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.

99b14d9f1b remove procfs ctl interface
This interface has no in-tree consumers and has been more or less
non-functional for several releases.

Remove manpage note that the procfs special file 'mem' is grouped to
kmem. This hasn't been true since r81107.

Remove procfs' README file. It is an out of date duplication of the manpage
(quoth the README: "since the bsd kernel is single-processor...").

d61db6be37 Use "build" instead of "all" when building ports modules
"all" in ports currently means "stage the ports", which requires root today,
and brings to light other potential issues, like ENAMETOOLONG with staged
directories (bug 161481, etc).

This fixes buildkernel for me when run as a non-root user, assuming all
of the prerequisites have been installed beforehand and are up-to-date.

ef23481a79 Add support for LinuxKPI tasklets.
Tasklets are implemented using a taskqueue and a small statemachine on
top. The additional statemachine is required to ensure all LinuxKPI
tasklets get serialized. FreeBSD taskqueues do not guarantee
serialisation of its tasks, except when there is only one worker
thread configured.

1e3db1de0c Make the LinuxKPI task struct persistent accross system calls.
A set of helper functions have been added to manage the life of the
LinuxKPI task struct. When an external system call or task is invoked,
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
closely which is a dependency by the code using the LinuxKPI APIs.

Add new dedicated td_lkpi_task field has been added to struct thread
instead of abusing td_retval[1].

Fix some header file inclusions to make LINT kernel build properly

cc5bbcb275 Add USB Mass Storage CTL frontend. This makes it possible
for USB OTG-capable hardware to implement device side of USB
Mass Storage, ie pretend it's a flash drive.  It's configured
in the same way as other CTL frontends, using ctladm(8)
or ctld(8).  Differently from usfs(4), all the configuration
can be done without rebuilding the kernel.

Testing and review is welcome.  Right now I'm still moving,
and I don't have access to my test environment, so I'm somewhat
reluctant to making larger changes to this code; on the other
hand I don't want to let it sit on Phab until my testing setup
is back, because I want to get it into 11.1-RELEASE.

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.

This means that FPU is always initialized and handled when available,
and SSE+ register file and exception are handled when available.  This
makes the kernel FPU code much easier to maintain by the cost of
slight bloat for CPUs older than 25 years.

CPU_DISABLE_CMPXCHG outlived its usefulness, see the removed comment

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.

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.

08167db8d6 Turn on FC-Tape by default in the isp(4) driver.
FC-Tape provides additional link level error recovery, and is
highly recommended for tape devices.  It will only be turned on for
a given target if the target supports it.

Without this setting, we default to whatever FC-Tape setting is in
NVRAM on the card.

This can be overridden by setting the following loader tunable, for
example for isp0:

hint.isp.0.nofctape=1

sys/conf/options:
	Add a new kernel config option, ISP_FCTAPE_OFF, that
	defaults the FC-Tape configuration to off.

sys/dev/isp/isp_pci.c:
	If ISP_FCTAPE_OFF is defined, turn off FC-Tape.  Otherwise,
	turn it on if the card supports it.

share/man/man4/isp.4:
	Add a description of FC-Tape to the isp(4) man page.

	Add descriptions of the fctape and nofctape options, as well as the
	ISP_FCTAPE_OFF kernel configuration option.

	Add the ispfw module and kernel drivers to the suggested
	configurations at the top of the man page so that users are less
	likely to leave it out.  The driver works well with the included
	firmware, but may not work at all with whatever firmware the user
	has flashed on their card.

7f582d6294 newvers.sh: consider as modified SVN mixed revision and other cases
The newvers -R option is intended to include build metadata (e.g. user,
host, time) if the build is from an unmodified VCS tree. For subversion
it considered a trailing 'M' as an indication of a modified tree, and
any other version string as modified.

Also include mixed revision checkouts (e.g. 123:126), switched (123S)
and partial (123P) working copies as modified: the revision number is
insufficient to uniquely determine which source was used for the build.

480f31c214 Add support for encrypted kernel crash dumps.
Changes include modifications in kernel crash dump routines, dumpon(8) and
savecore(8). A new tool called decryptcore(8) was added.

