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 13various: 14 Add support for the HiFive Unmatched RISC-V board. 15 169fb6e613373c: 17 Add a sysctl called vfs.nfsd.srvmaxio that can be used to 18 increase the NFS server's maximum I/O size from 128Kbytes 19 to any power of 2 up to 1Mbyte. It can only be set when 20 the nfsd threads are not running and will normally require 21 an increase in kern.ipc.maxsockbuf to at least the value 22 recommended by the console log message generated when 23 setting vfs.nfsd.srvmaxio is first attempted. 24 259ec7dbf46b0a: 26 Add a new NFSv4.1/4.2 mount option "nconnect" that can 27 be used to specify the number of TCP connections that 28 will be used for the mount, up to a maximum of 16. 29 The first (default) TCP connection will be used for 30 all RPCs that consist of small RPC messages. 31 The RPCs that can consist of large RPC messages 32 (Read/Readdir/ReaddirPlus/Write) will be sent on the 33 additional TCP connections in a round robin fashion. 34 If either the NFS client or NFS server have multiple 35 network interfaces aggregated together or a network 36 interface that uses multiple queues, this can increase 37 NFS performance for the mount. 38 39various: 40 One True Awk has been updated to the latest from upstream 41 (20210215). All the FreeBSD patches, but one, have now been 42 either up streamed or discarded. Notable changes include: 43 o Locale is no longer used for ranges 44 o Various bugs fixed 45 o Better compatibility with gawk and mawk 46 47 The one FreeBSD change, likely to be removed in FreeBSD 14, is that 48 we still allow hex numbers, prefixed with 0x, to be parsed and 49 interpreted as hex numbers while all other awks (including one 50 true awk now) interpret them as 0 in line with awk's historic 51 behavior. 52 538a04edfdcbd2: 54 Change the default minor version used for an NFSv4 mount 55 to the highest minor version supported by the NFSv4 server. 56 This default can be overridden by using the "minorversion" 57 mount option. 58 592c76eebca71b, 59f6f5e23c1a: 60 Add two daemons rpc.tlsclntd(8) and rpc.tlsservd(8) that provide 61 support for NFS-over-TLS as described in the Internet Draft titled 62 "Towards Remote Procedure Call Encryption By Default". 63 These daemons are only built when WITH_OPENSSL_KTLS is specified 64 and are only tested on amd64 at this time. 65 They use KTLS to encrypt/decrypt all NFS RPC message traffic, plus 66 optional verification of machine identity via X.509 certificates. 67 68f76393a6305b6: 69 Add AES-GCM support to armv8crypto(4) providing accelerated 70 support for KTLS, IPsec, and other crypto API consumers. 71 72074a91f746bd: 73 The aesni(4) and armv8crypto(4) devices are now included in 74 GENERIC on amd64, i386, and arm64. 75 762e1c94aa1fd5: 77 Add support for enforcing W^X mapping policy for user 78 processes. The policy is not enforced by default but can be 79 enabled by setting the kern.elf32.allow_wx and 80 kern.elf64.allow_wx sysctls to 0. Individual binaries can be 81 exempted from the policy by elfctl(1) via the wxneeded 82 feature. 83 844979620ece98: 85 Add AES-XTS support to armv8crypto(4) providing accelerated 86 software support for the default GELI cipher on arm64 systems. 87 88022ca2fc7fe0: 89 Add aio_writev(2) and aio_readv(2), vectored analogues of aio_write(2) 90 and aio_read(2). 91 9292bbfe1f0d1f: 93 The fusefs(5) protocol has been updated to 7.28. Support for 94 FUSE_COPY_FILE_RANGE and FUSE_LSEEK is added. 95 96r368667: 97 GDB 6.1.1 was removed. Users of crashinfo(8) should install the 98 gdb package or devel/gdb port. 99 100r368559: 101 The hme(4) driver was removed. 102 103r367660: 104 Fixes the case where gssd will not startup because /usr is a separate 105 local file system that is not yet mounted. It does not fix the case 106 where /usr is a separately mounted remote file system (such as NFS). 107 This latter case can be fixed by adding mountcritremote to the 108 REQUIRED line. Unfortunately doing so implies that all Kerberized 109 NFS mounts in /etc/fstab will need the "late" mount option. 110 This was not done, since the requirement for "late" would introduce 111 a POLA violation. 112 113r367423: 114 This commit added a new startup scripts variable called 115 nfsv4_server_only which uses the -R option on mountd added by r367026. 116 When nfsv4_server_only is set to "YES" in /etc/rc.conf, the NFS server 117 only handles NFSv4 and does not register with rpcbind. As such, rpcbind 118 does not need to be running. Useful for sites which consider rpcbind a 119 security issue. 120 121r366267: 122 Kernel option ACPI_DMAR was renamed to IOMMU. amd64's IOMMU subsystem 123 was split out from amd64 DMAR support and is now generic, i.e., it can 124 be used by all architectures. 