511e8db540 selftests: forwarding: Add test for custom multipath hash
Test that when the hash policy is set to custom, traffic is distributed
only according to the outer fields set in the fib_multipath_hash_fields
sysctl.

Each time set a different field and make sure traffic is only
distributed when the field is changed in the packet stream.

The test only verifies the behavior with non-encapsulated IPv4 and IPv6
packets. Subsequent patches will add tests for IPv4/IPv6 overlays on top
of IPv4/IPv6 underlay networks.

Example output:

 # ./custom_multipath_hash.sh
 TEST: ping                                                          [ OK ]

77a88274dc kbuild: replace LANG=C with LC_ALL=C
LANG gives a weak default to each LC_* in case it is not explicitly
defined. LC_ALL, if set, overrides all other LC_* variables.

  LANG  <  LC_CTYPE, LC_COLLATE, LC_MONETARY, LC_NUMERIC, ...  <  LC_ALL

This is why documentation such as [1] suggests to set LC_ALL in build
scripts to get the deterministic result.

LANG=C is not strong enough to override LC_* that may be set by end
users.

b881d089c7 selftests/net: bump timeout to 5 minutes
We found that with the latest mainline kernel (5.12.0-051200rc8) on
some KVM instances / bare-metal systems, the following tests will take
longer than the kselftest framework default timeout (45 seconds) to
run and thus got terminated with TIMEOUT error:
* xfrm_policy.sh - took about 2m20s
* pmtu.sh - took about 3m5s
* udpgso_bench.sh - took about 60s

Bump the timeout setting to 5 minutes to allow them have a chance to
finish.

1233898ab7 selftests: mlxsw: Fix mausezahn invocation in ERSPAN scale test
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.
Fix __mirror_gre_test() in the selftest itself to pass a source IP address.

c8d0260cdd selftests: net: mirror_gre_vlan_bridge_1q: Make an FDB entry static
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.

5888a61cb4 selftests: mptcp: launch mptcp_connect with timeout
'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.

6254ad4088 selftests: mptcp: avoid calling pm_nl_ctl with bad IDs
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.

8da6229b95 selftests: mptcp: timeout testcases for multi addresses
This patch added the timeout testcases for multi addresses, valid and
invalid.

These testcases need to transmit 8 ADD_ADDRs, so add a new speed level
'least' to set 10 to mptcp_connect to slow down the transmitting process.
The original speed level 'slow' still uses 50.

2e580a63b5 selftests: mptcp: add cfg_do_w for cfg_remove
In some testcases, we need to slow down the transmitting process. This
patch added a new argument named cfg_do_w for cfg_remove to allow the
caller to pass an argument to cfg_remove.

In do_rnd_write, use this cfg_do_w to control the transmitting speed.

5aa3c334a4 selftests: forwarding: vxlan_bridge_1d: Fix vxlan ecn decapsulate value
The ECN bit defines ECT(1) = 1, ECT(0) = 2. So inner 0x02 + outer 0x01
should be inner ECT(0) + outer ECT(1). Based on the description of
__INET_ECN_decapsulate, the final decapsulate value should be
ECT(1). So fix the test expect value to 0x01.

Before the fix:
TEST: VXLAN: ECN decap: 01/02->0x02                                 [FAIL]
        Expected to capture 10 packets, got 0.

After the fix:
TEST: VXLAN: ECN decap: 01/02->0x01                                 [ OK ]

edcbf5137f selftests: forwarding: Fix race condition in mirror installation
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.

c09bfd9a5d selftests: tc: Add generic mpls matching support for tc-flower
Add tests in tc_flower.sh for generic matching on MPLS Label Stack
Entries. The label, tc, bos and ttl fields are tested for the first
and second labels. For each field, the minimal and maximal values are
tested (the former at depth 1 and the later at depth 2).
There are also tests for matching the presence of a label stack entry
at a given depth.

In order to reduce the amount of code, all "lse" subcommands are tested
in match_mpls_lse_test(). Action "continue" is used, so that test
packets are evaluated by all filters. Then, we can verify if each
filter matched the expected number of packets.

