[SA-14:18] 91 9220140716: 93 9.3-RELEASE. 94 9520140608: 96 On i386 and amd64 systems, the onifconsole flag is now set by default 97 in /etc/ttys for ttyu0. This causes ttyu0 to be automatically enabled 98 as a login TTY if it is set in the bootloader as an active kernel 99 console. No changes in behavior should result otherwise. To revert to 100 the previous behavior, set ttyu0 to "off" in /etc/ttys. 101 10220140512: 103 Clang and llvm have been upgraded to 3.4.1 release. 104 10520140321: 106 Clang and llvm have been upgraded to 3.4 release. 107 10820140216: 109 The nve(4) driver for NVIDIA nForce MCP Ethernet adapters has 110 been deprecated and will not be part of FreeBSD 11.0 and later 111 releases. If you use this driver, please consider switching to 112 the nfe(4) driver instead. 113 11420131216: 115 The behavior of gss_pseudo_random() for the krb5 mechanism 116 has changed, for applications requesting a longer random string 117 than produced by the underlying enctype's pseudo-random() function. 118 In particular, the random string produced from a session key of 119 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 120 be different at the 17th octet and later, after this change. 121 The counter used in the PRF+ construction is now encoded as a 122 big-endian integer in accordance with RFC 4402. 123 __FreeBSD_version is bumped to 902505. 124 12520130930: 126 9.2-RELEASE. 127 12820130823: 129 Behavior of devfs rules path matching has been changed. 130 Pattern is now always matched against fully qualified devfs 131 path and slash characters must be explicitly matched by 132 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 133 subdirectories must be reviewed. 134 13520130705: 136 hastctl(8)'s `status' command output changed to terse one-liner format. 137 Scripts using this should switch to `list' command or be rewritten. 138 13920130618: 140 Fix a bug that allowed a tracing process (e.g. gdb) to write 141 to a memory-mapped file in the traced process's address space 142 even if neither the traced process nor the tracing process had 143 write access to that file. 144 14520130605: 146 Added ZFS TRIM support which is enabled by default. To disable 147 ZFS TRIM support set vfs.zfs.trim.enabled=0 in loader.conf. 148 149 Creating new ZFS pools and adding new devices to existing pools 150 first performs a full device level TRIM which can take a significant 151 amount of time. The sysctl vfs.zfs.vdev.trim_on_init can be set to 0 152 to disable this behaviour. 153 154 ZFS TRIM requires the underlying device support BIO_DELETE which 155 is currently provided by methods such as ATA TRIM and SCSI UNMAP 156 via CAM, which are typically supported by SSD's. 157 158 Stats for ZFS TRIM can be monitored by looking at the sysctl's 159 under kstat.zfs.misc.zio_trim. 160 16120130524: 162 `list' command has been added to hastctl(8). For now, it is full 163 equivalent of `status' command. 164 WARNING: in the near future the output of hastctl's status command 165 will change to more terse format. If you use `hastctl status' 166 for parsing in your scripts, switch to `hastctl list'. 167 16820130430: 169 The mergemaster command now uses the default MAKEOBJDIRPREFIX 170 rather than creating it's own in the temporary directory in 171 order allow access to bootstrapped versions of tools such as 172 install and mtree. When upgrading from version of FreeBSD where 173 the install command does not support -l, you will need to 174 install a new mergemaster command if mergemaster -p is required. 175 This can be accomplished with the command (cd src/usr.sbin/mergemaster 176 && make install). 177 178 Due to the use of the new -l option to install(1) during build 179 and install, you must take care not to directly set the INSTALL 180 make variable in your /etc/make.conf, /etc/src.conf, or on the 181 command line. If you wish to use the -C flag for all installs 182 you may be able to add INSTALL+=-C to /etc/make.conf or 183 /etc/src.conf. 184 18520130429: 186 Fix a bug that allows NFS clients to issue READDIR on files. 187 18820130315: 189 The install(1) option -M has changed meaning and now takes an 190 argument that is a file or path to append logs to. In the 191 unlikely event that -M was the last option on the command line 192 and the command line contained at least two files and a target 193 directory the first file will have logs appended to it. The -M 194 option served little practical purpose in the last decade so it's 195 used expected to be extremely rare. 196 19720130225: 198 A new compression method (lz4) has been merged to. Please refer to 199 zpool-features(7) for more information. 200 201 Please refer to the "ZFS notes" section of this file for information 202 on upgrading boot ZFS pools. 203 20420121224: 205 The VFS KBI was changed with the merge of several nullfs 206 optimizations and fixes. All filesystem modules must be 207 recompiled. 208 20920121218: 210 With the addition of auditdistd(8), a new auditdistd user is now 211 depended on during installworld. "mergemaster -p" can be used to add 212 the user prior to installworld, as documented in the handbook. 213 21420121205: 215 9.1-RELEASE. 216 21720121129: 218 A new version of ZFS (pool version 5000) has been merged to 9-STABLE. 219 Starting with this version the old system of ZFS pool versioning 220 is superseded by "feature flags". This concept enables forward 221 compatibility against certain future changes in functionality of ZFS 222 pools. The first two read-only compatible "feature flags" for ZFS 223 pools are "com.delphix:async_destroy" and "com.delphix:empty_bpobj". 224 For more information read the new zpool-features(7) manual page. 225 Please refer to the "ZFS notes" section of this file for information 226 on upgrading boot ZFS pools. 227 22820121114: 229 The commit introducing bsd.compiler.mk breaks the traditional 230 building of kernels before this point. Add -m ${SRC}/share/mk 231 (for the right value of SRC) to your command lines to work 232 around; update your useland to a point after this; or use the 233 buildkernel/installkernel top-level targets. See also 20120829. 234 23520121102: 236 The IPFIREWALL_FORWARD kernel option has been removed. Its 237 functionality now turned on by default. 238 23920120913: 240 The random(4) support for the VIA hardware random number 241 generator (`PADLOCK') is no longer enabled unconditionally. 242 Add the PADLOCK_RNG option in the custom kernel config if 243 needed. The GENERIC kernels on i386 and amd64 do include the 244 option, so the change only affects the custom kernel 245 configurations. 246 24720120829: 248 The amd64 kernel now uses xsetbv, xrstor instructions. To compile with 249 the traditional method, you must update your system with an installworld 250 before the kernel will build. The documented make buildkernel/installkernel 251 interfaces (coupled with fresh make kernel-toolchain) continue to work. 252 25320120727: 254 The sparc64 ZFS loader has been changed to no longer try to auto- 255 detect ZFS providers based on diskN aliases but now requires these 256 to be explicitly listed in the OFW boot-device environment variable. 257 25820120422: 259 Now unix domain sockets behave "as expected" on nullfs(5). Previously 260 nullfs(5) did not pass through all behaviours to the underlying layer, 261 as a result if we bound to a socket on the lower layer we could connect 262 only to the lower path; if we bound to the upper layer we could connect 263 only to the upper path. The new behavior is one can connect to both the 264 lower and the upper paths regardless what layer path one binds to. 265 26620120109: 267 The acpi_wmi(4) status device /dev/wmistat has been renamed to 268 /dev/wmistat0. 269 27020120106: 271 A new VOP_ADVISE() was added to support posix_fadvise(2). All 272 filesystem modules must be recompiled. 273 27420120106: 275 The interface of the VOP_VPTOCNP(9) changed, now the returned 276 vnode shall be referenced, previously it was required to be 277 only held. All in-tree filesystems are converted. 278 27920120106: 280 9.0-RELEASE. 281 28220111101: 283 The broken amd(4) driver has been replaced with esp(4) in the amd64, 284 i386 and pc98 GENERIC kernel configuration files. 285 28620110913: 287 This commit modifies vfs_register() so that it uses a hash 288 calculation to set vfc_typenum, which is enabled by default. 289 The first time a system is booted after this change, the 290 vfc_typenum values will change for all file systems. The 291 main effect of this is a change to the NFS server file handles 292 for file systems that use vfc_typenum in their fsid, such as ZFS. 293 It will, however, prevent vfc_typenum from changing when file 294 systems are loaded in a different order for subsequent reboots. 295 To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf 296 until you are ready to remount all NFS clients after a reboot. 297 29820110828: 299 Bump the shared library version numbers for libraries that 300 do not use symbol versioning, have changed the ABI compared 301 to stable/8 and which shared library version was not bumped. 