1 Updating Information for FreeBSD stable/12 users. 2 3This file is maintained and copyrighted by M. Warner Losh <imp@freebsd.org>. 4See end of file for further details. For commonly done items, please see the 5COMMON ITEMS: section later in the file. These instructions assume that you 6basically know what you are doing. If not, then please consult the FreeBSD 7handbook: 8 9 https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html 10 11Items affecting the ports and packages system can be found in 12/usr/ports/UPDATING. Please read that file before running portupgrade. 13 14NOTE: FreeBSD has switched from gcc to clang. If you have trouble bootstrapping 15from older versions of FreeBSD, try WITHOUT_CLANG and WITH_GCC to bootstrap to 16the tip of head, and then rebuild without this option. The bootstrap process 17from older version of current across the gcc/clang cutover is a bit fragile. 18 1920201027: 20 12.2-RELEASE. 21 2220200915: p1 FreeBSD-SA-20:27.ure 23 FreeBSD-SA-20:28.bhyve_vmcs 24 FreeBSD-SA-20:29.bhyve_svm 25 FreeBSD-SA-20:30.ftpd 26 27 Fix ure device driver susceptible to packet-in-packet attack. 28 [SA-20:27.ure] 29 30 Fix bhyve privilege escalation via VMCS access. [SA-20:28.bhyve_vmcs] 31 32 Fix bhyve SVM guest escape. [SA-20:29.bhyve_svm] 33 34 Fix ftpd privilege escalation via ftpchroot. [SA-20:30.ftpd] 35 3620200912: 37 The make.conf(5) MALLOC_PRODUCTION variable, used for disabling and 38 enabling assertions and statistics gathering in malloc(3), has been 39 migrated to a src.conf(5) WITH/WITHOUT_MALLOC_PRODUCTION option. 40 41 On stable branches, WITH_MALLOC_PRODUCTION is set by default, which 42 means that malloc(3) has assertions and statistics gathering disabled, 43 for improved performance. 44 45 For backwards compatibility, the make.conf(5) MALLOC_PRODUCTION is still 46 honored, but it is now deprecated and undocumented. 47 4820200909: 49 The resume code now notifies devd with the 'kernel' system 50 rather than the old 'kern' subsystem to be consistent with 51 other use. The old notification will be created as well, but 52 will be removed prior to FreeBSD 14.0. 53 5420200722: 55 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 56 been upgraded to 10.0.1. Please see the 20141231 entry below for 57 information about prerequisites and upgrading, if you are not already 58 using clang 3.5.0 or higher. 59 6020200708: 61 read(2) of a directory fd is now rejected by default. root may 62 re-enable it for the entire system with the 63 security.bsd.allow_read_dir sysctl(8) MIB. 64 65 It may be advised to setup aliases for grep to default to `-d skip` if 66 commonly non-recursively grepping a list that includes directories and 67 the potential for the resulting stderr output is not tolerable. Example 68 aliases are now installed, commented out, in /root/.cshrc. 69 7020200414: 71 Upstream DTS from Linux 5.6 was merged and they now have the SID 72 and THS (Secure ID controller and THermal Sensor) node present. 73 The DTB overlays have now been removed from the tree for the H3/H5 and 74 A64 SoCs and the aw_sid and aw_thermal driver have been updated to 75 deal with upstream DTS. If you are using those overlays you need to 76 remove them from loader.conf and update the DTBs on the FAT partition. 77 7820200501: 79 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 80 been upgraded to 10.0.0. Please see the 20141231 entry below for 81 information about prerequisites and upgrading, if you are not already 82 using clang 3.5.0 or higher. 83 8420200430: 85 The root certificates of the Mozilla CA Certificate Store have been 86 imported into the base system and can be managed with the certctl(8) 87 utility. If you have installed the security/ca_root_nss port or package 88 with the ETCSYMLINK option (the default), be advised that there may be 89 differences between those included in the port and those included in 90 base due to differences in nss branch used as well as general update 91 frequency. Note also that certctl(8) cannot manage certs in the 92 format used by the security/ca_root_nss port. 93 9420200107: 95 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 96 been upgraded to 9.0.1. Please see the 20141231 entry below for 97 information about prerequisites and upgrading, if you are not already 98 using clang 3.5.0 or higher. 99 10020191107: 101 The nctgpio and wbwd drivers have been moved to the superio bus. 102 If you have one of these drivers in a kernel configuration, then 103 you should add device superio to it. If you use one of these drivers 104 as a module and you compile a custom set of modules, then you should 105 add superio to the set. 106 10720191024: 108 The tap(4) driver has been folded into tun(4), and the module has been 109 renamed to tuntap. You should update any kld_list="if_tap" or 110 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 111 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 112 module instead, and "device tap" or "device tun" entries in kernel 113 config files to select the tuntap device instead. 114 11520190913: 116 ntpd no longer by default locks its pages in memory, allowing them 117 to be paged out by the kernel. Use rlimit memlock to restore 118 historic BSD behaviour. For example, add "rlimit memlock 32" 119 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 120 12120190914: 122 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 123 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 124 been removed from mount_fusefs(8). You can safely remove them from 125 your scripts, because they had no effect. 126 127 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 128 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 129 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 130 sysctls have been removed. If you felt the need to set any of them to 131 a non-default value, please tell asomers@FreeBSD.org why. 132 13320190906: 134 The fuse(4) module has been renamed to fusefs(4) for consistency with 135 other filesystems. You should update any kld_load="fuse" entries in 136 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 137 "options FUSE" enties in kernel config files. 138 13920190811: 140 Default permissions on the /var/account/acct file (and copies of it 141 rotated by periodic daily scripts) are changed from 0644 to 0640 142 because the file contains sensitive information that should not be 143 world-readable. If the /var/account directory must be created by 144 rc.d/accounting, the mode used is now 0750. Admins who use the 145 accounting feature are encouraged to change the mode of an existing 146 /var/account directory to 0750 or 0700. 147 14820190723: 149 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 150 been upgraded to 8.0.1. Please see the 20141231 entry below for 151 information about prerequisites and upgrading, if you are not already 152 using clang 3.5.0 or higher. 153 15420190413: 155 Now Clang 8 has been merged (see the 20190412 entry below), the ifunc 156 functionality needed for the RETPOLINE option should work properly 157 again. The RETPOLINE option has been removed from BROKEN_OPTIONS. 158 15920190412: 160 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 161 8.0.0. Please see the 20141231 entry below for information about 162 prerequisites and upgrading, if you are not already using clang 3.5.0 163 or higher. 164 16520190307: 166 The RETPOLINE option produces non-functional ifunc-using binaries 167 with Clang 7.0.1, and has been forced off (via BROKEN_OPTIONS). 168 Once Clang 8 is merged it may be enabled again. 169 17020190216: 171 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 172 7.0.1. Please see the 20141231 entry below for information about 173 prerequisites and upgrading, if you are not already using clang 3.5.0 174 or higher. 175 17620190226: 177 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 178 compiled into your custom kernel, add 'device xz' statement to the 179 kernel config. 180 18120190214: 182 Iflib is no longer unconditionally compiled into the kernel. Drivers 183 using iflib and statically compiled into the kernel, now require 184 the 'device iflib' config option. For the same drivers loaded as 185 modules on kernels not having 'device iflib', the iflib.ko module 186 is loaded automatically. 187 18820181228: 189 r342561 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 190 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 191 servers that have vfs.nfsd.nfs_privport set will only allow mounts 192 from clients using a reserved port#. Since both the FreeBSD and Linux 193 NFSv4 clients use reserved port#s by default, this should not affect 194 most NFSv4 mounts. 195 19620181129: 197 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 198 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 199 it produces broken binaries when ifuncs are in use. Users needing 200 GNU ld should install the binutils port or package. 201 20220181115: 203 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 204 has been converted to a port (misc/ctm) and will be removed from 205 FreeBSD-13. A depreciation warning will be printed to stderr by 206 the ctm command, but the functionality will remain in base for all 207 FreeBSD-12 releases. 208 20920181019: 210 The stable/12 branch has been created in subversion from head 211 revision r339432. 212 21320181015: 214 Ports for the DRM modules have been simplified. Now, amd64 users should 215 just install the drm-kmod port. All others should install 216 drm-legacy-kmod. 217 218 Graphics hardware that's newer than about 2010 usually works with 219 drm-kmod. For hardware older than 2013, however, some users will need 220 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 221 than 2008 usually only works in drm-legacy-kmod. The graphics team can 222 only commit to hardware made since 2013 due to the complexity of the 223 market and difficulty to test all the older cards effectively. If you 224 have hardware supported by drm-kmod, you are strongly encouraged to use 225 that as you will get better support. 226 227 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 228 elsewhere, the drm and drm2 modules will be eliminated from the src base 229 soon (with a limited exception for arm). Please update to the package asap 230 and report any issues to x11@freebsd.org. 231 232 Generally, anybody using the drm*-kmod packages should add 233 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 234 cross-threading surprises, especially with automatic driver 235 loading from X11 startup. These will become the defaults in 13-current 236 shortly. 237 23820181012: 239 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 240 custom kernel and module loading configuration files must be updated 241 accordingly. Moreover, interfaces previous presented as ixlvN to the 242 system are now exposed as iavfN and network configuration files must 243 be adjusted as necessary. 244 24520181009: 246 OpenSSL has been updated to version 1.1.1. This update included 247 additional various API changes througout the base system. It is 248 important to rebuild third-party software after upgrading. The value 249 of __FreeBSD_version has been bumped accordingly. 250 25120181006: 252 The legacy DRM modules and drivers have now been added to the loader's 253 module blacklist, in favor of loading them with kld_list in rc.conf(5). 