0835cc783b Add SPDX license tag to the ENA driver files
Refering to guide: https://wiki.freebsd.org/SPDX the SPDX tag should not
replace the standard license text, however it should be added over the
standard license text to make the automation easier.

Because of that, the old license was kept, but the SPDX tag was added
on top of every ENA driver file.

ede4af47ae unix(4): Enhance LOCAL_CREDS_PERSISTENT ABI
As this ABI is still fresh (r367287), let's correct some mistakes now:

- Version the structure to allow for future changes
- Include sender's pid in control message structure
- Use a distinct control message type from the cmsgcred / sockcred mess

9a4d64029e Fix make makeman after r367577
WITH_INIT_ALL_ZERO and WITH_INIT_ALL_PATTERN are mutually exclusive.
The .error when they were both set broke makeman so demote it to a
warning (and presumably the compiler will fail on an error later on).

We could improve this to make one take precedence but this is sufficient
for now.

e268fd0a02 Support initializing stack variables on function entry
There are two options:
 - WITH_INIT_ALL_ZERO: Zero all variables on the stack.
 - WITH_INIT_ALL_PATTERN: Initialize variables with well-defined patterns.

The exact pattern are a compiler implementation detail and vary by type.
They are somewhat documented in the LLVM commit message:
https://reviews.llvm.org/rL349442
I've used WITH_INIT_ALL_* to match Microsoft's InitAll feature rather
than naming them after the LLVM specific compiler flags.

In a range of consumer products, options like these are used in
both debug and production builds with debugs builds using patterns
(intended to provoke crashes on use of uninitialized values) and
production using zeros (deemed more likely to lead to harmless
misbehavior or NULL-pointer dereferences).

8ec6c4a38b - add more linux socket options (sorted by value)
- map those IPv4 / IPv6 socket options which exist in FreeBSD
   + most of them visually verified to have the same type/layout of arguments
   + not tested with linux programs to behave as intended
 - be more human readable for known options which are not handled
 - be more verbose for unhandled socket message flags we know about
 - print the jail ID in linux_msg if run in a jail
 - add possibility to print debug message about known missing parts only once
 - add multiple levels of sysctl linux.debug:
   1: print debug messages, tell about unimplemented stuff (only once)
   2: like 1, but also print messages about implemented but not tested
      stuff (only once)
   3+: like 2, but no rate limiting of messages
 - increase default linux debug level from 1 to 3

We are a lot more verbose in as we need to be (e.g. some of the IP socket
options which are the same, and share the same memory layout, and are
believed to work). The reason is that we have no good testsuite to test those
linux-bits. The LTP or other test suites like the python one, are not fully
up to the task we need. As such the excessive messages about emulated but not
tested socket options.

IMO any MFC (possible, but most probably not by me) should set the default
debug level to 1.

cc7edd258c Add collation version support to querylocale(3).
Provide a way to ask for an opaque version string for a locale_t, so
that potential changes in sort order can be detected.  Similar to
ICU's ucol_getVersion() and Windows' GetNLSVersionEx(), this API is
intended to allow databases to detect when text order-based indexes
might need to be rebuilt.

The CLDR version is extracted from CLDR source data by the Makefile
under tools/tools/locale, written into the machine-generated Makefile
under shared/colldef, passed to localedef -V, and then written into
LC_COLLATE file headers.  The initial version is 34.0.
tools/tools/locale was recently updated to pull down 35.0, but the
output hasn't been committed under share/colldef yet, so that will
provide the first observable change when it happens.  Other versioning
schemes are possible in future, because the format is unspecified.

intercept atomic(9) calls, and makes tricky lockless code easier to read

Since elftoolchain's cxxfilt is rather far behind on features, and we

It supports the same options as elftoolchain cxxfilt, though it doesn't
have support for old ARM (C++ Annotated Reference Manual, not the CPU)
and GNU v2 manglings. But these are irrelevant in 2020.

Note: as we already compile the required libraries as part of libllvm,
this will not add any significant build time either.

77af2b2c85 cxgbe(4): knobs to drop various kinds of undesirable frames on ingress.
These kind of drops come for free in the sense that they do not use the
filter TCAM or any other resource that wouldn't normally be used during
rx.  Frames dropped by the hardware get counted in the MAC's rx stats
but are not delivered to the driver.

hw.cxgbe.attack_filter
Set to 1 to enable the "attack filter".  Default is 0.  The attack
filter will drop an incoming frame if any of these conditions is true:
src ip/ip6 == dst ip/ip6; tcp and src/dst ip is not unicast; src/dst ip
is loopback (127.x.y.z); src ip6 is not unicast; src/dst ip6 is loopback
(::1/128) or unspecified (::/128); tcp and src/dst ip6 is mcast
(ff00::/8).

