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 137e7f88001d7d: 14 The definition of pf's struct pfr_tstats and struct pfr_astats has 15 changed, breaking ABI compatibility for 32-bit powerpc (including 16 powerpcspe) and armv7. Users of these platforms should ensure kernel 17 and userspace are updated together. 18 195dc99e9bb985, 08e638c089a, 4009a98fe80: 20 The net.inet.{tcp,udp,raw}.bind_all_fibs tunables have been added. 21 They modify socket behavior such that packets not originating from the 22 same FIB as the socket are ignored. TCP and UDP sockets belonging to 23 different FIBs may also be bound to the same address. The default 24 behavior is unmodified. 25 26f87bb5967670, e51036fbf3f8: 27 Support for vinum volumes has been removed. 28 298ae6247aa966, cf0ede720391d, 205659c43d87bd, 1ccbdf561f417, 4db1b113b151: 30 The layout of NFS file handles for the tarfs, tmpfs, cd9660, and ext2fs 31 file systems has changed. An NFS server that exports any of these file 32 systems will need its clients to unmount and remount the exports. 33 341111a44301da: 35 Defer the January 19, 2038 date limit in UFS1 filesystems to 36 February 7, 2106. This affects only UFS1 format filesystems. 37 See the commit message for details. 38 3907cd69e272da: 40 Add a new -a command line option to mountd(8). 41 If this command line option is specified, when 42 a line in exports(5) has the -alldirs export option, 43 the directory must be a server file system mount point. 44 450e8a36a2ab12: 46 Add a new NFS mount option called "mountport" that may be used 47 to specify the port# for the NFS server's Mount protocol. 48 This permits a NFSv3 mount to be done without running rpcbind(8). 49 50b2f7c53430c3: 51 Kernel TLS is now enabled by default in kernels including KTLS 52 support. KTLS is included in GENERIC kernels for aarch64, 53 amd64, powerpc64, and powerpc64le. 54 55f57efe95cc25: 56 New mididump(1) utility which dumps MIDI 1.0 events in real time. 57 58ddfc6f84f242: 59 Update unicode to 16.0.0 and CLDR to 45.0.0. 60 61b22be3bbb2de: 62 Basic Cloudinit images no longer generate RSA host keys by default for 63 SSH. 64 65000000000000: 66 RSA host keys for SSH are deprecated and will no longer be generated 67 by default in FreeBSD 16. 68 690aabcd75dbc2: 70 EC2 AMIs no longer generate RSA host keys by default for SSH. RSA 71 host key generation can be re-enabled by setting sshd_rsa_enable="YES" 72 in /etc/rc.conf if it is necessary to support very old SSH clients. 73 74a1da7dc1cdad: 75 The SO_SPLICE socket option was added. It allows TCP connections to 76 be spliced together, enabling proxy-like functionality without the 77 need to copy data in and out of user memory. 78 79fc12c191c087: 80 grep(1) no longer follows symbolic links by default for 81 recursive searches. This matches the documented behavior in 82 the manual page. 83 84e962b37bf0ff: 85 When running bhyve(8) guests with a boot ROM, i.e., bhyveload(8) is not 86 used, bhyve now assumes that the boot ROM will enable PCI BAR decoding. 87 This is incompatible with some boot ROMs, particularly outdated builds 88 of edk2-bhyve. To restore the old behavior, add 89 "pci.enable_bars='true'" to your bhyve configuration. 90 91 Note in particular that the uefi-edk2-bhyve package has been renamed 92 to edk2-bhyve. 93 9443caa2e805c2: 95 amd64 bhyve(8)'s "lpc.bootrom" and "lpc.bootvars" options are 96 deprecated. Use the top-level "bootrom" and "bootvars" options 97 instead. 98 99822ca3276345: 100 byacc was updated to 20240109. 101 10221817992b331: 103 ncurses was updated to 6.5. 104 1051687d77197c0: 106 Filesystem manual pages have been moved to section four. 107 Please check ports you are maintaining for crossreferences. 108 1098aac90f18aef: 110 new MAC/do policy and mdo(1) utility which enables a user to 111 become another user without the requirement of setuid root. 112 1137398d1ece5cf: 114 hw.snd.version is removed. 115 116a15f7c96a276,a8089ea5aee5: 117 NVMe over Fabrics controller. The nvmft(4) kernel module adds 118 a new frontend to the CAM target layer which exports ctl(4) 119 LUNs as NVMe namespaces to remote hosts. The nvmfd(8) daemon 120 is responsible for accepting incoming connection requests and 121 handing off connected queue pairs to nvmft(4). 122 123a1eda74167b5,1058c12197ab: 124 NVMe over Fabrics host. New commands added to nvmecontrol(8) 125 to establish connections to remote controllers. Once 126 connections are established they are handed off to the nvmf(4) 127 kernel module which creates nvmeX devices and exports remote 128 namespaces as nda(4) disks. 129 13025723d66369f: 131 As a side-effect of retiring the unit.* code in sound(4), the 132 hw.snd.maxunit loader(8) tunable is also retired. 133 134eeb04a736cb9: 135 date(1) now supports nanoseconds. For example: 136 `date -Ins` prints "2024-04-22T12:20:28,763742224+02:00" and 137 `date +%N` prints "415050400". 