Add two tests to deslave a port from and reenslave to a bridge. This should
retain the ability of the system to forward traffic, but on an offloading
driver that is sensitive to ordering of operations, it might not.
The first test does this configuration in a way that relies on
vlan_default_pvid to assign the PVID. The second test disables that
autoconfiguration and configures PVID by hand in a separate step.

All pm_nl_ctl commands were muted. If there was an unexpected error with
one of them, this was simply not visible in the logs, making the
analysis very hard. It could also hide misuse of commands by mistake.
Now the output is only muted when we do expect to have an error, e.g.
when giving invalid arguments on purpose.

If a Netlink command for the MPTCP path-managers is not valid, it is
important to check if there are errors. If yes, they need to be reported
instead of being ignored and exiting without errors.
Now if no replies are expected, an ACK from the kernelspace is asked by
the userspace in order to always expect a reply. We can use the same
buffer that is currently always >1024 bytes. Then we can check if there
is an error (err->error), print it if any and report the error.
After this modification, it is required to mute expected errors in
mptcp_join.sh and pm_netlink.sh selftests:
- when trying to add a bad endpoint, e.g. duplicated
- when trying to set the two limits above the hard limit

Thanks to the parent commit, it is easy to change the output and add
some colours to help spotting issues.
The colours are not used if stdout is redirected or if NO_COLOR env var
is set to 1 as specified in https://no-color.org.
It is possible to force displaying the colours even if stdout is
redirected by setting this env var:

This patch modifies how the detailed results are printed, mainly to
improve what is displayed in case of issue:
- Now the test name (title) is printed earlier, when starting the test
if it is not intentionally skipped: by doing that, errors linked to
a test will be printed after having written the test name and then
avoid confusions.
- Due to the previous item, it is required to add a new line after
having printed the test name because in case of error with a command,
it is better not to have the output in the middle of the screen.
- Each check is printed on a dedicated line with aligned status (ok,
skip, fail): it is easier to spot which one has failed, simpler to
manage in the code not having to deal with alignment case by case and
helpers can be used to uniform what is done. These helpers can also be
useful later to do more actions depending on the results or change in
one place what is printed.
- Info messages have been reduced and aligned as well. And info messages
about the creation of the default test files of 1 KB are no longer
printed.
Example:
001 no JOIN
syn [ ok ]
synack [ ok ]
ack [ ok ]
Or with a skip and a failure:
001 no JOIN
syn [ ok ]
synack [fail] got 42 JOIN[s] synack expected 0
Server ns stats
(...)
Client ns stats
(...)
ack [skip]
Or with info:
104 Infinite map
Test file (size 128 KB) for client
Test file (size 128 KB) for server
file received by server has inverted byte at 169
5 corrupted pkts
syn [ ok ]
synack [ ok ]
While at it, verify_listener_events() now also print more info in case
of failure and in pm_nl_check_endpoint(), the test is marked as failed
instead of skipped if no ID has been given (internal selftest issue).

net/tls: fixes for NVMe-over-TLS
here are some small fixes to get NVMe-over-TLS up and running.
The first set are just minor modifications to have MSG_EOR handled
for TLS, but the second set implements the ->read_sock() callback
for tls_sw.
The ->read_sock() callbacks return -EIO when encountering any TLS
Alert message, but as that's the default behaviour anyway I guess
we can get away with it.

Currently, when running ZC test suite, after finishing first run of test
suite and then switching to busy-poll tests within xskxceiver, such
errors are observed:
libbpf: Kernel error message: ice: MTU is too large for linear frames and XDP prog does not support frags
1..26
libbpf: Kernel error message: Native and generic XDP can't be active at the same time
Error attaching XDP program
not ok 1 [xskxceiver.c:xsk_reattach_xdp:1568]: ERROR: 17/"File exists"
this is because test suite ends with 9k MTU and native xdp program being
loaded. Busy-poll tests start non-multi-buffer tests for generic mode.
To fix this, let us introduce bash function that will reset NIC settings
to default (e.g. 1500 MTU and no xdp progs loaded) so that test suite
can continue without interrupts. It also means that after busy-poll
tests NIC will have those default settings, whereas right now it is left
with 9k MTU and xdp prog loaded in native mode.

