10
11 20081128:
12 FreeBSD 6.4-RELEASE
13
14 20080904:
15 ntpd upgraded to 4.2.4p5.
16
17 20080118:
18 FreeBSD 6.3-RELEASE
19
20 20071126:
21 The AT keyboard emulation of sunkbd(4) has been turned on
22 by default. In order to make the special symbols of the Sun
23 keyboards driven by sunkbd(4) work under X these now have
24 to be configured the same way as Sun USB keyboards driven
25 by ukbd(4) (which also does AT keyboard emulation), f.e.:
26
27 Option "XkbLayout" "us"
28 Option "XkbRules" "xorg"
29 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us"
30
31 20071024:
32 A breakage was introduced in libc and fixed later. Make sure
33 you have lib/Makefile rev 1.205.2.4. If it already breaks your
34 world, you can recover it by
35
36 - reboot to single user mode, make sure you use /rescue/sh
37 instead of /bin/sh
38 - use /rescue/chflags to remove schg flag on /lib/libc.so.6
39 - use /rescue/cp to copy libc.so.6 from /usr/obj to /lib/libc.so.6
40 - continue installworld, you should be fine now
41
42 20070806:
43 An incorrect field size in an ioctl struct for if_bridge(4) has been
44 corrected, ifconfig(8) will need to be recompilied.
45
46 20070426:
47 The ABI breakage in sendmail(8)'s libmilter has been repaired
48 so it is no longer necessary to recompile mail filters (aka,
49 milters). If you recompiled mail filters after the 20070411
50 note, it is not necessary to recompile them again.
51
52 20070411:
53 sendmail(8) has been updated to version 8.14.1. Mail filters
54 (aka, milters) compiled against the libmilter included in the
55 base operating system should be recompiled.
56
57 20070115:
58 FreeBSD 6.2-RELEASE
59
60 20060902:
61 The IEEE80211_IOC_STA_INFO ioctl was updated to take a mac
62 address parameter. Binaries using the old ioctl number will
63 continue to work but user applications that use this must
64 be updated (none exist in the base system).
65
66 20060818:
67 The NMBCLUSTERS kernel option has been removed because it is obsolete.
68 Use the kern.ipc.nmbclusters loader(8) tunable instead.
69
70 20060816:
71 The IPFIREWALL_FORWARD_EXTENDED option is gone and the behaviour
72 for IPFIREWALL_FORWARD is now as it was before when it was first
73 committed and for years thereafter. The behaviour is now ON.
74
75 20060806:
76 The interface version of the i4b kernel part has changed. So
77 after updating the kernel sources and compiling a new kernel,
78 the i4b user space tools in "/usr/src/usr.sbin/i4b" must also
79 be rebuilt, and vice versa. This also applies to other tools
80 using the i4b kernel interface to userland.
81
82 20060711:
83 The iwi(4) was updated to use the firmware(9) framework. In order
84 for it to work you need a port change from net/iwi-firmware to
85 net/iwi-firmware-kmod.
86
87 20060506:
88 FreeBSD 6.1-RELEASE
89
90 20060309:
91 The support for Linux applications the 3dfx kernel module used
92 to provide is in a separate module named 3dfx_linux now. The
93 latter will pull in 3dfx.ko and linux.ko through its dependencies
94 when loaded.
95
96 20060211:
97 An IPv6 support of ipfw was enabled by default. If you don't
98 want to filter an IPv6 by ipfw, please add following line into
99 your ipfw rule:
100
101 pass ip6 from any to any
102
103 20060210:
104 Now most modules get their build-time options from the kernel
105 configuration file. A few modules still have fixed options
106 due to their non-conformant implementation, but they will be
107 corrected eventually. You may need to review the options of
108 the modules in use, explicitly specify the non-default options
109 in the kernel configuration file, and rebuild the kernel and
110 modules afterwards.
111
112 20060204:
113 The 'audit' group was added to support the new auditing functionality
114 in the base system. Be sure to follow the directions for updating,
115 including the requirement to run mergemaster -p.
