[SA-14:19] 209 21020140909: p1 FreeBSD-SA-14:18.openssl 211 Fix OpenSSL multiple vulnerabilities. [SA-14:18] 212 21320140716: 214 9.3-RELEASE. 215 21620140608: 217 On i386 and amd64 systems, the onifconsole flag is now set by default 218 in /etc/ttys for ttyu0. This causes ttyu0 to be automatically enabled 219 as a login TTY if it is set in the bootloader as an active kernel 220 console. No changes in behavior should result otherwise. To revert to 221 the previous behavior, set ttyu0 to "off" in /etc/ttys. 222 22320140512: 224 Clang and llvm have been upgraded to 3.4.1 release. 225 22620140321: 227 Clang and llvm have been upgraded to 3.4 release. 228 22920140216: 230 The nve(4) driver for NVIDIA nForce MCP Ethernet adapters has 231 been deprecated and will not be part of FreeBSD 11.0 and later 232 releases. If you use this driver, please consider switching to 233 the nfe(4) driver instead. 234 23520131216: 236 The behavior of gss_pseudo_random() for the krb5 mechanism 237 has changed, for applications requesting a longer random string 238 than produced by the underlying enctype's pseudo-random() function. 239 In particular, the random string produced from a session key of 240 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 241 be different at the 17th octet and later, after this change. 242 The counter used in the PRF+ construction is now encoded as a 243 big-endian integer in accordance with RFC 4402. 244 __FreeBSD_version is bumped to 902505. 245 24620130930: 247 9.2-RELEASE. 248 24920130823: 250 Behavior of devfs rules path matching has been changed. 251 Pattern is now always matched against fully qualified devfs 252 path and slash characters must be explicitly matched by 253 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 254 subdirectories must be reviewed. 255 25620130705: 257 hastctl(8)'s `status' command output changed to terse one-liner format. 258 Scripts using this should switch to `list' command or be rewritten. 259 26020130618: 261 Fix a bug that allowed a tracing process (e.g. gdb) to write 262 to a memory-mapped file in the traced process's address space 263 even if neither the traced process nor the tracing process had 264 write access to that file. 265 26620130605: 267 Added ZFS TRIM support which is enabled by default. To disable 268 ZFS TRIM support set vfs.zfs.trim.enabled=0 in loader.conf. 269 270 Creating new ZFS pools and adding new devices to existing pools 271 first performs a full device level TRIM which can take a significant 272 amount of time. The sysctl vfs.zfs.vdev.trim_on_init can be set to 0 273 to disable this behaviour. 274 275 ZFS TRIM requires the underlying device support BIO_DELETE which 276 is currently provided by methods such as ATA TRIM and SCSI UNMAP 277 via CAM, which are typically supported by SSD's. 278 279 Stats for ZFS TRIM can be monitored by looking at the sysctl's 280 under kstat.zfs.misc.zio_trim. 281 28220130524: 283 `list' command has been added to hastctl(8). For now, it is full 284 equivalent of `status' command. 285 WARNING: in the near future the output of hastctl's status command 286 will change to more terse format. If you use `hastctl status' 287 for parsing in your scripts, switch to `hastctl list'. 288 28920130430: 290 The mergemaster command now uses the default MAKEOBJDIRPREFIX 291 rather than creating it's own in the temporary directory in 292 order allow access to bootstrapped versions of tools such as 293 install and mtree. When upgrading from version of FreeBSD where 294 the install command does not support -l, you will need to 295 install a new mergemaster command if mergemaster -p is required. 296 This can be accomplished with the command (cd src/usr.sbin/mergemaster 297 && make install). 298 299 Due to the use of the new -l option to install(1) during build 300 and install, you must take care not to directly set the INSTALL 301 make variable in your /etc/make.conf, /etc/src.conf, or on the 302 command line. If you wish to use the -C flag for all installs 303 you may be able to add INSTALL+=-C to /etc/make.conf or 304 /etc/src.conf. 305 30620130429: 307 Fix a bug that allows NFS clients to issue READDIR on files. 308 30920130315: 310 The install(1) option -M has changed meaning and now takes an 311 argument that is a file or path to append logs to. In the 312 unlikely event that -M was the last option on the command line 313 and the command line contained at least two files and a target 314 directory the first file will have logs appended to it. The -M 315 option served little practical purpose in the last decade so it's 316 used expected to be extremely rare. 317 31820130225: 319 A new compression method (lz4) has been merged to. Please refer to 320 zpool-features(7) for more information. 321 322 Please refer to the "ZFS notes" section of this file for information 323 on upgrading boot ZFS pools. 324 32520121224: 326 The VFS KBI was changed with the merge of several nullfs 327 optimizations and fixes. All filesystem modules must be 328 recompiled. 329 33020121218: 331 With the addition of auditdistd(8), a new auditdistd user is now 332 depended on during installworld. "mergemaster -p" can be used to add 333 the user prior to installworld, as documented in the handbook. 334 33520121205: 336 9.1-RELEASE. 337 33820121129: 339 A new version of ZFS (pool version 5000) has been merged to 9-STABLE. 340 Starting with this version the old system of ZFS pool versioning 341 is superseded by "feature flags". This concept enables forward 342 compatibility against certain future changes in functionality of ZFS 343 pools. The first two read-only compatible "feature flags" for ZFS 344 pools are "com.delphix:async_destroy" and "com.delphix:empty_bpobj". 345 For more information read the new zpool-features(7) manual page. 346 Please refer to the "ZFS notes" section of this file for information 347 on upgrading boot ZFS pools. 348 34920121114: 350 The commit introducing bsd.compiler.mk breaks the traditional 351 building of kernels before this point. Add -m ${SRC}/share/mk 352 (for the right value of SRC) to your command lines to work 353 around; update your useland to a point after this; or use the 354 buildkernel/installkernel top-level targets. See also 20120829. 355 35620121102: 357 The IPFIREWALL_FORWARD kernel option has been removed. Its 358 functionality now turned on by default. 359 36020120913: 361 The random(4) support for the VIA hardware random number 362 generator (`PADLOCK') is no longer enabled unconditionally. 363 Add the PADLOCK_RNG option in the custom kernel config if 364 needed. The GENERIC kernels on i386 and amd64 do include the 365 option, so the change only affects the custom kernel 366 configurations. 367 36820120829: 369 The amd64 kernel now uses xsetbv, xrstor instructions. To compile with 370 the traditional method, you must update your system with an installworld 371 before the kernel will build. The documented make buildkernel/installkernel 372 interfaces (coupled with fresh make kernel-toolchain) continue to work. 373 37420120727: 375 The sparc64 ZFS loader has been changed to no longer try to auto- 376 detect ZFS providers based on diskN aliases but now requires these 377 to be explicitly listed in the OFW boot-device environment variable. 378 37920120422: 380 Now unix domain sockets behave "as expected" on nullfs(5). Previously 381 nullfs(5) did not pass through all behaviours to the underlying layer, 382 as a result if we bound to a socket on the lower layer we could connect 383 only to the lower path; if we bound to the upper layer we could connect 384 only to the upper path. The new behavior is one can connect to both the 385 lower and the upper paths regardless what layer path one binds to. 386 38720120109: 388 The acpi_wmi(4) status device /dev/wmistat has been renamed to 389 /dev/wmistat0. 390 39120120106: 392 A new VOP_ADVISE() was added to support posix_fadvise(2). All 393 filesystem modules must be recompiled. 394 39520120106: 396 The interface of the VOP_VPTOCNP(9) changed, now the returned 397 vnode shall be referenced, previously it was required to be 398 only held. All in-tree filesystems are converted. 399 40020120106: 401 9.0-RELEASE. 402 40320111101: 404 The broken amd(4) driver has been replaced with esp(4) in the amd64, 405 i386 and pc98 GENERIC kernel configuration files. 406 40720110913: 408 This commit modifies vfs_register() so that it uses a hash 409 calculation to set vfc_typenum, which is enabled by default. 410 The first time a system is booted after this change, the 411 vfc_typenum values will change for all file systems. The 412 main effect of this is a change to the NFS server file handles 413 for file systems that use vfc_typenum in their fsid, such as ZFS. 414 It will, however, prevent vfc_typenum from changing when file 415 systems are loaded in a different order for subsequent reboots. 416 To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf 417 until you are ready to remount all NFS clients after a reboot. 418 41920110828: 420 Bump the shared library version numbers for libraries that 421 do not use symbol versioning, have changed the ABI compared 422 to stable/8 and which shared library version was not bumped. 