b3e9732a76 Implement a PCI interrupt router to route PCI legacy INTx interrupts to
the legacy 8259A PICs.
- Implement an ICH-comptabile PCI interrupt router on the lpc device with
  8 steerable pins configured via config space access to byte-wide
  registers at 0x60-63 and 0x68-6b.
- For each configured PCI INTx interrupt, route it to both an I/O APIC
  pin and a PCI interrupt router pin.  When a PCI INTx interrupt is
  asserted, ensure that both pins are asserted.
- Provide an initial routing of PCI interrupt router (PIRQ) pins to
  8259A pins (ISA IRQs) and initialize the interrupt line config register
  for the corresponding PCI function with the ISA IRQ as this matches
  existing hardware.
- Add a global _PIC method for OSPM to select the desired interrupt routing
  configuration.
- Update the _PRT methods for PCI bridges to provide both APIC and legacy
  PRT tables and return the appropriate table based on the configured
  routing configuration.  Note that if the lpc device is not configured, no
  routing information is provided.
- When the lpc device is enabled, provide ACPI PCI link devices corresponding
  to each PIRQ pin.
- Add a VMM ioctl to adjust the trigger mode (edge vs level) for 8259A
  pins via the ELCR.
- Mark the power management SCI as level triggered.
- Don't hardcode the number of elements in Packages in the source for
  the DSDT.  iasl(8) will fill in the actual number of elements, and
  this makes it simpler to generate a Package with a variable number of
  elements.

a9069ffab4 Use the new -d option that was added to tblgen between llvm/clang 3.3
and 3.4 to generate dependency files for the '.inc.h' files generated
from .td files, and .sinclude those dependency files in clang.build.mk.

This will make future incremental builds of lib/clang and usr.bin/clang
work correctly, whenever any of the .td files get modified.

Note that this will not fix any problems with incremental builds from
*before* this revision, since there will not yet be any generated
dependency files.  A quick workaround is to run the following:

  find /usr/obj -type f -name '*.inc.h' | xargs rm

and then a regular incremental buildworld (e.g. with -DNO_CLEAN).

ca5e4fe970 Invalidate the cache for the named posix semaphore when opened and
actual file storing the semaphore object is different from the file
created on the first open.  Store the file st_dev and st_ino members
of the struct stat in the semaphore structure on open, and compare
them with the attributes of the opened file to detect unlink and
re-creation.

This fixes an issue of sem_unlink(3) failing to flush the named entry
in the semaphore list for the current or remote process, making
sem_unlink(3) not correctly operating if the unlinked semaphore is
still opened.

f0fdcfe247 Allow a virtual machine to be forcibly reset or powered off. This is done
by adding an argument to the VM_SUSPEND ioctl that specifies how the virtual
machine should be suspended, viz. VM_SUSPEND_RESET or VM_SUSPEND_POWEROFF.

The disposition of VM_SUSPEND is also made available to the exit handler
via the 'u.suspended' member of 'struct vm_exit'.

This capability is exposed via the '--force-reset' and '--force-poweroff'
arguments to /usr/sbin/bhyvectl.

5280a31478 r261913 broke DES passwords, because the only way they could work,
since they don't have an easily recognizable signature, was if they
were the default.  This commit rewrites crypt_set_format(3) etc to
address this:

 - Use a pointer instead of an index to identify the default format.
   This pointer is initialized at compile time to point to the first
   first element in the list of supported formats, eliminating the
   need for crypt_setdefault().  Using a pointer also simplifies
   iterating through the list.

 - Associate DES with the magic string "_", which takes care of the
   Extended DES format.

 - Finally, as a special case, if the salt does not match any known
   magic string but matches ^[./0-9A-Za-z]{13}$, it is assumed to be a
   DES password and is passed on to crypt_des().

Ed Schouten
38219d6acd Implement kqueue(2) for procdesc(4).
kqueue(2) already supports EVFILT_PROC. Add an EVFILT_PROCDESC that
behaves the same, but operates on a procdesc(4) instead. Only implement
NOTE_EXIT for now. The nice thing about NOTE_EXIT is that it also
returns the exit status of the process, meaning that we can now obtain
this value, even if pdwait4(2) is still unimplemented.

