Add a simple netipx TODO list to the end of README, since there are a
number of problems with netipx that I have not yet resolved, and I
don't want them lost track of.
In spx_output(), use M_DONTWAIT instead of M_TRYWAIT, as we hold the
ipxpcb mutex. Contrary to the comment, even in 4.x this was unsafe,
as parallel use of the socket by another process would result in pcb
corruption if the mbuf allocation slept.
In various SPX protocol entry points from the socket layer, check
IPXP_DROPPED before continuing, and return EINVAL or ECONNRESET if
it is flagged. It's unclear why each situation should be one or
the other, but it is copied from netinet which has the same bugs.
Add a new ipxpcb flag, IPXP_SPX, which is set on ipxpcb's to mark them
as belonging to SPX. This replaces the implicit assumption that the cb
pointer for non-SPX pcb's will be NULL. This isn't required in TCP/IP
as different pcb lists are maintained for different IP protocols; IPX
stores all pcbs on the same global ipxpcb_list.

from HEAD to RELENG_6:
Rework IPX/SPX socket and pcb reference model:
- Introduce invariant that all IPX/SPX sockets will have valid so_pcb
pointers to ipxpcb structures, and that for SPX, the control block
pointer will always be valid. Don't attempt to free the socket or
pcb at various odd points, such as disconnect.
- Add a new ipxpcb flag, IPXP_DROPPED, which will be set in place of
freeing PCB's so that this invariant can be maintained. This flag
is now checked instead of a NULL check in various socket protocol
calls.
- Introduce many assertions that this invariant holds.
- Various pieces of code, such as the SPX timer code, no longer needs
to jump through hoops in case it frees a PCB while running.
- Break out ipx_pcbfree() from ipx_pcbdetach(). Likewise
spx_pcbdetach().
- Comment on some SMP-related limitations to the SPX code.
- Update copyrights.
Restructure spx_attach() to properly free memory in the event that one
of its allocations fails. Allocate the ipxp last so as to avoid having
to free it if another allocation goes wrong.
Normalize retrieval of ipxp and cb from socket in spx_sp_attach(), and
add assertions.
In spx_ctloutput(), acquire the ipxp lock around read operations,
especially reads of spx header structures, which will now be cached
in the stack until they can be copied out after releasing the lock.
Panic if a bad socket option direction is passed in by the caller.
Clean up and style(9) SPX code prior to significant functional changes
being committed:
- Wrap comments more evenly on right border.
- Clean up braces.
Also, along similar lines:
- Assert some pointers are non-NULL before dereferencing them.
- Remove one assertion that looks, on face value, poor.
Admit to ourselves that we don't actually implement pr_ctlinput() for
IPX or SPX, as the code in the implementing functions is essentially
a no-op. Replace with a comment indicating we don't implement these
currently.
In spx_attach() and spx_detach(), there is no need to check whether the
ipxpcb is NULL or not: in attach it will be, and on detach it won't be.
If for any reason these invariants don't hold true, panicking is a good
idea.

Comment that raw output filter code for IPX should run in a netisr so as
to avoid recursing the socket code, as this input path can run in the
call stack of an output path.
Move spx_savesi from being a global variable to an automatically allocated
variable on the spx_input() stack. It's not very large, and this will
avoid parallelism issues when spx_input() runs in more than one thread at
a time.
sysctl_ctx_init.9 from HEAD to RELENG_6:
Add a basic man page for the sysctl(9) macro interfaces. Previously man
pages existed only for the dynamic sysctl interfaces. There's probably
more complete and accurate content, better advice, etc, that could be
added here.
Per scottl's suggest, add a small piece of moralizing text regarding the
fact that sysctl names quickly get embedded in system configuration files,
libraries, third party applications, and even books, so renaming and
removing names after they've been published is a tricky issue.

Adjust minimum iod threads from 4 to 0 -- since we compile the NFS
client into the kernel by default, and many users won't use NFS,
don't start an extra 4 kernel threads that are unused. Once NFS
becomes active, it will start nfsiod's as it needs them.
We might consider mandating a minimum iod's equal to the number of
active NFS mounts (truncated to some value), which would force some
to remain available without having to create a new one if the file
system is mostly inactive.

- s,tramoline,trampoline, in a comment.
- Use FBSDID in trap.c
- Make the global trap_sig[] static as it's not used outside of trap.c.
- Sync cpu_thread_siginfo() and sendsig() with the other archs; for fast
data access MMU miss and data access protection traps set ksi_addr to
the SFAR reg which contains the faulting address and otherwise to the
TPC reg. Generally the TCP reg contains the address of the instruction
that caused the exception, except for fast instruction access traps
(and some others; more refinement may be needed here) it also contains
the faulting address.
Previously, sendsig() always set si_addr to the SFAR reg which is wrong
for most traps and cpu_thread_siginfo() didn't set it at all.
- In sendsig() add support for FreeBSD old-style signals.
- Set a two read-only variables (${prefix} and ${etcdir}). This is
especially useful when using /etc/rc.d scripts with third-party
software installed from ports.
- Fix rc.d/sshd to work with openssh from ports using ${etcdir}

Make this example more real world usable: When the manpage first appeared
is not interesting, when the driver appeared is. Most people who use this
example leave the manpage appearance date in and the driver date out.
