09ed804717 gai_strerror() - Update string error messages according to RFC 3493.
Error messages in gai_strerror(3) vary largely among OSs.

For new software we largely replaced the obsoleted EAI_NONAME and
with EAI_NODATA but we never updated the corresponding message to better
match the intended use. We also have references to ai_flags and ai_family
which are not very descriptive for non-developer end users.

Bring new new error messages based on informational RFC 3493, which has
obsoleted RFC 2553, and make them consistent among the header adn
manpage.

8bff61a6ba Reduce NL_ARGMAX to 4096 to match Linux.
NL_ARGMAX is the maximum number of positional arguments supported by
printf(3). Prior to r308145 it was declared as 99 and not enforced.
r308145 added enforcement and increased the value to 64k.

Unfortunately, development versions of PostgreSQL used the system
definition to allocate and zero an NL_ARGMAX * 4 sized array on the
stack of its snprintf implementation with measurable performance
impacts. This has been fixed in new PostgreSQL versions, but it is
possible that other programs suffer from this problem.

A value of 4096 puts us on par with Linux and is certainly large enough
for any reasonable program.

ce33c57d6c Use INCS for non-sys/ libnvpair and libzfs_core includes
While nothing was wrong with libnvpair.h, libzfs_core.h was only guarded by
MK_CDDL rather than MK_CDDL && MK_ZFS. Rather than ugl'if'ying
include/Makefile to impose the extra restriction, just move the non-sys/
includes into INCS with the respect lib builds.

This has the added bonus of allowing third party packagers to try and split
these libs out of the FreeBSD-runtime package, if they are so inclined.

The sys/ include was left alone- generally userland libraries shouldn't

aad5531e71 This exposes ZFS user and group quotas via the normal
quatactl(2) mechanism.  (Read-only at this point, however.)
In particular, this is to allow rpc.rquotad query quotas
for NFS mounts, allowing users to see their quotas on the
hosts using the datasets.

The changes specifically:

* Add new RPC entry points for querying quotas.
* Changes the library routines to allow non-UFS quotas.
* Changes rquotad to check for quotas on mounted filesystems,
rather than being limited to entries in /etc/fstab
* Lastly, adds a VFS entry-point for ZFS to query quotas.

Note that this makes one unavoidable behavioural change: if quotas
are enabled, then they can be queried, as opposed to the current
method of checking for quotas being specified in fstab.  (With
ZFS, if there are user or group quotas, they're used, always.)

e505460228 Import the netdump client code.
This is a component of a system which lets the kernel dump core to
a remote host after a panic, rather than to a local storage device.
The server component is available in the ports tree. netdump is
particularly useful on diskless systems.

The netdump(4) man page contains some details describing the protocol.
Support for configuring netdump will be added to dumpon(8) in a future
commit. To use netdump, the kernel must have been compiled with the
NETDUMP option.

The initial revision of netdump was written by Darrell Anderson and
was integrated into Sandvine's OS, from which this version was derived.

2529f56ed3 Add the "TCP Blackbox Recorder" which we discussed at the developer
summits at BSDCan and BSDCam in 2017.

The TCP Blackbox Recorder allows you to capture events on a TCP connection
in a ring buffer. It stores metadata with the event. It optionally stores
the TCP header associated with an event (if the event is associated with a
packet) and also optionally stores information on the sockets.

It supports setting a log ID on a TCP connection and using this to correlate
multiple connections that share a common log ID.

You can log connections in different modes. If you are doing a coordinated
test with a particular connection, you may tell the system to put it in
mode 4 (continuous dump). Or, if you just want to monitor for errors, you
can put it in mode 1 (ring buffer) and dump all the ring buffers associated
with the connection ID when we receive an error signal for that connection
ID. You can set a default mode that will be applied to a particular ratio
of incoming connections. You can also manually set a mode using a socket
option.

This commit includes only basic probes. rrs@ has added quite an abundance
of probes in his TCP development work. He plans to commit those soon.

There are user-space programs which we plan to commit as ports. These read
the data from the log device and output pcapng files, and then let you
analyze the data (and metadata) in the pcapng files.

e9ac27430c Implement getrandom(2) and getentropy(3)
The general idea here is to provide userspace programs with well-defined
sources of entropy, in a fashion that doesn't require opening a new file
descriptor (ulimits) or accessing paths (/dev/urandom may be restricted
by chroot or capsicum).

getrandom(2) is the more general API, and comes from the Linux world.
Since our urandom and random devices are identical, the GRND_RANDOM flag
is ignored.

getentropy(3) is added as a compatibility shim for the OpenBSD API.

truss(1) support is included.

Tests for both system calls are provided.  Coverage is believed to be at
least as comprehensive as LTP getrandom(2) test coverage.  Additionally,
instructions for running the LTP tests directly against FreeBSD are provided
in the "Test Plan" section of the Differential revision linked below.  (They
pass, of course.)

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.

nothing - it was checking for ENXIO, which, with devfs, is no longer
returned - and was badly placed anyway, and replaces it with similar
one that works, and is done just before starting getty, instead of being
done when rereading ttys(5).

From the practical point of view, this makes init(8) handle disappearing

and resulting error messages.

93ca7f45e7 Sync (make same) the offsetof macro definition in include/ with the
definition of the same in sys/sys/. The problem was discovered while
working on implementing a new C11 gets_s() for libc. (The new gets_s()
requires rsize_t found in include/stddef.h.) The solution to sync the two
definitions was suggested by ed@ while discussing D12667.

a94a63f0a6 An MMC/SD/SDIO stack using CAM
Implement the MMC/SD/SDIO protocol within a CAM framework. CAM's
flexible queueing will make it easier to write non-storage drivers
than the legacy stack. SDIO drivers from both the kernel and as
userland daemons are possible, though much of that functionality will
come later.

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
have been overlooked.

f49db4cf69 Use __ISO_C_VISIBLE, as opposed to testing __STDC_VERSION__.
FreeBSD's C library uses __STDC_VERSION__ to determine whether the
compiler provides language features specific to a certain version of the
C standard. __ISO_C_VISIBLE is used to specify which library features
need to be exposed.

max_align_t currently uses __STDC_VERSION__, even though it should be
using __ISO_C_VISIBLE to remain consistent with the rest of the headers
in include/.

c99b67a794 Utilize SYSROOT from r320119 in places where DESTDIR may be wanting WORLDTMP.
Since buildenv exports SYSROOT all of these uses will now look in
WORLDTMP by default.

        A LIBSTAND hack is no longer required for buildenv.
