1Updating Information for FreeBSD current users 2 3This file is maintained and copyrighted by M. Warner Losh 4<imp@village.org>. See end of file for further details. For commonly 5done items, please see the COMMON ITEMS: section later in the file. 6 7Items affecting the ports and packages system can be found in 8/usr/ports/UPDATING. Please read that file before running 9portupgrade. Important recent entries: 20040724 (default X changes). 10 11[[ The UPDATING file will be trimmed to 20040814 on or about Oct 1, 2004 ]] 12 13NOTE TO PEOPLE WHO THINK THAT FreeBSD 6.x IS SLOW: 14 FreeBSD 6.x has many debugging features turned on, in 15 both the kernel and userland. These features attempt to detect 16 incorrect use of system primitives, and encourage loud failure 17 through extra sanity checking and fail stop semantics. They 18 also substantially impact system performance. If you want to 19 do performance measurement, benchmarking, and optimization, 20 you'll want to turn them off. This includes various WITNESS- 21 related kernel options, INVARIANTS, malloc debugging flags 22 in userland, and various verbose features in the kernel. Many 23 developers choose to disable these features on build machines 24 to maximize performance. 25 2620040928: 27 If enabled, the default is now to run named in a chroot 28 "sandbox." For users with existing configurations in 29 /etc/namedb the migration should be simple. Upgrade your 30 world as usual, then after installworld but before 31 mergemaster do the following: 32 33 If named is running: /etc/rc.d/named stop 34 cd /etc 35 mv namedb namedb.bak 36 mkdir -p /var/named/etc/namedb 37 cp -Rp namedb.bak/* /var/named/etc/namedb/ 38 mergemaster (with your usual options) 39 If using the generated localhost* files: 40 cd /var/named/etc/namedb 41 /bin/sh make-localhost 42 rm -f localhost-v6.rev localhost.rev 43 /etc/rc.d/named start 44 45 If you are using a custom configuration, or if you have 46 customised the named_* variables in /etc/rc.conf[.local] 47 then you may have to adjust the instructions accordingly. 48 It is suggested that you carefully examine the new named 49 variables in /etc/defaults/rc.conf and the options in 50 /var/named/etc/namedb/named.conf to see if they might 51 now be more suitable. 52 5320040925: 54 BIND 9 has been imported into the base, and is now fully 55 functional. BIND 8 has now been removed. There are numerous 56 differences between BIND 8 and 9, and users with critical 57 named installations should read the migration documentation 58 in /usr/share/doc/bind9/misc/migration. There is also a 59 new instruction manual in /usr/share/doc/bind9/arm. 60 61 The key differences that most users will experience are in 62 how picky BIND 9 is about zone file format. If you are using 63 named as a resolving (caching) name server, you will likely 64 not have trouble. 65 66 The following files are part of the old BIND 8 installation 67 and should be removed: 68 /usr/bin/dnskeygen /usr/bin/dnsquery /usr/libexec/named-xfer 69 /usr/sbin/named.restart /usr/sbin/ndc 70 71 The following files have moved to /usr/bin, and should be 72 removed from their old locations: 73 /usr/sbin/nslookup /usr/sbin/nsupdate 74 7520040914: 76 The format of the pflogd(8) logfile "/var/log/pflog" has changed for 77 architectures that have a 64 bit long type to make it compatible to 78 the standard pcap format. In order to prevent corruption move away 79 any old logfile before using a new pflogd(8). 80 8120040906: 82 debug.witness_* has been renamed to debug.witness.*. There are 83 compatibility tunables left in for a few days. Update loader.conf 84 as necessary. 85 8620040902: 87 The ifi_epoch change has been reverted because the ABI breakage 88 was too extensive. If you are running with a kernel/userland 89 containing the initial change (20040830), you should heed the 90 warning about ifconfig incompatibility when upgrading again. 91 With this change, 5.3 and 6.0 ifconfigs and kernels are once 92 again interoperable. 93 9420040830: 95 A new variable, ifi_epoch, has been added to struct if_data 96 which is part if struct ifnet. This means all network drivers 97 and network monitoring applications need to be recompiled. 98 99 WARNING WARNING WARNING WARNING WARNING WARNING WARNING 100 101 This also breaks ifconfig compatibility. An old ifconfig will 102 not work with the new kernel and a new ifconfig will not work 103 with the old. It is strongly recommended that you make a copy 104 of your old ifconfig before installworld. If you are installing 105 remotely, you must copy over a new ifconfig before rebooting in 106 to the new kernel. 107 10820040828: 109 The default configuration for the network stack has been changed 110 such that it now runs without the Giant lock unless configured 111 otherwise. If you experience network-related instability, you 112 may wish to try setting "debug.mpsafenet=0" or compiling the 113 kernel with "options NET_WITH_GIANT". Details on the netperf 114 project may be found at: 115 116 http://www.watson.org/~robert/freebsd/netperf/ 117 118 Including the 20040828 announcement of configuration change 119 details. 120 12120040827: 122 PFIL_HOOKS are a fixed part of the network stack now and do not 123 need to be specified in the kernel configuration file anymore. 124 12520040819: 126 Netgraph changed its message format slightly to align the data 127 portion well on 64 bit machines. 128 Netgraph using utilities (e.g. ngctl, nghook, ppp, mpd, 129 pppoed, bluetooth, ATM) should be recompiled when a new kernel 130 is installed. 131 13220040817: 133 IPFW has been converted to use PFIL_HOOKS. This change is 134 transparent to userland and preserves the ipfw ABI. The ipfw 135 core packet inspection and filtering functions have not been 136 changed, only how ipfw is invoked is different. Note that 137 "option PFIL_HOOKS" is required to use IPFIREWALL compiled 138 into the kernel or as KLD. 139 14020040814: 141 The RANDOM_IP_ID option has been replaced by the sysctl 142 net.inet.ip.random_id. If you had RANDOM_IP_ID in your kernel then 143 you may want to add "net.inet.ip.random_id=1" to /etc/sysctl.conf. 144 14520040807: 146 The size of 'struct ifnet' has changed due to the addition of the 147 if_carp placeholder. All kernel modules implementing network 148 interfaces must be recompiled as a result. 149 15020040806: 151 Module loading has been fixed. Some older installations will 152 drop proper module_path initialization and modules will fail to 153 load properly. If you have a line in /boot/loader.rc that says: 154 "initialize drop", do (i386 only): 155 cp /usr/src/sys/boot/i386/loader/loader.rc /boot/loader.rc 156 chown root:wheel /boot/loader.rc 157 chmod 444 /boot/loader.rc 158 15920040802: 160 making /dev/(null|zero) into a module proved to be too unpopular, 161 so this bit has been revoked from the previous (20040801) entry. 162 16320040801: 164 The /dev/mem, /dev/io /dev/(null/zero) devices are now modules, 165 so you may wish to add them to your kernel config file. See 166 GENERIC for examples. 167 16820040728: 169 System compiler has been upgraded to GCC 3.4.2-pre. As with any major 170 compiler upgrade, there are several issues to be aware of. GCC 3.4.x 171 has broken C++ ABI compatibility with previous releases yet again 172 and users will have to rebuild all their C++ programs with the new 173 compiler. If you are getting run-time error such as 174 /libexec/ld-elf.so.1: Undefined symbol "_ZNSs20_S_empty_rep_storageE" 175 This entry does apply to you. 176 177 A new unit-at-a-time optimization mode, which is default in this 178 compiler release, is more aggressive in removing unused static 179 symbols. This is the likely cause of 'make buildworld' breakages 180 with non-default CFLAGS where optimization level is set to -O2 181 or higher. 182 183 With the upgrade of the system compiler, the kernel has been upgraded 184 to match the new system compiler. This makes it impossible to build 185 a new kernel with the old compiler. Upgrade your system via 186 make buildworld and make kernel (see below) to fix this problem. 187 18820040727: 189 The size of 'struct ifnet' has changed due to the addition of 190 the IFF_NEEDSGIANT flag (and what it implies). All kernel 191 modules implementing network interfaces must be recompiled as 192 a result. 193 19420040716: 195 The sound device drivers are renamed. `sound' is always required, 196 while `snd_*' should be configured accordingly to your hardware. 197 Refer to NOTES for the detail of the drivers. 198 19920040710: 200 __FreeBSD_version bumped to 502122. 201 20220040710: 203 The console initialization on Alpha has been reworked and is now 204 identical to other platforms. This means that the hardcoding of 205 the serial console and the debug port has been removed. As such, 206 hints are now required for the sio(4) driver to become a console 207 or debug port. The NO_SIO option has been decommissioned because 208 of this. 209 21020040710: 211 A revamp of the debugging code in the kernel with some visible 212 changes beyond just the debugging experience: 213 o The DDB option is now specific to the DDB debugger backend 214 and should not be used any more for conditional compilation 215 of debugging code for when debugging is enabled. Use the KDB 216 option for this. 217 o The WITNESS_DDB, DDB_TRACE and DDB_UNATTENDED options have 218 been renamed to WITNESS_KDB, KDB_TRACE and KDB_UNATTENDED 219 respectively. This is in line with the first bullet. 220 o The remote GDB support has been untangled from DDB and needs 221 to be enabled separately now. Use the GDB option for this. 222 o The GDB_REMOTE_CHAT option has been removed. Support for this 223 homegrown feature is discontinued. The GDB remote protocol 224 supports console output and it makes sense to use that. 225 o The DDB_NOKLDSYM option has been removed. The DDB debugger 226 now supports both direct symbol table lookups as well as KLD 227 symbol lookups through the linker. 