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 sendmail.cf has moved from /etc/sendmail.cf to
8 /etc/mail/sendmail.cf. You may need to adjust /etc/rc.conf to
9 cope as well as moving sendmail.cf.
12 ntp 4.0.98 has replaced the ancient xntpd. The daemon named
13 changed from xntpd to ntpd, so you may need to update your
14 /etc/rc.conf file. The ntp.conf files are compatible with the
15 old release, unless you are using a local reference clock.
16 Details about ntp4 can be found at http://www.ntp.org/.
18 xntpd will be cvs removed from the repo in about a week.
21 Soren updated the ata driver. Please update to at least this
22 version before submitting bug reports.
25 The ata driver has become the primary ata/ide/atapi driver in
26 the kernel. The wd driver is obsolete. You should upgrade your
27 machine to the new ata driver. You will need to follow the
28 directions for updating the devices in the 19991205 entry. You
29 will need to update all occurances of wd to ad in your config files
30 (/etc/rc.conf, /etc/fstab, etc). A compatibility device exists
31 for wd for the time being, but once you have determined that
32 ata is working for you, transition to the new ad devices.
35 Block devices are going away. You will need to update your /dev
36 tree with a fresh copy of MAKEDEV for things to always work in
37 the future. fsck is unable to cope with dirty file systems
38 after this change, so it may work for you or it may not.
40 MAKEDEV should be copied from src/etc/MAKEDEV to /dev before
41 starting the following:
43 For N in the list of disks
45 for M in the list of slices
46 MAKEDEV NsMa # eg ad0s1a
48 *** All uses of block devices must be converted to char devices.
49 *** Likely the only thing impacted is dumpdev in /etc/rc.conf
52 The dc interface has replaced al, ax, dm, pn and mx. The former
56 Support for the old 'sd' device names has been removed in
57 favor of 'da'. Please update your /etc/fstab, /etc/rc.conf
58 and any other places you might have sd names cached.
59 Generally these changes are as simple as s=/dev/sd=/dev/da=g,
60 but be careful to make sure that things are really that
61 simple. You may also need to create /dev entries for the da
64 MAKEDEV should be copied from src/etc/MAKEDEV to /dev before
65 starting the following:
67 For N in the list of da disks on your system
69 for M in the list of slices
72 BAD144 support has been removed. Cope or replace the hardware.
75 ALPHA users take note. All klds will need to be recompiled for
76 kernels build after this date. It is a good time to update since
77 pal.s will be going away soon.
80 MFS_ROOT and MFS_ROOT_SIZE are gone, replaced by MD_ROOT and
81 MD_ROOT_SIZE options in the md driver. md driver now deals with
82 the hacks. You should add md driver to kerneles that have
83 MFS_ROOT, et al. See GENERIC or LINT for details.
86 The ep changed a while ago and can no longer be used with hard
87 wired addresses in the config file.
90 The bridge drivers for sound cards have been committed. Please
91 see LINT for instructions for your card, if it still works at
95 Gcc 2.95.2 is now the default compiler.
98 PCCARD has been updated to attach pcic to the isa bus. Therefore
99 you will need to modify kernel config files that have pcic/card
101 controller pcic0 at isa?
102 controller pcic1 at isa?
106 The sigset_t datatype has been changed from an integral type
107 to a compound type and can hold 128 signals. Syscalls directly
108 or indirectly using the new sigset_t have been added as to
109 maintain compatibility with existing binaries. A new kernel must
110 be made and installed and booted with before a make world can
114 New jail syscall format requires recompilation of jail(8) with
115 fresh headers installed (or a make world will do it for you).
118 Matt Dillon checked in many vm related things and sent a heads up
119 to -current urging caution and to report vm problems to him.
120 As of the 19th, no killer problems have been reported, but you
124 The new miibus has been added to the system. If you are using
125 the dm, rl, sf, sis, ste, tl, wb or xl drivers, you need to
126 add "controller miibus0" to your config file.
