* kernel: use gettime(9)/getuptime(9) in lieu of time_second(9)/time_uptime(9)cheloha2020-06-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | time_second(9) and time_uptime(9) are widely used in the kernel to quickly get the system UTC or system uptime as a time_t. However, time_t is 64-bit everywhere, so it is not generally safe to use them on 32-bit platforms: you have a split-read problem if your hardware cannot perform atomic 64-bit reads. This patch replaces time_second(9) with gettime(9), a safer successor interface, throughout the kernel. Similarly, time_uptime(9) is replaced with getuptime(9). There is a performance cost on 32-bit platforms in exchange for eliminating the split-read problem: instead of two register reads you now have a lockless read loop to pull the values from the timehands. This is really not *too* bad in the grand scheme of things, but compared to what we were doing before it is several times slower. There is no performance cost on 64-bit (__LP64__) platforms. With input from visa@, dlg@, and tedu@. Several bugs squashed by visa@. ok kettenis@

| | | | | | | | ESXi doesn't carry the guest info over when a guest gets moved to a different host, and this appears to be the only hint the guest gets that this has happened. ok dlg@

| | | | | | | | | | | mechanism is used to configure VMs in the VMware vSphere world: instead of using individual key-value guestinfo.* properties, it uses the guestinfo.ovfEnv value to pass an enterprise-compliant XML file that includes key-value properties. This file can be rather large, especially with comments, but 4k ought to be enough for anybody. Also change a stack buffer to malloc'ed memory in the ioctl path. OK mikeb@
* Add a key-value interface to pvbus(4) that allows to get or set valuesreyk2016-01-271-2/+57
| | | | | | | | | | | | | | in the underlying information store of the host from the OpenBSD-VM's userspace. OpenBSD did not provide access to these stores before, mostly because we did not want to add a custom tool and interface for each hypervisor. The pvbus(4) interface provides backends for xen(4)'s XenStore and vmt(4)'s VMware Tools "guestinfo". These information stores are fairly different, XenStore is a "filesystem" while vmt is a RPC, and the key-value abstraction limits them a bit but provides the most wanted functionality. Discussed with many OK mikeb@
