Following -current

Table of Contents

Introduction

This document is for people who wish to follow -current. It contains information about changes from 4.3-release to -current, and should NOT be used by anyone upgrading from 4.2 or earlier, or people wishing to follow -stable.

If you wish to update to 4.3-release or 4.3-stable from previous versions, see the upgrade guide.

Make sure you have read and understood FAQ 5 - Building the System from Source before using -current and the instructions below.

You should ALWAYS use a snapshot as the starting point for running -current. Upgrading by compiling your own source code is not supported.

If you wish to see upgrade information for earlier versions of OpenBSD, see upgrade-old.html. This is provided as a historical record -- it should NOT be used as an upgrade procedure guide.

2008/03/23 - cwm configuration and command line options changed

The cwm(1) window manager got a new config parser, so the configuration needs to be changed according to cwmrc(5). The command line option "-f" (font) and "-s" (sticky) were replaced by config directives. Remove these options from your .xsession, or your xdm(1) login will fail!

2008/03/28 - landisk shared libraries enabled

To switch from static build on landisk to shared it is necessary to first build and install gcc and ld.so before building the rest of the system: 
# cd /usr/src/gnu/usr.bin/gcc
# make -f Makefile.bsd-wrapper obj
# make -f Makefile.bsd-wrapper depend
# make -f Makefile.bsd-wrapper
# make -f Makefile.bsd-wrapper install
# cd /usr/src/share/mk
# make install
# cd /usr/src/libexec/ld.so
# make obj
# make depend
# make
# make install
Then follow the release(8): directions to build the full system.

2008/04/21 - command line options for rtadvd(8) changed

The rtadvd(8) IPv6 router advertisement daemon had the command line options "-f" (foreground), "-d" (debug) and "-D" (even more debug). These options were merged to -d which does the same now as the combination of the three old options and is more OpenBSD-like.

2008/05/08 - file(1) updated, needs new /etc/magic

file(1) has been updated to a newer version which requires a new magic(5) file to be installed: 
# cd /tmp
# ftp ftp://mirror/path/to/snapshots/arch/etc43.tgz
# tar xzpf etc43.tgz ./etc/magic
# mv etc/magic /etc

2008/05/22 - spamd(8) sync mode protocol version changed

The protocol that spamd(8) uses when run in sync mode was changed to fix a number of bugs and the protocol version was incremented. Because of this, new versions of spamd can not sync with old versions (they will skip packets from one another). Therefore all instances in a spamd sync group must be upgraded at the same time.

2008/06/06 - httpd(8) manual moved

The Apache manual for httpd(8) has been moved out of /var/www/htdocs/manual/ to /usr/share/doc/html/httpd/. It has also been moved from the etcXX set to the miscXX file set.

2008/06/07 - support for dhcpd.interfaces removed

Support for /etc/dhcpd.interfaces has been removed. The file has been deprecated in favor of the dhcpd_flags setting in /etc/rc.conf.local.

2008/06/09 - nmeaattach(8) removed

The nmeaattach(8) command and the nmeaattach_flags option in /etc/rc.conf have been removed in -current. Use ldattach(8) instead. It has a slightly different synopsis than nmeaattach(8): nmeaattach cuaU0 becomes ldattach nmea cuaU0.

2008/06/09 New user and group _rtadvd

rtadvd(8) daemon now drops privileges after initialization to a new user and group _rtadvd. As root, add the user and group using useradd(8): 
useradd -u92 -g=uid -c"IPv6 Router Advertisement Daemon" -d/var/empty -s/sbin/nologin _rtadvd

2008/06/10 - per-address counters off by default on pf(4) tables

pf(4) tables now require the counters option in order to enable per-address byte and packet counters, eg:
table <webservers> counters { 192.168.33.4, 192.168.33.16/29 }
See pf.conf(5) for details.

