2019-06-28When system calls indicate an error they return -1, not some arbitraryTheo de Raadt
value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future.

2019-03-23Remove useless secure_path(3) calls.Todd C. Miller

It replaces the existing pwcache.c functions user_from_uid(3) and group_from_gid(3) with the pax equivalents. Adapted from NetBSD (mycroft) changes from our own pax's cache.c. OK guenther@
2018-08-21Use an mmap()'d buffer instead of a static buffer for the contentsTodd C. Miller
of the pointer returned by getpw{ent,nam,uid}(). We unmap the buffer each time to catch callers using a stale passwd struct pointer. As a special case, we do not unmap the buffer if the previous lookup was for the same name or uid. This special case may be removed in the future. OK deraadt@
2018-07-12Add hw.ncpuonline to count the number of online CPUs.cheloha
The introduction of hw.smt means that logical CPUs can be disabled after boot and prior to suspend/resume. If hw.smt=0 (the default), there needs to be a way to count the number of hardware threads available on the system at any given time. So, import HW_NCPUONLINE/hw.ncpuonline from NetBSD and document it. hw.ncpu becomes equal to the number of CPUs given to sched_init_cpu() during boot, while hw.ncpuonline is equal to the number of CPUs available to the scheduler in the cpuset "sched_all_cpus". Set_SC_NPROCESSORS_ONLN equal to this new sysctl and keep _SC_NPROCESSORS_CONF equal to hw.ncpu. This is preferable to adding a new sysctl to count the number of configured CPUs and keeping hw.ncpu equal to the number of online CPUs because such a change would break software in the ecosystem that relies on HW_NCPU/hw.ncpu to measure CPU usage and the like. Such software in base includes top(1), systat(1), and snmpd(8), and perhaps others. We don't need additional locking to count the cardinality of a cpuset in this case because the only interfaces that can modify said cardinality are sysctl(2) and ioctl(2), both of which are under the KERNEL_LOCK. Software using HW_NCPU/hw.ncpu to determine optimal parallism will need to be updated to use HW_NCPUONLINE/hw.ncpuonline. Until then, such software may perform suboptimally. However, most changes will be similar to the change included here for libcxx's std::thread:hardware_concurrency(): using HW_NCPUONLINE in lieu of HW_NCPU should be sufficient for determining optimal parallelism for most software if the change to _SC_NPROCESSORS_ONLN is insufficient. Prompted by deraadt. Discussed at length with kettenis, deraadt, and sthen. Lots of patch tweaks from kettenis. ok kettenis, "proceed" deraadt

2018-03-02Return monotonically increasing values.cheloha
The latest POSIX description of times(3) (and all others I can find) suggests that times(3) should return monotonically increasing values and that these values are only useful for real time interval measurement. All extant uses of times(3) confirm that this expectation is shared by application programmers. So, change gettimeofday(2) to clock_gettime(2)/CLOCK_MONOTONIC to ensure the return value increases monotonically, even if the system clock is changed by the superuser. Then update the manpage accordingly. While we're updating the manpage, move the information about the return values to a new RETURN VALUES section to bring times.3 up to speed with other library man pages. Manpage changes kicked around on tech@ with millert@ and jmc@. times.3 ok millert@ tb@ jmc@ times.c ok millert@ tb@
