* timecounting: use C99-style initialization for all timecounter structscheloha2021-02-232-7/+26
| | | | | | | | | | | | | | | | | | The timecounter struct is large and I think it may change in the future. Changing it later will be easier if we use C99-style initialization for all timecounter structs. It also makes reading the code a bit easier. For reasons I cannot explain, switching to C99-style initialization sometimes changes the hash of the resulting object file, even though the resulting struct should be the same. So there is a binary change here, but only sometimes. No behavior should change in either case. I can't compile-test this everywhere but I have been staring at the diff for days now and I'm relatively confident this will not break compilation. Fingers crossed. ok gnezdo@

* Refactor klist insertion and removalvisa2020-12-251-4/+4
| | | | | | | | | | | | Rename klist_{insert,remove}() to klist_{insert,remove}_locked(). These functions assume that the caller has locked the klist. The current state of locking remains intact because the kernel lock is still used with all klists. Add new functions klist_insert() and klist_remove() that lock the klist internally. This allows some code simplification. OK mpi@

* alpha, loongson, sh, sparc64: recompute tick, tick_nsec when hz(9) is resetcheloha2020-10-201-1/+3
| | | | | | | | | | | | | | Normally we set hz(9) at compile-time in sys/conf/param.c to the value of HZ. HZ is one of the fundamental compilation options(4). However, sometimes we need to reset hz(9) at runtime. Whenever we reset hz(9) we need to recompute tick and tick_nsec. Otherwise a variety of "time stuff" in the kernel will not work correctly. For example, most timeouts will expire "too slow" or "too fast". There are a bunch of other places we use tick and tick_nsec that will exhibit similar problems. Test-compiled by deraadt@.

| | | | | | | | This should be sufficient for identifying pivoted ROP. Doing so for other traps is at best opportunistic for finding a straight-running ROP chain, but the added (and rare) sleeping point has proven to be dangerous.

* Add support for timeconting in userland.pirofti2020-07-063-5/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | This diff exposes parts of clock_gettime(2) and gettimeofday(2) to userland via libc eliberating processes from the need for a context switch everytime they want to count the passage of time. If a timecounter clock can be exposed to userland than it needs to set its tc_user member to a non-zero value. Tested with one or multiple counters per architecture. The timing data is shared through a pointer found in the new ELF auxiliary vector AUX_openbsd_timekeep containing timehands information that is frequently updated by the kernel. Timing differences between the last kernel update and the current time are adjusted in userland by the tc_get_timecount() function inside the MD usertc.c file. This permits a much more responsive environment, quite visible in browsers, office programs and gaming (apparently one is are able to fly in Minecraft now). Tested by robert@, sthen@, naddy@, kmos@, phessler@, and many others! OK from at least kettenis@, cheloha@, naddy@, sthen@