254 The module blacklist may be overridden with the loader.conf(5) 255 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 256 encouraged. 257 25820181002: 259 The cam(4) based nda(4) driver will be used over nvd(4) by default on 260 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 261 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 262 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 263 nda device name. 264 26520180913: 266 Reproducible build mode is now on by default, in preparation for 267 FreeBSD 12.0. This eliminates build metadata such as the user, 268 host, and time from the kernel (and uname), unless the working tree 269 corresponds to a modified checkout from a version control system. 270 The previous behavior can be obtained by setting the /etc/src.conf 271 knob WITHOUT_REPRODUCIBLE_BUILD. 272 27320180826: 274 The Yarrow CSPRNG has been removed from the kernel as it has not been 275 supported by its designers since at least 2003. Fortuna has been the 276 default since FreeBSD-11. 277 27820180822: 279 devctl freeze/thaw have gone into the tree, the rc scripts have been 280 updated to use them and devmatch has been changed. You should update 281 kernel, userland and rc scripts all at the same time. 282 28320180818: 284 The default interpreter has been switched from 4th to Lua. 285 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 286 interpreter. If you have custom FORTH code you will need to set 287 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 288 src.conf for the build. This will create default hard links between 289 loader and loader_4th instead of loader and loader_lua, the new default. 290 If you are using UEFI it will create the proper hard link to loader.efi. 291 292 bhyve uses userboot.so. It remains 4th-only until some issues are solved 293 regarding coexisting with multiple versions of FreeBSD are resolved. 294 29520180815: 296 ls(1) now respects the COLORTERM environment variable used in other 297 systems and software to indicate that a colored terminal is both 298 supported and desired. If ls(1) is suddenly emitting colors, they may 299 be disabled again by either removing the unwanted COLORTERM from your 300 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 301 may not be observed in a future release. 302 30320180808: 304 The default pager for most commands has been changed to "less". To 305 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 306 your environment. 307 30820180731: 309 The jedec_ts(4) driver has been removed. A superset of its functionality 310 is available in the jedec_dimm(4) driver, and the manpage for that 311 driver includes migration instructions. If you have "device jedec_ts" 312 in your kernel configuration file, it must be removed. 313 31420180730: 315 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 316 This should have no effect if the kernel is booted via BIOS/legacy boot. 317 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 318 has a buggy firmware that prevents a successful boot due to use of 319 runtime services. 320 32120180727: 322 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 323 support has been removed from the tree. These ports were 324 obsolete and/or known to be broken for many years. 325 32620180723: 327 loader.efi has been augmented to participate more fully in the 328 UEFI boot manager protocol. loader.efi will now look at the 329 BootXXXX environment variable to determine if a specific kernel 330 or root partition was specified. XXXX is derived from BootCurrent. 331 efibootmgr(8) manages these standard UEFI variables. 332 33320180720: 334 zfsloader's functionality has now been folded into loader. 335 zfsloader is no longer necessary once you've updated your 336 boot blocks. For a transition period, we will install a 337 hardlink for zfsloader to loader to allow a smooth transition 338 until the boot blocks can be updated (hard link because old 339 zfs boot blocks don't understand symlinks). 340 34120180719: 342 ARM64 now have efifb support, if you want to have serial console 343 on your arm64 board when an screen is connected and the bootloader 344 setup a frambuffer for us to use, just add : 345 boot_serial=YES 346 boot_multicons=YES 347 in /boot/loader.conf 348 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 349 an screen connected as the firmware will setup a framebuffer are that 350 u-boot will expose as an EFI framebuffer. 351 35220180719: 353 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 354 or take steps to update /etc/passwd before doing installworld on 355 existing systems. Do not skip the "mergemaster -Fp" step before 356 installworld, as described in the update procedures near the bottom 357 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 358 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 359 the ntp config file contain options that change file/dir locations. 360 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 361 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 362 taking steps to ensure that all required files/dirs are accessible 363 by the ntpd user. 364 36520180717: 366 Big endian arm support has been removed. 367 36820180711: 369 The static environment setup in kernel configs is no longer mutually 370 exclusive with the loader(8) environment by default. In order to 371 restore the previous default behavior of disabling the loader(8) 372 environment if a static environment is present, you must specify 373 loader_env.disabled=1 in the static environment. 374 37520180705: 376 The ABI of syscalls used by management tools like sockstat and 377 netstat has been broken to allow 32-bit binaries to work on 378 64-bit kernels without modification. These programs will need 379 to match the kernel in order to function. External programs may 380 require minor modifications to accommodate a change of type in 381 structures from pointers to 64-bit virtual addresses. 382 38320180702: 384 On i386 and amd64 atomics are now inlined. Out of tree modules using 385 atomics will need to be rebuilt. 386 38720180701: 388 The '%I' format in the kern.corefile sysctl limits the number of 389 core files that a process can generate to the number stored in the 390 debug.ncores sysctl. The '%I' format is replaced by the single digit 391 index. Previously, if all indexes were taken the kernel would overwrite 392 only a core file with the highest index in a filename. 393 Currently the system will create a new core file if there is a free 394 index or if all slots are taken it will overwrite the oldest one. 395 39620180630: 397 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 398 6.0.1. Please see the 20141231 entry below for information about 399 prerequisites and upgrading, if you are not already using clang 3.5.0 400 or higher. 401 40220180628: 403 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 404 needed to be changed to work with it. This change was made with r335763 405 and requires a mergemaster / etcupdate / etc to update the installed file. 406 40720180612: 408 r334930 changed the interface between the NFS modules, so they all 409 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 410 41120180530: 412 As of r334391 lld is the default amd64 system linker; it is installed 413 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 414 longer necessary. 415 41620180530: 417 The kernel / userland interface for devinfo changed, so you'll 418 need a new kernel and userland as a pair for it to work (rebuilding 419 lib/libdevinfo is all that's required). devinfo and devmatch will 420 not work, but everything else will when there's a mismatch. 421 42220180523: 423 The on-disk format for hwpmc callchain records has changed to include 424 threadid corresponding to a given record. This changes the field offsets 425 and thus requires that libpmcstat be rebuilt before using a kernel 426 later than r334108. 427 42820180517: 429 The vxge(4) driver has been removed. This driver was introduced into 430 HEAD one week before the Exar left the Ethernet market and is not 431 known to be used. If you have device vxge in your kernel config file 432 it must be removed. 433 43420180510: 435 The amd64 kernel now requires a ld that supports ifunc to produce a 436 working kernel, either lld or a newer binutils. lld is built by default 437 on amd64, and the 'buildkernel' target uses it automatically. However, 438 it is not the default linker, so building the kernel the traditional 439 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 440 binutils port/package). lld will soon be default, and this requirement 441 will go away. 442 443 NOTE: As of r334391 lld is the default system linker on amd64, and no 444 workaround is necessary. 445 44620180508: 447 The nxge(4) driver has been removed. This driver was for PCI-X 10g 448 cards made by s2io/Neterion. The company was aquired by Exar and 449 no longer sells or supports Ethernet products. If you have device 450 nxge in your kernel config file it must be removed. 451 45220180504: 453 The tz database (tzdb) has been updated to 2018e. This version more 454 correctly models time stamps in time zones with negative DST such as 455 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 456 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 457 time zone abbreviations and the tm_isdst flag. 458 45920180502: 460 The ixgb(4) driver has been removed. This driver was for an early and 461 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 462 quickly shifted to the long lived ixgbe family. If you have device 463 ixgb in your kernel config file it must be removed. 464 46520180501: 466 The lmc(4) driver has been removed. This was a WAN interface 467 card that was already reportedly rare in 2003, and had an ambiguous 468 license. If you have device lmc in your kernel config file it must 469 be removed. 470 47120180413: 472 Support for Arcnet networks has been removed. If you have device 473 arcnet or device cm in your kernel config file they must be 474 removed. 475 47620180411: 477 Support for FDDI networks has been removed. If you have device 478 fddi or device fpa in your kernel config file they must be 479 removed. 480 48120180406: 482 In addition to supporting RFC 3164 formatted messages, the 483 syslogd(8) service is now capable of parsing RFC 5424 formatted 484 log messages. The main benefit of using RFC 5424 is that clients 485 may now send log messages with timestamps containing year numbers, 486 microseconds and time zone offsets. 487 488 Similarly, the syslog(3) C library function has been altered to 489 send RFC 5424 formatted messages to the local system logging 490 daemon. On systems using syslogd(8), this change should have no 491 negative impact, as long as syslogd(8) and the C library are 492 updated at the same time. On systems using a different system 493 logging daemon, it may be necessary to make configuration 494 adjustments, depending on the software used. 495 496 When using syslog-ng, add the 'syslog-protocol' flag to local 497 input sources to enable parsing of RFC 5424 formatted messages: 498 499 source src { 500 unix-dgram("/var/run/log" flags(syslog-protocol)); 501 } 502 503 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 504 of the 'imuxsock' module to let messages be processed by the 505 regular RFC 3164/5424 parsing pipeline: 506 507 module(load="imuxsock" SysSock.UseSpecialParser="off") 508 509 Do note that these changes only affect communication between local 510 applications and syslogd(8). The format that syslogd(8) uses to 511 store messages on disk or forward messages to other systems 512 remains unchanged. syslogd(8) still uses RFC 3164 for these 513 purposes. Options to customize this behaviour will be added in the 514 future. Utilities that process log files stored in /var/log are 515 thus expected to continue to function as before. 