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 130644746d5091: 14 Add a new "syskrb5" mount option for Kerberized NFSv4.1/4.2 mounts. 15 Without this patch, a Kerberized NFSv4.1/4.2 mount must provide 16 a Kerberos credential for the client at mount time. 17 This patch uses a feature of NFSv4.1/4.2 called SP4_NONE, which 18 allows the state maintenance operations to be performed by any 19 authentication mechanism, so that these operations may be done via 20 AUTH_SYS instead of RPCSEC_GSS (KerberosV). As such, no Kerberos 21 credential is required at mount time. 22 See mount_nfs(8). 23 24b4805d577787 and many others: 25 Add support so that nfsd(8), nfsuserd(8), mountd(8), gssd(8) 26 and rpc.tlsservd(8) can be run in an appropriately configured 27 vnet prison. The vnet prison must be on its own file system, 28 have the "allow.nfsd" jail parameter set on it and enforce_statfs 29 cannot be set to "0". Use of UDP and pNFS server configurations 30 are not permitted. (ie. The nfsd command line options "-u", "-p" 31 and "-m" are not supported.) 32 See jail(8), nfsd(8) and mountd(8). 33 3468e86d5265bc,e58dfd0de589,59f5a5cb724e,6e272a78de36,4c4a4fd4a649,ba2ae2cca63a: 35 sendmail has been updated to the latest upstream version (8.17.1). 36 37225443828ec6..c44d097dcf92: 38 bhyve now supports more than 16 vCPUs in a guest. By default 39 bhyve permits each guest to create the same number of vCPUs as 40 the count of physical CPUs on the host. This limit can be 41 adjusted via the loader tunable hw.vmm.maxcpu. 42 431462dc95f796: 44 Kernel TLS offload now supports receive-side offload of TLS 1.3. 45 463ee882bf21af: 47 Change handling of the lowest address on an IPv4 (sub)net so that 48 packets are not sent as a broadcast unless this has been set as the 49 broadcast address. This makes the lowest address usable for a host. 50 The old behavior can be restored with the net.inet.ip.broadcast_lowest 51 sysctl. For more information, see 52 https://datatracker.ietf.org/doc/draft-schoen-intarea-lowest-address/. 53 5433ff39796ffe,8719e8a951b7: 55 A new rc(8) service script zfskeys allows for automatic decryption 56 of ZFS datasets encrypted with ZFS native encryption during boot. 57 See the rc.conf(5) manual page for more information. 58 59b7a2cf0d9102 - eae02d959363: 60 Upgrade bhyve's emulation to version 1.4 of the NVMe specification 61 620a6760a1de32, 3f3676a71266, 580c04df4db6: 63 Add WiFi 6 support. 64 65various: 66 Add support for the HiFive Unmatched RISC-V board. 67 689fb6e613373c: 69 Add a sysctl called vfs.nfsd.srvmaxio that can be used to 70 increase the NFS server's maximum I/O size from 128Kbytes 71 to any power of 2 up to 1Mbyte. It can only be set when 72 the nfsd threads are not running and will normally require 73 an increase in kern.ipc.maxsockbuf to at least the value 74 recommended by the console log message generated when 75 setting vfs.nfsd.srvmaxio is first attempted. 76 779ec7dbf46b0a: 78 Add a new NFSv4.1/4.2 mount option "nconnect" that can 79 be used to specify the number of TCP connections that 80 will be used for the mount, up to a maximum of 16. 81 The first (default) TCP connection will be used for 82 all RPCs that consist of small RPC messages. 83 The RPCs that can consist of large RPC messages 84 (Read/Readdir/ReaddirPlus/Write) will be sent on the 85 additional TCP connections in a round robin fashion. 86 If either the NFS client or NFS server have multiple 87 network interfaces aggregated together or a network 88 interface that uses multiple queues, this can increase 89 NFS performance for the mount. 90 91various: 92 One True Awk has been updated to the latest from upstream 93 (20210215). All the FreeBSD patches, but one, have now been 94 either up streamed or discarded. Notable changes include: 95 o Locale is no longer used for ranges 96 o Various bugs fixed 97 o Better compatibility with gawk and mawk 98 99 The one FreeBSD change, likely to be removed in FreeBSD 14, is that 100 we still allow hex numbers, prefixed with 0x, to be parsed and 101 interpreted as hex numbers while all other awks (including one 102 true awk now) interpret them as 0 in line with awk's historic 103 behavior. 104 1058a04edfdcbd2: 106 Change the default minor version used for an NFSv4 mount 107 to the highest minor version supported by the NFSv4 server. 