13 2c76eebca71b, 59f6f5e23c1a:
14 Add two daemons rpc.tlsclntd(8) and rpc.tlsservd(8) that provide
15 support for NFS-over-TLS as described in the Internet Draft titled
16 "Towards Remote Procedure Call Encryption By Default".
17 These daemons are only built when WITH_OPENSSL_KTLS is specified
18 and are only tested on amd64 at this time.
19 They use KTLS to encrypt/decrypt all NFS RPC message traffic, plus
20 optional verification of machine identity via X.509 certificates.
23 Add AES-GCM support to armv8crypto(4) providing accelerated
24 support for KTLS, IPsec, and other crypto API consumers.
27 The aesni(4) and armv8crypto(4) devices are now included in
28 GENERIC on amd64, i386, and arm64.
31 Add support for enforcing W^X mapping policy for user
32 processes. The policy is not enforced by default but can be
33 enabled by setting the kern.elf32.allow_wx and
34 kern.elf64.allow_wx sysctls to 0. Individual binaries can be
35 exempted from the policy by elfctl(1) via the wxneeded
39 Add AES-XTS support to armv8crypto(4) providing accelerated
40 software support for the default GELI cipher on arm64 systems.
43 Add aio_writev(2) and aio_readv(2), vectored analogues of aio_write(2)
47 The fusefs(5) protocol has been updated to 7.28. Support for
48 FUSE_COPY_FILE_RANGE and FUSE_LSEEK is added.
51 GDB 6.1.1 was removed. Users of crashinfo(8) should install the
52 gdb package or devel/gdb port.
55 The hme(4) driver was removed.
58 Fixes the case where gssd will not startup because /usr is a separate
59 local file system that is not yet mounted. It does not fix the case
60 where /usr is a separately mounted remote file system (such as NFS).
61 This latter case can be fixed by adding mountcritremote to the
62 REQUIRED line. Unfortunately doing so implies that all Kerberized
63 NFS mounts in /etc/fstab will need the "late" mount option.
64 This was not done, since the requirement for "late" would introduce
68 This commit added a new startup scripts variable called
69 nfsv4_server_only which uses the -R option on mountd added by r367026.
70 When nfsv4_server_only is set to "YES" in /etc/rc.conf, the NFS server
71 only handles NFSv4 and does not register with rpcbind. As such, rpcbind
72 does not need to be running. Useful for sites which consider rpcbind a
76 Kernel option ACPI_DMAR was renamed to IOMMU. amd64's IOMMU subsystem
77 was split out from amd64 DMAR support and is now generic, i.e., it can
78 be used by all architectures.
81 A series of commits ending with r364896 added NFS over TLS
82 to the kernel. This is believed to be compatible with
83 the Internet Draft titled "Towards Remote Procedure Call Encryption
84 By Default" (expected to soon become an RFC).
85 The mount_nfs(8) and exports(5) man pages describe the mount and
86 export option(s) related to NFS over TLS.
87 For NFS over TLS to work, the rpctlscd(8) { client } or rpctlssd(8)
88 { server } must be running on a kernel built with "options KERN_TLS"
89 on an architecture where PMAP_HAS_DMAP != 0.
92 Changes to one obscure devd event generated on resume need to
93 be documented. The old form will still be generated in 13, but not
97 Applications using regex(3), e.g. sed/grep, will no longer accept
98 redundant escapes for most ordinary characters.
101 SCTP support has been removed from GENERIC kernel configurations.
102 The SCTP stack is now built as sctp.ko and can be dynamically loaded.
105 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details.
108 The safexcel(4) crypto offload driver has been added.
111 nc(1) now implements SCTP mode, enabled by specifying the --sctp option.
114 A new implementation of bc and dc has been imported. It offers
115 better standards compliance, performance, localization and comes
116 with extensive test cases that are optionally installed.
117 Use WITHOUT_GH_BC=yes to build and install the world with the
118 previous version instead of the new one, if required.
121 struct export_args has changed so that the "user" specified for
122 the -maproot and -mapall exports(5) options may be in more than
126 sed(1) has learned about hex escapes (e.g. \x27) and will now do the
127 right thing with them, removing the need for printf magic or obnoxious
128 escaping in many scenarios.
130 r361238, r361798, r361799:
131 ZFS will now unconditionally reject read(2) of a directory with EISDIR.
132 Additionally, read(2) of a directory is now rejected with EISDIR by
133 default and may be re-enabled for non-ZFS filesystems that allow it with
134 the sysctl(8) MIB 'security.bsd.allow_read_dir'.
136 Aliases for grep to default to '-d skip' may be desired if commonly
137 non-recursively grepping a list that includes directories and the
138 possibility of EISDIR errors in stderr is not tolerable. Example
139 aliases, commented out, have been installed in /root/.cshrc and
143 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5).
144 exec.prepare runs before mounts, so can be used to populate new jails.
145 exec.release runs after unmounts, so can be used to remove ephemeral
148 r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936:
149 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5,
150 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from
151 the kernel open cryptographic framework (OCF).
