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 13af099eaa5ec: 14 Users belonging to the new vmm group can now create bhyve VMs. See the 15 vmm(4) man page for details. 16 17c71354030a2: 18 Users wishing to use bhyve PCI passthrough in jails must create the 19 jail with the allow.vmm_ppt option configured. 20 214d707825bf62: 22 The pdwait(2) system call was added. It provides wait(2)-like 23 functionality for a process descriptor (see procdesc(4)). 24 255c2ee618d5ec: 26 The pdrfork(2) system call was added. It behaves like rfork(2) but 27 additionally returns a process descriptor (see procdesc(4)). 28 2941ccf82b29f3, 591c7a08bf8a: 30 On arm64, memcpy(3), memmove(3) and memset(3) are now implemented using 31 the MOPS (Memory Operations) feature instructions when they are 32 implemented by the system. 33 343f0aea09689f: 35 posix_spawnattr_getexecfd_np(3) and posix_spawnattr_setexecfd_np(3) 36 functions were added to libc. The latter causes posix_spawn(3) to 37 call fexecve(2) on the specified file descriptor rather than executing 38 the file at the provided path. 39 40fb4b0c911951: 41 witness(4) now prints additional information to the system console when 42 a lock order reversal is detected, making debugging such issues easier. 43 441322760fd127: 45 It is now possible to compile both the 4BSD and ULE schedulers into the 46 same kernel. The scheduler is selectable at boot-time using a tunable. 47 See the SCHEDULERS section of the tuning(7) man page for details. 48 49627e126dbb07: 50 The default value of the net.inet6.ip6.connect_in6addr_wild has changed 51 to 0. This means that connecting to the all-zeroes IPv6 address no longer 52 implicitly results in a loopback connection. 53 54afa70a8496e9: 55 The pthread_tryjoin_np(3) function was added to libthr(3). It provides 56 the same functionality as pthread_join(3) but returns instead of 57 blocking if the target thread has not yet exited. 58 59ecc039be7fdd: 60 NanoBSD images can now be built as a non-root user. 61 627f54c65abc67: 63 Update smartpqi(4) to vendor version 14.4690.0.2008 - 15.2.0.2008 64 for the SmartArray storage controllers. This adds support for new 65 controllers, adds code that utilizes the new BIG_IOCTL_Command_struct 66 and allows the I/O buffer size for a single passthrough ioctl to be 67 stored as a 32 bit integer instead of the original 16 bit integer. 68 69b0d997095022: 70 The pf firewall now supports passing IPv6 packets to divert(4) 71 sockets via divert-to actions. 72 730fa7b3bee72e, c71f18998e0b, 4162a419a475, f5a77dc8f8df: 74 LinuxKPI based wireless drivers, especially iwlwifi(4) are now 75 supported on RISC-V. 76 778254b0dec02b3, bd55cbb50c588: 78 The mac(4) framework has been extended to support jail operations, 79 allowing a policy to constrain jail creation, modification, removal, and 80 attachment. Jails have additionally been made a first-class mac(4) 81 object, and a mac.label jail(8) property has been added to facilitate 82 administration of their labels. 83 84c558eca47970: 85 The smartpqi(4) driver was updated to vendor version 4660.0.2002 86 for the SmartArry storage controllers. 87 88493d26c58e73: 89 The aq(4) driver was added, imported from the vendor repository. 90 This provides support for Aquantia / Marvell PCIe 1/2.5/5/10 Gigabit 91 Ethernet adapters (AQC107, AQC108, AQC109, AQC111, AQC112). 92 931a7151f79664: 94 A new CAM provider was added to dtrace. This enables tracing of I/O 95 requests through the CAM layer without relying on fragile function 96 boundary tracing. See dtrace_cam(4) for details. 97 98b8c99e7d912f: 99 The tdestroy(3) function was added to libc. The tdestroy() function 100 destroys a whole search tree, freeing all allocated nodes. 101 1024bf8ce037dc8: 103 The rge(4) driver was added, ported from OpenBSD. This provides 104 support for RealTek RTL8125, RTL8126 and RTL8127 PCIe Ethernet 105 controllers. 106 107cbc6f7e941e4: 108 bhyve(8)'s VNC device can now listen on a unix(4) socket for VNC client 109 connections. 110 11139ee24182b92: 112 An rc(8) service can now be started as a specific user for auditing 113 purposes by setting the <service>_audit_user rc.conf(5) variable. 114 115dcb0790bad43: 116 A setaudit(8) utility was added to the base system. This provides a 117 simple command-line wrapper for the setaudit(2) and setaudit_addr(2) 118 system calls. 119 1208e3fd450cc53, 949cff4dceff, 0e724de9ed6f, 9f49f436a9ec, e35191ccf3b3: 121 Add support for an extension to NFSv4.2 (RFCnnnn) that 122 supports handling of POSIX draft ACLs via getfacl(1)/setfacl(1). 123 124dbac191956f9, fe21dbf70aa8: 125 Support for the kcmp(2) system call and fcntl(F_DUPFD_QUERY) for Linux 126 binaries. 127 128a86dc94b84d1: 129 tzdata2025c was imported. 130 131a98e5d785001: 132 Add strdupa(3) and strndupa(3) macros for compatability with glibc. 133 134e967a2a03677: 135 divert socket compat removal, consumers must use PF_DIVERT instead of 136 PF_INET. 137 1384453ec5b8716b, 2a3b1641756a: 139 The reboot(8) and halt(8) commands now perform a graceful shutdown similar 140 to the shutdown(8) command including invoking rc.d scripts to shutdown 141 services. The fastboot(8) and fasthalt(8) commands still perform a "fast" 142 reboot or shutdown. 143 144d9788eabffa4: 145 ipfilter cannot be used in a jail by default. 146 1470ff0c19e7f70: 148 ipfs(8) is no longer built by default. 149 150575efcfff22f: 151 sendfile(2)'s SF_SYNC flag was removed. 152 153057dae35ffc6, 51a01f3debff, ca3e47b0ea68: 154 hwpmc(4) support for Intel Alder Lake 6-B7, 6-BA, and 6-BF CPU 155 hwpmc(4) support for Intel Emerald Rapids CPUs 156 hwpmc(4) support for Intel Alder Lake-N CPUs 157 1581ecf01065b45: 159 New library libuvmem provides the vmem(9) API to userspace applications. 160 161b6cad334e64: 162 Make game controller devices accessible by members of the "game" group 163 by default. 164 165791c531402bd: 166 Add driver for Feature Integration Technology Inc. (aka Fintek) F81232 167 USB to serial devices. 168 169ec0cd287f55f: 170 Support for NVMe/TCP offload on Chelsio T7 adapters. The nvmf_che(4) 171 module enables T7 adapters to process NVMe/TCP PDUs directly similar to 172 the PDU offload provided by cxgbei(4) for iSCSI. 173
