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 Gcc 2.95.2 is now the default compiler.
10 PCCARD has been updated to attach pcic to the isa bus. Therefore
11 you will need to modify kernel config files that have pcic/card
13 controller pcic0 at isa?
14 controller pcic1 at isa?
18 The sigset_t datatype has been changed from an integral type
19 to a compound type and can hold 128 signals. Syscalls directly
20 or indirectly using the new sigset_t have been added as to
21 maintain compatibility with existing binaries. A new kernel must
22 be made and installed and booted with before a make world can
26 New jail syscall format requires recompilation of jail(8) with
27 fresh headers installed (or a make world will do it for you).
30 Matt Dillon checked in many vm related things and sent a heads up
31 to -current urging caution and to report vm problems to him.
32 As of the 19th, no killer problems have been reported, but you
36 The new miibus has been added to the system. If you are using
37 the dm, rl, sf, sis, ste, tl, wb or xl drivers, you need to
38 add "controller miibus0" to your config file.
41 /var/cron/log has been moved to /var/log/cron to get all the
42 log files in one place.
45 tn3270 has been removed from the based system and added as a port.
48 User-visible TCP timers are now expressed in units of 1ms, instead
49 of 500ms, so if you've customized any timer values under
50 ``net.inet.tcp'', multiply them by 500 to preserve TCP's behavior.
53 RCS Id tags changed to FreeBSD. This will cause huge cvsup
57 On 28-May-1999 libreadline was upgraded from readline-2.2 to
58 readline-4.0. At that time the shared library major version
59 number was bumped from "3" to "4". It has been deemed that
60 the interface change between readline-2.2 and readline-4.0 was
61 not sufficient to warrant the version number bump.
63 Thus I have reverted it back to "3". You will need to perform
64 the below immediately before your next ``make world'':
66 ls -l libreadline.so.4
67 (if you have /usr/lib/libreadline.so.4)
68 mv libreadline.so.4 libreadline.so.3
70 ln -s libreadline.so.3 libreadline.so
73 Changes to the pccardd kernel interface require that you recompile
74 pccardd for new kernel.
77 The ipfw interface to the kernel has changed. You will need to
78 recompile ipfw programs for the new kernel.
81 The bpfilter device has been renamed to bpf. You will need to
82 change your config files in order to enable this in newer kernels.
85 src/contrib/sys/softupdates is moving to
86 src/sys/contrib/softupdates. Update your symbolic links/etc.
89 Major changes have been made to vinum and its interface. See
90 the man page (vinum(8)) for details. Look at the concat,
91 mirror and stripe commands, as well as the SIMPLIFIED
92 CONFIGURATION section.
95 Newsyslog.conf has had a minor, but potentially dangerous,
96 change to its username/group syntax. The old syntax was
97 user.group, while the new syntax is user:group.
100 Inetd wrapping default has changed. Please see the updated
101 man page for details.
104 Compaq Smart Raid driver committed as ida.
107 The second phase of syscons cleanup has happened. Some
108 functionality has been made optional. For details, see
109 http://www.freebsd.org/~yokota/sc_update-June.txt
110 Everyone will need to re-config(8) their kernels, but old
111 binaries will work with the new kernel.
114 IPFW uid/gid-based filtering support has been committed. This
115 breaks binary compatibility with previous copies of
116 ipfw(8). Any utilities using the ioctl()s of ipfw (especially
117 ipfw(8)) need to be recompiled with the newest headers
121 Inetd now wraps all stream-based services, including internals.
122 Syslog "severity" options are honoured. Installed syslog.conf
123 and hosts.allow should be checked.
126 Most of the problems with newbus have been corrected, but
127 it is still current and evolving.
129 libcam's ABI has changed. You must recompile the world and
130 any ports that use it.
133 Massive changes to SMP went into the tree that should speed
134 things up. However, if you experience problems with SMP
135 machines, you can back off to the PRE_SMP_VMSHARE tag in the
136 CVS repository (or run an MP kernel).
139 Pccardd and the pccard bus in general seem to be broken or
140 most people. Soren has patches to make it better for some,
141 but not all people. Work is underway to make it better for
145 new bus changes integrated into -current. Many problems were
146 initially reported, but most have been fixed. You'll need a
147 new config and to tweak your kernel config file the way that
148 GENERIC was tweaked. Keep a copy of your old kernel when
149 upgrading in case your new kernel doesn't work (and report the
150 breakage to current@freebsd.org).