302 Done as part of 9.0-RELEASE cycle. 303 30420110815: 305 During the merge of Capsicum features, the fget(9) KPI was modified. 306 This may require the rebuilding of out-of-tree device drivers -- 307 issues have been reported specifically with the nVidia device driver. 308 __FreeBSD_version is bumped to 900041. 309 310 Also, there is a period between 20110811 and 20110814 where the 311 special devices /dev/{stdin,stdout,stderr} did not work correctly. 312 Building world from a kernel during that window may not work. 313 31420110628: 315 The packet filter (pf) code has been updated to OpenBSD 4.5. 316 You need to update userland tools to be in sync with kernel. 317 This update breaks backward compatibility with earlier pfsync(4) 318 versions. Care must be taken when updating redundant firewall setups. 319 32020110608: 321 The following sysctls and tunables are retired on x86 platforms: 322 machdep.hlt_cpus 323 machdep.hlt_logical_cpus 324 The following sysctl is retired: 325 machdep.hyperthreading_allowed 326 The sysctls were supposed to provide a way to dynamically offline and 327 online selected CPUs on x86 platforms, but the implementation has not 328 been reliable especially with SCHED_ULE scheduler. 329 machdep.hyperthreading_allowed tunable is still available to ignore 330 hyperthreading CPUs at OS level. 331 Individual CPUs can be disabled using hint.lapic.X.disabled tunable, 332 where X is an APIC ID of a CPU. Be advised, though, that disabling 333 CPUs in non-uniform fashion will result in non-uniform topology and 334 may lead to sub-optimal system performance with SCHED_ULE, which is 335 a default scheduler. 336 33720110607: 338 cpumask_t type is retired and cpuset_t is used in order to describe 339 a mask of CPUs. 340 34120110531: 342 Changes to ifconfig(8) for dynamic address family detection mandate 343 that you are running a kernel of 20110525 or later. Make sure to 344 follow the update procedure to boot a new kernel before installing 345 world. 346 34720110513: 348 Support for sun4v architecture is officially dropped 349 35020110503: 351 Several KPI breaking changes have been committed to the mii(4) layer, 352 the PHY drivers and consequently some Ethernet drivers using mii(4). 353 This means that miibus.ko and the modules of the affected Ethernet 354 drivers need to be recompiled. 355 356 Note to kernel developers: Given that the OUI bit reversion problem 357 was fixed as part of these changes all mii(4) commits related to OUIs, 358 i.e. to sys/dev/mii/miidevs, PHY driver probing and vendor specific 359 handling, no longer can be merged verbatim to stable/8 and previous 360 branches. 361 36220110430: 363 Users of the Atheros AR71xx SoC code now need to add 'device ar71xx_pci' 364 into their kernel configurations along with 'device pci'. 365 36620110427: 367 The default NFS client is now the new NFS client, so fstype "newnfs" 368 is now "nfs" and the regular/old NFS client is now fstype "oldnfs". 369 Although mounts via fstype "nfs" will usually work without userland 370 changes, it is recommended that the mount(8) and mount_nfs(8) 371 commands be rebuilt from sources and that a link to mount_nfs called 372 mount_oldnfs be created. The new client is compiled into the 373 kernel with "options NFSCL" and this is needed for diskless root 374 file systems. The GENERIC kernel configs have been changed to use 375 NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER. 376 To use the regular/old client, you can "mount -t oldnfs ...". For 377 a diskless root file system, you must also include a line like: 378 379 vfs.root.mountfrom="oldnfs:" 380 381 in the boot/loader.conf on the root fs on the NFS server to make 382 a diskless root fs use the old client. 383 38420110424: 385 The GENERIC kernels for all architectures now default to the new 386 CAM-based ATA stack. It means that all legacy ATA drivers were 387 removed and replaced by respective CAM drivers. If you are using 388 ATA device names in /etc/fstab or other places, make sure to update 389 them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY, 390 where 'Y's are the sequential numbers starting from zero for each type 391 in order of detection, unless configured otherwise with tunables, 392 see cam(4)). There will be symbolic links created in /dev/ to map 393 old adX devices to the respective adaY. They should provide basic 394 compatibility for file systems mounting in most cases, but they do 395 not support old user-level APIs and do not have respective providers 396 in GEOM. Consider using updated management tools with new device names. 397 398 It is possible to load devices ahci, ata, siis and mvs as modules, 399 but option ATA_CAM should remain in kernel configuration to make ata 400 module work as CAM driver supporting legacy ATA controllers. Device ata 401 still can be used in modular fashion (atacore + ...). Modules atadisk 402 and atapi* are not used and won't affect operation in ATA_CAM mode. 403 Note that to use CAM-based ATA kernel should include CAM devices 404 scbus, pass, da (or explicitly ada), cd and optionally others. All of 405 them are parts of the cam module. 406 407 ataraid(4) functionality is now supported by the RAID GEOM class. 408 To use it you can load geom_raid kernel module and use graid(8) tool 409 for management. Instead of /dev/arX device names, use /dev/raid/rX. 410 411 No kernel config options or code have been removed, so if a problem 412 arises, please report it and optionally revert to the old ATA stack. 413 In order to do it you can remove from the kernel config: 414 options ATA_CAM 415 device ahci 416 device mvs 417 device siis 418 , and instead add back: 419 device atadisk # ATA disk drives 420 device ataraid # ATA RAID drives 421 device atapicd # ATAPI CDROM drives 422 device atapifd # ATAPI floppy drives 423 device atapist # ATAPI tape drives 424 42520110423: 426 The default NFS server has been changed to the new server, which 427 was referred to as the experimental server. If you need to switch 428 back to the old NFS server, you must now put the "-o" option on 429 both the mountd and nfsd commands. This can be done using the 430 mountd_flags and nfs_server_flags rc.conf variables until an 431 update to the rc scripts is committed, which is coming soon. 432 43320110418: 434 The GNU Objective-C runtime library (libobjc), and other Objective-C 435 related components have been removed from the base system. If you 436 require an Objective-C library, please use one of the available ports. 437 43820110331: 439 ath(4) has been split into bus- and device- modules. if_ath contains 440 the HAL, the TX rate control and the network device code. if_ath_pci 441 contains the PCI bus glue. For Atheros MIPS embedded systems, if_ath_ahb 442 contains the AHB glue. Users need to load both if_ath_pci and if_ath 443 in order to use ath on everything else. 444 445 TO REPEAT: if_ath_ahb is not needed for normal users. Normal users only 446 need to load if_ath and if_ath_pci for ath(4) operation. 447 44820110314: 449 As part of the replacement of sysinstall, the process of building 450 release media has changed significantly. For details, please re-read 451 release(7), which has been updated to reflect the new build process. 452 45320110218: 454 GNU binutils 2.17.50 (as of 2007-07-03) has been merged to -HEAD. This 455 is the last available version under GPLv2. It brings a number of new 456 features, such as support for newer x86 CPU's (with SSE-3, SSSE-3, SSE 457 4.1 and SSE 4.2), better support for powerpc64, a number of new 458 directives, and lots of other small improvements. See the ChangeLog 459 file in contrib/binutils for the full details. 460 46120110218: 462 IPsec's HMAC_SHA256-512 support has been fixed to be RFC4868 463 compliant, and will now use half of hash for authentication. 464 This will break interoperability with all stacks (including all 465 actual FreeBSD versions) who implement 466 draft-ietf-ipsec-ciph-sha-256-00 (they use 96 bits of hash for 467 authentication). 468 The only workaround with such peers is to use another HMAC 469 algorithm for IPsec ("phase 2") authentication. 470 47120110207: 472 Remove the uio_yield prototype and symbol. This function has 473 been misnamed since it was introduced and should not be 474 globally exposed with this name. The equivalent functionality 475 is now available using kern_yield(curthread->td_user_pri). 476 The function remains undocumented. 477 47820110112: 479 A SYSCTL_[ADD_]UQUAD was added for unsigned uint64_t pointers, 480 symmetric with the existing SYSCTL_[ADD_]QUAD. Type checking 481 for scalar sysctls is defined but disabled. Code that needs 482 UQUAD to pass the type checking that must compile on older 483 systems where the define is not present can check against 484 __FreeBSD_version >= 900030. 485 486 The system dialog(1) has been replaced with a new version previously 487 in ports as devel/cdialog. dialog(1) is mostly command-line compatible 488 with the previous version, but the libdialog associated with it has 489 a largely incompatible API. As such, the original version of libdialog 490 will be kept temporarily as libodialog, until its base system consumers 491 are replaced or updated. Bump __FreeBSD_version to 900030. 