Some versions of tc-flower produced invalid json output when dumping
MPLS filters with depth > 1. Skip the test if tc isn't recent enough.

the following command:

   $tcflags dst_ip 192.0.2.2 ip_ttl 63 action drop

doesn't drop all IPv4 packets that match the configured TTL / destination
address. In particular, if "fragment offset" or "more fragments" have non
zero value in the IPv4 header, setting of FLOW_DISSECTOR_KEY_IP is simply
ignored. Fix this dissecting IPv4 TTL and TOS before fragment info; while
at it, add a selftest for tc flower's match on 'ip_ttl' that verifies the
correct behavior.

Now we have:

  # ns4 MPTCP -> ns2 (dead:beef:1::2:10035) MPTCP	(duration  1242ms) [ OK ]

addresses can be assigned as unicast addresses on links and used in
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.

Adds new 2 new tests to the PTMU script: pmtu_ipv4/6_route_change.

These tests explicitly test for a recently discovered problem in the
IPv6 routing framework where PMTU exceptions were not properly released
when replacing a route via "ip route change ...".

After creating PMTU exceptions, the route from the device A to R1 will be
replaced with a new route, then device A will be deleted. If the PMTU
exceptions were properly cleaned up by the kernel, this device deletion
will succeed. Otherwise, the unregistration of the device will stall, and
messages such as the following will be logged in dmesg:

This is because the $lret in check_xfrm() is not a local variable.
Therefore when a test failed in check_exceptions(), the non-zero $lret

With this fix, the final return value will be 1. Make it easier for

219d04992b mptcp: push pending frames when subflow has free space
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.

We can finally enable self-tests with asymmetric links,
as the above makes them finally pass.

syscall with a timeout of 10ms. If a larger timeout is specified

Currently the poll() loop errors out after the first invocation with
no events, and may causes self-tests failure alike:

8d014eaa92 selftests: mptcp: add ADD_ADDR timeout test case
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).

287d354059 selftests: mptcp: depends on built-in IPv6
Recently, CONFIG_MPTCP_IPV6 no longer selects CONFIG_IPV6. As a
consequence, if CONFIG_MPTCP_IPV6=y is added to the kconfig, it will no
longer ensure CONFIG_IPV6=y. If it is not enabled, CONFIG_MPTCP_IPV6
will stay disabled and selftests will fail.

We also need CONFIG_IPV6 to be built-in. For more details, please see
commit 0ed37ac586 ("mptcp: depends on IPV6 but not as a module").

Note that 'make kselftest-merge' will take all 'config' files found in
'tools/testsing/selftests'. Because some of them already set
CONFIG_IPV6=y, MPTCP selftests were still passing. But they will fail if
MPTCP selftests are launched manually after having executed this command
to prepare the kernel config:

  ./scripts/kconfig/merge_config.sh -m .config \
      ./tools/testing/selftests/net/mptcp/config

1a01727676 selftests: Add VRF route leaking tests
The objective of the tests is to check that ICMP errors generated while
crossing between VRFs are properly routed back to the source host.

The first ttl test sends a ping with a ttl of 1 from h1 to h2 and parses the
output of the command to check that a ttl expired error is received.

The second ttl test runs traceroute from h1 to h2 and parses the output to
check for a hop on r1.

The mtu test sends a ping with a payload of 1450 from h1 to h2, through
r1 which has an interface with a mtu of 1400 and parses the output of the
command to check that a fragmentation needed error is received.

[ The IPv6 MTU test still fails with the symmetric routing setup. It
  appears to be caused by source address selection picking ::1.  Fixing
  this is beyond the scope of this series. ]

Provide an example script which can be used as a skeleton for offloading
TCAM rules in the Ocelot switches.

Not all actions are demoed, mostly because of difficulty to automate
this from a single board.

For example, policing. We can set up an iperf3 UDP server and client and
measure throughput at destination. But at least with DSA setups, network
namespacing the individual ports is not possible because all switch
ports are handled by the same DSA master. And we cannot assume that the
target platform (an embedded board) has 2 other non-switch generator
ports, we need to work with the generator ports as switch ports (this is
the reason why mausezahn is used, and not IP traffic like ping). When
somebody has an idea how to test policing, that can be added to this
test.

