UPDATING revision 51096
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 619990908: 7 The new miibus has been added to the system. If you are using 8 the dm, rl, sf, sis, ste, tl, wb or xl drivers, you need to 9 add "controller miibus0" to your config file. 10 1119990905: 12 /var/cron/log has been moved to /var/log/cron to get all the 13 log files in one place. 14 1519990831: 16 tn3270 has been removed from the based system and added as a port. 17 1819990830: 19 User-visible TCP timers are now expressed in units of 1ms, instead 20 of 500ms, so if you've customized any timer values under 21 ``net.inet.tcp'', multiply them by 500 to preserve TCP's behavior. 22 2319990828: 24 RCS Id tags changed to FreeBSD. This will cause huge cvsup 25 updates. 26 2719990821: 28 On 28-May-1999 libreadline was upgraded from readline-2.2 to 29 readline-4.0. At that time the shared library major version 30 number was bumped from "3" to "4". It has been deemed that 31 the interface change between readline-2.2 and readline-4.0 was 32 not suffient to warrant the version number bump. 33 34 Thus I have reverted it back to "3". You will need to perform 35 the below immediately before your next ``make world'': 36 cd /usr/lib 37 ls -l libreadline.so.4 38 (if you have /usr/lib/libreadline.so.4) 39 mv libreadline.so.4 libreadline.so.3 40 rm -f libreadline.so 41 ln -s libreadline.so.3 libreadline.so 42 4319990801: 44 Changes to the pccardd kernel interface require that you recompile 45 pccardd for new kernel. 46 4719980725: 48 The ipfw interface to the kernel has changed. You will need to 49 recompile ipfw programs for the new kernel. 50 5119990715: 52 The bpfilter device has been renamed to bpf. You will need to 53 change your config files in order to enable this in newer kernels. 54 5519990704: 56 src/contrib/sys/softupdates is moving to 57 src/sys/contrib/softupdates. Update your symbolic links/etc. 58 5919990702: 60 Major changes have been made to vinum and its interface. See 61 the man page (vinum(8)) for details. Look at the concat, 62 mirror and stripe commands, as well as the SIMPLIFIED 63 CONFIGURATION section. 64 6519990628: 66 Newsyslog.conf has had a minor, but potentially dangerous, 67 change to its username/group syntax. The old syntax was 68 user.group, while the new syntax is user:group. 69 7019990627: 71 Inetd wrapping default has changed. Please see the updated 72 man page for details. 73 7419990623: 75 Compaq Smart Raid driver committed as ida. 76 7719990622: 78 The second phase of syscons cleanup has happened. Some 79 functionality has been made optional. For details, see 80 http://www.freebsd.org/~yokota/sc_update-June.txt 81 Everyone will need to re-config(8) their kernels, but old 82 binaries will work with the new kernel. 83 8419990620: 85 IPFW uid/gid-based filtering support has been committed. This 86 breaks binary compatibility with previous copies of 87 ipfw(8). Any utilities using the ioctl()s of ipfw (especially 88 ipfw(8)) need to be recompiled with the newest headers 89 installed. 90 9119990618: 92 Inetd now wraps all stream-based services, including internals. 93 Syslog "severity" options are honoured. Installed syslog.conf 94 and hosts.allow should be checked. 95 9619990509: 97 Most of the problems with newbus have been corrected, but 98 it is still current and evolving. 99 100 libcam's ABI has changed. You must recompile the world and 101 any ports that use it. 102 10319990427: 104 Massive changes to SMP went into the tree that should speed 105 things up. However, if you experience problems with SMP 106 machines, you can back off to the PRE_SMP_VMSHARE tag in the 107 CVS repository (or run an MP kernel). 108 10919990420: 110 Pccardd and the pccard bus in general seem to be broken or 111 most people. Soren has patches to make it better for some, 112 but not all people. Work is underway to make it better for 113 all people. 114 11519990416: 116 new bus changes integrated into -current. Many problems were 117 initially reported, but most have been fixed. You'll need a 118 new config and to tweak your kernel config file the way that 119 GENERIC was tweaked. Keep a copy of your old kernel when 120 upgrading in case your new kernel doesn't work (and report the 121 breakage to current@freebsd.org). 122 123 As of 19990421 the remaining problems/quirks are 124 125 o sio no longer supports pnp nor pccard. This will be corrected, 126 but the new pccard code needs to be completed. 127 o Some of the sound drivers broke for some people. It seems 128 inconsistant as to who/what/when/where things broke. 