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 138a04edfdcbd2: 14 Change the default minor version used for an NFSv4 mount 15 to the highest minor version supported by the NFSv4 server. 16 This default can be overridden by using the "minorversion" 17 mount option. 18 192c76eebca71b, 59f6f5e23c1a: 20 Add two daemons rpc.tlsclntd(8) and rpc.tlsservd(8) that provide 21 support for NFS-over-TLS as described in the Internet Draft titled 22 "Towards Remote Procedure Call Encryption By Default". 23 These daemons are only built when WITH_OPENSSL_KTLS is specified 24 and are only tested on amd64 at this time. 25 They use KTLS to encrypt/decrypt all NFS RPC message traffic, plus 26 optional verification of machine identity via X.509 certificates. 27 28f76393a6305b6: 29 Add AES-GCM support to armv8crypto(4) providing accelerated 30 support for KTLS, IPsec, and other crypto API consumers. 31 32074a91f746bd: 33 The aesni(4) and armv8crypto(4) devices are now included in 34 GENERIC on amd64, i386, and arm64. 35 362e1c94aa1fd5: 37 Add support for enforcing W^X mapping policy for user 38 processes. The policy is not enforced by default but can be 39 enabled by setting the kern.elf32.allow_wx and 40 kern.elf64.allow_wx sysctls to 0. Individual binaries can be 41 exempted from the policy by elfctl(1) via the wxneeded 42 feature. 43 444979620ece98: 45 Add AES-XTS support to armv8crypto(4) providing accelerated 46 software support for the default GELI cipher on arm64 systems. 47 48022ca2fc7fe0: 49 Add aio_writev(2) and aio_readv(2), vectored analogues of aio_write(2) 50 and aio_read(2). 51 5292bbfe1f0d1f: 53 The fusefs(5) protocol has been updated to 7.28. Support for 54 FUSE_COPY_FILE_RANGE and FUSE_LSEEK is added. 55 56r368667: 57 GDB 6.1.1 was removed. Users of crashinfo(8) should install the 58 gdb package or devel/gdb port. 59 60r368559: 61 The hme(4) driver was removed. 62 63r367660: 64 Fixes the case where gssd will not startup because /usr is a separate 65 local file system that is not yet mounted. It does not fix the case 66 where /usr is a separately mounted remote file system (such as NFS). 67 This latter case can be fixed by adding mountcritremote to the 68 REQUIRED line. Unfortunately doing so implies that all Kerberized 69 NFS mounts in /etc/fstab will need the "late" mount option. 70 This was not done, since the requirement for "late" would introduce 71 a POLA violation. 72 73r367423: 74 This commit added a new startup scripts variable called 75 nfsv4_server_only which uses the -R option on mountd added by r367026. 76 When nfsv4_server_only is set to "YES" in /etc/rc.conf, the NFS server 77 only handles NFSv4 and does not register with rpcbind. As such, rpcbind 78 does not need to be running. Useful for sites which consider rpcbind a 79 security issue. 80 81r366267: 82 Kernel option ACPI_DMAR was renamed to IOMMU. amd64's IOMMU subsystem 83 was split out from amd64 DMAR support and is now generic, i.e., it can 84 be used by all architectures. 85 86r364896: 87 A series of commits ending with r364896 added NFS over TLS 88 to the kernel. This is believed to be compatible with 89 the Internet Draft titled "Towards Remote Procedure Call Encryption 90 By Default" (expected to soon become an RFC). 91 The mount_nfs(8) and exports(5) man pages describe the mount and 92 export option(s) related to NFS over TLS. 93 For NFS over TLS to work, the rpctlscd(8) { client } or rpctlssd(8) 94 { server } must be running on a kernel built with "options KERN_TLS" 95 on an architecture where PMAP_HAS_DMAP != 0. 96 97r364725: 98 Changes to one obscure devd event generated on resume need to 99 be documented. The old form will still be generated in 13, but not 100 in 14. 101 102r363679: 103 Applications using regex(3), e.g. sed/grep, will no longer accept 104 redundant escapes for most ordinary characters. 105 106r363253: 107 SCTP support has been removed from GENERIC kernel configurations. 108 The SCTP stack is now built as sctp.ko and can be dynamically loaded. 109 110r363233: 111 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details. 112 113r363180: 114 The safexcel(4) crypto offload driver has been added. 115 116r363084: 117 nc(1) now implements SCTP mode, enabled by specifying the --sctp option. 