[SA-14:20] 251 252 Fix routed(8) remote denial of service vulnerability. [SA-14:21] 253 254 Fix memory leak in sandboxed namei lookup. [SA-14:22] 255 256 Fix OpenSSL multiple vulnerabilities. [SA-14:23] 257 25820140916: p2 FreeBSD-SA-14:19.tcp 259 Fix Denial of Service in TCP packet processing. [SA-14:19] 260 26120140909: p1 FreeBSD-SA-14:18.openssl 262 Fix OpenSSL multiple vulnerabilities. [SA-14:18] 263 26420140716: 265 9.3-RELEASE. 266 26720140608: 268 On i386 and amd64 systems, the onifconsole flag is now set by default 269 in /etc/ttys for ttyu0. This causes ttyu0 to be automatically enabled 270 as a login TTY if it is set in the bootloader as an active kernel 271 console. No changes in behavior should result otherwise. To revert to 272 the previous behavior, set ttyu0 to "off" in /etc/ttys. 273 27420140512: 275 Clang and llvm have been upgraded to 3.4.1 release. 276 27720140321: 278 Clang and llvm have been upgraded to 3.4 release. 279 28020140216: 281 The nve(4) driver for NVIDIA nForce MCP Ethernet adapters has 282 been deprecated and will not be part of FreeBSD 11.0 and later 283 releases. If you use this driver, please consider switching to 284 the nfe(4) driver instead. 285 28620131216: 287 The behavior of gss_pseudo_random() for the krb5 mechanism 288 has changed, for applications requesting a longer random string 289 than produced by the underlying enctype's pseudo-random() function. 290 In particular, the random string produced from a session key of 291 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 292 be different at the 17th octet and later, after this change. 293 The counter used in the PRF+ construction is now encoded as a 294 big-endian integer in accordance with RFC 4402. 295 __FreeBSD_version is bumped to 902505. 296 29720130930: 298 9.2-RELEASE. 299 30020130823: 301 Behavior of devfs rules path matching has been changed. 302 Pattern is now always matched against fully qualified devfs 303 path and slash characters must be explicitly matched by 304 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 305 subdirectories must be reviewed. 306 30720130705: 308 hastctl(8)'s `status' command output changed to terse one-liner format. 309 Scripts using this should switch to `list' command or be rewritten. 310 31120130618: 312 Fix a bug that allowed a tracing process (e.g. gdb) to write 313 to a memory-mapped file in the traced process's address space 314 even if neither the traced process nor the tracing process had 315 write access to that file. 316 31720130605: 318 Added ZFS TRIM support which is enabled by default. To disable 319 ZFS TRIM support set vfs.zfs.trim.enabled=0 in loader.conf. 320 321 Creating new ZFS pools and adding new devices to existing pools 322 first performs a full device level TRIM which can take a significant 323 amount of time. The sysctl vfs.zfs.vdev.trim_on_init can be set to 0 324 to disable this behaviour. 325 326 ZFS TRIM requires the underlying device support BIO_DELETE which 327 is currently provided by methods such as ATA TRIM and SCSI UNMAP 328 via CAM, which are typically supported by SSD's. 329 330 Stats for ZFS TRIM can be monitored by looking at the sysctl's 331 under kstat.zfs.misc.zio_trim. 332 33320130524: 334 `list' command has been added to hastctl(8). For now, it is full 335 equivalent of `status' command. 336 WARNING: in the near future the output of hastctl's status command 337 will change to more terse format. If you use `hastctl status' 338 for parsing in your scripts, switch to `hastctl list'. 339 34020130430: 341 The mergemaster command now uses the default MAKEOBJDIRPREFIX 342 rather than creating it's own in the temporary directory in 343 order allow access to bootstrapped versions of tools such as 344 install and mtree. When upgrading from version of FreeBSD where 345 the install command does not support -l, you will need to 346 install a new mergemaster command if mergemaster -p is required. 347 This can be accomplished with the command (cd src/usr.sbin/mergemaster 348 && make install). 349 350 Due to the use of the new -l option to install(1) during build 351 and install, you must take care not to directly set the INSTALL 352 make variable in your /etc/make.conf, /etc/src.conf, or on the 353 command line. If you wish to use the -C flag for all installs 354 you may be able to add INSTALL+=-C to /etc/make.conf or 355 /etc/src.conf. 356 35720130429: 358 Fix a bug that allows NFS clients to issue READDIR on files. 359 36020130315: 361 The install(1) option -M has changed meaning and now takes an 362 argument that is a file or path to append logs to. In the 363 unlikely event that -M was the last option on the command line 364 and the command line contained at least two files and a target 365 directory the first file will have logs appended to it. The -M 366 option served little practical purpose in the last decade so it's 367 used expected to be extremely rare. 368 36920130225: 370 A new compression method (lz4) has been merged to. Please refer to 371 zpool-features(7) for more information. 372 373 Please refer to the "ZFS notes" section of this file for information 374 on upgrading boot ZFS pools. 375 37620121224: 377 The VFS KBI was changed with the merge of several nullfs 378 optimizations and fixes. All filesystem modules must be 379 recompiled. 380 38120121218: 382 With the addition of auditdistd(8), a new auditdistd user is now 383 depended on during installworld. "mergemaster -p" can be used to add 384 the user prior to installworld, as documented in the handbook. 385 38620121205: 387 9.1-RELEASE. 388 38920121129: 390 A new version of ZFS (pool version 5000) has been merged to 9-STABLE. 391 Starting with this version the old system of ZFS pool versioning 392 is superseded by "feature flags". This concept enables forward 393 compatibility against certain future changes in functionality of ZFS 394 pools. The first two read-only compatible "feature flags" for ZFS 395 pools are "com.delphix:async_destroy" and "com.delphix:empty_bpobj". 396 For more information read the new zpool-features(7) manual page. 397 Please refer to the "ZFS notes" section of this file for information 398 on upgrading boot ZFS pools. 399 40020121114: 401 The commit introducing bsd.compiler.mk breaks the traditional 402 building of kernels before this point. Add -m ${SRC}/share/mk 403 (for the right value of SRC) to your command lines to work 404 around; update your useland to a point after this; or use the 405 buildkernel/installkernel top-level targets. See also 20120829. 406 40720121102: 408 The IPFIREWALL_FORWARD kernel option has been removed. Its 409 functionality now turned on by default. 410 41120120913: 412 The random(4) support for the VIA hardware random number 413 generator (`PADLOCK') is no longer enabled unconditionally. 414 Add the PADLOCK_RNG option in the custom kernel config if 415 needed. The GENERIC kernels on i386 and amd64 do include the 416 option, so the change only affects the custom kernel 417 configurations. 418 41920120829: 420 The amd64 kernel now uses xsetbv, xrstor instructions. To compile with 421 the traditional method, you must update your system with an installworld 422 before the kernel will build. The documented make buildkernel/installkernel 423 interfaces (coupled with fresh make kernel-toolchain) continue to work. 424 42520120727: 426 The sparc64 ZFS loader has been changed to no longer try to auto- 427 detect ZFS providers based on diskN aliases but now requires these 428 to be explicitly listed in the OFW boot-device environment variable. 429 43020120422: 431 Now unix domain sockets behave "as expected" on nullfs(5). Previously 432 nullfs(5) did not pass through all behaviours to the underlying layer, 433 as a result if we bound to a socket on the lower layer we could connect 434 only to the lower path; if we bound to the upper layer we could connect 435 only to the upper path. The new behavior is one can connect to both the 436 lower and the upper paths regardless what layer path one binds to. 437 43820120109: 439 The acpi_wmi(4) status device /dev/wmistat has been renamed to 440 /dev/wmistat0. 441 44220120106: 443 A new VOP_ADVISE() was added to support posix_fadvise(2). All 444 filesystem modules must be recompiled. 445 44620120106: 447 The interface of the VOP_VPTOCNP(9) changed, now the returned 448 vnode shall be referenced, previously it was required to be 449 only held. All in-tree filesystems are converted. 450 45120120106: 452 9.0-RELEASE. 453 45420111101: 455 The broken amd(4) driver has been replaced with esp(4) in the amd64, 456 i386 and pc98 GENERIC kernel configuration files. 457 45820110913: 459 This commit modifies vfs_register() so that it uses a hash 460 calculation to set vfc_typenum, which is enabled by default. 461 The first time a system is booted after this change, the 462 vfc_typenum values will change for all file systems. The 463 main effect of this is a change to the NFS server file handles 464 for file systems that use vfc_typenum in their fsid, such as ZFS. 465 It will, however, prevent vfc_typenum from changing when file 466 systems are loaded in a different order for subsequent reboots. 