108 This default can be overridden by using the "minorversion" 109 mount option. 110 1112c76eebca71b, 59f6f5e23c1a: 112 Add two daemons rpc.tlsclntd(8) and rpc.tlsservd(8) that provide 113 support for NFS-over-TLS as described in the Internet Draft titled 114 "Towards Remote Procedure Call Encryption By Default". 115 These daemons are only built when WITH_OPENSSL_KTLS is specified 116 and are only tested on amd64 at this time. 117 They use KTLS to encrypt/decrypt all NFS RPC message traffic, plus 118 optional verification of machine identity via X.509 certificates. 119 120f76393a6305b6: 121 Add AES-GCM support to armv8crypto(4) providing accelerated 122 support for KTLS, IPsec, and other crypto API consumers. 123 124074a91f746bd: 125 The aesni(4) and armv8crypto(4) devices are now included in 126 GENERIC on amd64, i386, and arm64. 127 1282e1c94aa1fd5: 129 Add support for enforcing W^X mapping policy for user 130 processes. The policy is not enforced by default but can be 131 enabled by setting the kern.elf32.allow_wx and 132 kern.elf64.allow_wx sysctls to 0. Individual binaries can be 133 exempted from the policy by elfctl(1) via the wxneeded 134 feature. 135 1364979620ece98: 137 Add AES-XTS support to armv8crypto(4) providing accelerated 138 software support for the default GELI cipher on arm64 systems. 139 140022ca2fc7fe0: 141 Add aio_writev(2) and aio_readv(2), vectored analogues of aio_write(2) 142 and aio_read(2). 143 14492bbfe1f0d1f: 145 The fusefs(5) protocol has been updated to 7.28. Support for 146 FUSE_COPY_FILE_RANGE and FUSE_LSEEK is added. 147 148r368667: 149 GDB 6.1.1 was removed. Users of crashinfo(8) should install the 150 gdb package or devel/gdb port. 151 152r368559: 153 The hme(4) driver was removed. 154 155r367660: 156 Fixes the case where gssd will not startup because /usr is a separate 157 local file system that is not yet mounted. It does not fix the case 158 where /usr is a separately mounted remote file system (such as NFS). 159 This latter case can be fixed by adding mountcritremote to the 160 REQUIRED line. Unfortunately doing so implies that all Kerberized 161 NFS mounts in /etc/fstab will need the "late" mount option. 162 This was not done, since the requirement for "late" would introduce 163 a POLA violation. 164 165r367423: 166 This commit added a new startup scripts variable called 167 nfsv4_server_only which uses the -R option on mountd added by r367026. 168 When nfsv4_server_only is set to "YES" in /etc/rc.conf, the NFS server 169 only handles NFSv4 and does not register with rpcbind. As such, rpcbind 170 does not need to be running. Useful for sites which consider rpcbind a 171 security issue. 172 173r366267: 174 Kernel option ACPI_DMAR was renamed to IOMMU. amd64's IOMMU subsystem 175 was split out from amd64 DMAR support and is now generic, i.e., it can 176 be used by all architectures. 177 178r364896: 179 A series of commits ending with r364896 added NFS over TLS 180 to the kernel. This is believed to be compatible with 181 the Internet Draft titled "Towards Remote Procedure Call Encryption 182 By Default" (expected to soon become an RFC). 183 The mount_nfs(8) and exports(5) man pages describe the mount and 184 export option(s) related to NFS over TLS. 185 For NFS over TLS to work, the rpctlscd(8) { client } or rpctlssd(8) 186 { server } must be running on a kernel built with "options KERN_TLS" 187 on an architecture where PMAP_HAS_DMAP != 0. 188 189r364725: 190 Changes to one obscure devd event generated on resume need to 191 be documented. The old form will still be generated in 13, but not 192 in 14. 193 194r363679: 195 Applications using regex(3), e.g. sed/grep, will no longer accept 196 redundant escapes for most ordinary characters. 197 198r363253: 199 SCTP support has been removed from GENERIC kernel configurations. 200 The SCTP stack is now built as sctp.ko and can be dynamically loaded. 201 202r363233: 203 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details. 204 205r363180: 206 The safexcel(4) crypto offload driver has been added. 207 208r363084: 209 nc(1) now implements SCTP mode, enabled by specifying the --sctp option. 