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@

2016-07-20Make the size for the syn cache hash array tunable. As we arebluhm1-4/+6
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.v6onlyjca1-3/+2
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 autoconf enabled. If one is doing SLAAC one does already trust link local icmp6 so the policy for icmp6 redirects should be the same. pointed out by & OK bluhm@; OK henning@

2014-05-04When kern.nosuidcoredump=3, act like =2 but try to dump cores intoderaadt1-2/+14
the /var/crash/programname/ directory, as root. For instance, # mkdir /var/crash/bgpd/ # chmod 700 /var/crash/bgpd/ # If you skip this step, you are a moron # sysctl kern.nosuidcoredump=3 # bgpd # pkill -ABRT bgpd # ls /var/crash/bgpd/ 14764.core 23207.core 6423.core Of course, in real life the idea is that you don't kill the daemon but it crashes and you collect parallel cores. Careful you don't fill your /var. Further tuneables are being considered. Sorry to be picking on bgpd for this example. I've watched the "too difficult to debug privsep code" angst for far too long. ok guenther

2013-01-03sysctl.3: remove some confusing text about NFS_NIOTHREADSjmc1-16/+2
sysctl.8: remove the vfs.nfs.iothreads example, since a) showing how to set a default value is not particularly helpful and b) EXAMPLES is bloated enough as it is; further, remove the text which points to other pages for further discussion, since those pages no longer provide relevant info diff started by an email from Jan Stary; blambert helped me prepare this diff
