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 13f76393a6305b6: 14 Add AES-GCM support to armv8crypto(4) providing accelerated 15 support for KTLS, IPsec, and other crypto API consumers. 16 17074a91f746bd: 18 The aesni(4) and armv8crypto(4) devices are now included in 19 GENERIC on amd64, i386, and arm64. 20 212e1c94aa1fd5: 22 Add support for enforcing W^X mapping policy for user 23 processes. The policy is not enforced by default but can be 24 enabled by setting the kern.elf32.allow_wx and 25 kern.elf64.allow_wx sysctls to 0. Individual binaries can be 26 exempted from the policy by elfctl(1) via the wxneeded 27 feature. 28 294979620ece98: 30 Add AES-XTS support to armv8crypto(4) providing accelerated 31 software support for the default GELI cipher on arm64 systems. 32 33r368667: 34 GDB 6.1.1 was removed. Users of crashinfo(8) should install the 35 gdb package or devel/gdb port. 36 37r368559: 38 The hme(4) driver was removed. 39 40r367660: 41 Fixes the case where gssd will not startup because /usr is a separate 42 local file system that is not yet mounted. It does not fix the case 43 where /usr is a separately mounted remote file system (such as NFS). 44 This latter case can be fixed by adding mountcritremote to the 45 REQUIRED line. Unfortunately doing so implies that all Kerberized 46 NFS mounts in /etc/fstab will need the "late" mount option. 47 This was not done, since the requirement for "late" would introduce 48 a POLA violation. 49 50r367423: 51 This commit added a new startup scripts variable called 52 nfsv4_server_only which uses the -R option on mountd added by r367026. 53 When nfsv4_server_only is set to "YES" in /etc/rc.conf, the NFS server 54 only handles NFSv4 and does not register with rpcbind. As such, rpcbind 55 does not need to be running. Useful for sites which consider rpcbind a 56 security issue. 57 58r366267: 59 Kernel option ACPI_DMAR was renamed to IOMMU. amd64's IOMMU subsystem 60 was split out from amd64 DMAR support and is now generic, i.e., it can 61 be used by all architectures. 62 63r364896: 64 A series of commits ending with r364896 added NFS over TLS 65 to the kernel. This is believed to be compatible with 66 the Internet Draft titled "Towards Remote Procedure Call Encryption 67 By Default" (expected to soon become an RFC). 68 The mount_nfs(8) and exports(5) man pages describe the mount and 69 export option(s) related to NFS over TLS. 70 For NFS over TLS to work, the rpctlscd(8) { client } or rpctlssd(8) 71 { server } must be running on a kernel built with "options KERN_TLS" 72 on an architecture where PMAP_HAS_DMAP != 0. 73 74r364725: 75 Changes to one obscure devd event generated on resume need to 76 be documented. The old form will still be generated in 13, but not 77 in 14. 78 79r363679: 80 Applications using regex(3), e.g. sed/grep, will no longer accept 81 redundant escapes for most ordinary characters. 82 83r363253: 84 SCTP support has been removed from GENERIC kernel configurations. 85 The SCTP stack is now built as sctp.ko and can be dynamically loaded. 86 87r363233: 88 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details. 89 90r363180: 91 The safexcel(4) crypto offload driver has been added. 92 93r363084: 94 nc(1) now implements SCTP mode, enabled by specifying the --sctp option. 95 96r362681: 97 A new implementation of bc and dc has been imported. It offers 98 better standards compliance, performance, localization and comes 99 with extensive test cases that are optionally installed. 100 Use WITHOUT_GH_BC=yes to build and install the world with the 101 previous version instead of the new one, if required. 102 103r362158, r362163: 104 struct export_args has changed so that the "user" specified for 105 the -maproot and -mapall exports(5) options may be in more than 106 16 groups. 107 108r361884: 109 sed(1) has learned about hex escapes (e.g. \x27) and will now do the 110 right thing with them, removing the need for printf magic or obnoxious 111 escaping in many scenarios. 112 113r361238, r361798, r361799: 114 ZFS will now unconditionally reject read(2) of a directory with EISDIR. 115 Additionally, read(2) of a directory is now rejected with EISDIR by 116 default and may be re-enabled for non-ZFS filesystems that allow it with 117 the sysctl(8) MIB 'security.bsd.allow_read_dir'. 118 119 Aliases for grep to default to '-d skip' may be desired if commonly 120 non-recursively grepping a list that includes directories and the 121 possibility of EISDIR errors in stderr is not tolerable. Example 122 aliases, commented out, have been installed in /root/.cshrc and 123 /root/.shrc. 124 125r361066: 126 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5). 127 exec.prepare runs before mounts, so can be used to populate new jails. 128 exec.release runs after unmounts, so can be used to remove ephemeral 129 jails. 130 131r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936: 132 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5, 133 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from 134 the kernel open cryptographic framework (OCF). 135 136r360562: 137 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, 138 MD5-HMAC, and Skipjack algorithms from /dev/crypto. 139 140r360557: 141 Remove support for DES, Triple DES, Blowfish, Cast, and 142 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC, 143 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4). 144 145r359945: 146 Remove support for Triple DES, Blowfish, and MD5 HMAC from 147 geli(4). 148 149r359786-r359787: 150 Remove support for DES, Triple DES, and RC4 from in-kernel GSS 151 authentication. 152 153r357627: 154 remove elf2aout. 155 156r357560-r357565: 157 init(8), service(8), and cron(8) will now adopt user/class environment 158 variables (excluding PATH, by default, which will be overwritten) by 159 default. Notably, environment variables for all cron jobs and rc 160 services can now be set via login.conf(5). 