UPDATING revision 49353
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 1019990704: 11 src/contrib/sys/softupdates is moving to 12 src/sys/contrib/softupdates. Update your symbolic links/etc. 13 1419990702: 15 Major changes have been made to vinum and its interface. See 16 the man page (vinum(8)) for details. Look at the concat, 17 mirror and stripe commands, as well as the SIMPLIFIED 18 CONFIGURATION section. 19 2019990628: 21 Newsyslog.conf has had a minor, but potentially dangerous, 22 change to its username/group syntax. The old syntax was 23 user.group, while the new syntax is user:group. 24 2519990627: 26 Inetd wrapping default has changed. Please see the updated 27 man page for details. 28 2919990623: 30 Compaq Smart Raid driver committed as ida. 31 3219990622: 33 The second phase of syscons cleanup has happened. Some 34 functionality has been made optional. For details, see 35 http://www.freebsd.org/~yokota/sc_update-June.txt 36 Everyone will need to re-config(8) their kernels, but old 37 binaries will work with the new kernel. 38 3919990620: 40 IPFW uid/gid-based filtering support has been committed. This 41 breaks binary compatibility with previous copies of 42 ipfw(8). Any utilities using the ioctl()s of ipfw (especially 43 ipfw(8)) need to be recompiled with the newest headers 44 installed. 45 4619990618: 47 Inetd now wraps all stream-based services, including internals. 48 Syslog "severity" options are honoured. Installed syslog.conf 49 and hosts.allow should be checked. 50 5119990509: 52 Most of the problems with newbus have been corrected, but 53 it is still current and evolving. 54 55 libcam's ABI has changed. You must recompile the world and 56 any ports that use it. 57 5819990427: 59 Massive changes to SMP went into the tree that should speed 60 things up. However, if you experience problems with SMP 61 machines, you can back off to the PRE_SMP_VMSHARE tag in the 62 CVS repository (or run an MP kernel). 63 6419990420: 65 Pccardd and the pccard bus in general seem to be broken or 66 most people. Soren has patches to make it better for some, 67 but not all people. Work is underway to make it better for 68 all people. 69 7019990416: 71 new bus changes integrated into -current. Many problems were 72 initially reported, but most have been fixed. You'll need a 73 new config and to tweak your kernel config file the way that 74 GENERIC was tweaked. Keep a copy of your old kernel when 75 upgrading in case your new kernel doesn't work (and report the 76 breakage to current@freebsd.org). 77 78 As of 19990421 the remaining problems/quirks are 79 80 o sio no longer supports pnp nor pccard. This will be corrected, 81 but the new pccard code needs to be completed. 82 o Some of the sound drivers broke for some people. It seems 83 inconsistant as to who/what/when/where things broke. 84 o Duplicate device entries in your config do not work. Previously 85 they were silently ignored. psm0 seems to be the most common 86 duplicate choice, although some reports have come in from people 87 that wired their scsi disk entries. 88 o You must move the keyboard and mouse attachments from the 89 isa bus to the atkbdc bus. See GENERIC for details. 90 o Machines with multiple host-pci bridges (Intel 450NX) will not 91 probe the second pci bus. 92 o Some probe ordering may have changed, so device naming may change 93 with the new kernel. If you have multiple devices, please double 94 check to make sure they didn't move. This is especially true 95 for cards on different buses. 96 o The bus attachment for vga0 is always isa0 and never pci0 when 97 it is in fact a pci card. It is safe to ignore this. 98 o The format of the boot messages has changed (and is not 99 guaranteed to be constant for a while) so you may see this 100 in some shell scripts that diff dmesg from day to day as well 101 as scripts that parse dmesg output. 102 10319990414: 104 cc -aout sometimes has problems compiling with -g, remove -g 105 from those compilation units affected until this is corrected. 106 107 cc -aout has problems with producing some threaded libraries, 108 so make world -DWANT_AOUT is not functional at this time. 109 110 Since make world for a.out isn't functional, you cannot do 111 make aout-to-elf from a pre-egcs a.out system. To work around 112 this problem, make aout-to-elf using 3.1-stable first (or a 113 pre egcs -current) and then a simple make world will take you 114 the rest of the way with a -current source base. 115 11619990413: 117 Make -j works again for make world. As always, use it with 118 care, and be sure to try a make world w/o -j before reporting 119 problems (that is, know if the problem exists w/o -j before 120 reporting the problem with -j). 121 12219990413: 123 Note cc -aout, which had been broken since the conversion to 124 egcs, now supposedly works. If you have rebuilt things like 125 XFree86 a.out libraries, you should rebuild them again or 126 progams that use them, including netscape, will fail to work. 127 12819990409: 129 NOTE: New c++ compiler cannot be used with c++ binaries from 130 the old compiler and vice versa. 131 13219990408: 133 In recent days egcs has been imported into the tree. A number 134 of problems have been discussed in -current. Here is a highlight 135 of a few of the more common ones. With the exception of make 136 -j n, they have been claimed to have been fixed. 137 138 c++ is broken after make world: This is correct. Because we 139 changed compilers two make worlds are necessary to get C++ 140 working again. The code generated by the old compiler and new 141 compiler are not compatible, so things wind up being 142 undefined. 143 144 cpp is broken in make world: There was a window where cpp 145 would be built incorrectly. The fix for this is 146 cd src/gnu/usr.bin/cc 147 make clean 148 make all 149 make install 150 and this should correct your problems. See the -current 151 archives for a version of this that does moer cleaning. 