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 updating system packages 13and/or ports. 14 15NOTE: FreeBSD has switched from gcc to clang. If you have trouble bootstrapping 16from older versions of FreeBSD, try WITHOUT_CLANG and WITH_GCC to bootstrap to 17the tip of head, and then rebuild without this option. The bootstrap process 18from older version of current across the gcc/clang cutover is a bit fragile. 19 2020220222: 21 Kernel-loadable random(4) modules are supported again, but are no 22 longer unloadable. 23 2420220214: 25 The following knobs have been added related to tradeoffs between 26 safe use of the random device and availability in the absence of 27 entropy: 28 29 kern.random.initial_seeding.bypass_before_seeding: tunable; set 30 non-zero to bypass the random device prior to seeding, or zero to 31 block random requests until the random device is initially seeded. 32 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 33 availability properties. 34 35 kern.random.initial_seeding.read_random_bypassed_before_seeding: 36 read-only diagnostic sysctl that is set when bypass is enabled and 37 read_random(9) is bypassed, to enable programmatic handling of this 38 initial condition, if desired. 39 40 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 41 Similar to the above, but for arc4random(9) initial seeding. 42 43 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 44 non-zero to disable warnings in dmesg when the same conditions are 45 met as for the diagnostic sysctls above. Defaults to zero, i.e., 46 produce warnings in dmesg when the conditions are met. 47 48 The loadable random module KPI has changed; the random_infra_init() 49 routine now requires a 3rd function pointer for a bool (*)(void) 50 method that returns true if the random device is seeded (and 51 therefore unblocked). 52 5320211214: 54 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 55 been upgraded to 11.0.0. Please see the 20141231 entry below for 56 information about prerequisites and upgrading, if you are not already 57 using clang 3.5.0 or higher. 58 5920210730: 60 Commit b69019c14cd8 removes pf's DIOCGETSTATESNV ioctl. 61 As of be70c7a50d32 it is no longer used by userspace, but it does mean 62 users may not be able to enumerate pf states if they update the kernel 63 past c021ff986e2b without first updating userspace past be70c7a50d32. 64 6520210715: 66 The 20210707 awk update brought in a change in behavior. This has 67 been corrected as of d4d252c49976. Between these dates, if you 68 installed a new awk binary, you may not be able to build a new 69 kernel because the change in behavior affected the genoffset 70 script used to build the kernel. If you did update, the fix is 71 to update your sources past the above hash and do 72 % cd usr.bin/awk 73 % make clean all 74 % sudo -E make install 75 to enable building kernels again. 76 7720210710: 78 awk has been updated to the latest one-true-awk version 20210215. 79 This contains a number of minor bug fixes. 80 8120210626: 82 Commit 6ae32cc8182f changed the internal KAPI between the krpc and 83 nfsd modules. As such, both need to be rebuilt from sources. 84 Bump __FreeBSD_version to 1202508. 85 8620210510: 87 Commit e9959506d2cc changed the internal KAPI between the 88 nscl.ko and nfscommon.ko modules, so they both need to be 89 rebuilt from sources. 90 9120210430: 92 Commit 0a1fdb867c72 changed the internal KAPI between 93 the krpc and NFS. As such, the krpc, nfscommon and 94 nfscl modules must all be rebuilt from sources. 95 Without this patch, NFSv4.1 mounts should not 96 be done with the nfscbd(8) daemon running, to avoid 97 needing a working back channel for server->client RPCs. 98 9920200912: 100 The make.conf(5) MALLOC_PRODUCTION variable, used for disabling and 101 enabling assertions and statistics gathering in malloc(3), has been 102 migrated to a src.conf(5) WITH/WITHOUT_MALLOC_PRODUCTION option. 103 104 On stable branches, WITH_MALLOC_PRODUCTION is set by default, which 105 means that malloc(3) has assertions and statistics gathering disabled, 106 for improved performance. 107 108 For backwards compatibility, the make.conf(5) MALLOC_PRODUCTION is still 109 honored, but it is now deprecated and undocumented. 110 11120200909: 112 The resume code now notifies devd with the 'kernel' system 113 rather than the old 'kern' subsystem to be consistent with 114 other use. The old notification will be created as well, but 115 will be removed prior to FreeBSD 14.0. 116 11720200722: 118 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 119 been upgraded to 10.0.1. Please see the 20141231 entry below for 120 information about prerequisites and upgrading, if you are not already 121 using clang 3.5.0 or higher. 122 12320200708: 124 read(2) of a directory fd is now rejected by default. root may 125 re-enable it for the entire system with the 126 security.bsd.allow_read_dir sysctl(8) MIB. 127 128 It may be advised to setup aliases for grep to default to `-d skip` if 129 commonly non-recursively grepping a list that includes directories and 130 the potential for the resulting stderr output is not tolerable. Example 131 aliases are now installed, commented out, in /root/.cshrc. 132 13320200414: 134 Upstream DTS from Linux 5.6 was merged and they now have the SID 135 and THS (Secure ID controller and THermal Sensor) node present. 136 The DTB overlays have now been removed from the tree for the H3/H5 and 137 A64 SoCs and the aw_sid and aw_thermal driver have been updated to 138 deal with upstream DTS. If you are using those overlays you need to 139 remove them from loader.conf and update the DTBs on the FAT partition. 140 14120200501: 142 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 143 been upgraded to 10.0.0. Please see the 20141231 entry below for 144 information about prerequisites and upgrading, if you are not already 145 using clang 3.5.0 or higher. 146 14720200430: 148 The root certificates of the Mozilla CA Certificate Store have been 149 imported into the base system and can be managed with the certctl(8) 150 utility. If you have installed the security/ca_root_nss port or package 151 with the ETCSYMLINK option (the default), be advised that there may be 152 differences between those included in the port and those included in 153 base due to differences in nss branch used as well as general update 154 frequency. Note also that certctl(8) cannot manage certs in the 155 format used by the security/ca_root_nss port. 156 15720200107: 158 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 159 been upgraded to 9.0.1. Please see the 20141231 entry below for 160 information about prerequisites and upgrading, if you are not already 161 using clang 3.5.0 or higher. 162 16320191107: 164 The nctgpio and wbwd drivers have been moved to the superio bus. 165 If you have one of these drivers in a kernel configuration, then 166 you should add device superio to it. If you use one of these drivers 167 as a module and you compile a custom set of modules, then you should 168 add superio to the set. 169 17020191024: 171 The tap(4) driver has been folded into tun(4), and the module has been 172 renamed to tuntap. You should update any kld_list="if_tap" or 173 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 174 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 175 module instead, and "device tap" or "device tun" entries in kernel 176 config files to select the tuntap device instead. 177 17820190913: 179 ntpd no longer by default locks its pages in memory, allowing them 180 to be paged out by the kernel. Use rlimit memlock to restore 181 historic BSD behaviour. For example, add "rlimit memlock 32" 182 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 183 18420190914: 185 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 186 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 187 been removed from mount_fusefs(8). You can safely remove them from 188 your scripts, because they had no effect. 189 190 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 191 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 192 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 193 sysctls have been removed. If you felt the need to set any of them to 194 a non-default value, please tell asomers@FreeBSD.org why. 195 19620190906: 197 The fuse(4) module has been renamed to fusefs(4) for consistency with 198 other filesystems. You should update any kld_load="fuse" entries in 199 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 200 "options FUSE" enties in kernel config files. 201 20220190811: 203 Default permissions on the /var/account/acct file (and copies of it 204 rotated by periodic daily scripts) are changed from 0644 to 0640 205 because the file contains sensitive information that should not be 206 world-readable. If the /var/account directory must be created by 207 rc.d/accounting, the mode used is now 0750. Admins who use the 208 accounting feature are encouraged to change the mode of an existing 209 /var/account directory to 0750 or 0700. 210 21120190723: 212 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 213 been upgraded to 8.0.1. Please see the 20141231 entry below for 214 information about prerequisites and upgrading, if you are not already 215 using clang 3.5.0 or higher. 216 21720190413: 218 Now Clang 8 has been merged (see the 20190412 entry below), the ifunc 219 functionality needed for the RETPOLINE option should work properly 220 again. The RETPOLINE option has been removed from BROKEN_OPTIONS. 221 22220190412: 223 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 224 8.0.0. Please see the 20141231 entry below for information about 225 prerequisites and upgrading, if you are not already using clang 3.5.0 226 or higher. 227 22820190307: 229 The RETPOLINE option produces non-functional ifunc-using binaries 230 with Clang 7.0.1, and has been forced off (via BROKEN_OPTIONS). 231 Once Clang 8 is merged it may be enabled again. 232 23320190216: 234 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 235 7.0.1. Please see the 20141231 entry below for information about 236 prerequisites and upgrading, if you are not already using clang 3.5.0 237 or higher. 238 23920190226: 240 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 241 compiled into your custom kernel, add 'device xz' statement to the 242 kernel config. 243 24420190214: 245 Iflib is no longer unconditionally compiled into the kernel. Drivers 246 using iflib and statically compiled into the kernel, now require 247 the 'device iflib' config option. For the same drivers loaded as 248 modules on kernels not having 'device iflib', the iflib.ko module 249 is loaded automatically. 250 25120181228: 252 r342561 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 253 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 254 servers that have vfs.nfsd.nfs_privport set will only allow mounts 255 from clients using a reserved port#. Since both the FreeBSD and Linux 256 NFSv4 clients use reserved port#s by default, this should not affect 257 most NFSv4 mounts. 258 25920181129: 260 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 261 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 262 it produces broken binaries when ifuncs are in use. Users needing 263 GNU ld should install the binutils port or package. 264 26520181115: 266 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 267 has been converted to a port (misc/ctm) and will be removed from 268 FreeBSD-13. A depreciation warning will be printed to stderr by 269 the ctm command, but the functionality will remain in base for all 270 FreeBSD-12 releases. 