Please read that file before running 9portupgrade. 10 11NOTE TO PEOPLE WHO THINK THAT FreeBSD 8.x IS SLOW: 12 FreeBSD 8.x has many debugging features turned on, in 13 both the kernel and userland. These features attempt to detect 14 incorrect use of system primitives, and encourage loud failure 15 through extra sanity checking and fail stop semantics. They 16 also substantially impact system performance. If you want to 17 do performance measurement, benchmarking, and optimization, 18 you'll want to turn them off. This includes various WITNESS- 19 related kernel options, INVARIANTS, malloc debugging flags 20 in userland, and various verbose features in the kernel. Many 21 developers choose to disable these features on build machines 22 to maximize performance. (To disable malloc debugging, run 23 ln -s aj /etc/malloc.conf.) 24 2520090115: 26 TCP Appropriate Byte Counting (RFC 3465) support added to kernel. 27 New field in struct tcpcb breaks ABI, so bump __FreeBSD_version to 28 800061. User space tools that rely on the size of struct tcpcb in 29 tcp_var.h (e.g. sockstat) need to be recompiled. 30 3120081225: 32 ng_tty(4) module updated to match the new TTY subsystem. 33 Due to API change, user-level applications must be updated. 34 New API support added to mpd5 CVS and expected to be present 35 in next mpd5.3 release. 36 3720081219: 38 With __FreeBSD_version 800060 the makefs tool is part of 39 the base system (it was a port). 40 4120081216: 42 The afdata and ifnet locks have been changed from mutexes to 43 rwlocks, network modules will need to be re-compiled. 44 4520081214: 46 __FreeBSD_version 800059 incorporates the new arp-v2 rewrite. 47 RTF_CLONING, RTF_LLINFO and RTF_WASCLONED flags are eliminated. 48 The new code reduced struct rtentry{} by 16 bytes on 32-bit 49 architecture and 40 bytes on 64-bit architecture. The userland 50 applications "arp" and "ndp" have been updated accordingly. 51 The output from "netstat -r" shows only routing entries and 52 none of the L2 information. 53 5420081130: 55 __FreeBSD_version 800057 marks the switchover from the 56 binary ath hal to source code. Users must add the line: 57 58 options AH_SUPPORT_AR5416 59 60 to their kernel config files when specifying: 61 62 device ath_hal 63 64 The ath_hal module no longer exists; the code is now compiled 65 together with the driver in the ath module. It is now 66 possible to tailor chip support (i.e. reduce the set of chips 67 and thereby the code size); consult ath_hal(4) for details. 68 6920081121: 70 __FreeBSD_version 800054 adds memory barriers to 71 <machine/atomic.h>, new interfaces to ifnet to facilitate 72 multiple hardware transmit queues for cards that support 73 them, and a lock-less ring-buffer implementation to 74 enable drivers to more efficiently manage queueing of 75 packets. 76 7720081117: 78 A new version of ZFS (version 13) has been merged to -HEAD. 79 This version has zpool attribute "listsnapshots" off by 80 default, which means "zfs list" does not show snapshots, 81 and is the same as Solaris behavior. 82 8320081028: 84 dummynet(4) ABI has changed. ipfw(8) needs to be recompiled. 85 8620081009: 87 The uhci, ohci, ehci and slhci USB Host controller drivers have 88 been put into separate modules. If you load the usb module 89 separately through loader.conf you will need to load the 90 appropriate *hci module as well. E.g. for a UHCI-based USB 2.0 91 controller add the following to loader.conf: 92 93 uhci_load="YES" 94 ehci_load="YES" 95 9620081009: 97 The ABI used by the PMC toolset has changed. Please keep 98 userland (libpmc(3)) and the kernel module (hwpmc(4)) in 99 sync. 100 10120080820: 102 The TTY subsystem of the kernel has been replaced by a new 103 implementation, which provides better scalability and an 104 improved driver model. Most common drivers have been migrated to 105 the new TTY subsystem, while others have not. The following 106 drivers have not yet been ported to the new TTY layer: 107 108 PCI/ISA: 109 cy, digi, rc, rp, sio 110 111 USB: 112 ubser, ucycom 113 114 Line disciplines: 115 ng_h4, ng_tty, ppp, sl, snp 116 117 Adding these drivers to your kernel configuration file shall 118 cause compilation to fail. 119 12020080818: 121 ntpd has been upgraded to 4.2.4p5. 122 12320080801: 124 OpenSSH has been upgraded to 5.1p1. 125 126 For many years, FreeBSD's version of OpenSSH preferred DSA 127 over RSA for host and user authentication keys. With this 128 upgrade, we've switched to the vendor's default of RSA over 129 DSA. This may cause upgraded clients to warn about unknown 130 host keys even for previously known hosts. Users should 131 follow the usual procedure for verifying host keys before 132 accepting the RSA key. 133 134 This can be circumvented by setting the "HostKeyAlgorithms" 135 option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh 136 command line. 137 138 Please note that the sequence of keys offered for 139 authentication has been changed as well. You may want to 140 specify IdentityFile in a different order to revert this 141 behavior. 142 14320080713: 144 The sio(4) driver has been removed from the i386 and amd64 145 kernel configuration files. This means uart(4) is now the 146 default serial port driver on those platforms as well. 147 148 To prevent collisions with the sio(4) driver, the uart(4) driver 149 uses different names for its device nodes. This means the 150 onboard serial port will now most likely be called "ttyu0" 151 instead of "ttyd0". You may need to reconfigure applications to 152 use the new device names. 153 154 When using the serial port as a boot console, be sure to update 155 /boot/device.hints and /etc/ttys before booting the new kernel. 156 If you forget to do so, you can still manually specify the hints 157 at the loader prompt: 158 159 set hint.uart.0.at="isa" 160 set hint.uart.0.port="0x3F8" 161 set hint.uart.0.flags="0x10" 162 set hint.uart.0.irq="4" 163 boot -s 164 16520080609: 166 The gpt(8) utility has been removed. Use gpart(8) to partition 167 disks instead. 