6e0972e0c5 selftests: forwarding: devlink_lib: Split devlink_..._set() into save & set
Changing pool type from static to dynamic causes reinterpretation of
threshold values. They therefore need to be saved before pool type is
changed, then the pool type can be changed, and then the new values need
to be set up.

For that reason, set cannot subsume save, because it would be saving the
wrong thing, with possibly a nonsensical value, and restore would then fail
to restore the nonsensical value.

Thus extract a _save() from each of the relevant _set()'s. This way it is
possible to save everything up front, then to tweak it, and then restore in
the required order.

dd72b0fede selftests: mptcp: add remove addr and subflow test cases
This patch added the remove addr and subflow test cases and two new
functions.

The first function run_remove_tests calls do_transfer with two new
arguments, rm_nr_ns1 and rm_nr_ns2, for the numbers of addresses should be
removed during the transfer process in namespace 1 and namespace 2.

If both these two arguments are 0, we do the join test cases with
"mptcp_connect -j" command. Otherwise, do the remove test cases with
"mptcp_connect -r" command.

The second function chk_rm_nr checks the RM_ADDR related mibs's counters.

The output of the test cases looks like this:

11 remove single subflow           syn[ ok ] - synack[ ok ] - ack[ ok ]
                                   rm [ ok ] - sf    [ ok ]
12 remove multiple subflows        syn[ ok ] - synack[ ok ] - ack[ ok ]
                                   rm [ ok ] - sf    [ ok ]
13 remove single address           syn[ ok ] - synack[ ok ] - ack[ ok ]
                                   add[ ok ] - echo  [ ok ]
                                   rm [ ok ] - sf    [ ok ]
14 remove subflow and signal       syn[ ok ] - synack[ ok ] - ack[ ok ]
                                   add[ ok ] - echo  [ ok ]
                                   rm [ ok ] - sf    [ ok ]

                                   add[ ok ] - echo  [ ok ]

Otherwise the remove address and subflow test cases don't work.

bc2652b7ae selftest/net/xfrm: Add test for ipsec tunnel
It's an exhaustive testing for ipsec: covering all encryption/
authentication/compression algorithms. The tests are run in two
network namespaces, connected by veth interfaces. To make exhaustive
testing less time-consuming, the tests are run in parallel tasks,
specified by parameter to the selftest.

As the patches set adds support for xfrm in compatible tasks, there are
tests to check structures that differ in size between 64-bit and 32-bit
applications.
The selftest doesn't use libnl so that it can be easily compiled as
compatible application and don't require compatible .so.

Here is a diagram of the selftest:

Two minor conflicts:

   moving another local variable and removing it's
   initial assignment.

2) drivers/net/dsa/microchip/ksz9477.c, overlapping changes.
   One pretty prints the port mode differently, whilst another
   changes the driver to try and obtain the port mode from

a listener in the VXLAN driver to the nexthop notification chain. Its
purpose is to cleanup FDB entries that use a nexthop that is being
deleted.

Test that such FDB entries are removed when the nexthop group that they
use is deleted. Test that entries are not deleted when a single nexthop
in the group is deleted.

e548465818 selftests/mptcp: Better delay & reordering configuration
The delay was intended to be configured to "simulate" a high(er) BDP
link. As such, it needs to be set as part of the loss-configuration and
not as part of the netem reordering configuration.

The reordering-config also requires a delay but that delay is the
reordering-extend. So, a good approach is to set the reordering-extend
as a function of the configured latency. E.g., 25% of the overall
latency.

To speed up the selftests, we limit the delay to 50ms maximum to avoid
having the selftests run for too long.

Finally, the intention of tc_reorder was that when it is unset, the test
picks a random configuration. However, currently it is always initialized
and thus the random config won't be picked up.

Netfilter updates for net-next

The following patchset contains Netfilter updates for net-next:

1) Rewrite inner header IPv6 in ICMPv6 messages in ip6t_NPT,
   from Michael Zhou.

2) do_ip_vs_set_ctl() dereferences uninitialized value,
   from Peilin Ye.

3) Support for userdata in tables, from Jose M. Guisado.

4) Do not increment ct error and invalid stats at the same time,
   from Florian Westphal.

