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 619991015: 7 PCCARD has been updated to attach pcic to the isa bus. Therefore 8 you will need to modify kernel config files that have pcic/card 9 in them as follows: 10 controller pcic0 at isa? 11 controller pcic1 at isa? 12 controller card0 13 1419990929: 15 The sigset_t datatype has been changed from an integral type 16 to a compound type and can hold 128 signals. Syscalls directly 17 or indirectly using the new sigset_t have been added as to 18 maintain compatible with existing binaries. A new kernel must 19 be made and installed and booted with before a make world can 20 be done. 21 2219990919: 23 New jail syscall format requires recompilation of jail(8) with 24 fresh headers installed (or a make world will do it for you). 25 2619990914: 27 Matt Dillon checked in many vm related things and sent a heads up 28 to -current urging caution and to report vm problems to him. 29 As of the 19th, no killer problems have been reported, but you 30 have been warned. 31 3219990908: 33 The new miibus has been added to the system. If you are using 34 the dm, rl, sf, sis, ste, tl, wb or xl drivers, you need to 35 add "controller miibus0" to your config file. 36 3719990905: 38 /var/cron/log has been moved to /var/log/cron to get all the 39 log files in one place. 40 4119990831: 42 tn3270 has been removed from the based system and added as a port. 43 4419990830: 45 User-visible TCP timers are now expressed in units of 1ms, instead 46 of 500ms, so if you've customized any timer values under 47 ``net.inet.tcp'', multiply them by 500 to preserve TCP's behavior. 48 4919990828: 50 RCS Id tags changed to FreeBSD. This will cause huge cvsup 51 updates. 52 5319990821: 54 On 28-May-1999 libreadline was upgraded from readline-2.2 to 55 readline-4.0. At that time the shared library major version 56 number was bumped from "3" to "4". It has been deemed that 57 the interface change between readline-2.2 and readline-4.0 was 58 not suffient to warrant the version number bump. 59 60 Thus I have reverted it back to "3". You will need to perform 61 the below immediately before your next ``make world'': 62 cd /usr/lib 63 ls -l libreadline.so.4 64 (if you have /usr/lib/libreadline.so.4) 65 mv libreadline.so.4 libreadline.so.3 66 rm -f libreadline.so 67 ln -s libreadline.so.3 libreadline.so 68 6919990801: 70 Changes to the pccardd kernel interface require that you recompile 71 pccardd for new kernel. 72 7319980725: 74 The ipfw interface to the kernel has changed. You will need to 75 recompile ipfw programs for the new kernel. 76 7719990715: 78 The bpfilter device has been renamed to bpf. You will need to 79 change your config files in order to enable this in newer kernels. 80 8119990704: 82 src/contrib/sys/softupdates is moving to 83 src/sys/contrib/softupdates. Update your symbolic links/etc. 84 8519990702: 86 Major changes have been made to vinum and its interface. See 87 the man page (vinum(8)) for details. Look at the concat, 88 mirror and stripe commands, as well as the SIMPLIFIED 89 CONFIGURATION section. 90 9119990628: 92 Newsyslog.conf has had a minor, but potentially dangerous, 93 change to its username/group syntax. The old syntax was 94 user.group, while the new syntax is user:group. 95 9619990627: 97 Inetd wrapping default has changed. Please see the updated 98 man page for details. 99 10019990623: 101 Compaq Smart Raid driver committed as ida. 102 10319990622: 104 The second phase of syscons cleanup has happened. Some 105 functionality has been made optional. For details, see 106 http://www.freebsd.org/~yokota/sc_update-June.txt 107 Everyone will need to re-config(8) their kernels, but old 108 binaries will work with the new kernel. 109 11019990620: 111 IPFW uid/gid-based filtering support has been committed. This 112 breaks binary compatibility with previous copies of 113 ipfw(8). Any utilities using the ioctl()s of ipfw (especially 114 ipfw(8)) need to be recompiled with the newest headers 115 installed. 116 11719990618: 118 Inetd now wraps all stream-based services, including internals. 119 Syslog "severity" options are honoured. Installed syslog.conf 120 and hosts.allow should be checked. 121 12219990509: 123 Most of the problems with newbus have been corrected, but 124 it is still current and evolving. 125 126 libcam's ABI has changed. You must recompile the world and 127 any ports that use it. 128 12919990427: 130 Massive changes to SMP went into the tree that should speed 131 things up. However, if you experience problems with SMP 132 machines, you can back off to the PRE_SMP_VMSHARE tag in the 133 CVS repository (or run an MP kernel). 134 13519990420: 136 Pccardd and the pccard bus in general seem to be broken or 137 most people. Soren has patches to make it better for some, 138 but not all people. Work is underway to make it better for 139 all people. 