271 27220181019: 273 The stable/12 branch has been created in subversion from head 274 revision r339432. 275 27620181015: 277 Ports for the DRM modules have been simplified. Now, amd64 users should 278 just install the drm-kmod port. All others should install 279 drm-legacy-kmod. 280 281 Graphics hardware that's newer than about 2010 usually works with 282 drm-kmod. For hardware older than 2013, however, some users will need 283 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 284 than 2008 usually only works in drm-legacy-kmod. The graphics team can 285 only commit to hardware made since 2013 due to the complexity of the 286 market and difficulty to test all the older cards effectively. If you 287 have hardware supported by drm-kmod, you are strongly encouraged to use 288 that as you will get better support. 289 290 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 291 elsewhere, the drm and drm2 modules will be eliminated from the src base 292 soon (with a limited exception for arm). Please update to the package asap 293 and report any issues to x11@freebsd.org. 294 295 Generally, anybody using the drm*-kmod packages should add 296 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 297 cross-threading surprises, especially with automatic driver 298 loading from X11 startup. These will become the defaults in 13-current 299 shortly. 300 30120181012: 302 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 303 custom kernel and module loading configuration files must be updated 304 accordingly. Moreover, interfaces previous presented as ixlvN to the 305 system are now exposed as iavfN and network configuration files must 306 be adjusted as necessary. 307 30820181009: 309 OpenSSL has been updated to version 1.1.1. This update included 310 additional various API changes througout the base system. It is 311 important to rebuild third-party software after upgrading. The value 312 of __FreeBSD_version has been bumped accordingly. 313 31420181006: 315 The legacy DRM modules and drivers have now been added to the loader's 316 module blacklist, in favor of loading them with kld_list in rc.conf(5). 317 The module blacklist may be overridden with the loader.conf(5) 318 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 319 encouraged. 320 32120181002: 322 The cam(4) based nda(4) driver will be used over nvd(4) by default on 323 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 324 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 325 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 326 nda device name. 327 32820180913: 329 Reproducible build mode is now on by default, in preparation for 330 FreeBSD 12.0. This eliminates build metadata such as the user, 331 host, and time from the kernel (and uname), unless the working tree 332 corresponds to a modified checkout from a version control system. 333 The previous behavior can be obtained by setting the /etc/src.conf 334 knob WITHOUT_REPRODUCIBLE_BUILD. 335 33620180826: 337 The Yarrow CSPRNG has been removed from the kernel as it has not been 338 supported by its designers since at least 2003. Fortuna has been the 339 default since FreeBSD-11. 340 34120180822: 342 devctl freeze/thaw have gone into the tree, the rc scripts have been 343 updated to use them and devmatch has been changed. You should update 344 kernel, userland and rc scripts all at the same time. 345 34620180818: 347 The default interpreter has been switched from 4th to Lua. 348 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 349 interpreter. If you have custom FORTH code you will need to set 350 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 351 src.conf for the build. This will create default hard links between 352 loader and loader_4th instead of loader and loader_lua, the new default. 353 If you are using UEFI it will create the proper hard link to loader.efi. 354 355 bhyve uses userboot.so. It remains 4th-only until some issues are solved 356 regarding coexisting with multiple versions of FreeBSD are resolved. 357 35820180815: 359 ls(1) now respects the COLORTERM environment variable used in other 360 systems and software to indicate that a colored terminal is both 361 supported and desired. If ls(1) is suddenly emitting colors, they may 362 be disabled again by either removing the unwanted COLORTERM from your 363 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 364 may not be observed in a future release. 365 36620180808: 367 The default pager for most commands has been changed to "less". To 368 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 369 your environment. 370 37120180731: 372 The jedec_ts(4) driver has been removed. A superset of its functionality 373 is available in the jedec_dimm(4) driver, and the manpage for that 374 driver includes migration instructions. If you have "device jedec_ts" 375 in your kernel configuration file, it must be removed. 376 37720180730: 378 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 379 This should have no effect if the kernel is booted via BIOS/legacy boot. 380 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 381 has a buggy firmware that prevents a successful boot due to use of 382 runtime services. 383 38420180727: 385 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 386 support has been removed from the tree. These ports were 387 obsolete and/or known to be broken for many years. 388 38920180723: 390 loader.efi has been augmented to participate more fully in the 391 UEFI boot manager protocol. loader.efi will now look at the 392 BootXXXX environment variable to determine if a specific kernel 393 or root partition was specified. XXXX is derived from BootCurrent. 394 efibootmgr(8) manages these standard UEFI variables. 395 39620180720: 397 zfsloader's functionality has now been folded into loader. 398 zfsloader is no longer necessary once you've updated your 399 boot blocks. For a transition period, we will install a 400 hardlink for zfsloader to loader to allow a smooth transition 401 until the boot blocks can be updated (hard link because old 402 zfs boot blocks don't understand symlinks). 403 40420180719: 405 ARM64 now have efifb support, if you want to have serial console 406 on your arm64 board when an screen is connected and the bootloader 407 setup a frambuffer for us to use, just add : 408 boot_serial=YES 409 boot_multicons=YES 410 in /boot/loader.conf 411 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 412 an screen connected as the firmware will setup a framebuffer are that 413 u-boot will expose as an EFI framebuffer. 414 41520180719: 416 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 417 or take steps to update /etc/passwd before doing installworld on 418 existing systems. Do not skip the "mergemaster -Fp" step before 419 installworld, as described in the update procedures near the bottom 420 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 421 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 422 the ntp config file contain options that change file/dir locations. 423 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 424 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 425 taking steps to ensure that all required files/dirs are accessible 426 by the ntpd user. 427 42820180717: 429 Big endian arm support has been removed. 430 43120180711: 432 The static environment setup in kernel configs is no longer mutually 433 exclusive with the loader(8) environment by default. In order to 434 restore the previous default behavior of disabling the loader(8) 435 environment if a static environment is present, you must specify 436 loader_env.disabled=1 in the static environment. 437 43820180705: 439 The ABI of syscalls used by management tools like sockstat and 440 netstat has been broken to allow 32-bit binaries to work on 441 64-bit kernels without modification. These programs will need 442 to match the kernel in order to function. External programs may 443 require minor modifications to accommodate a change of type in 444 structures from pointers to 64-bit virtual addresses. 445 44620180702: 447 On i386 and amd64 atomics are now inlined. Out of tree modules using 448 atomics will need to be rebuilt. 449 45020180701: 451 The '%I' format in the kern.corefile sysctl limits the number of 452 core files that a process can generate to the number stored in the 453 debug.ncores sysctl. The '%I' format is replaced by the single digit 454 index. Previously, if all indexes were taken the kernel would overwrite 455 only a core file with the highest index in a filename. 456 Currently the system will create a new core file if there is a free 457 index or if all slots are taken it will overwrite the oldest one. 458 45920180630: 460 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 461 6.0.1. Please see the 20141231 entry below for information about 462 prerequisites and upgrading, if you are not already using clang 3.5.0 463 or higher. 464 46520180628: 466 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 467 needed to be changed to work with it. This change was made with r335763 468 and requires a mergemaster / etcupdate / etc to update the installed file. 469 47020180612: 471 r334930 changed the interface between the NFS modules, so they all 472 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 473 47420180530: 475 As of r334391 lld is the default amd64 system linker; it is installed 476 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 477 longer necessary. 478 47920180530: 480 The kernel / userland interface for devinfo changed, so you'll 481 need a new kernel and userland as a pair for it to work (rebuilding 482 lib/libdevinfo is all that's required). devinfo and devmatch will 483 not work, but everything else will when there's a mismatch. 484 48520180523: 486 The on-disk format for hwpmc callchain records has changed to include 487 threadid corresponding to a given record. This changes the field offsets 488 and thus requires that libpmcstat be rebuilt before using a kernel 489 later than r334108. 490 49120180517: 492 The vxge(4) driver has been removed. This driver was introduced into 493 HEAD one week before the Exar left the Ethernet market and is not 494 known to be used. If you have device vxge in your kernel config file 495 it must be removed. 496 49720180510: 498 The amd64 kernel now requires a ld that supports ifunc to produce a 499 working kernel, either lld or a newer binutils. lld is built by default 500 on amd64, and the 'buildkernel' target uses it automatically. However, 501 it is not the default linker, so building the kernel the traditional 502 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 503 binutils port/package). lld will soon be default, and this requirement 504 will go away. 505 506 NOTE: As of r334391 lld is the default system linker on amd64, and no 507 workaround is necessary. 508 50920180508: 510 The nxge(4) driver has been removed. This driver was for PCI-X 10g 511 cards made by s2io/Neterion. The company was aquired by Exar and 512 no longer sells or supports Ethernet products. If you have device 513 nxge in your kernel config file it must be removed. 514 51520180504: 516 The tz database (tzdb) has been updated to 2018e. This version more 517 correctly models time stamps in time zones with negative DST such as 518 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 519 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 520 time zone abbreviations and the tm_isdst flag. 521 52220180502: 523 The ixgb(4) driver has been removed. This driver was for an early and 524 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 525 quickly shifted to the long lived ixgbe family. If you have device 526 ixgb in your kernel config file it must be removed. 