5) Remove ct ignore stats, also from Florian.

6) Add ct stats for clash resolution, from Florian Westphal.

7) Bump reference counter bump on ct clash resolution only,
   this is safe because bucket lock is held, again from Florian.

8) Use ip_is_fragment() in xt_HMARK, from YueHaibing.

9) Add wildcard support for nft_socket, from Balazs Scheidler.

10) Remove superfluous IPVS dependency on iptables, from
    Yaroslav Bolyukin.

11) Remove unused definition in ebt_stp, from Wang Hai.

12) Replace CONFIG_NFT_CHAIN_NAT_{IPV4,IPV6} by CONFIG_NFT_NAT
    in selftests/net, from Fabian Frederick.

13) Add userdata support for nft_object, from Jose M. Guisado.

72653ae530 selftests: net: tcp_mmap: Use huge pages in send path
There are significant gains using huge pages when
available, as shown in [1].

This patch adds mmap_large_buffer() and uses it
in client side (tx path of this reference tool)

Following patch will use the feature for server side.

0d89419319 selftests: net: tcp_mmap: use madvise(MADV_DONTNEED)
When TCP_ZEROCOPY_RECEIVE operation has been added,
I made the mistake of automatically un-mapping prior
content before mapping new pages.

This has the unfortunate effect of adding potentially long
MMU operations (like TLB flushes) while socket lock is held.

Using madvise(MADV_DONTNEED) right after pages has been used
has two benefits :

1) This releases pages sooner, allowing pages to be recycled
if they were part of a page pool in a NIC driver.

2) No more long unmap operations while preventing immediate
processing of incoming packets.

The cost of the added system call is small enough.

Arjun will submit a kernel patch allowing to opt out from
the unmap attempt in tcp_zerocopy_receive()

bcf7ddb018 selftests: disable rp_filter for icmp_redirect.sh
h1 is initially configured to reach h2 via r1 rather than the
more direct path through r2. If rp_filter is set and inherited
for r2, forwarding fails since the source address of h1 is
reachable from eth0 vs the packet coming to it via r1 and eth1.
Since rp_filter setting affects the test, explicitly reset it.

6bdb6211a6 mptcp: more stable diag self-tests
During diag self-tests we introduce long wait in the mptcp test
program to give the script enough time to access the sockets
dump.

Such wait is introduced after shutting down one sockets end. Since
commit 43b54c6ee3 ("mptcp: Use full MPTCP-level disconnect state
machine") if both sides shutdown the socket is correctly transitioned
into CLOSED status.

As a side effect some sockets are not dumped via the diag interface,
because the socket state (CLOSED) does not match the default filter, and
this cause self-tests instability.

Address the issue moving the above mentioned wait before shutting
down the socket.

16f6458f24 selftests/net: relax cpu affinity requirement in msg_zerocopy test
The msg_zerocopy test pins the sender and receiver threads to separate
cores to reduce variance between runs.

But it hardcodes the cores and skips core 0, so it fails on machines
with the selected cores offline, or simply fewer cores.

The test mainly gives code coverage in automated runs. The throughput
of zerocopy ('-z') and non-zerocopy runs is logged for manual
inspection.

Continue even when sched_setaffinity fails. Just log to warn anyone
interpreting the data.

10fef9ca6a selftests: ethtool: Fix test when only two speeds are supported
The test case check_highest_speed_is_chosen() configures $h1 to
advertise a subset of its supported speeds and checks that $h2 chooses
the highest speed from the subset.

To find the common advertised speeds between $h1 and $h2,
common_speeds_get() is called.

Currently, the first speed returned from common_speeds_get() is removed
claiming "h1 does not advertise this speed". The claim is wrong because
the function is called after $h1 already advertised a subset of speeds.

In case $h1 supports only two speeds, it will advertise a single speed
which will be later removed because of previously mentioned bug. This
results in the test needlessly failing. When more than two speeds are
supported this is not an issue because the first advertised speed
is the lowest one.

Fix this by not removing any speed from the list of commonly advertised
speeds.

a57066b1a0 Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
The UDP reuseport conflict was a little bit tricky.

