Another 40% is fixed by generating _pic.a variants of various libraries. 3. Some of the NO_PIE use is a bit absurd as it is disabling PIE (and ASLR) where it never would work anyhow, such as csu or loader. This suggests there may be better ways of adding support to the tree. Many of these cases can be fixed such that -fPIE will work but there is really no reason to have it in those cases. 4. Some of the uses are working around hacks done to some Makefiles that are really building libraries but have been using bsd.prog.mk because the code is cleaner. Had they been using bsd.lib.mk then NO_PIE would not have been needed. We likely do want to enable PIE by default (opt-out) for non-tree consumers (such as ports). For in-tree though we probably want to only enable PIE (opt-in) for common attack targets such as remote service daemons and setuid utilities. This is also a great performance compromise since ASLR is expected to reduce performance. As such it does not make sense to enable it in all utilities such as ls(1) that have little benefit to having it enabled. Reported by: kib

Once ASLR support is ready and stable it should changed to opt-out and be enabled by default along with ASLR. Each application Makefile uses opt-out to ensure that ASLR will be enabled by default in new directories when the system is compiled with PIE/ASLR. [2] Mark known build failures as NO_PIE for now.

This change also improves scheduling in the default mode by running as close to the beginning of the minnute as possible by replacing sleep(3) with nanosleep(2). Previously, the tasks would run anywhere within the first second of the minute and that offset drifted back and forth each time cron(8) was engaged. MFC after: 1 month

ENOTIME to implement crontab(5) format extensions to allow more flexible scheduling. In order to address some concerns expressed by Terry Lambert while discussing the topic few years ago, about per-second cron possibly causing some bad effects on /etc/crontab by stat()ing it every second instead of every minute now (i.e. atime update), only check that database needs to be reloaded on every 60-th loop run. This should be close enough to the current behaviour. Add "@every_minute" shortcut while I am here. MFC after: 1 month

According to POSIX, gettimeofday() has the following prototype: int gettimeofday(struct timeval *restrict tp, void *restrict tzp); Also, POSIX states that gettimeofday() shall return 0 (as long as tzp is not used). Remove dead error handling code. Also use NULL for a nul-pointer instead of integer 0. While there, change all pieces of code that only use tv_sec to use time(3), as this provides less overhead.
