First take at security model abstraction. - 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.

Full credit for the regression tests, making sure these changes didn't break anything, goes to Matt Fleming and Jaime Fournier. Happy birthday Randi! :)

# $NetBSD: std,v 1.7 2006/09/08 20:58:57 elad Exp $
add conf/std for MI standard options. currently empty.

#
# standard MI 'options'
#
# this file is for options which can't be off-by-default for some reasons.
# "it's commonly used" is NOT a good reason to enable options here.
enable VMSWAP by default.
2005-09-17 18:39:11 +04:00
# the following options are on-by-default to keep
# kernel config file compatibility.
options VMSWAP # Swap device/file support
- defflag bufq_fcfs and bufq_disksort. - make them on by default.
2005-09-26 18:14:26 +04:00
options BUFQ_FCFS # First-come First-serve strategy
options BUFQ_DISKSORT # Traditional min seek sort strategy
Add support for RFC 3542 Adv. Socket API for IPv6 (which obsoletes 2292). * RFC 3542 isn't binary compatible with RFC 2292. * RFC 2292 support is on by default but can be disabled. * update ping6, telnet and traceroute6 to the new API. From the KAME project (www.kame.net). Reviewed by core.
2006-05-05 04:03:21 +04:00
options RFC2292 # Previous version of Adv. Sockets API for IPv6
Make PTRACE and COREDUMP optional. Make the default (status quo) by putting them in conf/std.
2006-08-30 03:34:48 +04:00
options PTRACE # Include ptrace(2)
options COREDUMP # allow processes to coredump.