129 /var/cron/log has been moved to /var/log/cron to get all the
130 log files in one place.
133 tn3270 has been removed from the base system and added as a port.
136 User-visible TCP timers are now expressed in units of 1ms, instead
137 of 500ms, so if you've customized any timer values under
138 ``net.inet.tcp'', multiply them by 500 to preserve TCP's behavior.
141 RCS Id tags changed to FreeBSD. This will cause huge cvsup
145 On 28-May-1999 libreadline was upgraded from readline-2.2 to
146 readline-4.0. At that time the shared library major version
147 number was bumped from "3" to "4". It has been deemed that
148 the interface change between readline-2.2 and readline-4.0 was
149 not sufficient to warrant the version number bump.
151 Thus I have reverted it back to "3". You will need to perform
152 the below immediately before your next ``make world'':
154 ls -l libreadline.so.4
155 (if you have /usr/lib/libreadline.so.4)
156 mv libreadline.so.4 libreadline.so.3
158 ln -s libreadline.so.3 libreadline.so
161 Changes to the pccardd kernel interface require that you recompile
162 pccardd for new kernel.
165 The ipfw interface to the kernel has changed. You will need to
166 recompile ipfw programs for the new kernel.
169 The bpfilter device has been renamed to bpf. You will need to
170 change your config files in order to enable this in newer kernels.
173 src/contrib/sys/softupdates is moving to
174 src/sys/contrib/softupdates. Update your symbolic links/etc.
177 Major changes have been made to vinum and its interface. See
178 the man page (vinum(8)) for details. Look at the concat,
179 mirror and stripe commands, as well as the SIMPLIFIED
180 CONFIGURATION section.
183 Newsyslog.conf has had a minor, but potentially dangerous,
184 change to its username/group syntax. The old syntax was
185 user.group, while the new syntax is user:group.
188 Inetd wrapping default has changed. Please see the updated
189 man page for details.
192 Compaq Smart Raid driver committed as ida.
195 The second phase of syscons cleanup has happened. Some
196 functionality has been made optional. For details, see
197 http://www.freebsd.org/~yokota/sc_update-June.txt
198 Everyone will need to re-config(8) their kernels, but old
199 binaries will work with the new kernel.
202 IPFW uid/gid-based filtering support has been committed. This
203 breaks binary compatibility with previous copies of
204 ipfw(8). Any utilities using the ioctl()s of ipfw (especially
205 ipfw(8)) need to be recompiled with the newest headers
209 Inetd now wraps all stream-based services, including internals.
210 Syslog "severity" options are honoured. Installed syslog.conf
211 and hosts.allow should be checked.
214 Most of the problems with newbus have been corrected, but
215 it is still current and evolving.
217 libcam's ABI has changed. You must recompile the world and
218 any ports that use it.
221 Massive changes to SMP went into the tree that should speed
222 things up. However, if you experience problems with SMP
223 machines, you can back off to the PRE_SMP_VMSHARE tag in the
224 CVS repository (or run an MP kernel).
227 Pccardd and the pccard bus in general seem to be broken or
228 most people. Soren has patches to make it better for some,
229 but not all people. Work is underway to make it better for
233 new bus changes integrated into -current. Many problems were
234 initially reported, but most have been fixed. You'll need a
235 new config and to tweak your kernel config file the way that
236 GENERIC was tweaked. Keep a copy of your old kernel when
237 upgrading in case your new kernel doesn't work (and report the
238 breakage to current@freebsd.org).
240 As of 19990421 the remaining problems/quirks are
242 o sio no longer supports pnp nor pccard. This will be corrected,
243 but the new pccard code needs to be completed.
244 o Some of the sound drivers broke for some people. It seems
245 inconsistant as to who/what/when/where things broke.
