Systems which installed with pkgbase prior to - 15.0-RC1 (if running releng/15.0) or November 15th (if running from - stable/main snapshots) will need to remove the definition of the - FreeBSD-base repository from /usr/local/etc/pkg/repos/ and replace - it with a single line "FreeBSD-base: { enabled: yes }". - -5000d023a446, 03da141d59ae: - Add a "-f" option to "kadmin -l dump" which can be used to - dump the Heimdal KDC database in a format that can be loaded - into the MIT KDC. - See https://wiki.freebsd.org/Kerberos/Heimdal2MIT_KDC_Migration - for how to use "-f" to transfer/convert the KDC database. - -9cab9fde5eda: - virtual_oss is imported to base. The audio/virtual_oss port will stop - being built from FreeBSD 15.0 onwards. - - Regarding user-facing changes, the only practical difference is the - installation process. Everything is provided by the base system, except - for the following optional components, which can be installed from - ports: - - * sndio backend support: audio/virtual_oss_sndio - * bluetooth backend support: audio/virtual_oss_bluetooth - * virtual_equalizer(8): audio/virtual_oss_equalizer - - Apart from that, virtual_oss should work as expected.

The GSSAPI - libraries are now always built unless WITHOUT_KERBEROS is set. - -c43cad871720: - jemalloc 5.3.0 has landed. See contrib/jemalloc/ChangeLog - for the long list of changes. - -cce64f2e6851: - Add support for the NFSv4.2 Clone operation, which uses - block cloning to "copy on write" files on an NFS server. - This only works for exported ZFS file systems that have - block cloning enabled, at this time. - -37b2cb5ecb0f: - Add support to VOP_COPY_FILE_RANGE() for block cloning. - At this time, ZFS is the only local file system that supports - this and only if block cloning is enabled. NFSv4.2 also supports it. - See pathconf(2) and copy_file_range(2) for more information. - -2ec2ba7e232d, df58e8b1506f (openzfs 2957eabbe), f61844833ee8, b1b607bd200f, - ee95e4d02dbd: - Add Solaris style extended attributes (called named attributes - in NFSv4). At this time, only ZFS when the ZFS property called - xattr=dir and NFSv4 support them. The attributes are presented - in a directory as regular files. See named_attribute(7) for - more information. - -ef2a572bf6: - Inline IPSEC offload infrastructure and driver support for mlx5(4) - Nvidia ConnectX-6+ network cards were added. - -68ba38dad3: - amd64: handling of the %fsbase/%gsbase registers and tls base - were reworked, making it more useful for apps that directly - manipulate CPU context. - -78aaab9f1cf: - rtld: added support for -z initfirst - -e36f069ecb4, c069ca085b: - Reliability of UFS on volumes with more than 2G of inodes is - significantly improved. The underlying issue was the invalid - interpretation of the 32bit inode number as signed, which got - sign-extended into ino_t. - -d390633cf8c: - On modern amd64 machines (which have the LA57 CPU feature), - FreeBSD is able to utilize more than 4TB of RAM. - -2bd157bc732a: - The readdir_r(3) function is deprecated and may be removed in future - releases. Using it in a program will result in compile-time and - link-time warnings. - -9ba51cce8bbd: - bsnmpd(1) no longer supports legacy UDP transport. Users, that have - not updated their /etc/snmpd.config since 12.0-RELEASE or older will - need to merge in the new configuration. In particular, the transport - definition shall be changed from begemotSnmpdPortStatus OID to - begemotSnmpdTransInetStatus. - -1349a733cf28: - Add a driver supporting a new storage controller interface, - Universal Flash Storage Host Controller Interface, supporting - version 4.1 and earlier, via ufshci(4). - -f1f230439fa4: - FreeBSD now implements the inotify(2) family of system calls. - -50e733f19b37, 171f66b0c2ca: - These commits helped improve utilization of NFSv4.1/4.2 - delegations. The changes are only used when the NFSv4 - mount uses the "nocto" mount option and requires an - up-to-date NFSv4.1/4.2 server with delegations enabled. - For example: For a FreeBSD kernel build with both src - and obj NFSv4 mounted, the total RPC count dropped from - 5461286 to 945643, with a 20% drop in elapsed time. - -c3fc0db3bc50 - The default value of the sysctl variable - net.inet.tcp.nolocaltimewait has changed from 1 to 0. This means - that FreeBSD does not skip the TIME_WAIT state anymore for - endpoints for which the remote address is local. The new sysctl - variable net.inet.tcp.msl_local can be used to control the time - these endpoints stay in the TIME_WAIT state. The sysctl variable - net.inet.tcp.nolocaltimewait is deprecated and intended to be - removed in FreeBSD 16. - -cd240957d7ba - Making a connection to INADDR_ANY (i.e., using INADDR_ANY as an alias - for localhost) is now disabled by default. This functionality can be - re-enabled by setting the net.inet.ip.connect_inaddr_wild sysctl to 1. - -b61850c4e6f6 - The bridge(4) sysctl net.link.bridge.member_ifaddrs now defaults to 0, - meaning that interfaces added to a bridge may not have IP addresses - assigned. Refer to bridge(4) for more information. - -44e5a0150835, 9a37f1024ceb: - A new utility sndctl(8) has been added to concentrate the various - interfaces for viewing and manipulating audio device settings (sysctls, - /dev/sndstat), into a single utility with a similar control-driven - interface to that of mixer(8). - -93a94ce731a8: - ps(1)'s options '-a' and '-A', when combined with any other one - affecting the selection of processes except for '-X' and '-x', would - have no effect, in contradiction with the rule that one process is - listed as soon as any of the specified options selects it (inclusive - OR), which is both mandated by POSIX and arguably a natural expectation. - This bug has been fixed. - - As a practical consequence, specifying '-a'/'-A' now causes all - processes to be listed regardless of other selection options (except for - '-X' and '-x', which still apply). In particular, to list only - processes from specific jails, one must not use '-a' with '-J'. Option - '-J', contrary to its apparent initial intent, never worked as a filter - in practice (except by accident with '-a' due to the bug), but instead - as any other selection options (e.g., '-U', '-p', '-G', etc.) subject to - the "inclusive OR" rule. - -995b690d1398: - ps(1)'s '-U' option has been changed to select processes by their real - user IDs instead of their effective one, in accordance with POSIX and - the use case of wanting to list processes launched by some user, which - is expected to be more frequent than listing processes having the rights - of some user. This only affects the selection of processes whose real - and effective user IDs differ. After this change, ps(1)'s '-U' flag - behaves differently then in other BSDs but identically to that of - Linux's procps and illumos. - -1aabbb25c9f9: - ps(1)'s default list of processes now comes from matching its effective - user ID instead of its real user ID with the effective user ID of all - processes, in accordance with POSIX. As ps(1) itself is not installed - setuid, this only affects processes having different real and effective - user IDs that launch ps(1) processes. - -f0600c41e754-de701f9bdbe0, bc201841d139: - mac_do(4) is now considered production-ready and its functionality has - been considerably extended at the price of breaking credentials - transition rules' backwards compatibility. All that could be specified - with old rules can also be with new rules. Migrating old rules is just - a matter of adding "uid=" in front of the target part, substituting - commas (",") with semi-colons (";") and colons (":") with greater-than - signs (">"). Please consult the mac_do(4) manual page for the new rules - grammar. - -02d4eeabfd73: - hw.snd.maxautovchans has been retired. The commit introduced a - hw.snd.vchans_enable sysctl, which along with - dev.pcm.X.{play|rec}.vchans, from now on work as tunables to only - enable/disable vchans, as opposed to setting their number and/or - (de-)allocating vchans. Since these sysctls do not trigger any - (de-)allocations anymore, their effect is instantaneous, whereas before - we could have frozen the machine (when trying to allocate new vchans) - when setting dev.pcm.X.{play|rec}.vchans to a very large value. - -7e7f88001d7d: - The definition of pf's struct pfr_tstats and struct pfr_astats has - changed, breaking ABI compatibility for 32-bit powerpc (including - powerpcspe) and armv7. Users of these platforms should ensure kernel - and userspace are updated together. - -5dc99e9bb985, 08e638c089a, 4009a98fe80: - The net.inet.