b25a469f94 rcorder(8): add support for /etc/rc.resume, so it calls "rcorder -k resume"
and runs scripts containing "KEYWORD: resume" with single "resume" argument.

Working example is the port sysutils/cpupdate that defines
extra_commands="resume" to reload CPU microcode cleared
by suspend/resume sequence.

This change does nothing for a system having no scripts with KEYWORD: resume.

24b6d87155 Redo r339563: Remove joy(4) driver.
This driver was marked as gone in 12. We're at 13 now. Remove it.
Data from nycbug's dmesg cache shows only one potential user,
suggesting it never was used much. However, even though this device
has been obsolete for 15 years at least, sys/joystick.h is included in
a number of graphics packages still, so that remains. A full exprun
is needed before that can be removed.

7c320a22df Revert r339563.
I held the mistaken belief this was completely unused. While the
driver is unused and likely not relevant for a long time,
sys/joystick.h lives on in maybe half a dozen ports, even though
hardware to use it hasn't been widely used in maybe 15 years.

b61f314290 Make it possible to disable NUMA support with a tunable.
This provides a chicken switch for anyone negatively impacted by
enabling NUMA in the amd64 GENERIC kernel configuration.  With
NUMA disabled at boot-time, information about the NUMA topology
is not exposed to the rest of the kernel, and all of physical
memory is viewed as coming from a single domain.

This method still has some performance overhead relative to disabling
NUMA support at compile time.

284001a222 Put jail(2) under COMPAT_FREEBSD11. It has been the "old" way of creating
jails since FreeBSD 7.

Along with the system call, put the various security.jail.allow_foo and
security.jail.foo_allowed sysctls partly under COMPAT_FREEBSD11 (or
BURN_BRIDGES).  These sysctls had two disparate uses: on the system side,
they were global permissions for jails created via jail(2) which lacked
fine-grained permission controls; inside a jail, they're read-only
descriptions of what the current jail is allowed to do.  The first use
is obsolete along with jail(2), but keep them for the second-read-only use.

(https://github.com/YutaroHayakawa/generic-ebpf).

The BPF target support can be enabled using WITH_LLVM_TARGET_BPF, as it

95a914f631 Address concerns about CPU usage while doing TCP reassembly.
Currently, the per-queue limit is a function of the receive buffer
size and the MSS.  In certain cases (such as connections with large
receive buffers), the per-queue segment limit can be quite large.
Because we process segments as a linked list, large queues may not
perform acceptably.

The better long-term solution is to make the queue more efficient.
But, in the short-term, we can provide a way for a system
administrator to set the maximum queue size.

We set the default queue limit to 100.  This is an effort to balance
performance with a sane resource limit.  Depending on their
environment, goals, etc., an administrator may choose to modify this
limit in either direction.

87842989f8 Add ioctl to conveniently mmap a PCI device BAR into userspace.
Add the ioctl PCIOCBARMMAP on /dev/pci to conveniently create
userspace mapping of a PCI device BAR.  This is enormously superior to
read the BAR value with PCIOCREAD and then try to mmap /dev/mem, and
should allow to automatically activate the mapped BARs when needed in
future.

Current implementation creates new sg pager for each user mmap
request.  If the pointer (and reference) to a managed device pager is
stored in pci_map, we would be able to revoke all mappings on the BAR
deactivation or relocation.  This is related to the unimplemented BAR
activation on mmap, and is postponed for the future.

6040822c4e Make timespecadd(3) and friends public
The timespecadd(3) family of macros were imported from NetBSD back in
r35029. However, they were initially guarded by #ifdef _KERNEL. In the
meantime, we have grown at least 28 syscalls that use timespecs in some
way, leading many programs both inside and outside of the base system to
redefine those macros. It's better just to make the definitions public.

Our kernel currently defines two-argument versions of timespecadd and
timespecsub.  NetBSD, OpenBSD, and FreeDesktop.org's libbsd, however, define
three-argument versions.  Solaris also defines a three-argument version, but
only in its kernel.  This revision changes our definition to match the
common three-argument version.

Bump _FreeBSD_version due to the breaking KPI change.

This change adds a new make.conf variable, MAN_ARCH, which can be a list of

3496c981ac Make it possible to run ntpd as a non-root user, add ntpd uid and gid.
Code analysis and runtime analysis using truss(8) indicate that the only
privileged operations performed by ntpd are adjusting system time, and
(re-)binding to privileged UDP port 123. These changes add a new mac(4)
policy module, mac_ntpd(4), which grants just those privileges to any
process running with uid 123.

This also adds a new user and group, ntpd:ntpd, (uid:gid 123:123), and makes
them the owner of the /var/db/ntp directory, so that it can be used as a
location where the non-privileged daemon can write files such as the
driftfile, and any optional logfile or stats files.

