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. 23 2420071118: 25 The AT keyboard emulation of sunkbd(4) has been turned on 26 by default. In order to make the special symbols of the Sun 27 keyboards driven by sunkbd(4) work under X these now have 28 to be configured the same way as Sun USB keyboards driven 29 by ukbd(4) (which also does AT keyboard emulation), f.e.: 30 31 Option "XkbLayout" "us" 32 Option "XkbRules" "xorg" 33 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 34 3520071024: 36 It has been decided that it is desirable to provide ABI 37 backwards compatibility to the FreeBSD 4/5/6 versions of the 38 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 39 broken with the introduction of PCI domain support (see the 40 20070930 entry). Unfortunately, this required the ABI of 41 PCIOCGETCONF to be broken again in order to be able to 42 provide backwards compatibility to the old version of that 43 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 44 again. As for prominent ports this affects neither pciutils 45 nor xorg-server this time, the hal port needs to be rebuilt 46 however. 47 4820071020: 49 The misnamed kthread_create() and friends have been renamed 50 to kproc_create() etc. Many of the callers already 51 used kproc_start().. 52 I will return kthread_create() and friends in a while 53 with implementations that actually create threads, not procs. 54 Renaming corresponds with version 800002. 55 5620071010: 57 RELENG_7 branched. 58 5920071009: 60 Setting WITHOUT_LIBPTHREAD now means WITHOUT_LIBKSE and 61 WITHOUT_LIBTHR are set. 62 6320070930: 64 The PCI code has been made aware of PCI domains. This means that 65 the location strings as used by pciconf(8) etc are now in the 66 following format: pci<domain>:<bus>:<device>[:<function>]. It 67 also means that consumers of <sys/pciio.h> potentially need to 68 be recompiled; this includes the hal and xorg-server ports. 69 7020070928: 71 The caching daemon (cached) was renamed to nscd. nscd.conf 72 configuration file should be used instead of cached.conf and 73 nscd_enable, nscd_pidfile and nscd_flags options should be used 74 instead of cached_enable, cached_pidfile and cached_flags in 75 rc.conf. 76 7720070921: 78 The getfacl(1) utility now prints owning user and group name 79 instead of owning uid and gid in the three line comment header. 80 This is the same behavior as getfacl(1) on Solaris and Linux. 81 8220070704: 83 The new IPsec code is now compiled in using the IPSEC option. The 84 IPSEC option now requires "device crypto" be defined in your kernel 85 configuration. The FAST_IPSEC kernel option is now deprecated. 86 8720070702: 88 The packet filter (pf) code has been updated to OpenBSD 4.1 Please 89 note the changed syntax - keep state is now on by default. Also 90 note the fact that ftp-proxy(8) has been changed from bottom up and 91 has been moved from libexec to usr/sbin. Changes in the ALTQ 92 handling also affect users of IPFW's ALTQ capabilities. 93 9420070701: 95 Remove KAME IPsec in favor of FAST_IPSEC, which is now the 96 only IPsec supported by FreeBSD. The new IPsec stack 97 supports both IPv4 and IPv6. The kernel option will change 98 after the code changes have settled in. For now the kernel 99 option IPSEC is deprecated and FAST_IPSEC is the only option, that 100 will change after some settling time. 101 10220070701: 103 The wicontrol(8) utility has been removed from the base system. wi(4) 104 cards should be configured using ifconfig(8), see the man page for more 105 information. 106 10720070612: 108 The i386/amd64 GENERIC kernel now defaults to the nfe(4) driver 109 instead of the nve(4) driver. Please update your configuration 110 accordingly. 111 11220070612: 113 By default, /etc/rc.d/sendmail no longer rebuilds the aliases 114 database if it is missing or older than the aliases file. If 115 desired, set the new rc.conf option sendmail_rebuild_aliases 116 to "YES" to restore that functionality. 117 11820070612: 119 The IPv4 multicast socket code has been considerably modified, and 120 moved to the file sys/netinet/in_mcast.c. Initial support for the 121 RFC 3678 Source-Specific Multicast Socket API has been added to 122 the IPv4 network stack. 123 124 Strict multicast and broadcast reception is now the default for 125 UDP/IPv4 sockets; the net.inet.udp.strict_mcast_mship sysctl variable 126 has now been removed. 127 128 The RFC 1724 hack for interface selection has been removed; the use 129 of the Linux-derived ip_mreqn structure with IP_MULTICAST_IF has 130 been added to replace it. Consumers such as routed will soon be 131 updated to reflect this. 132 133 These changes affect users who are running routed(8) or rdisc(8) 134 from the FreeBSD base system on point-to-point or unnumbered 135 interfaces. 