4 directly to him. See end of file for further details.
7 chown & chgrp moved again
9 This is a heads up to let you know that you need to
10 rm -f /sbin/chown /bin/chgrp
11 after your next `make world'. Additionally you need to install
12 a new /dev/MAKEDEV (mergmaster(8) will assist you in this).
15 SHA-1 password support gone
17 As warned yesterday, I've just removed the ability for
18 libcrypt to understand SHA-1 passwords. This was present but
19 undocumented in the tree for the past few months and was
20 removed so it can be reimplemented properly as part of a
21 revamped libcrypt at a later date. Anyone who was actually
22 making use of the feature will have to update their passwords
23 back to MD5 before they reinstall the library.
26 ioctl numbers changed for dvdio ioctls. You will need to recompile
27 anything that uses them. wormcontrol has been depreicated in
31 Building linux and svr4 compatibility into the kernel now
32 requires /usr/bin/genassym. Go to /usr/src/usr.bin/genassym,
33 do "make obj ; make clean depend all install" before building
37 sendmail.cf has moved from /etc/sendmail.cf to
38 /etc/mail/sendmail.cf. You may need to adjust /etc/rc.conf
39 and /etc/rc to cope as well as moving sendmail.cf.
42 ntp 4.0.98 has replaced the ancient xntpd. The daemon name
43 changed from xntpd to ntpd, so you may need to update your
44 /etc/rc.conf file. The ntp.conf files are compatible with the
45 old release, unless you are using a local reference clock.
46 Details about ntp4 can be found at http://www.ntp.org/.
48 xntpd will be cvs removed from the repo in about a week.
51 Soren updated the ata driver. Please update to at least this
52 version before submitting bug reports.
55 The ata driver has become the primary ata/ide/atapi driver in
56 the kernel. The wd driver is obsolete. You should upgrade your
57 machine to the new ata driver. You will need to follow the
58 directions for updating the devices in the 19991205 entry. You
59 will need to update all occurances of wd to ad in your config files
60 (/etc/rc.conf, /etc/fstab, etc). A compatibility device exists
61 for wd for the time being, but once you have determined that
62 ata is working for you, transition to the new ad devices.
65 Block devices are going away. You will need to update your /dev
66 tree with a fresh copy of MAKEDEV for things to always work in
67 the future. fsck is unable to cope with dirty file systems
68 after this change, so it may work for you or it may not.
70 MAKEDEV should be copied from src/etc/MAKEDEV to /dev before
71 starting the following:
73 For N in the list of disks
75 for M in the list of slices
76 MAKEDEV NsMa # eg ad0s1a
78 *** All uses of block devices must be converted to char devices.
79 *** Likely the only thing impacted is dumpdev in /etc/rc.conf
82 The dc interface has replaced al, ax, dm, pn and mx. The former
86 Support for the old 'sd' device names has been removed in
87 favor of 'da'. Please update your /etc/fstab, /etc/rc.conf
88 and any other places you might have sd names cached.
89 Generally these changes are as simple as s=/dev/sd=/dev/da=g,
90 but be careful to make sure that things are really that
91 simple. You may also need to create /dev entries for the da
94 MAKEDEV should be copied from src/etc/MAKEDEV to /dev before
95 starting the following:
97 For N in the list of da disks on your system
99 for M in the list of slices
102 BAD144 support has been removed. Cope or replace the hardware.
105 ALPHA users take note. All klds will need to be recompiled for
106 kernels build after this date. It is a good time to update since
107 pal.s will be going away soon.
110 MFS_ROOT and MFS_ROOT_SIZE are gone, replaced by MD_ROOT and
111 MD_ROOT_SIZE options in the md driver. md driver now deals with
112 the hacks. You should add md driver to kerneles that have
113 MFS_ROOT, et al. See GENERIC or LINT for details.
116 The ep changed a while ago and can no longer be used with hard
117 wired addresses in the config file.
120 The bridge drivers for sound cards have been committed. Please
121 see LINT for instructions for your card, if it still works at
125 Gcc 2.95.2 is now the default compiler.
128 /etc/radius.conf file format has changed.The format change is
129 as follows. Each server line in the file should now begin
130 with a new field containing either "auth" for RADIUS
131 authentication, or "acct" for RADIUS accounting. Formerly
132 only authentication was supported. If the first field isn't
133 "auth" or "acct" then the code assumes that "auth" is
134 intended. (That's the compatibility hack.)