138 1396d5ce2bb6344: 140 The default value of the nfs_reserved_port_only rc.conf(5) setting has 141 changed. The FreeBSD NFS server now requires the source port of 142 requests to be in the privileged port range (i.e., <= 1023), which 143 generally requires the client to have elevated privileges on their local 144 system. The previous behavior can be restored by setting 145 nfs_reserved_port_only=NO in rc.conf. 146 147aea973501b19: 148 ktrace(2) will now record detailed information about capability mode 149 violations. The kdump(1) utility has been updated to display such 150 information. 151 152f32a6403d346: 153 One True Awk updated to 2nd Edition. See https://awk.dev for details 154 on the additions. Unicode and CSVs (Comma Separated Values) are now 155 supported. 156 157fe86d923f83f: 158 usbconfig(8) now reads the descriptions of the usb vendor and products 159 from usb.ids when available, similarly to what pciconf(8) does. 160 1614347ef60501f: 162 The powerd(8) utility is now enabled in /etc/rc.conf by default on 163 images for the arm64 Raspberry Pi's (arm64-aarch64-RPI img files). 164 This prevents the CPU clock from running slow all the time. 165 1660b49e504a32d: 167 rc.d/jail now supports the legacy variable jail_${jailname}_zfs_dataset 168 to allow unmaintained jail managers like ezjail to make use of this 169 feature (simply rename jail_${jailname}_zfs_datasets in the ezjail 170 config to jail_${jailname}_zfs_dataset. 171 172e0dfe185cbca: 173 jail(8) now support zfs.dataset to add a list of ZFS datasets to a 174 jail. 175 17661174ad88e33: 177 newsyslog(8) now supports specifying a global compression method directly 178 at the beginning of the newsyslog.conf file, which will make newsyslog(8) 179 to behave like the corresponding option was passed to the newly added 180 '-c' option. For example: 181 182 <compress> none 183 184906748d208d3: 185 newsyslog(8) now accepts a new option, '-c' which overrides all historical 186 compression flags by treating their meaning as "treat the file as compressible" 187 rather than "compress the file with that specific method." 188 189 The following choices are available: 190 * none: Do not compress, regardless of flag. 191 * legacy: Historical behavior (J=bzip2, X=xz, Y=zstd, Z=gzip). 192 * bzip2, xz, zstd, gzip: apply the specified compression method. 193 194 We plan to change the default to 'none' in FreeBSD 15.0. 195 1961a878807006c: 197 This commit added some statistics collection to the NFS-over-TLS 198 code in the NFS server so that sysadmins can moditor usage. 199 The statistics are available via the kern.rpc.tls.* sysctls. 200 2017c5146da1286: 202 Mountd has been modified to use strunvis(3) to decode directory 203 names in exports(5) file(s). This allows special characters, 204 such as blanks, to be embedded in the directory name(s). 205 "vis -M" may be used to encode such directory name(s). 206 207c5359e2af5ab: 208 bhyve(8) has a new network backend, "slirp", which makes use of the 209 libslirp package to provide a userspace network stack. This backend 210 makes it possible to access the guest network from the host without 211 requiring any extra network configuration on the host. 212 213bb830e346bd5: 214 Set the IUTF8 flag by default in tty(4). 215 216 128f63cedc14 and 9e589b093857 added proper UTF-8 backspacing handling 217 in the tty(4) driver, which is enabled by setting the new IUTF8 flag 218 through stty(1). Since the default locale is UTF-8, enable IUTF8 by 219 default. 220 221ff01d71e48d4: 222 dialog(1) has been replaced by bsddialog(1) 223 22441582f28ddf7: 225 FreeBSD 15.0 will not include support for 32-bit platforms. 226 However, 64-bit systems will still be able to run older 32-bit 227 binaries. 228 229 Support for executing 32-bit binaries on 64-bit platforms via 230 COMPAT_FREEBSD32 will remain supported for at least the 231 stable/15 and stable/16 branches. 232 233 Support for compiling individual 32-bit applications via 234 `cc -m32` will also be supported for at least the stable/15 235 branch which includes suitable headers in /usr/include and 236 libraries in /usr/lib32. 237 238 Support for 32-bit platforms in ports for 15.0 and later 239 releases is also deprecated, and these future releases may not 240 include binary packages for 32-bit platforms or support for 241 building 32-bit applications from ports. 242 243 stable/14 and earlier branches will retain existing 32-bit 244 kernel and world support. Ports will retain existing support 245 for building ports and packages for 32-bit systems on stable/14 246 and earlier branches as long as those branches are supported 247 by the ports system. However, all 32-bit platforms are Tier-2 248 or Tier-3 and support for individual ports should be expected 249 to degrade as upstreams deprecate 32-bit platforms. 250 251 With the current support schedule, stable/14 will be EOLed 5 252 years after the release of 14.0. The EOL of stable/14 would 253 mark the end of support for 32-bit platforms including source 254 releases, pre-built packages, and support for building 255 applications from ports. Given an estimated release date of 256 October 2023 for 14.0, support for 32-bit platforms would end 257 in October 2028. 258 259 The project may choose to alter this approach when 15.0 is 260 released by extending some level of 32-bit support for one or 261 more platforms in 15.0 or later. Users should use the 262 stable/14 branch to migrate off of 32-bit platforms. 263
