As previously discussed with David Ahern, here is a refactored and improved
version of the IOAM self-test. It is now more complete and more robust. Now,
all tests are divided into three categories: OUTPUT (evaluates the IOAM
processing by the sender), INPUT (evaluates the IOAM processing by the receiver)
and GLOBAL (evaluates wider use cases that do not fall into the other two
categories). Both OUTPUT and INPUT tests only use a two-node topology (alpha and
beta), while GLOBAL tests use the entire three-node topology (alpha, beta,
gamma). Each test is documented inside its own handler in the (bash) script.

Implement a GRO testsuite that expects Linux kernel GRO behavior.
All tests pass with the kernel software GRO stack. Run against a device
with hardware GRO to verify that it matches the software stack.
gro.c generates packets and sends them out through a packet socket. The
receiver in gro.c (run separately) receives the packets on a packet
socket, filters them by destination ports using BPF and checks the
packet geometry to see whether GRO was applied.
gro.sh provides a wrapper to run the gro.c in NIC loopback mode.
It is not included in continuous testing because it modifies network
configuration around a physical NIC: gro.sh sets the NIC in loopback
mode, creates macvlan devices on the physical device in separate
namespaces, and sends traffic generated by gro.c between the two
namespaces to observe coalescing behavior.
GRO coalescing is time sensitive.
Some tests may prove flaky on some hardware.
Note that this test suite tests for software GRO unless hardware GRO is
enabled (ethtool -K $DEV rx-gro-hw on).
To test, run ./gro.sh.
The wrapper will output success or failed test names, and generate
log.txt and stderr.
Sample log.txt result:
...
pure data packet of same size: Test succeeded
large data packets followed by a smaller one: Test succeeded
small data packets followed by a larger one: Test succeeded
...
Sample stderr result:
...
carrier ready

Expected {200 }, Total 1 packets
Received {200 }, Total 1 packets.

This patch adds OOB support for AF_UNIX sockets.
The semantics is same as TCP.
The last byte of a message with the OOB flag is
treated as the OOB byte. The byte is separated into
a skb and a pointer to the skb is stored in unix_sock.
The pointer is used to enforce OOB semantics.

raw gso min size - 1 (expected to fail)

After commit 7c6d2ecbda ("net: be more gentle about silly

check in virtio_net_hdr_to_skb().
So when a packet which is smaller then the gso_size,
GSO for this packet will not be set, the packet will be

This test evaluates the IOAM insertion for IPv6 by checking the IOAM data
integrity on the receiver.
The topology is formed by 3 nodes: Alpha (sender), Beta (router in-between)
and Gamma (receiver). An IOAM domain is configured from Alpha to Gamma only,
which means not on the reverse path. When Gamma is the destination, Alpha
adds an IOAM option (Pre-allocated Trace) inside a Hop-by-hop and fills the
trace with its own IOAM data. Beta and Gamma also fill the trace. The IOAM
data integrity is checked on Gamma, by comparing with the pre-defined IOAM
configuration (see below).

Note: When Gamma is the destination, Alpha adds an IOAM Pre-allocated Trace
option inside a Hop-by-hop, where 164 bytes are pre-allocated for the
trace, with 123 as the IOAM-Namespace and with 0xfff00200 as the trace
type (= all available options at this time). As a result, and based on
IOAM configurations here, only both Alpha and Beta should be capable of
inserting their IOAM data while Gamma won't have enough space and will
set the overflow bit.

Without this modification, we were often displaying this error messages:
FAIL: Could not even run loopback test
But $ret could have been set to a non 0 value in many different cases:
- net.mptcp.enabled=0 is not working as expected
- setsockopt(..., TCP_ULP, "mptcp", ...) is allowed
- ping between each netns are failing
- tests between ns1 as a receiver and ns>1 are failing
- other tests not involving ns1 as a receiver are failing
So not only for the loopback test.
Now a clearer message, including the time it took to run all tests, is

veth.sh is a shell script that uses /bin/sh; some distro (Ubuntu for

following error:
# ./veth.sh: 21: local: -r: bad variable name
# ./veth.sh: 21: local: -r: bad variable name
This happens because dash doesn't support the option "-r" with local.
Moreover, in case of missing bpf object, the script is exiting -1, that
is an illegal number for dash:
exit: Illegal number: -1

