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