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.
13 33ff39796ffe,8719e8a951b7:
14 A new rc(8) service script zfskeys allows for automatic decryption
15 of ZFS datasets encrypted with ZFS native encryption during boot.
16 See the rc.conf(5) manual page for more information.
18 b7a2cf0d9102 - eae02d959363:
19 Upgrade bhyve's emulation to version 1.4 of the NVMe specification
21 0a6760a1de32, 3f3676a71266, 580c04df4db6:
25 Add support for the HiFive Unmatched RISC-V board.
28 Add a sysctl called vfs.nfsd.srvmaxio that can be used to
29 increase the NFS server's maximum I/O size from 128Kbytes
30 to any power of 2 up to 1Mbyte. It can only be set when
31 the nfsd threads are not running and will normally require
32 an increase in kern.ipc.maxsockbuf to at least the value
33 recommended by the console log message generated when
34 setting vfs.nfsd.srvmaxio is first attempted.
37 Add a new NFSv4.1/4.2 mount option "nconnect" that can
38 be used to specify the number of TCP connections that
39 will be used for the mount, up to a maximum of 16.
40 The first (default) TCP connection will be used for
41 all RPCs that consist of small RPC messages.
42 The RPCs that can consist of large RPC messages
43 (Read/Readdir/ReaddirPlus/Write) will be sent on the
44 additional TCP connections in a round robin fashion.
45 If either the NFS client or NFS server have multiple
46 network interfaces aggregated together or a network
47 interface that uses multiple queues, this can increase
48 NFS performance for the mount.
51 One True Awk has been updated to the latest from upstream
52 (20210215). All the FreeBSD patches, but one, have now been
53 either up streamed or discarded. Notable changes include:
54 o Locale is no longer used for ranges
56 o Better compatibility with gawk and mawk
58 The one FreeBSD change, likely to be removed in FreeBSD 14, is that
59 we still allow hex numbers, prefixed with 0x, to be parsed and
60 interpreted as hex numbers while all other awks (including one
61 true awk now) interpret them as 0 in line with awk's historic
65 Change the default minor version used for an NFSv4 mount
66 to the highest minor version supported by the NFSv4 server.
67 This default can be overridden by using the "minorversion"
70 2c76eebca71b, 59f6f5e23c1a:
71 Add two daemons rpc.tlsclntd(8) and rpc.tlsservd(8) that provide
72 support for NFS-over-TLS as described in the Internet Draft titled
73 "Towards Remote Procedure Call Encryption By Default".
74 These daemons are only built when WITH_OPENSSL_KTLS is specified
75 and are only tested on amd64 at this time.
76 They use KTLS to encrypt/decrypt all NFS RPC message traffic, plus
77 optional verification of machine identity via X.509 certificates.
80 Add AES-GCM support to armv8crypto(4) providing accelerated
81 support for KTLS, IPsec, and other crypto API consumers.
84 The aesni(4) and armv8crypto(4) devices are now included in
85 GENERIC on amd64, i386, and arm64.
88 Add support for enforcing W^X mapping policy for user
89 processes. The policy is not enforced by default but can be
90 enabled by setting the kern.elf32.allow_wx and
91 kern.elf64.allow_wx sysctls to 0. Individual binaries can be
92 exempted from the policy by elfctl(1) via the wxneeded
96 Add AES-XTS support to armv8crypto(4) providing accelerated
97 software support for the default GELI cipher on arm64 systems.
100 Add aio_writev(2) and aio_readv(2), vectored analogues of aio_write(2)
104 The fusefs(5) protocol has been updated to 7.28. Support for
105 FUSE_COPY_FILE_RANGE and FUSE_LSEEK is added.
108 GDB 6.1.1 was removed. Users of crashinfo(8) should install the
109 gdb package or devel/gdb port.
112 The hme(4) driver was removed.
115 Fixes the case where gssd will not startup because /usr is a separate
116 local file system that is not yet mounted. It does not fix the case
117 where /usr is a separately mounted remote file system (such as NFS).
