Add infrastructure to support PSP tests across network namespaces
using NetDrvContEnv with netkit pairs. This enables testing PSP device
association, where a non-PSP-capable device (e.g. netkit) in a guest
namespace is associated with a real PSP device in the host namespace,
allowing the guest to perform PSP encryption/decryption through the
host's PSP hardware.
The topology is:
Host NS: psp_dev_local <---> nk_host
| |
| | (netkit pair)
| |
Remote NS: psp_dev_peer Guest NS: nk_guest
(responder) (PSP tests)
env.py:
- nk_guest_ifindex is queried after moving the device into the guest
namespace, so tests can use it directly for dev-assoc
psp.py:
- PSP device lookup supports container environments where the PSP
device is on the physical interface, not the test interface
- Association helpers handle dev-assoc/dev-disassoc with defer-based
cleanup to prevent state leaks on test assertion failures
- main() tries NetDrvContEnv with primary_rx_redirect and falls back
to NetDrvEpEnv, so existing tests continue to work without the
container environment

The server binds the queues for zero-copy after listen(). If the client
does a connect() during this time it can fail with EHOSTUNREACH on

the .ndo_queue_start() is a slow operation during which no packets
can be exchanged.
This change moves listen() after queue binding, when the test server is

GRO test is very timing-sensitive, packets may be delayed
by the network or just sent slowly. Because of this we retry
each test case up to 6 times.
This makes perfect sense for positive cases, in which we want
to see coalescing. Negative test cases, which modify headers
and expect no coalescing should have opposite treatment.
We should really try 6 times and make sure that each time
the test failed. This would, however, require that we annotate
each test to indicate whether its positive or negative.
Let's start with a simpler improvement. Do not allow
retries if we detected over-coalescing. Previously the negative
case would have to get lucky at least once in 6 tries to pass.
Now the first failure breaks the retry loop.
For background - NICs tend to ignore the contents of the TCP
timestamp option, so that test case commonly fails. In NIPA
having 6 attempts, however, was enough for some NICs to get
multiple successful runs in a row, getting the test cases
auto-classified as expected to pass, even tho the NIC does
not comply with the expectations.

These tests are just duplicates of the original devmem tests, with some
adjusted parameters such as telling ncdevmem to avoid device setup
(since it only has access to netkit, not a phys device).
Each test uses NetDrvContEnv with primary_rx_redirect=True to set up the
BPF redirect program on the primary netkit interface, then calls a
shared run_*() helper which probes for devmem support and configures
the NIC (HDS, RSS, queue lease) before driving the test. NIC state is
restored per-test via defer() callbacks registered inside the helper.

When sending from a namespace that has access to a netkit device with a
leased queue, the nk primary in the host namespace needs to redirect its
RX to the physical device. This patch adds that redirection bpf program
and teaches the harness to install it.
Add primary_rx_redirect=False parameter to NetDrvContEnv.__init__().
When enabled, _attach_primary_rx_redirect_bpf() attaches a new BPF TC
program (nk_primary_rx_redirect.bpf.c) to the primary (host-side) netkit
interface. The program redirects non-ICMPv6 IPv6 packets to the physical
NIC via bpf_redirect_neigh(), with the physical ifindex configured via
the .bss map. ICMPv6 is left on the host's netkit primary so IPv6
neighbor discovery still work locally.
Extract _find_bss_map_id() from _attach_bpf() into a reusable helper so
other BPF attachment methods can use it.

