* net: dns: return error codesSascha Hauer2018-11-291-2/+4
| | | | | | | | | | | | | | The resolv() function used to return the IP address. When net_udp_new() fails we return an error code though which the callers of resolv() take as an IP address. This is wrong of course and we could return 0 in this case. Instead we return an error code and pass the resolved IP as a pointer which allows us to return proper error codes. This patch also adds error messages and error returns to the various callers of resolv() which used to just continue with a zero IP and let the user figure out what went wrong.

| * net: dhcp: fix option 54Marcin Niestroj2018-10-261-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Option 54 (Server Identifier) is something different than SIADDR (Server IP address). Currently they are used interchangeably. This causes DHCPNAK with DHCP servers that have configured different values for each field. Create new 'dhcp_serverip' field in 'struct dhcp_result', so we treat option 54 separately. This fixes DHCP requests for servers that send two different values for SIADDR and option 54 in DHCPOFFER.

* | net: make routing work after dhcp commandAntony Pavlov2018-10-161-0/+3
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the moment only ifup stuff turns netif up. After the commit f0624a701513 ('net: Do not route traffic to interfaces that are not up') the dhcp command keeps netif->ifup == false and network subsystem can't route packets.

* DHCP: fix option 54 passingYegor Yefremov2018-02-221-5/+2
| | | | | | | | | | | | | | | Though variable net_dhcp_server_ip was declared and used as a function parameter it was never assigned. That's why a DHCP request was sent without option 54 set. Some DHCP server for example dnsmasq didn't accept such a packet. As both offered IP address and server IP are stored in the global dhcp_result structure we don't need either net_dhcp_server_ip or OfferedIP variables and can use the addresses from dhcp_result directly.

* net: dhcp: reworkSascha Hauer2017-12-141-322/+210
| | | | | | | | | | | | | | | The DHCP code is a mess. It is not clear which options are sent to the server and which options are returned from the server. Also environment variables are read from and written to all over the place. This patch cleans this up. There now is struct dhcp_req_param which is used for options sent to the server and struct dhcp_result which contains the values sent from the server. The values from the server are written to the barebox variables in a single place. Also it's now possible to call the dhcp code without modifying barebox variables at all, storing the result only in the dhcp result struct. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* net: dhcp: Do not overwrite serverip if it is validSascha Hauer2017-12-011-2/+2
| | | | | | | | | | | | | Some DHCP servers provide the wrong serverip in which case it is desired to specify it manually and won't let the dhcp command overwrite it. This has previously been done by setting the serverip again to the desired value after dhcp has been executed. With this patch we do not overwrite it in the first place if it is valid already. This is necessary when the serverip is not set via /env/network/eth* but via nv.net.server. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

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

* 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.

| | | | | | | | | | | | | | | | | | | | | | | For net boot setups it is useful to submit boot params like server or bootfile over dhcp. To distinguish diffrent type of OS running on the same hardware, a custom client id can be sent in dhcp discover/request messages. E.g. the ISC dhcp server can be configured with | class "at91sam9x5ek" { | match if substring (option vendor-class-identifier,0,20) = "barebox-at91sam9x5ek"; | | filename "/tftpboot/atmel/at91sam9x5/sam9x5ek/zImage"; | if substring (option dhcp-client-identifier,0,7) = "ser2net" { | filename "/tftpboot/atmel/at91sam9x5/sam9x5ek/zImage-ser2net"; | } | option tftp-server-name "192.168.200.98"; | option option-150 192.168.200.98; | next-server 192.168.200.98; | option root-path "192.168.200.98:/opt/work/buildroot/build/sam9x5/target"; | } Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
