* convert users to %pI4Sascha Hauer2016-09-221-3/+3
| | | | | | | 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 Hauer2016-04-151-3/+3
| | | | | | | | | | 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: make unmodified variable constSascha Hauer2015-12-141-3/+3
| | | | | | | 'str' in dhcp_set_string_options is never modified, so make it const. With this we no longer have to cast away the const returned from getenv. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* 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: dhcp: Split dhcp funcionality & add dhcp commandWadim Egorov2015-06-051-101/+64
| | | | | | | | | | | | | 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.

* dhcp: fix request packet's requested IP optionEric Bénard2015-01-291-1/+1
| | | | | | | | | | | | 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.

* commands: harmonize in-barebox documentationHolger Schurig2014-05-141-22/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 ...

* 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>