527 52820180501: 529 The lmc(4) driver has been removed. This was a WAN interface 530 card that was already reportedly rare in 2003, and had an ambiguous 531 license. If you have device lmc in your kernel config file it must 532 be removed. 533 53420180413: 535 Support for Arcnet networks has been removed. If you have device 536 arcnet or device cm in your kernel config file they must be 537 removed. 538 53920180411: 540 Support for FDDI networks has been removed. If you have device 541 fddi or device fpa in your kernel config file they must be 542 removed. 543 54420180406: 545 In addition to supporting RFC 3164 formatted messages, the 546 syslogd(8) service is now capable of parsing RFC 5424 formatted 547 log messages. The main benefit of using RFC 5424 is that clients 548 may now send log messages with timestamps containing year numbers, 549 microseconds and time zone offsets. 550 551 Similarly, the syslog(3) C library function has been altered to 552 send RFC 5424 formatted messages to the local system logging 553 daemon. On systems using syslogd(8), this change should have no 554 negative impact, as long as syslogd(8) and the C library are 555 updated at the same time. On systems using a different system 556 logging daemon, it may be necessary to make configuration 557 adjustments, depending on the software used. 558 559 When using syslog-ng, add the 'syslog-protocol' flag to local 560 input sources to enable parsing of RFC 5424 formatted messages: 561 562 source src { 563 unix-dgram("/var/run/log" flags(syslog-protocol)); 564 } 565 566 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 567 of the 'imuxsock' module to let messages be processed by the 568 regular RFC 3164/5424 parsing pipeline: 569 570 module(load="imuxsock" SysSock.UseSpecialParser="off") 571 572 Do note that these changes only affect communication between local 573 applications and syslogd(8). The format that syslogd(8) uses to 574 store messages on disk or forward messages to other systems 575 remains unchanged. syslogd(8) still uses RFC 3164 for these 576 purposes. Options to customize this behaviour will be added in the 577 future. Utilities that process log files stored in /var/log are 578 thus expected to continue to function as before. 579 580 __FreeBSD_version has been incremented to 1200061 to denote this 581 change. 582 58320180328: 584 Support for token ring networks has been removed. If you 585 have "device token" in your kernel config you should remove 586 it. No device drivers supported token ring. 587 58820180323: 589 makefs was modified to be able to tag ISO9660 El Torito boot catalog 590 entries as EFI instead of overloading the i386 tag as done previously. 591 The amd64 mkisoimages.sh script used to build amd64 ISO images for 592 release was updated to use this. This may mean that makefs must be 593 updated before "make cdrom" can be run in the release directory. This 594 should be as simple as: 595 596 $ cd $SRCDIR/usr.sbin/makefs 597 $ make depend all install 598 59920180212: 600 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 601 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 602 Co-existance for the transition period will come shortly. Booting is a 603 complex environment and test coverage for Lua-enabled loaders has been 604 thin, so it would be prudent to assume it might not work and make 605 provisions for backup boot methods. 606 60720180211: 608 devmatch functionality has been turned on in devd. It will automatically 609 load drivers for unattached devices. This may cause unexpected drivers to 610 be loaded. Please report any problems to current@ and imp@freebsd.org. 611 61220180114: 613 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 614 6.0.0. Please see the 20141231 entry below for information about 615 prerequisites and upgrading, if you are not already using clang 3.5.0 616 or higher. 617 61820180110: 619 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 620 This means it is used to link the kernel and userland libraries and 621 executables, but is not yet installed as /usr/bin/ld by default. 622 623 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 624 WITHOUT_LLD_BOOTSTRAP=yes 625 62620180110: 627 On i386, pmtimer has been removed. Its functionality has been folded 628 into apm. It was a no-op on ACPI in current for a while now (but was still 629 needed on i386 in FreeBSD 11 and earlier). Users may need to remove it 630 from kernel config files. 631 63220180104: 633 The use of RSS hash from the network card aka flowid has been 634 disabled by default for lagg(4) as it's currently incompatible with 635 the lacp and loadbalance protocols. 636 637 This can be re-enabled by setting the following in loader.conf: 638 net.link.lagg.default_use_flowid="1" 639 64020180102: 641 The SW_WATCHDOG option is no longer necessary to enable the 642 hardclock-based software watchdog if no hardware watchdog is 643 configured. As before, SW_WATCHDOG will cause the software 644 watchdog to be enabled even if a hardware watchdog is configured. 645 64620171215: 647 r326887 fixes the issue described in the 20171214 UPDATING entry. 648 r326888 flips the switch back to building GELI support always. 649 65020171214: 651 r362593 broke ZFS + GELI support for reasons unknown. However, 652 it also broke ZFS support generally, so GELI has been turned off 653 by default as the lesser evil in r326857. If you boot off ZFS and/or 654 GELI, it might not be a good time to update. 655 65620171125: 657 PowerPC users must update loader(8) by rebuilding world before 658 installing a new kernel, as the protocol connecting them has 659 changed. Without the update, loader metadata will not be passed 660 successfully to the kernel and users will have to enter their 661 root partition at the kernel mountroot prompt to continue booting. 662 Newer versions of loader can boot old kernels without issue. 663 66420171110: 665 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 666 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 667 to WITH/OUT_LOADER_GELI. 668 66920171106: 670 The naive and non-compliant support of posix_fallocate(2) in ZFS 671 has been removed as of r325320. The system call now returns EINVAL 672 when used on a ZFS file. Although the new behavior complies with the 673 standard, some consumers are not prepared to cope with it. 674 One known victim is lld prior to r325420. 675 67620171102: 677 Building in a FreeBSD src checkout will automatically create object 678 directories now rather than store files in the current directory if 679 'make obj' was not ran. Calling 'make obj' is no longer necessary. 680 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 681 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 682 environment. 683 68420171101: 685 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 686 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 687 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 688 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 689 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 690 The UNIFIED_OBJDIR option is a transitional feature that will be 691 removed for 12.0 release; please migrate to the new format for any 692 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 693 than hardcoding paths. 694 69520171028: 696 The native-xtools target no longer installs the files by default to the 697 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 698 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 699 70020171021: 701 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 702 options are changing from controlling the build if defined / undefined 703 to controlling the build with explicit 'yes' or 'no' values. They will 704 shift to WITH/WITHOUT options to match other options in the system. 705 70620171010: 707 libstand has turned into a private library for sys/boot use only. 708 It is no longer supported as a public interface outside of sys/boot. 709 71020171005: 711 The arm port has split armv6 into armv6 and armv7. armv7 is now 712 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 713 and are running a kernel from before r324363, you will need to add 714 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 715 71620171003: 717 When building multiple kernels using KERNCONF, non-existent KERNCONF 718 files will produce an error and buildkernel will fail. Previously 719 missing KERNCONF files silently failed giving no indication as to 720 why, only to subsequently discover during installkernel that the 721 desired kernel was never built in the first place. 722 72320170912: 724 The default serial number format for CTL LUNs has changed. This will 725 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 726 or iSCSI clients care about their LUNs' serial numbers. Users who 727 require serial number stability should hardcode serial numbers in 728 /etc/ctl.conf . 729 73020170912: 731 For 32-bit arm compiled for hard-float support, soft-floating point 732 binaries now always get their shared libraries from 733 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 734 /usr/libsoft also existed). Only users with a hard-float ld.so, but 735 soft-float everything else should be affected. 736 73720170826: 738 The geli password typed at boot is now hidden. To restore the previous 739 behavior, see geli(8) for configuration options. 740 74120170825: 742 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 743 sysctl values. Minor nit, but requires a rebuild of both world/kernel 744 to complete. 745 74620170814: 747 "make check" behavior (made in ^/head@r295380) has been changed to 748 execute from a limited sandbox, as opposed to executing from 749 ${TESTSDIR}. 750 751 Behavioral changes: 752 - The "beforecheck" and "aftercheck" targets are now specified. 753 - ${CHECKDIR} (added in commit noted above) has been removed. 754 - Legacy behavior can be enabled by setting 755 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 756 757 If the limited sandbox mode is enabled, "make check" will execute 758 "make distribution", then install, execute the tests, and clean up the 759 sandbox if successful. 760 761 The "make distribution" and "make install" targets are typically run as 762 root to set appropriate permissions and ownership at installation time. 763 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 764 environment if executing "make check" with limited sandbox mode using 765 an unprivileged user. 766 76720170808: 768 Since the switch to GPT disk labels, fsck for UFS/FFS has been 769 unable to automatically find alternate superblocks. As of r322297, 770 the information needed to find alternate superblocks has been 771 moved to the end of the area reserved for the boot block. 772 Filesystems created with a newfs of this vintage or later 773 will create the recovery information. If you have a filesystem 774 created prior to this change and wish to have a recovery block 775 created for your filesystem, you can do so by running fsck in 776 foreground mode (i.e., do not use the -p or -y options). As it 777 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 778 to which you should answer yes. 779 78020170728: 781 As of r321665, an NFSv4 server configuration that services 782 Kerberos mounts or clients that do not support the uid/gid in 783 owner/owner_group string capability, must explicitly enable 784 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 785 machine's /etc/rc.conf file. 786 78720170722: 788 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 789 Please see the 20141231 entry below for information about prerequisites 790 and upgrading, if you are not already using clang 3.5.0 or higher. 