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. 5 619990801: 7 Changes to the pccardd kernel interface require that you recompile 8 pccardd for new kernel. 9 1019980725: 11 The ipfw interface to the kernel has changed. You will need to 12 recompile ipfw programs for the new kernel. 13 1419990715: 15 The bpfilter device has been renamed to bpf. You will need to 16 change your config files in order to enable this in newer kernels. 17 1819990704: 19 src/contrib/sys/softupdates is moving to 20 src/sys/contrib/softupdates. Update your symbolic links/etc. 21 2219990702: 23 Major changes have been made to vinum and its interface. See 24 the man page (vinum(8)) for details. Look at the concat, 25 mirror and stripe commands, as well as the SIMPLIFIED 26 CONFIGURATION section. 27 2819990628: 29 Newsyslog.conf has had a minor, but potentially dangerous, 30 change to its username/group syntax. The old syntax was 31 user.group, while the new syntax is user:group. 32 3319990627: 34 Inetd wrapping default has changed. Please see the updated 35 man page for details. 36 3719990623: 38 Compaq Smart Raid driver committed as ida. 39 4019990622: 41 The second phase of syscons cleanup has happened. Some 42 functionality has been made optional. For details, see 43 http://www.freebsd.org/~yokota/sc_update-June.txt 44 Everyone will need to re-config(8) their kernels, but old 45 binaries will work with the new kernel. 46 4719990620: 48 IPFW uid/gid-based filtering support has been committed. This 49 breaks binary compatibility with previous copies of 50 ipfw(8). Any utilities using the ioctl()s of ipfw (especially 51 ipfw(8)) need to be recompiled with the newest headers 52 installed. 53 5419990618: 55 Inetd now wraps all stream-based services, including internals. 56 Syslog "severity" options are honoured. Installed syslog.conf 57 and hosts.allow should be checked. 58 5919990509: 60 Most of the problems with newbus have been corrected, but 61 it is still current and evolving. 62 63 libcam's ABI has changed. You must recompile the world and 64 any ports that use it. 65 6619990427: 67 Massive changes to SMP went into the tree that should speed 68 things up. However, if you experience problems with SMP 69 machines, you can back off to the PRE_SMP_VMSHARE tag in the 70 CVS repository (or run an MP kernel). 71 7219990420: 73 Pccardd and the pccard bus in general seem to be broken or 74 most people. Soren has patches to make it better for some, 75 but not all people. Work is underway to make it better for 76 all people. 77 7819990416: 79 new bus changes integrated into -current. Many problems were 80 initially reported, but most have been fixed. You'll need a 81 new config and to tweak your kernel config file the way that 82 GENERIC was tweaked. Keep a copy of your old kernel when 83 upgrading in case your new kernel doesn't work (and report the 84 breakage to current@freebsd.org). 85 86 As of 19990421 the remaining problems/quirks are 87 88 o sio no longer supports pnp nor pccard. This will be corrected, 89 but the new pccard code needs to be completed. 90 o Some of the sound drivers broke for some people. It seems 91 inconsistant as to who/what/when/where things broke. 92 o Duplicate device entries in your config do not work. Previously 93 they were silently ignored. psm0 seems to be the most common 94 duplicate choice, although some reports have come in from people 95 that wired their scsi disk entries. 96 o You must move the keyboard and mouse attachments from the 97 isa bus to the atkbdc bus. See GENERIC for details. 98 o Machines with multiple host-pci bridges (Intel 450NX) will not 99 probe the second pci bus. 100 o Some probe ordering may have changed, so device naming may change 101 with the new kernel. If you have multiple devices, please double 102 check to make sure they didn't move. This is especially true 103 for cards on different buses. 104 o The bus attachment for vga0 is always isa0 and never pci0 when 105 it is in fact a pci card. It is safe to ignore this. 106 o The format of the boot messages has changed (and is not 107 guaranteed to be constant for a while) so you may see this 108 in some shell scripts that diff dmesg from day to day as well 109 as scripts that parse dmesg output. 