137 PCCARD has been updated to attach pcic to the isa bus. Therefore
138 you will need to modify kernel config files that have pcic/card
140 controller pcic0 at isa?
141 controller pcic1 at isa?
145 The sigset_t datatype has been changed from an integral type
146 to a compound type and can hold 128 signals. Syscalls directly
147 or indirectly using the new sigset_t have been added as to
148 maintain compatibility with existing binaries. A new kernel must
149 be made and installed and booted with before a make world can
153 New jail syscall format requires recompilation of jail(8) with
154 fresh headers installed (or a make world will do it for you).
157 Matt Dillon checked in many vm related things and sent a heads up
158 to -current urging caution and to report vm problems to him.
159 As of the 19th, no killer problems have been reported, but you
163 The new miibus has been added to the system. If you are using
164 the dm, rl, sf, sis, ste, tl, wb or xl drivers, you need to
165 add "controller miibus0" to your config file.
168 /var/cron/log has been moved to /var/log/cron to get all the
169 log files in one place.
172 tn3270 has been removed from the base system and added as a port.
175 User-visible TCP timers are now expressed in units of 1ms, instead
176 of 500ms, so if you've customized any timer values under
177 ``net.inet.tcp'', multiply them by 500 to preserve TCP's behavior.
180 RCS Id tags changed to FreeBSD. This will cause huge cvsup
184 On 28-May-1999 libreadline was upgraded from readline-2.2 to
185 readline-4.0. At that time the shared library major version
186 number was bumped from "3" to "4". It has been deemed that
187 the interface change between readline-2.2 and readline-4.0 was
188 not sufficient to warrant the version number bump.
190 Thus I have reverted it back to "3". You will need to perform
191 the below immediately before your next ``make world'':
193 ls -l libreadline.so.4
194 (if you have /usr/lib/libreadline.so.4)
195 mv libreadline.so.4 libreadline.so.3
197 ln -s libreadline.so.3 libreadline.so
200 Changes to the pccardd kernel interface require that you recompile
201 pccardd for new kernel.
204 The ipfw interface to the kernel has changed. You will need to
205 recompile ipfw programs for the new kernel.
208 The bpfilter device has been renamed to bpf. You will need to
209 change your config files in order to enable this in newer kernels.
212 src/contrib/sys/softupdates is moving to
213 src/sys/contrib/softupdates. Update your symbolic links/etc.
216 Major changes have been made to vinum and its interface. See
217 the man page (vinum(8)) for details. Look at the concat,
218 mirror and stripe commands, as well as the SIMPLIFIED
219 CONFIGURATION section.
222 Newsyslog.conf has had a minor, but potentially dangerous,
223 change to its username/group syntax. The old syntax was
224 user.group, while the new syntax is user:group.
227 Inetd wrapping default has changed. Please see the updated
228 man page for details.
231 Compaq Smart Raid driver committed as ida.
234 The second phase of syscons cleanup has happened. Some
235 functionality has been made optional. For details, see
236 http://www.freebsd.org/~yokota/sc_update-June.txt
237 Everyone will need to re-config(8) their kernels, but old
238 binaries will work with the new kernel.
241 IPFW uid/gid-based filtering support has been committed. This
242 breaks binary compatibility with previous copies of
243 ipfw(8). Any utilities using the ioctl()s of ipfw (especially
244 ipfw(8)) need to be recompiled with the newest headers
248 Inetd now wraps all stream-based services, including internals.
249 Syslog "severity" options are honoured. Installed syslog.conf
250 and hosts.allow should be checked.
253 Most of the problems with newbus have been corrected, but
254 it is still current and evolving.
256 libcam's ABI has changed. You must recompile the world and
257 any ports that use it.