492 49320110103: 494 If you are trying to run make universe on a -stable system, and you get 495 the following warning: 496 "Makefile", line 356: "Target architecture for i386/conf/GENERIC 497 unknown. config(8) likely too old." 498 or something similar to it, then you must upgrade your -stable system 499 to 8.2-Release or newer (really, any time after r210146 7/15/2010 in 500 stable/8) or build the config from the latest stable/8 branch and 501 install it on your system. 502 503 Prior to this date, building a current universe on 8-stable system from 504 between 7/15/2010 and 1/2/2011 would result in a weird shell parsing 505 error in the first kernel build phase. A new config on those old 506 systems will fix that problem for older versions of -current. 507 50820101228: 509 The TCP stack has been modified to allow Khelp modules to interact with 510 it via helper hook points and store per-connection data in the TCP 511 control block. Bump __FreeBSD_version to 900029. User space tools that 512 rely on the size of struct tcpcb in tcp_var.h (e.g. sockstat) need to 513 be recompiled. 514 51520101114: 516 Generic IEEE 802.3 annex 31B full duplex flow control support has been 517 added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along 518 with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted 519 to take advantage of it instead of using custom implementations. This 520 means that these drivers now no longer unconditionally advertise 521 support for flow control but only do so if flow control is a selected 522 media option. This was implemented in the generic support that way in 523 order to allow flow control to be switched on and off via ifconfig(8) 524 with the PHY specific default to typically off in order to protect 525 from unwanted effects. Consequently, if you used flow control with 526 one of the above mentioned drivers you now need to explicitly enable 527 it, for example via: 528 ifconfig bge0 media auto mediaopt flowcontrol 529 530 Along with the above mentioned changes generic support for setting 531 1000baseT master mode also has been added and brgphy(4), ciphy(4), 532 e1000phy(4) as well as ip1000phy(4) have been converted to take 533 advantage of it. This means that these drivers now no longer take the 534 link0 parameter for selecting master mode but the master media option 535 has to be used instead, for example like in the following: 536 ifconfig bge0 media 1000baseT mediaopt full-duplex,master 537 538 Selection of master mode now is also available with all other PHY 539 drivers supporting 1000baseT. 540 54120101111: 542 The TCP stack has received a significant update to add support for 543 modularised congestion control and generally improve the clarity of 544 congestion control decisions. Bump __FreeBSD_version to 900025. User 545 space tools that rely on the size of struct tcpcb in tcp_var.h (e.g. 546 sockstat) need to be recompiled. 547 54820101002: 549 The man(1) utility has been replaced by a new version that no longer 550 uses /etc/manpath.config. Please consult man.conf(5) for how to 551 migrate local entries to the new format. 552 55320100928: 554 The copyright strings printed by login(1) and sshd(8) at the time of a 555 new connection have been removed to follow other operating systems and 556 upstream sshd. 557 55820100915: 559 A workaround for a fixed ld bug has been removed in kernel code, 560 so make sure that your system ld is built from sources after 561 revision 210245 from 2010-07-19 (r211583 if building head kernel 562 on stable/8, r211584 for stable/7; both from 2010-08-21). 563 A symptom of incorrect ld version is different addresses for 564 set_pcpu section and __start_set_pcpu symbol in kernel and/or modules. 565 56620100913: 567 The $ipv6_prefer variable in rc.conf(5) has been split into 568 $ip6addrctl_policy and $ipv6_activate_all_interfaces. 569 570 The $ip6addrctl_policy is a variable to choose a pre-defined 571 address selection policy set by ip6addrctl(8). A value 572 "ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The 573 default is "AUTO". 574 575 The $ipv6_activate_all_interfaces specifies whether IFDISABLED 576 flag (see an entry of 20090926) is set on an interface with no 577 corresponding $ifconfig_IF_ipv6 line. The default is "NO" for 578 security reason. If you want IPv6 link-local address on all 579 interfaces by default, set this to "YES". 580 581 The old ipv6_prefer="YES" is equivalent to 582 ipv6_activate_all_interfaces="YES" and 583 ip6addrctl_policy="ipv6_prefer". 584 58520100913: 586 DTrace has grown support for userland tracing. Due to this, DTrace is 587 now i386 and amd64 only. 588 dtruss(1) is now installed by default on those systems and a new 589 kernel module is needed for userland tracing: fasttrap. 590 No changes to your kernel config file are necessary to enable 591 userland tracing, but you might consider adding 'STRIP=' and 592 'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want 593 to have informative userland stack traces in DTrace (ustack). 594 59520100725: 596 The acpi_aiboost(4) driver has been removed in favor of the new 597 aibs(4) driver. You should update your kernel configuration file. 598 59920100722: 600 BSD grep has been imported to the base system and it is built by 601 default. It is completely BSD licensed, highly GNU-compatible, uses 602 less memory than its GNU counterpart and has a small codebase. 603 However, it is slower than its GNU counterpart, which is mostly 604 noticeable for larger searches, for smaller ones it is measurable 605 but not significant. The reason is complex, the most important factor 606 is that we lack a modern and efficient regex library and GNU 607 overcomes this by optimizing the searches internally. Future work 608 on improving the regex performance is planned, for the meantime, 609 users that need better performance, can build GNU grep instead by 610 setting the WITH_GNU_GREP knob. 611 61220100713: 613 Due to the import of powerpc64 support, all existing powerpc kernel 614 configuration files must be updated with a machine directive like this: 615 machine powerpc powerpc 616 617 In addition, an updated config(8) is required to build powerpc kernels 618 after this change. 619 62020100713: 621 A new version of ZFS (version 15) has been merged to -HEAD. 622 This version uses a python library for the following subcommands: 623 zfs allow, zfs unallow, zfs groupspace, zfs userspace. 624 For full functionality of these commands the following port must 625 be installed: sysutils/py-zfs 626 62720100429: 628 'vm_page's are now hashed by physical address to an array of mutexes. 629 Currently this is only used to serialize access to hold_count. Over 630 time the page queue mutex will be peeled away. This changes the size 631 of pmap on every architecture. And requires all callers of vm_page_hold 632 and vm_page_unhold to be updated. 633 63420100402: 635 WITH_CTF can now be specified in src.conf (not recommended, there 636 are some problems with static executables), make.conf (would also 637 affect ports which do not use GNU make and do not override the 638 compile targets) or in the kernel config (via "makeoptions 639 WITH_CTF=yes"). 640 When WITH_CTF was specified there before this was silently ignored, 641 so make sure that WITH_CTF is not used in places which could lead 642 to unwanted behavior. 643 64420100311: 645 The kernel option COMPAT_IA32 has been replaced with COMPAT_FREEBSD32 646 to allow 32-bit compatibility on non-x86 platforms. All kernel 647 configurations on amd64 and ia64 platforms using these options must 648 be modified accordingly. 649 65020100113: 651 The utmp user accounting database has been replaced with utmpx, 652 the user accounting interface standardized by POSIX. 653 Unfortunately the semantics of utmp and utmpx don't match, 654 making it practically impossible to support both interfaces. 655 The user accounting database is used by tools like finger(1), 656 last(1), talk(1), w(1) and ac(8). 657 658 All applications in the base system use utmpx. This means only 659 local binaries (e.g. from the ports tree) may still use these 660 utmp database files. These applications must be rebuilt to make 661 use of utmpx. 662 663 After the system has been upgraded, it is safe to remove the old 664 log files (/var/run/utmp, /var/log/lastlog and /var/log/wtmp*), 665 assuming their contents is of no importance anymore. Old wtmp 666 databases can only be used by last(1) and ac(8) after they have 667 been converted to the new format using wtmpcvt(1). 668 66920100108: 670 Introduce the kernel thread "deadlock resolver" (which can be enabled 671 via the DEADLKRES option, see NOTES for more details) and the 672 sleepq_type() function for sleepqueues. 673 67420091202: 675 The rc.firewall and rc.firewall6 were unified, and 676 rc.firewall6 and rc.d/ip6fw were removed. 