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 The aesni(4) and armv8crypto(4) devices are now included in
15 GENERIC on amd64, i386, and arm64.
18 Add support for enforcing W^X mapping policy for user
19 processes. The policy is not enforced by default but can be
20 enabled by setting the kern.elf32.allow_wx and
21 kern.elf64.allow_wx sysctls to 0. Individual binaries can be
22 exempted from the policy by elfctl(1) via the wxneeded
26 Add AES-XTS support to armv8crypto(4) providing accelerated
27 software support for the default GELI cipher on arm64 systems.
30 GDB 6.1.1 was removed. Users of crashinfo(8) should install the
31 gdb package or devel/gdb port.
34 The hme(4) driver was removed.
37 Fixes the case where gssd will not startup because /usr is a separate
38 local file system that is not yet mounted. It does not fix the case
39 where /usr is a separately mounted remote file system (such as NFS).
40 This latter case can be fixed by adding mountcritremote to the
41 REQUIRED line. Unfortunately doing so implies that all Kerberized
42 NFS mounts in /etc/fstab will need the "late" mount option.
43 This was not done, since the requirement for "late" would introduce
47 This commit added a new startup scripts variable called
48 nfsv4_server_only which uses the -R option on mountd added by r367026.
49 When nfsv4_server_only is set to "YES" in /etc/rc.conf, the NFS server
50 only handles NFSv4 and does not register with rpcbind. As such, rpcbind
51 does not need to be running. Useful for sites which consider rpcbind a
55 Kernel option ACPI_DMAR was renamed to IOMMU. amd64's IOMMU subsystem
56 was split out from amd64 DMAR support and is now generic, i.e., it can
57 be used by all architectures.
60 A series of commits ending with r364896 added NFS over TLS
61 to the kernel. This is believed to be compatible with
62 the Internet Draft titled "Towards Remote Procedure Call Encryption
63 By Default" (expected to soon become an RFC).
64 The mount_nfs(8) and exports(5) man pages describe the mount and
65 export option(s) related to NFS over TLS.
66 For NFS over TLS to work, the rpctlscd(8) { client } or rpctlssd(8)
67 { server } must be running on a kernel built with "options KERN_TLS"
68 on an architecture where PMAP_HAS_DMAP != 0.
71 Changes to one obscure devd event generated on resume need to
72 be documented. The old form will still be generated in 13, but not
76 Applications using regex(3), e.g. sed/grep, will no longer accept
77 redundant escapes for most ordinary characters.
80 SCTP support has been removed from GENERIC kernel configurations.
81 The SCTP stack is now built as sctp.ko and can be dynamically loaded.
84 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details.
87 The safexcel(4) crypto offload driver has been added.
90 nc(1) now implements SCTP mode, enabled by specifying the --sctp option.
93 A new implementation of bc and dc has been imported. It offers
94 better standards compliance, performance, localization and comes
95 with extensive test cases that are optionally installed.
96 Use WITHOUT_GH_BC=yes to build and install the world with the
97 previous version instead of the new one, if required.
100 struct export_args has changed so that the "user" specified for
101 the -maproot and -mapall exports(5) options may be in more than
105 sed(1) has learned about hex escapes (e.g. \x27) and will now do the
106 right thing with them, removing the need for printf magic or obnoxious
107 escaping in many scenarios.
109 r361238, r361798, r361799:
110 ZFS will now unconditionally reject read(2) of a directory with EISDIR.
111 Additionally, read(2) of a directory is now rejected with EISDIR by
112 default and may be re-enabled for non-ZFS filesystems that allow it with
113 the sysctl(8) MIB 'security.bsd.allow_read_dir'.
115 Aliases for grep to default to '-d skip' may be desired if commonly
116 non-recursively grepping a list that includes directories and the
117 possibility of EISDIR errors in stderr is not tolerable. Example
118 aliases, commented out, have been installed in /root/.cshrc and
122 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5).
123 exec.prepare runs before mounts, so can be used to populate new jails.
124 exec.release runs after unmounts, so can be used to remove ephemeral
127 r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936:
128 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5,
129 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from
130 the kernel open cryptographic framework (OCF).
133 Remove support for ARC4, Blowfish, Cast, DES, Triple DES,
134 MD5-HMAC, and Skipjack algorithms from /dev/crypto.
137 Remove support for DES, Triple DES, Blowfish, Cast, and
138 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC,
139 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4).
142 Remove support for Triple DES, Blowfish, and MD5 HMAC from
146 Remove support for DES, Triple DES, and RC4 from in-kernel GSS
153 init(8), service(8), and cron(8) will now adopt user/class environment
154 variables (excluding PATH, by default, which will be overwritten) by
155 default. Notably, environment variables for all cron jobs and rc
156 services can now be set via login.conf(5).
