effcb5eca3 Change gethostname() to set errno to ENAMETOOLONG instead of ENOMEM
when the buffer is not long enough to hold the current host name.
POSIX does not standardize error returns for gethostname(), so it
doesn't matter which one we use, but ENAMETOOLONG is at least a little
more intuitive, and mi suggests the existence of prior art.  I've been
running with this change for a while on my home machine with no
effect.  At the same time, I've updated the prototype for
gethostname() to use the correct standard type (size_t) for the
namelen argument.

All of the in-tree callers fall into one of the following categories:
1) Call perror() or equivalent when gethostname() fails.
2) Ignore gethostname()'s return value entirely, potentially resulting
in data corruption if the buffer is too small.
3) Fall back to a (possibly sensible) default value if gethostname()
fails.

Many of the callers I examined shows signs of confusion about the
correct sizing of the host name buffer.  gethostname(3) now has more
information about this, as well as updated standards information.

abd498aa71 Add the mlockall() and munlockall() system calls.
- All those diffs to syscalls.master for each architecture *are*
   necessary. This needed clarification; the stub code generation for
   mlockall() was disabled, which would prevent applications from
   linking to this API (suggested by mux)
 - Giant has been quoshed. It is no longer held by the code, as
   the required locking has been pushed down within vm_map.c.
 - Callers must specify VM_MAP_WIRE_HOLESOK or VM_MAP_WIRE_NOHOLES
   to express their intention explicitly.
 - Inspected at the vmstat, top and vm pager sysctl stats level.
   Paging-in activity is occurring correctly, using a test harness.
 - The RES size for a process may appear to be greater than its SIZE.
   This is believed to be due to mappings of the same shared library
   page being wired twice. Further exploration is needed.
 - Believed to back out of allocations and locks correctly
   (tested with WITNESS, MUTEX_PROFILING, INVARIANTS and DIAGNOSTIC).

didn't provide a constant for one of them (non-IEEE denormal trap),

o Properly mask the passed or returned fp_except_t. Not doing so

8955f59879 Override the default stubs for getcontext(2) and swapcontext(2) so
that we can flush the register stack prior to entering the kernel.
This avoids having dirty registers and saves us from having to
manually write them to the backing store from within the kernel.
In that respect, flushing the RSE is both functionally required as
well as performance optimal.

On average we had 18 dirty registers when getcontext(2) was called
from libthr. Since libthr does not switch back to a context created
by getcontext(2), not having dealt with the dirty registers was
harmless.

55e24f6e77 Document an additional error return value. The connect(2) call can also

following program:

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <errno.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>

int
main(int argc, char *argv[])
{
	struct sockaddr_in rem_addr;
	int sock;

	if ((sock = socket(AF_INET, SOCK_STREAM, 0)) < 0) {
		perror("socket");
		exit(1);
	}

	bzero((char *)&rem_addr, sizeof(rem_addr));
	rem_addr.sin_family = AF_INET;
	rem_addr.sin_addr.s_addr = INADDR_NONE;
	rem_addr.sin_port = htons(10000);

	if (connect(sock, (struct sockaddr *)&rem_addr,
sizeof(rem_addr)) < 0) {
		perror("connect");
		exit(1);
	}
}

The call chain returning this value is probably:

kern/uipc_syscalls.c:connect
kern/uipc_socket.c:soconnect
netinet/tcp_usrreq.c:tcp_usr_connect
netinet/tcp_output.c:tcp_output

0287aa1cee Revert to using yp_order() to probe for master.paswd.by* maps and
don't probe the server at all for passwd.by* maps. This fixes
interoperability with the Services For UNIX NIS server (which is
really a front end to Captive^WActiveDirectory). This server
incorrectly returns success for all YPPROC_MASTER requests,
even for maps that don't exist, which makes it impossible to
(ab)use it to probe for the existence of the master.passwd.by*
maps.

This is a little kludgey, but basically restores the original
behavior of getpwent.c as it is in -stable, and works around both
the lack of YPPROC_ORDER on NIS+ servers as well as the broken
YPPROC_MASTER on Services For UNIX servers.

318f2fb4bf Add a new mount flag MNT_BYFSID that can be used to unmount a file
system by specifying the file system ID instead of a path. Use this
by default in umount(8). This avoids the need to perform any vnode
operations to look up the mount point, so it makes it possible to
unmount a file system whose root vnode cannot be looked up (e.g.
due to a dead NFS server, or a file system that has become detached
from the hierarchy because an underlying file system was unmounted).
It also provides an unambiguous way to specify which file system is
to be unmunted.

