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 Add AES-GCM support to armv8crypto(4) providing accelerated
15 support for KTLS, IPsec, and other crypto API consumers.
18 The aesni(4) and armv8crypto(4) devices are now included in
19 GENERIC on amd64, i386, and arm64.
22 Add support for enforcing W^X mapping policy for user
23 processes. The policy is not enforced by default but can be
24 enabled by setting the kern.elf32.allow_wx and
25 kern.elf64.allow_wx sysctls to 0. Individual binaries can be
26 exempted from the policy by elfctl(1) via the wxneeded
30 Add AES-XTS support to armv8crypto(4) providing accelerated
31 software support for the default GELI cipher on arm64 systems.
34 GDB 6.1.1 was removed. Users of crashinfo(8) should install the
35 gdb package or devel/gdb port.
38 The hme(4) driver was removed.
41 Fixes the case where gssd will not startup because /usr is a separate
42 local file system that is not yet mounted. It does not fix the case
43 where /usr is a separately mounted remote file system (such as NFS).
44 This latter case can be fixed by adding mountcritremote to the
45 REQUIRED line. Unfortunately doing so implies that all Kerberized
46 NFS mounts in /etc/fstab will need the "late" mount option.
47 This was not done, since the requirement for "late" would introduce
51 This commit added a new startup scripts variable called
52 nfsv4_server_only which uses the -R option on mountd added by r367026.
53 When nfsv4_server_only is set to "YES" in /etc/rc.conf, the NFS server
54 only handles NFSv4 and does not register with rpcbind. As such, rpcbind
55 does not need to be running. Useful for sites which consider rpcbind a
59 Kernel option ACPI_DMAR was renamed to IOMMU. amd64's IOMMU subsystem
60 was split out from amd64 DMAR support and is now generic, i.e., it can
61 be used by all architectures.
64 A series of commits ending with r364896 added NFS over TLS
65 to the kernel. This is believed to be compatible with
66 the Internet Draft titled "Towards Remote Procedure Call Encryption
67 By Default" (expected to soon become an RFC).
68 The mount_nfs(8) and exports(5) man pages describe the mount and
69 export option(s) related to NFS over TLS.
70 For NFS over TLS to work, the rpctlscd(8) { client } or rpctlssd(8)
71 { server } must be running on a kernel built with "options KERN_TLS"
72 on an architecture where PMAP_HAS_DMAP != 0.
75 Changes to one obscure devd event generated on resume need to
76 be documented. The old form will still be generated in 13, but not
80 Applications using regex(3), e.g. sed/grep, will no longer accept
81 redundant escapes for most ordinary characters.
84 SCTP support has been removed from GENERIC kernel configurations.
85 The SCTP stack is now built as sctp.ko and can be dynamically loaded.
88 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details.
91 The safexcel(4) crypto offload driver has been added.
94 nc(1) now implements SCTP mode, enabled by specifying the --sctp option.
97 A new implementation of bc and dc has been imported. It offers
98 better standards compliance, performance, localization and comes
99 with extensive test cases that are optionally installed.
100 Use WITHOUT_GH_BC=yes to build and install the world with the
101 previous version instead of the new one, if required.
104 struct export_args has changed so that the "user" specified for
105 the -maproot and -mapall exports(5) options may be in more than
109 sed(1) has learned about hex escapes (e.g. \x27) and will now do the
110 right thing with them, removing the need for printf magic or obnoxious
111 escaping in many scenarios.
113 r361238, r361798, r361799:
114 ZFS will now unconditionally reject read(2) of a directory with EISDIR.
115 Additionally, read(2) of a directory is now rejected with EISDIR by
116 default and may be re-enabled for non-ZFS filesystems that allow it with
117 the sysctl(8) MIB 'security.bsd.allow_read_dir'.
119 Aliases for grep to default to '-d skip' may be desired if commonly
120 non-recursively grepping a list that includes directories and the
121 possibility of EISDIR errors in stderr is not tolerable. Example
122 aliases, commented out, have been installed in /root/.cshrc and
126 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5).
127 exec.prepare runs before mounts, so can be used to populate new jails.
128 exec.release runs after unmounts, so can be used to remove ephemeral
131 r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936:
132 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5,
133 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from
134 the kernel open cryptographic framework (OCF).
137 Remove support for ARC4, Blowfish, Cast, DES, Triple DES,
138 MD5-HMAC, and Skipjack algorithms from /dev/crypto.
141 Remove support for DES, Triple DES, Blowfish, Cast, and
142 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC,
143 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4).
146 Remove support for Triple DES, Blowfish, and MD5 HMAC from
150 Remove support for DES, Triple DES, and RC4 from in-kernel GSS
157 init(8), service(8), and cron(8) will now adopt user/class environment
158 variables (excluding PATH, by default, which will be overwritten) by
159 default. Notably, environment variables for all cron jobs and rc
160 services can now be set via login.conf(5).