125 126r364896: 127 A series of commits ending with r364896 added NFS over TLS 128 to the kernel. This is believed to be compatible with 129 the Internet Draft titled "Towards Remote Procedure Call Encryption 130 By Default" (expected to soon become an RFC). 131 The mount_nfs(8) and exports(5) man pages describe the mount and 132 export option(s) related to NFS over TLS. 133 For NFS over TLS to work, the rpctlscd(8) { client } or rpctlssd(8) 134 { server } must be running on a kernel built with "options KERN_TLS" 135 on an architecture where PMAP_HAS_DMAP != 0. 136 137r364725: 138 Changes to one obscure devd event generated on resume need to 139 be documented. The old form will still be generated in 13, but not 140 in 14. 141 142r363679: 143 Applications using regex(3), e.g. sed/grep, will no longer accept 144 redundant escapes for most ordinary characters. 145 146r363253: 147 SCTP support has been removed from GENERIC kernel configurations. 148 The SCTP stack is now built as sctp.ko and can be dynamically loaded. 149 150r363233: 151 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details. 152 153r363180: 154 The safexcel(4) crypto offload driver has been added. 155 156r363084: 157 nc(1) now implements SCTP mode, enabled by specifying the --sctp option. 158 159r362681: 160 A new implementation of bc and dc has been imported. It offers 161 better standards compliance, performance, localization and comes 162 with extensive test cases that are optionally installed. 163 Use WITHOUT_GH_BC=yes to build and install the world with the 164 previous version instead of the new one, if required. 165 166r362158, r362163: 167 struct export_args has changed so that the "user" specified for 168 the -maproot and -mapall exports(5) options may be in more than 169 16 groups. 170 171r361884: 172 sed(1) has learned about hex escapes (e.g. \x27) and will now do the 173 right thing with them, removing the need for printf magic or obnoxious 174 escaping in many scenarios. 175 176r361238, r361798, r361799: 177 ZFS will now unconditionally reject read(2) of a directory with EISDIR. 178 Additionally, read(2) of a directory is now rejected with EISDIR by 179 default and may be re-enabled for non-ZFS filesystems that allow it with 180 the sysctl(8) MIB 'security.bsd.allow_read_dir'. 181 182 Aliases for grep to default to '-d skip' may be desired if commonly 183 non-recursively grepping a list that includes directories and the 184 possibility of EISDIR errors in stderr is not tolerable. Example 185 aliases, commented out, have been installed in /root/.cshrc and 186 /root/.shrc. 187 188r361066: 189 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5). 190 exec.prepare runs before mounts, so can be used to populate new jails. 191 exec.release runs after unmounts, so can be used to remove ephemeral 192 jails. 193 194r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936: 195 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5, 196 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from 197 the kernel open cryptographic framework (OCF). 198 199r360562: 200 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, 201 MD5-HMAC, and Skipjack algorithms from /dev/crypto. 202 203r360557: 204 Remove support for DES, Triple DES, Blowfish, Cast, and 205 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC, 206 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4). 207 208r359945: 209 Remove support for Triple DES, Blowfish, and MD5 HMAC from 210 geli(4). 211 212r359786-r359787: 213 Remove support for DES, Triple DES, and RC4 from in-kernel GSS 214 authentication. 215 216r357627: 217 remove elf2aout. 218 219r357560-r357565: 220 init(8), service(8), and cron(8) will now adopt user/class environment 221 variables (excluding PATH, by default, which will be overwritten) by 222 default. Notably, environment variables for all cron jobs and rc 223 services can now be set via login.conf(5). 224 225r357455: 226 sparc64 has been removed from FreeBSD. 227 228r355677: 229 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes 230 (RFC-8276) to the NFS client and server. 231 NFSv4.2 is comprised of several optional features that can be supported 232 in addition to NFSv4.1. This patch adds the following optional features: 233 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED) 234 - posix_fallocate() 235 - intra server file range copying via the copy_file_range(2) syscall 236 --> Avoiding data tranfer over the wire to/from the NFS client. 237 - lseek(SEEK_DATA/SEEK_HOLE) 238 - Extended attribute syscalls for "user" namespace attributes as defined 239 by RFC-8276. 240 241 For the client, NFSv4.2 is only used if the mount command line option 242 minorversion=2 is specified. 243 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4 244 and vfs.nfsd.server_max_minorversion4 have been added that allow 245 sysadmins to limit the minor versions of NFSv4 supported by the nfsd 246 server. 247 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2 248 on the server. 