Adding netkit-based devmem tests is a straight-forward copy of devmem
test commands plus some args for the nk cases, so this patch breaks out
these command builders into helpers used by both.
Though we tried to avoid libraries to avoid increasing the barrier of
entry/complexity (see selftests/drivers/net/README.md, section "Avoid
libraries and frameworks"), factoring out these functions seemed like
the lesser of two evils in this case of using the same commands, just
with slightly different args per environment.
I experimented with just having all of the tests in the same file to
avoid having helpers in a library file, but because ksft_run() is
limited to a single call per file, and the new tests will require
different environments (NetDrvContEnv/NetDrvEpEnv), it would have been
necessary to have each test set up its own environment instead of
sharing one for the entire ksft_run() run. This came at the cost of
ballooning the test time (from under 5s to 30s on my test system), so to
strike a balance these tests were placed in separate files so they could
keep a shared environment across a single ksft_run() run shared across
all tests using the same env type (introduced in subsequent patches).
The helpers work transparently with both plain and netkit environments
by inspecting cfg for netkit-specific attributes (netns, nk_queue,
etc...).

Add a -n (skip_config) flag that causes ncdevmem to skip NIC
configuration when operating as an RX server. When -n is passed,
ncdevmem skips configuring header split, RSS, and flow steering, as well
as their teardown on exit.
This allows ksft tests to pre-configure the NIC in the host namespace
before launching ncdevmem in the guest namespace. This is needed for
netkit devmem tests where the test harness namespace has direct access
to the NIC and the ncdevmem namespace does not.

Also relax two timeouts to reduce the number of process failures
themselves
- Increase SO_RCVTIMEO to 2 seconds
- Increase process start-up stabilization to 2 seconds

There are VXLAN tests and IPsec tests, but there is no test that
combines the two protocols and exercises the tunnel-over-ipsec code
paths. Fix that by adding a traffic test with VXLAN and IPsec using
crypto offload. This is runnable on HW which supports ESP offload (so no
nsim unfortunately).
Traffic is done with iperf3 and the test validates that there are no
packet drops and iperf3 can get to at least 100 Mbps (a very
conservative value on today's crypto offload HW, as it can typically
reach multi-Gbps rates).
Ran right now, the test fails due to a recently exposed bug in xfrm,

Replace teamd daemon usage with ip link commands for team device
setup. teamd -d daemonizes and returns to the shell before port
addition completes, creating a race: the test may create the macvlan
(and check for its address on a slave) before teamd has finished
adding ports. This makes the test inherently dependent on scheduling
timing.
Using ip commands makes port addition synchronous, removing the race
and making the test deterministic.

Add a test for ethtool NFC (ntuple) flow steering rules. The test
creates an ntuple rule matching on various flow fields and verifies
that traffic is steered to the correct queue.
The test forces all traffic to queue 0 via the indirection table,
then installs an ntuple rule to steer select traffic to a specific
queue. The test then verifies the expected number of packets is received
on the queue.
This test has variants for TCP/UDP over IPv4/IPv6, with rules matching
the source IP. Additional match fields will be added in the next commit.

Add VLAN filter propagation tests through offloaded MACsec devices via
actual traffic.
The tests create MACsec tunnels with matching SAs on both endpoints,
stack VLANs on top, and verify connectivity with ping. Covered:
- Offloaded MACsec with VLAN (filters propagate to HW)
- Software MACsec with VLAN (no HW filter propagation)
- Offload on/off toggle and verifying traffic still works
On netdevsim this makes use of the VLAN filter debugfs file to actually
validate that filters are applied/removed correctly.
On real hardware the traffic should validate actual VLAN filter
propagation.

Move MACsec offload API and ethtool feature tests from
tools/testing/selftests/drivers/net/netdevsim/macsec-offload.sh to
tools/testing/selftests/drivers/net/macsec.py using the NetDrvEnv
framework so tests can run against both netdevsim (default) and real
hardware (NETIF=ethX). As some real hardware requires MACsec to use
encryption, add that to the tests.
Netdevsim-specific limit checks (max SecY, max RX SC) were moved into
separate test cases to avoid failures on real hardware.

Add extensive selftests for netkit queue leasing, using io_uring zero
copy test binary inside of a netns with netkit. This checks that memory
providers can be bound against virtual queues in a netkit within a
netns that are leasing from a physical netdev in the default netns.
Also add various test cases around corner cases for the queue creation
itself as well as queue info dumping and teardown in case of netkit in
device pair and single mode.