159 sparc64 has been removed from FreeBSD.
162 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
163 (RFC-8276) to the NFS client and server.
164 NFSv4.2 is comprised of several optional features that can be supported
165 in addition to NFSv4.1. This patch adds the following optional features:
166 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
168 - intra server file range copying via the copy_file_range(2) syscall
169 --> Avoiding data tranfer over the wire to/from the NFS client.
170 - lseek(SEEK_DATA/SEEK_HOLE)
171 - Extended attribute syscalls for "user" namespace attributes as defined
174 For the client, NFSv4.2 is only used if the mount command line option
175 minorversion=2 is specified.
176 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
177 and vfs.nfsd.server_max_minorversion4 have been added that allow
178 sysadmins to limit the minor versions of NFSv4 supported by the nfsd
180 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
184 armv5 support has been removed from FreeBSD.
187 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
190 sqlite3 is updated to sqlite3-3.30.1.
193 cron(8) now supports the -n (suppress mail on succesful run) and -q
194 (suppress logging of command execution) options in the crontab format.
195 See the crontab(5) manpage for details.
198 ntpd is no longer by default locked in memory. rlimit memlock 32
199 or rlimit memlock 0 can be used to restore this behaviour.
202 rc.subr(8) now honors ${name}_env in all rc(8) scripts. Previously,
203 environment variables set by a user via ${name}_env were ignored
204 if the service defined a custom *_cmd variable to control the behavior
205 of the run_rc_command function, e.g., start_cmd, instead of relying on
206 the variables like command and command_args,
208 r351770,r352920,r352922,r352923:
209 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync,
210 and iflag=fullblock flags, compatible with illumos and GNU.
213 Add kernel-side support for in-kernel Transport Layer Security
214 (KTLS). KTLS permits using sendfile(2) over sockets using
218 WPA is updated from 2.8 to 2.9.
221 Add probes for lockmgr(9) to the lockstat DTrace provider, add
222 corresponding lockstat(1) events, and document the new probes in
226 Intel RST is a new 'feature' that remaps NVMe devices from
227 their normal location to part of the AHCI bar space. This
228 will eliminate the need to set the BIOS SATA setting from RST
229 to AHCI causing the nvme drive to be erased before FreeBSD
230 will see the nvme drive. FreeBSD will now be able to see the
231 nvme drive now in the default config.
234 Add a vop_stdioctl() call, so that file systems that do not support
235 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
236 The algorithm appears to be compatible with the POSIX draft and
237 the implementation in Linux for the case of a file system that
238 does not support holes. Prior to this patch, lseek(2) would reply
239 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
240 file systems that do not support holes.
241 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
242 any other cases, such as a ENOTTY return from vn_bmap_seekhole().
245 The fuse driver has been renamed to fusefs(5) and been substantially
246 rewritten. The new driver includes many bug fixes and performance
247 enhancements, as well as the following user-visible features:
248 * Optional kernel-side permissions checks (-o default_permissions)
249 * mknod(2), socket(2), and pipe(2) support
250 * server side locking with fcntl(2)
251 * FUSE operations are now interruptible when mounted with -o intr
252 * server side handling of UTIME_NOW during utimensat(2)
253 * mount options may be updated with "mount -u"
254 * fusefs file system may now be exported over NFS
255 * RLIMIT_FSIZE support
256 * support for fuse file systems using protocols as old as 7.4
258 FUSE file system developers should also take note of the following new
260 * The protocol level has been raised from 7.8 to 7.23
261 * kqueue support on /dev/fuse
262 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY
265 gnop(8) can now configure a delay to be applied to read and write
266 request delays. See the -d, -q and -x parameters.
269 Adds a Linux compatible copy_file_range(2) syscall.
272 libcap_random(3) has been removed. Applications can use native
273 APIs to get random data in capability mode.
276 Add support for using unmapped mbufs with sendfile(2).
279 nand(4) and related components have been removed.
282 The UEFI loader now supports HTTP boot.
285 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
286 guests to play to and record audio data from the host.
289 swapon(8) can now erase a swap device immediately before enabling it,
290 similar to newfs(8)'s -E option. This behaviour can be specified by
291 adding -E to swapon(8)'s command-line parameters, or by adding the
292 "trimonce" option to a swap device's /etc/fstab entry.
295 The following network drivers have been removed: bm(4), cs(4), de(4),
296 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
300 Wired page accounting has been split into kernel wirings and user
301 wirings (e.g., by mlock(2)). Kernel wirings no long count towards
302 the global limit, which is renamed to vm.max_user_wired. bhyve -S
303 allocates user-wired memory and is now subject to that limit.
