- Remove hardcoded uid, gid, mode from struct pfs_node; make pfs_getattr()
smart enough to get it right most of the time, and allow for callbacks
to handle the remaining cases. Rework the definition macros to match.
- Add lots of (conditional) debugging output.
- Fix a long-standing bug inherited from procfs: don't pretend to be a
read-only file system. Instead, return EOPNOTSUPP for operations we
truly can't support and allow others to fail silently. In particular,
pfs_lookup() now treats CREATE as LOOKUP. This may need more work.
- In pfs_lookup(), if the parent node is process-dependent, check that
the process in question still exists.
- Implement pfs_open() - its only current function is to check that the
process opening the file can see the process it belongs to.
- Finish adding support for writeable nodes.
- Bump module version number.
- Introduce lots of new bugs.
next to equivalent m_len adjustments. Move the nfsm_subs.h macros
into groups depending on which phase they are used in, since that
affects the error recovery requirements. Collect some of the common error
checking into a single macro as preparation for unwinding some more.
Have nfs_rephead return a value instead of secretly modifying args.
Remove some unused function arguments that were being passed around.
Clarify nfsm_reply()'s error handling (I hope).

in the FreeBSD kernel. Therefore, map the syscall directly to

While here, redefine the second entry for setpgid() so that we
don't need a stub. This is achieved by giving the second instance
the type NODEF.

have its entry in the syscall table added. Nothing else is
done. This differs from type NOPROTO in that NOPROTO adds a
definition to syscall.h besides adding a sysent. A syscall can
now have multiple entries without conflict. Note that the
argssize is fixed and depends on the syscall name.

ethernet controllers. This adds support for the 3Com 3c996-T, the
SysKonnect SK-9D21 and SK-9D41, and the built-in gigE NICs on
Dell PowerEdge 2550 servers. The latter configuration hauls ass:
preliminary measurements show TCP speeds of over 900Mbps using
only normal size frames.
TCP/IP checksum offload, jumbo frames and VLAN tag insertion/stripping
are supported, as well as interrupt moderation.
Still need to fix autonegotiation support for 1000baseSX NICs, but
beyond that, driver is pretty solid.
+ implement "limit" rules, which permit to limit the number of sessions
between certain host pairs (according to masks). These are a special
type of stateful rules, which might be of interest in some cases.
See the ipfw manpage for details.
+ merge the list pointers and ipfw rule descriptors in the kernel, so
the code is smaller, faster and more readable. This patch basically
consists in replacing "foo->rule->bar" with "rule->bar" all over
the place.
I have been willing to do this for ages!

little nit that caused it to be defined as -(sizeof (struct thread) + 1)
instead of -2.
the current interrupt thread routines will guarantee the condition this is
checking for at a higher level but inthand_add() and inthand_remove() as
they currently exist don't satisfy this condition. (Which does need to be
fixed but which will take a bit more work.) This fixes shared interrupts.
sio_lock has been initialized. This prevents the low level console
output (kernel printf) from clobbering the sio settings if the system
happens to be in the middle of comstart().

There is an equivalent structure, struct ipoption in ip_var.h
which is actually used in various parts of the kernel, and also referenced
in Stevens.

PRISON_ROOT to the suser_xxx() check. Since securelevels may now
be raised in specific jails, use of system flags can still be
restricted in jail(), but in a more configurable way.
o Users of jail() expecting system flags (such as schg) to restrict
jail()'s should be sure to set the securelevel appropriately in
jail()'s.
o This fixes activities involving automated system flag removal in
jail(), including installkernel and friends.

securelevel_gt(), determine first if a local securelevel exists --
if so, perform the check based on imax(local, global). Otherwise,
simply use the global value.
o Note: even though local securelevels might lag below the global one,
if the global value is updated to higher than local values, maximum
will still be used, making the global dominant even if there is local
lag.

one is present in the current jail, otherwise, to return the global
securelevel.
o If the securelevel is being updated, require that it be greater than
the maximum of local and global, if a local securelevel exists,
otherwise, just maximum of the global. If there is a local
securelevel, update the local one instead of the global one.
o Note: this does allow local securelevels to lag behind the global one
as long as the local one is not updated following a global increase.