467 To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf 468 until you are ready to remount all NFS clients after a reboot. 469 47020110828: 471 Bump the shared library version numbers for libraries that 472 do not use symbol versioning, have changed the ABI compared 473 to stable/8 and which shared library version was not bumped. 474 Done as part of 9.0-RELEASE cycle. 475 47620110815: 477 During the merge of Capsicum features, the fget(9) KPI was modified. 478 This may require the rebuilding of out-of-tree device drivers -- 479 issues have been reported specifically with the nVidia device driver. 480 __FreeBSD_version is bumped to 900041. 481 482 Also, there is a period between 20110811 and 20110814 where the 483 special devices /dev/{stdin,stdout,stderr} did not work correctly. 484 Building world from a kernel during that window may not work. 485 48620110628: 487 The packet filter (pf) code has been updated to OpenBSD 4.5. 488 You need to update userland tools to be in sync with kernel. 489 This update breaks backward compatibility with earlier pfsync(4) 490 versions. Care must be taken when updating redundant firewall setups. 491 49220110608: 493 The following sysctls and tunables are retired on x86 platforms: 494 machdep.hlt_cpus 495 machdep.hlt_logical_cpus 496 The following sysctl is retired: 497 machdep.hyperthreading_allowed 498 The sysctls were supposed to provide a way to dynamically offline and 499 online selected CPUs on x86 platforms, but the implementation has not 500 been reliable especially with SCHED_ULE scheduler. 501 machdep.hyperthreading_allowed tunable is still available to ignore 502 hyperthreading CPUs at OS level. 503 Individual CPUs can be disabled using hint.lapic.X.disabled tunable, 504 where X is an APIC ID of a CPU. Be advised, though, that disabling 505 CPUs in non-uniform fashion will result in non-uniform topology and 506 may lead to sub-optimal system performance with SCHED_ULE, which is 507 a default scheduler. 508 50920110607: 510 cpumask_t type is retired and cpuset_t is used in order to describe 511 a mask of CPUs. 512 51320110531: 514 Changes to ifconfig(8) for dynamic address family detection mandate 515 that you are running a kernel of 20110525 or later. Make sure to 516 follow the update procedure to boot a new kernel before installing 517 world. 518 51920110513: 520 Support for sun4v architecture is officially dropped 521 52220110503: 523 Several KPI breaking changes have been committed to the mii(4) layer, 524 the PHY drivers and consequently some Ethernet drivers using mii(4). 525 This means that miibus.ko and the modules of the affected Ethernet 526 drivers need to be recompiled. 527 528 Note to kernel developers: Given that the OUI bit reversion problem 529 was fixed as part of these changes all mii(4) commits related to OUIs, 530 i.e. to sys/dev/mii/miidevs, PHY driver probing and vendor specific 531 handling, no longer can be merged verbatim to stable/8 and previous 532 branches. 533 53420110430: 535 Users of the Atheros AR71xx SoC code now need to add 'device ar71xx_pci' 536 into their kernel configurations along with 'device pci'. 537 53820110427: 539 The default NFS client is now the new NFS client, so fstype "newnfs" 540 is now "nfs" and the regular/old NFS client is now fstype "oldnfs". 541 Although mounts via fstype "nfs" will usually work without userland 542 changes, it is recommended that the mount(8) and mount_nfs(8) 543 commands be rebuilt from sources and that a link to mount_nfs called 544 mount_oldnfs be created. The new client is compiled into the 545 kernel with "options NFSCL" and this is needed for diskless root 546 file systems. The GENERIC kernel configs have been changed to use 547 NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER. 548 To use the regular/old client, you can "mount -t oldnfs ...". For 549 a diskless root file system, you must also include a line like: 550 551 vfs.root.mountfrom="oldnfs:" 552 553 in the boot/loader.conf on the root fs on the NFS server to make 554 a diskless root fs use the old client. 555 55620110424: 557 The GENERIC kernels for all architectures now default to the new 558 CAM-based ATA stack. It means that all legacy ATA drivers were 559 removed and replaced by respective CAM drivers. If you are using 560 ATA device names in /etc/fstab or other places, make sure to update 561 them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY, 562 where 'Y's are the sequential numbers starting from zero for each type 563 in order of detection, unless configured otherwise with tunables, 564 see cam(4)). There will be symbolic links created in /dev/ to map 565 old adX devices to the respective adaY. They should provide basic 566 compatibility for file systems mounting in most cases, but they do 567 not support old user-level APIs and do not have respective providers 568 in GEOM. Consider using updated management tools with new device names. 569 570 It is possible to load devices ahci, ata, siis and mvs as modules, 571 but option ATA_CAM should remain in kernel configuration to make ata 572 module work as CAM driver supporting legacy ATA controllers. Device ata 573 still can be used in modular fashion (atacore + ...). Modules atadisk 574 and atapi* are not used and won't affect operation in ATA_CAM mode. 575 Note that to use CAM-based ATA kernel should include CAM devices 576 scbus, pass, da (or explicitly ada), cd and optionally others. All of 577 them are parts of the cam module. 578 579 ataraid(4) functionality is now supported by the RAID GEOM class. 580 To use it you can load geom_raid kernel module and use graid(8) tool 581 for management. Instead of /dev/arX device names, use /dev/raid/rX. 582 583 No kernel config options or code have been removed, so if a problem 584 arises, please report it and optionally revert to the old ATA stack. 585 In order to do it you can remove from the kernel config: 586 options ATA_CAM 587 device ahci 588 device mvs 589 device siis 590 , and instead add back: 591 device atadisk # ATA disk drives 592 device ataraid # ATA RAID drives 593 device atapicd # ATAPI CDROM drives 594 device atapifd # ATAPI floppy drives 595 device atapist # ATAPI tape drives 596 59720110423: 598 The default NFS server has been changed to the new server, which 599 was referred to as the experimental server. If you need to switch 600 back to the old NFS server, you must now put the "-o" option on 601 both the mountd and nfsd commands. This can be done using the 602 mountd_flags and nfs_server_flags rc.conf variables until an 603 update to the rc scripts is committed, which is coming soon. 604 60520110418: 606 The GNU Objective-C runtime library (libobjc), and other Objective-C 607 related components have been removed from the base system. If you 608 require an Objective-C library, please use one of the available ports. 609 61020110331: 611 ath(4) has been split into bus- and device- modules. if_ath contains 612 the HAL, the TX rate control and the network device code. if_ath_pci 613 contains the PCI bus glue. For Atheros MIPS embedded systems, if_ath_ahb 614 contains the AHB glue. Users need to load both if_ath_pci and if_ath 615 in order to use ath on everything else. 616 617 TO REPEAT: if_ath_ahb is not needed for normal users. Normal users only 618 need to load if_ath and if_ath_pci for ath(4) operation. 619 62020110314: 621 As part of the replacement of sysinstall, the process of building 622 release media has changed significantly. For details, please re-read 623 release(7), which has been updated to reflect the new build process. 624 62520110218: 626 GNU binutils 2.17.50 (as of 2007-07-03) has been merged to -HEAD. This 627 is the last available version under GPLv2. It brings a number of new 628 features, such as support for newer x86 CPU's (with SSE-3, SSSE-3, SSE 629 4.1 and SSE 4.2), better support for powerpc64, a number of new 630 directives, and lots of other small improvements. See the ChangeLog 631 file in contrib/binutils for the full details. 632 63320110218: 634 IPsec's HMAC_SHA256-512 support has been fixed to be RFC4868 635 compliant, and will now use half of hash for authentication. 636 This will break interoperability with all stacks (including all 637 actual FreeBSD versions) who implement 638 draft-ietf-ipsec-ciph-sha-256-00 (they use 96 bits of hash for 639 authentication). 640 The only workaround with such peers is to use another HMAC 641 algorithm for IPsec ("phase 2") authentication. 642 64320110207: 644 Remove the uio_yield prototype and symbol. This function has 645 been misnamed since it was introduced and should not be 646 globally exposed with this name. The equivalent functionality 647 is now available using kern_yield(curthread->td_user_pri). 648 The function remains undocumented. 649 65020110112: 651 A SYSCTL_[ADD_]UQUAD was added for unsigned uint64_t pointers, 652 symmetric with the existing SYSCTL_[ADD_]QUAD. Type checking 653 for scalar sysctls is defined but disabled. Code that needs 654 UQUAD to pass the type checking that must compile on older 655 systems where the define is not present can check against 656 __FreeBSD_version >= 900030. 