246 o Duplicate device entries in your config do not work. Previously
247 they were silently ignored. psm0 seems to be the most common
248 duplicate choice, although some reports have come in from people
249 that wired their scsi disk entries.
250 o You must move the keyboard and mouse attachments from the
251 isa bus to the atkbdc bus. See GENERIC for details.
252 o Machines with multiple host-pci bridges (Intel 450NX) will not
253 probe the second pci bus.
254 o Some probe ordering may have changed, so device naming may change
255 with the new kernel. If you have multiple devices, please double
256 check to make sure they didn't move. This is especially true
257 for cards on different buses.
258 o The bus attachment for vga0 is always isa0 and never pci0 when
259 it is in fact a pci card. It is safe to ignore this.
260 o The format of the boot messages has changed (and is not
261 guaranteed to be constant for a while) so you may see this
262 in some shell scripts that diff dmesg from day to day as well
263 as scripts that parse dmesg output.
266 cc -aout sometimes has problems compiling with -g, remove -g
267 from those compilation units affected until this is corrected.
269 cc -aout has problems with producing some threaded libraries,
270 so make world -DWANT_AOUT is not functional at this time.
272 Since make world for a.out isn't functional, you cannot do
273 make aout-to-elf from a pre-egcs a.out system. To work around
274 this problem, make aout-to-elf using 3.1-stable first (or a
275 pre egcs -current) and then a simple make world will take you
276 the rest of the way with a -current source base.
279 Make -j works again for make world. As always, use it with
280 care, and be sure to try a make world w/o -j before reporting
281 problems (that is, know if the problem exists w/o -j before
282 reporting the problem with -j).
285 Note cc -aout, which had been broken since the conversion to
286 egcs, now supposedly works. If you have rebuilt things like
287 XFree86 a.out libraries, you should rebuild them again or
288 progams that use them, including netscape, will fail to work.
291 NOTE: New c++ compiler cannot be used with c++ binaries from
292 the old compiler and vice versa.
295 In recent days egcs has been imported into the tree. A number
296 of problems have been discussed in -current. Here is a highlight
297 of a few of the more common ones. With the exception of make
298 -j n, they have been claimed to have been fixed.
300 c++ is broken after make world: This is correct. Because we
301 changed compilers two make worlds are necessary to get C++
302 working again. The code generated by the old compiler and new
303 compiler are not compatible, so things wind up being
306 cpp is broken in make world: There was a window where cpp
307 would be built incorrectly. The fix for this is
308 cd src/gnu/usr.bin/cc
312 and this should correct your problems. See the -current
313 archives for a version of this that does moer cleaning.
315 Make -j n doesn't work. Work contiunes to make this work,
316 I've seen no reports of success as of April 7th.
319 Previously, one would define "NOAOUT" to keep from building
320 the legacy a.out bits. Now one would define "WANT_AOUT" to
324 The name of the old wd.c and atapi.c based CDROM driver has
325 been changed back to wcd. So update your config file to use
326 "device wcd" instead of "device acd".
329 For those of you using the VN device as a loadable module,
330 please be aware that the new VN device has been committed to
331 -4.x and cannot yet be used as a loadable module. This will
332 be fixed in the future.
335 New loader.rc mechanism. Please see src/sys/boot/README for
339 struct proc size changed. Recompile kernel and the
340 usual suspects. Make world if in doubt.
343 The nlpt driver has changed names back to be the lpt driver.
344 See ppbus(4) or http://www.freebsd.org/~nsouch/ppbus.html
345 for proper configuration details.
348 The 'lpt' driver is now obsolete. Replace it with the 'nlpt'
349 driver and 'ppbus' controller combination.
352 New devstat API requires recompilation of libdevstat, systat,
353 iostat, vmstat and rpc.rstatd. A new kernel is also required.
354 make world + building a kernel should do all of this. Any
355 ports that use devstat need to be recompiled as well.
358 Linux threads options has gone away (they are now standard in
359 the FreeBSD kernel). A recompile of all libkvm using programs
360 is in order (or better yet a make world).