136 13720070610: 138 The net80211 layer has changed significantly and all wireless 139 drivers that depend on it need to be recompiled. Further these 140 changes require that any program that interacts with the wireless 141 support in the kernel be recompiled; this includes: ifconfig, 142 wpa_supplicant, hostapd, and wlanstats. Users must also, for 143 the moment, kldload the wlan_scan_sta and/or wlan_scan_ap modules 144 if they use modules for wireless support. These modules implement 145 scanning support for station and ap modes, respectively. Failure 146 to load the appropriate module before marking a wireless interface 147 up will result in a message to the console and the device not 148 operating properly. 149 15020070610: 151 The pam_nologin(8) module ceases to provide an authentication 152 function and starts providing an account management function. 153 Consequent changes to /etc/pam.d should be brought in using 154 mergemaster(8). Third-party files in /usr/local/etc/pam.d may 155 need manual editing as follows. Locate this line (or similar): 156 157 auth required pam_nologin.so no_warn 158 159 and change it according to this example: 160 161 account required pam_nologin.so no_warn 162 163 That is, the first word needs to be changed from "auth" to 164 "account". The new line can be moved to the account section 165 within the file for clarity. Not updating pam.conf(5) files 166 will result in nologin(5) ignored by the respective services. 167 16820070529: 169 The ether_ioctl() function has been synchronized with ioctl(2) 170 and ifnet.if_ioctl. Due to that, the size of one of its arguments 171 has changed on 64-bit architectures. All kernel modules using 172 ether_ioctl() need to be rebuilt on such architectures. 173 17420070516: 175 Improved INCLUDE_CONFIG_FILE support has been introduced to the 176 config(8) utility. In order to take advantage of this new 177 functionality, you are expected to recompile and install 178 src/usr.sbin/config. If you don't rebuild config(8), and your 179 kernel configuration depends on INCLUDE_CONFIG_FILE, the kernel 180 build will be broken because of a missing "kernconfstring" 181 symbol. 182 18320070513: 184 Symbol versioning is enabled by default. To disable it, use 185 option WITHOUT_SYMVER. It is not advisable to attempt to 186 disable symbol versioning once it is enabled; your installworld 187 will break because a symbol version-less libc will get installed 188 before the install tools. As a result, the old install tools, 189 which previously had symbol dependencies to FBSD_1.0, will fail 190 because the freshly installed libc will not have them. 191 192 The default threading library (providing "libpthread") has been 193 changed to libthr. If you wish to have libkse as your default, 194 use option DEFAULT_THREAD_LIB=libkse for the buildworld. 195 19620070423: 197 The ABI breakage in sendmail(8)'s libmilter has been repaired 198 so it is no longer necessary to recompile mail filters (aka, 199 milters). If you recompiled mail filters after the 20070408 200 note, it is not necessary to recompile them again. 201 20220070417: 203 The new trunk(4) driver has been renamed to lagg(4) as it better 204 reflects its purpose. ifconfig will need to be recompiled. 205 20620070408: 207 sendmail(8) has been updated to version 8.14.1. Mail filters 208 (aka, milters) compiled against the libmilter included in the 209 base operating system should be recompiled. 210 21120070302: 212 Firmwares for ipw(4) and iwi(4) are now included in the base tree. 213 In order to use them one must agree to the respective LICENSE in 214 share/doc/legal and define legal.intel_<name>.license_ack=1 via 215 loader.conf(5) or kenv(1). Make sure to deinstall the now 216 deprecated modules from the respective firmware ports. 217 21820070228: 219 The name resolution/mapping functions addr2ascii(3) and ascii2addr(3) 220 were removed from FreeBSD's libc. These originally came from INRIA 221 IPv6. Nothing in FreeBSD ever used them. They may be regarded as 222 deprecated in previous releases. 223 The AF_LINK support for getnameinfo(3) was merged from NetBSD to 224 replace it as a more portable (and re-entrant) API. 225 22620070224: 227 To support interrupt filtering a modification to the newbus API 228 has occurred, ABI was broken and __FreeBSD_version was bumped 229 to 700031. Please make sure that your kernel and modules are in 230 sync. For more info: 231 http://docs.freebsd.org/cgi/mid.cgi?20070221233124.GA13941 232 23320070224: 234 The IPv6 multicast forwarding code may now be loaded into GENERIC 235 kernels by loading the ip_mroute.ko module. This is built into the 236 module unless WITHOUT_INET6 or WITHOUT_INET6_SUPPORT options are 237 set; see src.conf(5) for more information. 