Since the ability to unmount using a path name is retained only for
compatibility, that case now just uses a simple string comparison
of the supplied path against f_mntonname of each mounted file system.

fae3c3b7eb Rough implement of makecontext() needed to support libthr.
o  Up to 8 arguments are allowed. This is the number of arguments
   passed in registers. Subsequent registers are passed on the stack.
   Trying to deal with this is not easy in C and likely forces us to
   use assembly code. Let's avoid that for now. There's no indication
   that more than 8 arguments is a strong requirement (Linux also has
   an 8 argument limit).
o  We expect that the stack base is 16-byte aligned and the stack
   size is a multiple of 16-byte. We bomb out if this is not the case.
   We probably want to be less strict by enforcing it ourselves. For
   now it's better to not hide gross alignment bogons by silently
   correcting it.

22e4d31a81 Fix amd(8) clients, if a FreeBSD mountd(8) server is used.
Remove the special treatment of non-blocking mode in
the "look ahead function" xdrrec_eof(). It currently
assumes that the last read() in a row of several reads
does not have zero lenght. If this is the case, svc_vc_stat()
does return XPRT_MOREREQS, and the RPC-request aborts because
there is no data to read anymore.

To fix this, go back to the original version of the code
for non-blocking mode until NetBSD comes up with another
possible fix like this one in xdrrec_eof()

	if (rstrm->last_frag && rstrm->in_finger == rstrm->in_boundry) {
		return TRUE;
	}

Return always FALSE in set_input_fragment() for non-blocking
mode. Since this was not used in FreeBSD, I omitted it at the
first time. Now we use this function and we should always
return FALSE for it.

f2c49dd248 Revamp of the syscall path, exception and context handling. The
prime objectives are:
o  Implement a syscall path based on the epc inststruction (see
   sys/ia64/ia64/syscall.s).
o  Revisit the places were we need to save and restore registers
   and define those contexts in terms of the register sets (see
   sys/ia64/include/_regset.h).

Secundairy objectives:
o  Remove the requirement to use contigmalloc for kernel stacks.
o  Better handling of the high FP registers for SMP systems.
o  Switch to the new cpu_switch() and cpu_throw() semantics.
o  Add a good unwinder to reconstruct contexts for the rare
   cases we need to (see sys/contrib/ia64/libuwx)

Many files are affected by this change. Functionally it boils
down to:
o  The EPC syscall doesn't preserve registers it does not need
   to preserve and places the arguments differently on the stack.
   This affects libc and truss.
o  The address of the kernel page directory (kptdir) had to
   be unstaticized for use by the nested TLB fault handler.
   The name has been changed to ia64_kptdir to avoid conflicts.
   The renaming affects libkvm.
o  The trapframe only contains the special registers and the
   scratch registers. For syscalls using the EPC syscall path
   no scratch registers are saved. This affects all places where
   the trapframe is accessed. Most notably the unaligned access
   handler, the signal delivery code and the debugger.
o  Context switching only partly saves the special registers
   and the preserved registers. This affects cpu_switch() and
   triggered the move to the new semantics, which additionally
   affects cpu_throw().
o  The high FP registers are either in the PCB or on some
   CPU. context switching for them is done lazily. This affects
   trap().
o  The mcontext has room for all registers, but not all of them
   have to be defined in all cases. This mostly affects signal
   delivery code now. The *context syscalls are as of yet still
   unimplemented.

Many details went into the removal of the requirement to use
contigmalloc for kernel stacks. The details are mostly CPU
specific and limited to exception_save() and exception_restore().
The few places where we create, destroy or switch stacks were
mostly simplified by not having to construct physical addresses
and additionally saving the virtual addresses for later use.

Besides more efficient context saving and restoring, which of
course yields a noticable speedup, this also fixes the dreaded
SMP bootup problem as a side-effect. The details of which are
still not fully understood.

This change includes all the necessary backward compatibility
code to have it handle older userland binaries that use the
break instruction for syscalls. Support for break-based syscalls
has been pessimized in favor of a clean implementation. Due to
the overall better performance of the kernel, this will still
be notived as an improvement if it's noticed at all.

8d8a622e6b Update for AMD64 (repocopied from i386/net). We can depend on having
the bswap instruction (yay!).  Update for register parameter passing
instead of i386 style stack based param passing.

4dbb9c65d7 Update for AMD64-style syscalls. Repocopied from i386/SYS.h.
Note that the syscall instruction clobbers %rcx, which is inconvenient
because it is the fourth syscall argument, so we use %r10 (another scratch
register) for the 4th syscall arg instead (I picked %r10 to be the same as
NetBSD).  int 0x80 is still possible though, and it uses %rcx as usual.
Note that the syscall style syscall does *NOT* preserve all the registers,
unlike int 0x80.  We do not preserve the scratch registers except for
%rdi and %rsi.  int 0x80 does preserve everything but the return values.

e2527daf1a In compat mode, we `redispatch' the lookup. It is probably a good
idea to re-initialize `struct passwd', because e.g. pw_class might
get set by one module, but not by another.  Add another call to the
internal pwd_init function to accomplish this.
