[ovs-dev] [PATCH v6 0/6] IPsec support for tunneling

[Qiuyu Xiao]

This patch series reintroduce IPsec support for OVS tunneling and enable
OVN to
use IPsec tunnels. GRE, VXLAN, GENEVE, and STT IPsec tunnels are
supported.
StrongSwan and LibreSwan IKE daemons are supported.

Changes from v1 to v2
---------------------
1. Merge the ovs-monitor-ipsec code to a single patch. Add LibreSwan IKE
daemon support.
2. Add ovs-monitor-ipsec to flake8 check.
3. Use openssl to extract CN from certificate so that users don't need
to
specify the CN information in the configuration interface.
4. Improve documentations as suggested.

Changes from v2 to v3
---------------------
1. Add scripts and rules to create ovs-ipsec RPM package.
2. Add Documentation/tutorials/ipsec.rst which gives a step-by-step OVS
IPsec
tutorial. Modify Documentation/howto/ipsec.rst which gives a detailed
description on OVS IPsec configuration modes.
3. Modify ovs-pki to generate x.509 version 3 certificate when do
self-sign.
4. IPsec tunnel interface needs 'local_ip' information. Modify
ovn-controller
to add 'local_ip' when IPsec is enabled.
5. Add a section on ovn/ovn-architecture.7.xml to introduce ovn IPsec.

Changes from v3 to v4
---------------------
1. Split the datapath patch to three patches (geneve, vxlan, stt).
2. Add tutorial for OVN RBAC and OVN IPsec.

Changes from v4 to v5
---------------------
1. Fix coding style issues in ovs-monitor-ipsec.
2. Improve IPsec and OVN-IPsec tutorials as suggested.
3. Change the description of setting skb_mark in documentation to
reflect the
real situation.

Changes from v5 to v6
---------------------
1. Use wildcard IP address to match localhost IP in LibreSwan. Remove
the 'local_ip' requirement when setting IPsec tunnel interface.
2. ovs-monitor-ipsec daemon accepts command line option to choose IKE
daemon, either LibreSwan or StrongSwan. The init script chooses which
IKE daemon to use. Currently, Debian init script chooses StrongSwan.
Fedora init script chooses LibreSwan.
3. Check illegal name before removing a file in
'_import_local_certs_and_key()'.
4. GRE IPsec tunnel was not activated properly when using LibreSwan. This
version fixes it.
5. The plaintext policy syntax was wrong when using LibreSwan. This version
corrects it.
6. Add comments and explanations about the 'remote_name'
check in '_is_valid_tunnel_conf()'.
7. Replace 'ike_daemon_start()' with 'ike_daemon_restart()' to start IKE
daemon.
