UPDATING revision 63061
1Updating Information for FreeBSD current users 2 3This file is maintained by imp@village.org. Please send new entries 4directly to him. See end of file for further details. For commonly 5done items, please see the end of the file. Search for 'COMMON 6ITEMS:' 7 820000710: 9 /dev/random now has good entropy collection (from the keyboard 10 and sysmouse drivers). Please ensure that either `options 11 RANDOMDEV' is present in your kernel config file or that 12 `randomdev_load="YES"' is in your /boot/loader.conf. If you do 13 not have the /dev/random driver, OpenSSL (and consequently 14 lots of crypto tools (like SSH)) will fail with strange 15 errors. (see below, 20000624). 16 1720000709: 18 phk made the default options AJ. This may slow things down 19 and uncover other latent bugs in the code. If you need to run 20 at full speed, you can disable this by doing the following: 21 ln -s aj /etc/malloc.conf 22 2320000706: 24 libftpio's version was accidentally bumped a few days ago. This 25 has been corrected. You may need to remove /usr/lib/libftpio.so.6 26 before doing your next buildworld/installworld pair. It certainly 27 won't hurt to remove it before the update proceedure. It will 28 break fetch until a new one is built, but ftp can be used in the 29 interrum if needed. 30 3120000705: 32 The crypto packages have changed for the cvsup. This has been done 33 in a backward compatible way, but the old packages will go away at 34 some point in the future. Look at /usr/share/examples/cvsup for 35 details. 36 3720000704: 38 With the new sys/modules/sound/drivers/*, you will need to 39 set SYSDIR until you do an installworld after July 7th. 40 4120000704: 42 rc.shutdown and rc will now call the rc.d scripts with start 43 or stop. This may cause some harmless warnings from older 44 rc.d scripts that haven't been updated. 45 4620000630: 47 The libfetch based version of fetch has gone into the tree. 48 Minor problems may result on some of the less popular sites, 49 which should be reported to des@freebsd.org. 50 5120000625: 52 From approximately this date forward, one must have the crypto 53 system installed in order to build the system and kernel. 54 While not technically strictly true, one should treat it as 55 required and grab the crypto bits. If you are grabbing CVS 56 trees, src-all and cvs-crypto should be treated as if they 57 were required. You should check with the latest collections 58 to make sure that these haven't changed. 59 6020000624: 61 Mark Murray just committed the first parts of a cleanup of 62 /dev/zero, et al. This is also cleaning up /dev/random. 63 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD 64 -CURRENT FROM THIS POINT FORWARD for cryptographic services 65 until Mark can merge in the fixes to this work in progress. 66 openssh and openssl should not be used to generate keys from this 67 date to the completion of the work. 68 69 If you must operate at this reduced level of security, add ' 70 options RANDOMDEV' to your kernel or modload the randomdev 71 module. You may also need to copy a new MAKEDEV to /dev and 72 recreate the random and urandom devices. 73 7420000622: 75 The license on the softupdates is now a standard 2 clause 76 BSD license. You may need to remove your symbolic links 77 that used to be required when updating. 78 7920000621: 80 Scott Flatman <sf@aracnet.com> sent in a decent writeup on 81 the config file update procedure. 82 http://people.freebsd.org/~imp/config-upd.html 83 NOTE: LINT is gone. It has been replaced with NOTES. NOTES 84 isn't buildable. 85 8620000620: 87 Binutils 2.10 have hit the tree, or will shortly. As soon 88 as they do, the problem noted in 20000522 will be resolved and 89 that workaround will no longer be required. 90 9120000615: 92 phk removed the compatibility creation of wd devices in the 93 ad driver. If you haven't done so already, you must update 94 your fstab, etc to use the ad devices instead of the wd 95 devices. 96 97 In addition, you'll need to update your boot blocks to a 98 more modern version, if you haven't already done so. Modern 99 here means 4.0 release or newer (although older releases 100 may work). 101 10220000612: 103 Peter took an axe to config(8). Besure that you read his mail 104 on the topic before even thinking about updating. You will 105 need to create a /boot/devices.hints or add a hints directive 106 to your config file to compile them in statically. The format 107 of the config file has changed as well. Please see LINT, 108 GENERIC or NEWCARD for examples of the new format. 