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 Soren updated the ata driver. Please update to at least this
8 version before submitting bug reports.
11 The ata driver has become the primary ata/ide/atapi driver in
12 the kernel. The wd driver is obsolete. You should upgrade your
13 machine to the new ata driver. You will need to follow the
14 directions for updating the devices in the 19991205 entry. You
15 will need to update all occurances of wd to ad in your config files
16 (/etc/rc.conf, /etc/fstab, etc). A compatibility device exists
17 for wd for the time being, but once you have determined that
18 ata is working for you, transition to the new ad devices.
21 Block devices are going away. You will need to update your /dev
22 tree with a fresh copy of MAKEDEV for things to always work in
23 the future. fsck is unable to cope with dirty file systems
24 after this change, so it may work for you or it may not.
26 MAKEDEV should be copied from src/etc/MAKEDEV to /dev before
27 starting the following:
29 For N in the list of disks
31 for M in the list of slices
32 MAKEDEV NsMa # eg ad0s1a
34 *** All uses of block devices must be converted to char devices.
35 *** Likely the only thing impacted is dumpdev in /etc/rc.conf
38 The dc interface has replaced al, ax, dm, pn and mx. The former
42 Support for the old 'sd' device names has been removed in
43 favor of 'da'. Please update your /etc/fstab, /etc/rc.conf
44 and any other places you might have sd names cached.
45 Generally these changes are as simple as s=/dev/sd=/dev/da=g,
46 but be careful to make sure that things are really that
47 simple. You may also need to create /dev entries for the da
50 MAKEDEV should be copied from src/etc/MAKEDEV to /dev before
51 starting the following:
53 For N in the list of da disks on your system
55 for M in the list of slices
58 BAD144 support has been removed. Cope or replace the hardware.
61 ALPHA users take note. All klds will need to be recompiled for
62 kernels build after this date. It is a good time to update since
63 pal.s will be going away soon.
66 MFS_ROOT and MFS_ROOT_SIZE are gone, replaced by MD_ROOT and
67 MD_ROOT_SIZE options in the md driver. md driver now deals with
68 the hacks. You should add md driver to kerneles that have
69 MFS_ROOT, et al. See GENERIC or LINT for details.
72 The ep changed a while ago and can no longer be used with hard
73 wired addresses in the config file.
76 The bridge drivers for sound cards have been committed. Please
77 see LINT for instructions for your card, if it still works at
81 Gcc 2.95.2 is now the default compiler.
84 PCCARD has been updated to attach pcic to the isa bus. Therefore
85 you will need to modify kernel config files that have pcic/card
87 controller pcic0 at isa?
88 controller pcic1 at isa?
92 The sigset_t datatype has been changed from an integral type
93 to a compound type and can hold 128 signals. Syscalls directly
94 or indirectly using the new sigset_t have been added as to
95 maintain compatibility with existing binaries. A new kernel must
96 be made and installed and booted with before a make world can
100 New jail syscall format requires recompilation of jail(8) with
101 fresh headers installed (or a make world will do it for you).
104 Matt Dillon checked in many vm related things and sent a heads up
105 to -current urging caution and to report vm problems to him.
106 As of the 19th, no killer problems have been reported, but you
110 The new miibus has been added to the system. If you are using
111 the dm, rl, sf, sis, ste, tl, wb or xl drivers, you need to
112 add "controller miibus0" to your config file.
115 /var/cron/log has been moved to /var/log/cron to get all the
116 log files in one place.
119 tn3270 has been removed from the base system and added as a port.
122 User-visible TCP timers are now expressed in units of 1ms, instead
123 of 500ms, so if you've customized any timer values under
124 ``net.inet.tcp'', multiply them by 500 to preserve TCP's behavior.
127 RCS Id tags changed to FreeBSD. This will cause huge cvsup
131 On 28-May-1999 libreadline was upgraded from readline-2.2 to
132 readline-4.0. At that time the shared library major version
133 number was bumped from "3" to "4". It has been deemed that
134 the interface change between readline-2.2 and readline-4.0 was
135 not sufficient to warrant the version number bump.
137 Thus I have reverted it back to "3". You will need to perform
138 the below immediately before your next ``make world'':
140 ls -l libreadline.so.4
141 (if you have /usr/lib/libreadline.so.4)
142 mv libreadline.so.4 libreadline.so.3
144 ln -s libreadline.so.3 libreadline.so
147 Changes to the pccardd kernel interface require that you recompile
148 pccardd for new kernel.
151 The ipfw interface to the kernel has changed. You will need to
152 recompile ipfw programs for the new kernel.
155 The bpfilter device has been renamed to bpf. You will need to
156 change your config files in order to enable this in newer kernels.
159 src/contrib/sys/softupdates is moving to
160 src/sys/contrib/softupdates. Update your symbolic links/etc.