hw.cxgbe.drop_ip_fragments
Set to 1 to drop all incoming IP fragments.  Default is 0.  Note that
this drops valid frames.

hw.cxgbe.drop_pkts_with_l2_errors
Set to 1 to drop incoming frames with Layer 2 length or checksum errors.
Default is 1.

hw.cxgbe.drop_pkts_with_l3_errors
Set to 1 to drop incoming frames with IP version, length, or checksum
errors.  Default is 0.

hw.cxgbe.drop_pkts_with_l4_errors
Set to 1 to drop incoming frames with Layer 4 length, checksum, or other
errors.  Default is 0.

c1aedfcbd9 add SIOCGIFDATA ioctl
For interfaces that do not support SIOCGIFMEDIA (for which there are
quite a few) the only fallback is to query the interface for
if_data->ifi_link_state.  While it's possible to get at if_data for an
interface via getifaddrs(3) or sysctl, both are heavy weight mechanisms.

SIOCGIFDATA is a simple ioctl to retrieve this fast with very little
resource use in comparison.  This implementation mirrors that of other
similar ioctls in FreeBSD.

Certain things are subject to change while this is experimental. The most

emulation assistance for __float128 being set up in the compiler (as
POWER8 does not have IEEE-compatible 128-bit hardware float, unlike POWER9.)

cba446e2c2 Add getenv(9) boolean parsing functions
This adds the getenv_bool() function, to parse a boolean value from a
kernel environment variable or tunable. This works for traditional
boolean values like "0" and "1", and also "true" and "false"
(case-insensitive). These semantics do not yet apply to sysctls declared
using SYSCTL_BOOL with CTLFLAG_TUN (they still only parse 1 and 0).

Also added are two wrapper functions, getenv_is_true() and
getenv_is_false(). These are slightly simpler for callers wishing to
perform a single check of a configuration variable.

e307eb94ae loader: zfs should support bootonce an nextboot
bootonce feature is temporary, one time boot, activated by
"bectl activate -t BE", "bectl activate -T BE" will reset the bootonce flag.

By default, the bootonce setting is reset on attempt to boot and the next
boot will use previously active BE.

By setting zfs_bootonce_activate="YES" in rc.conf, the bootonce BE will
be set permanently active.

bootonce dataset name is recorded in boot pool labels, bootenv area.

in case of nextboot, the nextboot_enable boolean variable is recorded in
freebsd:nvstore nvlist, also stored in boot pool label bootenv area.
On boot, the loader will process /boot/nextboot.conf if nextboot_enable
is "YES", and will set nextboot_enable to "NO", preventing /boot/nextboot.conf
processing on next boot.

bootonce and nextboot features are usable in both UEFI and BIOS boot.

To use bootonce/nextboot features, the boot loader needs to be updated on disk;
if loader.efi is stored on ESP, then ESP needs to be updated and
for BIOS boot, stage2 (zfsboot or gptzfsboot) needs to be updated
(gpart or other tools).

At this time, only lua loader is updated.

95a85c125d Add NetBSD compatible bus_space_peek_N() and bus_space_poke_N() functions.
One problem with the bus_space_read_N() and bus_space_write_N() family of
functions is that they provide no protection against exceptions which can
occur when no physical hardware or device responds to the read or write
cycles. In such a situation, the system typically would panic due to a
kernel-mode bus error. The bus_space_peek_N() and bus_space_poke_N() family
of functions provide a mechanism to handle these exceptions gracefully
without the risk of crashing the system.

Typical example is access to PCI(e) configuration space in bus enumeration
function on badly implemented PCI(e) root complexes (RK3399 or Neoverse
N1 N1SDP and/or access to PCI(e) register when device is in deep sleep state.

This commit adds a real implementation for arm64 only. The remaining
architectures have bus_space_peek()/bus_space_poke() emulated by using
bus_space_read()/bus_space_write() (without exception handling).

fe815331bb build: provide a default WARNS for all in-tree builds
The current default is provided in various Makefile.inc in some top-level
directories and covers a good portion of the tree, but doesn't cover parts
of the build a little deeper (e.g. libcasper).

Provide a default in src.sys.mk and set WARNS to it in bsd.sys.mk if that
variable is defined. This lets us relatively cleanly provide a default WARNS
no matter where you're building in the src tree without breaking things
outside of the tree.

Crunchgen has been updated as a bootstrap tool to work on this change
because it needs r365605 at a minimum to succeed. The cleanup necessary to
successfully walk over this change on WITHOUT_CLEAN builds has been added.

There is a supplemental project to this to list all of the warnings that are
encountered when the environment has WARNS=6 NO_WERROR=yes:
https://warns.kevans.dev -- this project will hopefully eventually go away
in favor of CI doing a much better job than it.