423 Done as part of 9.0-RELEASE cycle. 424 42520110815: 426 During the merge of Capsicum features, the fget(9) KPI was modified. 427 This may require the rebuilding of out-of-tree device drivers -- 428 issues have been reported specifically with the nVidia device driver. 429 __FreeBSD_version is bumped to 900041. 430 431 Also, there is a period between 20110811 and 20110814 where the 432 special devices /dev/{stdin,stdout,stderr} did not work correctly. 433 Building world from a kernel during that window may not work. 434 43520110628: 436 The packet filter (pf) code has been updated to OpenBSD 4.5. 437 You need to update userland tools to be in sync with kernel. 438 This update breaks backward compatibility with earlier pfsync(4) 439 versions. Care must be taken when updating redundant firewall setups. 440 44120110608: 442 The following sysctls and tunables are retired on x86 platforms: 443 machdep.hlt_cpus 444 machdep.hlt_logical_cpus 445 The following sysctl is retired: 446 machdep.hyperthreading_allowed 447 The sysctls were supposed to provide a way to dynamically offline and 448 online selected CPUs on x86 platforms, but the implementation has not 449 been reliable especially with SCHED_ULE scheduler. 450 machdep.hyperthreading_allowed tunable is still available to ignore 451 hyperthreading CPUs at OS level. 452 Individual CPUs can be disabled using hint.lapic.X.disabled tunable, 453 where X is an APIC ID of a CPU. Be advised, though, that disabling 454 CPUs in non-uniform fashion will result in non-uniform topology and 455 may lead to sub-optimal system performance with SCHED_ULE, which is 456 a default scheduler. 457 45820110607: 459 cpumask_t type is retired and cpuset_t is used in order to describe 460 a mask of CPUs. 461 46220110531: 463 Changes to ifconfig(8) for dynamic address family detection mandate 464 that you are running a kernel of 20110525 or later. Make sure to 465 follow the update procedure to boot a new kernel before installing 466 world. 467 46820110513: 469 Support for sun4v architecture is officially dropped 470 47120110503: 472 Several KPI breaking changes have been committed to the mii(4) layer, 473 the PHY drivers and consequently some Ethernet drivers using mii(4). 474 This means that miibus.ko and the modules of the affected Ethernet 475 drivers need to be recompiled. 476 477 Note to kernel developers: Given that the OUI bit reversion problem 478 was fixed as part of these changes all mii(4) commits related to OUIs, 479 i.e. to sys/dev/mii/miidevs, PHY driver probing and vendor specific 480 handling, no longer can be merged verbatim to stable/8 and previous 481 branches. 482 48320110430: 484 Users of the Atheros AR71xx SoC code now need to add 'device ar71xx_pci' 485 into their kernel configurations along with 'device pci'. 486 48720110427: 488 The default NFS client is now the new NFS client, so fstype "newnfs" 489 is now "nfs" and the regular/old NFS client is now fstype "oldnfs". 490 Although mounts via fstype "nfs" will usually work without userland 491 changes, it is recommended that the mount(8) and mount_nfs(8) 492 commands be rebuilt from sources and that a link to mount_nfs called 493 mount_oldnfs be created. The new client is compiled into the 494 kernel with "options NFSCL" and this is needed for diskless root 495 file systems. The GENERIC kernel configs have been changed to use 496 NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER. 497 To use the regular/old client, you can "mount -t oldnfs ...". For 498 a diskless root file system, you must also include a line like: 499 500 vfs.root.mountfrom="oldnfs:" 501 502 in the boot/loader.conf on the root fs on the NFS server to make 503 a diskless root fs use the old client. 504 50520110424: 506 The GENERIC kernels for all architectures now default to the new 507 CAM-based ATA stack. It means that all legacy ATA drivers were 508 removed and replaced by respective CAM drivers. If you are using 509 ATA device names in /etc/fstab or other places, make sure to update 510 them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY, 511 where 'Y's are the sequential numbers starting from zero for each type 512 in order of detection, unless configured otherwise with tunables, 513 see cam(4)). There will be symbolic links created in /dev/ to map 514 old adX devices to the respective adaY. They should provide basic 515 compatibility for file systems mounting in most cases, but they do 516 not support old user-level APIs and do not have respective providers 517 in GEOM. Consider using updated management tools with new device names. 518 519 It is possible to load devices ahci, ata, siis and mvs as modules, 520 but option ATA_CAM should remain in kernel configuration to make ata 521 module work as CAM driver supporting legacy ATA controllers. Device ata 522 still can be used in modular fashion (atacore + ...). Modules atadisk 523 and atapi* are not used and won't affect operation in ATA_CAM mode. 524 Note that to use CAM-based ATA kernel should include CAM devices 525 scbus, pass, da (or explicitly ada), cd and optionally others. All of 526 them are parts of the cam module. 527 528 ataraid(4) functionality is now supported by the RAID GEOM class. 529 To use it you can load geom_raid kernel module and use graid(8) tool 530 for management. Instead of /dev/arX device names, use /dev/raid/rX. 531 532 No kernel config options or code have been removed, so if a problem 533 arises, please report it and optionally revert to the old ATA stack. 534 In order to do it you can remove from the kernel config: 535 options ATA_CAM 536 device ahci 537 device mvs 538 device siis 539 , and instead add back: 540 device atadisk # ATA disk drives 541 device ataraid # ATA RAID drives 542 device atapicd # ATAPI CDROM drives 543 device atapifd # ATAPI floppy drives 544 device atapist # ATAPI tape drives 545 54620110423: 547 The default NFS server has been changed to the new server, which 548 was referred to as the experimental server. If you need to switch 549 back to the old NFS server, you must now put the "-o" option on 550 both the mountd and nfsd commands. This can be done using the 551 mountd_flags and nfs_server_flags rc.conf variables until an 552 update to the rc scripts is committed, which is coming soon. 553 55420110418: 555 The GNU Objective-C runtime library (libobjc), and other Objective-C 556 related components have been removed from the base system. If you 557 require an Objective-C library, please use one of the available ports. 558 55920110331: 560 ath(4) has been split into bus- and device- modules. if_ath contains 561 the HAL, the TX rate control and the network device code. if_ath_pci 562 contains the PCI bus glue. For Atheros MIPS embedded systems, if_ath_ahb 563 contains the AHB glue. Users need to load both if_ath_pci and if_ath 564 in order to use ath on everything else. 565 566 TO REPEAT: if_ath_ahb is not needed for normal users. Normal users only 567 need to load if_ath and if_ath_pci for ath(4) operation. 568 56920110314: 570 As part of the replacement of sysinstall, the process of building 571 release media has changed significantly. For details, please re-read 572 release(7), which has been updated to reflect the new build process. 573 57420110218: 575 GNU binutils 2.17.50 (as of 2007-07-03) has been merged to -HEAD. This 576 is the last available version under GPLv2. It brings a number of new 577 features, such as support for newer x86 CPU's (with SSE-3, SSSE-3, SSE 578 4.1 and SSE 4.2), better support for powerpc64, a number of new 579 directives, and lots of other small improvements. See the ChangeLog 580 file in contrib/binutils for the full details. 581 58220110218: 583 IPsec's HMAC_SHA256-512 support has been fixed to be RFC4868 584 compliant, and will now use half of hash for authentication. 585 This will break interoperability with all stacks (including all 586 actual FreeBSD versions) who implement 587 draft-ietf-ipsec-ciph-sha-256-00 (they use 96 bits of hash for 588 authentication). 589 The only workaround with such peers is to use another HMAC 590 algorithm for IPsec ("phase 2") authentication. 591 59220110207: 593 Remove the uio_yield prototype and symbol. This function has 594 been misnamed since it was introduced and should not be 595 globally exposed with this name. The equivalent functionality 596 is now available using kern_yield(curthread->td_user_pri). 597 The function remains undocumented. 598 59920110112: 600 A SYSCTL_[ADD_]UQUAD was added for unsigned uint64_t pointers, 601 symmetric with the existing SYSCTL_[ADD_]QUAD. Type checking 602 for scalar sysctls is defined but disabled. Code that needs 603 UQUAD to pass the type checking that must compile on older 604 systems where the define is not present can check against 605 __FreeBSD_version >= 900030. 606 607 The system dialog(1) has been replaced with a new version previously 608 in ports as devel/cdialog. dialog(1) is mostly command-line compatible 609 with the previous version, but the libdialog associated with it has 610 a largely incompatible API. As such, the original version of libdialog 611 will be kept temporarily as libodialog, until its base system consumers 612 are replaced or updated. Bump __FreeBSD_version to 900030. 