27cb8d849f Garbage collect unused chacha20 code
Two copies of chacha20 were imported into the tree on Apr 15 2017 (r316982)
and Apr 16 2017 (r317015).  Only the latter is actually used by anything, so
just go ahead and garbage collect the unused version while it's still only
in CURRENT.

I'm not making any judgement on which implementation is better.  If I pulled
the wrong one, feel free to swap the existing implementation out and replace
it with the other code (conforming to the API that actually gets used in
randomdev, of course).  We only need one generic implementation.

e808190a59 Add kernel and userspace code to dump the firmware state of supported
ConnectX-4/5 devices in mlx5core.

The dump is obtained by reading a predefined register map from the
non-destructive crspace, accessible by the vendor-specific PCIe
capability (VSC). The dump is stored in preallocated kernel memory and
managed by the mlx5tool(8), which communicates with the driver using a
character device node.

The utility allows to store the dump in format
    <address> <value>
into a file, to reset the dump content, and to manually initiate the
dump.

A call to mlx5_fwdump() should be added at the places where a dump
must be fetched automatically. The most likely place is right before a
firmware reset request.

This provides much smoother and more responsive page daemon output, anticipating

064827be34 MFV r329799, r329800:
9079 race condition in starting and ending condesing thread for indirect vdevs

illumos/illumos-gate@667ec66f1b

The timeline of the race condition is the following:
[1] Thread A is about to finish condesing the first vdev in spa_condense_indirect_thread(),
so it calls the spa_condense_indirect_complete_sync() sync task which sets the
spa_condensing_indirect field to NULL. Waiting for the sync task to finish, thread A
sleeps until the txg is done. When this happens, thread A will acquire spa_async_lock
and set spa_condense_thread to NULL.
[2] While thread A waits for the txg to finish, thread B which is running spa_sync() checks
whether it should condense the second vdev in vdev_indirect_should_condense() by checking
the spa_condensing_indirect field which was set to NULL by spa_condense_indirect_thread()
from thread A. So it goes on and tries to spawn a new condensing thread in
spa_condense_indirect_start_sync() and the aforementioned assertions fails because thread A
has not set spa_condense_thread to NULL (which is basically the last thing it does before
returning).

The main issue here is that we rely on both spa_condensing_indirect and spa_condense_thread to
signify whether a condensing thread is running. Ideally we would only use one throughout the
codebase. In addition, for managing spa_condense_thread we currently use spa_async_lock which
basically tights condensing to scrubing when it comes to pausing and resuming those actions
during spa export.

24433f00ea MFV r329502: 7614 zfs device evacuation/removal
illumos/illumos-gate@5cabbc6b49

https://www.illumos.org/issues/7614:
This project allows top-level vdevs to be removed from the storage pool with
“zpool remove”, reducing the total amount of storage in the pool. This
operation copies all allocated regions of the device to be removed onto other
devices, recording the mapping from old to new location. After the removal is
complete, read and free operations to the removed (now “indirect”) vdev must
be remapped and performed at the new location on disk. The indirect mapping
table is kept in memory whenever the pool is loaded, so there is minimal
performance overhead when doing operations on the indirect vdev.

The size of the in-memory mapping table will be reduced when its entries
become “obsolete” because they are no longer used by any block pointers in
the pool. An entry becomes obsolete when all the blocks that use it are
freed. An entry can also become obsolete when all the snapshots that
reference it are deleted, and the block pointers that reference it have been
“remapped” in all filesystems/zvols (and clones). Whenever an indirect block
is written, all the block pointers in it will be “remapped” to their new
(concrete) locations if possible. This process can be accelerated by using
the “zfs remap” command to proactively rewrite all indirect blocks that
reference indirect (removed) vdevs.

Note that when a device is removed, we do not verify the checksum of the data
that is copied. This makes the process much faster, but if it were used on
redundant vdevs (i.e. mirror or raidz vdevs), it would be possible to copy
the wrong data, when we have the correct data on e.g. the other side of the
mirror. Therefore, mirror and raidz devices can not be removed.

6026dcd7ca Add support for zstd-compressed user and kernel core dumps.
This works similarly to the existing gzip compression support, but
zstd is typically faster and gives better compression ratios.

Support for this functionality must be configured by adding ZSTDIO to
one's kernel configuration file. dumpon(8)'s new -Z option is used to
configure zstd compression for kernel dumps. savecore(8) now recognizes
and saves zstd-compressed kernel dumps with a .zst extension.