A new DIOCSKERNELDUMP I/O control was added to send a kernel crash dump
configuration in the diocskerneldump_arg structure to the kernel.
The old DIOCSKERNELDUMP I/O control was renamed to DIOCSKERNELDUMP_FREEBSD11 for
backward ABI compatibility.

dumpon(8) generates an one-time random symmetric key and encrypts it using
an RSA public key in capability mode. Currently only AES-256-CBC is supported
but EKCD was designed to implement support for other algorithms in the future.
The public key is chosen using the -k flag. The dumpon rc(8) script can do this
automatically during startup using the dumppubkey rc.conf(5) variable.  Once the
keys are calculated dumpon sends them to the kernel via DIOCSKERNELDUMP I/O
control.

When the kernel receives the DIOCSKERNELDUMP I/O control it generates a random
IV and sets up the key schedule for the specified algorithm. Each time the
kernel tries to write a crash dump to the dump device, the IV is replaced by
a SHA-256 hash of the previous value. This is intended to make a possible
differential cryptanalysis harder since it is possible to write multiple crash
dumps without reboot by repeating the following commands:
# sysctl debug.kdb.enter=1
db> call doadump(0)
db> continue
# savecore

A kernel dump key consists of an algorithm identifier, an IV and an encrypted
symmetric key. The kernel dump key size is included in a kernel dump header.
The size is an unsigned 32-bit integer and it is aligned to a block size.
The header structure has 512 bytes to match the block size so it was required to
make a panic string 4 bytes shorter to add a new field to the header structure.
If the kernel dump key size in the header is nonzero it is assumed that the
kernel dump key is placed after the first header on the dump device and the core
dump is encrypted.

Separate functions were implemented to write the kernel dump header and the
kernel dump key as they need to be unencrypted. The dump_write function encrypts
data if the kernel was compiled with the EKCD option. Encrypted kernel textdumps
are not supported due to the way they are constructed which makes it impossible
to use the CBC mode for encryption. It should be also noted that textdumps don't
contain sensitive data by design as a user decides what information should be
dumped.

savecore(8) writes the kernel dump key to a key.# file if its size in the header
is nonzero. # is the number of the current core dump.

decryptcore(8) decrypts the core dump using a private RSA key and the kernel
dump key. This is performed by a child process in capability mode.
If the decryption was not successful the parent process removes a partially
decrypted core dump.

Description on how to encrypt crash dumps was added to the decryptcore(8),
dumpon(8), rc.conf(5) and savecore(8) manual pages.

EKCD was tested on amd64 using bhyve and i386, mipsel and sparc64 using QEMU.
The feature still has to be tested on arm and arm64 as it wasn't possible to run
FreeBSD due to the problems with QEMU emulation and lack of hardware.

77cb4d3e50 bhnd(4): Unify NVRAM/SPROM parsing, implement compact SPROM layout encoding.
- Defined an abstract NVRAM I/O API (bhnd_nvram_io), decoupling NVRAM/SPROM
  parsing from the actual underlying NVRAM data provider (e.g. CFE firmware
  devices).
- Defined an abstract NVRAM data API (bhnd_nvram_data), decoupling
  higher-level NVRAM operations (indexed lookup, data conversion, etc) from
  the underlying NVRAM file format parsing/serialization.
- Implemented a new high-level bhnd_nvram_store API, providing indexed
  variable lookup, pending write tracking, etc on top of an arbitrary
  bhnd_nvram_data instance.
- Migrated all bhnd(4) NVRAM device drivers to the common bhnd_nvram_store
  API.
- Implemented a common bhnd_nvram_val API for parsing/encoding NVRAM
  variable values, including applying format-specific behavior when
  converting to/from the NVRAM string representations.
- Dropped the now unnecessary bhnd_nvram driver, and moved the
  broadcom/mips-specific CFE NVRAM driver out into sys/mips/broadcom.
- Implemented a new nvram_map file format:
        - Variable definitions are now defined separately from the SPROM
          layout. This will also allow us to define CIS tuple NVRAM
          mappings referencing the common NVRAM variable definitions.
        - Variables can now be defined within arbitrary named groups.
        - Textual descriptions and help information can be defined inline
          for both variables and variable groups.
        - Implemented a new, compact encoding of SPROM image layout
          offsets.
- Source-level (but not build system) support for building the NVRAM file
  format APIs (bhnd_nvram_io, bhnd_nvram_data, bhnd_nvram_store) as a
  userspace library.

