#!/bin/bash # SPDX-License-Identifier: GPL-2.0+ # # Author: Justin Iurman <[email protected]> # # This script evaluates IOAM for IPv6 by checking local IOAM configurations and # IOAM data inside packets. There are three categories of tests: LOCAL, OUTPUT, # and INPUT. The former (LOCAL) checks all IOAM related configurations locally # without sending packets. OUTPUT tests verify the processing of an IOAM # encapsulating node, while INPUT tests verify the processing of an IOAM transit # node. Both OUTPUT and INPUT tests send packets. Each test is documented inside # its own handler. # # The topology used for OUTPUT and INPUT tests is made of three nodes: # - Alpha (the IOAM encapsulating node) # - Beta (the IOAM transit node) # - Gamma (the receiver) ** # # An IOAM domain is configured from Alpha to Beta, but not on the reverse path. # Alpha adds an IOAM option (Pre-allocated Trace) inside a Hop-by-hop. # # ** Gamma is required because ioam6_parser.c uses a packet socket and we need # to see IOAM data inserted by the very last node (Beta), which would happen # _after_ we get a copy of the packet on Beta. Note that using an # IPv6 raw socket with IPV6_RECVHOPOPTS on Beta would not be enough: we also # need to access the IPv6 header to check some fields (e.g., source and # destination addresses), which is not possible in that case. As a # consequence, we need Gamma as a receiver to run ioam6_parser.c which uses a # packet socket. # # # +-----------------------+ +-----------------------+ # | | | | # | Alpha netns | | Gamma netns | # | | | | # | +-------------------+ | | +-------------------+ | # | | veth0 | | | | veth0 | | # | | 2001:db8:1::2/64 | | | | 2001:db8:2::2/64 | | # | +-------------------+ | | +-------------------+ | # | . | | . | # +-----------.-----------+ +-----------.-----------+ # . . # . . # . . # +-----------.----------------------------------.-----------+ # | . . | # | +-------------------+ +-------------------+ | # | | veth0 | | veth1 | | # | | 2001:db8:1::1/64 | ............ | 2001:db8:2::1/64 | | # | +-------------------+ +-------------------+ | # | | # | Beta netns | # | | # +----------------------------------------------------------+ # # # # +==========================================================+ # | Alpha - IOAM configuration | # +=====================+====================================+ # | Node ID | 1 | # +---------------------+------------------------------------+ # | Node Wide ID | 11111111 | # +---------------------+------------------------------------+ # | Ingress ID | 0xffff (default value) | # +---------------------+------------------------------------+ # | Ingress Wide ID | 0xffffffff (default value) | # +---------------------+------------------------------------+ # | Egress ID | 101 | # +---------------------+------------------------------------+ # | Egress Wide ID | 101101 | # +---------------------+------------------------------------+ # | Namespace Data | 0xdeadbeef | # +---------------------+------------------------------------+ # | Namespace Wide Data | 0xcafec0caf00dc0de | # +---------------------+------------------------------------+ # | Schema ID | 777 | # +---------------------+------------------------------------+ # | Schema Data | something that will be 4n-aligned | # +---------------------+------------------------------------+ # # # +==========================================================+ # | Beta - IOAM configuration | # +=====================+====================================+ # | Node ID | 2 | # +---------------------+------------------------------------+ # | Node Wide ID | 22222222 | # +---------------------+------------------------------------+ # | Ingress ID | 201 | # +---------------------+------------------------------------+ # | Ingress Wide ID | 201201 | # +---------------------+------------------------------------+ # | Egress ID | 202 | # +---------------------+------------------------------------+ # | Egress Wide ID | 202202 | # +---------------------+------------------------------------+ # | Namespace Data | 0xffffffff (default value) | # +---------------------+------------------------------------+ # | Namespace Wide Data | 0xffffffffffffffff (default value) | # +---------------------+------------------------------------+ # | Schema ID | 0xffffff (= None) | # +---------------------+------------------------------------+ # | Schema Data | | # +---------------------+------------------------------------+ source lib.sh ################################################################################ # # # WARNING: Be careful if you modify the block below - it MUST be kept # # synchronized with configurations inside ioam6_parser.c and always # # reflect the same. # # # ################################################################################ ALPHA=( 1 # ID 11111111 # Wide ID 0xffff # Ingress ID (default value) 0xffffffff # Ingress Wide ID (default value) 101 # Egress ID 101101 # Egress Wide ID 0xdeadbeef # Namespace Data 0xcafec0caf00dc0de # Namespace Wide Data 777 # Schema ID "something that will be 4n-aligned" # Schema Data ) BETA=( 2 # ID 22222222 # Wide ID 201 # Ingress ID 201201 # Ingress Wide ID 202 # Egress ID 202202 # Egress Wide ID 0xffffffff # Namespace Data (empty value) 0xffffffffffffffff # Namespace Wide Data (empty value) 0xffffff # Schema ID (empty value) "" # Schema Data (empty value) ) TESTS_LOCAL=" local_sysctl_ioam_id local_sysctl_ioam_id_wide local_sysctl_ioam_intf_id local_sysctl_ioam_intf_id_wide local_sysctl_ioam_intf_enabled local_ioam_namespace local_ioam_schema local_ioam_schema_namespace local_route_ns local_route_tunsrc local_route_tundst local_route_trace_type local_route_trace_size local_route_trace_type_bits local_route_trace_size_values " TESTS_OUTPUT=" output_undef_ns output_no_room output_no_room_oss output_bits output_sizes output_full_supp_trace " TESTS_INPUT=" input_undef_ns input_no_room input_no_room_oss input_disabled input_oflag input_bits input_sizes input_full_supp_trace " ################################################################################ # # # LIBRARY # # # ################################################################################ check_kernel_compatibility() { setup_ns ioam_tmp_node &>/dev/null local ret=$?
