1Release notes for FreeBSD 15.0. 2 3This file describes new user-visible features, changes and updates relevant to 4users of binary FreeBSD releases. Each entry should describe the change in no 5more than several sentences and should reference manual pages where an 6interested user can find more information. Entries should wrap after 80 7columns. Each entry should begin with one or more commit IDs on one line, 8specified as a comma separated list and/or range, followed by a colon and a 9newline. Entries should be separated by a newline. 10 11Changes to this file should not be MFCed. 12 13dc5ba6b8b4f0: 14 The WITHOUT_GSSAPI src.conf(5) option has been removed. The GSSAPI 15 libraries are now always built unless WITHOUT_KERBEROS is set. 16 17c43cad871720: 18 jemalloc 5.3.0 has landed. See contrib/jemalloc/ChangeLog 19 for the long list of changes. 20 21cce64f2e6851: 22 Add support for the NFSv4.2 Clone operation, which uses 23 block cloning to "copy on write" files on an NFS server. 24 This only works for exported ZFS file systems that have 25 block cloning enabled, at this time. 26 2737b2cb5ecb0f: 28 Add support to VOP_COPY_FILE_RANGE() for block cloning. 29 At this time, ZFS is the only local file system that supports 30 this and only if block cloning is enabled. NFSv4.2 also supports it. 31 See pathconf(2) and copy_file_range(2) for more information. 32 332ec2ba7e232d, df58e8b1506f (openzfs 2957eabbe), f61844833ee8, b1b607bd200f, 34 ee95e4d02dbd: 35 Add Solaris style extended attributes (called named attributes 36 in NFSv4). At this time, only ZFS when the ZFS property called 37 xattr=dir and NFSv4 support them. The attributes are presented 38 in a directory as regular files. See named_attribute(7) for 39 more information. 40 41ef2a572bf6: 42 Inline IPSEC offload infrastructure and driver support for mlx5(4) 43 Nvidia ConnectX-6+ network cards were added. 44 4568ba38dad3: 46 amd64: handling of the %fsbase/%gsbase registers and tls base 47 were reworked, making it more useful for apps that directly 48 manipulate CPU context. 49 5078aaab9f1cf: 51 rtld: added support for -z initfirst 52 53e36f069ecb4, c069ca085b: 54 Reliability of UFS on volumes with more than 2G of inodes is 55 significantly improved. The underlying issue was the invalid 56 interpretation of the 32bit inode number as signed, which got 57 sign-extended into ino_t. 58 59d390633cf8c: 60 On modern amd64 machines (which have the LA57 CPU feature), 61 FreeBSD is able to utilize more than 4TB of RAM. 62 632bd157bc732a: 64 The readdir_r(3) function is deprecated and may be removed in future 65 releases. Using it in a program will result in compile-time and 66 link-time warnings. 67 689ba51cce8bbd: 69 bsnmpd(1) no longer supports legacy UDP transport. Users, that have 70 not updated their /etc/snmpd.config since 12.0-RELEASE or older will 71 need to merge in the new configuration. In particular, the transport 72 definition shall be changed from begemotSnmpdPortStatus OID to 73 begemotSnmpdTransInetStatus. 74 751349a733cf28: 76 Add a driver supporting a new storage controller interface, 77 Universal Flash Storage Host Controller Interface, supporting 78 version 4.1 and earlier, via ufshci(4). 79 80f1f230439fa4: 81 FreeBSD now implements the inotify(2) family of system calls. 82 8350e733f19b37, 171f66b0c2ca: 84 These commits helped improve utilization of NFSv4.1/4.2 85 delegations. The changes are only used when the NFSv4 86 mount uses the "nocto" mount option and requires an 87 up-to-date NFSv4.1/4.2 server with delegations enabled. 88 For example: For a FreeBSD kernel build with both src 89 and obj NFSv4 mounted, the total RPC count dropped from 90 5461286 to 945643, with a 20% drop in elapsed time. 91 92c3fc0db3bc50 93 The default value of the sysctl variable 94 net.inet.tcp.nolocaltimewait has changed from 1 to 0. This means 95 that FreeBSD does not skip the TIME_WAIT state anymore for 96 endpoints for which the remote address is local. The new sysctl 97 variable net.inet.tcp.msl_local can be used to control the time 98 these endpoints stay in the TIME_WAIT state. The sysctl variable 99 net.inet.tcp.nolocaltimewait is deprecated and intended to be 100 removed in FreeBSD 16. 101 102cd240957d7ba 103 Making a connection to INADDR_ANY (i.e., using INADDR_ANY as an alias 104 for localhost) is now disabled by default. This functionality can be 105 re-enabled by setting the net.inet.ip.connect_inaddr_wild sysctl to 1. 106 107b61850c4e6f6 108 The bridge(4) sysctl net.link.bridge.member_ifaddrs now defaults to 0, 109 meaning that interfaces added to a bridge may not have IP addresses 110 assigned. Refer to bridge(4) for more information. 