163 sparc64 has been removed from FreeBSD.
166 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
167 (RFC-8276) to the NFS client and server.
168 NFSv4.2 is comprised of several optional features that can be supported
169 in addition to NFSv4.1. This patch adds the following optional features:
170 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
172 - intra server file range copying via the copy_file_range(2) syscall
173 --> Avoiding data tranfer over the wire to/from the NFS client.
174 - lseek(SEEK_DATA/SEEK_HOLE)
175 - Extended attribute syscalls for "user" namespace attributes as defined
178 For the client, NFSv4.2 is only used if the mount command line option
179 minorversion=2 is specified.
180 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
181 and vfs.nfsd.server_max_minorversion4 have been added that allow
182 sysadmins to limit the minor versions of NFSv4 supported by the nfsd
184 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
188 armv5 support has been removed from FreeBSD.
191 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
194 sqlite3 is updated to sqlite3-3.30.1.
197 cron(8) now supports the -n (suppress mail on succesful run) and -q
198 (suppress logging of command execution) options in the crontab format.
199 See the crontab(5) manpage for details.
202 ntpd is no longer by default locked in memory. rlimit memlock 32
203 or rlimit memlock 0 can be used to restore this behaviour.
206 rc.subr(8) now honors ${name}_env in all rc(8) scripts. Previously,
207 environment variables set by a user via ${name}_env were ignored
208 if the service defined a custom *_cmd variable to control the behavior
209 of the run_rc_command function, e.g., start_cmd, instead of relying on
210 the variables like command and command_args,
212 r351770,r352920,r352922,r352923:
213 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync,
214 and iflag=fullblock flags, compatible with illumos and GNU.
217 Add kernel-side support for in-kernel Transport Layer Security
218 (KTLS). KTLS permits using sendfile(2) over sockets using
222 WPA is updated from 2.8 to 2.9.
225 Add probes for lockmgr(9) to the lockstat DTrace provider, add
226 corresponding lockstat(1) events, and document the new probes in
230 Intel RST is a new 'feature' that remaps NVMe devices from
231 their normal location to part of the AHCI bar space. This
232 will eliminate the need to set the BIOS SATA setting from RST
233 to AHCI causing the nvme drive to be erased before FreeBSD
234 will see the nvme drive. FreeBSD will now be able to see the
235 nvme drive now in the default config.
238 Add a vop_stdioctl() call, so that file systems that do not support
239 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
240 The algorithm appears to be compatible with the POSIX draft and
241 the implementation in Linux for the case of a file system that
242 does not support holes. Prior to this patch, lseek(2) would reply
243 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
244 file systems that do not support holes.
245 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
246 any other cases, such as a ENOTTY return from vn_bmap_seekhole().
249 The fuse driver has been renamed to fusefs(5) and been substantially
250 rewritten. The new driver includes many bug fixes and performance
251 enhancements, as well as the following user-visible features:
252 * Optional kernel-side permissions checks (-o default_permissions)
253 * mknod(2), socket(2), and pipe(2) support
254 * server side locking with fcntl(2)
255 * FUSE operations are now interruptible when mounted with -o intr
256 * server side handling of UTIME_NOW during utimensat(2)
257 * mount options may be updated with "mount -u"
258 * fusefs file system may now be exported over NFS
259 * RLIMIT_FSIZE support
260 * support for fuse file systems using protocols as old as 7.4
262 FUSE file system developers should also take note of the following new
264 * The protocol level has been raised from 7.8 to 7.23
265 * kqueue support on /dev/fuse
266 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY
269 gnop(8) can now configure a delay to be applied to read and write
270 request delays. See the -d, -q and -x parameters.
273 Adds a Linux compatible copy_file_range(2) syscall.
276 libcap_random(3) has been removed. Applications can use native
277 APIs to get random data in capability mode.
280 Add support for using unmapped mbufs with sendfile(2).
283 nand(4) and related components have been removed.
286 The UEFI loader now supports HTTP boot.
289 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
290 guests to play to and record audio data from the host.
293 swapon(8) can now erase a swap device immediately before enabling it,
294 similar to newfs(8)'s -E option. This behaviour can be specified by
295 adding -E to swapon(8)'s command-line parameters, or by adding the
296 "trimonce" option to a swap device's /etc/fstab entry.
299 The following network drivers have been removed: bm(4), cs(4), de(4),
300 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
304 Wired page accounting has been split into kernel wirings and user
305 wirings (e.g., by mlock(2)). Kernel wirings no long count towards
306 the global limit, which is renamed to vm.max_user_wired. bhyve -S
307 allocates user-wired memory and is now subject to that limit.