Oliver reported a use case where deleting a VRF device can hang
waiting for the refcnt to drop to 0. The root cause is that the dst
is allocated against the VRF device but cached on the loopback
device.
The use case (added to the selftests) has an implicit VRF crossing
due to the ordering of the FIB rules (lookup local is before the
l3mdev rule, but the problem occurs even if the FIB rules are
re-ordered with local after l3mdev because the VRF table does not
have a default route to terminate the lookup). The end result is
is that the FIB lookup returns the loopback device as the nexthop,
but the ingress device is in a VRF. The mismatch causes the dst
alloc against the VRF device but then cached on the loopback.
The fix is to bring the trick used for IPv6 (see ip6_rt_get_dev_rcu):
pick the dst alloc device based the fib lookup result but with checks
that the result has a nexthop device (e.g., not an unreachable or
prohibit entry).

In the commit referenced below, a check was added to devlink_lib that
asserts the existence of a devlink device referenced by $DEVLINK_DEV.
Unfortunately, several netdevsim tests point DEVLINK_DEV at a device that
does not exist at the time that devlink_lib is sourced. Thus these tests
spuriously fail.
Fix this by introducing an override. By setting DEVLINK_DEV to an empty
string, the user declares their intention to handle DEVLINK_DEV management
on their own.
In all netdevsim tests that use devlink_lib and set DEVLINK_DEV, set
instead an empty DEVLINK_DEV just before sourcing devlink_lib, and set it
to the correct value right afterwards.

The mirror_gre_scale test creates as many ERSPAN sessions as the underlying
chip supports, and tests that they all work. In order to determine that it
issues a stream of ICMP packets and checks if they are mirrored as
expected.
However, the mausezahn invocation missed the -6 flag to identify the use of
IPv6 protocol, and was sending ICMP messages over IPv6, as opposed to
ICMP6. It also didn't pass an explicit source IP address, which apparently
worked at some point in the past, but does not anymore.
To fix these issues, extend the function mirror_test() in mirror_lib by
detecting the IPv6 protocol addresses, and using a different ICMP scheme.

The FDB roaming test installs a destination MAC address on the wrong
interface of an FDB database and tests whether the mirroring fails, because
packets are sent to the wrong port. The test by mistake installs the FDB
entry as local. This worked previously, because drivers were notified of
local FDB entries in the same way as of static entries. However that has
been fixed in the commit 6ab4c3117a ("net: bridge: don't notify switchdev
for local FDB addresses"), and local entries are not notified anymore. As a
result, the HW is not reconfigured for the FDB roam, and mirroring keeps
working, failing the test.
To fix the issue, mark the FDB entry as static.

'mptcp_connect' already has a timeout for poll() but in some cases, it
is not enough.
With "timeout" tool, we will force the command to fail if it doesn't
finish on time. Thanks to that, the script will continue and display
details about the current state before marking the test as failed.
Displaying this state is very important to be able to understand the
issue. Best to have our CI reporting the issue than just "the test
hanged".
Note that in mptcp_connect.sh, we were using a long timeout to validate
the fact we cannot create a socket if a sysctl is set. We don't need
this timeout.
In diag.sh, we want to send signals to mptcp_connect instances that have
been started in the netns. But we cannot send this signal to 'timeout'
otherwise that will stop the timeout and messages telling us SIGUSR1 has
been received will be printed. Instead of trying to find the right PID
and storing them in an array, we can simply use the output of
'ip netns pids' which is all the PIDs we want to send signal to.