Notes:

- Simply reuse EVFILT_NETDEV for EVFILT_PROCDESC. As both of these will
  be used on totally different descriptor types, this should not clash.

- Let procdesc_kqops_event() reuse the same structure as filt_proc().
  The only difference is that procdesc_kqops_event() should also be able
  to deal with the case where the process was already terminated after
  registration. Simply test this when hint == 0.

- Fix some style(9) issues in filt_proc() to keep it consistent with the
  newly added procdesc_kqops_event().

- Save the exit status of the process in pd->pd_xstat, as we cannot pick
  up the proctree_lock from within procdesc_kqops_event().

4ed06f2924 Accept RFC 2292 option values so that RFC 2292 compliant programs that
are unaware of RFC 3542 can construct control messages.

The kernel disallows mixing RFC 2292 behaviour with RFC 3542 behaviour.
Only sockets that have specifically been marked as using the RFC 2292
API can use RFC 2292 specific options. This is all good and well, but
libc itself seems inconsistent with this.

The root cause of this inconsistency seems to relate to the definitions
of IPV6_HOPOPTS and IPV6_DSTOPTS. They are defined in RFC 2292 and re-used
in RFC 3542, yet have distinct values in the kernel. It's for this reason
that the kernel also has definitions for IPV6_2292HOPOPTS and
IPV6_2292DSTOPTS. Not so in libc.

For example: some program calls inet6_option_init() (defined by RFC 2292)
with the RFC 2292 defined IPV6_HOPOPTS and IPV6_DSTOPTS. Before RFC 3542,
this was translated to values of 22 and 23 (resp.) The libc implementation
correctly checks that only options IPV6_HOPOPTS and IPV6_DSTOPTS are given
(as per RFC 2292) but since these defines have taken on the values defined
by RFC 3542 (values 49 and 50 resp,) rejects the correct option values
(22 and 23) passed said program and returns -1.

The precisie fix is to have inet6_option_init() and friends only accept the
RFC 2292 defined IPV6_HOPOPTS & IPV6_DSTOPTS, but that breaks other code
(like mld6query(8)), which seem to not be aware of RFC 3542 and how it
hi-jacked the option names. So the best fix is to accept the options from
both.

b15a09c05e Add an ioctl to suspend a virtual machine (VM_SUSPEND). The ioctl can be called
from any context i.e., it is not required to be called from a vcpu thread. The
ioctl simply sets a state variable 'vm->suspend' to '1' and returns.

The vcpus inspect 'vm->suspend' in the run loop and if it is set to '1' the
vcpu breaks out of the loop with a reason of 'VM_EXITCODE_SUSPENDED'. The
suspend handler waits until all 'vm->active_cpus' have transitioned to
'vm->suspended_cpus' before returning to userspace.

54ff5d7323 Add a SUBDIR_PARALLEL option to bsd.subdir.mk, to allow make to process
all the SUBDIR entries in parallel, instead of serially.  Apply this
option to a selected number of Makefiles, which can greatly speed up the
build on multi-core machines, when using make -j.

This can be extended to more Makefiles later on, whenever they are
verified to work correctly with parallel building.

I tested this on a 24-core machine, with make -j48 buildworld (N = 6):

                before    stddev       after    stddev
                =======   ======       =======  ======
real time        1741.1     16.5         959.8     2.7
user time       12468.7     16.4       14393.0    16.8
sys  time        1825.0     54.8        2110.6    22.8

(user+sys)/real     8.2                   17.1

E.g. the build was approximately 45% faster in real time.  On machines
with less cores, or with lower -j settings, the speedup will not be as
impressive.  But at least you can now almost max out a machine with
buildworld!