677 According to the removal of rc.d/ip6fw, ipv6_firewall_* rc 678 variables are obsoleted. Instead, the following new rc 679 variables are added to rc.d/ipfw: 680 681 firewall_client_net_ipv6, firewall_simple_iif_ipv6, 682 firewall_simple_inet_ipv6, firewall_simple_oif_ipv6, 683 firewall_simple_onet_ipv6, firewall_trusted_ipv6 684 685 The meanings correspond to the relevant IPv4 variables. 686 68720091125: 688 8.0-RELEASE. 689 69020091113: 691 The default terminal emulation for syscons(4) has been changed 692 from cons25 to xterm on all platforms except pc98. This means 693 that the /etc/ttys file needs to be updated to ensure correct 694 operation of applications on the console. 695 696 The terminal emulation style can be toggled per window by using 697 vidcontrol(1)'s -T flag. The TEKEN_CONS25 kernel configuration 698 options can be used to change the compile-time default back to 699 cons25. 700 701 To prevent graphical artifacts, make sure the TERM environment 702 variable is set to match the terminal emulation that is being 703 performed by syscons(4). 704 70520091109: 706 The layout of the structure ieee80211req_scan_result has changed. 707 Applications that require wireless scan results (e.g. ifconfig(8)) 708 from net80211 need to be recompiled. 709 710 Applications such as wpa_supplicant(8) may require a full world 711 build without using NO_CLEAN in order to get synchronized with the 712 new structure. 713 71420091025: 715 The iwn(4) driver has been updated to support the 5000 and 5150 series. 716 There's one kernel module for each firmware. Adding "device iwnfw" 717 to the kernel configuration file means including all three firmware 718 images inside the kernel. If you want to include just the one for 719 your wireless card, use the devices iwn4965fw, iwn5000fw or 720 iwn5150fw. 721 72220090926: 723 The rc.d/network_ipv6, IPv6 configuration script has been integrated 724 into rc.d/netif. The changes are the following: 725 726 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF 727 for IPv4. For aliases, $ifconfig_IF_aliasN should be used. 728 Note that both variables need the "inet6" keyword at the head. 729 730 Do not set $ipv6_network_interfaces manually if you do not 731 understand what you are doing. It is not needed in most cases. 732 733 $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but 734 they are obsolete. 735 736 2. $ipv6_enable is obsolete. Use $ipv6_prefer and 737 "inet6 accept_rtadv" keyword in ifconfig(8) instead. 738 739 If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and 740 all configured interfaces have "inet6 accept_rtadv" in the 741 $ifconfig_IF_ipv6. These are for backward compatibility. 742 743 3. A new variable $ipv6_prefer has been added. If NO, IPv6 744 functionality of interfaces with no corresponding 745 $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag, 746 and the default address selection policy of ip6addrctl(8) 747 is the IPv4-preferred one (see rc.d/ip6addrctl for more details). 748 Note that if you want to configure IPv6 functionality on the 749 disabled interfaces after boot, first you need to clear the flag by 750 using ifconfig(8) like: 751 752 ifconfig em0 inet6 -ifdisabled 753 754 If YES, the default address selection policy is set as 755 IPv6-preferred. 756 757 The default value of $ipv6_prefer is NO. 758 759 4. If your system need to receive Router Advertisement messages, 760 define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8) 761 scripts automatically invoke rtsol(8) when the interface becomes 762 UP. The Router Advertisement messages are used for SLAAC 763 (State-Less Address AutoConfiguration). 764 76520090922: 766 802.11s D3.03 support was committed. This is incompatible with the 767 previous code, which was based on D3.0. 768 76920090912: 770 A sysctl variable net.inet6.ip6.accept_rtadv now sets the default value 771 of a per-interface flag ND6_IFF_ACCEPT_RTADV, not a global knob to 772 control whether accepting Router Advertisement messages or not. 773 Also, a per-interface flag ND6_IFF_AUTO_LINKLOCAL has been added and 774 a sysctl variable net.inet6.ip6.auto_linklocal is its default value. 775 The ifconfig(8) utility now supports these flags. 776 77720090910: 778 ZFS snapshots are now mounted with MNT_IGNORE flag. Use -v option for 779 mount(8) and -a option for df(1) to see them. 780 78120090825: 782 The old tunable hw.bus.devctl_disable has been superseded by 783 hw.bus.devctl_queue. hw.bus.devctl_disable=1 in loader.conf should be 784 replaced by hw.bus.devctl_queue=0. The default for this new tunable 785 is 1000. 786 78720090813: 788 Remove the option STOP_NMI. The default action is now to use NMI only 789 for KDB via the newly introduced function stop_cpus_hard() and 790 maintain stop_cpus() to just use a normal IPI_STOP on ia32 and amd64. 791 79220090803: 793 The stable/8 branch created in subversion. This corresponds to the 794 RELENG_8 branch in CVS. 795 79620090719: 797 Bump the shared library version numbers for all libraries that do not 798 use symbol versioning as part of the 8.0-RELEASE cycle. Bump 799 __FreeBSD_version to 800105. 800 80120090714: 802 Due to changes in the implementation of virtual network stack support, 803 all network-related kernel modules must be recompiled. As this change 804 breaks the ABI, bump __FreeBSD_version to 800104. 805 80620090713: 807 The TOE interface to the TCP syncache has been modified to remove 808 struct tcpopt (<netinet/tcp_var.h>) from the ABI of the network stack. 809 The cxgb driver is the only TOE consumer affected by this change, and 810 needs to be recompiled along with the kernel. As this change breaks 811 the ABI, bump __FreeBSD_version to 800103. 812 81320090712: 814 Padding has been added to struct tcpcb, sackhint and tcpstat in 815 <netinet/tcp_var.h> to facilitate future MFCs and bug fixes whilst 816 maintaining the ABI. However, this change breaks the ABI, so bump 817 __FreeBSD_version to 800102. User space tools that rely on the size of 818 any of these structs (e.g. sockstat) need to be recompiled. 819 82020090630: 821 The NFS_LEGACYRPC option has been removed along with the old kernel 822 RPC implementation that this option selected. Kernel configurations 823 may need to be adjusted. 824 82520090629: 826 The network interface device nodes at /dev/net/<interface> have been 827 removed. All ioctl operations can be performed the normal way using 828 routing sockets. The kqueue functionality can generally be replaced 829 with routing sockets. 830 83120090628: 832 The documentation from the FreeBSD Documentation Project (Handbook, 833 FAQ, etc.) is now installed via packages by sysinstall(8) and under 834 the /usr/local/share/doc/freebsd directory instead of /usr/share/doc. 835 83620090624: 837 The ABI of various structures related to the SYSV IPC API have been 838 changed. As a result, the COMPAT_FREEBSD[456] and COMPAT_43 kernel 839 options now all require COMPAT_FREEBSD7. Bump __FreeBSD_version to 840 800100. 841 84220090622: 843 Layout of struct vnet has changed as routing related variables were 844 moved to their own Vimage module. Modules need to be recompiled. Bump 845 __FreeBSD_version to 800099. 846 84720090619: 848 NGROUPS_MAX and NGROUPS have been increased from 16 to 1023 and 1024 849 respectively. As long as no more than 16 groups per process are used, 850 no changes should be visible. When more than 16 groups are used, old 851 binaries may fail if they call getgroups() or getgrouplist() with 852 statically sized storage. Recompiling will work around this, but 853 applications should be modified to use dynamically allocated storage 854 for group arrays as POSIX.1-2008 does not cap an implementation's 855 number of supported groups at NGROUPS_MAX+1 as previous versions did. 856 857 NFS and portalfs mounts may also be affected as the list of groups is 858 truncated to 16. Users of NFS who use more than 16 groups, should 859 take care that negative group permissions are not used on the exported 860 file systems as they will not be reliable unless a GSSAPI based 861 authentication method is used. 862 86320090616: 864 The compiling option ADAPTIVE_LOCKMGRS has been introduced. This 865 option compiles in the support for adaptive spinning for lockmgrs 866 which want to enable it. The lockinit() function now accepts the flag 867 LK_ADAPTIVE in order to make the lock object subject to adaptive 868 spinning when both held in write and read mode. 869 87020090613: 871 The layout of the structure returned by IEEE80211_IOC_STA_INFO has 872 changed. User applications that use this ioctl need to be rebuilt. 873 87420090611: 875 The layout of struct thread has changed. Kernel and modules need to 876 be rebuilt. 877 87820090608: 879 The layout of structs ifnet, domain, protosw and vnet_net has changed. 880 Kernel modules need to be rebuilt. Bump __FreeBSD_version to 800097. 881 88220090602: 883 window(1) has been removed from the base system. It can now be 884 installed from ports. The port is called misc/window. 885 88620090601: 887 The way we are storing and accessing `routing table' entries has 888 changed. Programs reading the FIB, like netstat, need to be 889 re-compiled. 