168 16920080603: 170 The version that Linuxulator emulates was changed from 2.4.2 171 to 2.6.16. If you experience any problems with Linux binaries 172 please try to set sysctl compat.linux.osrelease to 2.4.2 and 173 if it fixes the problem contact emulation mailing list. 174 17520080525: 176 ISDN4BSD (I4B) was removed from the src tree. You may need to 177 update a your kernel configuration and remove relevant entries. 178 17920080509: 180 I have checked in code to support multiple routing tables. 181 See the man pages setfib(1) and setfib(2). 182 This is a hopefully backwards compatible version, 183 but to make use of it you need to compile your kernel 184 with options ROUTETABLES=2 (or more up to 16). 185 18620080420: 187 The 802.11 wireless support was redone to enable multi-bss 188 operation on devices that are capable. The underlying device 189 is no longer used directly but instead wlanX devices are 190 cloned with ifconfig. This requires changes to rc.conf files. 191 For example, change: 192 ifconfig_ath0="WPA DHCP" 193 to 194 wlans_ath0=wlan0 195 ifconfig_wlan0="WPA DHCP" 196 see rc.conf(5) for more details. In addition, mergemaster of 197 /etc/rc.d is highly recommended. Simultaneous update of userland 198 and kernel wouldn't hurt either. 199 200 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta 201 modules were merged into the base wlan module. All references 202 to these modules (e.g. in kernel config files) must be removed. 203 20420080408: 205 psm(4) has gained write(2) support in native operation level. 206 Arbitrary commands can be written to /dev/psm%d and status can 207 be read back from it. Therefore, an application is responsible 208 for status validation and error recovery. It is a no-op in 209 other operation levels. 210 21120080312: 212 Support for KSE threading has been removed from the kernel. To 213 run legacy applications linked against KSE libmap.conf may 214 be used. The following libmap.conf may be used to ensure 215 compatibility with any prior release: 216 217 libpthread.so.1 libthr.so.1 218 libpthread.so.2 libthr.so.2 219 libkse.so.3 libthr.so.3 220 22120080301: 222 The layout of struct vmspace has changed. This affects libkvm 223 and any executables that link against libkvm and use the 224 kvm_getprocs() function. In particular, but not exclusively, 225 it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1). 226 The effects are minimal, but it's advisable to upgrade world 227 nonetheless. 228 22920080229: 230 The latest em driver no longer has support in it for the 231 82575 adapter, this is now moved to the igb driver. The 232 split was done to make new features that are incompatible 233 with older hardware easier to do. 234 23520080220: 236 The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4), 237 likewise the kernel option is now GEOM_LINUX_LVM. 238 23920080211: 240 The default NFS mount mode has changed from UDP to TCP for 241 increased reliability. If you rely on (insecurely) NFS 242 mounting across a firewall you may need to update your 243 firewall rules. 244 24520080208: 246 Belatedly note the addition of m_collapse for compacting 247 mbuf chains. 248 24920080126: 250 The fts(3) structures have been changed to use adequate 251 integer types for their members and so to be able to cope 252 with huge file trees. The old fts(3) ABI is preserved 253 through symbol versioning in libc, so third-party binaries 254 using fts(3) should still work, although they will not take 255 advantage of the extended types. At the same time, some 256 third-party software might fail to build after this change 257 due to unportable assumptions made in its source code about 258 fts(3) structure members. Such software should be fixed 259 by its vendor or, in the worst case, in the ports tree. 260 FreeBSD_version 800015 marks this change for the unlikely 261 case that a portable fix is impossible. 262 26320080123: 264 To upgrade to -current after this date, you must be running 265 FreeBSD not older than 6.0-RELEASE. Upgrading to -current 266 from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems. 267 26820071128: 269 The ADAPTIVE_GIANT kernel option has been retired because its 270 functionality is the default now. 271 27220071118: 273 The AT keyboard emulation of sunkbd(4) has been turned on 274 by default. In order to make the special symbols of the Sun 275 keyboards driven by sunkbd(4) work under X these now have 276 to be configured the same way as Sun USB keyboards driven 277 by ukbd(4) (which also does AT keyboard emulation), f.e.: 278 279 Option "XkbLayout" "us" 280 Option "XkbRules" "xorg" 281 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 282 28320071024: 284 It has been decided that it is desirable to provide ABI 285 backwards compatibility to the FreeBSD 4/5/6 versions of the 286 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 287 broken with the introduction of PCI domain support (see the 288 20070930 entry). Unfortunately, this required the ABI of 289 PCIOCGETCONF to be broken again in order to be able to 290 provide backwards compatibility to the old version of that 291 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 292 again. As for prominent ports this affects neither pciutils 293 nor xorg-server this time, the hal port needs to be rebuilt 294 however. 295 29620071020: 297 The misnamed kthread_create() and friends have been renamed 298 to kproc_create() etc. Many of the callers already 299 used kproc_start().. 300 I will return kthread_create() and friends in a while 301 with implementations that actually create threads, not procs. 302 Renaming corresponds with version 800002. 303 30420071010: 305 RELENG_7 branched. 306 30720071009: 308 Setting WITHOUT_LIBPTHREAD now means WITHOUT_LIBKSE and 309 WITHOUT_LIBTHR are set. 310 31120070930: 312 The PCI code has been made aware of PCI domains. This means that 313 the location strings as used by pciconf(8) etc are now in the 314 following format: pci<domain>:<bus>:<device>[:<function>]. It 315 also means that consumers of <sys/pciio.h> potentially need to 316 be recompiled; this includes the hal and xorg-server ports. 317 31820070928: 319 The caching daemon (cached) was renamed to nscd. nscd.conf 320 configuration file should be used instead of cached.conf and 321 nscd_enable, nscd_pidfile and nscd_flags options should be used 322 instead of cached_enable, cached_pidfile and cached_flags in 323 rc.conf. 324 32520070921: 326 The getfacl(1) utility now prints owning user and group name 327 instead of owning uid and gid in the three line comment header. 