238 23920070214: 240 The output of netstat -r has changed. Without -n, we now only 241 print a "network name" without the prefix length if the network 242 address and mask exactly match a Class A/B/C network, and an entry 243 exists in the nsswitch "networks" map. 244 With -n, we print the full unabbreviated CIDR network prefix in 245 the form "a.b.c.d/p". 0.0.0.0/0 is always printed as "default". 246 This change is in preparation for changes such as equal-cost 247 multipath, and to more generally assist operational deployment 248 of FreeBSD as a modern IPv4 router. 249 25020070210: 251 PIM has been turned on by default in the IPv4 multicast 252 routing code. The kernel option 'PIM' has now been removed. 253 PIM is now built by default if option 'MROUTING' is specified. 254 It may now be loaded into GENERIC kernels by loading the 255 ip_mroute.ko module. 256 25720070207: 258 Support for IPIP tunnels (VIFF_TUNNEL) in IPv4 multicast routing 259 has been removed. Its functionality may be achieved by explicitly 260 configuring gif(4) interfaces and using the 'phyint' keyword in 261 mrouted.conf. 262 XORP does not support source-routed IPv4 multicast tunnels nor the 263 integrated IPIP tunneling, therefore it is not affected by this 264 change. The __FreeBSD_version macro has been bumped to 700030. 265 26620061221: 267 Support for PCI Message Signalled Interrupts has been 268 re-enabled in the bge driver, only for those chips which are 269 believed to support it properly. If there are any problems, 270 MSI can be disabled completely by setting the 271 'hw.pci.enable_msi' and 'hw.pci.enable_msix' tunables to 0 272 in the loader. 273 27420061214: 275 Support for PCI Message Signalled Interrupts has been 276 disabled again in the bge driver. Many revisions of the 277 hardware fail to support it properly. Support can be 278 re-enabled by removing the #define of BGE_DISABLE_MSI in 279 "src/sys/dev/bge/if_bge.c". 280 28120061214: 282 Support for PCI Message Signalled Interrupts has been added 283 to the bge driver. If there are any problems, MSI can be 284 disabled completely by setting the 'hw.pci.enable_msi' and 285 'hw.pci.enable_msix' tunables to 0 in the loader. 286 28720061205: 288 The removal of several facets of the experimental Threading 289 system from the kernel means that the proc and thread structures 290 have changed quite a bit. I suggest all kernel modules that might 291 reference these structures be recompiled.. Especially the 292 linux module. 293 29420061126: 295 Sound infrastructure has been updated with various fixes and 296 improvements. Most of the changes are pretty much transparent, 297 with exceptions of followings: 298 1) All sound driver specific sysctls (hw.snd.pcm%d.*) have been 299 moved to their own dev sysctl nodes, for example: 300 hw.snd.pcm0.vchans -> dev.pcm.0.vchans 301 2) /dev/dspr%d.%d has been deprecated. Each channel now has its 302 own chardev in the form of "dsp%d.<function>%d", where <function> 303 is p = playback, r = record and v = virtual, respectively. Users 304 are encouraged to use these devs instead of (old) "/dev/dsp%d.%d". 305 This does not affect those who are using "/dev/dsp". 306 30720061122: 308 The following binaries have been disconnected from the build: 309 mount_devfs, mount_ext2fs, mount_fdescfs, mount_procfs, mount_linprocfs, 310 and mount_std. The functionality of these programs has been 311 moved into the mount program. For example, to mount a devfs 312 filesystem, instead of using mount_devfs, use: "mount -t devfs". 313 This does not affect entries in /etc/fstab, since entries in 314 /etc/fstab are always processed with "mount -t fstype". 315 31620061113: 317 Support for PCI Message Signalled Interrupts on i386 and amd64 318 has been added to the kernel and various drivers will soon be 319 updated to use MSI when it is available. If there are any problems, 320 MSI can be disabled completely by setting the 'hw.pci.enable_msi' 321 and 'hw.pci.enable_msix' tunables to 0 in the loader. 322 32320061110: 324 The MUTEX_PROFILING option has been renamed to LOCK_PROFILING. 325 The lockmgr object layout has been changed as a result of having 326 a lock_object embedded in it. As a consequence all file system 327 kernel modules must be re-compiled. The mutex profiling man page 328 has not yet been updated to reflect this change. 329 33020061026: 331 KSE in the kernel has now been made optional and turned on by 332 default. Use 'nooption KSE' in your kernel config to turn it 333 off. All kernel modules *must* be recompiled after this change. 334 There-after, modules from a KSE kernel should be compatible with 335 modules from a NOKSE kernel due to the temporary padding fields 336 added to 'struct proc'. 337 33820060929: 339 mrouted and its utilities have been removed from the base system. 