IPsec RFC6479 support for replay window sizes up to 2^32 - 32 packets.

Since the previous algorithm, based on bit shifting, does not scale
with large replay windows, the algorithm used here is based on
RFC 6479: IPsec Anti-Replay Algorithm without Bit Shifting.
The replay window will be fast to be updated, but will cost as many bits
in RAM as its size.

The previous implementation did not provide a lock on the replay window,
which may lead to replay issues.

MFC r313330:
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.

friend tcp_fields_to_host(). There is third party code that also uses

MFC r313697:
Remove IPsec related PCB code from SCTP.

The inpcb structure has inp_sp pointer that is initialized by
ipsec_init_pcbpolicy() function. This pointer keeps strorage for IPsec
security policies associated with a specific socket.
An application can use IP_IPSEC_POLICY and IPV6_IPSEC_POLICY socket
options to configure these security policies. Then ip[6]_output()
uses inpcb pointer to specify that an outgoing packet is associated
with some socket. And IPSEC_OUTPUT() method can use a security policy
stored in the inp_sp. For inbound packet the protocol-specific input
routine uses IPSEC_CHECK_POLICY() method to check that a packet conforms
to inbound security policy configured in the inpcb.

SCTP protocol doesn't specify inpcb for ip[6]_output() when it sends
packets. Thus IPSEC_OUTPUT() method does not consider such packets as
associated with some socket and can not apply security policies
from inpcb, even if they are configured. Since IPSEC_CHECK_POLICY()
method is called from protocol-specific input routine, it can specify
inpcb pointer and associated with socket inbound policy will be
checked. But there are two problems:
1. Such check is asymmetric, becasue we can not apply security policy
from inpcb for outgoing packet.
2. IPSEC_CHECK_POLICY() expects that caller holds INPCB lock and
access to inp_sp is protected. But for SCTP this is not correct,
becasue SCTP uses own locks to protect inpcb.

To fix these problems remove IPsec related PCB code from SCTP.
This imply that IP_IPSEC_POLICY and IPV6_IPSEC_POLICY socket options
will be not applicable to SCTP sockets. To be able correctly check
inbound security policies for SCTP, mark its protocol header with
the PR_LASTHDR flag.

MFC r314812:
Introduce the concept of IPsec security policies scope.

Currently are defined three scopes: global, ifnet, and pcb.
Generic security policies that IKE daemon can add via PF_KEY interface
or an administrator creates with setkey(8) utility have GLOBAL scope.
Such policies can be applied by the kernel to outgoing packets and checked
agains inbound packets after IPsec processing.
Security policies created by if_ipsec(4) interfaces have IFNET scope.
Such policies are applied to packets that are passed through if_ipsec(4)
interface.
And security policies created by application using setsockopt()
IP_IPSEC_POLICY option have PCB scope. Such policies are applied to
packets related to specific socket. Currently there is no way to list
PCB policies via setkey(8) utility.

Modify setkey(8) and libipsec(3) to be able distinguish the scope of
security policies in the `setkey -DP` listing. Add two optional flags:
'-t' to list only policies related to virtual *tunneling* interfaces,
i.e. policies with IFNET scope, and '-g' to list only policies with GLOBAL
scope. By default policies from all scopes are listed.

To implement this PF_KEY's sadb_x_policy structure was modified.
sadb_x_policy_reserved field is used to pass the policy scope from the
kernel to userland. SADB_SPDDUMP message extended to support filtering
by scope: sadb_msg_satype field is used to specify bit mask of requested
scopes.

For IFNET policies the sadb_x_policy_priority field of struct sadb_x_policy
is used to pass if_ipsec's interface if_index to the userland. For GLOBAL
policies sadb_x_policy_priority is used only to manage order of security
policies in the SPDB. For IFNET policies it is not used, so it can be used
to keep if_index.

After this change the output of `setkey -DP` now looks like:
# setkey -DPt
0.0.0.0/0[any] 0.0.0.0/0[any] any
in ipsec
esp/tunnel/87.250.242.144-87.250.242.145/unique:145

Switch mips busdma to using the common busdma_buffalloc code. This amounts
to copying in some code from the armv4 busdma, and adapting a few variable
and flag names to match the surrounding mips code.

Instead of keeping a local cache of prealloced busdma_map structs on a
mutex-protected list, set up an uma zone to cache them.

Instead of all memory allocations using M_DEVBUF, use new categories
M_BUSDMA for allocations of metadata (tags, maps, segment tracking lists),
and M_BOUNCE for bounce pages.

When buffers are allocated out of the busdma_bufalloc zones the alignment
and size of the buffers is known, and the code can skip doing any "partial
cacheline flush" logic to preserve data that may be adjacent to the DMA
buffer but contain non-DMA data.

Add proper __sync_*() intrinsics for MIPS.

