1Release notes for FreeBSD 16.0. 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 136563dcb6b1f5: 14 It is now possible to use connectat(2) to connect to a unix(4) socket 15 directly, i.e., without having to specify a name in the sockaddr. 16 1772e57bc26417, 3dfbbe8586bb, d8e8f9251975: 18 These patches provide improvements for the pNFS server 19 configuration. New optional features include: 20 - Support for striped Flexible File Layouts (RFC8435). 21 - Support for pre-creation of files, allowing the 22 Open/Create to be done without communicating with 23 any DSs, so long as the cache of pre-created files 24 is not depleted. 25 26b92b9da33006, 13d3bd165e22: 27 This patch allows vfs.nfsd.srvmaxio to be set to 28 a value as high as 4Mbytes. It is usually set 29 via the nfs_server_maxio variable in /etc/rc.conf. 30 314c486fe40267: 32 The multicast routing modules, ip_mroute and ip6_mroute, are now FIB-aware. 33 That is, there is a multicast routing table per FIB, rather than a global 34 table. One can run a multicast routing daemon within each FIB; the FIB of 35 the routing socket determines the corresponding multicast routing table. 36 375c2186b99254,628d7a3270b6: 38 When the sector size for an NVMe namespace changes, nda(4) now 39 reports this as a media change rather than a disk resize 40 event. nda(4) also no longer reports a disk resize event in 41 some cases when the namespace's size had not changed. nda(4) 42 also reprobes NVMe namespaces each time they are opened to 43 check for a new sector size or namespace size. 44 457a323f873662: 46 Remove the le(4) driver. This driver supported older 10Mbps 47 and 100Mbps Ethernet adapters. True hardware devices have not 48 been used in FreeBSD systems in many years, but the driver was 49 previously retained for use with MIPS QEMU virtual machines. 50 51e51ef8ae490f: 52 Add initial support for instruction-based sampling (IBS) 53 performance counters on AMD processors to hwpmc(4). 54 55d69fc3a9dc71: 56 The EFI boot loader now tries all ZFS pools found during 57 probing when looking for a boot pool. Previously it would try 58 only the first pool found. 59 604d5c434ed16e: 61 Use the BSD-licensed implementation of diff3 instead of GNU diff3 62 by default. 63 647f54c65abc67: 65 Update the smartpqi(4) driver to vendor version 14.4690.0.2008 66 - 15.2.0.2008. This includes support for new controllers and 67 renaming Microsemi to Microchip. 68 69350c1232a57a: 70 nvmecontrol(8)'s telemetry-log now works reliably. 71 72d14e018024bb,b125c4d13095,1322760fd127,0730a05cd383: 73 Permit both SCHED_ULE and SCHED_4BSD to be compiled into the 74 same kernel. The scheduler can be selected at boot time by 75 setting the kern.sched_name tunable to the scheduler name 76 ("4BSD" or "ULE"). The default scheduler is ULE. This is 77 currently enabled in amd64 kernels by default. 78 7990a7728cd890: 80 Update nuageinit to request configuration on all network 81 interfaces. nuageinit will now issue DHCP requests on all 82 network interfaces and request configuration data from the 83 first interface which successfully obtains a lease. 84 8592ba9b2fe589: 86 Add RoCE support for Broadcom BCM576xx controllers. 87 88fb4b0c911951: 89 Add a facility to witness(4) to provide more detailed information 90 about lock order reversals detailing when initial lock orders were 91 established. 92 9365f5dd42f11c: 94 sh(1) add -l option which makes sh act as a login shell and read the profile. 95 96beab8b1ddf86: 97 bintrans(1) now supports the RFC2047 variant of quoted print 98 999dc96d8bc3f2: 100 libusb(3) hotplug event are now really hotplugged using either 101 nlsysevent or devd(9) if available. 102 103d64db8892f85: 104 sh(1) is the default shell in the release media. 