UPDATING revision 51033
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 619990905: 7 /var/cron/log has been moved to /var/log/cron to get all the 8 log files in one place. 919990831: 10 tn3270 has been removed from the based system and added as a port. 11 1219990830: 13 User-visible TCP timers are now expressed in units of 1ms, instead 14 of 500ms, so if you've customized any timer values under 15 ``net.inet.tcp'', multiply them by 500 to preserve TCP's behavior. 16 1719990828: 18 RCS Id tags changed to FreeBSD. This will cause huge cvsup 19 updates. 20 2119990821: 22 On 28-May-1999 libreadline was upgraded from readline-2.2 to 23 readline-4.0. At that time the shared library major version 24 number was bumped from "3" to "4". It has been deemed that 25 the interface change between readline-2.2 and readline-4.0 was 26 not suffient to warrant the version number bump. 27 28 Thus I have reverted it back to "3". You will need to perform 29 the below immediately before your next ``make world'': 30 cd /usr/lib 31 ls -l libreadline.so.4 32 (if you have /usr/lib/libreadline.so.4) 33 mv libreadline.so.4 libreadline.so.3 34 rm -f libreadline.so 35 ln -s libreadline.so.3 libreadline.so 36 3719990801: 38 Changes to the pccardd kernel interface require that you recompile 39 pccardd for new kernel. 40 4119980725: 42 The ipfw interface to the kernel has changed. You will need to 43 recompile ipfw programs for the new kernel. 44 4519990715: 46 The bpfilter device has been renamed to bpf. You will need to 47 change your config files in order to enable this in newer kernels. 48 4919990704: 50 src/contrib/sys/softupdates is moving to 51 src/sys/contrib/softupdates. Update your symbolic links/etc. 52 5319990702: 54 Major changes have been made to vinum and its interface. See 55 the man page (vinum(8)) for details. Look at the concat, 56 mirror and stripe commands, as well as the SIMPLIFIED 57 CONFIGURATION section. 58 5919990628: 60 Newsyslog.conf has had a minor, but potentially dangerous, 61 change to its username/group syntax. The old syntax was 62 user.group, while the new syntax is user:group. 63 6419990627: 65 Inetd wrapping default has changed. Please see the updated 66 man page for details. 67 6819990623: 69 Compaq Smart Raid driver committed as ida. 70 7119990622: 72 The second phase of syscons cleanup has happened. Some 73 functionality has been made optional. For details, see 74 http://www.freebsd.org/~yokota/sc_update-June.txt 75 Everyone will need to re-config(8) their kernels, but old 76 binaries will work with the new kernel. 77 7819990620: 79 IPFW uid/gid-based filtering support has been committed. This 80 breaks binary compatibility with previous copies of 81 ipfw(8). Any utilities using the ioctl()s of ipfw (especially 82 ipfw(8)) need to be recompiled with the newest headers 83 installed. 84 8519990618: 86 Inetd now wraps all stream-based services, including internals. 87 Syslog "severity" options are honoured. Installed syslog.conf 88 and hosts.allow should be checked. 89 9019990509: 91 Most of the problems with newbus have been corrected, but 92 it is still current and evolving. 93 94 libcam's ABI has changed. You must recompile the world and 95 any ports that use it. 96 9719990427: 98 Massive changes to SMP went into the tree that should speed 99 things up. However, if you experience problems with SMP 100 machines, you can back off to the PRE_SMP_VMSHARE tag in the 101 CVS repository (or run an MP kernel). 102 10319990420: 104 Pccardd and the pccard bus in general seem to be broken or 105 most people. Soren has patches to make it better for some, 106 but not all people. Work is underway to make it better for 107 all people. 108 10919990416: 110 new bus changes integrated into -current. Many problems were 111 initially reported, but most have been fixed. You'll need a 112 new config and to tweak your kernel config file the way that 113 GENERIC was tweaked. Keep a copy of your old kernel when 114 upgrading in case your new kernel doesn't work (and report the 115 breakage to current@freebsd.org). 116 117 As of 19990421 the remaining problems/quirks are 118 119 o sio no longer supports pnp nor pccard. This will be corrected, 120 but the new pccard code needs to be completed. 121 o Some of the sound drivers broke for some people. It seems 122 inconsistant as to who/what/when/where things broke. 123 o Duplicate device entries in your config do not work. Previously 124 they were silently ignored. psm0 seems to be the most common 125 duplicate choice, although some reports have come in from people 126 that wired their scsi disk entries. 