# sysctl net.link.ether.bdg_ipf=1
To enable. Just like ipfw(8) bridging, only input packets are filtered
in the bridge. Filtering works just like in the IP layer, ipf(8)
first, then ipfw(8). And just like in the IP layer, both are
independent, one need not be run to use the other. (Note: This will
not work in, but doesn't break, the bridge.ko module. The ipl.ko
module would need to be fixed before that is worth worrying about.)

- Bootstrap pvo entries are now allocated by stealing pages.
- Just return if we're pmap_enter'ing a mapping that's already there. Don't
remove it and re-enter it.
This is a set of userland shims in which GEOM can be run through simple
tests.
The simulation of kernel synchronization primitives is very primitive
and consequently some times tests will fail because of races.
Data/ contains a number of files in XML format which describe the
key sectors for a number of disk images
This is a very handy tool for people developing GEOM methods. The
"simdisk" method can be told to read from a "real disk" and afterwards
dump the accessed sectors in XML format for further use.
I hope future method writes will see the benefit of this test
collection and add to it when they write methods for GEOM.
You will need ports/textproc/expat for the XML parser.

modules split across several physical medias. Following is how it works:
The splitfs code, when asked to open "foo" looks for a file "foo.split"
which is a text file containing a list of filenames and media names, e.g.
foo.aa "Kernel floppy 1"
foo.ab "Kernel floppy 2"
foo.ac "Kernel and modules floppy"
For each file segment, the process is:
- try to open the file
- prompt "Insert the disk labelled <whatever> and press any key..."
- try to open the file
- return error if file could not be located
RE team is free to use this feature in the upcoming 5.0-DP1.

the release notes compare 5.0-CURRENT to 4.0-RELEASE, but in at least

the motivation for saving and restoring the map->hint in useracc() is gone.
(The same tests that motivated this change in revision 1.57 now show that
there is no performance loss from removing it.) This was really a hack and
some day we would have had to add new synchronization here on map->hint
to maintain it.
to copy the sigframe to the user's stack. Useracc() takes a non-trivial
amount of time. Eliminating it speeds up signal delivery by 15% or more.

the user mappings from the tlb due to the context numbers rolling over. The
store to the internal mmu register must be followed by a membar #Sync before
much else happens to "avoid data corruption", so we use special inlines which
both disable interrupts and ensure that the compiler will not insert extra
instructions between the two. Also, load the tte tag and check if the context
is nucleus context, rather than relying on the priviledged bit which doesn't
actually serve any purpose in our design, and check the lock bit too for
sanity.
locking flags when acquiring a vnode. The immediate purpose is
to allow polling lock requests (LK_NOWAIT) needed by soft updates
to avoid deadlock when enlisting other processes to help with
the background cleanup. For the future it will allow the use of
shared locks for read access to vnodes. This change touches a
lot of files as it affects most filesystems within the system.
It has been well tested on FFS, loopback, and CD-ROM filesystems.
only lightly on the others, so if you find a problem there, please
let me (mckusick@mckusick.com) know.