73279d4113 Add a new ARM TARGET_ARCH, armv6hf. This is considered experimental.
This targets the existing ARMv6 and ARMv7 SoCs that contain a VFP unit.
This is an optional coprocessors may not be present in all devices, however
it appears to be in all current SoCs we support.

armv6hf targets the VFP variant of the ARM EABI and our copy of gcc is too
old to support this. Because of this there are a number of WITH/WITHOUT
options that are unsupported and must be left as the default value. The
options and their required value are:
 * WITH_ARM_EABI
 * WITHOUT_GCC
 * WITHOUT_GNUCXX

In addition, without an external toolchain, the following need to be left
as their default:
 * WITH_CLANG
 * WITH_CLANG_IS_CC

As there is a different method of passing float and double values to
functions the ABI is incompatible with existing armv6 binaries. To use
this a full rebuild of world is required. Because no floating point values
are passed into the kernel an armv6 kernel with VFP enabled will work with
an armv6hf userland and vice versa.

8083f14fc2 replace the kernel's version w/ cperciva's implementation... In all
my tests, it is faster ~20%, even on an old IXP425 533MHz it is ~45%
faster...  This is partly due to loop unrolling, so the code size does
significantly increase...  I do plan on committing a version that
rolls up the loops again for smaller code size for embedded systems
where size is more important than absolute performance (it'll save ~6k
code)...

The kernel implementation is now shared w/ userland's libcrypt and
libmd...

We drop support for sha256 from sha2.c, so now sha2.c only contains
sha384 and sha512...

f5fd950e35 Make bsd.test.mk the only public mk fragment for the building of tests.
Change {atf,plain,tap}.test.mk to be internal implementation details of
bsd.test.mk.  Makefiles that build tests should now only include bsd.test.mk
and declaratively specify what they want to build, without worrying about
the internal implementation of the mk files.

The reason for this change is to permit building test programs of different
interfaces from a single directory, which is something I had a need for
while porting tests over from src/tools/regression/.

Additionally, this change makes it possible to perform some other requested
changes to bsd.test.mk in an easier manner.  Coming soon.

IPX was a network transport protocol in Novell's NetWare network operating
system from late 80s and then 90s. The NetWare itself switched to TCP/IP
as default transport in 1998. Later, in this century the Novell Open
Enterprise Server became successor of Novell NetWare. The last release
that claimed to still support IPX was OES 2 in 2007. Routing equipment
vendors (e.g. Cisco) discontinued support for IPX in 2011.

Thus, IPX won't be supported in FreeBSD 11.0-RELEASE.

76a1f42f3f Make ether_line really report an error when all input is invalid.
The previous code failed to return an error condition when the whole input
was invalid due to improper handling of the sscanf return value.  Actually,
this failure was properly being caught by a test in
tools/regression/lib/libc/net/test-ether.t but was not noticed because
these tests are never run.  (On my way to fixing that ;-)

The fix applied here resembles the implementation of ether_line in NetBSD
modulo the setting of an errno value (which is not documented as an
expectation in the manpage anyway).

dc50650607 Queue pending exceptions in the 'struct vcpu' instead of directly updating the
processor-specific VMCS or VMCB. The pending exception will be delivered right
before entering the guest.

The order of event injection into the guest is:
- hardware exception
- NMI
- maskable interrupt

In the Intel VT-x case, a pending NMI or interrupt will enable the interrupt
window-exiting and inject it as soon as possible after the hardware exception
is injected. Also since interrupts are inherently asynchronous, injecting
them after the hardware exception should not affect correctness from the
guest perspective.

Rename the unused ioctl VM_INJECT_EVENT to VM_INJECT_EXCEPTION and restrict
it to only deliver x86 hardware exceptions. This new ioctl is now used to
inject a protection fault when the guest accesses an unimplemented MSR.

f785676f2a Upgrade our copy of llvm/clang to 3.4 release. This version supports
all of the features in the current working draft of the upcoming C++
standard, provisionally named C++1y.

