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 Changes to one obscure devd event generated on resume need to
15 be documented. The old form will still be generated in 13, but not
19 Applications using regex(3), e.g. sed/grep, will no longer accept
20 redundant escapes for most ordinary characters.
23 SCTP support has been removed from GENERIC kernel configurations.
24 The SCTP stack is now built as sctp.ko and can be dynamically loaded.
27 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details.
30 The safexcel(4) crypto offload driver has been added.
33 nc(1) now implements SCTP mode, enabled by specifying the --sctp option.
36 A new implementation of bc and dc has been imported. It offers
37 better standards compliance, performance, localization and comes
38 with extensive test cases that are optionally installed.
39 Use WITHOUT_GH_BC=yes to build and install the world with the
40 previous version instead of the new one, if required.
43 struct export_args has changed so that the "user" specified for
44 the -maproot and -mapall exports(5) options may be in more than
48 sed(1) has learned about hex escapes (e.g. \x27) and will now do the
49 right thing with them, removing the need for printf magic or obnoxious
50 escaping in many scenarios.
52 r361238, r361798, r361799:
53 ZFS will now unconditionally reject read(2) of a directory with EISDIR.
54 Additionally, read(2) of a directory is now rejected with EISDIR by
55 default and may be re-enabled for non-ZFS filesystems that allow it with
56 the sysctl(8) MIB 'security.bsd.allow_read_dir'.
58 Aliases for grep to default to '-d skip' may be desired if commonly
59 non-recursively grepping a list that includes directories and the
60 possibility of EISDIR errors in stderr is not tolerable. Example
61 aliases, commented out, have been installed in /root/.cshrc and
65 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5).
66 exec.prepare runs before mounts, so can be used to populate new jails.
67 exec.release runs after unmounts, so can be used to remove ephemeral
70 r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936:
71 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5,
72 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from
73 the kernel open cryptographic framework (OCF).
76 Remove support for ARC4, Blowfish, Cast, DES, Triple DES,
77 MD5-HMAC, and Skipjack algorithms from /dev/crypto.
80 Remove support for DES, Triple DES, Blowfish, Cast, and
81 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC,
82 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4).
85 Remove support for Triple DES, Blowfish, and MD5 HMAC from
89 Remove support for DES, Triple DES, and RC4 from in-kernel GSS
96 init(8), service(8), and cron(8) will now adopt user/class environment
97 variables (excluding PATH, by default, which will be overwritten) by
98 default. Notably, environment variables for all cron jobs and rc
99 services can now be set via login.conf(5).
102 sparc64 has been removed from FreeBSD.
105 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
106 (RFC-8276) to the NFS client and server.
107 NFSv4.2 is comprised of several optional features that can be supported
108 in addition to NFSv4.1. This patch adds the following optional features:
109 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
111 - intra server file range copying via the copy_file_range(2) syscall
112 --> Avoiding data tranfer over the wire to/from the NFS client.
113 - lseek(SEEK_DATA/SEEK_HOLE)
114 - Extended attribute syscalls for "user" namespace attributes as defined
117 For the client, NFSv4.2 is only used if the mount command line option
118 minorversion=2 is specified.
119 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
120 and vfs.nfsd.server_max_minorversion4 have been added that allow
121 sysadmins to limit the minor versions of NFSv4 supported by the nfsd
123 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
127 armv5 support has been removed from FreeBSD.
130 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
133 sqlite3 is updated to sqlite3-3.30.1.
136 cron(8) now supports the -n (suppress mail on succesful run) and -q
137 (suppress logging of command execution) options in the crontab format.
138 See the crontab(5) manpage for details.
141 ntpd is no longer by default locked in memory. rlimit memlock 32
142 or rlimit memlock 0 can be used to restore this behaviour.
144 r351770,r352920,r352922,r352923:
145 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync,
146 and iflag=fullblock flags, compatible with illumos and GNU.
149 Add kernel-side support for in-kernel Transport Layer Security
150 (KTLS). KTLS permits using sendfile(2) over sockets using
154 WPA is updated from 2.8 to 2.9.
157 Add probes for lockmgr(9) to the lockstat DTrace provider, add
158 corresponding lockstat(1) events, and document the new probes in
162 Intel RST is a new 'feature' that remaps NVMe devices from
163 their normal location to part of the AHCI bar space. This
164 will eliminate the need to set the BIOS SATA setting from RST
165 to AHCI causing the nvme drive to be erased before FreeBSD
166 will see the nvme drive. FreeBSD will now be able to see the
167 nvme drive now in the default config.
170 Add a vop_stdioctl() call, so that file systems that do not support
171 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
172 The algorithm appears to be compatible with the POSIX draft and
173 the implementation in Linux for the case of a file system that
174 does not support holes. Prior to this patch, lseek(2) would reply
175 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
176 file systems that do not support holes.
177 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
178 any other cases, such as a ENOTTY return from vn_bmap_seekhole().
181 The fuse driver has been renamed to fusefs(5) and been substantially
182 rewritten. The new driver includes many bug fixes and performance
183 enhancements, as well as the following user-visible features:
184 * Optional kernel-side permissions checks (-o default_permissions)
185 * mknod(2), socket(2), and pipe(2) support
186 * server side locking with fcntl(2)
187 * FUSE operations are now interruptible when mounted with -o intr
188 * server side handling of UTIME_NOW during utimensat(2)
189 * mount options may be updated with "mount -u"
190 * fusefs file system may now be exported over NFS
191 * RLIMIT_FSIZE support
192 * support for fuse file systems using protocols as old as 7.4
194 FUSE file system developers should also take note of the following new
196 * The protocol level has been raised from 7.8 to 7.23
197 * kqueue support on /dev/fuse
198 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY
201 gnop(8) can now configure a delay to be applied to read and write
202 request delays. See the -d, -q and -x parameters.
205 Adds a Linux compatible copy_file_range(2) syscall.
208 libcap_random(3) has been removed. Applications can use native
209 APIs to get random data in capability mode.
212 Add support for using unmapped mbufs with sendfile(2).
215 nand(4) and related components have been removed.
218 The UEFI loader now supports HTTP boot.
221 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
222 guests to play to and record audio data from the host.
225 swapon(8) can now erase a swap device immediately before enabling it,
226 similar to newfs(8)'s -E option. This behaviour can be specified by
227 adding -E to swapon(8)'s command-line parameters, or by adding the
228 "trimonce" option to a swap device's /etc/fstab entry.
231 The following network drivers have been removed: bm(4), cs(4), de(4),
232 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
236 Wired page accounting has been split into kernel wirings and user
237 wirings (e.g., by mlock(2)). Kernel wirings no long count towards
238 the global limit, which is renamed to vm.max_user_wired. bhyve -S
239 allocates user-wired memory and is now subject to that limit.