340 34120060927: 342 Some ioctl(2) command codes have changed. Full backward ABI 343 compatibility is provided if the "options COMPAT_FREEBSD6" is 344 present in the kernel configuration file. Make sure to add 345 this option to your kernel config file, or recompile X.Org 346 and the rest of ports; otherwise they may refuse to work. 347 34820060924: 349 tcpslice has been removed from the base system. 350 35120060913: 352 The sizes of struct tcpcb (and struct xtcpcb) have changed due to 353 the rewrite of TCP syncookies. Tools like netstat, sockstat, and 354 systat needs to be rebuilt. 355 35620060903: 357 libpcap updated to v0.9.4 and tcpdump to v3.9.4 358 35920060816: 360 The IPFIREWALL_FORWARD_EXTENDED option is gone and the behaviour 361 for IPFIREWALL_FORWARD is now as it was before when it was first 362 committed and for years after. The behaviour is now ON. 363 36420060725: 365 enigma(1)/crypt(1) utility has been changed on 64 bit architectures. 366 Now it can decrypt files created from different architectures. 367 Unfortunately, it is no longer able to decrypt a cipher text 368 generated with an older version on 64 bit architectures. 369 If you have such a file, you need old utility to decrypt it. 370 37120060709: 372 The interface version of the i4b kernel part has changed. So 373 after updating the kernel sources and compiling a new kernel, 374 the i4b user space tools in "/usr/src/usr.sbin/i4b" must also 375 be rebuilt, and vice versa. 376 37720060627: 378 The XBOX kernel now defaults to the nfe(4) driver instead of 379 the nve(4) driver. Please update your configuration 380 accordingly. 381 38220060514: 383 The i386-only lnc(4) driver for the AMD Am7900 LANCE and Am79C9xx 384 PCnet family of NICs has been removed. The new le(4) driver serves 385 as an equivalent but cross-platform replacement with the pcn(4) 386 driver still providing performance-optimized support for the subset 387 of AMD Am79C971 PCnet-FAST and greater chips as before. 388 38920060511: 390 The machdep.* sysctls and the adjkerntz utility have been 391 modified a bit. The new adjkerntz utility uses the new 392 sysctl names and sysctlbyname() calls, so it may be impossible 393 to run an old /sbin/adjkerntz utility in single-user mode 394 with a new kernel. Replace the `adjkerntz -i' step before 395 `make installworld' with: 396 397 /usr/obj/usr/src/sbin/adjkerntz/adjkerntz -i 398 399 and proceed as usual with the rest of the installworld-stage 400 steps. Otherwise, you risk installing binaries with their 401 timestamp set several hours in the future, especially if 402 you are running with local time set to GMT+X hours. 403 40420060412: 405 The ip6fw utility has been removed. The behavior provided by 406 ip6fw has been in ipfw2 for a good while and the rc.d scripts 407 have been updated to deal with it. There are some rules that 408 might not migrate cleanly. Use rc.firewall6 as a template to 409 rewrite rules. 410 41120060428: 412 The puc(4) driver has been overhauled. The ebus(4) and sbus(4) 413 attachments have been removed. Make sure to configure scc(4) 414 on sparc64. Note also that by default puc(4) will use uart(4) 415 and not sio(4) for serial ports because interrupt handling has 416 been optimized for multi-port serial cards and only uart(4) 417 implements the interface to support it. 418 41920060330: 420 The scc(4) driver replaces puc(4) for Serial Communications 421 Controllers (SCCs) like the Siemens SAB82532 and the Zilog 422 Z8530. On sparc64, it is advised to add scc(4) to the kernel 423 configuration to make sure that the serial ports remain 424 functional. 425 42620060317: 427 Most world/kernel related NO_* build options changed names. 428 New knobs have common prefixes WITHOUT_*/WITH_* (modelled 429 after FreeBSD ports) and should be set in /etc/src.conf 430 (the src.conf(5) manpage is provided). Full backwards 431 compatibility is maintained for the time being though it's 432 highly recommended to start moving old options out of the 433 system-wide /etc/make.conf file into the new /etc/src.conf 434 while also properly renaming them. More conversions will 435 likely follow. Posting to current@: 436 437 http://lists.freebsd.org/pipermail/freebsd-current/2006-March/061725.html 438 43920060305: 440 The NETSMBCRYPTO kernel option has been retired because its 441 functionality is always included in NETSMB and smbfs.ko now. 442 44320060303: 444 The TDFX_LINUX kernel option was retired and replaced by the 445 tdfx_linux device. The latter can be loaded as the 3dfx_linux.ko 446 kernel module. Loading it alone should suffice to get 3dfx support 447 for Linux apps because it will pull in 3dfx.ko and linux.ko through 448 its dependencies. 449 45020060204: 451 The 'audit' group was added to support the new auditing functionality 452 in the base system. Be sure to follow the directions for updating, 453 including the requirement to run mergemaster -p. 454 45520060201: 456 The kernel ABI to file system modules was changed on i386. 