has a significant code size savings over <sys/tree.h>.
Also change prop_number_t to store all number objects in an r-b tree,
only ever allocating one object for any given number (we can do this
because numbers are immutable). This results in significant run-time
memory savings.
functions to a separate rb_tree_ops structure. Make every int explicit
in being signed or unsigned. Use RBDEBUG to enable debug code. Move
rbt_count to RBSTATS. Use RBSMALL to not keep track of min/max.
with some tweaks (add a comment and macro):
Handle odd byte case correctly in (ETHER_MIN_LEN-ETHER_CRC_LEN) padding
so that bus_space_set_region_2() won't be called with count==0.
converted the platform to use the MIPS3 cp0 for the hardclock interrupt yet,
but that should be done as well. In the meantime, there are no functional
changes.
useful. The functions delay, cpu_initclocks, and setstatclcokrate have been
renamed to mips3_delay, mips3_initclocks, and mips3_setstatclockrate.
We provide weak aliases for the original names, so machdep code doesn't have
to provide wrapper routines. (Giving good performance.)
I've moved mips3_clockintr, mips3_initclocks, and mips3_setstatclockrate to
their own mips3_clockintr file, because some ports may not be able to use
these, and its senseless to carry that baggage.
- Add a few scopes to the kernel: system, network, and machdep.
- Add a few more actions/sub-actions (requests), and start using them as
opposed to the KAUTH_GENERIC_ISSUSER place-holders.
- Introduce a basic set of listeners that implement our "traditional"
security model, called "bsd44". This is the default (and only) model we
have at the moment.
- Update all relevant documentation.
- Add some code and docs to help folks who want to actually use this stuff:
* There's a sample overlay model, sitting on-top of "bsd44", for
fast experimenting with tweaking just a subset of an existing model.
This is pretty cool because it's *really* straightforward to do stuff
you had to use ugly hacks for until now...
* And of course, documentation describing how to do the above for quick
reference, including code samples.
All of these changes were tested for regressions using a Python-based
testsuite that will be (I hope) available soon via pkgsrc. Information
about the tests, and how to write new ones, can be found on:
http://kauth.linbsd.org/kauthwiki
NOTE FOR DEVELOPERS: *PLEASE* don't add any code that does any of the
following:
- Uses a KAUTH_GENERIC_ISSUSER kauth(9) request,
- Checks 'securelevel' directly,
- Checks a uid/gid directly.
(or if you feel you have to, contact me first)
This is still work in progress; It's far from being done, but now it'll
be a lot easier.

Many thanks to YAMAMOTO Takashi, Matt Thomas, and Christos Zoulas for help
stablizing kauth(9).
Full credit for the regression tests, making sure these changes didn't break
anything, goes to Matt Fleming and Jaime Fournier.
Happy birthday Randi! :)
* Stop fhandle memory leaks and use the correct fhandle dealloc routine
(thanks to Elad for these fixes)
* Remove include of kmem.h, it is not required.
on port-ews4800mips.
XXX: ews4800mips can't use mips/mips/mips3_clock.c for now because
it isn't configured to use internal clock interrupt for CPU INT 5,
i.e. mips3_clockintr() is not needed and its own cpu_initclocks(9)
is required.