328 This is the same behavior as getfacl(1) on Solaris and Linux. 329 33020070704: 331 The new IPsec code is now compiled in using the IPSEC option. The 332 IPSEC option now requires "device crypto" be defined in your kernel 333 configuration. The FAST_IPSEC kernel option is now deprecated. 334 33520070702: 336 The packet filter (pf) code has been updated to OpenBSD 4.1 Please 337 note the changed syntax - keep state is now on by default. Also 338 note the fact that ftp-proxy(8) has been changed from bottom up and 339 has been moved from libexec to usr/sbin. Changes in the ALTQ 340 handling also affect users of IPFW's ALTQ capabilities. 341 34220070701: 343 Remove KAME IPsec in favor of FAST_IPSEC, which is now the 344 only IPsec supported by FreeBSD. The new IPsec stack 345 supports both IPv4 and IPv6. The kernel option will change 346 after the code changes have settled in. For now the kernel 347 option IPSEC is deprecated and FAST_IPSEC is the only option, that 348 will change after some settling time. 349 35020070701: 351 The wicontrol(8) utility has been removed from the base system. wi(4) 352 cards should be configured using ifconfig(8), see the man page for more 353 information. 354 35520070612: 356 The i386/amd64 GENERIC kernel now defaults to the nfe(4) driver 357 instead of the nve(4) driver. Please update your configuration 358 accordingly. 359 36020070612: 361 By default, /etc/rc.d/sendmail no longer rebuilds the aliases 362 database if it is missing or older than the aliases file. If 363 desired, set the new rc.conf option sendmail_rebuild_aliases 364 to "YES" to restore that functionality. 365 36620070612: 367 The IPv4 multicast socket code has been considerably modified, and 368 moved to the file sys/netinet/in_mcast.c. Initial support for the 369 RFC 3678 Source-Specific Multicast Socket API has been added to 370 the IPv4 network stack. 371 372 Strict multicast and broadcast reception is now the default for 373 UDP/IPv4 sockets; the net.inet.udp.strict_mcast_mship sysctl variable 374 has now been removed. 375 376 The RFC 1724 hack for interface selection has been removed; the use 377 of the Linux-derived ip_mreqn structure with IP_MULTICAST_IF has 378 been added to replace it. Consumers such as routed will soon be 379 updated to reflect this. 380 381 These changes affect users who are running routed(8) or rdisc(8) 382 from the FreeBSD base system on point-to-point or unnumbered 383 interfaces. 384 38520070610: 386 The net80211 layer has changed significantly and all wireless 387 drivers that depend on it need to be recompiled. Further these 388 changes require that any program that interacts with the wireless 389 support in the kernel be recompiled; this includes: ifconfig, 390 wpa_supplicant, hostapd, and wlanstats. Users must also, for 391 the moment, kldload the wlan_scan_sta and/or wlan_scan_ap modules 392 if they use modules for wireless support. These modules implement 393 scanning support for station and ap modes, respectively. Failure 394 to load the appropriate module before marking a wireless interface 395 up will result in a message to the console and the device not 396 operating properly. 397 39820070610: 399 The pam_nologin(8) module ceases to provide an authentication 400 function and starts providing an account management function. 401 Consequent changes to /etc/pam.d should be brought in using 402 mergemaster(8). Third-party files in /usr/local/etc/pam.d may 403 need manual editing as follows. Locate this line (or similar): 404 405 auth required pam_nologin.so no_warn 406 407 and change it according to this example: 408 409 account required pam_nologin.so no_warn 410 411 That is, the first word needs to be changed from "auth" to 412 "account". The new line can be moved to the account section 413 within the file for clarity. Not updating pam.conf(5) files 414 will result in nologin(5) ignored by the respective services. 415 41620070529: 417 The ether_ioctl() function has been synchronized with ioctl(2) 418 and ifnet.if_ioctl. Due to that, the size of one of its arguments 419 has changed on 64-bit architectures. All kernel modules using 420 ether_ioctl() need to be rebuilt on such architectures. 421 42220070516: 423 Improved INCLUDE_CONFIG_FILE support has been introduced to the 424 config(8) utility. In order to take advantage of this new 425 functionality, you are expected to recompile and install 426 src/usr.sbin/config. If you don't rebuild config(8), and your 427 kernel configuration depends on INCLUDE_CONFIG_FILE, the kernel 428 build will be broken because of a missing "kernconfstring" 429 symbol. 430 43120070513: 432 Symbol versioning is enabled by default. To disable it, use 433 option WITHOUT_SYMVER. It is not advisable to attempt to 434 disable symbol versioning once it is enabled; your installworld 435 will break because a symbol version-less libc will get installed 436 before the install tools. As a result, the old install tools, 437 which previously had symbol dependencies to FBSD_1.0, will fail 438 because the freshly installed libc will not have them. 439 440 The default threading library (providing "libpthread") has been 441 changed to libthr. If you wish to have libkse as your default, 442 use option DEFAULT_THREAD_LIB=libkse for the buildworld. 443 44420070423: 445 The ABI breakage in sendmail(8)'s libmilter has been repaired 446 so it is no longer necessary to recompile mail filters (aka, 447 milters). If you recompiled mail filters after the 20070408 448 note, it is not necessary to recompile them again. 449 45020070417: 451 The new trunk(4) driver has been renamed to lagg(4) as it better 452 reflects its purpose. ifconfig will need to be recompiled. 453 45420070408: 455 sendmail(8) has been updated to version 8.14.1. Mail filters 456 (aka, milters) compiled against the libmilter included in the 457 base operating system should be recompiled. 458 45920070302: 460 Firmwares for ipw(4) and iwi(4) are now included in the base tree. 461 In order to use them one must agree to the respective LICENSE in 462 share/doc/legal and define legal.intel_<name>.license_ack=1 via 463 loader.conf(5) or kenv(1). Make sure to deinstall the now 464 deprecated modules from the respective firmware ports. 