d3a5bf95f2 Make the warning for deprecated NO_ variables an error.
Support for NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, NO_MAN, NO_PROFILE,
and NO_WARNS as deprecated in 2014 with a warning added for each one
found. Turn these into error in preperation for removal of compatability
support before FreeBSD 13.

This was previously committed in r354909 and reverted in r355011 due to
unforseen impacts on ports.  I've since corrected all amd64 and i386
ports reported in prior runs as well as instance of these variables I
found via grep.

eb4977bd0f Remove arm/arm as a valid target.
TARGET=arm now defaults to TARGET_ARCH=armv7
TARGET_ARCH=arm is no longer valid.

Bump __FreeBSD_version to 1300073

Tested with make universe. Any stale LINT-V5 config files remaining in the tree
will fail the universe build. However, LINT-V5 was removed in r355119.

This retirement has been planned since last summer. The armv5 port is fragile:
it works OK for some peeople, and fails badly for others. There's a number of
subtle bugs in busdma, pmap and other MD parts of thee system that present
themselves under load or in unusual circumstances (like fsck after a
crash). stable/8, branched 10 years ago, was the last reliable release.  Since
the support burden is larger then the benefit, the consensus view is armv5
should be removed from the tree.

Discussed with: arm@ mailing list and arm developer community.

3ee1d5bb9d random(4): Simplify RANDOM_LOADABLE
Simplify RANDOM_LOADABLE by removing the ability to unload a LOADABLE
random(4) implementation.  This allows one-time random module selection
at boot, by loader(8).  Swapping modules on the fly doesn't seem
especially useful.

This removes the need to hold a lock over the sleepable module calls
read_random and read_random_uio.

init/deinit have been pulled out of random_algorithm entirely.  Algorithms
can run their own sysinits to initialize; deinit is removed entirely, as
algorithms can not be unloaded.  Algorithms should initialize at
SI_SUB_RANDOM:SI_ORDER_SECOND.  In LOADABLE systems, algorithms install
a pointer to their local random_algorithm context in p_random_alg_context at
that time.

Go ahead and const'ify random_algorithm objects; there is no need to mutate
them at runtime.

LOADABLE kernel NULL checks are removed from random_harvestq by ordering
random_harvestq initialization at SI_SUB_RANDOM:SI_ORDER_THIRD, after
algorithm init.  Prior to random_harvestq init, hc_harvest_mask is zero and
no events are forwarded to algorithms; after random_harvestq init, the
relevant pointers will already have been installed.

Remove the bulk of random_infra shim wrappers and instead expose the bare
function pointers in sys/random.h.  In LOADABLE systems, read_random(9) et
al are just thin shim macros around invoking the associated function
pointer.  We do not provide a registration system but instead expect
LOADABLE modules to register themselves at SI_SUB_RANDOM:SI_ORDER_SECOND.
An example is provided in randomdev.c, as used in the random_fortuna.ko
module.

3d5013337a tuntap(4): restrict scope of net.link.tap.user_open slightly
net.link.tap.user_open has historically allowed non-root users to do devfs
cloning and open /dev/tap* nodes based on permissions. Loosen this up to
make it only allow users to do devfs cloning -- we no longer check it in
tunopen.

This allows tap devices to be created that can actually be opened by a user,
rather than swiftly restricting them to root because the magic sysctl has
not been set.

The sysctl has not yet been completely deprecated, because more thought is
needed for how to handle the devfs cloning case. There is not an easy
suitable replacement for the sysctl there, and more care needs to be placed
in determining whether that's OK or not.

4c62bffef5 Fix dpcpu and vnet panics with complex types at the end of the section.
Apply a linker script when linking i386 kernel modules to apply padding
to a set_pcpu or set_vnet section.  The padding value is kind-of random
and is used to catch modules not compiled with the linker-script, so
possibly still having problems leading to kernel panics.

This is needed as the code generated on certain architectures for
non-simple-types, e.g., an array can generate an absolute relocation
on the edge (just outside) the section and thus will not be properly
relocated. Adding the padding to the end of the section will ensure
that even absolute relocations of complex types will be inside the
section, if they are the last object in there and hence relocation will
work properly and avoid panics such as observed with carp.ko or ipsec.ko.

There is a rather lengthy discussion of various options to apply in
the mentioned PRs and their depends/blocks, and the review.
There seems no best solution working across multiple toolchains and
multiple version of them, so I took the liberty of taking one,
as currently our users (and our CI system) are hitting this on
just i386 and we need some solution.  I wish we would have a proper
fix rather than another "hack".

Also backout r340009 which manually, temporarily fixed CARP before 12.0-R
"by chance" after a lead-up of various other link-elf.c and related fixes.

542970fa2d Remove IPSEC from GENERIC due to performance issues
Having IPSEC compiled into the kernel imposes a non-trivial
performance penalty on multi-threaded workloads due to IPSEC
refcounting. In my benchmarks of multi-threaded UDP
transmit (connected sockets), I've seen a roughly 20% performance
penalty when the IPSEC option is included in the kernel (16.8Mpps
vs 13.8Mpps with 32 senders on a 14 core / 28 HTT Xeon
2697v3)). This is largely due to key_addref() incrementing and
decrementing an atomic reference count on the default
policy. This cause all CPUs to stall on the same cacheline, as it
bounces between different CPUs.

Given that relatively few users use ipsec, and that it can be
loaded as a module, it seems reasonable to ask those users to
load the ipsec module so as to avoid imposing this penalty on the
GENERIC kernel. Its my hope that this will make FreeBSD look
better in "out of the box" benchmark comparisons with other
operating systems.

