2cd0384caf Build libstand as a 64-bit library on ppc64
The 32-bit bootloaders now link against libstand.a in sys/boot/libstand32,
so there is no need to force /usr/lib/libstand.a to be 32-bit.

This is equivalent to r261568 for amd64.

5de8a0fdf4 fts: Fix double-free with conflicting concurrent modifications.
If rare conditions such as concurrent conflicting manipulation of the
filesystem occur, fts_read() frees the current FTSENT without adjusting
the pointers in the FTS accordingly. A later fts_close() then frees the
same FTSENT again.

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
the virtio backends.
- 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.

  . Split out a computational kernel,__k_expl(x, &hi, &lo, &k) from expl(x).
    x must be finite and not tiny or huge.  The kernel returns hi and lo
    values for extra precision and an exponent k for a 2**k scale factor.
  . Define additional kernels k_hexpl() and hexpl() that include a 1/2
    scaling and are used by the hyperbolic functions.

* ld80/s_expl.c:
* ld128/s_expl.c:
  . Use the __k_expl() kernel.

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.

4081b25521 Allow building a cross libkvm for ia64. 2013-12-28 23:02:48 +00:00
Marcel Moolenaar
3f6558c489 Allow building a cross libkvm by setting TARGET_ARCH. The library so
produced will be called libkvm-${ARCH} instead of libkvm. This allows
installing it alongside the native version.
For symbol lookups, use ps_pglobal_lookup() instead of __fdnlist()
when building a cross libkvm. It is assumed that the cross tool that
uses the cross libkvm also provides an implementation for this
proc_services function.

Note that this commit does not change any of the architecture-specific
code for cross-compilation.

330baf58c6 Extend the support for local interrupts on the local APIC:
- 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.

07fb02c0d5 Fix an inappropriate free of a non-dynamic value. While here, make the
code more naive and robust:
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".

Trigger case for the bug:
        env_setenv("foo", 0, "1", NULL, NULL);
        env_setenv("foo", 0, "2", NULL, NULL);
