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 GNU texinfo upgraded to 4.0. It is recommended that you use
8 make buidlworld to update.
11 CAM_VERSION has been increased. Recompile all programs that
12 depend on it (tosha, camcontrol, etc) when moving to kernels
16 pccard ioctls changed with a commit to have the kernel tell
17 pccardd which device it created, rather than having pccardd
18 dictate it to the kernel. Recompile kernel and
19 pccardd/pccardc together. pccardd/pccardc rely on a kernel
20 Makefile that must be installed prior to building them. Make
21 world will automatically take care of this issue, but you need
22 to know if you are building by hand.
25 Your kernel config files need to be changed to s/controller/device/
26 in them. You will need a new version of config to do this.
29 chown & chgrp moved again
31 This is a heads up to let you know that you need to
32 rm -f /sbin/chown /bin/chgrp
33 after your next `make world'. Additionally you need to install
34 a new /dev/MAKEDEV (mergemaster(8) will assist you in this).
37 SHA-1 password support gone
39 As warned yesterday, I've just removed the ability for
40 libcrypt to understand SHA-1 passwords. This was present but
41 undocumented in the tree for the past few months and was
42 removed so it can be reimplemented properly as part of a
43 revamped libcrypt at a later date. Anyone who was actually
44 making use of the feature will have to update their passwords
45 back to MD5 before they reinstall the library.
48 ioctl numbers changed for dvdio ioctls. You will need to recompile
49 anything that uses them. wormcontrol has been deprecated in
53 Building linux and svr4 compatibility into the kernel now
54 requires /usr/bin/genassym. Go to /usr/src/usr.bin/genassym,
55 do "make obj ; make clean depend all install" before building
59 sendmail.cf has moved from /etc/sendmail.cf to
60 /etc/mail/sendmail.cf. You may need to adjust /etc/rc.conf
61 and /etc/rc to cope as well as moving sendmail.cf.
64 ntp 4.0.98 has replaced the ancient xntpd. The daemon name
65 changed from xntpd to ntpd, so you may need to update your
66 /etc/rc.conf file. The ntp.conf files are compatible with the
67 old release, unless you are using a local reference clock.
68 Details about ntp4 can be found at http://www.ntp.org/.
70 xntpd will be cvs removed from the repo in about a week.
73 Soren updated the ata driver. Please update to at least this
74 version before submitting bug reports.
77 The ata driver has become the primary ata/ide/atapi driver in
78 the kernel. The wd driver is obsolete. You should upgrade your
79 machine to the new ata driver. You will need to follow the
80 directions for updating the devices in the 19991205 entry. You
81 will need to update all occurances of wd to ad in your config files
82 (/etc/rc.conf, /etc/fstab, etc). A compatibility device exists
83 for wd for the time being, but once you have determined that
84 ata is working for you, transition to the new ad devices.
87 Block devices are going away. You will need to update your /dev
88 tree with a fresh copy of MAKEDEV for things to always work in
89 the future. fsck is unable to cope with dirty file systems
90 after this change, so it may work for you or it may not.
92 MAKEDEV should be copied from src/etc/MAKEDEV to /dev before
93 starting the following:
95 For N in the list of disks
97 for M in the list of slices
98 MAKEDEV NsMa # eg ad0s1a
100 *** All uses of block devices must be converted to char devices.
101 *** Likely the only thing impacted is dumpdev in /etc/rc.conf
104 The dc interface has replaced al, ax, dm, pn and mx. The former
108 Support for the old 'sd' device names has been removed in
109 favor of 'da'. Please update your /etc/fstab, /etc/rc.conf
110 and any other places you might have sd names cached.
111 Generally these changes are as simple as s=/dev/sd=/dev/da=g,
112 but be careful to make sure that things are really that
113 simple. You may also need to create /dev entries for the da
116 MAKEDEV should be copied from src/etc/MAKEDEV to /dev before
117 starting the following:
119 For N in the list of da disks on your system
121 for M in the list of slices
124 BAD144 support has been removed. Cope or replace the hardware.
127 ALPHA users take note. All klds will need to be recompiled for
128 kernels build after this date. It is a good time to update since
129 pal.s will be going away soon.
132 MFS_ROOT and MFS_ROOT_SIZE are gone, replaced by MD_ROOT and
133 MD_ROOT_SIZE options in the md driver. md driver now deals with
134 the hacks. You should add md driver to kerneles that have
135 MFS_ROOT, et al. See GENERIC or LINT for details.
138 The ep changed a while ago and can no longer be used with hard
139 wired addresses in the config file.