465 46620070228: 467 The name resolution/mapping functions addr2ascii(3) and ascii2addr(3) 468 were removed from FreeBSD's libc. These originally came from INRIA 469 IPv6. Nothing in FreeBSD ever used them. They may be regarded as 470 deprecated in previous releases. 471 The AF_LINK support for getnameinfo(3) was merged from NetBSD to 472 replace it as a more portable (and re-entrant) API. 473 47420070224: 475 To support interrupt filtering a modification to the newbus API 476 has occurred, ABI was broken and __FreeBSD_version was bumped 477 to 700031. Please make sure that your kernel and modules are in 478 sync. For more info: 479 http://docs.freebsd.org/cgi/mid.cgi?20070221233124.GA13941 480 48120070224: 482 The IPv6 multicast forwarding code may now be loaded into GENERIC 483 kernels by loading the ip_mroute.ko module. This is built into the 484 module unless WITHOUT_INET6 or WITHOUT_INET6_SUPPORT options are 485 set; see src.conf(5) for more information. 486 48720070214: 488 The output of netstat -r has changed. Without -n, we now only 489 print a "network name" without the prefix length if the network 490 address and mask exactly match a Class A/B/C network, and an entry 491 exists in the nsswitch "networks" map. 492 With -n, we print the full unabbreviated CIDR network prefix in 493 the form "a.b.c.d/p". 0.0.0.0/0 is always printed as "default". 494 This change is in preparation for changes such as equal-cost 495 multipath, and to more generally assist operational deployment 496 of FreeBSD as a modern IPv4 router. 497 49820070210: 499 PIM has been turned on by default in the IPv4 multicast 500 routing code. The kernel option 'PIM' has now been removed. 501 PIM is now built by default if option 'MROUTING' is specified. 502 It may now be loaded into GENERIC kernels by loading the 503 ip_mroute.ko module. 504 50520070207: 506 Support for IPIP tunnels (VIFF_TUNNEL) in IPv4 multicast routing 507 has been removed. Its functionality may be achieved by explicitly 508 configuring gif(4) interfaces and using the 'phyint' keyword in 509 mrouted.conf. 510 XORP does not support source-routed IPv4 multicast tunnels nor the 511 integrated IPIP tunneling, therefore it is not affected by this 512 change. The __FreeBSD_version macro has been bumped to 700030. 513 51420061221: 515 Support for PCI Message Signalled Interrupts has been 516 re-enabled in the bge driver, only for those chips which are 517 believed to support it properly. If there are any problems, 518 MSI can be disabled completely by setting the 519 'hw.pci.enable_msi' and 'hw.pci.enable_msix' tunables to 0 520 in the loader. 521 52220061214: 523 Support for PCI Message Signalled Interrupts has been 524 disabled again in the bge driver. Many revisions of the 525 hardware fail to support it properly. Support can be 526 re-enabled by removing the #define of BGE_DISABLE_MSI in 527 "src/sys/dev/bge/if_bge.c". 528 52920061214: 530 Support for PCI Message Signalled Interrupts has been added 531 to the bge driver. If there are any problems, MSI can be 532 disabled completely by setting the 'hw.pci.enable_msi' and 533 'hw.pci.enable_msix' tunables to 0 in the loader. 534 53520061205: 536 The removal of several facets of the experimental Threading 537 system from the kernel means that the proc and thread structures 538 have changed quite a bit. I suggest all kernel modules that might 539 reference these structures be recompiled.. Especially the 540 linux module. 541 54220061126: 543 Sound infrastructure has been updated with various fixes and 544 improvements. Most of the changes are pretty much transparent, 545 with exceptions of followings: 546 1) All sound driver specific sysctls (hw.snd.pcm%d.*) have been 547 moved to their own dev sysctl nodes, for example: 548 hw.snd.pcm0.vchans -> dev.pcm.0.vchans 549 2) /dev/dspr%d.%d has been deprecated. Each channel now has its 550 own chardev in the form of "dsp%d.<function>%d", where <function> 551 is p = playback, r = record and v = virtual, respectively. Users 552 are encouraged to use these devs instead of (old) "/dev/dsp%d.%d". 553 This does not affect those who are using "/dev/dsp". 554 55520061122: 556 geom(4)'s gmirror(8) class metadata structure has been 557 rev'd from v3 to v4. If you update across this point and 558 your metadata is converted for you, you will not be easily 559 able to downgrade since the /boot/kernel.old/geom_mirror.ko 560 kernel module will be unable to read the v4 metadata. You 561 can resolve this by doing from the loader(8) prompt: 562 563 set vfs.root.mountfrom="ufs:/dev/XXX" 564 565 where XXX is the root slice of one of the disks that composed 566 the mirror (i.e.: /dev/ad0s1a). You can then rebuild 567 the array the same way you built it originally. 568 56920061122: 570 The following binaries have been disconnected from the build: 571 mount_devfs, mount_ext2fs, mount_fdescfs, mount_procfs, mount_linprocfs, 572 and mount_std. The functionality of these programs has been 573 moved into the mount program. For example, to mount a devfs 574 filesystem, instead of using mount_devfs, use: "mount -t devfs". 575 This does not affect entries in /etc/fstab, since entries in 576 /etc/fstab are always processed with "mount -t fstype". 577 57820061113: 579 Support for PCI Message Signalled Interrupts on i386 and amd64 580 has been added to the kernel and various drivers will soon be 581 updated to use MSI when it is available. If there are any problems, 582 MSI can be disabled completely by setting the 'hw.pci.enable_msi' 583 and 'hw.pci.enable_msix' tunables to 0 in the loader. 584 58520061110: 586 The MUTEX_PROFILING option has been renamed to LOCK_PROFILING. 587 The lockmgr object layout has been changed as a result of having 588 a lock_object embedded in it. As a consequence all file system 589 kernel modules must be re-compiled. The mutex profiling man page 590 has not yet been updated to reflect this change. 591 59220061026: 593 KSE in the kernel has now been made optional and turned on by 594 default. Use 'nooption KSE' in your kernel config to turn it 595 off. All kernel modules *must* be recompiled after this change. 