613 61420110103: 615 If you are trying to run make universe on a -stable system, and you get 616 the following warning: 617 "Makefile", line 356: "Target architecture for i386/conf/GENERIC 618 unknown. config(8) likely too old." 619 or something similar to it, then you must upgrade your -stable system 620 to 8.2-Release or newer (really, any time after r210146 7/15/2010 in 621 stable/8) or build the config from the latest stable/8 branch and 622 install it on your system. 623 624 Prior to this date, building a current universe on 8-stable system from 625 between 7/15/2010 and 1/2/2011 would result in a weird shell parsing 626 error in the first kernel build phase. A new config on those old 627 systems will fix that problem for older versions of -current. 628 62920101228: 630 The TCP stack has been modified to allow Khelp modules to interact with 631 it via helper hook points and store per-connection data in the TCP 632 control block. Bump __FreeBSD_version to 900029. User space tools that 633 rely on the size of struct tcpcb in tcp_var.h (e.g. sockstat) need to 634 be recompiled. 635 63620101114: 637 Generic IEEE 802.3 annex 31B full duplex flow control support has been 638 added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along 639 with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted 640 to take advantage of it instead of using custom implementations. This 641 means that these drivers now no longer unconditionally advertise 642 support for flow control but only do so if flow control is a selected 643 media option. This was implemented in the generic support that way in 644 order to allow flow control to be switched on and off via ifconfig(8) 645 with the PHY specific default to typically off in order to protect 646 from unwanted effects. Consequently, if you used flow control with 647 one of the above mentioned drivers you now need to explicitly enable 648 it, for example via: 649 ifconfig bge0 media auto mediaopt flowcontrol 650 651 Along with the above mentioned changes generic support for setting 652 1000baseT master mode also has been added and brgphy(4), ciphy(4), 653 e1000phy(4) as well as ip1000phy(4) have been converted to take 654 advantage of it. This means that these drivers now no longer take the 655 link0 parameter for selecting master mode but the master media option 656 has to be used instead, for example like in the following: 657 ifconfig bge0 media 1000baseT mediaopt full-duplex,master 658 659 Selection of master mode now is also available with all other PHY 660 drivers supporting 1000baseT. 661 66220101111: 663 The TCP stack has received a significant update to add support for 664 modularised congestion control and generally improve the clarity of 665 congestion control decisions. Bump __FreeBSD_version to 900025. User 666 space tools that rely on the size of struct tcpcb in tcp_var.h (e.g. 667 sockstat) need to be recompiled. 668 66920101002: 670 The man(1) utility has been replaced by a new version that no longer 671 uses /etc/manpath.config. Please consult man.conf(5) for how to 672 migrate local entries to the new format. 673 67420100928: 675 The copyright strings printed by login(1) and sshd(8) at the time of a 676 new connection have been removed to follow other operating systems and 677 upstream sshd. 678 67920100915: 680 A workaround for a fixed ld bug has been removed in kernel code, 681 so make sure that your system ld is built from sources after 682 revision 210245 from 2010-07-19 (r211583 if building head kernel 683 on stable/8, r211584 for stable/7; both from 2010-08-21). 684 A symptom of incorrect ld version is different addresses for 685 set_pcpu section and __start_set_pcpu symbol in kernel and/or modules. 686 68720100913: 688 The $ipv6_prefer variable in rc.conf(5) has been split into 689 $ip6addrctl_policy and $ipv6_activate_all_interfaces. 690 691 The $ip6addrctl_policy is a variable to choose a pre-defined 692 address selection policy set by ip6addrctl(8). A value 693 "ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The 694 default is "AUTO". 695 696 The $ipv6_activate_all_interfaces specifies whether IFDISABLED 697 flag (see an entry of 20090926) is set on an interface with no 698 corresponding $ifconfig_IF_ipv6 line. The default is "NO" for 699 security reason. If you want IPv6 link-local address on all 700 interfaces by default, set this to "YES". 701 702 The old ipv6_prefer="YES" is equivalent to 703 ipv6_activate_all_interfaces="YES" and 704 ip6addrctl_policy="ipv6_prefer". 705 70620100913: 707 DTrace has grown support for userland tracing. Due to this, DTrace is 708 now i386 and amd64 only. 709 dtruss(1) is now installed by default on those systems and a new 710 kernel module is needed for userland tracing: fasttrap. 711 No changes to your kernel config file are necessary to enable 712 userland tracing, but you might consider adding 'STRIP=' and 713 'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want 714 to have informative userland stack traces in DTrace (ustack). 715 71620100725: 717 The acpi_aiboost(4) driver has been removed in favor of the new 718 aibs(4) driver. You should update your kernel configuration file. 719 72020100722: 721 BSD grep has been imported to the base system and it is built by 722 default. It is completely BSD licensed, highly GNU-compatible, uses 723 less memory than its GNU counterpart and has a small codebase. 724 However, it is slower than its GNU counterpart, which is mostly 725 noticeable for larger searches, for smaller ones it is measurable 726 but not significant. The reason is complex, the most important factor 727 is that we lack a modern and efficient regex library and GNU 728 overcomes this by optimizing the searches internally. Future work 729 on improving the regex performance is planned, for the meantime, 730 users that need better performance, can build GNU grep instead by 731 setting the WITH_GNU_GREP knob. 732 73320100713: 734 Due to the import of powerpc64 support, all existing powerpc kernel 735 configuration files must be updated with a machine directive like this: 736 machine powerpc powerpc 737 738 In addition, an updated config(8) is required to build powerpc kernels 739 after this change. 740 74120100713: 742 A new version of ZFS (version 15) has been merged to -HEAD. 743 This version uses a python library for the following subcommands: 744 zfs allow, zfs unallow, zfs groupspace, zfs userspace. 745 For full functionality of these commands the following port must 746 be installed: sysutils/py-zfs 747 74820100429: 749 'vm_page's are now hashed by physical address to an array of mutexes. 750 Currently this is only used to serialize access to hold_count. Over 751 time the page queue mutex will be peeled away. This changes the size 752 of pmap on every architecture. And requires all callers of vm_page_hold 753 and vm_page_unhold to be updated. 754 75520100402: 756 WITH_CTF can now be specified in src.conf (not recommended, there 757 are some problems with static executables), make.conf (would also 758 affect ports which do not use GNU make and do not override the 759 compile targets) or in the kernel config (via "makeoptions 760 WITH_CTF=yes"). 761 When WITH_CTF was specified there before this was silently ignored, 762 so make sure that WITH_CTF is not used in places which could lead 763 to unwanted behavior. 764 76520100311: 766 The kernel option COMPAT_IA32 has been replaced with COMPAT_FREEBSD32 767 to allow 32-bit compatibility on non-x86 platforms. All kernel 768 configurations on amd64 and ia64 platforms using these options must 769 be modified accordingly. 770 77120100113: 772 The utmp user accounting database has been replaced with utmpx, 773 the user accounting interface standardized by POSIX. 774 Unfortunately the semantics of utmp and utmpx don't match, 775 making it practically impossible to support both interfaces. 776 The user accounting database is used by tools like finger(1), 777 last(1), talk(1), w(1) and ac(8). 778 779 All applications in the base system use utmpx. This means only 780 local binaries (e.g. from the ports tree) may still use these 781 utmp database files. These applications must be rebuilt to make 782 use of utmpx. 783 784 After the system has been upgraded, it is safe to remove the old 785 log files (/var/run/utmp, /var/log/lastlog and /var/log/wtmp*), 786 assuming their contents is of no importance anymore. Old wtmp 787 databases can only be used by last(1) and ac(8) after they have 788 been converted to the new format using wtmpcvt(1). 789 79020100108: 791 Introduce the kernel thread "deadlock resolver" (which can be enabled 792 via the DEADLKRES option, see NOTES for more details) and the 793 sleepq_type() function for sleepqueues. 794 79520091202: 796 The rc.firewall and rc.firewall6 were unified, and 797 rc.firewall6 and rc.d/ip6fw were removed. 