From b00be49bdb39ea923211bce5ef2f1a7dc3814ccf Mon Sep 17 00:00:00 2001 From: Jean-Christophe PLAGNIOL-VILLARD Date: Sun, 8 Apr 2012 11:27:21 +0200 Subject: net: dhcp: add private extention 224 to pass the oftree file via dhcp. DHCP option 224 to 254 are for private use, so use one. Export it via env dhcp_oftree_file. E.g. the ISC dhcp server can be configured with | option oftree-path code 224 = string | class "at91sam9x5ek" { | match if substring (option vendor-class-identifier,0,20) = "barebox-at91sam9x5ek"; | | filename "/tftpboot/atmel/at91sam9x5/sam9x5ek/zImage"; | option tftp-server-name "192.168.200.98"; | option root-path "192.168.200.98:/opt/work/buildroot/build/sam9x5/target"; | option oftree-path "/tftpboot/atmel/at91sam9x5/sam9x5ek/sam9g25ek/dtb"; | } Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD Signed-off-by: Sascha Hauer --- net/dhcp.c | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'net') diff --git a/net/dhcp.c b/net/dhcp.c index ad32b535e3..0116ba423e 100644 --- a/net/dhcp.c +++ b/net/dhcp.c @@ -201,6 +201,10 @@ struct dhcp_opt dhcp_options[] = { .option = 67, .handle = bootfile_vendorex_handle, .barebox_var_name = "bootfile", + }, { + .option = 224, + .handle = env_str_handle, + .barebox_var_name = "dhcp_oftree_file", }, }; @@ -702,3 +706,4 @@ BAREBOX_MAGICVAR(dhcp_client_uuid, "cliend uuid to send to the DHCP server"); BAREBOX_MAGICVAR(dhcp_client_id, "cliend id to send to the DHCP server"); BAREBOX_MAGICVAR(dhcp_user_class, "user class to send to the DHCP server"); BAREBOX_MAGICVAR(dhcp_tftp_server_name, "TFTP server Name returned from DHCP request"); +BAREBOX_MAGICVAR(dhcp_oftree_file, "OF tree returned from DHCP request (option 224)"); -- cgit v1.2.3
