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 13ab9257599a5: 14 The src.conf(5) options WITHOUT_BZIP2 and WITHOUT_BZIP2_SUPPORT 15 have been removed. 16 17af099eaa5ec: 18 Users belonging to the new vmm group can now create bhyve VMs. See the 19 vmm(4) man page for details. 20 21c71354030a2: 22 Users wishing to use bhyve PCI passthrough in jails must create the 23 jail with the allow.vmm_ppt option configured. 24 254d707825bf62: 26 The pdwait(2) system call was added. It provides wait(2)-like 27 functionality for a process descriptor (see procdesc(4)). 28 295c2ee618d5ec: 30 The pdrfork(2) system call was added. It behaves like rfork(2) but 31 additionally returns a process descriptor (see procdesc(4)). 32 3341ccf82b29f3, 591c7a08bf8a: 34 On arm64, memcpy(3), memmove(3) and memset(3) are now implemented using 35 the MOPS (Memory Operations) feature instructions when they are 36 implemented by the system. 37 383f0aea09689f: 39 posix_spawnattr_getexecfd_np(3) and posix_spawnattr_setexecfd_np(3) 40 functions were added to libc. The latter causes posix_spawn(3) to 41 call fexecve(2) on the specified file descriptor rather than executing 42 the file at the provided path. 43 44fb4b0c911951: 45 witness(4) now prints additional information to the system console when 46 a lock order reversal is detected, making debugging such issues easier. 47 481322760fd127: 49 It is now possible to compile both the 4BSD and ULE schedulers into the 50 same kernel. The scheduler is selectable at boot-time using a tunable. 51 See the SCHEDULERS section of the tuning(7) man page for details. 52 53627e126dbb07: 54 The default value of the net.inet6.ip6.connect_in6addr_wild has changed 55 to 0. This means that connecting to the all-zeroes IPv6 address no longer 56 implicitly results in a loopback connection. 57 58afa70a8496e9: 59 The pthread_tryjoin_np(3) function was added to libthr(3). It provides 60 the same functionality as pthread_join(3) but returns instead of 61 blocking if the target thread has not yet exited. 62 63ecc039be7fdd: 64 NanoBSD images can now be built as a non-root user. 65 667f54c65abc67: 67 Update smartpqi(4) to vendor version 14.4690.0.2008 - 15.2.0.2008 68 for the SmartArray storage controllers. This adds support for new 69 controllers, adds code that utilizes the new BIG_IOCTL_Command_struct 70 and allows the I/O buffer size for a single passthrough ioctl to be 71 stored as a 32 bit integer instead of the original 16 bit integer. 72 73b0d997095022: 74 The pf firewall now supports passing IPv6 packets to divert(4) 75 sockets via divert-to actions. 76 770fa7b3bee72e, c71f18998e0b, 4162a419a475, f5a77dc8f8df: 78 LinuxKPI based wireless drivers, especially iwlwifi(4) are now 79 supported on RISC-V. 80 818254b0dec02b3, bd55cbb50c588: 82 The mac(4) framework has been extended to support jail operations, 83 allowing a policy to constrain jail creation, modification, removal, and 84 attachment. Jails have additionally been made a first-class mac(4) 85 object, and a mac.label jail(8) property has been added to facilitate 86 administration of their labels. 87 88c558eca47970: 89 The smartpqi(4) driver was updated to vendor version 4660.0.2002 90 for the SmartArry storage controllers. 91 92493d26c58e73: 93 The aq(4) driver was added, imported from the vendor repository. 94 This provides support for Aquantia / Marvell PCIe 1/2.5/5/10 Gigabit 95 Ethernet adapters (AQC107, AQC108, AQC109, AQC111, AQC112). 96 971a7151f79664: 98 A new CAM provider was added to dtrace. This enables tracing of I/O 99 requests through the CAM layer without relying on fragile function 100 boundary tracing. See dtrace_cam(4) for details. 101 102b8c99e7d912f: 103 The tdestroy(3) function was added to libc. The tdestroy() function 104 destroys a whole search tree, freeing all allocated nodes. 105 1064bf8ce037dc8: 107 The rge(4) driver was added, ported from OpenBSD. This provides 108 support for RealTek RTL8125, RTL8126 and RTL8127 PCIe Ethernet 109 controllers. 110 111cbc6f7e941e4: 112 bhyve(8)'s VNC device can now listen on a unix(4) socket for VNC client 113 connections. 114 11539ee24182b92: 116 An rc(8) service can now be started as a specific user for auditing 117 purposes by setting the <service>_audit_user rc.conf(5) variable. 118 119dcb0790bad43: 120 A setaudit(8) utility was added to the base system. This provides a 121 simple command-line wrapper for the setaudit(2) and setaudit_addr(2) 122 system calls. 123 1248e3fd450cc53, 949cff4dceff, 0e724de9ed6f, 9f49f436a9ec, e35191ccf3b3: 125 Add support for an extension to NFSv4.2 (RFCnnnn) that 126 supports handling of POSIX draft ACLs via getfacl(1)/setfacl(1). 127 128dbac191956f9, fe21dbf70aa8: 129 Support for the kcmp(2) system call and fcntl(F_DUPFD_QUERY) for Linux 130 binaries. 131 132a86dc94b84d1: 133 tzdata2025c was imported. 134 135a98e5d785001: 136 Add strdupa(3) and strndupa(3) macros for compatability with glibc. 137 138e967a2a03677: 139 divert socket compat removal, consumers must use PF_DIVERT instead of 140 PF_INET. 141 1424453ec5b8716b, 2a3b1641756a: 143 The reboot(8) and halt(8) commands now perform a graceful shutdown similar 144 to the shutdown(8) command including invoking rc.d scripts to shutdown 145 services. The fastboot(8) and fasthalt(8) commands still perform a "fast" 146 reboot or shutdown. 147 148d9788eabffa4: 149 ipfilter cannot be used in a jail by default. 150 1510ff0c19e7f70: 152 ipfs(8) is no longer built by default. 153 154575efcfff22f: 155 sendfile(2)'s SF_SYNC flag was removed. 156 157057dae35ffc6, 51a01f3debff, ca3e47b0ea68: 158 hwpmc(4) support for Intel Alder Lake 6-B7, 6-BA, and 6-BF CPU 159 hwpmc(4) support for Intel Emerald Rapids CPUs 160 hwpmc(4) support for Intel Alder Lake-N CPUs 161 1621ecf01065b45: 163 New library libuvmem provides the vmem(9) API to userspace applications. 164 165b6cad334e64: 166 Make game controller devices accessible by members of the "game" group 167 by default. 168 169791c531402bd: 170 Add driver for Feature Integration Technology Inc. (aka Fintek) F81232 171 USB to serial devices. 172 173ec0cd287f55f: 174 Support for NVMe/TCP offload on Chelsio T7 adapters. The nvmf_che(4) 175 module enables T7 adapters to process NVMe/TCP PDUs directly similar to 176 the PDU offload provided by cxgbei(4) for iSCSI. 177
