fcf4927632 selftests: forwarding: lib: Add helpers for IP address handling
In order to generate IGMPv3 and MLDv2 packets on the fly, we will need
helpers to expand IPv4 and IPv6 addresses given as parameters in
mausezahn payload notation. Add helpers that do it.

329c9cd769 selftests: net: udpgso_bench_tx: Cater for pending datagrams zerocopy benchmarking
The test tool can check that the zerocopy number of completions value is
valid taking into consideration the number of datagram send calls. This can
catch the system into a state where the datagrams are still in the system
(for example in a qdisk, waiting for the network interface to return a
completion notification, etc).

This change adds a retry logic of computing the number of completions up to
a configurable (via CLI) timeout (default: 2 seconds).

dafe93b9ee selftests: net: udpgso_bench: Fix racing bug between the rx/tx programs
"udpgro_bench.sh" invokes udpgso_bench_rx/udpgso_bench_tx programs
subsequently and while doing so, there is a chance that the rx one is not
ready to accept socket connections. This racing bug could fail the test
with at least one of the following:

./udpgso_bench_tx: connect: Connection refused
./udpgso_bench_tx: sendmsg: Connection refused
./udpgso_bench_tx: write: Connection refused

This change addresses this by making udpgro_bench.sh wait for the rx
program to be ready before firing off the tx one - up to a 10s timeout.

a6efc42a86 selftest: net: Improve IPV6_TCLASS/IPV6_HOPLIMIT tests apparmor compatibility
"tcpdump" is used to capture traffic in these tests while using a random,
temporary and not suffixed file for it. This can interfere with apparmor
configuration where the tool is only allowed to read from files with
'known' extensions.

The MINE type application/vnd.tcpdump.pcap was registered with IANA for
pcap files and .pcap is the extension that is both most common but also
aligned with standard apparmor configurations. See TCPDUMP(8) for more
details.

This improves compatibility with standard apparmor configurations by
using ".pcap" as the file extension for the tests' temporary files.

8dbdf24f4e selftests: mptcp: userspace: avoid read errors
During the cleanup phase, the server pids were killed with a SIGTERM
directly, not using a SIGUSR1 first to quit safely. As a result, this
test was often ending with two error messages:

  read: Connection reset by peer

While at it, use a for-loop to terminate all the PIDs the same way.

Also the different files are now removed after having killed the PIDs
using them. It makes more sense to do that in this order.

ca22da2fbd act_mirred: use the backlog for nested calls to mirred ingress
William reports kernel soft-lockups on some OVS topologies when TC mirred
egress->ingress action is hit by local TCP traffic [1].
The same can also be reproduced with SCTP (thanks Xin for verifying), when
client and server reach themselves through mirred egress to ingress, and
one of the two peers sends a "heartbeat" packet (from within a timer).

Enqueueing to backlog proved to fix this soft lockup; however, as Cong
noticed [2], we should preserve - when possible - the current mirred
behavior that counts as "overlimits" any eventual packet drop subsequent to
the mirred forwarding action [3]. A compromise solution might use the
backlog only when tcf_mirred_act() has a nest level greater than one:
change tcf_mirred_forward() accordingly.

Also, add a kselftest that can reproduce the lockup and verifies TC mirred
ability to account for further packet drops after TC mirred egress->ingress
(when the nest level is 1).

 [1] https://lore.kernel.org/netdev/33dc43f587ec1388ba456b4915c75f02a8aae226.1663945716.git.dcaratti@redhat.com/
 [2] https://lore.kernel.org/netdev/Y0w%2FWWY60gqrtGLp@pop-os.localdomain/
 [3] such behavior is not guaranteed: for example, if RPS or skb RX
     timestamping is enabled on the mirred target device, the kernel
     can defer receiving the skb and return NET_RX_SUCCESS inside
     tcf_mirred_forward().

057fb03160 selftests: net: tcp_mmap: populate pages in send path
In commit 72653ae530 ("selftests: net: tcp_mmap:
Use huge pages in send path") I made a change to use hugepages
for the buffer used by the client (tx path)

Today, I understood that the cause for poor zerocopy
performance was that after a mmap() for a 512KB memory
zone, kernel uses a single zeropage, mapped 128 times.

