This test populates the bhash table for a given port with
MAX_THREADS * MAX_CONNECTIONS sockets, and then times how long
a bind request on the port takes.
When populating the bhash table, we create the sockets and then bind
the sockets to the same address and port (SO_REUSEADDR and SO_REUSEPORT
are set). When timing how long a bind on the port takes, we bind on a
different address without SO_REUSEPORT set. We do not set SO_REUSEPORT
because we are interested in the case where the bind request does not
go through the tb->fastreuseport path, which is fragile (eg
tb->fastreuseport path does not work if binding with a different uid).
To run the script:
Usage: ./bind_bhash.sh [-6 | -4] [-p port] [-a address]
6: use ipv6
4: use ipv4
port: Port number
address: ip address
Without any arguments, ./bind_bhash.sh defaults to ipv6 using ip address
"2001:0db8:0:f101::1" on port 443.
On my local machine, I see:
ipv4:
before - 0.002317 seconds
with bhash2 - 0.000020 seconds
ipv6:
before - 0.002431 seconds
with bhash2 - 0.000021 seconds

There are currently 3 ip tunnels that are capable of carrying
L2 traffic: gretap, vxlan and geneve.
They all are capable to inherit the TOS/TTL for the outer
IP-header from the inner frame.
Add a test that verifies that these fields are correctly inherited.
These tests failed before the following commits:
b09ab9c92e50 ("ip6_tunnel: allow to inherit from VLAN encapsulated IP")
3f8a8447fd0b ("ip6_gre: use actual protocol to select xmit")

The custom multipath hash tests use mausezahn in order to test how
changes in various packet fields affect the packet distribution across
the available nexthops.
The tool uses the libnet library for various low-level packet
construction and injection. The library started using the
"SO_BINDTODEVICE" socket option for IPv6 sockets in version 1.1.6 and
for IPv4 sockets in version 1.2.
When the option is not set, packets are not routed according to the
table associated with the VRF master device and tests fail.
Fix this by prefixing the command with "ip vrf exec", which will cause
the route lookup to occur in the VRF routing table. This makes the tests
pass regardless of the libnet library version.

When the selftest got added, sendfile() on mptcp sockets returned
-EOPNOTSUPP, so running 'mptcp_connect.sh -m sendfile' failed
immediately.
This is no longer the case, but the script fails anyway due to timeout.
Let the receiver know once the sender has sent all data, just like
with '-m mmap' mode.
v2: need to respect cfg_wait too, as pm_userspace.sh relied
on -m sendfile to keep the connection open (Mat Martineau)

This selftest is designed for testing the H.L2Encaps.Red behavior. It
instantiates a virtual network composed of several nodes: hosts and SRv6
routers. Each node is realized using a network namespace that is
properly interconnected to others through veth pairs.
The test considers SRv6 routers implementing a L2 VPN leveraged by hosts
for communicating with each other. Such routers make use of the SRv6
H.L2Encaps.Red behavior for applying SRv6 policies to L2 traffic coming
from hosts.
The correct execution of the behavior is verified through reachability
tests carried out between hosts belonging to the same VPN.

Ping sockets don't appear to make any attempt to preserve flow labels
created and set by userspace using IPV6_FLOWINFO_SEND. Instead they are
clobbered by autolabels (if enabled) or zero.
Grab the flowlabel out of the msghdr similar to how rawv6_sendmsg does
it and move the memset up so it doesn't get zeroed after.

ipv4 arp_accept has a new option '2' to create new neighbor entries
only if the src ip is in the same subnet as an address configured on
the interface that received the garp message. This selftest tests all
options in arp_accept.
ipv6 has a sysctl endpoint, accept_untracked_na, that defines the
behavior for accepting untracked neighbor advertisements. A new option
similar to that of arp_accept for learning only from the same subnet is
added to accept_untracked_na. This selftest tests this new feature.

The new script was not listed in the programs to test.
By consequence, some CIs running MPTCP selftests were not validating
these new tests. Note that MPTCP CI was validating it as it executes all
.sh scripts from 'tools/testing/selftests/net/mptcp' directory.

The mentioned test measures the transfer run-time to verify
that the user-space program is able to use the full aggregate B/W.
Even on (virtual) link-speed-bound tests, debug kernel can slow
down the transfer enough to cause sporadic test failures.
Instead of unconditionally raising the maximum allowed run-time,
tweak when the running kernel is a debug one, and use some simple/
rough heuristic to guess such scenarios.
Note: this intentionally avoids looking for /boot/config-<version> as
the latter file is not always available in our reference CI
environments.

As mentioned in the blamed commit, flood_unicast_test() works by
checking the match count on a tc filter placed on the receiving
interface.
But the second host interface (host2_if) has no interest in receiving a
packet with MAC DA de:ad:be:ef:13:37, so its RX filter drops it even
before the ingress tc filter gets to be executed. So we will incorrectly
get the message "Packet was not flooded when should", when in fact, the
packet was flooded as expected but dropped due to an unrelated reason,
at some other layer on the receiving side.
Force h2 to accept this packet by temporarily placing it in promiscuous
mode. Alternatively we could either deliver to its MAC address or use
tcpdump_start, but this has the fewest complications.
This fixes the "flooding" test from bridge_vlan_aware.sh and
bridge_vlan_unaware.sh, which calls flood_test from the lib.

Currently, this script sets up the test scenario, which is supposed to end
in an inability of the system to negotiate a link. It then waits for a bit,
and verifies that the system can diagnose why the link was not established.
The wait time for the scenario where different link speeds are forced on
the two ends of a loopback cable, was set to 4 seconds, which exactly
covered it. As of a recent mlxsw firmware update, this time gets longer,
and this test starts failing.
The time that selftests currently wait for links to be established is
currently $WAIT_TIMEOUT, or 20 seconds. It seems reasonable that if this is
the time necessary to establish and bring up a link, it should also be
enough to determine that a link cannot be established and why.
Therefore in this patch, convert the sleeps to busywaits, so that if a
failure is established sooner (as is expected), the test runs quicker. And
use $WAIT_TIMEOUT as the time to wait.

In a few MPTCP selftest tools, gcc 12 complains that the 'sock' variable
might be used uninitialized. This is a false positive because the only
code path that could lead to uninitialized access is where getaddrinfo()
fails, but the local xgetaddrinfo() wrapper exits if such a failure
occurs.
Initialize the 'sock' variable anyway to allow the tools to build with
gcc 12.

The mentioned test-case still use an hard-coded-len sleep to
wait for a relative large number of connection to be established.
On very slow VM and with debug build such timeout could be exceeded,
causing failures in our CI.
Address the issue polling for the expected condition several times,
up to an unreasonable high amount of time. On reasonably fast system
the self-tests will be faster then before, on very slow one we will
still catch the correct condition.
