        !
      • pthreads(3) support:
        • The most significant change in this release is the replacement of the user-level uthreads by kernel-level rthreads, allowing multithreaded programs to utilize multiple CPUs/cores.
        • Use PTHREAD_MUTEX_STRICT_NP as default mutex type.
        • Added pthread spinlock and barrier routines. !
        • Added pthread_mutex_timedlock(3) and sem_timedwait(3). !
        • Added pthread_condattr_setclock(3). !
        • Added support for live multi-threaded debugging in gdb(1). !
        • Improved handling for rusage totals and interval timers in threaded processes. !
        • Changed the RLIMIT_NPROC rlimit to count processes instead of threads. !
        • Added a new system limit kern.maxthread for the max number of threads. !
        • Closed race conditions in thread creation, and in fork(2) and open(2) in a threaded process. !
        • Improved handling of threaded processes in ps(1), top(1), and fstat(1). !
        • Changed the lock around dlopen() to be recursive, so that dl*() operations from atexit() handlers don't deadlock.
        • Many fixes to pthread attribute and mutex error checking and cancellation handling.

      • Improved hardware support, including:
          !
        • Added hibernation support on i386. Currently only working on pciide(4) and wd(4) disks. !
        • Improved support for ALPS based touchpads in wsmouse(4) and the synaptics(4) X.Org input driver. !
        • Performance improvements with ix(4) Intel 10Gb Ethernet NICs. !
        • Support for i350 based devices in em(4). !
        • Flow control support for bnx(4). !
        • Hardware watchdog and HPET support for tcpcib(4) (Intel Atom E600) as found in some embedded x86 systems. !
        • urndis(4) supports additional Android devices. !
        • Support for Winbond W83627UHG has been added to wbsio(4). !
        • Support for the SMBus controller of the AMD CS5536 in glxpcib(4) and the NVIDIA MCP89 in nviic(4). !
        • Support for AX88772B based devices has been added to axe(4). !
        • Support for MCS7832 based devices has been added to mos(4). !
        • Support for the Roland UM-ONE has been added to umidi(4). !
        • Support for the AMD Hudson-2 chipset has been added to azalia(4) and piixpm(4). !
        • Support for NetMos NM9820 cardbus serial cards has been added to com(4). !
        • Support for Huawei Mobile E303 has been added to umsm(4).
        • The sgi port now supports the R4000 Indigo (IP20), Indy (IP22), R4000 Indigo2 (IP24) and POWER Indigo2 R10000 (IP28) families.

What's New

!

This is a partial list of new features and systems included in OpenBSD 5.2. For a comprehensive list, see the changelog leading to 5.2.

  • Routing daemons and other userland network improvements:

  • pf(4) improvements:

  • Assorted improvements:

  • Routing daemons and other userland network improvements:

    !

  • pf(4) improvements:

  • Assorted improvements: --- 233,268 ----
  • Added support for using AMT to provide console-over-Ethernet (c.f. the amtterm package).
  • Improved support for amd64 systems with many memory extents. !
  • compat_linux(8) improvements: TLS-vs-clone and futex fixes, added support for statfs64(), tgkill(), gettid(), SOCK_CLOEXEC, and SOCK_NONBLOCK. !
  • kdump(1) improvements, including the ability to show thread IDs and dumping of timespec, timeval, sigaction, rlimit, sigset, clockid, and fdset arguments and results. !
  • Various improvements in smtpd(8): reliability fixes, new MTA client, new scheduler and improved queue logic, simplified ! smtpd.conf(5) syntax, better RFC compliance and several cosmetic changes. !
  • The mg(1) emacs-like editor now supports cscope functionality. Also, backup files can now be saved to a user's home directory in addition to the current working directory. !
  • Fixed operation of kvm_getfile2() (and therefore fstat(1) and pstat(8)) on kernel crash dumps. !
  • Improved emacs-style key bindings and handling of large arrays in ksh(1). !
  • halt(8) disables "suspend-on-lid-close" so that you don't accidentally suspend instead of shutting down. !
  • Improvements to parallel make(1): added the .CHEAP and .EXPENSIVE special targets and fixed glitches in already-rebuilt logic. !
  • The libusb package is able to access non-ugen(4) devices for some operations, allowing e.g. programming YubiKeys with a standard kernel. !
  • Various improvements in tmux(1): a new unified tree view to select sessions or windows, new move-pane and renumber-windows commands, a history of pane layouts, simple output rate limiting, and custom formats (-F) have been extended and are now accepted by more commands. !
  • fsck_msdos(8) now works on devices with non-512 byte sectors. !
  • quotacheck(8) now works with DUID based fstab(5) files. !
  • Numerous minor improvement to fdisk(8), including more sanity checking and better default partition sizing on large disks. !
  • dhclient(8) now discards trailing NULs in option data, and in general parses option data with more paranoia. !
  • Various improvements to dhclient(8) startup and timeout handling. !
  • disklabel(8) does a better job of calculating physical memory during partition auto-allocation of devices with non-512 byte sectors. !
  • SCSI errors are now correctly propagated to userland, e.g. mount(2) now reports specific errors such as trying to mount RW filesystems from RO media.
  • Improved FAT media handling: autorecognize such media even if the 0x55aa signature is missing and prevent the writing of an OpenBSD disklabel over the FAT data structures.
  • The MS-DOS FAT filesystem implementation gained a significant write speedup for large files (up to twice as fast). *************** *** 260,307 ****

  • Many pre-built packages for each architecture: !

    Play with your BIOS options to enable booting from a CD. The OpenBSD/i386 release is on CD1. If your BIOS does not support booting from CD, you will need to create a boot floppy to install from. To create a boot floppy write *************** *** 468,493 **** To make a boot floppy under MS-DOS, use the "rawrite" utility located at CD1:5.2/tools/rawrite.exe. To make the boot floppy under a Unix OS, use the ! dd(1) utility. The following is an example usage of ! dd(1), where the device could be "floppy", "rfd0c", or "rfd0a". !

    Make sure you use properly formatted perfect floppies with NO BAD BLOCKS or your install will most likely fail. For more information on creating a boot floppy and installing OpenBSD/i386 please refer to this page. -
