873ed6f008 linux vdso: pass -fPIC to the assembler, not linker
-fPIC has no effect on linking although it seems to be ignored by
GNU ld.bfd.  However, it causes ld.lld to terminate with an invalid
argument error.

This is equivalent to r296057 but for the kernel (not modules) case.

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

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.

This in turn permits use of external toolchains whose default output

653e7d6396 Split iscsi(4) ctl frontend off of ctl(4) as cfiscsi(4)
The goal of this work is to remove the explicit dependency for ctl(4)
on iscsi(4), so end-users without iscsi(4) support in the kernel can
use ctl(4) for its other functions.

This allows those without iscsi(4) support built into the kernel to use
ctl(4) as a test mechanism. As a sidenote, this was possible around the
10.0-RELEASE period, but made impossible for end-users without iscsi(4)
between 10.0-RELEASE and 11.0-RELEASE.

Automatically load cfiscsi(4) from ctladm(8) and ctld(8) for backwards
compatibility with previously releases. The automatic loading feature is
compiled into the beforementioned tools if MK_ISCSI == yes when building
world.

Add a manpage for cfiscsi(4) and refer to it in ctl(4).

1811d6bf7f Add an experimental DTrace audit provider, which allows users of DTrace to
instrument security event auditing rather than relying on conventional BSM
trail files or audit pipes:

- Add a set of per-event 'commit' probes, which provide access to
  particular auditable events at the time of commit in system-call return.
  These probes gain access to audit data via the in-kernel audit_record
  data structure, providing convenient access to system-call arguments and
  return values in a single probe.

- Add a set of per-event 'bsm' probes, which provide access to particular
  auditable events at the time of BSM record generation in the audit
  worker thread. These probes have access to the in-kernel audit_record
  data structure and BSM representation as would be written to a trail
  file or audit pipe -- i.e., asynchronously in the audit worker thread.

DTrace probe arguments consist of the name of the audit event (to support
future mechanisms of instrumenting multiple events via a single probe --
e.g., using classes), a pointer to the in-kernel audit record, and an
optional pointer to the BSM data and its length. For human convenience,
upper-case audit event names (AUE_...) are converted to lower case in
DTrace.

DTrace scripts can now cause additional audit-based data to be collected
on system calls, and inspect internal and BSM representations of the data.
They do not affect data captured in the audit trail or audit pipes
configured in the system. auditd(8) must be configured and running in
order to provide a database of event information, as well as other audit
configuration parameters (e.g., to capture command-line arguments or
environmental variables) for the provider to operate.

864c28cf81 Use inline asm instead of unportable intrinsics for the SSE4 crc32
optimization.

This fixes building with gcc-4.2.1 (it doesn't support SSE4).
gas-2.17.50 [FreeBSD] supports SSE4 instructions, so this doesn't
need using .byte directives.

This fixes depending on host user headers in the kernel.

Fix user includes (don't depend on namespace pollution in <nmmintrin.h>
that is not included now).

The instrinsics had no advantages except to sometimes avoid compiler
pessimixations.  clang understands them a bit better than inline asm,
and generates better looking code which also runs better for cem, but
for me it just at the same speed or slower by doing excessive
unrollowing in all the wrong places.  gcc-4.2.1 also doesn't understand
what it is doing with unrolling, but with -O3 somehow it does more
unrolling that helps.

Reduce 1 of the the compiler pessimizations (copying a variable which
already satisfies an "rm" constraint in a good way by being in memory
and not used again, to different memory and accessing it there.  Force
copying it to a register instead).

Try to optimize the inner loops significantly, so as to run at full
speed on smaller inputs.  The algorithm is already very MD, and was
tuned for the throughput of 3 crc32 instructions per cycle found on
at least Sandybridge through Haswell.  Now it is even more tuned for
this, so depends more on the compiler not rearranging or unrolling
things too much.  The main inner loop for should have no difficulty
runing at full speed on these CPUs unless the compiler unrolls it too
much.  However, the main inner loop wasn't even used for buffers smaller
than 24K.  Now it is used for buffers larger than 384 bytes.  Now it
is not so long, and the main outer loop is used more.  The new
optimization is to try to arrange that the outer loop runs in parallel
with the next inner loop except for the final iteration; then reduce
the loop sizes significantly to take advantage of this.