109 11020000522: 111 A new set of binutils went into the tree today. Anybody 112 building a kernel after this point is advised that they need 113 to rebuild their binutils (or better yet do a 114 buildworld/installworld) before building a new kernel. 115 116 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf 117 or MALLOC_OPTIONS env var) J will cause ld to dump core. It 118 is recommended that you don't set this option until the problem 119 is resolved. 120 12120000513: 122 The ethernet drivers were all updated to clean up the BPF handling. 123 12420000510: 125 The problems with boot blocks on the alphas have been corrected. 126 This will require some care in updating alphas. A new libstand 127 is requires for the boot blocks to build properly. 128 12920000503: 130 Recompile all kld modules. Proper version dependency info 131 is now available. 132 13320000502: 134 Modules have been disconnected from the buildworld tree and 135 connected to the kernel building instead. 136 1372000427: 138 You may need to build gperf 139 cd /usr/src/gnu/usr.bin/gperf && make depend all install 140 when upgrading from 4.0 -> current. The build system now uses 141 an option only in -current. 142 14320000417: 144 The method that we brand ELF binaries has changed to be more 145 acceptible to the binutils maintainers. You will need to 146 rebrand your ELF binaries that aren't native. One problem 147 binary is the Linux ldconfig. After your make world, but 148 before you reboot, you'll neeed to issue: 149 brandelf -t Linux /compat/linux/sbin/ldconfig 150 if you have Linux compatibility enabled on your machine. 151 15220000320: 153 If you have really bad/marginal IDE drives, you may find they 154 don't work well. Use pio mode instead. The easiest way to 155 cope if you have a problem combination is to add: 156 /sbin/sysctl -w hw.atamodes=pio,pio,pio,pio 157 to the start of /etc/rc.conf. 158 15920000319: 160 The ISA and PCI compatability shims have been connected to the 161 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old 162 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must 163 include the appropriate option in your kernel config. Drivers 164 using the shims should be updated or they won't ship with 165 5.0-RELEASE, targeted for 2001. 166 16720000318: 168 We've entered the tradtional post release dumping party. 169 Large kernel changes are being committed and are in the 170 works. It is important to keep the systems' klds and kernel 171 in sync as kernel interfaces and structures are changing. 172 Before reporting kernel panics, make sure that all modules 173 that you are loading are up to date. 174 17520000315: 176 If you are upgrading from an older version of FreeBSD, you 177 need to update your boot blocks as well. 'disklabel -B ad0' 178 will do the trick. This isn't critical until you remove your 179 wd device entries in /dev, at which point your system will not 180 boot. 181 18220000315: 183 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how 184 to upgrade to 4.0 from 3.x. 185 186COMMON ITEMS: 187 188 To build a kernel 189 ----------------- 190 Update config, genassym and go: 191 config YOUR_KERNEL_HERE [1] 192 cd ../../compile/YOUR_KERNEL_HERE 193 make depend && make 194 make install 195 [1] If upgrading, add -r won't hurt and sometimes helps. 196 197 To rebuild everything 198 --------------------- 199 make world 200 201 To upgrade from 4.0-stable to current 202 ------------------------------------- 203 make buildworld 204 make buildkernel KERNEL=YOUR_KERNEL_HERE 205 make installkernel KERNEL=YOUR_KERNEL_HERE 206 make installworld 207 <reboot> 208 209 Make sure that you've read the UPDATING file to understand 210 the tweaks to various things you need. At this point in the 211 life cycloe of current, things change often and you are on 212 your own to cope. 213 214FORMAT: 215 216This file contains a list, in reverse chronologocal order, of major 217breakages in tracking -current. Not all things will be listed here, 218and it only starts on March 15, 2000. Updating files can found in 219previous releases if your system is older than this. 220 221Please filter your entries through Warner Losh (imp@village.org) so 222that the style, formatting, etc of this file can be maintained. 223 224$FreeBSD: head/UPDATING 63061 2000-07-13 05:35:31Z imp $ 225