228 22920040708: 230 Bluetooth code has been marked as non-i386 specific. 231 __FreeBSD_version has been bumped to 502121 to mark this change. 232 23320040702: 234 The native preemption has been added to the kernel scheduler. 235 There is some report that the ULE scheduler was broken in some 236 machines and we encourage users using the ULE scheduler either 237 stick with a known good kernel, or temporarily switch to the 4BSD 238 scheduler as a workaround. 239 24020040630: 241 The netgraph ABI version number has been incremented to indicate 242 an incompatible change in the ABI. Old netgraph nodes will refuse 243 to attach until recompiled. Netgraph now uses mbuf tags to move 244 metadata and this commit removes its home-grown metadata facility. 245 Nodes should just recompile, unless they use metadata, in which 246 case the changes are simple; the file ng_ksocket.c serves as an 247 example of such changes. 248 249 This also broke i4b, although the compile problem has been papered 250 over. 251 25220040630: 253 ACPI has been updated to disable known-bad BIOS revisions. A message 254 will be printed on the console indicating that ACPI has been disabled 255 automatically and that the user should use a newer BIOS, if possible. 256 If you think ACPI does work on your system and want to override 257 this (i.e., for testing), set hint.acpi.0.disabled="0" at the 258 loader prompt. 259 26020040623: 261 pf was updated to OpenBSD-stable 3.5 and pflogd(8) is privilege 262 separated now. It uses the newly created "_pflogd" user/group 263 combination. If you plan to use pflogd(8) make sure to run 264 mergemaster -p or install the "_pflogd" user and group manually. 265 26620040622: 267 Network interface cloning has been overhauled. This change will 268 require a recompile of modules using cloning and modification of 269 external ones to the new API. __FreeBSD_version has been bumped 270 to 502119 to mark this change. Additionally, users creating 271 stf(4) interfaces via "ifconfig stf" will need to update their 272 scripts as this will create an interface named "stf" instead of 273 "stf0" and ifconfig will not print "stf0" to stdout. 274 27520040621: 276 On 20040524, the /etc/rc.d/nsswitch script was modified to 277 automatically create /etc/nsswitch.conf on startup if it did 278 not already exist. Unfortunately, an error in the man page 279 was carried over to the script, resulting in incorrect 280 nsswitch settings. The simplest remedy is to remove both 281 /etc/nsswitch.conf and /etc/host.conf; they will be recreated 282 during the next reboot. 283 28420040614: 285 The return value of sema_timedwait(9) has been changed to 286 make it consistent with cv_timedwait(9). Be sure to recompile 287 the ips module and any third-party modules which call 288 sema_timedwait. 289 29020040613: 291 ALTQ is now linked to the build. This breaks ABI for struct ifnet. 292 Make sure to recompile modules and any userland that makes use of 293 sizeof(struct ifnet). In order to get the altq headers in place 294 please recompile and reinstall world. 295 29620040607: 297 Splitting kern_thread.c into 2 files (adding kern_kse.c) 298 requires that you re-run config after updating your tree. 299 30020040601: 301 The MIDI drivers have been removed. Until the new module-friendly 302 ones are merged, remove or comment out midi and seq from your 303 kernel configuration. 304 30520040423: 306 Due to a new option in ipfw (versrcreach) the ipfw(8) command 307 needs to be recompiled. Normal accept/reject rules without 308 options are not affected but those with options may break until 309 ipfw(8) is recompiled. 310 31120040420: 312 Due to changes in the callout ABI, kernels compiled after this 313 date may be incompatible with kernel modules compiled prior to 314 20040406. 315 31620040414: 317 The PCI bus power state stuff has been turned on. If this causes 318 problems for your system, please disable it using the tunable 319 hw.pci.do_powerstate=0. 320 32120040412: 322 The bulk of the pci problems have been fixed, although the floppy 323 drive is still broken. 324 32520040410: 326 A substantial update to the pci bus resource and power management 327 have been committed. Expect a bumpy ride for a few days until 328 the unanticipated problems have been resolved. 329 33020040409: 331 Due to changes in the the Yarrow initialization process, 332 /dev/random needs to be fed before operations requiring 333 temp files can succeed in single user mode. This includes 334 running "make installworld". /dev/random may be fed by running 335 "/etc/rc.d/initrandom start" or with 20040415 source by running 336 "/etc/rc.d/preseedrandom". 337 33820040322: 339 The debug.mpsafenet tunable controls whether the kernel Giant 340 lock is held across the lower levels of the network stack, and 341 by default is turned off. In the few days following 20040322, 342 the behavior of debug.mpsafenet will change such that this 343 tunable controls Giant over all levels of the network stack. 344 If you are currently setting debug.mpsafenet to 1, you should 345 set it back to 0 (the default) again during the change-over. 346 An additional note will be added to UPDATING when sufficient 347 locking is merged to permit this to take place. 348 34920040310: 350 The FreeBSD/sparc64 platform is changing time_t from 32-bits to 351 64-bits. This is a very major incompatible change, so people 352 using FreeBSD/sparc64 *must* read the UPDATING.64BTT file for 353 detailed instructions on how to make this upgrade. People 354 upgrading FreeBSD on other platforms can ignore this event. 355 35620040308: 357 The packet filter (pf) is now installed with the base system. Make 358 sure to run mergemaster -p before installworld to create required 359 user account ("proxy"). If you do not want to build pf with your 360 system you can use the NO_PF knob in make.conf. 361 Also note that pf requires "options PFIL_HOOKS" in the kernel. The 362 pf system consists of the following three devices: 363 device pf # required 364 device pflog # optional 365 device pfsync # optional 366 36720040303: 368 If you are having trouble with the libc_r -> libpthread transition 369 (see the 20040130 entry), place the following lines at the top of 370 /etc/libmap.conf: 371 372 libc_r.so.5 libpthread.so.1 373 libc_r.so libpthread.so 374 375 This will cause all programs and libraries linked against libc_r 376 to use libpthread instead. 377 37820040226: 379 Some sshd configuration defaults have changed: protocol version 1 380 is no longer enabled by default, and password authentication is 381 disabled by default if PAM is enabled (which it is by default). 382 OpenSSH clients should not be affected by this; other clients may 383 have to be reconfigured, upgraded or replaced. 384 38520040225: 386 The ABIs defined in <resolv.h> and <netdb.h> have been updated 387 to support improved reentrancy. Multi-threaded programs that 388 reference the "_res" or "h_errno" symbols may experience some 389 problems if they are not recompiled. Single-threaded programs 390 should remain unaffected. 391 39220040225: 393 routed has been updated in the base system from the vendor 394 sources, routed v2.27, from rhyolite.com. This change means that 395 for users who use RIP's MD5 authentication feature, FreeBSD 396 -CURRENT's routed is now incompatible with previous versions 397 of FreeBSD; however it is now compatible with implementations 398 from Sun, Cisco and other vendors. 399 40020040224: 401 The tcpcb structure has changed and makes a recompile of libkvm 402 and related userland network utilities necessary. 403 40420040222: 405 The cdevsw structure has changed in two externally visible ways. 406 First, the sense of the D_GIANT flag has changed to D_NEEDSGIANT. 407 Second, the d_version field must be filled in with D_VERSION. 408 Drivers outside the tree will need to be updated. 409 41020040207: 411 The /etc/rc.d/ttys script has been removed. It is no longer 412 necessary since devfs has been mandatory for some time. 413 41420040130: 415 libkse has been renamed back to libpthread and is now the 416 default threads library. The gcc -pthread option has also 417 been changed to link to libpthread instead of libc_r. For 418 alpha and sparc64 machines, libkse is not renamed and links 419 are installed so that libpthread points to libc_r. Until 420 the ports system is updated to handle this change, it is 421 recommended that folks install an /etc/libmap.conf(5) that 422 maps libc_r to libpthread. If you have any binaries or 423 libraries linked to libkse, then it is also recommended 424 that you map libkse to libpthread. Anyone that is using 425 nvidia supplied drivers and libraries should use a libmap.conf 426 that maps libpthread to libc_r since their drivers/libraries 427 do not work with libpthread. 428 42920040125: 430 ULE has entered into its probationary period as the default scheduler 431 in GENERIC. For the average user, interactivity is reported to be 432 better in many cases. On SMP machines ULE will be able to make more 433 efficient use of the available parallel resources. If you are not 434 running it now, please switch over, replacing the kernel option 435 SCHED_4BSD with SCHED_ULE. 436 43720040125: 438 Move LongRun support out of identcpu.c, where it hardly 439 belongs, into its own file and make it opt-in, not mandatory, 440 depending on CPU_ENABLE_LONGRUN config(8) option. 441 44220031213: 443 src/lib/libc/gen/initgroups.c:1.8 now causes logins to fail 444 if the login process is unable to successfully set the 445 process credentials to include all groups defined for the 446 user. The current kernel limit is 16 groups; administrators 447 may wish to check that users do not have over 16 groups 448 defined, or they will be unable to log in. 449 45020031203: 451 The ACPI module has been reactivated. It is no longer required 452 to compile ACPI support into kernels statically. 