| | | | | | | | | | | | | | | | | | | r256543: Add fasttrap for PowerPC. This is the last piece of the DTrace/ppc puzzle. It's incomplete, it doesn't contain full instruction emulation, but it should be sufficient for most cases. r259245,r259421: (FBT) FBT now does work fully on PowerPC. Save r3 before using it for the trap check, else we end up saving the new r3, containing the trap instruction encoding (0x7c810808), and restoring it back with the frame on return. This caused it to panic on my ppc32 machine. r259668,r259674: Fix a typo in the FBT code.

Use a GCC_MS_EXTENSIONS variable, defined in kern.pre.mk, which can be used to easily supply the flag (or not), depending on the compiler type. MFC r260322: In addition to r260102, also define GCC_MS_EXTENSIONS in bsd.sys.mk, since kernel module builds do not use kern.pre.mk.

| | | | | | | | | | | | | | For sys/dev/drm2/radeon, only use -fms-extensions with gcc. This flag is only to stop gcc complaining about anonymous unions, which clang does not do. For clang 3.4 however, -fms-extensions enables the Microsoft __wchar_t type, which clashes with our own types.h. MFC r260102: Similar to r260020, only use -fms-extensions with gcc, for all other modules which require this flag to compile.

Main points include: * Userland seeding is no longer used. This auto-seeds at boot time on PC/Desktop setups; this may need some tweeking and intelligence from those folks setting up embedded boxes, but the work is believed to be minimal. * An entropy cache is written to /entropy (even during installation) and the kernel uses this at next boot. * An entropy file written to /boot/entropy can be loaded by loader(8) * Hardware sources such as rdrand are fed into Yarrow, and are no longer available raw. ------------------------------------------------------------------------ r256240 | des | 2013-10-09 21:14:16 +0100 (Wed, 09 Oct 2013) | 4 lines Add a RANDOM_RWFILE option and hide the entropy cache code behind it.

Add a SYSINIT that forces a reseed during proc0 setup, which happens fairly late in the boot process. Add a RANDOM_DEBUG option which enables some debugging printf()s. Add a new RANDOM_ATTACH entropy source which harvests entropy from the get_cyclecount() delta across each call to a device attach method. ------------------------------------------------------------------------ r256135 | markm | 2013-10-08 07:54:52 +0100 (Tue, 08 Oct 2013) | 8 lines Debugging. My attempt at EVENTHANDLER(multiuser) was a failure; use EVENTHANDLER(mountroot) instead. This means we can't count on /var being present, so something will need to be done about harvesting /var/db/entropy/... . Some policy now needs to be sorted out, and a pre-sync cache needs to be written, but apart from that we are now ready to go. Over to review. ------------------------------------------------------------------------ r256094 | markm | 2013-10-06 23:45:02 +0100 (Sun, 06 Oct 2013) | 8 lines Snapshot. Looking pretty good; this mostly works now. New code includes: * Read cached entropy at startup, both from files and from loader(8) preloaded entropy. Failures are soft, but announced. Untested. * Use EVENTHANDLER to do above just before we go multiuser. Untested. ------------------------------------------------------------------------ r256088 | markm | 2013-10-06 14:01:42 +0100 (Sun, 06 Oct 2013) | 2 lines Fix up the man page for random(4).

This now works, except that the "live" sources haven't been tested. With all sources turned on, this unlocks itself in a couple of seconds! That is no my box, and there is no guarantee that this will be the case everywhere. * Cut debug prints. * Use the same locks/mutexes all the way through. * Be a tad more conservative about entropy estimates. ------------------------------------------------------------------------ r256084 | markm | 2013-10-06 13:35:29 +0100 (Sun, 06 Oct 2013) | 5 lines Don't use the "real" assembler mnemonics; older compilers may not understand them (like when building CURRENT on 9.x). # Submitted by: Konstantin Belousov <kostikbel@gmail.com> ------------------------------------------------------------------------ r256081 | markm | 2013-10-06 10:55:28 +0100 (Sun, 06 Oct 2013) | 12 lines SNAPSHOT. Simplify the malloc pools; We only need one for this device. Simplify the harvest queue. Marginally improve the entropy pool hashing, making it a bit faster in the process. Connect up the hardware "live" source harvesting. This is simplistic for now, and will need to be made rate-adaptive. All of the above passes a compile test but needs to be debugged. ------------------------------------------------------------------------ r256042 | markm | 2013-10-04 07:55:06 +0100 (Fri, 04 Oct 2013) | 25 lines Snapshot. This passes the build test, but has not yet been finished or debugged. Contains: * Refactor the hardware RNG CPU instruction sources to feed into the software mixer. This is unfinished. The actual harvesting needs to be sorted out. Modified by me (see below). * Remove 'frac' parameter from random_harvest(). This was never used and adds extra code for no good reason. * Remove device write entropy harvesting. This provided a weak attack vector, was not very good at bootstrapping the device. To follow will be a replacement explicit reseed knob. * Separate out all the RANDOM_PURE sources into separate harvest entities. This adds some secuity in the case where more than one is present. * Review all the code and fix anything obviously messy or inconsistent. Address som review concerns while I'm here, like rename the pseudo-rng to 'dummy'. # Submitted by: Arthur Mesh <arthurmesh@gmail.com> (the first item) ------------------------------------------------------------------------ r255319 | markm | 2013-09-06 18:51:52 +0100 (Fri, 06 Sep 2013) | 4 lines Yarrow wants entropy estimations to be conservative; the usual idea is that if you are certain you have N bits of entropy, you declare N/2. ------------------------------------------------------------------------ r255075 | markm | 2013-08-30 18:47:53 +0100 (Fri, 30 Aug 2013) | 4 lines Remove short-lived idea; thread to harvest (eg) RDRAND enropy into the usual harvest queues.

For the rest use a neutral name. 2) Tidy up headers; put private stuff in private places. More could be done here. 3) Streamline the hashing/encryption; no need for a 256-bit counter; 128 bits will last for long enough. There are bits of debug code lying around; these will be removed at a later stage. ------------------------------------------------------------------------ r254784 | markm | 2013-08-24 14:54:56 +0100 (Sat, 24 Aug 2013) | 39 lines 1) example (partially humorous random_adaptor, that I call "EXAMPLE") * It's not meant to be used in a real system, it's there to show how the basics of how to create interfaces for random_adaptors. Perhaps it should belong in a manual page 2) Move probe.c's functionality in to random_adaptors.c * rename random_ident_hardware() to random_adaptor_choose() 3) Introduce a new way to choose (or select) random_adaptors via tunable "rngs_want" It's a list of comma separated names of adaptors, ordered by preferences. I.e.: rngs_want="yarrow,rdrand" Such setting would cause yarrow to be preferred to rdrand. If neither of them are available (or registered), then system will default to something reasonable (currently yarrow). If yarrow is not present, then we fall back to the adaptor that's first on the list of registered adaptors. 4) Introduce a way where RNGs can play a role of entropy source. This is mostly useful for HW rngs. The way I envision this is that every HW RNG will use this functionality by default. Functionality to disable this is also present.