791 79220170701: 793 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 794 r-commands (rlogin, rsh, etc.) to be built with the base system. 795 79620170625: 797 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 798 a very major ABI incompatible change, so users of FreeBSD/powerpc must 799 be careful when performing source upgrades. It is best to run 800 'make installworld' from an alternate root system, either a live 801 CD/memory stick, or a temporary root partition. Additionally, all ports 802 must be recompiled. powerpc64 is largely unaffected, except in the case 803 of 32-bit compatibility. All 32-bit binaries will be affected. 804 80520170623: 806 Forward compatibility for the "ino64" project have been committed. This 807 will allow most new binaries to run on older kernels in a limited 808 fashion. This prevents many of the common foot-shooting actions in the 809 upgrade as well as the limited ability to roll back the kernel across 810 the ino64 upgrade. Complicated use cases may not work properly, though 811 enough simpler ones work to allow recovery in most situations. 812 81320170620: 814 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 815 if you require the GPL compiler. 816 81720170618: 818 The internal ABI used for communication between the NFS kernel modules 819 was changed by r320085, so __FreeBSD_version was bumped to 820 ensure all the NFS related modules are updated together. 821 82220170617: 823 The ABI of struct event was changed by extending the data 824 member to 64bit and adding ext fields. For upgrade, same 825 precautions as for the entry 20170523 "ino64" must be 826 followed. 827 82820170531: 829 The GNU roff toolchain has been removed from base. To render manpages 830 which are not supported by mandoc(1), man(1) can fallback on GNU roff 831 from ports (and recommends to install it). 832 To render roff(7) documents, consider using GNU roff from ports or the 833 heirloom doctools roff toolchain from ports via pkg install groff or 834 via pkg install heirloom-doctools. 835 83620170524: 837 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 838 smaller runtime footprint builds. This is useful for embedded systems 839 which only require one chipset support. 840 841 If you load it as a module, make sure this is in /boot/loader.conf: 842 843 if_ath_load="YES" 844 845 This will load the HAL, all chip/RF backends and if_ath_pci. 846 If you have if_ath_pci in /boot/loader.conf, ensure it is after 847 if_ath or it will not load any HAL chipset support. 848 849 If you want to selectively load things (eg on ye cheape ARM/MIPS 850 platforms where RAM is at a premium) you should: 851 852 * load ath_hal 853 * load the chip modules in question 854 * load ath_rate, ath_dfs 855 * load ath_main 856 * load if_ath_pci and/or if_ath_ahb depending upon your particular 857 bus bind type - this is where probe/attach is done. 858 859 For further comments/feedback, poke adrian@ . 860 86120170523: 862 The "ino64" 64-bit inode project has been committed, which extends 863 a number of types to 64 bits. Upgrading in place requires care and 864 adherence to the documented upgrade procedure. 865 866 If using a custom kernel configuration ensure that the 867 COMPAT_FREEBSD11 option is included (as during the upgrade the 868 system will be running the ino64 kernel with the existing world). 869 870 For the safest in-place upgrade begin by removing previous build 871 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the 872 full procedure documented below under the heading "To rebuild 873 everything and install it on the current system." Specifically, 874 a reboot is required after installing the new kernel before 875 installing world. 876 87720170424: 878 The NATM framework including the en(4), fatm(4), hatm(4), and 879 patm(4) devices has been removed. Consumers should plan a 880 migration before the end-of-life date for FreeBSD 11. 881 88220170420: 883 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 884 diff has not been implemented, if those are needed a newer version of 885 GNU diff is available via the diffutils package under the gdiff name. 886 88720170413: 888 As of r316810 for ipfilter, keep frags is no longer assumed when 889 keep state is specified in a rule. r316810 aligns ipfilter with 890 documentation in man pages separating keep frags from keep state. 891 This allows keep state to be specified without forcing keep frags 892 and allows keep frags to be specified independently of keep state. 893 To maintain previous behaviour, also specify keep frags with 894 keep state (as documented in ipf.conf.5). 895 89620170407: 897 arm64 builds now use the base system LLD 4.0.0 linker by default, 898 instead of requiring that the aarch64-binutils port or package be 899 installed. To continue using aarch64-binutils, set 900 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 901 90220170405: 903 The UDP optimization in entry 20160818 that added the sysctl 904 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 905 packets will no longer be treated as L3 broadcast packets. 906 90720170331: 908 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 909 use any explicitly assigned loopback address available in the jail 910 instead of using the first assigned address of the jail. 911 91220170329: 913 The ctl.ko module no longer implements the iSCSI target frontend: 914 cfiscsi.ko does instead. 915 916 If building cfiscsi.ko as a kernel module, the module can be loaded 917 via one of the following methods: 918 - `cfiscsi_load="YES"` in loader.conf(5). 919 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 920 - ctladm(8)/ctld(8), when compiled with iSCSI support 921 (`WITH_ISCSI=yes` in src.conf(5)) 922 923 Please see cfiscsi(4) for more details. 924 92520170316: 926 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 927 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 928 same source (previously, the dependency of mmcsd.ko on mmc.ko was 929 missing, but mmcsd.ko now will refuse to load if it is incompatible 930 with mmc.ko). 931 93220170315: 933 The syntax of ipfw(8) named states was changed to avoid ambiguity. 934 If you have used named states in the firewall rules, you need to modify 935 them after installworld and before rebooting. Now named states must 936 be prefixed with colon. 937 93820170311: 939 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 940 removed as the userland we provide cannot use them. The KMS version 941 (sys/dev/drm2) supports the same hardware. 942 94320170302: 944 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 945 Please see the 20141231 entry below for information about prerequisites 946 and upgrading, if you are not already using clang 3.5.0 or higher. 947 94820170221: 949 The code that provides support for ZFS .zfs/ directory functionality 950 has been reimplemented. It's not possible now to create a snapshot 951 by mkdir under .zfs/snapshot/. That should be the only user visible 952 change. 953 95420170216: 955 EISA bus support has been removed. The WITH_EISA option is no longer 956 valid. 957 95820170215: 959 MCA bus support has been removed. 960 96120170127: 962 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 963 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 964 96520170112: 966 The EM_MULTIQUEUE kernel configuration option is deprecated now that 967 the em(4) driver conforms to iflib specifications. 968 96920170109: 970 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 971 IFLIB. If you have a custom kernel configuration that excludes em(4) 972 but you use igb(4), you need to re-add em(4) to your custom configuration. 973 97420161217: 975 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 976 Please see the 20141231 entry below for information about prerequisites 977 and upgrading, if you are not already using clang 3.5.0 or higher. 978 97920161124: 980 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 981 Please see the 20141231 entry below for information about prerequisites 982 and upgrading, if you are not already using clang 3.5.0 or higher. 983 98420161119: 985 The layout of the pmap structure has changed for powerpc to put the pmap 986 statistics at the front for all CPU variations. libkvm(3) and all tools 987 that link against it need to be recompiled. 988 98920161030: 990 isl(4) and cyapa(4) drivers now require a new driver, 991 chromebook_platform(4), to work properly on Chromebook-class hardware. 992 On other types of hardware the drivers may need to be configured using 993 device hints. Please see the corresponding manual pages for details. 994 99520161017: 996 The urtwn(4) driver was merged into rtwn(4) and now consists of 997 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 998 parts. 999 Also, firmware for RTL8188CE was renamed due to possible name 1000 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 1001 100220161015: 1003 GNU rcs has been removed from base. It is available as packages: 1004 - rcs: Latest GPLv3 GNU rcs version. 1005 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 1006 removed from base. 1007 100820161008: 1009 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 1010 modules now requires that the kernel configuration contain the 1011 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 1012 101320161003: 1014 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 1015 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 1016 101720160924: 1018 Relocatable object files with the extension of .So have been renamed 1019 to use an extension of .pico instead. The purpose of this change is 1020 to avoid a name clash with shared libraries on case-insensitive file 1021 systems. On those file systems, foo.So is the same file as foo.so. 1022 102320160918: 1024 GNU rcs has been turned off by default. It can (temporarily) be built 1025 again by adding WITH_RCS knob in src.conf. 1026 Otherwise, GNU rcs is available from packages: 1027 - rcs: Latest GPLv3 GNU rcs version. 1028 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 1029 103020160918: 1031 The backup_uses_rcs functionality has been removed from rc.subr. 1032 103320160908: 1034 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1035 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1036 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1037 QUEUE_MACRO_DEBUG behavior. 1038 103920160824: 1040 r304787 changed some ioctl interfaces between the iSCSI userspace 1041 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1042 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1043 to 1200005. 1044 104520160818: 1046 The UDP receive code has been updated to only treat incoming UDP 1047 packets that were addressed to an L2 broadcast address as L3 1048 broadcast packets. It is not expected that this will affect any 1049 standards-conforming UDP application. The new behaviour can be 1050 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1051 0. 1052 105320160818: 1054 Remove the openbsd_poll system call. 1055 __FreeBSD_version has been bumped because of this. 1056 105720160708: 1058 The stable/11 branch has been created from head@r302406. 1059 106020160622: 1061 The libc stub for the pipe(2) system call has been replaced with 1062 a wrapper that calls the pipe2(2) system call and the pipe(2) 1063 system call is now only implemented by the kernels that include 1064 "options COMPAT_FREEBSD10" in their config file (this is the 1065 default). Users should ensure that this option is enabled in 1066 their kernel or upgrade userspace to r302092 before upgrading their 1067 kernel. 