{tcp,udp,raw}.bind_all_fibs tunables have been added. - They modify socket behavior such that packets not originating from the - same FIB as the socket are ignored. TCP and UDP sockets belonging to - different FIBs may also be bound to the same address. The default - behavior is unmodified. - -f87bb5967670, e51036fbf3f8: - Support for vinum volumes has been removed. - -8ae6247aa966, cf0ede720391d, 205659c43d87bd, 1ccbdf561f417, 4db1b113b151: - The layout of NFS file handles for the tarfs, tmpfs, cd9660, and ext2fs - file systems has changed. An NFS server that exports any of these file - systems will need its clients to unmount and remount the exports. - -1111a44301da: - Defer the January 19, 2038 date limit in UFS1 filesystems to - February 7, 2106. This affects only UFS1 format filesystems. - See the commit message for details. - -07cd69e272da: - Add a new -a command line option to mountd(8). - If this command line option is specified, when - a line in exports(5) has the -alldirs export option, - the directory must be a server file system mount point. - -0e8a36a2ab12: - Add a new NFS mount option called "mountport" that may be used - to specify the port# for the NFS server's Mount protocol. - This permits a NFSv3 mount to be done without running rpcbind(8). - -b2f7c53430c3: - Kernel TLS is now enabled by default in kernels including KTLS - support. KTLS is included in GENERIC kernels for aarch64, - amd64, powerpc64, and powerpc64le. - -f57efe95cc25: - New mididump(1) utility which dumps MIDI 1.0 events in real time. - -ddfc6f84f242: - Update unicode to 16.0.0 and CLDR to 45.0.0. - -b22be3bbb2de: - Basic Cloudinit images no longer generate RSA host keys by default for - SSH. - -000000000000: - RSA host keys for SSH are deprecated and will no longer be generated - by default in FreeBSD 16. - -0aabcd75dbc2: - EC2 AMIs no longer generate RSA host keys by default for SSH. RSA - host key generation can be re-enabled by setting sshd_rsa_enable="YES" - in /etc/rc.conf if it is necessary to support very old SSH clients. - -a1da7dc1cdad: - The SO_SPLICE socket option was added. It allows TCP connections to - be spliced together, enabling proxy-like functionality without the - need to copy data in and out of user memory. - -fc12c191c087: - grep(1) no longer follows symbolic links by default for - recursive searches. This matches the documented behavior in - the manual page. - -e962b37bf0ff: - When running bhyve(8) guests with a boot ROM, i.e., bhyveload(8) is not - used, bhyve now assumes that the boot ROM will enable PCI BAR decoding. - This is incompatible with some boot ROMs, particularly outdated builds - of edk2-bhyve. To restore the old behavior, add - "pci.enable_bars='true'" to your bhyve configuration. - - Note in particular that the uefi-edk2-bhyve package has been renamed - to edk2-bhyve. - -43caa2e805c2: - amd64 bhyve(8)'s "lpc.bootrom" and "lpc.bootvars" options are - deprecated. Use the top-level "bootrom" and "bootvars" options - instead. - -822ca3276345: - byacc was updated to 20240109. - -21817992b331: - ncurses was updated to 6.5. - -1687d77197c0: - Filesystem manual pages have been moved to section four. - Please check ports you are maintaining for crossreferences. - -8aac90f18aef: - new MAC/do policy and mdo(1) utility which enables a user to - become another user without the requirement of setuid root. - -7398d1ece5cf: - hw.snd.version is removed. - -a15f7c96a276,66b5296f1b29: - NVMe over Fabrics controller. The nvmft(4) kernel module adds - a new frontend to the CAM target layer which exports ctl(4) - LUNs as NVMe namespaces to remote hosts. The ctld(8) daemon - now supports NVMe controllers in addition to iSCSI targets and - is responsible for accepting incoming connection requests and - handing off connected queue pairs to nvmft(4). - -a1eda74167b5,1058c12197ab: - NVMe over Fabrics host. New commands added to nvmecontrol(8) - to establish connections to remote controllers. Once - connections are established they are handed off to the nvmf(4) - kernel module which creates nvmeX devices and exports remote - namespaces as nda(4) disks. - -25723d66369f: - As a side-effect of retiring the unit.* code in sound(4), the - hw.snd.maxunit loader(8) tunable is also retired. - -eeb04a736cb9: - date(1) now supports nanoseconds. For example: - `date -Ins` prints "2024-04-22T12:20:28,763742224+02:00" and - `date +%N` prints "415050400". - -6d5ce2bb6344: - The default value of the nfs_reserved_port_only rc.conf(5) setting has - changed. The FreeBSD NFS server now requires the source port of - requests to be in the privileged port range (i.e., <= 1023), which - generally requires the client to have elevated privileges on their local - system. The previous behavior can be restored by setting - nfs_reserved_port_only=NO in rc.conf. - -aea973501b19: - ktrace(2) will now record detailed information about capability mode - violations. The kdump(1) utility has been updated to display such - information. - -f32a6403d346: - One True Awk updated to 2nd Edition. See https://awk.dev for details - on the additions. Unicode and CSVs (Comma Separated Values) are now - supported. - -fe86d923f83f: - usbconfig(8) now reads the descriptions of the usb vendor and products - from usb.ids when available, similarly to what pciconf(8) does. - -4347ef60501f: - The powerd(8) utility is now enabled in /etc/rc.conf by default on - images for the arm64 Raspberry Pi's (arm64-aarch64-RPI img files). - This prevents the CPU clock from running slow all the time. - -0b49e504a32d: - rc.d/jail now supports the legacy variable jail_${jailname}_zfs_dataset - to allow unmaintained jail managers like ezjail to make use of this - feature (simply rename jail_${jailname}_zfs_datasets in the ezjail - config to jail_${jailname}_zfs_dataset. - -e0dfe185cbca: - jail(8) now support zfs.dataset to add a list of ZFS datasets to a - jail. - -61174ad88e33: - newsyslog(8) now supports specifying a global compression method directly - at the beginning of the newsyslog.conf file, which will make newsyslog(8) - to behave like the corresponding option was passed to the newly added - '-c' option. For example: - - <compress> none - -906748d208d3: - newsyslog(8) now accepts a new option, '-c' which overrides all historical - compression flags by treating their meaning as "treat the file as compressible" - rather than "compress the file with that specific method." - - The following choices are available: - * none: Do not compress, regardless of flag. - * legacy: Historical behavior (J=bzip2, X=xz, Y=zstd, Z=gzip). - * bzip2, xz, zstd, gzip: apply the specified compression method. - - We plan to change the default to 'none' in FreeBSD 15.0. - -1a878807006c: - This commit added some statistics collection to the NFS-over-TLS - code in the NFS server so that sysadmins can moditor usage. - The statistics are available via the kern.rpc.tls.* sysctls. - -7c5146da1286: - Mountd has been modified to use strunvis(3) to decode directory - names in exports(5) file(s). This allows special characters, - such as blanks, to be embedded in the directory name(s). - "vis -M" may be used to encode such directory name(s). - -c5359e2af5ab: - bhyve(8) has a new network backend, "slirp", which makes use of the - libslirp package to provide a userspace network stack. This backend - makes it possible to access the guest network from the host without - requiring any extra network configuration on the host. - -bb830e346bd5: - Set the IUTF8 flag by default in tty(4). - - 128f63cedc14 and 9e589b093857 added proper UTF-8 backspacing handling - in the tty(4) driver, which is enabled by setting the new IUTF8 flag - through stty(1). Since the default locale is UTF-8, enable IUTF8 by - default. - -ff01d71e48d4: - dialog(1) has been replaced by bsddialog(1) - -41582f28ddf7: - FreeBSD 15.0 will not include support for 32-bit platforms. - However, 64-bit systems will still be able to run older 32-bit - binaries. - - Support for executing 32-bit binaries on 64-bit platforms via - COMPAT_FREEBSD32 will remain supported for at least the - stable/15 and stable/16 branches. - - Support for compiling individual 32-bit applications via - `cc -m32` will also be supported for at least the stable/15 - branch which includes suitable headers in /usr/include and - libraries in /usr/lib32. - - Support for 32-bit platforms in ports for 15.0 and later - releases is also deprecated, and these future releases may not - include binary packages for 32-bit platforms or support for - building 32-bit applications from ports. - - stable/14 and earlier branches will retain existing 32-bit - kernel and world support. Ports will retain existing support - for building ports and packages for 32-bit systems on stable/14 - and earlier branches as long as those branches are supported - by the ports system. However, all 32-bit platforms are Tier-2 - or Tier-3 and support for individual ports should be expected - to degrade as upstreams deprecate 32-bit platforms. - - With the current support schedule, stable/14 will be EOLed 5 - years after the release of 14.0. The EOL of stable/14 would - mark the end of support for 32-bit platforms including source - releases, pre-built packages, and support for building - applications from ports. Given an estimated release date of - October 2023 for 14.0, support for 32-bit platforms would end - in October 2028. - - The project may choose to alter this approach when 15.0 is - released by extending some level of 32-bit support for one or - more platforms in 15.0 or later. Users should use the - stable/14 branch to migrate off of 32-bit platforms.
