From 853c494efd7d4a3183918df69c21ceefc5ed7578 Mon Sep 17 00:00:00 2001 From: Eric Andersen Date: Thu, 23 Jan 2003 05:59:32 +0000 Subject: [PATCH] A patch from John F. Kelly to add in a utility for configuring vlan under linux, derived from Ben Greear's VLAN "vconfig" tool. --- include/applets.h | 3 + include/usage.h | 11 +++ networking/Config.in | 6 ++ networking/Makefile.in | 1 + networking/vconfig.c | 166 +++++++++++++++++++++++++++++++++++++++++ 5 files changed, 187 insertions(+) create mode 100644 networking/vconfig.c diff --git a/include/applets.h b/include/applets.h index 504f86a17..9e88f5044 100644 --- a/include/applets.h +++ b/include/applets.h @@ -598,6 +598,9 @@ #ifdef CONFIG_UUENCODE APPLET(uuencode, uuencode_main, _BB_DIR_USR_BIN, _BB_SUID_NEVER) #endif +#ifdef CONFIG_VCONFIG + APPLET(vconfig, vconfig_main, _BB_DIR_SBIN, _BB_SUID_NEVER) +#endif #ifdef CONFIG_VI APPLET(vi, vi_main, _BB_DIR_BIN, _BB_SUID_NEVER) #endif diff --git a/include/usage.h b/include/usage.h index 077306bdf..d2fb19372 100644 --- a/include/usage.h +++ b/include/usage.h @@ -2369,6 +2369,17 @@ "$ uudecode busybox busybox > busybox.uu\n" \ "$\n" +#define vconfig_trivial_usage \ + "COMMAND [OPTIONS] ..." + +#define vconfig_full_usage \ +"Usage: add [interface-name] [vlan_id] \n" \ +" rem [vlan-name] \n" \ +" set_flag [interface-name] [flag-num] [0 | 1] \n" \ +" set_egress_map [vlan-name] [skb_priority] [vlan_qos] \n" \ +" set_ingress_map [vlan-name] [skb_priority] [vlan_qos] \n" \ +" set_name_type [name-type] \n" + #define vi_trivial_usage \ "[OPTION] [FILE]..." #define vi_full_usage \ diff --git a/networking/Config.in b/networking/Config.in index ebefd600d..22676c085 100644 --- a/networking/Config.in +++ b/networking/Config.in @@ -376,6 +376,12 @@ config CONFIG_FEATURE_TRACEROUTE_SO_DEBUG help Please submit a patch to add help text for this item. +config CONFIG_VCONFIG + bool "vconfig" + default n + help + Creates, removes, and configures VLAN interfaces + config CONFIG_WGET bool "wget" default n diff --git a/networking/Makefile.in b/networking/Makefile.in index 144091abc..12fc8ddbd 100644 --- a/networking/Makefile.in +++ b/networking/Makefile.in @@ -47,6 +47,7 @@ NETWORKING-$(CONFIG_TELNET) += telnet.o NETWORKING-$(CONFIG_TELNETD) += telnetd.o NETWORKING-$(CONFIG_TFTP) += tftp.o NETWORKING-$(CONFIG_TRACEROUTE) += traceroute.o +NETWORKING-$(CONFIG_VCONFIG) += vconfig.o NETWORKING-$(CONFIG_WGET) += wget.o libraries-y+=$(NETWORKING_DIR)$(NETWORKING_AR) diff --git a/networking/vconfig.c b/networking/vconfig.c new file mode 100644 index 000000000..0ad759e69 --- /dev/null +++ b/networking/vconfig.c @@ -0,0 +1,166 @@ +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include "busybox.h" + + + +int vconfig_main(int argc, char** argv) { + int fd; + struct vlan_ioctl_args if_request; + + char* cmd = NULL; + char* if_name = NULL; + unsigned int vid = 0; + unsigned int skb_priority; + unsigned short vlan_qos; + unsigned int nm_type = VLAN_NAME_TYPE_PLUS_VID; + + char* conf_file_name = "/proc/net/vlan/config"; + + memset(&if_request, 0, sizeof(struct vlan_ioctl_args)); + + if ((argc < 3) || (argc > 5)) { + error_msg_and_die("Expecting argc to be 3-5, inclusive.