161 162r357455: 163 sparc64 has been removed from FreeBSD. 164 165r355677: 166 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes 167 (RFC-8276) to the NFS client and server. 168 NFSv4.2 is comprised of several optional features that can be supported 169 in addition to NFSv4.1. This patch adds the following optional features: 170 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED) 171 - posix_fallocate() 172 - intra server file range copying via the copy_file_range(2) syscall 173 --> Avoiding data tranfer over the wire to/from the NFS client. 174 - lseek(SEEK_DATA/SEEK_HOLE) 175 - Extended attribute syscalls for "user" namespace attributes as defined 176 by RFC-8276. 177 178 For the client, NFSv4.2 is only used if the mount command line option 179 minorversion=2 is specified. 180 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4 181 and vfs.nfsd.server_max_minorversion4 have been added that allow 182 sysadmins to limit the minor versions of NFSv4 supported by the nfsd 183 server. 184 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2 185 on the server. 186 187r356263: 188 armv5 support has been removed from FreeBSD. 189 190r354517: 191 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices. 192 193r354269: 194 sqlite3 is updated to sqlite3-3.30.1. 195 196r352668: 197 cron(8) now supports the -n (suppress mail on succesful run) and -q 198 (suppress logging of command execution) options in the crontab format. 199 See the crontab(5) manpage for details. 200 201r352304: 202 ntpd is no longer by default locked in memory. rlimit memlock 32 203 or rlimit memlock 0 can be used to restore this behaviour. 204 205r351863: 206 rc.subr(8) now honors ${name}_env in all rc(8) scripts. Previously, 207 environment variables set by a user via ${name}_env were ignored 208 if the service defined a custom *_cmd variable to control the behavior 209 of the run_rc_command function, e.g., start_cmd, instead of relying on 210 the variables like command and command_args, 211 212r351770,r352920,r352922,r352923: 213 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync, 214 and iflag=fullblock flags, compatible with illumos and GNU. 215 216r351522: 217 Add kernel-side support for in-kernel Transport Layer Security 218 (KTLS). KTLS permits using sendfile(2) over sockets using 219 TLS. 220 221r351397: 222 WPA is updated from 2.8 to 2.9. 223 224r351361: 225 Add probes for lockmgr(9) to the lockstat DTrace provider, add 226 corresponding lockstat(1) events, and document the new probes in 227 dtrace_lockstat.4. 228 229r351356: 230 Intel RST is a new 'feature' that remaps NVMe devices from 231 their normal location to part of the AHCI bar space. This 232 will eliminate the need to set the BIOS SATA setting from RST 233 to AHCI causing the nvme drive to be erased before FreeBSD 234 will see the nvme drive. FreeBSD will now be able to see the 235 nvme drive now in the default config. 236 237r351201, r351372: 238 Add a vop_stdioctl() call, so that file systems that do not support 239 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE). 240 The algorithm appears to be compatible with the POSIX draft and 241 the implementation in Linux for the case of a file system that 242 does not support holes. Prior to this patch, lseek(2) would reply 243 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in 244 file systems that do not support holes. 245 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for 246 any other cases, such as a ENOTTY return from vn_bmap_seekhole(). 247 248r350665: 249 The fuse driver has been renamed to fusefs(5) and been substantially 250 rewritten. The new driver includes many bug fixes and performance 251 enhancements, as well as the following user-visible features: 252 * Optional kernel-side permissions checks (-o default_permissions) 253 * mknod(2), socket(2), and pipe(2) support 254 * server side locking with fcntl(2) 255 * FUSE operations are now interruptible when mounted with -o intr 256 * server side handling of UTIME_NOW during utimensat(2) 257 * mount options may be updated with "mount -u" 258 * fusefs file system may now be exported over NFS 259 * RLIMIT_FSIZE support 260 * support for fuse file systems using protocols as old as 7.4 261 262 FUSE file system developers should also take note of the following new 263 features: 264 * The protocol level has been raised from 7.8 to 7.23 265 * kqueue support on /dev/fuse 266 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY 267 268r350471: 269 gnop(8) can now configure a delay to be applied to read and write 270 request delays. See the -d, -q and -x parameters. 271 272r350315, r350316: 273 Adds a Linux compatible copy_file_range(2) syscall. 274 275r350307: 276 libcap_random(3) has been removed. Applications can use native 277 APIs to get random data in capability mode. 278 279r349529,r349530: 280 Add support for using unmapped mbufs with sendfile(2). 281 282r349352: 283 nand(4) and related components have been removed. 284 285r349349: 286 The UEFI loader now supports HTTP boot. 287 288r349335: 289 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing 290 guests to play to and record audio data from the host. 291 292r349286: 293 swapon(8) can now erase a swap device immediately before enabling it, 294 similar to newfs(8)'s -E option. This behaviour can be specified by 295 adding -E to swapon(8)'s command-line parameters, or by adding the 296 "trimonce" option to a swap device's /etc/fstab entry. 297 298r347908-r347923: 299 The following network drivers have been removed: bm(4), cs(4), de(4), 300 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4), 301 vx(4), wb(4), xe(4). 302 303r347532: 304 Wired page accounting has been split into kernel wirings and user 305 wirings (e.g., by mlock(2)). Kernel wirings no long count towards 306 the global limit, which is renamed to vm.max_user_wired. bhyve -S 307 allocates user-wired memory and is now subject to that limit. 308 309$FreeBSD$ 310