This was really the reason for poor tx path performance
in zero copy mode, because this zero page refcount is
under high pressure, especially when TCP ACK packets
are processed on another cpu.

We need either to force a COW on all the memory range,
or use MAP_POPULATE so that a zero page is not abused.

903848249a selftests/net: toeplitz: fix race on tpacket_v3 block close
Avoid race between process wakeup and tpacket_v3 block timeout.

The test waits for cfg_timeout_msec for packets to arrive. Packets
arrive in tpacket_v3 rings, which pass packets ("frames") to the
process in batches ("blocks"). The sk waits for req3.tp_retire_blk_tov
msec to release a block.

Set the block timeout lower than the process waiting time, else
the process may find that no block has been released by the time it
scans the socket list. Convert to a ring of more than one, smaller,
blocks with shorter timeouts. Blocks must be page aligned, so >= 64KB.

3c107f36db selftests/net: mv bpf/nat6to4.c to net folder
There are some issues with the bpf/nat6to4.c building.

1. It use TEST_CUSTOM_PROGS, which will add the nat6to4.o to
   kselftest-list file and run by common run_tests.
2. When building the test via `make -C tools/testing/selftests/
   TARGETS="net"`, the nat6to4.o will be build in selftests/net/bpf/
   folder. But in test udpgro_frglist.sh it refers to ../bpf/nat6to4.o.
   The correct path should be ./bpf/nat6to4.o.
3. If building the test via `make -C tools/testing/selftests/ TARGETS="net"
   install`. The nat6to4.o will be installed to kselftest_install/net/
   folder. Then the udpgro_frglist.sh should refer to ./nat6to4.o.

To fix the confusing test path, let's just move the nat6to4.c to net folder
and build it as TEST_GEN_FILES.

d68ff8ad33 selftests/net: l2_tos_ttl_inherit.sh: Ensure environment cleanup on failure.
Use 'set -e' and an exit handler to stop the script if a command fails
and ensure the test environment is cleaned up in any case. Also, handle
the case where the script is interrupted by SIGINT.

The only command that's expected to fail is 'wait $ping_pid', since
it's killed by the script. Handle this case with '|| true' to make it
play well with 'set -e'.

Finally, return the Kselftest SKIP code (4) when the script breaks
because of an environment problem or a command line failure. The 0 and
1 return codes should now reliably indicate that all tests have been
run (0: all tests run and passed, 1: all tests run but at least one
failed, 4: test script didn't run completely).

c53cb00f79 selftests/net: l2_tos_ttl_inherit.sh: Run tests in their own netns.
This selftest currently runs half in the current namespace and half in
a netns of its own. Therefore, the test can fail if the current
namespace is already configured with incompatible parameters (for
example if it already has a veth0 interface).

Adapt the script to put both ends of the veth pair in their own netns.
Now veth0 is created in NS0 instead of the current namespace, while
veth1 is set up in NS1 (instead of the 'testing' netns).

The user visible netns names are randomised to minimise the risk of
conflicts with already existing namespaces. The cleanup() function
doesn't need to remove the virtual interface anymore: deleting NS0 and
NS1 automatically removes the virtual interfaces they contained.

We can remove $ns, which was only used to run ip commands in the
'testing' netns (let's use the builtin "-netns" option instead).
However, we still need a similar functionality as ping and tcpdump
now need to run in NS0. So we now have $RUN_NS0 for that.

9c4d7f45d6 selftests: net: fix cleanup_v6() for arp_ndisc_evict_nocarrier
The cleanup_v6() will cause the arp_ndisc_evict_nocarrier script exit
with 255 (No such file or directory), even the tests are good:

 # selftests: net: arp_ndisc_evict_nocarrier.sh
 # run arp_evict_nocarrier=1 test
 # RTNETLINK answers: File exists
 # ok
 # run arp_evict_nocarrier=0 test
 # RTNETLINK answers: File exists
 # ok
 # run all.arp_evict_nocarrier=0 test
 # RTNETLINK answers: File exists

 # run ndisc_evict_nocarrier=1 test

 # ok
 # run all.ndisc_evict_nocarrier=0 test
 # ok
 not ok 1 selftests: net: arp_ndisc_evict_nocarrier.sh # exit=255

This is because it's trying to modify the parameter for ipv4 instead.

