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 1302d4eeabfd73: 14 hw.snd.maxautovchans has been retired. The commit introduced a 15 hw.snd.vchans_enable sysctl, which along with 16 dev.pcm.X.{play|rec}.vchans, from now on work as tunables to only 17 enable/disable vchans, as opposed to setting their number and/or 18 (de-)allocating vchans. Since these sysctls do not trigger any 19 (de-)allocations anymore, their effect is instantaneous, whereas before 20 we could have frozen the machine (when trying to allocate new vchans) 21 when setting dev.pcm.X.{play|rec}.vchans to a very large value. 22 237e7f88001d7d: 24 The definition of pf's struct pfr_tstats and struct pfr_astats has 25 changed, breaking ABI compatibility for 32-bit powerpc (including 26 powerpcspe) and armv7. Users of these platforms should ensure kernel 27 and userspace are updated together. 28 295dc99e9bb985, 08e638c089a, 4009a98fe80: 30 The net.inet.{tcp,udp,raw}.bind_all_fibs tunables have been added. 31 They modify socket behavior such that packets not originating from the 32 same FIB as the socket are ignored. TCP and UDP sockets belonging to 33 different FIBs may also be bound to the same address. The default 34 behavior is unmodified. 35 36f87bb5967670, e51036fbf3f8: 37 Support for vinum volumes has been removed. 38 398ae6247aa966, cf0ede720391d, 205659c43d87bd, 1ccbdf561f417, 4db1b113b151: 40 The layout of NFS file handles for the tarfs, tmpfs, cd9660, and ext2fs 41 file systems has changed. An NFS server that exports any of these file 42 systems will need its clients to unmount and remount the exports. 43 441111a44301da: 45 Defer the January 19, 2038 date limit in UFS1 filesystems to 46 February 7, 2106. This affects only UFS1 format filesystems. 47 See the commit message for details. 48 4907cd69e272da: 50 Add a new -a command line option to mountd(8). 51 If this command line option is specified, when 52 a line in exports(5) has the -alldirs export option, 53 the directory must be a server file system mount point. 54 550e8a36a2ab12: 56 Add a new NFS mount option called "mountport" that may be used 57 to specify the port# for the NFS server's Mount protocol. 58 This permits a NFSv3 mount to be done without running rpcbind(8). 59 60b2f7c53430c3: 61 Kernel TLS is now enabled by default in kernels including KTLS 62 support. KTLS is included in GENERIC kernels for aarch64, 63 amd64, powerpc64, and powerpc64le. 64 65f57efe95cc25: 66 New mididump(1) utility which dumps MIDI 1.0 events in real time. 67 68ddfc6f84f242: 69 Update unicode to 16.0.0 and CLDR to 45.0.0. 70 71b22be3bbb2de: 72 Basic Cloudinit images no longer generate RSA host keys by default for 73 SSH. 74 75000000000000: 76 RSA host keys for SSH are deprecated and will no longer be generated 77 by default in FreeBSD 16. 78 790aabcd75dbc2: 80 EC2 AMIs no longer generate RSA host keys by default for SSH. RSA 81 host key generation can be re-enabled by setting sshd_rsa_enable="YES" 82 in /etc/rc.conf if it is necessary to support very old SSH clients. 83 84a1da7dc1cdad: 85 The SO_SPLICE socket option was added. It allows TCP connections to 86 be spliced together, enabling proxy-like functionality without the 87 need to copy data in and out of user memory. 88 89fc12c191c087: 90 grep(1) no longer follows symbolic links by default for 91 recursive searches. This matches the documented behavior in 92 the manual page. 93 94e962b37bf0ff: 95 When running bhyve(8) guests with a boot ROM, i.e., bhyveload(8) is not 96 used, bhyve now assumes that the boot ROM will enable PCI BAR decoding. 97 This is incompatible with some boot ROMs, particularly outdated builds 98 of edk2-bhyve. To restore the old behavior, add 99 "pci.enable_bars='true'" to your bhyve configuration. 100 101 Note in particular that the uefi-edk2-bhyve package has been renamed 102 to edk2-bhyve. 103 10443caa2e805c2: 105 amd64 bhyve(8)'s "lpc.bootrom" and "lpc.bootvars" options are 106 deprecated. Use the top-level "bootrom" and "bootvars" options 107 instead. 108 109822ca3276345: 110 byacc was updated to 20240109. 111 11221817992b331: 113 ncurses was updated to 6.5. 114 1151687d77197c0: 116 Filesystem manual pages have been moved to section four. 117 Please check ports you are maintaining for crossreferences. 118 1198aac90f18aef: 120 new MAC/do policy and mdo(1) utility which enables a user to 121 become another user without the requirement of setuid root. 122 1237398d1ece5cf: 124 hw.snd.version is removed. 125 126a15f7c96a276,a8089ea5aee5: 127 NVMe over Fabrics controller. The nvmft(4) kernel module adds 128 a new frontend to the CAM target layer which exports ctl(4) 129 LUNs as NVMe namespaces to remote hosts. The nvmfd(8) daemon 130 is responsible for accepting incoming connection requests and 131 handing off connected queue pairs to nvmft(4). 132 133a1eda74167b5,1058c12197ab: 134 NVMe over Fabrics host. New commands added to nvmecontrol(8) 135 to establish connections to remote controllers. Once 136 connections are established they are handed off to the nvmf(4) 137 kernel module which creates nvmeX devices and exports remote 138 namespaces as nda(4) disks. 139 14025723d66369f: 141 As a side-effect of retiring the unit.* code in sound(4), the 142 hw.snd.maxunit loader(8) tunable is also retired. 143 144eeb04a736cb9: 145 date(1) now supports nanoseconds. For example: 146 `date -Ins` prints "2024-04-22T12:20:28,763742224+02:00" and 147 `date +%N` prints "415050400". 