90a48fba23 After r328426, g_label depends on UFS (option FFS) code to read UFS
superblock, and the kernel will fail to link when UFS is not built
in.  This commit makes it depend on a small portion of FFS bits and
thereby fixes build for this situation.

This is intended as an interim bandaid, and the actual superblock
reading code should probably be made independent of UFS, so we do
not need to depend on it (see kib@'s comment in the review for
details), and we will revisit this once the superblock check hashes
are all in place.

78f57a9cde Generalize the gzio API.
We currently use a set of subroutines in kern_gzio.c to perform
compression of user and kernel core dumps. In the interest of adding
support for other compression algorithms (zstd) in this role without
complicating the API consumers, add a simple compressor API which can be
used to select an algorithm.

Also change the (non-default) GZIO kernel option to not enable
compressed user cores by default. It's not clear that such a default
would be desirable with support for multiple algorithms implemented,
and it's inconsistent in that it isn't applied to kernel dumps.

8d14ca9c99 Introduce bwn(4) support for the bhnd(4) bus.
Currently, bwn(4) relies on the siba_bwn(4) bus driver to provide support
for the on-chip SSB interconnect found in Broadcom's older PCI(e) Wi-Fi
adapters. Non-PCI Wi-Fi adapters, as well as the newer BCMA interconnect
found in post-2009 Broadcom Wi-Fi hardware, are not supported by
siba_bwn(4).

The bhnd(4) bus driver (also used by the FreeBSD/MIPS Broadcom port)
provides a unified kernel interface to a superset of the hardware supported
by siba_bwn; by attaching bwn(4) via bhnd(4), we can support both modern
PCI(e) Wi-Fi devices based on the BCMA backplane interconnect, as well as
Broadcom MIPS WiSoCs that include a D11 MAC core directly attached to their
SSB or BCMA backplane.

This diff introduces opt-in bwn(4) support for bhnd(4) by providing:

 - A small bwn(4) driver subclass, if_bwn_bhnd, that attaches via
   bhnd(4) instead of siba_bwn(4).
 - A bhndb(4)-based PCI host bridge driver, if_bwn_pci, that optionally
   probes at a higher priority than the siba_bwn(4) PCI driver.
 - A set of compatibility shims that perform translation of bwn(4)'s
   siba_bwn function calls into their bhnd(9) API equivalents when bwn(4)
   is attached via a bhnd(4) bus parent. When bwn(4) is attached via
   siba_bwn(4), all siba_bwn function calls are simply passed through to
   their original implementations.

To test bwn(4) with bhnd(4), place the following lines in loader.conf(5):

  hw.bwn_pci.preferred="1"

  if_bwn_pci_load="YES
  bwn_v4_ucode_load="YES"
  bwn_v4_lp_ucode_load="YES"

To verify that bwn(4) is using bhnd(4), you can check dmesg:

  bwn0: <Broadcom 802.11 MAC/PHY/Radio, rev 15> ... on bhnd0

... or devinfo(8):

pcib2
  pci2
    bwn_pci0
      bhndb0
        bhnd0
          bwn0
          ...

bwn(4)/bhnd(4) has been tested for regressions with most chipsets currently
supported by bwn(4), including:

  - BCM4312
  - BCM4318
  - BCM4321

With minimal changes to the DMA code (not included in this commit), I was
also able to test support for newer BCMA devices by bringing up basic
working Wi-Fi on two previously unsupported, BCMA-based N-PHY chipsets:

  - BCM43224
  - BCM43225

4e96bf3a37 bhnd(4): extend the PMU APIs to support bwn(4)
The bwn(4) driver requires a number of extensions to the bhnd(4) PMU
interface to support external configuration of PLLs, LDOs, and other
parameters that require chipset or PHY-specific workarounds.

These changes add support for:

- Writing raw voltage register values to PHY-specific LDO regulator
  registers (required by LP-PHY).
- Enabling/disabling PHY-specific LDOs (required by LP-PHY)
- Writing to arbitrary PMU chipctrl registers (required for common PHY PLL
  reset support).
- Requesting chipset/PLL-specific spurious signal avoidance modes.
- Querying clock frequency and latency.

