Konrad Sewiłło-Jopek cf2ba7d7f8 arp: Implement sticky ARP mode for interfaces.
Provide sticky ARP flag for network interface which marks it as the
"sticky" one similarly to what we have for bridges. Once interface is
marked sticky, any address resolved using the ARP will be saved as a
static one in the ARP table. Such functionality may be used to prevent
ARP spoofing or to decrease latencies in Ethernet networks.

The drawbacks include potential limitations in usage of ARP-based
load-balancers and high-availability solutions such as carp(4).

The implemented option is disabled by default, therefore should not
impact the default behaviour of the networking stack.

Alan Somers 27dfb5f33f Correctly measure system load averages > 1024
The old fixed-point arithmetic used for calculating load averages had an
overflow at 1024.  So on systems with extremely high load, the observed
load average would actually fall back to 0 and shoot up again, creating
a kind of sawtooth graph.

Fix this by using 64-bit math internally, while still reporting the load
average to userspace as a 32-bit number.

Randall Stewart 57703f72c8 tcp: Add support for DSACK based reordering window to rack.
The rack stack, with respect to the rack bits in it, was originally built based
on an early I-D of rack. In fact at that time the TLP bits were in a separate
I-D. The dynamic reordering window based on DSACK events was not present
in rack at that time. It is now part of the RFC and we need to update our stack
to include these features. However we want to have a way to control the feature
so that we can, if the admin decides, make it stay the same way system wide as
well as via socket option. The new sysctl and socket option has the following
meaning for setting:

00 (0) - Keep the old way, i.e. reordering window is 1 and do not use DSACK bytes to add to reorder window
01 (1) - Change the Reordering window to 1/4 of an RTT but do not use DSACK bytes to add to reorder window
10 (2) - Keep the reordering window as 1, but do use SACK bytes to add additional 1/4 RTT delay to the reorder window
11 (3) - reordering window is 1/4 of an RTT and add additional DSACK bytes to increase the reordering window (RFC behavior)

The default currently in the sysctl is 3 so we get standards based behavior.

programs could not tell if they missed messages or messages had been
truncated because of overflows. Since programs historically do not
expect to get receive overflow errors, this behavior is not the
default.

This is really really important for programs that use route(4) to keep
in sync with the system. If we loose a message then we need to reload
the full system state, otherwise the behaviour from that point is
undefined and can lead to chasing bogus bug reports.

Randall Stewart b89c5a3e88 tcp: Add a socket option to rack
so we can test various changes to the slop value in timers.

Timer_slop, in TCP, has been 200ms for a long time. This value dates back
a long time when delayed ack timers were longer and links were slower. A
200ms timer slop allows 1 MSS to be sent over a 60kbps link. Its possible that
lowering this value to something more in line with todays delayed ack values (40ms)
might improve TCP. This bit of code makes it so rack can, via a socket option,
adjust the timer slop.

Alex Richardson 8054ce555f Expose clang's alignment builtins and use them for roundup2/rounddown2
This makes roundup2/rounddown2 type- and const-preserving and allows
using it on pointer types without casting to uintptr_t first. Not
performing pointer-to-integer conversions also helps the compiler's
optimization passes and can therefore result in better code generation.
When using it with integer values there should be no change other than
the compiler checking that the alignment value is a valid power-of-two.

I originally implemented these builtins for CHERI a few years ago and
they have been very useful for CheriBSD. However, they are also useful
for non-CHERI code so I was able to upstream them for Clang 10.0.

Rationale from the clang documentation:
Clang provides builtins to support checking and adjusting alignment
of pointers and integers. These builtins can be used to avoid relying
on implementation-defined behavior of arithmetic on integers derived
from pointers. Additionally, these builtins retain type information
and, unlike bitwise arithmetic, they can perform semantic checking on
the alignment value.

There is also a feature request for GCC, so GCC may also support it in
the future: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98641

Andrew Gallatin c76896074b Filter TCP connections to SO_REUSEPORT_LB listen sockets by NUMA domain
In order to efficiently serve web traffic on a NUMA
machine, one must avoid as many NUMA domain crossings as
possible. With SO_REUSEPORT_LB, a number of workers can share a
listen socket. However, even if a worker sets affinity to a core
or set of cores on a NUMA domain, it will receive connections
associated with all NUMA domains in the system. This will lead to
cross-domain traffic when the server writes to the socket or
calls sendfile(), and memory is allocated on the server's local
NUMA node, but transmitted on the NUMA node associated with the
TCP connection. Similarly, when the server reads from the socket,
he will likely be reading memory allocated on the NUMA domain
associated with the TCP connection.

This change provides a new socket ioctl, TCP_REUSPORT_LB_NUMA. A
server can now tell the kernel to filter traffic so that only
incoming connections associated with the desired NUMA domain are
given to the server. (Of course, in the case where there are no
servers sharing the listen socket on some domain, then as a
fallback, traffic will be hashed as normal to all servers sharing
the listen socket regardless of domain). This allows a server to
deal only with traffic that is local to its NUMA domain, and
avoids cross-domain traffic in most cases.

This patch, and a corresponding small patch to nginx to use
TCP_REUSPORT_LB_NUMA allows us to serve 190Gb/s of kTLS encrypted
https media content from dual-socket Xeons with only 13% (as
measured by pcm.x) cross domain traffic on the memory controller.

John Baldwin 5ea36d92e6 Support hardware rate limiting (pacing) with TLS offload.
- Add a new send tag type for a send tag that supports both rate
  limiting (packet pacing) and TLS offload (mostly similar to D22669
  but adds a separate structure when allocating the new tag type).

- When allocating a send tag for TLS offload, check to see if the
  connection already has a pacing rate.  If so, allocate a tag that
  supports both rate limiting and TLS offload rather than a plain TLS
  offload tag.

- When setting an initial rate on an existing ifnet KTLS connection,
  set the rate in the TCP control block inp and then reset the TLS
  send tag (via ktls_output_eagain) to reallocate a TLS + ratelimit
  send tag.  This allocates the TLS send tag asynchronously from a
  task queue, so the TLS rate limit tag alloc is always sleepable.

- When modifying a rate on a connection using KTLS, look for a TLS
  send tag.  If the send tag is only a plain TLS send tag, assume we
  failed to allocate a TLS ratelimit tag (either during the
  TCP_TXTLS_ENABLE socket option, or during the send tag reset
  triggered by ktls_output_eagain) and ignore the new rate.  If the
  send tag is a ratelimit TLS send tag, change the rate on the TLS tag
  and leave the inp tag alone.

- Lock the inp lock when setting sb_tls_info for a socket send buffer
  so that the routines in tcp_ratelimit can safely dereference the
  pointer without needing to grab the socket buffer lock.

- Add an IFCAP_TXTLS_RTLMT capability flag and associated
  administrative controls in ifconfig(8).  TLS rate limit tags are
  only allocated if this capability is enabled.  Note that TLS offload
  (whether unlimited or rate limited) always requires IFCAP_TXTLS[46].

Richard Scheffenegger 3f0cc70c13 Add IP(V6)_VLAN_PCP to set 802.1 priority per-flow.
This adds a new IP_PROTO / IPV6_PROTO setsockopt (getsockopt)
option IP(V6)_VLAN_PCP, which can be set to -1 (interface
default), or explicitly to any priority between 0 and 7.

Note that for untagged traffic, explicitly adding a
priority will insert a special 801.1Q vlan header with
vlan ID = 0 to carry the priority setting