148 1496d5ce2bb6344: 150 The default value of the nfs_reserved_port_only rc.conf(5) setting has 151 changed. The FreeBSD NFS server now requires the source port of 152 requests to be in the privileged port range (i.e., <= 1023), which 153 generally requires the client to have elevated privileges on their local 154 system. The previous behavior can be restored by setting 155 nfs_reserved_port_only=NO in rc.conf. 156 157aea973501b19: 158 ktrace(2) will now record detailed information about capability mode 159 violations. The kdump(1) utility has been updated to display such 160 information. 161 162f32a6403d346: 163 One True Awk updated to 2nd Edition. See https://awk.dev for details 164 on the additions. Unicode and CSVs (Comma Separated Values) are now 165 supported. 166 167fe86d923f83f: 168 usbconfig(8) now reads the descriptions of the usb vendor and products 169 from usb.ids when available, similarly to what pciconf(8) does. 170 1714347ef60501f: 172 The powerd(8) utility is now enabled in /etc/rc.conf by default on 173 images for the arm64 Raspberry Pi's (arm64-aarch64-RPI img files). 174 This prevents the CPU clock from running slow all the time. 175 1760b49e504a32d: 177 rc.d/jail now supports the legacy variable jail_${jailname}_zfs_dataset 178 to allow unmaintained jail managers like ezjail to make use of this 179 feature (simply rename jail_${jailname}_zfs_datasets in the ezjail 180 config to jail_${jailname}_zfs_dataset. 181 182e0dfe185cbca: 183 jail(8) now support zfs.dataset to add a list of ZFS datasets to a 184 jail. 185 18661174ad88e33: 187 newsyslog(8) now supports specifying a global compression method directly 188 at the beginning of the newsyslog.conf file, which will make newsyslog(8) 189 to behave like the corresponding option was passed to the newly added 190 '-c' option. For example: 191 192 <compress> none 193 194906748d208d3: 195 newsyslog(8) now accepts a new option, '-c' which overrides all historical 196 compression flags by treating their meaning as "treat the file as compressible" 197 rather than "compress the file with that specific method." 198 199 The following choices are available: 200 * none: Do not compress, regardless of flag. 201 * legacy: Historical behavior (J=bzip2, X=xz, Y=zstd, Z=gzip). 202 * bzip2, xz, zstd, gzip: apply the specified compression method. 203 204 We plan to change the default to 'none' in FreeBSD 15.0. 205 2061a878807006c: 207 This commit added some statistics collection to the NFS-over-TLS 208 code in the NFS server so that sysadmins can moditor usage. 209 The statistics are available via the kern.rpc.tls.* sysctls. 210 2117c5146da1286: 212 Mountd has been modified to use strunvis(3) to decode directory 213 names in exports(5) file(s). This allows special characters, 214 such as blanks, to be embedded in the directory name(s). 215 "vis -M" may be used to encode such directory name(s). 216 217c5359e2af5ab: 218 bhyve(8) has a new network backend, "slirp", which makes use of the 219 libslirp package to provide a userspace network stack. This backend 220 makes it possible to access the guest network from the host without 221 requiring any extra network configuration on the host. 222 223bb830e346bd5: 224 Set the IUTF8 flag by default in tty(4). 225 226 128f63cedc14 and 9e589b093857 added proper UTF-8 backspacing handling 227 in the tty(4) driver, which is enabled by setting the new IUTF8 flag 228 through stty(1). Since the default locale is UTF-8, enable IUTF8 by 229 default. 230 231ff01d71e48d4: 232 dialog(1) has been replaced by bsddialog(1) 233 23441582f28ddf7: 235 FreeBSD 15.0 will not include support for 32-bit platforms. 236 However, 64-bit systems will still be able to run older 32-bit 237 binaries. 238 239 Support for executing 32-bit binaries on 64-bit platforms via 240 COMPAT_FREEBSD32 will remain supported for at least the 241 stable/15 and stable/16 branches. 242 243 Support for compiling individual 32-bit applications via 244 `cc -m32` will also be supported for at least the stable/15 245 branch which includes suitable headers in /usr/include and 246 libraries in /usr/lib32. 247 248 Support for 32-bit platforms in ports for 15.0 and later 249 releases is also deprecated, and these future releases may not 250 include binary packages for 32-bit platforms or support for 251 building 32-bit applications from ports. 252 253 stable/14 and earlier branches will retain existing 32-bit 254 kernel and world support. Ports will retain existing support 255 for building ports and packages for 32-bit systems on stable/14 256 and earlier branches as long as those branches are supported 257 by the ports system. However, all 32-bit platforms are Tier-2 258 or Tier-3 and support for individual ports should be expected 259 to degrade as upstreams deprecate 32-bit platforms. 260 261 With the current support schedule, stable/14 will be EOLed 5 262 years after the release of 14.0. The EOL of stable/14 would 263 mark the end of support for 32-bit platforms including source 264 releases, pre-built packages, and support for building 265 applications from ports. Given an estimated release date of 266 October 2023 for 14.0, support for 32-bit platforms would end 267 in October 2028. 268 269 The project may choose to alter this approach when 15.0 is 270 released by extending some level of 32-bit support for one or 271 more platforms in 15.0 or later. Users should use the 272 stable/14 branch to migrate off of 32-bit platforms. 273
