With this change we will try to detect all the netdev-afxdp
dependencies and enable AF_XDP support by default if they are
present at the build time.
Configuration script behaves in a following way:
- ./configure --enable-afxdp
Will check for AF_XDP dependencies and fail if they are
not available.
- ./configure --disable-afxdp
Disables checking for AF_XDP. Build will not support
AF_XDP even if all dependencies are installed.
- Just ./configure or ./configure --enable-afxdp=auto
Will check for AF_XDP dependencies. Will print a warning
if they are not available, but will continue without AF_XDP
support. If dependencies are available in a system, this
option is equal to --enable-afxdp.
'--disable-afxdp' added to the debian and fedora package builds
to keep predictable behavior.

Update OVS CLI and relevant documentation to use DPDK 21.11.2.
DPDK 21.11.2 contains fixes for the CVEs listed below:
CVE-2022-28199 [1]
CVE-2022-2132 [2]
A bug was introduced in DPDK 21.11.1 by the commit
01e3dee29c02 ("vhost: fix unsafe vring addresses modifications").
This bug can cause a deadlock when vIOMMU is enabled and NUMA
reallocation of the virtqueues happen.
A fix [3] has been posted and pushed to the DPDK 21.11 branch.
If a user wishes to avoid the issue then it is recommended to use
DPDK 21.11.0 until the release of DPDK 21.11.3.
It should be noted that DPDK 21.11.0 does not benefit from the
numerous bug and CVE fixes addressed since its release.
If a user wishes to benefit from these fixes it is recommended to
use DPDK 21.11.2.

supported process of ftp traffic. However, previous version

Implementation on Windows:
Currently, IPv4 conntrack was supported on the windows platform.
In this patch we have implemented ipv6 conntrack functions according
to the current logic of the IPv4 conntrack. This implementation has
included TcpV6(nat and normal scenario), UdpV6(nat and normal scenario),
IcmpV6 conntrack of echo request/reply packet and
FtpV6(nat and normal scenario).
Testing Topology:
On the Windows VM runs on the ESXi host, two hyper-v ports attached
to the ovs bridge; one hyper-v port worked as client and the
other port worked as server.
Testing Case:
1. TcpV6
a) Tcp request/reply conntrack for normal scenario.
In this scenario, 20::1 as client, 20::2 as server, it will generate
following conntrack entry:
(Origin(src=20::1, src_port=1555, dst=20::2, dst_port=1556),
reply(src=20::2,src_port=1556,dst=20::1,dst_port=1555),protocol=tcp)
b) Tcp request/reply conntrack for nat scenario.
In this scenario, 20::1 as client, 20::10 as floating ip, 21::3 as server,
it will generate following conntrack entry:
(Origin(src=20::1, src_port=1555, dst=20::10, dst_port=1556),
reply(src=21::3, src_port=1556, dst=20::1, dst_port= 1555),protocol=tcp)
2. UdpV6
a) Udp request/reply conntrack for normal scenario.
(Origin(src=20::1, src_port=1555, dst=20::2, dst_port=1556),
reply(src=20::2,src_port=1556,dst=20::1,dst_port=1555),protocol=udp)
b) Udp request/reply conntrack for nat scenario.
(Origin(src=20::1, src_port=1555, dst=20::10, dst_port=1556),
reply(src=21::3, src_port=1556, dst=20::1, dst_port= 1555),protocol=udp)
3. IcmpV6:
a) Icmpv6 request/reply conntrack for normal scenario.
Currently Icmpv6 only support to construct conntrack for
echo request/reply packet, take (20::1 -> 20::2) for example,
it will generate following conntrack entry:
(origin(src = 20::1, dst=20::2), reply(src=20::2, dst=20::1), protocol=icmp)
b) Icmp request/reply conntrack for dnat scenario,
for example (20::1->20::10->21::3), 20::1 is
client, 20::10 is floating ip, 21::3 is server ip.
It will generate flow like below:
(origin(src=20::1, dst=20::10), reply(src=21::3, dst=20::1), protocol=icmp)
4. FtpV6
a) Ftp request/reply conntrack for normal scenario.
In this scenario, take 20::1 as client, 20::2 as server, it will generate
two conntrack entries:
Ftp active mode
(Origin(src=20::1, src_port=1555, dst=20::2, dst_port=21),
reply(src=20::2, src_port=21, dst=20::1, dst_port=1555), protocol=tcp)
(Origin(src=20::2, src_port=20, dst=20::1, dst_port=1556),
reply(src=20::1, src_port=1556, dst=20::2, dst_port=20), protocol=tcp)
Ftp passive mode
(Origin(src=20::1, src_port=1555, dst=20::2, dst_port=21),
reply(src=20::2,src_port=21,dst=20::1,dst_port=1555),protocol=tcp)
(Origin(src=20::1, src_port=1556, dst=20::2, dst_port=1557),
reply(src=20::2,src_port=1557, dst=20::1, dst_port=1556) protocol=tcp)
b) Ftp request/reply conntrack for nat scenario.
Ftp passive mode,
In this secnario, 20::1 as client, 20::10 as floating ip, 21::3 as server
ip. It will generate following flow:
(Origin(src=20::1, src_port=1555, dst=20::10, dst_port=21),
reply(src=21::3, src_port=21, dst=20::1, dst_port= 1555),protocol=tcp)
(Origin(src=20::1, src_port=1556, dst=20::10, dst_port=1557),
reply(src=21::3, src_port=1557, dst=20::1, dst_port= 1556),protocol=tcp)
5. Regression test for IpV4 in Antrea project (about 60 test case)
Future work:
1) IcmpV6 redirect packet conntrack.
2) IpV6 fragment support on Udp.
3) Support napt for IPv6.
4) FtpV6 active mode for nat.