The code generator's performance is greatly increased, and the loop
auto-vectorizer is now enabled at -Os and -O2 in addition to -O3.  The
PowerPC backend has made several major improvements to code generation
quality and compile time, and the X86, SPARC, ARM32, Aarch64 and SystemZ
backends have all seen major feature work.

b1526b43e8 Set the malloc alignment to 64 bytes on platforms that use the U-Boot API
device drivers.  Recent versions of u-boot run with the MMU enabled, and
require DMA-based I/O to be aligned to cache line boundaries.

These changes are based on a patch originally submitted by Juergen Weiss,
but I reworked them and thus any problems are purely my fault.

00f3efe1bd Add support for FreeBSD/i386 guests under bhyve.
- Similar to the hack for bootinfo32.c in userboot, define
  _MACHINE_ELF_WANT_32BIT in the load_elf32 file handlers in userboot.
  This allows userboot to load 32-bit kernels and modules.
- Copy the SMAP generation code out of bootinfo64.c and into its own
  file so it can be shared with bootinfo32.c to pass an SMAP to the i386
  kernel.
- Use uint32_t instead of u_long when aligning module metadata in
  bootinfo32.c in userboot, as otherwise the metadata used 64-bit
  alignment which corrupted the layout.
- Populate the basemem and extmem members of the bootinfo struct passed
  to 32-bit kernels.
- Fix the 32-bit stack in userboot to start at the top of the stack
  instead of the bottom so that there is room to grow before the
  kernel switches to its own stack.
- Push a fake return address onto the 32-bit stack in addition to the
  arguments normally passed to exec() in the loader.  This return
  address is needed to convince recover_bootinfo() in the 32-bit
  locore code that it is being invoked from a "new" boot block.
- Add a routine to libvmmapi to setup a 32-bit flat mode register state
  including a GDT and TSS that is able to start the i386 kernel and
  update bhyveload to use it when booting an i386 kernel.
- Use the guest register state to determine the CPU's current instruction
  mode (32-bit vs 64-bit) and paging mode (flat, 32-bit, PAE, or long
  mode) in the instruction emulation code.  Update the gla2gpa() routine
  used when fetching instructions to handle flat mode, 32-bit paging, and
  PAE paging in addition to long mode paging.  Don't look for a REX
  prefix when the CPU is in 32-bit mode, and use the detected mode to
  enable the existing 32-bit mode code when decoding the mod r/m byte.

3cbf3585cb Enhance the support for PCI legacy INTx interrupts and enable them in

- Add a new ioctl to export the count of pins on the I/O APIC from vmm
  to the hypervisor.
- Use pins on the I/O APIC >= 16 for PCI interrupts leaving 0-15 for
  ISA interrupts.
- Populate the MP Table with I/O interrupt entries for any PCI INTx
  interrupts.
- Create a _PRT table under the PCI root bridge in ACPI to route any
  PCI INTx interrupts appropriately.
- Track which INTx interrupts are in use per-slot so that functions
  that share a slot attempt to distribute their INTx interrupts across
  the four available pins.
- Implicitly mask INTx interrupts if either MSI or MSI-X is enabled
  and when the INTx DIS bit is set in a function's PCI command register.
  Either assert or deassert the associated I/O APIC pin when the
  state of one of those conditions changes.
- Add INTx support to the virtio backends.
- Always advertise the MSI capability in the virtio backends.

9c1ca3a1dd r261230 broke the cases where the amount of data to be read is not
known in advance, or where the caller doesn't care and just keeps
reading until it hits EOF.

In fetch_read(): the socket is non-blocking, so read() will return 0
on EOF, and -1 (errno == EAGAIN) when the connection is still open but
there is no data waiting.  In the first case, we should immediately
return 0.  The EINTR case was also broken, although not in a way that
matters.

In fetch_writev(): use timersub() and timercmp() as in fetch_read().

In http_fillbuf(): set errno to a sensible value when an invalid chunk
header is encountered.

In http_readfn(): as in fetch_read(), a zero return from down the
stack indicates EOF, not an error.  Furthermore, when io->error is
EINTR, clear it (but no errno) before returning so the caller can
retry after dealing with the interrupt.