72dec0792a - Add support for eMMC "partitions". Besides the user data area, i. e.
the default partition, eMMC v4.41 and later devices can additionally
  provide up to:
  1 enhanced user data area partition
  2 boot partitions
  1 RPMB (Replay Protected Memory Block) partition
  4 general purpose partitions (optionally with a enhanced or extended
    attribute)

  Of these "partitions", only the enhanced user data area one actually
  slices the user data area partition and, thus, gets handled with the
  help of geom_flashmap(4). The other types of partitions have address
  space independent from the default partition and need to be switched
  to via CMD6 (SWITCH), i. e. constitute a set of additional "disks".

  The second kind of these "partitions" doesn't fit that well into the
  design of mmc(4) and mmcsd(4). I've decided to let mmcsd(4) hook all
  of these "partitions" up as disk(9)'s (except for the RPMB partition
  as it didn't seem to make much sense to be able to put a file-system
  there and may require authentication; therefore, RPMB partitions are
  solely accessible via the newly added IOCTL interface currently; see
  also below). This approach for one resulted in cleaner code. Second,
  it retains the notion of mmcsd(4) children corresponding to a single
  physical device each. With the addition of some layering violations,
  it also would have been possible for mmc(4) to add separate mmcsd(4)
  instances with one disk each for all of these "partitions", however.
  Still, both mmc(4) and mmcsd(4) share some common code now e. g. for
  issuing CMD6, which has been factored out into mmc_subr.c.

  Besides simply subdividing eMMC devices, some Intel NUCs having UEFI
  code in the boot partitions etc., another use case for the partition
  support is the activation of pseudo-SLC mode, which manufacturers of
  eMMC chips typically associate with the enhanced user data area and/
  or the enhanced attribute of general purpose partitions.

  CAVEAT EMPTOR: Partitioning eMMC devices is a one-time operation.

- Now that properly issuing CMD6 is crucial (so data isn't written to
  the wrong partition for example), make a step into the direction of
  correctly handling the timeout for these commands in the MMC layer.
  Also, do a SEND_STATUS when CMD6 is invoked with an R1B response as
  recommended by relevant specifications. However, quite some work is
  left to be done in this regard; all other R1B-type commands done by
  the MMC layer also should be followed by a SEND_STATUS (CMD13), the
  erase timeout calculations/handling as documented in specifications
  are entirely ignored so far, the MMC layer doesn't provide timeouts
  applicable up to the bridge drivers and at least sdhci(4) currently
  is hardcoding 1 s as timeout for all command types unconditionally.
  Let alone already available return codes often not being checked in
  the MMC layer ...

- Add an IOCTL interface to mmcsd(4); this is sufficiently compatible
  with Linux so that the GNU mmc-utils can be ported to and used with
  FreeBSD (note that due to the remaining deficiencies outlined above
  SANITIZE operations issued by/with `mmc` currently most likely will
  fail). These latter will be added to ports as sysutils/mmc-utils in
  a bit. Among others, the `mmc` tool of the GNU mmc-utils allows for
  partitioning eMMC devices (tested working).

- For devices following the eMMC specification v4.41 or later, year 0
  is 2013 rather than 1997; so correct this for assembling the device
  ID string properly.

- Let mmcsd.ko depend on mmc.ko. Additionally, bump MMC_VERSION as at
  least for some of the above a matching pair is required.

- In the ACPI front-end of sdhci(4) describe the Intel eMMC and SDXC
  controllers as such in order to match the PCI one.
  Additionally, in the entry for the 80860F14 SDXC controller remove
  the eMMC-only SDHCI_QUIRK_INTEL_POWER_UP_RESET.

ca2ad6bd77 LinuxKPI workqueue cleanup.
This change makes the workqueue implementation behave more like in
Linux, both functionality wise and structure wise.