890 89120090601: 892 A new netisr implementation has been added for FreeBSD 8. Network 893 file system modules, such as igmp, ipdivert, and others, should be 894 rebuilt. 895 Bump __FreeBSD_version to 800096. 896 89720090530: 898 Remove the tunable/sysctl debug.mpsafevfs as its initial purpose is no 899 more valid. 900 90120090530: 902 Add VOP_ACCESSX(9). File system modules need to be rebuilt. 903 Bump __FreeBSD_version to 800094. 904 90520090529: 906 Add mnt_xflag field to 'struct mount'. File system modules need to be 907 rebuilt. 908 Bump __FreeBSD_version to 800093. 909 91020090528: 911 The compiling option ADAPTIVE_SX has been retired while it has been 912 introduced the option NO_ADAPTIVE_SX which handles the reversed logic. 913 The KPI for sx_init_flags() changes as accepting flags: 914 SX_ADAPTIVESPIN flag has been retired while the SX_NOADAPTIVE flag has 915 been introduced in order to handle the reversed logic. 916 Bump __FreeBSD_version to 800092. 917 91820090527: 919 Add support for hierarchical jails. Remove global securelevel. 920 Bump __FreeBSD_version to 800091. 921 92220090523: 923 The layout of struct vnet_net has changed, therefore modules 924 need to be rebuilt. 925 Bump __FreeBSD_version to 800090. 926 92720090523: 928 The newly imported zic(8) produces a new format in the output. Please 929 run tzsetup(8) to install the newly created data to /etc/localtime. 930 93120090520: 932 The sysctl tree for the usb stack has renamed from hw.usb2.* to 933 hw.usb.* and is now consistent again with previous releases. 934 93520090520: 936 802.11 monitor mode support was revised and driver api's were changed. 937 Drivers dependent on net80211 now support DLT_IEEE802_11_RADIO instead 938 of DLT_IEEE802_11. No user-visible data structures were changed but 939 applications that use DLT_IEEE802_11 may require changes. 940 Bump __FreeBSD_version to 800088. 941 94220090430: 943 The layout of the following structs has changed: sysctl_oid, 944 socket, ifnet, inpcbinfo, tcpcb, syncache_head, vnet_inet, 945 vnet_inet6 and vnet_ipfw. Most modules need to be rebuild or 946 panics may be experienced. World rebuild is required for 947 correctly checking networking state from userland. 948 Bump __FreeBSD_version to 800085. 949 95020090429: 951 MLDv2 and Source-Specific Multicast (SSM) have been merged 952 to the IPv6 stack. VIMAGE hooks are in but not yet used. 953 The implementation of SSM within FreeBSD's IPv6 stack closely 954 follows the IPv4 implementation. 955 956 For kernel developers: 957 958 * The most important changes are that the ip6_output() and 959 ip6_input() paths no longer take the IN6_MULTI_LOCK, 960 and this lock has been downgraded to a non-recursive mutex. 961 962 * As with the changes to the IPv4 stack to support SSM, filtering 963 of inbound multicast traffic must now be performed by transport 964 protocols within the IPv6 stack. This does not apply to TCP and 965 SCTP, however, it does apply to UDP in IPv6 and raw IPv6. 966 967 * The KPIs used by IPv6 multicast are similar to those used by 968 the IPv4 stack, with the following differences: 969 * im6o_mc_filter() is analogous to imo_multicast_filter(). 970 * The legacy KAME entry points in6_joingroup and in6_leavegroup() 971 are shimmed to in6_mc_join() and in6_mc_leave() respectively. 972 * IN6_LOOKUP_MULTI() has been deprecated and removed. 973 * IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs 974 for MLDv1 have an additional 'timer' argument which is used to 975 jitter the initial membership report for the solicited-node 976 multicast membership on-link. 977 * This is not strictly needed for MLDv2, which already jitters 978 its report transmissions. However, the 'timer' argument is 979 preserved in case MLDv1 is active on the interface. 980 981 * The KAME linked-list based IPv6 membership implementation has 982 been refactored to use a vector similar to that used by the IPv4 983 stack. 984 Code which maintains a list of its own multicast memberships 985 internally, e.g. carp, has been updated to reflect the new 986 semantics. 987 988 * There is a known Lock Order Reversal (LOR) due to in6_setscope() 989 acquiring the IF_AFDATA_LOCK and being called within ip6_output(). 990 Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an 991 implementation constraint which needs to be addressed in HEAD. 992 993 For application developers: 994 995 * The changes are broadly similar to those made for the IPv4 996 stack. 997 998 * The use of IPv4 and IPv6 multicast socket options on the same 999 socket, using mapped addresses, HAS NOT been tested or supported. 1000 1001 * There are a number of issues with the implementation of various 1002 IPv6 multicast APIs which need to be resolved in the API surface 1003 before the implementation is fully compatible with KAME userland 1004 use, and these are mostly to do with interface index treatment. 1005 1006 * The literature available discusses the use of either the delta / ASM 1007 API with setsockopt(2)/getsockopt(2), or the full-state / ASM API 1008 using setsourcefilter(3)/getsourcefilter(3). For more information 1009 please refer to RFC 3768, 'Socket Interface Extensions for 1010 Multicast Source Filters'. 1011 1012 * Applications which use the published RFC 3678 APIs should be fine. 1013 1014 For systems administrators: 1015 1016 * The mtest(8) utility has been refactored to support IPv6, in 1017 addition to IPv4. Interface addresses are no longer accepted 1018 as arguments, their names must be used instead. The utility 1019 will map the interface name to its first IPv4 address as 1020 returned by getifaddrs(3). 1021 1022 * The ifmcstat(8) utility has also been updated to print the MLDv2 1023 endpoint state and source filter lists via sysctl(3). 1024 1025 * The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable 1026 loopback of IPv6 multicast datagrams by default; it defaults to 1 1027 to preserve the existing behaviour. Disabling multicast loopback is 1028 recommended for optimal system performance. 1029 1030 * The IPv6 MROUTING code has been changed to examine this sysctl 1031 instead of attempting to perform a group lookup before looping 1032 back forwarded datagrams. 1033 1034 Bump __FreeBSD_version to 800084. 1035 103620090422: 1037 Implement low-level Bluetooth HCI API. 1038 Bump __FreeBSD_version to 800083. 1039 104020090419: 1041 The layout of struct malloc_type, used by modules to register new 1042 memory allocation types, has changed. Most modules will need to 1043 be rebuilt or panics may be experienced. 1044 Bump __FreeBSD_version to 800081. 1045 104620090415: 1047 Anticipate overflowing inp_flags - add inp_flags2. 1048 This changes most offsets in inpcb, so checking v4 connection 1049 state will require a world rebuild. 1050 Bump __FreeBSD_version to 800080. 1051 105220090415: 1053 Add an llentry to struct route and struct route_in6. Modules 1054 embedding a struct route will need to be recompiled. 1055 Bump __FreeBSD_version to 800079. 1056 105720090414: 1058 The size of rt_metrics_lite and by extension rtentry has changed. 1059 Networking administration apps will need to be recompiled. 1060 The route command now supports show as an alias for get, weighting 1061 of routes, sticky and nostick flags to alter the behavior of stateful 1062 load balancing. 1063 Bump __FreeBSD_version to 800078. 1064 106520090408: 1066 Do not use Giant for kbdmux(4) locking. This is wrong and 1067 apparently causing more problems than it solves. This will 1068 re-open the issue where interrupt handlers may race with 1069 kbdmux(4) in polling mode. Typical symptoms include (but 1070 not limited to) duplicated and/or missing characters when 1071 low level console functions (such as gets) are used while 1072 interrupts are enabled (for example geli password prompt, 1073 mountroot prompt etc.). Disabling kbdmux(4) may help. 1074 107520090407: 1076 The size of structs vnet_net, vnet_inet and vnet_ipfw has changed; 1077 kernel modules referencing any of the above need to be recompiled. 1078 Bump __FreeBSD_version to 800075. 1079 108020090320: 1081 GEOM_PART has become the default partition slicer for storage devices, 1082 replacing GEOM_MBR, GEOM_BSD, GEOM_PC98 and GEOM_GPT slicers. It 1083 introduces some changes: 1084 1085 MSDOS/EBR: the devices created from MSDOS extended partition entries 1086 (EBR) can be named differently than with GEOM_MBR and are now symlinks 1087 to devices with offset-based names. fstabs may need to be modified. 1088 1089 BSD: the "geometry does not match label" warning is harmless in most 1090 cases but it points to problems in file system misalignment with 1091 disk geometry. The "c" partition is now implicit, covers the whole 1092 top-level drive and cannot be (mis)used by users. 1093 1094 General: Kernel dumps are now not allowed to be written to devices 1095 whose partition types indicate they are meant to be used for file 1096 systems (or, in case of MSDOS partitions, as something else than 1097 the "386BSD" type). 1098 1099 Most of these changes date approximately from 200812. 