The new compact SPROM image layout encoding is loosely modeled on Apple
dyld compressed LINKEDIT symbol binding opcodes; it provides a compact
state-machine encoding of the mapping between NVRAM variables and the SPROM
image offset, mask, and shift instructions necessary to decode or encode
the SPROM variable data.

The compact encoding reduces the size of the generated SPROM layout data
from roughly 60KB to 3KB. The sequential nature SPROM layout opcode tables
also simplify iteration of the SPROM variables, as it's no longer
neccessary to iterate the full NVRAM variable definition table, but
instead simply scan the SPROM revision's layout opcode table.

871c968b3a hyperv/pcib: enable PCIe pass-through (a.k.a. Discrete Device Assignment)
The feature enables us to pass through physical PCIe devices to FreeBSD VM
running on Hyper-V (Windows Server 2016) to get near-native performance with
low CPU utilization.

The patch implements a PCI bridge driver to support the feature:

1) The pcib driver talks to the host to discover device(s) and presents
the device(s) to FreeBSD's pci driver via PCI configuration space (note:
to access the configuration space, we don't use the standard I/O port
0xCF8/CFC method; instead, we use an MMIO-based method supplied by Hyper-V,
which is very similar to the 0xCF8/CFC method).

2) The pcib driver allocates resources for the device(s) and initialize
the related BARs, when the device driver's attach method is invoked;

3) The pcib driver talks to the host to create MSI/MSI-X interrupt
remapping between the guest and the host;

4) The pcib driver supports device hot add/remove.

168fce73b5 hyperv/vss: Add driver and tools for VSS
VSS stands for "Volume Shadow Copy Service".  Unlike virtual machine
snapshot, it only takes snapshot for the virtual disks, so both
filesystem and applications have to aware of it, and cooperate the
whole VSS process.

This driver exposes two device files to the userland:

    /dev/hv_fsvss_dev

    Normally userland programs should _not_ mess with this device file.
    It is currently used by the hv_vss_daemon(8), which freezes and
    thaws the filesystem.  NOTE: currently only UFS is supported, if
    the system mounts _any_ other filesystems, the hv_vss_daemon(8)
    will veto the VSS process.

    If hv_vss_daemon(8) was disabled, then this device file must be
    opened, and proper ioctls must be issued to keep the VSS working.

    /dev/hv_appvss_dev

    Userland application can opened this device file to receive the
    VSS freeze notification, hold the VSS for a while (mainly to flush
    application data to filesystem), release the VSS process, and
    receive the VSS thaw notification i.e. applications can run again.

    The VSS will still work, even if this device file is not opened.
    However, only filesystem consistency is promised, if this device
    file is not opened or is not operated properly.

hv_vss_daemon(8) is started by devd(8) by default.  It can be disabled
by editting /etc/devd/hyperv.conf.

where N is 1, 2, and 3. Pins in each bank are pre-named to match names
on boards schematics: GPIO_S0_SCnn, GPIO_S0_NCnn, and GPIO_S5_nn.

Controller supports edge-triggered and level-triggered interrupts but
current version of the driver does not have interrupts support

eecaab5275 Merge i.MX and PowerPC SDHCI drivers
Summary:
i.MX5 and PowerPC use a very similar eSDHC controller, which is also
similar to the uSDHC controller used by i.MX6.  The imx_sdhci driver works
almost completely with PowerPC, with some minor tweaks.

There is one caveat with this: reset currently does not work on PowerPC, so has
been #ifdef'd out until this can be tracked down and fixed.  If resets are done
the controller will timeout all data transactions.  Without a reset, it appears
to work just fine.

This is part 3, following up r308186 and r308187.

Test Plan:
This has been tested on a PowerPC QorIQ P1022 board.  It has not been
tested on i.MX, but no regressions are expected.

Upstream the BUF_TRACKING and FULL_BUF_TRACKING buffer debugging code.
This can be handy in tracking down what code touched hung bios and bufs
last. The full history is especially useful, but adds enough bloat that
it shouldn't be enabled in release builds.