116
117 20060127:
118 The i386 loader(8) now defaults to the serial speed set by the
119 previous boot stage, if the comconsole is already in use. If
120 you've changed BOOT_COMCONSOLE_SPEED in make.conf(5) and
121 installed a new loader, but have not rebuilt and reinstalled the
122 boot blocks, then your loader will leave the console at 9600
123 baud. Either install the new boot blocks, or set
124 comconsole_speed in loader.conf(5). Note that the new boot
125 blocks also support a -S<speed> flag described in boot(8).
126
127 20060122:
128 /etc/rc.d/ppp-user has been renamed to /etc/rc.d/ppp.
129 Its /etc/rc.conf.d configuration file has been `ppp' from
130 the beginning, and hence there is no need to touch it.
131
132 20060113:
133 si(4)'s device files now contain the unit number.
134 Uses of {cua,tty}A[0-9a-f] should be replaced by {cua,tty}A0[0-9a-f].
135
136 20051230:
137 A lot of fixes and new features in the soundsystem. To get all
138 benefits, you may want to recompile mplayer (if installed) after
139 booting the new world.
140
141 20051222:
142 Bug fixes to the trimdomain(3) function in libutil may result in
143 slight changes to the host names appearing in log files under
144 relatively rare circumstances.
145
146 20051220:
147 Scripts in the local_startup directories (as defined in
148 /etc/defaults/rc.conf) that have the new rc.d semantics will
149 now be run as part of the base system rcorder. If there are
150 errors or problems with one of these local scripts, it could
151 cause boot problems. If you encounter such problems, boot in
152 single user mode, remove that script from the */rc.d directory.
153 Please report the problem to the port's maintainer, and the
154 freebsd-ports@freebsd.org mailing list.
155
156 20051215:
157 The setkey(8) utility was moved from /usr/sbin/setkey to /sbin/setkey.
158 You may want to update scripts which depend on its location.
159
160 20051108:
161 rp(4)'s device files now contain the unit number.
162 Uses of {cua,tty}R[0-9a-f] should be replaced by {cua,tty}R0[0-9a-f].
163
164 20051101:
165 FreeBSD 6.0-RELEASE
166
167 20051001:
168 kern.polling.enable sysctl MIB is now deprecated. Use ifconfig(8)
169 to turn polling(4) on your interfaces.
170
171 20050722:
172 The ai_addrlen of a struct addrinfo was changed to a socklen_t
173 to conform to POSIX-2001. This change broke an ABI
174 compatibility on 64 bit architecture. You have to recompile
175 userland programs that use getaddrinfo(3) on 64 bit
176 architecture.
177
178 20050711:
179 RELENG_6 branched here.
180
181 20050629:
182 The pccard_ifconfig rc.conf variable has been removed and a new
183 variable, ifconfig_DEFAULT has been introduced. Unlike
184 pccard_ifconfig, ifconfig_DEFAULT applies to ALL interfaces that
185 do not have ifconfig_ifn entries rather than just those in
186 removable_interfaces.
187
188 20050616:
189 Some previous versions of PAM have permitted the use of
190 non-absolute paths in /etc/pam.conf or /etc/pam.d/* when referring
191 to third party PAM modules in /usr/local/lib. A change has been
192 made to require the use of absolute paths in order to avoid
193 ambiguity and dependence on library path configuration, which may
194 affect existing configurations.
195
196 20050610:
197 Major changes to network interface API. All drivers must be
198 recompiled. Drivers not in the base system will need to be
199 updated to the new APIs.
200
201 20050609:
202 Changes were made to kinfo_proc in sys/user.h. Please recompile
203 userland, or commands like `fstat', `pkill', `ps', `top' and `w'
204 will not behave correctly.
205
206 The API and ABI for hwpmc(4) have changed with the addition
207 of sampling support. Please recompile lib/libpmc(3) and
208 usr.sbin/{pmcstat,pmccontrol}.