215a27f1a4 Solve http buffering issues and hangs once and for all (hopefully!) by
simply not trying to return exactly what the caller asked for - just
return whatever we got and let the caller be the judge of whether it
was enough.  If an error occurs or the connection times out after we
already received some data, return a short read, under the assumption
that the next call will fail or time out before we read anything.

As it turns out, none of the code that calls fetch_read() assumes an
all-or-nothing result anyway, except for a couple of lines where we
read the CR LF at the end of a hunk in HTTP hunked encoding, so the
changes outside of fetch_read() and http_readfn() are minimal.

While there, replace select(2) with poll(2).

f864e2ab73 Re-apply the part of r260022 that was reverted by r260030 with
one significant difference: for LIB32 builds both TARGET_ARCH
and MACHINE_ARCH are defined. TARGET_ARCH confusingly holds the
architecture of the host (e.g. amd64), while MACHINE_ARCH holds
the architecture were trying to build (e.g. i386). With both
set and different, r260022 changed the behaviour to interpret
the condition as building a cross-amd64 libkvm on i386, when
obviously we're trying to build an i386 version on amd64. When
COMPAT_32BIT is defined, we're building LIB32 and ignore the
value of TARGET_ARCH as we did before.

5f96573141 Add support for virtual cores (aka minidumps). To that end, refactor this
file as follows:
1.  Common ia64-specific support functions have the ia64_ prefix.
2.  Functions that work on physical cores have the phys_ prefix.
3.  Functions that work on virtual cores have the virt_ prefix.

With that:
1.  _kvm_kvatop() has been renamed to phys_kvatop() as it handles
    physical cores only.
2.  The new _kvm_kvatop() is nothing but a wrapper that calls either
    phys_kvatop() or virt_kvatop() by virtue of the kvatop function
    pointer in the vmstate structure.
3.  virt_kvatop() is nothing but a wrapper around virt_addr2off().
4.  virt_addr2off() iterates over the Phdrs to find the segment in
    which the address falls and return the file offset for it.

Now it's up to the kernel to populate the core file appropriately.

- Add a generic routine to trigger an LVT interrupt that supports both
  fixed and NMI delivery modes.
- Add an ioctl and bhyvectl command to trigger local interrupts inside a
  guest.  In particular, a global NMI similar to that raised by SERR# or
  PERR# can be simulated by asserting LINT1 on all vCPUs.
- Extend the LVT table in the vCPU local APIC to support CMCI.
- Flesh out the local APIC error reporting a bit to cache errors and
  report them via ESR when ESR is written to.  Add support for asserting
  the error LVT when an error occurs.  Raise illegal vector errors when
  attempting to signal an invalid vector for an interrupt or when sending
  an IPI.
- Ignore writes to reserved bits in LVT entries.
- Export table entries the MADT and MP Table advertising the stock x86
  config of LINT0 set to ExtInt and LINT1 wired to NMI.

1.  When setting ev_value, also always set ev_flags appropriately
2.  Always check ev_value and ev_flags before calling free.

Both the value and the EV_DYNAMIC property can come directly from the
consumers of the environment functionality, so it's good to be careful.
And since this code is typically not looked at for long periods of
time, it's good to have it be a little "dumb-looking".

Running them makes the destruction order wrong, and there is hope that
such destructors would not call dlclose(3), since it is pointless at
this stage of the process existence.

The change effectively disables the r211706 after the exit(3) is

7c5b23111c Add ICONV_{GET,SET}_ILSEQ_INVALID iconvctl. GNU iconv returns EILSEQ
when there is an invalid character in the output codeset while it is
valid in the input.  However, POSIX requires iconv() to perform an
implementation-defined conversion on the character.  So, Citrus iconv converts
such a character to a special character which means it is invalid in the
output codeset.

This is not a problem in most cases but some software like libxml2 depends
on GNU's behavior to determine if a character is output as-is or another form
such as a character entity (&#NNN;).