In the first step OVS Windows will support IPv6 tunnel(Geneve IPv6 tunnel).
Implementation on Windows
-------------------------
1. For the IPv6 tunnel support, OvsIPTunnelKey will replace original
OvsIPv4TunnelKey in the related flow context handing.
2. The related src and dst address will be changed to SOCKADDR_INET type from UINT32.
3. For the IPv6 tunnel, one node running OVS-Windows could encapsulate IPv4/IPv6
Packets via IPV6 Geneve Tunnel, and the node could also encapsulate IPv4/IPv6 packet
Via IPv4 Geneve tunnel.
4. Related IPHelper data structure will be adapted to support IPv6 Tunnel. In the IPHelper
part the related Windows API(such as GetUnicastIpAddressTable/GetBestRoute2/GetIpNetEntry2/
ResolveIpNetEntry2) and Windows data structure(MIB_IPFORWARD_ROW2/MIB_IPNET_ROW2/IP_ADDRESS_PREFIX)
Have already supported both IPv4 and IPV6. Now OVS Windows has been adjusted some functions
And data structured to support IPV6 tunnel also.
5. OVS_TUNNEL_KEY_ATTR_IPV6_SRC and OVS_TUNNEL_KEY_ATTR_IPV6_DST filed will be supported in
OVS-Windows kernel for IPV6 tunnel.
Testing done.
-------------------------
Related topo, 1 Windows VM(Win2019) and 2 Ubuntu 16.04 server. Both VMs
Are running on one ESX host.
1. Setup one IPV6 Geneve Tunnel between 1 Windows VM and 1 Ubuntu server.
Windows VM, vif0( 6000::2/40.1.1.10) vif1(5000::2)—— Ubuntu VM Eth2(5000::9), name space ns1
with interface ns1_link_peer(6000::9/40.1.1.2)
Related tunnnel,
ovs-vsctl.exe add-port br-int bms-tun0 -- set interface bms-tun0 type=Geneve options:csum=true
options:key=flow options:local_ip="5000::2" options:remote_ip=flow
In this topo, traffic from Vif0(Win) to ns1_link_peer(Ubuntu) will be gone through the Geneve tunnel
(5000::2—>5000::9) for both IPv4 traffic(40.1.1.10-->40.1.1.2) and IPv6 traffic(6000::2—>6000::9)
2. Setup one IPV4 Geneve Tunnel between Windows VM and 1 Ubuntu server.
Windows VM, vif0( 6000::2/40.1.1.10) vif1(50.1.1.11)—— Ubuntu, Eth2(50.1.1.9), name space ns1
with interface ns1_link_peer(6000::19/40.1.1.9)
Related tunnnel,
ovs-vsctl.exe -- set Interface bms-tun0 type=geneve options:csum=true options:key=flow
options:local_ip="50.1.1.11" options:remote_ip=flow
In this topo, traffic from Vif0(Win) to ns1_link_peer(Ubuntu) will be gone through the Geneve Tunnel
(50.1.1.11—>50.1.1.9) for both IPv4 traffic(40.1.1.10-->40.1.1.9) and IPv6 traffic(6000::2—>6000::19).

This change removes the default values for EAL args socket-mem and
socket-limit. As DPDK supports dynamic memory allocation, there is no
need to allocate a certain amount of memory on start-up, nor limit the
amount of memory available, if not requested.
Currently, socket-mem has a default value of 1024 when it is not
configured by the user, and socket-limit takes on the value of
socket-mem, 1024, by default. With this change, socket-mem is not
configured by default, meaning that socket-limit is not either.
Neither, either or both options can be set.

The default DPDK library used before this patch in case pkg-config
fails to find libdpdk is only valid for make based DPDK builds.
Hence remove them.
As a consequence, now this error message [1] is thrown when pkg-config
cannot find libdpdk instead of proceeding to check for a faulty
pkg-config and reporting incorrect error message [2].
Also, update the documentation to export PKG_CONFIG_PATH since on some
systems, the default install path for DPDK libraries is not present in
the default search path of pkg-config.
Ex: for Fedora 32 default pkg-config search path:
/usr/lib64/pkgconfig:/usr/share/pkgconfig
while by default Meson installs DPDK libraries at:
/usr/local/lib64/pkgconfig
[1] Package libdpdk was not found in the pkg-config search path.
Perhaps you should add the directory containing `libdpdk.pc'
to the PKG_CONFIG_PATH environment variable
Package 'libdpdk', required by 'virtual:world', not found
[2] checking for DPDK... no
checking for faulty pkg-config version... yes
configure: error: Please upgrade pkg-config
Also, update the build documentation for AVX512 optimization.

Currently, the AF_XDP socket (XSK) related memory are allocated by main
thread in the main thread's NUMA domain. With the patch that detects
netdev-linux's NUMA node id, the PMD thread of AF_XDP port will be run on
the AF_XDP netdev's NUMA domain. If the net device's NUMA domain
is different from the main thread's NUMA domain, we will have two
cross-NUMA memory accesses (netdev <-> memory, memory <-> CPU).
This patch addresses the aforementioned issue by allocating
the memory in the net device's NUMA domain.

The patch detects the numa node id from the name of the netdev,
by reading the '/sys/class/net/<devname>/device/numa_node'.
If not available, ex: virtual device, or any error happens,
return numa id 0. Currently only the afxdp netdev type uses it,
other linux netdev types are disabled due to no use case.

This reverts commit 9e334d91b3ea95e2b96f7b3edcb2ba9c3353288a.

Since Python 2 support was removed in 1ca0323e7c29 ("Require Python 3 and
remove support for Python 2."), python3-six is not needed anymore.
Moreover python3-six is not available on RHEL/CentOS7 without using EPEL
and so this patch is needed in order to release OVS 2.13 on RHEL7.
