keep state is used, which is redundant because keep state currently
assumes keep frags. This commit fixes this.
To the user this change means that to maintain the current behaviour
one must add keep frags to any ipfilter keep state rule (as documented
in the man pages).
This patch also allows the flexability to specify and use keep frags
separate from keep state, as documented in an example in ipf.conf.5,
instead of the currently broken behaviour.

This portion of the patch was inspired by NetBSD ip_frag.c r1.4 (which
effectively removed the section of code that performed the reordering).
The patch to sys/contrib/ipfilter/netinet/ip_compat.h adds the

Languages like C++17 and Go provide direct support for slice types:
pointer/length pairs. The CloudABI generator now has more complete for
this, meaning that for the C binding, pointer/length pairs now use an
automatic naming scheme of ${name} and ${name}_len.
Apart from this change and some reformatting, the ABI definitions are
identical. Binary compatibility is preserved entirely.
Include netinet/in.h before ip_compat.t which will then check if
IPPROTO_IPIP is defined or not. Doing it the other way round,
ip_compat.h would not find it defined and netinet/in.h then

- Use conditional instruction to simplify the ARMv6 vDSO. This means
that we no longer perform any branching. In the failure case, we
simply slide over the assignments of the return values.
The vDSO could be improved even further by using stmia to do
assignments in parallel. Unfortunately, the script used to generate
these is not smart enough for that (yet).
Spotted by: andrew@.
- Make the style of the i686 vDSO more similar to the others by using
decimal literals.
Bugs in the Python code used to generate this vDSO caused us to
miscompute the register numbers/stack offsets at which addresses of the

Together with some other patches, this vDSO allows us to make all of the
cloudlibc unit tests pass.

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.

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.

The native CloudABI data types header file used to be pulled in by the
vDSOs when they were still written in C. Since they are now all
rewritten in assembly, this can go away.
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.

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.

Now that we've switched over to using the vDSO on CloudABI, it becomes a
lot easier for us to phase out old features. System call numbering is no
longer something that's part of the ABI. It's fully based on names. As
long as the numbering used by the kernel and the vDSO is consistent
(which it always is), it's all right.
Let's put this to the test by removing a system call (thread_tcb_set())
that's already unused for quite some time now, but was only left intact
to serve as a placeholder. Sync in the new system call table that uses
alphabetic sorting of system calls.

CloudABI executables that are emulated on Mac OS X do not invoke system
calls through "syscall". Instead, they make use of a vDSO that is
provided by the emulator that provides symbols for all of the system
call routines. The emulator can implement these any way it likes.
At some point in time we want to do this for native execution as well,
so that CloudABI executables are entirely oblivious of how system calls
need to be performed. They will simply call into functions and let that
deal with all of the details.
These source files can be used to generate a simple vDSO that does
nothing more than invoke "syscall". All we need to do now is map it into

* add support to read the timer and capability
* add support to enable/disable the location timer.
On AR9380 at least, enabling the location timer is required to make
the timer tick, otherwise location packets return a timestamp of 0.
However, it then makes /all/ RX packets use the RX location timestamp
instead of the TSF timestamp.
So, unless I find another magical way to do location timestamping,
we will have to dynamically switch things on/off and ensure the
TX/RX path handles the "different" timestamps correctly.
Tested:
* AR9380, STA mode
* LOC_INFO is mostly just "did this packet come with a locationing
timestamp instead of TSF";
* Decode not-sounding, uploaded-data, data-valid, data type and
number of extension spatial streams.
* If fast_ts is set then the TX timestamp is the fast timestamp, not
normal TSF.
* If the TX descriptor has the position bit set then request locationing
and clear sounding-disable. This way we (a) get the response with
the TX timestamp from the location side of things, and (b) we get
a CSI dump of the response ACK, which we will eventually use in the
locationing path.
* the code already stored the length of the RX desc, which I never used.
So, use that and retire the new flag I introduced a while ago.
* Introduce a TX timestamp length field and capability.

Split initializzation an teardown into module (global state) and VNET
(per virtual network stack) parts. Virtualise global state, which is
not "const".
Cleanup eventhandlers, so that we can make use of the passed in argument
to get the vnet state from the ifp; disable the "cloner" event as it is
too early, has no state, and can fire before initialisation (see comment
in the source).
Handle the dynamic sysctls specially. The problem is that "ipmain"
is the virtualized struct, but the fields used for the sysctls are
hanging off memory allocated and attached to the virtualized "ipmain"
thus standard VNET macros and sysctl handling do not work.
We still say it is VNET sysctls to get the proper protection checks
in the VIMAGE case; to solve the problem of accessing the right bit
of memory hanging of each per-VNET ipmain, we use a dedicated handler
function wrapping around sysctl_ipf_int() undoing the base calculation
from kern_sysctl.c and then adding the passed-in offset into the right
struct depending on handler. A bit of a mess exposing VNET-internals
this way but the only way to keep the code without having to massively
restructure ipf internals.

