1 Updating Information for FreeBSD current users
3 This file is maintained by imp@village.org. Please send new entries
4 directly to him. See end of file for further details.
7 The new miibus has been added to the system. If you are using
8 the dm, rl, sf, sis, ste, tl, wb or xl drivers, you need to
9 add "controller miibus0" to your config file.
12 /var/cron/log has been moved to /var/log/cron to get all the
13 log files in one place.
16 tn3270 has been removed from the based system and added as a port.
19 User-visible TCP timers are now expressed in units of 1ms, instead
20 of 500ms, so if you've customized any timer values under
21 ``net.inet.tcp'', multiply them by 500 to preserve TCP's behavior.
24 RCS Id tags changed to FreeBSD. This will cause huge cvsup
28 On 28-May-1999 libreadline was upgraded from readline-2.2 to
29 readline-4.0. At that time the shared library major version
30 number was bumped from "3" to "4". It has been deemed that
31 the interface change between readline-2.2 and readline-4.0 was
32 not suffient to warrant the version number bump.
34 Thus I have reverted it back to "3". You will need to perform
35 the below immediately before your next ``make world'':
37 ls -l libreadline.so.4
38 (if you have /usr/lib/libreadline.so.4)
39 mv libreadline.so.4 libreadline.so.3
41 ln -s libreadline.so.3 libreadline.so
44 Changes to the pccardd kernel interface require that you recompile
45 pccardd for new kernel.
48 The ipfw interface to the kernel has changed. You will need to
49 recompile ipfw programs for the new kernel.
52 The bpfilter device has been renamed to bpf. You will need to
53 change your config files in order to enable this in newer kernels.
56 src/contrib/sys/softupdates is moving to
57 src/sys/contrib/softupdates. Update your symbolic links/etc.
60 Major changes have been made to vinum and its interface. See
61 the man page (vinum(8)) for details. Look at the concat,
62 mirror and stripe commands, as well as the SIMPLIFIED
63 CONFIGURATION section.
66 Newsyslog.conf has had a minor, but potentially dangerous,
67 change to its username/group syntax. The old syntax was
68 user.group, while the new syntax is user:group.
71 Inetd wrapping default has changed. Please see the updated
75 Compaq Smart Raid driver committed as ida.
78 The second phase of syscons cleanup has happened. Some
79 functionality has been made optional. For details, see
80 http://www.freebsd.org/~yokota/sc_update-June.txt
81 Everyone will need to re-config(8) their kernels, but old
82 binaries will work with the new kernel.
85 IPFW uid/gid-based filtering support has been committed. This
86 breaks binary compatibility with previous copies of
87 ipfw(8). Any utilities using the ioctl()s of ipfw (especially
88 ipfw(8)) need to be recompiled with the newest headers
92 Inetd now wraps all stream-based services, including internals.
93 Syslog "severity" options are honoured. Installed syslog.conf
94 and hosts.allow should be checked.
97 Most of the problems with newbus have been corrected, but
98 it is still current and evolving.
100 libcam's ABI has changed. You must recompile the world and
101 any ports that use it.
104 Massive changes to SMP went into the tree that should speed
105 things up. However, if you experience problems with SMP
106 machines, you can back off to the PRE_SMP_VMSHARE tag in the
107 CVS repository (or run an MP kernel).
110 Pccardd and the pccard bus in general seem to be broken or
111 most people. Soren has patches to make it better for some,
112 but not all people. Work is underway to make it better for
116 new bus changes integrated into -current. Many problems were
117 initially reported, but most have been fixed. You'll need a
118 new config and to tweak your kernel config file the way that
119 GENERIC was tweaked. Keep a copy of your old kernel when
120 upgrading in case your new kernel doesn't work (and report the
121 breakage to current@freebsd.org).
123 As of 19990421 the remaining problems/quirks are
125 o sio no longer supports pnp nor pccard. This will be corrected,
126 but the new pccard code needs to be completed.