111 11244e5a0150835, 9a37f1024ceb: 113 A new utility sndctl(8) has been added to concentrate the various 114 interfaces for viewing and manipulating audio device settings (sysctls, 115 /dev/sndstat), into a single utility with a similar control-driven 116 interface to that of mixer(8). 117 11893a94ce731a8: 119 ps(1)'s options '-a' and '-A', when combined with any other one 120 affecting the selection of processes except for '-X' and '-x', would 121 have no effect, in contradiction with the rule that one process is 122 listed as soon as any of the specified options selects it (inclusive 123 OR), which is both mandated by POSIX and arguably a natural expectation. 124 This bug has been fixed. 125 126 As a practical consequence, specifying '-a'/'-A' now causes all 127 processes to be listed regardless of other selection options (except for 128 '-X' and '-x', which still apply). In particular, to list only 129 processes from specific jails, one must not use '-a' with '-J'. Option 130 '-J', contrary to its apparent initial intent, never worked as a filter 131 in practice (except by accident with '-a' due to the bug), but instead 132 as any other selection options (e.g., '-U', '-p', '-G', etc.) subject to 133 the "inclusive OR" rule. 134 135995b690d1398: 136 ps(1)'s '-U' option has been changed to select processes by their real 137 user IDs instead of their effective one, in accordance with POSIX and 138 the use case of wanting to list processes launched by some user, which 139 is expected to be more frequent than listing processes having the rights 140 of some user. This only affects the selection of processes whose real 141 and effective user IDs differ. After this change, ps(1)'s '-U' flag 142 behaves differently then in other BSDs but identically to that of 143 Linux's procps and illumos. 144 1451aabbb25c9f9: 146 ps(1)'s default list of processes now comes from matching its effective 147 user ID instead of its real user ID with the effective user ID of all 148 processes, in accordance with POSIX. As ps(1) itself is not installed 149 setuid, this only affects processes having different real and effective 150 user IDs that launch ps(1) processes. 151 152f0600c41e754-de701f9bdbe0, bc201841d139: 153 mac_do(4) is now considered production-ready and its functionality has 154 been considerably extended at the price of breaking credentials 155 transition rules' backwards compatibility. All that could be specified 156 with old rules can also be with new rules. Migrating old rules is just 157 a matter of adding "uid=" in front of the target part, substituting 158 commas (",") with semi-colons (";") and colons (":") with greater-than 159 signs (">"). Please consult the mac_do(4) manual page for the new rules 160 grammar. 161 16202d4eeabfd73: 163 hw.snd.maxautovchans has been retired. The commit introduced a 164 hw.snd.vchans_enable sysctl, which along with 165 dev.pcm.X.{play|rec}.vchans, from now on work as tunables to only 166 enable/disable vchans, as opposed to setting their number and/or 167 (de-)allocating vchans. Since these sysctls do not trigger any 168 (de-)allocations anymore, their effect is instantaneous, whereas before 169 we could have frozen the machine (when trying to allocate new vchans) 170 when setting dev.pcm.X.{play|rec}.vchans to a very large value. 171 1727e7f88001d7d: 173 The definition of pf's struct pfr_tstats and struct pfr_astats has 174 changed, breaking ABI compatibility for 32-bit powerpc (including 175 powerpcspe) and armv7. Users of these platforms should ensure kernel 176 and userspace are updated together. 177 1785dc99e9bb985, 08e638c089a, 4009a98fe80: 179 The net.inet.{tcp,udp,raw}.bind_all_fibs tunables have been added. 180 They modify socket behavior such that packets not originating from the 181 same FIB as the socket are ignored. TCP and UDP sockets belonging to 182 different FIBs may also be bound to the same address. The default 183 behavior is unmodified. 184 185f87bb5967670, e51036fbf3f8: 186 Support for vinum volumes has been removed. 187 1888ae6247aa966, cf0ede720391d, 205659c43d87bd, 1ccbdf561f417, 4db1b113b151: 189 The layout of NFS file handles for the tarfs, tmpfs, cd9660, and ext2fs 190 file systems has changed. An NFS server that exports any of these file 191 systems will need its clients to unmount and remount the exports. 192 1931111a44301da: 194 Defer the January 19, 2038 date limit in UFS1 filesystems to 195 February 7, 2106. This affects only UFS1 format filesystems. 196 See the commit message for details. 