9b8d05b8ac Add support for Amazon Elastic Network Adapter (ENA) NIC
ENA is a networking interface designed to make good use of modern CPU
features and system architectures.

The ENA device exposes a lightweight management interface with a
minimal set of memory mapped registers and extendable command set
through an Admin Queue.

The driver supports a range of ENA devices, is link-speed independent
(i.e., the same driver is used for 10GbE, 25GbE, 40GbE, etc.), and has
a negotiated and extendable feature set.

Some ENA devices support SR-IOV. This driver is used for both the
SR-IOV Physical Function (PF) and Virtual Function (VF) devices.

ENA devices enable high speed and low overhead network traffic
processing by providing multiple Tx/Rx queue pairs (the maximum number
is advertised by the device via the Admin Queue), a dedicated MSI-X
interrupt vector per Tx/Rx queue pair, and CPU cacheline optimized
data placement.

The ENA driver supports industry standard TCP/IP offload features such
as checksum offload and TCP transmit segmentation offload (TSO).
Receive-side scaling (RSS) is supported for multi-core scaling.

The ENA driver and its corresponding devices implement health
monitoring mechanisms such as watchdog, enabling the device and driver
to recover in a manner transparent to the application, as well as
debug logs.

Some of the ENA devices support a working mode called Low-latency
Queue (LLQ), which saves several more microseconds. This feature will
be implemented for driver in future releases.

5033c43b7a Add a driver for the Chelsio T6 crypto accelerator engine.
The ccr(4) driver supports use of the crypto accelerator engine on
Chelsio T6 NICs in "lookaside" mode via the opencrypto framework.

Currently, the driver supports AES-CBC, AES-CTR, AES-GCM, and AES-XTS
cipher algorithms as well as the SHA1-HMAC, SHA2-256-HMAC, SHA2-384-HMAC,
and SHA2-512-HMAC authentication algorithms.  The driver also supports
chaining one of AES-CBC, AES-CTR, or AES-XTS with an authentication
algorithm for encrypt-then-authenticate operations.

Note that this driver is still under active development and testing and
may not yet be ready for production use.  It does pass the tests in
tests/sys/opencrypto with the exception that the AES-GCM implementation
in the driver does not yet support requests with a zero byte payload.

To use this driver currently, the "uwire" configuration must be used
along with explicitly enabling support for lookaside crypto capabilities
in the cxgbe(4) driver.  These can be done by setting the following
tunables before loading the cxgbe(4) driver:

    hw.cxgbe.config_file=uwire
    hw.cxgbe.cryptocaps_allowed=-1

64409eeee7 Add basic programmable early warning error injection to the sa(4) driver.
This will help application developers simulate end of tape conditions.

To inject an error in sa0:

sysctl kern.cam.sa.0.inject_eom=1

This will return the next read or write request queued with 0 bytes
written.  Any subsequent writes or reads will go along as usual.

This will also cause the early warning position flag to get set
for the next position query.  So, 'mt status' will show the BPEW
(Beyond Programmable Early Warning) flag on the first query after
an error injection.  After that, the position flags will be as they
are in the underlying tape drive.

Also, update the sa(4) man page to describe tape parameters,
which can be set via 'mt param'.

sys/cam/scsi/scsi_sa.c:
	In saregister(), create the inject_eom sysctl variable.

	In sastart(), check to see whether inject_eom is set.  If
	so, return the read or write with 0 bytes written to
	indicate EOM.  Set the set_pews_status flag so that we
	fake PEWS status in the next position call for reads, and the
	next 3 calls for writes.  This allows the user to see the BPEW
	flag one time via 'mt status'.

	In sagetpos(), check the set_pews_status flag and fake
	PEWS status and decrement the counter if it is set.

share/man/man4/sa.4:
	Document the inject_eom sysctl variable.

	Document all of the parameters currently supported via
	'mt param'.

usr.bin/mt/mt.1:
	Point the user to the sa(4) man page for more details on
	supported parameters.

6953d22b15 Fix error recovery behavior in the pass(4) driver.
After FreeBSD SVN revision 236814, the pass(4) driver changed from
only doing error recovery when the CAM_PASS_ERR_RECOVER flag was
set on a CCB to sometimes doing error recovery if the passed in
retry count was non-zero.