516 517 __FreeBSD_version has been incremented to 1200061 to denote this 518 change. 519 52020180328: 521 Support for token ring networks has been removed. If you 522 have "device token" in your kernel config you should remove 523 it. No device drivers supported token ring. 524 52520180323: 526 makefs was modified to be able to tag ISO9660 El Torito boot catalog 527 entries as EFI instead of overloading the i386 tag as done previously. 528 The amd64 mkisoimages.sh script used to build amd64 ISO images for 529 release was updated to use this. This may mean that makefs must be 530 updated before "make cdrom" can be run in the release directory. This 531 should be as simple as: 532 533 $ cd $SRCDIR/usr.sbin/makefs 534 $ make depend all install 535 53620180212: 537 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 538 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 539 Co-existance for the transition period will come shortly. Booting is a 540 complex environment and test coverage for Lua-enabled loaders has been 541 thin, so it would be prudent to assume it might not work and make 542 provisions for backup boot methods. 543 54420180211: 545 devmatch functionality has been turned on in devd. It will automatically 546 load drivers for unattached devices. This may cause unexpected drivers to 547 be loaded. Please report any problems to current@ and imp@freebsd.org. 548 54920180114: 550 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 551 6.0.0. Please see the 20141231 entry below for information about 552 prerequisites and upgrading, if you are not already using clang 3.5.0 553 or higher. 554 55520180110: 556 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 557 This means it is used to link the kernel and userland libraries and 558 executables, but is not yet installed as /usr/bin/ld by default. 559 560 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 561 WITHOUT_LLD_BOOTSTRAP=yes 562 56320180110: 564 On i386, pmtimer has been removed. Its functionality has been folded 565 into apm. It was a no-op on ACPI in current for a while now (but was still 566 needed on i386 in FreeBSD 11 and earlier). Users may need to remove it 567 from kernel config files. 568 56920180104: 570 The use of RSS hash from the network card aka flowid has been 571 disabled by default for lagg(4) as it's currently incompatible with 572 the lacp and loadbalance protocols. 573 574 This can be re-enabled by setting the following in loader.conf: 575 net.link.lagg.default_use_flowid="1" 576 57720180102: 578 The SW_WATCHDOG option is no longer necessary to enable the 579 hardclock-based software watchdog if no hardware watchdog is 580 configured. As before, SW_WATCHDOG will cause the software 581 watchdog to be enabled even if a hardware watchdog is configured. 582 58320171215: 584 r326887 fixes the issue described in the 20171214 UPDATING entry. 585 r326888 flips the switch back to building GELI support always. 586 58720171214: 588 r362593 broke ZFS + GELI support for reasons unknown. However, 589 it also broke ZFS support generally, so GELI has been turned off 590 by default as the lesser evil in r326857. If you boot off ZFS and/or 591 GELI, it might not be a good time to update. 592 59320171125: 594 PowerPC users must update loader(8) by rebuilding world before 595 installing a new kernel, as the protocol connecting them has 596 changed. Without the update, loader metadata will not be passed 597 successfully to the kernel and users will have to enter their 598 root partition at the kernel mountroot prompt to continue booting. 599 Newer versions of loader can boot old kernels without issue. 600 60120171110: 602 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 603 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 604 to WITH/OUT_LOADER_GELI. 605 60620171106: 607 The naive and non-compliant support of posix_fallocate(2) in ZFS 608 has been removed as of r325320. The system call now returns EINVAL 609 when used on a ZFS file. Although the new behavior complies with the 610 standard, some consumers are not prepared to cope with it. 611 One known victim is lld prior to r325420. 612 61320171102: 614 Building in a FreeBSD src checkout will automatically create object 615 directories now rather than store files in the current directory if 616 'make obj' was not ran. Calling 'make obj' is no longer necessary. 617 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 618 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 619 environment. 620 62120171101: 622 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 623 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 624 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 625 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 626 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 627 The UNIFIED_OBJDIR option is a transitional feature that will be 628 removed for 12.0 release; please migrate to the new format for any 629 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 630 than hardcoding paths. 631 63220171028: 633 The native-xtools target no longer installs the files by default to the 634 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 635 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 636 63720171021: 638 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 639 options are changing from controlling the build if defined / undefined 640 to controlling the build with explicit 'yes' or 'no' values. They will 641 shift to WITH/WITHOUT options to match other options in the system. 642 64320171010: 644 libstand has turned into a private library for sys/boot use only. 645 It is no longer supported as a public interface outside of sys/boot. 646 64720171005: 648 The arm port has split armv6 into armv6 and armv7. armv7 is now 649 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 650 and are running a kernel from before r324363, you will need to add 651 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 652 65320171003: 654 When building multiple kernels using KERNCONF, non-existent KERNCONF 655 files will produce an error and buildkernel will fail. Previously 656 missing KERNCONF files silently failed giving no indication as to 657 why, only to subsequently discover during installkernel that the 658 desired kernel was never built in the first place. 659 66020170912: 661 The default serial number format for CTL LUNs has changed. This will 662 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 663 or iSCSI clients care about their LUNs' serial numbers. Users who 664 require serial number stability should hardcode serial numbers in 665 /etc/ctl.conf . 666 66720170912: 668 For 32-bit arm compiled for hard-float support, soft-floating point 669 binaries now always get their shared libraries from 670 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 671 /usr/libsoft also existed). Only users with a hard-float ld.so, but 672 soft-float everything else should be affected. 673 67420170826: 675 The geli password typed at boot is now hidden. To restore the previous 676 behavior, see geli(8) for configuration options. 677 67820170825: 679 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 680 sysctl values. Minor nit, but requires a rebuild of both world/kernel 681 to complete. 682 68320170814: 684 "make check" behavior (made in ^/head@r295380) has been changed to 685 execute from a limited sandbox, as opposed to executing from 686 ${TESTSDIR}. 687 688 Behavioral changes: 689 - The "beforecheck" and "aftercheck" targets are now specified. 690 - ${CHECKDIR} (added in commit noted above) has been removed. 691 - Legacy behavior can be enabled by setting 692 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 693 694 If the limited sandbox mode is enabled, "make check" will execute 695 "make distribution", then install, execute the tests, and clean up the 696 sandbox if successful. 697 698 The "make distribution" and "make install" targets are typically run as 699 root to set appropriate permissions and ownership at installation time. 700 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 701 environment if executing "make check" with limited sandbox mode using 702 an unprivileged user. 703 70420170808: 705 Since the switch to GPT disk labels, fsck for UFS/FFS has been 706 unable to automatically find alternate superblocks. As of r322297, 707 the information needed to find alternate superblocks has been 708 moved to the end of the area reserved for the boot block. 709 Filesystems created with a newfs of this vintage or later 710 will create the recovery information. If you have a filesystem 711 created prior to this change and wish to have a recovery block 712 created for your filesystem, you can do so by running fsck in 713 foreground mode (i.e., do not use the -p or -y options). As it 714 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 715 to which you should answer yes. 716 71720170728: 718 As of r321665, an NFSv4 server configuration that services 719 Kerberos mounts or clients that do not support the uid/gid in 720 owner/owner_group string capability, must explicitly enable 721 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 722 machine's /etc/rc.conf file. 723 72420170722: 725 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 726 Please see the 20141231 entry below for information about prerequisites 727 and upgrading, if you are not already using clang 3.5.0 or higher. 728 72920170701: 730 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 731 r-commands (rlogin, rsh, etc.) to be built with the base system. 732 73320170625: 734 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 735 a very major ABI incompatible change, so users of FreeBSD/powerpc must 736 be careful when performing source upgrades. It is best to run 737 'make installworld' from an alternate root system, either a live 738 CD/memory stick, or a temporary root partition. Additionally, all ports 739 must be recompiled. powerpc64 is largely unaffected, except in the case 740 of 32-bit compatibility. All 32-bit binaries will be affected. 741 74220170623: 743 Forward compatibility for the "ino64" project have been committed. This 744 will allow most new binaries to run on older kernels in a limited 745 fashion. This prevents many of the common foot-shooting actions in the 746 upgrade as well as the limited ability to roll back the kernel across 747 the ino64 upgrade. Complicated use cases may not work properly, though 748 enough simpler ones work to allow recovery in most situations. 749 75020170620: 751 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 752 if you require the GPL compiler. 753 75420170618: 755 The internal ABI used for communication between the NFS kernel modules 756 was changed by r320085, so __FreeBSD_version was bumped to 757 ensure all the NFS related modules are updated together. 