1100 110120090319: 1102 The uscanner(4) driver has been removed from the kernel. This follows 1103 Linux removing theirs in 2.6 and making libusb the default interface 1104 (supported by sane). 1105 110620090319: 1107 The multicast forwarding code has been cleaned up. netstat(1) 1108 only relies on KVM now for printing bandwidth upcall meters. 1109 The IPv4 and IPv6 modules are split into ip_mroute_mod and 1110 ip6_mroute_mod respectively. The config(5) options for statically 1111 compiling this code remain the same, i.e. 'options MROUTING'. 1112 111320090315: 1114 Support for the IFF_NEEDSGIANT network interface flag has been 1115 removed, which means that non-MPSAFE network device drivers are no 1116 longer supported. In particular, if_ar, if_sr, and network device 1117 drivers from the old (legacy) USB stack can no longer be built or 1118 used. 1119 112020090313: 1121 POSIX.1 Native Language Support (NLS) has been enabled in libc and 1122 a bunch of new language catalog files have also been added. 1123 This means that some common libc messages are now localized and 1124 they depend on the LC_MESSAGES environmental variable. 1125 112620090313: 1127 The k8temp(4) driver has been renamed to amdtemp(4) since 1128 support for Family 10 and Family 11 CPU families was added. 1129 113020090309: 1131 IGMPv3 and Source-Specific Multicast (SSM) have been merged 1132 to the IPv4 stack. VIMAGE hooks are in but not yet used. 1133 1134 For kernel developers, the most important changes are that the 1135 ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(), 1136 and this lock has been downgraded to a non-recursive mutex. 1137 1138 Transport protocols (UDP, Raw IP) are now responsible for filtering 1139 inbound multicast traffic according to group membership and source 1140 filters. The imo_multicast_filter() KPI exists for this purpose. 1141 Transports which do not use multicast (SCTP, TCP) already reject 1142 multicast by default. Forwarding and receive performance may improve 1143 as a mutex acquisition is no longer needed in the ip_input() 1144 low-level input path. in_addmulti() and in_delmulti() are shimmed 1145 to new KPIs which exist to support SSM in-kernel. 1146 1147 For application developers, it is recommended that loopback of 1148 multicast datagrams be disabled for best performance, as this 1149 will still cause the lock to be taken for each looped-back 1150 datagram transmission. The net.inet.ip.mcast.loop sysctl may 1151 be tuned to 0 to disable loopback by default; it defaults to 1 1152 to preserve the existing behaviour. 1153 1154 For systems administrators, to obtain best performance with 1155 multicast reception and multiple groups, it is always recommended 1156 that a card with a suitably precise hash filter is used. Hash 1157 collisions will still result in the lock being taken within the 1158 transport protocol input path to check group membership. 1159 1160 If deploying FreeBSD in an environment with IGMP snooping switches, 1161 it is recommended that the net.inet.igmp.sendlocal sysctl remain 1162 enabled; this forces 224.0.0.0/24 group membership to be announced 1163 via IGMP. 1164 1165 The size of 'struct igmpstat' has changed; netstat needs to be 1166 recompiled to reflect this. 1167 Bump __FreeBSD_version to 800070. 1168 116920090309: 1170 libusb20.so.1 is now installed as libusb.so.1 and the ports system 1171 updated to use it. This requires a buildworld/installworld in order to 1172 update the library and dependencies (usbconfig, etc). Its advisable to 1173 rebuild all ports which uses libusb. More specific directions are given 1174 in the ports collection UPDATING file. Any /etc/libmap.conf entries for 1175 libusb are no longer required and can be removed. 1176 117720090302: 1178 A workaround is committed to allow the creation of System V shared 1179 memory segment of size > 2 GB on the 64-bit architectures. 1180 Due to a limitation of the existing ABI, the shm_segsz member 1181 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is 1182 wrong for large segments. Note that limits must be explicitly 1183 raised to allow such segments to be created. 1184 118520090301: 1186 The layout of struct ifnet has changed, requiring a rebuild of all 1187 network device driver modules. 1188 118920090227: 1190 The /dev handling for the new USB stack has changed, a 1191 buildworld/installworld is required for libusb20. 1192 119320090223: 1194 The new USB2 stack has now been permanently moved in and all kernel and 1195 module names reverted to their previous values (eg, usb, ehci, ohci, 1196 ums, ...). The old usb stack can be compiled in by prefixing the name 1197 with the letter 'o', the old usb modules have been removed. 1198 Updating entry 20090216 for xorg and 20090215 for libmap may still 1199 apply. 1200 120120090217: 1202 The rc.conf(5) option if_up_delay has been renamed to 1203 defaultroute_delay to better reflect its purpose. If you have 1204 customized this setting in /etc/rc.conf you need to update it to 1205 use the new name. 1206 120720090216: 1208 xorg 7.4 wants to configure its input devices via hald which does not 1209 yet work with USB2. If the keyboard/mouse does not work in xorg then 1210 add 1211 Option "AllowEmptyInput" "off" 1212 to your ServerLayout section. This will cause X to use the configured 1213 kbd and mouse sections from your xorg.conf. 1214 121520090215: 1216 The GENERIC kernels for all architectures now default to the new USB2 1217 stack. No kernel config options or code have been removed so if a 1218 problem arises please report it and optionally revert to the old USB 1219 stack. If you are loading USB kernel modules or have a custom kernel 1220 that includes GENERIC then ensure that usb names are also changed over, 1221 eg uftdi -> usb2_serial_ftdi. 1222 1223 Older programs linked against the ports libusb 0.1 need to be 1224 redirected to the new stack's libusb20. /etc/libmap.conf can 1225 be used for this: 1226 # Map old usb library to new one for usb2 stack 1227 libusb-0.1.so.8 libusb20.so.1 1228 122920090209: 1230 All USB ethernet devices now attach as interfaces under the name ueN 1231 (eg. ue0). This is to provide a predictable name as vendors often 1232 change usb chipsets in a product without notice. 1233 123420090203: 1235 The ichsmb(4) driver has been changed to require SMBus slave 1236 addresses be left-justified (xxxxxxx0b) rather than right-justified. 1237 All of the other SMBus controller drivers require left-justified 1238 slave addresses, so this change makes all the drivers provide the 1239 same interface. 1240 124120090201: 1242 INET6 statistics (struct ip6stat) was updated. 1243 netstat(1) needs to be recompiled. 1244 124520090119: 1246 NTFS has been removed from GENERIC kernel on amd64 to match 1247 GENERIC on i386. Should not cause any issues since mount_ntfs(8) 1248 will load ntfs.ko module automatically when NTFS support is 1249 actually needed, unless ntfs.ko is not installed or security 1250 level prohibits loading kernel modules. If either is the case, 1251 "options NTFS" has to be added into kernel config. 1252 125320090115: 1254 TCP Appropriate Byte Counting (RFC 3465) support added to kernel. 1255 New field in struct tcpcb breaks ABI, so bump __FreeBSD_version to 1256 800061. User space tools that rely on the size of struct tcpcb in 1257 tcp_var.h (e.g. sockstat) need to be recompiled. 1258 125920081225: 1260 ng_tty(4) module updated to match the new TTY subsystem. 1261 Due to API change, user-level applications must be updated. 1262 New API support added to mpd5 CVS and expected to be present 1263 in next mpd5.3 release. 1264 126520081219: 1266 With __FreeBSD_version 800060 the makefs tool is part of 1267 the base system (it was a port). 1268 126920081216: 1270 The afdata and ifnet locks have been changed from mutexes to 1271 rwlocks, network modules will need to be re-compiled. 1272 127320081214: 1274 __FreeBSD_version 800059 incorporates the new arp-v2 rewrite. 1275 RTF_CLONING, RTF_LLINFO and RTF_WASCLONED flags are eliminated. 1276 The new code reduced struct rtentry{} by 16 bytes on 32-bit 1277 architecture and 40 bytes on 64-bit architecture. The userland 1278 applications "arp" and "ndp" have been updated accordingly. 1279 The output from "netstat -r" shows only routing entries and 1280 none of the L2 information. 1281 128220081130: 1283 __FreeBSD_version 800057 marks the switchover from the 1284 binary ath hal to source code. Users must add the line: 1285 1286 options AH_SUPPORT_AR5416 1287 1288 to their kernel config files when specifying: 1289 1290 device ath_hal 1291 1292 The ath_hal module no longer exists; the code is now compiled 1293 together with the driver in the ath module. It is now 1294 possible to tailor chip support (i.e. reduce the set of chips 1295 and thereby the code size); consult ath_hal(4) for details. 1296 129720081121: 1298 __FreeBSD_version 800054 adds memory barriers to 1299 <machine/atomic.h>, new interfaces to ifnet to facilitate 1300 multiple hardware transmit queues for cards that support 1301 them, and a lock-less ring-buffer implementation to 1302 enable drivers to more efficiently manage queueing of 1303 packets. 