457 Please make sure that your kernel and modules are in sync. 458 45920060118: 460 This actually occured some time ago, but installing the kernel 461 now also installs a bunch of symbol files for the kernel modules. 462 This increases the size of /boot/kernel to about 67Mbytes. You 463 will need twice this if you will eventually back this up to kernel.old 464 on your next install. 465 If you have a shortage of room in your root partition, you should add 466 -DINSTALL_NODEBUG to your make arguments or add INSTALL_NODEBUG="yes" 467 to your /etc/make.conf. 468 46920060113: 470 libc's malloc implementation has been replaced. This change has the 471 potential to uncover application bugs that previously went unnoticed. 472 See the malloc(3) manual page for more details. 473 47420060112: 475 The generic netgraph(4) cookie has been changed. If you upgrade 476 kernel passing this point, you also need to upgrade userland 477 and netgraph(4) utilities like ports/net/mpd or ports/net/mpd4. 478 47920060106: 480 si(4)'s device files now contain the unit number. 481 Uses of {cua,tty}A[0-9a-f] should be replaced by {cua,tty}A0[0-9a-f]. 482 48320060106: 484 The kernel ABI was mostly destroyed due to a change in the size 485 of struct lock_object which is nested in other structures such 486 as mutexes which are nested in all sorts of other structures. 487 Make sure your kernel and modules are in sync. 488 48920051231: 490 The page coloring algorithm in the VM subsystem was converted 491 from tuning with kernel options to autotuning. Please remove 492 any PQ_* option except PQ_NOOPT from your kernel config. 493 49420051211: 495 The net80211-related tools in the tools/tools/ath directory 496 have been moved to tools/tools/net80211 and renamed with a 497 "wlan" prefix. Scripts that use them should be adjusted 498 accordingly. 499 50020051202: 501 Scripts in the local_startup directories (as defined in 502 /etc/defaults/rc.conf) that have the new rc.d semantics will 503 now be run as part of the base system rcorder. If there are 504 errors or problems with one of these local scripts, it could 505 cause boot problems. If you encounter such problems, boot in 506 single user mode, remove that script from the */rc.d directory. 507 Please report the problem to the port's maintainer, and the 508 freebsd-ports@freebsd.org mailing list. 509 51020051129: 511 The nodev mount option was deprecated in RELENG_6 (where it 512 was a no-op), and is now unsupported. If you have nodev or dev listed 513 in /etc/fstab, remove it, otherwise it will result in a mount error. 514 51520051129: 516 ABI between ipfw(4) and ipfw(8) has been changed. You need 517 to rebuild ipfw(8) when rebuilding kernel. 518 51920051108: 520 rp(4)'s device files now contain the unit number. 521 Uses of {cua,tty}R[0-9a-f] should be replaced by {cua,tty}R0[0-9a-f]. 522 52320051029: 524 /etc/rc.d/ppp-user has been renamed to /etc/rc.d/ppp. 525 Its /etc/rc.conf.d configuration file has been `ppp' from 526 the beginning, and hence there is no need to touch it. 527 52820051014: 529 Now most modules get their build-time options from the kernel 530 configuration file. A few modules still have fixed options 531 due to their non-conformant implementation, but they will be 532 corrected eventually. You may need to review the options of 533 the modules in use, explicitly specify the non-default options 534 in the kernel configuration file, and rebuild the kernel and 535 modules afterwards. 536 53720051001: 538 kern.polling.enable sysctl MIB is now deprecated. Use ifconfig(8) 539 to turn polling(4) on your interfaces. 540 54120050927: 542 The old bridge(4) implementation was retired. The new 543 if_bridge(4) serves as a full functional replacement. 544 54520050722: 546 The ai_addrlen of a struct addrinfo was changed to a socklen_t 547 to conform to POSIX-2001. This change broke an ABI 548 compatibility on 64 bit architecture. You have to recompile 549 userland programs that use getaddrinfo(3) on 64 bit 550 architecture. 551 55220050711: 553 RELENG_6 branched here. 554 55520050629: 556 The pccard_ifconfig rc.conf variable has been removed and a new 557 variable, ifconfig_DEFAULT has been introduced. Unlike 558 pccard_ifconfig, ifconfig_DEFAULT applies to ALL interfaces that 559 do not have ifconfig_ifn entries rather than just those in 560 removable_interfaces. 561 56220050616: 563 Some previous versions of PAM have permitted the use of 564 non-absolute paths in /etc/pam.conf or /etc/pam.d/* when referring 565 to third party PAM modules in /usr/local/lib. A change has been 566 made to require the use of absolute paths in order to avoid 567 ambiguity and dependence on library path configuration, which may 568 affect existing configurations. 