Make fts_{alloc,safe_changed}() const correct

2021-01-08T16:06:30Z

Previously, this code was passing string constants to functions that did not declare their parameters as const. After this patch, the functions now declare that they do not modify these arguments, making it safe to pass string constants. Fixes -Wincompatible-pointer-types-discards-qualifiers.

sleep(3): don't bypass nanosleep(2) if seconds is zero

2021-01-07T15:24:52Z

sleep(3) does not call nanosleep(2) if seconds is zero. This is bad. As a simplified interface to nanosleep(2), sleep(3) should delegate all decisions about whether or not to yield the CPU to nanosleep(2). This patch removes the nanosleep(2) bypass from sleep(3). This means that this code: sleep(0); will block for up to 1 tick, just like the equivalent nanosleep(2) call. Neither FreeBSD nor NetBSD bypass nanosleep(2) in the zero case, so this commit brings our sleep(3) closer to theirs in behavior. As an added bonus, sleep(3) will now *always* appear in a ktrace(1) as a call to nanosleep(2). ok millert@

Add support for timeconting in userland.

2020-07-06T13:33:05Z

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@