596 There-after, modules from a KSE kernel should be compatible with 597 modules from a NOKSE kernel due to the temporary padding fields 598 added to 'struct proc'. 599 60020060929: 601 mrouted and its utilities have been removed from the base system. 602 60320060927: 604 Some ioctl(2) command codes have changed. Full backward ABI 605 compatibility is provided if the "options COMPAT_FREEBSD6" is 606 present in the kernel configuration file. Make sure to add 607 this option to your kernel config file, or recompile X.Org 608 and the rest of ports; otherwise they may refuse to work. 609 61020060924: 611 tcpslice has been removed from the base system. 612 61320060913: 614 The sizes of struct tcpcb (and struct xtcpcb) have changed due to 615 the rewrite of TCP syncookies. Tools like netstat, sockstat, and 616 systat needs to be rebuilt. 617 61820060903: 619 libpcap updated to v0.9.4 and tcpdump to v3.9.4 620 62120060816: 622 The IPFIREWALL_FORWARD_EXTENDED option is gone and the behaviour 623 for IPFIREWALL_FORWARD is now as it was before when it was first 624 committed and for years after. The behaviour is now ON. 625 62620060725: 627 enigma(1)/crypt(1) utility has been changed on 64 bit architectures. 628 Now it can decrypt files created from different architectures. 629 Unfortunately, it is no longer able to decrypt a cipher text 630 generated with an older version on 64 bit architectures. 631 If you have such a file, you need old utility to decrypt it. 632 63320060709: 634 The interface version of the i4b kernel part has changed. So 635 after updating the kernel sources and compiling a new kernel, 636 the i4b user space tools in "/usr/src/usr.sbin/i4b" must also 637 be rebuilt, and vice versa. 638 63920060627: 640 The XBOX kernel now defaults to the nfe(4) driver instead of 641 the nve(4) driver. Please update your configuration 642 accordingly. 643 64420060514: 645 The i386-only lnc(4) driver for the AMD Am7900 LANCE and Am79C9xx 646 PCnet family of NICs has been removed. The new le(4) driver serves 647 as an equivalent but cross-platform replacement with the pcn(4) 648 driver still providing performance-optimized support for the subset 649 of AMD Am79C971 PCnet-FAST and greater chips as before. 650 65120060511: 652 The machdep.* sysctls and the adjkerntz utility have been 653 modified a bit. The new adjkerntz utility uses the new 654 sysctl names and sysctlbyname() calls, so it may be impossible 655 to run an old /sbin/adjkerntz utility in single-user mode 656 with a new kernel. Replace the `adjkerntz -i' step before 657 `make installworld' with: 658 659 /usr/obj/usr/src/sbin/adjkerntz/adjkerntz -i 660 661 and proceed as usual with the rest of the installworld-stage 662 steps. Otherwise, you risk installing binaries with their 663 timestamp set several hours in the future, especially if 664 you are running with local time set to GMT+X hours. 665 66620060412: 667 The ip6fw utility has been removed. The behavior provided by 668 ip6fw has been in ipfw2 for a good while and the rc.d scripts 669 have been updated to deal with it. There are some rules that 670 might not migrate cleanly. Use rc.firewall6 as a template to 671 rewrite rules. 672 67320060428: 674 The puc(4) driver has been overhauled. The ebus(4) and sbus(4) 675 attachments have been removed. Make sure to configure scc(4) 676 on sparc64. Note also that by default puc(4) will use uart(4) 677 and not sio(4) for serial ports because interrupt handling has 678 been optimized for multi-port serial cards and only uart(4) 679 implements the interface to support it. 680 68120060330: 682 The scc(4) driver replaces puc(4) for Serial Communications 683 Controllers (SCCs) like the Siemens SAB82532 and the Zilog 684 Z8530. On sparc64, it is advised to add scc(4) to the kernel 685 configuration to make sure that the serial ports remain 686 functional. 687 68820060317: 689 Most world/kernel related NO_* build options changed names. 690 New knobs have common prefixes WITHOUT_*/WITH_* (modelled 691 after FreeBSD ports) and should be set in /etc/src.conf 692 (the src.conf(5) manpage is provided). Full backwards 693 compatibility is maintained for the time being though it's 694 highly recommended to start moving old options out of the 695 system-wide /etc/make.conf file into the new /etc/src.conf 696 while also properly renaming them. More conversions will 697 likely follow. Posting to current@: 698 699 http://lists.freebsd.org/pipermail/freebsd-current/2006-March/061725.html 700 70120060305: 702 The NETSMBCRYPTO kernel option has been retired because its 703 functionality is always included in NETSMB and smbfs.ko now. 704 70520060303: 706 The TDFX_LINUX kernel option was retired and replaced by the 707 tdfx_linux device. The latter can be loaded as the 3dfx_linux.ko 708 kernel module. Loading it alone should suffice to get 3dfx support 709 for Linux apps because it will pull in 3dfx.ko and linux.ko through 710 its dependencies. 711 71220060204: 713 The 'audit' group was added to support the new auditing functionality 714 in the base system. Be sure to follow the directions for updating, 715 including the requirement to run mergemaster -p. 716 71720060201: 718 The kernel ABI to file system modules was changed on i386. 719 Please make sure that your kernel and modules are in sync. 720 72120060118: 722 This actually occured some time ago, but installing the kernel 723 now also installs a bunch of symbol files for the kernel modules. 724 This increases the size of /boot/kernel to about 67Mbytes. You 725 will need twice this if you will eventually back this up to kernel.old 726 on your next install. 727 If you have a shortage of room in your root partition, you should add 728 -DINSTALL_NODEBUG to your make arguments or add INSTALL_NODEBUG="yes" 729 to your /etc/make.conf. 730 73120060113: 732 libc's malloc implementation has been replaced. This change has the 733 potential to uncover application bugs that previously went unnoticed. 734 See the malloc(3) manual page for more details. 735 73620060112: 737 The generic netgraph(4) cookie has been changed. If you upgrade 738 kernel passing this point, you also need to upgrade userland 739 and netgraph(4) utilities like ports/net/mpd or ports/net/mpd4. 