Fix sysctl(3):vm.minaddress in compat_netbsd32(8)

Cast minaddress from LP64-specific long (64-bit) to 32-bit long (int).

This value is usually 0 or 0+PAGE_SIZE. There is need to change type in
order to keep original code functional, without prompting the value with
'long long' or a similar approach.

There are more CTLTYPE_LONG with a need for fixes in the compat code:

uipc_usrreq.c
1975 CTLTYPE_LONG, "sendspace",
1981 CTLTYPE_LONG, "recvspace",
1987 CTLTYPE_LONG, "sendspace",
1993 CTLTYPE_LONG, "recvspace",

Revert previous: Don't generate XMSS host keys for sshd by default.

XMSS is a stateful post-quantum signature scheme.

- Post-quantum security for _online_ authentication is not important
  until quantum computers become practical; there's no danger of
  retroactive forgery in sessions that have already completed.

- As a stateful signature schemes, XMSS is qualitatively different
  from all the other ones sshd supports, requiring additional
  administrative care: roll back the state (e.g., from a disk backup
  or VM snapshot), and you've shot yourself in the foot.

If users want XMSS keys, they can make them explicitly, but there's
no need for this to be enabled by default.

Handle vm.maxaddress in compat_netbsd32(8)

Return VM_MAXUSER_ADDRESS32 instead of the 64-bit specific address.

Use CTLTYPE_INT instead of CTLTYPE_LONG in order to retain the same integer
type between 64-bit native kernel and 32-bit emulated program.

There probably should be CTLTYPE_LONG32 available for this purpose.

On NetBSD/i386:
vm.maxaddress=bfeff000

On NetBSD/amd64:
vm.maxaddress=7fbfdfeff000

On NetBSD/amd64 running i386 program:
vm.maxaddress=fffff000

A 32-bit program on the 64-bit kernel can use larger user space, this
difference is on purpose and expected.

Revert my rev1.190, remove the M_READONLY check. The initial code was
correct: what is read-only is the mbuf storage, not the mbuf itself. The
storage contains the packet payload, and never has anything related to
mbufs. So it is fine to remove M_PKTHDR on mbufs that have a read-only

Extend the AMD NONARCH method to family 17h. The AMD spec states that for
17h care must be taken when handling sibling threads.

The concern is that if we have a protected two-thread process running on
two siblings, and context switch one thread to another unprotected thread,
disabling the SSB protection on one logical core will disable SSB on its
sibling too (which is still running the protected thread).

All of that doesn't matter to us, because the SSB value we set is

Implement a mitigation for SpectreV4 on AMD families 15h and 16h. We use
a non-architectural MSR. This MSR is also available on 17h, but there SMT
is involved, and it needs more investigation.

Not tested (I have only 10h).

(maxv)

Several changes:

- Move the sysctl initialization code into spectre.c. This way each
  variable is local. Rename the variables, use shorter names.

- Use mitigation methods for SpectreV4, like SpectreV2. There are
  several available on AMD (that we don't support yet). Add a "method"
  leaf.

- Make SSB_NO a mitigation method by itself. This way we report as
  "mitigated" a CPU that is not affected by SpectreV4. In this case,
  of course, the user can't enable/disable the mitigation. Drop the
  "affected" sysctl leaf.

(maxv)

Clarify the parameters for the SpectreV2 mitigation.

Add:
machdep.spectre_v2.swmitigated
Rename:
machdep.spectre_v2.mitigated -> machdep.spectre_v2.hwmitigated

Change the method string, to combine both the hardware and software
mitigations. swmitigated is set at compile time, hwmitigated can be
set by the user.

Examples:

spectre_v2.swmitigated = 1
spectre_v2.hwmitigated = 0
spectre_v2.method = [GCC retpoline]

spectre_v2.swmitigated = 0
spectre_v2.hwmitigated = 0
spectre_v2.method = (none)

spectre_v2.swmitigated = 1
spectre_v2.hwmitigated = 1
spectre_v2.method = [GCC retpoline] + [Intel IBRS]

(maxv)

Add RSBA. When set, it indicates that the CPU is vulnerable to SpectreV2
via the RSB.

(maxv)

Mitigation for SpectreV4, based on SSBD. The following sysctl branches
are added:

machdep.spectre_v4.mitigated = {0/1} user-settable
machdep.spectre_v4.affected = {0/1} set by the kernel

The mitigation is not enabled by default yet. It is not tested either,
because no microcode update has been published yet.

On current CPUs a microcode/bios update must be applied for SSBD to be
available. The user can then set mitigated=1. Even with an update applied
the kernel will set affected=1.

On future CPUs, where the problem will presumably be fixed by default,
the CPU will report SSB_NO, and the kernel will set affected=0. In this
case we also have mitigated=0, but the mitigation is not needed.

For now the feature is system-wide. Perhaps we will want a more
fine-grained, per-process approach in the future.

(maxv)

Reorder and rename, to make the code less SpectreV2-specific.

(maxv)

Remove reference to itself.

Extend ATF tests in t_trapsignal.sh to verify software breakpoint traps

There are at least four types of SIGTRAP events:
- software/hardware single step (trace trap)
- software breakpoint
- hardware breakpoint/watchpoint
- kernel event (exec, fork, vfork, vfork-done, lwp-create, lwp-exit)

A program can execute software breakpoint without the context of being
traced and this is a regular crash signal emitting SIGTRAP (TRAP_BRKPT).

Rename original trap_* tests (trap_simple, trap_handle, trap_mask,
trap_handle_recurse and trap_ignore) to segv_* tests and restrict them for
SIGSEGV.

Add new tests: trap_* testing the same scenarios as segv_ ones, however
verifying the software breakpoint trap (SIGTRAP).

Keep the original name of h_segv.c, and extend it for software breakpoint
events.

The purpose of these tests is to verify SIGTRAP kernel paths without the
ptrace(2) context.

All tests pass.

disable drm2 on modern nouveau cards (Pascal-based).

our older drm doesn't have any support for modern Pascal or
the second version of Maxwell (but not disabled here yet)
but the driver tries to attach on any nvidia gpu.

this should workaround PR#53258, and other issues reported
with modern nvidia chipsets.

Refactor and enable the signal3 ATF ptrace(2) test

Adapt the test to be independent from the software breakpoint trap
behavior, whether the Program Counter is moved or not. Just kill the
process after catching the expected signal, instead of pretending to resume
it.

This test passes.

Also substitute ${X11SRCDIR} for the random seed for reproducible builds so

Update, after ten years. Importantly, add a "History" section, to explain
what's going on.

We have now become "upstream", and most of the ipsec-tools development is
done in NetBSD's CVS. However, many distributions still take their
tarballs from SourceForge (which is defunct, and not maintained).

Make stopsigmask a non-static symbol now as it's used in ptrace(2) code

Fix and enable traceme_signal_nohandler2 in ATF ptrace(2) tests

traceme_signal_nohandler2 checks emitting SIGSTOP to a traced process
with the PT_CONTINUE operation.

The expected behavior is to simulate a behavior of receiving SIGSTOP,
generating SIGCHLD to its parent (in this case the debugger) and ability
to call wait(2)-like function receiving the stopped child event.

The previous behavior was unstopping the process and it has been adjusted
in the kernel code.

FreeBSD keeps unstopping a process for emitting SIGSTOP.
Linux handles this scenario in the same way as NetBSD now.

While there, implement the missing bits in the userland ATF test for
traceme_signal_nohandler2: receiving and validating 2nd SIGSTOP event and
continuing the process, followed by its normal termination.
