1Release notes for FreeBSD 13.0. 2 3This file describes new user-visible features, changes and updates relevant to 4users of binary FreeBSD releases. Each entry should describe the change in no 5more than several sentences and should reference manual pages where an 6interested user can find more information. Entries should wrap after 80 7columns. Each entry should begin with one or more commit IDs on one line, 8specified as a comma separated list and/or range, followed by a colon and a 9newline. Entries should be separated by a newline. 10 11Changes to this file should not be MFCed. 12 1368e86d5265bc,e58dfd0de589,59f5a5cb724e,6e272a78de36,4c4a4fd4a649,ba2ae2cca63a: 14 sendmail has been updated to the latest upstream version (8.17.1). 15 16225443828ec6..c44d097dcf92: 17 bhyve now supports more than 16 vCPUs in a guest. By default 18 bhyve permits each guest to create the same number of vCPUs as 19 the count of physical CPUs on the host. This limit can be 20 adjusted via the loader tunable hw.vmm.maxcpu. 21 221462dc95f796: 23 Kernel TLS offload now supports receive-side offload of TLS 1.3. 24 253ee882bf21af: 26 Change handling of the lowest address on an IPv4 (sub)net so that 27 packets are not sent as a broadcast unless this has been set as the 28 broadcast address. This makes the lowest address usable for a host. 29 The old behavior can be restored with the net.inet.ip.broadcast_lowest 30 sysctl. For more information, see 31 https://datatracker.ietf.org/doc/draft-schoen-intarea-lowest-address/. 32 3333ff39796ffe,8719e8a951b7: 34 A new rc(8) service script zfskeys allows for automatic decryption 35 of ZFS datasets encrypted with ZFS native encryption during boot. 36 See the rc.conf(5) manual page for more information. 37 38b7a2cf0d9102 - eae02d959363: 39 Upgrade bhyve's emulation to version 1.4 of the NVMe specification 40 410a6760a1de32, 3f3676a71266, 580c04df4db6: 42 Add WiFi 6 support. 43 44various: 45 Add support for the HiFive Unmatched RISC-V board. 46 479fb6e613373c: 48 Add a sysctl called vfs.nfsd.srvmaxio that can be used to 49 increase the NFS server's maximum I/O size from 128Kbytes 50 to any power of 2 up to 1Mbyte. It can only be set when 51 the nfsd threads are not running and will normally require 52 an increase in kern.ipc.maxsockbuf to at least the value 53 recommended by the console log message generated when 54 setting vfs.nfsd.srvmaxio is first attempted. 55 569ec7dbf46b0a: 57 Add a new NFSv4.1/4.2 mount option "nconnect" that can 58 be used to specify the number of TCP connections that 59 will be used for the mount, up to a maximum of 16. 60 The first (default) TCP connection will be used for 61 all RPCs that consist of small RPC messages. 62 The RPCs that can consist of large RPC messages 63 (Read/Readdir/ReaddirPlus/Write) will be sent on the 64 additional TCP connections in a round robin fashion. 65 If either the NFS client or NFS server have multiple 66 network interfaces aggregated together or a network 67 interface that uses multiple queues, this can increase 68 NFS performance for the mount. 69 70various: 71 One True Awk has been updated to the latest from upstream 72 (20210215). All the FreeBSD patches, but one, have now been 73 either up streamed or discarded. Notable changes include: 74 o Locale is no longer used for ranges 75 o Various bugs fixed 76 o Better compatibility with gawk and mawk 77 78 The one FreeBSD change, likely to be removed in FreeBSD 14, is that 79 we still allow hex numbers, prefixed with 0x, to be parsed and 80 interpreted as hex numbers while all other awks (including one 81 true awk now) interpret them as 0 in line with awk's historic 82 behavior. 83 848a04edfdcbd2: 85 Change the default minor version used for an NFSv4 mount 86 to the highest minor version supported by the NFSv4 server. 87 This default can be overridden by using the "minorversion" 88 mount option. 89 902c76eebca71b, 59f6f5e23c1a: 91 Add two daemons rpc.tlsclntd(8) and rpc.tlsservd(8) that provide 92 support for NFS-over-TLS as described in the Internet Draft titled 93 "Towards Remote Procedure Call Encryption By Default". 