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