740 74120060106: 742 si(4)'s device files now contain the unit number. 743 Uses of {cua,tty}A[0-9a-f] should be replaced by {cua,tty}A0[0-9a-f]. 744 74520060106: 746 The kernel ABI was mostly destroyed due to a change in the size 747 of struct lock_object which is nested in other structures such 748 as mutexes which are nested in all sorts of other structures. 749 Make sure your kernel and modules are in sync. 750 75120051231: 752 The page coloring algorithm in the VM subsystem was converted 753 from tuning with kernel options to autotuning. Please remove 754 any PQ_* option except PQ_NOOPT from your kernel config. 755 75620051211: 757 The net80211-related tools in the tools/tools/ath directory 758 have been moved to tools/tools/net80211 and renamed with a 759 "wlan" prefix. Scripts that use them should be adjusted 760 accordingly. 761 76220051202: 763 Scripts in the local_startup directories (as defined in 764 /etc/defaults/rc.conf) that have the new rc.d semantics will 765 now be run as part of the base system rcorder. If there are 766 errors or problems with one of these local scripts, it could 767 cause boot problems. If you encounter such problems, boot in 768 single user mode, remove that script from the */rc.d directory. 769 Please report the problem to the port's maintainer, and the 770 freebsd-ports@freebsd.org mailing list. 771 77220051129: 773 The nodev mount option was deprecated in RELENG_6 (where it 774 was a no-op), and is now unsupported. If you have nodev or dev listed 775 in /etc/fstab, remove it, otherwise it will result in a mount error. 776 77720051129: 778 ABI between ipfw(4) and ipfw(8) has been changed. You need 779 to rebuild ipfw(8) when rebuilding kernel. 780 78120051108: 782 rp(4)'s device files now contain the unit number. 783 Uses of {cua,tty}R[0-9a-f] should be replaced by {cua,tty}R0[0-9a-f]. 784 78520051029: 786 /etc/rc.d/ppp-user has been renamed to /etc/rc.d/ppp. 787 Its /etc/rc.conf.d configuration file has been `ppp' from 788 the beginning, and hence there is no need to touch it. 789 79020051014: 791 Now most modules get their build-time options from the kernel 792 configuration file. A few modules still have fixed options 793 due to their non-conformant implementation, but they will be 794 corrected eventually. You may need to review the options of 795 the modules in use, explicitly specify the non-default options 796 in the kernel configuration file, and rebuild the kernel and 797 modules afterwards. 798 79920051001: 800 kern.polling.enable sysctl MIB is now deprecated. Use ifconfig(8) 801 to turn polling(4) on your interfaces. 802 80320050927: 804 The old bridge(4) implementation was retired. The new 805 if_bridge(4) serves as a full functional replacement. 806 80720050722: 808 The ai_addrlen of a struct addrinfo was changed to a socklen_t 809 to conform to POSIX-2001. This change broke an ABI 810 compatibility on 64 bit architecture. You have to recompile 811 userland programs that use getaddrinfo(3) on 64 bit 812 architecture. 813 81420050711: 815 RELENG_6 branched here. 816 81720050629: 818 The pccard_ifconfig rc.conf variable has been removed and a new 819 variable, ifconfig_DEFAULT has been introduced. Unlike 820 pccard_ifconfig, ifconfig_DEFAULT applies to ALL interfaces that 821 do not have ifconfig_ifn entries rather than just those in 822 removable_interfaces. 823 82420050616: 825 Some previous versions of PAM have permitted the use of 826 non-absolute paths in /etc/pam.conf or /etc/pam.d/* when referring 827 to third party PAM modules in /usr/local/lib. A change has been 828 made to require the use of absolute paths in order to avoid 829 ambiguity and dependence on library path configuration, which may 830 affect existing configurations. 831 83220050610: 833 Major changes to network interface API. All drivers must be 834 recompiled. Drivers not in the base system will need to be 835 updated to the new APIs. 836 83720050609: 838 Changes were made to kinfo_proc in sys/user.h. Please recompile 839 userland, or commands like `fstat', `pkill', `ps', `top' and `w' 840 will not behave correctly. 841 842 The API and ABI for hwpmc(4) have changed with the addition 843 of sampling support. Please recompile lib/libpmc(3) and 844 usr.sbin/{pmcstat,pmccontrol}. 845 84620050606: 847 The OpenBSD dhclient was imported in place of the ISC dhclient 848 and the network interface configuration scripts were updated 849 accordingly. If you use DHCP to configure your interfaces, you 850 must now run devd. Also, DNS updating was lost so you will need 851 to find a workaround if you use this feature. 852 853 The '_dhcp' user was added to support the OpenBSD dhclient. Be 854 sure to run mergemaster -p (like you are supposed to do every time 855 anyway). 856 85720050605: 858 if_bridge was added to the tree. This has changed struct ifnet. 859 Please recompile userland and all network related modules. 860 86120050603: 862 The n_net of a struct netent was changed to an uint32_t, and 863 1st argument of getnetbyaddr() was changed to an uint32_t, to 864 conform to POSIX-2001. These changes broke an ABI 865 compatibility on 64 bit architecture. With these changes, 866 shlib major of libpcap was bumped. You have to recompile 867 userland programs that use getnetbyaddr(3), getnetbyname(3), 868 getnetent(3) and/or libpcap on 64 bit architecture. 869 87020050528: 871 Kernel parsing of extra options on '#!' first lines of shell 872 scripts has changed. Lines with multiple options likely will 873 fail after this date. For full details, please see 874 http://people.freebsd.org/~gad/Updating-20050528.txt 875 87620050503: 877 The packet filter (pf) code has been updated to OpenBSD 3.7 878 Please note the changed anchor syntax and the fact that 879 authpf(8) now needs a mounted fdescfs(5) to function. 880 88120050415: 882 The NO_MIXED_MODE kernel option has been removed from the i386 883 amd64 platforms as its use has been superceded by the new local 884 APIC timer code. Any kernel config files containing this option 885 should be updated. 