453 45420031112: 455 The statfs structure has been updated with 64-bit fields to 456 allow accurate reporting of multi-terabyte filesystem 457 sizes. You should build world, then build and boot the new kernel 458 BEFORE doing a `installworld' as the new kernel will know about 459 binaries using the old statfs structure, but an old kernel will 460 not know about the new system calls that support the new statfs 461 structure. 462 Note that the backwards compatibility is only present when the 463 kernel is configured with the COMPAT_FREEBSD4 option. Since 464 even /bin/sh will not run with a new kernel without said option 465 you're pretty much dead in the water without it. Make sure you 466 have COMPAT_FREEBSD4! 467 Running an old kernel after a `make world' will cause programs 468 such as `df' that do a statfs system call to fail with a bad 469 system call. Marco Wertejuk <wertejuk@mwcis.com> also reports 470 that cfsd (ports/security/cfs) needs to be recompiled after 471 these changes are installed. 472 473 ****************************DANGER******************************* 474 475 DO NOT make installworld after the buildworld w/o building and 476 installing a new kernel FIRST. You will be unable to build a 477 new kernel otherwise on a system with new binaries and an old 478 kernel. 479 48020031112: 481 Some netgraph string length constants have been changed. This 482 change requires the netgraph kernel modules and all netgraph 483 userland components to be in sync. Especially users who require 484 netgraph to boot need to make sure to have world and kernel in 485 sync before rebooting. 486 48720031111: 488 Hyperthreading logical CPU's are no longer probed by default 489 when using the MP Table. If ACPI is being used, then logical 490 CPUs will be probed if hyperthreading is enabled in the BIOS. 491 If ACPI is not being used and hyperthreading is enabled in the 492 BIOS, logical CPUs can be enabled by building a custom kernel 493 with the option MPTABLE_FORCE_HTT enabled. 494 49520031103: 496 The i386 APIC_IO kernel option has been replaced by 497 'device apic'. The ACPI module has also been temporarily 498 disabled, so ACPI must be statically compiled into your 499 kernel using 'device acpi' if you wish to use the ACPI driver. 500 50120031031: 502 The API and ABI of struct ifnet have been changed by removing 503 the if_name and if_unit members and replacing them with 504 if_xname, if_dname, and if_dunit. All network drivers and most 505 userland programs which include net/if_var.h must be updated 506 and recompiled. __FreeBSD_version has been bumped to 501113 to 507 reflect this change. 508 50920030928: 510 Changes to the cdevsw default functions have been made to remove 511 the need to specify nullopen() and nullclose() explicitly. 512 __FreeBSD_version bumped to 501110. 513 51420030926: 515 kiconv(3) has been added. mount_msdosfs(8), mount_ntfs(8) and 516 mount_cd9660(8) need to be in sync with kernel. 517 51820030925: 519 Configuring a system to use IPFILTER now requires that PFIL_HOOKS 520 also be explicitly configured. Previously this dependency was 521 magically handled through some cruft in net/pfil.h; but that has 522 been removed. Building a kernel with IPFILTER but not PFIL_HOOKS 523 will fail with obtuse errors in ip_fil.c. 524 52520030923: 526 Fix a bug in arplookup(), whereby a hostile party on a locally 527 attached network could exhaust kernel memory, and cause a system 528 panic, by sending a flood of spoofed ARP requests. See 529 FreeBSD-SA-03:14.arp. 530 53120030915: 532 A change to /etc/defaults/rc.conf now causes inetd to be started 533 with `-C 60' if it is not overridden in /etc/rc.conf. This 534 causes inetd to stop accepting connections from an IP address 535 that exceeds the rate of 60 connections per minute. 536 53720030829: 538 The following rc.d scripts have been removed and should be 539 deleted from your installation: atm2.sh atm3.sh devdb 540 localdaemons network1 network2 network3. Depending on when 541 you last updated world and used mergemaster(8) you may or 542 may not have problems during the rc boot sequence. The simplest 543 solution is an 'rm -rf /etc/rc.d/*' and then 'mergemaster -i'. 544 The atm2.sh atm3.sh and devdb scripts were removed some time 545 ago, so depending on when you installed -CURRENT these scripts 546 may or may not exist on your system. 547 54820030824: 549 ATAng has been committed. You need to build world as sys/ata.h 550 has changed, and userland atacontrol depends on it. 551 If you use ATA SW raids you need "device ataraid" in your 552 kernel config file, as it is no longer pulled in automatically. 553 55420030819: 555 The OFW_NEWPCI option has been turned on in the Sparc64 GENERIC kernel. 556 Among other things, this changes the device enumeration to be 557 closer to Solaris. Be aware that, this can even cause the machine 558 to not boot without manual intervention before the fstab is adjusted. 559 56020030728: 561 All current USB and Firewire quirks in da(4) have been deprecated 562 and will be removed for 5.2. If this causes failure for your 563 umass(4) devices, enable "options DA_OLD_QUIRKS" in your kernel 564 and send the output of "camcontrol inquiry da0" to scsi@freebsd.org 565 so the quirk can be re-enabled. 566 56720030724: 568 Problems with entry 20030714 have been corrected and no known issues 569 with /rescue and -j exist for host systems after this point in time. 570 57120030722: 572 FPU-less support has been removed from FreeBSD. Chances are you won't 573 notice. 386+387 support should still work after this change, but 574 it is now a minimum requirement for the i386 port that you have real 575 FPU hardware. 576 57720030714: 578 Some people are having problems with changes related to /rescue. 579 If you are building -j N, you will need to define NO_RESCUE. Others 580 will need to define it if /rescue has issues with their environment. 581 People should report those issues to current@. 582 58320030711: 584 gcc was upgraded to 3.3. You are advised to not build -DNOCLEAN 585 across this point. Further, it might be a good idea to remove 586 /usr/obj. 587 58820030610: 589 Remove deprecated locale names and transition period code 590 for them, finishing switching to the new scheme. Check your 591 LANG environment variable. 592 59320030609: 594 CCD has been changed to be a fully GEOMified class. Kernel 595 and ccdconfig(8) needs to be in sync, this is particularly 596 important to remember beforehand if your source tree is on 597 a ccd device. Consider making a copy of the old ccdconfig 598 into /boot/kernel.good or wherever you keep your backup 599 kernel. 600 60120030605: 602 There was a small window in which sed(1) was broken. If you 603 happen to have sed(1) installed during that window, which is 604 evidenced by an inability to build world with the failure 605 given below, you need to manually build and install sed(1) 606 (and only sed(1)) before doing anything else. This is a one- 607 time snafu. Typical failure mode: 608 609 In file included from /usr/src/contrib/binutils/bfd/targets.c:1092: 610 targmatch.h:7:1: null character(s) ignored 611 targmatch.h:12:1: null character(s) ignored 612 targmatch.h:16:1: null character(s) ignored 613 : 614 615 The window of "sed(1)-uction" is from Wed Jun 4 15:31:55 2003 UTC 616 to Thu Jun 5 12:10:19 2003 UTC (from rev 1.30 to rev 1.31 of 617 usr.bin/sed/process.c). 618 61920030505: 620 Kerberos 5 (Heimdal) is now built by default. Setting 621 MAKE_KERBEROS5 no longer has any effect. If you do NOT 622 want the "base" Kerberos 5, you need to set NO_KERBEROS. 623 62420030502: 625 groff has been updated. If you try to do a buildworld and 626 get an infinite loop in troff, update to May 4th or newer. If you 627 have a newer kernel than userland, you may need to set the OSRELDATE 628 to 500110 in your environment before starting a buildworld. 629 63020030501: 631 The old rc system has been removed. Please report any problems 632 to freebsd-rc@yahoogroups.com, and/or freebsd-current@freebsd.org. 633 Your personal versions of these files will not be removed, so you can 634 continue to use them. However, you should take great care when updating, 635 especially when using mergemaster, since the compatibility code that 636 utilizes these old scripts has also been removed. 637 63820030423: 639 A bug has been fixed in /dev/devctl which would cause devd 640 to hang on boot, were it not for a workaround in devd. The 641 work around in devd will be removed around 20030507. You 642 have until then to upgrade your kernel before updating 643 userland. In general, you should have a userland and 644 kernel that's in sync with each other. However, given the 645 effects of this bug (hang on boot when starting devd), some 646 allowances are made. 647 64820030329: 649 Alphas with libc from between 20030312 and 20030329 exhibit 650 floating point exceptions (FPEs), most notably in awk(1) 651 while upgrading the system through a buildworld. 652 653 So, to successfully upgrade your Alpha, you must either 654 downgrade your libc.so to a pre-20030312 version, or update 655 /usr/share/mk/bsd.cpu.mk to revision 1.26 which adds -mieee 656 to CFLAGS, then forcibly rebuild and install libc: 657 658 cd /usr/src/lib/libc && \ 659 make cleandir && make obj && \ 660 make -DNOMAN -DNOPROFILE all && \ 661 make -DNOMAN -DNOPROFILE install 662 66320030208: 664 sendmail 8.12.7 has been imported. It has one important 665 change for IPv6 users. The default submit.mc now uses 666 '[127.0.0.1]' instead of 'localhost' meaning only IPv4 is 667 used to connect to the MTA. Users on IPv6-only machines 668 will need to edit /etc/mail/submit.mc appropriately. 669 67020030128: 671 NODEVFS option has been removed and DEVFS thereby made standard. 