798 According to the removal of rc.d/ip6fw, ipv6_firewall_* rc 799 variables are obsoleted. Instead, the following new rc 800 variables are added to rc.d/ipfw: 801 802 firewall_client_net_ipv6, firewall_simple_iif_ipv6, 803 firewall_simple_inet_ipv6, firewall_simple_oif_ipv6, 804 firewall_simple_onet_ipv6, firewall_trusted_ipv6 805 806 The meanings correspond to the relevant IPv4 variables. 807 80820091125: 809 8.0-RELEASE. 810 81120091113: 812 The default terminal emulation for syscons(4) has been changed 813 from cons25 to xterm on all platforms except pc98. This means 814 that the /etc/ttys file needs to be updated to ensure correct 815 operation of applications on the console. 816 817 The terminal emulation style can be toggled per window by using 818 vidcontrol(1)'s -T flag. The TEKEN_CONS25 kernel configuration 819 options can be used to change the compile-time default back to 820 cons25. 821 822 To prevent graphical artifacts, make sure the TERM environment 823 variable is set to match the terminal emulation that is being 824 performed by syscons(4). 825 82620091109: 827 The layout of the structure ieee80211req_scan_result has changed. 828 Applications that require wireless scan results (e.g. ifconfig(8)) 829 from net80211 need to be recompiled. 830 831 Applications such as wpa_supplicant(8) may require a full world 832 build without using NO_CLEAN in order to get synchronized with the 833 new structure. 834 83520091025: 836 The iwn(4) driver has been updated to support the 5000 and 5150 series. 837 There's one kernel module for each firmware. Adding "device iwnfw" 838 to the kernel configuration file means including all three firmware 839 images inside the kernel. If you want to include just the one for 840 your wireless card, use the devices iwn4965fw, iwn5000fw or 841 iwn5150fw. 842 84320090926: 844 The rc.d/network_ipv6, IPv6 configuration script has been integrated 845 into rc.d/netif. The changes are the following: 846 847 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF 848 for IPv4. For aliases, $ifconfig_IF_aliasN should be used. 849 Note that both variables need the "inet6" keyword at the head. 850 851 Do not set $ipv6_network_interfaces manually if you do not 852 understand what you are doing. It is not needed in most cases. 853 854 $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but 855 they are obsolete. 856 857 2. $ipv6_enable is obsolete. Use $ipv6_prefer and 858 "inet6 accept_rtadv" keyword in ifconfig(8) instead. 859 860 If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and 861 all configured interfaces have "inet6 accept_rtadv" in the 862 $ifconfig_IF_ipv6. These are for backward compatibility. 863 864 3. A new variable $ipv6_prefer has been added. If NO, IPv6 865 functionality of interfaces with no corresponding 866 $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag, 867 and the default address selection policy of ip6addrctl(8) 868 is the IPv4-preferred one (see rc.d/ip6addrctl for more details). 869 Note that if you want to configure IPv6 functionality on the 870 disabled interfaces after boot, first you need to clear the flag by 871 using ifconfig(8) like: 872 873 ifconfig em0 inet6 -ifdisabled 874 875 If YES, the default address selection policy is set as 876 IPv6-preferred. 877 878 The default value of $ipv6_prefer is NO. 879 880 4. If your system need to receive Router Advertisement messages, 881 define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8) 882 scripts automatically invoke rtsol(8) when the interface becomes 883 UP. The Router Advertisement messages are used for SLAAC 884 (State-Less Address AutoConfiguration). 885 88620090922: 887 802.11s D3.03 support was committed. This is incompatible with the 888 previous code, which was based on D3.0. 889 89020090912: 891 A sysctl variable net.inet6.ip6.accept_rtadv now sets the default value 892 of a per-interface flag ND6_IFF_ACCEPT_RTADV, not a global knob to 893 control whether accepting Router Advertisement messages or not. 894 Also, a per-interface flag ND6_IFF_AUTO_LINKLOCAL has been added and 895 a sysctl variable net.inet6.ip6.auto_linklocal is its default value. 896 The ifconfig(8) utility now supports these flags. 897 89820090910: 899 ZFS snapshots are now mounted with MNT_IGNORE flag. Use -v option for 900 mount(8) and -a option for df(1) to see them. 901 90220090825: 903 The old tunable hw.bus.devctl_disable has been superseded by 904 hw.bus.devctl_queue. hw.bus.devctl_disable=1 in loader.conf should be 905 replaced by hw.bus.devctl_queue=0. The default for this new tunable 906 is 1000. 907 90820090813: 909 Remove the option STOP_NMI. The default action is now to use NMI only 910 for KDB via the newly introduced function stop_cpus_hard() and 911 maintain stop_cpus() to just use a normal IPI_STOP on ia32 and amd64. 912 91320090803: 914 The stable/8 branch created in subversion. This corresponds to the 915 RELENG_8 branch in CVS. 916 91720090719: 918 Bump the shared library version numbers for all libraries that do not 919 use symbol versioning as part of the 8.0-RELEASE cycle. Bump 920 __FreeBSD_version to 800105. 921 92220090714: 923 Due to changes in the implementation of virtual network stack support, 924 all network-related kernel modules must be recompiled. As this change 925 breaks the ABI, bump __FreeBSD_version to 800104. 926 92720090713: 928 The TOE interface to the TCP syncache has been modified to remove 929 struct tcpopt (<netinet/tcp_var.h>) from the ABI of the network stack. 930 The cxgb driver is the only TOE consumer affected by this change, and 931 needs to be recompiled along with the kernel. As this change breaks 932 the ABI, bump __FreeBSD_version to 800103. 933 93420090712: 935 Padding has been added to struct tcpcb, sackhint and tcpstat in 936 <netinet/tcp_var.h> to facilitate future MFCs and bug fixes whilst 937 maintaining the ABI. However, this change breaks the ABI, so bump 938 __FreeBSD_version to 800102. User space tools that rely on the size of 939 any of these structs (e.g. sockstat) need to be recompiled. 940 94120090630: 942 The NFS_LEGACYRPC option has been removed along with the old kernel 943 RPC implementation that this option selected. Kernel configurations 944 may need to be adjusted. 945 94620090629: 947 The network interface device nodes at /dev/net/<interface> have been 948 removed. All ioctl operations can be performed the normal way using 949 routing sockets. The kqueue functionality can generally be replaced 950 with routing sockets. 951 95220090628: 953 The documentation from the FreeBSD Documentation Project (Handbook, 954 FAQ, etc.) is now installed via packages by sysinstall(8) and under 955 the /usr/local/share/doc/freebsd directory instead of /usr/share/doc. 956 95720090624: 958 The ABI of various structures related to the SYSV IPC API have been 959 changed. As a result, the COMPAT_FREEBSD[456] and COMPAT_43 kernel 960 options now all require COMPAT_FREEBSD7. Bump __FreeBSD_version to 961 800100. 962 96320090622: 964 Layout of struct vnet has changed as routing related variables were 965 moved to their own Vimage module. Modules need to be recompiled. Bump 966 __FreeBSD_version to 800099. 967 96820090619: 969 NGROUPS_MAX and NGROUPS have been increased from 16 to 1023 and 1024 970 respectively. As long as no more than 16 groups per process are used, 971 no changes should be visible. When more than 16 groups are used, old 972 binaries may fail if they call getgroups() or getgrouplist() with 973 statically sized storage. Recompiling will work around this, but 974 applications should be modified to use dynamically allocated storage 975 for group arrays as POSIX.1-2008 does not cap an implementation's 976 number of supported groups at NGROUPS_MAX+1 as previous versions did. 977 978 NFS and portalfs mounts may also be affected as the list of groups is 979 truncated to 16. Users of NFS who use more than 16 groups, should 980 take care that negative group permissions are not used on the exported 981 file systems as they will not be reliable unless a GSSAPI based 982 authentication method is used. 983 98420090616: 985 The compiling option ADAPTIVE_LOCKMGRS has been introduced. This 986 option compiles in the support for adaptive spinning for lockmgrs 987 which want to enable it. The lockinit() function now accepts the flag 988 LK_ADAPTIVE in order to make the lock object subject to adaptive 989 spinning when both held in write and read mode. 990 99120090613: 992 The layout of the structure returned by IEEE80211_IOC_STA_INFO has 993 changed. User applications that use this ioctl need to be rebuilt. 994 99520090611: 996 The layout of struct thread has changed. Kernel and modules need to 997 be rebuilt. 998 99920090608: 1000 The layout of structs ifnet, domain, protosw and vnet_net has changed. 1001 Kernel modules need to be rebuilt. Bump __FreeBSD_version to 800097. 1002 100320090602: 1004 window(1) has been removed from the base system. It can now be 1005 installed from ports. The port is called misc/window. 1006 100720090601: 1008 The way we are storing and accessing `routing table' entries has 1009 changed. Programs reading the FIB, like netstat, need to be 1010 re-compiled. 