105 10668ad2b0d7af2: 107 ncurses has been updated to 6.6 108 10952d19df19ed6: 110 nvi(1) has been update to 2.2.2 111 1124d5c434ed16e, 2cfca8e710f2: 113 diff3(1) has replaced GNU diff3 and is now fully compatible. 114 115625dc44832cd: 116 tr(1) is now UTF-8 compliant. 117 11862fba0054d9e: 119 ee(1) is now UTF-8 compliant. 120 1215df6aca10906: 122 ed(1) is now UTF-8 compliant. 123 12428ff4d35f8b9: 125 Update libedit to 2026-04-03. 126 127b42e852e89cb: 128 Add a new pkg-serve(8) to serve packages over TCP via inetd. 129 1308b9775912cbc, 53b4ae3bf0f7: 131 Add support for an NFSv4 root file system. 132 Note that NFSv3 is still used for bootstrapping. See 133 "Diskless Operation with PXE" under "Advanced Networking" in the 134 FreeBSD Handbook. To configure an NFSv4 root fs, you will need 135 a line in /boot/loader.conf like boot.nfsroot.options="nfsv4" and 136 either a line in /etc/sysctl.conf like vfs.nfs.enable_uidtostring=1 137 or an additional line in /boot/loader.conf like 138 boot.nfsroot.user_domain="<user-domain>", 139 if you are running nfsuserd(8). 140 141ab9257599a5: 142 The src.conf(5) options WITHOUT_BZIP2 and WITHOUT_BZIP2_SUPPORT 143 have been removed. 144 145af099eaa5ec: 146 Users belonging to the new vmm group can now create bhyve VMs. See the 147 vmm(4) man page for details. 148 149c71354030a2: 150 Users wishing to use bhyve PCI passthrough in jails must create the 151 jail with the allow.vmm_ppt option configured. 152 1534d707825bf62: 154 The pdwait(2) system call was added. It provides wait(2)-like 155 functionality for a process descriptor (see procdesc(4)). 156 1575c2ee618d5ec: 158 The pdrfork(2) system call was added. It behaves like rfork(2) but 159 additionally returns a process descriptor (see procdesc(4)). 160 16141ccf82b29f3, 591c7a08bf8a: 162 On arm64, memcpy(3), memmove(3) and memset(3) are now implemented using 163 the MOPS (Memory Operations) feature instructions when they are 164 implemented by the system. 165 1663f0aea09689f: 167 posix_spawnattr_getexecfd_np(3) and posix_spawnattr_setexecfd_np(3) 168 functions were added to libc. The latter causes posix_spawn(3) to 169 call fexecve(2) on the specified file descriptor rather than executing 170 the file at the provided path. 171 172fb4b0c911951: 173 witness(4) now prints additional information to the system console when 174 a lock order reversal is detected, making debugging such issues easier. 175 1761322760fd127: 177 It is now possible to compile both the 4BSD and ULE schedulers into the 178 same kernel. The scheduler is selectable at boot-time using a tunable. 179 See the SCHEDULERS section of the tuning(7) man page for details. 180 181627e126dbb07: 182 The default value of the net.inet6.ip6.connect_in6addr_wild has changed 183 to 0. This means that connecting to the all-zeroes IPv6 address no longer 184 implicitly results in a loopback connection. 185 186afa70a8496e9: 187 The pthread_tryjoin_np(3) function was added to libthr(3). It provides 188 the same functionality as pthread_join(3) but returns instead of 189 blocking if the target thread has not yet exited. 190 191ecc039be7fdd: 192 NanoBSD images can now be built as a non-root user. 193 1947f54c65abc67: 195 Update smartpqi(4) to vendor version 14.4690.0.2008 - 15.2.0.2008 196 for the SmartArray storage controllers. This adds support for new 197 controllers, adds code that utilizes the new BIG_IOCTL_Command_struct 198 and allows the I/O buffer size for a single passthrough ioctl to be 199 stored as a 32 bit integer instead of the original 16 bit integer. 200 201b0d997095022: 202 The pf firewall now supports passing IPv6 packets to divert(4) 203 sockets via divert-to actions. 