Currently, hvsock does not implement any delayed or background close
logic. Whenever the hvsock socket is closed, a FIN is sent to the peer, and
the last reference to the socket is dropped, which leads to a call to
.destruct where the socket can hang indefinitely waiting for the peer to
close it's side. The can cause the user application to hang in the close()
call.

This change implements proper STREAM(TCP) closing handshake mechanism by
sending the FIN to the peer and the waiting for the peer's FIN to arrive
for a given timeout. On timeout, it will try to terminate the connection
(i.e. a RST). This is in-line with other socket providers such as virtio.

This change does not address the hang in the vmbus_hvsock_device_unregister
where it waits indefinitely for the host to rescind the channel. That
should be taken up as a separate fix.

flow_offload: fix CVLAN support

When the flow_offload infrastructure was added, CVLAN matches weren't
 plumbed through, and flow_rule_match_vlan() was incorrectly called in
 the mlx5 driver when populating CVLAN match information.  This series
 adds flow_rule_match_cvlan(), and uses it in the mlx5 code.
Both patches should also go to 5.1 stable.

When flow_rule_match_XYZ() functions were first introduced,
flow_rule_match_cvlan() for inner vlan is missing.

In mlx5_core driver, to get inner vlan key and mask, flow_rule_match_vlan()
is just called, which is wrong because it obtains outer vlan information by
FLOW_DISSECTOR_KEY_VLAN.

This commit fixes this by changing to call flow_rule_match_cvlan() after
it's added.

Currently, nla_put_iflink() doesn't put the IFLA_LINK attribute when
iflink == ifindex.

In some cases, a device can be created in a different netns with the
same ifindex as its parent. That device will not dump its IFLA_LINK
attribute, which can confuse some userspace software that expects it.
For example, if the last ifindex created in init_net and foo are both
8, these commands will trigger the issue:

    ip link add parent type dummy                   # ifindex 9
    ip link add link parent netns foo type macvlan  # ifindex 9 in ns foo

So, in case a device puts the IFLA_LINK_NETNSID attribute in a dump,
always put the IFLA_LINK attribute as well.

Thanks to Dan Winship for analyzing the original OpenShift bug down to
the missing netlink attribute.

time on passive Fast Open in "retrans_stamp". However the
timestamp is not reset upon the handshake has completed. As a
result, future data packet retransmission may not update it in
tcp_retransmit_skb(). This may lead to socket aborting earlier
unexpectedly by retransmits_timed_out() since retrans_stamp remains
the SYNACK rtx time.

This bug only manifests on passive TFO sender that a) suffered
SYNACK timeout and then b) stalls on very first loss recovery. Any
successful loss recovery would reset the timestamp to avoid this

The test_lru_map is relying on marking the LRU map entry via regular
BPF map lookup from system call side. This is basically for simplicity
reasons. Given we fixed marking entries in that case, the test needs
to be fixed as well. Here we add a small drop-in replacement to retain
existing behavior for the tests by marking out of the BPF program and
transferring the retrieved value out via temporary map. This also adds
new test cases to track the new behavior where two elements are marked,
one via system call side and one via program side, where the next update
then evicts the key looked up only from system call side.

One of the biggest issues we face right now with picking LRU map over
regular hash table is that a map walk out of user space, for example,
to just dump the existing entries or to remove certain ones, will
completely mess up LRU eviction heuristics and wrong entries such
as just created ones will get evicted instead. The reason for this
is that we mark an entry as "in use" via bpf_lru_node_set_ref() from
system call lookup side as well. Thus upon walk, all entries are
being marked, so information of actual least recently used ones
are "lost".

In case of Cilium where it can be used (besides others) as a BPF
based connection tracker, this current behavior causes disruption
upon control plane changes that need to walk the map from user space
to evict certain entries. Discussion result from bpfconf [0] was that
we should simply just remove marking from system call side as no
good use case could be found where it's actually needed there.
Therefore this patch removes marking for regular LRU and per-CPU
flavor. If there ever should be a need in future, the behavior could
be selected via map creation flag, but due to mentioned reason we
avoid this here.

Add a callback map_lookup_elem_sys_only() that map implementations
could use over map_lookup_elem() from system call side in case the
map implementation needs to handle the latter differently than from
the BPF data path. If map_lookup_elem_sys_only() is set, this will
be preferred pick for map lookups out of user space. This hook is
used in a follow-up fix for LRU map, but once development window
opens, we can convert other map types from map_lookup_elem() (here,
the one called upon BPF_MAP_LOOKUP_ELEM cmd is meant) over to use
the callback to simplify and clean up the latter.

Pull PCI updates from Bjorn Helgaas:
 "Enumeration changes:

   - Add _HPX Type 3 settings support, which gives firmware more
     influence over device configuration (Alexandru Gagniuc)

   - Support fixed bus numbers from bridge Enhanced Allocation
     capabilities (Subbaraya Sundeep)

   - Add "external-facing" DT property to identify cases where we
     require IOMMU protection against untrusted devices (Jean-Philippe
     Brucker)

   - Enable PCIe services for host controller drivers that use managed
     host bridge alloc (Jean-Philippe Brucker)

   - Log PCIe port service messages with pci_dev, not the pcie_device
     (Frederick Lawler)

   - Convert pciehp from pciehp_debug module parameter to generic
     dynamic debug (Frederick Lawler)

  Peer-to-peer DMA:

   - Add whitelist of Root Complexes that support peer-to-peer DMA
     between Root Ports (Christian König)

  Native controller drivers:

   - Add PCI host bridge DMA ranges for bridges that can't DMA
     everywhere, e.g., iProc (Srinath Mannam)

   - Add Amazon Annapurna Labs PCIe host controller driver (Jonathan
     Chocron)

   - Fix Tegra MSI target allocation so DMA doesn't generate unwanted
     MSIs (Vidya Sagar)

   - Fix of_node reference leaks (Wen Yang)

   - Fix Hyper-V module unload & device removal issues (Dexuan Cui)

   - Cleanup R-Car driver (Marek Vasut)