672 This makes all references to MAKEDEV obsolete, and they should 673 be removed when convenient. 674 67520030126: 676 The name of the device for the ofw console has changed, sparc64 users 677 must run mergemaster to update their installed /etc/ttys. 678 67920030125: 680 The scheduler framework has grown a second scheduler and consequently 681 you must specify one and only one scheduler in your kernel config. 682 The cvs config files have been updated to use the old scheduler 683 which may be selected via 'options SCHED_4BSD'. If you would like 684 to try the new, much more experimental, scheduler please try 685 'options SCHED_ULE' and contribute to the arch@ discussion. 686 68720030115: 688 A new version of the wi driver has been imported into the tree. 689 One now must have device wlan in the config file for it to operate 690 properly. 691 692 In addition, there have been some changes to how wi devices are 693 configured for point to point links to bring it more in line 694 with the former way of doing things, as well as compatibility 695 with NetBSD. 696 69720021222: 698 For a period after the GCC 3.2.1 import (from 12/04 to 12/22), GCC 699 used an incompatible form of ABI for returning structures and unions 700 which FreeBSD's GCC maintainers were not aware of relative to previous 701 versions of FreeBSD. We have gone back to the ABI for now, and any 702 code compiled which is required to interoperate with other code (not 703 built at the same time) returning structs or unions should be 704 rebuilt. 705 70620021216: 707 A name change in /etc/netconfig has been reverted to stay 708 compatible with suns TIRPC and also with NetBSD. You need 709 to run mergemaster after make world. A new libc does still work 710 with an outdated /etc/netconfig for some time, but you'll get 711 a warning. This warning will be removed in 20030301. 712 71320021202: 714 The recent binutils upgrade marks a kernel flag day on 715 sparc64: modules built with the old binutils will not work 716 with new kernels and vice versa. Mismatches will result in 717 panics. Make sure your kernel and modules are in sync. 718 71920021029: 720 The value of IPPROTO_DIVERT has changed. Make sure to keep 721 your kernel, netstat, natd and any third-party DIVERT 722 consumers in sync. 723 72420021024: 725 Old, compatibility slices have been removed in GEOM kernels. 726 This means that you will have to update your /etc/fstab to 727 not use disk devices of the form /dev/ad0a. Instead, you 728 now must specify /dev/ad0s1a, or whatever slice your FreeBSD 729 partition really is on. The old device names have gone 730 away, so if you use them anywhere else, you must also adjust 731 those uses. (This doesn't affect the disks formatted in 732 the ``dangerously-dedicated'' mode.) 733 73420021023: 735 Alphas with kernels from between 20020830 and 20021023 and/or 736 rtld (ld-elf.so.1) older than 20021023 may experience problems 737 with groff while doing a buildworld (kernel: "out of memory", 738 fixed in rev 1.129 of kern/imgact_elf.c; rtld: "too few PT_LOAD 739 segments", fixed in rev 1.8 of libexec/rtld-elf/map_object.c). 740 741 So, to successfully upgrade your Alpha, you must either 742 upgrade your kernel and rtld first (which might be a bit 743 tricky), or avoid running the bootstrapped groff during the 744 "transitional" buildworld. To avoid running groff during the 745 transitional upgrade run make buildworld with -DNOMAN, 746 -DNO_SHAREDOCS, and -DNO_LPR. 747 74820020831: 749 gcc has been upgraded to 3.2. It is not all binary compatible 750 with earlier versions of gcc for c++ programs. All c++ 751 programs and libraries need to be recompiled. 752 753 Also, if you encounter g++ issues, rm /usr/include/g++/* before 754 doing an installworld to make sure that stale files are removed. 755 75620020827: 757 Our /etc/termcap now has all the entries from the XFree86 xterm 758 almost unchanged. This means xterm now supports color by default. 759 If you used TERM=xterm-color in the past you now should use 760 TERM=xterm. (xterm-color will lead to benign warnings). 761 76220020815: 763 A "bug" in gcc(1) that was hiding warning in system headers was 764 fixed. It's probably time to add -DNO_WERROR to your make line 765 again. 766 76720020729: 768 COPY is being deprecated. The 20010530 change was reverted, as 769 it causes far more pain than was expected, and to always compare 770 before installing, please use INSTALL="install -C" again. The 771 -C option is now silently ignored when used with the -d option. 772 77320020702: 774 Problems with libc_r clients like KDE and GNOME have been resolved. 775 There are still some minor problems with some signals but the 776 system is stable enough for general use again. SMP is less so than UP 777 but each can successfully complete multiple buildworlds. 778 Libkvm needs to be recompiled due to KSE. 779 78020020701: 781 Now would be a bad time to upgrade. Something in or near the 782 KSE commit totally broke programs using libc_r like KDE and 783 GNOME. 784 78520020511: 786 The k5su utility installed as part of Kerberos 5 is no longer 787 installed with the set-user-ID bit set by default. Add 788 ENABLE_SUID_K5SU=yes to /etc/make.conf to have it installed 789 with the set-user-ID bit set. 790 79120020510: 792 Gcc 3.1 debugging format (cc -g) has changed from STABS to DWARF2. 793 Unfortunately our native GDB (at version 4.18) does not understand 794 the DWARF2 debugging format. Thus you must use `gcc -gstabs+' to 795 generated debugging information for our native GDB. 796 79720020510: 798 Due to the way CVS works, it may not properly update src/contrib/gcc 799 to the 3.1 sources. The easiest fix is to `rm -rf' src/contrib/gcc 800 and then do a cvs update. 801 80220020421: 803 When exec'ing set[ug]id executables, the kernel now ensures that the 804 stdio file descriptors (0..2) are open. See FreeBSD-SA-02:23.stdio. 805 80620020404: 807 New sendmail startup scripts have been installed to make it 808 easier to use alternative MTAs with FreeBSD. Setting the rc.conf 809 variable sendmail_enable to "NO" no longer prevents any sendmail 810 daemons from starting. Instead, either set sendmail_enable to 811 "NONE" or change mta_start_script to a script for starting 812 an alternative MTA. Setting mta_start_script to "" will 813 also prevent any MTA from being started at boot. 814 81520020403: 816 UCONSOLE is no longer a valid kernel option. 817 81820020315: 819 FreeBSD 5.0 DP-1 was basically branched today. 820 82120020225: 822 Warnings are now errors in the kernel. Unless you are a developer, 823 you should add -DNO_WERROR to your make line. 824 82520020217: 826 sendmail 8.12.2 has been imported. The sendmail binary is no 827 longer a set-user-ID root binary and the infrastructure to support 828 command line mail submission has changed. Be sure to run 829 mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf, 830 and /etc/mail) and read /etc/mail/README for more details. 831 832 Due to the import of sendmail 8.12.2, a new user and group are 833 required in order for sendmail to run as a set-group-ID 834 binary. A 'make installworld' will use the new user and group 835 to set the owner and group of /var/spool/clientmqueue and will 836 fail if the new user and group do not exist. The 'smmsp' user 837 and group must be merged from src/etc/group and 838 src/etc/master.passwd before using 'make installworld'. 839 'mergemaster -p' will do this. You may need to install 840 mergemaster before this will work if you are updating from a 841 very old version of current. The updating recipe has changed 842 as of this date. 843 84420020112: 845 The preferred configuration method for PAM is now /etc/pam.d/ 846 rather than /etc/pam.conf. If you have an unmodified 847 pam.conf, just delete it after your next mergemaster run. If 848 you have local modifications, you can use 849 /usr/src/etc/pam.d/convert.pl to incorporate them into your 850 /etc/pam.d. 851 852 Please see the following url for more details: 853http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<xzp6667fyoa.fsf@flood.ping.uio.no> 85420011229: 855 If anyone here is already using the new rc.conf(5) variable 856 networkfs_types, please note that it has changed 857http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<9744.1009655556@axl.seasidesoftware.co.za> 858 85920011220: 860 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file 861 started out its life in the ISDN4BSD project as an offspring 862 from sys/net/if_spppsubr.c, which eventually got a life of its 863 own. All the accumulated features and bug fixes of the i4b 864 version have now been merged back into the base system's 865 version now. The only user-visible change resulting from this 866 is that i4b's sppp(4) interfaces are to be managed with 867 spppcontrol(8) again, since ispppcontrol(8) has been retired 868 as well. (There has never been rc file support for 869 ispppcontrol in -current, but only in -stable. That will be 870 reverted by the time the changes are MFCed.) 871 87220011215: 873 The fdc(4) driver has been updated and now automatically 874 recognizes media in `standard' formats (like 1440 KB and 875 720 KB for a 3.5" high-density drive) when accessing the 876 default device node (e. g. /dev/fd0). The old variety of 877 floppy device nodes /dev/fd*.* is no longer present by 878 default, devices can be created (in DEVFS) on demand. They 879 will need to be customized then for `odd' densities using 880 fdcontrol(8). 881 88220011209: 883 The bugs in procfs' debugging support code have been fixed, 884 and truss(1) now works again. 885 88620011207: 887 Daily security checks have been split out to use the periodic(8) 888 scripts. Some change in configuration may be necessary. Please 889 see 890http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org> 891 for details. 