758 75920170617: 760 The ABI of struct event was changed by extending the data 761 member to 64bit and adding ext fields. For upgrade, same 762 precautions as for the entry 20170523 "ino64" must be 763 followed. 764 76520170531: 766 The GNU roff toolchain has been removed from base. To render manpages 767 which are not supported by mandoc(1), man(1) can fallback on GNU roff 768 from ports (and recommends to install it). 769 To render roff(7) documents, consider using GNU roff from ports or the 770 heirloom doctools roff toolchain from ports via pkg install groff or 771 via pkg install heirloom-doctools. 772 77320170524: 774 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 775 smaller runtime footprint builds. This is useful for embedded systems 776 which only require one chipset support. 777 778 If you load it as a module, make sure this is in /boot/loader.conf: 779 780 if_ath_load="YES" 781 782 This will load the HAL, all chip/RF backends and if_ath_pci. 783 If you have if_ath_pci in /boot/loader.conf, ensure it is after 784 if_ath or it will not load any HAL chipset support. 785 786 If you want to selectively load things (eg on ye cheape ARM/MIPS 787 platforms where RAM is at a premium) you should: 788 789 * load ath_hal 790 * load the chip modules in question 791 * load ath_rate, ath_dfs 792 * load ath_main 793 * load if_ath_pci and/or if_ath_ahb depending upon your particular 794 bus bind type - this is where probe/attach is done. 795 796 For further comments/feedback, poke adrian@ . 797 79820170523: 799 The "ino64" 64-bit inode project has been committed, which extends 800 a number of types to 64 bits. Upgrading in place requires care and 801 adherence to the documented upgrade procedure. 802 803 If using a custom kernel configuration ensure that the 804 COMPAT_FREEBSD11 option is included (as during the upgrade the 805 system will be running the ino64 kernel with the existing world). 806 807 For the safest in-place upgrade begin by removing previous build 808 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the 809 full procedure documented below under the heading "To rebuild 810 everything and install it on the current system." Specifically, 811 a reboot is required after installing the new kernel before 812 installing world. 813 81420170424: 815 The NATM framework including the en(4), fatm(4), hatm(4), and 816 patm(4) devices has been removed. Consumers should plan a 817 migration before the end-of-life date for FreeBSD 11. 818 81920170420: 820 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 821 diff has not been implemented, if those are needed a newer version of 822 GNU diff is available via the diffutils package under the gdiff name. 823 82420170413: 825 As of r316810 for ipfilter, keep frags is no longer assumed when 826 keep state is specified in a rule. r316810 aligns ipfilter with 827 documentation in man pages separating keep frags from keep state. 828 This allows keep state to be specified without forcing keep frags 829 and allows keep frags to be specified independently of keep state. 830 To maintain previous behaviour, also specify keep frags with 831 keep state (as documented in ipf.conf.5). 832 83320170407: 834 arm64 builds now use the base system LLD 4.0.0 linker by default, 835 instead of requiring that the aarch64-binutils port or package be 836 installed. To continue using aarch64-binutils, set 837 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 838 83920170405: 840 The UDP optimization in entry 20160818 that added the sysctl 841 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 842 packets will no longer be treated as L3 broadcast packets. 843 84420170331: 845 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 846 use any explicitly assigned loopback address available in the jail 847 instead of using the first assigned address of the jail. 848 84920170329: 850 The ctl.ko module no longer implements the iSCSI target frontend: 851 cfiscsi.ko does instead. 852 853 If building cfiscsi.ko as a kernel module, the module can be loaded 854 via one of the following methods: 855 - `cfiscsi_load="YES"` in loader.conf(5). 856 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 857 - ctladm(8)/ctld(8), when compiled with iSCSI support 858 (`WITH_ISCSI=yes` in src.conf(5)) 859 860 Please see cfiscsi(4) for more details. 861 86220170316: 863 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 864 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 865 same source (previously, the dependency of mmcsd.ko on mmc.ko was 866 missing, but mmcsd.ko now will refuse to load if it is incompatible 867 with mmc.ko). 868 86920170315: 870 The syntax of ipfw(8) named states was changed to avoid ambiguity. 871 If you have used named states in the firewall rules, you need to modify 872 them after installworld and before rebooting. Now named states must 873 be prefixed with colon. 874 87520170311: 876 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 877 removed as the userland we provide cannot use them. The KMS version 878 (sys/dev/drm2) supports the same hardware. 879 88020170302: 881 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 882 Please see the 20141231 entry below for information about prerequisites 883 and upgrading, if you are not already using clang 3.5.0 or higher. 884 88520170221: 886 The code that provides support for ZFS .zfs/ directory functionality 887 has been reimplemented. It's not possible now to create a snapshot 888 by mkdir under .zfs/snapshot/. That should be the only user visible 889 change. 890 89120170216: 892 EISA bus support has been removed. The WITH_EISA option is no longer 893 valid. 894 89520170215: 896 MCA bus support has been removed. 897 89820170127: 899 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 900 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 901 90220170112: 903 The EM_MULTIQUEUE kernel configuration option is deprecated now that 904 the em(4) driver conforms to iflib specifications. 905 90620170109: 907 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 908 IFLIB. If you have a custom kernel configuration that excludes em(4) 909 but you use igb(4), you need to re-add em(4) to your custom configuration. 910 91120161217: 912 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 913 Please see the 20141231 entry below for information about prerequisites 914 and upgrading, if you are not already using clang 3.5.0 or higher. 915 91620161124: 917 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 918 Please see the 20141231 entry below for information about prerequisites 919 and upgrading, if you are not already using clang 3.5.0 or higher. 920 92120161119: 922 The layout of the pmap structure has changed for powerpc to put the pmap 923 statistics at the front for all CPU variations. libkvm(3) and all tools 924 that link against it need to be recompiled. 925 92620161030: 927 isl(4) and cyapa(4) drivers now require a new driver, 928 chromebook_platform(4), to work properly on Chromebook-class hardware. 929 On other types of hardware the drivers may need to be configured using 930 device hints. Please see the corresponding manual pages for details. 931 93220161017: 933 The urtwn(4) driver was merged into rtwn(4) and now consists of 934 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 935 parts. 936 Also, firmware for RTL8188CE was renamed due to possible name 937 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 938 93920161015: 940 GNU rcs has been removed from base. It is available as packages: 941 - rcs: Latest GPLv3 GNU rcs version. 942 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 943 removed from base. 944 94520161008: 946 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 947 modules now requires that the kernel configuration contain the 948 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 949 95020161003: 951 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 952 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 953 95420160924: 955 Relocatable object files with the extension of .So have been renamed 956 to use an extension of .pico instead. The purpose of this change is 957 to avoid a name clash with shared libraries on case-insensitive file 958 systems. On those file systems, foo.So is the same file as foo.so. 959 96020160918: 961 GNU rcs has been turned off by default. It can (temporarily) be built 962 again by adding WITH_RCS knob in src.conf. 963 Otherwise, GNU rcs is available from packages: 964 - rcs: Latest GPLv3 GNU rcs version. 965 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 966 96720160918: 968 The backup_uses_rcs functionality has been removed from rc.subr. 969 97020160908: 971 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 972 two separate components, QUEUE_MACRO_DEBUG_TRACE and 973 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 974 QUEUE_MACRO_DEBUG behavior. 975 97620160824: 977 r304787 changed some ioctl interfaces between the iSCSI userspace 978 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 979 rebuilt to work with new kernels. __FreeBSD_version has been bumped 980 to 1200005. 981 98220160818: 983 The UDP receive code has been updated to only treat incoming UDP 984 packets that were addressed to an L2 broadcast address as L3 985 broadcast packets. It is not expected that this will affect any 986 standards-conforming UDP application. The new behaviour can be 987 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 988 0. 989 99020160818: 991 Remove the openbsd_poll system call. 992 __FreeBSD_version has been bumped because of this. 993 99420160708: 995 The stable/11 branch has been created from head@r302406. 996 99720160622: 998 The libc stub for the pipe(2) system call has been replaced with 999 a wrapper that calls the pipe2(2) system call and the pipe(2) 1000 system call is now only implemented by the kernels that include 1001 "options COMPAT_FREEBSD10" in their config file (this is the 1002 default). Users should ensure that this option is enabled in 1003 their kernel or upgrade userspace to r302092 before upgrading their 1004 kernel. 1005 100620160527: 1007 CAM will now strip leading spaces from SCSI disks' serial numbers. 1008 This will affect users who create UFS filesystems on SCSI disks using 1009 those disk's diskid device nodes. For example, if /etc/fstab 1010 previously contained a line like 1011 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 1012 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 1013 transforms like gmirror may also be affected. ZFS users should 1014 generally be fine. 1015 101620160523: 1017 The bitstring(3) API has been updated with new functionality and 1018 improved performance. But it is binary-incompatible with the old API. 1019 Objects built with the new headers may not be linked against objects 1020 built with the old headers. 1021 102220160520: 1023 The brk and sbrk functions have been removed from libc on arm64. 1024 Binutils from ports has been updated to not link to these 1025 functions and should be updated to the latest version before 1026 installing a new libc. 1027 102820160517: 1029 The armv6 port now defaults to hard float ABI. Limited support 1030 for running both hardfloat and soft float on the same system 1031 is available using the libraries installed with -DWITH_LIBSOFT. 