UPDATING revision 70621
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. For commonly 5done items, please see the end of the file. Search for 'COMMON 6ITEMS:' 7 820010101: 9 ex and vi were broken by some changes to sys/queue.h. If you 10 have a bad vi, you will see make buildworld fail with a core 11 dump while building termcap. You can work around this problem 12 by adding -k to your make buildworld. This will cause the 13 build to complete and install a new vi. Once that's done, you 14 can rebuild again without the -k to pick up anything that 15 might have been ignored by the -k option. 16 17 Others have suggested that you can just rebuild libc if your 18 vi/ex is dynamically linked, but I've not received any reports 19 of this working. 20 2120001218: 22 Linksys Fast Ethernet PCCARD cards supported by the ed driver 23 now require the addition of flag 0x80000 to their config line 24 in pccard.conf(5). This flag is not optional. These Linksys 25 cards will not be recognized without it. 26 2720001205: 28 Important new FreeBSD-version stuff: PAM support has been worked 29 in, partially from the "Unix" OpenSSH version. This requires 30 adding the following in pam.conf: 31 32 sshd auth sufficient pam_skey.so 33 sshd auth required pam_unix.so try_first_pass 34 sshd session required pam_permit.so 35 3620001031: 37 cvs updated to 1.11. 38 3920001020: 40 The random device needs more entropy, so you need to make sure 41 that you've run mergemaster to get a /etc/rc which will seed 42 /dev/random. If you don't and the system hangs after ldconfig, 43 then banging on the keyboard randomly until it unhangs is one 44 workaround. 45 4620001010: 47 ****************************** WARNING ****************************** 48 Sendmail has been updated. 49 ****************************** WARNING ****************************** 50 o mail.local(8) is no longer installed as a set-user-id binary. 51 o sendmail(8) is now built with STARTTLS support unless NO_OPENSSL 52 is set. 53 o The default /etc/mail/sendmail.cf disables the SMTP EXPN and VRFY 54 commands. 55 o Now using sendmail's version of vacation(1). 56 o The sendmail cf building tools (contrib/sendmail/cf) are installed 57 in /usr/share/sendmail/cf. 58 o sendmail.cw changed to local-host-names 59 60 More details can be found at 61 http://people.freebsd.org/~imp/UPDATING/sendmail-20001010 62 6320001009: 64 The ports tree's new layout is in place. Be sure to update 65 your entire ports tree, or you will have problems. 66 6720001006: 68 The perl build procedure no longer installs miniperl, nor uses 69 the installed miniperl. It is recommended that you delete 70 /usr/bin/miniperl. 71 7220001005: 73 This weekend the ports tree will be updated to a new layout. 74 It will be in an inconsistent state until noted in the UPDATING 75 file, or with asami-san's message to the relevant mailing 76 lists. With this new layout, you'll need to update the whole 77 tree for anything to work. 78 7920000928: 80 There was a change in the passwd format. Need more information. 81 8220000916: 83 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken 84 place. Please update boot loader (not the boot blocks) at the 85 same time as your kernel. 86 8720000914: 88 The new pmtimer device is necessary for laptops. Failure to 89 include the device will cause suspended laptops losing time 90 when they resume. Include 91 device pmtimer 92 in your config file and 93 hint.pmtimer.0.at="isa" 94 to your /boot/device.hints file. 95 9620000911: 97 The random device has been turned into a (pseudo-)device, 98 rather than an option. The supplied kernel config files have 99 been updated. You will need to do something similar in your 100 own kernel config file. 101 Remove: 102 options RANDOMDEV 103 Add: 104 device random 105 If you prefer to load the loadable module, you need to do 106 nothing. 107 10820000909: 109 The random device module has been renamed from randomdev.ko to 110 random.ko. You will need to edit your /boot/loader.conf to 111 reflect this if you load this module at boot time. 112 The line should read: 113 random_load="YES" 114 11520000907: 116 The SMPNG commit has happened. It should work, but if it 117 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely 118 to be a variety of minor issues. Please see 20000905 to make 119 sure you don't have model loading problems which might at 120 first blush appear related to SMP. 121 12220000906: 123 nsswitch has been imported from NetBSD. Among other things, 124 this means that /etc/host.conf is no longer used. See 125 nsswitch.conf(5) instead. Note that at boot time rc.network 126 will attempt to produce a new nsswitch.conf file for you if you 127 don't have one, and you have host.conf. 128 12920000905: 130 The ucred structure changed size. This breaks the interface 131 that mountd uses. Trying to use an older mountd with a newer 132 kernel guarantees a panic. This means that you need to use 133 kernels newer than today only with matching mountd, but you 134 needed to do that anyway with the boot loader changes. 