209
210 20050606:
211 The OpenBSD dhclient was imported in place of the ISC dhclient
212 and the network interface configuration scripts were updated
213 accordingly. If you use DHCP to configure your interfaces, you
214 must now run devd. Also, DNS updating was lost so you will need
215 to find a workaround if you use this feature.
216
217 20050605:
218 if_bridge was added to the tree. This has changed struct ifnet.
219 Please recompile userland and all network related modules.
220
221 20050603:
222 The n_net of a struct netent was changed to an uint32_t, and
223 1st argument of getnetbyaddr() was changed to an uint32_t, to
224 conform to POSIX-2001. These changes broke an ABI
225 compatibility on 64 bit architecture. With these changes,
226 shlib major of libpcap was bumped. You have to recompile
227 userland programs that use getnetbyaddr(3), getnetbyname(3),
228 getnetent(3) and/or libpcap on 64 bit architecture.
229
230 20050528:
231 Kernel parsing of extra options on '#!' first lines of shell
232 scripts has changed. Lines with multiple options likely will
233 fail after this date. For full details, please see
234 http://people.freebsd.org/~gad/Updating-20050528.txt
235
236 20050503:
237 The packet filter (pf) code has been updated to OpenBSD 3.7
238 Please note the changed anchor syntax and the fact that
239 authpf(8) now needs a mounted fdescfs(5) to function.
240
241 20050415:
242 The NO_MIXED_MODE kernel option has been removed from the i386
243 amd64 platforms as its use has been superceded by the new local
244 APIC timer code. Any kernel config files containing this option
245 should be updated.
246
247 20050227:
248 The on-disk format of LC_CTYPE files was changed to be machine
249 independent. Please make sure NOT to use NO_CLEAN buildworld
250 when crossing this point. Crossing this point also requires
251 recompile or reinstall of all locale depended packages.
252
253 20050225:
254 The ifi_epoch member of struct if_data has been changed to
255 contain the uptime at which the interface was created or the
256 statistics zeroed rather then the wall clock time because
257 wallclock time may go backwards. This should have no impact
258 unless an snmp implementation is using this value (I know of
259 none at this point.)
260
261 20050224:
262 The acpi_perf and acpi_throttle drivers are now part of the
263 acpi(4) main module. They are no longer built separately.
264
265 20050223:
266 The layout of struct image_params has changed. You have to
267 recompile all compatibility modules (linux, svr4, etc) for use
268 with the new kernel.
269
270 20050223:
271 The p4tcc driver has been merged into cpufreq(4). This makes
272 "options CPU_ENABLE_TCC" obsolete. Please load cpufreq.ko or
273 compile in "device cpufreq" to restore this functionality.
274
275 20050220:
276 The responsibility of recomputing the file system summary of
277 a SoftUpdates-enabled dirty volume has been transferred to the
278 background fsck. A rebuild of fsck(8) utility is recommended
279 if you have updated the kernel.
280
281 To get the old behavior (recompute file system summary at mount
282 time), you can set vfs.ffs.compute_summary_at_mount=1 before
283 mounting the new volume.
284
285 20050206:
286 The cpufreq import is complete. As part of this, the sysctls for
287 acpi(4) throttling have been removed. The power_profile script
288 has been updated, so you can use performance/economy_cpu_freq in
289 rc.conf(5) to set AC on/offline cpu frequencies.
290
291 20050206:
292 NG_VERSION has been increased. Recompiling kernel (or ng_socket.ko)
293 requires recompiling libnetgraph and userland netgraph utilities.
294
295 20050114:
296 Support for abbreviated forms of a number of ipfw options is
297 now deprecated. Warnings are printed to stderr indicating the
298 correct full form when a match occurs. Some abbreviations may
299 be supported at a later date based on user feedback. To be
300 considered for support, abbreviations must be in use prior to
301 this commit and unlikely to be confused with current key words.
302
303 20041221:
304 By a popular demand, a lot of NOFOO options were renamed
305 to NO_FOO (see bsd.compat.mk for a full list). The old
306 spellings are still supported, but will cause annoying
307 warnings on stderr. Make sure you upgrade properly (see
308 the COMMON ITEMS: section later in this file).