1032 This has only been tested as an upgrade path for installworld 1033 and packages may fail or need manual intervention to run. New 1034 packages will be needed. 1035 1036 To update an existing self-hosted armv6hf system, you must add 1037 TARGET_ARCH=armv6 on the make command line for both the build 1038 and the install steps. 1039 104020160510: 1041 Kernel modules compiled outside of a kernel build now default to 1042 installing to /boot/modules instead of /boot/kernel. Many kernel 1043 modules built this way (such as those in ports) already overrode 1044 KMODDIR explicitly to install into /boot/modules. However, 1045 manually building and installing a module from /sys/modules will 1046 now install to /boot/modules instead of /boot/kernel. 1047 104820160414: 1049 The CAM I/O scheduler has been committed to the kernel. There should be 1050 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1051 list of known rogues that claim support for this but actually corrupt 1052 data is believed to be complete, be on the lookout for data 1053 corruption. The known rogue list is believed to be complete: 1054 1055 o Crucial MX100, M550 drives with MU01 firmware. 1056 o Micron M510 and M550 drives with MU01 firmware. 1057 o Micron M500 prior to MU07 firmware 1058 o Samsung 830, 840, and 850 all firmwares 1059 o FCCT M500 all firmwares 1060 1061 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1062 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1063 updated firmware. Black listed drives will work correctly because these 1064 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1065 this list is the same as found in Linux, it's believed there are no 1066 other rogues in the market place. All other models from the above 1067 vendors work. 1068 1069 To be safe, if you are at all concerned, you can quirk each of your 1070 drives to prevent NCQ from being sent by setting: 1071 kern.cam.ada.X.quirks="0x2" 1072 in loader.conf. If the drive requires the 4k sector quirk, set the 1073 quirks entry to 0x3. 1074 107520160330: 1076 The FAST_DEPEND build option has been removed and its functionality is 1077 now the one true way. The old mkdep(1) style of 'make depend' has 1078 been removed. See 20160311 for further details. 1079 108020160317: 1081 Resource range types have grown from unsigned long to uintmax_t. All 1082 drivers, and anything using libdevinfo, need to be recompiled. 1083 108420160311: 1085 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1086 builds. It no longer runs mkdep(1) during 'make depend', and the 1087 'make depend' stage can safely be skipped now as it is auto ran 1088 when building 'make all' and will generate all SRCS and DPSRCS before 1089 building anything else. Dependencies are gathered at compile time with 1090 -MF flags kept in separate .depend files per object file. Users should 1091 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1092 stale .depend files. 1093 109420160306: 1095 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1096 kernel modules. Therefore, if you load any kernel modules at boot time, 1097 please install the boot loaders after you install the kernel, but before 1098 rebooting, e.g.: 1099 1100 make buildworld 1101 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1102 make installkernel KERNCONF=YOUR_KERNEL_HERE 1103 make -C sys/boot install 1104 <reboot in single user> 1105 1106 Then follow the usual steps, described in the General Notes section, 1107 below. 1108 110920160305: 1110 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1111 see the 20141231 entry below for information about prerequisites and 1112 upgrading, if you are not already using clang 3.5.0 or higher. 1113 111420160301: 1115 The AIO subsystem is now a standard part of the kernel. The 1116 VFS_AIO kernel option and aio.ko kernel module have been removed. 1117 Due to stability concerns, asynchronous I/O requests are only 1118 permitted on sockets and raw disks by default. To enable 1119 asynchronous I/O requests on all file types, set the 1120 vfs.aio.enable_unsafe sysctl to a non-zero value. 1121 112220160226: 1123 The ELF object manipulation tool objcopy is now provided by the 1124 ELF Tool Chain project rather than by GNU binutils. It should be a 1125 drop-in replacement, with the addition of arm64 support. The 1126 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1127 to obtain the GNU version if necessary. 1128 112920160129: 1130 Building ZFS pools on top of zvols is prohibited by default. That 1131 feature has never worked safely; it's always been prone to deadlocks. 1132 Using a zvol as the backing store for a VM guest's virtual disk will 1133 still work, even if the guest is using ZFS. Legacy behavior can be 1134 restored by setting vfs.zfs.vol.recursive=1. 1135 113620160119: 1137 The NONE and HPN patches has been removed from OpenSSH. They are 1138 still available in the security/openssh-portable port. 1139 114020160113: 1141 With the addition of ypldap(8), a new _ypldap user is now required 1142 during installworld. "mergemaster -p" can be used to add the user 1143 prior to installworld, as documented in the handbook. 1144 114520151216: 1146 The tftp loader (pxeboot) now uses the option root-path directive. As a 1147 consequence it no longer looks for a pxeboot.4th file on the tftp 1148 server. Instead it uses the regular /boot infrastructure as with the 1149 other loaders. 1150 115120151211: 1152 The code to start recording plug and play data into the modules has 1153 been committed. While the old tools will properly build a new kernel, 1154 a number of warnings about "unknown metadata record 4" will be produced 1155 for an older kldxref. To avoid such warnings, make sure to rebuild 1156 the kernel toolchain (or world). Make sure that you have r292078 or 1157 later when trying to build 292077 or later before rebuilding. 1158 115920151207: 1160 Debug data files are now built by default with 'make buildworld' and 1161 installed with 'make installworld'. This facilitates debugging but 1162 requires more disk space both during the build and for the installed 1163 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1164 in src.conf(5). 1165 116620151130: 1167 r291527 changed the internal interface between the nfsd.ko and 1168 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1169 __FreeBSD_version has been bumped because of this. 1170 117120151108: 1172 Add support for unicode collation strings leads to a change of 1173 order of files listed by ls(1) for example. To get back to the old 1174 behaviour, set LC_COLLATE environment variable to "C". 1175 1176 Databases administrators will need to reindex their databases given 1177 collation results will be different. 1178 1179 Due to a bug in install(1) it is recommended to remove the ancient 1180 locales before running make installworld. 1181 1182 rm -rf /usr/share/locale/* 1183 118420151030: 1185 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1186 libcrypto.so.7 or libssl.so.7 must be recompiled. 1187 118820151020: 1189 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1190 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1191 should be replaced with isp_2400 and isp_2500 modules respectively. 1192 119320151017: 1194 The build previously allowed using 'make -n' to not recurse into 1195 sub-directories while showing what commands would be executed, and 1196 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1197 and 'make -N' will not. 1198 119920151012: 1200 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1201 and etcupdate will now use this file. A custom sendmail.cf is now 1202 updated via this mechanism rather than via installworld. If you had 1203 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1204 want to remove the exclusion or change it to "always install". 1205 /etc/mail/sendmail.cf is now managed the same way regardless of 1206 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1207 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1208 120920151011: 1210 Compatibility shims for legacy ATA device names have been removed. 1211 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1212 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1213 environment variables, /dev/ad* and /dev/ar* symbolic links. 1214 121520151006: 1216 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1217 Please see the 20141231 entry below for information about prerequisites 1218 and upgrading, if you are not already using clang 3.5.0 or higher. 1219 122020150924: 1221 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1222 and renamed from .symbols to .debug. This reduces the size requirements 1223 on the boot partition or file system and provides consistency with 1224 userland debug files. 1225 1226 When using the supported kernel installation method the 1227 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1228 as is done with /boot/kernel. 1229 1230 Developers wishing to maintain the historical behavior of installing 1231 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1232 123320150827: 1234 The wireless drivers had undergone changes that remove the 'parent 1235 interface' from the ifconfig -l output. The rc.d network scripts 1236 used to check presence of a parent interface in the list, so old 1237 scripts would fail to start wireless networking. Thus, etcupdate(3) 1238 or mergemaster(8) run is required after kernel update, to update your 1239 rc.d scripts in /etc. 1240 124120150827: 1242 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1243 These configurations are now automatically interpreted as 1244 'scrub fragment reassemble'. 1245 124620150817: 1247 Kernel-loadable modules for the random(4) device are back. To use 1248 them, the kernel must have 1249 1250 device random 1251 options RANDOM_LOADABLE 1252 1253 kldload(8) can then be used to load random_fortuna.ko 1254 or random_yarrow.ko. Please note that due to the indirect 1255 function calls that the loadable modules need to provide, 1256 the build-in variants will be slightly more efficient. 1257 1258 The random(4) kernel option RANDOM_DUMMY has been retired due to 1259 unpopularity. It was not all that useful anyway. 1260 126120150813: 1262 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1263 Control over building the ELF Tool Chain tools is now provided by 1264 the WITHOUT_TOOLCHAIN knob. 1265 126620150810: 1267 The polarity of Pulse Per Second (PPS) capture events with the 1268 uart(4) driver has been corrected. Prior to this change the PPS 1269 "assert" event corresponded to the trailing edge of a positive PPS 1270 pulse and the "clear" event was the leading edge of the next pulse. 1271 1272 As the width of a PPS pulse in a typical GPS receiver is on the 1273 order of 1 millisecond, most users will not notice any significant 1274 difference with this change. 1275 1276 Anyone who has compensated for the historical polarity reversal by 1277 configuring a negative offset equal to the pulse width will need to 1278 remove that workaround. 1279 128020150809: 1281 The default group assigned to /dev/dri entries has been changed 1282 from 'wheel' to 'video' with the id of '44'. If you want to have 1283 access to the dri devices please add yourself to the video group 1284 with: 1285 1286 # pw groupmod video -m $USER 1287 128820150806: 1289 The menu.rc and loader.rc files will now be replaced during 1290 upgrades. Please migrate local changes to menu.rc.local and 1291 loader.rc.local instead. 