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 134d707825bf62: 14 The pdwait(2) system call was added. It provides wait(2)-like 15 functionality for a process descriptor (see procdesc(4)). 16 175c2ee618d5ec: 18 The pdrfork(2) system call was added. It behaves like rfork(2) but 19 additionally returns a process descriptor (see procdesc(4)). 20 2141ccf82b29f3, 591c7a08bf8a: 22 On arm64, memcpy(3), memmove(3) and memset(3) are now implemented using 23 the MOPS (Memory Operations) feature instructions when they are 24 implemented by the system. 25 263f0aea09689f: 27 posix_spawnattr_getexecfd_np(3) and posix_spawnattr_setexecfd_np(3) 28 functions were added to libc. The latter causes posix_spawn(3) to 29 call fexecve(2) on the specified file descriptor rather than executing 30 the file at the provided path. 31 32fb4b0c911951: 33 witness(4) now prints additional information to the system console when 34 a lock order reversal is detected, making debugging such issues easier. 35 361322760fd127: 37 It is now possible to compile both the 4BSD and ULE schedulers into the 38 same kernel. The scheduler is selectable at boot-time using a tunable. 39 See the SCHEDULERS section of the tuning(7) man page for details. 40 41627e126dbb07: 42 The default value of the net.inet6.ip6.connect_in6addr_wild has changed 43 to 0. This means that connecting to the all-zeroes IPv6 address no longer 44 implicitly results in a loopback connection. 45 46afa70a8496e9: 47 The pthread_tryjoin_np(3) function was added to libthr(3). It provides 48 the same functionality as pthread_join(3) but returns instead of 49 blocking if the target thread has not yet exited. 50 51ecc039be7fdd: 52 NanoBSD images can now be built as a non-root user. 53 547f54c65abc67: 55 Update smartpqi(4) to vendor version 14.4690.0.2008 - 15.2.0.2008 56 for the SmartArray storage controllers. This adds support for new 57 controllers, adds code that utilizes the new BIG_IOCTL_Command_struct 58 and allows the I/O buffer size for a single passthrough ioctl to be 59 stored as a 32 bit integer instead of the original 16 bit integer. 60 61b0d997095022: 62 The pf firewall now supports passing IPv6 packets to divert(4) 63 sockets via divert-to actions. 64 650fa7b3bee72e, c71f18998e0b, 4162a419a475, f5a77dc8f8df: 66 LinuxKPI based wireless drivers, especially iwlwifi(4) are now 67 supported on RISC-V. 68 698254b0dec02b3, bd55cbb50c588: 70 The mac(4) framework has been extended to support jail operations, 71 allowing a policy to constrain jail creation, modification, removal, and 72 attachment. Jails have additionally been made a first-class mac(4) 73 object, and a mac.label jail(8) property has been added to facilitate 74 administration of their labels. 75 76c558eca47970: 77 The smartpqi(4) driver was updated to vendor version 4660.0.2002 78 for the SmartArry storage controllers. 79 80493d26c58e73: 81 The aq(4) driver was added, imported from the vendor repository. 82 This provides support for Aquantia / Marvell PCIe 1/2.5/5/10 Gigabit 83 Ethernet adapters (AQC107, AQC108, AQC109, AQC111, AQC112). 84 851a7151f79664: 86 A new CAM provider was added to dtrace. This enables tracing of I/O 87 requests through the CAM layer without relying on fragile function 88 boundary tracing. See dtrace_cam(4) for details. 89 90b8c99e7d912f: 91 The tdestroy(3) function was added to libc. The tdestroy() function 92 destroys a whole search tree, freeing all allocated nodes. 93 944bf8ce037dc8: 95 The rge(4) driver was added, ported from OpenBSD. This provides 96 support for RealTek RTL8125, RTL8126 and RTL8127 PCIe Ethernet 97 controllers. 98 99cbc6f7e941e4: 100 bhyve(8)'s VNC device can now listen on a unix(4) socket for VNC client 101 connections. 102 10339ee24182b92: 104 An rc(8) service can now be started as a specific user for auditing 105 purposes by setting the <service>_audit_user rc.conf(5) variable. 106 107dcb0790bad43: 108 A setaudit(8) utility was added to the base system. This provides a 109 simple command-line wrapper for the setaudit(2) and setaudit_addr(2) 110 system calls. 111 1128e3fd450cc53, 949cff4dceff, 0e724de9ed6f, 9f49f436a9ec, e35191ccf3b3: 113 Add support for an extension to NFSv4.2 (RFCnnnn) that 114 supports handling of POSIX draft ACLs via getfacl(1)/setfacl(1). 115 116dbac191956f9, fe21dbf70aa8: 117 Support for the kcmp(2) system call and fcntl(F_DUPFD_QUERY) for Linux 118 binaries. 119 120a86dc94b84d1: 121 tzdata2025c was imported. 122 123a98e5d785001: 124 Add strdupa(3) and strndupa(3) macros for compatability with glibc. 125 126e967a2a03677: 127 divert socket compat removal, consumers must use PF_DIVERT instead of 128 PF_INET. 129 1304453ec5b8716b, 2a3b1641756a: 131 The reboot(8) and halt(8) commands now perform a graceful shutdown similar 132 to the shutdown(8) command including invoking rc.d scripts to shutdown 133 services. The fastboot(8) and fasthalt(8) commands still perform a "fast" 134 reboot or shutdown. 135 136d9788eabffa4: 137 ipfilter cannot be used in a jail by default. 138 1390ff0c19e7f70: 140 ipfs(8) is no longer built by default. 141 142575efcfff22f: 143 sendfile(2)'s SF_SYNC flag was removed. 144 145057dae35ffc6, 51a01f3debff, ca3e47b0ea68: 146 hwpmc(4) support for Intel Alder Lake 6-B7, 6-BA, and 6-BF CPU 147 hwpmc(4) support for Intel Emerald Rapids CPUs 148 hwpmc(4) support for Intel Alder Lake-N CPUs 149 1501ecf01065b45: 151 New library libuvmem provides the vmem(9) API to userspace applications. 152 153b6cad334e64: 154 Make game controller devices accessible by members of the "game" group 155 by default. 156 157791c531402bd: 158 Add driver for Feature Integration Technology Inc. (aka Fintek) F81232 159 USB to serial devices. 160 161ec0cd287f55f: 162 Support for NVMe/TCP offload on Chelsio T7 adapters. The nvmf_che(4) 163 module enables T7 adapters to process NVMe/TCP PDUs directly similar to 164 the PDU offload provided by cxgbei(4) for iSCSI. 165