127 o You must move the keyboard and mouse attachments from the 128 isa bus to the atkbdc bus. See GENERIC for details. 129 o Machines with multiple host-pci bridges (Intel 450NX) will not 130 probe the second pci bus. 131 o Some probe ordering may have changed, so device naming may change 132 with the new kernel. If you have multiple devices, please double 133 check to make sure they didn't move. This is especially true 134 for cards on different buses. 135 o The bus attachment for vga0 is always isa0 and never pci0 when 136 it is in fact a pci card. It is safe to ignore this. 137 o The format of the boot messages has changed (and is not 138 guaranteed to be constant for a while) so you may see this 139 in some shell scripts that diff dmesg from day to day as well 140 as scripts that parse dmesg output. 141 14219990414: 143 cc -aout sometimes has problems compiling with -g, remove -g 144 from those compilation units affected until this is corrected. 145 146 cc -aout has problems with producing some threaded libraries, 147 so make world -DWANT_AOUT is not functional at this time. 148 149 Since make world for a.out isn't functional, you cannot do 150 make aout-to-elf from a pre-egcs a.out system. To work around 151 this problem, make aout-to-elf using 3.1-stable first (or a 152 pre egcs -current) and then a simple make world will take you 153 the rest of the way with a -current source base. 154 15519990413: 156 Make -j works again for make world. As always, use it with 157 care, and be sure to try a make world w/o -j before reporting 158 problems (that is, know if the problem exists w/o -j before 159 reporting the problem with -j). 160 16119990413: 162 Note cc -aout, which had been broken since the conversion to 163 egcs, now supposedly works. If you have rebuilt things like 164 XFree86 a.out libraries, you should rebuild them again or 165 progams that use them, including netscape, will fail to work. 166 16719990409: 168 NOTE: New c++ compiler cannot be used with c++ binaries from 169 the old compiler and vice versa. 170 17119990408: 172 In recent days egcs has been imported into the tree. A number 173 of problems have been discussed in -current. Here is a highlight 174 of a few of the more common ones. With the exception of make 175 -j n, they have been claimed to have been fixed. 176 177 c++ is broken after make world: This is correct. Because we 178 changed compilers two make worlds are necessary to get C++ 179 working again. The code generated by the old compiler and new 180 compiler are not compatible, so things wind up being 181 undefined. 182 183 cpp is broken in make world: There was a window where cpp 184 would be built incorrectly. The fix for this is 185 cd src/gnu/usr.bin/cc 186 make clean 187 make all 188 make install 189 and this should correct your problems. See the -current 190 archives for a version of this that does moer cleaning. 191 192 Make -j n doesn't work. Work contiunes to make this work, 193 I've seen no reports of success as of April 7th. 194 19519990329: 196 Previously, one would define "NOAOUT" to keep from building 197 the legacy a.out bits. Now one would define "WANT_AOUT" to 198 build them. 199 20019990316: 201 The name of the old wd.c and atapi.c based CDROM driver has 202 been changed back to wcd. So update your config file to use 203 "device wcd" instead of "device acd". 204 20519990314: 206 For those of you using the VN device as a loadable module, 207 please be aware that the new VN device has been committed to 208 -4.x and cannot yet be used as a loadable module. This will 209 be fixed in the future. 210 21119990309: 212 New loader.rc mechanism. Please see src/sys/boot/README for 213 details. 214 21519990225: 216 struct proc size changed. Recompile kernel and the 217 usual suspects. Make world if in doubt. 218 21919990214: 220 The nlpt driver has changed names back to be the lpt driver. 221 See ppbus(4) or http://www.freebsd.org/~nsouch/ppbus.html 222 for proper configuration details. 223 22419990210: 225 The 'lpt' driver is now obsolete. Replace it with the 'nlpt' 226 driver and 'ppbus' controller combination. 227 22819990209: 229 New devstat API requires recompilation of libdevstat, systat, 230 iostat, vmstat and rpc.rstatd. A new kernel is also required. 231 make world + building a kernel should do all of this. Any 232 ports that use devstat need to be recompiled as well. 233 23419990125: 235 Linux threads options has gone away (they are now standard in 236 the FreeBSD kernel). A recompile of all libkvm using programs 237 is in order (or better yet a make world). 