1068 106920160527: 1070 CAM will now strip leading spaces from SCSI disks' serial numbers. 1071 This will affect users who create UFS filesystems on SCSI disks using 1072 those disk's diskid device nodes. For example, if /etc/fstab 1073 previously contained a line like 1074 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 1075 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 1076 transforms like gmirror may also be affected. ZFS users should 1077 generally be fine. 1078 107920160523: 1080 The bitstring(3) API has been updated with new functionality and 1081 improved performance. But it is binary-incompatible with the old API. 1082 Objects built with the new headers may not be linked against objects 1083 built with the old headers. 1084 108520160520: 1086 The brk and sbrk functions have been removed from libc on arm64. 1087 Binutils from ports has been updated to not link to these 1088 functions and should be updated to the latest version before 1089 installing a new libc. 1090 109120160517: 1092 The armv6 port now defaults to hard float ABI. Limited support 1093 for running both hardfloat and soft float on the same system 1094 is available using the libraries installed with -DWITH_LIBSOFT. 1095 This has only been tested as an upgrade path for installworld 1096 and packages may fail or need manual intervention to run. New 1097 packages will be needed. 1098 1099 To update an existing self-hosted armv6hf system, you must add 1100 TARGET_ARCH=armv6 on the make command line for both the build 1101 and the install steps. 1102 110320160510: 1104 Kernel modules compiled outside of a kernel build now default to 1105 installing to /boot/modules instead of /boot/kernel. Many kernel 1106 modules built this way (such as those in ports) already overrode 1107 KMODDIR explicitly to install into /boot/modules. However, 1108 manually building and installing a module from /sys/modules will 1109 now install to /boot/modules instead of /boot/kernel. 1110 111120160414: 1112 The CAM I/O scheduler has been committed to the kernel. There should be 1113 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1114 list of known rogues that claim support for this but actually corrupt 1115 data is believed to be complete, be on the lookout for data 1116 corruption. The known rogue list is believed to be complete: 1117 1118 o Crucial MX100, M550 drives with MU01 firmware. 1119 o Micron M510 and M550 drives with MU01 firmware. 1120 o Micron M500 prior to MU07 firmware 1121 o Samsung 830, 840, and 850 all firmwares 1122 o FCCT M500 all firmwares 1123 1124 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1125 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1126 updated firmware. Black listed drives will work correctly because these 1127 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1128 this list is the same as found in Linux, it's believed there are no 1129 other rogues in the market place. All other models from the above 1130 vendors work. 1131 1132 To be safe, if you are at all concerned, you can quirk each of your 1133 drives to prevent NCQ from being sent by setting: 1134 kern.cam.ada.X.quirks="0x2" 1135 in loader.conf. If the drive requires the 4k sector quirk, set the 1136 quirks entry to 0x3. 1137 113820160330: 1139 The FAST_DEPEND build option has been removed and its functionality is 1140 now the one true way. The old mkdep(1) style of 'make depend' has 1141 been removed. See 20160311 for further details. 1142 114320160317: 1144 Resource range types have grown from unsigned long to uintmax_t. All 1145 drivers, and anything using libdevinfo, need to be recompiled. 1146 114720160311: 1148 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1149 builds. It no longer runs mkdep(1) during 'make depend', and the 1150 'make depend' stage can safely be skipped now as it is auto ran 1151 when building 'make all' and will generate all SRCS and DPSRCS before 1152 building anything else. Dependencies are gathered at compile time with 1153 -MF flags kept in separate .depend files per object file. Users should 1154 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1155 stale .depend files. 1156 115720160306: 1158 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1159 kernel modules. Therefore, if you load any kernel modules at boot time, 1160 please install the boot loaders after you install the kernel, but before 1161 rebooting, e.g.: 1162 1163 make buildworld 1164 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1165 make installkernel KERNCONF=YOUR_KERNEL_HERE 1166 make -C sys/boot install 1167 <reboot in single user> 1168 1169 Then follow the usual steps, described in the General Notes section, 1170 below. 1171 117220160305: 1173 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1174 see the 20141231 entry below for information about prerequisites and 1175 upgrading, if you are not already using clang 3.5.0 or higher. 1176 117720160301: 1178 The AIO subsystem is now a standard part of the kernel. The 1179 VFS_AIO kernel option and aio.ko kernel module have been removed. 1180 Due to stability concerns, asynchronous I/O requests are only 1181 permitted on sockets and raw disks by default. To enable 1182 asynchronous I/O requests on all file types, set the 1183 vfs.aio.enable_unsafe sysctl to a non-zero value. 1184 118520160226: 1186 The ELF object manipulation tool objcopy is now provided by the 1187 ELF Tool Chain project rather than by GNU binutils. It should be a 1188 drop-in replacement, with the addition of arm64 support. The 1189 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1190 to obtain the GNU version if necessary. 1191 119220160129: 1193 Building ZFS pools on top of zvols is prohibited by default. That 1194 feature has never worked safely; it's always been prone to deadlocks. 1195 Using a zvol as the backing store for a VM guest's virtual disk will 1196 still work, even if the guest is using ZFS. Legacy behavior can be 1197 restored by setting vfs.zfs.vol.recursive=1. 1198 119920160119: 1200 The NONE and HPN patches has been removed from OpenSSH. They are 1201 still available in the security/openssh-portable port. 1202 120320160113: 1204 With the addition of ypldap(8), a new _ypldap user is now required 1205 during installworld. "mergemaster -p" can be used to add the user 1206 prior to installworld, as documented in the handbook. 1207 120820151216: 1209 The tftp loader (pxeboot) now uses the option root-path directive. As a 1210 consequence it no longer looks for a pxeboot.4th file on the tftp 1211 server. Instead it uses the regular /boot infrastructure as with the 1212 other loaders. 1213 121420151211: 1215 The code to start recording plug and play data into the modules has 1216 been committed. While the old tools will properly build a new kernel, 1217 a number of warnings about "unknown metadata record 4" will be produced 1218 for an older kldxref. To avoid such warnings, make sure to rebuild 1219 the kernel toolchain (or world). Make sure that you have r292078 or 1220 later when trying to build 292077 or later before rebuilding. 1221 122220151207: 1223 Debug data files are now built by default with 'make buildworld' and 1224 installed with 'make installworld'. This facilitates debugging but 1225 requires more disk space both during the build and for the installed 1226 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1227 in src.conf(5). 1228 122920151130: 1230 r291527 changed the internal interface between the nfsd.ko and 1231 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1232 __FreeBSD_version has been bumped because of this. 1233 123420151108: 1235 Add support for unicode collation strings leads to a change of 1236 order of files listed by ls(1) for example. To get back to the old 1237 behaviour, set LC_COLLATE environment variable to "C". 1238 1239 Databases administrators will need to reindex their databases given 1240 collation results will be different. 1241 1242 Due to a bug in install(1) it is recommended to remove the ancient 1243 locales before running make installworld. 1244 1245 rm -rf /usr/share/locale/* 1246 124720151030: 1248 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1249 libcrypto.so.7 or libssl.so.7 must be recompiled. 1250 125120151020: 1252 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1253 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1254 should be replaced with isp_2400 and isp_2500 modules respectively. 1255 125620151017: 1257 The build previously allowed using 'make -n' to not recurse into 1258 sub-directories while showing what commands would be executed, and 1259 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1260 and 'make -N' will not. 1261 126220151012: 1263 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1264 and etcupdate will now use this file. A custom sendmail.cf is now 1265 updated via this mechanism rather than via installworld. If you had 1266 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1267 want to remove the exclusion or change it to "always install". 1268 /etc/mail/sendmail.cf is now managed the same way regardless of 1269 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1270 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1271 127220151011: 1273 Compatibility shims for legacy ATA device names have been removed. 1274 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1275 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1276 environment variables, /dev/ad* and /dev/ar* symbolic links. 1277 127820151006: 1279 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1280 Please see the 20141231 entry below for information about prerequisites 1281 and upgrading, if you are not already using clang 3.5.0 or higher. 1282 128320150924: 1284 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1285 and renamed from .symbols to .debug. This reduces the size requirements 1286 on the boot partition or file system and provides consistency with 1287 userland debug files. 1288 1289 When using the supported kernel installation method the 1290 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1291 as is done with /boot/kernel. 1292 1293 Developers wishing to maintain the historical behavior of installing 1294 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1295 129620150827: 1297 The wireless drivers had undergone changes that remove the 'parent 1298 interface' from the ifconfig -l output. The rc.d network scripts 1299 used to check presence of a parent interface in the list, so old 1300 scripts would fail to start wireless networking. Thus, etcupdate(3) 1301 or mergemaster(8) run is required after kernel update, to update your 1302 rc.d scripts in /etc. 1303 130420150827: 1305 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1306 These configurations are now automatically interpreted as 1307 'scrub fragment reassemble'. 1308 130920150817: 1310 Kernel-loadable modules for the random(4) device are back. To use 1311 them, the kernel must have 1312 1313 device random 1314 options RANDOM_LOADABLE 1315 1316 kldload(8) can then be used to load random_fortuna.ko 1317 or random_yarrow.ko. Please note that due to the indirect 1318 function calls that the loadable modules need to provide, 1319 the build-in variants will be slightly more efficient. 1320 1321 The random(4) kernel option RANDOM_DUMMY has been retired due to 1322 unpopularity. It was not all that useful anyway. 