4e397bc524 In tcp_ctloutput(), don't hold the inpcb lock over a call to
ip_ctloutput(), as it may need to perform blocking memory allocations.
This also improves consistency with locking relative to other points
that call into ip_ctloutput().

8e1b797456 Add a sysctl/tunable, "kern.always_console_output", that lets you set
output to permanently (not ephemerally) go to the console.  It is also
sent to any other console specified by TIOCCONS as normal.

While I'm here, document the kern.log_console_output sysctl.

e1e6143854 Check if ${_dir}/kern exists as well, because if it doesn't exists
we will fail later and we can miss good kernel source tree directory.
I found this trying to compile kld module and it finds 'conf/kmod.mk'
in '../..', but it fails later, because there is no 'kern' directory,
but there is valid kernel source tree still in /usr/src/sys/.

a5de0db8b5 Try harder to give new processes a clean initial fpu state. fpu_cleanstate
wasn't actually clean, it was saving the xmm registers as left over by the
bios.  fninit() doesn't clear those.

In fpudna(), instead of doing a fninit() and forgetting to load the initial
mxcsr, do a full fxrstor(&fpu_cleanstate).  Otherwise we hand over whatever
random values are left in the xmm registers by the last user.

I'm not certain of whether this is excessive paranoia or not, but there was
an outright bug in neglecting to set the mxcsr value that caused awk to
SIGFPE in some case.  Especially for Tim Robbins. :-)

i386 probably should do something about the mxcsr setings too.

c012260726 Merge some additional leaf node socket buffer locking from
rwatson_netperf:

Introduce conditional locking of the socket buffer in fifofs kqueue
filters; KNOTE() will be called holding the socket buffer locks in
fifofs, but sometimes the kqueue() system call will poll using the
same entry point without holding the socket buffer lock.

Introduce conditional locking of the socket buffer in the socket
kqueue filters; KNOTE() will be called holding the socket buffer
locks in the socket code, but sometimes the kqueue() system call
will poll using the same entry points without holding the socket
buffer lock.

Simplify the logic in sodisconnect() since we no longer need spls.

NOTE: To remove conditional locking in the kqueue filters, it would
make sense to use a separate kqueue API entry into the socket/fifo
code when calling from the kqueue() system call.

bd1a3f1a7e Fixed a panic caused by over-optimizing npxdrop() in the non-FXSR case.
frstor can trap despite it being a control instruction, since it bogusly
checks for pending exceptions in the state that it is overwriting.
This used to be a non-problem because frstor was always paired with a
previous fnsave, and fnsave does an implicit fninit so any pending
exceptions only remain live in the saved state.  Now frstor is sometimes
paired with npxdrop() and we must do a little more than just forget
that the npx was used in npxdrop() to avoid a trap later.  This is a
non-problem in the FXSR case because fxrstor doesn't do the bogus check.

FXSR is part of SSE, and npxdrop() is only in FreeBSD-5.x, so this bug
only affected old machines running FreeBSD-5.x.

d05bb9a2a6 Fix the problem that surfaced with the new binutils import on sparc64
(and that is for now being worked around by a binutils patch).

The rtld code tested &_DYNAMIC against 0 to see whether rtld itself
was built as PIC or not. While the sparc64 MD code did not rely
on the preset value of the GOT slot for _DYNAMIC any more due
to previous binutils changes, it still used to not be 0, so
that this check did work. The new binutils do however initialize
this slot with 0. As a consequence, rtld would not properly initialize
itself and crash.
Fix that by introducing a new macro, RTLD_IS_DYNAMIC, to take the role
of this test. For sparc64, it is implemented using the rtld_dynamic()
code that was already there. If an architecture does not provide its
own implementation, we default to the old check.

While being there, mark _DYNAMIC as a weak symbol in the sparc64
rtld_start.S. This is needed in the LDSCRIPT case, which is however
not currently supported for want of an actual ldscript.

Sanity checked with md5 on alpha, amd64, i386 and ia64.

7ca59a8f46 Forced commit to note that the hack removed in the previous commit
really used to be necessary.  bus_teardown_interrupt() was completely
broken for fast interrupts in -current from approx. 2001/02/09 to
2003/11/03.  It not only didn't shut down the hardware interrupt; it
also left the fast interrupt handler wired into the IDT.  The hack was
needed to shut down the hardware interrupt.  Without it, for npx,
unmasked exceptions were delivered via both IRQ13 and Exception16, and
spurious IRQ13 broke exception handling in much the same way that it
is broken on old systems that don't support Exception16.

- Lock down low hanging fruit use of so_state with socket lock.

- Lock down low hanging fruit use of so_options.

- Lock down low-hanging fruit use of sb_lowwat and sb_hiwat with

- Annotate situations in which we unlock the socket lock and then
  grab the receive socket buffer lock, which are currently actually
  the same lock.  Depending on how we want to play our cards, we
  may want to coallesce these lock uses to reduce overhead.

- Convert a if()->panic() into a KASSERT relating to so_state in
  soaccept().

- Remove a number of splnet()/splx() references.

More complex merging of socket and socket buffer locking to
follow.