238 23919990122: 240 On or about this date there was a small window when the boot 241 blocks had some minor problems which seemed to force one to 242 edit /etc/fstab. This has been corrected, if you are seeing this 243 problem, please rebuild and reinstall your boot blocks. 244 24519990121: 246 Vinum has changed. The "vinum read" command has changed. For 247 updates, please see 248 249http://www.freebsd.org/cgi/getmsg.cgi?fetch=800363+0+current/freebsd-current 250 251 for details. 252 253 Matt Dillon committed a boatload of VM changes, for 254 information please see 255 256http://www.freebsd.org/cgi/getmsg.cgi?fetch=886676+0+current/freebsd-current 257 or 258http://www.freebsd.org/cgi/getmsg.cgi?fetch=827400+0+current/freebsd-current 259 260 for details. These changes will likely not impact anybody, 261 but large chagnes to the VM need at least a heads up. 262 26319990120: 264 Stable branch created. You might want to consider using this 265 branch. It is tagged with RELENG_3. 266 26719990119: 268 More work on the syscons driver has been committed. Since 269 files moved around, you will need to reconfigure your kernel, 270 and make clean; make depend before rebuilding the kernel. No 271 config file changes are needed. 272 27319990111: 274 New keyboard and video card drivers are introduced as the first 275 stage of console driver reorganization. You are required to 276 update the kernel configuration file and rebuild the kernel. 277 kbdcontrol, vidcontrol, and screen savers also need recompilation. 278 The instruction can be found in 279 280 http://www.freebsd.org/~yokota/sc_update.txt 281 282 It has notes on splash screen too. 283 28419990106: 285 Robert Nordier was kind enough to make this page to enable people to 286 install the new bootblocks: 287 288 http://www.freebsd.org/~rnordier/boot.txt 289 290 When updating to ELF, make sure that you have updated your 291 /etc/rc files which have different ldconfig invocations for 292 elf and aout. Otherwise things like X will stop working with 293 messages about being unable to find library files. The 294 mergemaster utility in ports/sysutils/mergemaster helps to 295 keep critical files like this in sync, and its use is 296 recommended. 297 29819990104: 299 Information about ELF day (see 19981230) can be found in 300 301 http://www.freebsd.org/~peter/elfday.html 302 303 about the upcoming change, its motivations and instructions 304 for doing the upgrade. 305 30619981230: 307 You should install new bootblocks now. The ELF kernel will 308 become default soon. In addition, you'll need to upgrade 309 your userland programs to ELF before then as well. Use 310 make aout-to-elf to upgrade your userland programs (old 311 a.out programs in, for example, /usr/local/bin will 312 continue to work, even after the upgrade). See src/Makefile 313 for more details. 314 31519981224: 316 The old wcd driver has been deleted from the kernel. The 317 driver that replaces it is named acd. You'll need to change 318 this in your configuration files. 319 320 Failure to do this will result in "ATAPI CD-ROMs not 321 configured" at boot time. 322 323 The floppy tape driver (ft) has been removed from the kernel, 324 with no replacement driver. 325 32619981202: 327 New groups from 19981201 commented out of mtree, so they 328 aren't strictly needed, but still a good idea to have. 329 33019981201: 331 New user/group added: bind. From src/etc/master.passwd and 332 src/etc/group: 333 % grep <newstuff> /usr/src/etc/group 334 bind:*:53: 335 % grep <newstuff> /usr/src/etc/master.passwd 336 tty:*:4:65533::0:0:Tty Sandbox:/:/sbin/nologin 337 kmem:*:5:65533::0:0:KMem Sandbox:/:/sbin/nologin 338 bind:*:53:53::0:0:Bind Sandbox:/:/sbin/nologin 339 34019981118: 341 PAM integrated into the tree. Requires new /etc/pam.conf file 342 to silence warnings from authentication programs (login, etc). 343 See src/etc/pam.conf for a sample. 344 345This file contains a list, in reverse chronologocal order, of major 346breakages in tracking -current. Not all things will be listed here, 347and it only starts on Novemeber 18, 1998. If you have an earlier 348version of FreeBSD, you are on your own to get to November 18, 1998. 349 350Please filter your entries through Warner (imp@village.org) so that 351the style, formatting, etc of this file can be maintained. 352 353$FreeBSD: head/UPDATING 51033 1999-09-06 20:10:27Z n_hibma $ 354