The net-next code, via bpf-next, extracted the reuseport handling
into a helper so that the BPF sk lookup code could invoke it.

At the same time, the logic for reuseport handling of unconnected
sockets changed via commit efc6b6f6c3
which changed the logic to carry on the reuseport result into the
rest of the lookup loop if we do not return immediately.

This requires moving the reuseport_has_conns() logic into the callers.

While we are here, get rid of inline directives as they do not belong
in foo.c files.

The other changes were cases of more straightforward overlapping
modifications.

34fe5a1cf9 ipv6: fib6_select_path can not use out path for nexthop objects
Brian reported a crash in IPv6 code when using rpfilter with a setup
running FRR and external nexthop objects. The root cause of the crash
is fib6_select_path setting fib6_nh in the result to NULL because of
an improper check for nexthop objects.

More specifically, rpfilter invokes ip6_route_lookup with flowi6_oif
set causing fib6_select_path to be called with have_oif_match set.
fib6_select_path has early check on have_oif_match and jumps to the
out label which presumes a builtin fib6_nh. This path is invalid for
nexthop objects; for external nexthops fib6_select_path needs to just
return if the fib6_nh has already been set in the result otherwise it
returns after the call to nexthop_path_fib6_result. Update the check
on have_oif_match to not bail on external nexthops.

Update selftests for this problem.

0b8241fe3c selftests: mptcp: capture pcap on both sides
When investigating performance issues that involve latency / loss /
reordering it is useful to have the pcap from the sender-side as it
allows to easier infer the state of the sender's congestion-control,
loss-recovery, etc.

Allow the selftests to capture a pcap on both sender and receiver so
that this information is not lost when reproducing.

This patch also improves the file names. Instead of:

  ns4-5ee79a56-X4O6gS-ns3-5ee79a56-X4O6gS-MPTCP-MPTCP-10.0.3.1.pcap

We now have something like for the same test:

  5ee79a56-X4O6gS-ns3-ns4-MPTCP-MPTCP-10.0.3.1-10030-connector.pcap
  5ee79a56-X4O6gS-ns3-ns4-MPTCP-MPTCP-10.0.3.1-10030-listener.pcap

It was a connection from ns3 to ns4, better to start with ns3 then. The
port is also added, easier to find the trace we want.

mptcp connections.

In order to compare throughput over consecutive runs add an option
to provide the file size on the command line: "-f 128000".

Also add an option, -t, to enable tcp tests. This is useful to
compare throughput of mptcp connections and tcp connections.

Example: run tests with a 4mb file size, 300ms delay 0.01% loss,
default gso/tso/gro settings and with large write/blocking io:

mptcp_connect.sh -t -f $((4 * 1024 * 1024)) -d 300 -l 0.01%  -r 0 -e "" -m mmap

0558c39604 selftests/net: plug rxtimestamp test into kselftest framework
Run rxtimestamp as part of TEST_PROGS. Analogous to other tests, add
new rxtimestamp.sh wrapper script, so that the test runs isolated
from background traffic in a private network namespace.

Also ignore failures of test case #6 by default. This case verifies
that a receive timestamp is not reported if timestamp reporting is
enabled for a socket, but generation is disabled. Receive timestamp
generation has to be enabled globally, as no associated socket is
known yet. A background process that enables rx timestamp generation
therefore causes a false positive. Ntpd is one example that does.

Add a "--strict" option to cause failure in the event that any test
case fails, including test #6. This is useful for environments that
are known to not have such background processes.

Tested:
make -C tools/testing/selftests TARGETS="net" run_tests

0e6fbe39bd net/tls(TLS_SW): Add selftest for 'chunked' sendfile test
This selftest tests for cases where sendfile's 'count'
parameter is provided with a size greater than the intended
file size.

Motivation: When sendfile is provided with 'count' parameter
value that is greater than the size of the file, kTLS example
fails to send the file correctly. Last chunk of the file is
not sent, and the data integrity is compromised.
The reason is that the last chunk has MSG_MORE flag set
because of which it gets added to pending records, but is
not pushed.
Note that if user space were to send SSL_shutdown control
message, pending records would get flushed and the issue
would not happen. So a shutdown control message following
sendfile can mask the issue.
