1 Release notes for FreeBSD 13.0.
3 This file describes new user-visible features, changes and updates relevant to
4 users of binary FreeBSD releases. Each entry should describe the change in no
5 more than several sentences and should reference manual pages where an
6 interested user can find more information. Entries should wrap after 80
7 columns. Each entry should begin with one or more commit IDs on one line,
8 specified as a comma separated list and/or range, followed by a colon and a
9 newline. Entries should be separated by a newline.
11 Changes to this file should not be MFCed.
14 Remove support for ARC4, Blowfish, Cast, DES, Triple DES,
15 MD5-HMAC, and Skipjack algorithms from /dev/crypto.
18 Remove support for DES, Triple DES, Blowfish, Cast, and
19 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC,
20 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4).
23 Remove support for Triple DES, Blowfish, and MD5 HMAC from
27 Remove support for DES, Triple DES, and RC4 from in-kernel GSS
34 init(8), service(8), and cron(8) will now adopt user/class environment
35 variables (excluding PATH, by default, which will be overwritten) by
36 default. Notably, environment variables for all cron jobs and rc
37 services can now be set via login.conf(5).
40 sparc64 has been removed from FreeBSD.
43 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
44 (RFC-8276) to the NFS client and server.
45 NFSv4.2 is comprised of several optional features that can be supported
46 in addition to NFSv4.1. This patch adds the following optional features:
47 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
49 - intra server file range copying via the copy_file_range(2) syscall
50 --> Avoiding data tranfer over the wire to/from the NFS client.
51 - lseek(SEEK_DATA/SEEK_HOLE)
52 - Extended attribute syscalls for "user" namespace attributes as defined
55 For the client, NFSv4.2 is only used if the mount command line option
56 minorversion=2 is specified.
57 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
58 and vfs.nfsd.server_max_minorversion4 have been added that allow
59 sysadmins to limit the minor versions of NFSv4 supported by the nfsd
61 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
65 armv5 support has been removed from FreeBSD.
68 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
71 sqlite3 is updated to sqlite3-3.30.1.
74 cron(8) now supports the -n (suppress mail on succesful run) and -q
75 (suppress logging of command execution) options in the crontab format.
76 See the crontab(5) manpage for details.
79 ntpd is no longer by default locked in memory. rlimit memlock 32
80 or rlimit memlock 0 can be used to restore this behaviour.
83 Add kernel-side support for in-kernel Transport Layer Security
84 (KTLS). KTLS permits using sendfile(2) over sockets using
88 WPA is updated from 2.8 to 2.9.
91 Add probes for lockmgr(9) to the lockstat DTrace provider, add
92 corresponding lockstat(1) events, and document the new probes in
96 Intel RST is a new 'feature' that remaps NVMe devices from
97 their normal location to part of the AHCI bar space. This
98 will eliminate the need to set the BIOS SATA setting from RST
99 to AHCI causing the nvme drive to be erased before FreeBSD
100 will see the nvme drive. FreeBSD will now be able to see the
101 nvme drive now in the default config.
104 Add a vop_stdioctl() call, so that file systems that do not support
105 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
106 The algorithm appears to be compatible with the POSIX draft and
107 the implementation in Linux for the case of a file system that
108 does not support holes. Prior to this patch, lseek(2) would reply
109 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
110 file systems that do not support holes.
111 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
112 any other cases, such as a ENOTTY return from vn_bmap_seekhole().
115 The fuse driver has been renamed to fusefs(5) and been substantially
116 rewritten. The new driver includes many bug fixes and performance
117 enhancements, as well as the following user-visible features:
118 * Optional kernel-side permissions checks (-o default_permissions)
119 * mknod(2), socket(2), and pipe(2) support
120 * server side locking with fcntl(2)
121 * FUSE operations are now interruptible when mounted with -o intr
122 * server side handling of UTIME_NOW during utimensat(2)
123 * mount options may be updated with "mount -u"
124 * fusefs file system may now be exported over NFS
125 * RLIMIT_FSIZE support
126 * support for fuse file systems using protocols as old as 7.4
128 FUSE file system developers should also take note of the following new
130 * The protocol level has been raised from 7.8 to 7.23
131 * kqueue support on /dev/fuse
132 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY
135 gnop(8) can now configure a delay to be applied to read and write
136 request delays. See the -d, -q and -x parameters.
139 Adds a Linux compatible copy_file_range(2) syscall.
142 libcap_random(3) has been removed. Applications can use native
143 APIs to get random data in capability mode.
146 Add support for using unmapped mbufs with sendfile(2).
149 nand(4) and related components have been removed.
152 The UEFI loader now supports HTTP boot.
155 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
156 guests to play to and record audio data from the host.
159 swapon(8) can now erase a swap device immediately before enabling it,
160 similar to newfs(8)'s -E option. This behaviour can be specified by
161 adding -E to swapon(8)'s command-line parameters, or by adding the
162 "trimonce" option to a swap device's /etc/fstab entry.
165 The following network drivers have been removed: bm(4), cs(4), de(4),
166 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