110 11119990414: 112 cc -aout sometimes has problems compiling with -g, remove -g 113 from those compilation units affected until this is corrected. 114 115 cc -aout has problems with producing some threaded libraries, 116 so make world -DWANT_AOUT is not functional at this time. 117 118 Since make world for a.out isn't functional, you cannot do 119 make aout-to-elf from a pre-egcs a.out system. To work around 120 this problem, make aout-to-elf using 3.1-stable first (or a 121 pre egcs -current) and then a simple make world will take you 122 the rest of the way with a -current source base. 123 12419990413: 125 Make -j works again for make world. As always, use it with 126 care, and be sure to try a make world w/o -j before reporting 127 problems (that is, know if the problem exists w/o -j before 128 reporting the problem with -j). 129 13019990413: 131 Note cc -aout, which had been broken since the conversion to 132 egcs, now supposedly works. If you have rebuilt things like 133 XFree86 a.out libraries, you should rebuild them again or 134 progams that use them, including netscape, will fail to work. 135 13619990409: 137 NOTE: New c++ compiler cannot be used with c++ binaries from 138 the old compiler and vice versa. 139 14019990408: 141 In recent days egcs has been imported into the tree. A number 142 of problems have been discussed in -current. Here is a highlight 143 of a few of the more common ones. With the exception of make 144 -j n, they have been claimed to have been fixed. 145 146 c++ is broken after make world: This is correct. Because we 147 changed compilers two make worlds are necessary to get C++ 148 working again. The code generated by the old compiler and new 149 compiler are not compatible, so things wind up being 150 undefined. 151 152 cpp is broken in make world: There was a window where cpp 153 would be built incorrectly. The fix for this is 154 cd src/gnu/usr.bin/cc 155 make clean 156 make all 157 make install 158 and this should correct your problems. See the -current 159 archives for a version of this that does moer cleaning. 160 161 Make -j n doesn't work. Work contiunes to make this work, 162 I've seen no reports of success as of April 7th. 163 16419990329: 165 Previously, one would define "NOAOUT" to keep from building 166 the legacy a.out bits. Now one would define "WANT_AOUT" to 167 build them. 168 16919990316: 170 The name of the old wd.c and atapi.c based CDROM driver has 171 been changed back to wcd. So update your config file to use 172 "device wcd" instead of "device acd". 173 17419990314: 175 For those of you using the VN device as a loadable module, 176 please be aware that the new VN device has been committed to 177 -4.x and cannot yet be used as a loadable module. This will 178 be fixed in the future. 179 18019990309: 181 New loader.rc mechanism. Please see src/sys/boot/README for 182 details. 183 18419990225: 185 struct proc size changed. Recompile kernel and the 186 usual suspects. Make world if in doubt. 187 18819990214: 189 The nlpt driver has changed names back to be the lpt driver. 190 See ppbus(4) or http://www.freebsd.org/~nsouch/ppbus.html 191 for proper configuration details. 192 19319990210: 194 The 'lpt' driver is now obsolete. Replace it with the 'nlpt' 195 driver and 'ppbus' controller combination. 196 19719990209: 198 New devstat API requires recompilation of libdevstat, systat, 199 iostat, vmstat and rpc.rstatd. A new kernel is also required. 200 make world + building a kernel should do all of this. Any 201 ports that use devstat need to be recompiled as well. 202 20319990125: 204 Linux threads options has gone away (they are now standard in 205 the FreeBSD kernel). A recompile of all libkvm using programs 206 is in order (or better yet a make world). 207 20819990122: 209 On or about this date there was a small window when the boot 210 blocks had some minor problems which seemed to force one to 211 edit /etc/fstab. This has been corrected, if you are seeing this 212 problem, please rebuild and reinstall your boot blocks. 