e172464728 On amd64 and i386, tell the compiler to refrain from generating SSE,
3DNow, MMX and floating point instructions in rtld-elf.

Otherwise, _rtld_bind() (and whatever it calls) could possibly clobber
function arguments that are passed in SSE/3DNow/MMX/FP registers,
usually floating point values.  This can happen, for example, when clang
generates SSE code for memset() or memcpy() calls.

One symptom of this is sshd dying early on amd64 with "PRNG not seeded",
which is ultimately caused by libcrypto.so.6 calling RAND_add() with a
double parameter.  That parameter is passed via %xmm0, which gets wiped
out by an SSE memset() in _rtld_bind().

ab19dbcf8d Correct an 8-year-old typo which reliably leads to typo after typo today:
The macros here for generating coprocessor 0 accessors are named like:

	MIPS_RDRW32_COP0

That macro would produce mips_rd_<register>() and mips_wr_<register>()
inlines to access the specified register by name from C.  The problem is that
the R and the W were swapped in the macros originally; it was meant to be named
RDWR because it generated mips_rd_* and mips_wr_* functions, but was instead
spelled RDRW, which nobody should be expected to get right by anything other
than copy and paste.

It's too many consonants in a row to keep straight anyway, so just prefer e.g.:

	MIPS_RW32_COP0

While here, add a missing #undef.

192d74107e Partially revert change made in r212061. r212061 relied on
bus_dma(9)'s capability which honors boundary restrictions of DMA
tag for dynamic buffers. However it seems this does not work well
and it triggered watchodg timeouts on controller that has the
hardware bug. It's not clear whether there is still another
hardware bug not mentioned in errata. This should be revisited
since this change shall make use of bounce buffers which in turn
reduces performance a lot on systems that have more than 4GB
memory.

9a264080b5 Remove OCTEON1-32. Since moving to the Cavium SDK, we've lost our support for
running an o32 kernel safely, and would have to add interrupt disabling and
reenabling to a bunch of macros in the Simple Executive sources to support it.

The only reason one would run an o32 kernel on Octeon would be to run o32 world,
which is better worked towards by adding o32 binary compatibility to n64 kernels
along with, eventually, supporting multilib systems so o32 binaries can run
alongside n32 and n64 ones.

aa829cef6a Add hamfisted locking to the Xen/PV pmap code: Only allow one thread to
be in {pmap_pinit, pmap_copy, pmap_release} at a time.

This reduces the rate of panics when running 'make index' from ~0.6/hour
to ~0.02/hour (p < 10^-30).

At a later date this locking will be removed, and for this reason, it is
wrapped in #ifdef HAMFISTED_LOCKING; this temporary hack is being put in
place with the intention of shipping somewhat-stable Xen bits in FreeBSD
8.2-RELEASE.

d01b2dad73 Adjust the critical section protecting _xen_flush_queue to cover the
entire range where the page mapping request queue needs to be atomically
examined and modified.

Oddly, while this doesn't seem to affect the overall rate of panics
(running 'make index' on EC2 t1.micro instances, there are 0.6 +/- 0.1
panics per hour, both before and after this change), it eliminates
vm_fault from panic backtraces, leaving only backtraces going through
vmspace_fork.

e4f64803ab Note compatibility issues with make universe and stable systems. 2011-01-03 23:05:20 +00:00
Warner Losh
92f64fb9e4 When TARGET_ARCH_${kernel} gets set, it is using the host's config,
not the one we build as part of make world.  This means that make
universe will fail if building on a too-old current or any stable
system prior to a few days ago in weird ways (parse errors from
shell).  This copes with these old systems in two ways:

(1) Works around the WARNING: issue by filtering all warnings that
    sneak onto stdout.

(2) if TARGET_ARCH_${kernel} winds up being empty, then we error out
    immediately with a semi-useful error message.  This usually comes from
    config not groking -m.

Ideally, we'd use a buildworld's config here, but that's tricky, so
I'll leave that detail to others to fix (it has to be done post make
world for the arch rather than at the top level makefile).  This
should make 'make universe' usable from recent 8-stable systems
(recent == last few months or so) for building -current.  They have
-m, but spewed warnings out stdout.  Older systems will now at least
get a firm error early rather than a confusing error late.

cefb678553 expand checkuser() to support the propagation of error codes back to
the caller.  Currently, checkuser() does not differentiate between the
failure to open the file and the absence of a user in the file.  Check
to see if there was an error opening the file.  If there are any errors,
terminate the connection.  Currently, the only exception to this rule
is ENOENT, since there is nothing that says the /etc/ftpuser
and /etc/ftpchroot has to exist.

interrupted by a TLB demap IPI, just entering a critical section before