129 o Duplicate device entries in your config do not work. Previously 130 they were silently ignored. psm0 seems to be the most common 131 duplicate choice, although some reports have come in from people 132 that wired their scsi disk entries. 133 o You must move the keyboard and mouse attachments from the 134 isa bus to the atkbdc bus. See GENERIC for details. 135 o Machines with multiple host-pci bridges (Intel 450NX) will not 136 probe the second pci bus. 137 o Some probe ordering may have changed, so device naming may change 138 with the new kernel. If you have multiple devices, please double 139 check to make sure they didn't move. This is especially true 140 for cards on different buses. 141 o The bus attachment for vga0 is always isa0 and never pci0 when 142 it is in fact a pci card. It is safe to ignore this. 143 o The format of the boot messages has changed (and is not 144 guaranteed to be constant for a while) so you may see this 145 in some shell scripts that diff dmesg from day to day as well 146 as scripts that parse dmesg output. 147 14819990414: 149 cc -aout sometimes has problems compiling with -g, remove -g 150 from those compilation units affected until this is corrected. 151 152 cc -aout has problems with producing some threaded libraries, 153 so make world -DWANT_AOUT is not functional at this time. 154 155 Since make world for a.out isn't functional, you cannot do 156 make aout-to-elf from a pre-egcs a.out system. To work around 157 this problem, make aout-to-elf using 3.1-stable first (or a 158 pre egcs -current) and then a simple make world will take you 159 the rest of the way with a -current source base. 160 16119990413: 162 Make -j works again for make world. As always, use it with 163 care, and be sure to try a make world w/o -j before reporting 164 problems (that is, know if the problem exists w/o -j before 165 reporting the problem with -j). 166 16719990413: 168 Note cc -aout, which had been broken since the conversion to 169 egcs, now supposedly works. If you have rebuilt things like 170 XFree86 a.out libraries, you should rebuild them again or 171 progams that use them, including netscape, will fail to work. 172 17319990409: 174 NOTE: New c++ compiler cannot be used with c++ binaries from 175 the old compiler and vice versa. 176 17719990408: 178 In recent days egcs has been imported into the tree. A number 179 of problems have been discussed in -current. Here is a highlight 180 of a few of the more common ones. With the exception of make 181 -j n, they have been claimed to have been fixed. 182 183 c++ is broken after make world: This is correct. Because we 184 changed compilers two make worlds are necessary to get C++ 185 working again. The code generated by the old compiler and new 186 compiler are not compatible, so things wind up being 187 undefined. 188 189 cpp is broken in make world: There was a window where cpp 190 would be built incorrectly. The fix for this is 191 cd src/gnu/usr.bin/cc 192 make clean 193 make all 194 make install 195 and this should correct your problems. See the -current 196 archives for a version of this that does moer cleaning. 197 198 Make -j n doesn't work. Work contiunes to make this work, 199 I've seen no reports of success as of April 7th. 200 20119990329: 202 Previously, one would define "NOAOUT" to keep from building 203 the legacy a.out bits. Now one would define "WANT_AOUT" to 204 build them. 205 20619990316: 207 The name of the old wd.c and atapi.c based CDROM driver has 208 been changed back to wcd. So update your config file to use 209 "device wcd" instead of "device acd". 210 21119990314: 212 For those of you using the VN device as a loadable module, 213 please be aware that the new VN device has been committed to 214 -4.x and cannot yet be used as a loadable module. This will 215 be fixed in the future. 216 21719990309: 218 New loader.rc mechanism. Please see src/sys/boot/README for 219 details. 220 22119990225: 222 struct proc size changed. Recompile kernel and the 223 usual suspects. Make world if in doubt. 224 22519990214: 226 The nlpt driver has changed names back to be the lpt driver. 227 See ppbus(4) or http://www.freebsd.org/~nsouch/ppbus.html 228 for proper configuration details. 229 23019990210: 231 The 'lpt' driver is now obsolete. Replace it with the 'nlpt' 232 driver and 'ppbus' controller combination. 233 23419990209: 235 New devstat API requires recompilation of libdevstat, systat, 236 iostat, vmstat and rpc.rstatd. A new kernel is also required. 