210 211r362681: 212 A new implementation of bc and dc has been imported. It offers 213 better standards compliance, performance, localization and comes 214 with extensive test cases that are optionally installed. 215 Use WITHOUT_GH_BC=yes to build and install the world with the 216 previous version instead of the new one, if required. 217 218r362158, r362163: 219 struct export_args has changed so that the "user" specified for 220 the -maproot and -mapall exports(5) options may be in more than 221 16 groups. 222 223r361884: 224 sed(1) has learned about hex escapes (e.g. \x27) and will now do the 225 right thing with them, removing the need for printf magic or obnoxious 226 escaping in many scenarios. 227 228r361238, r361798, r361799: 229 ZFS will now unconditionally reject read(2) of a directory with EISDIR. 230 Additionally, read(2) of a directory is now rejected with EISDIR by 231 default and may be re-enabled for non-ZFS filesystems that allow it with 232 the sysctl(8) MIB 'security.bsd.allow_read_dir'. 233 234 Aliases for grep to default to '-d skip' may be desired if commonly 235 non-recursively grepping a list that includes directories and the 236 possibility of EISDIR errors in stderr is not tolerable. Example 237 aliases, commented out, have been installed in /root/.cshrc and 238 /root/.shrc. 239 240r361066: 241 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5). 242 exec.prepare runs before mounts, so can be used to populate new jails. 243 exec.release runs after unmounts, so can be used to remove ephemeral 244 jails. 245 246r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936: 247 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5, 248 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from 249 the kernel open cryptographic framework (OCF). 250 251r360562: 252 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, 253 MD5-HMAC, and Skipjack algorithms from /dev/crypto. 254 255r360557: 256 Remove support for DES, Triple DES, Blowfish, Cast, and 257 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC, 258 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4). 259 260r359945: 261 Remove support for Triple DES, Blowfish, and MD5 HMAC from 262 geli(4). 263 264r359786-r359787: 265 Remove support for DES, Triple DES, and RC4 from in-kernel GSS 266 authentication. 267 268r357627: 269 remove elf2aout. 270 271r357560-r357565: 272 init(8), service(8), and cron(8) will now adopt user/class environment 273 variables (excluding PATH, by default, which will be overwritten) by 274 default. Notably, environment variables for all cron jobs and rc 275 services can now be set via login.conf(5). 276 277r357455: 278 sparc64 has been removed from FreeBSD. 279 280r355677: 281 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes 282 (RFC-8276) to the NFS client and server. 283 NFSv4.2 is comprised of several optional features that can be supported 284 in addition to NFSv4.1. This patch adds the following optional features: 285 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED) 286 - posix_fallocate() 287 - intra server file range copying via the copy_file_range(2) syscall 288 --> Avoiding data tranfer over the wire to/from the NFS client. 289 - lseek(SEEK_DATA/SEEK_HOLE) 290 - Extended attribute syscalls for "user" namespace attributes as defined 291 by RFC-8276. 292 293 For the client, NFSv4.2 is only used if the mount command line option 294 minorversion=2 is specified. 295 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4 296 and vfs.nfsd.server_max_minorversion4 have been added that allow 297 sysadmins to limit the minor versions of NFSv4 supported by the nfsd 298 server. 299 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2 300 on the server. 301 302r356263: 303 armv5 support has been removed from FreeBSD. 304 305r354517: 306 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices. 307 308r354269: 309 sqlite3 is updated to sqlite3-3.30.1. 310 311r352668: 312 cron(8) now supports the -n (suppress mail on succesful run) and -q 313 (suppress logging of command execution) options in the crontab format. 314 See the crontab(5) manpage for details. 315 316r352304: 317 ntpd is no longer by default locked in memory. rlimit memlock 32 318 or rlimit memlock 0 can be used to restore this behaviour. 