0a9655a082 If check_deferred_signal() execution needs binding of PLT symbol,
unlocking the rtld bind lock results in the processing of ast and
recursing into the check_deferred_signal().  Nested execution of
check_deferred_signal() delivers the signal to user code and clears
si_signo.  On return, top-level check_deferred_signal() frame
continues delivering the same signal one more time, but now with zero
si_signo.

Fix this by adding a flag to indicate that deferred delivery is
running, so check_deferred_signal() should avoid doing anything. Since
user signal handler is allowed to modify the passed machine context to
make return from the signal handler to cause arbitrary jump, or do
longjmp(). For this case, also clear the flag in thr_sighandler(),
since kernel signal delivery means that nested delivery code should
not run right now.

204957ef5e Bug fixes in iconv(3) UTF-7 support.
- Add ' to the list of directly encoded characters and * to the list of
  optionally directly encoded characters as per RFC 2152.

- In _citrus_UTF7_mbtoutf16 on end of input when the next output character
  has only been partially decoded, save a copy of the buffer of input
  characters (not just its length).  On the next call with more input
  characters this buffer is reprocessed together with the new input to
  form a fully decoded output character.

- At the end of a base64 encoded sequence fully discard '-' (BASE64_OUT)
  by decrementing psenc->chlen and i.  This is needed to make room in
  psenc->ch (input buffer) in case the next input character starts a new
  base64 encoded sequence.  And also, if this is the end of input and no
  output character can be returned, this brings the encoder in the initial
  state as indicated by _citrus_UTF7_stdenc_get_state_desc_generic which
  is used by the caller to distinguish between no output and partial
  output.

- In _citrus_UTF7_mbrtowc_priv pass the s parameter (input pointer)
  directly to _citrus_UTF7_mbtoutf16 instead of a copy (s0).  This way s
  is updated correctly in case of errors.

- In _citrus_UTF7_mbrtowc_priv when called with psenc->surrogate set
  (previous call did not have enough input), retrieve the previously
  decoded UTF-16 character from (psenc->cache >> psenc->bits) instead of
  (psenc->cache >> 2).

615dc002b8 Fix the build of some ATF tests.
When building various programs from a single Makefile, program-specific
variables are of the form <VAR>.<PROG>, not <VAR>_<PROG>.  Fix this
obvious typo to fix the build when WITH_TESTS=yes.

I am not sure how this ever worked before given that manual inspection
of bsd.progs.mk clearly shows that the expected character between the
two components is a dot and not an underscore... but I suspect the
changes in r258095 exposed this oddity.

091b8336ae Attempt to move the POSIX iconv* symbols out of runtime linker space.
FreeBSD systems usually implemented this as a third party module and
our implementation hasn't played as nicely with the old way as it could
have.

To that end:
* Rename the iconv* symbols in libc.so.7 to have a __bsd_ prefix.
* Provide .symver compatability with existing 10.x+ binaries that
  referenced the iconv symbols. All existing binaries should work.
* Like on Linux/glibc systems, add a libc_nonshared.a to the ldscript
  at /usr/lib/libc.so.
* Move the "iconv*" wrapper symbols to libc_nonshared.a

This should solve the runtime ambiguity about which symbols resolve
to where.  If you compile against the iconv in libc, your runtime
dependencies will be unambiguous.

Old 9.x libraries and binaries will always resolve against their
libiconv.so.3 like they did on 9.x.  They won't resolve against libc.

Old 10.x binaries will be satisified by the .symver helpers.

This should allow ports to selectively compile against the libiconv
port if needed and it should behave without ambiguity now.

cc21b86f50 Install category Kyuafiles from their category directories.
Move the installation of /usr/tests/lib/Kyuafile from src/tests/lib/
to src/lib/.  This is to keep the src/tests/ hierarchy unaware of the
rest of the tree, which makes things clearer in general.  In particular:

1) Everything related to the construction of /usr/tests/lib/ is kept
   in src/lib/.  There is no need to think about different directories
   and how they relate to each other.  (The same applies for libexec,
   usr.bin, etc. but these are not yet handled.)

2) src/tests becomes the place to keep cross-functional test programs
   and nothing else, which also helps in simplifying things.
