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 130a6760a1de32, 3f3676a71266, 580c04df4db6: 14 Add WiFi 6 support. 15 16various: 17 Add support for the HiFive Unmatched RISC-V board. 18 199fb6e613373c: 20 Add a sysctl called vfs.nfsd.srvmaxio that can be used to 21 increase the NFS server's maximum I/O size from 128Kbytes 22 to any power of 2 up to 1Mbyte. It can only be set when 23 the nfsd threads are not running and will normally require 24 an increase in kern.ipc.maxsockbuf to at least the value 25 recommended by the console log message generated when 26 setting vfs.nfsd.srvmaxio is first attempted. 27 289ec7dbf46b0a: 29 Add a new NFSv4.1/4.2 mount option "nconnect" that can 30 be used to specify the number of TCP connections that 31 will be used for the mount, up to a maximum of 16. 32 The first (default) TCP connection will be used for 33 all RPCs that consist of small RPC messages. 34 The RPCs that can consist of large RPC messages 35 (Read/Readdir/ReaddirPlus/Write) will be sent on the 36 additional TCP connections in a round robin fashion. 37 If either the NFS client or NFS server have multiple 38 network interfaces aggregated together or a network 39 interface that uses multiple queues, this can increase 40 NFS performance for the mount. 41 42various: 43 One True Awk has been updated to the latest from upstream 44 (20210215). All the FreeBSD patches, but one, have now been 45 either up streamed or discarded. Notable changes include: 46 o Locale is no longer used for ranges 47 o Various bugs fixed 48 o Better compatibility with gawk and mawk 49 50 The one FreeBSD change, likely to be removed in FreeBSD 14, is that 51 we still allow hex numbers, prefixed with 0x, to be parsed and 52 interpreted as hex numbers while all other awks (including one 53 true awk now) interpret them as 0 in line with awk's historic 54 behavior. 55 568a04edfdcbd2: 57 Change the default minor version used for an NFSv4 mount 58 to the highest minor version supported by the NFSv4 server. 59 This default can be overridden by using the "minorversion" 60 mount option. 61 622c76eebca71b, 59f6f5e23c1a: 63 Add two daemons rpc.tlsclntd(8) and rpc.tlsservd(8) that provide 64 support for NFS-over-TLS as described in the Internet Draft titled 65 "Towards Remote Procedure Call Encryption By Default". 66 These daemons are only built when WITH_OPENSSL_KTLS is specified 67 and are only tested on amd64 at this time. 68 They use KTLS to encrypt/decrypt all NFS RPC message traffic, plus 69 optional verification of machine identity via X.509 certificates. 70 71f76393a6305b6: 72 Add AES-GCM support to armv8crypto(4) providing accelerated 73 support for KTLS, IPsec, and other crypto API consumers. 74 75074a91f746bd: 76 The aesni(4) and armv8crypto(4) devices are now included in 77 GENERIC on amd64, i386, and arm64. 78 792e1c94aa1fd5: 80 Add support for enforcing W^X mapping policy for user 81 processes. The policy is not enforced by default but can be 82 enabled by setting the kern.elf32.allow_wx and 83 kern.elf64.allow_wx sysctls to 0. Individual binaries can be 84 exempted from the policy by elfctl(1) via the wxneeded 85 feature. 86 874979620ece98: 88 Add AES-XTS support to armv8crypto(4) providing accelerated 89 software support for the default GELI cipher on arm64 systems. 90 91022ca2fc7fe0: 92 Add aio_writev(2) and aio_readv(2), vectored analogues of aio_write(2) 93 and aio_read(2). 94 9592bbfe1f0d1f: 96 The fusefs(5) protocol has been updated to 7.28. Support for 97 FUSE_COPY_FILE_RANGE and FUSE_LSEEK is added. 98 99r368667: 100 GDB 6.1.1 was removed. Users of crashinfo(8) should install the 101 gdb package or devel/gdb port. 102 103r368559: 104 The hme(4) driver was removed. 105 106r367660: 107 Fixes the case where gssd will not startup because /usr is a separate 108 local file system that is not yet mounted. It does not fix the case 109 where /usr is a separately mounted remote file system (such as NFS). 110 This latter case can be fixed by adding mountcritremote to the 111 REQUIRED line. Unfortunately doing so implies that all Kerberized 112 NFS mounts in /etc/fstab will need the "late" mount option. 113 This was not done, since the requirement for "late" would introduce 114 a POLA violation. 115 116r367423: 117 This commit added a new startup scripts variable called 118 nfsv4_server_only which uses the -R option on mountd added by r367026. 119 When nfsv4_server_only is set to "YES" in /etc/rc.conf, the NFS server 120 only handles NFSv4 and does not register with rpcbind. As such, rpcbind 121 does not need to be running. Useful for sites which consider rpcbind a 122 security issue. 123 124r366267: 125 Kernel option ACPI_DMAR was renamed to IOMMU. amd64's IOMMU subsystem 126 was split out from amd64 DMAR support and is now generic, i.e., it can 127 be used by all architectures. 