fetch(1) accepts a new argument -i <file> that if specified will cause
the file to be downloaded only if it is more recent than the mtime of
<file>.
libfetch(3) accepts the mtime in the url structure and a flag to
indicate when this behavior is desired.

1. separating L2 tables (ARP, NDP) from the L3 routing tables
2. removing as much locking dependencies among these layers as
possible to allow for some parallelism in the search operations
3. simplify the logic in the routing code,
The most notable end result is the obsolescent of the route
cloning (RTF_CLONING) concept, which translated into code reduction
in both IPv4 ARP and IPv6 NDP related modules, and size reduction in
struct rtentry{}. The change in design obsoletes the semantics of
RTF_CLONING, RTF_WASCLONE and RTF_LLINFO routing flags. The userland
applications such as "arp" and "ndp" have been modified to reflect
those changes. The output from "netstat -r" shows only the routing
entries.
Quite a few developers have contributed to this project in the
past: Glebius Smirnoff, Luigi Rizzo, Alessandro Cerri, and
Andre Oppermann. And most recently:
- Kip Macy revised the locking code completely, thus completing
the last piece of the puzzle, Kip has also been conducting
active functional testing
- Sam Leffler has helped me improving/refactoring the code, and
provided valuable reviews
- Julian Elischer setup the perforce tree for me and has helped
me maintaining that branch before the svn conversion

This change was erronously ommitted from the r185690, and attempt
to simply add the prototype to string.h has revealed that several
contributed programs defined local prototypes for strndup(), controlled
by autoconfed config.h. So, manually change #undef HAVE_STRNDUP to
#define HAVE_STRNDUP 1. Next import of the corresponding program would
regenerate config.h, overriding the changes in this commit.
No objections from: kan
in order to get the symbol binding state "just so". This is to allow
locking to be activated and not run into recursion problems later.
However, one of the magic bits involves an explicit call to _umtx_op()
to force symbol resolution. It does a wakeup operation on a fake,
uninitialized (ie: random contents) umtx. Since libthr isn't active, this
is harmless. Nothing can match the random wakeup.
However, valgrind finds this and is not amused. Normally I'd just
write a suppression record for it, but the idea of passing random
args to syscalls (on purpose) just doesn't feel right.

* support for bzip2 file with multiple concatenated bzip2 streams
* support for bzip2 file with junk after bzip2 stream
* 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.)
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.
