93f0eafde3 linux_ioctl_cdrom: reduce stack usage
... by moving two ~2KB structures from stack to heap allocation.
I experienced stack overflow in linux emulation on i386 (8K stack)
when LINUX_DVD_READ_STRUCT ioctl was performed on atapicam cd
device and there was an error that resulted in additional quite
heavy stack use in cam layer.

ee1c1433e3 Add a function to the experimental nfs subsystem that tests to see
if a local file system supports NFSv4 ACLs. This allows the
NFSHASNFS4ACL() macro to be correctly implemented. The NFSv4 ACL
support should now work when the server exports a ZFS volume.

73d0971bf2 Add support for the arbitrary named jail parameters used by jail_set(2)
and jail_get(2).  Jail(8) can now create jails using a "name=value"
format instead of just specifying a limited set of fixed parameters; it
can also modify parameters of existing jails.  Jls(8) can display all
parameters of jails, or a specified set of parameters.  The available
parameters are gathered from the kernel, and not hard-coded into these
programs.

Small patches on killall(1) and jexec(8) to support jail names with
jail_get(2).

0304c73163 Add hierarchical jails. A jail may further virtualize its environment
by creating a child jail, which is visible to that jail and to any
parent jails.  Child jails may be restricted more than their parents,
but never less.  Jail names reflect this hierarchy, being MIB-style
dot-separated strings.

Every thread now points to a jail, the default being prison0, which
contains information about the physical system.  Prison0's root
directory is the same as rootvnode; its hostname is the same as the
global hostname, and its securelevel replaces the global securelevel.
Note that the variable "securelevel" has actually gone away, which
should not cause any problems for code that properly uses
securelevel_gt() and securelevel_ge().

Some jail-related permissions that were kept in global variables and
set via sysctls are now per-jail settings.  The sysctls still exist for
backward compatibility, used only by the now-deprecated jail(2) system
call.

efbad25934 Don't discard packets with 'Destination Unreachable' at the beginning
of ip_forward(), if the IPSEC is compiled in.  It is possible that there
is an SPD that this packets will go through, even if there is no matching
route.  If not, ICMP will be sent anyway, after ip_output().

This is somewhat similar in purpose to r191621, except that one was
for the packets sent from the host, while this one is for packets
being forwarded by the host.

a4ec37f59e Ensure that there are enough TX mbuf ring slots available before beginning
to dequeue a packet.

The tx path was trying to ensure that enough Xenbus TX ring slots existed but
it didn't check to see whether the mbuf TX ring slots were also available.
They get freed in xn_txeof() which occurs after transmission, rather than earlier
on in the process. (The same happens under Linux too.)

Due to whatever reason (CPU use, scheduling, memory constraints, whatever) the
mbuf TX ring may not have enough slots free and would allocate slot 0. This is
used as the freelist head pointer to represent "free" mbuf TX ring slots; setting
this to an actual mbuf value rather than an id crashes the code.

This commit introduces some basic code to track the TX mbuf ring use and then
(hopefully!) ensures that enough slots are free in said TX mbuf ring before it
enters the actual work loop.

A few notes:

* Similar logic needs to be introduced to check there are enough actual slots
  available in the xenbuf TX ring. There's some logic which is invoked earlier
  but it doesn't hard-check against the number of available ring slots.
  Its trivial to do; I'll do it in a subsequent commit.

* As I've now commented in the source, it is likely possible to deadlock the
  driver under certain conditions where the rings aren't receiving any changes
  (which I should enumerate) and thus Xen doesn't send any further software
  interrupts. I need to make sure that the timer(s) are running right and
  the queues are periodically kicked.

0e6993e4a7 Add in some INVARIANT checks in the TX mbuf descriptor "freelist" management code.
Slot 0 must always remain "free" and be a pointer to the first free entry in the
mbuf descriptor list. It is thus an error to have code allocate or push slot 0
back into the list.

00e8c94f25 Fix various cases with 3 or 4 parameters in test(1) to be POSIX compliant.
More precisely, this gives precedence to an interpretation not using the
'(', ')', '-a' and '-o' in their special meaning, if possible. For example,
it is now safe to write [ "$a" = "$b" ] and assume it compares the two
strings.

The man page already says that test(1) works this way, so does not need to
be changed.

Interpretation of input with more parameters tries a bit harder to find a
valid parse in some cases.

Add various additional test cases to TEST.sh.

c3e22f831f Fix the experimental nfs subsystem so that it builds with the
current NFSv4 ACLs, as defined in sys/acl.h. It still needs a
way to test a mount point for NFSv4 ACL support before it will
work. Until then, the NFSHASNFS4ACL() macro just always returns 0.

00a5db46de Add the ksyms(4) pseudo driver. The ksyms driver allows a process to
get a quick snapshot of the kernel's symbol table including the symbols
from any loaded modules (the symbols are all merged into one symbol
table).  Unlike like other implementations, this ksyms driver maps
memory in the process memory space to store the snapshot at the time
/dev/ksyms is opened.  It also checks to see if the process has already
a snapshot open and won't allow it to open /dev/ksyms it again until it
closes first.  This prevents kernel and process memory from being
exhausted.  Note that /dev/ksyms is used by the lockstat(1) command.