657 658 The system dialog(1) has been replaced with a new version previously 659 in ports as devel/cdialog. dialog(1) is mostly command-line compatible 660 with the previous version, but the libdialog associated with it has 661 a largely incompatible API. As such, the original version of libdialog 662 will be kept temporarily as libodialog, until its base system consumers 663 are replaced or updated. Bump __FreeBSD_version to 900030. 664 66520110103: 666 If you are trying to run make universe on a -stable system, and you get 667 the following warning: 668 "Makefile", line 356: "Target architecture for i386/conf/GENERIC 669 unknown. config(8) likely too old." 670 or something similar to it, then you must upgrade your -stable system 671 to 8.2-Release or newer (really, any time after r210146 7/15/2010 in 672 stable/8) or build the config from the latest stable/8 branch and 673 install it on your system. 674 675 Prior to this date, building a current universe on 8-stable system from 676 between 7/15/2010 and 1/2/2011 would result in a weird shell parsing 677 error in the first kernel build phase. A new config on those old 678 systems will fix that problem for older versions of -current. 679 68020101228: 681 The TCP stack has been modified to allow Khelp modules to interact with 682 it via helper hook points and store per-connection data in the TCP 683 control block. Bump __FreeBSD_version to 900029. User space tools that 684 rely on the size of struct tcpcb in tcp_var.h (e.g. sockstat) need to 685 be recompiled. 686 68720101114: 688 Generic IEEE 802.3 annex 31B full duplex flow control support has been 689 added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along 690 with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted 691 to take advantage of it instead of using custom implementations. This 692 means that these drivers now no longer unconditionally advertise 693 support for flow control but only do so if flow control is a selected 694 media option. This was implemented in the generic support that way in 695 order to allow flow control to be switched on and off via ifconfig(8) 696 with the PHY specific default to typically off in order to protect 697 from unwanted effects. Consequently, if you used flow control with 698 one of the above mentioned drivers you now need to explicitly enable 699 it, for example via: 700 ifconfig bge0 media auto mediaopt flowcontrol 701 702 Along with the above mentioned changes generic support for setting 703 1000baseT master mode also has been added and brgphy(4), ciphy(4), 704 e1000phy(4) as well as ip1000phy(4) have been converted to take 705 advantage of it. This means that these drivers now no longer take the 706 link0 parameter for selecting master mode but the master media option 707 has to be used instead, for example like in the following: 708 ifconfig bge0 media 1000baseT mediaopt full-duplex,master 709 710 Selection of master mode now is also available with all other PHY 711 drivers supporting 1000baseT. 712 71320101111: 714 The TCP stack has received a significant update to add support for 715 modularised congestion control and generally improve the clarity of 716 congestion control decisions. Bump __FreeBSD_version to 900025. User 717 space tools that rely on the size of struct tcpcb in tcp_var.h (e.g. 718 sockstat) need to be recompiled. 719 72020101002: 721 The man(1) utility has been replaced by a new version that no longer 722 uses /etc/manpath.config. Please consult man.conf(5) for how to 723 migrate local entries to the new format. 724 72520100928: 726 The copyright strings printed by login(1) and sshd(8) at the time of a 727 new connection have been removed to follow other operating systems and 728 upstream sshd. 729 73020100915: 731 A workaround for a fixed ld bug has been removed in kernel code, 732 so make sure that your system ld is built from sources after 733 revision 210245 from 2010-07-19 (r211583 if building head kernel 734 on stable/8, r211584 for stable/7; both from 2010-08-21). 735 A symptom of incorrect ld version is different addresses for 736 set_pcpu section and __start_set_pcpu symbol in kernel and/or modules. 737 73820100913: 739 The $ipv6_prefer variable in rc.conf(5) has been split into 740 $ip6addrctl_policy and $ipv6_activate_all_interfaces. 741 742 The $ip6addrctl_policy is a variable to choose a pre-defined 743 address selection policy set by ip6addrctl(8). A value 744 "ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The 745 default is "AUTO". 746 747 The $ipv6_activate_all_interfaces specifies whether IFDISABLED 748 flag (see an entry of 20090926) is set on an interface with no 749 corresponding $ifconfig_IF_ipv6 line. The default is "NO" for 750 security reason. If you want IPv6 link-local address on all 751 interfaces by default, set this to "YES". 752 753 The old ipv6_prefer="YES" is equivalent to 754 ipv6_activate_all_interfaces="YES" and 755 ip6addrctl_policy="ipv6_prefer". 756 75720100913: 758 DTrace has grown support for userland tracing. Due to this, DTrace is 759 now i386 and amd64 only. 760 dtruss(1) is now installed by default on those systems and a new 761 kernel module is needed for userland tracing: fasttrap. 762 No changes to your kernel config file are necessary to enable 763 userland tracing, but you might consider adding 'STRIP=' and 764 'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want 765 to have informative userland stack traces in DTrace (ustack). 766 76720100725: 768 The acpi_aiboost(4) driver has been removed in favor of the new 769 aibs(4) driver. You should update your kernel configuration file. 770 77120100722: 772 BSD grep has been imported to the base system and it is built by 773 default. It is completely BSD licensed, highly GNU-compatible, uses 774 less memory than its GNU counterpart and has a small codebase. 775 However, it is slower than its GNU counterpart, which is mostly 776 noticeable for larger searches, for smaller ones it is measurable 777 but not significant. The reason is complex, the most important factor 778 is that we lack a modern and efficient regex library and GNU 779 overcomes this by optimizing the searches internally. Future work 780 on improving the regex performance is planned, for the meantime, 781 users that need better performance, can build GNU grep instead by 782 setting the WITH_GNU_GREP knob. 783 78420100713: 785 Due to the import of powerpc64 support, all existing powerpc kernel 786 configuration files must be updated with a machine directive like this: 787 machine powerpc powerpc 788 789 In addition, an updated config(8) is required to build powerpc kernels 790 after this change. 791 79220100713: 793 A new version of ZFS (version 15) has been merged to -HEAD. 794 This version uses a python library for the following subcommands: 795 zfs allow, zfs unallow, zfs groupspace, zfs userspace. 796 For full functionality of these commands the following port must 797 be installed: sysutils/py-zfs 798 79920100429: 800 'vm_page's are now hashed by physical address to an array of mutexes. 801 Currently this is only used to serialize access to hold_count. Over 802 time the page queue mutex will be peeled away. This changes the size 803 of pmap on every architecture. And requires all callers of vm_page_hold 804 and vm_page_unhold to be updated. 805 80620100402: 807 WITH_CTF can now be specified in src.conf (not recommended, there 808 are some problems with static executables), make.conf (would also 809 affect ports which do not use GNU make and do not override the 810 compile targets) or in the kernel config (via "makeoptions 811 WITH_CTF=yes"). 812 When WITH_CTF was specified there before this was silently ignored, 813 so make sure that WITH_CTF is not used in places which could lead 814 to unwanted behavior. 815 81620100311: 817 The kernel option COMPAT_IA32 has been replaced with COMPAT_FREEBSD32 818 to allow 32-bit compatibility on non-x86 platforms. All kernel 819 configurations on amd64 and ia64 platforms using these options must 820 be modified accordingly. 821 82220100113: 823 The utmp user accounting database has been replaced with utmpx, 824 the user accounting interface standardized by POSIX. 825 Unfortunately the semantics of utmp and utmpx don't match, 826 making it practically impossible to support both interfaces. 827 The user accounting database is used by tools like finger(1), 828 last(1), talk(1), w(1) and ac(8). 829 830 All applications in the base system use utmpx. This means only 831 local binaries (e.g. from the ports tree) may still use these 832 utmp database files. These applications must be rebuilt to make 833 use of utmpx. 834 835 After the system has been upgraded, it is safe to remove the old 836 log files (/var/run/utmp, /var/log/lastlog and /var/log/wtmp*), 837 assuming their contents is of no importance anymore. Old wtmp 838 databases can only be used by last(1) and ac(8) after they have 839 been converted to the new format using wtmpcvt(1). 840 84120100108: 842 Introduce the kernel thread "deadlock resolver" (which can be enabled 843 via the DEADLKRES option, see NOTES for more details) and the 844 sleepq_type() function for sleepqueues. 