VPP Security Groups

Introduction

Features are tracked as they are developed in the following VPP-427.

Requirements

• Support classifiers/filters on L2/bridging interfaces
• Filter on IP-addresses with address mask (IPv4 and IPv6)
• Filter on L4 port ranges
• Filter on L2 MAC addresses
• Support IPv6 with extension headers present
• Combinations of the above filters (e.g. MAC + IP)
• Filters on ingress and egress

Work list

API

add or delete classifier table:

define classify_add_del_table
{
 u32 client_index;
 u32 context;
 u8 is_add;
 u32 table_index;
 u32 nbuckets;
 u32 memory_size;
 u32 skip_n_vectors;
 u32 match_n_vectors;
 u32 next_table_index;
 u32 miss_next_index;
 u8 mask[0];
};

define classify_add_del_table_reply
{
 u32 context;
 i32 retval;
 u32 new_table_index;
 u32 skip_n_vectors;
 u32 match_n_vectors;
};

add or delete classifier session:

define classify_add_del_session
{
 u32 client_index;
 u32 context;
 u8 is_add;
 u32 table_index;
 u32 hit_next_index;
 u32 opaque_index;
 i32 advance;
 u8 match[0];
};

define classify_add_del_session_reply
{
 u32 context;
 i32 retval;
};

define classify_set_interface_ip_table
{
 u32 client_index;
 u32 context;
 u8 is_ipv6;
 u32 sw_if_index;
 u32 table_index;		/* ~0 => off */
};

define classify_set_interface_ip_table_reply
{
 u32 context;
 i32 retval;
};

define classify_set_interface_l2_tables
{
 u32 client_index;
 u32 context;
 u32 sw_if_index;
 /* 3 x ~0 => off */
 u32 ip4_table_index;
 u32 ip6_table_index;
 u32 other_table_index;
 u8 is_input;
};

define classify_set_interface_l2_tables_reply
{
 u32 context;
 i32 retval;
};

apply input ACL to an interface:

define input_acl_set_interface
{
 u32 client_index;
 u32 context;
 u32 sw_if_index;
 u32 ip4_table_index;
 u32 ip6_table_index;
 u32 l2_table_index;
 u8 is_add;
};

define input_acl_set_interface_reply
{
 u32 context;
 i32 retval;
};

apply an output ACL to an interface:

define output_acl_set_interface
{
 u32 client_index;
 u32 context;
 u32 sw_if_index;
 u32 ip4_table_index;
 u32 ip6_table_index;
 u32 l2_table_index;
 u8 is_add;
};

define output_acl_set_interface_reply
{
 u32 context;
 i32 retval;
};