197 19807cd69e272da: 199 Add a new -a command line option to mountd(8). 200 If this command line option is specified, when 201 a line in exports(5) has the -alldirs export option, 202 the directory must be a server file system mount point. 203 2040e8a36a2ab12: 205 Add a new NFS mount option called "mountport" that may be used 206 to specify the port# for the NFS server's Mount protocol. 207 This permits a NFSv3 mount to be done without running rpcbind(8). 208 209b2f7c53430c3: 210 Kernel TLS is now enabled by default in kernels including KTLS 211 support. KTLS is included in GENERIC kernels for aarch64, 212 amd64, powerpc64, and powerpc64le. 213 214f57efe95cc25: 215 New mididump(1) utility which dumps MIDI 1.0 events in real time. 216 217ddfc6f84f242: 218 Update unicode to 16.0.0 and CLDR to 45.0.0. 219 220b22be3bbb2de: 221 Basic Cloudinit images no longer generate RSA host keys by default for 222 SSH. 223 224000000000000: 225 RSA host keys for SSH are deprecated and will no longer be generated 226 by default in FreeBSD 16. 227 2280aabcd75dbc2: 229 EC2 AMIs no longer generate RSA host keys by default for SSH. RSA 230 host key generation can be re-enabled by setting sshd_rsa_enable="YES" 231 in /etc/rc.conf if it is necessary to support very old SSH clients. 232 233a1da7dc1cdad: 234 The SO_SPLICE socket option was added. It allows TCP connections to 235 be spliced together, enabling proxy-like functionality without the 236 need to copy data in and out of user memory. 237 238fc12c191c087: 239 grep(1) no longer follows symbolic links by default for 240 recursive searches. This matches the documented behavior in 241 the manual page. 242 243e962b37bf0ff: 244 When running bhyve(8) guests with a boot ROM, i.e., bhyveload(8) is not 245 used, bhyve now assumes that the boot ROM will enable PCI BAR decoding. 246 This is incompatible with some boot ROMs, particularly outdated builds 247 of edk2-bhyve. To restore the old behavior, add 248 "pci.enable_bars='true'" to your bhyve configuration. 249 250 Note in particular that the uefi-edk2-bhyve package has been renamed 251 to edk2-bhyve. 252 25343caa2e805c2: 254 amd64 bhyve(8)'s "lpc.bootrom" and "lpc.bootvars" options are 255 deprecated. Use the top-level "bootrom" and "bootvars" options 256 instead. 257 258822ca3276345: 259 byacc was updated to 20240109. 260 26121817992b331: 262 ncurses was updated to 6.5. 263 2641687d77197c0: 265 Filesystem manual pages have been moved to section four. 266 Please check ports you are maintaining for crossreferences. 267 2688aac90f18aef: 269 new MAC/do policy and mdo(1) utility which enables a user to 270 become another user without the requirement of setuid root. 271 2727398d1ece5cf: 273 hw.snd.version is removed. 274 275a15f7c96a276,66b5296f1b29: 276 NVMe over Fabrics controller. The nvmft(4) kernel module adds 277 a new frontend to the CAM target layer which exports ctl(4) 278 LUNs as NVMe namespaces to remote hosts. The ctld(8) daemon 279 now supports NVMe controllers in addition to iSCSI targets and 280 is responsible for accepting incoming connection requests and 281 handing off connected queue pairs to nvmft(4). 282 283a1eda74167b5,1058c12197ab: 284 NVMe over Fabrics host. New commands added to nvmecontrol(8) 285 to establish connections to remote controllers. Once 286 connections are established they are handed off to the nvmf(4) 287 kernel module which creates nvmeX devices and exports remote 288 namespaces as nda(4) disks. 289 29025723d66369f: 291 As a side-effect of retiring the unit.* code in sound(4), the 292 hw.snd.maxunit loader(8) tunable is also retired. 293 294eeb04a736cb9: 295 date(1) now supports nanoseconds. For example: 296 `date -Ins` prints "2024-04-22T12:20:28,763742224+02:00" and 297 `date +%N` prints "415050400". 298 2996d5ce2bb6344: 300 The default value of the nfs_reserved_port_only rc.conf(5) setting has 301 changed. The FreeBSD NFS server now requires the source port of 302 requests to be in the privileged port range (i.e., <= 1023), which 303 generally requires the client to have elevated privileges on their local 304 system. The previous behavior can be restored by setting 305 nfs_reserved_port_only=NO in rc.conf. 306 307aea973501b19: 308 ktrace(2) will now record detailed information about capability mode 309 violations. The kdump(1) utility has been updated to display such 310 information. 311 312f32a6403d346: 313 One True Awk updated to 2nd Edition. See https://awk.dev for details 314 on the additions. Unicode and CSVs (Comma Separated Values) are now 315 supported. 