4 directly to him. See end of file for further details.
7 Changes to the pccardd kernel interface require that you recompile
8 pccardd for new kernel.
11 The ipfw interface to the kernel has changed. You will need to
12 recompile ipfw programs for the new kernel.
15 The bpfilter device has been renamed to bpf. You will need to
16 change your config files in order to enable this in newer kernels.
19 src/contrib/sys/softupdates is moving to
20 src/sys/contrib/softupdates. Update your symbolic links/etc.
23 Major changes have been made to vinum and its interface. See
24 the man page (vinum(8)) for details. Look at the concat,
25 mirror and stripe commands, as well as the SIMPLIFIED
26 CONFIGURATION section.
29 Newsyslog.conf has had a minor, but potentially dangerous,
30 change to its username/group syntax. The old syntax was
31 user.group, while the new syntax is user:group.
34 Inetd wrapping default has changed. Please see the updated
38 Compaq Smart Raid driver committed as ida.
41 The second phase of syscons cleanup has happened. Some
42 functionality has been made optional. For details, see
43 http://www.freebsd.org/~yokota/sc_update-June.txt
44 Everyone will need to re-config(8) their kernels, but old
45 binaries will work with the new kernel.
48 IPFW uid/gid-based filtering support has been committed. This
49 breaks binary compatibility with previous copies of
50 ipfw(8). Any utilities using the ioctl()s of ipfw (especially
51 ipfw(8)) need to be recompiled with the newest headers
55 Inetd now wraps all stream-based services, including internals.
56 Syslog "severity" options are honoured. Installed syslog.conf
57 and hosts.allow should be checked.
60 Most of the problems with newbus have been corrected, but
61 it is still current and evolving.
63 libcam's ABI has changed. You must recompile the world and
64 any ports that use it.
67 Massive changes to SMP went into the tree that should speed
68 things up. However, if you experience problems with SMP
69 machines, you can back off to the PRE_SMP_VMSHARE tag in the
70 CVS repository (or run an MP kernel).
73 Pccardd and the pccard bus in general seem to be broken or
74 most people. Soren has patches to make it better for some,
75 but not all people. Work is underway to make it better for
79 new bus changes integrated into -current. Many problems were
80 initially reported, but most have been fixed. You'll need a
81 new config and to tweak your kernel config file the way that
82 GENERIC was tweaked. Keep a copy of your old kernel when
83 upgrading in case your new kernel doesn't work (and report the
84 breakage to current@freebsd.org).
86 As of 19990421 the remaining problems/quirks are
88 o sio no longer supports pnp nor pccard. This will be corrected,
89 but the new pccard code needs to be completed.
90 o Some of the sound drivers broke for some people. It seems
91 inconsistant as to who/what/when/where things broke.
92 o Duplicate device entries in your config do not work. Previously
93 they were silently ignored. psm0 seems to be the most common
94 duplicate choice, although some reports have come in from people
95 that wired their scsi disk entries.
96 o You must move the keyboard and mouse attachments from the
97 isa bus to the atkbdc bus. See GENERIC for details.
98 o Machines with multiple host-pci bridges (Intel 450NX) will not
99 probe the second pci bus.
100 o Some probe ordering may have changed, so device naming may change
101 with the new kernel. If you have multiple devices, please double
102 check to make sure they didn't move. This is especially true
103 for cards on different buses.
104 o The bus attachment for vga0 is always isa0 and never pci0 when
105 it is in fact a pci card. It is safe to ignore this.
106 o The format of the boot messages has changed (and is not
107 guaranteed to be constant for a while) so you may see this
108 in some shell scripts that diff dmesg from day to day as well
109 as scripts that parse dmesg output.
112 cc -aout sometimes has problems compiling with -g, remove -g
113 from those compilation units affected until this is corrected.
115 cc -aout has problems with producing some threaded libraries,
116 so make world -DWANT_AOUT is not functional at this time.
118 Since make world for a.out isn't functional, you cannot do
119 make aout-to-elf from a pre-egcs a.out system. To work around
120 this problem, make aout-to-elf using 3.1-stable first (or a
121 pre egcs -current) and then a simple make world will take you
122 the rest of the way with a -current source base.
125 Make -j works again for make world. As always, use it with
126 care, and be sure to try a make world w/o -j before reporting
127 problems (that is, know if the problem exists w/o -j before
128 reporting the problem with -j).
131 Note cc -aout, which had been broken since the conversion to
132 egcs, now supposedly works. If you have rebuilt things like
133 XFree86 a.out libraries, you should rebuild them again or
134 progams that use them, including netscape, will fail to work.
137 NOTE: New c++ compiler cannot be used with c++ binaries from
138 the old compiler and vice versa.
141 In recent days egcs has been imported into the tree. A number
142 of problems have been discussed in -current. Here is a highlight
143 of a few of the more common ones. With the exception of make
144 -j n, they have been claimed to have been fixed.
146 c++ is broken after make world: This is correct. Because we
147 changed compilers two make worlds are necessary to get C++
148 working again. The code generated by the old compiler and new
149 compiler are not compatible, so things wind up being
152 cpp is broken in make world: There was a window where cpp
153 would be built incorrectly. The fix for this is
154 cd src/gnu/usr.bin/cc
158 and this should correct your problems. See the -current
159 archives for a version of this that does moer cleaning.
