macvlan: Allow some packets to bypass broadcast queue
This patch series allows some packets to bypass the broadcast
queue on receive. Currently all multicast packets are queued
on receive and then processed in a work queue. This is to avoid
an unbounded amount of work occurring in the receive path, as
one broadcast packet could easily translate into 4,000 packets.
However, for multicast packets with just one receiver (possible
for IPv6 ND), this introduces unnecessary latency as the packet
will go to exactly one device.
This series allows such multicast packets to be processed inline.
It also adds a toggle which lets the admin control what threshold
to set between queueing and not queueing. A follow-up patch for
iproute will be posted.
====================

Make the broadcast cutoff configurable through netlink. Note
that macvlan is weird because there is no central device for
us to configure (the lowerdev could be anything). So all the
options are duplicated over what could be thousands of child
devices.
IFLA_MACVLAN_BC_QUEUE_LEN took the approach of taking the maximum
of all child device settings. This is unnecessary as we could
simply store the option in the port device and take the last
child device that gets updated as the value to use.

Signed-off-by: David S. Miller <davem@davemloft.net>
As it stands all broadcast and multicast packets are queued and
processed in a work queue. This is so that we don't overwhelm
the receive softirq path by generating thousands of packets or
more (see commit 412ca1550c "macvlan: Move broadcasts into a
work queue").
As such all multicast packets will be delayed, even if they will
be received by a single macvlan device. As using a workqueue
is not free in terms of latency, we should avoid this where possible.
This patch adds a new filter to determine which addresses should
be delayed and which ones won't. This is done using a crude
counter of how many times an address has been added to the macvlan
port (ha->synced). For now if an address has been added more than
once, then it will be considered to be broadcast. This could be
tuned further by making this threshold configurable.

Patch 4 adds a new test to validate that the 'subflows' field reported

Only the in-kernel PM uses the number of address and subflow limits
allowed per connection.
It then makes more sense not to display such info when other PMs are
used not to confuse the userspace by showing limits not being used.
While at it, we can get rid of the "val" variable and add indentations
instead.
It would have been good to have done this modification directly in
commit 4d25247d3a ("mptcp: bypass in-kernel PM restrictions for non-kernel PMs")
but as we change a bit the behaviour, it is fine not to backport it to

Add support for sockmap to vsock.
We're testing usage of vsock as a way to redirect guest-local UDS
requests to the host and this patch series greatly improves the
performance of such a setup.
Compared to copying packets via userspace, this improves throughput by
121% in basic testing.
Tested as follows.
Setup: guest unix dgram sender -> guest vsock redirector -> host vsock
server
Threads: 1
Payload: 64k
No sockmap:
- 76.3 MB/s
- The guest vsock redirector was
"socat VSOCK-CONNECT:2:1234 UNIX-RECV:/path/to/sock"
Using sockmap (this patch):
- 168.8 MB/s (+121%)
- The guest redirector was a simple sockmap echo server,
redirecting unix ingress to vsock 2:1234 egress.
- Same sender and server programs
*Note: these numbers are from RFC v1
Only the virtio transport has been tested. The loopback transport was
used in writing bpf/selftests, but not thoroughly tested otherwise.
This series requires the skb patch.
Changes in v4:
- af_vsock: fix parameter alignment in vsock_dgram_recvmsg()
- af_vsock: add TCP_ESTABLISHED comment in vsock_dgram_connect()
- vsock/bpf: change ret type to bool
Changes in v3:
- vsock/bpf: Refactor wait logic in vsock_bpf_recvmsg() to avoid
backwards goto
- vsock/bpf: Check psock before acquiring slock
- vsock/bpf: Return bool instead of int of 0 or 1
- vsock/bpf: Wrap macro args __sk/__psock in parens
- vsock/bpf: Place comment trailer */ on separate line
Changes in v2:
- vsock/bpf: rename vsock_dgram_* -> vsock_*
- vsock/bpf: change sk_psock_{get,put} and {lock,release}_sock() order
to minimize slock hold time
- vsock/bpf: use "new style" wait
- vsock/bpf: fix bug in wait log

91 | static void xhci_msix_sync_irqs(struct xhci_hcd *xhci)

This could be solved by adding another #ifdef, but as there is
a trend towards removing CONFIG_PM checks in favor of helper
macros, do the same conversion here and use pm_ptr() to get
either a function pointer or NULL but avoid the warning.
As the hidden functions reference some other symbols, make

YMF744 and newer store the base IO ports in separate PCI config registers.
Since these registers were not restored, when set to a non-default value,
features that rely on them (FM, MPU401, gameport) were not functional
after restore, as their respective IO ports were reset to their defaults.

The registers were previously allocated when CONFIG_PM_SLEEP was set,
however this only saved an insignificant amount of memory otherwise.