94 These daemons are only built when WITH_OPENSSL_KTLS is specified 95 and are only tested on amd64 at this time. 96 They use KTLS to encrypt/decrypt all NFS RPC message traffic, plus 97 optional verification of machine identity via X.509 certificates. 98 99f76393a6305b6: 100 Add AES-GCM support to armv8crypto(4) providing accelerated 101 support for KTLS, IPsec, and other crypto API consumers. 102 103074a91f746bd: 104 The aesni(4) and armv8crypto(4) devices are now included in 105 GENERIC on amd64, i386, and arm64. 106 1072e1c94aa1fd5: 108 Add support for enforcing W^X mapping policy for user 109 processes. The policy is not enforced by default but can be 110 enabled by setting the kern.elf32.allow_wx and 111 kern.elf64.allow_wx sysctls to 0. Individual binaries can be 112 exempted from the policy by elfctl(1) via the wxneeded 113 feature. 114 1154979620ece98: 116 Add AES-XTS support to armv8crypto(4) providing accelerated 117 software support for the default GELI cipher on arm64 systems. 118 119022ca2fc7fe0: 120 Add aio_writev(2) and aio_readv(2), vectored analogues of aio_write(2) 121 and aio_read(2). 122 12392bbfe1f0d1f: 124 The fusefs(5) protocol has been updated to 7.28. Support for 125 FUSE_COPY_FILE_RANGE and FUSE_LSEEK is added. 126 127r368667: 128 GDB 6.1.1 was removed. Users of crashinfo(8) should install the 129 gdb package or devel/gdb port. 130 131r368559: 132 The hme(4) driver was removed. 133 134r367660: 135 Fixes the case where gssd will not startup because /usr is a separate 136 local file system that is not yet mounted. It does not fix the case 137 where /usr is a separately mounted remote file system (such as NFS). 138 This latter case can be fixed by adding mountcritremote to the 139 REQUIRED line. Unfortunately doing so implies that all Kerberized 140 NFS mounts in /etc/fstab will need the "late" mount option. 141 This was not done, since the requirement for "late" would introduce 142 a POLA violation. 143 144r367423: 145 This commit added a new startup scripts variable called 146 nfsv4_server_only which uses the -R option on mountd added by r367026. 147 When nfsv4_server_only is set to "YES" in /etc/rc.conf, the NFS server 148 only handles NFSv4 and does not register with rpcbind. As such, rpcbind 149 does not need to be running. Useful for sites which consider rpcbind a 150 security issue. 151 152r366267: 153 Kernel option ACPI_DMAR was renamed to IOMMU. amd64's IOMMU subsystem 154 was split out from amd64 DMAR support and is now generic, i.e., it can 155 be used by all architectures. 156 157r364896: 158 A series of commits ending with r364896 added NFS over TLS 159 to the kernel. This is believed to be compatible with 160 the Internet Draft titled "Towards Remote Procedure Call Encryption 161 By Default" (expected to soon become an RFC). 162 The mount_nfs(8) and exports(5) man pages describe the mount and 163 export option(s) related to NFS over TLS. 164 For NFS over TLS to work, the rpctlscd(8) { client } or rpctlssd(8) 165 { server } must be running on a kernel built with "options KERN_TLS" 166 on an architecture where PMAP_HAS_DMAP != 0. 167 168r364725: 169 Changes to one obscure devd event generated on resume need to 170 be documented. The old form will still be generated in 13, but not 171 in 14. 172 173r363679: 174 Applications using regex(3), e.g. sed/grep, will no longer accept 175 redundant escapes for most ordinary characters. 176 177r363253: 178 SCTP support has been removed from GENERIC kernel configurations. 179 The SCTP stack is now built as sctp.ko and can be dynamically loaded. 180 181r363233: 182 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details. 183 184r363180: 185 The safexcel(4) crypto offload driver has been added. 186 187r363084: 188 nc(1) now implements SCTP mode, enabled by specifying the --sctp option. 189 190r362681: 191 A new implementation of bc and dc has been imported. It offers 192 better standards compliance, performance, localization and comes 193 with extensive test cases that are optionally installed. 194 Use WITHOUT_GH_BC=yes to build and install the world with the 195 previous version instead of the new one, if required. 