Because there are so many ways to configure ntpd, the question of how to
configure it to run without root privs can be a bit complex, so that will be
addressed in a separate commit. These changes are just what's required to
grant the limited subset of privs to ntpd, and the small change to ntpd to
prevent it from exiting with an error if running as non-root.

1b0909d51a OpenCrypto: Convert sessions to opaque handles instead of integers
Track session objects in the framework, and pass handles between the
framework (OCF), consumers, and drivers.  Avoid redundancy and complexity in
individual drivers by allocating session memory in the framework and
providing it to drivers in ::newsession().

Session handles are no longer integers with information encoded in various
high bits.  Use of the CRYPTO_SESID2FOO() macros should be replaced with the
appropriate crypto_ses2foo() function on the opaque session handle.

Convert OCF drivers (in particular, cryptosoft, as well as myriad others) to
the opaque handle interface.  Discard existing session tracking as much as
possible (quick pass).  There may be additional code ripe for deletion.

Convert OCF consumers (ipsec, geom_eli, krb5, cryptodev) to handle-style
interface.  The conversion is largely mechnical.

The change is documented in crypto.9.

2bf9501287 Create a new macro for static DPCPU data.
On arm64 (and possible other architectures) we are unable to use static
DPCPU data in kernel modules. This is because the compiler will generate
PC-relative accesses, however the runtime-linker expects to be able to
relocate these.

In preparation to fix this create two macros depending on if the data is
global or static.

cc535c95ca Revert r335833.
Several third-parties use at least some of these ioctls.  While it would be
better for regression testing if they were used in base (or at least in the
test suite), it's currently not worth the trouble to push through removal.

since May 2009 when old USB stack was replaced with USB2 implentation.
Current API has the same set of ioctl calls but uses usb_gen_descriptor

0d3d234cd1 carp: Set DSCP value CS7
Update carp to set DSCP value CS7(Network Traffic) in the flowlabel field of
packets by default. Currently carp only sets TOS_LOWDELAY in IPv4 which was
deprecated in 1998. This also implements sysctl that can revert carp back to
it's old behavior if desired.

This will allow implementation of QOS on modern network devices to make sure
carp packets aren't dropped during interface contention.

c1887e9f09 pf: remove unused ioctls.
Several ioctls are unused in pf, in the sense that no base utility
references them.  Additionally, a cursory review of pf-based ports
indicates they're not used elsewhere either.  Some of them have been
unused since the original import.  As far as I can tell, they're also
unused in OpenBSD.  Finally, removing this code removes the need for
future pf work to take them into account.

217df2da08 geli attach multiple providers
Allow attaching of multiple geli providers at once if they use same
passphrase and keyfiles.

This is helpful when the providers being attached are not used for boot,
and therefore the existing code to first try the cached password when
tasting the providers during boot does not apply.

Multiple providers with the same passphrase and keyfiles can be attached
at the same time during system start-up by adding the following to
rc.conf:
  geli_groups="storage backup"
  geli_storage_flags="-k /etc/geli/storage.keys"
  geli_storage_devices="ada0 ada1"
  geli_backup_flags="-j /etc/geli/backup.passfile -k /etc/geli/backup.keys"
  geli_backup_devices="ada2 ada3"

150182e309 pf: Support "return" statements in passing rules when they fail.
Normally pf rules are expected to do one of two things: pass the traffic or
block it. Blocking can be silent - "drop", or loud - "return", "return-rst",
"return-icmp". Yet there is a 3rd category of traffic passing through pf:
Packets matching a "pass" rule but when applying the rule fails. This happens
when redirection table is empty or when src node or state creation fails. Such
rules always fail silently without notifying the sender.

Allow users to configure this behaviour too, so that pf returns an error packet
in these cases.

cbafd2630b Add support for selectively enabling LLVM targets
This makes it possible, through src.conf(5) settings, to select which
LLVM targets you want to build during buildworld.  The current list is:

* (WITH|WITHOUT)_LLVM_TARGET_AARCH64
* (WITH|WITHOUT)_LLVM_TARGET_ARM
* (WITH|WITHOUT)_LLVM_TARGET_MIPS
* (WITH|WITHOUT)_LLVM_TARGET_POWERPC
* (WITH|WITHOUT)_LLVM_TARGET_SPARC
* (WITH|WITHOUT)_LLVM_TARGET_X86

To not influence anything right now, all of these are on by default, in
situations where clang is enabled.

Selectively turning a few targets off manually should work.  Turning on
only one target should work too, even if that target does not correspond
to the build architecture.  (In that case, LLVM_NATIVE_ARCH will not be
defined, and you can only use the resulting clang executable for
cross-compiling.)

I performed a few measurements on one of the FreeBSD.org reference
machines, building clang from scratch, with all targets enabled, and
with only the x86 target enabled.  The latter was ~12% faster in real
time (on a 32-core box), and ~14% faster in user time.  For a full
buildworld the difference will probably be less pronounced, though.