Add a test that will exercise maximum number of supported fragments.
This number depends on mode of the test - for SKB and DRV it will be 18
whereas for ZC this is defined by a value from NETDEV_A_DEV_XDP_ZC_MAX_SEGS
netlink attribute.

Add a test that produces lots of nasty descriptors testing the corner
cases of the descriptor validation. Some of these descriptors are
valid and some are not as indicated by the valid flag. For a
description of all the test combinations, please see the code.
To stress the API, we need to be able to generate combinations of
descriptors that make little sense. A new verbatim mode is introduced
for the packet_stream to accomplish this. In this mode, all packets in
the packet_stream are sent as is. We do not try to chop them up into
frames that are of the right size that we know are going to work as we
would normally do. The packets are just written into the Tx ring even
if we know they make no sense.

Add the first basic multi-buffer test that sends a stream of 9K
packets and validates that they are received at the other end. In
order to enable sending and receiving multi-buffer packets, code that
sets the MTU is introduced as well as modifications to the XDP
programs so that they signal that they are multi-buffer enabled.

Add the ability to send and receive packets that are larger than the
size of a umem frame, using the AF_XDP /XDP multi-buffer
support. There are three pieces of code that need to be changed to
achieve this: the Rx path, the Tx path, and the validation logic.
Both the Rx path and Tx could only deal with a single fragment per
packet. The Tx path is extended with a new function called
pkt_nb_frags() that can be used to retrieve the number of fragments a
packet will consume. We then create these many fragments in a loop and
fill the N-1 first ones to the max size limit to use the buffer space
efficiently, and the Nth one with whatever data that is left. This
goes on until we have filled in at the most BATCH_SIZE worth of
descriptors and fragments. If we detect that the next packet would
lead to BATCH_SIZE number of fragments sent being exceeded, we do not
send this packet and finish the batch. This packet is instead sent in
the next iteration of BATCH_SIZE fragments.
For Rx, we loop over all fragments we receive as usual, but for every
descriptor that we receive we call a new validation function called
is_frag_valid() to validate the consistency of this fragment. The code
then checks if the packet continues in the next frame. If so, it loops
over the next packet and performs the same validation. once we have
received the last fragment of the packet we also call the function
is_pkt_valid() to validate the packet as a whole. If we get to the end
of the batch and we are not at the end of the current packet, we back
out the partial packet and end the loop. Once we get into the receive
loop next time, we start over from the beginning of that packet. This
so the code becomes simpler at the cost of some performance.
The validation function is_frag_valid() checks that the sequence and
packet numbers are correct at the start and end of each fragment.

Register the bpf_map_sum_elem_count func for all programs, and update the
map_ptr subtest of the test_progs test to test the new functionality.
The usage is allowed as long as the pointer to the map is trusted (when
using tracing programs) or is a const pointer to map, as in the following
example:
struct {
__uint(type, BPF_MAP_TYPE_HASH);
...
} hash SEC(".maps");
...
static inline int some_bpf_prog(void)
{
struct bpf_map *map = (struct bpf_map *)&hash;
__s64 count;
count = bpf_map_sum_elem_count(map);
...
}

The current selftests infrastructure formats the results in TAP 13. This
version doesn't support subtests and only the end result of each
selftest is taken into account. It means that a single issue in a
subtest of a selftest containing multiple subtests forces the whole
selftest to be marked as failed. It also means that subtests results are
not tracked by CIs executing selftests.
MPTCP selftests run hundreds of various subtests. It is then important
to track each of them and not one result per selftest.
It is particularly interesting to do that when validating stable kernels
with the last version of the test suite: tests might fail because a
feature is not supported but the test didn't skip that part. In this
case, if subtests are not tracked, the whole selftest will be marked as
failed making the other subtests useless because their results are
ignored.
This patch formats subtests results in TAP in userspace_pm.sh selftest.