260 Massive changes to SMP went into the tree that should speed
261 things up. However, if you experience problems with SMP
262 machines, you can back off to the PRE_SMP_VMSHARE tag in the
263 CVS repository (or run an MP kernel).
266 Pccardd and the pccard bus in general seem to be broken or
267 most people. Soren has patches to make it better for some,
268 but not all people. Work is underway to make it better for
272 new bus changes integrated into -current. Many problems were
273 initially reported, but most have been fixed. You'll need a
274 new config and to tweak your kernel config file the way that
275 GENERIC was tweaked. Keep a copy of your old kernel when
276 upgrading in case your new kernel doesn't work (and report the
277 breakage to current@freebsd.org).
279 As of 19990421 the remaining problems/quirks are
281 o sio no longer supports pnp nor pccard. This will be corrected,
282 but the new pccard code needs to be completed.
283 o Some of the sound drivers broke for some people. It seems
284 inconsistant as to who/what/when/where things broke.
285 o Duplicate device entries in your config do not work. Previously
286 they were silently ignored. psm0 seems to be the most common
287 duplicate choice, although some reports have come in from people
288 that wired their scsi disk entries.
289 o You must move the keyboard and mouse attachments from the
290 isa bus to the atkbdc bus. See GENERIC for details.
291 o Machines with multiple host-pci bridges (Intel 450NX) will not
292 probe the second pci bus.
293 o Some probe ordering may have changed, so device naming may change
294 with the new kernel. If you have multiple devices, please double
295 check to make sure they didn't move. This is especially true
296 for cards on different buses.
297 o The bus attachment for vga0 is always isa0 and never pci0 when
298 it is in fact a pci card. It is safe to ignore this.
299 o The format of the boot messages has changed (and is not
300 guaranteed to be constant for a while) so you may see this
301 in some shell scripts that diff dmesg from day to day as well
302 as scripts that parse dmesg output.
305 cc -aout sometimes has problems compiling with -g, remove -g
306 from those compilation units affected until this is corrected.
308 cc -aout has problems with producing some threaded libraries,
309 so make world -DWANT_AOUT is not functional at this time.
311 Since make world for a.out isn't functional, you cannot do
312 make aout-to-elf from a pre-egcs a.out system. To work around
313 this problem, make aout-to-elf using 3.1-stable first (or a
314 pre egcs -current) and then a simple make world will take you
315 the rest of the way with a -current source base.
318 Make -j works again for make world. As always, use it with
319 care, and be sure to try a make world w/o -j before reporting
320 problems (that is, know if the problem exists w/o -j before
321 reporting the problem with -j).
324 Note cc -aout, which had been broken since the conversion to
325 egcs, now supposedly works. If you have rebuilt things like
326 XFree86 a.out libraries, you should rebuild them again or
327 progams that use them, including netscape, will fail to work.
330 NOTE: New c++ compiler cannot be used with c++ binaries from
331 the old compiler and vice versa.
334 In recent days egcs has been imported into the tree. A number
335 of problems have been discussed in -current. Here is a highlight
336 of a few of the more common ones. With the exception of make
337 -j n, they have been claimed to have been fixed.
339 c++ is broken after make world: This is correct. Because we
340 changed compilers two make worlds are necessary to get C++
341 working again. The code generated by the old compiler and new
342 compiler are not compatible, so things wind up being
345 cpp is broken in make world: There was a window where cpp
346 would be built incorrectly. The fix for this is
347 cd src/gnu/usr.bin/cc
351 and this should correct your problems. See the -current
352 archives for a version of this that does moer cleaning.
354 Make -j n doesn't work. Work contiunes to make this work,
355 I've seen no reports of success as of April 7th.
358 Previously, one would define "NOAOUT" to keep from building
359 the legacy a.out bits. Now one would define "WANT_AOUT" to
363 The name of the old wd.c and atapi.c based CDROM driver has
364 been changed back to wcd. So update your config file to use
365 "device wcd" instead of "device acd".
368 For those of you using the VN device as a loadable module,
369 please be aware that the new VN device has been committed to
370 -4.x and cannot yet be used as a loadable module. This will
371 be fixed in the future.
374 New loader.rc mechanism. Please see src/sys/boot/README for
378 struct proc size changed. Recompile kernel and the
379 usual suspects. Make world if in doubt.
382 The nlpt driver has changed names back to be the lpt driver.
383 See ppbus(4) or http://www.freebsd.org/~nsouch/ppbus.html
384 for proper configuration details.
