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