* support for gzip file with junk after gzip stream
* "fuzz" tester randomly modifies a bunch of input files in order to try
to crash libarchive (this found an amusing hang in the ISO9660 code
when trying to read images that advertised a zero blocksize).
This test is implemented, but commented out for now:
* support for gzip file with multiple concatenated gzip streams
This is an attempt to eliminate a lot of redundant
code from the read ("decompression") filters by
changing them to juggle arbitrary-sized blocks
and consolidate reblocking code at a single point
in archive_read.c.
Along the way, I've changed the internal read/consume
API used by the format handlers to a slightly
different style originally suggested by des@. It
does seem to simplify a lot of common cases.
The most dramatic change is, of course, to
archive_read_support_compression_none(), which
has just evaporated into a no-op as the blocking
code this used to hold has all been moved up
a level.
There's at least one more big round of refactoring
yet to come before the individual filters are as
straightforward as I think they should be...
* Wrap long declarations to fit 80 chars
* #undef macros that shouldn't be exported
* Organize the version-dependent conditionals a
bit more consistently
Speculative:
* libarchive 3.0 will (eventually) use int64_t
instead of off_t. This is an attempt to avoid
some the headaches caused by Linux LFS. (I'll
still have to do ugly things for the struct stat
references in archive_entry.h, of course.)

memory barriers on i386. It works as a serialization instruction on
all IA32 CPUs.
Alternative solution of using {s,l,}fence requires run-time checking
of the presense of the corresponding SSE or SSE2 extensions, and
possible boot-time patching of the kernel text.
Suggested by: many
parent threads sleep on the parent' struct proc until corresponding
child releases the vmspace. Each sleep is interlocked with proc mutex of
the child, that triggers assertion in the sleepq_add(). The assertion
requires that at any time, all simultaneous sleepers for the channel use
the same interlock.
Silent the assertion by using conditional variable allocated in the
child. Broadcast the variable event on exec() and exit().
Since struct proc * sleep wait channel is overloaded for several
unrelated events, I was unable to remove wakeups from the places where
cv_broadcast() is added, except exec().

revised/modified by me) to store dhcp options into kenv variables,
so the information is available to the boot loader and can be used
to customize the boot process.
The change is totally unintrusive, essentially made of a single
function to be called while parsing a dhcp response, and a couple
of tables to classify options. The values extracted from dhcp
options are stored in the kenv environment in one of these forms:
+ options whose name and type is known are saved as
dhcp.name = value (string, or number/ip addresses lists)
+ unknown options are assumed to be strings and saved as
dhcp.option-NNN = "value"
+ options listed as '__INDIR' and sent on the wire as e.g.
option unknown-252 "some.name=the actual value"
are saved as
some.name = "the actual value"
+ options listed as '__ILIST' and sent on the wire as e.g.
option unknown-249 "a.b=foo bar; c.d= 123; e.f=done"
are saved as multiple values
a.b="foo bar"
c.d="123"
e.f="done"
As you can see there is quite a bit of flexibility on what can
be passed to the loader or the kernel.
For the time being the vendor-specific table is mostly disabled,
because there is no standard set of options for FreeBSD, and I don't
know all the pxe-specific vendor options.
Also, applications using libstand may live in memory-constrained
environments, so it makes sense to keep these tables as small as
possible, especially considering that one can generate arbitrary
name=value pairs using site-specific options of type __INDIR or
__ILIST (there are 4 __ILIST and 5 __INDIR in the table, numbered
246..249 and 250..254).
Actually, considering that probably 75% of the standard dhcp options
are totally useless, it might make sense to remove them as well.

move that module to the head of the associated linker file's list of modules.
The end result is that once all the modules are loaded, they are sorted in
the reverse of their load order. This causes the kernel linker to invoke
the MOD_QUIESCE and MOD_UNLOAD events in the reverse of the order that
MOD_LOAD was invoked. This means that the ordering of MOD_LOAD events that
is set by the SI_* paramters to DECLARE_MODULE() are now honored in the same
order they would be for SYSUNINIT() for the MOD_QUIESCE and MOD_UNLOAD
events.

unloading any modules. As a result, if any module veto's an unload
request via MOD_QUIESCE, the entire set of modules for that linker
file will remain loaded and active now rather than leaving the kld
in a weird state where some modules are loaded and some are unloaded.
- This also moves the logic for handling the "forced" unload flag out of
kern_module.c and into kern_linker.c which is a bit cleaner.
- Add a module_name() routine that returns the name of a module and use that
instead of printing pointer values in debug messages when a module fails
MOD_QUIESCE or MOD_UNLOAD.