128 129r364896: 130 A series of commits ending with r364896 added NFS over TLS 131 to the kernel. This is believed to be compatible with 132 the Internet Draft titled "Towards Remote Procedure Call Encryption 133 By Default" (expected to soon become an RFC). 134 The mount_nfs(8) and exports(5) man pages describe the mount and 135 export option(s) related to NFS over TLS. 136 For NFS over TLS to work, the rpctlscd(8) { client } or rpctlssd(8) 137 { server } must be running on a kernel built with "options KERN_TLS" 138 on an architecture where PMAP_HAS_DMAP != 0. 139 140r364725: 141 Changes to one obscure devd event generated on resume need to 142 be documented. The old form will still be generated in 13, but not 143 in 14. 144 145r363679: 146 Applications using regex(3), e.g. sed/grep, will no longer accept 147 redundant escapes for most ordinary characters. 148 149r363253: 150 SCTP support has been removed from GENERIC kernel configurations. 151 The SCTP stack is now built as sctp.ko and can be dynamically loaded. 152 153r363233: 154 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details. 155 156r363180: 157 The safexcel(4) crypto offload driver has been added. 158 159r363084: 160 nc(1) now implements SCTP mode, enabled by specifying the --sctp option. 161 162r362681: 163 A new implementation of bc and dc has been imported. It offers 164 better standards compliance, performance, localization and comes 165 with extensive test cases that are optionally installed. 166 Use WITHOUT_GH_BC=yes to build and install the world with the 167 previous version instead of the new one, if required. 168 169r362158, r362163: 170 struct export_args has changed so that the "user" specified for 171 the -maproot and -mapall exports(5) options may be in more than 172 16 groups. 173 174r361884: 175 sed(1) has learned about hex escapes (e.g. \x27) and will now do the 176 right thing with them, removing the need for printf magic or obnoxious 177 escaping in many scenarios. 178 179r361238, r361798, r361799: 180 ZFS will now unconditionally reject read(2) of a directory with EISDIR. 181 Additionally, read(2) of a directory is now rejected with EISDIR by 182 default and may be re-enabled for non-ZFS filesystems that allow it with 183 the sysctl(8) MIB 'security.bsd.allow_read_dir'. 184 185 Aliases for grep to default to '-d skip' may be desired if commonly 186 non-recursively grepping a list that includes directories and the 187 possibility of EISDIR errors in stderr is not tolerable. Example 188 aliases, commented out, have been installed in /root/.cshrc and 189 /root/.shrc. 190 191r361066: 192 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5). 193 exec.prepare runs before mounts, so can be used to populate new jails. 194 exec.release runs after unmounts, so can be used to remove ephemeral 195 jails. 196 197r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936: 198 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5, 199 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from 200 the kernel open cryptographic framework (OCF). 201 202r360562: 203 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, 204 MD5-HMAC, and Skipjack algorithms from /dev/crypto. 205 206r360557: 207 Remove support for DES, Triple DES, Blowfish, Cast, and 208 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC, 209 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4). 210 211r359945: 212 Remove support for Triple DES, Blowfish, and MD5 HMAC from 213 geli(4). 214 215r359786-r359787: 216 Remove support for DES, Triple DES, and RC4 from in-kernel GSS 217 authentication. 218 219r357627: 220 remove elf2aout. 221 222r357560-r357565: 223 init(8), service(8), and cron(8) will now adopt user/class environment 224 variables (excluding PATH, by default, which will be overwritten) by 225 default. Notably, environment variables for all cron jobs and rc 226 services can now be set via login.conf(5). 227 228r357455: 229 sparc64 has been removed from FreeBSD. 230 231r355677: 232 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes 233 (RFC-8276) to the NFS client and server. 234 NFSv4.2 is comprised of several optional features that can be supported 235 in addition to NFSv4.1. This patch adds the following optional features: 236 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED) 237 - posix_fallocate() 238 - intra server file range copying via the copy_file_range(2) syscall 239 --> Avoiding data tranfer over the wire to/from the NFS client. 240 - lseek(SEEK_DATA/SEEK_HOLE) 241 - Extended attribute syscalls for "user" namespace attributes as defined 242 by RFC-8276. 243 244 For the client, NFSv4.2 is only used if the mount command line option 245 minorversion=2 is specified. 246 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4 247 and vfs.nfsd.server_max_minorversion4 have been added that allow 248 sysadmins to limit the minor versions of NFSv4 supported by the nfsd 249 server. 250 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2 251 on the server. 