135 13620000905: 137 The boot loader has been updated. The new default kernel is 138 now /boot/kernel/kernel.ko. The new default module location 139 is /boot/kernel. 140 141 You *MUST* upgrade your boot loader and kernel at the same time. 142 The easiest way to do this is to do the buildworld/buildkernel/ 143 installkernel/installworld dance. 144 145 Furthermore, you are urged to delete your old /modules directory 146 before booting the new kernel, since kldload will find stale 147 modules in that directory instead of finding them in the correct 148 path, /boot/kernel. The most common complaint that this cures 149 is that the linux module crashes your machine after the update. 150 151 if [ ! -d /boot/kernel.old ]; then 152 mv /modules.old /boot/kernel.old 153 chflags noschg /kernel.old 154 mv /kernel.old /boot/kernel.old/kernel.ko 155 chflags schg /boot/kernel.old/kernel.ko 156 fi 157 15820000904: 159 A new issue with the sendmail upgrade has come to light. 160 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will 161 incorrectly install the default aliases in /etc/mail rather than 162 move the old one from /etc. So you'll need to manually move the 163 file, create a symbolic link, remove the old /etc/aliases.db and 164 run newaliases. For safety sake, you should stop sendmail 165 while doing this and run the upgrade when locally sourced email 166 is not likely to be generated. 167 16820000825: 169 /boot/device.hints is now required for installkernel to 170 succeed. You should copy GENERIC.hints for your architecture 171 into /boot/device.hints. If and only if you compile hints 172 into your kernel, then this file may be empty. Please note, 173 if you have an empty or missing /boot/device.hints file and 174 you neglected to compile hints into your kernel, no boot 175 messages will appear after the boot loader tries to start the 176 kernel. 177 17820000821: 179 If you do NOT have ``options RANDOMDEV'' in your kernel and 180 you DO want the random device then add randomdev_load="YES" to 181 /boot/loader.conf. 182 18320000812: 184 suidperl is now always built and installed on the system, but 185 with permissions of 511. If you have applications that use 186 this program, you are now required to add ENABLE_SUIDPERL=true 187 to /etc/make.conf. If you forget to do this, 188 chmod 4511 /usr/bin/suidperl 189 will fix this until the next build. 190 19120000812: 192 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more 193 visible changes that may immediately affect your configuration 194 include: 195 - New default file locations from src/contrib/sendmail/cf/README 196 - newaliases limited to root and trusted users 197 - MSA port (587) turned on by default 198 - New queue file naming system so can't go from 8.11 -> 8.9 199 - FEATURE(`rbl') renamed to FEATURE(`dnsbl') 200 - FEATURE(`nullclient') is more full featured 201 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial' 202 - mail.local FreeBSD-only -b option changed to -B 203 - See src/contrib/sendmail/RELEASE_NOTES for more info 204 20520000810: 206 suidperl (aka sperl) is no longer build by default. You must 207 specifically define BUILD_SUIDPERL to "true" for it to be build. 208 Furthermore, we recommend that you remove /usr/bin/sperl* and 209 /usr/bin/suidperl files from your system unless you have a 210 specific use for it. 211 21220000729: 213 Networking defaults have been tightened. Anybody upgrading 214 /etc/defaults/rc.conf needs to add the following lines to 215 /etc/rc.conf if they want to have the same setup 216 afterwards (unless the variables already are set, of course): 217 # Enable network daemons for user convenience. 218 inetd_enable="YES" 219 portmap_enable="YES" 220 sendmail_enable="YES" 221 22220000728: 223 If you have null_load="YES" in your /boot/loader.conf, you 224 will need to change that to nullfs_load="YES". 225 22620000728: 227 The "installkernel" target has changed slightly. Now even if 228 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL' 229 it will install the MYKERNEL file (built with the buildkernel 230 target) as /kernel rather than /MYKERNEL. Those who have 231 updated their /boot/loader.conf files to point to /MYKERNEL 232 should remove that entry or perform manual rename of /kernel 233 to /MYKERNEL. 234 23520000711: 236 If you use CVSUP or CTM to get CVS trees, AND you used to get 237 the old crypto files from internat.freebsd.org AND you check 238 out files from the CVS tree with the cvs command, please read 239 http://people.freebsd.org/~imp/internat.txt 240 for details on potential problems that you might have and how 241 to get around them. 242 243 If you are merely a mirror, or don't answer yes to each of the 244 clauses above, you needn't worry. 245 24620000711: 247 /etc/security has been updated to print the inode number of 248 setuid programs that have changed. You will see a large spike 249 in the number of changed programs the first time when you run 250 mergemaster to get a new /etc/security. 251 25220000710: 253 /dev/random now has good entropy collection (from the keyboard 254 and sysmouse drivers). Please ensure that either `options 255 RANDOMDEV' is present in your kernel config file or that 256 `randomdev_load="YES"' is in your /boot/loader.conf. If you do 257 not have the /dev/random driver, OpenSSL (and consequently 258 lots of crypto tools (like SSH)) will fail with strange 259 errors. (see below, 20000624). 