1011 101220090601: 1013 A new netisr implementation has been added for FreeBSD 8. Network 1014 file system modules, such as igmp, ipdivert, and others, should be 1015 rebuilt. 1016 Bump __FreeBSD_version to 800096. 1017 101820090530: 1019 Remove the tunable/sysctl debug.mpsafevfs as its initial purpose is no 1020 more valid. 1021 102220090530: 1023 Add VOP_ACCESSX(9). File system modules need to be rebuilt. 1024 Bump __FreeBSD_version to 800094. 1025 102620090529: 1027 Add mnt_xflag field to 'struct mount'. File system modules need to be 1028 rebuilt. 1029 Bump __FreeBSD_version to 800093. 1030 103120090528: 1032 The compiling option ADAPTIVE_SX has been retired while it has been 1033 introduced the option NO_ADAPTIVE_SX which handles the reversed logic. 1034 The KPI for sx_init_flags() changes as accepting flags: 1035 SX_ADAPTIVESPIN flag has been retired while the SX_NOADAPTIVE flag has 1036 been introduced in order to handle the reversed logic. 1037 Bump __FreeBSD_version to 800092. 1038 103920090527: 1040 Add support for hierarchical jails. Remove global securelevel. 1041 Bump __FreeBSD_version to 800091. 1042 104320090523: 1044 The layout of struct vnet_net has changed, therefore modules 1045 need to be rebuilt. 1046 Bump __FreeBSD_version to 800090. 1047 104820090523: 1049 The newly imported zic(8) produces a new format in the output. Please 1050 run tzsetup(8) to install the newly created data to /etc/localtime. 1051 105220090520: 1053 The sysctl tree for the usb stack has renamed from hw.usb2.* to 1054 hw.usb.* and is now consistent again with previous releases. 1055 105620090520: 1057 802.11 monitor mode support was revised and driver api's were changed. 1058 Drivers dependent on net80211 now support DLT_IEEE802_11_RADIO instead 1059 of DLT_IEEE802_11. No user-visible data structures were changed but 1060 applications that use DLT_IEEE802_11 may require changes. 1061 Bump __FreeBSD_version to 800088. 1062 106320090430: 1064 The layout of the following structs has changed: sysctl_oid, 1065 socket, ifnet, inpcbinfo, tcpcb, syncache_head, vnet_inet, 1066 vnet_inet6 and vnet_ipfw. Most modules need to be rebuild or 1067 panics may be experienced. World rebuild is required for 1068 correctly checking networking state from userland. 1069 Bump __FreeBSD_version to 800085. 1070 107120090429: 1072 MLDv2 and Source-Specific Multicast (SSM) have been merged 1073 to the IPv6 stack. VIMAGE hooks are in but not yet used. 1074 The implementation of SSM within FreeBSD's IPv6 stack closely 1075 follows the IPv4 implementation. 1076 1077 For kernel developers: 1078 1079 * The most important changes are that the ip6_output() and 1080 ip6_input() paths no longer take the IN6_MULTI_LOCK, 1081 and this lock has been downgraded to a non-recursive mutex. 1082 1083 * As with the changes to the IPv4 stack to support SSM, filtering 1084 of inbound multicast traffic must now be performed by transport 1085 protocols within the IPv6 stack. This does not apply to TCP and 1086 SCTP, however, it does apply to UDP in IPv6 and raw IPv6. 1087 1088 * The KPIs used by IPv6 multicast are similar to those used by 1089 the IPv4 stack, with the following differences: 1090 * im6o_mc_filter() is analogous to imo_multicast_filter(). 1091 * The legacy KAME entry points in6_joingroup and in6_leavegroup() 1092 are shimmed to in6_mc_join() and in6_mc_leave() respectively. 1093 * IN6_LOOKUP_MULTI() has been deprecated and removed. 1094 * IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs 1095 for MLDv1 have an additional 'timer' argument which is used to 1096 jitter the initial membership report for the solicited-node 1097 multicast membership on-link. 1098 * This is not strictly needed for MLDv2, which already jitters 1099 its report transmissions. However, the 'timer' argument is 1100 preserved in case MLDv1 is active on the interface. 1101 1102 * The KAME linked-list based IPv6 membership implementation has 1103 been refactored to use a vector similar to that used by the IPv4 1104 stack. 1105 Code which maintains a list of its own multicast memberships 1106 internally, e.g. carp, has been updated to reflect the new 1107 semantics. 1108 1109 * There is a known Lock Order Reversal (LOR) due to in6_setscope() 1110 acquiring the IF_AFDATA_LOCK and being called within ip6_output(). 1111 Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an 1112 implementation constraint which needs to be addressed in HEAD. 1113 1114 For application developers: 1115 1116 * The changes are broadly similar to those made for the IPv4 1117 stack. 1118 1119 * The use of IPv4 and IPv6 multicast socket options on the same 1120 socket, using mapped addresses, HAS NOT been tested or supported. 1121 1122 * There are a number of issues with the implementation of various 1123 IPv6 multicast APIs which need to be resolved in the API surface 1124 before the implementation is fully compatible with KAME userland 1125 use, and these are mostly to do with interface index treatment. 1126 1127 * The literature available discusses the use of either the delta / ASM 1128 API with setsockopt(2)/getsockopt(2), or the full-state / ASM API 1129 using setsourcefilter(3)/getsourcefilter(3). For more information 1130 please refer to RFC 3768, 'Socket Interface Extensions for 1131 Multicast Source Filters'. 1132 1133 * Applications which use the published RFC 3678 APIs should be fine. 1134 1135 For systems administrators: 1136 1137 * The mtest(8) utility has been refactored to support IPv6, in 1138 addition to IPv4. Interface addresses are no longer accepted 1139 as arguments, their names must be used instead. The utility 1140 will map the interface name to its first IPv4 address as 1141 returned by getifaddrs(3). 1142 1143 * The ifmcstat(8) utility has also been updated to print the MLDv2 1144 endpoint state and source filter lists via sysctl(3). 1145 1146 * The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable 1147 loopback of IPv6 multicast datagrams by default; it defaults to 1 1148 to preserve the existing behaviour. Disabling multicast loopback is 1149 recommended for optimal system performance. 1150 1151 * The IPv6 MROUTING code has been changed to examine this sysctl 1152 instead of attempting to perform a group lookup before looping 1153 back forwarded datagrams. 1154 1155 Bump __FreeBSD_version to 800084. 1156 115720090422: 1158 Implement low-level Bluetooth HCI API. 1159 Bump __FreeBSD_version to 800083. 1160 116120090419: 1162 The layout of struct malloc_type, used by modules to register new 1163 memory allocation types, has changed. Most modules will need to 1164 be rebuilt or panics may be experienced. 1165 Bump __FreeBSD_version to 800081. 1166 116720090415: 1168 Anticipate overflowing inp_flags - add inp_flags2. 1169 This changes most offsets in inpcb, so checking v4 connection 1170 state will require a world rebuild. 1171 Bump __FreeBSD_version to 800080. 1172 117320090415: 1174 Add an llentry to struct route and struct route_in6. Modules 1175 embedding a struct route will need to be recompiled. 1176 Bump __FreeBSD_version to 800079. 1177 117820090414: 1179 The size of rt_metrics_lite and by extension rtentry has changed. 1180 Networking administration apps will need to be recompiled. 1181 The route command now supports show as an alias for get, weighting 1182 of routes, sticky and nostick flags to alter the behavior of stateful 1183 load balancing. 1184 Bump __FreeBSD_version to 800078. 1185 118620090408: 1187 Do not use Giant for kbdmux(4) locking. This is wrong and 1188 apparently causing more problems than it solves. This will 1189 re-open the issue where interrupt handlers may race with 1190 kbdmux(4) in polling mode. Typical symptoms include (but 1191 not limited to) duplicated and/or missing characters when 1192 low level console functions (such as gets) are used while 1193 interrupts are enabled (for example geli password prompt, 1194 mountroot prompt etc.). Disabling kbdmux(4) may help. 1195 119620090407: 1197 The size of structs vnet_net, vnet_inet and vnet_ipfw has changed; 1198 kernel modules referencing any of the above need to be recompiled. 1199 Bump __FreeBSD_version to 800075. 1200 120120090320: 1202 GEOM_PART has become the default partition slicer for storage devices, 1203 replacing GEOM_MBR, GEOM_BSD, GEOM_PC98 and GEOM_GPT slicers. It 1204 introduces some changes: 1205 1206 MSDOS/EBR: the devices created from MSDOS extended partition entries 1207 (EBR) can be named differently than with GEOM_MBR and are now symlinks 1208 to devices with offset-based names. fstabs may need to be modified. 1209 1210 BSD: the "geometry does not match label" warning is harmless in most 1211 cases but it points to problems in file system misalignment with 1212 disk geometry. The "c" partition is now implicit, covers the whole 1213 top-level drive and cannot be (mis)used by users. 1214 1215 General: Kernel dumps are now not allowed to be written to devices 1216 whose partition types indicate they are meant to be used for file 1217 systems (or, in case of MSDOS partitions, as something else than 1218 the "386BSD" type). 1219 1220 Most of these changes date approximately from 200812. 