569 57020050610: 571 Major changes to network interface API. All drivers must be 572 recompiled. Drivers not in the base system will need to be 573 updated to the new APIs. 574 57520050609: 576 Changes were made to kinfo_proc in sys/user.h. Please recompile 577 userland, or commands like `fstat', `pkill', `ps', `top' and `w' 578 will not behave correctly. 579 580 The API and ABI for hwpmc(4) have changed with the addition 581 of sampling support. Please recompile lib/libpmc(3) and 582 usr.sbin/{pmcstat,pmccontrol}. 583 58420050606: 585 The OpenBSD dhclient was imported in place of the ISC dhclient 586 and the network interface configuration scripts were updated 587 accordingly. If you use DHCP to configure your interfaces, you 588 must now run devd. Also, DNS updating was lost so you will need 589 to find a workaround if you use this feature. 590 591 The '_dhcp' user was added to support the OpenBSD dhclient. Be 592 sure to run mergemaster -p (like you are supposed to do every time 593 anyway). 594 59520050605: 596 if_bridge was added to the tree. This has changed struct ifnet. 597 Please recompile userland and all network related modules. 598 59920050603: 600 The n_net of a struct netent was changed to an uint32_t, and 601 1st argument of getnetbyaddr() was changed to an uint32_t, to 602 conform to POSIX-2001. These changes broke an ABI 603 compatibility on 64 bit architecture. With these changes, 604 shlib major of libpcap was bumped. You have to recompile 605 userland programs that use getnetbyaddr(3), getnetbyname(3), 606 getnetent(3) and/or libpcap on 64 bit architecture. 607 60820050528: 609 Kernel parsing of extra options on '#!' first lines of shell 610 scripts has changed. Lines with multiple options likely will 611 fail after this date. For full details, please see 612 http://people.freebsd.org/~gad/Updating-20050528.txt 613 61420050503: 615 The packet filter (pf) code has been updated to OpenBSD 3.7 616 Please note the changed anchor syntax and the fact that 617 authpf(8) now needs a mounted fdescfs(5) to function. 618 61920050415: 620 The NO_MIXED_MODE kernel option has been removed from the i386 621 amd64 platforms as its use has been superceded by the new local 622 APIC timer code. Any kernel config files containing this option 623 should be updated. 624 62520050227: 626 The on-disk format of LC_CTYPE files was changed to be machine 627 independent. Please make sure NOT to use NO_CLEAN buildworld 628 when crossing this point. Crossing this point also requires 629 recompile or reinstall of all locale depended packages. 630 63120050225: 632 The ifi_epoch member of struct if_data has been changed to 633 contain the uptime at which the interface was created or the 634 statistics zeroed rather then the wall clock time because 635 wallclock time may go backwards. This should have no impact 636 unless an snmp implementation is using this value (I know of 637 none at this point.) 638 63920050224: 640 The acpi_perf and acpi_throttle drivers are now part of the 641 acpi(4) main module. They are no longer built separately. 642 64320050223: 644 The layout of struct image_params has changed. You have to 645 recompile all compatibility modules (linux, svr4, etc) for use 646 with the new kernel. 647 64820050223: 649 The p4tcc driver has been merged into cpufreq(4). This makes 650 "options CPU_ENABLE_TCC" obsolete. Please load cpufreq.ko or 651 compile in "device cpufreq" to restore this functionality. 652 65320050220: 654 The responsibility of recomputing the file system summary of 655 a SoftUpdates-enabled dirty volume has been transferred to the 656 background fsck. A rebuild of fsck(8) utility is recommended 657 if you have updated the kernel. 658 659 To get the old behavior (recompute file system summary at mount 660 time), you can set vfs.ffs.compute_summary_at_mount=1 before 661 mounting the new volume. 662 66320050206: 664 The cpufreq import is complete. As part of this, the sysctls for 665 acpi(4) throttling have been removed. The power_profile script 666 has been updated, so you can use performance/economy_cpu_freq in 667 rc.conf(5) to set AC on/offline cpu frequencies. 668 66920050206: 670 NG_VERSION has been increased. Recompiling kernel (or ng_socket.ko) 671 requires recompiling libnetgraph and userland netgraph utilities. 672 67320050114: 674 Support for abbreviated forms of a number of ipfw options is 675 now deprecated. Warnings are printed to stderr indicating the 676 correct full form when a match occurs. Some abbreviations may 677 be supported at a later date based on user feedback. To be 678 considered for support, abbreviations must be in use prior to 679 this commit and unlikely to be confused with current key words. 680 68120041221: 682 By a popular demand, a lot of NOFOO options were renamed 683 to NO_FOO (see bsd.compat.mk for a full list). The old 684 spellings are still supported, but will cause annoying 685 warnings on stderr. Make sure you upgrade properly (see 686 the COMMON ITEMS: section later in this file). 