118 This latter case can be fixed by adding mountcritremote to the
119 REQUIRED line. Unfortunately doing so implies that all Kerberized
120 NFS mounts in /etc/fstab will need the "late" mount option.
121 This was not done, since the requirement for "late" would introduce
125 This commit added a new startup scripts variable called
126 nfsv4_server_only which uses the -R option on mountd added by r367026.
127 When nfsv4_server_only is set to "YES" in /etc/rc.conf, the NFS server
128 only handles NFSv4 and does not register with rpcbind. As such, rpcbind
129 does not need to be running. Useful for sites which consider rpcbind a
133 Kernel option ACPI_DMAR was renamed to IOMMU. amd64's IOMMU subsystem
134 was split out from amd64 DMAR support and is now generic, i.e., it can
135 be used by all architectures.
138 A series of commits ending with r364896 added NFS over TLS
139 to the kernel. This is believed to be compatible with
140 the Internet Draft titled "Towards Remote Procedure Call Encryption
141 By Default" (expected to soon become an RFC).
142 The mount_nfs(8) and exports(5) man pages describe the mount and
143 export option(s) related to NFS over TLS.
144 For NFS over TLS to work, the rpctlscd(8) { client } or rpctlssd(8)
145 { server } must be running on a kernel built with "options KERN_TLS"
146 on an architecture where PMAP_HAS_DMAP != 0.
149 Changes to one obscure devd event generated on resume need to
150 be documented. The old form will still be generated in 13, but not
154 Applications using regex(3), e.g. sed/grep, will no longer accept
155 redundant escapes for most ordinary characters.
158 SCTP support has been removed from GENERIC kernel configurations.
159 The SCTP stack is now built as sctp.ko and can be dynamically loaded.
162 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details.
165 The safexcel(4) crypto offload driver has been added.
168 nc(1) now implements SCTP mode, enabled by specifying the --sctp option.
171 A new implementation of bc and dc has been imported. It offers
172 better standards compliance, performance, localization and comes
173 with extensive test cases that are optionally installed.
174 Use WITHOUT_GH_BC=yes to build and install the world with the
175 previous version instead of the new one, if required.
178 struct export_args has changed so that the "user" specified for
179 the -maproot and -mapall exports(5) options may be in more than
183 sed(1) has learned about hex escapes (e.g. \x27) and will now do the
184 right thing with them, removing the need for printf magic or obnoxious
185 escaping in many scenarios.
187 r361238, r361798, r361799:
188 ZFS will now unconditionally reject read(2) of a directory with EISDIR.
189 Additionally, read(2) of a directory is now rejected with EISDIR by
190 default and may be re-enabled for non-ZFS filesystems that allow it with
191 the sysctl(8) MIB 'security.bsd.allow_read_dir'.
193 Aliases for grep to default to '-d skip' may be desired if commonly
194 non-recursively grepping a list that includes directories and the
195 possibility of EISDIR errors in stderr is not tolerable. Example
196 aliases, commented out, have been installed in /root/.cshrc and
200 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5).
201 exec.prepare runs before mounts, so can be used to populate new jails.
202 exec.release runs after unmounts, so can be used to remove ephemeral
205 r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936:
206 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5,
207 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from
208 the kernel open cryptographic framework (OCF).
211 Remove support for ARC4, Blowfish, Cast, DES, Triple DES,
212 MD5-HMAC, and Skipjack algorithms from /dev/crypto.
215 Remove support for DES, Triple DES, Blowfish, Cast, and
216 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC,
217 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4).
220 Remove support for Triple DES, Blowfish, and MD5 HMAC from
224 Remove support for DES, Triple DES, and RC4 from in-kernel GSS
231 init(8), service(8), and cron(8) will now adopt user/class environment
232 variables (excluding PATH, by default, which will be overwritten) by
233 default. Notably, environment variables for all cron jobs and rc
234 services can now be set via login.conf(5).
237 sparc64 has been removed from FreeBSD.
240 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
241 (RFC-8276) to the NFS client and server.
242 NFSv4.2 is comprised of several optional features that can be supported
243 in addition to NFSv4.1. This patch adds the following optional features:
244 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
246 - intra server file range copying via the copy_file_range(2) syscall
247 --> Avoiding data tranfer over the wire to/from the NFS client.
