OpenBSD

Il progetto OpenBSD è sistema operativo UNIX basato su 4.4 BSD ed è gratuito e multipiattaforma. OpenBSD supporta l’emulazione binaria di molti programmi da Solaris, FreeBSD, Linux, BSD/OS, SunOS e HP-UX.

Versione 5.7

Questa versione contiene (in Inglese):

  • Update unbound(8) to 1.5.0.
  • In mandoc(1), make .Ao and .Aq renders as “<>” after .An, and as “\(la\(ra” elsewhere, just like groff.

  • Delete KERN_VNODE sysctl(3).
  • Add support for exporting relayd(8) statistics via AgentX/snmpd(8).
  • Add support for AgentX subagents in snmpd(8).
  • Fix ssl memory leak with pkey in client key exchange.
  • Bugfix for grdc(6) to run for the specified amount of seconds, not for a fixed amount of iterations. Makes a difference on slow terminals.
  • Make mandoc(1) let escape sequences terminate high-level macro names, and when doing so, they are ignored.

  • For newer re(4) chipsets, add support for stopping the operation within re_stop().
  • Let mandoc(1) support the “.if v” conditional operater for groff compatibility.
  • Sync ssh(1) AES code to the one shipped with OpenSSL/LibreSSL.
  • Make binutils recognize dcbzl for PPC code, backported from 2.17.
  • Disable the page zeroing thread on MP mips64 kernels.
