289ccde0bd Correct the handling of NOCLDSTOP when using sigvec()
Make the SA_NODEFER handling more correct, previously if you called
sigaction to set a handler and had SA_NODEFER set, and manually masked
the signal itself in sa_mask, and when you read the settings back later,
you'd find SA_NODEFER incorrectly cleared.

2eb80d36fe Because of the way that ptrace() now calls procfs routines to read/write
the process's memory, it was possible for the procfs_domem() call to
return a residual leftover, but with no errno.  Since this is no good for
ptrace which ignored the the residual, remap a leftover amount into an
errno rather than fooling the caller into thinking it was successful when
in fact it was not.

8fb3332429 Fixed the unit numbers of the devfs `fd' devices.
Made the devfs `fd' devices bug for bug compatible with the ones created
by MAKEDEV:
- ownership is bin.bin, not root.wheel, except for std*.  The devfsext
  interface doesn't seem to allow specifying the ownership of /devfs/fd,
  so it's still incompatible.
- std* aren't links to fd/[0-2].

ede8dc43a2 Fixed unsigned longs that should have been vm_offset_t.
vm_offset_t is currently unsigned long but should probably be plain
unsigned for i386's to match the choice of minimal types to represent
for fixed-width types in Lite2.  Anyway, it shouldn't be assumed
to be unsigned long.

I only fixed the type mismatches that were detected when I changed
vm_offset_t to unsigned.  Only pointer type mismatches were detected.

dedc04fe95 Actually implement SA_RESETHAND - some of the sigaction code recognised it
but didn't actually do anything with it (*blush*).

This should fix bde's test case where the test program set SA_RESETHAND
and when reading it back, it was gone.

Tweak/optimize SA_NODEFER so that the implementation is a little simpler
and does not incur (slight) overhead for every signal at delivery time.

edbfedac86 Import 4.4BSD-Lite2 onto the vendor branch, note that in the kernel, all
files are off the vendor branch, so this should not change anything.

A "U" marker generally means that the file was not changed in between
the 4.4Lite and Lite-2 releases, and does not need a merge.  "C" generally
means that there was a change.
[note new unused (in this form) syscalls.conf, to be 'cvs rm'ed]

be24e9e8fa Changed socket code to use 4.4BSD queue macros. This includes removing
the obsolete soqinsque and soqremque functions as well as collapsing
so_q0len and so_qlen into a single queue length of unaccepted connections.
Now the queue of unaccepted & complete connections is checked directly
for queued sockets. The new code should be functionally equivilent to
the old while being substantially faster - especially in cases where
large numbers of connections are often queued for accept (e.g. http).

e1743d02cd First attempt at FreeBSD & Linux ELF support.
Compile and link a new kernel, that will give native ELF support, and
provide the hooks for other ELF interpreters as well.

To make native ELF binaries use John Polstras elf-kit-1.0.1..
For the time being also use his ld-elf.so.1 and put it in
/usr/libexec.

The Linux emulator has been enhanced to also run ELF binaries, it
is however in its very first incarnation.
Just get some Linux ELF libs (Slackware-3.0) and put them in the
prober place (/compat/linux/...).
I've ben able to run all the Slackware-3.0 binaries I've tried
so far.
(No it won't run quake yet :)

18ff64943e Correct handling of dirty pages in I/O buffers. The case where pages
residing in a buffer that had been dirtied by a process was being
handled incorrectly.  The pages were mistakenly placed into the
cache queue.  This would likely have the effect of mmaped page modifications
being lost when I/O system calls were being used simultaneously to
the same locations in a file.

on in the FreeBSD development, I had made a global lock around the

per resource list basis.  This now allows the rlist code to be used for
almost any non-interrupt level application.

185dc76169 Deal with NetBSD byte-swapped a.out magic when checking the MID to exclude
linux binaries from the *BSD a.out loader. This is a hack, but lets me run
static NetBSD binaries.  Dynamic binaries are a much bigger problem because
the shared libraries would conflict with our native libraries, so a
/compat/netbsd alternate namespace and translation would be needed.