118 119r362681: 120 A new implementation of bc and dc has been imported. It offers 121 better standards compliance, performance, localization and comes 122 with extensive test cases that are optionally installed. 123 Use WITHOUT_GH_BC=yes to build and install the world with the 124 previous version instead of the new one, if required. 125 126r362158, r362163: 127 struct export_args has changed so that the "user" specified for 128 the -maproot and -mapall exports(5) options may be in more than 129 16 groups. 130 131r361884: 132 sed(1) has learned about hex escapes (e.g. \x27) and will now do the 133 right thing with them, removing the need for printf magic or obnoxious 134 escaping in many scenarios. 135 136r361238, r361798, r361799: 137 ZFS will now unconditionally reject read(2) of a directory with EISDIR. 138 Additionally, read(2) of a directory is now rejected with EISDIR by 139 default and may be re-enabled for non-ZFS filesystems that allow it with 140 the sysctl(8) MIB 'security.bsd.allow_read_dir'. 141 142 Aliases for grep to default to '-d skip' may be desired if commonly 143 non-recursively grepping a list that includes directories and the 144 possibility of EISDIR errors in stderr is not tolerable. Example 145 aliases, commented out, have been installed in /root/.cshrc and 146 /root/.shrc. 147 148r361066: 149 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5). 150 exec.prepare runs before mounts, so can be used to populate new jails. 151 exec.release runs after unmounts, so can be used to remove ephemeral 152 jails. 153 154r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936: 155 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5, 156 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from 157 the kernel open cryptographic framework (OCF). 158 159r360562: 160 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, 161 MD5-HMAC, and Skipjack algorithms from /dev/crypto. 162 163r360557: 164 Remove support for DES, Triple DES, Blowfish, Cast, and 165 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC, 166 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4). 167 168r359945: 169 Remove support for Triple DES, Blowfish, and MD5 HMAC from 170 geli(4). 171 172r359786-r359787: 173 Remove support for DES, Triple DES, and RC4 from in-kernel GSS 174 authentication. 175 176r357627: 177 remove elf2aout. 178 179r357560-r357565: 180 init(8), service(8), and cron(8) will now adopt user/class environment 181 variables (excluding PATH, by default, which will be overwritten) by 182 default. Notably, environment variables for all cron jobs and rc 183 services can now be set via login.conf(5). 184 185r357455: 186 sparc64 has been removed from FreeBSD. 187 188r355677: 189 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes 190 (RFC-8276) to the NFS client and server. 191 NFSv4.2 is comprised of several optional features that can be supported 192 in addition to NFSv4.1. This patch adds the following optional features: 193 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED) 194 - posix_fallocate() 195 - intra server file range copying via the copy_file_range(2) syscall 196 --> Avoiding data tranfer over the wire to/from the NFS client. 197 - lseek(SEEK_DATA/SEEK_HOLE) 198 - Extended attribute syscalls for "user" namespace attributes as defined 199 by RFC-8276. 200 201 For the client, NFSv4.2 is only used if the mount command line option 202 minorversion=2 is specified. 203 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4 204 and vfs.nfsd.server_max_minorversion4 have been added that allow 205 sysadmins to limit the minor versions of NFSv4 supported by the nfsd 206 server. 207 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2 208 on the server. 209 210r356263: 211 armv5 support has been removed from FreeBSD. 212 213r354517: 214 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices. 215 216r354269: 217 sqlite3 is updated to sqlite3-3.30.1. 218 219r352668: 220 cron(8) now supports the -n (suppress mail on succesful run) and -q 221 (suppress logging of command execution) options in the crontab format. 222 See the crontab(5) manpage for details. 223 224r352304: 225 ntpd is no longer by default locked in memory. rlimit memlock 32 226 or rlimit memlock 0 can be used to restore this behaviour. 