886 88720050227: 888 The on-disk format of LC_CTYPE files was changed to be machine 889 independent. Please make sure NOT to use NO_CLEAN buildworld 890 when crossing this point. Crossing this point also requires 891 recompile or reinstall of all locale depended packages. 892 89320050225: 894 The ifi_epoch member of struct if_data has been changed to 895 contain the uptime at which the interface was created or the 896 statistics zeroed rather then the wall clock time because 897 wallclock time may go backwards. This should have no impact 898 unless an snmp implementation is using this value (I know of 899 none at this point.) 900 90120050224: 902 The acpi_perf and acpi_throttle drivers are now part of the 903 acpi(4) main module. They are no longer built separately. 904 90520050223: 906 The layout of struct image_params has changed. You have to 907 recompile all compatibility modules (linux, svr4, etc) for use 908 with the new kernel. 909 91020050223: 911 The p4tcc driver has been merged into cpufreq(4). This makes 912 "options CPU_ENABLE_TCC" obsolete. Please load cpufreq.ko or 913 compile in "device cpufreq" to restore this functionality. 914 91520050220: 916 The responsibility of recomputing the file system summary of 917 a SoftUpdates-enabled dirty volume has been transferred to the 918 background fsck. A rebuild of fsck(8) utility is recommended 919 if you have updated the kernel. 920 921 To get the old behavior (recompute file system summary at mount 922 time), you can set vfs.ffs.compute_summary_at_mount=1 before 923 mounting the new volume. 924 92520050206: 926 The cpufreq import is complete. As part of this, the sysctls for 927 acpi(4) throttling have been removed. The power_profile script 928 has been updated, so you can use performance/economy_cpu_freq in 929 rc.conf(5) to set AC on/offline cpu frequencies. 930 93120050206: 932 NG_VERSION has been increased. Recompiling kernel (or ng_socket.ko) 933 requires recompiling libnetgraph and userland netgraph utilities. 934 93520050114: 936 Support for abbreviated forms of a number of ipfw options is 937 now deprecated. Warnings are printed to stderr indicating the 938 correct full form when a match occurs. Some abbreviations may 939 be supported at a later date based on user feedback. To be 940 considered for support, abbreviations must be in use prior to 941 this commit and unlikely to be confused with current key words. 942 94320041221: 944 By a popular demand, a lot of NOFOO options were renamed 945 to NO_FOO (see bsd.compat.mk for a full list). The old 946 spellings are still supported, but will cause annoying 947 warnings on stderr. Make sure you upgrade properly (see 948 the COMMON ITEMS: section later in this file). 949 95020041219: 951 Auto-loading of ancillary wlan modules such as wlan_wep has 952 been temporarily disabled; you need to statically configure 953 the modules you need into your kernel or explicitly load them 954 prior to use. Specifically, if you intend to use WEP encryption 955 with an 802.11 device load/configure wlan_wep; if you want to 956 use WPA with the ath driver load/configure wlan_tkip, wlan_ccmp, 957 and wlan_xauth as required. 958 95920041213: 960 The behaviour of ppp(8) has changed slightly. If lqr is enabled 961 (``enable lqr''), older versions would revert to LCP ECHO mode on 962 negotiation failure. Now, ``enable echo'' is required for this 963 behaviour. The ppp version number has been bumped to 3.4.2 to 964 reflect the change. 965 96620041201: 967 The wlan support has been updated to split the crypto support 968 into separate modules. For static WEP you must configure the 969 wlan_wep module in your system or build and install the module 970 in place where it can be loaded (the kernel will auto-load 971 the module when a wep key is configured). 972 97320041201: 974 The ath driver has been updated to split the tx rate control 975 algorithm into a separate module. You need to include either 976 ath_rate_onoe or ath_rate_amrr when configuring the kernel. 977 97820041116: 979 Support for systems with an 80386 CPU has been removed. Please 980 use FreeBSD 5.x or earlier on systems with an 80386. 981 98220041110: 983 We have had a hack which would mount the root filesystem 984 R/W if the device were named 'md*'. As part of the vnode 985 work I'm doing I have had to remove this hack. People 986 building systems which use preloaded MD root filesystems 987 may need to insert a "/sbin/mount -u -o rw /dev/md0 /" in 988 their /etc/rc scripts. 989 99020041104: 991 FreeBSD 5.3 shipped here. 992 99320041102: 994 The size of struct tcpcb has changed again due to the removal 995 of RFC1644 T/TCP. You have to recompile userland programs that 996 read kmem for tcp sockets directly (netstat, sockstat, etc.) 997 99820041022: 999 The size of struct tcpcb has changed. You have to recompile 1000 userland programs that read kmem for tcp sockets directly 1001 (netstat, sockstat, etc.) 1002 100320041016: 1004 RELENG_5 branched here. For older entries, please see updating 1005 in the RELENG_5 branch. 1006 1007COMMON ITEMS: 1008 1009 General Notes 1010 ------------- 1011 Avoid using make -j when upgrading. From time to time in the 1012 past there have been problems using -j with buildworld and/or 1013 installworld. This is especially true when upgrading between 1014 "distant" versions (eg one that cross a major release boundary 1015 or several minor releases, or when several months have passed 1016 on the -current branch). 1017 1018 Sometimes, obscure build problems are the result of environment 1019 poisoning. This can happen because the make utility reads its 1020 environment when searching for values for global variables. 1021 To run your build attempts in an "environmental clean room", 1022 prefix all make commands with 'env -i '. See the env(1) manual 1023 page for more details. 1024 1025 When upgrading from one major version to another it is generally 1026 best to upgrade to the latest code in the currently installed branch 1027 first, then do an upgrade to the new branch. This is the best-tested 1028 upgrade path, and has the highest probability of being successful. 1029 Please try this approach before reporting problems with a major 1030 version upgrade. 