237 make world + building a kernel should do all of this. Any 238 ports that use devstat need to be recompiled as well. 239 24019990125: 241 Linux threads options has gone away (they are now standard in 242 the FreeBSD kernel). A recompile of all libkvm using programs 243 is in order (or better yet a make world). 244 24519990122: 246 On or about this date there was a small window when the boot 247 blocks had some minor problems which seemed to force one to 248 edit /etc/fstab. This has been corrected, if you are seeing this 249 problem, please rebuild and reinstall your boot blocks. 250 25119990121: 252 Vinum has changed. The "vinum read" command has changed. For 253 updates, please see 254 255http://www.freebsd.org/cgi/getmsg.cgi?fetch=800363+0+current/freebsd-current 256 257 for details. 258 259 Matt Dillon committed a boatload of VM changes, for 260 information please see 261 262http://www.freebsd.org/cgi/getmsg.cgi?fetch=886676+0+current/freebsd-current 263 or 264http://www.freebsd.org/cgi/getmsg.cgi?fetch=827400+0+current/freebsd-current 265 266 for details. These changes will likely not impact anybody, 267 but large chagnes to the VM need at least a heads up. 268 26919990120: 270 Stable branch created. You might want to consider using this 271 branch. It is tagged with RELENG_3. 272 27319990119: 274 More work on the syscons driver has been committed. Since 275 files moved around, you will need to reconfigure your kernel, 276 and make clean; make depend before rebuilding the kernel. No 277 config file changes are needed. 278 27919990111: 280 New keyboard and video card drivers are introduced as the first 281 stage of console driver reorganization. You are required to 282 update the kernel configuration file and rebuild the kernel. 283 kbdcontrol, vidcontrol, and screen savers also need recompilation. 284 The instruction can be found in 285 286 http://www.freebsd.org/~yokota/sc_update.txt 287 288 It has notes on splash screen too. 289 29019990106: 291 Robert Nordier was kind enough to make this page to enable people to 292 install the new bootblocks: 293 294 http://www.freebsd.org/~rnordier/boot.txt 295 296 When updating to ELF, make sure that you have updated your 297 /etc/rc files which have different ldconfig invocations for 298 elf and aout. Otherwise things like X will stop working with 299 messages about being unable to find library files. The 300 mergemaster utility in ports/sysutils/mergemaster helps to 301 keep critical files like this in sync, and its use is 302 recommended. 303 30419990104: 305 Information about ELF day (see 19981230) can be found in 306 307 http://www.freebsd.org/~peter/elfday.html 308 309 about the upcoming change, its motivations and instructions 310 for doing the upgrade. 311 31219981230: 313 You should install new bootblocks now. The ELF kernel will 314 become default soon. In addition, you'll need to upgrade 315 your userland programs to ELF before then as well. Use 316 make aout-to-elf to upgrade your userland programs (old 317 a.out programs in, for example, /usr/local/bin will 318 continue to work, even after the upgrade). See src/Makefile 319 for more details. 320 32119981224: 322 The old wcd driver has been deleted from the kernel. The 323 driver that replaces it is named acd. You'll need to change 324 this in your configuration files. 325 326 Failure to do this will result in "ATAPI CD-ROMs not 327 configured" at boot time. 328 329 The floppy tape driver (ft) has been removed from the kernel, 330 with no replacement driver. 331 33219981202: 333 New groups from 19981201 commented out of mtree, so they 334 aren't strictly needed, but still a good idea to have. 335 33619981201: 337 New user/group added: bind. From src/etc/master.passwd and 338 src/etc/group: 339 % grep <newstuff> /usr/src/etc/group 340 bind:*:53: 341 % grep <newstuff> /usr/src/etc/master.passwd 342 tty:*:4:65533::0:0:Tty Sandbox:/:/sbin/nologin 343 kmem:*:5:65533::0:0:KMem Sandbox:/:/sbin/nologin 344 bind:*:53:53::0:0:Bind Sandbox:/:/sbin/nologin 345 34619981118: 347 PAM integrated into the tree. Requires new /etc/pam.conf file 348 to silence warnings from authentication programs (login, etc). 349 See src/etc/pam.conf for a sample. 350 351This file contains a list, in reverse chronologocal order, of major 352breakages in tracking -current. Not all things will be listed here, 353and it only starts on Novemeber 18, 1998. If you have an earlier 354version of FreeBSD, you are on your own to get to November 18, 1998. 355 356Please filter your entries through Warner (imp@village.org) so that 357the style, formatting, etc of this file can be maintained. 358 359$FreeBSD: head/UPDATING 51096 1999-09-08 18:34:31Z imp $ 360