845 84620091202: 847 The rc.firewall and rc.firewall6 were unified, and 848 rc.firewall6 and rc.d/ip6fw were removed. 849 According to the removal of rc.d/ip6fw, ipv6_firewall_* rc 850 variables are obsoleted. Instead, the following new rc 851 variables are added to rc.d/ipfw: 852 853 firewall_client_net_ipv6, firewall_simple_iif_ipv6, 854 firewall_simple_inet_ipv6, firewall_simple_oif_ipv6, 855 firewall_simple_onet_ipv6, firewall_trusted_ipv6 856 857 The meanings correspond to the relevant IPv4 variables. 858 85920091125: 860 8.0-RELEASE. 861 86220091113: 863 The default terminal emulation for syscons(4) has been changed 864 from cons25 to xterm on all platforms except pc98. This means 865 that the /etc/ttys file needs to be updated to ensure correct 866 operation of applications on the console. 867 868 The terminal emulation style can be toggled per window by using 869 vidcontrol(1)'s -T flag. The TEKEN_CONS25 kernel configuration 870 options can be used to change the compile-time default back to 871 cons25. 872 873 To prevent graphical artifacts, make sure the TERM environment 874 variable is set to match the terminal emulation that is being 875 performed by syscons(4). 876 87720091109: 878 The layout of the structure ieee80211req_scan_result has changed. 879 Applications that require wireless scan results (e.g. ifconfig(8)) 880 from net80211 need to be recompiled. 881 882 Applications such as wpa_supplicant(8) may require a full world 883 build without using NO_CLEAN in order to get synchronized with the 884 new structure. 885 88620091025: 887 The iwn(4) driver has been updated to support the 5000 and 5150 series. 888 There's one kernel module for each firmware. Adding "device iwnfw" 889 to the kernel configuration file means including all three firmware 890 images inside the kernel. If you want to include just the one for 891 your wireless card, use the devices iwn4965fw, iwn5000fw or 892 iwn5150fw. 893 89420090926: 895 The rc.d/network_ipv6, IPv6 configuration script has been integrated 896 into rc.d/netif. The changes are the following: 897 898 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF 899 for IPv4. For aliases, $ifconfig_IF_aliasN should be used. 900 Note that both variables need the "inet6" keyword at the head. 901 902 Do not set $ipv6_network_interfaces manually if you do not 903 understand what you are doing. It is not needed in most cases. 904 905 $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but 906 they are obsolete. 907 908 2. $ipv6_enable is obsolete. Use $ipv6_prefer and 909 "inet6 accept_rtadv" keyword in ifconfig(8) instead. 910 911 If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and 912 all configured interfaces have "inet6 accept_rtadv" in the 913 $ifconfig_IF_ipv6. These are for backward compatibility. 914 915 3. A new variable $ipv6_prefer has been added. If NO, IPv6 916 functionality of interfaces with no corresponding 917 $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag, 918 and the default address selection policy of ip6addrctl(8) 919 is the IPv4-preferred one (see rc.d/ip6addrctl for more details). 920 Note that if you want to configure IPv6 functionality on the 921 disabled interfaces after boot, first you need to clear the flag by 922 using ifconfig(8) like: 923 924 ifconfig em0 inet6 -ifdisabled 925 926 If YES, the default address selection policy is set as 927 IPv6-preferred. 928 929 The default value of $ipv6_prefer is NO. 930 931 4. If your system need to receive Router Advertisement messages, 932 define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8) 933 scripts automatically invoke rtsol(8) when the interface becomes 934 UP. The Router Advertisement messages are used for SLAAC 935 (State-Less Address AutoConfiguration). 936 93720090922: 938 802.11s D3.03 support was committed. This is incompatible with the 939 previous code, which was based on D3.0. 940 94120090912: 942 A sysctl variable net.inet6.ip6.accept_rtadv now sets the default value 943 of a per-interface flag ND6_IFF_ACCEPT_RTADV, not a global knob to 944 control whether accepting Router Advertisement messages or not. 945 Also, a per-interface flag ND6_IFF_AUTO_LINKLOCAL has been added and 946 a sysctl variable net.inet6.ip6.auto_linklocal is its default value. 947 The ifconfig(8) utility now supports these flags. 948 94920090910: 950 ZFS snapshots are now mounted with MNT_IGNORE flag. Use -v option for 951 mount(8) and -a option for df(1) to see them. 952 95320090825: 954 The old tunable hw.bus.devctl_disable has been superseded by 955 hw.bus.devctl_queue. hw.bus.devctl_disable=1 in loader.conf should be 956 replaced by hw.bus.devctl_queue=0. The default for this new tunable 957 is 1000. 958 95920090813: 960 Remove the option STOP_NMI. The default action is now to use NMI only 961 for KDB via the newly introduced function stop_cpus_hard() and 962 maintain stop_cpus() to just use a normal IPI_STOP on ia32 and amd64. 963 96420090803: 965 The stable/8 branch created in subversion. This corresponds to the 966 RELENG_8 branch in CVS. 967 96820090719: 969 Bump the shared library version numbers for all libraries that do not 970 use symbol versioning as part of the 8.0-RELEASE cycle. Bump 971 __FreeBSD_version to 800105. 972 97320090714: 974 Due to changes in the implementation of virtual network stack support, 975 all network-related kernel modules must be recompiled. As this change 976 breaks the ABI, bump __FreeBSD_version to 800104. 977 97820090713: 979 The TOE interface to the TCP syncache has been modified to remove 980 struct tcpopt (<netinet/tcp_var.h>) from the ABI of the network stack. 981 The cxgb driver is the only TOE consumer affected by this change, and 982 needs to be recompiled along with the kernel. As this change breaks 983 the ABI, bump __FreeBSD_version to 800103. 984 98520090712: 986 Padding has been added to struct tcpcb, sackhint and tcpstat in 987 <netinet/tcp_var.h> to facilitate future MFCs and bug fixes whilst 988 maintaining the ABI. However, this change breaks the ABI, so bump 989 __FreeBSD_version to 800102. User space tools that rely on the size of 990 any of these structs (e.g. sockstat) need to be recompiled. 991 99220090630: 993 The NFS_LEGACYRPC option has been removed along with the old kernel 994 RPC implementation that this option selected. Kernel configurations 995 may need to be adjusted. 996 99720090629: 998 The network interface device nodes at /dev/net/<interface> have been 999 removed. All ioctl operations can be performed the normal way using 1000 routing sockets. The kqueue functionality can generally be replaced 1001 with routing sockets. 1002 100320090628: 1004 The documentation from the FreeBSD Documentation Project (Handbook, 1005 FAQ, etc.) is now installed via packages by sysinstall(8) and under 1006 the /usr/local/share/doc/freebsd directory instead of /usr/share/doc. 1007 100820090624: 1009 The ABI of various structures related to the SYSV IPC API have been 1010 changed. As a result, the COMPAT_FREEBSD[456] and COMPAT_43 kernel 1011 options now all require COMPAT_FREEBSD7. Bump __FreeBSD_version to 1012 800100. 1013 101420090622: 1015 Layout of struct vnet has changed as routing related variables were 1016 moved to their own Vimage module. Modules need to be recompiled. Bump 1017 __FreeBSD_version to 800099. 1018 101920090619: 1020 NGROUPS_MAX and NGROUPS have been increased from 16 to 1023 and 1024 1021 respectively. As long as no more than 16 groups per process are used, 1022 no changes should be visible. When more than 16 groups are used, old 1023 binaries may fail if they call getgroups() or getgrouplist() with 1024 statically sized storage. Recompiling will work around this, but 1025 applications should be modified to use dynamically allocated storage 1026 for group arrays as POSIX.1-2008 does not cap an implementation's 1027 number of supported groups at NGROUPS_MAX+1 as previous versions did. 1028 1029 NFS and portalfs mounts may also be affected as the list of groups is 1030 truncated to 16. Users of NFS who use more than 16 groups, should 1031 take care that negative group permissions are not used on the exported 1032 file systems as they will not be reliable unless a GSSAPI based 1033 authentication method is used. 1034 103520090616: 1036 The compiling option ADAPTIVE_LOCKMGRS has been introduced. This 1037 option compiles in the support for adaptive spinning for lockmgrs 1038 which want to enable it. The lockinit() function now accepts the flag 1039 LK_ADAPTIVE in order to make the lock object subject to adaptive 1040 spinning when both held in write and read mode. 1041 104220090613: 1043 The layout of the structure returned by IEEE80211_IOC_STA_INFO has 1044 changed. User applications that use this ioctl need to be rebuilt. 1045 104620090611: 1047 The layout of struct thread has changed. Kernel and modules need to 1048 be rebuilt. 1049 105020090608: 1051 The layout of structs ifnet, domain, protosw and vnet_net has changed. 1052 Kernel modules need to be rebuilt. Bump __FreeBSD_version to 800097. 1053 105420090602: 1055 window(1) has been removed from the base system. It can now be 1056 installed from ports. The port is called misc/window. 