248 - lseek(SEEK_DATA/SEEK_HOLE)
249 - Extended attribute syscalls for "user" namespace attributes as defined
252 For the client, NFSv4.2 is only used if the mount command line option
253 minorversion=2 is specified.
254 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
255 and vfs.nfsd.server_max_minorversion4 have been added that allow
256 sysadmins to limit the minor versions of NFSv4 supported by the nfsd
258 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
262 armv5 support has been removed from FreeBSD.
265 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
268 sqlite3 is updated to sqlite3-3.30.1.
271 cron(8) now supports the -n (suppress mail on succesful run) and -q
272 (suppress logging of command execution) options in the crontab format.
273 See the crontab(5) manpage for details.
276 ntpd is no longer by default locked in memory. rlimit memlock 32
277 or rlimit memlock 0 can be used to restore this behaviour.
280 rc.subr(8) now honors ${name}_env in all rc(8) scripts. Previously,
281 environment variables set by a user via ${name}_env were ignored
282 if the service defined a custom *_cmd variable to control the behavior
283 of the run_rc_command function, e.g., start_cmd, instead of relying on
284 the variables like command and command_args,
286 r351770,r352920,r352922,r352923:
287 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync,
288 and iflag=fullblock flags, compatible with illumos and GNU.
291 Add kernel-side support for in-kernel Transport Layer Security
292 (KTLS). KTLS permits using sendfile(2) over sockets using
296 WPA is updated from 2.8 to 2.9.
299 Add probes for lockmgr(9) to the lockstat DTrace provider, add
300 corresponding lockstat(1) events, and document the new probes in
304 Intel RST is a new 'feature' that remaps NVMe devices from
305 their normal location to part of the AHCI bar space. This
306 will eliminate the need to set the BIOS SATA setting from RST
307 to AHCI causing the nvme drive to be erased before FreeBSD
308 will see the nvme drive. FreeBSD will now be able to see the
309 nvme drive now in the default config.
312 Add a vop_stdioctl() call, so that file systems that do not support
313 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
314 The algorithm appears to be compatible with the POSIX draft and
315 the implementation in Linux for the case of a file system that
316 does not support holes. Prior to this patch, lseek(2) would reply
317 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
318 file systems that do not support holes.
319 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
320 any other cases, such as a ENOTTY return from vn_bmap_seekhole().
323 The fuse driver has been renamed to fusefs(5) and been substantially
324 rewritten. The new driver includes many bug fixes and performance
325 enhancements, as well as the following user-visible features:
326 * Optional kernel-side permissions checks (-o default_permissions)
327 * mknod(2), socket(2), and pipe(2) support
328 * server side locking with fcntl(2)
329 * FUSE operations are now interruptible when mounted with -o intr
330 * server side handling of UTIME_NOW during utimensat(2)
331 * mount options may be updated with "mount -u"
332 * fusefs file system may now be exported over NFS
333 * RLIMIT_FSIZE support
334 * support for fuse file systems using protocols as old as 7.4
336 FUSE file system developers should also take note of the following new
338 * The protocol level has been raised from 7.8 to 7.23
339 * kqueue support on /dev/fuse
340 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY
343 gnop(8) can now configure a delay to be applied to read and write
344 request delays. See the -d, -q and -x parameters.
347 Adds a Linux compatible copy_file_range(2) syscall.
350 libcap_random(3) has been removed. Applications can use native
351 APIs to get random data in capability mode.
354 Add support for using unmapped mbufs with sendfile(2).
357 nand(4) and related components have been removed.
360 The UEFI loader now supports HTTP boot.
363 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
364 guests to play to and record audio data from the host.
367 swapon(8) can now erase a swap device immediately before enabling it,
368 similar to newfs(8)'s -E option. This behaviour can be specified by
369 adding -E to swapon(8)'s command-line parameters, or by adding the
370 "trimonce" option to a swap device's /etc/fstab entry.
373 The following network drivers have been removed: bm(4), cs(4), de(4),
374 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
378 Wired page accounting has been split into kernel wirings and user
379 wirings (e.g., by mlock(2)). Kernel wirings no long count towards
380 the global limit, which is renamed to vm.max_user_wired. bhyve -S
381 allocates user-wired memory and is now subject to that limit.