1304 130520081117: 1306 A new version of ZFS (version 13) has been merged to -HEAD. 1307 This version has zpool attribute "listsnapshots" off by 1308 default, which means "zfs list" does not show snapshots, 1309 and is the same as Solaris behavior. 1310 131120081028: 1312 dummynet(4) ABI has changed. ipfw(8) needs to be recompiled. 1313 131420081009: 1315 The uhci, ohci, ehci and slhci USB Host controller drivers have 1316 been put into separate modules. If you load the usb module 1317 separately through loader.conf you will need to load the 1318 appropriate *hci module as well. E.g. for a UHCI-based USB 2.0 1319 controller add the following to loader.conf: 1320 1321 uhci_load="YES" 1322 ehci_load="YES" 1323 132420081009: 1325 The ABI used by the PMC toolset has changed. Please keep 1326 userland (libpmc(3)) and the kernel module (hwpmc(4)) in 1327 sync. 1328 132920081009: 1330 atapci kernel module now includes only generic PCI ATA 1331 driver. AHCI driver moved to ataahci kernel module. 1332 All vendor-specific code moved into separate kernel modules: 1333 ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, 1334 atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, 1335 atamarvell, atamicron, atanational, atanetcell, atanvidia, 1336 atapromise, ataserverworks, atasiliconimage, atasis, atavia 1337 133820080820: 1339 The TTY subsystem of the kernel has been replaced by a new 1340 implementation, which provides better scalability and an 1341 improved driver model. Most common drivers have been migrated to 1342 the new TTY subsystem, while others have not. The following 1343 drivers have not yet been ported to the new TTY layer: 1344 1345 PCI/ISA: 1346 cy, digi, rc, rp, sio 1347 1348 USB: 1349 ubser, ucycom 1350 1351 Line disciplines: 1352 ng_h4, ng_tty, ppp, sl, snp 1353 1354 Adding these drivers to your kernel configuration file shall 1355 cause compilation to fail. 1356 135720080818: 1358 ntpd has been upgraded to 4.2.4p5. 1359 136020080801: 1361 OpenSSH has been upgraded to 5.1p1. 1362 1363 For many years, FreeBSD's version of OpenSSH preferred DSA 1364 over RSA for host and user authentication keys. With this 1365 upgrade, we've switched to the vendor's default of RSA over 1366 DSA. This may cause upgraded clients to warn about unknown 1367 host keys even for previously known hosts. Users should 1368 follow the usual procedure for verifying host keys before 1369 accepting the RSA key. 1370 1371 This can be circumvented by setting the "HostKeyAlgorithms" 1372 option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh 1373 command line. 1374 1375 Please note that the sequence of keys offered for 1376 authentication has been changed as well. You may want to 1377 specify IdentityFile in a different order to revert this 1378 behavior. 1379 138020080713: 1381 The sio(4) driver has been removed from the i386 and amd64 1382 kernel configuration files. This means uart(4) is now the 1383 default serial port driver on those platforms as well. 1384 1385 To prevent collisions with the sio(4) driver, the uart(4) driver 1386 uses different names for its device nodes. This means the 1387 onboard serial port will now most likely be called "ttyu0" 1388 instead of "ttyd0". You may need to reconfigure applications to 1389 use the new device names. 1390 1391 When using the serial port as a boot console, be sure to update 1392 /boot/device.hints and /etc/ttys before booting the new kernel. 1393 If you forget to do so, you can still manually specify the hints 1394 at the loader prompt: 1395 1396 set hint.uart.0.at="isa" 1397 set hint.uart.0.port="0x3F8" 1398 set hint.uart.0.flags="0x10" 1399 set hint.uart.0.irq="4" 1400 boot -s 1401 140220080609: 1403 The gpt(8) utility has been removed. Use gpart(8) to partition 1404 disks instead. 1405 140620080603: 1407 The version that Linuxulator emulates was changed from 2.4.2 1408 to 2.6.16. If you experience any problems with Linux binaries 1409 please try to set sysctl compat.linux.osrelease to 2.4.2 and 1410 if it fixes the problem contact emulation mailing list. 1411 141220080525: 1413 ISDN4BSD (I4B) was removed from the src tree. You may need to 1414 update a your kernel configuration and remove relevant entries. 1415 141620080509: 1417 I have checked in code to support multiple routing tables. 1418 See the man pages setfib(1) and setfib(2). 1419 This is a hopefully backwards compatible version, 1420 but to make use of it you need to compile your kernel 1421 with options ROUTETABLES=2 (or more up to 16). 1422 142320080420: 1424 The 802.11 wireless support was redone to enable multi-bss 1425 operation on devices that are capable. The underlying device 1426 is no longer used directly but instead wlanX devices are 1427 cloned with ifconfig. This requires changes to rc.conf files. 1428 For example, change: 1429 ifconfig_ath0="WPA DHCP" 1430 to 1431 wlans_ath0=wlan0 1432 ifconfig_wlan0="WPA DHCP" 1433 see rc.conf(5) for more details. In addition, mergemaster of 1434 /etc/rc.d is highly recommended. Simultaneous update of userland 1435 and kernel wouldn't hurt either. 1436 1437 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta 1438 modules were merged into the base wlan module. All references 1439 to these modules (e.g. in kernel config files) must be removed. 1440 144120080408: 1442 psm(4) has gained write(2) support in native operation level. 1443 Arbitrary commands can be written to /dev/psm%d and status can 1444 be read back from it. Therefore, an application is responsible 1445 for status validation and error recovery. It is a no-op in 1446 other operation levels. 1447 144820080312: 1449 Support for KSE threading has been removed from the kernel. To 1450 run legacy applications linked against KSE libmap.conf may 1451 be used. The following libmap.conf may be used to ensure 1452 compatibility with any prior release: 1453 1454 libpthread.so.1 libthr.so.1 1455 libpthread.so.2 libthr.so.2 1456 libkse.so.3 libthr.so.3 1457 145820080301: 1459 The layout of struct vmspace has changed. This affects libkvm 1460 and any executables that link against libkvm and use the 1461 kvm_getprocs() function. In particular, but not exclusively, 1462 it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1). 1463 The effects are minimal, but it's advisable to upgrade world 1464 nonetheless. 1465 146620080229: 1467 The latest em driver no longer has support in it for the 1468 82575 adapter, this is now moved to the igb driver. The 1469 split was done to make new features that are incompatible 1470 with older hardware easier to do. 1471 147220080220: 1473 The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4), 1474 likewise the kernel option is now GEOM_LINUX_LVM. 1475 147620080211: 1477 The default NFS mount mode has changed from UDP to TCP for 1478 increased reliability. If you rely on (insecurely) NFS 1479 mounting across a firewall you may need to update your 1480 firewall rules. 1481 148220080208: 1483 Belatedly note the addition of m_collapse for compacting 1484 mbuf chains. 1485 148620080126: 1487 The fts(3) structures have been changed to use adequate 1488 integer types for their members and so to be able to cope 1489 with huge file trees. The old fts(3) ABI is preserved 1490 through symbol versioning in libc, so third-party binaries 1491 using fts(3) should still work, although they will not take 1492 advantage of the extended types. At the same time, some 1493 third-party software might fail to build after this change 1494 due to unportable assumptions made in its source code about 1495 fts(3) structure members. Such software should be fixed 1496 by its vendor or, in the worst case, in the ports tree. 1497 FreeBSD_version 800015 marks this change for the unlikely 1498 case that a portable fix is impossible. 1499 150020080123: 1501 To upgrade to -current after this date, you must be running 1502 FreeBSD not older than 6.0-RELEASE. Upgrading to -current 1503 from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems. 1504 150520071128: 1506 The ADAPTIVE_GIANT kernel option has been retired because its 1507 functionality is the default now. 1508 150920071118: 1510 The AT keyboard emulation of sunkbd(4) has been turned on 1511 by default. In order to make the special symbols of the Sun 1512 keyboards driven by sunkbd(4) work under X these now have 1513 to be configured the same way as Sun USB keyboards driven 1514 by ukbd(4) (which also does AT keyboard emulation), f.e.: 1515 1516 Option "XkbLayout" "us" 1517 Option "XkbRules" "xorg" 1518 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 1519 152020071024: 1521 It has been decided that it is desirable to provide ABI 1522 backwards compatibility to the FreeBSD 4/5/6 versions of the 1523 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 1524 broken with the introduction of PCI domain support (see the 1525 20070930 entry). Unfortunately, this required the ABI of 1526 PCIOCGETCONF to be broken again in order to be able to 1527 provide backwards compatibility to the old version of that 1528 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 1529 again. As for prominent ports this affects neither pciutils 1530 nor xorg-server this time, the hal port needs to be rebuilt 1531 however. 