260 261 FreeBSD-current is safe again to run Crypto. 262 26320000709: 264 phk made the malloc default options AJ. This may slow things 265 down and uncover other latent bugs in the code. If you need to 266 run at full speed, you can disable this by doing the following: 267 ln -s aj /etc/malloc.conf 268 26920000706: 270 libftpio's version was accidentally bumped a few days ago. This 271 has been corrected. You may need to remove /usr/lib/libftpio.so.6 272 before doing your next buildworld/installworld pair. It certainly 273 won't hurt to remove it before the update procedure. It will 274 break fetch until a new one is built, but ftp can be used in the 275 interim if needed. 276 27720000705: 278 The crypto packages have changed for the cvsup. This has been done 279 in a backward compatible way, but the old packages will go away at 280 some point in the future. Look at /usr/share/examples/cvsup for 281 details. 282 28320000704: 284 With the new sys/modules/sound/drivers/*, you will need to 285 set SYSDIR until you do an installworld after July 7th. 286 28720000704: 288 rc.shutdown and rc will now call the rc.d scripts with start 289 or stop. This may cause some harmless warnings from older 290 rc.d scripts that haven't been updated. 291 29220000630: 293 The libfetch based version of fetch has gone into the tree. 294 Minor problems may result on some of the less popular sites, 295 which should be reported to des@freebsd.org. 296 29720000625: 298 From approximately this date forward, one must have the crypto 299 system installed in order to build the system and kernel. 300 While not technically strictly true, one should treat it as 301 required and grab the crypto bits. If you are grabbing CVS 302 trees, src-all and cvs-crypto should be treated as if they 303 were required. You should check with the latest collections 304 to make sure that these haven't changed. 305 30620000624: 307 Mark Murray just committed the first parts of a cleanup of 308 /dev/zero, et al. This is also cleaning up /dev/random. 309 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD 310 -CURRENT FROM THIS POINT FORWARD for cryptographic services 311 until Mark can merge in the fixes to this work in progress. 312 openssh and openssl should not be used to generate keys from this 313 date to the completion of the work. 314 315 If you must operate at this reduced level of security, add ' 316 options RANDOMDEV' to your kernel or modload the randomdev 317 module. You may also need to copy a new MAKEDEV to /dev and 318 recreate the random and urandom devices. 319 32020000622: 321 The license on the softupdates is now a standard 2 clause 322 BSD license. You may need to remove your symbolic links 323 that used to be required when updating. 324 32520000621: 326 Scott Flatman <sf@aracnet.com> sent in a decent write-up on 327 the config file update procedure. 328 http://people.freebsd.org/~imp/config-upd.html 329 NOTE: LINT is gone. It has been replaced with NOTES. NOTES 330 isn't buildable. However, you can generate a LINT file. 331 33220000620: 333 Binutils 2.10 have hit the tree, or will shortly. As soon 334 as they do, the problem noted in 20000522 will be resolved and 335 that workaround will no longer be required. 336 33720000615: 338 phk removed the compatibility creation of wd devices in the 339 ad driver. If you haven't done so already, you must update 340 your fstab, etc to use the ad devices instead of the wd 341 devices. 342 343 In addition, you'll need to update your boot blocks to a 344 more modern version, if you haven't already done so. Modern 345 here means 4.0 release or newer (although older releases 346 may work). 347 34820000612: 349 Peter took an axe to config(8). Be sure that you read his mail 350 on the topic before even thinking about updating. You will 351 need to create a /boot/device.hints or add a hints directive 352 to your config file to compile them in statically. The format 353 of the config file has changed as well. Please see GENERIC or 354 NEWCARD for examples of the new format. 355 35620000522: 357 A new set of binutils went into the tree today. Anybody 358 building a kernel after this point is advised that they need 359 to rebuild their binutils (or better yet do a 360 buildworld/installworld) before building a new kernel. 361 362 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf 363 or MALLOC_OPTIONS env var) J will cause ld to dump core. It 364 is recommended that you don't set this option until the problem 365 is resolved. 366 36720000513: 368 The ethernet drivers were all updated to clean up the BPF handling. 369 37020000510: 371 The problems with boot blocks on the alphas have been corrected. 372 This will require some care in updating alphas. A new libstand 373 is requires for the boot blocks to build properly. 374 37520000503: 376 Recompile all kld modules. Proper version dependency info 377 is now available. 