To make <stdatomic.h> work on MIPS (and ARM) using GCC, we need to
provide implementations of the __sync_*() functions. I already added
these functions for 4 and 8 byte types to libcompiler-rt some time ago,
based on top of <machine/atomic.h>.

Unfortunately, <machine/atomic.h> only provides a subset of the features
needed to implement <stdatomic.h>. This means that in some cases we had
to do compare-and-exchange calls in loops, where a simple ll/sc would
suffice.

Also implement these functions for 1 and 2 byte types. MIPS only
provides ll/sc instructions for 4 and 8 byte types, but this is of
course no limitation. We can simply load 4 bytes and use some bitmask
tricks to modify only the bytes affected.

2. New modinfo for loader provided FDT blob.
3. Common x86_init_fdt() called from hammer_time() on amd64 and

4. Split-off FDT specific low-level console functions from FDT

5. Add dev/fdt/fdt_x86.c to hold the fdt_fixup_table[] and the

FDT addresses are I/O ports on x86. Since the core FDT code does
not handle different address spaces, adding support for both I/O
ports and memory addresses requires some thought and discussion.
It may be better to use a compile-time option that controls this.

Implement mechanism to export some kernel timekeeping data to
usermode, using shared page. The structures and functions have vdso
prefix, to indicate the intended location of the code in some future.

The versioned per-algorithm data is exported in the format of struct
vdso_timehands, which mostly repeats the content of in-kernel struct
timehands. Usermode reading of the structure can be lockless.
Compatibility export for 32bit processes on 64bit host is also
provided. Kernel also provides usermode with indication about
currently used timecounter, so that libc can fall back to syscall if
configured timecounter is unknown to usermode code.

The shared data updates are initiated both from the tc_windup(), where
a fast task is queued to do the update, and from sysctl handlers which
change timecounter. A manual override switch
kern.timecounter.fast_gettime allows to turn off the mechanism.

Only x86 architectures export the real algorithm data, and there, only
for tsc timecounter. HPET counters page could be exported as well, but
I prefer to not further glue the kernel and libc ABI there until
proper vdso-based solution is developed.

Minimal stubs neccessary for non-x86 architectures to still compile
are provided.

ABIs use a 64-bit time_t.
o) Because time{spec,val}32 has the same size and layout as time{spec,val} on MIPS
with 32-bit compatibility, then, disable some code which assumes otherwise
wrongly when built for MIPS. A more general macro to check in this case would
seem like a good idea eventually. If someone adds support for using n32
userland with n64 kernels on MIPS, then they will have to add a variety of
flags related to each piece of the ABI that can vary. That's probably the
right time to generalize further.
o) Add MIPS to the list of architectures which use PAD64_REQUIRED in the

we assume that there is no FPU, because majority of SoC does
not have it.

Use FreeBSD/arm approach for handling bus space access: space tag is a pointer
to bus_space structure that defines access methods and hence every bus can
define own accessors. Default space is mips_bus_space_generic. It's a simple
interface to physical memory, values are read with regard to host system
byte order.

- Move Silicon Backplanes code out to system-wide level (dev/siba) as
it's going to be used not only for siba5 devices.

Add memmove() to the kernel, making the kernel compile with Clang.

When copying big structures, LLVM generates calls to memmove(), because
it may not be able to figure out whether structures overlap. This caused
linker errors to occur. memmove() is now implemented using bcopy().
Ideally it would be the other way around, but that can be solved in the
future. On ARM we don't do add anything, because it already has
memmove().

Switch to ath hal source code. Note this removes the ath_hal
module; the ath module now brings in the hal support. Kernel
config files are almost backwards compatible; supplying

device ath_hal

gives you the same chip support that the binary hal did but you
must also include

options AH_SUPPORT_AR5416

to enable the extended format descriptors used by 11n parts.
It is now possible to control the chip support included in a
build by specifying exactly which chips are to be supported
in the config file; consult ath_hal(4) for information.

Add mips/conf/DEFAULTS and populate it with:
machine arm
device mem
device uart_ns8250
options GEOM_BSD
options GEOM_MBR

Remove the first three from all kernel configuration files
(sometimes commented-out) and change geom_bsd and geom_mbr
from standard to optional.

Add atheros HAL building so the IDT kernel can build.

mips_subr.c was in the Juniper code drop, but didn't have any
functions used by other code in the tree. As such it was removed from
the merged tree until the functions were needed in the future. The
file was missing from the FreeBSD import, but it was listed in the
files.mips file as being standard. Remove it from there until such
time as we need one.

Minor tweaks to remove references to files that aren't present in the
current FreeBSD/mips source base. Make phases consistent. Remove
comment that's no longer relevant.

Merge in the mips specific configuration files and such from the
merged juniper and mips2 code base. This represents the work of
Juniper Engineers, plus Oleksandr Tymoshenko, Wojciech Koszek, Warner
Losh, Olivier Houchard, Randall Stewert and others that have
contributed to the mips2 and/or mips2-jnpr perforce branches.