2008/06/13 - mailmode in mg(1) removed

Because mail-mode in mg(1) was merely a buggy reimplementation of auto-fill-mode it has been removed. If you are using this please change your commands accordingly:
mail-mode => auto-fill-mode
mail-set-margin => set-fill-column
Don't forget to change your .mg file as well.

2008/06/16 - pfsync(4) version number incremented

Due to changes in the pf(4) state table, the pfsync(4) protocol version number has been incremented; firewalls with differing version numbers will be unable to synchronise state tables, and existing connections will be terminated on failover.

2008/07/09 - yacc(1) updated

A rebuild and install of yacc(1) is needed before doing a make build with a clean obj dir to make sure all yacc generated parsers get regenerated.

2008/07/10 - TCP/UDP baddynamic lists, sysctl(8), named(8) and /etc/rc

The kernel net.inet.tcp.baddynamic and net.inet.udp.baddynamic sysctls and the sysctl(8) utility have been extended to cover the full range of TCP/UDP ports. These lists identify source ports to never allocate dynamically so to avoid conflicts with well-known services. The /etc/rc script now automatically populates these lists from /etc/services at boot time.

The new version of named(8) (9.4.2-P1) that has just been imported uses random source ports for queries and requires this facility for robust operation.

To avoid any incompatibility, the kernel, sysctl(8), named(8) and /etc/rc should be updated in unison (build and install kernel before "make build").

2008/07/11 - openchrome(4) driver for Xenocara

The xf86-video-openchrome driver has been added to Xenocara for via chipsets in place of the old, obsolete, version of xf86-video-via that was there before.
If you're using a VIA chipset with a configuration file, replace
Driver "via"
with
Driver "openchrome"
in /etc/X11/xorg.conf to use the new driver. See the openchrome(4) manual page for more configuration options.

2008/07/11 - ati(4) video driver updated

The ati(4) driver has been updated. This update of xf86-video-ati brings about some important changes.

No more MergedFB:

Support for MergedFB mode has been removed in favor of xrandr(1).

Quirk option for Macbooks changed:

Users with Macs or Macbooks that use the following quirk 
Option      "iBookHacks" "on"
should read the radeon(4) man page, specifically the "MacModel" section, if there are problems.
As of this revision this quirk has been removed.

2008/07/19 - softraid metadata handling rewrite

The metadata handling in softraid(4) has been rewritten from scratch. The new code is not compatible with the old metadata format and hence users must backup and recreate their softraid volumes. Softraid volumes made prior to this change will not assemble when booting a kernel with this code.

2008/07/24 - changes in libc and libm

Due to the changes in libc and libm, the following steps have to be taken before the rest of the system is built.

0. Make sure you have obj.

# cd /usr/src
# make obj

1. Install headers, build and install libc.

# cd /usr/src/include
# make prereq
# make includes
# cd /usr/src/lib/libc
# make cleandir
# make depend
# make
# make install

2. Build and install libm.

# cd /usr/src/lib/libm
# make cleandir
# make depend
# make
# make install

3. Build and install libiberty.

# cd /usr/src/gnu/lib/libiberty
# make -f Makefile.bsd-wrapper cleandir
# make -f Makefile.bsd-wrapper depend
# make -f Makefile.bsd-wrapper
# make -f Makefile.bsd-wrapper install

4. Build and install gcc.

    If your platform uses gcc 2.95.3:
       # rm -r /usr/obj/gnu/egcs/gcc/*
       # cd /usr/src/gnu/egcs/gcc
        - or -
    If your platform uses gcc 3.3.5:

       # rm -r /usr/obj/gnu/usr.bin/gcc/*
       # cd /usr/src/gnu/usr.bin/gcc

    Common build procedure for v3.3.5 or v2.95.3
    # make -f Makefile.bsd-wrapper clean
    # make -f Makefile.bsd-wrapper obj
    # make -f Makefile.bsd-wrapper depend
    # make -f Makefile.bsd-wrapper
    # make -f Makefile.bsd-wrapper install
As usual, starting from a snapshot is CONSIDERABLY easier and highly recommended.