Function names (or arbitrary string constants) are tracked in a

448897d366 add iic interface to ig4 driver, move isl and cyapa to iicbus
Summary:
The hardware does not expose a classic SMBus interface.
Instead it has a lower level interface that can express a far richer
I2C protocol than what smbus offers.  However, the interface does not
provide a way to explicitly generate the I2C stop and start conditions.
It's only possible to request that the stop condition is generated
after transferring the next byte in either direction.  So, at least
one data byte must always be transferred.
Thus, some I2C sequences are impossible to generate, e.g., an equivalent
of smbus quick command (<start>-<slave addr>-<r/w bit>-<stop>).

At the same time isl(4) and cyapa(4) are moved to iicbus and now they use
iicbus_transfer for communication.  Previously they used smbus_trans()
interface that is not defined by the SMBus protocol and was implemented
only by ig4(4).  In fact, that interface was impossible to implement
for the typical SMBus controllers like intpm(4) or ichsmb(4) where
a type of the SMBus command must be programmed.

The plan is to remove smbus_trans() and all its uses.
As an aside, the smbus_trans() method deviates from the standard,
but perhaps backwards, FreeBSD convention of using 8-bit slave
addresses (shifted by 1 bit to the left).  The method expects
7-bit addresses.

There is a user facing consequence of this change.
A user must now provide device hints for isl and cyapa that specify an iicbus to use
and a slave address on it.
On Chromebook hardware where isl and cyapa devices are commonly found
it is also possible to use a new chromebook_platform(4) driver that
automatically configures isl and cyapa devices.  There is no need to
provide the device hints in that case,

Right now smbus(4) driver tries to discover all slaves on the bus.
That is very dangerous.  Fortunately, the probing code uses smbus_trans()
to do its job, so it is really enabled for ig4 only.
The plan is to remove that auto-probing code and smbus_trans().

dc9b124d66 Create a new MACHINE_ARCH for Freescale PowerPC e500v2
Summary:
The Freescale e500v2 PowerPC core does not use a standard FPU.
Instead, it uses a Signal Processing Engine (SPE)--a DSP-style vector processor
unit, which doubles as a FPU.  The PowerPC SPE ABI is incompatible with the
stock powerpc ABI, so a new MACHINE_ARCH was created to deal with this.
Additionaly, the SPE opcodes overlap with Altivec, so these are mutually
exclusive.  Taking advantage of this fact, a new file, powerpc/booke/spe.c, was
created with the same function set as in powerpc/powerpc/altivec.c, so it
becomes effectively a drop-in replacement.  setjmp/longjmp were modified to save
the upper 32-bits of the now-64-bit GPRs (upper 32-bits are only accessible by
the SPE).

Note: This does _not_ support the SPE in the e500v1, as the e500v1 SPE does not
support double-precision floating point.

Also, without a new MACHINE_ARCH it would be impossible to provide binary
packages which utilize the SPE.

Additionally, no work has been done to support ports, work is needed for this.
This also means no newer gcc can yet be used.  However, gcc's powerpc support
has been refactored which would make adding a powerpcspe-freebsd target very
easy.

Test Plan:
This was lightly tested on a RouterBoard RB800 and an AmigaOne A1222
(P1022-based) board, compiled against the new ABI.  Base system utilities
(/bin/sh, /bin/ls, etc) still function appropriately, the system is able to boot
multiuser.

bd79708dbf In the TCP stack, the hhook(9) framework provides hooks for kernel modules
to add actions that run when a TCP frame is sent or received on a TCP
session in the ESTABLISHED state. In the base tree, this functionality is
only used for the h_ertt module, which is used by the cc_cdg, cc_chd, cc_hd,
and cc_vegas congestion control modules.

Presently, we incur overhead to check for hooks each time a TCP frame is
sent or received on an ESTABLISHED TCP session.

This change adds a new compile-time option (TCP_HHOOK) to determine whether
to include the hhook(9) framework for TCP. To retain backwards
compatibility, I added the TCP_HHOOK option to every configuration file that
already defined "options INET". (Therefore, this patch introduces no
functional change. In order to see a functional difference, you need to
compile a custom kernel without the TCP_HHOOK option.) This change will
allow users to easily exclude this functionality from their kernel, should
they wish to do so.

