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 nc(1) now implements SCTP mode, enabled by specifying the --sctp option.
17 struct export_args has changed so that the "user" specified for
18 the -maproot and -mapall exports(5) options may be in more than
22 sed(1) has learned about hex escapes (e.g. \x27) and will now do the
23 right thing with them, removing the need for printf magic or obnoxious
24 escaping in many scenarios.
26 r361238, r361798, r361799:
27 ZFS will now unconditionally reject read(2) of a directory with EISDIR.
28 Additionally, read(2) of a directory is now rejected with EISDIR by
29 default and may be re-enabled for non-ZFS filesystems that allow it with
30 the sysctl(8) MIB 'security.bsd.allow_read_dir'.
32 Aliases for grep to default to '-d skip' may be desired if commonly
33 non-recursively grepping a list that includes directories and the
34 possibility of EISDIR errors in stderr is not tolerable. Example
35 aliases, commented out, have been installed in /root/.cshrc and
39 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5).
40 exec.prepare runs before mounts, so can be used to populate new jails.
41 exec.release runs after unmounts, so can be used to remove ephemeral
44 r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936:
45 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5,
46 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from
47 the kernel open cryptographic framework (OCF).
50 Remove support for ARC4, Blowfish, Cast, DES, Triple DES,
51 MD5-HMAC, and Skipjack algorithms from /dev/crypto.
54 Remove support for DES, Triple DES, Blowfish, Cast, and
55 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC,
56 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4).
59 Remove support for Triple DES, Blowfish, and MD5 HMAC from
63 Remove support for DES, Triple DES, and RC4 from in-kernel GSS
70 init(8), service(8), and cron(8) will now adopt user/class environment
71 variables (excluding PATH, by default, which will be overwritten) by
72 default. Notably, environment variables for all cron jobs and rc
73 services can now be set via login.conf(5).
76 sparc64 has been removed from FreeBSD.
79 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
80 (RFC-8276) to the NFS client and server.
81 NFSv4.2 is comprised of several optional features that can be supported
82 in addition to NFSv4.1. This patch adds the following optional features:
83 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
85 - intra server file range copying via the copy_file_range(2) syscall
86 --> Avoiding data tranfer over the wire to/from the NFS client.
87 - lseek(SEEK_DATA/SEEK_HOLE)
88 - Extended attribute syscalls for "user" namespace attributes as defined
91 For the client, NFSv4.2 is only used if the mount command line option
92 minorversion=2 is specified.
93 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
94 and vfs.nfsd.server_max_minorversion4 have been added that allow
95 sysadmins to limit the minor versions of NFSv4 supported by the nfsd
97 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
101 armv5 support has been removed from FreeBSD.
104 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
107 sqlite3 is updated to sqlite3-3.30.1.
110 cron(8) now supports the -n (suppress mail on succesful run) and -q
111 (suppress logging of command execution) options in the crontab format.
112 See the crontab(5) manpage for details.
115 ntpd is no longer by default locked in memory. rlimit memlock 32
116 or rlimit memlock 0 can be used to restore this behaviour.
118 r351770,r352920,r352922,r352923:
119 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync,
120 and iflag=fullblock flags, compatible with illumos and GNU.
123 Add kernel-side support for in-kernel Transport Layer Security
124 (KTLS). KTLS permits using sendfile(2) over sockets using
128 WPA is updated from 2.8 to 2.9.
131 Add probes for lockmgr(9) to the lockstat DTrace provider, add
132 corresponding lockstat(1) events, and document the new probes in
136 Intel RST is a new 'feature' that remaps NVMe devices from
137 their normal location to part of the AHCI bar space. This
138 will eliminate the need to set the BIOS SATA setting from RST
139 to AHCI causing the nvme drive to be erased before FreeBSD
140 will see the nvme drive. FreeBSD will now be able to see the
141 nvme drive now in the default config.
144 Add a vop_stdioctl() call, so that file systems that do not support
145 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
146 The algorithm appears to be compatible with the POSIX draft and
147 the implementation in Linux for the case of a file system that
148 does not support holes. Prior to this patch, lseek(2) would reply
149 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
150 file systems that do not support holes.
151 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
152 any other cases, such as a ENOTTY return from vn_bmap_seekhole().
155 The fuse driver has been renamed to fusefs(5) and been substantially
156 rewritten. The new driver includes many bug fixes and performance
157 enhancements, as well as the following user-visible features:
158 * Optional kernel-side permissions checks (-o default_permissions)
159 * mknod(2), socket(2), and pipe(2) support
160 * server side locking with fcntl(2)
161 * FUSE operations are now interruptible when mounted with -o intr
162 * server side handling of UTIME_NOW during utimensat(2)
163 * mount options may be updated with "mount -u"
164 * fusefs file system may now be exported over NFS
165 * RLIMIT_FSIZE support
166 * support for fuse file systems using protocols as old as 7.4
168 FUSE file system developers should also take note of the following new
170 * The protocol level has been raised from 7.8 to 7.23
171 * kqueue support on /dev/fuse
172 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY
175 gnop(8) can now configure a delay to be applied to read and write
176 request delays. See the -d, -q and -x parameters.
179 Adds a Linux compatible copy_file_range(2) syscall.
182 libcap_random(3) has been removed. Applications can use native
183 APIs to get random data in capability mode.
186 Add support for using unmapped mbufs with sendfile(2).
189 nand(4) and related components have been removed.
192 The UEFI loader now supports HTTP boot.
195 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
196 guests to play to and record audio data from the host.
199 swapon(8) can now erase a swap device immediately before enabling it,
200 similar to newfs(8)'s -E option. This behaviour can be specified by
201 adding -E to swapon(8)'s command-line parameters, or by adding the
202 "trimonce" option to a swap device's /etc/fstab entry.
205 The following network drivers have been removed: bm(4), cs(4), de(4),
206 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
210 Wired page accounting has been split into kernel wirings and user
211 wirings (e.g., by mlock(2)). Kernel wirings no long count towards
212 the global limit, which is renamed to vm.max_user_wired. bhyve -S
213 allocates user-wired memory and is now subject to that limit.