316 317fe86d923f83f: 318 usbconfig(8) now reads the descriptions of the usb vendor and products 319 from usb.ids when available, similarly to what pciconf(8) does. 320 3214347ef60501f: 322 The powerd(8) utility is now enabled in /etc/rc.conf by default on 323 images for the arm64 Raspberry Pi's (arm64-aarch64-RPI img files). 324 This prevents the CPU clock from running slow all the time. 325 3260b49e504a32d: 327 rc.d/jail now supports the legacy variable jail_${jailname}_zfs_dataset 328 to allow unmaintained jail managers like ezjail to make use of this 329 feature (simply rename jail_${jailname}_zfs_datasets in the ezjail 330 config to jail_${jailname}_zfs_dataset. 331 332e0dfe185cbca: 333 jail(8) now support zfs.dataset to add a list of ZFS datasets to a 334 jail. 335 33661174ad88e33: 337 newsyslog(8) now supports specifying a global compression method directly 338 at the beginning of the newsyslog.conf file, which will make newsyslog(8) 339 to behave like the corresponding option was passed to the newly added 340 '-c' option. For example: 341 342 <compress> none 343 344906748d208d3: 345 newsyslog(8) now accepts a new option, '-c' which overrides all historical 346 compression flags by treating their meaning as "treat the file as compressible" 347 rather than "compress the file with that specific method." 348 349 The following choices are available: 350 * none: Do not compress, regardless of flag. 351 * legacy: Historical behavior (J=bzip2, X=xz, Y=zstd, Z=gzip). 352 * bzip2, xz, zstd, gzip: apply the specified compression method. 353 354 We plan to change the default to 'none' in FreeBSD 15.0. 355 3561a878807006c: 357 This commit added some statistics collection to the NFS-over-TLS 358 code in the NFS server so that sysadmins can moditor usage. 359 The statistics are available via the kern.rpc.tls.* sysctls. 360 3617c5146da1286: 362 Mountd has been modified to use strunvis(3) to decode directory 363 names in exports(5) file(s). This allows special characters, 364 such as blanks, to be embedded in the directory name(s). 365 "vis -M" may be used to encode such directory name(s). 366 367c5359e2af5ab: 368 bhyve(8) has a new network backend, "slirp", which makes use of the 369 libslirp package to provide a userspace network stack. This backend 370 makes it possible to access the guest network from the host without 371 requiring any extra network configuration on the host. 372 373bb830e346bd5: 374 Set the IUTF8 flag by default in tty(4). 375 376 128f63cedc14 and 9e589b093857 added proper UTF-8 backspacing handling 377 in the tty(4) driver, which is enabled by setting the new IUTF8 flag 378 through stty(1). Since the default locale is UTF-8, enable IUTF8 by 379 default. 380 381ff01d71e48d4: 382 dialog(1) has been replaced by bsddialog(1) 383 38441582f28ddf7: 385 FreeBSD 15.0 will not include support for 32-bit platforms. 386 However, 64-bit systems will still be able to run older 32-bit 387 binaries. 388 389 Support for executing 32-bit binaries on 64-bit platforms via 390 COMPAT_FREEBSD32 will remain supported for at least the 391 stable/15 and stable/16 branches. 392 393 Support for compiling individual 32-bit applications via 394 `cc -m32` will also be supported for at least the stable/15 395 branch which includes suitable headers in /usr/include and 396 libraries in /usr/lib32. 397 398 Support for 32-bit platforms in ports for 15.0 and later 399 releases is also deprecated, and these future releases may not 400 include binary packages for 32-bit platforms or support for 401 building 32-bit applications from ports. 402 403 stable/14 and earlier branches will retain existing 32-bit 404 kernel and world support. Ports will retain existing support 405 for building ports and packages for 32-bit systems on stable/14 406 and earlier branches as long as those branches are supported 407 by the ports system. However, all 32-bit platforms are Tier-2 408 or Tier-3 and support for individual ports should be expected 409 to degrade as upstreams deprecate 32-bit platforms. 410 411 With the current support schedule, stable/14 will be EOLed 5 412 years after the release of 14.0. The EOL of stable/14 would 413 mark the end of support for 32-bit platforms including source 414 releases, pre-built packages, and support for building 415 applications from ports. Given an estimated release date of 416 October 2023 for 14.0, support for 32-bit platforms would end 417 in October 2028. 418 419 The project may choose to alter this approach when 15.0 is 420 released by extending some level of 32-bit support for one or 421 more platforms in 15.0 or later. Users should use the 422 stable/14 branch to migrate off of 32-bit platforms. 423
