1 Updating Information for FreeBSD current users

5 done items, please see the end of the file. Search for 'COMMON
9 If you use CVSUP or CTM to get CVS trees, AND you used to get
10 the old crypto files from internat.freebsd.org AND you check
11 out files from the CVS tree with the cvs command, please read
12 http://people.freebsd.org/~imp/internat.txt
13 for details on potential problems that you might have and how
16 If you are merely a mirror, or don't answer yes to each of the
17 clauses above, you needn't worry.
20 /etc/security has been updated to print the inode number of
21 setuid programs that have changed. You will see a large spike
22 in the number of changed programs the first time when you run
23 mergemaster to get a new /etc/security.
26 /dev/random now has good entropy collection (from the keyboard
27 and sysmouse drivers). Please ensure that either `options
28 RANDOMDEV' is present in your kernel config file or that
29 `randomdev_load="YES"' is in your /boot/loader.conf. If you do
30 not have the /dev/random driver, OpenSSL (and consequently
31 lots of crypto tools (like SSH)) will fail with strange
32 errors. (see below, 20000624).
35 phk made the default options AJ. This may slow things down
36 and uncover other latent bugs in the code. If you need to run
37 at full speed, you can disable this by doing the following:
38 ln -s aj /etc/malloc.conf
41 libftpio's version was accidentally bumped a few days ago. This
42 has been corrected. You may need to remove /usr/lib/libftpio.so.6
43 before doing your next buildworld/installworld pair. It certainly
44 won't hurt to remove it before the update proceedure. It will
45 break fetch until a new one is built, but ftp can be used in the
49 The crypto packages have changed for the cvsup. This has been done
50 in a backward compatible way, but the old packages will go away at
51 some point in the future. Look at /usr/share/examples/cvsup for
55 With the new sys/modules/sound/drivers/*, you will need to
56 set SYSDIR until you do an installworld after July 7th.
59 rc.shutdown and rc will now call the rc.d scripts with start
60 or stop. This may cause some harmless warnings from older
61 rc.d scripts that haven't been updated.
64 The libfetch based version of fetch has gone into the tree.
65 Minor problems may result on some of the less popular sites,
66 which should be reported to des@freebsd.org.
69 From approximately this date forward, one must have the crypto
70 system installed in order to build the system and kernel.
71 While not technically strictly true, one should treat it as
72 required and grab the crypto bits. If you are grabbing CVS
73 trees, src-all and cvs-crypto should be treated as if they
74 were required. You should check with the latest collections
75 to make sure that these haven't changed.
78 Mark Murray just committed the first parts of a cleanup of
79 /dev/zero, et al. This is also cleaning up /dev/random.
80 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD
81 -CURRENT FROM THIS POINT FORWARD for cryptographic services
82 until Mark can merge in the fixes to this work in progress.
83 openssh and openssl should not be used to generate keys from this
84 date to the completion of the work.
86 If you must operate at this reduced level of security, add '
87 options RANDOMDEV' to your kernel or modload the randomdev
88 module. You may also need to copy a new MAKEDEV to /dev and
89 recreate the random and urandom devices.
92 The license on the softupdates is now a standard 2 clause
93 BSD license. You may need to remove your symbolic links
94 that used to be required when updating.
97 Scott Flatman <sf@aracnet.com> sent in a decent writeup on
98 the config file update procedure.

100 NOTE: LINT is gone. It has been replaced with NOTES. NOTES
104 Binutils 2.10 have hit the tree, or will shortly. As soon
105 as they do, the problem noted in 20000522 will be resolved and
106 that workaround will no longer be required.
109 phk removed the compatibility creation of wd devices in the
110 ad driver. If you haven't done so already, you must update
111 your fstab, etc to use the ad devices instead of the wd
114 In addition, you'll need to update your boot blocks to a
115 more modern version, if you haven't already done so. Modern
116 here means 4.0 release or newer (although older releases
120 Peter took an axe to config(8). Besure that you read his mail
121 on the topic before even thinking about updating. You will
122 need to create a /boot/devices.hints or add a hints directive
123 to your config file to compile them in statically. The format
124 of the config file has changed as well. Please see LINT,
125 GENERIC or NEWCARD for examples of the new format.
128 A new set of binutils went into the tree today. Anybody
129 building a kernel after this point is advised that they need
130 to rebuild their binutils (or better yet do a
131 buildworld/installworld) before building a new kernel.
133 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf
134 or MALLOC_OPTIONS env var) J will cause ld to dump core. It
135 is recommended that you don't set this option until the problem
139 The ethernet drivers were all updated to clean up the BPF handling.
142 The problems with boot blocks on the alphas have been corrected.
143 This will require some care in updating alphas. A new libstand
144 is requires for the boot blocks to build properly.
147 Recompile all kld modules. Proper version dependency info
151 Modules have been disconnected from the buildworld tree and
152 connected to the kernel building instead.
155 You may need to build gperf
156 cd /usr/src/gnu/usr.bin/gperf && make depend all install
157 when upgrading from 4.0 -> current. The build system now uses
158 an option only in -current.
161 The method that we brand ELF binaries has changed to be more
162 acceptible to the binutils maintainers. You will need to
163 rebrand your ELF binaries that aren't native. One problem
164 binary is the Linux ldconfig. After your make world, but
165 before you reboot, you'll neeed to issue:
166 brandelf -t Linux /compat/linux/sbin/ldconfig
167 if you have Linux compatibility enabled on your machine.
170 If you have really bad/marginal IDE drives, you may find they
171 don't work well. Use pio mode instead. The easiest way to
172 cope if you have a problem combination is to add:
173 /sbin/sysctl -w hw.atamodes=pio,pio,pio,pio
174 to the start of /etc/rc.conf.
177 The ISA and PCI compatability shims have been connected to the
178 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old
179 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must
180 include the appropriate option in your kernel config. Drivers
181 using the shims should be updated or they won't ship with
182 5.0-RELEASE, targeted for 2001.
185 We've entered the tradtional post release dumping party.
186 Large kernel changes are being committed and are in the
187 works. It is important to keep the systems' klds and kernel
188 in sync as kernel interfaces and structures are changing.
189 Before reporting kernel panics, make sure that all modules
190 that you are loading are up to date.
193 If you are upgrading from an older version of FreeBSD, you
194 need to update your boot blocks as well. 'disklabel -B ad0'
195 will do the trick. This isn't critical until you remove your
196 wd device entries in /dev, at which point your system will not
200 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how
201 to upgrade to 4.0 from 3.x.
207 Update config, genassym and go:
208 config YOUR_KERNEL_HERE [1]
209 cd ../../compile/YOUR_KERNEL_HERE
212 [1] If upgrading, add -r won't hurt and sometimes helps.

226 Make sure that you've read the UPDATING file to understand
227 the tweaks to various things you need. At this point in the
228 life cycloe of current, things change often and you are on
233 This file contains a list, in reverse chronologocal order, of major
234 breakages in tracking -current. Not all things will be listed here,
235 and it only starts on March 15, 2000. Updating files can found in
236 previous releases if your system is older than this.
238 Please filter your entries through Warner Losh (imp@village.org) so
239 that the style, formatting, etc of this file can be maintained.