1057 105820090601: 1059 The way we are storing and accessing `routing table' entries has 1060 changed. Programs reading the FIB, like netstat, need to be 1061 re-compiled. 1062 106320090601: 1064 A new netisr implementation has been added for FreeBSD 8. Network 1065 file system modules, such as igmp, ipdivert, and others, should be 1066 rebuilt. 1067 Bump __FreeBSD_version to 800096. 1068 106920090530: 1070 Remove the tunable/sysctl debug.mpsafevfs as its initial purpose is no 1071 more valid. 1072 107320090530: 1074 Add VOP_ACCESSX(9). File system modules need to be rebuilt. 1075 Bump __FreeBSD_version to 800094. 1076 107720090529: 1078 Add mnt_xflag field to 'struct mount'. File system modules need to be 1079 rebuilt. 1080 Bump __FreeBSD_version to 800093. 1081 108220090528: 1083 The compiling option ADAPTIVE_SX has been retired while it has been 1084 introduced the option NO_ADAPTIVE_SX which handles the reversed logic. 1085 The KPI for sx_init_flags() changes as accepting flags: 1086 SX_ADAPTIVESPIN flag has been retired while the SX_NOADAPTIVE flag has 1087 been introduced in order to handle the reversed logic. 1088 Bump __FreeBSD_version to 800092. 1089 109020090527: 1091 Add support for hierarchical jails. Remove global securelevel. 1092 Bump __FreeBSD_version to 800091. 1093 109420090523: 1095 The layout of struct vnet_net has changed, therefore modules 1096 need to be rebuilt. 1097 Bump __FreeBSD_version to 800090. 1098 109920090523: 1100 The newly imported zic(8) produces a new format in the output. Please 1101 run tzsetup(8) to install the newly created data to /etc/localtime. 1102 110320090520: 1104 The sysctl tree for the usb stack has renamed from hw.usb2.* to 1105 hw.usb.* and is now consistent again with previous releases. 1106 110720090520: 1108 802.11 monitor mode support was revised and driver api's were changed. 1109 Drivers dependent on net80211 now support DLT_IEEE802_11_RADIO instead 1110 of DLT_IEEE802_11. No user-visible data structures were changed but 1111 applications that use DLT_IEEE802_11 may require changes. 1112 Bump __FreeBSD_version to 800088. 1113 111420090430: 1115 The layout of the following structs has changed: sysctl_oid, 1116 socket, ifnet, inpcbinfo, tcpcb, syncache_head, vnet_inet, 1117 vnet_inet6 and vnet_ipfw. Most modules need to be rebuild or 1118 panics may be experienced. World rebuild is required for 1119 correctly checking networking state from userland. 1120 Bump __FreeBSD_version to 800085. 1121 112220090429: 1123 MLDv2 and Source-Specific Multicast (SSM) have been merged 1124 to the IPv6 stack. VIMAGE hooks are in but not yet used. 1125 The implementation of SSM within FreeBSD's IPv6 stack closely 1126 follows the IPv4 implementation. 1127 1128 For kernel developers: 1129 1130 * The most important changes are that the ip6_output() and 1131 ip6_input() paths no longer take the IN6_MULTI_LOCK, 1132 and this lock has been downgraded to a non-recursive mutex. 1133 1134 * As with the changes to the IPv4 stack to support SSM, filtering 1135 of inbound multicast traffic must now be performed by transport 1136 protocols within the IPv6 stack. This does not apply to TCP and 1137 SCTP, however, it does apply to UDP in IPv6 and raw IPv6. 1138 1139 * The KPIs used by IPv6 multicast are similar to those used by 1140 the IPv4 stack, with the following differences: 1141 * im6o_mc_filter() is analogous to imo_multicast_filter(). 1142 * The legacy KAME entry points in6_joingroup and in6_leavegroup() 1143 are shimmed to in6_mc_join() and in6_mc_leave() respectively. 1144 * IN6_LOOKUP_MULTI() has been deprecated and removed. 1145 * IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs 1146 for MLDv1 have an additional 'timer' argument which is used to 1147 jitter the initial membership report for the solicited-node 1148 multicast membership on-link. 1149 * This is not strictly needed for MLDv2, which already jitters 1150 its report transmissions. However, the 'timer' argument is 1151 preserved in case MLDv1 is active on the interface. 1152 1153 * The KAME linked-list based IPv6 membership implementation has 1154 been refactored to use a vector similar to that used by the IPv4 1155 stack. 1156 Code which maintains a list of its own multicast memberships 1157 internally, e.g. carp, has been updated to reflect the new 1158 semantics. 1159 1160 * There is a known Lock Order Reversal (LOR) due to in6_setscope() 1161 acquiring the IF_AFDATA_LOCK and being called within ip6_output(). 1162 Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an 1163 implementation constraint which needs to be addressed in HEAD. 1164 1165 For application developers: 1166 1167 * The changes are broadly similar to those made for the IPv4 1168 stack. 1169 1170 * The use of IPv4 and IPv6 multicast socket options on the same 1171 socket, using mapped addresses, HAS NOT been tested or supported. 1172 1173 * There are a number of issues with the implementation of various 1174 IPv6 multicast APIs which need to be resolved in the API surface 1175 before the implementation is fully compatible with KAME userland 1176 use, and these are mostly to do with interface index treatment. 1177 1178 * The literature available discusses the use of either the delta / ASM 1179 API with setsockopt(2)/getsockopt(2), or the full-state / ASM API 1180 using setsourcefilter(3)/getsourcefilter(3). For more information 1181 please refer to RFC 3768, 'Socket Interface Extensions for 1182 Multicast Source Filters'. 1183 1184 * Applications which use the published RFC 3678 APIs should be fine. 1185 1186 For systems administrators: 1187 1188 * The mtest(8) utility has been refactored to support IPv6, in 1189 addition to IPv4. Interface addresses are no longer accepted 1190 as arguments, their names must be used instead. The utility 1191 will map the interface name to its first IPv4 address as 1192 returned by getifaddrs(3). 1193 1194 * The ifmcstat(8) utility has also been updated to print the MLDv2 1195 endpoint state and source filter lists via sysctl(3). 1196 1197 * The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable 1198 loopback of IPv6 multicast datagrams by default; it defaults to 1 1199 to preserve the existing behaviour. Disabling multicast loopback is 1200 recommended for optimal system performance. 1201 1202 * The IPv6 MROUTING code has been changed to examine this sysctl 1203 instead of attempting to perform a group lookup before looping 1204 back forwarded datagrams. 1205 1206 Bump __FreeBSD_version to 800084. 1207 120820090422: 1209 Implement low-level Bluetooth HCI API. 1210 Bump __FreeBSD_version to 800083. 1211 121220090419: 1213 The layout of struct malloc_type, used by modules to register new 1214 memory allocation types, has changed. Most modules will need to 1215 be rebuilt or panics may be experienced. 1216 Bump __FreeBSD_version to 800081. 1217 121820090415: 1219 Anticipate overflowing inp_flags - add inp_flags2. 1220 This changes most offsets in inpcb, so checking v4 connection 1221 state will require a world rebuild. 1222 Bump __FreeBSD_version to 800080. 1223 122420090415: 1225 Add an llentry to struct route and struct route_in6. Modules 1226 embedding a struct route will need to be recompiled. 1227 Bump __FreeBSD_version to 800079. 1228 122920090414: 1230 The size of rt_metrics_lite and by extension rtentry has changed. 1231 Networking administration apps will need to be recompiled. 1232 The route command now supports show as an alias for get, weighting 1233 of routes, sticky and nostick flags to alter the behavior of stateful 1234 load balancing. 1235 Bump __FreeBSD_version to 800078. 1236 123720090408: 1238 Do not use Giant for kbdmux(4) locking. This is wrong and 1239 apparently causing more problems than it solves. This will 1240 re-open the issue where interrupt handlers may race with 1241 kbdmux(4) in polling mode. Typical symptoms include (but 1242 not limited to) duplicated and/or missing characters when 1243 low level console functions (such as gets) are used while 1244 interrupts are enabled (for example geli password prompt, 1245 mountroot prompt etc.). Disabling kbdmux(4) may help. 1246 124720090407: 1248 The size of structs vnet_net, vnet_inet and vnet_ipfw has changed; 1249 kernel modules referencing any of the above need to be recompiled. 1250 Bump __FreeBSD_version to 800075. 1251 125220090320: 1253 GEOM_PART has become the default partition slicer for storage devices, 1254 replacing GEOM_MBR, GEOM_BSD, GEOM_PC98 and GEOM_GPT slicers. It 1255 introduces some changes: 1256 1257 MSDOS/EBR: the devices created from MSDOS extended partition entries 1258 (EBR) can be named differently than with GEOM_MBR and are now symlinks 1259 to devices with offset-based names. fstabs may need to be modified. 1260 1261 BSD: the "geometry does not match label" warning is harmless in most 1262 cases but it points to problems in file system misalignment with 1263 disk geometry. The "c" partition is now implicit, covers the whole 1264 top-level drive and cannot be (mis)used by users. 1265 1266 General: Kernel dumps are now not allowed to be written to devices 1267 whose partition types indicate they are meant to be used for file 1268 systems (or, in case of MSDOS partitions, as something else than 1269 the "386BSD" type). 