140 14119990416: 142 new bus changes integrated into -current. Many problems were 143 initially reported, but most have been fixed. You'll need a 144 new config and to tweak your kernel config file the way that 145 GENERIC was tweaked. Keep a copy of your old kernel when 146 upgrading in case your new kernel doesn't work (and report the 147 breakage to current@freebsd.org). 148 149 As of 19990421 the remaining problems/quirks are 150 151 o sio no longer supports pnp nor pccard. This will be corrected, 152 but the new pccard code needs to be completed. 153 o Some of the sound drivers broke for some people. It seems 154 inconsistant as to who/what/when/where things broke. 155 o Duplicate device entries in your config do not work. Previously 156 they were silently ignored. psm0 seems to be the most common 157 duplicate choice, although some reports have come in from people 158 that wired their scsi disk entries. 159 o You must move the keyboard and mouse attachments from the 160 isa bus to the atkbdc bus. See GENERIC for details. 161 o Machines with multiple host-pci bridges (Intel 450NX) will not 162 probe the second pci bus. 163 o Some probe ordering may have changed, so device naming may change 164 with the new kernel. If you have multiple devices, please double 165 check to make sure they didn't move. This is especially true 166 for cards on different buses. 167 o The bus attachment for vga0 is always isa0 and never pci0 when 168 it is in fact a pci card. It is safe to ignore this. 169 o The format of the boot messages has changed (and is not 170 guaranteed to be constant for a while) so you may see this 171 in some shell scripts that diff dmesg from day to day as well 172 as scripts that parse dmesg output. 173 17419990414: 175 cc -aout sometimes has problems compiling with -g, remove -g 176 from those compilation units affected until this is corrected. 177 178 cc -aout has problems with producing some threaded libraries, 179 so make world -DWANT_AOUT is not functional at this time. 180 181 Since make world for a.out isn't functional, you cannot do 182 make aout-to-elf from a pre-egcs a.out system. To work around 183 this problem, make aout-to-elf using 3.1-stable first (or a 184 pre egcs -current) and then a simple make world will take you 185 the rest of the way with a -current source base. 186 18719990413: 188 Make -j works again for make world. As always, use it with 189 care, and be sure to try a make world w/o -j before reporting 190 problems (that is, know if the problem exists w/o -j before 191 reporting the problem with -j). 192 19319990413: 194 Note cc -aout, which had been broken since the conversion to 195 egcs, now supposedly works. If you have rebuilt things like 196 XFree86 a.out libraries, you should rebuild them again or 197 progams that use them, including netscape, will fail to work. 198 19919990409: 200 NOTE: New c++ compiler cannot be used with c++ binaries from 201 the old compiler and vice versa. 202 20319990408: 204 In recent days egcs has been imported into the tree. A number 205 of problems have been discussed in -current. Here is a highlight 206 of a few of the more common ones. With the exception of make 207 -j n, they have been claimed to have been fixed. 208 209 c++ is broken after make world: This is correct. Because we 210 changed compilers two make worlds are necessary to get C++ 211 working again. The code generated by the old compiler and new 212 compiler are not compatible, so things wind up being 213 undefined. 214 215 cpp is broken in make world: There was a window where cpp 216 would be built incorrectly. The fix for this is 217 cd src/gnu/usr.bin/cc 218 make clean 219 make all 220 make install 221 and this should correct your problems. See the -current 222 archives for a version of this that does moer cleaning. 223 224 Make -j n doesn't work. Work contiunes to make this work, 225 I've seen no reports of success as of April 7th. 226 22719990329: 228 Previously, one would define "NOAOUT" to keep from building 229 the legacy a.out bits. Now one would define "WANT_AOUT" to 230 build them. 231 23219990316: 233 The name of the old wd.c and atapi.c based CDROM driver has 234 been changed back to wcd. So update your config file to use 235 "device wcd" instead of "device acd". 236 23719990314: 238 For those of you using the VN device as a loadable module, 239 please be aware that the new VN device has been committed to 240 -4.x and cannot yet be used as a loadable module. This will 241 be fixed in the future. 242 24319990309: 244 New loader.rc mechanism. Please see src/sys/boot/README for 245 details. 246 24719990225: 248 struct proc size changed. Recompile kernel and the 249 usual suspects. Make world if in doubt. 250 25119990214: 252 The nlpt driver has changed names back to be the lpt driver. 253 See ppbus(4) or http://www.freebsd.org/~nsouch/ppbus.html 254 for proper configuration details. 