selftest: fib_tests: Always cleanup before exit

2023-02-21T09:45:08+00:00

Usage of `set -e` before executing a command causes immediate exit
on failure, without cleanup up the resources allocated at setup.
This can affect the next tests that use the same resources,
leading to a chain of failures.

A simple fix is to always call cleanup function when the script exists.
This approach is already used by other existing tests.

selftests/net: Interpret UDP_GRO cmsg data as an int value

2023-02-20T08:27:07+00:00

Data passed to user-space with a (SOL_UDP, UDP_GRO) cmsg carries an
int (see udp_cmsg_recv), not a u16 value, as strace confirms:

  recvmsg(8, {msg_name=...,
              msg_iov=[{iov_base="\0\0..."..., iov_len=96000}],
              msg_iovlen=1,
              msg_control=[{cmsg_len=20,         <-- sizeof(cmsghdr) + 4
                            cmsg_level=SOL_UDP,
                            cmsg_type=0x68}],    <-- UDP_GRO
                            msg_controllen=24,
                            msg_flags=0}, 0) = 11200

Interpreting the data as an u16 value won't work on big-endian platforms.
Since it is too late to back out of this API decision [1], fix the test.

selftests: seg6: add selftest for PSP flavor in SRv6 End behavior

2023-02-16T12:18:06+00:00

This selftest is designed for testing the PSP flavor in SRv6 End 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 makes use of the SRv6 End behavior and of the PSP flavor needed
for removing the SRH from the IPv6 header at the penultimate node.

The correct execution of the behavior is verified through reachability
tests carried out between hosts.

selftests: forwarding: Add MDB dump test cases

2023-02-11T03:21:13+00:00

The kernel maintains three markers for the MDB dump:

1. The last bridge device from which the MDB was dumped.
2. The last MDB entry from which the MDB was dumped.
3. The last port-group entry that was dumped.

Add test cases for large scale MDB dump to make sure that all the
configured entries are dumped and that the markers are used correctly.

Specifically, create 2 bridges with 32 ports and add 256 MDB entries in
which all the ports are member of. Test that each bridge reports 8192
(256 * 32) permanent entries. Do that with IPv4, IPv6 and L2 MDB
entries.

On my system, MDB dump of the above is contained in about 50 netlink
messages.

Example output:

 # ./bridge_mdb.sh
 [...]
 INFO: # Large scale dump tests
 TEST: IPv4 large scale dump tests                                   [ OK ]
 TEST: IPv6 large scale dump tests                                   [ OK ]
 TEST: L2 large scale dump tests                                     [ OK ]

selftests: fib_rule_tests: Test UDP and TCP connections with DSCP rules.

2023-02-10T06:49:04+00:00

Add the fib_rule6_send and fib_rule4_send tests to verify that DSCP
values are properly taken into account when UDP or TCP sockets try to
connect().

Tests are done with nettest, which needs a new option to specify
the DS Field value of the socket being tested. This new option is
named '-Q', in reference to the similar option used by ping.