All workqueue code has been moved to linux_work.c

Add an atomic based statemachine to the work_struct to ensure proper
operation. Prior to this change struct_work was directly mapped to a
FreeBSD task. When a taskqueue has multiple threads the same task may
end up being executed on more than one worker thread simultaneously.
This might cause problems with code coming from Linux, which expects
serial behaviour, similar to Linux tasklets.

Move all global workqueue function names into the linux_xxx domain to
avoid symbol name clashes in the future.

Implement a few more workqueue related functions and macros.

Create two multithreaded taskqueues for the LinuxKPI during module
load, one for time-consuming callbacks and one for non-time consuming
callbacks.

a check is made to create the task struct by demand. A thread
destructor callback is registered to free the task struct when a
thread exits to avoid memory leaks.

This change lays the ground for emulating the Linux kernel more

cb6b8299fd ixl(4): Update to 1.7.12-k
Refresh upstream driver before impending conversion to iflib.

Major new features:

- Support for Fortville-based 25G adapters
- Support for I2C reads/writes

(To prevent getting or sending corrupt data, you should set
dev.ixl.0.debug.disable_fw_link_management=1 when using I2C
[this will disable link!], then set it to 0 when done. The driver implements
the SIOCGI2C ioctl, so ifconfig -v works for reading I2C data,
but there are read_i2c and write_i2c sysctls under the .debug sysctl tree
[the latter being useful for upper page support in QSFP+]).

- Addition of an iWARP client interface (so the future iWARP driver for
  X722 devices can communicate with the base driver).
  - Compiling this option in is enabled by default, with "options IXL_IW" in
    GENERIC.

Small summary
 -------------

o Almost all IPsec releated code was moved into sys/netipsec.
o New kernel modules added: ipsec.ko and tcpmd5.ko. New kernel
  option IPSEC_SUPPORT added. It enables support for loading
  and unloading of ipsec.ko and tcpmd5.ko kernel modules.
o IPSEC_NAT_T option was removed. Now NAT-T support is enabled by
  default. The UDP_ENCAP_ESPINUDP_NON_IKE encapsulation type
  support was removed. Added TCP/UDP checksum handling for
  inbound packets that were decapsulated by transport mode SAs.
  setkey(8) modified to show run-time NAT-T configuration of SA.
o New network pseudo interface if_ipsec(4) added. For now it is
  build as part of ipsec.ko module (or with IPSEC kernel).
  It implements IPsec virtual tunnels to create route-based VPNs.
o The network stack now invokes IPsec functions using special
  methods. The only one header file <netipsec/ipsec_support.h>
  should be included to declare all the needed things to work
  with IPsec.
o All IPsec protocols handlers (ESP/AH/IPCOMP protosw) were removed.
  Now these protocols are handled directly via IPsec methods.
o TCP_SIGNATURE support was reworked to be more close to RFC.
o PF_KEY SADB was reworked:
  - now all security associations stored in the single SPI namespace,
    and all SAs MUST have unique SPI.
  - several hash tables added to speed up lookups in SADB.
  - SADB now uses rmlock to protect access, and concurrent threads
    can do SA lookups in the same time.
  - many PF_KEY message handlers were reworked to reflect changes
    in SADB.
  - SADB_UPDATE message was extended to support new PF_KEY headers:
    SADB_X_EXT_NEW_ADDRESS_SRC and SADB_X_EXT_NEW_ADDRESS_DST. They
    can be used by IKE daemon to change SA addresses.
o ipsecrequest and secpolicy structures were cardinally changed to
  avoid locking protection for ipsecrequest. Now we support
  only limited number (4) of bundled SAs, but they are supported
  for both INET and INET6.
o INPCB security policy cache was introduced. Each PCB now caches
  used security policies to avoid SP lookup for each packet.
o For inbound security policies added the mode, when the kernel does
  check for full history of applied IPsec transforms.
o References counting rules for security policies and security
  associations were changed. The proper SA locking added into xform
  code.
o xform code was also changed. Now it is possible to unregister xforms.
  tdb_xxx structures were changed and renamed to reflect changes in
  SADB/SPDB, and changed rules for locking and refcounting.