Note that any users who use a custom kernel configuration and use one of the
congestion control modules listed above will need to add the TCP_HHOOK
option to their kernel configuration.

bc3ad3a179 Add kernel interfaces to call EFI Runtime Services.
Runtime services require special execution environment for the call.
Besides that, OS must inform firmware about runtime virtual memory map
which will be active during the calls, with the SetVirtualAddressMap()
runtime call, done while the 1:1 mapping is still used.  There are two
complication: the SetVirtualAddressMap() effectively must be done from
loader, which needs to know kernel address map in advance.  More,
despite not explicitely mentioned in the specification, both 1:1 and
the map passed to SetVirtualAddressMap() must be active during the
SetVirtualAddressMap() call.  Second, there are buggy BIOSes which
require both mappings active during runtime calls as well, most likely
because they fail to identify all relocations to perform.

On amd64, we can get rid of both problems by providing 1:1 mapping for
the duration of runtime calls, by temprorary remapping user addresses.
As result, we avoid the need for loader to know about future kernel
address map, and avoid bugs in BIOSes.  Typically BIOS only maps
something in low 4G.  If not runtime bugs, we would take advantage of
the DMAP, as previous versions of this patch did.

Similar but more complicated trick can be used even for i386 and 32bit
runtime, if and when the EFI boot on i386 is supported.  We would need
a trampoline page, since potentially whole 4G of VA would be switched
on calls, instead of only userspace portion on amd64.

Context switches are disabled for the duration of the call, FPU access
is granted, and interrupts are not disabled.  The later is possible
because kernel is mapped during calls.

To test, the sysctl mib debug.efi_time is provided, setting it to 1
makes one call to EFI get_time() runtime service, on success the efitm
structure is printed to the control terminal.  Load efirt.ko, or add
EFIRT option to the kernel config, to enable code.

5e7b54b184 Add very preliminary support for CloudABI for ARMv6.
In order to make CloudABI work on ARMv6, start off by copying over the
sysvec for ARM64 and adjust it to use 32-bit registers. Also add code
for fetching arguments from the stack if needed, as there are fewer
register than on ARM64.

Also import the vDSO that is needed to invoke system calls. This vDSO
uses the intra procedure call register (ip) to store the system call
number. This is a bit simpler than what native FreeBSD does, as FreeBSD
uses r7, while preserving the original r7 into ip.

This sysvec seems to be complete enough to start CloudABI processes.
These processes are capable of linking in the vDSO and are therefore
capable of executing (most?) system calls successfully. Unfortunately,
the biggest show stopper is still that TLS is completely broken:

- The linker used by CloudABI, LLD, still has troubles with some of the
  relocations needed for TLS. See LLVM bug 30218 for more details.

- Whereas FreeBSD uses the tpidruro register for TLS, for CloudABI I
  want to make use of tpidrurw, so that userspace can modify the base
  address directly. This is needed for efficient emulation.
  Unfortunately, this register doesn't seem to be preserved across
  context switches yet.

6af45170c1 Chelsio T4/T5 VF driver.
The cxgbev/cxlv driver supports Virtual Function devices for Chelsio
T4 and T4 adapters.  The VF devices share most of their code with the
existing PF4 driver (cxgbe/cxl) and as such the VF device driver
currently depends on the PF4 driver.

Similar to the cxgbe/cxl drivers, the VF driver includes a t4vf/t5vf
PCI device driver that attaches to the VF device.  It then creates
child cxgbev/cxlv devices representing ports assigned to the VF.
By default, the PF driver assigns a single port to each VF.

t4vf_hw.c contains VF-specific routines from the shared code used to
fetch VF-specific parameters from the firmware.

t4_vf.c contains the VF-specific PCI device driver and includes its
own attach routine.

VF devices are required to use a different firmware request when
transmitting packets (which in turn requires a different CPL message
to encapsulate messages).  This alternate firmware request does not
permit chaining multiple packets in a single message, so each packet
results in a firmware request.  In addition, the different CPL message
requires more detailed information when enabling hardware checksums,
so parse_pkt() on VF devices must examine L2 and L3 headers for all
packets (not just TSO packets) for VF devices.  Finally, L2 checksums
on non-UDP/non-TCP packets do not work reliably (the firmware trashes
the IPv4 fragment field), so IPv4 checksums for such packets are
calculated in software.

Most of the other changes in the non-VF-specific code are to expose
various variables and functions private to the PF driver so that they
can be used by the VF driver.

