1Release notes for FreeBSD 13.0. 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 13r357627: 14 remove elf2aout. 15 16r357560-r357565: 17 init(8), service(8), and cron(8) will now adopt user/class environment 18 variables (excluding PATH, by default, which will be overwritten) by 19 default. Notably, environment variables for all cron jobs and rc 20 services can now be set via login.conf(5). 21 22r357455: 23 sparc64 has been removed from FreeBSD. 24 25r355677: 26 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes 27 (RFC-8276) to the NFS client and server. 28 NFSv4.2 is comprised of several optional features that can be supported 29 in addition to NFSv4.1. This patch adds the following optional features: 30 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED) 31 - posix_fallocate() 32 - intra server file range copying via the copy_file_range(2) syscall 33 --> Avoiding data tranfer over the wire to/from the NFS client. 34 - lseek(SEEK_DATA/SEEK_HOLE) 35 - Extended attribute syscalls for "user" namespace attributes as defined 36 by RFC-8276. 37 38 For the client, NFSv4.2 is only used if the mount command line option 39 minorversion=2 is specified. 40 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4 41 and vfs.nfsd.server_max_minorversion4 have been added that allow 42 sysadmins to limit the minor versions of NFSv4 supported by the nfsd 43 server. 44 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2 45 on the server. 46 47r356263: 48 armv5 support has been removed from FreeBSD. 49 50r354517: 51 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices. 52 53r354269: 54 sqlite3 is updated to sqlite3-3.30.1. 55 56r352668: 57 cron(8) now supports the -n (suppress mail on succesful run) and -q 58 (suppress logging of command execution) options in the crontab format. 59 See the crontab(5) manpage for details. 60 61r352304: 62 ntpd is no longer by default locked in memory. rlimit memlock 32 63 or rlimit memlock 0 can be used to restore this behaviour. 64 65r351522: 66 Add kernel-side support for in-kernel Transport Layer Security 67 (KTLS). KTLS permits using sendfile(2) over sockets using 68 TLS. 69 70r351397: 71 WPA is updated from 2.8 to 2.9. 72 73r351361: 74 Add probes for lockmgr(9) to the lockstat DTrace provider, add 75 corresponding lockstat(1) events, and document the new probes in 76 dtrace_lockstat.4. 77 78r351356: 79 Intel RST is a new 'feature' that remaps NVMe devices from 80 their normal location to part of the AHCI bar space. This 81 will eliminate the need to set the BIOS SATA setting from RST 82 to AHCI causing the nvme drive to be erased before FreeBSD 83 will see the nvme drive. FreeBSD will now be able to see the 84 nvme drive now in the default config. 85 86r351201, r351372: 87 Add a vop_stdioctl() call, so that file systems that do not support 88 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE). 89 The algorithm appears to be compatible with the POSIX draft and 90 the implementation in Linux for the case of a file system that 91 does not support holes. Prior to this patch, lseek(2) would reply 92 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in 93 file systems that do not support holes. 94 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for 95 any other cases, such as a ENOTTY return from vn_bmap_seekhole(). 96 97r350665: 98 The fuse driver has been renamed to fusefs(5) and been substantially 99 rewritten. The new driver includes many bug fixes and performance 100 enhancements, as well as the following user-visible features: 101 * Optional kernel-side permissions checks (-o default_permissions) 102 * mknod(2), socket(2), and pipe(2) support 103 * server side locking with fcntl(2) 104 * FUSE operations are now interruptible when mounted with -o intr 105 * server side handling of UTIME_NOW during utimensat(2) 106 * mount options may be updated with "mount -u" 107 * fusefs file system may now be exported over NFS 108 * RLIMIT_FSIZE support 109 * support for fuse file systems using protocols as old as 7.4 110 111 FUSE file system developers should also take note of the following new 112 features: 113 * The protocol level has been raised from 7.8 to 7.23 114 * kqueue support on /dev/fuse 115 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY 116 117r350471: 118 gnop(8) can now configure a delay to be applied to read and write 119 request delays. See the -d, -q and -x parameters. 120 121r350315, r350316: 122 Adds a Linux compatible copy_file_range(2) syscall. 123 124r350307: 125 libcap_random(3) has been removed. Applications can use native 126 APIs to get random data in capability mode. 127 128r349529,r349530: 129 Add support for using unmapped mbufs with sendfile(2). 130 131r349352: 132 nand(4) and related components have been removed. 133 134r349349: 135 The UEFI loader now supports HTTP boot. 136 137r349335: 138 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing 139 guests to play to and record audio data from the host. 140 141r349286: 142 swapon(8) can now erase a swap device immediately before enabling it, 143 similar to newfs(8)'s -E option. This behaviour can be specified by 144 adding -E to swapon(8)'s command-line parameters, or by adding the 145 "trimonce" option to a swap device's /etc/fstab entry. 146 147r347908-r347923: 148 The following network drivers have been removed: bm(4), cs(4), de(4), 149 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4), 150 vx(4), wb(4), xe(4). 151 152$FreeBSD$ 153
