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 Kernel option ACPI_DMAR was renamed to IOMMU. amd64's IOMMU subsystem
15 was split out from amd64 DMAR support and is now generic, i.e., it can
16 be used by all architectures.
19 A series of commits ending with r364896 added NFS over TLS
20 to the kernel. This is believed to be compatible with
21 the Internet Draft titled "Towards Remote Procedure Call Encryption
22 By Default" (expected to soon become an RFC).
23 The mount_nfs(8) and exports(5) man pages describe the mount and
24 export option(s) related to NFS over TLS.
25 For NFS over TLS to work, the rpctlscd(8) { client } or rpctlssd(8)
26 { server } must be running on a kernel built with "options KERN_TLS"
27 on an architecture where PMAP_HAS_DMAP != 0.
30 Changes to one obscure devd event generated on resume need to
31 be documented. The old form will still be generated in 13, but not
35 Applications using regex(3), e.g. sed/grep, will no longer accept
36 redundant escapes for most ordinary characters.
39 SCTP support has been removed from GENERIC kernel configurations.
40 The SCTP stack is now built as sctp.ko and can be dynamically loaded.
43 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details.
46 The safexcel(4) crypto offload driver has been added.
49 nc(1) now implements SCTP mode, enabled by specifying the --sctp option.
52 A new implementation of bc and dc has been imported. It offers
53 better standards compliance, performance, localization and comes
54 with extensive test cases that are optionally installed.
55 Use WITHOUT_GH_BC=yes to build and install the world with the
56 previous version instead of the new one, if required.
59 struct export_args has changed so that the "user" specified for
60 the -maproot and -mapall exports(5) options may be in more than
64 sed(1) has learned about hex escapes (e.g. \x27) and will now do the
65 right thing with them, removing the need for printf magic or obnoxious
66 escaping in many scenarios.
68 r361238, r361798, r361799:
69 ZFS will now unconditionally reject read(2) of a directory with EISDIR.
70 Additionally, read(2) of a directory is now rejected with EISDIR by
71 default and may be re-enabled for non-ZFS filesystems that allow it with
72 the sysctl(8) MIB 'security.bsd.allow_read_dir'.
74 Aliases for grep to default to '-d skip' may be desired if commonly
75 non-recursively grepping a list that includes directories and the
76 possibility of EISDIR errors in stderr is not tolerable. Example
77 aliases, commented out, have been installed in /root/.cshrc and
81 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5).
82 exec.prepare runs before mounts, so can be used to populate new jails.
83 exec.release runs after unmounts, so can be used to remove ephemeral
86 r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936:
87 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5,
88 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from
89 the kernel open cryptographic framework (OCF).
92 Remove support for ARC4, Blowfish, Cast, DES, Triple DES,
93 MD5-HMAC, and Skipjack algorithms from /dev/crypto.
96 Remove support for DES, Triple DES, Blowfish, Cast, and
97 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC,
98 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4).
101 Remove support for Triple DES, Blowfish, and MD5 HMAC from
105 Remove support for DES, Triple DES, and RC4 from in-kernel GSS
112 init(8), service(8), and cron(8) will now adopt user/class environment
113 variables (excluding PATH, by default, which will be overwritten) by
114 default. Notably, environment variables for all cron jobs and rc
115 services can now be set via login.conf(5).
118 sparc64 has been removed from FreeBSD.
121 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
122 (RFC-8276) to the NFS client and server.
123 NFSv4.2 is comprised of several optional features that can be supported
124 in addition to NFSv4.1. This patch adds the following optional features:
125 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
127 - intra server file range copying via the copy_file_range(2) syscall
128 --> Avoiding data tranfer over the wire to/from the NFS client.
129 - lseek(SEEK_DATA/SEEK_HOLE)
130 - Extended attribute syscalls for "user" namespace attributes as defined
133 For the client, NFSv4.2 is only used if the mount command line option
134 minorversion=2 is specified.
135 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
136 and vfs.nfsd.server_max_minorversion4 have been added that allow
137 sysadmins to limit the minor versions of NFSv4 supported by the nfsd
139 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
143 armv5 support has been removed from FreeBSD.
146 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
149 sqlite3 is updated to sqlite3-3.30.1.
152 cron(8) now supports the -n (suppress mail on succesful run) and -q
153 (suppress logging of command execution) options in the crontab format.
154 See the crontab(5) manpage for details.
157 ntpd is no longer by default locked in memory. rlimit memlock 32
158 or rlimit memlock 0 can be used to restore this behaviour.
160 r351770,r352920,r352922,r352923:
161 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync,
162 and iflag=fullblock flags, compatible with illumos and GNU.
165 Add kernel-side support for in-kernel Transport Layer Security
166 (KTLS). KTLS permits using sendfile(2) over sockets using
170 WPA is updated from 2.8 to 2.9.
173 Add probes for lockmgr(9) to the lockstat DTrace provider, add
174 corresponding lockstat(1) events, and document the new probes in
178 Intel RST is a new 'feature' that remaps NVMe devices from
179 their normal location to part of the AHCI bar space. This
180 will eliminate the need to set the BIOS SATA setting from RST
181 to AHCI causing the nvme drive to be erased before FreeBSD
182 will see the nvme drive. FreeBSD will now be able to see the
183 nvme drive now in the default config.
186 Add a vop_stdioctl() call, so that file systems that do not support
187 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
188 The algorithm appears to be compatible with the POSIX draft and
189 the implementation in Linux for the case of a file system that
190 does not support holes. Prior to this patch, lseek(2) would reply
191 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
192 file systems that do not support holes.
193 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
194 any other cases, such as a ENOTTY return from vn_bmap_seekhole().
197 The fuse driver has been renamed to fusefs(5) and been substantially
198 rewritten. The new driver includes many bug fixes and performance
199 enhancements, as well as the following user-visible features:
200 * Optional kernel-side permissions checks (-o default_permissions)
201 * mknod(2), socket(2), and pipe(2) support
202 * server side locking with fcntl(2)
203 * FUSE operations are now interruptible when mounted with -o intr
204 * server side handling of UTIME_NOW during utimensat(2)
205 * mount options may be updated with "mount -u"
206 * fusefs file system may now be exported over NFS
207 * RLIMIT_FSIZE support
208 * support for fuse file systems using protocols as old as 7.4
210 FUSE file system developers should also take note of the following new
212 * The protocol level has been raised from 7.8 to 7.23
213 * kqueue support on /dev/fuse
214 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY
217 gnop(8) can now configure a delay to be applied to read and write
218 request delays. See the -d, -q and -x parameters.
221 Adds a Linux compatible copy_file_range(2) syscall.
224 libcap_random(3) has been removed. Applications can use native
225 APIs to get random data in capability mode.
228 Add support for using unmapped mbufs with sendfile(2).
231 nand(4) and related components have been removed.
234 The UEFI loader now supports HTTP boot.
237 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
238 guests to play to and record audio data from the host.
241 swapon(8) can now erase a swap device immediately before enabling it,
242 similar to newfs(8)'s -E option. This behaviour can be specified by
243 adding -E to swapon(8)'s command-line parameters, or by adding the
244 "trimonce" option to a swap device's /etc/fstab entry.
247 The following network drivers have been removed: bm(4), cs(4), de(4),
248 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
252 Wired page accounting has been split into kernel wirings and user
253 wirings (e.g., by mlock(2)). Kernel wirings no long count towards
254 the global limit, which is renamed to vm.max_user_wired. bhyve -S
255 allocates user-wired memory and is now subject to that limit.
