This patch extracts a new helper client_socket() from connect_to_fd_opts()
to create the client socket, but don't connect to the server. Then
connect_to_fd_opts() can be implemented using client_socket() and
connect_fd_to_addr(). This helper can be used in connect_to_addr()

This patch moves "post_socket_cb" and "noconnect" into connect_to_addr(),
then connect_to_fd_opts() can be implemented by getsockname() and

The opts.{type, noconnect} is at least a bit non intuitive or unnecessary.
The only use case now is in test_bpf_ip_check_defrag_ok which ends up

much better that test should have its own

Hi Barry,
Thanks for the wonderful test program.
I have also used other swap test programs as well. A lot of those
tests are harder to setup up and run.
This test is very quick and simple to run. It can test some hard to
hit corner cases for me.

Test the case when XDP disables GRO for a packet, the effect is actually

Logs from soft_offline_page and soft_offline_in_use_page have
different formats than majority of the memory failure code:
"Memory failure: 0x${pfn}: ${lower_case_message}"
Convert them to the following format:

The pmtu testing will require that the OVS module is installed,
so do that.

The current pmtu test infrastucture requires an installed copy of the
ovs-vswitchd userspace. This means that any automated or constrained
environments may not have the requisite tools to run the tests. However,
the pmtu tests don't require any special classifier processing. Indeed
they are
This will be used when setting details about the tunnel to use as
transport. There is a difference between the ODP format between tunnel():
the 'key' flag is not actually a flag field, so we don't support it in the
same way that the vswitchd userspace supports displaying it.

The current iteration of IPv6 support requires explicit fields to be set
in addition to not properly support the actual IPv6 addresses properly.
With this change, make it so that the ipv6() bare option is usable to
create wildcarded flows to match broad swaths of ipv6 traffic.

These will be used in upcoming commits to set specific attributes for
interacting with tunnels. Since set() will use the key parsing routine, we
also make sure to prepend it with an open paren, for the action parsing to
properly understand it.

Until recently, the ovs-dpctl utility was used with a limited actions set
and didn't need to have support for multiple similar actions. However,
when adding support for tunnels, it will be important to support multiple
set() actions in a single flow. When printing these actions, the existing
The OVS module can operate in conjunction with various types of
tunnel ports. These are created as either explicit tunnel vport
types, OR by creating a tunnel interface which acts as an anchor

Currently, if a user wants to run pmtu.sh and cover all the provided test

Yes, and I think we might have to revive that discussion, unfortunately.
I started thinking about this, but did not reach a conclusion. Sharing
my thoughts.
The minimum we might need to make use of guest_memfd (v1 or v2 ;) ) not
just for private memory should be:
