[SA-14:23] 339 34020140916: p2 FreeBSD-SA-14:19.tcp 341 Fix Denial of Service in TCP packet processing. [SA-14:19] 342 34320140909: p1 FreeBSD-SA-14:18.openssl 344 Fix OpenSSL multiple vulnerabilities. [SA-14:18] 345 34620140716: 347 9.3-RELEASE. 348 34920140608: 350 On i386 and amd64 systems, the onifconsole flag is now set by default 351 in /etc/ttys for ttyu0. This causes ttyu0 to be automatically enabled 352 as a login TTY if it is set in the bootloader as an active kernel 353 console. No changes in behavior should result otherwise. To revert to 354 the previous behavior, set ttyu0 to "off" in /etc/ttys. 355 35620140512: 357 Clang and llvm have been upgraded to 3.4.1 release. 358 35920140321: 360 Clang and llvm have been upgraded to 3.4 release. 361 36220140216: 363 The nve(4) driver for NVIDIA nForce MCP Ethernet adapters has 364 been deprecated and will not be part of FreeBSD 11.0 and later 365 releases. If you use this driver, please consider switching to 366 the nfe(4) driver instead. 367 36820131216: 369 The behavior of gss_pseudo_random() for the krb5 mechanism 370 has changed, for applications requesting a longer random string 371 than produced by the underlying enctype's pseudo-random() function. 372 In particular, the random string produced from a session key of 373 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 374 be different at the 17th octet and later, after this change. 375 The counter used in the PRF+ construction is now encoded as a 376 big-endian integer in accordance with RFC 4402. 377 __FreeBSD_version is bumped to 902505. 378 37920130930: 380 9.2-RELEASE. 381 38220130823: 383 Behavior of devfs rules path matching has been changed. 384 Pattern is now always matched against fully qualified devfs 385 path and slash characters must be explicitly matched by 386 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 387 subdirectories must be reviewed. 388 38920130705: 390 hastctl(8)'s `status' command output changed to terse one-liner format. 391 Scripts using this should switch to `list' command or be rewritten. 392 39320130618: 394 Fix a bug that allowed a tracing process (e.g. gdb) to write 395 to a memory-mapped file in the traced process's address space 396 even if neither the traced process nor the tracing process had 397 write access to that file. 398 39920130605: 400 Added ZFS TRIM support which is enabled by default. To disable 401 ZFS TRIM support set vfs.zfs.trim.enabled=0 in loader.conf. 402 403 Creating new ZFS pools and adding new devices to existing pools 404 first performs a full device level TRIM which can take a significant 405 amount of time. The sysctl vfs.zfs.vdev.trim_on_init can be set to 0 406 to disable this behaviour. 407 408 ZFS TRIM requires the underlying device support BIO_DELETE which 409 is currently provided by methods such as ATA TRIM and SCSI UNMAP 410 via CAM, which are typically supported by SSD's. 411 412 Stats for ZFS TRIM can be monitored by looking at the sysctl's 413 under kstat.zfs.misc.zio_trim. 414 41520130524: 416 `list' command has been added to hastctl(8). For now, it is full 417 equivalent of `status' command. 418 WARNING: in the near future the output of hastctl's status command 419 will change to more terse format. If you use `hastctl status' 420 for parsing in your scripts, switch to `hastctl list'. 421 42220130430: 423 The mergemaster command now uses the default MAKEOBJDIRPREFIX 424 rather than creating it's own in the temporary directory in 425 order allow access to bootstrapped versions of tools such as 426 install and mtree. When upgrading from version of FreeBSD where 427 the install command does not support -l, you will need to 428 install a new mergemaster command if mergemaster -p is required. 429 This can be accomplished with the command (cd src/usr.sbin/mergemaster 430 && make install). 431 432 Due to the use of the new -l option to install(1) during build 433 and install, you must take care not to directly set the INSTALL 434 make variable in your /etc/make.conf, /etc/src.conf, or on the 435 command line. If you wish to use the -C flag for all installs 436 you may be able to add INSTALL+=-C to /etc/make.conf or 437 /etc/src.conf. 438 43920130429: 440 Fix a bug that allows NFS clients to issue READDIR on files. 441 44220130315: 443 The install(1) option -M has changed meaning and now takes an 444 argument that is a file or path to append logs to. In the 445 unlikely event that -M was the last option on the command line 446 and the command line contained at least two files and a target 447 directory the first file will have logs appended to it. The -M 448 option served little practical purpose in the last decade so it's 449 used expected to be extremely rare. 450 45120130225: 452 A new compression method (lz4) has been merged to. Please refer to 453 zpool-features(7) for more information. 454 455 Please refer to the "ZFS notes" section of this file for information 456 on upgrading boot ZFS pools. 457 45820121224: 459 The VFS KBI was changed with the merge of several nullfs 460 optimizations and fixes. All filesystem modules must be 461 recompiled. 462 46320121218: 464 With the addition of auditdistd(8), a new auditdistd user is now 465 depended on during installworld. "mergemaster -p" can be used to add 466 the user prior to installworld, as documented in the handbook. 467 46820121205: 469 9.1-RELEASE. 470 47120121129: 472 A new version of ZFS (pool version 5000) has been merged to 9-STABLE. 473 Starting with this version the old system of ZFS pool versioning 474 is superseded by "feature flags". This concept enables forward 475 compatibility against certain future changes in functionality of ZFS 476 pools. The first two read-only compatible "feature flags" for ZFS 477 pools are "com.delphix:async_destroy" and "com.delphix:empty_bpobj". 478 For more information read the new zpool-features(7) manual page. 479 Please refer to the "ZFS notes" section of this file for information 480 on upgrading boot ZFS pools. 481 48220121114: 483 The commit introducing bsd.compiler.mk breaks the traditional 484 building of kernels before this point. Add -m ${SRC}/share/mk 485 (for the right value of SRC) to your command lines to work 486 around; update your useland to a point after this; or use the 487 buildkernel/installkernel top-level targets. See also 20120829. 488 48920121102: 490 The IPFIREWALL_FORWARD kernel option has been removed. Its 491 functionality now turned on by default. 492 49320120913: 494 The random(4) support for the VIA hardware random number 495 generator (`PADLOCK') is no longer enabled unconditionally. 496 Add the PADLOCK_RNG option in the custom kernel config if 497 needed. The GENERIC kernels on i386 and amd64 do include the 498 option, so the change only affects the custom kernel 499 configurations. 500 50120120829: 502 The amd64 kernel now uses xsetbv, xrstor instructions. To compile with 503 the traditional method, you must update your system with an installworld 504 before the kernel will build. The documented make buildkernel/installkernel 505 interfaces (coupled with fresh make kernel-toolchain) continue to work. 506 50720120727: 508 The sparc64 ZFS loader has been changed to no longer try to auto- 509 detect ZFS providers based on diskN aliases but now requires these 510 to be explicitly listed in the OFW boot-device environment variable. 511 51220120422: 513 Now unix domain sockets behave "as expected" on nullfs(5). Previously 514 nullfs(5) did not pass through all behaviours to the underlying layer, 515 as a result if we bound to a socket on the lower layer we could connect 516 only to the lower path; if we bound to the upper layer we could connect 517 only to the upper path. The new behavior is one can connect to both the 518 lower and the upper paths regardless what layer path one binds to. 519 52020120109: 521 The acpi_wmi(4) status device /dev/wmistat has been renamed to 522 /dev/wmistat0. 523 52420120106: 525 A new VOP_ADVISE() was added to support posix_fadvise(2). All 526 filesystem modules must be recompiled. 527 52820120106: 529 The interface of the VOP_VPTOCNP(9) changed, now the returned 530 vnode shall be referenced, previously it was required to be 531 only held. All in-tree filesystems are converted. 532 53320120106: 534 9.0-RELEASE. 535 53620111101: 537 The broken amd(4) driver has been replaced with esp(4) in the amd64, 538 i386 and pc98 GENERIC kernel configuration files. 539 54020110913: 541 This commit modifies vfs_register() so that it uses a hash 542 calculation to set vfc_typenum, which is enabled by default. 543 The first time a system is booted after this change, the 544 vfc_typenum values will change for all file systems. The 545 main effect of this is a change to the NFS server file handles 546 for file systems that use vfc_typenum in their fsid, such as ZFS. 547 It will, however, prevent vfc_typenum from changing when file 548 systems are loaded in a different order for subsequent reboots. 549 To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf 550 until you are ready to remount all NFS clients after a reboot. 551 55220110828: 553 Bump the shared library version numbers for libraries that 554 do not use symbol versioning, have changed the ABI compared 555 to stable/8 and which shared library version was not bumped. 556 Done as part of 9.0-RELEASE cycle. 557 55820110815: 559 During the merge of Capsicum features, the fget(9) KPI was modified. 560 This may require the rebuilding of out-of-tree device drivers -- 561 issues have been reported specifically with the nVidia device driver. 562 __FreeBSD_version is bumped to 900041. 563 564 Also, there is a period between 20110811 and 20110814 where the 565 special devices /dev/{stdin,stdout,stderr} did not work correctly. 566 Building world from a kernel during that window may not work. 567 56820110628: 569 The packet filter (pf) code has been updated to OpenBSD 4.5. 570 You need to update userland tools to be in sync with kernel. 571 This update breaks backward compatibility with earlier pfsync(4) 572 versions. Care must be taken when updating redundant firewall setups. 573 57420110608: 575 The following sysctls and tunables are retired on x86 platforms: 576 machdep.hlt_cpus 577 machdep.hlt_logical_cpus 578 The following sysctl is retired: 579 machdep.hyperthreading_allowed 580 The sysctls were supposed to provide a way to dynamically offline and 581 online selected CPUs on x86 platforms, but the implementation has not 582 been reliable especially with SCHED_ULE scheduler. 583 machdep.hyperthreading_allowed tunable is still available to ignore 584 hyperthreading CPUs at OS level. 585 Individual CPUs can be disabled using hint.lapic.X.disabled tunable, 586 where X is an APIC ID of a CPU. Be advised, though, that disabling 587 CPUs in non-uniform fashion will result in non-uniform topology and 588 may lead to sub-optimal system performance with SCHED_ULE, which is 589 a default scheduler. 590 59120110607: 592 cpumask_t type is retired and cpuset_t is used in order to describe 593 a mask of CPUs. 594 59520110531: 596 Changes to ifconfig(8) for dynamic address family detection mandate 597 that you are running a kernel of 20110525 or later. Make sure to 598 follow the update procedure to boot a new kernel before installing 599 world. 600 60120110513: 602 Support for sun4v architecture is officially dropped 603 60420110503: 605 Several KPI breaking changes have been committed to the mii(4) layer, 606 the PHY drivers and consequently some Ethernet drivers using mii(4). 607 This means that miibus.ko and the modules of the affected Ethernet 608 drivers need to be recompiled. 609 610 Note to kernel developers: Given that the OUI bit reversion problem 611 was fixed as part of these changes all mii(4) commits related to OUIs, 612 i.e. to sys/dev/mii/miidevs, PHY driver probing and vendor specific 613 handling, no longer can be merged verbatim to stable/8 and previous 614 branches. 615 61620110430: 617 Users of the Atheros AR71xx SoC code now need to add 'device ar71xx_pci' 618 into their kernel configurations along with 'device pci'. 619 62020110427: 621 The default NFS client is now the new NFS client, so fstype "newnfs" 622 is now "nfs" and the regular/old NFS client is now fstype "oldnfs". 623 Although mounts via fstype "nfs" will usually work without userland 624 changes, it is recommended that the mount(8) and mount_nfs(8) 625 commands be rebuilt from sources and that a link to mount_nfs called 626 mount_oldnfs be created. The new client is compiled into the 627 kernel with "options NFSCL" and this is needed for diskless root 628 file systems. The GENERIC kernel configs have been changed to use 629 NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER. 630 To use the regular/old client, you can "mount -t oldnfs ...". For 631 a diskless root file system, you must also include a line like: 632 633 vfs.root.mountfrom="oldnfs:" 634 635 in the boot/loader.conf on the root fs on the NFS server to make 636 a diskless root fs use the old client. 637 63820110424: 639 The GENERIC kernels for all architectures now default to the new 640 CAM-based ATA stack. It means that all legacy ATA drivers were 641 removed and replaced by respective CAM drivers. If you are using 642 ATA device names in /etc/fstab or other places, make sure to update 643 them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY, 644 where 'Y's are the sequential numbers starting from zero for each type 645 in order of detection, unless configured otherwise with tunables, 646 see cam(4)). There will be symbolic links created in /dev/ to map 647 old adX devices to the respective adaY. They should provide basic 648 compatibility for file systems mounting in most cases, but they do 649 not support old user-level APIs and do not have respective providers 650 in GEOM. Consider using updated management tools with new device names. 651 652 It is possible to load devices ahci, ata, siis and mvs as modules, 653 but option ATA_CAM should remain in kernel configuration to make ata 654 module work as CAM driver supporting legacy ATA controllers. Device ata 655 still can be used in modular fashion (atacore + ...). Modules atadisk 656 and atapi* are not used and won't affect operation in ATA_CAM mode. 657 Note that to use CAM-based ATA kernel should include CAM devices 658 scbus, pass, da (or explicitly ada), cd and optionally others. All of 659 them are parts of the cam module. 660 661 ataraid(4) functionality is now supported by the RAID GEOM class. 662 To use it you can load geom_raid kernel module and use graid(8) tool 663 for management. Instead of /dev/arX device names, use /dev/raid/rX. 664 665 No kernel config options or code have been removed, so if a problem 666 arises, please report it and optionally revert to the old ATA stack. 667 In order to do it you can remove from the kernel config: 668 options ATA_CAM 669 device ahci 670 device mvs 671 device siis 672 , and instead add back: 673 device atadisk # ATA disk drives 674 device ataraid # ATA RAID drives 675 device atapicd # ATAPI CDROM drives 676 device atapifd # ATAPI floppy drives 677 device atapist # ATAPI tape drives 678 67920110423: 680 The default NFS server has been changed to the new server, which 681 was referred to as the experimental server. If you need to switch 682 back to the old NFS server, you must now put the "-o" option on 683 both the mountd and nfsd commands. This can be done using the 684 mountd_flags and nfs_server_flags rc.conf variables until an 685 update to the rc scripts is committed, which is coming soon. 686 68720110418: 688 The GNU Objective-C runtime library (libobjc), and other Objective-C 689 related components have been removed from the base system. If you 690 require an Objective-C library, please use one of the available ports. 691 69220110331: 693 ath(4) has been split into bus- and device- modules. if_ath contains 694 the HAL, the TX rate control and the network device code. if_ath_pci 695 contains the PCI bus glue. For Atheros MIPS embedded systems, if_ath_ahb 696 contains the AHB glue. Users need to load both if_ath_pci and if_ath 697 in order to use ath on everything else. 698 699 TO REPEAT: if_ath_ahb is not needed for normal users. Normal users only 700 need to load if_ath and if_ath_pci for ath(4) operation. 701 70220110314: 703 As part of the replacement of sysinstall, the process of building 704 release media has changed significantly. For details, please re-read 705 release(7), which has been updated to reflect the new build process. 706 70720110218: 708 GNU binutils 2.17.50 (as of 2007-07-03) has been merged to -HEAD. This 709 is the last available version under GPLv2. It brings a number of new 710 features, such as support for newer x86 CPU's (with SSE-3, SSSE-3, SSE 711 4.1 and SSE 4.2), better support for powerpc64, a number of new 712 directives, and lots of other small improvements. See the ChangeLog 713 file in contrib/binutils for the full details. 714 71520110218: 716 IPsec's HMAC_SHA256-512 support has been fixed to be RFC4868 717 compliant, and will now use half of hash for authentication. 718 This will break interoperability with all stacks (including all 719 actual FreeBSD versions) who implement 720 draft-ietf-ipsec-ciph-sha-256-00 (they use 96 bits of hash for 721 authentication). 722 The only workaround with such peers is to use another HMAC 723 algorithm for IPsec ("phase 2") authentication. 724 72520110207: 726 Remove the uio_yield prototype and symbol. This function has 727 been misnamed since it was introduced and should not be 728 globally exposed with this name. The equivalent functionality 729 is now available using kern_yield(curthread->td_user_pri). 730 The function remains undocumented. 731 73220110112: 733 A SYSCTL_[ADD_]UQUAD was added for unsigned uint64_t pointers, 734 symmetric with the existing SYSCTL_[ADD_]QUAD. Type checking 735 for scalar sysctls is defined but disabled. Code that needs 736 UQUAD to pass the type checking that must compile on older 737 systems where the define is not present can check against 738 __FreeBSD_version >= 900030. 739 740 The system dialog(1) has been replaced with a new version previously 741 in ports as devel/cdialog. dialog(1) is mostly command-line compatible 742 with the previous version, but the libdialog associated with it has 743 a largely incompatible API. As such, the original version of libdialog 744 will be kept temporarily as libodialog, until its base system consumers 745 are replaced or updated. Bump __FreeBSD_version to 900030. 746 74720110103: 748 If you are trying to run make universe on a -stable system, and you get 749 the following warning: 750 "Makefile", line 356: "Target architecture for i386/conf/GENERIC 751 unknown. config(8) likely too old." 752 or something similar to it, then you must upgrade your -stable system 753 to 8.2-Release or newer (really, any time after r210146 7/15/2010 in 754 stable/8) or build the config from the latest stable/8 branch and 755 install it on your system. 756 757 Prior to this date, building a current universe on 8-stable system from 758 between 7/15/2010 and 1/2/2011 would result in a weird shell parsing 759 error in the first kernel build phase. A new config on those old 760 systems will fix that problem for older versions of -current. 761 76220101228: 763 The TCP stack has been modified to allow Khelp modules to interact with 764 it via helper hook points and store per-connection data in the TCP 765 control block. Bump __FreeBSD_version to 900029. User space tools that 766 rely on the size of struct tcpcb in tcp_var.h (e.g. sockstat) need to 767 be recompiled. 768 76920101114: 770 Generic IEEE 802.3 annex 31B full duplex flow control support has been 771 added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along 772 with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted 773 to take advantage of it instead of using custom implementations. This 774 means that these drivers now no longer unconditionally advertise 775 support for flow control but only do so if flow control is a selected 776 media option. This was implemented in the generic support that way in 777 order to allow flow control to be switched on and off via ifconfig(8) 778 with the PHY specific default to typically off in order to protect 779 from unwanted effects. Consequently, if you used flow control with 780 one of the above mentioned drivers you now need to explicitly enable 781 it, for example via: 782 ifconfig bge0 media auto mediaopt flowcontrol 783 784 Along with the above mentioned changes generic support for setting 785 1000baseT master mode also has been added and brgphy(4), ciphy(4), 786 e1000phy(4) as well as ip1000phy(4) have been converted to take 787 advantage of it. This means that these drivers now no longer take the 788 link0 parameter for selecting master mode but the master media option 789 has to be used instead, for example like in the following: 790 ifconfig bge0 media 1000baseT mediaopt full-duplex,master 791 792 Selection of master mode now is also available with all other PHY 793 drivers supporting 1000baseT. 794 79520101111: 796 The TCP stack has received a significant update to add support for 797 modularised congestion control and generally improve the clarity of 798 congestion control decisions. Bump __FreeBSD_version to 900025. User 799 space tools that rely on the size of struct tcpcb in tcp_var.h (e.g. 800 sockstat) need to be recompiled. 801 80220101002: 803 The man(1) utility has been replaced by a new version that no longer 804 uses /etc/manpath.config. Please consult man.conf(5) for how to 805 migrate local entries to the new format. 806 80720100928: 808 The copyright strings printed by login(1) and sshd(8) at the time of a 809 new connection have been removed to follow other operating systems and 810 upstream sshd. 811 81220100915: 813 A workaround for a fixed ld bug has been removed in kernel code, 814 so make sure that your system ld is built from sources after 815 revision 210245 from 2010-07-19 (r211583 if building head kernel 816 on stable/8, r211584 for stable/7; both from 2010-08-21). 817 A symptom of incorrect ld version is different addresses for 818 set_pcpu section and __start_set_pcpu symbol in kernel and/or modules. 819 82020100913: 821 The $ipv6_prefer variable in rc.conf(5) has been split into 822 $ip6addrctl_policy and $ipv6_activate_all_interfaces. 823 824 The $ip6addrctl_policy is a variable to choose a pre-defined 825 address selection policy set by ip6addrctl(8). A value 826 "ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The 827 default is "AUTO". 828 829 The $ipv6_activate_all_interfaces specifies whether IFDISABLED 830 flag (see an entry of 20090926) is set on an interface with no 831 corresponding $ifconfig_IF_ipv6 line. The default is "NO" for 832 security reason. If you want IPv6 link-local address on all 833 interfaces by default, set this to "YES". 834 835 The old ipv6_prefer="YES" is equivalent to 836 ipv6_activate_all_interfaces="YES" and 837 ip6addrctl_policy="ipv6_prefer". 838 83920100913: 840 DTrace has grown support for userland tracing. Due to this, DTrace is 841 now i386 and amd64 only. 842 dtruss(1) is now installed by default on those systems and a new 843 kernel module is needed for userland tracing: fasttrap. 844 No changes to your kernel config file are necessary to enable 845 userland tracing, but you might consider adding 'STRIP=' and 846 'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want 847 to have informative userland stack traces in DTrace (ustack). 848 84920100725: 850 The acpi_aiboost(4) driver has been removed in favor of the new 851 aibs(4) driver. You should update your kernel configuration file. 852 85320100722: 854 BSD grep has been imported to the base system and it is built by 855 default. It is completely BSD licensed, highly GNU-compatible, uses 856 less memory than its GNU counterpart and has a small codebase. 857 However, it is slower than its GNU counterpart, which is mostly 858 noticeable for larger searches, for smaller ones it is measurable 859 but not significant. The reason is complex, the most important factor 860 is that we lack a modern and efficient regex library and GNU 861 overcomes this by optimizing the searches internally. Future work 862 on improving the regex performance is planned, for the meantime, 863 users that need better performance, can build GNU grep instead by 864 setting the WITH_GNU_GREP knob. 865 86620100713: 867 Due to the import of powerpc64 support, all existing powerpc kernel 868 configuration files must be updated with a machine directive like this: 869 machine powerpc powerpc 870 871 In addition, an updated config(8) is required to build powerpc kernels 872 after this change. 873 87420100713: 875 A new version of ZFS (version 15) has been merged to -HEAD. 876 This version uses a python library for the following subcommands: 877 zfs allow, zfs unallow, zfs groupspace, zfs userspace. 878 For full functionality of these commands the following port must 879 be installed: sysutils/py-zfs 880 88120100429: 882 'vm_page's are now hashed by physical address to an array of mutexes. 883 Currently this is only used to serialize access to hold_count. Over 884 time the page queue mutex will be peeled away. This changes the size 885 of pmap on every architecture. And requires all callers of vm_page_hold 886 and vm_page_unhold to be updated. 887 88820100402: 889 WITH_CTF can now be specified in src.conf (not recommended, there 890 are some problems with static executables), make.conf (would also 891 affect ports which do not use GNU make and do not override the 892 compile targets) or in the kernel config (via "makeoptions 893 WITH_CTF=yes"). 894 When WITH_CTF was specified there before this was silently ignored, 895 so make sure that WITH_CTF is not used in places which could lead 896 to unwanted behavior. 897 89820100311: 899 The kernel option COMPAT_IA32 has been replaced with COMPAT_FREEBSD32 900 to allow 32-bit compatibility on non-x86 platforms. All kernel 901 configurations on amd64 and ia64 platforms using these options must 902 be modified accordingly. 903 90420100113: 905 The utmp user accounting database has been replaced with utmpx, 906 the user accounting interface standardized by POSIX. 907 Unfortunately the semantics of utmp and utmpx don't match, 908 making it practically impossible to support both interfaces. 909 The user accounting database is used by tools like finger(1), 910 last(1), talk(1), w(1) and ac(8). 911 912 All applications in the base system use utmpx. This means only 913 local binaries (e.g. from the ports tree) may still use these 914 utmp database files. These applications must be rebuilt to make 915 use of utmpx. 916 917 After the system has been upgraded, it is safe to remove the old 918 log files (/var/run/utmp, /var/log/lastlog and /var/log/wtmp*), 919 assuming their contents is of no importance anymore. Old wtmp 920 databases can only be used by last(1) and ac(8) after they have 921 been converted to the new format using wtmpcvt(1). 922 92320100108: 924 Introduce the kernel thread "deadlock resolver" (which can be enabled 925 via the DEADLKRES option, see NOTES for more details) and the 926 sleepq_type() function for sleepqueues. 927 92820091202: 929 The rc.firewall and rc.firewall6 were unified, and 930 rc.firewall6 and rc.d/ip6fw were removed. 931 According to the removal of rc.d/ip6fw, ipv6_firewall_* rc 932 variables are obsoleted. Instead, the following new rc 933 variables are added to rc.d/ipfw: 934 935 firewall_client_net_ipv6, firewall_simple_iif_ipv6, 936 firewall_simple_inet_ipv6, firewall_simple_oif_ipv6, 937 firewall_simple_onet_ipv6, firewall_trusted_ipv6 938 939 The meanings correspond to the relevant IPv4 variables. 940 94120091125: 942 8.0-RELEASE. 943 94420091113: 945 The default terminal emulation for syscons(4) has been changed 946 from cons25 to xterm on all platforms except pc98. This means 947 that the /etc/ttys file needs to be updated to ensure correct 948 operation of applications on the console. 949 950 The terminal emulation style can be toggled per window by using 951 vidcontrol(1)'s -T flag. The TEKEN_CONS25 kernel configuration 952 options can be used to change the compile-time default back to 953 cons25. 954 955 To prevent graphical artifacts, make sure the TERM environment 956 variable is set to match the terminal emulation that is being 957 performed by syscons(4). 958 95920091109: 960 The layout of the structure ieee80211req_scan_result has changed. 961 Applications that require wireless scan results (e.g. ifconfig(8)) 962 from net80211 need to be recompiled. 963 964 Applications such as wpa_supplicant(8) may require a full world 965 build without using NO_CLEAN in order to get synchronized with the 966 new structure. 967 96820091025: 969 The iwn(4) driver has been updated to support the 5000 and 5150 series. 970 There's one kernel module for each firmware. Adding "device iwnfw" 971 to the kernel configuration file means including all three firmware 972 images inside the kernel. If you want to include just the one for 973 your wireless card, use the devices iwn4965fw, iwn5000fw or 974 iwn5150fw. 975 97620090926: 977 The rc.d/network_ipv6, IPv6 configuration script has been integrated 978 into rc.d/netif. The changes are the following: 979 980 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF 981 for IPv4. For aliases, $ifconfig_IF_aliasN should be used. 982 Note that both variables need the "inet6" keyword at the head. 983 984 Do not set $ipv6_network_interfaces manually if you do not 985 understand what you are doing. It is not needed in most cases. 986 987 $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but 988 they are obsolete. 989 990 2. $ipv6_enable is obsolete. Use $ipv6_prefer and 991 "inet6 accept_rtadv" keyword in ifconfig(8) instead. 992 993 If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and 994 all configured interfaces have "inet6 accept_rtadv" in the 995 $ifconfig_IF_ipv6. These are for backward compatibility. 996 997 3. A new variable $ipv6_prefer has been added. If NO, IPv6 998 functionality of interfaces with no corresponding 999 $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag, 1000 and the default address selection policy of ip6addrctl(8) 1001 is the IPv4-preferred one (see rc.d/ip6addrctl for more details). 1002 Note that if you want to configure IPv6 functionality on the 1003 disabled interfaces after boot, first you need to clear the flag by 1004 using ifconfig(8) like: 1005 1006 ifconfig em0 inet6 -ifdisabled 1007 1008 If YES, the default address selection policy is set as 1009 IPv6-preferred. 1010 1011 The default value of $ipv6_prefer is NO. 1012 1013 4. If your system need to receive Router Advertisement messages, 1014 define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8) 1015 scripts automatically invoke rtsol(8) when the interface becomes 1016 UP. The Router Advertisement messages are used for SLAAC 1017 (State-Less Address AutoConfiguration). 1018 101920090922: 1020 802.11s D3.03 support was committed. This is incompatible with the 1021 previous code, which was based on D3.0. 1022 102320090912: 1024 A sysctl variable net.inet6.ip6.accept_rtadv now sets the default value 1025 of a per-interface flag ND6_IFF_ACCEPT_RTADV, not a global knob to 1026 control whether accepting Router Advertisement messages or not. 1027 Also, a per-interface flag ND6_IFF_AUTO_LINKLOCAL has been added and 1028 a sysctl variable net.inet6.ip6.auto_linklocal is its default value. 1029 The ifconfig(8) utility now supports these flags. 1030 103120090910: 1032 ZFS snapshots are now mounted with MNT_IGNORE flag. Use -v option for 1033 mount(8) and -a option for df(1) to see them. 1034 103520090825: 1036 The old tunable hw.bus.devctl_disable has been superseded by 1037 hw.bus.devctl_queue. hw.bus.devctl_disable=1 in loader.conf should be 1038 replaced by hw.bus.devctl_queue=0. The default for this new tunable 1039 is 1000. 1040 104120090813: 1042 Remove the option STOP_NMI. The default action is now to use NMI only 1043 for KDB via the newly introduced function stop_cpus_hard() and 1044 maintain stop_cpus() to just use a normal IPI_STOP on ia32 and amd64. 1045 104620090803: 1047 The stable/8 branch created in subversion. This corresponds to the 1048 RELENG_8 branch in CVS. 1049 105020090719: 1051 Bump the shared library version numbers for all libraries that do not 1052 use symbol versioning as part of the 8.0-RELEASE cycle. Bump 1053 __FreeBSD_version to 800105. 1054 105520090714: 1056 Due to changes in the implementation of virtual network stack support, 1057 all network-related kernel modules must be recompiled. As this change 1058 breaks the ABI, bump __FreeBSD_version to 800104. 1059 106020090713: 1061 The TOE interface to the TCP syncache has been modified to remove 1062 struct tcpopt (<netinet/tcp_var.h>) from the ABI of the network stack. 1063 The cxgb driver is the only TOE consumer affected by this change, and 1064 needs to be recompiled along with the kernel. As this change breaks 1065 the ABI, bump __FreeBSD_version to 800103. 1066 106720090712: 1068 Padding has been added to struct tcpcb, sackhint and tcpstat in 1069 <netinet/tcp_var.h> to facilitate future MFCs and bug fixes whilst 1070 maintaining the ABI. However, this change breaks the ABI, so bump 1071 __FreeBSD_version to 800102. User space tools that rely on the size of 1072 any of these structs (e.g. sockstat) need to be recompiled. 1073 107420090630: 1075 The NFS_LEGACYRPC option has been removed along with the old kernel 1076 RPC implementation that this option selected. Kernel configurations 1077 may need to be adjusted. 1078 107920090629: 1080 The network interface device nodes at /dev/net/<interface> have been 1081 removed. All ioctl operations can be performed the normal way using 1082 routing sockets. The kqueue functionality can generally be replaced 1083 with routing sockets. 1084 108520090628: 1086 The documentation from the FreeBSD Documentation Project (Handbook, 1087 FAQ, etc.) is now installed via packages by sysinstall(8) and under 1088 the /usr/local/share/doc/freebsd directory instead of /usr/share/doc. 1089 109020090624: 1091 The ABI of various structures related to the SYSV IPC API have been 1092 changed. As a result, the COMPAT_FREEBSD[456] and COMPAT_43 kernel 1093 options now all require COMPAT_FREEBSD7. Bump __FreeBSD_version to 1094 800100. 1095 109620090622: 1097 Layout of struct vnet has changed as routing related variables were 1098 moved to their own Vimage module. Modules need to be recompiled. Bump 1099 __FreeBSD_version to 800099. 1100 110120090619: 1102 NGROUPS_MAX and NGROUPS have been increased from 16 to 1023 and 1024 1103 respectively. As long as no more than 16 groups per process are used, 1104 no changes should be visible. When more than 16 groups are used, old 1105 binaries may fail if they call getgroups() or getgrouplist() with 1106 statically sized storage. Recompiling will work around this, but 1107 applications should be modified to use dynamically allocated storage 1108 for group arrays as POSIX.1-2008 does not cap an implementation's 1109 number of supported groups at NGROUPS_MAX+1 as previous versions did. 1110 1111 NFS and portalfs mounts may also be affected as the list of groups is 1112 truncated to 16. Users of NFS who use more than 16 groups, should 1113 take care that negative group permissions are not used on the exported 1114 file systems as they will not be reliable unless a GSSAPI based 1115 authentication method is used. 1116 111720090616: 1118 The compiling option ADAPTIVE_LOCKMGRS has been introduced. This 1119 option compiles in the support for adaptive spinning for lockmgrs 1120 which want to enable it. The lockinit() function now accepts the flag 1121 LK_ADAPTIVE in order to make the lock object subject to adaptive 1122 spinning when both held in write and read mode. 1123 112420090613: 1125 The layout of the structure returned by IEEE80211_IOC_STA_INFO has 1126 changed. User applications that use this ioctl need to be rebuilt. 1127 112820090611: 1129 The layout of struct thread has changed. Kernel and modules need to 1130 be rebuilt. 1131 113220090608: 1133 The layout of structs ifnet, domain, protosw and vnet_net has changed. 1134 Kernel modules need to be rebuilt. Bump __FreeBSD_version to 800097. 1135 113620090602: 1137 window(1) has been removed from the base system. It can now be 1138 installed from ports. The port is called misc/window. 1139 114020090601: 1141 The way we are storing and accessing `routing table' entries has 1142 changed. Programs reading the FIB, like netstat, need to be 1143 re-compiled. 1144 114520090601: 1146 A new netisr implementation has been added for FreeBSD 8. Network 1147 file system modules, such as igmp, ipdivert, and others, should be 1148 rebuilt. 1149 Bump __FreeBSD_version to 800096. 1150 115120090530: 1152 Remove the tunable/sysctl debug.mpsafevfs as its initial purpose is no 1153 more valid. 1154 115520090530: 1156 Add VOP_ACCESSX(9). File system modules need to be rebuilt. 1157 Bump __FreeBSD_version to 800094. 1158 115920090529: 1160 Add mnt_xflag field to 'struct mount'. File system modules need to be 1161 rebuilt. 1162 Bump __FreeBSD_version to 800093. 1163 116420090528: 1165 The compiling option ADAPTIVE_SX has been retired while it has been 1166 introduced the option NO_ADAPTIVE_SX which handles the reversed logic. 1167 The KPI for sx_init_flags() changes as accepting flags: 1168 SX_ADAPTIVESPIN flag has been retired while the SX_NOADAPTIVE flag has 1169 been introduced in order to handle the reversed logic. 1170 Bump __FreeBSD_version to 800092. 1171 117220090527: 1173 Add support for hierarchical jails. Remove global securelevel. 1174 Bump __FreeBSD_version to 800091. 1175 117620090523: 1177 The layout of struct vnet_net has changed, therefore modules 1178 need to be rebuilt. 1179 Bump __FreeBSD_version to 800090. 1180 118120090523: 1182 The newly imported zic(8) produces a new format in the output. Please 1183 run tzsetup(8) to install the newly created data to /etc/localtime. 1184 118520090520: 1186 The sysctl tree for the usb stack has renamed from hw.usb2.* to 1187 hw.usb.* and is now consistent again with previous releases. 1188 118920090520: 1190 802.11 monitor mode support was revised and driver api's were changed. 1191 Drivers dependent on net80211 now support DLT_IEEE802_11_RADIO instead 1192 of DLT_IEEE802_11. No user-visible data structures were changed but 1193 applications that use DLT_IEEE802_11 may require changes. 1194 Bump __FreeBSD_version to 800088. 1195 119620090430: 1197 The layout of the following structs has changed: sysctl_oid, 1198 socket, ifnet, inpcbinfo, tcpcb, syncache_head, vnet_inet, 1199 vnet_inet6 and vnet_ipfw. Most modules need to be rebuild or 1200 panics may be experienced. World rebuild is required for 1201 correctly checking networking state from userland. 1202 Bump __FreeBSD_version to 800085. 1203 120420090429: 1205 MLDv2 and Source-Specific Multicast (SSM) have been merged 1206 to the IPv6 stack. VIMAGE hooks are in but not yet used. 1207 The implementation of SSM within FreeBSD's IPv6 stack closely 1208 follows the IPv4 implementation. 1209 1210 For kernel developers: 1211 1212 * The most important changes are that the ip6_output() and 1213 ip6_input() paths no longer take the IN6_MULTI_LOCK, 1214 and this lock has been downgraded to a non-recursive mutex. 1215 1216 * As with the changes to the IPv4 stack to support SSM, filtering 1217 of inbound multicast traffic must now be performed by transport 1218 protocols within the IPv6 stack. This does not apply to TCP and 1219 SCTP, however, it does apply to UDP in IPv6 and raw IPv6. 1220 1221 * The KPIs used by IPv6 multicast are similar to those used by 1222 the IPv4 stack, with the following differences: 1223 * im6o_mc_filter() is analogous to imo_multicast_filter(). 1224 * The legacy KAME entry points in6_joingroup and in6_leavegroup() 1225 are shimmed to in6_mc_join() and in6_mc_leave() respectively. 1226 * IN6_LOOKUP_MULTI() has been deprecated and removed. 1227 * IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs 1228 for MLDv1 have an additional 'timer' argument which is used to 1229 jitter the initial membership report for the solicited-node 1230 multicast membership on-link. 1231 * This is not strictly needed for MLDv2, which already jitters 1232 its report transmissions. However, the 'timer' argument is 1233 preserved in case MLDv1 is active on the interface. 1234 1235 * The KAME linked-list based IPv6 membership implementation has 1236 been refactored to use a vector similar to that used by the IPv4 1237 stack. 1238 Code which maintains a list of its own multicast memberships 1239 internally, e.g. carp, has been updated to reflect the new 1240 semantics. 1241 1242 * There is a known Lock Order Reversal (LOR) due to in6_setscope() 1243 acquiring the IF_AFDATA_LOCK and being called within ip6_output(). 1244 Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an 1245 implementation constraint which needs to be addressed in HEAD. 1246 1247 For application developers: 1248 1249 * The changes are broadly similar to those made for the IPv4 1250 stack. 1251 1252 * The use of IPv4 and IPv6 multicast socket options on the same 1253 socket, using mapped addresses, HAS NOT been tested or supported. 1254 1255 * There are a number of issues with the implementation of various 1256 IPv6 multicast APIs which need to be resolved in the API surface 1257 before the implementation is fully compatible with KAME userland 1258 use, and these are mostly to do with interface index treatment. 1259 1260 * The literature available discusses the use of either the delta / ASM 1261 API with setsockopt(2)/getsockopt(2), or the full-state / ASM API 1262 using setsourcefilter(3)/getsourcefilter(3). For more information 1263 please refer to RFC 3768, 'Socket Interface Extensions for 1264 Multicast Source Filters'. 1265 1266 * Applications which use the published RFC 3678 APIs should be fine. 1267 1268 For systems administrators: 1269 1270 * The mtest(8) utility has been refactored to support IPv6, in 1271 addition to IPv4. Interface addresses are no longer accepted 1272 as arguments, their names must be used instead. The utility 1273 will map the interface name to its first IPv4 address as 1274 returned by getifaddrs(3). 1275 1276 * The ifmcstat(8) utility has also been updated to print the MLDv2 1277 endpoint state and source filter lists via sysctl(3). 1278 1279 * The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable 1280 loopback of IPv6 multicast datagrams by default; it defaults to 1 1281 to preserve the existing behaviour. Disabling multicast loopback is 1282 recommended for optimal system performance. 1283 1284 * The IPv6 MROUTING code has been changed to examine this sysctl 1285 instead of attempting to perform a group lookup before looping 1286 back forwarded datagrams. 1287 1288 Bump __FreeBSD_version to 800084. 1289 129020090422: 1291 Implement low-level Bluetooth HCI API. 1292 Bump __FreeBSD_version to 800083. 1293 129420090419: 1295 The layout of struct malloc_type, used by modules to register new 1296 memory allocation types, has changed. Most modules will need to 1297 be rebuilt or panics may be experienced. 1298 Bump __FreeBSD_version to 800081. 1299 130020090415: 1301 Anticipate overflowing inp_flags - add inp_flags2. 1302 This changes most offsets in inpcb, so checking v4 connection 1303 state will require a world rebuild. 1304 Bump __FreeBSD_version to 800080. 1305 130620090415: 1307 Add an llentry to struct route and struct route_in6. Modules 1308 embedding a struct route will need to be recompiled. 1309 Bump __FreeBSD_version to 800079. 1310 131120090414: 1312 The size of rt_metrics_lite and by extension rtentry has changed. 1313 Networking administration apps will need to be recompiled. 1314 The route command now supports show as an alias for get, weighting 1315 of routes, sticky and nostick flags to alter the behavior of stateful 1316 load balancing. 1317 Bump __FreeBSD_version to 800078. 1318 131920090408: 1320 Do not use Giant for kbdmux(4) locking. This is wrong and 1321 apparently causing more problems than it solves. This will 1322 re-open the issue where interrupt handlers may race with 1323 kbdmux(4) in polling mode. Typical symptoms include (but 1324 not limited to) duplicated and/or missing characters when 1325 low level console functions (such as gets) are used while 1326 interrupts are enabled (for example geli password prompt, 1327 mountroot prompt etc.). Disabling kbdmux(4) may help. 1328 132920090407: 1330 The size of structs vnet_net, vnet_inet and vnet_ipfw has changed; 1331 kernel modules referencing any of the above need to be recompiled. 1332 Bump __FreeBSD_version to 800075. 1333 133420090320: 1335 GEOM_PART has become the default partition slicer for storage devices, 1336 replacing GEOM_MBR, GEOM_BSD, GEOM_PC98 and GEOM_GPT slicers. It 1337 introduces some changes: 1338 1339 MSDOS/EBR: the devices created from MSDOS extended partition entries 1340 (EBR) can be named differently than with GEOM_MBR and are now symlinks 1341 to devices with offset-based names. fstabs may need to be modified. 1342 1343 BSD: the "geometry does not match label" warning is harmless in most 1344 cases but it points to problems in file system misalignment with 1345 disk geometry. The "c" partition is now implicit, covers the whole 1346 top-level drive and cannot be (mis)used by users. 1347 1348 General: Kernel dumps are now not allowed to be written to devices 1349 whose partition types indicate they are meant to be used for file 1350 systems (or, in case of MSDOS partitions, as something else than 1351 the "386BSD" type). 1352 1353 Most of these changes date approximately from 200812. 1354 135520090319: 1356 The uscanner(4) driver has been removed from the kernel. This follows 1357 Linux removing theirs in 2.6 and making libusb the default interface 1358 (supported by sane). 1359 136020090319: 1361 The multicast forwarding code has been cleaned up. netstat(1) 1362 only relies on KVM now for printing bandwidth upcall meters. 1363 The IPv4 and IPv6 modules are split into ip_mroute_mod and 1364 ip6_mroute_mod respectively. The config(5) options for statically 1365 compiling this code remain the same, i.e. 'options MROUTING'. 1366 136720090315: 1368 Support for the IFF_NEEDSGIANT network interface flag has been 1369 removed, which means that non-MPSAFE network device drivers are no 1370 longer supported. In particular, if_ar, if_sr, and network device 1371 drivers from the old (legacy) USB stack can no longer be built or 1372 used. 1373 137420090313: 1375 POSIX.1 Native Language Support (NLS) has been enabled in libc and 1376 a bunch of new language catalog files have also been added. 1377 This means that some common libc messages are now localized and 1378 they depend on the LC_MESSAGES environmental variable. 1379 138020090313: 1381 The k8temp(4) driver has been renamed to amdtemp(4) since 1382 support for Family 10 and Family 11 CPU families was added. 1383 138420090309: 1385 IGMPv3 and Source-Specific Multicast (SSM) have been merged 1386 to the IPv4 stack. VIMAGE hooks are in but not yet used. 1387 1388 For kernel developers, the most important changes are that the 1389 ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(), 1390 and this lock has been downgraded to a non-recursive mutex. 1391 1392 Transport protocols (UDP, Raw IP) are now responsible for filtering 1393 inbound multicast traffic according to group membership and source 1394 filters. The imo_multicast_filter() KPI exists for this purpose. 1395 Transports which do not use multicast (SCTP, TCP) already reject 1396 multicast by default. Forwarding and receive performance may improve 1397 as a mutex acquisition is no longer needed in the ip_input() 1398 low-level input path. in_addmulti() and in_delmulti() are shimmed 1399 to new KPIs which exist to support SSM in-kernel. 1400 1401 For application developers, it is recommended that loopback of 1402 multicast datagrams be disabled for best performance, as this 1403 will still cause the lock to be taken for each looped-back 1404 datagram transmission. The net.inet.ip.mcast.loop sysctl may 1405 be tuned to 0 to disable loopback by default; it defaults to 1 1406 to preserve the existing behaviour. 1407 1408 For systems administrators, to obtain best performance with 1409 multicast reception and multiple groups, it is always recommended 1410 that a card with a suitably precise hash filter is used. Hash 1411 collisions will still result in the lock being taken within the 1412 transport protocol input path to check group membership. 1413 1414 If deploying FreeBSD in an environment with IGMP snooping switches, 1415 it is recommended that the net.inet.igmp.sendlocal sysctl remain 1416 enabled; this forces 224.0.0.0/24 group membership to be announced 1417 via IGMP. 1418 1419 The size of 'struct igmpstat' has changed; netstat needs to be 1420 recompiled to reflect this. 1421 Bump __FreeBSD_version to 800070. 1422 142320090309: 1424 libusb20.so.1 is now installed as libusb.so.1 and the ports system 1425 updated to use it. This requires a buildworld/installworld in order to 1426 update the library and dependencies (usbconfig, etc). Its advisable to 1427 rebuild all ports which uses libusb. More specific directions are given 1428 in the ports collection UPDATING file. Any /etc/libmap.conf entries for 1429 libusb are no longer required and can be removed. 1430 143120090302: 1432 A workaround is committed to allow the creation of System V shared 1433 memory segment of size > 2 GB on the 64-bit architectures. 1434 Due to a limitation of the existing ABI, the shm_segsz member 1435 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is 1436 wrong for large segments. Note that limits must be explicitly 1437 raised to allow such segments to be created. 1438 143920090301: 1440 The layout of struct ifnet has changed, requiring a rebuild of all 1441 network device driver modules. 1442 144320090227: 1444 The /dev handling for the new USB stack has changed, a 1445 buildworld/installworld is required for libusb20. 1446 144720090223: 1448 The new USB2 stack has now been permanently moved in and all kernel and 1449 module names reverted to their previous values (eg, usb, ehci, ohci, 1450 ums, ...). The old usb stack can be compiled in by prefixing the name 1451 with the letter 'o', the old usb modules have been removed. 1452 Updating entry 20090216 for xorg and 20090215 for libmap may still 1453 apply. 1454 145520090217: 1456 The rc.conf(5) option if_up_delay has been renamed to 1457 defaultroute_delay to better reflect its purpose. If you have 1458 customized this setting in /etc/rc.conf you need to update it to 1459 use the new name. 1460 146120090216: 1462 xorg 7.4 wants to configure its input devices via hald which does not 1463 yet work with USB2. If the keyboard/mouse does not work in xorg then 1464 add 1465 Option "AllowEmptyInput" "off" 1466 to your ServerLayout section. This will cause X to use the configured 1467 kbd and mouse sections from your xorg.conf. 1468 146920090215: 1470 The GENERIC kernels for all architectures now default to the new USB2 1471 stack. No kernel config options or code have been removed so if a 1472 problem arises please report it and optionally revert to the old USB 1473 stack. If you are loading USB kernel modules or have a custom kernel 1474 that includes GENERIC then ensure that usb names are also changed over, 1475 eg uftdi -> usb2_serial_ftdi. 1476 1477 Older programs linked against the ports libusb 0.1 need to be 1478 redirected to the new stack's libusb20. /etc/libmap.conf can 1479 be used for this: 1480 # Map old usb library to new one for usb2 stack 1481 libusb-0.1.so.8 libusb20.so.1 1482 148320090209: 1484 All USB ethernet devices now attach as interfaces under the name ueN 1485 (eg. ue0). This is to provide a predictable name as vendors often 1486 change usb chipsets in a product without notice. 1487 148820090203: 1489 The ichsmb(4) driver has been changed to require SMBus slave 1490 addresses be left-justified (xxxxxxx0b) rather than right-justified. 1491 All of the other SMBus controller drivers require left-justified 1492 slave addresses, so this change makes all the drivers provide the 1493 same interface. 1494 149520090201: 1496 INET6 statistics (struct ip6stat) was updated. 1497 netstat(1) needs to be recompiled. 1498 149920090119: 1500 NTFS has been removed from GENERIC kernel on amd64 to match 1501 GENERIC on i386. Should not cause any issues since mount_ntfs(8) 1502 will load ntfs.ko module automatically when NTFS support is 1503 actually needed, unless ntfs.ko is not installed or security 1504 level prohibits loading kernel modules. If either is the case, 1505 "options NTFS" has to be added into kernel config. 1506 150720090115: 1508 TCP Appropriate Byte Counting (RFC 3465) support added to kernel. 1509 New field in struct tcpcb breaks ABI, so bump __FreeBSD_version to 1510 800061. User space tools that rely on the size of struct tcpcb in 1511 tcp_var.h (e.g. sockstat) need to be recompiled. 1512 151320081225: 1514 ng_tty(4) module updated to match the new TTY subsystem. 1515 Due to API change, user-level applications must be updated. 1516 New API support added to mpd5 CVS and expected to be present 1517 in next mpd5.3 release. 1518 151920081219: 1520 With __FreeBSD_version 800060 the makefs tool is part of 1521 the base system (it was a port). 1522 152320081216: 1524 The afdata and ifnet locks have been changed from mutexes to 1525 rwlocks, network modules will need to be re-compiled. 1526 152720081214: 1528 __FreeBSD_version 800059 incorporates the new arp-v2 rewrite. 1529 RTF_CLONING, RTF_LLINFO and RTF_WASCLONED flags are eliminated. 1530 The new code reduced struct rtentry{} by 16 bytes on 32-bit 1531 architecture and 40 bytes on 64-bit architecture. The userland 1532 applications "arp" and "ndp" have been updated accordingly. 1533 The output from "netstat -r" shows only routing entries and 1534 none of the L2 information. 1535 153620081130: 1537 __FreeBSD_version 800057 marks the switchover from the 1538 binary ath hal to source code. Users must add the line: 1539 1540 options AH_SUPPORT_AR5416 1541 1542 to their kernel config files when specifying: 1543 1544 device ath_hal 1545 1546 The ath_hal module no longer exists; the code is now compiled 1547 together with the driver in the ath module. It is now 1548 possible to tailor chip support (i.e. reduce the set of chips 1549 and thereby the code size); consult ath_hal(4) for details. 1550 155120081121: 1552 __FreeBSD_version 800054 adds memory barriers to 1553 <machine/atomic.h>, new interfaces to ifnet to facilitate 1554 multiple hardware transmit queues for cards that support 1555 them, and a lock-less ring-buffer implementation to 1556 enable drivers to more efficiently manage queueing of 1557 packets. 1558 155920081117: 1560 A new version of ZFS (version 13) has been merged to -HEAD. 1561 This version has zpool attribute "listsnapshots" off by 1562 default, which means "zfs list" does not show snapshots, 1563 and is the same as Solaris behavior. 1564 156520081028: 1566 dummynet(4) ABI has changed. ipfw(8) needs to be recompiled. 1567 156820081009: 1569 The uhci, ohci, ehci and slhci USB Host controller drivers have 1570 been put into separate modules. If you load the usb module 1571 separately through loader.conf you will need to load the 1572 appropriate *hci module as well. E.g. for a UHCI-based USB 2.0 1573 controller add the following to loader.conf: 1574 1575 uhci_load="YES" 1576 ehci_load="YES" 1577 157820081009: 1579 The ABI used by the PMC toolset has changed. Please keep 1580 userland (libpmc(3)) and the kernel module (hwpmc(4)) in 1581 sync. 1582 158320081009: 1584 atapci kernel module now includes only generic PCI ATA 1585 driver. AHCI driver moved to ataahci kernel module. 1586 All vendor-specific code moved into separate kernel modules: 1587 ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, 1588 atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, 1589 atamarvell, atamicron, atanational, atanetcell, atanvidia, 1590 atapromise, ataserverworks, atasiliconimage, atasis, atavia 1591 159220080820: 1593 The TTY subsystem of the kernel has been replaced by a new 1594 implementation, which provides better scalability and an 1595 improved driver model. Most common drivers have been migrated to 1596 the new TTY subsystem, while others have not. The following 1597 drivers have not yet been ported to the new TTY layer: 1598 1599 PCI/ISA: 1600 cy, digi, rc, rp, sio 1601 1602 USB: 1603 ubser, ucycom 1604 1605 Line disciplines: 1606 ng_h4, ng_tty, ppp, sl, snp 1607 1608 Adding these drivers to your kernel configuration file shall 1609 cause compilation to fail. 1610 161120080818: 1612 ntpd has been upgraded to 4.2.4p5. 1613 161420080801: 1615 OpenSSH has been upgraded to 5.1p1. 1616 1617 For many years, FreeBSD's version of OpenSSH preferred DSA 1618 over RSA for host and user authentication keys. With this 1619 upgrade, we've switched to the vendor's default of RSA over 1620 DSA. This may cause upgraded clients to warn about unknown 1621 host keys even for previously known hosts. Users should 1622 follow the usual procedure for verifying host keys before 1623 accepting the RSA key. 1624 1625 This can be circumvented by setting the "HostKeyAlgorithms" 1626 option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh 1627 command line. 1628 1629 Please note that the sequence of keys offered for 1630 authentication has been changed as well. You may want to 1631 specify IdentityFile in a different order to revert this 1632 behavior. 1633 163420080713: 1635 The sio(4) driver has been removed from the i386 and amd64 1636 kernel configuration files. This means uart(4) is now the 1637 default serial port driver on those platforms as well. 1638 1639 To prevent collisions with the sio(4) driver, the uart(4) driver 1640 uses different names for its device nodes. This means the 1641 onboard serial port will now most likely be called "ttyu0" 1642 instead of "ttyd0". You may need to reconfigure applications to 1643 use the new device names. 1644 1645 When using the serial port as a boot console, be sure to update 1646 /boot/device.hints and /etc/ttys before booting the new kernel. 1647 If you forget to do so, you can still manually specify the hints 1648 at the loader prompt: 1649 1650 set hint.uart.0.at="isa" 1651 set hint.uart.0.port="0x3F8" 1652 set hint.uart.0.flags="0x10" 1653 set hint.uart.0.irq="4" 1654 boot -s 1655 165620080609: 1657 The gpt(8) utility has been removed. Use gpart(8) to partition 1658 disks instead. 1659 166020080603: 1661 The version that Linuxulator emulates was changed from 2.4.2 1662 to 2.6.16. If you experience any problems with Linux binaries 1663 please try to set sysctl compat.linux.osrelease to 2.4.2 and 1664 if it fixes the problem contact emulation mailing list. 1665 166620080525: 1667 ISDN4BSD (I4B) was removed from the src tree. You may need to 1668 update a your kernel configuration and remove relevant entries. 1669 167020080509: 1671 I have checked in code to support multiple routing tables. 1672 See the man pages setfib(1) and setfib(2). 1673 This is a hopefully backwards compatible version, 1674 but to make use of it you need to compile your kernel 1675 with options ROUTETABLES=2 (or more up to 16). 1676 167720080420: 1678 The 802.11 wireless support was redone to enable multi-bss 1679 operation on devices that are capable. The underlying device 1680 is no longer used directly but instead wlanX devices are 1681 cloned with ifconfig. This requires changes to rc.conf files. 1682 For example, change: 1683 ifconfig_ath0="WPA DHCP" 1684 to 1685 wlans_ath0=wlan0 1686 ifconfig_wlan0="WPA DHCP" 1687 see rc.conf(5) for more details. In addition, mergemaster of 1688 /etc/rc.d is highly recommended. Simultaneous update of userland 1689 and kernel wouldn't hurt either. 1690 1691 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta 1692 modules were merged into the base wlan module. All references 1693 to these modules (e.g. in kernel config files) must be removed. 1694 169520080408: 1696 psm(4) has gained write(2) support in native operation level. 1697 Arbitrary commands can be written to /dev/psm%d and status can 1698 be read back from it. Therefore, an application is responsible 1699 for status validation and error recovery. It is a no-op in 1700 other operation levels. 1701 170220080312: 1703 Support for KSE threading has been removed from the kernel. To 1704 run legacy applications linked against KSE libmap.conf may 1705 be used. The following libmap.conf may be used to ensure 1706 compatibility with any prior release: 1707 1708 libpthread.so.1 libthr.so.1 1709 libpthread.so.2 libthr.so.2 1710 libkse.so.3 libthr.so.3 1711 171220080301: 1713 The layout of struct vmspace has changed. This affects libkvm 1714 and any executables that link against libkvm and use the 1715 kvm_getprocs() function. In particular, but not exclusively, 1716 it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1). 1717 The effects are minimal, but it's advisable to upgrade world 1718 nonetheless. 1719 172020080229: 1721 The latest em driver no longer has support in it for the 1722 82575 adapter, this is now moved to the igb driver. The 1723 split was done to make new features that are incompatible 1724 with older hardware easier to do. 1725 172620080220: 1727 The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4), 1728 likewise the kernel option is now GEOM_LINUX_LVM. 1729 173020080211: 1731 The default NFS mount mode has changed from UDP to TCP for 1732 increased reliability. If you rely on (insecurely) NFS 1733 mounting across a firewall you may need to update your 1734 firewall rules. 1735 173620080208: 1737 Belatedly note the addition of m_collapse for compacting 1738 mbuf chains. 1739 174020080126: 1741 The fts(3) structures have been changed to use adequate 1742 integer types for their members and so to be able to cope 1743 with huge file trees. The old fts(3) ABI is preserved 1744 through symbol versioning in libc, so third-party binaries 1745 using fts(3) should still work, although they will not take 1746 advantage of the extended types. At the same time, some 1747 third-party software might fail to build after this change 1748 due to unportable assumptions made in its source code about 1749 fts(3) structure members. Such software should be fixed 1750 by its vendor or, in the worst case, in the ports tree. 1751 FreeBSD_version 800015 marks this change for the unlikely 1752 case that a portable fix is impossible. 1753 175420080123: 1755 To upgrade to -current after this date, you must be running 1756 FreeBSD not older than 6.0-RELEASE. Upgrading to -current 1757 from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems. 1758 175920071128: 1760 The ADAPTIVE_GIANT kernel option has been retired because its 1761 functionality is the default now. 1762 176320071118: 1764 The AT keyboard emulation of sunkbd(4) has been turned on 1765 by default. In order to make the special symbols of the Sun 1766 keyboards driven by sunkbd(4) work under X these now have 1767 to be configured the same way as Sun USB keyboards driven 1768 by ukbd(4) (which also does AT keyboard emulation), f.e.: 1769 1770 Option "XkbLayout" "us" 1771 Option "XkbRules" "xorg" 1772 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 1773 177420071024: 1775 It has been decided that it is desirable to provide ABI 1776 backwards compatibility to the FreeBSD 4/5/6 versions of the 1777 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 1778 broken with the introduction of PCI domain support (see the 1779 20070930 entry). Unfortunately, this required the ABI of 1780 PCIOCGETCONF to be broken again in order to be able to 1781 provide backwards compatibility to the old version of that 1782 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 1783 again. As for prominent ports this affects neither pciutils 1784 nor xorg-server this time, the hal port needs to be rebuilt 1785 however. 1786 178720071020: 1788 The misnamed kthread_create() and friends have been renamed 1789 to kproc_create() etc. Many of the callers already 1790 used kproc_start().. 1791 I will return kthread_create() and friends in a while 1792 with implementations that actually create threads, not procs. 1793 Renaming corresponds with version 800002. 1794 179520071010: 1796 RELENG_7 branched. 1797 1798COMMON ITEMS: 1799 1800 General Notes 1801 ------------- 1802 Avoid using make -j when upgrading. While generally safe, there are 1803 sometimes problems using -j to upgrade. If your upgrade fails with 1804 -j, please try again without -j. From time to time in the past there 1805 have been problems using -j with buildworld and/or installworld. This 1806 is especially true when upgrading between "distant" versions (eg one 1807 that cross a major release boundary or several minor releases, or when 1808 several months have passed on the -current branch). 1809 1810 Sometimes, obscure build problems are the result of environment 1811 poisoning. This can happen because the make utility reads its 1812 environment when searching for values for global variables. To run 1813 your build attempts in an "environmental clean room", prefix all make 1814 commands with 'env -i '. See the env(1) manual page for more details. 1815 1816 When upgrading from one major version to another it is generally best 1817 to upgrade to the latest code in the currently installed branch first, 1818 then do an upgrade to the new branch. This is the best-tested upgrade 1819 path, and has the highest probability of being successful. Please try 1820 this approach before reporting problems with a major version upgrade. 1821 1822 ZFS notes 1823 --------- 1824 When upgrading the boot ZFS pool to a new version, always follow 1825 these two steps: 1826 1827 1.) recompile and reinstall the ZFS boot loader and boot block 1828 (this is part of "make buildworld" and "make installworld") 1829 1830 2.) update the ZFS boot block on your boot drive 1831 1832 The following example updates the ZFS boot block on the first 1833 partition (freebsd-boot) of a GPT partitioned drive ad0: 1834 "gpart bootcode -p /boot/gptzfsboot -i 1 ad0" 1835 1836 Non-boot pools do not need these updates. 1837 1838 To build a kernel 1839 ----------------- 1840 If you are updating from a prior version of FreeBSD (even one just 1841 a few days old), you should follow this procedure. It is the most 1842 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1843 1844 make kernel-toolchain 1845 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1846 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1847 1848 To test a kernel once 1849 --------------------- 1850 If you just want to boot a kernel once (because you are not sure 1851 if it works, or if you want to boot a known bad kernel to provide 1852 debugging information) run 1853 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1854 nextboot -k testkernel 1855 1856 To just build a kernel when you know that it won't mess you up 1857 -------------------------------------------------------------- 1858 This assumes you are already running a CURRENT system. Replace 1859 ${arch} with the architecture of your machine (e.g. "i386", 1860 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1861 1862 cd src/sys/${arch}/conf 1863 config KERNEL_NAME_HERE 1864 cd ../compile/KERNEL_NAME_HERE 1865 make depend 1866 make 1867 make install 1868 1869 If this fails, go to the "To build a kernel" section. 1870 1871 To rebuild everything and install it on the current system. 1872 ----------------------------------------------------------- 1873 # Note: sometimes if you are running current you gotta do more than 1874 # is listed here if you are upgrading from a really old current. 1875 1876 <make sure you have good level 0 dumps> 1877 make buildworld 1878 make kernel KERNCONF=YOUR_KERNEL_HERE 1879 [1] 1880 <reboot in single user> [3] 1881 mergemaster -p [5] 1882 make installworld 1883 mergemaster -i [4] 1884 make delete-old [6] 1885 <reboot> 1886 1887 1888 To cross-install current onto a separate partition 1889 -------------------------------------------------- 1890 # In this approach we use a separate partition to hold 1891 # current's root, 'usr', and 'var' directories. A partition 1892 # holding "/", "/usr" and "/var" should be about 2GB in 1893 # size. 1894 1895 <make sure you have good level 0 dumps> 1896 <boot into -stable> 1897 make buildworld 1898 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1899 <maybe newfs current's root partition> 1900 <mount current's root partition on directory ${CURRENT_ROOT}> 1901 make installworld DESTDIR=${CURRENT_ROOT} 1902 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1903 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1904 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1905 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1906 <reboot into current> 1907 <do a "native" rebuild/install as described in the previous section> 1908 <maybe install compatibility libraries from ports/misc/compat*> 1909 <reboot> 1910 1911 1912 To upgrade in-place from stable to current 1913 ---------------------------------------------- 1914 <make sure you have good level 0 dumps> 1915 make buildworld [9] 1916 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1917 [1] 1918 <reboot in single user> [3] 1919 mergemaster -p [5] 1920 make installworld 1921 mergemaster -i [4] 1922 make delete-old [6] 1923 <reboot> 1924 1925 Make sure that you've read the UPDATING file to understand the 1926 tweaks to various things you need. At this point in the life 1927 cycle of current, things change often and you are on your own 1928 to cope. The defaults can also change, so please read ALL of 1929 the UPDATING entries. 1930 1931 Also, if you are tracking -current, you must be subscribed to 1932 freebsd-current@freebsd.org. Make sure that before you update 1933 your sources that you have read and understood all the recent 1934 messages there. If in doubt, please track -stable which has 1935 much fewer pitfalls. 1936 1937 [1] If you have third party modules, such as vmware, you 1938 should disable them at this point so they don't crash your 1939 system on reboot. 1940 1941 [3] From the bootblocks, boot -s, and then do 1942 fsck -p 1943 mount -u / 1944 mount -a 1945 cd src 1946 adjkerntz -i # if CMOS is wall time 1947 Also, when doing a major release upgrade, it is required that 1948 you boot into single user mode to do the installworld. 1949 1950 [4] Note: This step is non-optional. Failure to do this step 1951 can result in a significant reduction in the functionality of the 1952 system. Attempting to do it by hand is not recommended and those 1953 that pursue this avenue should read this file carefully, as well 1954 as the archives of freebsd-current and freebsd-hackers mailing lists 1955 for potential gotchas. The -U option is also useful to consider. 1956 See mergemaster(8) for more information. 1957 1958 [5] Usually this step is a noop. However, from time to time 1959 you may need to do this if you get unknown user in the following 1960 step. It never hurts to do it all the time. You may need to 1961 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1962 install) after the buildworld before this step if you last updated 1963 from [78]-stable or 9-stable before 20130430. 1964 1965 [6] This only deletes old files and directories. Old libraries 1966 can be deleted by "make delete-old-libs", but you have to make 1967 sure that no program is using those libraries anymore. 1968 1969 [8] In order to have a kernel that can run the 4.x binaries needed to 1970 do an installworld, you must include the COMPAT_FREEBSD4 option in 1971 your kernel. Failure to do so may leave you with a system that is 1972 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1973 required to run the 5.x binaries on more recent kernels. And so on 1974 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1975 1976 Make sure that you merge any new devices from GENERIC since the 1977 last time you updated your kernel config file. 1978 1979 [9] When checking out sources, you must include the -P flag to have 1980 cvs prune empty directories. 1981 1982 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1983 "?=" instead of the "=" assignment operator, so that buildworld can 1984 override the CPUTYPE if it needs to. 1985 1986 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1987 not on the command line, or in /etc/make.conf. buildworld will 1988 warn if it is improperly defined. 1989FORMAT: 1990 1991This file contains a list, in reverse chronological order, of major 1992breakages in tracking -current. It is not guaranteed to be a complete 1993list of such breakages, and only contains entries since October 10, 2007. 1994If you need to see UPDATING entries from before that date, you will need 1995to fetch an UPDATING file from an older FreeBSD release. 1996 1997Copyright information: 1998 1999Copyright 1998-2009 M.
