Fix incorrect parsing: the R/M field uses a special GPR map when the
address size is 16 bits, regardless of the actual operating mode. With
this special map there can be two registers referenced at once, and
also disp16-only.
Implement this special behavior, and add associated tests. While here
simplify a few things.
With this in place, the Windows 95 installer initializes correctly.
Part of PR/54611.
add missing initializer
Implement XCHG, add associated tests, and add comments to explain. With
this in place the Windows 95 installer completes successfuly.
Part of PR/54611.
Improve nvmm_vcpu_dump().
Put back 'default', because llvm apparently doesn't realize that all cases
are covered in the switch.
Miscellaneous changes in NVMM, to address several inconsistencies and
issues in the libnvmm API.
- Rename NVMM_CAPABILITY_VERSION to NVMM_KERN_VERSION, and check it in
  libnvmm. Introduce NVMM_USER_VERSION, for future use.
- In libnvmm, open "/dev/nvmm" as read-only and with O_CLOEXEC. This is to
  avoid sharing the VMs with the children if the process forks. In the
  NVMM driver, force O_CLOEXEC on open().
- Rename the following things for consistency:
      nvmm_exit*              -> nvmm_vcpu_exit*
      nvmm_event*            -> nvmm_vcpu_event*
      NVMM_EXIT_*            -> NVMM_VCPU_EXIT_*
      NVMM_EVENT_INTERRUPT_HW -> NVMM_VCPU_EVENT_INTR
      NVMM_EVENT_EXCEPTION    -> NVMM_VCPU_EVENT_EXCP
  Delete NVMM_EVENT_INTERRUPT_SW, unused already.
- Slightly reorganize the MI/MD definitions, for internal clarity.
- Split NVMM_VCPU_EXIT_MSR in two: NVMM_VCPU_EXIT_{RD,WR}MSR. Also provide
  separate u.rdmsr and u.wrmsr fields. This is more consistent with the
  other exit reasons.
- Change the types of several variables:
      event.type                  enum -> u_int
      event.vector                uint64_t -> uint8_t
      exit.u.*msr.msr:            uint64_t -> uint32_t
      exit.u.io.type:            enum -> bool
      exit.u.io.seg:              int -> int8_t
      cap.arch.mxcsr_mask:        uint64_t -> uint32_t
      cap.arch.conf_cpuid_maxops: uint64_t -> uint32_t
- Delete NVMM_VCPU_EXIT_MWAIT_COND, it is AMD-only and confusing, and we
  already intercept 'monitor' so it is never armed.
- Introduce vmx_exit_insn() for NVMM-Intel, similar to svm_exit_insn().
  The 'npc' field wasn't getting filled properly during certain VMEXITs.
- Introduce nvmm_vcpu_configure(). Similar to nvmm_machine_configure(),
  but as its name indicates, the configuration is per-VCPU and not per-VM.
  Migrate and rename NVMM_MACH_CONF_X86_CPUID to NVMM_VCPU_CONF_CPUID.
  This becomes per-VCPU, which makes more sense than per-VM.
- Extend the NVMM_VCPU_CONF_CPUID conf to allow triggering VMEXITs on
  specific leaves. Until now we could only mask the leaves. An uint32_t
  is added in the structure:
        uint32_t mask:1;
        uint32_t exit:1;
        uint32_t rsvd:30;
  The two first bits select the desired behavior on the leaf. Specifying
  zero on both resets the leaf to the default behavior. The new
  NVMM_VCPU_EXIT_CPUID exit reason is added.
Three changes in libnvmm:
- Add 'mach' and 'vcpu' backpointers in the nvmm_io and nvmm_mem
  structures.
- Rename 'nvmm_callbacks' to 'nvmm_assist_callbacks'.
- Rename and migrate NVMM_MACH_CONF_CALLBACKS to NVMM_VCPU_CONF_CALLBACKS,
  it now becomes per-VCPU.
Update the libnvmm man page:
- Sync the naming with reality.
- Replace "relevant" by "desired" and "virtualizer" by "emulator", closer
  to what I meant.
- Add a "VCPU Configuration" section.
- Add a "Machine Ownership" section.
Add the "nvmm" group, and make nvmm_init() public. Sent to tech-kern@ a few
days ago.
Use the new PTE naming, and define CR3_FRAME_* separately. No functional
change.
Add a new VCPU conf option, that allows userland to request VMEXITs after a
TPR change. This is supported on all Intel CPUs, and not-too-old AMD CPUs.
The reason for wanting this option is that certain OSes (like Win10 64bit)
manage interrupt priority in hardware via CR8 directly, and for these OSes,
the emulator may want to sync its internal TPR state on each change.
Add two new fields in cap.arch, to report the conf capabilities. Report TPR
only on Intel for now, not AMD, because I don't have a recent AMD CPU on
which to test.
Mask CPUID leaf 0x0A on Intel, because we don't want the guest to try (and
fail) to probe the PMC MSRs. This avoids "Unexpected WRMSR" warnings in
qemu-nvmm.
Add PCID support in the guests. This speeds up most 64bit guests, because
since Meltdown, everybody uses PCID (including NetBSD).
Change the way root_owner works: consider the calling process as root_owner
not if it has root privileges, but if the /dev/nvmm device was opened with
write permissions. Introduce the undocumented nvmm_root_init() function to
achieve that.
The goal is to simplify the logic and have more granularity, eg if we want
a monitoring agent to access VMs but don't want to give this agent real
root access on the system.
A few changes:
- Use smaller types in struct nvmm_capability.
- Use smaller type for nvmm_io.port.
- Switch exitstate to a compacted structure.
Add nram in struct nvmm_ctl_mach_info.
Add nvmmctl, with two commands for now.
Macro tidyness.
Sort SEE ALSO.
should be fork(2), noticed by wiz
Add debug entry for newly introduced nvmmctl utility.
Annotate a covering switch as such to avoid warnings about missing
returns.
Forgot to put nvmmctl in the "nvmm" group.
Add nvmm group.