309
310 20041219:
311 Auto-loading of ancillary wlan modules such as wlan_wep has
312 been temporarily disabled; you need to statically configure
313 the modules you need into your kernel or explicitly load them
314 prior to use. Specifically, if you intend to use WEP encryption
315 with an 802.11 device load/configure wlan_wep; if you want to
316 use WPA with the ath driver load/configure wlan_tkip, wlan_ccmp,
317 and wlan_xauth as required.
318
319 20041213:
320 The behaviour of ppp(8) has changed slightly. If lqr is enabled
321 (``enable lqr''), older versions would revert to LCP ECHO mode on
322 negotiation failure. Now, ``enable echo'' is required for this
323 behaviour. The ppp version number has been bumped to 3.4.2 to
324 reflect the change.
325
326 20041201:
327 The wlan support has been updated to split the crypto support
328 into separate modules. For static WEP you must configure the
329 wlan_wep module in your system or build and install the module
330 in place where it can be loaded (the kernel will auto-load
331 the module when a wep key is configured).
332
333 20041201:
334 The ath driver has been updated to split the tx rate control
335 algorithm into a separate module. You need to include either
336 ath_rate_onoe or ath_rate_amrr when configuring the kernel.
337
338 20041116:
339 Support for systems with an 80386 CPU has been removed. Please
340 use FreeBSD 5.x or earlier on systems with an 80386.
341
342 20041110:
343 We have had a hack which would mount the root filesystem
344 R/W if the device were named 'md*'. As part of the vnode
345 work I'm doing I have had to remove this hack. People
346 building systems which use preloaded MD root filesystems
347 may need to insert a "/sbin/mount -u -o rw /dev/md0 /" in
348 their /etc/rc scripts.
349
350 20041104:
351 FreeBSD 5.3 shipped here.
352
353 20041102:
354 The size of struct tcpcb has changed again due to the removal
355 of RFC1644 T/TCP. You have to recompile userland programs that
356 read kmem for tcp sockets directly (netstat, sockstat, etc.)
357
358 20041022:
359 The size of struct tcpcb has changed. You have to recompile
360 userland programs that read kmem for tcp sockets directly
361 (netstat, sockstat, etc.)
362
363 20041016:
364 RELENG_5 branched here. For older entries, please see updating
365 in the RELENG_5 branch.
366
367 COMMON ITEMS:
368
369 General Notes
370 -------------
371 Avoid using make -j when upgrading. From time to time in the
372 past there have been problems using -j with buildworld and/or
373 installworld. This is especially true when upgrading between
374 "distant" versions (eg one that cross a major release boundary
375 or several minor releases, or when several months have passed
376 on the -current branch).
377
378 Sometimes, obscure build problems are the result of environment
379 poisoning. This can happen because the make utility reads its
380 environment when searching for values for global variables.
381 To run your build attempts in an "environmental clean room",
382 prefix all make commands with 'env -i '. See the env(1) manual
383 page for more details.
384
385 Due to several updates to the build infrastructure, source
386 upgrades from versions prior to 5.3 no longer supported.
387
388 When upgrading from one major version to another it is generally
389 best to upgrade to the latest code in the currently installed branch
390 first, then do an upgrade to the new branch. This is the best-tested
391 upgrade path, and has the highest probability of being successful.
392 Please try this approach before reporting problems with a major
393 version upgrade.
394
395 To build a kernel
396 -----------------
397 If you are updating from a prior version of FreeBSD (even one just
398 a few days old), you should follow this procedure. With a
399 /usr/obj tree with a fresh buildworld,
400 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
401 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
402
403 To test a kernel once
404 ---------------------
405 If you just want to boot a kernel once (because you are not sure
406 if it works, or if you want to boot a known bad kernel to provide
407 debugging information) run
408 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel
409 nextboot -k testkernel
410
411 To just build a kernel when you know that it won't mess you up
412 --------------------------------------------------------------
413 This assumes you are already running a 6.X system. Replace
414 ${arch} with the architecture of your machine (e.g. "i386",
415 "alpha", "amd64", "ia64", "pc98", "sparc64", etc).