154 Remove support for ARC4, Blowfish, Cast, DES, Triple DES,
155 MD5-HMAC, and Skipjack algorithms from /dev/crypto.
158 Remove support for DES, Triple DES, Blowfish, Cast, and
159 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC,
160 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4).
163 Remove support for Triple DES, Blowfish, and MD5 HMAC from
167 Remove support for DES, Triple DES, and RC4 from in-kernel GSS
174 init(8), service(8), and cron(8) will now adopt user/class environment
175 variables (excluding PATH, by default, which will be overwritten) by
176 default. Notably, environment variables for all cron jobs and rc
177 services can now be set via login.conf(5).
180 sparc64 has been removed from FreeBSD.
183 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
184 (RFC-8276) to the NFS client and server.
185 NFSv4.2 is comprised of several optional features that can be supported
186 in addition to NFSv4.1. This patch adds the following optional features:
187 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
189 - intra server file range copying via the copy_file_range(2) syscall
190 --> Avoiding data tranfer over the wire to/from the NFS client.
191 - lseek(SEEK_DATA/SEEK_HOLE)
192 - Extended attribute syscalls for "user" namespace attributes as defined
195 For the client, NFSv4.2 is only used if the mount command line option
196 minorversion=2 is specified.
197 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
198 and vfs.nfsd.server_max_minorversion4 have been added that allow
199 sysadmins to limit the minor versions of NFSv4 supported by the nfsd
201 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
205 armv5 support has been removed from FreeBSD.
208 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
211 sqlite3 is updated to sqlite3-3.30.1.
214 cron(8) now supports the -n (suppress mail on succesful run) and -q
215 (suppress logging of command execution) options in the crontab format.
216 See the crontab(5) manpage for details.
219 ntpd is no longer by default locked in memory. rlimit memlock 32
220 or rlimit memlock 0 can be used to restore this behaviour.
223 rc.subr(8) now honors ${name}_env in all rc(8) scripts. Previously,
224 environment variables set by a user via ${name}_env were ignored
225 if the service defined a custom *_cmd variable to control the behavior
226 of the run_rc_command function, e.g., start_cmd, instead of relying on
227 the variables like command and command_args,
229 r351770,r352920,r352922,r352923:
230 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync,
231 and iflag=fullblock flags, compatible with illumos and GNU.
234 Add kernel-side support for in-kernel Transport Layer Security
235 (KTLS). KTLS permits using sendfile(2) over sockets using
239 WPA is updated from 2.8 to 2.9.
242 Add probes for lockmgr(9) to the lockstat DTrace provider, add
243 corresponding lockstat(1) events, and document the new probes in
247 Intel RST is a new 'feature' that remaps NVMe devices from
248 their normal location to part of the AHCI bar space. This
249 will eliminate the need to set the BIOS SATA setting from RST
250 to AHCI causing the nvme drive to be erased before FreeBSD
251 will see the nvme drive. FreeBSD will now be able to see the
252 nvme drive now in the default config.
255 Add a vop_stdioctl() call, so that file systems that do not support
256 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
257 The algorithm appears to be compatible with the POSIX draft and
258 the implementation in Linux for the case of a file system that
259 does not support holes. Prior to this patch, lseek(2) would reply
260 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
261 file systems that do not support holes.
262 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
263 any other cases, such as a ENOTTY return from vn_bmap_seekhole().
266 The fuse driver has been renamed to fusefs(5) and been substantially
267 rewritten. The new driver includes many bug fixes and performance
268 enhancements, as well as the following user-visible features:
269 * Optional kernel-side permissions checks (-o default_permissions)
270 * mknod(2), socket(2), and pipe(2) support
271 * server side locking with fcntl(2)
272 * FUSE operations are now interruptible when mounted with -o intr
273 * server side handling of UTIME_NOW during utimensat(2)
274 * mount options may be updated with "mount -u"
275 * fusefs file system may now be exported over NFS
276 * RLIMIT_FSIZE support
277 * support for fuse file systems using protocols as old as 7.4
279 FUSE file system developers should also take note of the following new
281 * The protocol level has been raised from 7.8 to 7.23
282 * kqueue support on /dev/fuse
283 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY
286 gnop(8) can now configure a delay to be applied to read and write
287 request delays. See the -d, -q and -x parameters.
290 Adds a Linux compatible copy_file_range(2) syscall.
293 libcap_random(3) has been removed. Applications can use native
294 APIs to get random data in capability mode.
297 Add support for using unmapped mbufs with sendfile(2).
300 nand(4) and related components have been removed.
303 The UEFI loader now supports HTTP boot.
306 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
307 guests to play to and record audio data from the host.
310 swapon(8) can now erase a swap device immediately before enabling it,
311 similar to newfs(8)'s -E option. This behaviour can be specified by
312 adding -E to swapon(8)'s command-line parameters, or by adding the
313 "trimonce" option to a swap device's /etc/fstab entry.
316 The following network drivers have been removed: bm(4), cs(4), de(4),
317 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
321 Wired page accounting has been split into kernel wirings and user
322 wirings (e.g., by mlock(2)). Kernel wirings no long count towards
323 the global limit, which is renamed to vm.max_user_wired. bhyve -S
324 allocates user-wired memory and is now subject to that limit.