255 25619990210: 257 The 'lpt' driver is now obsolete. Replace it with the 'nlpt' 258 driver and 'ppbus' controller combination. 259 26019990209: 261 New devstat API requires recompilation of libdevstat, systat, 262 iostat, vmstat and rpc.rstatd. A new kernel is also required. 263 make world + building a kernel should do all of this. Any 264 ports that use devstat need to be recompiled as well. 265 26619990125: 267 Linux threads options has gone away (they are now standard in 268 the FreeBSD kernel). A recompile of all libkvm using programs 269 is in order (or better yet a make world). 270 27119990122: 272 On or about this date there was a small window when the boot 273 blocks had some minor problems which seemed to force one to 274 edit /etc/fstab. This has been corrected, if you are seeing this 275 problem, please rebuild and reinstall your boot blocks. 276 27719990121: 278 Vinum has changed. The "vinum read" command has changed. For 279 updates, please see 280 281http://www.freebsd.org/cgi/getmsg.cgi?fetch=800363+0+current/freebsd-current 282 283 for details. 284 285 Matt Dillon committed a boatload of VM changes, for 286 information please see 287 288http://www.freebsd.org/cgi/getmsg.cgi?fetch=886676+0+current/freebsd-current 289 or 290http://www.freebsd.org/cgi/getmsg.cgi?fetch=827400+0+current/freebsd-current 291 292 for details. These changes will likely not impact anybody, 293 but large chagnes to the VM need at least a heads up. 294 29519990120: 296 Stable branch created. You might want to consider using this 297 branch. It is tagged with RELENG_3. 298 29919990119: 300 More work on the syscons driver has been committed. Since 301 files moved around, you will need to reconfigure your kernel, 302 and make clean; make depend before rebuilding the kernel. No 303 config file changes are needed. 304 30519990111: 306 New keyboard and video card drivers are introduced as the first 307 stage of console driver reorganization. You are required to 308 update the kernel configuration file and rebuild the kernel. 309 kbdcontrol, vidcontrol, and screen savers also need recompilation. 310 The instruction can be found in 311 312 http://www.freebsd.org/~yokota/sc_update.txt 313 314 It has notes on splash screen too. 315 31619990106: 317 Robert Nordier was kind enough to make this page to enable people to 318 install the new bootblocks: 319 320 http://www.freebsd.org/~rnordier/boot.txt 321 322 When updating to ELF, make sure that you have updated your 323 /etc/rc files which have different ldconfig invocations for 324 elf and aout. Otherwise things like X will stop working with 325 messages about being unable to find library files. The 326 mergemaster utility in ports/sysutils/mergemaster helps to 327 keep critical files like this in sync, and its use is 328 recommended. 329 33019990104: 331 Information about ELF day (see 19981230) can be found in 332 333 http://www.freebsd.org/~peter/elfday.html 334 335 about the upcoming change, its motivations and instructions 336 for doing the upgrade. 337 33819981230: 339 You should install new bootblocks now. The ELF kernel will 340 become default soon. In addition, you'll need to upgrade 341 your userland programs to ELF before then as well. Use 342 make aout-to-elf to upgrade your userland programs (old 343 a.out programs in, for example, /usr/local/bin will 344 continue to work, even after the upgrade). See src/Makefile 345 for more details. 346 34719981224: 348 The old wcd driver has been deleted from the kernel. The 349 driver that replaces it is named acd. You'll need to change 350 this in your configuration files. 351 352 Failure to do this will result in "ATAPI CD-ROMs not 353 configured" at boot time. 354 355 The floppy tape driver (ft) has been removed from the kernel, 356 with no replacement driver. 357 35819981202: 359 New groups from 19981201 commented out of mtree, so they 360 aren't strictly needed, but still a good idea to have. 361 36219981201: 363 New user/group added: bind. From src/etc/master.passwd and 364 src/etc/group: 365 % grep <newstuff> /usr/src/etc/group 366 bind:*:53: 367 % grep <newstuff> /usr/src/etc/master.passwd 368 tty:*:4:65533::0:0:Tty Sandbox:/:/sbin/nologin 369 kmem:*:5:65533::0:0:KMem Sandbox:/:/sbin/nologin 370 bind:*:53:53::0:0:Bind Sandbox:/:/sbin/nologin 371 37219981118: 373 PAM integrated into the tree. Requires new /etc/pam.conf file 374 to silence warnings from authentication programs (login, etc). 375 See src/etc/pam.conf for a sample. 376 377This file contains a list, in reverse chronologocal order, of major 378breakages in tracking -current. Not all things will be listed here, 379and it only starts on November 18, 1998. If you have an earlier 380version of FreeBSD, you are on your own to get to November 18, 1998. 381 382Please filter your entries through Warner (imp@village.org) so that 383the style, formatting, etc of this file can be maintained. 384 385$FreeBSD$ 386