363 On or about this date there was a small window when the boot
364 blocks had some minor problems which seemed to force one to
365 edit /etc/fstab. This has been corrected, if you are seeing this
366 problem, please rebuild and reinstall your boot blocks.
369 Vinum has changed. The "vinum read" command has changed. For
372 http://www.freebsd.org/cgi/getmsg.cgi?fetch=800363+0+current/freebsd-current
376 Matt Dillon committed a boatload of VM changes, for
377 information please see
379 http://www.freebsd.org/cgi/getmsg.cgi?fetch=886676+0+current/freebsd-current
381 http://www.freebsd.org/cgi/getmsg.cgi?fetch=827400+0+current/freebsd-current
383 for details. These changes will likely not impact anybody,
384 but large chagnes to the VM need at least a heads up.
387 Stable branch created. You might want to consider using this
388 branch. It is tagged with RELENG_3.
391 More work on the syscons driver has been committed. Since
392 files moved around, you will need to reconfigure your kernel,
393 and make clean; make depend before rebuilding the kernel. No
394 config file changes are needed.
397 New keyboard and video card drivers are introduced as the first
398 stage of console driver reorganization. You are required to
399 update the kernel configuration file and rebuild the kernel.
400 kbdcontrol, vidcontrol, and screen savers also need recompilation.
401 The instruction can be found in
403 http://www.freebsd.org/~yokota/sc_update.txt
405 It has notes on splash screen too.
408 Robert Nordier was kind enough to make this page to enable people to
409 install the new bootblocks:
411 http://www.freebsd.org/~rnordier/boot.txt
413 When updating to ELF, make sure that you have updated your
414 /etc/rc files which have different ldconfig invocations for
415 elf and aout. Otherwise things like X will stop working with
416 messages about being unable to find library files. The
417 mergemaster utility in ports/sysutils/mergemaster helps to
418 keep critical files like this in sync, and its use is
422 Information about ELF day (see 19981230) can be found in
424 http://www.freebsd.org/~peter/elfday.html
426 about the upcoming change, its motivations and instructions
427 for doing the upgrade.
430 You should install new bootblocks now. The ELF kernel will
431 become default soon. In addition, you'll need to upgrade
432 your userland programs to ELF before then as well. Use
433 make aout-to-elf to upgrade your userland programs (old
434 a.out programs in, for example, /usr/local/bin will
435 continue to work, even after the upgrade). See src/Makefile
439 The old wcd driver has been deleted from the kernel. The
440 driver that replaces it is named acd. You'll need to change
441 this in your configuration files.
443 Failure to do this will result in "ATAPI CD-ROMs not
444 configured" at boot time.
446 The floppy tape driver (ft) has been removed from the kernel,
447 with no replacement driver.
450 New groups from 19981201 commented out of mtree, so they
451 aren't strictly needed, but still a good idea to have.
454 New user/group added: bind. From src/etc/master.passwd and
456 % grep <newstuff> /usr/src/etc/group
458 % grep <newstuff> /usr/src/etc/master.passwd
459 tty:*:4:65533::0:0:Tty Sandbox:/:/sbin/nologin
460 kmem:*:5:65533::0:0:KMem Sandbox:/:/sbin/nologin
461 bind:*:53:53::0:0:Bind Sandbox:/:/sbin/nologin
464 PAM integrated into the tree. Requires new /etc/pam.conf file
465 to silence warnings from authentication programs (login, etc).
466 See src/etc/pam.conf for a sample.
468 This file contains a list, in reverse chronologocal order, of major
469 breakages in tracking -current. Not all things will be listed here,
470 and it only starts on November 18, 1998. If you have an earlier
471 version of FreeBSD, you are on your own to get to November 18, 1998.
473 Please filter your entries through Warner (imp@village.org) so that
474 the style, formatting, etc of this file can be maintained.