213 21419990121: 215 Vinum has changed. The "vinum read" command has changed. For 216 updates, please see 217 218http://www.freebsd.org/cgi/getmsg.cgi?fetch=800363+0+current/freebsd-current 219 220 for details. 221 222 Matt Dillon committed a boatload of VM changes, for 223 information please see 224 225http://www.freebsd.org/cgi/getmsg.cgi?fetch=886676+0+current/freebsd-current 226 or 227http://www.freebsd.org/cgi/getmsg.cgi?fetch=827400+0+current/freebsd-current 228 229 for details. These changes will likely not impact anybody, 230 but large chagnes to the VM need at least a heads up. 231 23219990120: 233 Stable branch created. You might want to consider using this 234 branch. It is tagged with RELENG_3. 235 23619990119: 237 More work on the syscons driver has been committed. Since 238 files moved around, you will need to reconfigure your kernel, 239 and make clean; make depend before rebuilding the kernel. No 240 config file changes are needed. 241 24219990111: 243 New keyboard and video card drivers are introduced as the first 244 stage of console driver reorganization. You are required to 245 update the kernel configuration file and rebuild the kernel. 246 kbdcontrol, vidcontrol, and screen savers also need recompilation. 247 The instruction can be found in 248 249 http://www.freebsd.org/~yokota/sc_update.txt 250 251 It has notes on splash screen too. 252 25319990106: 254 Robert Nordier was kind enough to make this page to enable people to 255 install the new bootblocks: 256 257 http://www.freebsd.org/~rnordier/boot.txt 258 259 When updating to ELF, make sure that you have updated your 260 /etc/rc files which have different ldconfig invocations for 261 elf and aout. Otherwise things like X will stop working with 262 messages about being unable to find library files. The 263 mergemaster utility in ports/sysutils/mergemaster helps to 264 keep critical files like this in sync, and its use is 265 recommended. 266 26719990104: 268 Information about ELF day (see 19981230) can be found in 269 270 http://www.freebsd.org/~peter/elfday.html 271 272 about the upcoming change, its motivations and instructions 273 for doing the upgrade. 274 27519981230: 276 You should install new bootblocks now. The ELF kernel will 277 become default soon. In addition, you'll need to upgrade 278 your userland programs to ELF before then as well. Use 279 make aout-to-elf to upgrade your userland programs (old 280 a.out programs in, for example, /usr/local/bin will 281 continue to work, even after the upgrade). See src/Makefile 282 for more details. 283 28419981224: 285 The old wcd driver has been deleted from the kernel. The 286 driver that replaces it is named acd. You'll need to change 287 this in your configuration files. 288 289 Failure to do this will result in "ATAPI CD-ROMs not 290 configured" at boot time. 291 292 The floppy tape driver (ft) has been removed from the kernel, 293 with no replacement driver. 294 29519981202: 296 New groups from 19981201 commented out of mtree, so they 297 aren't strictly needed, but still a good idea to have. 298 29919981201: 300 New user/group added: bind. From src/etc/master.passwd and 301 src/etc/group: 302 % grep <newstuff> /usr/src/etc/group 303 bind:*:53: 304 % grep <newstuff> /usr/src/etc/master.passwd 305 tty:*:4:65533::0:0:Tty Sandbox:/:/sbin/nologin 306 kmem:*:5:65533::0:0:KMem Sandbox:/:/sbin/nologin 307 bind:*:53:53::0:0:Bind Sandbox:/:/sbin/nologin 308 30919981118: 310 PAM integrated into the tree. Requires new /etc/pam.conf file 311 to silence warnings from authentication programs (login, etc). 312 See src/etc/pam.conf for a sample. 313 314This file contains a list, in reverse chronologocal order, of major 315breakages in tracking -current. Not all things will be listed here, 316and it only starts on Novemeber 18, 1998. If you have an earlier 317version of FreeBSD, you are on your own to get to November 18, 1998. 318 319Please filter your entries through Warner (imp@village.org) so that 320the style, formatting, etc of this file can be maintained. 321 322$Id: UPDATING,v 1.39 1999/08/01 18:19:03 imp Exp $ 323