687 68820041219: 689 Auto-loading of ancillary wlan modules such as wlan_wep has 690 been temporarily disabled; you need to statically configure 691 the modules you need into your kernel or explicitly load them 692 prior to use. Specifically, if you intend to use WEP encryption 693 with an 802.11 device load/configure wlan_wep; if you want to 694 use WPA with the ath driver load/configure wlan_tkip, wlan_ccmp, 695 and wlan_xauth as required. 696 69720041213: 698 The behaviour of ppp(8) has changed slightly. If lqr is enabled 699 (``enable lqr''), older versions would revert to LCP ECHO mode on 700 negotiation failure. Now, ``enable echo'' is required for this 701 behaviour. The ppp version number has been bumped to 3.4.2 to 702 reflect the change. 703 70420041201: 705 The wlan support has been updated to split the crypto support 706 into separate modules. For static WEP you must configure the 707 wlan_wep module in your system or build and install the module 708 in place where it can be loaded (the kernel will auto-load 709 the module when a wep key is configured). 710 71120041201: 712 The ath driver has been updated to split the tx rate control 713 algorithm into a separate module. You need to include either 714 ath_rate_onoe or ath_rate_amrr when configuring the kernel. 715 71620041116: 717 Support for systems with an 80386 CPU has been removed. Please 718 use FreeBSD 5.x or earlier on systems with an 80386. 719 72020041110: 721 We have had a hack which would mount the root filesystem 722 R/W if the device were named 'md*'. As part of the vnode 723 work I'm doing I have had to remove this hack. People 724 building systems which use preloaded MD root filesystems 725 may need to insert a "/sbin/mount -u -o rw /dev/md0 /" in 726 their /etc/rc scripts. 727 72820041104: 729 FreeBSD 5.3 shipped here. 730 73120041102: 732 The size of struct tcpcb has changed again due to the removal 733 of RFC1644 T/TCP. You have to recompile userland programs that 734 read kmem for tcp sockets directly (netstat, sockstat, etc.) 735 73620041022: 737 The size of struct tcpcb has changed. You have to recompile 738 userland programs that read kmem for tcp sockets directly 739 (netstat, sockstat, etc.) 740 74120041016: 742 RELENG_5 branched here. For older entries, please see updating 743 in the RELENG_5 branch. 744 745COMMON ITEMS: 746 747 General Notes 748 ------------- 749 Avoid using make -j when upgrading. From time to time in the 750 past there have been problems using -j with buildworld and/or 751 installworld. This is especially true when upgrading between 752 "distant" versions (eg one that cross a major release boundary 753 or several minor releases, or when several months have passed 754 on the -current branch). 755 756 Sometimes, obscure build problems are the result of environment 757 poisoning. This can happen because the make utility reads its 758 environment when searching for values for global variables. 759 To run your build attempts in an "environmental clean room", 760 prefix all make commands with 'env -i '. See the env(1) manual 761 page for more details. 762 763 When upgrading from one major version to another it is generally 764 best to upgrade to the latest code in the currently installed branch 765 first, then do an upgrade to the new branch. This is the best-tested 766 upgrade path, and has the highest probability of being successful. 767 Please try this approach before reporting problems with a major 768 version upgrade. 769 770 To build a kernel 771 ----------------- 772 If you are updating from a prior version of FreeBSD (even one just 773 a few days old), you should follow this procedure. It is the most 774 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 775 776 make kernel-toolchain 777 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 778 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 779 780 To test a kernel once 781 --------------------- 782 If you just want to boot a kernel once (because you are not sure 783 if it works, or if you want to boot a known bad kernel to provide 784 debugging information) run 785 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 786 nextboot -k testkernel 787 788 To just build a kernel when you know that it won't mess you up 789 -------------------------------------------------------------- 790 This assumes you are already running a 5.X system. Replace 791 ${arch} with the architecture of your machine (e.g. "i386", 792 "alpha", "amd64", "ia64", "pc98", "sparc64", etc). 793 794 cd src/sys/${arch}/conf 795 config KERNEL_NAME_HERE 796 cd ../compile/KERNEL_NAME_HERE 797 make depend 798 make 799 make install 800 801 If this fails, go to the "To build a kernel" section. 802 803 To rebuild everything and install it on the current system. 