319 320r351863: 321 rc.subr(8) now honors ${name}_env in all rc(8) scripts. Previously, 322 environment variables set by a user via ${name}_env were ignored 323 if the service defined a custom *_cmd variable to control the behavior 324 of the run_rc_command function, e.g., start_cmd, instead of relying on 325 the variables like command and command_args, 326 327r351770,r352920,r352922,r352923: 328 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync, 329 and iflag=fullblock flags, compatible with illumos and GNU. 330 331r351522: 332 Add kernel-side support for in-kernel Transport Layer Security 333 (KTLS). KTLS permits using sendfile(2) over sockets using 334 TLS. 335 336r351397: 337 WPA is updated from 2.8 to 2.9. 338 339r351361: 340 Add probes for lockmgr(9) to the lockstat DTrace provider, add 341 corresponding lockstat(1) events, and document the new probes in 342 dtrace_lockstat.4. 343 344r351356: 345 Intel RST is a new 'feature' that remaps NVMe devices from 346 their normal location to part of the AHCI bar space. This 347 will eliminate the need to set the BIOS SATA setting from RST 348 to AHCI causing the nvme drive to be erased before FreeBSD 349 will see the nvme drive. FreeBSD will now be able to see the 350 nvme drive now in the default config. 351 352r351201, r351372: 353 Add a vop_stdioctl() call, so that file systems that do not support 354 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE). 355 The algorithm appears to be compatible with the POSIX draft and 356 the implementation in Linux for the case of a file system that 357 does not support holes. Prior to this patch, lseek(2) would reply 358 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in 359 file systems that do not support holes. 360 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for 361 any other cases, such as a ENOTTY return from vn_bmap_seekhole(). 362 363r350665: 364 The fuse driver has been renamed to fusefs(5) and been substantially 365 rewritten. The new driver includes many bug fixes and performance 366 enhancements, as well as the following user-visible features: 367 * Optional kernel-side permissions checks (-o default_permissions) 368 * mknod(2), socket(2), and pipe(2) support 369 * server side locking with fcntl(2) 370 * FUSE operations are now interruptible when mounted with -o intr 371 * server side handling of UTIME_NOW during utimensat(2) 372 * mount options may be updated with "mount -u" 373 * fusefs file system may now be exported over NFS 374 * RLIMIT_FSIZE support 375 * support for fuse file systems using protocols as old as 7.4 376 377 FUSE file system developers should also take note of the following new 378 features: 379 * The protocol level has been raised from 7.8 to 7.23 380 * kqueue support on /dev/fuse 381 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY 382 383r350471: 384 gnop(8) can now configure a delay to be applied to read and write 385 request delays. See the -d, -q and -x parameters. 386 387r350315, r350316: 388 Adds a Linux compatible copy_file_range(2) syscall. 389 390r350307: 391 libcap_random(3) has been removed. Applications can use native 392 APIs to get random data in capability mode. 393 394r349529,r349530: 395 Add support for using unmapped mbufs with sendfile(2). 396 397r349352: 398 nand(4) and related components have been removed. 399 400r349349: 401 The UEFI loader now supports HTTP boot. 402 403r349335: 404 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing 405 guests to play to and record audio data from the host. 406 407r349286: 408 swapon(8) can now erase a swap device immediately before enabling it, 409 similar to newfs(8)'s -E option. This behaviour can be specified by 410 adding -E to swapon(8)'s command-line parameters, or by adding the 411 "trimonce" option to a swap device's /etc/fstab entry. 412 413r347908-r347923: 414 The following network drivers have been removed: bm(4), cs(4), de(4), 415 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4), 416 vx(4), wb(4), xe(4). 417 418r347532: 419 Wired page accounting has been split into kernel wirings and user 420 wirings (e.g., by mlock(2)). Kernel wirings no long count towards 421 the global limit, which is renamed to vm.max_user_wired. bhyve -S 422 allocates user-wired memory and is now subject to that limit. 423