163 Major changes have been made to vinum and its interface. See
164 the man page (vinum(8)) for details. Look at the concat,
165 mirror and stripe commands, as well as the SIMPLIFIED
166 CONFIGURATION section.
169 Newsyslog.conf has had a minor, but potentially dangerous,
170 change to its username/group syntax. The old syntax was
171 user.group, while the new syntax is user:group.
174 Inetd wrapping default has changed. Please see the updated
175 man page for details.
178 Compaq Smart Raid driver committed as ida.
181 The second phase of syscons cleanup has happened. Some
182 functionality has been made optional. For details, see
183 http://www.freebsd.org/~yokota/sc_update-June.txt
184 Everyone will need to re-config(8) their kernels, but old
185 binaries will work with the new kernel.
188 IPFW uid/gid-based filtering support has been committed. This
189 breaks binary compatibility with previous copies of
190 ipfw(8). Any utilities using the ioctl()s of ipfw (especially
191 ipfw(8)) need to be recompiled with the newest headers
195 Inetd now wraps all stream-based services, including internals.
196 Syslog "severity" options are honoured. Installed syslog.conf
197 and hosts.allow should be checked.
200 Most of the problems with newbus have been corrected, but
201 it is still current and evolving.
203 libcam's ABI has changed. You must recompile the world and
204 any ports that use it.
207 Massive changes to SMP went into the tree that should speed
208 things up. However, if you experience problems with SMP
209 machines, you can back off to the PRE_SMP_VMSHARE tag in the
210 CVS repository (or run an MP kernel).
213 Pccardd and the pccard bus in general seem to be broken or
214 most people. Soren has patches to make it better for some,
215 but not all people. Work is underway to make it better for
219 new bus changes integrated into -current. Many problems were
220 initially reported, but most have been fixed. You'll need a
221 new config and to tweak your kernel config file the way that
222 GENERIC was tweaked. Keep a copy of your old kernel when
223 upgrading in case your new kernel doesn't work (and report the
224 breakage to current@freebsd.org).
226 As of 19990421 the remaining problems/quirks are
228 o sio no longer supports pnp nor pccard. This will be corrected,
229 but the new pccard code needs to be completed.
230 o Some of the sound drivers broke for some people. It seems
231 inconsistant as to who/what/when/where things broke.
232 o Duplicate device entries in your config do not work. Previously
233 they were silently ignored. psm0 seems to be the most common
234 duplicate choice, although some reports have come in from people
235 that wired their scsi disk entries.
236 o You must move the keyboard and mouse attachments from the
237 isa bus to the atkbdc bus. See GENERIC for details.
238 o Machines with multiple host-pci bridges (Intel 450NX) will not
239 probe the second pci bus.
240 o Some probe ordering may have changed, so device naming may change
241 with the new kernel. If you have multiple devices, please double
242 check to make sure they didn't move. This is especially true
243 for cards on different buses.
244 o The bus attachment for vga0 is always isa0 and never pci0 when
245 it is in fact a pci card. It is safe to ignore this.
246 o The format of the boot messages has changed (and is not
247 guaranteed to be constant for a while) so you may see this
248 in some shell scripts that diff dmesg from day to day as well
249 as scripts that parse dmesg output.
252 cc -aout sometimes has problems compiling with -g, remove -g
253 from those compilation units affected until this is corrected.
255 cc -aout has problems with producing some threaded libraries,
256 so make world -DWANT_AOUT is not functional at this time.
258 Since make world for a.out isn't functional, you cannot do
259 make aout-to-elf from a pre-egcs a.out system. To work around
260 this problem, make aout-to-elf using 3.1-stable first (or a
261 pre egcs -current) and then a simple make world will take you
262 the rest of the way with a -current source base.
265 Make -j works again for make world. As always, use it with
266 care, and be sure to try a make world w/o -j before reporting
267 problems (that is, know if the problem exists w/o -j before
268 reporting the problem with -j).
271 Note cc -aout, which had been broken since the conversion to
272 egcs, now supposedly works. If you have rebuilt things like
273 XFree86 a.out libraries, you should rebuild them again or
274 progams that use them, including netscape, will fail to work.
277 NOTE: New c++ compiler cannot be used with c++ binaries from
278 the old compiler and vice versa.
281 In recent days egcs has been imported into the tree. A number
282 of problems have been discussed in -current. Here is a highlight
283 of a few of the more common ones. With the exception of make
284 -j n, they have been claimed to have been fixed.
286 c++ is broken after make world: This is correct. Because we
287 changed compilers two make worlds are necessary to get C++
288 working again. The code generated by the old compiler and new
289 compiler are not compatible, so things wind up being
292 cpp is broken in make world: There was a window where cpp
293 would be built incorrectly. The fix for this is
294 cd src/gnu/usr.bin/cc
298 and this should correct your problems. See the -current
299 archives for a version of this that does moer cleaning.
301 Make -j n doesn't work. Work contiunes to make this work,
302 I've seen no reports of success as of April 7th.
305 Previously, one would define "NOAOUT" to keep from building
306 the legacy a.out bits. Now one would define "WANT_AOUT" to
310 The name of the old wd.c and atapi.c based CDROM driver has
311 been changed back to wcd. So update your config file to use
312 "device wcd" instead of "device acd".
