* Enable iterating all sysctls, even ones with CTLFLAG_SKIPRyan Moeller2020-10-051-14/+21
| | | | | | | | | | | | | | | | | | | | | | | | | Add an "nextnoskip" sysctl that allows for listing of sysctls intended to be normally skipped for cost reasons. This makes it so the names/descriptions of those sysctls can be discovered with sysctl -aN/sysctl -ad/sysctl -at. It also makes it so children are visited when a node flagged with CTLFLAG_SKIP is explicitly requested. The intended use case is to mark the root "kstat" node with CTLFLAG_SKIP so that the extensive and expensive stats are skipped by default but may still be easily obtained without having to know them all (which may not even be possible) and request each one-by-one.

* Add sysctl(8) formatting for hw.pagesizes.Mark Johnston2020-09-021-0/+25
| | | | | | | | | | | | | | | | | | - Change the type of hw.pagesizes to OPAQUE, since it returns an array. - Modify the handler to only truncate the returned length if the caller supplied an output buffer. This allows use of the trick of passing a NULL output buffer to fetch the output size, while preserving compatibility if MAXPAGESIZES is increased. - Add a "S,pagesize" formatter to sysctl(8).

* evdev: export event device properties through sysctl interfaceVladimir Kondratyev2019-02-241-0/+19
| | | | | | | | | | | | | | | | | | | A big security advantage of Wayland is not allowing applications to read input devices all the time. Having /dev/input/* accessible to the user account subverts this advantage. libudev-devd was opening the evdev devices to detect their types (mouse, keyboard, touchpad, etc). This don't work if /dev/input/* is inaccessible. With the kernel exposing this information as sysctls (kern.evdev.input.*), we can work w/o /dev/input/* access, preserving the Wayland security model.

* Permit sysctl(8) to set an array of numeric values for a single node.John Baldwin2018-03-092-93/+135
| | | | | | | | | | | | | | | | | | | | Most sysctl nodes only return a single value, but some nodes return an array of values (e.g. kern.cp_time). sysctl(8) understand how to display the values of a node that returns multiple values (it prints out each numeric value separated by spaces). However, until now sysctl(8) has only been able to set sysctl nodes to a single value. This change allows sysctl to accept a new value for a numeric sysctl node that contains multiple values separated by either spaces or commas. sysctl(8) parses this list into an array of values and passes the array as the "new" value to sysctl(2).

* General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-1/+3
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326025

* Don't request CTLTYPE_OPAQUE if we can't print them.Andrew Gallatin2017-07-311-18/+26
| | | | | | | | | | | | | | | | | | | The intent is to skip expensive opaque sysctls like tcp_pcblist unless they are explicitly requested. Sysctl nodes like this don't show up in sysctl -a, but they do generate output that winds up being dropped, unless the user specifically requested binary/hex output or opaques. This reduces the runtime of sysctl in many circumstances on a loaded system. It also reduces the likelihood that simply gathering diagnostics on a sick machine (stuck lock, etc) via sysctl -a might push it over the edge into a total lockup.