227 228r351863: 229 rc.subr(8) now honors ${name}_env in all rc(8) scripts. Previously, 230 environment variables set by a user via ${name}_env were ignored 231 if the service defined a custom *_cmd variable to control the behavior 232 of the run_rc_command function, e.g., start_cmd, instead of relying on 233 the variables like command and command_args, 234 235r351770,r352920,r352922,r352923: 236 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync, 237 and iflag=fullblock flags, compatible with illumos and GNU. 238 239r351522: 240 Add kernel-side support for in-kernel Transport Layer Security 241 (KTLS). KTLS permits using sendfile(2) over sockets using 242 TLS. 243 244r351397: 245 WPA is updated from 2.8 to 2.9. 246 247r351361: 248 Add probes for lockmgr(9) to the lockstat DTrace provider, add 249 corresponding lockstat(1) events, and document the new probes in 250 dtrace_lockstat.4. 251 252r351356: 253 Intel RST is a new 'feature' that remaps NVMe devices from 254 their normal location to part of the AHCI bar space. This 255 will eliminate the need to set the BIOS SATA setting from RST 256 to AHCI causing the nvme drive to be erased before FreeBSD 257 will see the nvme drive. FreeBSD will now be able to see the 258 nvme drive now in the default config. 259 260r351201, r351372: 261 Add a vop_stdioctl() call, so that file systems that do not support 262 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE). 263 The algorithm appears to be compatible with the POSIX draft and 264 the implementation in Linux for the case of a file system that 265 does not support holes. Prior to this patch, lseek(2) would reply 266 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in 267 file systems that do not support holes. 268 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for 269 any other cases, such as a ENOTTY return from vn_bmap_seekhole(). 270 271r350665: 272 The fuse driver has been renamed to fusefs(5) and been substantially 273 rewritten. The new driver includes many bug fixes and performance 274 enhancements, as well as the following user-visible features: 275 * Optional kernel-side permissions checks (-o default_permissions) 276 * mknod(2), socket(2), and pipe(2) support 277 * server side locking with fcntl(2) 278 * FUSE operations are now interruptible when mounted with -o intr 279 * server side handling of UTIME_NOW during utimensat(2) 280 * mount options may be updated with "mount -u" 281 * fusefs file system may now be exported over NFS 282 * RLIMIT_FSIZE support 283 * support for fuse file systems using protocols as old as 7.4 284 285 FUSE file system developers should also take note of the following new 286 features: 287 * The protocol level has been raised from 7.8 to 7.23 288 * kqueue support on /dev/fuse 289 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY 290 291r350471: 292 gnop(8) can now configure a delay to be applied to read and write 293 request delays. See the -d, -q and -x parameters. 294 295r350315, r350316: 296 Adds a Linux compatible copy_file_range(2) syscall. 297 298r350307: 299 libcap_random(3) has been removed. Applications can use native 300 APIs to get random data in capability mode. 301 302r349529,r349530: 303 Add support for using unmapped mbufs with sendfile(2). 304 305r349352: 306 nand(4) and related components have been removed. 307 308r349349: 309 The UEFI loader now supports HTTP boot. 310 311r349335: 312 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing 313 guests to play to and record audio data from the host. 314 315r349286: 316 swapon(8) can now erase a swap device immediately before enabling it, 317 similar to newfs(8)'s -E option. This behaviour can be specified by 318 adding -E to swapon(8)'s command-line parameters, or by adding the 319 "trimonce" option to a swap device's /etc/fstab entry. 320 321r347908-r347923: 322 The following network drivers have been removed: bm(4), cs(4), de(4), 323 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4), 324 vx(4), wb(4), xe(4). 325 326r347532: 327 Wired page accounting has been split into kernel wirings and user 328 wirings (e.g., by mlock(2)). Kernel wirings no long count towards 329 the global limit, which is renamed to vm.max_user_wired. bhyve -S 330 allocates user-wired memory and is now subject to that limit. 331 332$FreeBSD$ 333