892 89320011204: 894 sos added VCD/SVCD support to ata driver and that needs the 895 kernel and burncd to be in sync. 896 89720011203: 898 The procfs pseudo-filesystem has now been converted to use the 899 pseudofs framework. If you have 'options PROCFS' in your 900 kernel config, you'll need to add 'options PSEUDOFS' if it's 901 not there already. 902 903 This change temporarily breaks truss(1); use ktrace(1) instead 904 until the issue has been resolved. 905 90620011202: 907 A security hole in OpenSSH involving `UseLogin yes' has been 908 patched. 909 91020011126: 911 You need to remove /usr/obj/.../usr.bin/tip before rebuilding 912 after this date. You need to do this only once. 913 91420011103: 915 Most of the awk issues have been resolved. Some rough 916 edges may be left, but for the most part things should be 917 back to "normal." For CURRENT's usual definition of "normal." 918 91920011030: 920 Awk has been upgraded to the one true awk from bell labs. Expect 921 choppy waves in the upgrade process. 922 92320011030: 924 The asr driver problem has been resolved. 925 92620011027: 927 Due to changes in other parts of the system, the asr driver 928 now causes the system to panic on boot. Do not use it pending 929 correction. Comment it out of any kernel config file that you 930 try to use from this date forward. 931 93220011025: 933 When crossbuilding, use TARGET=xxx where you used to use 934 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET, 935 unless you are changing both of them. To cross build pc98 on 936 an alpha, for example, you need to set TARGET=pc98 and 937 TARGET_ARCH=i386. 938 93920011001: 940 The kernel interface that burncd depends on has changed. 941 You must recompile both the kernel and userland applications 942 at the same time. 943 94420010929: 945 When crossbuilding, please set TARGET_ARCH rather than 946 MACHINE_ARCH to indicate the target. In the future, one will 947 set TARGET_MACHINE where you set MACHINE now. At the moment, 948 setting MACHINE alone for same MACHINE_ARCH machines works 949 (eg, you can build pc98 on an i386 machine and vice versa). 950 95120010927: 952 Some weird problems result from using ACPI on some machines. 953 To disable ACPI you can add 954 hint.acpi.0.disabled="1" 955 to /boot/loader.conf (or by putting set X=Y at the boot 956 loader "ok" prompt). 957 958 Alternatively, you can remove it from /boot/kernel/acpi.ko 959 or use the MODULES_OVERRIDE function in your kernel config 960 file and not list acpi in that list. 961 96220010924: 963 The buildworld has been fixed. You may need to install 964 the 4.x compatibility libraries for some old binaries 965 to work. Add COMPAT4X=true to your /etc/make.conf to 966 get them installed on every installworld, or execute the 967 following to get them installed only once: 968 cd src/lib/compat/compat4x.<arch> 969 make all install 970 You will see ``__stdoutp undefined'' until you do this. 971 97220010919: 973 There's a bug in the world build process. The cross-tools 974 are build with the NEW headers, but the OLD libc.a. This 975 leads to all kinds of problems with the new libc. A temporary 976 workaround is to add 977 CFLAGS="-O -pipe -D_OLD_STDIO" 978 before building world when upgrading from 4.x to current. This 979 can be removed afterwards. 980 981 A proper fix to the buildworld target is needed. 982 98320010918: 984 Peter has committed his new kthread nfs client/server code. 985 NFS may be unstable after this date. 986 98720010912: 988 KSE has hit the tree. Lots of things are now different in 989 the kernel. While a few problems were introduced in the 990 initial commit, most of the major ones have been found and 991 corrected. 992 99320010901: 994 In OLDCARD, CardBus bridges appear to be stable. The work 995 arounds described in the 20010604 entry are now no longer 996 necessary and will be ignored. Most insert/remove problems 997 have been rectified around this date. 998 99920010823: 1000 named now runs as user bind and group bind rather than as 1001 root. If named_enable is set to YES in /etc/rc.conf, ensure 1002 that user bind is available in /etc/passwd (using vipw(8)) 1003 and that group bind is available in /etc/group. Also make 1004 sure that user or group bind has read (and not write) 1005 permission for your name server configuration and that it 1006 has read and write permission for your slave zone files and 1007 directory. 1008 1009 If you wish to continue to run named as root (a less secure 1010 alternative), add a line to /etc/rc.conf saying 1011 1012 named_flags= 1013 101420010709: 1015 The PAM libraries have had an API upgrade that is beyond 1016 the ability of the shared library major number to handle. 1017 It is manifested by PAM-using ports dumping core. The 1018 solution is to rebuild those ports. 1019 102020010628: 1021 The kernel compile module has moved from src/sys/compile/FOO 1022 to src/sys/${MACHINE}/compile/FOO. 1023 102420010625: 1025 The pccard modem issue from 20010613 has been corrected. 1026 OLDCARD support is still a little weak in -current. slot 1 is 1027 known not to work on some TI based cardbus bridges. Some 1028 cardbus bridges do not properly detect insert/removal events. 1029 IRQ configuration needs more safety belts. 1030 103120010617: 1032 Softupdates problems have been corrected. 1033 103420010614: 1035 Peter ripped out the linkerset support. You must, as always, 1036 rerun config after you cvsup if you are using the traditional 1037 kernel building methods. 1038 103920010613: 1040 pccard modems may not work with current after 20010604 date. Some 1041 do, others result in panics. *MAKE*SURE* that you update your 1042 config and /etc/rc.conf ala the 20010604 entry, or you will have 1043 problems (this issue will be fixed, it just hasn't been yet). 1044 104520010613: 1046 SOFTUPDATES seem to be broken since the middle of May or so. Do not 1047 use them in current. You can disable softupdates on all mounted 1048 partitions, or remove SOFTUPDATES the kernel config file. 1049 105020010612: 1051 After Peter's commits to the hints code, people have been noticing 1052 that certain devices are attached (or try to) twice. This is due 1053 to having both static hints as well as a /boot/device.hints. To 1054 work around this issue, please use only one or the other mechanism 1055 until this bug is fixed. 1056 1057 Please note that a feature of config is that if you have config 1058 file FOO and FOO.hints, it automatically adds FOO.hints to the 1059 hints.c file, whether you want it to or not. 1060 106120010610: 1062 Locale names have changed to match other systems better. 1063 106420010604: 1065 pccard support for pci cards has been committed. You must change 1066 your /etc/pccard.conf irq lines. It must match the irq used by 1067 pcic device. Interrupt storms may result if you fail to do this. 1068 Interrupt storms look a lot like a hang. 1069 1070 You must also install a new pccardd, otherwise you will get an 1071 interrupt storm at card reset time (just after it tells you what 1072 it is). 1073 1074 pccardd_flags="-I" is necessary for the time being. It tells pccardd 1075 not to ask the kernel if the interrupt is really free or not before 1076 using it. You can either change the /etc/pccard.conf irq lines to 1077 match pcic, or add "-i X" to the pccardd_flags. 1078 107920010530: 1080 INSTALL=install -C is being deprecated. If you want to do this, 1081 use COPY=-C instead. The former method will be supported for only 1082 a limited time. If you see 1083 1084install: warning: the -d and -C options may not be specified together 1085 1086 in your makeworld, then you need to migrate towards using 1087 COPY=-C. 1088 108920010525: 1090 It appears that vm is now stable enough to use again. However, 1091 there may be other problems, so caution is still urged. alpha 1092 definitely is in bad shape. 1093 109420010521: 1095 Minor repo damage has happened. This may cause problems 1096 with cvsup of ports. If you get errors, please see 1097 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495 1098 at the bottom for details on a workaround. The error message 1099 is 1100Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty 1101 110220010520: 1103 Vm and/or swapping are busted on -current. Please be patient. 1104 110520010519: 1106 pccard has had much reorganizational work done to it over 1107 the past few days. Everything should still work, but if 1108 not, please contact imp@freebsd.org. 1109 111020010517: 1111 ata ioctl changed. Make sure to recompile both kernel and 1112 userland at the same time. 1113 111420010517: 1115 New ncurses imported. 1116 111720010512: 1118 DEVFS is now opt out, not opt in. Barring major problems, this 1119 will be the only way to go starting July 1. 1120 112120010504: 1122 OpenSSH has been updated to 2.9. Some defaults are different, 1123 including RhostsRSAAuthentication, which changes from yes to no. 1124 112520010502: 1126 Perl breakage in 20010501 was corrected at 14:18:33 PDT. 1127 112820010501: 1129 Building perl was broken at 02:25:25 PDT. 1130 113120010430: 1132 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to 1133 go back in the water. 1134 113520010429: 1136 A bad bug was committed at 04:48:42 PDT. Don't use kernels after 1137 this date, but before the correction date. 1138 113920010423: 1140 old fsck and new kernel interactions appear to have been fixed. 1141 114220010411: 1143 fsck and the kernel were changed to handle some optimizations 1144 to directory layout. This breaks backward compatibility. 1145 Update only if you understand that you must not use the old 1146 fsck with the new kernel ever. 1147 114820010330: 1149 fsck has changed the meaning of the pass column in /etc/fstab. 1150 Please see the cvs commit to fsck.8 or the fsck.8 man page for 1151 details. It is unclear if changes to /etc/fstab are necessary. 1152 115320010319: 1154 portmap had changed name to rpcbind for maximum POLA in your 1155 current world. /etc/hosts.