Additionally, rather than updating legacy PWRCTL support to conform to the
new PMU interface:

- PWRCTL API is now provided by a bhnd_pwrctl_if.m interface.
- Since PWRCTL is only found in older SSB-based chipsets, translation from
  bhnd(4) bus APIs to corresponding PWRCTL operations is now handled
  entirely within the siba(4) driver.
- The PWRCTL-specific host bridge clock gating APIs in bhnd_bus_if.m have
  been lifted out into a standalone bhnd_pwrctl_hostb_if.m interface.

714d3ee05b cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0.
Changes since 1.16.26.0 for all three firmwares are listed below.  This
list was obtained from the Release Notes of the Chelsio Unified Wire
v3.5.05 release for Linux.

T6 Firmware
++++++++++++
================================================================================
Version : 1.16.63.0
Date    : 09/29/2017
================================================================================

Fixes
-----

BASE:
- Fixed a fw crash when configured traffic rate limit is less than 10kbps.
- Fixed traffic rate limiting for smaller traffic rate value.

ETH:
- Fixed 40G link failure when interface is toggled.
- Fixed adapter crash when interface is toggled during traffic.
- Fixed 25G link failure when PEER only supports consortium mode autoneg
  for 25G.
- Fixed 100G optics link failure when cable is plugged in after bringing up
  the interface.
- Enable RS FEC as default if speed is 100G.
- Fixed DCBX configuration refresh failure.

OFLD
- Fixed 0B iWARP ingress read failure.
- Fixed iWARP SRQ reuse failure.

FOiSCSI:
- Fixed vlan interface ping failure.
- Fixed target discovery failures.
- Fixed mutual chap login failure.

================================================================================
Version : 1.16.59.0
Date    : 09/05/2017
================================================================================

FIXES
-----

BASE:
- Fixed fw crash caused by MC parity error in SO adapters.
- Generate Timer0Int interrupt if fw crashes due to unaligned access error. Host
  driver must look into PCIE_FW register to see if any fw fatal error has
  encountered. If PCIE_FW doesn't indicate any error then driver must ignore this
  interrupt.
- Fixed receive buffer threshold settings which was resulting in error frames on
  receive side.

ETH:
- Fixed an issue in connection traffic shaping when
  FLOWC_WR->FW_FLOWC_MNEM_SCHEDCLASS is not received in first WR on the connection.
- Fixed link failure when speed is changed from 10G-1G-10G due to incorrect flag
  check.
- Fixed improper LED behaviour for blink test and when traffic is running.
- Removed storage of previous fec settings from fw. Driver needs to pass the user
  settings whenever a new module is plugged in as fw resets these when a module is
  unplugged.

OFLD
- OVS offload: TP cache is flushed periodically to get the accuate filters stats
  (hit count).

ENHANCEMENTS
------------

BASE:
- Ring backbone feature added. New FW_PARAMS_PARAM_DEV_RING_BACKBONE param type
  added to query and enable ring backbone support.
- VNI support added for filtering. New entry_type FW_VI_MAC_TYPE_EXACTMAC_VNI
  added to FW_VI_MAC_CMD.
- Added new API FW_PARAM_PARAM_DEV_MPSBGMAP to read the priority to buffer group
  mapping for the ports.
- FW_PARAMS_PARAM_DEV_TPCHMAP API added to read the port to channel mapping.
- HMA (Host memory access) support added. New FW_HMA_CMD and
  FW_PARAMS_PARAM_DEV_HMA_SIZE added to query and configure the HMA. It
  enables the memfree support (256 connections) for iwarp.
- PTP support enabled.

ETH:
- Added consortium mode 50G support.
- Added the ability to allow only selected speeds to be advertised during auto
  negotiation.
- Increased port capability from 16 to 32 bits to support more speeds.
  FW_PARAMS_PARAM_PFVF_PORT_CAPS32 added to query whether fw supports 16 or 32
  bit port capability.

OFLD:
- RDMA Write with immediate support added (iwarp 2.0 feature)
- FW_TLS_KEYCTX_TX_WR removed and security key management moved to driver.
- 256 offloaded connections support for iwarp on SO adapters.

iSCSI:
- New param FW_PARAMS_PARAM_DEV_PPOD_EDRAM added for iscsi ppod configuration
  in EDRAM (performance improvement).

FOiSCSI:
- iSCSI Command offload target support added.