1270 1271 Most of these changes date approximately from 200812. 1272 127320090319: 1274 The uscanner(4) driver has been removed from the kernel. This follows 1275 Linux removing theirs in 2.6 and making libusb the default interface 1276 (supported by sane). 1277 127820090319: 1279 The multicast forwarding code has been cleaned up. netstat(1) 1280 only relies on KVM now for printing bandwidth upcall meters. 1281 The IPv4 and IPv6 modules are split into ip_mroute_mod and 1282 ip6_mroute_mod respectively. The config(5) options for statically 1283 compiling this code remain the same, i.e. 'options MROUTING'. 1284 128520090315: 1286 Support for the IFF_NEEDSGIANT network interface flag has been 1287 removed, which means that non-MPSAFE network device drivers are no 1288 longer supported. In particular, if_ar, if_sr, and network device 1289 drivers from the old (legacy) USB stack can no longer be built or 1290 used. 1291 129220090313: 1293 POSIX.1 Native Language Support (NLS) has been enabled in libc and 1294 a bunch of new language catalog files have also been added. 1295 This means that some common libc messages are now localized and 1296 they depend on the LC_MESSAGES environmental variable. 1297 129820090313: 1299 The k8temp(4) driver has been renamed to amdtemp(4) since 1300 support for Family 10 and Family 11 CPU families was added. 1301 130220090309: 1303 IGMPv3 and Source-Specific Multicast (SSM) have been merged 1304 to the IPv4 stack. VIMAGE hooks are in but not yet used. 1305 1306 For kernel developers, the most important changes are that the 1307 ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(), 1308 and this lock has been downgraded to a non-recursive mutex. 1309 1310 Transport protocols (UDP, Raw IP) are now responsible for filtering 1311 inbound multicast traffic according to group membership and source 1312 filters. The imo_multicast_filter() KPI exists for this purpose. 1313 Transports which do not use multicast (SCTP, TCP) already reject 1314 multicast by default. Forwarding and receive performance may improve 1315 as a mutex acquisition is no longer needed in the ip_input() 1316 low-level input path. in_addmulti() and in_delmulti() are shimmed 1317 to new KPIs which exist to support SSM in-kernel. 1318 1319 For application developers, it is recommended that loopback of 1320 multicast datagrams be disabled for best performance, as this 1321 will still cause the lock to be taken for each looped-back 1322 datagram transmission. The net.inet.ip.mcast.loop sysctl may 1323 be tuned to 0 to disable loopback by default; it defaults to 1 1324 to preserve the existing behaviour. 1325 1326 For systems administrators, to obtain best performance with 1327 multicast reception and multiple groups, it is always recommended 1328 that a card with a suitably precise hash filter is used. Hash 1329 collisions will still result in the lock being taken within the 1330 transport protocol input path to check group membership. 1331 1332 If deploying FreeBSD in an environment with IGMP snooping switches, 1333 it is recommended that the net.inet.igmp.sendlocal sysctl remain 1334 enabled; this forces 224.0.0.0/24 group membership to be announced 1335 via IGMP. 1336 1337 The size of 'struct igmpstat' has changed; netstat needs to be 1338 recompiled to reflect this. 1339 Bump __FreeBSD_version to 800070. 1340 134120090309: 1342 libusb20.so.1 is now installed as libusb.so.1 and the ports system 1343 updated to use it. This requires a buildworld/installworld in order to 1344 update the library and dependencies (usbconfig, etc). Its advisable to 1345 rebuild all ports which uses libusb. More specific directions are given 1346 in the ports collection UPDATING file. Any /etc/libmap.conf entries for 1347 libusb are no longer required and can be removed. 1348 134920090302: 1350 A workaround is committed to allow the creation of System V shared 1351 memory segment of size > 2 GB on the 64-bit architectures. 1352 Due to a limitation of the existing ABI, the shm_segsz member 1353 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is 1354 wrong for large segments. Note that limits must be explicitly 1355 raised to allow such segments to be created. 1356 135720090301: 1358 The layout of struct ifnet has changed, requiring a rebuild of all 1359 network device driver modules. 1360 136120090227: 1362 The /dev handling for the new USB stack has changed, a 1363 buildworld/installworld is required for libusb20. 1364 136520090223: 1366 The new USB2 stack has now been permanently moved in and all kernel and 1367 module names reverted to their previous values (eg, usb, ehci, ohci, 1368 ums, ...). The old usb stack can be compiled in by prefixing the name 1369 with the letter 'o', the old usb modules have been removed. 1370 Updating entry 20090216 for xorg and 20090215 for libmap may still 1371 apply. 1372 137320090217: 1374 The rc.conf(5) option if_up_delay has been renamed to 1375 defaultroute_delay to better reflect its purpose. If you have 1376 customized this setting in /etc/rc.conf you need to update it to 1377 use the new name. 1378 137920090216: 1380 xorg 7.4 wants to configure its input devices via hald which does not 1381 yet work with USB2. If the keyboard/mouse does not work in xorg then 1382 add 1383 Option "AllowEmptyInput" "off" 1384 to your ServerLayout section. This will cause X to use the configured 1385 kbd and mouse sections from your xorg.conf. 1386 138720090215: 1388 The GENERIC kernels for all architectures now default to the new USB2 1389 stack. No kernel config options or code have been removed so if a 1390 problem arises please report it and optionally revert to the old USB 1391 stack. If you are loading USB kernel modules or have a custom kernel 1392 that includes GENERIC then ensure that usb names are also changed over, 1393 eg uftdi -> usb2_serial_ftdi. 1394 1395 Older programs linked against the ports libusb 0.1 need to be 1396 redirected to the new stack's libusb20. /etc/libmap.conf can 1397 be used for this: 1398 # Map old usb library to new one for usb2 stack 1399 libusb-0.1.so.8 libusb20.so.1 1400 140120090209: 1402 All USB ethernet devices now attach as interfaces under the name ueN 1403 (eg. ue0). This is to provide a predictable name as vendors often 1404 change usb chipsets in a product without notice. 1405 140620090203: 1407 The ichsmb(4) driver has been changed to require SMBus slave 1408 addresses be left-justified (xxxxxxx0b) rather than right-justified. 1409 All of the other SMBus controller drivers require left-justified 1410 slave addresses, so this change makes all the drivers provide the 1411 same interface. 1412 141320090201: 1414 INET6 statistics (struct ip6stat) was updated. 1415 netstat(1) needs to be recompiled. 1416 141720090119: 1418 NTFS has been removed from GENERIC kernel on amd64 to match 1419 GENERIC on i386. Should not cause any issues since mount_ntfs(8) 1420 will load ntfs.ko module automatically when NTFS support is 1421 actually needed, unless ntfs.ko is not installed or security 1422 level prohibits loading kernel modules. If either is the case, 1423 "options NTFS" has to be added into kernel config. 1424 142520090115: 1426 TCP Appropriate Byte Counting (RFC 3465) support added to kernel. 1427 New field in struct tcpcb breaks ABI, so bump __FreeBSD_version to 1428 800061. User space tools that rely on the size of struct tcpcb in 1429 tcp_var.h (e.g. sockstat) need to be recompiled. 1430 143120081225: 1432 ng_tty(4) module updated to match the new TTY subsystem. 1433 Due to API change, user-level applications must be updated. 1434 New API support added to mpd5 CVS and expected to be present 1435 in next mpd5.3 release. 1436 143720081219: 1438 With __FreeBSD_version 800060 the makefs tool is part of 1439 the base system (it was a port). 1440 144120081216: 1442 The afdata and ifnet locks have been changed from mutexes to 1443 rwlocks, network modules will need to be re-compiled. 1444 144520081214: 1446 __FreeBSD_version 800059 incorporates the new arp-v2 rewrite. 1447 RTF_CLONING, RTF_LLINFO and RTF_WASCLONED flags are eliminated. 1448 The new code reduced struct rtentry{} by 16 bytes on 32-bit 1449 architecture and 40 bytes on 64-bit architecture. The userland 1450 applications "arp" and "ndp" have been updated accordingly. 1451 The output from "netstat -r" shows only routing entries and 1452 none of the L2 information. 1453 145420081130: 1455 __FreeBSD_version 800057 marks the switchover from the 1456 binary ath hal to source code. Users must add the line: 1457 1458 options AH_SUPPORT_AR5416 1459 1460 to their kernel config files when specifying: 1461 1462 device ath_hal 1463 1464 The ath_hal module no longer exists; the code is now compiled 1465 together with the driver in the ath module. It is now 1466 possible to tailor chip support (i.e. reduce the set of chips 1467 and thereby the code size); consult ath_hal(4) for details. 1468 146920081121: 1470 __FreeBSD_version 800054 adds memory barriers to 1471 <machine/atomic.h>, new interfaces to ifnet to facilitate 1472 multiple hardware transmit queues for cards that support 1473 them, and a lock-less ring-buffer implementation to 1474 enable drivers to more efficiently manage queueing of 1475 packets. 