{allow,deny} needs changes. nfs and 1156 other rpc based programs that rely on portmapper will not work 1157 without updates to /etc/hosts.{allow,deny} and /etc/netconfig. 1158 115920010315: 1160 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC 1161 and ATA_ENABLE_TAGS are no longer kernel options. They have 1162 been replaced by tunables. See ata.4 for details. 1163 116420010312: 1165 The fxp driver was converted to use miibus. If you compile 1166 fxp into your kernel statically, you will need to add miibus. 1167 116820010312: 1169 The wi device now defaults to BSS (infrastructure) mode 1170 instead of ad-hoc. 1171 117220010310: 1173 /dev/urandom should be a symbolic link to /dev/random now. 1174 Users of current not using DEVFS need to run MAKEDEV std. 1175 ssh might not work if you don't. 1176 117720010303: 1178 The ed driver has been updated. It now allows mii attachments, 1179 which means that you must include the miibus in your kernel if 1180 you use the ed driver. 1181 118220010220: 1183 The problems with libc have been corrected. It is now mostly 1184 safe to go back into the water. 1185 118620010211: 1187 The size of FILE was changed. This breaks upgrading. If 1188 you must upgrade, be prepared for pain. It also breaks almost 1189 all binaries that you've compiled on -current. You are warned 1190 that before upgrading would be a good time to do a level 0 1191 dump of your system. No, really, I mean it this time. 1192 1193 To get to the new system, you'll need to use the following 1194 workaround. Hopefully this can be sorted out so that we 1195 don't have to move this to the updating section. 1196 1197 To get around the installworld problem, do: 1198 # cd /usr/src/usr.bin/sed 1199 # make install 1200 # cd /usr/src 1201 # make installworld 1202 If that doesn't work, then try: 1203 # make -k installworld 1204 # make installworld 1205 120620010207: 1207 DEVFS is now the default. If you use vinum, make sure that you 1208 do not include devfs in your kernel as problems result. 1209 121020010205: 1211 FFS_ROOT and CD9660_ROOT have been removed or deprecated. 1212 Remove them from your config. 1213 121420010122: 1215 ****************************** WARNING ****************************** 1216 buildkernel has been changed slightly 1217 ****************************** WARNING ****************************** 1218 KERNCONF replaces the variable KERNEL for buildkernel. You 1219 should update your scripts and make.conf accordingly. 1220 122120010119: 1222 config has changed to allow DEV_FOO as a replacement for NFOO. 1223 This requires a new config to build correctly. 1224 122520010116: 1226 The kernel option I386_CPU is now mutually exclusive with the 1227 other cpu types. If you have an i386 system, be sure that it 1228 only had this line. Remove it for all other configurations. 1229 123020010110: 1231 Changes to the kernel require it and burncd be in sync. 1232 123320010102: 1234 Everyone who has hw.sndunit set to something in 1235 /etc/sysctl.conf, it is now hw.snd.unit. 1236 123720010101: 1238 ex and vi were broken by some changes to sys/queue.h. If you 1239 have a bad vi, you will see make buildworld fail with a core 1240 dump while building termcap. You can work around this problem 1241 by adding -k to your make buildworld. This will cause the 1242 build to complete and install a new vi. Once that's done, you 1243 can rebuild again without the -k to pick up anything that 1244 might have been ignored by the -k option. 1245 1246 Others have suggested that you can just rebuild libc if your 1247 vi/ex is dynamically linked, but I've not received any reports 1248 of this working. 1249 125020001228: 1251 There have been some changes to libcrypt in -current. The 1252 libscrypt/libdescrypt symlink silliness is gone and the installed 1253 libcrypt is fully functional. Be aware of this. 1254 125520001218: 1256 Linksys Fast Ethernet PCCARD cards supported by the ed driver 1257 now require the addition of flag 0x80000 to their config line 1258 in pccard.conf(5). This flag is not optional. These Linksys 1259 cards will not be recognized without it. 1260 126120001205: 1262 Important new FreeBSD-version stuff: PAM support has been worked 1263 in, partially from the "Unix" OpenSSH version. This requires 1264 adding the following in pam.conf: 1265 1266 sshd auth sufficient pam_skey.so 1267 sshd auth required pam_unix.so try_first_pass 1268 sshd session required pam_permit.so 1269 127020001031: 1271 cvs updated to 1.11. 1272 127320001020: 1274 The random device needs more entropy, so you need to make sure 1275 that you've run mergemaster to get a /etc/rc which will seed 1276 /dev/random. If you don't and the system hangs after ldconfig, 1277 then banging on the keyboard randomly until it unhangs is one 1278 workaround. 1279 128020001010: 1281 ****************************** WARNING ****************************** 1282 Sendmail has been updated. 1283 ****************************** WARNING ****************************** 1284 o mail.local(8) is no longer installed as a set-user-id binary. 1285 o sendmail(8) is now built with STARTTLS support unless NO_OPENSSL 1286 is set. 1287 o The default /etc/mail/sendmail.cf disables the SMTP EXPN and VRFY 1288 commands. 1289 o Now using sendmail's version of vacation(1). 1290 o The sendmail cf building tools (contrib/sendmail/cf) are installed 1291 in /usr/share/sendmail/cf. 1292 o sendmail.cw changed to local-host-names 1293 1294 More details can be found at 1295 http://people.freebsd.org/~imp/UPDATING/sendmail-20001010 1296 129720001009: 1298 The ports tree's new layout is in place. Be sure to update 1299 your entire ports tree, or you will have problems. 1300 130120001006: 1302 The perl build procedure no longer installs miniperl, nor uses 1303 the installed miniperl. It is recommended that you delete 1304 /usr/bin/miniperl. 1305 130620001005: 1307 This weekend the ports tree will be updated to a new layout. 1308 It will be in an inconsistent state until noted in the UPDATING 1309 file, or with asami-san's message to the relevant mailing 1310 lists. With this new layout, you'll need to update the whole 1311 tree for anything to work. 1312 131320000928: 1314 There was a change in the passwd format. Need more information. 1315 131620000916: 1317 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken 1318 place. Please update boot loader (not the boot blocks) at the 1319 same time as your kernel. 1320 132120000914: 1322 The new pmtimer device is necessary for laptops. Failure to 1323 include the device will cause suspended laptops losing time 1324 when they resume. Include 1325 device pmtimer 1326 in your config file and 1327 hint.pmtimer.0.at="isa" 1328 to your /boot/device.hints file. 1329 133020000911: 1331 The random device has been turned into a (pseudo-)device, 1332 rather than an option. The supplied kernel config files have 1333 been updated. You will need to do something similar in your 1334 own kernel config file. 1335 Remove: 1336 options RANDOMDEV 1337 Add: 1338 device random 1339 If you prefer to load the loadable module, you need to do 1340 nothing. 1341 134220000909: 1343 The random device module has been renamed from randomdev.ko to 1344 random.ko. You will need to edit your /boot/loader.conf to 1345 reflect this if you load this module at boot time. 1346 The line should read: 1347 random_load="YES" 1348 134920000907: 1350 The SMPNG commit has happened. It should work, but if it 1351 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely 1352 to be a variety of minor issues. Please see 20000905 to make 1353 sure you don't have model loading problems which might at 1354 first blush appear related to SMP. 1355 135620000906: 1357 nsswitch has been imported from NetBSD. Among other things, 1358 this means that /etc/host.conf is no longer used. See 1359 nsswitch.conf(5) instead. Note that at boot time rc.network 1360 will attempt to produce a new nsswitch.conf file for you if you 1361 don't have one, and you have host.conf. 1362 136320000905: 1364 The ucred structure changed size. This breaks the interface 1365 that mountd uses. Trying to use an older mountd with a newer 1366 kernel guarantees a panic. This means that you need to use 1367 kernels newer than today only with matching mountd, but you 1368 needed to do that anyway with the boot loader changes. 1369 137020000905: 1371 The boot loader has been updated. The new default kernel is 1372 now /boot/kernel/kernel.ko. The new default module location 1373 is /boot/kernel. 1374 1375 You *MUST* upgrade your boot loader and kernel at the same time. 1376 The easiest way to do this is to do the buildworld/buildkernel/ 1377 installkernel/installworld dance. 1378 1379 Furthermore, you are urged to delete your old /modules directory 1380 before booting the new kernel, since kldload will find stale 1381 modules in that directory instead of finding them in the correct 1382 path, /boot/kernel. The most common complaint that this cures 1383 is that the linux module crashes your machine after the update. 1384 1385 if [ ! -d /boot/kernel.old ]; then 1386 mv /modules.old /boot/kernel.old 1387 chflags noschg /kernel.old 1388 mv /kernel.old /boot/kernel.old/kernel.ko 1389 chflags schg /boot/kernel.old/kernel.ko 1390 fi 1391 139220000904: 1393 A new issue with the sendmail upgrade has come to light. 1394 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will 1395 incorrectly install the default aliases in /etc/mail rather than 1396 move the old one from /etc. So you'll need to manually move the 1397 file, create a symbolic link, remove the old /etc/aliases.db and 1398 run newaliases. For safety sake, you should stop sendmail 1399 while doing this and run the upgrade when locally sourced email 1400 is not likely to be generated. 