1532 153320071020: 1534 The misnamed kthread_create() and friends have been renamed 1535 to kproc_create() etc. Many of the callers already 1536 used kproc_start().. 1537 I will return kthread_create() and friends in a while 1538 with implementations that actually create threads, not procs. 1539 Renaming corresponds with version 800002. 1540 154120071010: 1542 RELENG_7 branched. 1543 1544COMMON ITEMS: 1545 1546 General Notes 1547 ------------- 1548 Avoid using make -j when upgrading. While generally safe, there are 1549 sometimes problems using -j to upgrade. If your upgrade fails with 1550 -j, please try again without -j. From time to time in the past there 1551 have been problems using -j with buildworld and/or installworld. This 1552 is especially true when upgrading between "distant" versions (eg one 1553 that cross a major release boundary or several minor releases, or when 1554 several months have passed on the -current branch). 1555 1556 Sometimes, obscure build problems are the result of environment 1557 poisoning. This can happen because the make utility reads its 1558 environment when searching for values for global variables. To run 1559 your build attempts in an "environmental clean room", prefix all make 1560 commands with 'env -i '. See the env(1) manual page for more details. 1561 1562 When upgrading from one major version to another it is generally best 1563 to upgrade to the latest code in the currently installed branch first, 1564 then do an upgrade to the new branch. This is the best-tested upgrade 1565 path, and has the highest probability of being successful. Please try 1566 this approach before reporting problems with a major version upgrade. 1567 1568 ZFS notes 1569 --------- 1570 When upgrading the boot ZFS pool to a new version, always follow 1571 these two steps: 1572 1573 1.) recompile and reinstall the ZFS boot loader and boot block 1574 (this is part of "make buildworld" and "make installworld") 1575 1576 2.) update the ZFS boot block on your boot drive 1577 1578 The following example updates the ZFS boot block on the first 1579 partition (freebsd-boot) of a GPT partitioned drive ad0: 1580 "gpart bootcode -p /boot/gptzfsboot -i 1 ad0" 1581 1582 Non-boot pools do not need these updates. 1583 1584 To build a kernel 1585 ----------------- 1586 If you are updating from a prior version of FreeBSD (even one just 1587 a few days old), you should follow this procedure. It is the most 1588 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1589 1590 make kernel-toolchain 1591 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1592 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1593 1594 To test a kernel once 1595 --------------------- 1596 If you just want to boot a kernel once (because you are not sure 1597 if it works, or if you want to boot a known bad kernel to provide 1598 debugging information) run 1599 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1600 nextboot -k testkernel 1601 1602 To just build a kernel when you know that it won't mess you up 1603 -------------------------------------------------------------- 1604 This assumes you are already running a CURRENT system. Replace 1605 ${arch} with the architecture of your machine (e.g. "i386", 1606 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1607 1608 cd src/sys/${arch}/conf 1609 config KERNEL_NAME_HERE 1610 cd ../compile/KERNEL_NAME_HERE 1611 make depend 1612 make 1613 make install 1614 1615 If this fails, go to the "To build a kernel" section. 1616 1617 To rebuild everything and install it on the current system. 1618 ----------------------------------------------------------- 1619 # Note: sometimes if you are running current you gotta do more than 1620 # is listed here if you are upgrading from a really old current. 1621 1622 <make sure you have good level 0 dumps> 1623 make buildworld 1624 make kernel KERNCONF=YOUR_KERNEL_HERE 1625 [1] 1626 <reboot in single user> [3] 1627 mergemaster -p [5] 1628 make installworld 1629 mergemaster -i [4] 1630 make delete-old [6] 1631 <reboot> 1632 1633 1634 To cross-install current onto a separate partition 1635 -------------------------------------------------- 1636 # In this approach we use a separate partition to hold 1637 # current's root, 'usr', and 'var' directories. A partition 1638 # holding "/", "/usr" and "/var" should be about 2GB in 1639 # size. 1640 1641 <make sure you have good level 0 dumps> 1642 <boot into -stable> 1643 make buildworld 1644 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1645 <maybe newfs current's root partition> 1646 <mount current's root partition on directory ${CURRENT_ROOT}> 1647 make installworld DESTDIR=${CURRENT_ROOT} 1648 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1649 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1650 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1651 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1652 <reboot into current> 1653 <do a "native" rebuild/install as described in the previous section> 1654 <maybe install compatibility libraries from ports/misc/compat*> 1655 <reboot> 1656 1657 1658 To upgrade in-place from stable to current 1659 ---------------------------------------------- 1660 <make sure you have good level 0 dumps> 1661 make buildworld [9] 1662 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1663 [1] 1664 <reboot in single user> [3] 1665 mergemaster -p [5] 1666 make installworld 1667 mergemaster -i [4] 1668 make delete-old [6] 1669 <reboot> 1670 1671 Make sure that you've read the UPDATING file to understand the 1672 tweaks to various things you need. At this point in the life 1673 cycle of current, things change often and you are on your own 1674 to cope. The defaults can also change, so please read ALL of 1675 the UPDATING entries. 1676 1677 Also, if you are tracking -current, you must be subscribed to 1678 freebsd-current@freebsd.org. Make sure that before you update 1679 your sources that you have read and understood all the recent 1680 messages there. If in doubt, please track -stable which has 1681 much fewer pitfalls. 1682 1683 [1] If you have third party modules, such as vmware, you 1684 should disable them at this point so they don't crash your 1685 system on reboot. 1686 1687 [3] From the bootblocks, boot -s, and then do 1688 fsck -p 1689 mount -u / 1690 mount -a 1691 cd src 1692 adjkerntz -i # if CMOS is wall time 1693 Also, when doing a major release upgrade, it is required that 1694 you boot into single user mode to do the installworld. 1695 1696 [4] Note: This step is non-optional. Failure to do this step 1697 can result in a significant reduction in the functionality of the 1698 system. Attempting to do it by hand is not recommended and those 1699 that pursue this avenue should read this file carefully, as well 1700 as the archives of freebsd-current and freebsd-hackers mailing lists 1701 for potential gotchas. The -U option is also useful to consider. 1702 See mergemaster(8) for more information. 1703 1704 [5] Usually this step is a noop. However, from time to time 1705 you may need to do this if you get unknown user in the following 1706 step. It never hurts to do it all the time. You may need to 1707 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1708 install) after the buildworld before this step if you last updated 1709 from [78]-stable or 9-stable before 20130430. 1710 1711 [6] This only deletes old files and directories. Old libraries 1712 can be deleted by "make delete-old-libs", but you have to make 1713 sure that no program is using those libraries anymore. 1714 1715 [8] In order to have a kernel that can run the 4.x binaries needed to 1716 do an installworld, you must include the COMPAT_FREEBSD4 option in 1717 your kernel. Failure to do so may leave you with a system that is 1718 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1719 required to run the 5.x binaries on more recent kernels. And so on 1720 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1721 1722 Make sure that you merge any new devices from GENERIC since the 1723 last time you updated your kernel config file. 1724 1725 [9] When checking out sources, you must include the -P flag to have 1726 cvs prune empty directories. 1727 1728 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1729 "?=" instead of the "=" assignment operator, so that buildworld can 1730 override the CPUTYPE if it needs to. 1731 1732 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1733 not on the command line, or in /etc/make.conf. buildworld will 1734 warn if it is improperly defined. 1735FORMAT: 1736 1737This file contains a list, in reverse chronological order, of major 1738breakages in tracking -current. It is not guaranteed to be a complete 1739list of such breakages, and only contains entries since October 10, 2007. 1740If you need to see UPDATING entries from before that date, you will need 1741to fetch an UPDATING file from an older FreeBSD release. 1742 1743Copyright information: 1744 1745Copyright 1998-2009 M.