127 o Some of the sound drivers broke for some people. It seems
128 inconsistant as to who/what/when/where things broke.
129 o Duplicate device entries in your config do not work. Previously
130 they were silently ignored. psm0 seems to be the most common
131 duplicate choice, although some reports have come in from people
132 that wired their scsi disk entries.
133 o You must move the keyboard and mouse attachments from the
134 isa bus to the atkbdc bus. See GENERIC for details.
135 o Machines with multiple host-pci bridges (Intel 450NX) will not
136 probe the second pci bus.
137 o Some probe ordering may have changed, so device naming may change
138 with the new kernel. If you have multiple devices, please double
139 check to make sure they didn't move. This is especially true
140 for cards on different buses.
141 o The bus attachment for vga0 is always isa0 and never pci0 when
142 it is in fact a pci card. It is safe to ignore this.
143 o The format of the boot messages has changed (and is not
144 guaranteed to be constant for a while) so you may see this
145 in some shell scripts that diff dmesg from day to day as well
146 as scripts that parse dmesg output.
149 cc -aout sometimes has problems compiling with -g, remove -g
150 from those compilation units affected until this is corrected.
152 cc -aout has problems with producing some threaded libraries,
153 so make world -DWANT_AOUT is not functional at this time.
155 Since make world for a.out isn't functional, you cannot do
156 make aout-to-elf from a pre-egcs a.out system. To work around
157 this problem, make aout-to-elf using 3.1-stable first (or a
158 pre egcs -current) and then a simple make world will take you
159 the rest of the way with a -current source base.
162 Make -j works again for make world. As always, use it with
163 care, and be sure to try a make world w/o -j before reporting
164 problems (that is, know if the problem exists w/o -j before
165 reporting the problem with -j).
168 Note cc -aout, which had been broken since the conversion to
169 egcs, now supposedly works. If you have rebuilt things like
170 XFree86 a.out libraries, you should rebuild them again or
171 progams that use them, including netscape, will fail to work.
174 NOTE: New c++ compiler cannot be used with c++ binaries from
175 the old compiler and vice versa.
178 In recent days egcs has been imported into the tree. A number
179 of problems have been discussed in -current. Here is a highlight
180 of a few of the more common ones. With the exception of make
181 -j n, they have been claimed to have been fixed.
183 c++ is broken after make world: This is correct. Because we
184 changed compilers two make worlds are necessary to get C++
185 working again. The code generated by the old compiler and new
186 compiler are not compatible, so things wind up being
189 cpp is broken in make world: There was a window where cpp
190 would be built incorrectly. The fix for this is
191 cd src/gnu/usr.bin/cc
195 and this should correct your problems. See the -current
196 archives for a version of this that does moer cleaning.
198 Make -j n doesn't work. Work contiunes to make this work,
199 I've seen no reports of success as of April 7th.
202 Previously, one would define "NOAOUT" to keep from building
203 the legacy a.out bits. Now one would define "WANT_AOUT" to
207 The name of the old wd.c and atapi.c based CDROM driver has
208 been changed back to wcd. So update your config file to use
209 "device wcd" instead of "device acd".
212 For those of you using the VN device as a loadable module,
213 please be aware that the new VN device has been committed to
214 -4.x and cannot yet be used as a loadable module. This will
215 be fixed in the future.
218 New loader.rc mechanism. Please see src/sys/boot/README for
222 struct proc size changed. Recompile kernel and the
223 usual suspects. Make world if in doubt.
226 The nlpt driver has changed names back to be the lpt driver.
227 See ppbus(4) or http://www.freebsd.org/~nsouch/ppbus.html
228 for proper configuration details.
231 The 'lpt' driver is now obsolete. Replace it with the 'nlpt'
232 driver and 'ppbus' controller combination.
235 New devstat API requires recompilation of libdevstat, systat,
236 iostat, vmstat and rpc.rstatd. A new kernel is also required.
237 make world + building a kernel should do all of this. Any
238 ports that use devstat need to be recompiled as well.