IDs are supposed to be between 0 and 255.
In pm_nl_ctl, for both the 'add' and 'get' instruction, the ID is casted
in a u_int8_t. So if we give 256, we will delete ID 0. Obviously, the
goal is not to delete this ID by giving 256.
We could modify pm_nl_ctl and stop if the ID is negative or higher than
255 but probably better not to increase the number of lines for such
things in this tool which is only used in selftests. Instead, we use it
within the limits.
This modification also means that we will no longer add a new ID for the
2nd entry. That's why we removed an expected entry from the dump and
introduced with
commit dc8eb10e95 ("selftests: mptcp: add testcases for setting the address ID").
So now we delete ID 9 like before and we add entries for IDs 10 to 255
that are deleted just after.
Note that this could be seen as a fix but it was not really an issue so
far: we were simply playing with ID 0/1 once again. With the following
commit ("selftests: mptcp: add addr argument for del_addr"), it will be
different because ID 0 is going to required an address. We don't want
errors when trying to delete ID 0 without the address argument.

When mirroring to a gretap in hardware the device expects to be
programmed with the egress port and all the encapsulating headers. This
requires the driver to resolve the path the packet will take in the
software data path and program the device accordingly.
If the path cannot be resolved (in this case because of an unresolved
neighbor), then mirror installation fails until the path is resolved.
This results in a race that causes the test to sometimes fail.
Fix this by setting the neighbor's state to permanent, so that it is
always valid.

Since the mptcp_join script is becoming too big, this patch splits it
into several smaller chunks, each of them has been defined in a function
as a individual test group for several related testcases.
Using bash getopts function to parse command line arguments, and invoke
each function to do the individual test group.
Here are all the arguments:
-f subflows_tests
-s signal_address_tests
-l link_failure_tests
-t add_addr_timeout_tests
-r remove_tests
-a add_tests
-6 ipv6_tests
-4 v4mapped_tests
-b backup_tests
-p add_addr_ports_tests
-c syncookies_tests

routing.
Expect the current kernel behavior at the time of this patch. That is:
* 0/8 and 240/4 may be used as unicast, with the exceptions of 0.0.0.0
and 255.255.255.255;
* the lowest address in a subnet may only be used as a broadcast address;
* 127/8 may not be used as unicast (the route_localnet option, which is
disabled by default, still leaves it treated slightly specially);
* 224/4 may not be used as unicast.

After creating PMTU exceptions, the route from the device A to R1 will be

exceptions were properly cleaned up by the kernel, this device deletion
will succeed. Otherwise, the unregistration of the device will stall, and

tweewide: Fix most Shebang lines
When multiple subflows are active, we can receive a
window update on subflow with no write space available.
MPTCP will try to push frames on such subflow and will
fail. Pending frames will be pushed only after receiving
a window update on a subflow with some wspace available.
Overall the above could lead to suboptimal aggregate
bandwidth usage.
Instead, we should try to push pending frames as soon as
the subflow reaches both conditions mentioned above.

The test program udpgso_bench_rx always invokes the poll()
syscall with a timeout of 10ms. If a larger timeout is specified
via the command line, udpgso_bench_rx is supposed to do multiple
poll() calls till the timeout is expired or an event is received.
Currently the poll() loop errors out after the first invocation with
no events, and may causes self-tests failure alike:
failed
GRO with custom segment size ./udpgso_bench_rx: poll: 0x0 expected 0x1
This change addresses the issue allowing the poll() loop to consume
all the configured timeout.

This patch added the test case for retransmitting ADD_ADDR when timeout
occurs. It set NS1's add_addr_timeout to 1 second, and drop NS2's ADD_ADDR
echo packets.
Here we need to slow down the transfer process of all data to let the
ADD_ADDR suboptions can be retransmitted three times. So we added a new
parameter "speed" for do_transfer, it can be set with fast or slow.
We also added three new optional parameters for run_tests, and dropped
run_remove_tests function.
Since we added the netfilter rules in this test case, we need to update
the "config" file.

* Unicast MPLS,
* IPv4 only,
* IPv4 in multiproto mode (that is, IPv4 and IPv6),
* IPv6.
Each mode is tested with both an IPv4 and an IPv6 underlay.
v2:
* Add build dependencies in config file (Willem de Bruijn).
* The MPLS test now uses its own IP addresses. This minimises
the amount of cleanup between tests and simplifies the script.
* Verify that iproute2 supports bareudp tunnels before running the
script (and other minor usability improvements).
