1Release notes for FreeBSD 14.0. 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 137344856e3a6d and many others: 14 Add support so that nfsd(8), nfsuserd(8), mountd(8), gssd(8) 15 and rpc.tlsservd(8) can be run in an appropriately configured 16 vnet prison. The vnet prison must be on its own file system, 17 have the "allow.nfsd" jail parameter set on it and enforce_statfs 18 cannot be set to "0". Use of UDP and pNFS server configurations 19 are not permitted. (ie. The nfsd command line options "-u", "-p" 20 and "-m" are not supported.) 21 See jail(8), nfsd(8) and mountd(8). 22 232fb4f839f3fc,d89513ed2050,3413ee88c39d,f97a19ecb985,021562c5020d,431d2a81d421: 24 sendmail has been updated to the latest upstream version (8.17.1). 25 264a30d7bb373c,d670a8f7c596,af01b4722577,4e240e55d818: 27 The growfs(7) script can now add a swap partition at the end of 28 the expansion area, and does so by default if there is no existing 29 swap. See growfs(7). 30 3186edb11e7491: 32 llvm-objump is now always installed as objdump. 33 34616f32ea6da7: 35 mta_start_script along with othermta rc.d script has been retired. 36 37a67b925ff3e5: 38 The default mail transport agent is now dma(8) replacing sendmail. 39 4022893e584032: 41 L3 filtering on if_bridge will do surprising things which aren't 42 fail-safe, so net.link.bridge.pfil_member and 43 net.link.bridge.pfil_bridge now default to zero. 44 45f0bc4ed144fc: 46 A new DTrace provider, kinst, is introduced and documented in 47 dtrace_kinst(4). The provider allows kernel instructions to be traced, 48 similar to the FBT (function boundary tracing) provider except that all 49 instructions may be probed instead of logical entry and return 50 instructions. The provider is currently amd64-only. 51 520eea46fb1f83: 53 Removed telnetd. 54 55981ef32230b2,33721eb991d8: 56 These commits make the use of NFSv4.1/4.2 mounts with the "intr" 57 mount option fairly usable, although not 100% correct, so long as 58 the "nolockd" mount option is used as well. See the mount_nfs(8) 59 manual page for more information. 60 61b875d4f5ddcb,0685c73cfe88: 62 The NFSv4.1/4.2 client and server will now generate console messages 63 if sessions are broken, suggesting that users check to ensure 64 that the /etc/hostid strings are unique for all NFSv4.1/4.2 clients. 65 66240afd8c1fcc: 67 makefs(8) has ZFS support; it can create a ZFS pool, backed by a 68 single disk vdev, containing one or more datasets populated from 69 the staging directory. 70 7178ee8d1c4cda,f4f56ff43dbd: 72 The in-tree qat(4) driver has been replaced with Intel's QAT driver. 73 The new version provides additional interfaces to the chipset's 74 cryptographic and compression offload functionality. 75 76 This will have no visible change for most users; however, the new 77 driver does not support Atom C2000 chipsets. To preserve support for 78 those chipsets, the old driver has been renamed to qat_c2xxx and kept 79 in the tree. Users of qat(4) on C2000 hardware will thus need to 80 ensure that qat_c2xxx(4) is loaded instead of qat(4). 81 82da5b7e90e740,5a8fceb3bd9f,7b0a665d72c0,13ec1e3155c7,318d0db5fe8a,1ae2c59bcf21: 83 Boottrace is a new kernel-userspace interface for capturing trace 84 events during system boot and shutdown. Event annotations are 85 present in: 86 87 - The boot and shutdown paths in the kernel 88 - Some key system utilities (init(8), shutdown(8), reboot(8)) 89 - rc(8) scripts (via boottrace(8)) 90 91 In contrast to other existing boot-time tracing facilities like TSLOG, 92 Boottrace focuses on the ease of use and is aimed primarily at system 93 administrators. 94 95 It is available in the default GENERIC kernel and can be enabled by 96 toggling a single sysctl(8) variable. 97 98 See boottrace(4) for more details. 99 10005a1d0f5d7ac: 101 Kernel TLS offload now supports receive-side offload of TLS 1.3. 102 10319dc64451179: 104 if_stf now supports 6rd (RFC5969). 105 106c1d255d3ffdb, 3968b47cd974, bd452dcbede6: 107 Add WiFi 6 support to wpa. 108 109ba48d52ca6c8,4ac3d08a9693,2533eca1c2b9: 110 The default bell tone is now 800Hz. It may be set with kbdcontrol 111 again. There's devd integration for people wishing to use their sound 112 cards for the beep. 113 11492b3e07229ba: 115 net.inet.tcp.nolocaltimewait enabled by default. It prevents 116 creation of timewait entries for TCP connections that were 117 terminated locally. 118 119d410b585b6f0: 120 sh(1) is now the default shell for the root user. 121 122396851c20aeb: 123 libncursesw has been split into libtinfow and libncursesw, linker 124 scripts should make it transparent for consumers. pkg-config files 125 are also now installed to ease ports detecting the ncurses setup from 126 base. 127 128a422084abbda: 129 LLVM's MemorySanitizer can now be used in amd64 kernels. See the 130 kmsan(9) manual page for more information. 131 13238da497a4dfc: 133 LLVM's AddressSanitizer can now be used in amd64 kernels. See the 134 kasan(9) manual page for more information. 135 136f39dd6a97844,23f24377b1a9,628bd30ab5a4: 137 One True Awk has been updated to the latest from upstream 138 (20210727). All the FreeBSD patches, but one, have now been 139 either up streamed or discarded. Notable changes include: 140 o Locale is no longer used for ranges 141 o Various bugs fixed 142 o Better compatibility with gawk and mawk 143 144 The one FreeBSD change, likely to be removed in FreeBSD 14, is that 145 we still allow hex numbers, prefixed with 0x, to be parsed and 146 interpreted as hex numbers while all other awks (including one 147 true awk now) interpret them as 0 in line with awk's historic 148 behavior. 149 150 A second change, less likely to be noticed, is the historic wart 151 if -Ft meaning to use hard tab characters as the field separator 152 is deprecated and will likely be removed in FreeBSD 14. 153 154ee29e6f31111: 155 Commit ee29e6f31111 added a new sysctl called vfs.nfsd.srvmaxio 156 that can be used to increase the maximum I/O size for the NFS 157 server to any power of 2 up to 1Mbyte while the nfsd(8) is not running. 158 The FreeBSD NFS client can now be set to use a 1Mbyte I/O size 159 via the vfs.maxbcachebuf tunable and the Linux NFS client 160 can also do 1Mbyte I/O. 161 kern.ipc.maxsockbuf will need to be increased. A console 162 message will suggest a setting for it. 163 164d575e81fbcfa: 165 gconcat(8) has added support for appending devices to the device 166 not present at creation time. 167 16876681661be28: 169 Remove support for asymmetric cryptographic operations from 170 the kernel open cryptographic framework (OCF). 171 172a145cf3f73c7: 173 The NFSv4 client now uses the highest minor version of NFSv4 174 supported by the NFSv4 server by default instead of minor version 0, 175 for NFSv4 mounts. 176 The "minorversion" mount option may be used to override this default. 177