Preserve the LWP ID of the calling thread on (v)fork. This ensures that
_lwp_self() remains invariant as necessary for the locking in the
dynamic linker. Otherwise if a process creates a thread and forks from
it, the main thread of the parent would share the LWP ID of the main
thread of the child, even though they have different origins.

Ensure in validate_label() that struct disklabel pointer is 8-byte aligned

The label is searched each 4 bytes and can be detected in an unaligned
location. Before any operations on it, copy it to promptly aligned local
copy on the stack.

This is a missing part of the following change:

revision 1.108
date: 2011-01-18 20:52:24 +0100;  author: matt;  state: Exp;  lines: +2 -1;
Make struct disklabel 8 byte aligned.  This increases its size by 4 bytes
on IPL32 platforms so add code in sys_ioctl (and netbsd32_ioctl) to deal
with the older/smaller diskabel size.  This change makes disklabel the
same for both IPL32 and LP64 platforms

Arm DMA tags with _nranges=0 require no address translation. Handle this

revert the powerpc config.gcc changes i made while merging,
they end up mis-ordering tm files.

revert the rs6000/netbsd64.h change and put it back as
SUBSUBTARGET_EXTRA_SPECS.

this seems to make the build work again, though mknative will
need a re-run for ppc*.

Add Kernel Concurrency Sanitizer (kCSan) support. This sanitizer allows us
to detect race conditions at runtime. It is a variation of TSan that is
easy to implement and more suited to kernel internals, albeit theoretically
less precise than TSan's happens-before.

We do basically two things:

- On every KCSAN_NACCESSES (=2000) memory accesses, we create a cell
  describing the access, and delay the calling CPU (10ms).

- On all memory accesses, we verify if the memory we're reading/writing
  is referenced in a cell already.

The combination of the two means that, if for example cpu0 does a read that
is selected and cpu1 does a write at the same address, kCSan will fire,
because cpu1's write collides with cpu0's read cell.

The coverage of the instrumentation is the same as that of kASan. Also, the
code is organized in a way similar to kASan, so it is easy to add support
for more architectures than amd64. kCSan is compatible with KCOV.

- Use EXTRA_SPECS like we did for aarch64 instead of SUBSUBTARGET_EXTRA_SPECS
  so that assembly specs get propagated (they were lost before)