1323 132420150813: 1325 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1326 Control over building the ELF Tool Chain tools is now provided by 1327 the WITHOUT_TOOLCHAIN knob. 1328 132920150810: 1330 The polarity of Pulse Per Second (PPS) capture events with the 1331 uart(4) driver has been corrected. Prior to this change the PPS 1332 "assert" event corresponded to the trailing edge of a positive PPS 1333 pulse and the "clear" event was the leading edge of the next pulse. 1334 1335 As the width of a PPS pulse in a typical GPS receiver is on the 1336 order of 1 millisecond, most users will not notice any significant 1337 difference with this change. 1338 1339 Anyone who has compensated for the historical polarity reversal by 1340 configuring a negative offset equal to the pulse width will need to 1341 remove that workaround. 1342 134320150809: 1344 The default group assigned to /dev/dri entries has been changed 1345 from 'wheel' to 'video' with the id of '44'. If you want to have 1346 access to the dri devices please add yourself to the video group 1347 with: 1348 1349 # pw groupmod video -m $USER 1350 135120150806: 1352 The menu.rc and loader.rc files will now be replaced during 1353 upgrades. Please migrate local changes to menu.rc.local and 1354 loader.rc.local instead. 1355 135620150805: 1357 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1358 strings and strip have been removed. The src.conf(5) knob 1359 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1360 136120150728: 1362 As ZFS requires more kernel stack pages than is the default on some 1363 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1364 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1365 1366 Please consider using 'options KSTACK_PAGES=X' where X is greater 1367 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1368 136920150706: 1370 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1371 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1372 default, i.e., they will not contain "::". For example, instead 1373 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1374 to have a more specific match, such as different map entries for 1375 IPv6:0:0 vs IPv6:0. This change requires that configuration 1376 data (including maps, files, classes, custom ruleset, etc.) must 1377 use the same format, so make certain such configuration data is 1378 upgrading. As a very simple check search for patterns like 1379 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1380 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1381 the cf option UseCompressedIPv6Addresses. 1382 138320150630: 1384 The default kernel entropy-processing algorithm is now 1385 Fortuna, replacing Yarrow. 1386 1387 Assuming you have 'device random' in your kernel config 1388 file, the configurations allow a kernel option to override 1389 this default. You may choose *ONE* of: 1390 1391 options RANDOM_YARROW # Legacy /dev/random algorithm. 1392 options RANDOM_DUMMY # Blocking-only driver. 1393 1394 If you have neither, you get Fortuna. For most people, 1395 read no further, Fortuna will give a /dev/random that works 1396 like it always used to, and the difference will be irrelevant. 1397 1398 If you remove 'device random', you get *NO* kernel-processed 1399 entropy at all. This may be acceptable to folks building 1400 embedded systems, but has complications. Carry on reading, 1401 and it is assumed you know what you need. 1402 1403 *PLEASE* read random(4) and random(9) if you are in the 1404 habit of tweaking kernel configs, and/or if you are a member 1405 of the embedded community, wanting specific and not-usual 1406 behaviour from your security subsystems. 1407 1408 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1409 random', you will NOT have a functioning /dev/random, and 1410 many cryptographic features will not work, including SSH. 1411 You may also find strange behaviour from the random(3) set 1412 of library functions, in particular sranddev(3), srandomdev(3) 1413 and arc4random(3). The reason for this is that the KERN_ARND 1414 sysctl only returns entropy if it thinks it has some to 1415 share, and with RANDOM_DUMMY or no 'device random' this 1416 will never happen. 1417 141820150623: 1419 An additional fix for the issue described in the 20150614 sendmail 1420 entry below has been committed in revision 284717. 1421 142220150616: 1423 FreeBSD's old make (fmake) has been removed from the system. It is 1424 available as the devel/fmake port or via pkg install fmake. 1425 142620150615: 1427 The fix for the issue described in the 20150614 sendmail entry 1428 below has been committed in revision 284436. The work 1429 around described in that entry is no longer needed unless the 1430 default setting is overridden by a confDH_PARAMETERS configuration 1431 setting of '5' or pointing to a 512 bit DH parameter file. 1432 143320150614: 1434 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1435 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1436 and devel/kyua to version 0.20+ and adjust any calling code to work 1437 with Kyuafile and kyua. 1438 143920150614: 1440 The import of openssl to address the FreeBSD-SA-15:10.openssl 1441 security advisory includes a change which rejects handshakes 1442 with DH parameters below 768 bits. sendmail releases prior 1443 to 8.15.2 (not yet released), defaulted to a 512 bit 1444 DH parameter setting for client connections. To work around 1445 this interoperability, sendmail can be configured to use a 1446 2048 bit DH parameter by: 1447 1448 1. Edit /etc/mail/`hostname`.mc 1449 2. If a setting for confDH_PARAMETERS does not exist or 1450 exists and is set to a string beginning with '5', 1451 replace it with '2'. 1452 3. If a setting for confDH_PARAMETERS exists and is set to 1453 a file path, create a new file with: 1454 openssl dhparam -out /path/to/file 2048 1455 4. Rebuild the .cf file: 1456 cd /etc/mail/; make; make install 1457 5. Restart sendmail: 1458 cd /etc/mail/; make restart 1459 1460 A sendmail patch is coming, at which time this file will be 1461 updated. 1462 146320150604: 1464 Generation of legacy formatted entries have been disabled by default 1465 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1466 entries were converted to use the new format by default when the new, 1467 machine independent format have been added and supported since FreeBSD 1468 5.x. 1469 1470 Please see the pwd_mkdb(8) manual page for further details. 1471 147220150525: 1473 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1474 20141231 entry below for information about prerequisites and upgrading, 1475 if you are not already using 3.5.0 or higher. 1476 147720150521: 1478 TI platform code switched to using vendor DTS files and this update 1479 may break existing systems running on Beaglebone, Beaglebone Black, 1480 and Pandaboard: 1481 1482 - dtb files should be regenerated/reinstalled. Filenames are the 1483 same but content is different now 1484 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1485 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1486 addressing scheme is now pin 25 on /dev/gpioc3. 1487 - Pandaboard: /etc/ttys should be updated, serial console device is 1488 now /dev/ttyu2, not /dev/ttyu0 1489 149020150501: 1491 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1492 If you need the GNU extension from groff soelim(1), install groff 1493 from package: pkg install groff, or via ports: textproc/groff. 1494 149520150423: 1496 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1497 defined in symlink(7); previously symlinks were silently ignored. 1498 149920150415: 1500 The const qualifier has been removed from iconv(3) to comply with 1501 POSIX. The ports tree is aware of this from r384038 onwards. 1502 150320150416: 1504 Libraries specified by LIBADD in Makefiles must have a corresponding 1505 DPADD_<lib> variable to ensure correct dependencies. This is now 1506 enforced in src.libnames.mk. 1507 150820150324: 1509 From legacy ata(4) driver was removed support for SATA controllers 1510 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1511 Kernel modules ataahci and ataadaptec were removed completely, 1512 replaced by ahci and mvs modules respectively. 1513 151420150315: 1515 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1516 the 20141231 entry below for information about prerequisites and 1517 upgrading, if you are not already using 3.5.0 or higher. 1518 151920150307: 1520 The 32-bit PowerPC kernel has been changed to a position-independent 1521 executable. This can only be booted with a version of loader(8) 1522 newer than January 31, 2015, so make sure to update both world and 1523 kernel before rebooting. 1524 152520150217: 1526 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1527 but before r278950, the RNG was not seeded properly. Immediately 1528 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1529 ssh keys or openssl keys) that were generated w/ a kernel from that 1530 range. This does not affect programs that directly used /dev/random 1531 or /dev/urandom. All userland uses of arc4random(3) are affected. 1532 153320150210: 1534 The autofs(4) ABI was changed in order to restore binary compatibility 1535 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1536 with the new kernel. 1537 153820150131: 1539 The powerpc64 kernel has been changed to a position-independent 1540 executable. This can only be booted with a new version of loader(8), 1541 so make sure to update both world and kernel before rebooting. 1542 154320150118: 1544 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1545 only release, no new features have been added. Please see the 20141231 1546 entry below for information about prerequisites and upgrading, if you 1547 are not already using 3.5.0. 1548 154920150107: 1550 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1551 taken from the ELF Tool Chain project rather than GNU binutils. They 1552 should be drop-in replacements, with the addition of arm64 support. 1553 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1554 binutils tools, if necessary. See 20150805 for updated information. 1555 155620150105: 1557 The default Unbound configuration now enables remote control 1558 using a local socket. Users who have already enabled the 1559 local_unbound service should regenerate their configuration 1560 by running "service local_unbound setup" as root. 1561 156220150102: 1563 The GNU texinfo and GNU info pages have been removed. 1564 To be able to view GNU info pages please install texinfo from ports. 1565 156620141231: 1567 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1568 1569 As of this release, a prerequisite for building clang, llvm and lldb is 1570 a C++11 capable compiler and C++11 standard library. This means that to 1571 be able to successfully build the cross-tools stage of buildworld, with 1572 clang as the bootstrap compiler, your system compiler or cross compiler 1573 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1574 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1575 later. 1576 1577 On any standard FreeBSD 10.x or 11.x installation, where clang and 1578 libc++ are on by default (that is, on x86 or arm), this should work out 1579 of the box. 1580 1581 On 9.x installations where clang is enabled by default, e.g. on x86 and 1582 powerpc, libc++ will not be enabled by default, so libc++ should be 1583 built (with clang) and installed first. If both clang and libc++ are 1584 missing, build clang first, then use it to build libc++. 1585 1586 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1587 the instructions for 9.x above. 1588 1589 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1590 default, and do not build clang. 1591 1592 Many embedded systems are resource constrained, and will not be able to 1593 build clang in a reasonable time, or in some cases at all. In those 1594 cases, cross building bootable systems on amd64 is a workaround. 