1292 129320150805: 1294 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1295 strings and strip have been removed. The src.conf(5) knob 1296 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1297 129820150728: 1299 As ZFS requires more kernel stack pages than is the default on some 1300 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1301 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1302 1303 Please consider using 'options KSTACK_PAGES=X' where X is greater 1304 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1305 130620150706: 1307 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1308 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1309 default, i.e., they will not contain "::". For example, instead 1310 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1311 to have a more specific match, such as different map entries for 1312 IPv6:0:0 vs IPv6:0. This change requires that configuration 1313 data (including maps, files, classes, custom ruleset, etc.) must 1314 use the same format, so make certain such configuration data is 1315 upgrading. As a very simple check search for patterns like 1316 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1317 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1318 the cf option UseCompressedIPv6Addresses. 1319 132020150630: 1321 The default kernel entropy-processing algorithm is now 1322 Fortuna, replacing Yarrow. 1323 1324 Assuming you have 'device random' in your kernel config 1325 file, the configurations allow a kernel option to override 1326 this default. You may choose *ONE* of: 1327 1328 options RANDOM_YARROW # Legacy /dev/random algorithm. 1329 options RANDOM_DUMMY # Blocking-only driver. 1330 1331 If you have neither, you get Fortuna. For most people, 1332 read no further, Fortuna will give a /dev/random that works 1333 like it always used to, and the difference will be irrelevant. 1334 1335 If you remove 'device random', you get *NO* kernel-processed 1336 entropy at all. This may be acceptable to folks building 1337 embedded systems, but has complications. Carry on reading, 1338 and it is assumed you know what you need. 1339 1340 *PLEASE* read random(4) and random(9) if you are in the 1341 habit of tweaking kernel configs, and/or if you are a member 1342 of the embedded community, wanting specific and not-usual 1343 behaviour from your security subsystems. 1344 1345 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1346 random', you will NOT have a functioning /dev/random, and 1347 many cryptographic features will not work, including SSH. 1348 You may also find strange behaviour from the random(3) set 1349 of library functions, in particular sranddev(3), srandomdev(3) 1350 and arc4random(3). The reason for this is that the KERN_ARND 1351 sysctl only returns entropy if it thinks it has some to 1352 share, and with RANDOM_DUMMY or no 'device random' this 1353 will never happen. 1354 135520150623: 1356 An additional fix for the issue described in the 20150614 sendmail 1357 entry below has been committed in revision 284717. 1358 135920150616: 1360 FreeBSD's old make (fmake) has been removed from the system. It is 1361 available as the devel/fmake port or via pkg install fmake. 1362 136320150615: 1364 The fix for the issue described in the 20150614 sendmail entry 1365 below has been committed in revision 284436. The work 1366 around described in that entry is no longer needed unless the 1367 default setting is overridden by a confDH_PARAMETERS configuration 1368 setting of '5' or pointing to a 512 bit DH parameter file. 1369 137020150614: 1371 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1372 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1373 and devel/kyua to version 0.20+ and adjust any calling code to work 1374 with Kyuafile and kyua. 1375 137620150614: 1377 The import of openssl to address the FreeBSD-SA-15:10.openssl 1378 security advisory includes a change which rejects handshakes 1379 with DH parameters below 768 bits. sendmail releases prior 1380 to 8.15.2 (not yet released), defaulted to a 512 bit 1381 DH parameter setting for client connections. To work around 1382 this interoperability, sendmail can be configured to use a 1383 2048 bit DH parameter by: 1384 1385 1. Edit /etc/mail/`hostname`.mc 1386 2. If a setting for confDH_PARAMETERS does not exist or 1387 exists and is set to a string beginning with '5', 1388 replace it with '2'. 1389 3. If a setting for confDH_PARAMETERS exists and is set to 1390 a file path, create a new file with: 1391 openssl dhparam -out /path/to/file 2048 1392 4. Rebuild the .cf file: 1393 cd /etc/mail/; make; make install 1394 5. Restart sendmail: 1395 cd /etc/mail/; make restart 1396 1397 A sendmail patch is coming, at which time this file will be 1398 updated. 1399 140020150604: 1401 Generation of legacy formatted entries have been disabled by default 1402 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1403 entries were converted to use the new format by default when the new, 1404 machine independent format have been added and supported since FreeBSD 1405 5.x. 1406 1407 Please see the pwd_mkdb(8) manual page for further details. 1408 140920150525: 1410 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1411 20141231 entry below for information about prerequisites and upgrading, 1412 if you are not already using 3.5.0 or higher. 1413 141420150521: 1415 TI platform code switched to using vendor DTS files and this update 1416 may break existing systems running on Beaglebone, Beaglebone Black, 1417 and Pandaboard: 1418 1419 - dtb files should be regenerated/reinstalled. Filenames are the 1420 same but content is different now 1421 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1422 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1423 addressing scheme is now pin 25 on /dev/gpioc3. 1424 - Pandaboard: /etc/ttys should be updated, serial console device is 1425 now /dev/ttyu2, not /dev/ttyu0 1426 142720150501: 1428 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1429 If you need the GNU extension from groff soelim(1), install groff 1430 from package: pkg install groff, or via ports: textproc/groff. 1431 143220150423: 1433 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1434 defined in symlink(7); previously symlinks were silently ignored. 1435 143620150415: 1437 The const qualifier has been removed from iconv(3) to comply with 1438 POSIX. The ports tree is aware of this from r384038 onwards. 1439 144020150416: 1441 Libraries specified by LIBADD in Makefiles must have a corresponding 1442 DPADD_<lib> variable to ensure correct dependencies. This is now 1443 enforced in src.libnames.mk. 1444 144520150324: 1446 From legacy ata(4) driver was removed support for SATA controllers 1447 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1448 Kernel modules ataahci and ataadaptec were removed completely, 1449 replaced by ahci and mvs modules respectively. 1450 145120150315: 1452 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1453 the 20141231 entry below for information about prerequisites and 1454 upgrading, if you are not already using 3.5.0 or higher. 1455 145620150307: 1457 The 32-bit PowerPC kernel has been changed to a position-independent 1458 executable. This can only be booted with a version of loader(8) 1459 newer than January 31, 2015, so make sure to update both world and 1460 kernel before rebooting. 1461 146220150217: 1463 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1464 but before r278950, the RNG was not seeded properly. Immediately 1465 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1466 ssh keys or openssl keys) that were generated w/ a kernel from that 1467 range. This does not affect programs that directly used /dev/random 1468 or /dev/urandom. All userland uses of arc4random(3) are affected. 1469 147020150210: 1471 The autofs(4) ABI was changed in order to restore binary compatibility 1472 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1473 with the new kernel. 1474 147520150131: 1476 The powerpc64 kernel has been changed to a position-independent 1477 executable. This can only be booted with a new version of loader(8), 1478 so make sure to update both world and kernel before rebooting. 1479 148020150118: 1481 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1482 only release, no new features have been added. Please see the 20141231 1483 entry below for information about prerequisites and upgrading, if you 1484 are not already using 3.5.0. 1485 148620150107: 1487 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1488 taken from the ELF Tool Chain project rather than GNU binutils. They 1489 should be drop-in replacements, with the addition of arm64 support. 1490 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1491 binutils tools, if necessary. See 20150805 for updated information. 1492 149320150105: 1494 The default Unbound configuration now enables remote control 1495 using a local socket. Users who have already enabled the 1496 local_unbound service should regenerate their configuration 1497 by running "service local_unbound setup" as root. 1498 149920150102: 1500 The GNU texinfo and GNU info pages have been removed. 1501 To be able to view GNU info pages please install texinfo from ports. 1502 150320141231: 1504 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1505 1506 As of this release, a prerequisite for building clang, llvm and lldb is 1507 a C++11 capable compiler and C++11 standard library. This means that to 1508 be able to successfully build the cross-tools stage of buildworld, with 1509 clang as the bootstrap compiler, your system compiler or cross compiler 1510 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1511 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1512 later. 1513 1514 On any standard FreeBSD 10.x or 11.x installation, where clang and 1515 libc++ are on by default (that is, on x86 or arm), this should work out 1516 of the box. 1517 1518 On 9.x installations where clang is enabled by default, e.g. on x86 and 1519 powerpc, libc++ will not be enabled by default, so libc++ should be 1520 built (with clang) and installed first. If both clang and libc++ are 1521 missing, build clang first, then use it to build libc++. 1522 1523 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1524 the instructions for 9.x above. 1525 1526 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1527 default, and do not build clang. 1528 1529 Many embedded systems are resource constrained, and will not be able to 1530 build clang in a reasonable time, or in some cases at all. In those 1531 cases, cross building bootable systems on amd64 is a workaround. 1532 1533 This new version of clang introduces a number of new warnings, of which 1534 the following are most likely to appear: 1535 1536 -Wabsolute-value 1537 1538 This warns in two cases, for both C and C++: 1539 * When the code is trying to take the absolute value of an unsigned 1540 quantity, which is effectively a no-op, and almost never what was 1541 intended. The code should be fixed, if at all possible. If you are 1542 sure that the unsigned quantity can be safely cast to signed, without 1543 loss of information or undefined behavior, you can add an explicit 1544 cast, or disable the warning. 