in the wrong direction.
2017-07-17add support for binary sysctl payloads by handling them as hex strings.David Gwynne
this was part of a demo showing how to implement the kernel side of sysctl(3) for setting Semantically Opaque Interface Identifier key material, but it seems to be the most straightforward path toward integrating soiikey handling and rc. ok florian@ sthen@ naddy@ tb@
2017-05-04Merge headers defining identifiers from sysctl.8 into sysctl.3. Shorten andTheo Buehler
update their descriptions. In sysctl.8 refer to /etc/sysctl.conf in FILES. discussed with and ok jmc
2017-04-25Use strtonum instead of strto{,u}ll for simpler and better overflowTheo Buehler
checking, make somaxconn and sominconn unsigned. Issue reported by orge on freenode, thanks! Input, patient explanations and ok deraadt, millert.

2017-03-11Introduce a new knob to force the first USB keyboard as console input.Martin Pieuchot
By setting "machdep.forceukbd=1" you can now use your USB keyboard in ddb(4) even if your BIOS emulates a pckbd(4). ok tom@, kettenis@, deraadt@

from rob pierce
2016-09-21sysctl KERN_ARND is no longer used (in ports, it only occurs in fallbackTheo de Raadt
paths of libevent). This interface was the first generation of what eventually became getentropy(2) and arc4random(3) -- june 1997! Ports scan by sthen, general agreement guenther

2016-07-27increase the size of forkstat fields to accomodate large valuesTed Unangst
2016-07-20Make the size for the syn cache hash array tunable. As we areAlexander Bluhm
swapping between two syn caches for random reseeding anyway, this feature can be added easily. When the cache is empty, there is an opportunity to change the hash size. This allows an admin under SYN flood attack to defend his machine. Suggested by claudio@; OK jung@ claudio@ jmc@

2016-05-19Remove sysctl net.inet6.ip6.v6onlyJeremie Courreges-Anglas
This sysctl is a no-op, read-only since it was introduced. There are no plans to support IPv4-mapped addresses on OpenBSD, thus this sysctl is meaningless. Noticed by djm@, ok claudio@ mpi@ sthen@ henning@

with the ip6intrq. ok claudio@
2015-01-16Replace <sys/param.h> with <limits.h> and other less dirty headers whereTheo de Raadt
possible. Annotate <sys/param.h> lines with their current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)

2014-11-19delete the KERN_VNODE sysctl. it fails to provide any isolation from theTed Unangst
kernel struct vnode defintion, and the only consumer (pstat) still needs kvm to read much of the required information. no great loss to always use kvm until there's a better replacement interface. ok deraadt millert uebayasi