315 For those of you using the VN device as a loadable module,
316 please be aware that the new VN device has been committed to
317 -4.x and cannot yet be used as a loadable module. This will
318 be fixed in the future.
321 New loader.rc mechanism. Please see src/sys/boot/README for
325 struct proc size changed. Recompile kernel and the
326 usual suspects. Make world if in doubt.
329 The nlpt driver has changed names back to be the lpt driver.
330 See ppbus(4) or http://www.freebsd.org/~nsouch/ppbus.html
331 for proper configuration details.
334 The 'lpt' driver is now obsolete. Replace it with the 'nlpt'
335 driver and 'ppbus' controller combination.
338 New devstat API requires recompilation of libdevstat, systat,
339 iostat, vmstat and rpc.rstatd. A new kernel is also required.
340 make world + building a kernel should do all of this. Any
341 ports that use devstat need to be recompiled as well.
344 Linux threads options has gone away (they are now standard in
345 the FreeBSD kernel). A recompile of all libkvm using programs
346 is in order (or better yet a make world).
349 On or about this date there was a small window when the boot
350 blocks had some minor problems which seemed to force one to
351 edit /etc/fstab. This has been corrected, if you are seeing this
352 problem, please rebuild and reinstall your boot blocks.
355 Vinum has changed. The "vinum read" command has changed. For
358 http://www.freebsd.org/cgi/getmsg.cgi?fetch=800363+0+current/freebsd-current
362 Matt Dillon committed a boatload of VM changes, for
363 information please see
365 http://www.freebsd.org/cgi/getmsg.cgi?fetch=886676+0+current/freebsd-current
367 http://www.freebsd.org/cgi/getmsg.cgi?fetch=827400+0+current/freebsd-current
369 for details. These changes will likely not impact anybody,
370 but large chagnes to the VM need at least a heads up.
373 Stable branch created. You might want to consider using this
374 branch. It is tagged with RELENG_3.
377 More work on the syscons driver has been committed. Since
378 files moved around, you will need to reconfigure your kernel,
379 and make clean; make depend before rebuilding the kernel. No
380 config file changes are needed.
383 New keyboard and video card drivers are introduced as the first
384 stage of console driver reorganization. You are required to
385 update the kernel configuration file and rebuild the kernel.
386 kbdcontrol, vidcontrol, and screen savers also need recompilation.
387 The instruction can be found in
389 http://www.freebsd.org/~yokota/sc_update.txt
391 It has notes on splash screen too.
394 Robert Nordier was kind enough to make this page to enable people to
395 install the new bootblocks:
397 http://www.freebsd.org/~rnordier/boot.txt
399 When updating to ELF, make sure that you have updated your
400 /etc/rc files which have different ldconfig invocations for
401 elf and aout. Otherwise things like X will stop working with
402 messages about being unable to find library files. The
403 mergemaster utility in ports/sysutils/mergemaster helps to
404 keep critical files like this in sync, and its use is
408 Information about ELF day (see 19981230) can be found in
410 http://www.freebsd.org/~peter/elfday.html
412 about the upcoming change, its motivations and instructions
413 for doing the upgrade.
416 You should install new bootblocks now. The ELF kernel will
417 become default soon. In addition, you'll need to upgrade
418 your userland programs to ELF before then as well. Use
419 make aout-to-elf to upgrade your userland programs (old
420 a.out programs in, for example, /usr/local/bin will
421 continue to work, even after the upgrade). See src/Makefile
425 The old wcd driver has been deleted from the kernel. The
426 driver that replaces it is named acd. You'll need to change
427 this in your configuration files.
429 Failure to do this will result in "ATAPI CD-ROMs not
430 configured" at boot time.
432 The floppy tape driver (ft) has been removed from the kernel,
433 with no replacement driver.
436 New groups from 19981201 commented out of mtree, so they
437 aren't strictly needed, but still a good idea to have.
440 New user/group added: bind. From src/etc/master.passwd and
442 % grep <newstuff> /usr/src/etc/group
444 % grep <newstuff> /usr/src/etc/master.passwd
445 tty:*:4:65533::0:0:Tty Sandbox:/:/sbin/nologin
446 kmem:*:5:65533::0:0:KMem Sandbox:/:/sbin/nologin
447 bind:*:53:53::0:0:Bind Sandbox:/:/sbin/nologin
450 PAM integrated into the tree. Requires new /etc/pam.conf file
451 to silence warnings from authentication programs (login, etc).
452 See src/etc/pam.conf for a sample.
454 This file contains a list, in reverse chronologocal order, of major
455 breakages in tracking -current. Not all things will be listed here,
456 and it only starts on November 18, 1998. If you have an earlier
457 version of FreeBSD, you are on your own to get to November 18, 1998.
459 Please filter your entries through Warner (imp@village.org) so that
460 the style, formatting, etc of this file can be maintained.