1545 1546 * When the code is trying to take an absolute value, but the called 1547 abs() variant is for the wrong type, which can lead to truncation. 1548 If you want to disable the warning instead of fixing the code, please 1549 make sure that truncation will not occur, or it might lead to unwanted 1550 side-effects. 1551 1552 -Wtautological-undefined-compare and 1553 -Wundefined-bool-conversion 1554 1555 These warn when C++ code is trying to compare 'this' against NULL, while 1556 'this' should never be NULL in well-defined C++ code. However, there is 1557 some legacy (pre C++11) code out there, which actively abuses this 1558 feature, which was less strictly defined in previous C++ versions. 1559 1560 Squid and openjdk do this, for example. The warning can be turned off 1561 for C++98 and earlier, but compiling the code in C++11 mode might result 1562 in unexpected behavior; for example, the parts of the program that are 1563 unreachable could be optimized away. 1564 156520141222: 1566 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1567 kernel sources have been removed. The .h files remain, since some 1568 utilities include them. This will need to be fixed later. 1569 If "mount -t oldnfs ..." is attempted, it will fail. 1570 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1571 the utilities will report errors. 1572 157320141121: 1574 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1575 directories to top level SUBDIR variable when their parent 1576 directory is included in LOCAL_DIRS. Users with build systems with 1577 such hierarchies and without SUBDIR entries in the parent 1578 directory Makefiles should add them or add the directories to 1579 LOCAL_DIRS. 1580 158120141109: 1582 faith(4) and faithd(8) have been removed from the base system. Faith 1583 has been obsolete for a very long time. 1584 158520141104: 1586 vt(4), the new console driver, is enabled by default. It brings 1587 support for Unicode and double-width characters, as well as 1588 support for UEFI and integration with the KMS kernel video 1589 drivers. 1590 1591 You may need to update your console settings in /etc/rc.conf, 1592 most probably the keymap. During boot, /etc/rc.d/syscons will 1593 indicate what you need to do. 1594 1595 vt(4) still has issues and lacks some features compared to 1596 syscons(4). See the wiki for up-to-date information: 1597 https://wiki.freebsd.org/Newcons 1598 1599 If you want to keep using syscons(4), you can do so by adding 1600 the following line to /boot/loader.conf: 1601 kern.vty=sc 1602 160320141102: 1604 pjdfstest has been integrated into kyua as an opt-in test suite. 1605 Please see share/doc/pjdfstest/README for more details on how to 1606 execute it. 1607 160820141009: 1609 gperf has been removed from the base system for architectures 1610 that use clang. Ports that require gperf will obtain it from the 1611 devel/gperf port. 1612 161320140923: 1614 pjdfstest has been moved from tools/regression/pjdfstest to 1615 contrib/pjdfstest . 1616 161720140922: 1618 At svn r271982, The default linux compat kernel ABI has been adjusted 1619 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1620 update. If you wish to continue using the linux-f10 compat ports, 1621 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1622 encouraged to update their linux-compat packages to linux-c6 during 1623 their next update cycle. 1624 162520140729: 1626 The ofwfb driver, used to provide a graphics console on PowerPC when 1627 using vt(4), no longer allows mmap() of all physical memory. This 1628 will prevent Xorg on PowerPC with some ATI graphics cards from 1629 initializing properly unless x11-servers/xorg-server is updated to 1630 1.12.4_8 or newer. 1631 163220140723: 1633 The xdev targets have been converted to using TARGET and 1634 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1635 163620140719: 1637 The default unbound configuration has been modified to address 1638 issues with reverse lookups on networks that use private 1639 address ranges. If you use the local_unbound service, run 1640 "service local_unbound setup" as root to regenerate your 1641 configuration, then "service local_unbound reload" to load the 1642 new configuration. 1643 164420140709: 1645 The GNU texinfo and GNU info pages are not built and installed 1646 anymore, WITH_INFO knob has been added to allow to built and install 1647 them again. 1648 UPDATE: see 20150102 entry on texinfo's removal 1649 165020140708: 1651 The GNU readline library is now an INTERNALLIB - that is, it is 1652 statically linked into consumers (GDB and variants) in the base 1653 system, and the shared library is no longer installed. The 1654 devel/readline port is available for third party software that 1655 requires readline. 1656 165720140702: 1658 The Itanium architecture (ia64) has been removed from the list of 1659 known architectures. This is the first step in the removal of the 1660 architecture. 1661 166220140701: 1663 Commit r268115 has added NFSv4.1 server support, merged from 1664 projects/nfsv4.1-server. Since this includes changes to the 1665 internal interfaces between the NFS related modules, a full 1666 build of the kernel and modules will be necessary. 1667 __FreeBSD_version has been bumped. 1668 166920140629: 1670 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1671 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1672 which differs from the behaviour controlled by this knob.) 1673 167420140619: 1675 Maximal length of the serial number in CTL was increased from 16 to 1676 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1677 and ctld, need to be rebuilt to work with a new kernel. 1678 167920140606: 1680 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1681 1 respectively to match the upstream numbers. They were out of 1682 sync because, when they were originally added to FreeBSD, the 1683 upstream versions were not respected. These libraries are private 1684 and not yet built by default, so renumbering them should be a 1685 non-issue. However, unclean source trees will yield broken test 1686 programs once the operator executes "make delete-old-libs" after a 1687 "make installworld". 1688 1689 Additionally, the atf-sh binary was made private by moving it into 1690 /usr/libexec/. Already-built shell test programs will keep the 1691 path to the old binary so they will break after "make delete-old" 1692 is run. 1693 1694 If you are using WITH_TESTS=yes (not the default), wipe the object 1695 tree and rebuild from scratch to prevent spurious test failures. 1696 This is only needed once: the misnumbered libraries and misplaced 1697 binaries have been added to OptionalObsoleteFiles.inc so they will 1698 be removed during a clean upgrade. 1699 170020140512: 1701 Clang and llvm have been upgraded to 3.4.1 release. 1702 170320140508: 1704 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1705 be removed to avoid issues in the future (and has been added to 1706 ObsoleteFiles.inc). 1707 170820140505: 1709 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1710 past, it affected all builds that used the bsd.*.mk files. The old 1711 behavior was a bug, but people may have relied upon it. To get this 1712 behavior back, you can .include /etc/src.conf from /etc/make.conf 1713 (which is still global and isn't changed). This also changes the 1714 behavior of incremental builds inside the tree of individual 1715 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1716 Although this has survived make universe and some upgrade scenarios, 1717 other upgrade scenarios may have broken. At least one form of 1718 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1719 as well... In cases where MAKESYSPATH isn't working with this 1720 setting, you'll need to set it to the full path to your tree. 1721 1722 One side effect of all this cleaning up is that bsd.compiler.mk 1723 is no longer implicitly included by bsd.own.mk. If you wish to 1724 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1725 as well. 1726 172720140430: 1728 The lindev device has been removed since /dev/full has been made a 1729 standard device. __FreeBSD_version has been bumped. 1730 173120140424: 1732 The knob WITHOUT_VI was added to the base system, which controls 1733 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1734 in order to reorder files share/termcap and didn't build ex(1) as a 1735 build tool, so building/installing with WITH_VI is highly advised for 1736 build hosts for older releases. 1737 1738 This issue has been fixed in stable/9 and stable/10 in r277022 and 1739 r276991, respectively. 1740 174120140418: 1742 The YES_HESIOD knob has been removed. It has been obsolete for 1743 a decade. Please move to using WITH_HESIOD instead or your builds 1744 will silently lack HESIOD. 1745 174620140405: 1747 The uart(4) driver has been changed with respect to its handling 1748 of the low-level console. Previously the uart(4) driver prevented 1749 any process from changing the baudrate or the CLOCAL and HUPCL 1750 control flags. By removing the restrictions, operators can make 1751 changes to the serial console port without having to reboot. 1752 However, when getty(8) is started on the serial device that is 1753 associated with the low-level console, a misconfigured terminal 1754 line in /etc/ttys will now have a real impact. 1755 Before upgrading the kernel, make sure that /etc/ttys has the 1756 serial console device configured as 3wire without baudrate to 1757 preserve the previous behaviour. E.g: 1758 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1759 176020140306: 1761 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1762 to improve performance. To re-enable it, if needed, run rpcbind 1763 with command line option -W. 1764 176520140226: 1766 Switched back to the GPL dtc compiler due to updates in the upstream 1767 dts files not being supported by the BSDL dtc compiler. You will need 1768 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1769 may result while building dtb files during a kernel build if you fail 1770 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1771 177220140216: 1773 Clang and llvm have been upgraded to 3.4 release. 1774 177520140216: 1776 The nve(4) driver has been removed. Please use the nfe(4) driver 1777 for NVIDIA nForce MCP Ethernet adapters instead. 1778 177920140212: 1780 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1781 This could cause certain C++ applications using shared libraries built 1782 against the previous version of libc++ to crash. The incompatibility 1783 has now been fixed, but any C++ applications or shared libraries built 1784 between r261283 and r261801 should be recompiled. 1785 178620140204: 1787 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1788 capability mode support. Please note that enabling the feature in 1789 kernel is still highly recommended. 1790 179120140131: 1792 OpenSSH is now built with sandbox support, and will use sandbox as 1793 the default privilege separation method. This requires Capsicum 1794 capability mode support in kernel. 1795 179620140128: 1797 The libelf and libdwarf libraries have been updated to newer 1798 versions from upstream. Shared library version numbers for 1799 these two libraries were bumped. Any ports or binaries 1800 requiring these two libraries should be recompiled. 