1476 147720081117: 1478 A new version of ZFS (version 13) has been merged to -HEAD. 1479 This version has zpool attribute "listsnapshots" off by 1480 default, which means "zfs list" does not show snapshots, 1481 and is the same as Solaris behavior. 1482 148320081028: 1484 dummynet(4) ABI has changed. ipfw(8) needs to be recompiled. 1485 148620081009: 1487 The uhci, ohci, ehci and slhci USB Host controller drivers have 1488 been put into separate modules. If you load the usb module 1489 separately through loader.conf you will need to load the 1490 appropriate *hci module as well. E.g. for a UHCI-based USB 2.0 1491 controller add the following to loader.conf: 1492 1493 uhci_load="YES" 1494 ehci_load="YES" 1495 149620081009: 1497 The ABI used by the PMC toolset has changed. Please keep 1498 userland (libpmc(3)) and the kernel module (hwpmc(4)) in 1499 sync. 1500 150120081009: 1502 atapci kernel module now includes only generic PCI ATA 1503 driver. AHCI driver moved to ataahci kernel module. 1504 All vendor-specific code moved into separate kernel modules: 1505 ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, 1506 atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, 1507 atamarvell, atamicron, atanational, atanetcell, atanvidia, 1508 atapromise, ataserverworks, atasiliconimage, atasis, atavia 1509 151020080820: 1511 The TTY subsystem of the kernel has been replaced by a new 1512 implementation, which provides better scalability and an 1513 improved driver model. Most common drivers have been migrated to 1514 the new TTY subsystem, while others have not. The following 1515 drivers have not yet been ported to the new TTY layer: 1516 1517 PCI/ISA: 1518 cy, digi, rc, rp, sio 1519 1520 USB: 1521 ubser, ucycom 1522 1523 Line disciplines: 1524 ng_h4, ng_tty, ppp, sl, snp 1525 1526 Adding these drivers to your kernel configuration file shall 1527 cause compilation to fail. 1528 152920080818: 1530 ntpd has been upgraded to 4.2.4p5. 1531 153220080801: 1533 OpenSSH has been upgraded to 5.1p1. 1534 1535 For many years, FreeBSD's version of OpenSSH preferred DSA 1536 over RSA for host and user authentication keys. With this 1537 upgrade, we've switched to the vendor's default of RSA over 1538 DSA. This may cause upgraded clients to warn about unknown 1539 host keys even for previously known hosts. Users should 1540 follow the usual procedure for verifying host keys before 1541 accepting the RSA key. 1542 1543 This can be circumvented by setting the "HostKeyAlgorithms" 1544 option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh 1545 command line. 1546 1547 Please note that the sequence of keys offered for 1548 authentication has been changed as well. You may want to 1549 specify IdentityFile in a different order to revert this 1550 behavior. 1551 155220080713: 1553 The sio(4) driver has been removed from the i386 and amd64 1554 kernel configuration files. This means uart(4) is now the 1555 default serial port driver on those platforms as well. 1556 1557 To prevent collisions with the sio(4) driver, the uart(4) driver 1558 uses different names for its device nodes. This means the 1559 onboard serial port will now most likely be called "ttyu0" 1560 instead of "ttyd0". You may need to reconfigure applications to 1561 use the new device names. 1562 1563 When using the serial port as a boot console, be sure to update 1564 /boot/device.hints and /etc/ttys before booting the new kernel. 1565 If you forget to do so, you can still manually specify the hints 1566 at the loader prompt: 1567 1568 set hint.uart.0.at="isa" 1569 set hint.uart.0.port="0x3F8" 1570 set hint.uart.0.flags="0x10" 1571 set hint.uart.0.irq="4" 1572 boot -s 1573 157420080609: 1575 The gpt(8) utility has been removed. Use gpart(8) to partition 1576 disks instead. 1577 157820080603: 1579 The version that Linuxulator emulates was changed from 2.4.2 1580 to 2.6.16. If you experience any problems with Linux binaries 1581 please try to set sysctl compat.linux.osrelease to 2.4.2 and 1582 if it fixes the problem contact emulation mailing list. 1583 158420080525: 1585 ISDN4BSD (I4B) was removed from the src tree. You may need to 1586 update a your kernel configuration and remove relevant entries. 1587 158820080509: 1589 I have checked in code to support multiple routing tables. 1590 See the man pages setfib(1) and setfib(2). 1591 This is a hopefully backwards compatible version, 1592 but to make use of it you need to compile your kernel 1593 with options ROUTETABLES=2 (or more up to 16). 1594 159520080420: 1596 The 802.11 wireless support was redone to enable multi-bss 1597 operation on devices that are capable. The underlying device 1598 is no longer used directly but instead wlanX devices are 1599 cloned with ifconfig. This requires changes to rc.conf files. 1600 For example, change: 1601 ifconfig_ath0="WPA DHCP" 1602 to 1603 wlans_ath0=wlan0 1604 ifconfig_wlan0="WPA DHCP" 1605 see rc.conf(5) for more details. In addition, mergemaster of 1606 /etc/rc.d is highly recommended. Simultaneous update of userland 1607 and kernel wouldn't hurt either. 1608 1609 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta 1610 modules were merged into the base wlan module. All references 1611 to these modules (e.g. in kernel config files) must be removed. 1612 161320080408: 1614 psm(4) has gained write(2) support in native operation level. 1615 Arbitrary commands can be written to /dev/psm%d and status can 1616 be read back from it. Therefore, an application is responsible 1617 for status validation and error recovery. It is a no-op in 1618 other operation levels. 1619 162020080312: 1621 Support for KSE threading has been removed from the kernel. To 1622 run legacy applications linked against KSE libmap.conf may 1623 be used. The following libmap.conf may be used to ensure 1624 compatibility with any prior release: 1625 1626 libpthread.so.1 libthr.so.1 1627 libpthread.so.2 libthr.so.2 1628 libkse.so.3 libthr.so.3 1629 163020080301: 1631 The layout of struct vmspace has changed. This affects libkvm 1632 and any executables that link against libkvm and use the 1633 kvm_getprocs() function. In particular, but not exclusively, 1634 it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1). 1635 The effects are minimal, but it's advisable to upgrade world 1636 nonetheless. 1637 163820080229: 1639 The latest em driver no longer has support in it for the 1640 82575 adapter, this is now moved to the igb driver. The 1641 split was done to make new features that are incompatible 1642 with older hardware easier to do. 1643 164420080220: 1645 The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4), 1646 likewise the kernel option is now GEOM_LINUX_LVM. 1647 164820080211: 1649 The default NFS mount mode has changed from UDP to TCP for 1650 increased reliability. If you rely on (insecurely) NFS 1651 mounting across a firewall you may need to update your 1652 firewall rules. 1653 165420080208: 1655 Belatedly note the addition of m_collapse for compacting 1656 mbuf chains. 1657 165820080126: 1659 The fts(3) structures have been changed to use adequate 1660 integer types for their members and so to be able to cope 1661 with huge file trees. The old fts(3) ABI is preserved 1662 through symbol versioning in libc, so third-party binaries 1663 using fts(3) should still work, although they will not take 1664 advantage of the extended types. At the same time, some 1665 third-party software might fail to build after this change 1666 due to unportable assumptions made in its source code about 1667 fts(3) structure members. Such software should be fixed 1668 by its vendor or, in the worst case, in the ports tree. 1669 FreeBSD_version 800015 marks this change for the unlikely 1670 case that a portable fix is impossible. 1671 167220080123: 1673 To upgrade to -current after this date, you must be running 1674 FreeBSD not older than 6.0-RELEASE. Upgrading to -current 1675 from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems. 1676 167720071128: 1678 The ADAPTIVE_GIANT kernel option has been retired because its 1679 functionality is the default now. 1680 168120071118: 1682 The AT keyboard emulation of sunkbd(4) has been turned on 1683 by default. In order to make the special symbols of the Sun 1684 keyboards driven by sunkbd(4) work under X these now have 1685 to be configured the same way as Sun USB keyboards driven 1686 by ukbd(4) (which also does AT keyboard emulation), f.e.: 1687 1688 Option "XkbLayout" "us" 1689 Option "XkbRules" "xorg" 1690 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 1691 169220071024: 1693 It has been decided that it is desirable to provide ABI 1694 backwards compatibility to the FreeBSD 4/5/6 versions of the 1695 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 1696 broken with the introduction of PCI domain support (see the 1697 20070930 entry). Unfortunately, this required the ABI of 1698 PCIOCGETCONF to be broken again in order to be able to 1699 provide backwards compatibility to the old version of that 1700 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 1701 again. As for prominent ports this affects neither pciutils 1702 nor xorg-server this time, the hal port needs to be rebuilt 1703 however. 