1221 122220090319: 1223 The uscanner(4) driver has been removed from the kernel. This follows 1224 Linux removing theirs in 2.6 and making libusb the default interface 1225 (supported by sane). 1226 122720090319: 1228 The multicast forwarding code has been cleaned up. netstat(1) 1229 only relies on KVM now for printing bandwidth upcall meters. 1230 The IPv4 and IPv6 modules are split into ip_mroute_mod and 1231 ip6_mroute_mod respectively. The config(5) options for statically 1232 compiling this code remain the same, i.e. 'options MROUTING'. 1233 123420090315: 1235 Support for the IFF_NEEDSGIANT network interface flag has been 1236 removed, which means that non-MPSAFE network device drivers are no 1237 longer supported. In particular, if_ar, if_sr, and network device 1238 drivers from the old (legacy) USB stack can no longer be built or 1239 used. 1240 124120090313: 1242 POSIX.1 Native Language Support (NLS) has been enabled in libc and 1243 a bunch of new language catalog files have also been added. 1244 This means that some common libc messages are now localized and 1245 they depend on the LC_MESSAGES environmental variable. 1246 124720090313: 1248 The k8temp(4) driver has been renamed to amdtemp(4) since 1249 support for Family 10 and Family 11 CPU families was added. 1250 125120090309: 1252 IGMPv3 and Source-Specific Multicast (SSM) have been merged 1253 to the IPv4 stack. VIMAGE hooks are in but not yet used. 1254 1255 For kernel developers, the most important changes are that the 1256 ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(), 1257 and this lock has been downgraded to a non-recursive mutex. 1258 1259 Transport protocols (UDP, Raw IP) are now responsible for filtering 1260 inbound multicast traffic according to group membership and source 1261 filters. The imo_multicast_filter() KPI exists for this purpose. 1262 Transports which do not use multicast (SCTP, TCP) already reject 1263 multicast by default. Forwarding and receive performance may improve 1264 as a mutex acquisition is no longer needed in the ip_input() 1265 low-level input path. in_addmulti() and in_delmulti() are shimmed 1266 to new KPIs which exist to support SSM in-kernel. 1267 1268 For application developers, it is recommended that loopback of 1269 multicast datagrams be disabled for best performance, as this 1270 will still cause the lock to be taken for each looped-back 1271 datagram transmission. The net.inet.ip.mcast.loop sysctl may 1272 be tuned to 0 to disable loopback by default; it defaults to 1 1273 to preserve the existing behaviour. 1274 1275 For systems administrators, to obtain best performance with 1276 multicast reception and multiple groups, it is always recommended 1277 that a card with a suitably precise hash filter is used. Hash 1278 collisions will still result in the lock being taken within the 1279 transport protocol input path to check group membership. 1280 1281 If deploying FreeBSD in an environment with IGMP snooping switches, 1282 it is recommended that the net.inet.igmp.sendlocal sysctl remain 1283 enabled; this forces 224.0.0.0/24 group membership to be announced 1284 via IGMP. 1285 1286 The size of 'struct igmpstat' has changed; netstat needs to be 1287 recompiled to reflect this. 1288 Bump __FreeBSD_version to 800070. 1289 129020090309: 1291 libusb20.so.1 is now installed as libusb.so.1 and the ports system 1292 updated to use it. This requires a buildworld/installworld in order to 1293 update the library and dependencies (usbconfig, etc). Its advisable to 1294 rebuild all ports which uses libusb. More specific directions are given 1295 in the ports collection UPDATING file. Any /etc/libmap.conf entries for 1296 libusb are no longer required and can be removed. 1297 129820090302: 1299 A workaround is committed to allow the creation of System V shared 1300 memory segment of size > 2 GB on the 64-bit architectures. 1301 Due to a limitation of the existing ABI, the shm_segsz member 1302 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is 1303 wrong for large segments. Note that limits must be explicitly 1304 raised to allow such segments to be created. 1305 130620090301: 1307 The layout of struct ifnet has changed, requiring a rebuild of all 1308 network device driver modules. 1309 131020090227: 1311 The /dev handling for the new USB stack has changed, a 1312 buildworld/installworld is required for libusb20. 1313 131420090223: 1315 The new USB2 stack has now been permanently moved in and all kernel and 1316 module names reverted to their previous values (eg, usb, ehci, ohci, 1317 ums, ...). The old usb stack can be compiled in by prefixing the name 1318 with the letter 'o', the old usb modules have been removed. 1319 Updating entry 20090216 for xorg and 20090215 for libmap may still 1320 apply. 1321 132220090217: 1323 The rc.conf(5) option if_up_delay has been renamed to 1324 defaultroute_delay to better reflect its purpose. If you have 1325 customized this setting in /etc/rc.conf you need to update it to 1326 use the new name. 1327 132820090216: 1329 xorg 7.4 wants to configure its input devices via hald which does not 1330 yet work with USB2. If the keyboard/mouse does not work in xorg then 1331 add 1332 Option "AllowEmptyInput" "off" 1333 to your ServerLayout section. This will cause X to use the configured 1334 kbd and mouse sections from your xorg.conf. 1335 133620090215: 1337 The GENERIC kernels for all architectures now default to the new USB2 1338 stack. No kernel config options or code have been removed so if a 1339 problem arises please report it and optionally revert to the old USB 1340 stack. If you are loading USB kernel modules or have a custom kernel 1341 that includes GENERIC then ensure that usb names are also changed over, 1342 eg uftdi -> usb2_serial_ftdi. 1343 1344 Older programs linked against the ports libusb 0.1 need to be 1345 redirected to the new stack's libusb20. /etc/libmap.conf can 1346 be used for this: 1347 # Map old usb library to new one for usb2 stack 1348 libusb-0.1.so.8 libusb20.so.1 1349 135020090209: 1351 All USB ethernet devices now attach as interfaces under the name ueN 1352 (eg. ue0). This is to provide a predictable name as vendors often 1353 change usb chipsets in a product without notice. 1354 135520090203: 1356 The ichsmb(4) driver has been changed to require SMBus slave 1357 addresses be left-justified (xxxxxxx0b) rather than right-justified. 1358 All of the other SMBus controller drivers require left-justified 1359 slave addresses, so this change makes all the drivers provide the 1360 same interface. 1361 136220090201: 1363 INET6 statistics (struct ip6stat) was updated. 1364 netstat(1) needs to be recompiled. 1365 136620090119: 1367 NTFS has been removed from GENERIC kernel on amd64 to match 1368 GENERIC on i386. Should not cause any issues since mount_ntfs(8) 1369 will load ntfs.ko module automatically when NTFS support is 1370 actually needed, unless ntfs.ko is not installed or security 1371 level prohibits loading kernel modules. If either is the case, 1372 "options NTFS" has to be added into kernel config. 1373 137420090115: 1375 TCP Appropriate Byte Counting (RFC 3465) support added to kernel. 1376 New field in struct tcpcb breaks ABI, so bump __FreeBSD_version to 1377 800061. User space tools that rely on the size of struct tcpcb in 1378 tcp_var.h (e.g. sockstat) need to be recompiled. 1379 138020081225: 1381 ng_tty(4) module updated to match the new TTY subsystem. 1382 Due to API change, user-level applications must be updated. 1383 New API support added to mpd5 CVS and expected to be present 1384 in next mpd5.3 release. 1385 138620081219: 1387 With __FreeBSD_version 800060 the makefs tool is part of 1388 the base system (it was a port). 1389 139020081216: 1391 The afdata and ifnet locks have been changed from mutexes to 1392 rwlocks, network modules will need to be re-compiled. 1393 139420081214: 1395 __FreeBSD_version 800059 incorporates the new arp-v2 rewrite. 1396 RTF_CLONING, RTF_LLINFO and RTF_WASCLONED flags are eliminated. 1397 The new code reduced struct rtentry{} by 16 bytes on 32-bit 1398 architecture and 40 bytes on 64-bit architecture. The userland 1399 applications "arp" and "ndp" have been updated accordingly. 1400 The output from "netstat -r" shows only routing entries and 1401 none of the L2 information. 1402 140320081130: 1404 __FreeBSD_version 800057 marks the switchover from the 1405 binary ath hal to source code. Users must add the line: 1406 1407 options AH_SUPPORT_AR5416 1408 1409 to their kernel config files when specifying: 1410 1411 device ath_hal 1412 1413 The ath_hal module no longer exists; the code is now compiled 1414 together with the driver in the ath module. It is now 1415 possible to tailor chip support (i.e. reduce the set of chips 1416 and thereby the code size); consult ath_hal(4) for details. 1417 141820081121: 1419 __FreeBSD_version 800054 adds memory barriers to 1420 <machine/atomic.h>, new interfaces to ifnet to facilitate 1421 multiple hardware transmit queues for cards that support 1422 them, and a lock-less ring-buffer implementation to 1423 enable drivers to more efficiently manage queueing of 1424 packets. 