378 37920000502: 380 Modules have been disconnected from the buildworld tree and 381 connected to the kernel building instead. 382 38320000427: 384 You may need to build gperf 385 cd /usr/src/gnu/usr.bin/gperf && make depend all install 386 when upgrading from 4.0 -> current. The build system now uses 387 an option only in -current. 388 38920000417: 390 The method that we brand ELF binaries has changed to be more 391 acceptable to the binutils maintainers. You will need to 392 rebrand your ELF binaries that aren't native. One problem 393 binary is the Linux ldconfig. After your make world, but 394 before you reboot, you'll need to issue: 395 brandelf -t Linux /compat/linux/sbin/ldconfig 396 if you have Linux compatibility enabled on your machine. 397 39820000320: 399 If you have really bad/marginal IDE drives, you may find they 400 don't work well. Use pio mode instead. The easiest way to 401 cope if you have a problem combination is to add: 402 /sbin/sysctl -w hw.atamodes=pio,pio,pio,pio 403 to the start of /etc/rc.conf. 404 40520000319: 406 The ISA and PCI compatibility shims have been connected to the 407 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old 408 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must 409 include the appropriate option in your kernel config. Drivers 410 using the shims should be updated or they won't ship with 411 5.0-RELEASE, targeted for 2001. 412 41320000318: 414 We've entered the traditional post release dumping party. 415 Large kernel changes are being committed and are in the 416 works. It is important to keep the systems' klds and kernel 417 in sync as kernel interfaces and structures are changing. 418 Before reporting kernel panics, make sure that all modules 419 that you are loading are up to date. 420 42120000315: 422 If you are upgrading from an older version of FreeBSD, you 423 need to update your boot blocks as well. 'disklabel -B ad0' 424 will do the trick. This isn't critical until you remove your 425 wd device entries in /dev, at which point your system will not 426 boot. 427 42820000315: 429 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how 430 to upgrade to 4.0 from 3.x. 431 432COMMON ITEMS: 433 434 General Notes 435 ------------- 436 Avoid using make -j when upgrading. From time to time in the 437 past there have been problems using -j with buildworld and/or 438 installworld. This is especially true when upgrading between 439 "distant" versions (eg one that cross a major release boundary 440 or several minor releases, or when several months have passed 441 on the -current branch). 442 443 To build a kernel 444 ----------------- 445 If you are updating from a prior version of FreeBSD (even one just 446 a few days old), you should follow this procedure. With a 447 /usr/obj tree with a fresh buildworld, 448 make buildkernel KERNEL=YOUR_KERNEL_HERE 449 make installkernel KERNEL=YOUR_KERNEL_HERE 450 451 To just build a kernel when you know that it won't mess you up 452 -------------------------------------------------------------- 453 cd src/sys/{i386,alpha}/conf 454 config KERNEL_NAME_HERE [1] 455 cd ../../compile/KERNEL_NAME_HERE 456 make depend 457 make 458 make install 459 460 [1] If in doubt, -r might help here. 461 462 If this fails, go to the "To build a kernel" section. 463 464 To rebuild everything and install it on the current system. 465 ----------------------------------------------------------- 466 make world 467 Build a new kernel, see above. 468 469 To upgrade from 4.x-stable to current 470 ------------------------------------- 471 make buildworld 472 make buildkernel KERNEL=YOUR_KERNEL_HERE 473 cp src/sys/${MACHINE_ARCH}/GENERIC.hints /boot/device.hints [2] 474 make installkernel KERNEL=YOUR_KERNEL_HERE 475 make installworld 476 [1] 477 <reboot> 478 479 Make sure that you've read the UPDATING file to understand the 480 tweaks to various things you need. At this point in the life 481 cycle of current, things change often and you are on your own 482 to cope. The defaults can also change, so please read ALL of 483 the UPDATING entries. 484 485 Also, if you are tracking -current, you must be subscribed to 486 freebsd-current@freebsd.org. Make sure that before you update 487 your sources that you have read and understood all the recent 488 messages there. If in doubt, please track -stable which has 489 much fewer pitfalls. 490 491 [1] If you have third party modules, such as vmware, you 492 should disable them at this point so they don't crash your 493 system on reboot. 494 495 [2] If you have legacy ISA devices, you may need to create 496 your own device.hints to reflect your unique hardware 497 configuration. 498 499FORMAT: 500 501This file contains a list, in reverse chronological order, of major 502breakages in tracking -current. Not all things will be listed here, 503and it only starts on March 15, 2000. Updating files can found in 504previous releases if your system is older than this. 505 506Please filter your entries through Warner Losh (imp@village.org) so 507that the style, formatting, etc of this file can be maintained. 508 509$FreeBSD: head/UPDATING 70621 2001-01-03 05:30:30Z imp $ 510