FOFCoE:
- FCoE support enabled.

https://www.illumos.org/issues/8552
  In the LUA interpreter used by "zfs program", the lua format() function
  accidentally includes support for '%f' and friends, which can cause compilation
  problems when building on platforms that don't support floating-point math in
  the kernel (e.g. sparc). Support for '%f' friends (%f %e %E %g %G) should be
  removed, since there's no way to supply a floating-point value anyway (all

bb2e8108e1 Add a new driver, ds13rtc, that handles all DS13xx series i2c RTC chips.
This driver supports only basic timekeeping functionality.  It completely
replaces the ds133x driver.  It can also replace the ds1374 driver, but that
will take a few other changes in MIPS code and config, and will be committed
separately.  It does NOT replace the existing ds1307 driver, which provides
access to some of the extended features on the 1307 chip, such as controlling
the square wave output signal.  If both ds1307 and ds13rtc drivers are
present, the ds1307 driver will outbid and win control of the device.

This driver can be configured with FDT data, or by using hints on non-FDT
systems.  In addition to the standard hints for i2c devices, it requires
a "chiptype" string of the form "dallas,ds13xx" where 'xx' is the chip id
(i.e., the same format as FDT compat strings).

a94a63f0a6 An MMC/SD/SDIO stack using CAM

flexible queueing will make it easier to write non-storage drivers

userland daemons are possible, though much of that functionality will

Some of the CAM integration isn't complete (there are sleeps in the
device probe state machine, for example), but those minor issues can
be improved in-tree more easily than out of tree and shouldn't gate
progress on other fronts. Appologies to reviews if specific items

f9cdbaba8d MFV r318946: 8021 ARC buf data scatter-ization
illumos/illumos-gate@770499e185
770499e185

https://www.illumos.org/issues/8021
  The ARC buf data project (known simply as "ABD" since its genesis in the ZoL
  community) changes the way the ARC allocates `b_pdata` memory from using linear
  `void *` buffers to using scatter/gather lists of fixed-size 1KB chunks. This
  improves ZFS's performance by helping to defragment the address space occupied
  by the ARC, in particular for cases where compressed ARC is enabled. It could
  also ease future work to allocate pages directly from `segkpm` for minimal-
  overhead memory allocations, bypassing the `kmem` subsystem.
  This is essentially the same change as the one which recently landed in ZFS on
  Linux, although they made some platform-specific changes while adapting this
  work to their codebase:
  1. Implemented the equivalent of the `segkpm` suggestion for future work
  mentioned above to bypass issues that they've had with the Linux kernel memory
  allocator.
  2. Changed the internal representation of the ABD's scatter/gather list so it
  could be used to pass I/O directly into Linux block device drivers. (This
  feature is not available in the illumos block device interface yet.)

FreeBSD notes:
- the actual (default) chunk size is 4KB (despite the text above saying 1KB)
- we can try to reimplement ABDs, so that they are not permanently
  mapped into the KVA unless explicitly requested, especially on
  platforms with scarce KVA
- we can try to use unmapped I/O and avoid intermediate allocation of a
  linear, virtual memory mapped buffer
- we can try to avoid extra data copying by referring to chunks / pages
  in the original ABD

40373cf5b8 Remove msdosfs -o large support.
Its purpose was to translate the values for msdosfs inode numbers,
which is calculated from the msdosfs structures describing the file,
into the range representable by 32bit ino_t.  The translation acted
for filesystems larger than 128Gb, it reserved the range 0xf0000000
(FILENO_FIRST_DYN) to UINT32_MAX and remembered some arbitrary
translation of ino >= FILENO_FIRST_DYN into this range.  It consumed
memory that could be only freed by unmount, and the translation was
not stable across remounts.

With ino_t type extended to 64 bit, there is no such issue and values
can be returned without compaction to 32bit.  That is, for the native
environments, the translation layer is not necessary and adds
significant undeserved code complexity.  For compat ABIs which use
32bit ino_t, the vfs.ino64_trunc_error sysctl provides some measures
to soften the failure mode when inode numbers truncation is not safe.

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

support apparently exist, but we do not currently have support).

With this change, support remains for some netgraph modules that don't

though ng_atmllc certainly stands alone.

This allows those without iscsi(4) support built into the kernel to use

between 10.0-RELEASE and 11.0-RELEASE.

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.

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.

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.

fcf596178b Merge projects/ipsec into head/.
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.