1401 140220000825: 1403 /boot/device.hints is now required for installkernel to 1404 succeed. You should copy GENERIC.hints for your architecture 1405 into /boot/device.hints. If and only if you compile hints 1406 into your kernel, then this file may be empty. Please note, 1407 if you have an empty or missing /boot/device.hints file and 1408 you neglected to compile hints into your kernel, no boot 1409 messages will appear after the boot loader tries to start the 1410 kernel. 1411 141220000821: 1413 If you do NOT have ``options RANDOMDEV'' in your kernel and 1414 you DO want the random device then add randomdev_load="YES" to 1415 /boot/loader.conf. 1416 141720000812: 1418 suidperl is now always built and installed on the system, but 1419 with permissions of 511. If you have applications that use 1420 this program, you are now required to add ENABLE_SUIDPERL=true 1421 to /etc/make.conf. If you forget to do this, 1422 chmod 4511 /usr/bin/suidperl 1423 will fix this until the next build. 1424 142520000812: 1426 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more 1427 visible changes that may immediately affect your configuration 1428 include: 1429 - New default file locations from src/contrib/sendmail/cf/README 1430 - newaliases limited to root and trusted users 1431 - MSA port (587) turned on by default 1432 - New queue file naming system so can't go from 8.11 -> 8.9 1433 - FEATURE(`rbl') renamed to FEATURE(`dnsbl') 1434 - FEATURE(`nullclient') is more full featured 1435 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial' 1436 - mail.local FreeBSD-only -b option changed to -B 1437 - See src/contrib/sendmail/RELEASE_NOTES for more info 1438 143920000810: 1440 suidperl (aka sperl) is no longer build by default. You must 1441 specifically define BUILD_SUIDPERL to "true" for it to be build. 1442 Furthermore, we recommend that you remove /usr/bin/sperl* and 1443 /usr/bin/suidperl files from your system unless you have a 1444 specific use for it. 1445 144620000729: 1447 Networking defaults have been tightened. Anybody upgrading 1448 /etc/defaults/rc.conf needs to add the following lines to 1449 /etc/rc.conf if they want to have the same setup 1450 afterwards (unless the variables already are set, of course): 1451 # Enable network daemons for user convenience. 1452 inetd_enable="YES" 1453 portmap_enable="YES" 1454 sendmail_enable="YES" 1455 145620000728: 1457 If you have null_load="YES" in your /boot/loader.conf, you 1458 will need to change that to nullfs_load="YES". 1459 146020000728: 1461 The "installkernel" target has changed slightly. Now even if 1462 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL' 1463 it will install the MYKERNEL file (built with the buildkernel 1464 target) as /kernel rather than /MYKERNEL. Those who have 1465 updated their /boot/loader.conf files to point to /MYKERNEL 1466 should remove that entry or perform manual rename of /kernel 1467 to /MYKERNEL. 1468 146920000711: 1470 If you use CVSUP or CTM to get CVS trees, AND you used to get 1471 the old crypto files from internat.freebsd.org AND you check 1472 out files from the CVS tree with the cvs command, please read 1473 http://people.freebsd.org/~imp/internat.txt 1474 for details on potential problems that you might have and how 1475 to get around them. 1476 1477 If you are merely a mirror, or don't answer yes to each of the 1478 clauses above, you needn't worry. 1479 148020000711: 1481 /etc/security has been updated to print the inode number of 1482 setuid programs that have changed. You will see a large spike 1483 in the number of changed programs the first time when you run 1484 mergemaster to get a new /etc/security. 1485 148620000710: 1487 /dev/random now has good entropy collection (from the keyboard 1488 and sysmouse drivers). Please ensure that either `options 1489 RANDOMDEV' is present in your kernel config file or that 1490 `randomdev_load="YES"' is in your /boot/loader.conf. If you do 1491 not have the /dev/random driver, OpenSSL (and consequently 1492 lots of crypto tools (like SSH)) will fail with strange 1493 errors. (see below, 20000624). 1494 1495 FreeBSD-current is safe again to run Crypto. 1496 149720000709: 1498 phk made the malloc default options AJ. This may slow things 1499 down and uncover other latent bugs in the code. If you need to 1500 run at full speed, you can disable this by doing the following: 1501 ln -s aj /etc/malloc.conf 1502 150320000706: 1504 libftpio's version was accidentally bumped a few days ago. This 1505 has been corrected. You may need to remove /usr/lib/libftpio.so.6 1506 before doing your next buildworld/installworld pair. It certainly 1507 won't hurt to remove it before the update procedure. It will 1508 break fetch until a new one is built, but ftp can be used in the 1509 interim if needed. 1510 151120000705: 1512 The crypto packages have changed for the cvsup. This has been done 1513 in a backward compatible way, but the old packages will go away at 1514 some point in the future. Look at /usr/share/examples/cvsup for 1515 details. 1516 151720000704: 1518 With the new sys/modules/sound/drivers/*, you will need to 1519 set SYSDIR until you do an installworld after July 7th. 1520 152120000704: 1522 rc.shutdown and rc will now call the rc.d scripts with start 1523 or stop. This may cause some harmless warnings from older 1524 rc.d scripts that haven't been updated. 1525 152620000630: 1527 The libfetch based version of fetch has gone into the tree. 1528 Minor problems may result on some of the less popular sites, 1529 which should be reported to des@freebsd.org. 1530 153120000625: 1532 From approximately this date forward, one must have the crypto 1533 system installed in order to build the system and kernel. 1534 While not technically strictly true, one should treat it as 1535 required and grab the crypto bits. If you are grabbing CVS 1536 trees, src-all and cvs-crypto should be treated as if they 1537 were required. You should check with the latest collections 1538 to make sure that these haven't changed. 1539 154020000624: 1541 Mark Murray just committed the first parts of a cleanup of 1542 /dev/zero, et al. This is also cleaning up /dev/random. 1543 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD 1544 -CURRENT FROM THIS POINT to 2000710 for cryptographic services 1545 until Mark can merge in the fixes to this work in progress. 1546 openssh and openssl should not be used to generate keys from this 1547 date to the completion of the work. 1548 1549 If you must operate at this reduced level of security, add ' 1550 options RANDOMDEV' to your kernel or modload the randomdev 1551 module. You may also need to copy a new MAKEDEV to /dev and 1552 recreate the random and urandom devices. 1553 155420000622: 1555 The license on the softupdates is now a standard 2 clause 1556 BSD license. You may need to remove your symbolic links 1557 that used to be required when updating. 1558 155920000621: 1560 Scott Flatman <sf@aracnet.com> sent in a decent write-up on 1561 the config file update procedure. 1562 http://people.freebsd.org/~imp/config-upd.html 1563 NOTE: LINT is gone. It has been replaced with NOTES. NOTES 1564 isn't buildable. However, you can generate a LINT file: 1565 cd /sys/<ARCH>/conf && make LINT 1566 156720000620: 1568 Binutils 2.10 have hit the tree, or will shortly. As soon 1569 as they do, the problem noted in 20000522 will be resolved and 1570 that workaround will no longer be required. 1571 157220000615: 1573 phk removed the compatibility creation of wd devices in the 1574 ad driver. If you haven't done so already, you must update 1575 your fstab, etc to use the ad devices instead of the wd 1576 devices. 1577 1578 In addition, you'll need to update your boot blocks to a 1579 more modern version, if you haven't already done so. Modern 1580 here means 4.0 release or newer (although older releases 1581 may work). 1582 158320000612: 1584 Peter took an axe to config(8). Be sure that you read his mail 1585 on the topic before even thinking about updating. You will 1586 need to create a /boot/device.hints or add a hints directive 1587 to your config file to compile them in statically. The format 1588 of the config file has changed as well. Please see GENERIC or 1589 NEWCARD for examples of the new format. 1590 1591 Indirectly, this also breaks USERCONFIG. Unless a newer entry 1592 says that it has been fixed, assume that must use the hints mechanism 1593 in the loader if you need to use a machine with very old ISA cards 1594 in it. 1595 159620000522: 1597 A new set of binutils went into the tree today. Anybody 1598 building a kernel after this point is advised that they need 1599 to rebuild their binutils (or better yet do a 1600 buildworld/installworld) before building a new kernel. 1601 1602 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf 1603 or MALLOC_OPTIONS env var) J will cause ld to dump core. It 1604 is recommended that you don't set this option until the problem 1605 is resolved. 1606 160720000513: 1608 The ethernet drivers were all updated to clean up the BPF handling. 1609 161020000510: 1611 The problems with boot blocks on the alphas have been corrected. 1612 This will require some care in updating alphas. A new libstand 1613 is requires for the boot blocks to build properly. 1614 161520000503: 1616 Recompile all kld modules. Proper version dependency info 1617 is now available. 1618 161920000502: 1620 Modules have been disconnected from the buildworld tree and 1621 connected to the kernel building instead. 1622 162320000427: 1624 You may need to build gperf 1625 cd /usr/src/gnu/usr.bin/gperf && make depend all install 1626 when upgrading from 4.0 -> current. The build system now uses 1627 an option only in -current. 1628 162920000417: 1630 The method that we brand ELF binaries has changed to be more 1631 acceptable to the binutils maintainers. You will need to 1632 rebrand your ELF binaries that aren't native. One problem 1633 binary is the Linux ldconfig. After your make world, but 1634 before you reboot, you'll need to issue: 1635 brandelf -t Linux /compat/linux/sbin/ldconfig 1636 if you have Linux compatibility enabled on your machine. 