249 250r356263: 251 armv5 support has been removed from FreeBSD. 252 253r354517: 254 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices. 255 256r354269: 257 sqlite3 is updated to sqlite3-3.30.1. 258 259r352668: 260 cron(8) now supports the -n (suppress mail on succesful run) and -q 261 (suppress logging of command execution) options in the crontab format. 262 See the crontab(5) manpage for details. 263 264r352304: 265 ntpd is no longer by default locked in memory. rlimit memlock 32 266 or rlimit memlock 0 can be used to restore this behaviour. 267 268r351863: 269 rc.subr(8) now honors ${name}_env in all rc(8) scripts. Previously, 270 environment variables set by a user via ${name}_env were ignored 271 if the service defined a custom *_cmd variable to control the behavior 272 of the run_rc_command function, e.g., start_cmd, instead of relying on 273 the variables like command and command_args, 274 275r351770,r352920,r352922,r352923: 276 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync, 277 and iflag=fullblock flags, compatible with illumos and GNU. 278 279r351522: 280 Add kernel-side support for in-kernel Transport Layer Security 281 (KTLS). KTLS permits using sendfile(2) over sockets using 282 TLS. 283 284r351397: 285 WPA is updated from 2.8 to 2.9. 286 287r351361: 288 Add probes for lockmgr(9) to the lockstat DTrace provider, add 289 corresponding lockstat(1) events, and document the new probes in 290 dtrace_lockstat.4. 291 292r351356: 293 Intel RST is a new 'feature' that remaps NVMe devices from 294 their normal location to part of the AHCI bar space. This 295 will eliminate the need to set the BIOS SATA setting from RST 296 to AHCI causing the nvme drive to be erased before FreeBSD 297 will see the nvme drive. FreeBSD will now be able to see the 298 nvme drive now in the default config. 299 300r351201, r351372: 301 Add a vop_stdioctl() call, so that file systems that do not support 302 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE). 303 The algorithm appears to be compatible with the POSIX draft and 304 the implementation in Linux for the case of a file system that 305 does not support holes. Prior to this patch, lseek(2) would reply 306 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in 307 file systems that do not support holes. 308 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for 309 any other cases, such as a ENOTTY return from vn_bmap_seekhole(). 310 311r350665: 312 The fuse driver has been renamed to fusefs(5) and been substantially 313 rewritten. The new driver includes many bug fixes and performance 314 enhancements, as well as the following user-visible features: 315 * Optional kernel-side permissions checks (-o default_permissions) 316 * mknod(2), socket(2), and pipe(2) support 317 * server side locking with fcntl(2) 318 * FUSE operations are now interruptible when mounted with -o intr 319 * server side handling of UTIME_NOW during utimensat(2) 320 * mount options may be updated with "mount -u" 321 * fusefs file system may now be exported over NFS 322 * RLIMIT_FSIZE support 323 * support for fuse file systems using protocols as old as 7.4 324 325 FUSE file system developers should also take note of the following new 326 features: 327 * The protocol level has been raised from 7.8 to 7.23 328 * kqueue support on /dev/fuse 329 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY 330 331r350471: 332 gnop(8) can now configure a delay to be applied to read and write 333 request delays. See the -d, -q and -x parameters. 334 335r350315, r350316: 336 Adds a Linux compatible copy_file_range(2) syscall. 337 338r350307: 339 libcap_random(3) has been removed. Applications can use native 340 APIs to get random data in capability mode. 341 342r349529,r349530: 343 Add support for using unmapped mbufs with sendfile(2). 344 345r349352: 346 nand(4) and related components have been removed. 347 348r349349: 349 The UEFI loader now supports HTTP boot. 350 351r349335: 352 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing 353 guests to play to and record audio data from the host. 354 355r349286: 356 swapon(8) can now erase a swap device immediately before enabling it, 357 similar to newfs(8)'s -E option. This behaviour can be specified by 358 adding -E to swapon(8)'s command-line parameters, or by adding the 359 "trimonce" option to a swap device's /etc/fstab entry. 360 361r347908-r347923: 362 The following network drivers have been removed: bm(4), cs(4), de(4), 363 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4), 364 vx(4), wb(4), xe(4). 365 366r347532: 367 Wired page accounting has been split into kernel wirings and user 368 wirings (e.g., by mlock(2)). Kernel wirings no long count towards 369 the global limit, which is renamed to vm.max_user_wired. bhyve -S 370 allocates user-wired memory and is now subject to that limit. 371 372$FreeBSD$ 373
