Release notes for FreeBSD 14.0. This file describes new user-visible features, changes and updates relevant to users of binary FreeBSD releases. Each entry should describe the change in no more than several sentences and should reference manual pages where an interested user can find more information. Entries should wrap after 80 columns. Each entry should begin with one or more commit IDs on one line, specified as a comma separated list and/or range, followed by a colon and a newline. Entries should be separated by a newline. Changes to this file should not be MFCed. 22893e584032: L3 filtering on if_bridge will do surprising things which aren't fail-safe, so net.link.bridge.pfil_member and net.link.bridge.pfil_bridge now default to zero. f0bc4ed144fc: A new DTrace provider, kinst, is introduced and documented in dtrace_kinst(4). The provider allows kernel instructions to be traced, similar to the FBT (function boundary tracing) provider except that all instructions may be probed instead of logical entry and return instructions. The provider is currently amd64-only. 0eea46fb1f83: Removed telnetd. 981ef32230b2,33721eb991d8: These commits make the use of NFSv4.1/4.2 mounts with the "intr" mount option fairly usable, although not 100% correct, so long as the "nolockd" mount option is used as well. See the mount_nfs(8) manual page for more information. b875d4f5ddcb,0685c73cfe88: The NFSv4.1/4.2 client and server will now generate console messages if sessions are broken, suggesting that users check to ensure that the /etc/hostid strings are unique for all NFSv4.1/4.2 clients. 240afd8c1fcc: makefs(8) has ZFS support; it can create a ZFS pool, backed by a single disk vdev, containing one or more datasets populated from the staging directory. 78ee8d1c4cda,f4f56ff43dbd: The in-tree qat(4) driver has been replaced with Intel's QAT driver. The new version provides additional interfaces to the chipset's cryptographic and compression offload functionality. This will have no visible change for most users; however, the new driver does not support Atom C2000 chipsets. To preserve support for those chipsets, the old driver has been renamed to qat_c2xxx and kept in the tree. Users of qat(4) on C2000 hardware will thus need to ensure that qat_c2xxx(4) is loaded instead of qat(4). da5b7e90e740,5a8fceb3bd9f,7b0a665d72c0,13ec1e3155c7,318d0db5fe8a,1ae2c59bcf21: Boottrace is a new kernel-userspace interface for capturing trace events during system boot and shutdown. Event annotations are present in: - The boot and shutdown paths in the kernel - Some key system utilities (init(8), shutdown(8), reboot(8)) - rc(8) scripts (via boottrace(8)) In contrast to other existing boot-time tracing facilities like TSLOG, Boottrace focuses on the ease of use and is aimed primarily at system administrators. It is available in the default GENERIC kernel and can be enabled by toggling a single sysctl(8) variable. See boottrace(4) for more details. 05a1d0f5d7ac: Kernel TLS offload now supports receive-side offload of TLS 1.3. 19dc64451179: if_stf now supports 6rd (RFC5969). c1d255d3ffdb, 3968b47cd974, bd452dcbede6: Add WiFi 6 support to wpa. ba48d52ca6c8,4ac3d08a9693,2533eca1c2b9: The default bell tone is now 800Hz. It may be set with kbdcontrol again. There's devd integration for people wishing to use their sound cards for the beep. 92b3e07229ba: net.inet.tcp.nolocaltimewait enabled by default. It prevents creation of timewait entries for TCP connections that were terminated locally. d410b585b6f0: sh(1) is now the default shell for the root user. 396851c20aeb: libncursesw has been split into libtinfow and libncursesw, linker scripts should make it transparent for consumers. pkg-config files are also now installed to ease ports detecting the ncurses setup from base. a422084abbda: LLVM's MemorySanitizer can now be used in amd64 kernels. See the kmsan(9) manual page for more information. 38da497a4dfc: LLVM's AddressSanitizer can now be used in amd64 kernels. See the kasan(9) manual page for more information. f39dd6a97844,23f24377b1a9,628bd30ab5a4: One True Awk has been updated to the latest from upstream (20210727). All the FreeBSD patches, but one, have now been either up streamed or discarded. Notable changes include: o Locale is no longer used for ranges o Various bugs fixed o Better compatibility with gawk and mawk The one FreeBSD change, likely to be removed in FreeBSD 14, is that we still allow hex numbers, prefixed with 0x, to be parsed and interpreted as hex numbers while all other awks (including one true awk now) interpret them as 0 in line with awk's historic behavior. A second change, less likely to be noticed, is the historic wart if -Ft meaning to use hard tab characters as the field separator is deprecated and will likely be removed in FreeBSD 14. ee29e6f31111: Commit ee29e6f31111 added a new sysctl called vfs.nfsd.srvmaxio that can be used to increase the maximum I/O size for the NFS server to any power of 2 up to 1Mbyte while the nfsd(8) is not running. The FreeBSD NFS client can now be set to use a 1Mbyte I/O size via the vfs.maxbcachebuf tunable and the Linux NFS client can also do 1Mbyte I/O. kern.ipc.maxsockbuf will need to be increased. A console message will suggest a setting for it. d575e81fbcfa: gconcat(8) has added support for appending devices to the device not present at creation time. 76681661be28: Remove support for asymmetric cryptographic operations from the kernel open cryptographic framework (OCF). a145cf3f73c7: The NFSv4 client now uses the highest minor version of NFSv4 supported by the NFSv4 server by default instead of minor version 0, for NFSv4 mounts. The "minorversion" mount option may be used to override this default.