142 The bridge drivers for sound cards have been committed. Please
143 see LINT for instructions for your card, if it still works at
147 Gcc 2.95.2 is now the default compiler.
150 /etc/radius.conf file format has changed.The format change is
151 as follows. Each server line in the file should now begin
152 with a new field containing either "auth" for RADIUS
153 authentication, or "acct" for RADIUS accounting. Formerly
154 only authentication was supported. If the first field isn't
155 "auth" or "acct" then the code assumes that "auth" is
156 intended. (That's the compatibility hack.)
159 PCCARD has been updated to attach pcic to the isa bus. Therefore
160 you will need to modify kernel config files that have pcic/card
162 controller pcic0 at isa?
163 controller pcic1 at isa?
167 The sigset_t datatype has been changed from an integral type
168 to a compound type and can hold 128 signals. Syscalls directly
169 or indirectly using the new sigset_t have been added as to
170 maintain compatibility with existing binaries. A new kernel must
171 be made and installed and booted with before a make world can
175 New jail syscall format requires recompilation of jail(8) with
176 fresh headers installed (or a make world will do it for you).
179 Matt Dillon checked in many vm related things and sent a heads up
180 to -current urging caution and to report vm problems to him.
181 As of the 19th, no killer problems have been reported, but you
185 The new miibus has been added to the system. If you are using
186 the dm, rl, sf, sis, ste, tl, wb or xl drivers, you need to
187 add "controller miibus0" to your config file.
190 /var/cron/log has been moved to /var/log/cron to get all the
191 log files in one place.
194 tn3270 has been removed from the base system and added as a port.
197 User-visible TCP timers are now expressed in units of 1ms, instead
198 of 500ms, so if you've customized any timer values under
199 ``net.inet.tcp'', multiply them by 500 to preserve TCP's behavior.
202 RCS Id tags changed to FreeBSD. This will cause huge cvsup
206 On 28-May-1999 libreadline was upgraded from readline-2.2 to
207 readline-4.0. At that time the shared library major version
208 number was bumped from "3" to "4". It has been deemed that
209 the interface change between readline-2.2 and readline-4.0 was
210 not sufficient to warrant the version number bump.
212 Thus I have reverted it back to "3". You will need to perform
213 the below immediately before your next ``make world'':
215 ls -l libreadline.so.4
216 (if you have /usr/lib/libreadline.so.4)
217 mv libreadline.so.4 libreadline.so.3
219 ln -s libreadline.so.3 libreadline.so
222 Changes to the pccardd kernel interface require that you recompile
223 pccardd for new kernel.
226 The ipfw interface to the kernel has changed. You will need to
227 recompile ipfw programs for the new kernel.
230 The bpfilter device has been renamed to bpf. You will need to
231 change your config files in order to enable this in newer kernels.
234 src/contrib/sys/softupdates is moving to
235 src/sys/contrib/softupdates. Update your symbolic links/etc.
238 Major changes have been made to vinum and its interface. See
239 the man page (vinum(8)) for details. Look at the concat,
240 mirror and stripe commands, as well as the SIMPLIFIED
241 CONFIGURATION section.
244 Newsyslog.conf has had a minor, but potentially dangerous,
245 change to its username/group syntax. The old syntax was
246 user.group, while the new syntax is user:group.
249 Inetd wrapping default has changed. Please see the updated
250 man page for details.
253 Compaq Smart Raid driver committed as ida.
256 The second phase of syscons cleanup has happened. Some
257 functionality has been made optional. For details, see
258 http://www.freebsd.org/~yokota/sc_update-June.txt
259 Everyone will need to re-config(8) their kernels, but old
260 binaries will work with the new kernel.
263 IPFW uid/gid-based filtering support has been committed. This
264 breaks binary compatibility with previous copies of
265 ipfw(8). Any utilities using the ioctl()s of ipfw (especially
266 ipfw(8)) need to be recompiled with the newest headers
270 Inetd now wraps all stream-based services, including internals.
271 Syslog "severity" options are honoured. Installed syslog.conf
272 and hosts.allow should be checked.
275 Most of the problems with newbus have been corrected, but
276 it is still current and evolving.
278 libcam's ABI has changed. You must recompile the world and
279 any ports that use it.
