UPDATING revision 62103
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 820000624: 9 Mark Murray just committed the first parts of a cleanup of 10 /dev/zero, et al. This is also cleaning up /dev/random. 11 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD 12 -CURRENT FROM THIS POINT FORWARD for cryptographic services 13 until Mark can merge in the fixes to this work in progress. 14 openssh and openssl should not be used to generate keys from this 15 date to the completion of the work. 16 1720000622: 18 The license on the softupdates is now a standard 2 clause 19 BSD license. You may need to remove your symbolic links 20 that used to be required when updating. 21 2220000621: 23 Scott Flatman <sf@aracnet.com> sent in a decent writeup on 24 the config file update procedure. 25 http://people.freebsd.org/~imp/config-upd.html 26 2720000620: 28 Binutils 2.10 have hit the tree, or will shortly. As soon 29 as they do, the problem noted in 20000522 will be resolved and 30 that workaround will no longer be required. 31 3220000615: 33 phk removed the compatibility creation of wd devices in the 34 ad driver. If you haven't done so already, you must update 35 your fstab, etc to use the ad devices instead of the wd 36 devices. 37 38 In addition, you'll need to update your boot blocks to a 39 more modern version, if you haven't already done so. Modern 40 here means 4.0 release or newer (although older releases 41 may work). 42 4320000612: 44 Peter took an axe to config(8). Besure that you read his mail 45 on the topic before even thinking about updating. You will 46 need to create a /boot/devices.hints or add a hints directive 47 to your config file to compile them in statically. The format 48 of the config file has changed as well. Please see LINT, 49 GENERIC or NEWCARD for examples of the new format. 50 5120000522: 52 A new set of binutils went into the tree today. Anybody 53 building a kernel after this point is advised that they need 54 to rebuild their binutils (or better yet do a 55 buildworld/installworld) before building a new kernel. 56 57 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf 58 or MALLOC_OPTIONS env var) J will cause ld to dump core. It 59 is recommended that you don't set this option until the problem 60 is resolved. 61 6220000513: 63 The ethernet drivers were all updated to clean up the BPF handling. 64 6520000510: 66 The problems with boot blocks on the alphas have been corrected. 67 This will require some care in updating alphas. A new libstand 68 is requires for the boot blocks to build properly. 69 7020000503: 71 Recompile all kld modules. Proper version dependency info 72 is now available. 73 7420000502: 75 Modules have been disconnected from the buildworld tree and 76 connected to the kernel building instead. 77 782000427: 79 You may need to build gperf 80 cd /usr/src/gnu/usr.bin/gperf && make depend all install 81 when upgrading from 4.0 -> current. The build system now uses 82 an option only in -current. 83 8420000417: 85 The method that we brand ELF binaries has changed to be more 86 acceptible to the binutils maintainers. You will need to 87 rebrand your ELF binaries that aren't native. One problem 88 binary is the Linux ldconfig. After your make world, but 89 before you reboot, you'll neeed to issue: 90 brandelf -t Linux /compat/linux/sbin/ldconfig 91 if you have Linux compatibility enabled on your machine. 92 9320000320: 94 If you have really bad/marginal IDE drives, you may find they 95 don't work well. Use pio mode instead. The easiest way to 96 cope if you have a problem combination is to add: 97 /sbin/sysctl -w hw.atamodes=pio,pio,pio,pio 98 to the start of /etc/rc.conf. 99 10020000319: 101 The ISA and PCI compatability shims have been connected to the 102 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old 103 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must 104 include the appropriate option in your kernel config. Drivers 105 using the shims should be updated or they won't ship with 106 5.0-RELEASE, targeted for 2001. 107 10820000318: 109 We've entered the tradtional post release dumping party. 110 Large kernel changes are being committed and are in the 111 works. It is important to keep the systems' klds and kernel 112 in sync as kernel interfaces and structures are changing. 113 Before reporting kernel panics, make sure that all modules 114 that you are loading are up to date. 115 11620000315: 117 If you are upgrading from an older version of FreeBSD, you 118 need to update your boot blocks as well. 'disklabel -B ad0' 119 will do the trick. This isn't critical until you remove your 120 wd device entries in /dev, at which point your system will not 121 boot. 122 12320000315: 124 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how 125 to upgrade to 4.0 from 3.x. 126 127COMMON ITEMS: 128 129 To build a kernel 130 ----------------- 131 Update config, genassym and go: 132 config YOUR_KERNEL_HERE [1] 133 cd ../../compile/YOUR_KERNEL_HERE 134 make depend && make 135 make install 136 [1] If upgrading, add -r won't hurt and sometimes helps. 137 138 To rebuild everything 139 --------------------- 140 make world 141 142 To upgrade from 4.0-stable to current 143 ------------------------------------- 144 make buildworld 145 make buildkernel KERNEL=YOUR_KERNEL_HERE 146 make installkernel KERNEL=YOUR_KERNEL_HERE 147 make installworld 148 <reboot> 149 150 Make sure that you've read the UPDATING file to understand 151 the tweaks to various things you need. At this point in the 152 life cycloe of current, things change often and you are on 153 your own to cope. 154 155FORMAT: 156 157This file contains a list, in reverse chronologocal order, of major 158breakages in tracking -current. Not all things will be listed here, 159and it only starts on March 15, 2000. Updating files can found in 160previous releases if your system is older than this. 161 162Please filter your entries through Warner Losh (imp@village.org) so 163that the style, formatting, etc of this file can be maintained. 164 165$FreeBSD: head/UPDATING 62103 2000-06-26 05:54:02Z imp $ 166
