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