387 The 'lpt' driver is now obsolete. Replace it with the 'nlpt'
388 driver and 'ppbus' controller combination.
391 New devstat API requires recompilation of libdevstat, systat,
392 iostat, vmstat and rpc.rstatd. A new kernel is also required.
393 make world + building a kernel should do all of this. Any
394 ports that use devstat need to be recompiled as well.
397 Linux threads options has gone away (they are now standard in
398 the FreeBSD kernel). A recompile of all libkvm using programs
399 is in order (or better yet a make world).
402 On or about this date there was a small window when the boot
403 blocks had some minor problems which seemed to force one to
404 edit /etc/fstab. This has been corrected, if you are seeing this
405 problem, please rebuild and reinstall your boot blocks.
408 Vinum has changed. The "vinum read" command has changed. For
411 http://www.freebsd.org/cgi/getmsg.cgi?fetch=800363+0+current/freebsd-current
415 Matt Dillon committed a boatload of VM changes, for
416 information please see
418 http://www.freebsd.org/cgi/getmsg.cgi?fetch=886676+0+current/freebsd-current
420 http://www.freebsd.org/cgi/getmsg.cgi?fetch=827400+0+current/freebsd-current
422 for details. These changes will likely not impact anybody,
423 but large chagnes to the VM need at least a heads up.
426 Stable branch created. You might want to consider using this
427 branch. It is tagged with RELENG_3.
430 More work on the syscons driver has been committed. Since
431 files moved around, you will need to reconfigure your kernel,
432 and make clean; make depend before rebuilding the kernel. No
433 config file changes are needed.
436 New keyboard and video card drivers are introduced as the first
437 stage of console driver reorganization. You are required to
438 update the kernel configuration file and rebuild the kernel.
439 kbdcontrol, vidcontrol, and screen savers also need recompilation.
440 The instruction can be found in
442 http://www.freebsd.org/~yokota/sc_update.txt
444 It has notes on splash screen too.
447 Robert Nordier was kind enough to make this page to enable people to
448 install the new bootblocks:
450 http://www.freebsd.org/~rnordier/boot.txt
452 When updating to ELF, make sure that you have updated your
453 /etc/rc files which have different ldconfig invocations for
454 elf and aout. Otherwise things like X will stop working with
455 messages about being unable to find library files. The
456 mergemaster utility in ports/sysutils/mergemaster helps to
457 keep critical files like this in sync, and its use is
461 Information about ELF day (see 19981230) can be found in
463 http://www.freebsd.org/~peter/elfday.html
465 about the upcoming change, its motivations and instructions
466 for doing the upgrade.
469 You should install new bootblocks now. The ELF kernel will
470 become default soon. In addition, you'll need to upgrade
471 your userland programs to ELF before then as well. Use
472 make aout-to-elf to upgrade your userland programs (old
473 a.out programs in, for example, /usr/local/bin will
474 continue to work, even after the upgrade). See src/Makefile
478 The old wcd driver has been deleted from the kernel. The
479 driver that replaces it is named acd. You'll need to change
480 this in your configuration files.
482 Failure to do this will result in "ATAPI CD-ROMs not
483 configured" at boot time.
485 The floppy tape driver (ft) has been removed from the kernel,
486 with no replacement driver.
489 New groups from 19981201 commented out of mtree, so they
490 aren't strictly needed, but still a good idea to have.
493 New user/group added: bind. From src/etc/master.passwd and
495 % grep <newstuff> /usr/src/etc/group
497 % grep <newstuff> /usr/src/etc/master.passwd
498 tty:*:4:65533::0:0:Tty Sandbox:/:/sbin/nologin
499 kmem:*:5:65533::0:0:KMem Sandbox:/:/sbin/nologin
500 bind:*:53:53::0:0:Bind Sandbox:/:/sbin/nologin
503 PAM integrated into the tree. Requires new /etc/pam.conf file
504 to silence warnings from authentication programs (login, etc).
505 See src/etc/pam.conf for a sample.
507 This file contains a list, in reverse chronologocal order, of major
508 breakages in tracking -current. Not all things will be listed here,
509 and it only starts on November 18, 1998. If you have an earlier
510 version of FreeBSD, you are on your own to get to November 18, 1998.
512 Please filter your entries through Warner (imp@village.org) so that