282 Massive changes to SMP went into the tree that should speed
283 things up. However, if you experience problems with SMP
284 machines, you can back off to the PRE_SMP_VMSHARE tag in the
285 CVS repository (or run an MP kernel).
288 Pccardd and the pccard bus in general seem to be broken or
289 most people. Soren has patches to make it better for some,
290 but not all people. Work is underway to make it better for
294 new bus changes integrated into -current. Many problems were
295 initially reported, but most have been fixed. You'll need a
296 new config and to tweak your kernel config file the way that
297 GENERIC was tweaked. Keep a copy of your old kernel when
298 upgrading in case your new kernel doesn't work (and report the
299 breakage to current@freebsd.org).
301 As of 19990421 the remaining problems/quirks are
303 o sio no longer supports pnp nor pccard. This will be corrected,
304 but the new pccard code needs to be completed.
305 o Some of the sound drivers broke for some people. It seems
306 inconsistant as to who/what/when/where things broke.
307 o Duplicate device entries in your config do not work. Previously
308 they were silently ignored. psm0 seems to be the most common
309 duplicate choice, although some reports have come in from people
310 that wired their scsi disk entries.
311 o You must move the keyboard and mouse attachments from the
312 isa bus to the atkbdc bus. See GENERIC for details.
313 o Machines with multiple host-pci bridges (Intel 450NX) will not
314 probe the second pci bus.
315 o Some probe ordering may have changed, so device naming may change
316 with the new kernel. If you have multiple devices, please double
317 check to make sure they didn't move. This is especially true
318 for cards on different buses.
319 o The bus attachment for vga0 is always isa0 and never pci0 when
320 it is in fact a pci card. It is safe to ignore this.
321 o The format of the boot messages has changed (and is not
322 guaranteed to be constant for a while) so you may see this
323 in some shell scripts that diff dmesg from day to day as well
324 as scripts that parse dmesg output.
327 cc -aout sometimes has problems compiling with -g, remove -g
328 from those compilation units affected until this is corrected.
330 cc -aout has problems with producing some threaded libraries,
331 so make world -DWANT_AOUT is not functional at this time.
333 Since make world for a.out isn't functional, you cannot do
334 make aout-to-elf from a pre-egcs a.out system. To work around
335 this problem, make aout-to-elf using 3.1-stable first (or a
336 pre egcs -current) and then a simple make world will take you
337 the rest of the way with a -current source base.
340 Make -j works again for make world. As always, use it with
341 care, and be sure to try a make world w/o -j before reporting
342 problems (that is, know if the problem exists w/o -j before
343 reporting the problem with -j).
346 Note cc -aout, which had been broken since the conversion to
347 egcs, now supposedly works. If you have rebuilt things like
348 XFree86 a.out libraries, you should rebuild them again or
349 progams that use them, including netscape, will fail to work.
352 NOTE: New c++ compiler cannot be used with c++ binaries from
353 the old compiler and vice versa.
356 In recent days egcs has been imported into the tree. A number
357 of problems have been discussed in -current. Here is a highlight
358 of a few of the more common ones. With the exception of make
359 -j n, they have been claimed to have been fixed.
361 c++ is broken after make world: This is correct. Because we
362 changed compilers two make worlds are necessary to get C++
363 working again. The code generated by the old compiler and new
364 compiler are not compatible, so things wind up being
367 cpp is broken in make world: There was a window where cpp
368 would be built incorrectly. The fix for this is
369 cd src/gnu/usr.bin/cc
373 and this should correct your problems. See the -current
374 archives for a version of this that does moer cleaning.
376 Make -j n doesn't work. Work contiunes to make this work,
377 I've seen no reports of success as of April 7th.
380 Previously, one would define "NOAOUT" to keep from building
381 the legacy a.out bits. Now one would define "WANT_AOUT" to
385 The name of the old wd.c and atapi.c based CDROM driver has
386 been changed back to wcd. So update your config file to use
387 "device wcd" instead of "device acd".
390 For those of you using the VN device as a loadable module,
391 please be aware that the new VN device has been committed to
392 -4.x and cannot yet be used as a loadable module. This will
393 be fixed in the future.
396 New loader.rc mechanism. Please see src/sys/boot/README for
400 struct proc size changed. Recompile kernel and the
401 usual suspects. Make world if in doubt.
404 The nlpt driver has changed names back to be the lpt driver.
405 See ppbus(4) or http://www.freebsd.org/~nsouch/ppbus.html
406 for proper configuration details.