152 As of 19990421 the remaining problems/quirks are
154 o sio no longer supports pnp nor pccard. This will be corrected,
155 but the new pccard code needs to be completed.
156 o Some of the sound drivers broke for some people. It seems
157 inconsistant as to who/what/when/where things broke.
158 o Duplicate device entries in your config do not work. Previously
159 they were silently ignored. psm0 seems to be the most common
160 duplicate choice, although some reports have come in from people
161 that wired their scsi disk entries.
162 o You must move the keyboard and mouse attachments from the
163 isa bus to the atkbdc bus. See GENERIC for details.
164 o Machines with multiple host-pci bridges (Intel 450NX) will not
165 probe the second pci bus.
166 o Some probe ordering may have changed, so device naming may change
167 with the new kernel. If you have multiple devices, please double
168 check to make sure they didn't move. This is especially true
169 for cards on different buses.
170 o The bus attachment for vga0 is always isa0 and never pci0 when
171 it is in fact a pci card. It is safe to ignore this.
172 o The format of the boot messages has changed (and is not
173 guaranteed to be constant for a while) so you may see this
174 in some shell scripts that diff dmesg from day to day as well
175 as scripts that parse dmesg output.
178 cc -aout sometimes has problems compiling with -g, remove -g
179 from those compilation units affected until this is corrected.
181 cc -aout has problems with producing some threaded libraries,
182 so make world -DWANT_AOUT is not functional at this time.
184 Since make world for a.out isn't functional, you cannot do
185 make aout-to-elf from a pre-egcs a.out system. To work around
186 this problem, make aout-to-elf using 3.1-stable first (or a
187 pre egcs -current) and then a simple make world will take you
188 the rest of the way with a -current source base.
191 Make -j works again for make world. As always, use it with
192 care, and be sure to try a make world w/o -j before reporting
193 problems (that is, know if the problem exists w/o -j before
194 reporting the problem with -j).
197 Note cc -aout, which had been broken since the conversion to
198 egcs, now supposedly works. If you have rebuilt things like
199 XFree86 a.out libraries, you should rebuild them again or
200 progams that use them, including netscape, will fail to work.
203 NOTE: New c++ compiler cannot be used with c++ binaries from
204 the old compiler and vice versa.
207 In recent days egcs has been imported into the tree. A number
208 of problems have been discussed in -current. Here is a highlight
209 of a few of the more common ones. With the exception of make
210 -j n, they have been claimed to have been fixed.
212 c++ is broken after make world: This is correct. Because we
213 changed compilers two make worlds are necessary to get C++
214 working again. The code generated by the old compiler and new
215 compiler are not compatible, so things wind up being
218 cpp is broken in make world: There was a window where cpp
219 would be built incorrectly. The fix for this is
220 cd src/gnu/usr.bin/cc
224 and this should correct your problems. See the -current
225 archives for a version of this that does moer cleaning.
227 Make -j n doesn't work. Work contiunes to make this work,
228 I've seen no reports of success as of April 7th.
231 Previously, one would define "NOAOUT" to keep from building
232 the legacy a.out bits. Now one would define "WANT_AOUT" to
236 The name of the old wd.c and atapi.c based CDROM driver has
237 been changed back to wcd. So update your config file to use
238 "device wcd" instead of "device acd".
241 For those of you using the VN device as a loadable module,
242 please be aware that the new VN device has been committed to
243 -4.x and cannot yet be used as a loadable module. This will
244 be fixed in the future.
247 New loader.rc mechanism. Please see src/sys/boot/README for
251 struct proc size changed. Recompile kernel and the
252 usual suspects. Make world if in doubt.
255 The nlpt driver has changed names back to be the lpt driver.
256 See ppbus(4) or http://www.freebsd.org/~nsouch/ppbus.html
257 for proper configuration details.
260 The 'lpt' driver is now obsolete. Replace it with the 'nlpt'
261 driver and 'ppbus' controller combination.