416
417 cd src/sys/${arch}/conf
418 config KERNEL_NAME_HERE
419 cd ../compile/KERNEL_NAME_HERE
420 make depend
421 make
422 make install
423
424 If this fails, go to the "To build a kernel" section.
425
426 To rebuild everything and install it on the current system.
427 -----------------------------------------------------------
428 # Note: sometimes if you are running current you gotta do more than
429 # is listed here if you are upgrading from a really old current.
430
431 <make sure you have good level 0 dumps>
432 make buildworld
433 make kernel KERNCONF=YOUR_KERNEL_HERE
434 [1]
435 <reboot in single user> [3]
436 mergemaster -p [5]
437 make installworld
438 make delete-old
439 mergemaster [4]
440 <reboot>
441
442
443 To cross-install current onto a separate partition
444 --------------------------------------------------
445 # In this approach we use a separate partition to hold
446 # current's root, 'usr', and 'var' directories. A partition
447 # holding "/", "/usr" and "/var" should be about 2GB in
448 # size.
449
450 <make sure you have good level 0 dumps>
451 <boot into -stable>
452 make buildworld
453 make buildkernel KERNCONF=YOUR_KERNEL_HERE
454 <maybe newfs current's root partition>
455 <mount current's root partition on directory ${CURRENT_ROOT}>
456 make installworld DESTDIR=${CURRENT_ROOT}
457 cd src/etc; make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd
458 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT}
459 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd
460 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition>
461 <reboot into current>
462 <do a "native" rebuild/install as described in the previous section>
463 <maybe install compatibility libraries from src/lib/compat>
464 <reboot>
465
466
467 To upgrade in-place from 5.x-stable or higher to 6.x-stable
468 -----------------------------------------------------------
469 <make sure you have good level 0 dumps>
470 make buildworld [9]
471 make kernel KERNCONF=YOUR_KERNEL_HERE [8]
472 [1]
473 <reboot in single user> [3]
474 mergemaster -p [5]
475 make installworld
476 make delete-old
477 mergemaster -i [4]
478 <reboot>
479
480 Make sure that you've read the UPDATING file to understand the
481 tweaks to various things you need. At this point in the life
482 cycle of current, things change often and you are on your own
483 to cope. The defaults can also change, so please read ALL of
484 the UPDATING entries.
485
486 Also, if you are tracking -current, you must be subscribed to
487 freebsd-current@freebsd.org. Make sure that before you update
488 your sources that you have read and understood all the recent
489 messages there. If in doubt, please track -stable which has
490 much fewer pitfalls.
491
492 [1] If you have third party modules, such as vmware, you
493 should disable them at this point so they don't crash your
494 system on reboot.
495
496 [3] From the bootblocks, boot -s, and then do
497 fsck -p
498 mount -u /
499 mount -a
500 cd src
501 adjkerntz -i # if CMOS is wall time
502 Also, when doing a major release upgrade, it is required that
503 you boot into single user mode to do the installworld.
504
505 [4] Note: This step is non-optional. Failure to do this step
506 can result in a significant reduction in the functionality of the
507 system. Attempting to do it by hand is not recommended and those
508 that pursue this avenue should read this file carefully, as well
509 as the archives of freebsd-current and freebsd-hackers mailing lists
510 for potential gotchas.
511
512 [5] Usually this step is a noop. However, from time to time
513 you may need to do this if you get unknown user in the following
514 step. It never hurts to do it all the time.
515
516 [8] In order to have a kernel that can run the 5.x binaries
517 needed to do an installworld, you must include the COMPAT_FREEBSD5
518 option in your kernel. Failure to do so may leave you with a system
519 that is hard to boot to recover. A similar kernel option COMPAT_FREEBSD5
520 is required to run the 5.x binaries on more recent kernels.
