[SA-14:18] 353 35420140716: 355 9.3-RELEASE. 356 35720140608: 358 On i386 and amd64 systems, the onifconsole flag is now set by default 359 in /etc/ttys for ttyu0. This causes ttyu0 to be automatically enabled 360 as a login TTY if it is set in the bootloader as an active kernel 361 console. No changes in behavior should result otherwise. To revert to 362 the previous behavior, set ttyu0 to "off" in /etc/ttys. 363 36420140512: 365 Clang and llvm have been upgraded to 3.4.1 release. 366 36720140321: 368 Clang and llvm have been upgraded to 3.4 release. 369 37020140216: 371 The nve(4) driver for NVIDIA nForce MCP Ethernet adapters has 372 been deprecated and will not be part of FreeBSD 11.0 and later 373 releases. If you use this driver, please consider switching to 374 the nfe(4) driver instead. 375 37620131216: 377 The behavior of gss_pseudo_random() for the krb5 mechanism 378 has changed, for applications requesting a longer random string 379 than produced by the underlying enctype's pseudo-random() function. 380 In particular, the random string produced from a session key of 381 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 382 be different at the 17th octet and later, after this change. 383 The counter used in the PRF+ construction is now encoded as a 384 big-endian integer in accordance with RFC 4402. 385 __FreeBSD_version is bumped to 902505. 386 38720130930: 388 9.2-RELEASE. 389 39020130823: 391 Behavior of devfs rules path matching has been changed. 392 Pattern is now always matched against fully qualified devfs 393 path and slash characters must be explicitly matched by 394 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 395 subdirectories must be reviewed. 396 39720130705: 398 hastctl(8)'s `status' command output changed to terse one-liner format. 399 Scripts using this should switch to `list' command or be rewritten. 400 40120130618: 402 Fix a bug that allowed a tracing process (e.g. gdb) to write 403 to a memory-mapped file in the traced process's address space 404 even if neither the traced process nor the tracing process had 405 write access to that file. 406 40720130605: 408 Added ZFS TRIM support which is enabled by default. To disable 409 ZFS TRIM support set vfs.zfs.trim.enabled=0 in loader.conf. 410 411 Creating new ZFS pools and adding new devices to existing pools 412 first performs a full device level TRIM which can take a significant 413 amount of time. The sysctl vfs.zfs.vdev.trim_on_init can be set to 0 414 to disable this behaviour. 415 416 ZFS TRIM requires the underlying device support BIO_DELETE which 417 is currently provided by methods such as ATA TRIM and SCSI UNMAP 418 via CAM, which are typically supported by SSD's. 419 420 Stats for ZFS TRIM can be monitored by looking at the sysctl's 421 under kstat.zfs.misc.zio_trim. 422 42320130524: 424 `list' command has been added to hastctl(8). For now, it is full 425 equivalent of `status' command. 426 WARNING: in the near future the output of hastctl's status command 427 will change to more terse format. If you use `hastctl status' 428 for parsing in your scripts, switch to `hastctl list'. 429 43020130430: 431 The mergemaster command now uses the default MAKEOBJDIRPREFIX 432 rather than creating it's own in the temporary directory in 433 order allow access to bootstrapped versions of tools such as 434 install and mtree. When upgrading from version of FreeBSD where 435 the install command does not support -l, you will need to 436 install a new mergemaster command if mergemaster -p is required. 437 This can be accomplished with the command (cd src/usr.sbin/mergemaster 438 && make install). 439 440 Due to the use of the new -l option to install(1) during build 441 and install, you must take care not to directly set the INSTALL 442 make variable in your /etc/make.conf, /etc/src.conf, or on the 443 command line. If you wish to use the -C flag for all installs 444 you may be able to add INSTALL+=-C to /etc/make.conf or 445 /etc/src.conf. 446 44720130429: 448 Fix a bug that allows NFS clients to issue READDIR on files. 449 45020130315: 451 The install(1) option -M has changed meaning and now takes an 452 argument that is a file or path to append logs to. In the 453 unlikely event that -M was the last option on the command line 454 and the command line contained at least two files and a target 455 directory the first file will have logs appended to it. The -M 456 option served little practical purpose in the last decade so it's 457 used expected to be extremely rare. 458 45920130225: 460 A new compression method (lz4) has been merged to. Please refer to 461 zpool-features(7) for more information. 462 463 Please refer to the "ZFS notes" section of this file for information 464 on upgrading boot ZFS pools. 465 46620121224: 467 The VFS KBI was changed with the merge of several nullfs 468 optimizations and fixes. All filesystem modules must be 469 recompiled. 470 47120121218: 472 With the addition of auditdistd(8), a new auditdistd user is now 473 depended on during installworld. "mergemaster -p" can be used to add 474 the user prior to installworld, as documented in the handbook. 475 47620121205: 477 9.1-RELEASE. 478 47920121129: 480 A new version of ZFS (pool version 5000) has been merged to 9-STABLE. 481 Starting with this version the old system of ZFS pool versioning 482 is superseded by "feature flags". This concept enables forward 483 compatibility against certain future changes in functionality of ZFS 484 pools. The first two read-only compatible "feature flags" for ZFS 485 pools are "com.delphix:async_destroy" and "com.delphix:empty_bpobj". 486 For more information read the new zpool-features(7) manual page. 487 Please refer to the "ZFS notes" section of this file for information 488 on upgrading boot ZFS pools. 489 49020121114: 491 The commit introducing bsd.compiler.mk breaks the traditional 492 building of kernels before this point. Add -m ${SRC}/share/mk 493 (for the right value of SRC) to your command lines to work 494 around; update your useland to a point after this; or use the 495 buildkernel/installkernel top-level targets. See also 20120829. 496 49720121102: 498 The IPFIREWALL_FORWARD kernel option has been removed. Its 499 functionality now turned on by default. 500 50120120913: 502 The random(4) support for the VIA hardware random number 503 generator (`PADLOCK') is no longer enabled unconditionally. 504 Add the PADLOCK_RNG option in the custom kernel config if 505 needed. The GENERIC kernels on i386 and amd64 do include the 506 option, so the change only affects the custom kernel 507 configurations. 508 50920120829: 510 The amd64 kernel now uses xsetbv, xrstor instructions. To compile with 511 the traditional method, you must update your system with an installworld 512 before the kernel will build. The documented make buildkernel/installkernel 513 interfaces (coupled with fresh make kernel-toolchain) continue to work. 514 51520120727: 516 The sparc64 ZFS loader has been changed to no longer try to auto- 517 detect ZFS providers based on diskN aliases but now requires these 518 to be explicitly listed in the OFW boot-device environment variable. 519 52020120422: 521 Now unix domain sockets behave "as expected" on nullfs(5). Previously 522 nullfs(5) did not pass through all behaviours to the underlying layer, 523 as a result if we bound to a socket on the lower layer we could connect 524 only to the lower path; if we bound to the upper layer we could connect 525 only to the upper path. The new behavior is one can connect to both the 526 lower and the upper paths regardless what layer path one binds to. 527 52820120109: 529 The acpi_wmi(4) status device /dev/wmistat has been renamed to 530 /dev/wmistat0. 531 53220120106: 533 A new VOP_ADVISE() was added to support posix_fadvise(2). All 534 filesystem modules must be recompiled. 535 53620120106: 537 The interface of the VOP_VPTOCNP(9) changed, now the returned 538 vnode shall be referenced, previously it was required to be 539 only held. All in-tree filesystems are converted. 540 54120120106: 542 9.0-RELEASE. 543 54420111101: 545 The broken amd(4) driver has been replaced with esp(4) in the amd64, 546 i386 and pc98 GENERIC kernel configuration files. 547 54820110913: 549 This commit modifies vfs_register() so that it uses a hash 550 calculation to set vfc_typenum, which is enabled by default. 551 The first time a system is booted after this change, the 552 vfc_typenum values will change for all file systems. The 553 main effect of this is a change to the NFS server file handles 554 for file systems that use vfc_typenum in their fsid, such as ZFS. 555 It will, however, prevent vfc_typenum from changing when file 556 systems are loaded in a different order for subsequent reboots. 557 To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf 558 until you are ready to remount all NFS clients after a reboot. 559 56020110828: 561 Bump the shared library version numbers for libraries that 562 do not use symbol versioning, have changed the ABI compared 563 to stable/8 and which shared library version was not bumped. 564 Done as part of 9.0-RELEASE cycle. 565 56620110815: 567 During the merge of Capsicum features, the fget(9) KPI was modified. 568 This may require the rebuilding of out-of-tree device drivers -- 569 issues have been reported specifically with the nVidia device driver. 570 __FreeBSD_version is bumped to 900041. 571 572 Also, there is a period between 20110811 and 20110814 where the 573 special devices /dev/{stdin,stdout,stderr} did not work correctly. 574 Building world from a kernel during that window may not work. 575 57620110628: 577 The packet filter (pf) code has been updated to OpenBSD 4.5. 578 You need to update userland tools to be in sync with kernel. 579 This update breaks backward compatibility with earlier pfsync(4) 580 versions. Care must be taken when updating redundant firewall setups. 581 58220110608: 583 The following sysctls and tunables are retired on x86 platforms: 584 machdep.hlt_cpus 585 machdep.hlt_logical_cpus 586 The following sysctl is retired: 587 machdep.hyperthreading_allowed 588 The sysctls were supposed to provide a way to dynamically offline and 589 online selected CPUs on x86 platforms, but the implementation has not 590 been reliable especially with SCHED_ULE scheduler. 591 machdep.hyperthreading_allowed tunable is still available to ignore 592 hyperthreading CPUs at OS level. 593 Individual CPUs can be disabled using hint.lapic.X.disabled tunable, 594 where X is an APIC ID of a CPU. Be advised, though, that disabling 595 CPUs in non-uniform fashion will result in non-uniform topology and 596 may lead to sub-optimal system performance with SCHED_ULE, which is 597 a default scheduler. 598 59920110607: 600 cpumask_t type is retired and cpuset_t is used in order to describe 601 a mask of CPUs. 602 60320110531: 604 Changes to ifconfig(8) for dynamic address family detection mandate 605 that you are running a kernel of 20110525 or later. Make sure to 606 follow the update procedure to boot a new kernel before installing 607 world. 608 60920110513: 610 Support for sun4v architecture is officially dropped 611 61220110503: 613 Several KPI breaking changes have been committed to the mii(4) layer, 614 the PHY drivers and consequently some Ethernet drivers using mii(4). 615 This means that miibus.ko and the modules of the affected Ethernet 616 drivers need to be recompiled. 617 618 Note to kernel developers: Given that the OUI bit reversion problem 619 was fixed as part of these changes all mii(4) commits related to OUIs, 620 i.e. to sys/dev/mii/miidevs, PHY driver probing and vendor specific 621 handling, no longer can be merged verbatim to stable/8 and previous 622 branches. 623 62420110430: 625 Users of the Atheros AR71xx SoC code now need to add 'device ar71xx_pci' 626 into their kernel configurations along with 'device pci'. 627 62820110427: 629 The default NFS client is now the new NFS client, so fstype "newnfs" 630 is now "nfs" and the regular/old NFS client is now fstype "oldnfs". 631 Although mounts via fstype "nfs" will usually work without userland 632 changes, it is recommended that the mount(8) and mount_nfs(8) 633 commands be rebuilt from sources and that a link to mount_nfs called 634 mount_oldnfs be created. The new client is compiled into the 635 kernel with "options NFSCL" and this is needed for diskless root 636 file systems. The GENERIC kernel configs have been changed to use 637 NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER. 638 To use the regular/old client, you can "mount -t oldnfs ...". For 639 a diskless root file system, you must also include a line like: 640 641 vfs.root.mountfrom="oldnfs:" 642 643 in the boot/loader.conf on the root fs on the NFS server to make 644 a diskless root fs use the old client. 645 64620110424: 647 The GENERIC kernels for all architectures now default to the new 648 CAM-based ATA stack. It means that all legacy ATA drivers were 649 removed and replaced by respective CAM drivers. If you are using 650 ATA device names in /etc/fstab or other places, make sure to update 651 them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY, 652 where 'Y's are the sequential numbers starting from zero for each type 653 in order of detection, unless configured otherwise with tunables, 654 see cam(4)). There will be symbolic links created in /dev/ to map 655 old adX devices to the respective adaY. They should provide basic 656 compatibility for file systems mounting in most cases, but they do 657 not support old user-level APIs and do not have respective providers 658 in GEOM. Consider using updated management tools with new device names. 659 660 It is possible to load devices ahci, ata, siis and mvs as modules, 661 but option ATA_CAM should remain in kernel configuration to make ata 662 module work as CAM driver supporting legacy ATA controllers. Device ata 663 still can be used in modular fashion (atacore + ...). Modules atadisk 664 and atapi* are not used and won't affect operation in ATA_CAM mode. 665 Note that to use CAM-based ATA kernel should include CAM devices 666 scbus, pass, da (or explicitly ada), cd and optionally others. All of 667 them are parts of the cam module. 668 669 ataraid(4) functionality is now supported by the RAID GEOM class. 670 To use it you can load geom_raid kernel module and use graid(8) tool 671 for management. Instead of /dev/arX device names, use /dev/raid/rX. 672 673 No kernel config options or code have been removed, so if a problem 674 arises, please report it and optionally revert to the old ATA stack. 675 In order to do it you can remove from the kernel config: 676 options ATA_CAM 677 device ahci 678 device mvs 679 device siis 680 , and instead add back: 681 device atadisk # ATA disk drives 682 device ataraid # ATA RAID drives 683 device atapicd # ATAPI CDROM drives 684 device atapifd # ATAPI floppy drives 685 device atapist # ATAPI tape drives 686 68720110423: 688 The default NFS server has been changed to the new server, which 689 was referred to as the experimental server. If you need to switch 690 back to the old NFS server, you must now put the "-o" option on 691 both the mountd and nfsd commands. This can be done using the 692 mountd_flags and nfs_server_flags rc.conf variables until an 693 update to the rc scripts is committed, which is coming soon. 694 69520110418: 696 The GNU Objective-C runtime library (libobjc), and other Objective-C 697 related components have been removed from the base system. If you 698 require an Objective-C library, please use one of the available ports. 699 70020110331: 701 ath(4) has been split into bus- and device- modules. if_ath contains 702 the HAL, the TX rate control and the network device code. if_ath_pci 703 contains the PCI bus glue. For Atheros MIPS embedded systems, if_ath_ahb 704 contains the AHB glue. Users need to load both if_ath_pci and if_ath 705 in order to use ath on everything else. 706 707 TO REPEAT: if_ath_ahb is not needed for normal users. Normal users only 708 need to load if_ath and if_ath_pci for ath(4) operation. 709 71020110314: 711 As part of the replacement of sysinstall, the process of building 712 release media has changed significantly. For details, please re-read 713 release(7), which has been updated to reflect the new build process. 714 71520110218: 716 GNU binutils 2.17.50 (as of 2007-07-03) has been merged to -HEAD. This 717 is the last available version under GPLv2. It brings a number of new 718 features, such as support for newer x86 CPU's (with SSE-3, SSSE-3, SSE 719 4.1 and SSE 4.2), better support for powerpc64, a number of new 720 directives, and lots of other small improvements. See the ChangeLog 721 file in contrib/binutils for the full details. 722 72320110218: 724 IPsec's HMAC_SHA256-512 support has been fixed to be RFC4868 725 compliant, and will now use half of hash for authentication. 726 This will break interoperability with all stacks (including all 727 actual FreeBSD versions) who implement 728 draft-ietf-ipsec-ciph-sha-256-00 (they use 96 bits of hash for 729 authentication). 730 The only workaround with such peers is to use another HMAC 731 algorithm for IPsec ("phase 2") authentication. 732 73320110207: 734 Remove the uio_yield prototype and symbol. This function has 735 been misnamed since it was introduced and should not be 736 globally exposed with this name. The equivalent functionality 737 is now available using kern_yield(curthread->td_user_pri). 738 The function remains undocumented. 739 74020110112: 741 A SYSCTL_[ADD_]UQUAD was added for unsigned uint64_t pointers, 742 symmetric with the existing SYSCTL_[ADD_]QUAD. Type checking 743 for scalar sysctls is defined but disabled. Code that needs 744 UQUAD to pass the type checking that must compile on older 745 systems where the define is not present can check against 746 __FreeBSD_version >= 900030. 747 748 The system dialog(1) has been replaced with a new version previously 749 in ports as devel/cdialog. dialog(1) is mostly command-line compatible 750 with the previous version, but the libdialog associated with it has 751 a largely incompatible API. As such, the original version of libdialog 752 will be kept temporarily as libodialog, until its base system consumers 753 are replaced or updated. Bump __FreeBSD_version to 900030. 754 75520110103: 756 If you are trying to run make universe on a -stable system, and you get 757 the following warning: 758 "Makefile", line 356: "Target architecture for i386/conf/GENERIC 759 unknown. config(8) likely too old." 760 or something similar to it, then you must upgrade your -stable system 761 to 8.2-Release or newer (really, any time after r210146 7/15/2010 in 762 stable/8) or build the config from the latest stable/8 branch and 763 install it on your system. 764 765 Prior to this date, building a current universe on 8-stable system from 766 between 7/15/2010 and 1/2/2011 would result in a weird shell parsing 767 error in the first kernel build phase. A new config on those old 768 systems will fix that problem for older versions of -current. 769 77020101228: 771 The TCP stack has been modified to allow Khelp modules to interact with 772 it via helper hook points and store per-connection data in the TCP 773 control block. Bump __FreeBSD_version to 900029. User space tools that 774 rely on the size of struct tcpcb in tcp_var.h (e.g. sockstat) need to 775 be recompiled. 776 77720101114: 778 Generic IEEE 802.3 annex 31B full duplex flow control support has been 779 added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along 780 with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted 781 to take advantage of it instead of using custom implementations. This 782 means that these drivers now no longer unconditionally advertise 783 support for flow control but only do so if flow control is a selected 784 media option. This was implemented in the generic support that way in 785 order to allow flow control to be switched on and off via ifconfig(8) 786 with the PHY specific default to typically off in order to protect 787 from unwanted effects. Consequently, if you used flow control with 788 one of the above mentioned drivers you now need to explicitly enable 789 it, for example via: 790 ifconfig bge0 media auto mediaopt flowcontrol 791 792 Along with the above mentioned changes generic support for setting 793 1000baseT master mode also has been added and brgphy(4), ciphy(4), 794 e1000phy(4) as well as ip1000phy(4) have been converted to take 795 advantage of it. This means that these drivers now no longer take the 796 link0 parameter for selecting master mode but the master media option 797 has to be used instead, for example like in the following: 798 ifconfig bge0 media 1000baseT mediaopt full-duplex,master 799 800 Selection of master mode now is also available with all other PHY 801 drivers supporting 1000baseT. 802 80320101111: 804 The TCP stack has received a significant update to add support for 805 modularised congestion control and generally improve the clarity of 806 congestion control decisions. Bump __FreeBSD_version to 900025. User 807 space tools that rely on the size of struct tcpcb in tcp_var.h (e.g. 808 sockstat) need to be recompiled. 809 81020101002: 811 The man(1) utility has been replaced by a new version that no longer 812 uses /etc/manpath.config. Please consult man.conf(5) for how to 813 migrate local entries to the new format. 814 81520100928: 816 The copyright strings printed by login(1) and sshd(8) at the time of a 817 new connection have been removed to follow other operating systems and 818 upstream sshd. 819 82020100915: 821 A workaround for a fixed ld bug has been removed in kernel code, 822 so make sure that your system ld is built from sources after 823 revision 210245 from 2010-07-19 (r211583 if building head kernel 824 on stable/8, r211584 for stable/7; both from 2010-08-21). 825 A symptom of incorrect ld version is different addresses for 826 set_pcpu section and __start_set_pcpu symbol in kernel and/or modules. 827 82820100913: 829 The $ipv6_prefer variable in rc.conf(5) has been split into 830 $ip6addrctl_policy and $ipv6_activate_all_interfaces. 831 832 The $ip6addrctl_policy is a variable to choose a pre-defined 833 address selection policy set by ip6addrctl(8). A value 834 "ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The 835 default is "AUTO". 836 837 The $ipv6_activate_all_interfaces specifies whether IFDISABLED 838 flag (see an entry of 20090926) is set on an interface with no 839 corresponding $ifconfig_IF_ipv6 line. The default is "NO" for 840 security reason. If you want IPv6 link-local address on all 841 interfaces by default, set this to "YES". 842 843 The old ipv6_prefer="YES" is equivalent to 844 ipv6_activate_all_interfaces="YES" and 845 ip6addrctl_policy="ipv6_prefer". 846 84720100913: 848 DTrace has grown support for userland tracing. Due to this, DTrace is 849 now i386 and amd64 only. 850 dtruss(1) is now installed by default on those systems and a new 851 kernel module is needed for userland tracing: fasttrap. 852 No changes to your kernel config file are necessary to enable 853 userland tracing, but you might consider adding 'STRIP=' and 854 'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want 855 to have informative userland stack traces in DTrace (ustack). 856 85720100725: 858 The acpi_aiboost(4) driver has been removed in favor of the new 859 aibs(4) driver. You should update your kernel configuration file. 860 86120100722: 862 BSD grep has been imported to the base system and it is built by 863 default. It is completely BSD licensed, highly GNU-compatible, uses 864 less memory than its GNU counterpart and has a small codebase. 865 However, it is slower than its GNU counterpart, which is mostly 866 noticeable for larger searches, for smaller ones it is measurable 867 but not significant. The reason is complex, the most important factor 868 is that we lack a modern and efficient regex library and GNU 869 overcomes this by optimizing the searches internally. Future work 870 on improving the regex performance is planned, for the meantime, 871 users that need better performance, can build GNU grep instead by 872 setting the WITH_GNU_GREP knob. 873 87420100713: 875 Due to the import of powerpc64 support, all existing powerpc kernel 876 configuration files must be updated with a machine directive like this: 877 machine powerpc powerpc 878 879 In addition, an updated config(8) is required to build powerpc kernels 880 after this change. 881 88220100713: 883 A new version of ZFS (version 15) has been merged to -HEAD. 884 This version uses a python library for the following subcommands: 885 zfs allow, zfs unallow, zfs groupspace, zfs userspace. 886 For full functionality of these commands the following port must 887 be installed: sysutils/py-zfs 888 88920100429: 890 'vm_page's are now hashed by physical address to an array of mutexes. 891 Currently this is only used to serialize access to hold_count. Over 892 time the page queue mutex will be peeled away. This changes the size 893 of pmap on every architecture. And requires all callers of vm_page_hold 894 and vm_page_unhold to be updated. 895 89620100402: 897 WITH_CTF can now be specified in src.conf (not recommended, there 898 are some problems with static executables), make.conf (would also 899 affect ports which do not use GNU make and do not override the 900 compile targets) or in the kernel config (via "makeoptions 901 WITH_CTF=yes"). 902 When WITH_CTF was specified there before this was silently ignored, 903 so make sure that WITH_CTF is not used in places which could lead 904 to unwanted behavior. 905 90620100311: 907 The kernel option COMPAT_IA32 has been replaced with COMPAT_FREEBSD32 908 to allow 32-bit compatibility on non-x86 platforms. All kernel 909 configurations on amd64 and ia64 platforms using these options must 910 be modified accordingly. 911 91220100113: 913 The utmp user accounting database has been replaced with utmpx, 914 the user accounting interface standardized by POSIX. 915 Unfortunately the semantics of utmp and utmpx don't match, 916 making it practically impossible to support both interfaces. 917 The user accounting database is used by tools like finger(1), 918 last(1), talk(1), w(1) and ac(8). 919 920 All applications in the base system use utmpx. This means only 921 local binaries (e.g. from the ports tree) may still use these 922 utmp database files. These applications must be rebuilt to make 923 use of utmpx. 924 925 After the system has been upgraded, it is safe to remove the old 926 log files (/var/run/utmp, /var/log/lastlog and /var/log/wtmp*), 927 assuming their contents is of no importance anymore. Old wtmp 928 databases can only be used by last(1) and ac(8) after they have 929 been converted to the new format using wtmpcvt(1). 930 93120100108: 932 Introduce the kernel thread "deadlock resolver" (which can be enabled 933 via the DEADLKRES option, see NOTES for more details) and the 934 sleepq_type() function for sleepqueues. 935 93620091202: 937 The rc.firewall and rc.firewall6 were unified, and 938 rc.firewall6 and rc.d/ip6fw were removed. 939 According to the removal of rc.d/ip6fw, ipv6_firewall_* rc 940 variables are obsoleted. Instead, the following new rc 941 variables are added to rc.d/ipfw: 942 943 firewall_client_net_ipv6, firewall_simple_iif_ipv6, 944 firewall_simple_inet_ipv6, firewall_simple_oif_ipv6, 945 firewall_simple_onet_ipv6, firewall_trusted_ipv6 946 947 The meanings correspond to the relevant IPv4 variables. 948 94920091125: 950 8.0-RELEASE. 951 95220091113: 953 The default terminal emulation for syscons(4) has been changed 954 from cons25 to xterm on all platforms except pc98. This means 955 that the /etc/ttys file needs to be updated to ensure correct 956 operation of applications on the console. 957 958 The terminal emulation style can be toggled per window by using 959 vidcontrol(1)'s -T flag. The TEKEN_CONS25 kernel configuration 960 options can be used to change the compile-time default back to 961 cons25. 962 963 To prevent graphical artifacts, make sure the TERM environment 964 variable is set to match the terminal emulation that is being 965 performed by syscons(4). 966 96720091109: 968 The layout of the structure ieee80211req_scan_result has changed. 969 Applications that require wireless scan results (e.g. ifconfig(8)) 970 from net80211 need to be recompiled. 971 972 Applications such as wpa_supplicant(8) may require a full world 973 build without using NO_CLEAN in order to get synchronized with the 974 new structure. 975 97620091025: 977 The iwn(4) driver has been updated to support the 5000 and 5150 series. 978 There's one kernel module for each firmware. Adding "device iwnfw" 979 to the kernel configuration file means including all three firmware 980 images inside the kernel. If you want to include just the one for 981 your wireless card, use the devices iwn4965fw, iwn5000fw or 982 iwn5150fw. 983 98420090926: 985 The rc.d/network_ipv6, IPv6 configuration script has been integrated 986 into rc.d/netif. The changes are the following: 987 988 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF 989 for IPv4. For aliases, $ifconfig_IF_aliasN should be used. 990 Note that both variables need the "inet6" keyword at the head. 991 992 Do not set $ipv6_network_interfaces manually if you do not 993 understand what you are doing. It is not needed in most cases. 994 995 $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but 996 they are obsolete. 997 998 2. $ipv6_enable is obsolete. Use $ipv6_prefer and 999 "inet6 accept_rtadv" keyword in ifconfig(8) instead. 1000 1001 If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and 1002 all configured interfaces have "inet6 accept_rtadv" in the 1003 $ifconfig_IF_ipv6. These are for backward compatibility. 1004 1005 3. A new variable $ipv6_prefer has been added. If NO, IPv6 1006 functionality of interfaces with no corresponding 1007 $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag, 1008 and the default address selection policy of ip6addrctl(8) 1009 is the IPv4-preferred one (see rc.d/ip6addrctl for more details). 1010 Note that if you want to configure IPv6 functionality on the 1011 disabled interfaces after boot, first you need to clear the flag by 1012 using ifconfig(8) like: 1013 1014 ifconfig em0 inet6 -ifdisabled 1015 1016 If YES, the default address selection policy is set as 1017 IPv6-preferred. 1018 1019 The default value of $ipv6_prefer is NO. 1020 1021 4. If your system need to receive Router Advertisement messages, 1022 define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8) 1023 scripts automatically invoke rtsol(8) when the interface becomes 1024 UP. The Router Advertisement messages are used for SLAAC 1025 (State-Less Address AutoConfiguration). 1026 102720090922: 1028 802.11s D3.03 support was committed. This is incompatible with the 1029 previous code, which was based on D3.0. 1030 103120090912: 1032 A sysctl variable net.inet6.ip6.accept_rtadv now sets the default value 1033 of a per-interface flag ND6_IFF_ACCEPT_RTADV, not a global knob to 1034 control whether accepting Router Advertisement messages or not. 1035 Also, a per-interface flag ND6_IFF_AUTO_LINKLOCAL has been added and 1036 a sysctl variable net.inet6.ip6.auto_linklocal is its default value. 1037 The ifconfig(8) utility now supports these flags. 1038 103920090910: 1040 ZFS snapshots are now mounted with MNT_IGNORE flag. Use -v option for 1041 mount(8) and -a option for df(1) to see them. 1042 104320090825: 1044 The old tunable hw.bus.devctl_disable has been superseded by 1045 hw.bus.devctl_queue. hw.bus.devctl_disable=1 in loader.conf should be 1046 replaced by hw.bus.devctl_queue=0. The default for this new tunable 1047 is 1000. 1048 104920090813: 1050 Remove the option STOP_NMI. The default action is now to use NMI only 1051 for KDB via the newly introduced function stop_cpus_hard() and 1052 maintain stop_cpus() to just use a normal IPI_STOP on ia32 and amd64. 1053 105420090803: 1055 The stable/8 branch created in subversion. This corresponds to the 1056 RELENG_8 branch in CVS. 1057 105820090719: 1059 Bump the shared library version numbers for all libraries that do not 1060 use symbol versioning as part of the 8.0-RELEASE cycle. Bump 1061 __FreeBSD_version to 800105. 1062 106320090714: 1064 Due to changes in the implementation of virtual network stack support, 1065 all network-related kernel modules must be recompiled. As this change 1066 breaks the ABI, bump __FreeBSD_version to 800104. 1067 106820090713: 1069 The TOE interface to the TCP syncache has been modified to remove 1070 struct tcpopt (<netinet/tcp_var.h>) from the ABI of the network stack. 1071 The cxgb driver is the only TOE consumer affected by this change, and 1072 needs to be recompiled along with the kernel. As this change breaks 1073 the ABI, bump __FreeBSD_version to 800103. 1074 107520090712: 1076 Padding has been added to struct tcpcb, sackhint and tcpstat in 1077 <netinet/tcp_var.h> to facilitate future MFCs and bug fixes whilst 1078 maintaining the ABI. However, this change breaks the ABI, so bump 1079 __FreeBSD_version to 800102. User space tools that rely on the size of 1080 any of these structs (e.g. sockstat) need to be recompiled. 1081 108220090630: 1083 The NFS_LEGACYRPC option has been removed along with the old kernel 1084 RPC implementation that this option selected. Kernel configurations 1085 may need to be adjusted. 1086 108720090629: 1088 The network interface device nodes at /dev/net/<interface> have been 1089 removed. All ioctl operations can be performed the normal way using 1090 routing sockets. The kqueue functionality can generally be replaced 1091 with routing sockets. 1092 109320090628: 1094 The documentation from the FreeBSD Documentation Project (Handbook, 1095 FAQ, etc.) is now installed via packages by sysinstall(8) and under 1096 the /usr/local/share/doc/freebsd directory instead of /usr/share/doc. 1097 109820090624: 1099 The ABI of various structures related to the SYSV IPC API have been 1100 changed. As a result, the COMPAT_FREEBSD[456] and COMPAT_43 kernel 1101 options now all require COMPAT_FREEBSD7. Bump __FreeBSD_version to 1102 800100. 1103 110420090622: 1105 Layout of struct vnet has changed as routing related variables were 1106 moved to their own Vimage module. Modules need to be recompiled. Bump 1107 __FreeBSD_version to 800099. 1108 110920090619: 1110 NGROUPS_MAX and NGROUPS have been increased from 16 to 1023 and 1024 1111 respectively. As long as no more than 16 groups per process are used, 1112 no changes should be visible. When more than 16 groups are used, old 1113 binaries may fail if they call getgroups() or getgrouplist() with 1114 statically sized storage. Recompiling will work around this, but 1115 applications should be modified to use dynamically allocated storage 1116 for group arrays as POSIX.1-2008 does not cap an implementation's 1117 number of supported groups at NGROUPS_MAX+1 as previous versions did. 1118 1119 NFS and portalfs mounts may also be affected as the list of groups is 1120 truncated to 16. Users of NFS who use more than 16 groups, should 1121 take care that negative group permissions are not used on the exported 1122 file systems as they will not be reliable unless a GSSAPI based 1123 authentication method is used. 1124 112520090616: 1126 The compiling option ADAPTIVE_LOCKMGRS has been introduced. This 1127 option compiles in the support for adaptive spinning for lockmgrs 1128 which want to enable it. The lockinit() function now accepts the flag 1129 LK_ADAPTIVE in order to make the lock object subject to adaptive 1130 spinning when both held in write and read mode. 1131 113220090613: 1133 The layout of the structure returned by IEEE80211_IOC_STA_INFO has 1134 changed. User applications that use this ioctl need to be rebuilt. 1135 113620090611: 1137 The layout of struct thread has changed. Kernel and modules need to 1138 be rebuilt. 1139 114020090608: 1141 The layout of structs ifnet, domain, protosw and vnet_net has changed. 1142 Kernel modules need to be rebuilt. Bump __FreeBSD_version to 800097. 1143 114420090602: 1145 window(1) has been removed from the base system. It can now be 1146 installed from ports. The port is called misc/window. 1147 114820090601: 1149 The way we are storing and accessing `routing table' entries has 1150 changed. Programs reading the FIB, like netstat, need to be 1151 re-compiled. 1152 115320090601: 1154 A new netisr implementation has been added for FreeBSD 8. Network 1155 file system modules, such as igmp, ipdivert, and others, should be 1156 rebuilt. 1157 Bump __FreeBSD_version to 800096. 1158 115920090530: 1160 Remove the tunable/sysctl debug.mpsafevfs as its initial purpose is no 1161 more valid. 1162 116320090530: 1164 Add VOP_ACCESSX(9). File system modules need to be rebuilt. 1165 Bump __FreeBSD_version to 800094. 1166 116720090529: 1168 Add mnt_xflag field to 'struct mount'. File system modules need to be 1169 rebuilt. 1170 Bump __FreeBSD_version to 800093. 1171 117220090528: 1173 The compiling option ADAPTIVE_SX has been retired while it has been 1174 introduced the option NO_ADAPTIVE_SX which handles the reversed logic. 1175 The KPI for sx_init_flags() changes as accepting flags: 1176 SX_ADAPTIVESPIN flag has been retired while the SX_NOADAPTIVE flag has 1177 been introduced in order to handle the reversed logic. 1178 Bump __FreeBSD_version to 800092. 1179 118020090527: 1181 Add support for hierarchical jails. Remove global securelevel. 1182 Bump __FreeBSD_version to 800091. 1183 118420090523: 1185 The layout of struct vnet_net has changed, therefore modules 1186 need to be rebuilt. 1187 Bump __FreeBSD_version to 800090. 1188 118920090523: 1190 The newly imported zic(8) produces a new format in the output. Please 1191 run tzsetup(8) to install the newly created data to /etc/localtime. 1192 119320090520: 1194 The sysctl tree for the usb stack has renamed from hw.usb2.* to 1195 hw.usb.* and is now consistent again with previous releases. 1196 119720090520: 1198 802.11 monitor mode support was revised and driver api's were changed. 1199 Drivers dependent on net80211 now support DLT_IEEE802_11_RADIO instead 1200 of DLT_IEEE802_11. No user-visible data structures were changed but 1201 applications that use DLT_IEEE802_11 may require changes. 1202 Bump __FreeBSD_version to 800088. 1203 120420090430: 1205 The layout of the following structs has changed: sysctl_oid, 1206 socket, ifnet, inpcbinfo, tcpcb, syncache_head, vnet_inet, 1207 vnet_inet6 and vnet_ipfw. Most modules need to be rebuild or 1208 panics may be experienced. World rebuild is required for 1209 correctly checking networking state from userland. 1210 Bump __FreeBSD_version to 800085. 1211 121220090429: 1213 MLDv2 and Source-Specific Multicast (SSM) have been merged 1214 to the IPv6 stack. VIMAGE hooks are in but not yet used. 1215 The implementation of SSM within FreeBSD's IPv6 stack closely 1216 follows the IPv4 implementation. 1217 1218 For kernel developers: 1219 1220 * The most important changes are that the ip6_output() and 1221 ip6_input() paths no longer take the IN6_MULTI_LOCK, 1222 and this lock has been downgraded to a non-recursive mutex. 1223 1224 * As with the changes to the IPv4 stack to support SSM, filtering 1225 of inbound multicast traffic must now be performed by transport 1226 protocols within the IPv6 stack. This does not apply to TCP and 1227 SCTP, however, it does apply to UDP in IPv6 and raw IPv6. 1228 1229 * The KPIs used by IPv6 multicast are similar to those used by 1230 the IPv4 stack, with the following differences: 1231 * im6o_mc_filter() is analogous to imo_multicast_filter(). 1232 * The legacy KAME entry points in6_joingroup and in6_leavegroup() 1233 are shimmed to in6_mc_join() and in6_mc_leave() respectively. 1234 * IN6_LOOKUP_MULTI() has been deprecated and removed. 1235 * IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs 1236 for MLDv1 have an additional 'timer' argument which is used to 1237 jitter the initial membership report for the solicited-node 1238 multicast membership on-link. 1239 * This is not strictly needed for MLDv2, which already jitters 1240 its report transmissions. However, the 'timer' argument is 1241 preserved in case MLDv1 is active on the interface. 1242 1243 * The KAME linked-list based IPv6 membership implementation has 1244 been refactored to use a vector similar to that used by the IPv4 1245 stack. 1246 Code which maintains a list of its own multicast memberships 1247 internally, e.g. carp, has been updated to reflect the new 1248 semantics. 1249 1250 * There is a known Lock Order Reversal (LOR) due to in6_setscope() 1251 acquiring the IF_AFDATA_LOCK and being called within ip6_output(). 1252 Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an 1253 implementation constraint which needs to be addressed in HEAD. 1254 1255 For application developers: 1256 1257 * The changes are broadly similar to those made for the IPv4 1258 stack. 1259 1260 * The use of IPv4 and IPv6 multicast socket options on the same 1261 socket, using mapped addresses, HAS NOT been tested or supported. 1262 1263 * There are a number of issues with the implementation of various 1264 IPv6 multicast APIs which need to be resolved in the API surface 1265 before the implementation is fully compatible with KAME userland 1266 use, and these are mostly to do with interface index treatment. 1267 1268 * The literature available discusses the use of either the delta / ASM 1269 API with setsockopt(2)/getsockopt(2), or the full-state / ASM API 1270 using setsourcefilter(3)/getsourcefilter(3). For more information 1271 please refer to RFC 3768, 'Socket Interface Extensions for 1272 Multicast Source Filters'. 1273 1274 * Applications which use the published RFC 3678 APIs should be fine. 1275 1276 For systems administrators: 1277 1278 * The mtest(8) utility has been refactored to support IPv6, in 1279 addition to IPv4. Interface addresses are no longer accepted 1280 as arguments, their names must be used instead. The utility 1281 will map the interface name to its first IPv4 address as 1282 returned by getifaddrs(3). 1283 1284 * The ifmcstat(8) utility has also been updated to print the MLDv2 1285 endpoint state and source filter lists via sysctl(3). 1286 1287 * The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable 1288 loopback of IPv6 multicast datagrams by default; it defaults to 1 1289 to preserve the existing behaviour. Disabling multicast loopback is 1290 recommended for optimal system performance. 1291 1292 * The IPv6 MROUTING code has been changed to examine this sysctl 1293 instead of attempting to perform a group lookup before looping 1294 back forwarded datagrams. 1295 1296 Bump __FreeBSD_version to 800084. 1297 129820090422: 1299 Implement low-level Bluetooth HCI API. 1300 Bump __FreeBSD_version to 800083. 1301 130220090419: 1303 The layout of struct malloc_type, used by modules to register new 1304 memory allocation types, has changed. Most modules will need to 1305 be rebuilt or panics may be experienced. 1306 Bump __FreeBSD_version to 800081. 1307 130820090415: 1309 Anticipate overflowing inp_flags - add inp_flags2. 1310 This changes most offsets in inpcb, so checking v4 connection 1311 state will require a world rebuild. 1312 Bump __FreeBSD_version to 800080. 1313 131420090415: 1315 Add an llentry to struct route and struct route_in6. Modules 1316 embedding a struct route will need to be recompiled. 1317 Bump __FreeBSD_version to 800079. 1318 131920090414: 1320 The size of rt_metrics_lite and by extension rtentry has changed. 1321 Networking administration apps will need to be recompiled. 1322 The route command now supports show as an alias for get, weighting 1323 of routes, sticky and nostick flags to alter the behavior of stateful 1324 load balancing. 1325 Bump __FreeBSD_version to 800078. 1326 132720090408: 1328 Do not use Giant for kbdmux(4) locking. This is wrong and 1329 apparently causing more problems than it solves. This will 1330 re-open the issue where interrupt handlers may race with 1331 kbdmux(4) in polling mode. Typical symptoms include (but 1332 not limited to) duplicated and/or missing characters when 1333 low level console functions (such as gets) are used while 1334 interrupts are enabled (for example geli password prompt, 1335 mountroot prompt etc.). Disabling kbdmux(4) may help. 1336 133720090407: 1338 The size of structs vnet_net, vnet_inet and vnet_ipfw has changed; 1339 kernel modules referencing any of the above need to be recompiled. 1340 Bump __FreeBSD_version to 800075. 1341 134220090320: 1343 GEOM_PART has become the default partition slicer for storage devices, 1344 replacing GEOM_MBR, GEOM_BSD, GEOM_PC98 and GEOM_GPT slicers. It 1345 introduces some changes: 1346 1347 MSDOS/EBR: the devices created from MSDOS extended partition entries 1348 (EBR) can be named differently than with GEOM_MBR and are now symlinks 1349 to devices with offset-based names. fstabs may need to be modified. 1350 1351 BSD: the "geometry does not match label" warning is harmless in most 1352 cases but it points to problems in file system misalignment with 1353 disk geometry. The "c" partition is now implicit, covers the whole 1354 top-level drive and cannot be (mis)used by users. 1355 1356 General: Kernel dumps are now not allowed to be written to devices 1357 whose partition types indicate they are meant to be used for file 1358 systems (or, in case of MSDOS partitions, as something else than 1359 the "386BSD" type). 1360 1361 Most of these changes date approximately from 200812. 1362 136320090319: 1364 The uscanner(4) driver has been removed from the kernel. This follows 1365 Linux removing theirs in 2.6 and making libusb the default interface 1366 (supported by sane). 1367 136820090319: 1369 The multicast forwarding code has been cleaned up. netstat(1) 1370 only relies on KVM now for printing bandwidth upcall meters. 1371 The IPv4 and IPv6 modules are split into ip_mroute_mod and 1372 ip6_mroute_mod respectively. The config(5) options for statically 1373 compiling this code remain the same, i.e. 'options MROUTING'. 1374 137520090315: 1376 Support for the IFF_NEEDSGIANT network interface flag has been 1377 removed, which means that non-MPSAFE network device drivers are no 1378 longer supported. In particular, if_ar, if_sr, and network device 1379 drivers from the old (legacy) USB stack can no longer be built or 1380 used. 1381 138220090313: 1383 POSIX.1 Native Language Support (NLS) has been enabled in libc and 1384 a bunch of new language catalog files have also been added. 1385 This means that some common libc messages are now localized and 1386 they depend on the LC_MESSAGES environmental variable. 1387 138820090313: 1389 The k8temp(4) driver has been renamed to amdtemp(4) since 1390 support for Family 10 and Family 11 CPU families was added. 1391 139220090309: 1393 IGMPv3 and Source-Specific Multicast (SSM) have been merged 1394 to the IPv4 stack. VIMAGE hooks are in but not yet used. 1395 1396 For kernel developers, the most important changes are that the 1397 ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(), 1398 and this lock has been downgraded to a non-recursive mutex. 1399 1400 Transport protocols (UDP, Raw IP) are now responsible for filtering 1401 inbound multicast traffic according to group membership and source 1402 filters. The imo_multicast_filter() KPI exists for this purpose. 1403 Transports which do not use multicast (SCTP, TCP) already reject 1404 multicast by default. Forwarding and receive performance may improve 1405 as a mutex acquisition is no longer needed in the ip_input() 1406 low-level input path. in_addmulti() and in_delmulti() are shimmed 1407 to new KPIs which exist to support SSM in-kernel. 1408 1409 For application developers, it is recommended that loopback of 1410 multicast datagrams be disabled for best performance, as this 1411 will still cause the lock to be taken for each looped-back 1412 datagram transmission. The net.inet.ip.mcast.loop sysctl may 1413 be tuned to 0 to disable loopback by default; it defaults to 1 1414 to preserve the existing behaviour. 1415 1416 For systems administrators, to obtain best performance with 1417 multicast reception and multiple groups, it is always recommended 1418 that a card with a suitably precise hash filter is used. Hash 1419 collisions will still result in the lock being taken within the 1420 transport protocol input path to check group membership. 1421 1422 If deploying FreeBSD in an environment with IGMP snooping switches, 1423 it is recommended that the net.inet.igmp.sendlocal sysctl remain 1424 enabled; this forces 224.0.0.0/24 group membership to be announced 1425 via IGMP. 1426 1427 The size of 'struct igmpstat' has changed; netstat needs to be 1428 recompiled to reflect this. 1429 Bump __FreeBSD_version to 800070. 1430 143120090309: 1432 libusb20.so.1 is now installed as libusb.so.1 and the ports system 1433 updated to use it. This requires a buildworld/installworld in order to 1434 update the library and dependencies (usbconfig, etc). Its advisable to 1435 rebuild all ports which uses libusb. More specific directions are given 1436 in the ports collection UPDATING file. Any /etc/libmap.conf entries for 1437 libusb are no longer required and can be removed. 1438 143920090302: 1440 A workaround is committed to allow the creation of System V shared 1441 memory segment of size > 2 GB on the 64-bit architectures. 1442 Due to a limitation of the existing ABI, the shm_segsz member 1443 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is 1444 wrong for large segments. Note that limits must be explicitly 1445 raised to allow such segments to be created. 1446 144720090301: 1448 The layout of struct ifnet has changed, requiring a rebuild of all 1449 network device driver modules. 1450 145120090227: 1452 The /dev handling for the new USB stack has changed, a 1453 buildworld/installworld is required for libusb20. 1454 145520090223: 1456 The new USB2 stack has now been permanently moved in and all kernel and 1457 module names reverted to their previous values (eg, usb, ehci, ohci, 1458 ums, ...). The old usb stack can be compiled in by prefixing the name 1459 with the letter 'o', the old usb modules have been removed. 1460 Updating entry 20090216 for xorg and 20090215 for libmap may still 1461 apply. 1462 146320090217: 1464 The rc.conf(5) option if_up_delay has been renamed to 1465 defaultroute_delay to better reflect its purpose. If you have 1466 customized this setting in /etc/rc.conf you need to update it to 1467 use the new name. 1468 146920090216: 1470 xorg 7.4 wants to configure its input devices via hald which does not 1471 yet work with USB2. If the keyboard/mouse does not work in xorg then 1472 add 1473 Option "AllowEmptyInput" "off" 1474 to your ServerLayout section. This will cause X to use the configured 1475 kbd and mouse sections from your xorg.conf. 1476 147720090215: 1478 The GENERIC kernels for all architectures now default to the new USB2 1479 stack. No kernel config options or code have been removed so if a 1480 problem arises please report it and optionally revert to the old USB 1481 stack. If you are loading USB kernel modules or have a custom kernel 1482 that includes GENERIC then ensure that usb names are also changed over, 1483 eg uftdi -> usb2_serial_ftdi. 1484 1485 Older programs linked against the ports libusb 0.1 need to be 1486 redirected to the new stack's libusb20. /etc/libmap.conf can 1487 be used for this: 1488 # Map old usb library to new one for usb2 stack 1489 libusb-0.1.so.8 libusb20.so.1 1490 149120090209: 1492 All USB ethernet devices now attach as interfaces under the name ueN 1493 (eg. ue0). This is to provide a predictable name as vendors often 1494 change usb chipsets in a product without notice. 1495 149620090203: 1497 The ichsmb(4) driver has been changed to require SMBus slave 1498 addresses be left-justified (xxxxxxx0b) rather than right-justified. 1499 All of the other SMBus controller drivers require left-justified 1500 slave addresses, so this change makes all the drivers provide the 1501 same interface. 1502 150320090201: 1504 INET6 statistics (struct ip6stat) was updated. 1505 netstat(1) needs to be recompiled. 1506 150720090119: 1508 NTFS has been removed from GENERIC kernel on amd64 to match 1509 GENERIC on i386. Should not cause any issues since mount_ntfs(8) 1510 will load ntfs.ko module automatically when NTFS support is 1511 actually needed, unless ntfs.ko is not installed or security 1512 level prohibits loading kernel modules. If either is the case, 1513 "options NTFS" has to be added into kernel config. 1514 151520090115: 1516 TCP Appropriate Byte Counting (RFC 3465) support added to kernel. 1517 New field in struct tcpcb breaks ABI, so bump __FreeBSD_version to 1518 800061. User space tools that rely on the size of struct tcpcb in 1519 tcp_var.h (e.g. sockstat) need to be recompiled. 1520 152120081225: 1522 ng_tty(4) module updated to match the new TTY subsystem. 1523 Due to API change, user-level applications must be updated. 1524 New API support added to mpd5 CVS and expected to be present 1525 in next mpd5.3 release. 1526 152720081219: 1528 With __FreeBSD_version 800060 the makefs tool is part of 1529 the base system (it was a port). 1530 153120081216: 1532 The afdata and ifnet locks have been changed from mutexes to 1533 rwlocks, network modules will need to be re-compiled. 1534 153520081214: 1536 __FreeBSD_version 800059 incorporates the new arp-v2 rewrite. 1537 RTF_CLONING, RTF_LLINFO and RTF_WASCLONED flags are eliminated. 1538 The new code reduced struct rtentry{} by 16 bytes on 32-bit 1539 architecture and 40 bytes on 64-bit architecture. The userland 1540 applications "arp" and "ndp" have been updated accordingly. 1541 The output from "netstat -r" shows only routing entries and 1542 none of the L2 information. 1543 154420081130: 1545 __FreeBSD_version 800057 marks the switchover from the 1546 binary ath hal to source code. Users must add the line: 1547 1548 options AH_SUPPORT_AR5416 1549 1550 to their kernel config files when specifying: 1551 1552 device ath_hal 1553 1554 The ath_hal module no longer exists; the code is now compiled 1555 together with the driver in the ath module. It is now 1556 possible to tailor chip support (i.e. reduce the set of chips 1557 and thereby the code size); consult ath_hal(4) for details. 1558 155920081121: 1560 __FreeBSD_version 800054 adds memory barriers to 1561 <machine/atomic.h>, new interfaces to ifnet to facilitate 1562 multiple hardware transmit queues for cards that support 1563 them, and a lock-less ring-buffer implementation to 1564 enable drivers to more efficiently manage queueing of 1565 packets. 1566 156720081117: 1568 A new version of ZFS (version 13) has been merged to -HEAD. 1569 This version has zpool attribute "listsnapshots" off by 1570 default, which means "zfs list" does not show snapshots, 1571 and is the same as Solaris behavior. 1572 157320081028: 1574 dummynet(4) ABI has changed. ipfw(8) needs to be recompiled. 1575 157620081009: 1577 The uhci, ohci, ehci and slhci USB Host controller drivers have 1578 been put into separate modules. If you load the usb module 1579 separately through loader.conf you will need to load the 1580 appropriate *hci module as well. E.g. for a UHCI-based USB 2.0 1581 controller add the following to loader.conf: 1582 1583 uhci_load="YES" 1584 ehci_load="YES" 1585 158620081009: 1587 The ABI used by the PMC toolset has changed. Please keep 1588 userland (libpmc(3)) and the kernel module (hwpmc(4)) in 1589 sync. 1590 159120081009: 1592 atapci kernel module now includes only generic PCI ATA 1593 driver. AHCI driver moved to ataahci kernel module. 1594 All vendor-specific code moved into separate kernel modules: 1595 ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, 1596 atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, 1597 atamarvell, atamicron, atanational, atanetcell, atanvidia, 1598 atapromise, ataserverworks, atasiliconimage, atasis, atavia 1599 160020080820: 1601 The TTY subsystem of the kernel has been replaced by a new 1602 implementation, which provides better scalability and an 1603 improved driver model. Most common drivers have been migrated to 1604 the new TTY subsystem, while others have not. The following 1605 drivers have not yet been ported to the new TTY layer: 1606 1607 PCI/ISA: 1608 cy, digi, rc, rp, sio 1609 1610 USB: 1611 ubser, ucycom 1612 1613 Line disciplines: 1614 ng_h4, ng_tty, ppp, sl, snp 1615 1616 Adding these drivers to your kernel configuration file shall 1617 cause compilation to fail. 1618 161920080818: 1620 ntpd has been upgraded to 4.2.4p5. 1621 162220080801: 1623 OpenSSH has been upgraded to 5.1p1. 1624 1625 For many years, FreeBSD's version of OpenSSH preferred DSA 1626 over RSA for host and user authentication keys. With this 1627 upgrade, we've switched to the vendor's default of RSA over 1628 DSA. This may cause upgraded clients to warn about unknown 1629 host keys even for previously known hosts. Users should 1630 follow the usual procedure for verifying host keys before 1631 accepting the RSA key. 1632 1633 This can be circumvented by setting the "HostKeyAlgorithms" 1634 option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh 1635 command line. 1636 1637 Please note that the sequence of keys offered for 1638 authentication has been changed as well. You may want to 1639 specify IdentityFile in a different order to revert this 1640 behavior. 1641 164220080713: 1643 The sio(4) driver has been removed from the i386 and amd64 1644 kernel configuration files. This means uart(4) is now the 1645 default serial port driver on those platforms as well. 1646 1647 To prevent collisions with the sio(4) driver, the uart(4) driver 1648 uses different names for its device nodes. This means the 1649 onboard serial port will now most likely be called "ttyu0" 1650 instead of "ttyd0". You may need to reconfigure applications to 1651 use the new device names. 1652 1653 When using the serial port as a boot console, be sure to update 1654 /boot/device.hints and /etc/ttys before booting the new kernel. 1655 If you forget to do so, you can still manually specify the hints 1656 at the loader prompt: 1657 1658 set hint.uart.0.at="isa" 1659 set hint.uart.0.port="0x3F8" 1660 set hint.uart.0.flags="0x10" 1661 set hint.uart.0.irq="4" 1662 boot -s 1663 166420080609: 1665 The gpt(8) utility has been removed. Use gpart(8) to partition 1666 disks instead. 1667 166820080603: 1669 The version that Linuxulator emulates was changed from 2.4.2 1670 to 2.6.16. If you experience any problems with Linux binaries 1671 please try to set sysctl compat.linux.osrelease to 2.4.2 and 1672 if it fixes the problem contact emulation mailing list. 1673 167420080525: 1675 ISDN4BSD (I4B) was removed from the src tree. You may need to 1676 update a your kernel configuration and remove relevant entries. 1677 167820080509: 1679 I have checked in code to support multiple routing tables. 1680 See the man pages setfib(1) and setfib(2). 1681 This is a hopefully backwards compatible version, 1682 but to make use of it you need to compile your kernel 1683 with options ROUTETABLES=2 (or more up to 16). 1684 168520080420: 1686 The 802.11 wireless support was redone to enable multi-bss 1687 operation on devices that are capable. The underlying device 1688 is no longer used directly but instead wlanX devices are 1689 cloned with ifconfig. This requires changes to rc.conf files. 1690 For example, change: 1691 ifconfig_ath0="WPA DHCP" 1692 to 1693 wlans_ath0=wlan0 1694 ifconfig_wlan0="WPA DHCP" 1695 see rc.conf(5) for more details. In addition, mergemaster of 1696 /etc/rc.d is highly recommended. Simultaneous update of userland 1697 and kernel wouldn't hurt either. 1698 1699 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta 1700 modules were merged into the base wlan module. All references 1701 to these modules (e.g. in kernel config files) must be removed. 1702 170320080408: 1704 psm(4) has gained write(2) support in native operation level. 1705 Arbitrary commands can be written to /dev/psm%d and status can 1706 be read back from it. Therefore, an application is responsible 1707 for status validation and error recovery. It is a no-op in 1708 other operation levels. 1709 171020080312: 1711 Support for KSE threading has been removed from the kernel. To 1712 run legacy applications linked against KSE libmap.conf may 1713 be used. The following libmap.conf may be used to ensure 1714 compatibility with any prior release: 1715 1716 libpthread.so.1 libthr.so.1 1717 libpthread.so.2 libthr.so.2 1718 libkse.so.3 libthr.so.3 1719 172020080301: 1721 The layout of struct vmspace has changed. This affects libkvm 1722 and any executables that link against libkvm and use the 1723 kvm_getprocs() function. In particular, but not exclusively, 1724 it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1). 1725 The effects are minimal, but it's advisable to upgrade world 1726 nonetheless. 1727 172820080229: 1729 The latest em driver no longer has support in it for the 1730 82575 adapter, this is now moved to the igb driver. The 1731 split was done to make new features that are incompatible 1732 with older hardware easier to do. 1733 173420080220: 1735 The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4), 1736 likewise the kernel option is now GEOM_LINUX_LVM. 1737 173820080211: 1739 The default NFS mount mode has changed from UDP to TCP for 1740 increased reliability. If you rely on (insecurely) NFS 1741 mounting across a firewall you may need to update your 1742 firewall rules. 1743 174420080208: 1745 Belatedly note the addition of m_collapse for compacting 1746 mbuf chains. 1747 174820080126: 1749 The fts(3) structures have been changed to use adequate 1750 integer types for their members and so to be able to cope 1751 with huge file trees. The old fts(3) ABI is preserved 1752 through symbol versioning in libc, so third-party binaries 1753 using fts(3) should still work, although they will not take 1754 advantage of the extended types. At the same time, some 1755 third-party software might fail to build after this change 1756 due to unportable assumptions made in its source code about 1757 fts(3) structure members. Such software should be fixed 1758 by its vendor or, in the worst case, in the ports tree. 1759 FreeBSD_version 800015 marks this change for the unlikely 1760 case that a portable fix is impossible. 1761 176220080123: 1763 To upgrade to -current after this date, you must be running 1764 FreeBSD not older than 6.0-RELEASE. Upgrading to -current 1765 from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems. 1766 176720071128: 1768 The ADAPTIVE_GIANT kernel option has been retired because its 1769 functionality is the default now. 1770 177120071118: 1772 The AT keyboard emulation of sunkbd(4) has been turned on 1773 by default. In order to make the special symbols of the Sun 1774 keyboards driven by sunkbd(4) work under X these now have 1775 to be configured the same way as Sun USB keyboards driven 1776 by ukbd(4) (which also does AT keyboard emulation), f.e.: 1777 1778 Option "XkbLayout" "us" 1779 Option "XkbRules" "xorg" 1780 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 1781 178220071024: 1783 It has been decided that it is desirable to provide ABI 1784 backwards compatibility to the FreeBSD 4/5/6 versions of the 1785 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 1786 broken with the introduction of PCI domain support (see the 1787 20070930 entry). Unfortunately, this required the ABI of 1788 PCIOCGETCONF to be broken again in order to be able to 1789 provide backwards compatibility to the old version of that 1790 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 1791 again. As for prominent ports this affects neither pciutils 1792 nor xorg-server this time, the hal port needs to be rebuilt 1793 however. 1794 179520071020: 1796 The misnamed kthread_create() and friends have been renamed 1797 to kproc_create() etc. Many of the callers already 1798 used kproc_start().. 1799 I will return kthread_create() and friends in a while 1800 with implementations that actually create threads, not procs. 1801 Renaming corresponds with version 800002. 1802 180320071010: 1804 RELENG_7 branched. 1805 1806COMMON ITEMS: 1807 1808 General Notes 1809 ------------- 1810 Avoid using make -j when upgrading. While generally safe, there are 1811 sometimes problems using -j to upgrade. If your upgrade fails with 1812 -j, please try again without -j. From time to time in the past there 1813 have been problems using -j with buildworld and/or installworld. This 1814 is especially true when upgrading between "distant" versions (eg one 1815 that cross a major release boundary or several minor releases, or when 1816 several months have passed on the -current branch). 1817 1818 Sometimes, obscure build problems are the result of environment 1819 poisoning. This can happen because the make utility reads its 1820 environment when searching for values for global variables. To run 1821 your build attempts in an "environmental clean room", prefix all make 1822 commands with 'env -i '. See the env(1) manual page for more details. 1823 1824 When upgrading from one major version to another it is generally best 1825 to upgrade to the latest code in the currently installed branch first, 1826 then do an upgrade to the new branch. This is the best-tested upgrade 1827 path, and has the highest probability of being successful. Please try 1828 this approach before reporting problems with a major version upgrade. 1829 1830 ZFS notes 1831 --------- 1832 When upgrading the boot ZFS pool to a new version, always follow 1833 these two steps: 1834 1835 1.) recompile and reinstall the ZFS boot loader and boot block 1836 (this is part of "make buildworld" and "make installworld") 1837 1838 2.) update the ZFS boot block on your boot drive 1839 1840 The following example updates the ZFS boot block on the first 1841 partition (freebsd-boot) of a GPT partitioned drive ad0: 1842 "gpart bootcode -p /boot/gptzfsboot -i 1 ad0" 1843 1844 Non-boot pools do not need these updates. 1845 1846 To build a kernel 1847 ----------------- 1848 If you are updating from a prior version of FreeBSD (even one just 1849 a few days old), you should follow this procedure. It is the most 1850 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1851 1852 make kernel-toolchain 1853 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1854 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1855 1856 To test a kernel once 1857 --------------------- 1858 If you just want to boot a kernel once (because you are not sure 1859 if it works, or if you want to boot a known bad kernel to provide 1860 debugging information) run 1861 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1862 nextboot -k testkernel 1863 1864 To just build a kernel when you know that it won't mess you up 1865 -------------------------------------------------------------- 1866 This assumes you are already running a CURRENT system. Replace 1867 ${arch} with the architecture of your machine (e.g. "i386", 1868 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1869 1870 cd src/sys/${arch}/conf 1871 config KERNEL_NAME_HERE 1872 cd ../compile/KERNEL_NAME_HERE 1873 make depend 1874 make 1875 make install 1876 1877 If this fails, go to the "To build a kernel" section. 1878 1879 To rebuild everything and install it on the current system. 1880 ----------------------------------------------------------- 1881 # Note: sometimes if you are running current you gotta do more than 1882 # is listed here if you are upgrading from a really old current. 1883 1884 <make sure you have good level 0 dumps> 1885 make buildworld 1886 make kernel KERNCONF=YOUR_KERNEL_HERE 1887 [1] 1888 <reboot in single user> [3] 1889 mergemaster -p [5] 1890 make installworld 1891 mergemaster -i [4] 1892 make delete-old [6] 1893 <reboot> 1894 1895 1896 To cross-install current onto a separate partition 1897 -------------------------------------------------- 1898 # In this approach we use a separate partition to hold 1899 # current's root, 'usr', and 'var' directories. A partition 1900 # holding "/", "/usr" and "/var" should be about 2GB in 1901 # size. 1902 1903 <make sure you have good level 0 dumps> 1904 <boot into -stable> 1905 make buildworld 1906 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1907 <maybe newfs current's root partition> 1908 <mount current's root partition on directory ${CURRENT_ROOT}> 1909 make installworld DESTDIR=${CURRENT_ROOT} 1910 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1911 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1912 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1913 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1914 <reboot into current> 1915 <do a "native" rebuild/install as described in the previous section> 1916 <maybe install compatibility libraries from ports/misc/compat*> 1917 <reboot> 1918 1919 1920 To upgrade in-place from stable to current 1921 ---------------------------------------------- 1922 <make sure you have good level 0 dumps> 1923 make buildworld [9] 1924 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1925 [1] 1926 <reboot in single user> [3] 1927 mergemaster -p [5] 1928 make installworld 1929 mergemaster -i [4] 1930 make delete-old [6] 1931 <reboot> 1932 1933 Make sure that you've read the UPDATING file to understand the 1934 tweaks to various things you need. At this point in the life 1935 cycle of current, things change often and you are on your own 1936 to cope. The defaults can also change, so please read ALL of 1937 the UPDATING entries. 1938 1939 Also, if you are tracking -current, you must be subscribed to 1940 freebsd-current@freebsd.org. Make sure that before you update 1941 your sources that you have read and understood all the recent 1942 messages there. If in doubt, please track -stable which has 1943 much fewer pitfalls. 1944 1945 [1] If you have third party modules, such as vmware, you 1946 should disable them at this point so they don't crash your 1947 system on reboot. 1948 1949 [3] From the bootblocks, boot -s, and then do 1950 fsck -p 1951 mount -u / 1952 mount -a 1953 cd src 1954 adjkerntz -i # if CMOS is wall time 1955 Also, when doing a major release upgrade, it is required that 1956 you boot into single user mode to do the installworld. 1957 1958 [4] Note: This step is non-optional. Failure to do this step 1959 can result in a significant reduction in the functionality of the 1960 system. Attempting to do it by hand is not recommended and those 1961 that pursue this avenue should read this file carefully, as well 1962 as the archives of freebsd-current and freebsd-hackers mailing lists 1963 for potential gotchas. The -U option is also useful to consider. 1964 See mergemaster(8) for more information. 1965 1966 [5] Usually this step is a noop. However, from time to time 1967 you may need to do this if you get unknown user in the following 1968 step. It never hurts to do it all the time. You may need to 1969 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1970 install) after the buildworld before this step if you last updated 1971 from [78]-stable or 9-stable before 20130430. 1972 1973 [6] This only deletes old files and directories. Old libraries 1974 can be deleted by "make delete-old-libs", but you have to make 1975 sure that no program is using those libraries anymore. 1976 1977 [8] In order to have a kernel that can run the 4.x binaries needed to 1978 do an installworld, you must include the COMPAT_FREEBSD4 option in 1979 your kernel. Failure to do so may leave you with a system that is 1980 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1981 required to run the 5.x binaries on more recent kernels. And so on 1982 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1983 1984 Make sure that you merge any new devices from GENERIC since the 1985 last time you updated your kernel config file. 1986 1987 [9] When checking out sources, you must include the -P flag to have 1988 cvs prune empty directories. 1989 1990 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1991 "?=" instead of the "=" assignment operator, so that buildworld can 1992 override the CPUTYPE if it needs to. 1993 1994 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1995 not on the command line, or in /etc/make.conf. buildworld will 1996 warn if it is improperly defined. 1997FORMAT: 1998 1999This file contains a list, in reverse chronological order, of major 2000breakages in tracking -current. It is not guaranteed to be a complete 2001list of such breakages, and only contains entries since October 10, 2007. 2002If you need to see UPDATING entries from before that date, you will need 2003to fetch an UPDATING file from an older FreeBSD release. 2004 2005Copyright information: 2006 2007Copyright 1998-2009 M.