Error recovery would happen if two conditions were met:

1.  The error recovery action was simply a retry.  (Which is most
    cases.)
2.  The retry_count is non-zero. (Which happened a lot because of
    cut-and-pasted code.)

This explains a bug I noticed in with camcontrol:

# camcontrol tur da34 -v
Unit is ready
# camcontrol reset da34
Reset of 1:172:0 was successful

At this point, there should be a Unit Attention:

# camcontrol tur da34 -v
Unit is ready

No Unit Attention.

Try it again:

# camcontrol reset da34
Reset of 1:172:0 was successful

Now set the retry_count to 0 for the TUR:

# camcontrol tur da34 -v -C 0
Unit is not ready
(pass42:mps1:0:172:0): TEST UNIT READY. CDB: 00 00 00 00 00 00
(pass42:mps1:0:172:0): CAM status: SCSI Status Error
(pass42:mps1:0:172:0): SCSI status: Check Condition
(pass42:mps1:0:172:0): SCSI sense: UNIT ATTENTION asc:29,2 (SCSI bus reset occurred)
(pass42:mps1:0:172:0): Field Replaceable Unit: 2

There is the unit attention. camcontrol(8) has a default
retry_count of 1, in case someone sets the -E flag without
setting -C.

The CAM_PASS_ERR_RECOVER behavior was only broken with the
CAMIOCOMMAND ioctl, which is the synchronous pass(4) API.  It has
worked as intended (error recovery is only done when the flag
is set) in the asynchronous API (CAMIOQUEUE ioctl).

sys/cam/scsi/scsi_pass.c:
	In passsendccb(), when calling cam_periph_runccb(), only
	specify the error routine when CAM_PASS_ERR_RECOVER is set.

share/man/man4/pass.4:
	Document that CAM_PASS_ERR_RECOVER is needed to enable
	error recovery.

a7dc31283a Remove the NATM framework including the en(4), fatm(4), hatm(4), and
patm(4) devices.

Maintaining an address family and framework has real costs when we make
infrastructure improvements.  In the case of NATM we support no devices
manufactured in the last 20 years and some will not even work in modern
motherboards (some newer devices that patm(4) could be updated to
support apparently exist, but we do not currently have support).

With this change, support remains for some netgraph modules that don't
require NATM support code. It is unclear if all these should remain,
though ng_atmllc certainly stands alone.

Note well: FreeBSD 11 supports NATM and will continue to do so until at
least September 30, 2021.  Improvements to the code in FreeBSD 11 are
certainly welcome.

e9e768f7e3 bsdgrep: disable GNU_GREP_COMPAT by default
The GNU extension bits in the base system are old, no longer faithful
to upstream, and surprising in some regards. Switch to documenting
WITH_GNU_GREP_COMPAT and default GNU_GREP_COMPAT to OFF in the name of
good behavior.

According to http://www.regular-expressions.info, GNU extensions:

-  Add missing quantifiers to BREs: \?, \+

-  Add branching to BREs: \|

-  Add backreferences (\1 through \9) to EREs

-  Add \w, \W, \s, and \S corresponding to :alnum:, [^[:alnum:]],
   :space:, and [^[:space:]] respectively

-  Add word boundaries and anchors:
   \b: word boundary
   \B: not word boundary
   \<: Strt of word
   \>: End of word
   \`: Start of subject string
    \': End of subject string

These extensions are still available in /usr/bin/grep by default today,
as it is still GNU grep.  As part of the bsdgrep migration plan these
extensions may be added to bsdgrep's regex support if necessary.

3f39ffc893 bsdgrep: add BSD_GREP_FASTMATCH knob for built-in fastmatch
Bugs have been found in the fastmatch implementation as used in bsdgrep.
Some have been fixed (r316495) while fixes for others are in review
(D10098).

In comparison with the fastmatch implementation, Kyle Evans found that:

- regex(3)'s performance with literal expressions offers a speed
  improvement over fastmatch

- regex(3)'s performance, both with simple BREs and EREs, seems to be
  comparable

The regex implementation was imported in r226035, and the commit message
reports:

    This is a temporary solution until the whole regex library is
    not replaced so that BSD grep development can continue and the
    backported code gets some review and testing. This change only
    improves scalability slightly, there is no big performance boost
    yet but several minor bugs have been found and fixed.

Introduce a WITH_/WITHOUT_BSD_GREP_FASTMATCH knob to support testing
of both approaches.