1595 1596 This new version of clang introduces a number of new warnings, of which 1597 the following are most likely to appear: 1598 1599 -Wabsolute-value 1600 1601 This warns in two cases, for both C and C++: 1602 * When the code is trying to take the absolute value of an unsigned 1603 quantity, which is effectively a no-op, and almost never what was 1604 intended. The code should be fixed, if at all possible. If you are 1605 sure that the unsigned quantity can be safely cast to signed, without 1606 loss of information or undefined behavior, you can add an explicit 1607 cast, or disable the warning. 1608 1609 * When the code is trying to take an absolute value, but the called 1610 abs() variant is for the wrong type, which can lead to truncation. 1611 If you want to disable the warning instead of fixing the code, please 1612 make sure that truncation will not occur, or it might lead to unwanted 1613 side-effects. 1614 1615 -Wtautological-undefined-compare and 1616 -Wundefined-bool-conversion 1617 1618 These warn when C++ code is trying to compare 'this' against NULL, while 1619 'this' should never be NULL in well-defined C++ code. However, there is 1620 some legacy (pre C++11) code out there, which actively abuses this 1621 feature, which was less strictly defined in previous C++ versions. 1622 1623 Squid and openjdk do this, for example. The warning can be turned off 1624 for C++98 and earlier, but compiling the code in C++11 mode might result 1625 in unexpected behavior; for example, the parts of the program that are 1626 unreachable could be optimized away. 1627 162820141222: 1629 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1630 kernel sources have been removed. The .h files remain, since some 1631 utilities include them. This will need to be fixed later. 1632 If "mount -t oldnfs ..." is attempted, it will fail. 1633 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1634 the utilities will report errors. 1635 163620141121: 1637 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1638 directories to top level SUBDIR variable when their parent 1639 directory is included in LOCAL_DIRS. Users with build systems with 1640 such hierarchies and without SUBDIR entries in the parent 1641 directory Makefiles should add them or add the directories to 1642 LOCAL_DIRS. 1643 164420141109: 1645 faith(4) and faithd(8) have been removed from the base system. Faith 1646 has been obsolete for a very long time. 1647 164820141104: 1649 vt(4), the new console driver, is enabled by default. It brings 1650 support for Unicode and double-width characters, as well as 1651 support for UEFI and integration with the KMS kernel video 1652 drivers. 1653 1654 You may need to update your console settings in /etc/rc.conf, 1655 most probably the keymap. During boot, /etc/rc.d/syscons will 1656 indicate what you need to do. 1657 1658 vt(4) still has issues and lacks some features compared to 1659 syscons(4). See the wiki for up-to-date information: 1660 https://wiki.freebsd.org/Newcons 1661 1662 If you want to keep using syscons(4), you can do so by adding 1663 the following line to /boot/loader.conf: 1664 kern.vty=sc 1665 166620141102: 1667 pjdfstest has been integrated into kyua as an opt-in test suite. 1668 Please see share/doc/pjdfstest/README for more details on how to 1669 execute it. 1670 167120141009: 1672 gperf has been removed from the base system for architectures 1673 that use clang. Ports that require gperf will obtain it from the 1674 devel/gperf port. 1675 167620140923: 1677 pjdfstest has been moved from tools/regression/pjdfstest to 1678 contrib/pjdfstest . 1679 168020140922: 1681 At svn r271982, The default linux compat kernel ABI has been adjusted 1682 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1683 update. If you wish to continue using the linux-f10 compat ports, 1684 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1685 encouraged to update their linux-compat packages to linux-c6 during 1686 their next update cycle. 1687 168820140729: 1689 The ofwfb driver, used to provide a graphics console on PowerPC when 1690 using vt(4), no longer allows mmap() of all physical memory. This 1691 will prevent Xorg on PowerPC with some ATI graphics cards from 1692 initializing properly unless x11-servers/xorg-server is updated to 1693 1.12.4_8 or newer. 1694 169520140723: 1696 The xdev targets have been converted to using TARGET and 1697 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1698 169920140719: 1700 The default unbound configuration has been modified to address 1701 issues with reverse lookups on networks that use private 1702 address ranges. If you use the local_unbound service, run 1703 "service local_unbound setup" as root to regenerate your 1704 configuration, then "service local_unbound reload" to load the 1705 new configuration. 1706 170720140709: 1708 The GNU texinfo and GNU info pages are not built and installed 1709 anymore, WITH_INFO knob has been added to allow to built and install 1710 them again. 1711 UPDATE: see 20150102 entry on texinfo's removal 1712 171320140708: 1714 The GNU readline library is now an INTERNALLIB - that is, it is 1715 statically linked into consumers (GDB and variants) in the base 1716 system, and the shared library is no longer installed. The 1717 devel/readline port is available for third party software that 1718 requires readline. 1719 172020140702: 1721 The Itanium architecture (ia64) has been removed from the list of 1722 known architectures. This is the first step in the removal of the 1723 architecture. 1724 172520140701: 1726 Commit r268115 has added NFSv4.1 server support, merged from 1727 projects/nfsv4.1-server. Since this includes changes to the 1728 internal interfaces between the NFS related modules, a full 1729 build of the kernel and modules will be necessary. 1730 __FreeBSD_version has been bumped. 1731 173220140629: 1733 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1734 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1735 which differs from the behaviour controlled by this knob.) 1736 173720140619: 1738 Maximal length of the serial number in CTL was increased from 16 to 1739 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1740 and ctld, need to be rebuilt to work with a new kernel. 1741 174220140606: 1743 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1744 1 respectively to match the upstream numbers. They were out of 1745 sync because, when they were originally added to FreeBSD, the 1746 upstream versions were not respected. These libraries are private 1747 and not yet built by default, so renumbering them should be a 1748 non-issue. However, unclean source trees will yield broken test 1749 programs once the operator executes "make delete-old-libs" after a 1750 "make installworld". 1751 1752 Additionally, the atf-sh binary was made private by moving it into 1753 /usr/libexec/. Already-built shell test programs will keep the 1754 path to the old binary so they will break after "make delete-old" 1755 is run. 1756 1757 If you are using WITH_TESTS=yes (not the default), wipe the object 1758 tree and rebuild from scratch to prevent spurious test failures. 1759 This is only needed once: the misnumbered libraries and misplaced 1760 binaries have been added to OptionalObsoleteFiles.inc so they will 1761 be removed during a clean upgrade. 1762 176320140512: 1764 Clang and llvm have been upgraded to 3.4.1 release. 1765 176620140508: 1767 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1768 be removed to avoid issues in the future (and has been added to 1769 ObsoleteFiles.inc). 1770 177120140505: 1772 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1773 past, it affected all builds that used the bsd.*.mk files. The old 1774 behavior was a bug, but people may have relied upon it. To get this 1775 behavior back, you can .include /etc/src.conf from /etc/make.conf 1776 (which is still global and isn't changed). This also changes the 1777 behavior of incremental builds inside the tree of individual 1778 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1779 Although this has survived make universe and some upgrade scenarios, 1780 other upgrade scenarios may have broken. At least one form of 1781 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1782 as well... In cases where MAKESYSPATH isn't working with this 1783 setting, you'll need to set it to the full path to your tree. 1784 1785 One side effect of all this cleaning up is that bsd.compiler.mk 1786 is no longer implicitly included by bsd.own.mk. If you wish to 1787 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1788 as well. 1789 179020140430: 1791 The lindev device has been removed since /dev/full has been made a 1792 standard device. __FreeBSD_version has been bumped. 1793 179420140424: 1795 The knob WITHOUT_VI was added to the base system, which controls 1796 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1797 in order to reorder files share/termcap and didn't build ex(1) as a 1798 build tool, so building/installing with WITH_VI is highly advised for 1799 build hosts for older releases. 1800 1801 This issue has been fixed in stable/9 and stable/10 in r277022 and 1802 r276991, respectively. 1803 180420140418: 1805 The YES_HESIOD knob has been removed. It has been obsolete for 1806 a decade. Please move to using WITH_HESIOD instead or your builds 1807 will silently lack HESIOD. 1808 180920140405: 1810 The uart(4) driver has been changed with respect to its handling 1811 of the low-level console. Previously the uart(4) driver prevented 1812 any process from changing the baudrate or the CLOCAL and HUPCL 1813 control flags. By removing the restrictions, operators can make 1814 changes to the serial console port without having to reboot. 1815 However, when getty(8) is started on the serial device that is 1816 associated with the low-level console, a misconfigured terminal 1817 line in /etc/ttys will now have a real impact. 1818 Before upgrading the kernel, make sure that /etc/ttys has the 1819 serial console device configured as 3wire without baudrate to 1820 preserve the previous behaviour. E.g: 1821 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1822 182320140306: 1824 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1825 to improve performance. To re-enable it, if needed, run rpcbind 1826 with command line option -W. 1827 182820140226: 1829 Switched back to the GPL dtc compiler due to updates in the upstream 1830 dts files not being supported by the BSDL dtc compiler. You will need 1831 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1832 may result while building dtb files during a kernel build if you fail 1833 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1834 183520140216: 1836 Clang and llvm have been upgraded to 3.4 release. 1837 183820140216: 1839 The nve(4) driver has been removed. Please use the nfe(4) driver 1840 for NVIDIA nForce MCP Ethernet adapters instead. 1841 184220140212: 1843 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1844 This could cause certain C++ applications using shared libraries built 1845 against the previous version of libc++ to crash. The incompatibility 1846 has now been fixed, but any C++ applications or shared libraries built 1847 between r261283 and r261801 should be recompiled. 1848 184920140204: 1850 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1851 capability mode support. Please note that enabling the feature in 1852 kernel is still highly recommended. 