204 2050fa7b3bee72e, c71f18998e0b, 4162a419a475, f5a77dc8f8df: 206 LinuxKPI based wireless drivers, especially iwlwifi(4) are now 207 supported on RISC-V. 208 2098254b0dec02b3, bd55cbb50c588: 210 The mac(4) framework has been extended to support jail operations, 211 allowing a policy to constrain jail creation, modification, removal, and 212 attachment. Jails have additionally been made a first-class mac(4) 213 object, and a mac.label jail(8) property has been added to facilitate 214 administration of their labels. 215 216c558eca47970: 217 The smartpqi(4) driver was updated to vendor version 4660.0.2002 218 for the SmartArry storage controllers. 219 220493d26c58e73: 221 The aq(4) driver was added, imported from the vendor repository. 222 This provides support for Aquantia / Marvell PCIe 1/2.5/5/10 Gigabit 223 Ethernet adapters (AQC107, AQC108, AQC109, AQC111, AQC112). 224 2251a7151f79664: 226 A new CAM provider was added to dtrace. This enables tracing of I/O 227 requests through the CAM layer without relying on fragile function 228 boundary tracing. See dtrace_cam(4) for details. 229 230b8c99e7d912f: 231 The tdestroy(3) function was added to libc. The tdestroy() function 232 destroys a whole search tree, freeing all allocated nodes. 233 2344bf8ce037dc8: 235 The rge(4) driver was added, ported from OpenBSD. This provides 236 support for RealTek RTL8125, RTL8126 and RTL8127 PCIe Ethernet 237 controllers. 238 239cbc6f7e941e4: 240 bhyve(8)'s VNC device can now listen on a unix(4) socket for VNC client 241 connections. 242 24339ee24182b92: 244 An rc(8) service can now be started as a specific user for auditing 245 purposes by setting the <service>_audit_user rc.conf(5) variable. 246 247dcb0790bad43: 248 A setaudit(8) utility was added to the base system. This provides a 249 simple command-line wrapper for the setaudit(2) and setaudit_addr(2) 250 system calls. 251 2528e3fd450cc53, 949cff4dceff, 0e724de9ed6f, 9f49f436a9ec, e35191ccf3b3: 253 Add support for an extension to NFSv4.2 (RFCnnnn) that 254 supports handling of POSIX draft ACLs via getfacl(1)/setfacl(1). 255 256dbac191956f9, fe21dbf70aa8: 257 Support for the kcmp(2) system call and fcntl(F_DUPFD_QUERY) for Linux 258 binaries. 259 260a86dc94b84d1: 261 tzdata2025c was imported. 262 263a98e5d785001: 264 Add strdupa(3) and strndupa(3) macros for compatability with glibc. 265 266e967a2a03677: 267 divert socket compat removal, consumers must use PF_DIVERT instead of 268 PF_INET. 269 2704453ec5b8716b, 2a3b1641756a: 271 The reboot(8) and halt(8) commands now perform a graceful shutdown similar 272 to the shutdown(8) command including invoking rc.d scripts to shutdown 273 services. The fastboot(8) and fasthalt(8) commands still perform a "fast" 274 reboot or shutdown. 275 276d9788eabffa4: 277 ipfilter cannot be used in a jail by default. 278 2790ff0c19e7f70: 280 ipfs(8) is no longer built by default. 281 282575efcfff22f: 283 sendfile(2)'s SF_SYNC flag was removed. 284 285057dae35ffc6, 51a01f3debff, ca3e47b0ea68: 286 hwpmc(4) support for Intel Alder Lake 6-B7, 6-BA, and 6-BF CPU 287 hwpmc(4) support for Intel Emerald Rapids CPUs 288 hwpmc(4) support for Intel Alder Lake-N CPUs 289 2901ecf01065b45: 291 New library libuvmem provides the vmem(9) API to userspace applications. 292 293b6cad334e64: 294 Make game controller devices accessible by members of the "game" group 295 by default. 296 297791c531402bd: 298 Add driver for Feature Integration Technology Inc. (aka Fintek) F81232 299 USB to serial devices. 300 301ec0cd287f55f: 302 Support for NVMe/TCP offload on Chelsio T7 adapters. The nvmf_che(4) 303 module enables T7 adapters to process NVMe/TCP PDUs directly similar to 304 the PDU offload provided by cxgbei(4) for iSCSI. 305