804 ----------------------------------------------------------- 805 # Note: sometimes if you are running current you gotta do more than 806 # is listed here if you are upgrading from a really old current. 807 808 <make sure you have good level 0 dumps> 809 make buildworld 810 make kernel KERNCONF=YOUR_KERNEL_HERE 811 [1] 812 <reboot in single user> [3] 813 mergemaster -p [5] 814 make installworld 815 make delete-old 816 mergemaster [4] 817 <reboot> 818 819 820 To cross-install current onto a separate partition 821 -------------------------------------------------- 822 # In this approach we use a separate partition to hold 823 # current's root, 'usr', and 'var' directories. A partition 824 # holding "/", "/usr" and "/var" should be about 2GB in 825 # size. 826 827 <make sure you have good level 0 dumps> 828 <boot into -stable> 829 make buildworld 830 make buildkernel KERNCONF=YOUR_KERNEL_HERE 831 <maybe newfs current's root partition> 832 <mount current's root partition on directory ${CURRENT_ROOT}> 833 make installworld DESTDIR=${CURRENT_ROOT} 834 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 835 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 836 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 837 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 838 <reboot into current> 839 <do a "native" rebuild/install as described in the previous section> 840 <maybe install compatibility libraries from src/lib/compat> 841 <reboot> 842 843 844 To upgrade in-place from 5.x-stable to current 845 ---------------------------------------------- 846 <make sure you have good level 0 dumps> 847 make buildworld [9] 848 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 849 [1] 850 <reboot in single user> [3] 851 mergemaster -p [5] 852 make installworld 853 make delete-old 854 mergemaster -i [4] 855 <reboot> 856 857 Make sure that you've read the UPDATING file to understand the 858 tweaks to various things you need. At this point in the life 859 cycle of current, things change often and you are on your own 860 to cope. The defaults can also change, so please read ALL of 861 the UPDATING entries. 862 863 Also, if you are tracking -current, you must be subscribed to 864 freebsd-current@freebsd.org. Make sure that before you update 865 your sources that you have read and understood all the recent 866 messages there. If in doubt, please track -stable which has 867 much fewer pitfalls. 868 869 [1] If you have third party modules, such as vmware, you 870 should disable them at this point so they don't crash your 871 system on reboot. 872 873 [3] From the bootblocks, boot -s, and then do 874 fsck -p 875 mount -u / 876 mount -a 877 cd src 878 adjkerntz -i # if CMOS is wall time 879 Also, when doing a major release upgrade, it is required that 880 you boot into single user mode to do the installworld. 881 882 [4] Note: This step is non-optional. Failure to do this step 883 can result in a significant reduction in the functionality of the 884 system. Attempting to do it by hand is not recommended and those 885 that pursue this avenue should read this file carefully, as well 886 as the archives of freebsd-current and freebsd-hackers mailing lists 887 for potential gotchas. 888 889 [5] Usually this step is a noop. However, from time to time 890 you may need to do this if you get unknown user in the following 891 step. It never hurts to do it all the time. You may need to 892 install a new mergemaster (cd src/usr.sbin/mergemaster && make 893 install) after the buildworld before this step if you last updated 894 from current before 20020224 or from -stable before 20020408. 895 896 [8] In order to have a kernel that can run the 4.x binaries 897 needed to do an installworld, you must include the COMPAT_FREEBSD4 898 option in your kernel. Failure to do so may leave you with a system 899 that is hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 900 is required to run the 5.x binaries on more recent kernels. 901 902 Make sure that you merge any new devices from GENERIC since the 903 last time you updated your kernel config file. 904 905 [9] When checking out sources, you must include the -P flag to have 906 cvs prune empty directories. 907 908 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 909 "?=" instead of the "=" assignment operator, so that buildworld can 910 override the CPUTYPE if it needs to. 911 912 MAKEOBJDIRPREFIX must be defined in an environment variable, and 913 not on the command line, or in /etc/make.conf. buildworld will 914 warn if it is improperly defined. 915FORMAT: 916 917This file contains a list, in reverse chronological order, of major 918breakages in tracking -current. Not all things will be listed here, 919and it only starts on October 16, 2004. Updating files can found in 920previous releases if your system is older than this. 921 922Copyright information: 923 924Copyright 1998-2005 M. Warner Losh.