1637 163820000320: 1639 If you have really bad/marginal IDE drives, you may find they 1640 don't work well. Use pio mode instead. The easiest way to 1641 cope if you have a problem combination is to add: 1642 /sbin/sysctl hw.ata.ata_dma=0 1643 to the start of /etc/rc.conf. 1644 164520000319: 1646 The ISA and PCI compatibility shims have been connected to the 1647 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old 1648 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must 1649 include the appropriate option in your kernel config. Drivers 1650 using the shims should be updated or they won't ship with 1651 5.0-RELEASE, targeted for 2001. 1652 165320000318: 1654 We've entered the traditional post release dumping party. 1655 Large kernel changes are being committed and are in the 1656 works. It is important to keep the systems' klds and kernel 1657 in sync as kernel interfaces and structures are changing. 1658 Before reporting kernel panics, make sure that all modules 1659 that you are loading are up to date. 1660 166120000315: 1662 If you are upgrading from an older version of FreeBSD, you 1663 need to update your boot blocks as well. 'disklabel -B ad0' 1664 will do the trick. This isn't critical until you remove your 1665 wd device entries in /dev, at which point your system will not 1666 boot. 1667 166820000315: 1669 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how 1670 to upgrade to 4.0 from 3.x. 1671 1672COMMON ITEMS: 1673 1674 # NOTE: 5.x below applies to 6.0-currrent as well, for the 1675 # momemnt. 4.any -> 5.any upgrade support will remain in 1676 # place for 6.0 current, but after 5.3 RELEASE, the 4.any -> 1677 # 6.0-current upgrade path will require moving through 5.3 1678 # RELEASE or newer. 1679 1680 General Notes 1681 ------------- 1682 Avoid using make -j when upgrading. From time to time in the 1683 past there have been problems using -j with buildworld and/or 1684 installworld. This is especially true when upgrading between 1685 "distant" versions (eg one that cross a major release boundary 1686 or several minor releases, or when several months have passed 1687 on the -current branch). 1688 1689 Sometimes, obscure build problems are the result of environment 1690 poisoning. This can happen because the make utility reads its 1691 environment when searching for values for global variables. 1692 To run your build attempts in an "environmental clean room", 1693 prefix all make commands with 'env -i '. See the env(1) manual 1694 page for more details. 1695 1696 To build a kernel 1697 ----------------- 1698 If you are updating from a prior version of FreeBSD (even one just 1699 a few days old), you should follow this procedure. With a 1700 /usr/obj tree with a fresh buildworld, 1701 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1702 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1703 1704 To just build a kernel when you know that it won't mess you up 1705 -------------------------------------------------------------- 1706 This assumes you are already running a 5.X system. Replace 1707 ${arch} with the architecture of your machine (e.g. "i386", 1708 "alpha", "amd64", "ia64", "pc98", "sparc64", etc). 1709 1710 cd src/sys/${arch}/conf 1711 config KERNEL_NAME_HERE 1712 cd ../compile/KERNEL_NAME_HERE 1713 make depend 1714 make 1715 make install 1716 1717 If this fails, go to the "To build a kernel" section. 1718 1719 To rebuild everything and install it on the current system. 1720 ----------------------------------------------------------- 1721 # Note: sometimes if you are running current you gotta do more than 1722 # is listed here if you are upgrading from a really old current. 1723 1724 <make sure you have good level 0 dumps> 1725 <maybe fix /etc/fstab> [7] 1726 make buildworld 1727 make kernel KERNCONF=YOUR_KERNEL_HERE 1728 [1] 1729 <reboot in single user> [3] 1730 src/etc/rc.d/preseedrandom [10] 1731 mergemaster -p [5] 1732 make installworld 1733 mergemaster [4] 1734 <reboot> 1735 1736 1737 To cross-install current onto a separate partition 1738 -------------------------------------------------- 1739 # In this approach we use a separate partition to hold 1740 # current's root, 'usr', and 'var' directories.

Also, the location of kernel 1766 # modules has changed. If you are installing 5.x onto a 4.x 1767 # system, you'll need about 30MB of free disk space on your / 1768 # partition. If you have less than this, you may encounter difficult 1769 # to back out of problems with this procedure. If /tmp is on 1770 # the / partition, you may want to completely remove all its content 1771 # before upgrading, as this can be a common source of shortage of 1772 # space on /. 1773 1774 <make sure you have good level 0 dumps> 1775 <maybe fix /etc/fstab> [7] 1776 make buildworld [9] 1777 cp sys/${MACHINE}/conf/GENERIC.hints /boot/device.hints [2] 1778 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1779 cd sys/boot ; make STRIP="" install [6] 1780 [1] 1781 <reboot in single user> [3] 1782 src/etc/rc.d/preseedrandom [10] 1783 mergemaster -p [5] 1784 rm -rf /usr/include/g++ 1785 make installworld 1786 mergemaster -i [4] 1787 <reboot> 1788 1789 Make sure that you've read the UPDATING file to understand the 1790 tweaks to various things you need. At this point in the life 1791 cycle of current, things change often and you are on your own 1792 to cope. The defaults can also change, so please read ALL of 1793 the UPDATING entries. 1794 1795 Also, if you are tracking -current, you must be subscribed to 1796 freebsd-current@freebsd.org. Make sure that before you update 1797 your sources that you have read and understood all the recent 1798 messages there. If in doubt, please track -stable which has 1799 much fewer pitfalls. 1800 1801 [1] If you have third party modules, such as vmware, you 1802 should disable them at this point so they don't crash your 1803 system on reboot. 1804 1805 [2] If you have legacy ISA devices, you may need to create 1806 your own device.hints to reflect your unique hardware 1807 configuration. 1808 1809 [3] From the bootblocks, boot -s, and then do 1810 fsck -p 1811 mount -u / 1812 mount -a 1813 cd src 1814 adjkerntz -i # if CMOS is wall time 1815 Also, when doing a major release upgrade, it is required that 1816 you boot into single user mode to do the installworld. 1817 For the 4.x -> 5.x upgrade, you will also see many messages about 1818 needing to recompile your userland. These are harmless and can 1819 be ignored while you proceed to the next step. 1820 1821 [4] Note: This step is non-optional. Failure to do this step 1822 can result in a significant reduction in the functionality of the 1823 system. Attempting to do it by hand is not recommended and those 1824 that pursue this avenue should read this file carefully, as well 1825 as the archives of freebsd-current and freebsd-hackers mailing lists 1826 for potential gotchas. 1827 1828 [5] Usually this step is a noop. However, from time to time 1829 you may need to do this if you get unknown user in the following 1830 step. It never hurts to do it all the time. You may need to 1831 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1832 install) after the buildworld before this step if you last updated 1833 from current before 20020224 or from -stable before 20020408. 1834 1835 [6] 4.x boot loader can be used to boot a 5.x system, however 1836 it is difficult to do that at best. If you wish to try, then 1837 you should interrupt the boot and at the ok prompt type: 1838 ok unload 1839 ok boot /boot/kernel/kernel 1840 If this fails to work, you must install a new boot loader as 1841 described here. 1842 1843 [7] Before you upgrade, please make sure that you are not using 1844 compatibility slices. These are device names of the form /dev/ad0a 1845 without the actual slice name. These will break with 5.x and newer. 1846 You generally must update these entries to use the post FreeBSD 1847 2.x form of /dev/ad0s1a. i386 and pc98 are affected, while alpha 1848 is not. 1849 1850 [8] In order to have a kernel that can run the 4.x binaries 1851 needed to do an installworld, you must include the COMPAT_FREEBSD4 1852 option in your kernel. Failure to do so may leave you with a system 1853 that is hard to boot to recover. 1854 1855 Make sure that you merge any new devices from GENERIC since the 1856 last time you updated your kernel config file. 1857 1858 [9] When checking out sources, you must include the -P flag to have 1859 cvs prune empty directories. 1860 1861 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1862 "?=" instead of the "=" assignment operator, so that buildworld can 1863 override the CPUTYPE if it needs to. 1864 1865 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1866 not on the command line, or in /etc/make.conf. buildworld will 1867 warn if it is improperly defined. 1868 1869 In case you would like to avoid installing new packages of everything, 1870 you might want to uncomment the "COMPAT4X= YES" entry, so that 4.x 1871 compatibility libraries are built which should allow you to continue 1872 using your existing software for a while. Alternatively, you can 1873 install the misc/compat4x port. 1874 1875 [10] In order to create temporary files, /dev/random must be 1876 initialized by feeding data into it. src/etc/rc.d/preseedrandom 1877 takes care of this. 1878FORMAT: 1879 1880This file contains a list, in reverse chronological order, of major 1881breakages in tracking -current. Not all things will be listed here, 1882and it only starts on March 15, 2000. Updating files can found in 1883previous releases if your system is older than this. 1884 1885Copyright information: 1886 1887Copyright 1998-2004 M. Warner Losh.