1425 142620081117: 1427 A new version of ZFS (version 13) has been merged to -HEAD. 1428 This version has zpool attribute "listsnapshots" off by 1429 default, which means "zfs list" does not show snapshots, 1430 and is the same as Solaris behavior. 1431 143220081028: 1433 dummynet(4) ABI has changed. ipfw(8) needs to be recompiled. 1434 143520081009: 1436 The uhci, ohci, ehci and slhci USB Host controller drivers have 1437 been put into separate modules. If you load the usb module 1438 separately through loader.conf you will need to load the 1439 appropriate *hci module as well. E.g. for a UHCI-based USB 2.0 1440 controller add the following to loader.conf: 1441 1442 uhci_load="YES" 1443 ehci_load="YES" 1444 144520081009: 1446 The ABI used by the PMC toolset has changed. Please keep 1447 userland (libpmc(3)) and the kernel module (hwpmc(4)) in 1448 sync. 1449 145020081009: 1451 atapci kernel module now includes only generic PCI ATA 1452 driver. AHCI driver moved to ataahci kernel module. 1453 All vendor-specific code moved into separate kernel modules: 1454 ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, 1455 atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, 1456 atamarvell, atamicron, atanational, atanetcell, atanvidia, 1457 atapromise, ataserverworks, atasiliconimage, atasis, atavia 1458 145920080820: 1460 The TTY subsystem of the kernel has been replaced by a new 1461 implementation, which provides better scalability and an 1462 improved driver model. Most common drivers have been migrated to 1463 the new TTY subsystem, while others have not. The following 1464 drivers have not yet been ported to the new TTY layer: 1465 1466 PCI/ISA: 1467 cy, digi, rc, rp, sio 1468 1469 USB: 1470 ubser, ucycom 1471 1472 Line disciplines: 1473 ng_h4, ng_tty, ppp, sl, snp 1474 1475 Adding these drivers to your kernel configuration file shall 1476 cause compilation to fail. 1477 147820080818: 1479 ntpd has been upgraded to 4.2.4p5. 1480 148120080801: 1482 OpenSSH has been upgraded to 5.1p1. 1483 1484 For many years, FreeBSD's version of OpenSSH preferred DSA 1485 over RSA for host and user authentication keys. With this 1486 upgrade, we've switched to the vendor's default of RSA over 1487 DSA. This may cause upgraded clients to warn about unknown 1488 host keys even for previously known hosts. Users should 1489 follow the usual procedure for verifying host keys before 1490 accepting the RSA key. 1491 1492 This can be circumvented by setting the "HostKeyAlgorithms" 1493 option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh 1494 command line. 1495 1496 Please note that the sequence of keys offered for 1497 authentication has been changed as well. You may want to 1498 specify IdentityFile in a different order to revert this 1499 behavior. 1500 150120080713: 1502 The sio(4) driver has been removed from the i386 and amd64 1503 kernel configuration files. This means uart(4) is now the 1504 default serial port driver on those platforms as well. 1505 1506 To prevent collisions with the sio(4) driver, the uart(4) driver 1507 uses different names for its device nodes. This means the 1508 onboard serial port will now most likely be called "ttyu0" 1509 instead of "ttyd0". You may need to reconfigure applications to 1510 use the new device names. 1511 1512 When using the serial port as a boot console, be sure to update 1513 /boot/device.hints and /etc/ttys before booting the new kernel. 1514 If you forget to do so, you can still manually specify the hints 1515 at the loader prompt: 1516 1517 set hint.uart.0.at="isa" 1518 set hint.uart.0.port="0x3F8" 1519 set hint.uart.0.flags="0x10" 1520 set hint.uart.0.irq="4" 1521 boot -s 1522 152320080609: 1524 The gpt(8) utility has been removed. Use gpart(8) to partition 1525 disks instead. 1526 152720080603: 1528 The version that Linuxulator emulates was changed from 2.4.2 1529 to 2.6.16. If you experience any problems with Linux binaries 1530 please try to set sysctl compat.linux.osrelease to 2.4.2 and 1531 if it fixes the problem contact emulation mailing list. 1532 153320080525: 1534 ISDN4BSD (I4B) was removed from the src tree. You may need to 1535 update a your kernel configuration and remove relevant entries. 1536 153720080509: 1538 I have checked in code to support multiple routing tables. 1539 See the man pages setfib(1) and setfib(2). 1540 This is a hopefully backwards compatible version, 1541 but to make use of it you need to compile your kernel 1542 with options ROUTETABLES=2 (or more up to 16). 1543 154420080420: 1545 The 802.11 wireless support was redone to enable multi-bss 1546 operation on devices that are capable. The underlying device 1547 is no longer used directly but instead wlanX devices are 1548 cloned with ifconfig. This requires changes to rc.conf files. 1549 For example, change: 1550 ifconfig_ath0="WPA DHCP" 1551 to 1552 wlans_ath0=wlan0 1553 ifconfig_wlan0="WPA DHCP" 1554 see rc.conf(5) for more details. In addition, mergemaster of 1555 /etc/rc.d is highly recommended. Simultaneous update of userland 1556 and kernel wouldn't hurt either. 1557 1558 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta 1559 modules were merged into the base wlan module. All references 1560 to these modules (e.g. in kernel config files) must be removed. 1561 156220080408: 1563 psm(4) has gained write(2) support in native operation level. 1564 Arbitrary commands can be written to /dev/psm%d and status can 1565 be read back from it. Therefore, an application is responsible 1566 for status validation and error recovery. It is a no-op in 1567 other operation levels. 1568 156920080312: 1570 Support for KSE threading has been removed from the kernel. To 1571 run legacy applications linked against KSE libmap.conf may 1572 be used. The following libmap.conf may be used to ensure 1573 compatibility with any prior release: 1574 1575 libpthread.so.1 libthr.so.1 1576 libpthread.so.2 libthr.so.2 1577 libkse.so.3 libthr.so.3 1578 157920080301: 1580 The layout of struct vmspace has changed. This affects libkvm 1581 and any executables that link against libkvm and use the 1582 kvm_getprocs() function. In particular, but not exclusively, 1583 it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1). 1584 The effects are minimal, but it's advisable to upgrade world 1585 nonetheless. 1586 158720080229: 1588 The latest em driver no longer has support in it for the 1589 82575 adapter, this is now moved to the igb driver. The 1590 split was done to make new features that are incompatible 1591 with older hardware easier to do. 1592 159320080220: 1594 The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4), 1595 likewise the kernel option is now GEOM_LINUX_LVM. 1596 159720080211: 1598 The default NFS mount mode has changed from UDP to TCP for 1599 increased reliability. If you rely on (insecurely) NFS 1600 mounting across a firewall you may need to update your 1601 firewall rules. 1602 160320080208: 1604 Belatedly note the addition of m_collapse for compacting 1605 mbuf chains. 1606 160720080126: 1608 The fts(3) structures have been changed to use adequate 1609 integer types for their members and so to be able to cope 1610 with huge file trees. The old fts(3) ABI is preserved 1611 through symbol versioning in libc, so third-party binaries 1612 using fts(3) should still work, although they will not take 1613 advantage of the extended types. At the same time, some 1614 third-party software might fail to build after this change 1615 due to unportable assumptions made in its source code about 1616 fts(3) structure members. Such software should be fixed 1617 by its vendor or, in the worst case, in the ports tree. 1618 FreeBSD_version 800015 marks this change for the unlikely 1619 case that a portable fix is impossible. 1620 162120080123: 1622 To upgrade to -current after this date, you must be running 1623 FreeBSD not older than 6.0-RELEASE. Upgrading to -current 1624 from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems. 1625 162620071128: 1627 The ADAPTIVE_GIANT kernel option has been retired because its 1628 functionality is the default now. 1629 163020071118: 1631 The AT keyboard emulation of sunkbd(4) has been turned on 1632 by default. In order to make the special symbols of the Sun 1633 keyboards driven by sunkbd(4) work under X these now have 1634 to be configured the same way as Sun USB keyboards driven 1635 by ukbd(4) (which also does AT keyboard emulation), f.e.: 1636 1637 Option "XkbLayout" "us" 1638 Option "XkbRules" "xorg" 1639 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 1640 164120071024: 1642 It has been decided that it is desirable to provide ABI 1643 backwards compatibility to the FreeBSD 4/5/6 versions of the 1644 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 1645 broken with the introduction of PCI domain support (see the 1646 20070930 entry). Unfortunately, this required the ABI of 1647 PCIOCGETCONF to be broken again in order to be able to 1648 provide backwards compatibility to the old version of that 1649 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 1650 again. As for prominent ports this affects neither pciutils 1651 nor xorg-server this time, the hal port needs to be rebuilt 1652 however. 