161 Make -j n doesn't work. Work contiunes to make this work,
162 I've seen no reports of success as of April 7th.
165 Previously, one would define "NOAOUT" to keep from building
166 the legacy a.out bits. Now one would define "WANT_AOUT" to
170 The name of the old wd.c and atapi.c based CDROM driver has
171 been changed back to wcd. So update your config file to use
172 "device wcd" instead of "device acd".
175 For those of you using the VN device as a loadable module,
176 please be aware that the new VN device has been committed to
177 -4.x and cannot yet be used as a loadable module. This will
178 be fixed in the future.
181 New loader.rc mechanism. Please see src/sys/boot/README for
185 struct proc size changed. Recompile kernel and the
186 usual suspects. Make world if in doubt.
189 The nlpt driver has changed names back to be the lpt driver.
190 See ppbus(4) or http://www.freebsd.org/~nsouch/ppbus.html
191 for proper configuration details.
194 The 'lpt' driver is now obsolete. Replace it with the 'nlpt'
195 driver and 'ppbus' controller combination.
198 New devstat API requires recompilation of libdevstat, systat,
199 iostat, vmstat and rpc.rstatd. A new kernel is also required.
200 make world + building a kernel should do all of this. Any
201 ports that use devstat need to be recompiled as well.
204 Linux threads options has gone away (they are now standard in
205 the FreeBSD kernel). A recompile of all libkvm using programs
206 is in order (or better yet a make world).
209 On or about this date there was a small window when the boot
210 blocks had some minor problems which seemed to force one to
211 edit /etc/fstab. This has been corrected, if you are seeing this
212 problem, please rebuild and reinstall your boot blocks.
215 Vinum has changed. The "vinum read" command has changed. For
218 http://www.freebsd.org/cgi/getmsg.cgi?fetch=800363+0+current/freebsd-current
222 Matt Dillon committed a boatload of VM changes, for
223 information please see
225 http://www.freebsd.org/cgi/getmsg.cgi?fetch=886676+0+current/freebsd-current
227 http://www.freebsd.org/cgi/getmsg.cgi?fetch=827400+0+current/freebsd-current
229 for details. These changes will likely not impact anybody,
230 but large chagnes to the VM need at least a heads up.
233 Stable branch created. You might want to consider using this
234 branch. It is tagged with RELENG_3.
237 More work on the syscons driver has been committed. Since
238 files moved around, you will need to reconfigure your kernel,
239 and make clean; make depend before rebuilding the kernel. No
240 config file changes are needed.
243 New keyboard and video card drivers are introduced as the first
244 stage of console driver reorganization. You are required to
245 update the kernel configuration file and rebuild the kernel.
246 kbdcontrol, vidcontrol, and screen savers also need recompilation.
247 The instruction can be found in
249 http://www.freebsd.org/~yokota/sc_update.txt
251 It has notes on splash screen too.
254 Robert Nordier was kind enough to make this page to enable people to
255 install the new bootblocks:
257 http://www.freebsd.org/~rnordier/boot.txt
259 When updating to ELF, make sure that you have updated your
260 /etc/rc files which have different ldconfig invocations for
261 elf and aout. Otherwise things like X will stop working with
262 messages about being unable to find library files. The
263 mergemaster utility in ports/sysutils/mergemaster helps to
264 keep critical files like this in sync, and its use is
268 Information about ELF day (see 19981230) can be found in
270 http://www.freebsd.org/~peter/elfday.html
272 about the upcoming change, its motivations and instructions
273 for doing the upgrade.
276 You should install new bootblocks now. The ELF kernel will
277 become default soon. In addition, you'll need to upgrade
278 your userland programs to ELF before then as well. Use
279 make aout-to-elf to upgrade your userland programs (old
280 a.out programs in, for example, /usr/local/bin will
281 continue to work, even after the upgrade). See src/Makefile
285 The old wcd driver has been deleted from the kernel. The
286 driver that replaces it is named acd. You'll need to change
287 this in your configuration files.
289 Failure to do this will result in "ATAPI CD-ROMs not
290 configured" at boot time.
292 The floppy tape driver (ft) has been removed from the kernel,
293 with no replacement driver.
296 New groups from 19981201 commented out of mtree, so they
297 aren't strictly needed, but still a good idea to have.
300 New user/group added: bind. From src/etc/master.passwd and
302 % grep <newstuff> /usr/src/etc/group
304 % grep <newstuff> /usr/src/etc/master.passwd
305 tty:*:4:65533::0:0:Tty Sandbox:/:/sbin/nologin
306 kmem:*:5:65533::0:0:KMem Sandbox:/:/sbin/nologin
307 bind:*:53:53::0:0:Bind Sandbox:/:/sbin/nologin
310 PAM integrated into the tree. Requires new /etc/pam.conf file
311 to silence warnings from authentication programs (login, etc).
312 See src/etc/pam.conf for a sample.
314 This file contains a list, in reverse chronologocal order, of major
315 breakages in tracking -current. Not all things will be listed here,
316 and it only starts on Novemeber 18, 1998. If you have an earlier
317 version of FreeBSD, you are on your own to get to November 18, 1998.
319 Please filter your entries through Warner (imp@village.org) so that
