the MROUTER is running, the system would panic as described in the PR.
The fix in the PR is a good start, however, the other state associated
with the multicast forwarding cache has to be freed in order to avoid
leaking memory and other possible panics.
More care and attention is needed in this area.

goes away. Without this change, it leaks in_multi (and often ether_multi
state) if many clonable interfaces are created and destroyed in quick
succession.
The concept of this fix is borrowed from KAME. Detailed information about
this behaviour, as well as test cases, are available in the PR.

ioctls passing integer arguments should use the _IOWINT() macro.
This fixes a lot of ioctl's not working on sparc64, most notable
being keyboard/syscons ioctls.
Full ABI compatibility is provided, with the bonus of fixing the
handling of old ioctls on sparc64.

timer interrupt servicing for disabled HTT cores in ULE case. Should be

ULE to do it.

this for 'initiator id'- this is a stopgap until a sparse map is
added.
Make compat defines for offset format (FreeBSD 5 or less).
Add no-asyncio flag. There's some breakage with ASYNC I/O that every
now and then drops us into an infinite loop. This also then does
a fallback to no-asyncio if the AIO option isn't loaded/compiled into
the kernel.
A number of other chanes to try and track some breakage.
- Change variable name to 'error', as this is what is mostly used for
functions that return an error.
- Add mutex(9) to the SEE ALSO section.
- Bump the date.
I don't really like the example code. I'd prefer symmetry where possible, eg.
mtx_lock(&example_lock);
error = example(NULL, EXAMPLE_ONE);
mtx_unlock(&example_lock);
if (error != 0)
return (error);
But I'll leave it as it is for now.

The key problem was that the aperture size detection using the MSAC bit
doesn't work -- the bit appears to be set even when it shouldn't be. Linux
takes a different approach, testing for a bit of the GMADR (PCIR_BAR(2)) being
set. However, as I don't think that's a safe way to test aperture size, we
just allocate the resource and check its size. This also pointed out that
agp_generic_attach hadn't been allocating our aperture resource, which may
have caused problems in some cases.
Also corrected is a minor copy-and-pasteo in an error case.

With the first part of my previous Summer of Code work, we get:
-made libalias modular:
-support for 'particular' protocols (like ftp/irc/etcetc) is no more
hardcoded inside libalias, but it's available through external
modules loadable at runtime
-modules are available both in kernel (/boot/kernel/alias_*.ko) and
user land (/lib/libalias_*)
-protocols/applications modularized are: cuseeme, ftp, irc, nbt, pptp,
skinny and smedia
-added logging support for kernel side
-cleanup
After a buildworld, do a 'mergemaster -i' to install the file libalias.conf
in /etc or manually copy it.
During startup (and after every HUP signal) user land applications running
the new libalias will try to read a file in /etc called libalias.conf:
that file contains the list of modules to load.
User land applications affected by this commit are ppp and natd:
if libalias.conf is present in /etc you won't notice any difference.
The only kernel land bit affected by this commit is ng_nat:
if you are using ng_nat, and it doesn't correctly handle
ftp/irc/etcetc sessions anymore, remember to kldload
the correspondent module (i.e. kldload alias_ftp).
General information and details about the inner working are available
in the libalias man page under the section 'MODULAR ARCHITECTURE
(AND ipfw(4) SUPPORT)'.
NOTA BENE: this commit affects _ONLY_ libalias, ipfw in-kernel nat
support will be part of the next libalias-related commit.