409 The 'lpt' driver is now obsolete. Replace it with the 'nlpt'
410 driver and 'ppbus' controller combination.
413 New devstat API requires recompilation of libdevstat, systat,
414 iostat, vmstat and rpc.rstatd. A new kernel is also required.
415 make world + building a kernel should do all of this. Any
416 ports that use devstat need to be recompiled as well.
419 Linux threads options has gone away (they are now standard in
420 the FreeBSD kernel). A recompile of all libkvm using programs
421 is in order (or better yet a make world).
424 On or about this date there was a small window when the boot
425 blocks had some minor problems which seemed to force one to
426 edit /etc/fstab. This has been corrected, if you are seeing this
427 problem, please rebuild and reinstall your boot blocks.
430 Vinum has changed. The "vinum read" command has changed. For
433 http://www.freebsd.org/cgi/getmsg.cgi?fetch=800363+0+current/freebsd-current
437 Matt Dillon committed a boatload of VM changes, for
438 information please see
440 http://www.freebsd.org/cgi/getmsg.cgi?fetch=886676+0+current/freebsd-current
442 http://www.freebsd.org/cgi/getmsg.cgi?fetch=827400+0+current/freebsd-current
444 for details. These changes will likely not impact anybody,
445 but large chagnes to the VM need at least a heads up.
448 Stable branch created. You might want to consider using this
449 branch. It is tagged with RELENG_3.
452 More work on the syscons driver has been committed. Since
453 files moved around, you will need to reconfigure your kernel,
454 and make clean; make depend before rebuilding the kernel. No
455 config file changes are needed.
458 New keyboard and video card drivers are introduced as the first
459 stage of console driver reorganization. You are required to
460 update the kernel configuration file and rebuild the kernel.
461 kbdcontrol, vidcontrol, and screen savers also need recompilation.
462 The instruction can be found in
464 http://www.freebsd.org/~yokota/sc_update.txt
466 It has notes on splash screen too.
469 Robert Nordier was kind enough to make this page to enable people to
470 install the new bootblocks:
472 http://www.freebsd.org/~rnordier/boot.txt
474 When updating to ELF, make sure that you have updated your
475 /etc/rc files which have different ldconfig invocations for
476 elf and aout. Otherwise things like X will stop working with
477 messages about being unable to find library files. The
478 mergemaster utility in ports/sysutils/mergemaster helps to
479 keep critical files like this in sync, and its use is
483 Information about ELF day (see 19981230) can be found in
485 http://www.freebsd.org/~peter/elfday.html
487 about the upcoming change, its motivations and instructions
488 for doing the upgrade.
491 You should install new bootblocks now. The ELF kernel will
492 become default soon. In addition, you'll need to upgrade
493 your userland programs to ELF before then as well. Use
494 make aout-to-elf to upgrade your userland programs (old
495 a.out programs in, for example, /usr/local/bin will
496 continue to work, even after the upgrade). See src/Makefile
500 The old wcd driver has been deleted from the kernel. The
501 driver that replaces it is named acd. You'll need to change
502 this in your configuration files.
504 Failure to do this will result in "ATAPI CD-ROMs not
505 configured" at boot time.
507 The floppy tape driver (ft) has been removed from the kernel,
508 with no replacement driver.
511 New groups from 19981201 commented out of mtree, so they
512 aren't strictly needed, but still a good idea to have.
515 New user/group added: bind. From src/etc/master.passwd and
517 % grep <newstuff> /usr/src/etc/group
519 % grep <newstuff> /usr/src/etc/master.passwd
520 tty:*:4:65533::0:0:Tty Sandbox:/:/sbin/nologin
521 kmem:*:5:65533::0:0:KMem Sandbox:/:/sbin/nologin
522 bind:*:53:53::0:0:Bind Sandbox:/:/sbin/nologin
525 PAM integrated into the tree. Requires new /etc/pam.conf file
526 to silence warnings from authentication programs (login, etc).
527 See src/etc/pam.conf for a sample.
529 This file contains a list, in reverse chronologocal order, of major
530 breakages in tracking -current. Not all things will be listed here,
531 and it only starts on November 18, 1998. If you have an earlier
532 version of FreeBSD, you are on your own to get to November 18, 1998.
534 Please filter your entries through Warner (imp@village.org) so that
535 the style, formatting, etc of this file can be maintained.