1031 1032 To build a kernel 1033 ----------------- 1034 If you are updating from a prior version of FreeBSD (even one just 1035 a few days old), you should follow this procedure. It is the most 1036 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1037 1038 make kernel-toolchain 1039 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1040 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1041 1042 To test a kernel once 1043 --------------------- 1044 If you just want to boot a kernel once (because you are not sure 1045 if it works, or if you want to boot a known bad kernel to provide 1046 debugging information) run 1047 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1048 nextboot -k testkernel 1049 1050 To just build a kernel when you know that it won't mess you up 1051 -------------------------------------------------------------- 1052 This assumes you are already running a 5.X system. Replace 1053 ${arch} with the architecture of your machine (e.g. "i386", 1054 "alpha", "amd64", "ia64", "pc98", "sparc64", etc). 1055 1056 cd src/sys/${arch}/conf 1057 config KERNEL_NAME_HERE 1058 cd ../compile/KERNEL_NAME_HERE 1059 make depend 1060 make 1061 make install 1062 1063 If this fails, go to the "To build a kernel" section. 1064 1065 To rebuild everything and install it on the current system. 1066 ----------------------------------------------------------- 1067 # Note: sometimes if you are running current you gotta do more than 1068 # is listed here if you are upgrading from a really old current. 1069 1070 <make sure you have good level 0 dumps> 1071 make buildworld 1072 make kernel KERNCONF=YOUR_KERNEL_HERE 1073 [1] 1074 <reboot in single user> [3] 1075 mergemaster -p [5] 1076 make installworld 1077 make delete-old 1078 mergemaster [4] 1079 <reboot> 1080 1081 1082 To cross-install current onto a separate partition 1083 -------------------------------------------------- 1084 # In this approach we use a separate partition to hold 1085 # current's root, 'usr', and 'var' directories. A partition 1086 # holding "/", "/usr" and "/var" should be about 2GB in 1087 # size. 1088 1089 <make sure you have good level 0 dumps> 1090 <boot into -stable> 1091 make buildworld 1092 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1093 <maybe newfs current's root partition> 1094 <mount current's root partition on directory ${CURRENT_ROOT}> 1095 make installworld DESTDIR=${CURRENT_ROOT} 1096 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1097 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1098 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1099 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1100 <reboot into current> 1101 <do a "native" rebuild/install as described in the previous section> 1102 <maybe install compatibility libraries from ports/misc/compat*> 1103 <reboot> 1104 1105 1106 To upgrade in-place from 5.x-stable to current 1107 ---------------------------------------------- 1108 <make sure you have good level 0 dumps> 1109 make buildworld [9] 1110 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1111 [1] 1112 <reboot in single user> [3] 1113 mergemaster -p [5] 1114 make installworld 1115 make delete-old 1116 mergemaster -i [4] 1117 <reboot> 1118 1119 Make sure that you've read the UPDATING file to understand the 1120 tweaks to various things you need. At this point in the life 1121 cycle of current, things change often and you are on your own 1122 to cope. The defaults can also change, so please read ALL of 1123 the UPDATING entries. 1124 1125 Also, if you are tracking -current, you must be subscribed to 1126 freebsd-current@freebsd.org. Make sure that before you update 1127 your sources that you have read and understood all the recent 1128 messages there. If in doubt, please track -stable which has 1129 much fewer pitfalls. 1130 1131 [1] If you have third party modules, such as vmware, you 1132 should disable them at this point so they don't crash your 1133 system on reboot. 1134 1135 [3] From the bootblocks, boot -s, and then do 1136 fsck -p 1137 mount -u / 1138 mount -a 1139 cd src 1140 adjkerntz -i # if CMOS is wall time 1141 Also, when doing a major release upgrade, it is required that 1142 you boot into single user mode to do the installworld. 1143 1144 [4] Note: This step is non-optional. Failure to do this step 1145 can result in a significant reduction in the functionality of the 1146 system. Attempting to do it by hand is not recommended and those 1147 that pursue this avenue should read this file carefully, as well 1148 as the archives of freebsd-current and freebsd-hackers mailing lists 1149 for potential gotchas. 1150 1151 [5] Usually this step is a noop. However, from time to time 1152 you may need to do this if you get unknown user in the following 1153 step. It never hurts to do it all the time. You may need to 1154 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1155 install) after the buildworld before this step if you last updated 1156 from current before 20020224 or from -stable before 20020408. 1157 1158 [8] In order to have a kernel that can run the 4.x binaries 1159 needed to do an installworld, you must include the COMPAT_FREEBSD4 1160 option in your kernel. Failure to do so may leave you with a system 1161 that is hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 1162 is required to run the 5.x binaries on more recent kernels. 1163 1164 Make sure that you merge any new devices from GENERIC since the 1165 last time you updated your kernel config file. 1166 1167 [9] When checking out sources, you must include the -P flag to have 1168 cvs prune empty directories. 1169 1170 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1171 "?=" instead of the "=" assignment operator, so that buildworld can 1172 override the CPUTYPE if it needs to. 1173 1174 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1175 not on the command line, or in /etc/make.conf. buildworld will 1176 warn if it is improperly defined. 1177FORMAT: 1178 1179This file contains a list, in reverse chronological order, of major 1180breakages in tracking -current. Not all things will be listed here, 1181and it only starts on October 16, 2004. Updating files can found in 1182previous releases if your system is older than this. 1183 1184Copyright information: 1185 1186Copyright 1998-2005 M. Warner Losh.