Note that a limited subset of cxgbetool functions are supported on VF
devices including register dumps, scheduler classes, and clearing of
statistics.  In addition, TOE is not supported on VF devices, only for
the PF interfaces.

664a749708 Implement a generic bhnd(4) device enumeration table API.
This defines a new bhnd_erom_if API, providing a common interface to device
enumeration on siba(4) and bcma(4) devices, for use both in the bhndb bridge
and SoC early boot contexts, and migrates mips/broadcom over to the new API.

This also replaces the previous adhoc device enumeration support implemented
for mips/broadcom.

Migration of bhndb to the new API will be implemented in a follow-up commit.


- Defined new bhnd_erom_if interface for bhnd(4) device enumeration, along
  with bcma(4) and siba(4)-specific implementations.
- Fixed a minor bug in bhndb that logged an error when we attempted to map the
  full siba(4) bus space (18000000-17FFFFFF) in the siba EROM parser.
- Reverted use of the resource's start address as the ChipCommon enum_addr in
  bhnd_read_chipid(). When called from bhndb, this address is found within the
  host address space, resulting in an invalid bridged enum_addr.
- Added support for falling back on standard bus_activate_resource() in
  bhnd_bus_generic_activate_resource(), enabling allocation of the bhnd_erom's
  bhnd_resource directly from a nexus-attached bhnd(4) device.
- Removed BHND_BUS_GET_CORE_TABLE(); it has been replaced by the erom API.
- Added support for statically initializing bhnd_erom instances, for use prior
  to malloc availability. The statically allocated buffer size is verified both
  at runtime, and via a compile-time assertion (see BHND_EROM_STATIC_BYTES).
- bhnd_erom classes are registered within a module via a linker set, allowing
  mips/broadcom to probe available EROM parser instances without creating a
  strong reference to bcma/siba-specific symbols.
- Migrated mips/broadcom to bhnd_erom_if, replacing the previous MIPS-specific
  device enumeration implementation.

dbbaf04f1e Remove support for idle page zeroing.
Idle page zeroing has been disabled by default on all architectures since
r170816 and has some bugs that make it seemingly unusable. Specifically,
the idle-priority pagezero thread exacerbates contention for the free page
lock, and yields the CPU without releasing it in non-preemptive kernels. The
pagezero thread also does not behave correctly when superpage reservations
are enabled: its target is a function of v_free_count, which includes
reserved-but-free pages, but it is only able to zero pages belonging to the

22f2f875ad Make execution of 32-bit CloudABI executables work on amd64.
A nice thing about requiring a vDSO is that it makes it incredibly easy
to provide full support for running 32-bit processes on 64-bit systems.
Instead of letting the kernel be responsible for composing/decomposing
64-bit arguments across multiple registers/stack slots, all of this can
now be done in the vDSO. This means that there is no need to provide
duplicate copies of certain system calls, like the sys_lseek() and
freebsd32_lseek() we have for COMPAT_FREEBSD32.

This change imports a new vDSO from the CloudABI repository that has
automatically generated code in it that copies system call arguments
into a buffer, padding them to eight bytes and zero-extending any
pointers/size_t arguments. After returning from the kernel, it does the
inverse: extracting return values, in the process truncating
pointers/size_t values to 32 bits.

c30c436a58 FAST_DEPEND: Fix 'make all install' not properly rebuilding based on .depend.* files.
An optimization is in place to skip reading the .depend.* files with
'make install'.  This was too strong and broke 'make all install' and
'make foo.o foo install'.  Now only skip reading the dependency files
if all make targets ran are install targets.

The problem comes about because headers are only added in as a guessed
dependency if .depend.* files do not yet exist.  If they do exist, even
if being skipped from being read, then the header dependencies are not
applied.  This applies to all #included files, and not just headers.

Copy over amd64's cloudabi64_sysvec.c into i386 and tailor it to work.
Again, we use a system call convention similar to FreeBSD, except that
there is no support for indirect system calls (%eax == 0).

Where i386 differs from amd64 is that we have to store thread/process
entry arguments on the stack instead of using registers. We also have to
put an extra pointer on the stack for TLS (for GSBASE). Place that
pointer in the empty slot that is normally used to hold return
addresses. That seems to keep the code simple.

