Add custom "__kvm_pmu_event_filter" structure to improve pmu event
filter settings. Simplifies event filter setup by organizing event
filter parameters in a cleaner, more organized way.
Alternatively, selftests could use a struct overlay ala vcpu_set_msr()
to avoid dynamically allocating the array:
struct {
struct kvm_msrs header;
struct kvm_msr_entry entry;
} buffer = {};
memset(&buffer, 0, sizeof(buffer));
buffer.header.nmsrs = 1;
buffer.entry.index = msr_index;
buffer.entry.data = msr_value;
but the extra layer added by the nested structs is counterproductive
to writing efficient, clean code.

Implement a new test program mptcpify: if the family is AF_INET or
AF_INET6, the type is SOCK_STREAM, and the protocol ID is 0 or
IPPROTO_TCP, set it to IPPROTO_MPTCP. It will be hooked in
update_socket_protocol().
Extend the MPTCP test base, add a selftest test_mptcpify() for the
mptcpify case. Open and load the mptcpify test prog to mptcpify the
TCP sockets dynamically, then use start_server() and connect_to_fd()
to create a TCP socket, but actually what's created is an MPTCP
socket, which can be verified through 'getsockopt(SOL_PROTOCOL)'
and 'getsockopt(MPTCP_INFO)'.

This selftest is designed for testing the support of NEXT-C-SID flavor
for SRv6 End.X 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, according to the topology depicted in the selftest script file.
The test considers SRv6 routers implementing IPv4/IPv6 L3 VPNs leveraged
by hosts for communicating with each other. Such routers i) apply
different SRv6 Policies to the traffic received from connected hosts,
considering the IPv4 or IPv6 protocols; ii) use the NEXT-C-SID
compression mechanism for encoding several SRv6 segments within a single
128-bit SID address, referred to as a Compressed SID (C-SID) container.
The NEXT-C-SID is provided as a "flavor" of the SRv6 End.X behavior,
enabling it to properly process the C-SID containers. The correct
execution of the enabled NEXT-C-SID SRv6 End.X behavior is verified
through reachability tests carried out between hosts belonging to the
same VPN.

This test verifies whether the encapsulated packets have the correct
configured TTL. It does so by sending ICMP packets through the test
topology and mirroring them to a gretap netdevice. On a busy host
however, more than just the test ICMP packets may end up flowing
through the topology, get mirrored, and counted. This leads to
potential spurious failures as the test observes much more mirrored
packets than the sent test packets, and assumes a bug.
Fix this by tightening up the mirror action match. Change it from
matchall to a flower classifier matching on ICMP packets specifically.

From: Eric Garver <eric@garver.life>
This adds an explicit drop action. This is used by OVS to drop packets
for which it cannot determine what to do. An explicit action in the
kernel allows passing the reason _why_ the packet is being dropped or
zero to indicate no particular error happened (i.e: OVS intentionally
dropped the packet).
Since the error codes coming from userspace mean nothing for the kernel,
we squash all of them into only two drop reasons:
- OVS_DROP_EXPLICIT_WITH_ERROR to indicate a non-zero value was passed
- OVS_DROP_EXPLICIT to indicate a zero value was passed (no error)
e.g. trace all OVS dropped skbs
# perf trace -e skb:kfree_skb --filter="reason >= 0x30000"
[..]
106.023 ping/2465 skb:kfree_skb(skbaddr: 0xffffa0e8765f2000, \
location:0xffffffffc0d9b462, protocol: 2048, reason: 196611)
reason: 196611 --> 0x30003 (OVS_DROP_EXPLICIT)
Also, this patch allows ovs-dpctl.py to add explicit drop actions as:
"drop" -> implicit empty-action drop
"drop(0)" -> explicit non-error action drop
"drop(42)" -> explicit error action drop

Our ABI opts to provide future proofing by defining a much larger
SVE_VQ_MAX than the architecture actually supports. Since we use
this define to control the size of our vector data buffers this results
in a lot of overhead when we initialise which can be a very noticable
problem in emulation, we fill buffers that are orders of magnitude
larger than we will ever actually use even with virtual platforms that
provide the full range of architecturally supported vector lengths.
Define and use the actual architecture maximum to mitigate this.

Add a test case to check whether sockmap redirection works correctly
when data length returned by stream_parser is less than skb->len.
In addition, this test checks whether strp_done is called correctly.
The reason is that we returns skb->len - 1 from the stream_parser, so
the last byte in the skb will be held by strp->skb_head. Therefore,
if strp_done is not called to free strp->skb_head, we'll get a memleak
warning.
