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 ZFS will now reject read(2) of a dirfd with EISDIR.
16 r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936:
17 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5,
18 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from
19 the kernel open cryptographic framework (OCF).
22 Remove support for ARC4, Blowfish, Cast, DES, Triple DES,
23 MD5-HMAC, and Skipjack algorithms from /dev/crypto.
26 Remove support for DES, Triple DES, Blowfish, Cast, and
27 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC,
28 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4).
31 Remove support for Triple DES, Blowfish, and MD5 HMAC from
35 Remove support for DES, Triple DES, and RC4 from in-kernel GSS
42 init(8), service(8), and cron(8) will now adopt user/class environment
43 variables (excluding PATH, by default, which will be overwritten) by
44 default. Notably, environment variables for all cron jobs and rc
45 services can now be set via login.conf(5).
48 sparc64 has been removed from FreeBSD.
51 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
52 (RFC-8276) to the NFS client and server.
53 NFSv4.2 is comprised of several optional features that can be supported
54 in addition to NFSv4.1. This patch adds the following optional features:
55 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
57 - intra server file range copying via the copy_file_range(2) syscall
58 --> Avoiding data tranfer over the wire to/from the NFS client.
59 - lseek(SEEK_DATA/SEEK_HOLE)
60 - Extended attribute syscalls for "user" namespace attributes as defined
63 For the client, NFSv4.2 is only used if the mount command line option
64 minorversion=2 is specified.
65 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
66 and vfs.nfsd.server_max_minorversion4 have been added that allow
67 sysadmins to limit the minor versions of NFSv4 supported by the nfsd
69 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
73 armv5 support has been removed from FreeBSD.
76 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
79 sqlite3 is updated to sqlite3-3.30.1.
82 cron(8) now supports the -n (suppress mail on succesful run) and -q
83 (suppress logging of command execution) options in the crontab format.
84 See the crontab(5) manpage for details.
87 ntpd is no longer by default locked in memory. rlimit memlock 32
88 or rlimit memlock 0 can be used to restore this behaviour.
90 r351770,r352920,r352922,r352923:
91 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync,
92 and iflag=fullblock flags, compatible with illumos and GNU.
95 Add kernel-side support for in-kernel Transport Layer Security
96 (KTLS). KTLS permits using sendfile(2) over sockets using
100 WPA is updated from 2.8 to 2.9.
103 Add probes for lockmgr(9) to the lockstat DTrace provider, add
104 corresponding lockstat(1) events, and document the new probes in
108 Intel RST is a new 'feature' that remaps NVMe devices from
109 their normal location to part of the AHCI bar space. This
110 will eliminate the need to set the BIOS SATA setting from RST
111 to AHCI causing the nvme drive to be erased before FreeBSD
112 will see the nvme drive. FreeBSD will now be able to see the
113 nvme drive now in the default config.
116 Add a vop_stdioctl() call, so that file systems that do not support
117 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
118 The algorithm appears to be compatible with the POSIX draft and
119 the implementation in Linux for the case of a file system that
120 does not support holes. Prior to this patch, lseek(2) would reply
121 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
122 file systems that do not support holes.
123 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
124 any other cases, such as a ENOTTY return from vn_bmap_seekhole().
127 The fuse driver has been renamed to fusefs(5) and been substantially
128 rewritten. The new driver includes many bug fixes and performance
129 enhancements, as well as the following user-visible features:
130 * Optional kernel-side permissions checks (-o default_permissions)
131 * mknod(2), socket(2), and pipe(2) support
132 * server side locking with fcntl(2)
133 * FUSE operations are now interruptible when mounted with -o intr
134 * server side handling of UTIME_NOW during utimensat(2)
135 * mount options may be updated with "mount -u"
136 * fusefs file system may now be exported over NFS
137 * RLIMIT_FSIZE support
138 * support for fuse file systems using protocols as old as 7.4
140 FUSE file system developers should also take note of the following new
142 * The protocol level has been raised from 7.8 to 7.23
143 * kqueue support on /dev/fuse
144 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY
147 gnop(8) can now configure a delay to be applied to read and write
148 request delays. See the -d, -q and -x parameters.
151 Adds a Linux compatible copy_file_range(2) syscall.
154 libcap_random(3) has been removed. Applications can use native
155 APIs to get random data in capability mode.
158 Add support for using unmapped mbufs with sendfile(2).
161 nand(4) and related components have been removed.
164 The UEFI loader now supports HTTP boot.
167 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
168 guests to play to and record audio data from the host.
171 swapon(8) can now erase a swap device immediately before enabling it,
172 similar to newfs(8)'s -E option. This behaviour can be specified by
173 adding -E to swapon(8)'s command-line parameters, or by adding the
174 "trimonce" option to a swap device's /etc/fstab entry.
177 The following network drivers have been removed: bm(4), cs(4), de(4),
178 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
182 Wired page accounting has been split into kernel wirings and user
183 wirings (e.g., by mlock(2)). Kernel wirings no long count towards
184 the global limit, which is renamed to vm.max_user_wired. bhyve -S
185 allocates user-wired memory and is now subject to that limit.