241 Linux threads options has gone away (they are now standard in
242 the FreeBSD kernel). A recompile of all libkvm using programs
243 is in order (or better yet a make world).
246 On or about this date there was a small window when the boot
247 blocks had some minor problems which seemed to force one to
248 edit /etc/fstab. This has been corrected, if you are seeing this
249 problem, please rebuild and reinstall your boot blocks.
252 Vinum has changed. The "vinum read" command has changed. For
255 http://www.freebsd.org/cgi/getmsg.cgi?fetch=800363+0+current/freebsd-current
259 Matt Dillon committed a boatload of VM changes, for
260 information please see
262 http://www.freebsd.org/cgi/getmsg.cgi?fetch=886676+0+current/freebsd-current
264 http://www.freebsd.org/cgi/getmsg.cgi?fetch=827400+0+current/freebsd-current
266 for details. These changes will likely not impact anybody,
267 but large chagnes to the VM need at least a heads up.
270 Stable branch created. You might want to consider using this
271 branch. It is tagged with RELENG_3.
274 More work on the syscons driver has been committed. Since
275 files moved around, you will need to reconfigure your kernel,
276 and make clean; make depend before rebuilding the kernel. No
277 config file changes are needed.
280 New keyboard and video card drivers are introduced as the first
281 stage of console driver reorganization. You are required to
282 update the kernel configuration file and rebuild the kernel.
283 kbdcontrol, vidcontrol, and screen savers also need recompilation.
284 The instruction can be found in
286 http://www.freebsd.org/~yokota/sc_update.txt
288 It has notes on splash screen too.
291 Robert Nordier was kind enough to make this page to enable people to
292 install the new bootblocks:
294 http://www.freebsd.org/~rnordier/boot.txt
296 When updating to ELF, make sure that you have updated your
297 /etc/rc files which have different ldconfig invocations for
298 elf and aout. Otherwise things like X will stop working with
299 messages about being unable to find library files. The
300 mergemaster utility in ports/sysutils/mergemaster helps to
301 keep critical files like this in sync, and its use is
305 Information about ELF day (see 19981230) can be found in
307 http://www.freebsd.org/~peter/elfday.html
309 about the upcoming change, its motivations and instructions
310 for doing the upgrade.
313 You should install new bootblocks now. The ELF kernel will
314 become default soon. In addition, you'll need to upgrade
315 your userland programs to ELF before then as well. Use
316 make aout-to-elf to upgrade your userland programs (old
317 a.out programs in, for example, /usr/local/bin will
318 continue to work, even after the upgrade). See src/Makefile
322 The old wcd driver has been deleted from the kernel. The
323 driver that replaces it is named acd. You'll need to change
324 this in your configuration files.
326 Failure to do this will result in "ATAPI CD-ROMs not
327 configured" at boot time.
329 The floppy tape driver (ft) has been removed from the kernel,
330 with no replacement driver.
333 New groups from 19981201 commented out of mtree, so they
334 aren't strictly needed, but still a good idea to have.
337 New user/group added: bind. From src/etc/master.passwd and
339 % grep <newstuff> /usr/src/etc/group
341 % grep <newstuff> /usr/src/etc/master.passwd
342 tty:*:4:65533::0:0:Tty Sandbox:/:/sbin/nologin
343 kmem:*:5:65533::0:0:KMem Sandbox:/:/sbin/nologin
344 bind:*:53:53::0:0:Bind Sandbox:/:/sbin/nologin
347 PAM integrated into the tree. Requires new /etc/pam.conf file
348 to silence warnings from authentication programs (login, etc).
349 See src/etc/pam.conf for a sample.
351 This file contains a list, in reverse chronologocal order, of major
352 breakages in tracking -current. Not all things will be listed here,
353 and it only starts on Novemeber 18, 1998. If you have an earlier
354 version of FreeBSD, you are on your own to get to November 18, 1998.
356 Please filter your entries through Warner (imp@village.org) so that
