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 13r359786-r359787: 14 Remove support for DES, Triple DES, and RC4 from in-kernel GSS 15 authentication. 16 17r357627: 18 remove elf2aout. 19 20r357560-r357565: 21 init(8), service(8), and cron(8) will now adopt user/class environment 22 variables (excluding PATH, by default, which will be overwritten) by 23 default. Notably, environment variables for all cron jobs and rc 24 services can now be set via login.conf(5). 25 26r357455: 27 sparc64 has been removed from FreeBSD. 28 29r355677: 30 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes 31 (RFC-8276) to the NFS client and server. 32 NFSv4.2 is comprised of several optional features that can be supported 33 in addition to NFSv4.1. This patch adds the following optional features: 34 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED) 35 - posix_fallocate() 36 - intra server file range copying via the copy_file_range(2) syscall 37 --> Avoiding data tranfer over the wire to/from the NFS client. 38 - lseek(SEEK_DATA/SEEK_HOLE) 39 - Extended attribute syscalls for "user" namespace attributes as defined 40 by RFC-8276. 41 42 For the client, NFSv4.2 is only used if the mount command line option 43 minorversion=2 is specified. 44 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4 45 and vfs.nfsd.server_max_minorversion4 have been added that allow 46 sysadmins to limit the minor versions of NFSv4 supported by the nfsd 47 server. 48 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2 49 on the server. 50 51r356263: 52 armv5 support has been removed from FreeBSD. 53 54r354517: 55 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices. 56 57r354269: 58 sqlite3 is updated to sqlite3-3.30.1. 59 60r352668: 61 cron(8) now supports the -n (suppress mail on succesful run) and -q 62 (suppress logging of command execution) options in the crontab format. 63 See the crontab(5) manpage for details. 64 65r352304: 66 ntpd is no longer by default locked in memory. rlimit memlock 32 67 or rlimit memlock 0 can be used to restore this behaviour. 68 69r351522: 70 Add kernel-side support for in-kernel Transport Layer Security 71 (KTLS). KTLS permits using sendfile(2) over sockets using 72 TLS. 73 74r351397: 75 WPA is updated from 2.8 to 2.9. 76 77r351361: 78 Add probes for lockmgr(9) to the lockstat DTrace provider, add 79 corresponding lockstat(1) events, and document the new probes in 80 dtrace_lockstat.4. 81 82r351356: 83 Intel RST is a new 'feature' that remaps NVMe devices from 84 their normal location to part of the AHCI bar space. This 85 will eliminate the need to set the BIOS SATA setting from RST 86 to AHCI causing the nvme drive to be erased before FreeBSD 87 will see the nvme drive. FreeBSD will now be able to see the 88 nvme drive now in the default config. 89 90r351201, r351372: 91 Add a vop_stdioctl() call, so that file systems that do not support 92 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE). 93 The algorithm appears to be compatible with the POSIX draft and 94 the implementation in Linux for the case of a file system that 95 does not support holes. Prior to this patch, lseek(2) would reply 96 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in 97 file systems that do not support holes. 98 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for 99 any other cases, such as a ENOTTY return from vn_bmap_seekhole(). 100 101r350665: 102 The fuse driver has been renamed to fusefs(5) and been substantially 103 rewritten. The new driver includes many bug fixes and performance 104 enhancements, as well as the following user-visible features: 105 * Optional kernel-side permissions checks (-o default_permissions) 106 * mknod(2), socket(2), and pipe(2) support 107 * server side locking with fcntl(2) 108 * FUSE operations are now interruptible when mounted with -o intr 109 * server side handling of UTIME_NOW during utimensat(2) 110 * mount options may be updated with "mount -u" 111 * fusefs file system may now be exported over NFS 112 * RLIMIT_FSIZE support 113 * support for fuse file systems using protocols as old as 7.4 114 115 FUSE file system developers should also take note of the following new 116 features: 117 * The protocol level has been raised from 7.8 to 7.23 118 * kqueue support on /dev/fuse 119 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY 120 121r350471: 122 gnop(8) can now configure a delay to be applied to read and write 123 request delays. See the -d, -q and -x parameters. 124 125r350315, r350316: 126 Adds a Linux compatible copy_file_range(2) syscall. 127 128r350307: 129 libcap_random(3) has been removed. Applications can use native 130 APIs to get random data in capability mode. 131 132r349529,r349530: 133 Add support for using unmapped mbufs with sendfile(2). 134 135r349352: 136 nand(4) and related components have been removed. 137 138r349349: 139 The UEFI loader now supports HTTP boot. 140 141r349335: 142 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing 143 guests to play to and record audio data from the host. 144 145r349286: 146 swapon(8) can now erase a swap device immediately before enabling it, 147 similar to newfs(8)'s -E option. This behaviour can be specified by 148 adding -E to swapon(8)'s command-line parameters, or by adding the 149 "trimonce" option to a swap device's /etc/fstab entry. 150 151r347908-r347923: 152 The following network drivers have been removed: bm(4), cs(4), de(4), 153 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4), 154 vx(4), wb(4), xe(4). 155 156$FreeBSD$ 157