than removing the network interfaces first. This change is rather larger
and convoluted as the ordering requirements cannot be separated.
Move the pfil(9) framework to SI_SUB_PROTO_PFIL, move Firewalls and

Move initialization of "physical" interfaces to SI_SUB_DRIVERS,
move virtual (cloned) interfaces to SI_SUB_PSEUDO.
Move Multicast to SI_SUB_PROTO_MC.
Re-work parts of multicast initialisation and teardown, not taking the
huge amount of memory into account if used as a module yet.
For interface teardown we try to do as many of them as we can on
SI_SUB_INIT_IF, but for some this makes no sense, e.g., when tunnelling
over a higher layer protocol such as IP. In that case the interface
has to go along (or before) the higher layer protocol is shutdown.
Kernel hhooks need to go last on teardown as they may be used at various
higher layers and we cannot remove them before we cleaned up the higher
layers.
For interface teardown there are multiple paths:
(a) a cloned interface is destroyed (inside a VIMAGE or in the base system),
(b) any interface is moved from a virtual network stack to a different
network stack ("vmove"), or (c) a virtual network stack is being shut down.
All code paths go through if_detach_internal() where we, depending on the
vmove flag or the vnet state, make a decision on how much to shut down;
in case we are destroying a VNET the individual protocol layers will
cleanup their own parts thus we cannot do so again for each interface as
we end up with, e.g., double-frees, destroying locks twice or acquiring
already destroyed locks.
When calling into protocol cleanups we equally have to tell them
whether they need to detach upper layer protocols ("ulp") or not
(e.g., in6_ifdetach()).
Provide or enahnce helper functions to do proper cleanup at a protocol
rather than at an interface level.

We're currently seeing how hard it would be to run CloudABI binaries on
operating systems cannot be modified easily (Windows, Mac OS X). The
idea is that we want to just run them without any sandboxing. Now
that CloudABI executables are PIE, this is already a bit easier, but TLS
is still problematic:
- CloudABI executables want to write to the %fs, which typically
requires extra system calls by the emulator every time it needs to
switch between CloudABI's and its own TLS.
- If CloudABI executables overwrite the %fs base unconditionally, it
also becomes harder for the emulator to store a backup of the old
value of %fs. To solve this, let's no longer overwrite %fs, but just
%fs:0.
As CloudABI's C library does not use a TCB, this space can now be used
by an emulator to keep track of its internal state. The executable can
now safely overwrite %fs:0, as long as it makes sure that the TCB is
copied over to the new TLS area.
Ensure that there is an initial TLS area set up when the process starts,
only containing a bogus TCB. We don't really care about its contents on
FreeBSD.

The type definitions and constants that were used by COMPAT_CLOUDABI64

library, cloudlibc. What is annoying is that we can't make use of
cloudlibc's system call list, as the format is completely different and
doesn't provide enough information. It had to be synced in manually.
We recently decided to solve this (and some other problems) by moving
the ABI definitions into a separate file:
https://github.com/NuxiNL/cloudabi/blob/master/cloudabi.txt
This file is processed by a pile of Python scripts to generate the
header files like before, documentation (markdown), but in our case more
importantly: a FreeBSD system call table.
This change discards the old files in sys/contrib/cloudabi and replaces
them by the latest copies, which requires some minor changes here and
there. Because cloudabi.txt also enforces consistent names of the system
call arguments, we have to patch up a small number of system call
implementations to use the new argument names.
The new header files can also be included directly in FreeBSD kernel
space without needing any includes/defines, so we can now remove
cloudabi_syscalldefs.h and cloudabi64_syscalldefs.h. Patch up the
sources to include the definitions directly from sys/contrib/cloudabi
instead.
Freescale's QorIQ line includes a new ethernet controller, based on their
Datapath Acceleration Architecture (DPAA). This uses a combination of a Frame
manager, Buffer manager, and Queue manager to improve performance across all
interfaces by being able to pass data directly between hardware acceleration
interfaces.
As part of this import, Freescale's Netcomm Software (ncsw) driver is imported.
This was an attempt by Freescale to create an OS-agnostic sub-driver for
managing the hardware, using shims to interface to the OS-specific APIs. This
work was abandoned, and Freescale's primary work is in the Linux driver (dual
BSD/GPL license). Hence, this was imported directly to sys/contrib, rather than
going through the vendor area. Going forward, FreeBSD-specific changes may be
made to the ncsw code, diverging from the upstream in potentially incompatible
ways. An alternative could be to import the Linux driver itself, using the
linuxKPI layer, as that would maintain parity with the vendor-maintained driver.
However, the Linux driver has not been evaluated for reliability yet, and may
have issues with the import, whereas the ncsw-based driver in this commit was
completed by Semihalf 4 years ago, and is very stable.