1704 170520071020: 1706 The misnamed kthread_create() and friends have been renamed 1707 to kproc_create() etc. Many of the callers already 1708 used kproc_start().. 1709 I will return kthread_create() and friends in a while 1710 with implementations that actually create threads, not procs. 1711 Renaming corresponds with version 800002. 1712 171320071010: 1714 RELENG_7 branched. 1715 1716COMMON ITEMS: 1717 1718 General Notes 1719 ------------- 1720 Avoid using make -j when upgrading. While generally safe, there are 1721 sometimes problems using -j to upgrade. If your upgrade fails with 1722 -j, please try again without -j. From time to time in the past there 1723 have been problems using -j with buildworld and/or installworld. This 1724 is especially true when upgrading between "distant" versions (eg one 1725 that cross a major release boundary or several minor releases, or when 1726 several months have passed on the -current branch). 1727 1728 Sometimes, obscure build problems are the result of environment 1729 poisoning. This can happen because the make utility reads its 1730 environment when searching for values for global variables. To run 1731 your build attempts in an "environmental clean room", prefix all make 1732 commands with 'env -i '. See the env(1) manual page for more details. 1733 1734 When upgrading from one major version to another it is generally best 1735 to upgrade to the latest code in the currently installed branch first, 1736 then do an upgrade to the new branch. This is the best-tested upgrade 1737 path, and has the highest probability of being successful. Please try 1738 this approach before reporting problems with a major version upgrade. 1739 1740 ZFS notes 1741 --------- 1742 When upgrading the boot ZFS pool to a new version, always follow 1743 these two steps: 1744 1745 1.) recompile and reinstall the ZFS boot loader and boot block 1746 (this is part of "make buildworld" and "make installworld") 1747 1748 2.) update the ZFS boot block on your boot drive 1749 1750 The following example updates the ZFS boot block on the first 1751 partition (freebsd-boot) of a GPT partitioned drive ad0: 1752 "gpart bootcode -p /boot/gptzfsboot -i 1 ad0" 1753 1754 Non-boot pools do not need these updates. 1755 1756 To build a kernel 1757 ----------------- 1758 If you are updating from a prior version of FreeBSD (even one just 1759 a few days old), you should follow this procedure. It is the most 1760 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1761 1762 make kernel-toolchain 1763 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1764 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1765 1766 To test a kernel once 1767 --------------------- 1768 If you just want to boot a kernel once (because you are not sure 1769 if it works, or if you want to boot a known bad kernel to provide 1770 debugging information) run 1771 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1772 nextboot -k testkernel 1773 1774 To just build a kernel when you know that it won't mess you up 1775 -------------------------------------------------------------- 1776 This assumes you are already running a CURRENT system. Replace 1777 ${arch} with the architecture of your machine (e.g. "i386", 1778 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1779 1780 cd src/sys/${arch}/conf 1781 config KERNEL_NAME_HERE 1782 cd ../compile/KERNEL_NAME_HERE 1783 make depend 1784 make 1785 make install 1786 1787 If this fails, go to the "To build a kernel" section. 1788 1789 To rebuild everything and install it on the current system. 1790 ----------------------------------------------------------- 1791 # Note: sometimes if you are running current you gotta do more than 1792 # is listed here if you are upgrading from a really old current. 1793 1794 <make sure you have good level 0 dumps> 1795 make buildworld 1796 make kernel KERNCONF=YOUR_KERNEL_HERE 1797 [1] 1798 <reboot in single user> [3] 1799 mergemaster -p [5] 1800 make installworld 1801 mergemaster -i [4] 1802 make delete-old [6] 1803 <reboot> 1804 1805 1806 To cross-install current onto a separate partition 1807 -------------------------------------------------- 1808 # In this approach we use a separate partition to hold 1809 # current's root, 'usr', and 'var' directories. A partition 1810 # holding "/", "/usr" and "/var" should be about 2GB in 1811 # size. 1812 1813 <make sure you have good level 0 dumps> 1814 <boot into -stable> 1815 make buildworld 1816 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1817 <maybe newfs current's root partition> 1818 <mount current's root partition on directory ${CURRENT_ROOT}> 1819 make installworld DESTDIR=${CURRENT_ROOT} 1820 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1821 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1822 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1823 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1824 <reboot into current> 1825 <do a "native" rebuild/install as described in the previous section> 1826 <maybe install compatibility libraries from ports/misc/compat*> 1827 <reboot> 1828 1829 1830 To upgrade in-place from stable to current 1831 ---------------------------------------------- 1832 <make sure you have good level 0 dumps> 1833 make buildworld [9] 1834 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1835 [1] 1836 <reboot in single user> [3] 1837 mergemaster -p [5] 1838 make installworld 1839 mergemaster -i [4] 1840 make delete-old [6] 1841 <reboot> 1842 1843 Make sure that you've read the UPDATING file to understand the 1844 tweaks to various things you need. At this point in the life 1845 cycle of current, things change often and you are on your own 1846 to cope. The defaults can also change, so please read ALL of 1847 the UPDATING entries. 1848 1849 Also, if you are tracking -current, you must be subscribed to 1850 freebsd-current@freebsd.org. Make sure that before you update 1851 your sources that you have read and understood all the recent 1852 messages there. If in doubt, please track -stable which has 1853 much fewer pitfalls. 1854 1855 [1] If you have third party modules, such as vmware, you 1856 should disable them at this point so they don't crash your 1857 system on reboot. 1858 1859 [3] From the bootblocks, boot -s, and then do 1860 fsck -p 1861 mount -u / 1862 mount -a 1863 cd src 1864 adjkerntz -i # if CMOS is wall time 1865 Also, when doing a major release upgrade, it is required that 1866 you boot into single user mode to do the installworld. 1867 1868 [4] Note: This step is non-optional. Failure to do this step 1869 can result in a significant reduction in the functionality of the 1870 system. Attempting to do it by hand is not recommended and those 1871 that pursue this avenue should read this file carefully, as well 1872 as the archives of freebsd-current and freebsd-hackers mailing lists 1873 for potential gotchas. The -U option is also useful to consider. 1874 See mergemaster(8) for more information. 1875 1876 [5] Usually this step is a noop. However, from time to time 1877 you may need to do this if you get unknown user in the following 1878 step. It never hurts to do it all the time. You may need to 1879 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1880 install) after the buildworld before this step if you last updated 1881 from [78]-stable or 9-stable before 20130430. 1882 1883 [6] This only deletes old files and directories. Old libraries 1884 can be deleted by "make delete-old-libs", but you have to make 1885 sure that no program is using those libraries anymore. 1886 1887 [8] In order to have a kernel that can run the 4.x binaries needed to 1888 do an installworld, you must include the COMPAT_FREEBSD4 option in 1889 your kernel. Failure to do so may leave you with a system that is 1890 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1891 required to run the 5.x binaries on more recent kernels. And so on 1892 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1893 1894 Make sure that you merge any new devices from GENERIC since the 1895 last time you updated your kernel config file. 1896 1897 [9] When checking out sources, you must include the -P flag to have 1898 cvs prune empty directories. 1899 1900 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1901 "?=" instead of the "=" assignment operator, so that buildworld can 1902 override the CPUTYPE if it needs to. 1903 1904 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1905 not on the command line, or in /etc/make.conf. buildworld will 1906 warn if it is improperly defined. 1907FORMAT: 1908 1909This file contains a list, in reverse chronological order, of major 1910breakages in tracking -current. It is not guaranteed to be a complete 1911list of such breakages, and only contains entries since October 10, 2007. 1912If you need to see UPDATING entries from before that date, you will need 1913to fetch an UPDATING file from an older FreeBSD release. 1914 1915Copyright information: 1916 1917Copyright 1998-2009 M.