252 253r356263: 254 armv5 support has been removed from FreeBSD. 255 256r354517: 257 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices. 258 259r354269: 260 sqlite3 is updated to sqlite3-3.30.1. 261 262r352668: 263 cron(8) now supports the -n (suppress mail on succesful run) and -q 264 (suppress logging of command execution) options in the crontab format. 265 See the crontab(5) manpage for details. 266 267r352304: 268 ntpd is no longer by default locked in memory. rlimit memlock 32 269 or rlimit memlock 0 can be used to restore this behaviour. 270 271r351863: 272 rc.subr(8) now honors ${name}_env in all rc(8) scripts. Previously, 273 environment variables set by a user via ${name}_env were ignored 274 if the service defined a custom *_cmd variable to control the behavior 275 of the run_rc_command function, e.g., start_cmd, instead of relying on 276 the variables like command and command_args, 277 278r351770,r352920,r352922,r352923: 279 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync, 280 and iflag=fullblock flags, compatible with illumos and GNU. 281 282r351522: 283 Add kernel-side support for in-kernel Transport Layer Security 284 (KTLS). KTLS permits using sendfile(2) over sockets using 285 TLS. 286 287r351397: 288 WPA is updated from 2.8 to 2.9. 289 290r351361: 291 Add probes for lockmgr(9) to the lockstat DTrace provider, add 292 corresponding lockstat(1) events, and document the new probes in 293 dtrace_lockstat.4. 294 295r351356: 296 Intel RST is a new 'feature' that remaps NVMe devices from 297 their normal location to part of the AHCI bar space. This 298 will eliminate the need to set the BIOS SATA setting from RST 299 to AHCI causing the nvme drive to be erased before FreeBSD 300 will see the nvme drive. FreeBSD will now be able to see the 301 nvme drive now in the default config. 302 303r351201, r351372: 304 Add a vop_stdioctl() call, so that file systems that do not support 305 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE). 306 The algorithm appears to be compatible with the POSIX draft and 307 the implementation in Linux for the case of a file system that 308 does not support holes. Prior to this patch, lseek(2) would reply 309 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in 310 file systems that do not support holes. 311 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for 312 any other cases, such as a ENOTTY return from vn_bmap_seekhole(). 313 314r350665: 315 The fuse driver has been renamed to fusefs(5) and been substantially 316 rewritten. The new driver includes many bug fixes and performance 317 enhancements, as well as the following user-visible features: 318 * Optional kernel-side permissions checks (-o default_permissions) 319 * mknod(2), socket(2), and pipe(2) support 320 * server side locking with fcntl(2) 321 * FUSE operations are now interruptible when mounted with -o intr 322 * server side handling of UTIME_NOW during utimensat(2) 323 * mount options may be updated with "mount -u" 324 * fusefs file system may now be exported over NFS 325 * RLIMIT_FSIZE support 326 * support for fuse file systems using protocols as old as 7.4 327 328 FUSE file system developers should also take note of the following new 329 features: 330 * The protocol level has been raised from 7.8 to 7.23 331 * kqueue support on /dev/fuse 332 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY 333 334r350471: 335 gnop(8) can now configure a delay to be applied to read and write 336 request delays. See the -d, -q and -x parameters. 337 338r350315, r350316: 339 Adds a Linux compatible copy_file_range(2) syscall. 340 341r350307: 342 libcap_random(3) has been removed. Applications can use native 343 APIs to get random data in capability mode. 344 345r349529,r349530: 346 Add support for using unmapped mbufs with sendfile(2). 347 348r349352: 349 nand(4) and related components have been removed. 350 351r349349: 352 The UEFI loader now supports HTTP boot. 353 354r349335: 355 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing 356 guests to play to and record audio data from the host. 357 358r349286: 359 swapon(8) can now erase a swap device immediately before enabling it, 360 similar to newfs(8)'s -E option. This behaviour can be specified by 361 adding -E to swapon(8)'s command-line parameters, or by adding the 362 "trimonce" option to a swap device's /etc/fstab entry. 363 364r347908-r347923: 365 The following network drivers have been removed: bm(4), cs(4), de(4), 366 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4), 367 vx(4), wb(4), xe(4). 368 369r347532: 370 Wired page accounting has been split into kernel wirings and user 371 wirings (e.g., by mlock(2)). Kernel wirings no long count towards 372 the global limit, which is renamed to vm.max_user_wired. bhyve -S 373 allocates user-wired memory and is now subject to that limit. 374 375$FreeBSD$ 376