Also, tests for ipv6 (run_ndisc_evict_nocarrier_enabled() and
run_ndisc_evict_nocarrier_disabled() are working on veth1, reflect
this fact in cleanup_v6().

1573c68820 selftests: net: fix cmsg_so_mark.sh test hang
This cmsg_so_mark.sh test will hang on non-amd64 systems because of the
infinity loop for argument parsing in cmsg_sender.

Variable "o" in cs_parse_args() for taking getopt() should be an int,
otherwise it will be 255 when getopt() returns -1 on non-amd64 system
and thus causing infinity loop.

c0d999348e ipv4: Fix incorrect route flushing when table ID 0 is used
Cited commit added the table ID to the FIB info structure, but did not
properly initialize it when table ID 0 is used. This can lead to a route
in the default VRF with a preferred source address not being flushed
when the address is deleted.

Consider the following example:

 # ip address add dev dummy1 192.0.2.1/28
 # ip address add dev dummy1 192.0.2.17/28
 # ip route add 198.51.100.0/24 via 192.0.2.2 src 192.0.2.17 metric 100
 # ip route add table 0 198.51.100.0/24 via 192.0.2.2 src 192.0.2.17 metric 200
 # ip route show 198.51.100.0/24
 198.51.100.0/24 via 192.0.2.2 dev dummy1 src 192.0.2.17 metric 100
 198.51.100.0/24 via 192.0.2.2 dev dummy1 src 192.0.2.17 metric 200

Both routes are installed in the default VRF, but they are using two
different FIB info structures. One with a metric of 100 and table ID of
254 (main) and one with a metric of 200 and table ID of 0. Therefore,
when the preferred source address is deleted from the default VRF,
the second route is not flushed:

 # ip address del dev dummy1 192.0.2.17/28
 # ip route show 198.51.100.0/24
 198.51.100.0/24 via 192.0.2.2 dev dummy1 src 192.0.2.17 metric 200

Fix by storing a table ID of 254 instead of 0 in the route configuration
structure.

Add a test case that fails before the fix:

 # ./fib_tests.sh -t ipv4_del_addr

 IPv4 delete address route tests
     Regular FIB info
     TEST: Route removed from VRF when source address deleted            [ OK ]
     TEST: Route in default VRF not removed                              [ OK ]
     TEST: Route removed in default VRF when source address deleted      [ OK ]
     TEST: Route in VRF is not removed by address delete                 [ OK ]

f96a3d7455 ipv4: Fix incorrect route flushing when source address is deleted
Cited commit added the table ID to the FIB info structure, but did not
prevent structures with different table IDs from being consolidated.
This can lead to routes being flushed from a VRF when an address is
deleted from a different VRF.

Fix by taking the table ID into account when looking for a matching FIB
info. This is already done for FIB info structures backed by a nexthop
object in fib_find_info_nh().

Add test cases that fail before the fix:

This patch makes server_evts and client_evts global in userspace_pm.sh,
then these two variables could be used in test_announce(), test_remove()
and test_subflows(). The local variable 'evts' in these three functions
then could be dropped.

Also move local variable 'file' as a global one.

7dff74f571 selftests: mptcp: enhance userspace pm tests
Some userspace pm tests failed since pm listener events have been added.
Now MPTCP_EVENT_LISTENER_CREATED event becomes the first item in the
events list like this:

 type:15,family:2,sport:10006,saddr4:0.0.0.0
 type:1,token:3701282876,server_side:1,family:2,saddr4:10.0.1.1,...

And no token value in this MPTCP_EVENT_LISTENER_CREATED event.

This patch fixes this by specifying the type 1 item to search for token
values.

5f17f8e315 selftests: mptcp: declare var as local
Just to avoid classical Bash pitfall where variables are accidentally
overridden by other functions because the proper scope has not been
defined.

That's also what is done in other MPTCP selftests scripts where all non
local variables are defined at the beginning of the script and the
others are defined with the "local" keyword.

de2392028a selftests: mptcp: clearly declare global ns vars
It is clearer to declare these global variables at the beginning of the
file as it is done in other MPTCP selftests rather than in functions in
the middle of the script.

So for uniformity reason, we can do the same here in mptcp_sockopt.sh.
