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 Applications using regex(3), e.g. sed/grep, will no longer accept
15 redundant escapes for most ordinary characters.
18 SCTP support has been removed from GENERIC kernel configurations.
19 The SCTP stack is now built as sctp.ko and can be dynamically loaded.
22 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details.
25 The safexcel(4) crypto offload driver has been added.
28 nc(1) now implements SCTP mode, enabled by specifying the --sctp option.
31 struct export_args has changed so that the "user" specified for
32 the -maproot and -mapall exports(5) options may be in more than
36 sed(1) has learned about hex escapes (e.g. \x27) and will now do the
37 right thing with them, removing the need for printf magic or obnoxious
38 escaping in many scenarios.
40 r361238, r361798, r361799:
41 ZFS will now unconditionally reject read(2) of a directory with EISDIR.
42 Additionally, read(2) of a directory is now rejected with EISDIR by
43 default and may be re-enabled for non-ZFS filesystems that allow it with
44 the sysctl(8) MIB 'security.bsd.allow_read_dir'.
46 Aliases for grep to default to '-d skip' may be desired if commonly
47 non-recursively grepping a list that includes directories and the
48 possibility of EISDIR errors in stderr is not tolerable. Example
49 aliases, commented out, have been installed in /root/.cshrc and
53 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5).
54 exec.prepare runs before mounts, so can be used to populate new jails.
55 exec.release runs after unmounts, so can be used to remove ephemeral
58 r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936:
59 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5,
60 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from
61 the kernel open cryptographic framework (OCF).
64 Remove support for ARC4, Blowfish, Cast, DES, Triple DES,
65 MD5-HMAC, and Skipjack algorithms from /dev/crypto.
68 Remove support for DES, Triple DES, Blowfish, Cast, and
69 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC,
70 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4).
73 Remove support for Triple DES, Blowfish, and MD5 HMAC from
77 Remove support for DES, Triple DES, and RC4 from in-kernel GSS
84 init(8), service(8), and cron(8) will now adopt user/class environment
85 variables (excluding PATH, by default, which will be overwritten) by
86 default. Notably, environment variables for all cron jobs and rc
87 services can now be set via login.conf(5).
90 sparc64 has been removed from FreeBSD.
93 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
94 (RFC-8276) to the NFS client and server.
95 NFSv4.2 is comprised of several optional features that can be supported
96 in addition to NFSv4.1. This patch adds the following optional features:
97 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
99 - intra server file range copying via the copy_file_range(2) syscall
100 --> Avoiding data tranfer over the wire to/from the NFS client.
101 - lseek(SEEK_DATA/SEEK_HOLE)
102 - Extended attribute syscalls for "user" namespace attributes as defined
105 For the client, NFSv4.2 is only used if the mount command line option
106 minorversion=2 is specified.
107 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
108 and vfs.nfsd.server_max_minorversion4 have been added that allow
109 sysadmins to limit the minor versions of NFSv4 supported by the nfsd
111 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
115 armv5 support has been removed from FreeBSD.
118 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
121 sqlite3 is updated to sqlite3-3.30.1.
124 cron(8) now supports the -n (suppress mail on succesful run) and -q
125 (suppress logging of command execution) options in the crontab format.
126 See the crontab(5) manpage for details.
129 ntpd is no longer by default locked in memory. rlimit memlock 32
130 or rlimit memlock 0 can be used to restore this behaviour.
132 r351770,r352920,r352922,r352923:
133 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync,
134 and iflag=fullblock flags, compatible with illumos and GNU.
137 Add kernel-side support for in-kernel Transport Layer Security
138 (KTLS). KTLS permits using sendfile(2) over sockets using
142 WPA is updated from 2.8 to 2.9.
145 Add probes for lockmgr(9) to the lockstat DTrace provider, add
146 corresponding lockstat(1) events, and document the new probes in
150 Intel RST is a new 'feature' that remaps NVMe devices from
151 their normal location to part of the AHCI bar space. This
152 will eliminate the need to set the BIOS SATA setting from RST
153 to AHCI causing the nvme drive to be erased before FreeBSD
154 will see the nvme drive. FreeBSD will now be able to see the
155 nvme drive now in the default config.
158 Add a vop_stdioctl() call, so that file systems that do not support
159 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
160 The algorithm appears to be compatible with the POSIX draft and
161 the implementation in Linux for the case of a file system that
162 does not support holes. Prior to this patch, lseek(2) would reply
163 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
164 file systems that do not support holes.
165 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
166 any other cases, such as a ENOTTY return from vn_bmap_seekhole().
169 The fuse driver has been renamed to fusefs(5) and been substantially
170 rewritten. The new driver includes many bug fixes and performance
171 enhancements, as well as the following user-visible features:
172 * Optional kernel-side permissions checks (-o default_permissions)
173 * mknod(2), socket(2), and pipe(2) support
174 * server side locking with fcntl(2)
175 * FUSE operations are now interruptible when mounted with -o intr
176 * server side handling of UTIME_NOW during utimensat(2)
177 * mount options may be updated with "mount -u"
178 * fusefs file system may now be exported over NFS
179 * RLIMIT_FSIZE support
180 * support for fuse file systems using protocols as old as 7.4
182 FUSE file system developers should also take note of the following new
184 * The protocol level has been raised from 7.8 to 7.23
185 * kqueue support on /dev/fuse
186 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY
189 gnop(8) can now configure a delay to be applied to read and write
190 request delays. See the -d, -q and -x parameters.
193 Adds a Linux compatible copy_file_range(2) syscall.
196 libcap_random(3) has been removed. Applications can use native
197 APIs to get random data in capability mode.
200 Add support for using unmapped mbufs with sendfile(2).
203 nand(4) and related components have been removed.
206 The UEFI loader now supports HTTP boot.
209 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
210 guests to play to and record audio data from the host.
213 swapon(8) can now erase a swap device immediately before enabling it,
214 similar to newfs(8)'s -E option. This behaviour can be specified by
215 adding -E to swapon(8)'s command-line parameters, or by adding the
216 "trimonce" option to a swap device's /etc/fstab entry.
219 The following network drivers have been removed: bm(4), cs(4), de(4),
220 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
224 Wired page accounting has been split into kernel wirings and user
225 wirings (e.g., by mlock(2)). Kernel wirings no long count towards
226 the global limit, which is renamed to vm.max_user_wired. bhyve -S
227 allocates user-wired memory and is now subject to that limit.