7ce0716103 Rewrite the vDSOs for CloudABI in assembly.
The reason why the old vDSOs were written in C using inline assembly was
purely because they were embedded in the C library directly as static
inline functions. This was practical during development, because it
meant you could invoke system calls without any library dependencies.
The vDSO was simply a copy of these functions.

Now that we require the use of the vDSO, there is no longer any need for
embedding them in C code directly. Rewriting them in assembly has the
advantage that they are closer to ideal (less useless branching, less
assumptions about registers remaining unclobbered by the kernel, etc).
They are also easier to build, as they no longer depend on the C type
information for CloudABI.

Stateless NAT64 registers external action with name nat64stl. This
keyword should be used to create NAT64 instance and to address this
instance in rules. Stateless NAT64 uses two lookup tables with mapped
IPv4->IPv6 and IPv6->IPv4 addresses to perform translation.

A configuration of instance should looks like this:
 1. Create lookup tables:
 # ipfw table T46 create type addr valtype ipv6
 # ipfw table T64 create type addr valtype ipv4
 2. Fill T46 and T64 tables.
 3. Add rule to allow neighbor solicitation and advertisement:
 # ipfw add allow icmp6 from any to any icmp6types 135,136
 4. Create NAT64 instance:
 # ipfw nat64stl NAT create table4 T46 table6 T64
 5. Add rules that matches the traffic:
 # ipfw add nat64stl NAT ip from any to table(T46)
 # ipfw add nat64stl NAT ip from table(T64) to 64:ff9b::/96
 6. Configure DNS64 for IPv6 clients and add route to 64:ff9b::/96
    via NAT64 host.

Stateful NAT64 registers external action with name nat64lsn. The only
one option required to create nat64lsn instance - prefix4. It defines
the pool of IPv4 addresses used for translation.

A configuration of instance should looks like this:
 1. Add rule to allow neighbor solicitation and advertisement:
 # ipfw add allow icmp6 from any to any icmp6types 135,136
 2. Create NAT64 instance:
 # ipfw nat64lsn NAT create prefix4 A.B.C.D/28
 3. Add rules that matches the traffic:
 # ipfw add nat64lsn NAT ip from any to A.B.C.D/28
 # ipfw add nat64lsn NAT ip6 from any to 64:ff9b::/96

  to remove it.
  We now use BBL (Berkeley Boot Loader) -- standard RISC-V firmware,
  which provides operation in machine mode for us.
  We now use standard SBI calls to machine mode, instead of handmade
  'syscalls'.
o Remove HTIF bus.
  HTIF bus is now legacy and no longer exists in RISC-V specification.
  HTIF code still exists in Spike simulator, but BBL do not provide
  raw interface to it.
  Memory disk is only choice for now to have multiuser booted in Spike,
  until Spike has implemented more devices (e.g. Virtio, etc).

0ce1624d0e Move IPv4-specific jail functions to new file netinet/in_jail.c
_prison_check_ip4 renamed to prison_check_ip4_locked

Move IPv6-specific jail functions to new file netinet6/in6_jail.c
_prison_check_ip6 renamed to prison_check_ip6_locked

Add appropriate prototypes to sys/sys/jail.h

Adjust kern_jail.c to call prison_check_ip4_locked and
prison_check_ip6_locked accordingly.

Add netinet/in_jail.c and netinet6/in6_jail.c to the list of files that
need to be built when INET and INET6, respectively, are configured in the
kernel configuration file.

fa03524a9f Merge i386 and amd64 variants of mp_watchdog.c into x86/, there is no
difference between files.
For pc98, put x86/mp_x86.c into the same place as used by i386 file list.
Fix typo in comment.

6cedae09a2 Merge MPC85XX and QorIQ config options
Summary:
MPC85XX and QorIQ are very similar.  When the DPAA dTSEC driver was
added, QORIQ_DPAA was brought in as a config option to support the differences
in hardware register settings between QorIQ (e500mc-, e5500- based) SoCs and
QUICC (e500v1/e500v2-based) SoCs, particularly in the Local Access Window (LAW)
target settings.

Unify these settings using macros to hide details and ease porting, and use a
new function (mpc85xx_is_qoriq()) to distinguish between QorIQ and QUICC SoCs at
runtime.

An alternative to using the function could be to use a variable initialized at
platform attach time, which may incur less overhead at runtime.  Since it's not
in the critical path once booted, this optimization doesn't seem necessary at
first pass.