 - Enable runtime detection of CPU multiprocessor extensions only
   if SMP_ON_UP option is used. In other cases (pure SMP or UP),
   statically compile only required variant.
 - Don't leak multiprocessor instructions to UP kernel.
 - Correctly handle data cache write back to point of unification.
   DCCMVAU is supported on all armv7 cpus.
 - For SMP_ON_UP kernels, detect proper TTB flags on runtime.

6be2ff7d3e calculate_crc32c: Add SSE4.2 implementation on x86
Derived from an implementation by Mark Adler.

The fast loop performs three simultaneous CRCs over subsets of the data
before composing them.  This takes advantage of certain properties of
the CRC32 implementation in Intel hardware.  (The CRC instruction takes 1
cycle but has 2-3 cycles of latency.)

The CRC32 instruction does not manipulate FPU state.

i386 does not have the crc32q instruction, so avoid it there.  Otherwise
the implementation is identical to amd64.

Add basic userland tests to verify correctness on a variety of inputs.

* Clang now supports -msoft-float, and does not appear to recognize
  "-disable-ppc-float-in-variadic", which appears to have been a crutch until
  soft-float was implemented.  It's now implemented for both 32- and 64-bit.

21b737495b Introduce __read_mostly and __exclusive_cache_line macros.
The intended use is to annotate frequently used globals which either rarely
change (and thus can be grouped in the same cacheline) or are an atomic counter
(which means it may benefit from being the only variable in the cacheline).

Linker script support is provided only for amd64. Architectures without it risk
having other variables put in, i.e. as if they were not annotated. This is
harmless from correctness point of view.

f3e7afe2d7 Implement kernel support for hardware rate limited sockets.
- Add RATELIMIT kernel configuration keyword which must be set to
enable the new functionality.

- Add support for hardware driven, Receive Side Scaling, RSS aware, rate
limited sendqueues and expose the functionality through the already
established SO_MAX_PACING_RATE setsockopt(). The API support rates in
the range from 1 to 4Gbytes/s which are suitable for regular TCP and
UDP streams. The setsockopt(2) manual page has been updated.

- Add rate limit function callback API to "struct ifnet" which supports
the following operations: if_snd_tag_alloc(), if_snd_tag_modify(),
if_snd_tag_query() and if_snd_tag_free().

- Add support to ifconfig to view, set and clear the IFCAP_TXRTLMT
flag, which tells if a network driver supports rate limiting or not.

- This patch also adds support for rate limiting through VLAN and LAGG
intermediate network devices.

- How rate limiting works:

1) The userspace application calls setsockopt() after accepting or
making a new connection to set the rate which is then stored in the
socket structure in the kernel. Later on when packets are transmitted
a check is made in the transmit path for rate changes. A rate change
implies a non-blocking ifp->if_snd_tag_alloc() call will be made to the
destination network interface, which then sets up a custom sendqueue
with the given rate limitation parameter. A "struct m_snd_tag" pointer is
returned which serves as a "snd_tag" hint in the m_pkthdr for the
subsequently transmitted mbufs.

2) When the network driver sees the "m->m_pkthdr.snd_tag" different
from NULL, it will move the packets into a designated rate limited sendqueue
given by the snd_tag pointer. It is up to the individual drivers how the rate
limited traffic will be rate limited.

3) Route changes are detected by the NIC drivers in the ifp->if_transmit()
routine when the ifnet pointer in the incoming snd_tag mismatches the
one of the network interface. The network adapter frees the mbuf and
returns EAGAIN which causes the ip_output() to release and clear the send
tag. Upon next ip_output() a new "snd_tag" will be tried allocated.

4) When the PCB is detached the custom sendqueue will be released by a
non-blocking ifp->if_snd_tag_free() call to the currently bound network
interface.

can be found in several Intel's products starting from PXA family.
Most of implementations have slight differences in behavior and in
addresses for registers subset. This driver covers only BayTrail SoC
implementation for it's the only hardware I have to test it on.

Driver attaches to ACPI bus only and does not have PCI or FDT support
for now due to lack of hardware to test it on.

"intelspi" is the best name I've managed to come up with. Linux driver
name (spi-pxa2xx) does not make sense because current implementation
does not support actual PXA2xx SoCs. And as far as I know there is no
codename assigned to Intel SSP chip.