1801 __FreeBSD_version is bumped to 1100006. 1802 180320140110: 1804 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1805 instead of providing an explicit one, this would prevent such 1806 Makefile from providing its own Kyuafile in the future during 1807 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1808 intervention is needed to clean an objdir if you use NO_CLEAN: 1809 # find /usr/obj -name Kyuafile | xargs rm -f 1810 181120131213: 1812 The behavior of gss_pseudo_random() for the krb5 mechanism 1813 has changed, for applications requesting a longer random string 1814 than produced by the underlying enctype's pseudo-random() function. 1815 In particular, the random string produced from a session key of 1816 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1817 be different at the 17th octet and later, after this change. 1818 The counter used in the PRF+ construction is now encoded as a 1819 big-endian integer in accordance with RFC 4402. 1820 __FreeBSD_version is bumped to 1100004. 1821 182220131108: 1823 The WITHOUT_ATF build knob has been removed and its functionality 1824 has been subsumed into the more generic WITHOUT_TESTS. If you were 1825 using the former to disable the build of the ATF libraries, you 1826 should change your settings to use the latter. 1827 182820131025: 1829 The default version of mtree is nmtree which is obtained from 1830 NetBSD. The output is generally the same, but may vary 1831 slightly. If you found you need identical output adding 1832 "-F freebsd9" to the command line should do the trick. For the 1833 time being, the old mtree is available as fmtree. 1834 183520131014: 1836 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1837 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1838 1.1.4_8 and verify bsdyml not linked in, before running "make 1839 delete-old-libs": 1840 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1841 or 1842 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1843 184420131010: 1845 The stable/10 branch has been created in subversion from head 1846 revision r256279. 1847 1848COMMON ITEMS: 1849 1850 General Notes 1851 ------------- 1852 Avoid using make -j when upgrading. While generally safe, there are 1853 sometimes problems using -j to upgrade. If your upgrade fails with 1854 -j, please try again without -j. From time to time in the past there 1855 have been problems using -j with buildworld and/or installworld. This 1856 is especially true when upgrading between "distant" versions (eg one 1857 that cross a major release boundary or several minor releases, or when 1858 several months have passed on the -current branch). 1859 1860 Sometimes, obscure build problems are the result of environment 1861 poisoning. This can happen because the make utility reads its 1862 environment when searching for values for global variables. To run 1863 your build attempts in an "environmental clean room", prefix all make 1864 commands with 'env -i '. See the env(1) manual page for more details. 1865 1866 When upgrading from one major version to another it is generally best to 1867 upgrade to the latest code in the currently installed branch first, then 1868 do an upgrade to the new branch. This is the best-tested upgrade path, 1869 and has the highest probability of being successful. Please try this 1870 approach if you encounter problems with a major version upgrade. Since 1871 the stable 4.x branch point, one has generally been able to upgrade from 1872 anywhere in the most recent stable branch to head / current (or even the 1873 last couple of stable branches). See the top of this file when there's 1874 an exception. 1875 1876 When upgrading a live system, having a root shell around before 1877 installing anything can help undo problems. Not having a root shell 1878 around can lead to problems if pam has changed too much from your 1879 starting point to allow continued authentication after the upgrade. 1880 1881 This file should be read as a log of events. When a later event changes 1882 information of a prior event, the prior event should not be deleted. 1883 Instead, a pointer to the entry with the new information should be 1884 placed in the old entry. Readers of this file should also sanity check 1885 older entries before relying on them blindly. Authors of new entries 1886 should write them with this in mind. 1887 1888 ZFS notes 1889 --------- 1890 When upgrading the boot ZFS pool to a new version, always follow 1891 these two steps: 1892 1893 1.) recompile and reinstall the ZFS boot loader and boot block 1894 (this is part of "make buildworld" and "make installworld") 1895 1896 2.) update the ZFS boot block on your boot drive 1897 1898 The following example updates the ZFS boot block on the first 1899 partition (freebsd-boot) of a GPT partitioned drive ada0: 1900 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1901 1902 Non-boot pools do not need these updates. 1903 1904 To build a kernel 1905 ----------------- 1906 If you are updating from a prior version of FreeBSD (even one just 1907 a few days old), you should follow this procedure. It is the most 1908 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1909 1910 make kernel-toolchain 1911 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1912 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1913 1914 To test a kernel once 1915 --------------------- 1916 If you just want to boot a kernel once (because you are not sure 1917 if it works, or if you want to boot a known bad kernel to provide 1918 debugging information) run 1919 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1920 nextboot -k testkernel 1921 1922 To rebuild everything and install it on the current system. 1923 ----------------------------------------------------------- 1924 # Note: sometimes if you are running current you gotta do more than 1925 # is listed here if you are upgrading from a really old current. 1926 1927 <make sure you have good level 0 dumps> 1928 make buildworld 1929 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1930 make installkernel KERNCONF=YOUR_KERNEL_HERE 1931 [1] 1932 <reboot in single user> [3] 1933 mergemaster -Fp [5] 1934 make installworld 1935 mergemaster -Fi [4] 1936 make delete-old [6] 1937 <reboot> 1938 1939 To cross-install current onto a separate partition 1940 -------------------------------------------------- 1941 # In this approach we use a separate partition to hold 1942 # current's root, 'usr', and 'var' directories. A partition 1943 # holding "/", "/usr" and "/var" should be about 2GB in 1944 # size. 1945 1946 <make sure you have good level 0 dumps> 1947 <boot into -stable> 1948 make buildworld 1949 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1950 <maybe newfs current's root partition> 1951 <mount current's root partition on directory ${CURRENT_ROOT}> 1952 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1953 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1954 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1955 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1956 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1957 <reboot into current> 1958 <do a "native" rebuild/install as described in the previous section> 1959 <maybe install compatibility libraries from ports/misc/compat*> 1960 <reboot> 1961 1962 1963 To upgrade in-place from stable to current 1964 ---------------------------------------------- 1965 <make sure you have good level 0 dumps> 1966 make buildworld [9] 1967 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1968 make installkernel KERNCONF=YOUR_KERNEL_HERE 1969 [1] 1970 <reboot in single user> [3] 1971 mergemaster -Fp [5] 1972 make installworld 1973 mergemaster -Fi [4] 1974 make delete-old [6] 1975 <reboot> 1976 1977 Make sure that you've read the UPDATING file to understand the 1978 tweaks to various things you need. At this point in the life 1979 cycle of current, things change often and you are on your own 1980 to cope. The defaults can also change, so please read ALL of 1981 the UPDATING entries. 1982 1983 Also, if you are tracking -current, you must be subscribed to 1984 freebsd-current@freebsd.org. Make sure that before you update 1985 your sources that you have read and understood all the recent 1986 messages there. If in doubt, please track -stable which has 1987 much fewer pitfalls. 1988 1989 [1] If you have third party modules, such as vmware, you 1990 should disable them at this point so they don't crash your 1991 system on reboot. 1992 1993 [3] From the bootblocks, boot -s, and then do 1994 fsck -p 1995 mount -u / 1996 mount -a 1997 cd src 1998 adjkerntz -i # if CMOS is wall time 1999 Also, when doing a major release upgrade, it is required that 2000 you boot into single user mode to do the installworld. 2001 2002 [4] Note: This step is non-optional. Failure to do this step 2003 can result in a significant reduction in the functionality of the 2004 system. Attempting to do it by hand is not recommended and those 2005 that pursue this avenue should read this file carefully, as well 2006 as the archives of freebsd-current and freebsd-hackers mailing lists 2007 for potential gotchas. The -U option is also useful to consider. 2008 See mergemaster(8) for more information. 2009 2010 [5] Usually this step is a no-op. However, from time to time 2011 you may need to do this if you get unknown user in the following 2012 step. It never hurts to do it all the time. You may need to 2013 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2014 install) after the buildworld before this step if you last updated 2015 from current before 20130425 or from -stable before 20130430. 2016 2017 [6] This only deletes old files and directories. Old libraries 2018 can be deleted by "make delete-old-libs", but you have to make 2019 sure that no program is using those libraries anymore. 2020 2021 [8] The new kernel must be able to run existing binaries used by 2022 an installworld. When upgrading across major versions, the new 2023 kernel's configuration must include the correct COMPAT_FREEBSD<n> 2024 option for existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x 2025 binaries). Failure to do so may leave you with a system that is 2026 hard to boot to recover. A GENERIC kernel will include suitable 2027 compatibility options to run binaries from older branches. 2028 2029 Make sure that you merge any new devices from GENERIC since the 2030 last time you updated your kernel config file. 2031 2032 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2033 "?=" instead of the "=" assignment operator, so that buildworld can 2034 override the CPUTYPE if it needs to. 2035 2036 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2037 not on the command line, or in /etc/make.conf. buildworld will 2038 warn if it is improperly defined. 2039FORMAT: 2040 2041This file contains a list, in reverse chronological order, of major 2042breakages in tracking -current. It is not guaranteed to be a complete 2043list of such breakages, and only contains entries since September 23, 2011. 2044If you need to see UPDATING entries from before that date, you will need 2045to fetch an UPDATING file from an older FreeBSD release. 2046 2047Copyright information: 2048 2049Copyright 1998-2009 M.
