Remove uarea swap-out functionality: - Addresses the issue described in PR/38828. - Some simplification in threading and sleepq subsystems. - Eliminates pmap_collect() and, as a side note, allows pmap optimisations. - Eliminates XS_CTL_DATA_ONSTACK in scsipi code. - Avoids few scans on LWP list and thus potentially long holds of proc_lock. - Cuts ~1.5k lines of code. Reduces amd64 kernel size by ~4k. - Removes __SWAP_BROKEN cases. Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on acorn26 (thanks to <bjh21>).

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.`
- Conditionalise POSIX aio and mqueue, but include them by default. - Add a COMPAT_NETBSD attribute. Emit if any compat options are used. 2008-11-15 02:28:30 +03:00			`options AIO # POSIX asynchronous I/O`
			`options MQUEUE # POSIX message queues`
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! :) 2006-09-09 00:58:56 +04:00

merge yamt-idlelwp branch. asked by core@. some ports still needs work. from doc/BRANCHES: idle lwp, and some changes depending on it. 1. separate context switching and thread scheduling. (cf. gmcgarry_ctxsw) 2. implement idle lwp. 3. clean up related MD/MI interfaces. 4. make scheduler(s) modular. 2007-05-17 18:51:11 +04:00

Add cpuctl(8). For now this is not much more than a toy for debugging and benchmarking that allows taking CPUs online/offline. 2007-08-04 15:02:56 +04:00