264 New devstat API requires recompilation of libdevstat, systat,
265 iostat, vmstat and rpc.rstatd. A new kernel is also required.
266 make world + building a kernel should do all of this. Any
267 ports that use devstat need to be recompiled as well.
270 Linux threads options has gone away (they are now standard in
271 the FreeBSD kernel). A recompile of all libkvm using programs
272 is in order (or better yet a make world).
275 On or about this date there was a small window when the boot
276 blocks had some minor problems which seemed to force one to
277 edit /etc/fstab. This has been corrected, if you are seeing this
278 problem, please rebuild and reinstall your boot blocks.
281 Vinum has changed. The "vinum read" command has changed. For
284 http://www.freebsd.org/cgi/getmsg.cgi?fetch=800363+0+current/freebsd-current
288 Matt Dillon committed a boatload of VM changes, for
289 information please see
291 http://www.freebsd.org/cgi/getmsg.cgi?fetch=886676+0+current/freebsd-current
293 http://www.freebsd.org/cgi/getmsg.cgi?fetch=827400+0+current/freebsd-current
295 for details. These changes will likely not impact anybody,
296 but large chagnes to the VM need at least a heads up.
299 Stable branch created. You might want to consider using this
300 branch. It is tagged with RELENG_3.
303 More work on the syscons driver has been committed. Since
304 files moved around, you will need to reconfigure your kernel,
305 and make clean; make depend before rebuilding the kernel. No
306 config file changes are needed.
309 New keyboard and video card drivers are introduced as the first
310 stage of console driver reorganization. You are required to
311 update the kernel configuration file and rebuild the kernel.
312 kbdcontrol, vidcontrol, and screen savers also need recompilation.
313 The instruction can be found in
315 http://www.freebsd.org/~yokota/sc_update.txt
317 It has notes on splash screen too.
320 Robert Nordier was kind enough to make this page to enable people to
321 install the new bootblocks:
323 http://www.freebsd.org/~rnordier/boot.txt
325 When updating to ELF, make sure that you have updated your
326 /etc/rc files which have different ldconfig invocations for
327 elf and aout. Otherwise things like X will stop working with
328 messages about being unable to find library files. The
329 mergemaster utility in ports/sysutils/mergemaster helps to
330 keep critical files like this in sync, and its use is
334 Information about ELF day (see 19981230) can be found in
336 http://www.freebsd.org/~peter/elfday.html
338 about the upcoming change, its motivations and instructions
339 for doing the upgrade.
342 You should install new bootblocks now. The ELF kernel will
343 become default soon. In addition, you'll need to upgrade
344 your userland programs to ELF before then as well. Use
345 make aout-to-elf to upgrade your userland programs (old
346 a.out programs in, for example, /usr/local/bin will
347 continue to work, even after the upgrade). See src/Makefile
351 The old wcd driver has been deleted from the kernel. The
352 driver that replaces it is named acd. You'll need to change
353 this in your configuration files.
355 Failure to do this will result in "ATAPI CD-ROMs not
356 configured" at boot time.
358 The floppy tape driver (ft) has been removed from the kernel,
359 with no replacement driver.
362 New groups from 19981201 commented out of mtree, so they
363 aren't strictly needed, but still a good idea to have.
366 New user/group added: bind. From src/etc/master.passwd and
368 % grep <newstuff> /usr/src/etc/group
370 % grep <newstuff> /usr/src/etc/master.passwd
371 tty:*:4:65533::0:0:Tty Sandbox:/:/sbin/nologin
372 kmem:*:5:65533::0:0:KMem Sandbox:/:/sbin/nologin
373 bind:*:53:53::0:0:Bind Sandbox:/:/sbin/nologin
376 PAM integrated into the tree. Requires new /etc/pam.conf file
377 to silence warnings from authentication programs (login, etc).
378 See src/etc/pam.conf for a sample.
380 This file contains a list, in reverse chronologocal order, of major
381 breakages in tracking -current. Not all things will be listed here,
382 and it only starts on November 18, 1998. If you have an earlier
383 version of FreeBSD, you are on your own to get to November 18, 1998.
385 Please filter your entries through Warner (imp@village.org) so that
