Add basic test coverage for specifying the shadow stack for a newly
created thread via clone3(), including coverage of the newly extended
argument structure. We check that a user specified shadow stack can be
provided, and that invalid combinations of parameters are rejected.

The clone_args structure is extensible, with the syscall passing in the
length of the structure. Inside the kernel we use copy_struct_from_user()
to read the struct but this has the unfortunate side effect of silently
accepting some overrun in the structure size providing the extra data is
all zero
In order to make it easier to add more configuration for the tests and
more support for runtime detection of when tests can be run pass the
structure describing the tests into test_clone3() rather than picking
the arguments out of it and have that function do all the per-test work.

Unlike with the normal stack there is no API for configuring the shadow

The test_memcontrol selftest consistently fails its test_memcg_low
sub-test due to the fact that its 3rd test child cgroup which
have a memmory.low of 0 have low event count. This happens when
memory_recursiveprot mount option is enabled which is the default
setting used by systemd to mount cgroup2
The test_memcg_protection() function is used for the test_memcg_min and
test_memcg_low sub-tests. This function generates a set of parent/child
cgroups like:
parent: memory.min/low = 50M
child 0: memory.min/low = 75M, memory.current = 50M
child 1: memory.min/low = 25M, memory.current = 50
v7:
- Skip the vmscan change as the mem_cgroup_usage() check for now as
it is currently redundant.

- The memcg_test_low failure is indeed due to the memory_recursiveprot

This change introduces the netlink commands needed to add, get, delete
and swap keys for a specific peer.
Userspace is expected to use these commands to create, inspect (non
sensitive data only), destroy and rotate session keys for a specific
peer.

Add support for learning the new address in case of change.

IV wrap-around is cryptographically dangerous for a number of ciphers,
therefore kill the key and inform userspace (via netlink) should the
IV space go exhausted.
Userspace has two ways of deciding when the key has to be renewed before
exhausting the IV space:
1) time based approach:

With this change an ovpn instance will be able to stay connected to
multiple remote endpoints.
This functionality is strictly required when running ovpn on an
OpenVPN server.

When sending an skb over a socket using skb_send_sock_locked(),

With this change ovpn is allowed to communicate to peers also via TCP.
Parsing of incoming messages is implemented through the strparser API.
Note that ovpn redefines sk_prot and sk_socket->ops for the TCP socket
used to communicate with the peer.
For this reason it needs to access inet6_stream_op
This change implements encryption/decryption and

Packets received over the socket are forwarded to the user device.
Implementation is UDP only. TCP will be added by a later patch.
Note: no decryption/decapsulation exists yet, packets are forwarded as

OpenVPN is a userspace software existing since around 2005 that allows

So far OpenVPN has implemented all operations in userspace, which

An ovpn interface configured in MP mode will keep carrier always
on and let the user decide when to bring it administratively up and
down.
This way a MP node (i.e. a server) will keep its interface always
up and running, even when no peer is connected.

Not all tasks have an ABI associated or vDSO mapped,
for example kthreads never do.
If such a task ever ends up calling stack_top(), it will derefence the
NULL ABI pointer and crash.
This can for example happen when using kunit:
mips_stack_top+0x28/0xc0
arch_pick_mmap_layout+0x190/0x220
The configuration generated by kunit ends up with big endian.
A new kunit configuration for little endian is to be added.
To make the difference clearer spell out the endianness in the kunit
reference config.