Many thanks to ae for fixing auto-loading of ipsec.ko when
ifconfig tries to configure ipsec, and to cy for volunteering
to ensure the the racoon ports will load the ipsec.ko module

251a32b5b2 tun/tap: merge and rename to tuntap
tun(4) and tap(4) share the same general management interface and have a lot
in common. Bugs exist in tap(4) that have been fixed in tun(4), and
vice-versa. Let's reduce the maintenance requirements by merging them
together and using flags to differentiate between the three interface types
(tun, tap, vmnet).

This fixes a couple of tap(4)/vmnet(4) issues right out of the gate:
- tap devices may no longer be destroyed while they're open [0]
- VIMAGE issues already addressed in tun by kp

[0] emaste had removed an easy-panic-button in r240938 due to devdrn
blocking. A naive glance over this leads me to believe that this isn't quite
complete -- destroy_devl will only block while executing d_* functions, but
doesn't block the device from being destroyed while a process has it open.
The latter is the intent of the condvar in tun, so this is "fixed" (for
certain definitions of the word -- it wasn't really broken in tap, it just
wasn't quite ideal).

ifconfig(8) also grew the ability to map an interface name to a kld, so
that `ifconfig {tun,tap}0` can continue to autoload the correct module, and
`ifconfig vmnet0 create` will now autoload the correct module. This is a
low overhead addition.

(MFC commentary)

This may get MFC'd if many bugs in tun(4)/tap(4) are discovered after this,
and how critical they are. Changes after this are likely easily MFC'd
without taking this merge, but the merge will be easier.

I have no plans to do this MFC as of now.

3782136ff1 random(4): Restore availability tradeoff prior to r346250
As discussed in that commit message, it is a dangerous default.  But the
safe default causes enough pain on a variety of platforms that for now,
restore the prior default.

Some of this is self-induced pain we should/could do better about; for
example, programmatic CI systems and VM managers should introduce entropy
from the host for individual VM instances.  This is considered a future work
item.

On modern x86 and Power9 systems, this may be wholly unnecessary after
D19928 lands (even in the non-ideal case where early /boot/entropy is
unavailable), because they have fast hardware random sources available early
in boot.  But D19928 is not yet landed and we have a host of architectures
which do not provide fast random sources.

This change adds several tunables and diagnostic sysctls, documented
thoroughly in UPDATING and sys/dev/random/random_infra.c.

ba57dad4b0 stack_protector: Add tunable to bypass random cookies
This is a stopgap measure to unbreak installer/VM/embedded boot issues
introduced (or at least exposed by) in r346250.

Add the new tunable, "security.stack_protect.permit_nonrandom_cookies," in
order to continue boot with insecure non-random stack cookies if the random
device is unavailable.

For now, enable it by default.  This is NOT safe.  It will be disabled by
default in a future revision.

There is follow-on work planned to use fast random sources (e.g., RDRAND on
x86 and DARN on Power) to seed when the early entropy file cannot be
provided, for whatever reason.  Please see D19928.

Some better hacks may be used to make the non-random __stack_chk_guard
slightly less predictable (from delphij@ and mjg@); those suggestions are
left for a future revision.  I think it may also be plausible to move stack
guard initialization far later in the boot process; potentially it could be
moved all the way to just before userspace is started.

f3d2512db6 random(4): Add is_random_seeded(9) KPI
The imagined use is for early boot consumers of random to be able to make
decisions based on whether random is available yet or not.  One such
consumer seems to be __stack_chk_init(), which runs immediately after random
is initialized.  A follow-up patch will attempt to address that.

359d22d4e9 Augment ino64 entry
When updating across this change (the introduction of ino64), the
"fast and loose" practice of rebooting to multiuser and then doing an
installworld fails with missing symbols. Recommend strongly that users
do this in single user mode. The multiuser case only ever works by
accident because its requirements are stronger than is supported
accross this change. It usually works because critical symbols don't
change their version number in libc, which wasn't the case here.

explain when compat options are needed (for running existing host
binaries) in a more general way while using a more modern example
(COMPAT_FREEBSD11 for 11.x binaries).  While here, explicitly mention
that a GENERIC kernel should always work.

remove them for all but arm once the transition to drm-*kmod is

532dc17243 lualoader: Create a module blacklist, add DRM modules to it
This is a step in the process of easing migration into the new world order
of DRM drivers. Strongly encourage users towards loading DRM modules via
rc.conf(5) instead of loader.conf(5) by failing the load from loader(8).
Users so inclined may wipe out the blacklist via module_blacklist="" in
loader.conf(5), and it is expected that these modules will eventually be
removed from the blacklist. They may still be loaded as dependencies of
other modules or explicitly via the loader prompt, but this should not be a
major problem.

After long consultations with re@, core members and mmacy, revert

deprecated and prent a message about where to find the up-to-date
driver.  Followup commits will be made to make this clear in the
installer. Followup commits to reduce POLA in ways we're still
exploring.

It's anticipated that after the freeze, this will be removed in
13-current (with the residual of the drm2 code copied to
sys/arm/dev/drm2 for the TEGRA port's use w/o the intel or
radeon drivers).

Due to the impending freeze, there was no formal core vote for
this. I've been talking to different core members all day, as well as
Matt Macey and Glen Barber. Nobody is completely happy, all are
grudgingly going along with this. Work is in progress to mitigate
the negative effects as much as possible.