196 197r362158, r362163: 198 struct export_args has changed so that the "user" specified for 199 the -maproot and -mapall exports(5) options may be in more than 200 16 groups. 201 202r361884: 203 sed(1) has learned about hex escapes (e.g. \x27) and will now do the 204 right thing with them, removing the need for printf magic or obnoxious 205 escaping in many scenarios. 206 207r361238, r361798, r361799: 208 ZFS will now unconditionally reject read(2) of a directory with EISDIR. 209 Additionally, read(2) of a directory is now rejected with EISDIR by 210 default and may be re-enabled for non-ZFS filesystems that allow it with 211 the sysctl(8) MIB 'security.bsd.allow_read_dir'. 212 213 Aliases for grep to default to '-d skip' may be desired if commonly 214 non-recursively grepping a list that includes directories and the 215 possibility of EISDIR errors in stderr is not tolerable. Example 216 aliases, commented out, have been installed in /root/.cshrc and 217 /root/.shrc. 218 219r361066: 220 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5). 221 exec.prepare runs before mounts, so can be used to populate new jails. 222 exec.release runs after unmounts, so can be used to remove ephemeral 223 jails. 224 225r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936: 226 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5, 227 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from 228 the kernel open cryptographic framework (OCF). 229 230r360562: 231 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, 232 MD5-HMAC, and Skipjack algorithms from /dev/crypto. 233 234r360557: 235 Remove support for DES, Triple DES, Blowfish, Cast, and 236 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC, 237 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4). 238 239r359945: 240 Remove support for Triple DES, Blowfish, and MD5 HMAC from 241 geli(4). 242 243r359786-r359787: 244 Remove support for DES, Triple DES, and RC4 from in-kernel GSS 245 authentication. 246 247r357627: 248 remove elf2aout. 249 250r357560-r357565: 251 init(8), service(8), and cron(8) will now adopt user/class environment 252 variables (excluding PATH, by default, which will be overwritten) by 253 default. Notably, environment variables for all cron jobs and rc 254 services can now be set via login.conf(5). 255 256r357455: 257 sparc64 has been removed from FreeBSD. 258 259r355677: 260 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes 261 (RFC-8276) to the NFS client and server. 262 NFSv4.2 is comprised of several optional features that can be supported 263 in addition to NFSv4.1. This patch adds the following optional features: 264 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED) 265 - posix_fallocate() 266 - intra server file range copying via the copy_file_range(2) syscall 267 --> Avoiding data tranfer over the wire to/from the NFS client. 268 - lseek(SEEK_DATA/SEEK_HOLE) 269 - Extended attribute syscalls for "user" namespace attributes as defined 270 by RFC-8276. 271 272 For the client, NFSv4.2 is only used if the mount command line option 273 minorversion=2 is specified. 274 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4 275 and vfs.nfsd.server_max_minorversion4 have been added that allow 276 sysadmins to limit the minor versions of NFSv4 supported by the nfsd 277 server. 278 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2 279 on the server. 280 281r356263: 282 armv5 support has been removed from FreeBSD. 283 284r354517: 285 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices. 286 287r354269: 288 sqlite3 is updated to sqlite3-3.30.1. 289 290r352668: 291 cron(8) now supports the -n (suppress mail on succesful run) and -q 292 (suppress logging of command execution) options in the crontab format. 293 See the crontab(5) manpage for details. 294 295r352304: 296 ntpd is no longer by default locked in memory. rlimit memlock 32 297 or rlimit memlock 0 can be used to restore this behaviour. 