152 153 Make -j n doesn't work. Work contiunes to make this work, 154 I've seen no reports of success as of April 7th. 155 15619990329: 157 Previously, one would define "NOAOUT" to keep from building 158 the legacy a.out bits. Now one would define "WANT_AOUT" to 159 build them. 160 16119990316: 162 The name of the old wd.c and atapi.c based CDROM driver has 163 been changed back to wcd. So update your config file to use 164 "device wcd" instead of "device acd". 165 16619990314: 167 For those of you using the VN device as a loadable module, 168 please be aware that the new VN device has been committed to 169 -4.x and cannot yet be used as a loadable module. This will 170 be fixed in the future. 171 17219990309: 173 New loader.rc mechanism. Please see src/sys/boot/README for 174 details. 175 17619990225: 177 struct proc size changed. Recompile kernel and the 178 usual suspects. Make world if in doubt. 179 18019990214: 181 The nlpt driver has changed names back to be the lpt driver. 182 See ppbus(4) or http://www.freebsd.org/~nsouch/ppbus.html 183 for proper configuration details. 184 18519990210: 186 The 'lpt' driver is now obsolete. Replace it with the 'nlpt' 187 driver and 'ppbus' controller combination. 188 18919990209: 190 New devstat API requires recompilation of libdevstat, systat, 191 iostat, vmstat and rpc.rstatd. A new kernel is also required. 192 make world + building a kernel should do all of this. Any 193 ports that use devstat need to be recompiled as well. 194 19519990125: 196 Linux threads options has gone away (they are now standard in 197 the FreeBSD kernel). A recompile of all libkvm using programs 198 is in order (or better yet a make world). 199 20019990122: 201 On or about this date there was a small window when the boot 202 blocks had some minor problems which seemed to force one to 203 edit /etc/fstab. This has been corrected, if you are seeing this 204 problem, please rebuild and reinstall your boot blocks. 205 20619990121: 207 Vinum has changed. The "vinum read" command has changed. For 208 updates, please see 209 210http://www.freebsd.org/cgi/getmsg.cgi?fetch=800363+0+current/freebsd-current 211 212 for details. 213 214 Matt Dillon committed a boatload of VM changes, for 215 information please see 216 217http://www.freebsd.org/cgi/getmsg.cgi?fetch=886676+0+current/freebsd-current 218 or 219http://www.freebsd.org/cgi/getmsg.cgi?fetch=827400+0+current/freebsd-current 220 221 for details. These changes will likely not impact anybody, 222 but large chagnes to the VM need at least a heads up. 223 22419990120: 225 Stable branch created. You might want to consider using this 226 branch. It is tagged with RELENG_3. 227 22819990119: 229 More work on the syscons driver has been committed. Since 230 files moved around, you will need to reconfigure your kernel, 231 and make clean; make depend before rebuilding the kernel. No 232 config file changes are needed. 233 23419990111: 235 New keyboard and video card drivers are introduced as the first 236 stage of console driver reorganization. You are required to 237 update the kernel configuration file and rebuild the kernel. 238 kbdcontrol, vidcontrol, and screen savers also need recompilation. 239 The instruction can be found in 240 241 http://www.freebsd.org/~yokota/sc_update.txt 242 243 It has notes on splash screen too. 244 24519990106: 246 Robert Nordier was kind enough to make this page to enable people to 247 install the new bootblocks: 248 249 http://www.freebsd.org/~rnordier/boot.txt 250 251 When updating to ELF, make sure that you have updated your 252 /etc/rc files which have different ldconfig invocations for 253 elf and aout. Otherwise things like X will stop working with 254 messages about being unable to find library files. The 255 mergemaster utility in ports/sysutils/mergemaster helps to 256 keep critical files like this in sync, and its use is 257 recommended. 258 25919990104: 260 Information about ELF day (see 19981230) can be found in 261 262 http://www.freebsd.org/~peter/elfday.html 263 264 about the upcoming change, its motivations and instructions 265 for doing the upgrade. 266 26719981230: 268 You should install new bootblocks now. The ELF kernel will 269 become default soon. In addition, you'll need to upgrade 270 your userland programs to ELF before then as well. Use 271 make aout-to-elf to upgrade your userland programs (old 272 a.out programs in, for example, /usr/local/bin will 273 continue to work, even after the upgrade). See src/Makefile 274 for more details. 275 27619981224: 277 The old wcd driver has been deleted from the kernel. The 278 driver that replaces it is named acd. You'll need to change 279 this in your configuration files. 280 281 Failure to do this will result in "ATAPI CD-ROMs not 282 configured" at boot time. 283 284 The floppy tape driver (ft) has been removed from the kernel, 285 with no replacement driver. 286 28719981202: 288 New groups from 19981201 commented out of mtree, so they 289 aren't strictly needed, but still a good idea to have. 290 29119981201: 292 New user/group added: bind. From src/etc/master.passwd and 293 src/etc/group: 294 % grep <newstuff> /usr/src/etc/group 295 bind:*:53: 296 % grep <newstuff> /usr/src/etc/master.passwd 297 tty:*:4:65533::0:0:Tty Sandbox:/:/sbin/nologin 298 kmem:*:5:65533::0:0:KMem Sandbox:/:/sbin/nologin 299 bind:*:53:53::0:0:Bind Sandbox:/:/sbin/nologin 300 30119981118: 302 PAM integrated into the tree. Requires new /etc/pam.conf file 303 to silence warnings from authentication programs (login, etc). 304 See src/etc/pam.conf for a sample. 305 306This file contains a list, in reverse chronologocal order, of major 307breakages in tracking -current. Not all things will be listed here, 308and it only starts on Novemeber 18, 1998. If you have an earlier 309version of FreeBSD, you are on your own to get to November 18, 1998. 310 311Please filter your entries through Warner (imp@village.org) so that 312the style, formatting, etc of this file can be maintained. 313 314$Id: UPDATING,v 1.38 1999/07/07 04:28:48 imp Exp $ 315