1653 165420071020: 1655 The misnamed kthread_create() and friends have been renamed 1656 to kproc_create() etc. Many of the callers already 1657 used kproc_start().. 1658 I will return kthread_create() and friends in a while 1659 with implementations that actually create threads, not procs. 1660 Renaming corresponds with version 800002. 1661 166220071010: 1663 RELENG_7 branched. 1664 1665COMMON ITEMS: 1666 1667 General Notes 1668 ------------- 1669 Avoid using make -j when upgrading. While generally safe, there are 1670 sometimes problems using -j to upgrade. If your upgrade fails with 1671 -j, please try again without -j. From time to time in the past there 1672 have been problems using -j with buildworld and/or installworld. This 1673 is especially true when upgrading between "distant" versions (eg one 1674 that cross a major release boundary or several minor releases, or when 1675 several months have passed on the -current branch). 1676 1677 Sometimes, obscure build problems are the result of environment 1678 poisoning. This can happen because the make utility reads its 1679 environment when searching for values for global variables. To run 1680 your build attempts in an "environmental clean room", prefix all make 1681 commands with 'env -i '. See the env(1) manual page for more details. 1682 1683 When upgrading from one major version to another it is generally best 1684 to upgrade to the latest code in the currently installed branch first, 1685 then do an upgrade to the new branch. This is the best-tested upgrade 1686 path, and has the highest probability of being successful. Please try 1687 this approach before reporting problems with a major version upgrade. 1688 1689 ZFS notes 1690 --------- 1691 When upgrading the boot ZFS pool to a new version, always follow 1692 these two steps: 1693 1694 1.) recompile and reinstall the ZFS boot loader and boot block 1695 (this is part of "make buildworld" and "make installworld") 1696 1697 2.) update the ZFS boot block on your boot drive 1698 1699 The following example updates the ZFS boot block on the first 1700 partition (freebsd-boot) of a GPT partitioned drive ad0: 1701 "gpart bootcode -p /boot/gptzfsboot -i 1 ad0" 1702 1703 Non-boot pools do not need these updates. 1704 1705 To build a kernel 1706 ----------------- 1707 If you are updating from a prior version of FreeBSD (even one just 1708 a few days old), you should follow this procedure. It is the most 1709 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1710 1711 make kernel-toolchain 1712 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1713 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1714 1715 To test a kernel once 1716 --------------------- 1717 If you just want to boot a kernel once (because you are not sure 1718 if it works, or if you want to boot a known bad kernel to provide 1719 debugging information) run 1720 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1721 nextboot -k testkernel 1722 1723 To just build a kernel when you know that it won't mess you up 1724 -------------------------------------------------------------- 1725 This assumes you are already running a CURRENT system. Replace 1726 ${arch} with the architecture of your machine (e.g. "i386", 1727 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1728 1729 cd src/sys/${arch}/conf 1730 config KERNEL_NAME_HERE 1731 cd ../compile/KERNEL_NAME_HERE 1732 make depend 1733 make 1734 make install 1735 1736 If this fails, go to the "To build a kernel" section. 1737 1738 To rebuild everything and install it on the current system. 1739 ----------------------------------------------------------- 1740 # Note: sometimes if you are running current you gotta do more than 1741 # is listed here if you are upgrading from a really old current. 1742 1743 <make sure you have good level 0 dumps> 1744 make buildworld 1745 make kernel KERNCONF=YOUR_KERNEL_HERE 1746 [1] 1747 <reboot in single user> [3] 1748 mergemaster -p [5] 1749 make installworld 1750 mergemaster -i [4] 1751 make delete-old [6] 1752 <reboot> 1753 1754 1755 To cross-install current onto a separate partition 1756 -------------------------------------------------- 1757 # In this approach we use a separate partition to hold 1758 # current's root, 'usr', and 'var' directories. A partition 1759 # holding "/", "/usr" and "/var" should be about 2GB in 1760 # size. 1761 1762 <make sure you have good level 0 dumps> 1763 <boot into -stable> 1764 make buildworld 1765 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1766 <maybe newfs current's root partition> 1767 <mount current's root partition on directory ${CURRENT_ROOT}> 1768 make installworld DESTDIR=${CURRENT_ROOT} 1769 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1770 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1771 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1772 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1773 <reboot into current> 1774 <do a "native" rebuild/install as described in the previous section> 1775 <maybe install compatibility libraries from ports/misc/compat*> 1776 <reboot> 1777 1778 1779 To upgrade in-place from stable to current 1780 ---------------------------------------------- 1781 <make sure you have good level 0 dumps> 1782 make buildworld [9] 1783 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1784 [1] 1785 <reboot in single user> [3] 1786 mergemaster -p [5] 1787 make installworld 1788 mergemaster -i [4] 1789 make delete-old [6] 1790 <reboot> 1791 1792 Make sure that you've read the UPDATING file to understand the 1793 tweaks to various things you need. At this point in the life 1794 cycle of current, things change often and you are on your own 1795 to cope. The defaults can also change, so please read ALL of 1796 the UPDATING entries. 1797 1798 Also, if you are tracking -current, you must be subscribed to 1799 freebsd-current@freebsd.org. Make sure that before you update 1800 your sources that you have read and understood all the recent 1801 messages there. If in doubt, please track -stable which has 1802 much fewer pitfalls. 1803 1804 [1] If you have third party modules, such as vmware, you 1805 should disable them at this point so they don't crash your 1806 system on reboot. 1807 1808 [3] From the bootblocks, boot -s, and then do 1809 fsck -p 1810 mount -u / 1811 mount -a 1812 cd src 1813 adjkerntz -i # if CMOS is wall time 1814 Also, when doing a major release upgrade, it is required that 1815 you boot into single user mode to do the installworld. 1816 1817 [4] Note: This step is non-optional. Failure to do this step 1818 can result in a significant reduction in the functionality of the 1819 system. Attempting to do it by hand is not recommended and those 1820 that pursue this avenue should read this file carefully, as well 1821 as the archives of freebsd-current and freebsd-hackers mailing lists 1822 for potential gotchas. The -U option is also useful to consider. 1823 See mergemaster(8) for more information. 1824 1825 [5] Usually this step is a noop. However, from time to time 1826 you may need to do this if you get unknown user in the following 1827 step. It never hurts to do it all the time. You may need to 1828 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1829 install) after the buildworld before this step if you last updated 1830 from [78]-stable or 9-stable before 20130430. 1831 1832 [6] This only deletes old files and directories. Old libraries 1833 can be deleted by "make delete-old-libs", but you have to make 1834 sure that no program is using those libraries anymore. 1835 1836 [8] In order to have a kernel that can run the 4.x binaries needed to 1837 do an installworld, you must include the COMPAT_FREEBSD4 option in 1838 your kernel. Failure to do so may leave you with a system that is 1839 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1840 required to run the 5.x binaries on more recent kernels. And so on 1841 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1842 1843 Make sure that you merge any new devices from GENERIC since the 1844 last time you updated your kernel config file. 1845 1846 [9] When checking out sources, you must include the -P flag to have 1847 cvs prune empty directories. 1848 1849 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1850 "?=" instead of the "=" assignment operator, so that buildworld can 1851 override the CPUTYPE if it needs to. 1852 1853 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1854 not on the command line, or in /etc/make.conf. buildworld will 1855 warn if it is improperly defined. 1856FORMAT: 1857 1858This file contains a list, in reverse chronological order, of major 1859breakages in tracking -current. It is not guaranteed to be a complete 1860list of such breakages, and only contains entries since October 10, 2007. 1861If you need to see UPDATING entries from before that date, you will need 1862to fetch an UPDATING file from an older FreeBSD release. 1863 1864Copyright information: 1865 1866Copyright 1998-2009 M.