298 299r351863: 300 rc.subr(8) now honors ${name}_env in all rc(8) scripts. Previously, 301 environment variables set by a user via ${name}_env were ignored 302 if the service defined a custom *_cmd variable to control the behavior 303 of the run_rc_command function, e.g., start_cmd, instead of relying on 304 the variables like command and command_args, 305 306r351770,r352920,r352922,r352923: 307 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync, 308 and iflag=fullblock flags, compatible with illumos and GNU. 309 310r351522: 311 Add kernel-side support for in-kernel Transport Layer Security 312 (KTLS). KTLS permits using sendfile(2) over sockets using 313 TLS. 314 315r351397: 316 WPA is updated from 2.8 to 2.9. 317 318r351361: 319 Add probes for lockmgr(9) to the lockstat DTrace provider, add 320 corresponding lockstat(1) events, and document the new probes in 321 dtrace_lockstat.4. 322 323r351356: 324 Intel RST is a new 'feature' that remaps NVMe devices from 325 their normal location to part of the AHCI bar space. This 326 will eliminate the need to set the BIOS SATA setting from RST 327 to AHCI causing the nvme drive to be erased before FreeBSD 328 will see the nvme drive. FreeBSD will now be able to see the 329 nvme drive now in the default config. 330 331r351201, r351372: 332 Add a vop_stdioctl() call, so that file systems that do not support 333 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE). 334 The algorithm appears to be compatible with the POSIX draft and 335 the implementation in Linux for the case of a file system that 336 does not support holes. Prior to this patch, lseek(2) would reply 337 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in 338 file systems that do not support holes. 339 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for 340 any other cases, such as a ENOTTY return from vn_bmap_seekhole(). 341 342r350665: 343 The fuse driver has been renamed to fusefs(5) and been substantially 344 rewritten. The new driver includes many bug fixes and performance 345 enhancements, as well as the following user-visible features: 346 * Optional kernel-side permissions checks (-o default_permissions) 347 * mknod(2), socket(2), and pipe(2) support 348 * server side locking with fcntl(2) 349 * FUSE operations are now interruptible when mounted with -o intr 350 * server side handling of UTIME_NOW during utimensat(2) 351 * mount options may be updated with "mount -u" 352 * fusefs file system may now be exported over NFS 353 * RLIMIT_FSIZE support 354 * support for fuse file systems using protocols as old as 7.4 355 356 FUSE file system developers should also take note of the following new 357 features: 358 * The protocol level has been raised from 7.8 to 7.23 359 * kqueue support on /dev/fuse 360 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY 361 362r350471: 363 gnop(8) can now configure a delay to be applied to read and write 364 request delays. See the -d, -q and -x parameters. 365 366r350315, r350316: 367 Adds a Linux compatible copy_file_range(2) syscall. 368 369r350307: 370 libcap_random(3) has been removed. Applications can use native 371 APIs to get random data in capability mode. 372 373r349529,r349530: 374 Add support for using unmapped mbufs with sendfile(2). 375 376r349352: 377 nand(4) and related components have been removed. 378 379r349349: 380 The UEFI loader now supports HTTP boot. 381 382r349335: 383 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing 384 guests to play to and record audio data from the host. 385 386r349286: 387 swapon(8) can now erase a swap device immediately before enabling it, 388 similar to newfs(8)'s -E option. This behaviour can be specified by 389 adding -E to swapon(8)'s command-line parameters, or by adding the 390 "trimonce" option to a swap device's /etc/fstab entry. 391 392r347908-r347923: 393 The following network drivers have been removed: bm(4), cs(4), de(4), 394 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4), 395 vx(4), wb(4), xe(4). 396 397r347532: 398 Wired page accounting has been split into kernel wirings and user 399 wirings (e.g., by mlock(2)). Kernel wirings no long count towards 400 the global limit, which is renamed to vm.max_user_wired. bhyve -S 401 allocates user-wired memory and is now subject to that limit. 402 403$FreeBSD$ 404