1853 185420140131: 1855 OpenSSH is now built with sandbox support, and will use sandbox as 1856 the default privilege separation method. This requires Capsicum 1857 capability mode support in kernel. 1858 185920140128: 1860 The libelf and libdwarf libraries have been updated to newer 1861 versions from upstream. Shared library version numbers for 1862 these two libraries were bumped. Any ports or binaries 1863 requiring these two libraries should be recompiled. 1864 __FreeBSD_version is bumped to 1100006. 1865 186620140110: 1867 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1868 instead of providing an explicit one, this would prevent such 1869 Makefile from providing its own Kyuafile in the future during 1870 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1871 intervention is needed to clean an objdir if you use NO_CLEAN: 1872 # find /usr/obj -name Kyuafile | xargs rm -f 1873 187420131213: 1875 The behavior of gss_pseudo_random() for the krb5 mechanism 1876 has changed, for applications requesting a longer random string 1877 than produced by the underlying enctype's pseudo-random() function. 1878 In particular, the random string produced from a session key of 1879 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1880 be different at the 17th octet and later, after this change. 1881 The counter used in the PRF+ construction is now encoded as a 1882 big-endian integer in accordance with RFC 4402. 1883 __FreeBSD_version is bumped to 1100004. 1884 188520131108: 1886 The WITHOUT_ATF build knob has been removed and its functionality 1887 has been subsumed into the more generic WITHOUT_TESTS. If you were 1888 using the former to disable the build of the ATF libraries, you 1889 should change your settings to use the latter. 1890 189120131025: 1892 The default version of mtree is nmtree which is obtained from 1893 NetBSD. The output is generally the same, but may vary 1894 slightly. If you found you need identical output adding 1895 "-F freebsd9" to the command line should do the trick. For the 1896 time being, the old mtree is available as fmtree. 1897 189820131014: 1899 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1900 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1901 1.1.4_8 and verify bsdyml not linked in, before running "make 1902 delete-old-libs": 1903 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1904 or 1905 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1906 190720131010: 1908 The stable/10 branch has been created in subversion from head 1909 revision r256279. 1910 1911COMMON ITEMS: 1912 1913 General Notes 1914 ------------- 1915 Avoid using make -j when upgrading. While generally safe, there are 1916 sometimes problems using -j to upgrade. If your upgrade fails with 1917 -j, please try again without -j. From time to time in the past there 1918 have been problems using -j with buildworld and/or installworld. This 1919 is especially true when upgrading between "distant" versions (eg one 1920 that cross a major release boundary or several minor releases, or when 1921 several months have passed on the -current branch). 1922 1923 Sometimes, obscure build problems are the result of environment 1924 poisoning. This can happen because the make utility reads its 1925 environment when searching for values for global variables. To run 1926 your build attempts in an "environmental clean room", prefix all make 1927 commands with 'env -i '. See the env(1) manual page for more details. 1928 1929 When upgrading from one major version to another it is generally best to 1930 upgrade to the latest code in the currently installed branch first, then 1931 do an upgrade to the new branch. This is the best-tested upgrade path, 1932 and has the highest probability of being successful. Please try this 1933 approach if you encounter problems with a major version upgrade. Since 1934 the stable 4.x branch point, one has generally been able to upgrade from 1935 anywhere in the most recent stable branch to head / current (or even the 1936 last couple of stable branches). See the top of this file when there's 1937 an exception. 1938 1939 When upgrading a live system, having a root shell around before 1940 installing anything can help undo problems. Not having a root shell 1941 around can lead to problems if pam has changed too much from your 1942 starting point to allow continued authentication after the upgrade. 1943 1944 This file should be read as a log of events. When a later event changes 1945 information of a prior event, the prior event should not be deleted. 1946 Instead, a pointer to the entry with the new information should be 1947 placed in the old entry. Readers of this file should also sanity check 1948 older entries before relying on them blindly. Authors of new entries 1949 should write them with this in mind. 1950 1951 ZFS notes 1952 --------- 1953 When upgrading the boot ZFS pool to a new version, always follow 1954 these two steps: 1955 1956 1.) recompile and reinstall the ZFS boot loader and boot block 1957 (this is part of "make buildworld" and "make installworld") 1958 1959 2.) update the ZFS boot block on your boot drive 1960 1961 The following example updates the ZFS boot block on the first 1962 partition (freebsd-boot) of a GPT partitioned drive ada0: 1963 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1964 1965 Non-boot pools do not need these updates. 1966 1967 To build a kernel 1968 ----------------- 1969 If you are updating from a prior version of FreeBSD (even one just 1970 a few days old), you should follow this procedure. It is the most 1971 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1972 1973 make kernel-toolchain 1974 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1975 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1976 1977 To test a kernel once 1978 --------------------- 1979 If you just want to boot a kernel once (because you are not sure 1980 if it works, or if you want to boot a known bad kernel to provide 1981 debugging information) run 1982 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1983 nextboot -k testkernel 1984 1985 To rebuild everything and install it on the current system. 1986 ----------------------------------------------------------- 1987 # Note: sometimes if you are running current you gotta do more than 1988 # is listed here if you are upgrading from a really old current. 1989 1990 <make sure you have good level 0 dumps> 1991 make buildworld 1992 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1993 make installkernel KERNCONF=YOUR_KERNEL_HERE 1994 [1] 1995 <reboot in single user> [3] 1996 mergemaster -Fp [5] 1997 make installworld 1998 mergemaster -Fi [4] 1999 make delete-old [6] 2000 <reboot> 2001 2002 To cross-install current onto a separate partition 2003 -------------------------------------------------- 2004 # In this approach we use a separate partition to hold 2005 # current's root, 'usr', and 'var' directories. A partition 2006 # holding "/", "/usr" and "/var" should be about 2GB in 2007 # size. 2008 2009 <make sure you have good level 0 dumps> 2010 <boot into -stable> 2011 make buildworld 2012 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2013 <maybe newfs current's root partition> 2014 <mount current's root partition on directory ${CURRENT_ROOT}> 2015 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 2016 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2017 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2018 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2019 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2020 <reboot into current> 2021 <do a "native" rebuild/install as described in the previous section> 2022 <maybe install compatibility libraries from ports/misc/compat*> 2023 <reboot> 2024 2025 2026 To upgrade in-place from stable to current 2027 ---------------------------------------------- 2028 <make sure you have good level 0 dumps> 2029 make buildworld [9] 2030 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 2031 make installkernel KERNCONF=YOUR_KERNEL_HERE 2032 [1] 2033 <reboot in single user> [3] 2034 mergemaster -Fp [5] 2035 make installworld 2036 mergemaster -Fi [4] 2037 make delete-old [6] 2038 <reboot> 2039 2040 Make sure that you've read the UPDATING file to understand the 2041 tweaks to various things you need. At this point in the life 2042 cycle of current, things change often and you are on your own 2043 to cope. The defaults can also change, so please read ALL of 2044 the UPDATING entries. 2045 2046 Also, if you are tracking -current, you must be subscribed to 2047 freebsd-current@freebsd.org. Make sure that before you update 2048 your sources that you have read and understood all the recent 2049 messages there. If in doubt, please track -stable which has 2050 much fewer pitfalls. 2051 2052 [1] If you have third party modules, such as vmware, you 2053 should disable them at this point so they don't crash your 2054 system on reboot. 2055 2056 [3] From the bootblocks, boot -s, and then do 2057 fsck -p 2058 mount -u / 2059 mount -a 2060 cd src 2061 adjkerntz -i # if CMOS is wall time 2062 Also, when doing a major release upgrade, it is required that 2063 you boot into single user mode to do the installworld. 2064 2065 [4] Note: This step is non-optional. Failure to do this step 2066 can result in a significant reduction in the functionality of the 2067 system. Attempting to do it by hand is not recommended and those 2068 that pursue this avenue should read this file carefully, as well 2069 as the archives of freebsd-current and freebsd-hackers mailing lists 2070 for potential gotchas. The -U option is also useful to consider. 2071 See mergemaster(8) for more information. 2072 2073 [5] Usually this step is a no-op. However, from time to time 2074 you may need to do this if you get unknown user in the following 2075 step. It never hurts to do it all the time. You may need to 2076 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2077 install) after the buildworld before this step if you last updated 2078 from current before 20130425 or from -stable before 20130430. 2079 2080 [6] This only deletes old files and directories. Old libraries 2081 can be deleted by "make delete-old-libs", but you have to make 2082 sure that no program is using those libraries anymore. 2083 2084 [8] The new kernel must be able to run existing binaries used by 2085 an installworld. When upgrading across major versions, the new 2086 kernel's configuration must include the correct COMPAT_FREEBSD<n> 2087 option for existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x 2088 binaries). Failure to do so may leave you with a system that is 2089 hard to boot to recover. A GENERIC kernel will include suitable 2090 compatibility options to run binaries from older branches. 2091 2092 Make sure that you merge any new devices from GENERIC since the 2093 last time you updated your kernel config file. 2094 2095 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2096 "?=" instead of the "=" assignment operator, so that buildworld can 2097 override the CPUTYPE if it needs to. 2098 2099 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2100 not on the command line, or in /etc/make.conf. buildworld will 2101 warn if it is improperly defined. 2102FORMAT: 2103 2104This file contains a list, in reverse chronological order, of major 2105breakages in tracking -current. It is not guaranteed to be a complete 2106list of such breakages, and only contains entries since September 23, 2011. 2107If you need to see UPDATING entries from before that date, you will need 2108to fetch an UPDATING file from an older FreeBSD release. 2109 2110Copyright information: 2111 2112Copyright 1998-2009 M.
