle incoming packets in the separate dns_recv() functionAntony Pavlov2015-07-011-4/+9
| | | | | | | | The separation of incoming packets handling makes it much easier to run barebox dns client on top of picotcp network stack in the future. Signed-off-by: Antony Pavlov <antonynpavlov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* commands: introduce CMD_HOSTHolger Schurig2014-05-141-1/+2
| | | | | | | | ... because NET_RESOLV can be used alone to turn on the functionality of resolv(). Signed-off-by: Holger Schurig <holgerschurig@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* commands: harmonize in-barebox documentationHolger Schurig2014-05-141-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch does probably too much, but it's hard (and very cumbersome/time consuming) to break it out. 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 Schurig2014-05-141-0/+1
| | | | | | | | | | | | | | | | | | | 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 ...

* dns: fix recursive loopSascha Hauer2012-05-161-2/+9
| | | | | | | resolv() uses getenv_ip() which in turn calls resolv(). Fix this inifinite loop by not using getenv_ip directly. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* dns: use global nameserver/domainnameSascha Hauer2012-04-151-3/+3
| | | | | | | nameserver and domainname are now globally available in the 'net' device. use these variables. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | Introduce getenv_ip_dns to be able to do not do the resolv when using it in resolv for the nameserver (Do not loop). Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
* commands: remove struct command pointer from commandsSascha Hauer2012-02-271-1/+1

| | | | | | | This is not yet used, but with this the different network commands can get rid of their global data. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
