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 13r368667: 14 GDB 6.1.1 was removed. Users of crashinfo(8) should install the 15 gdb package or devel/gdb port. 16 17r368559: 18 The hme(4) driver was removed. 19 20r367660: 21 Fixes the case where gssd will not startup because /usr is a separate 22 local file system that is not yet mounted. It does not fix the case 23 where /usr is a separately mounted remote file system (such as NFS). 24 This latter case can be fixed by adding mountcritremote to the 25 REQUIRED line. Unfortunately doing so implies that all Kerberized 26 NFS mounts in /etc/fstab will need the "late" mount option. 27 This was not done, since the requirement for "late" would introduce 28 a POLA violation. 29 30r367423: 31 This commit added a new startup scripts variable called 32 nfsv4_server_only which uses the -R option on mountd added by r367026. 33 When nfsv4_server_only is set to "YES" in /etc/rc.conf, the NFS server 34 only handles NFSv4 and does not register with rpcbind. As such, rpcbind 35 does not need to be running. Useful for sites which consider rpcbind a 36 security issue. 37 38r366267: 39 Kernel option ACPI_DMAR was renamed to IOMMU. amd64's IOMMU subsystem 40 was split out from amd64 DMAR support and is now generic, i.e., it can 41 be used by all architectures. 42 43r364896: 44 A series of commits ending with r364896 added NFS over TLS 45 to the kernel. This is believed to be compatible with 46 the Internet Draft titled "Towards Remote Procedure Call Encryption 47 By Default" (expected to soon become an RFC). 48 The mount_nfs(8) and exports(5) man pages describe the mount and 49 export option(s) related to NFS over TLS. 50 For NFS over TLS to work, the rpctlscd(8) { client } or rpctlssd(8) 51 { server } must be running on a kernel built with "options KERN_TLS" 52 on an architecture where PMAP_HAS_DMAP != 0. 53 54r364725: 55 Changes to one obscure devd event generated on resume need to 56 be documented. The old form will still be generated in 13, but not 57 in 14. 58 59r363679: 60 Applications using regex(3), e.g. sed/grep, will no longer accept 61 redundant escapes for most ordinary characters. 62 63r363253: 64 SCTP support has been removed from GENERIC kernel configurations. 65 The SCTP stack is now built as sctp.ko and can be dynamically loaded. 66 67r363233: 68 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details. 69 70r363180: 71 The safexcel(4) crypto offload driver has been added. 72 73r363084: 74 nc(1) now implements SCTP mode, enabled by specifying the --sctp option. 75 76r362681: 77 A new implementation of bc and dc has been imported. It offers 78 better standards compliance, performance, localization and comes 79 with extensive test cases that are optionally installed. 80 Use WITHOUT_GH_BC=yes to build and install the world with the 81 previous version instead of the new one, if required. 82 83r362158, r362163: 84 struct export_args has changed so that the "user" specified for 85 the -maproot and -mapall exports(5) options may be in more than 86 16 groups. 87 88r361884: 89 sed(1) has learned about hex escapes (e.g. \x27) and will now do the 90 right thing with them, removing the need for printf magic or obnoxious 91 escaping in many scenarios. 92 93r361238, r361798, r361799: 94 ZFS will now unconditionally reject read(2) of a directory with EISDIR. 95 Additionally, read(2) of a directory is now rejected with EISDIR by 96 default and may be re-enabled for non-ZFS filesystems that allow it with 97 the sysctl(8) MIB 'security.bsd.allow_read_dir'. 98 99 Aliases for grep to default to '-d skip' may be desired if commonly 100 non-recursively grepping a list that includes directories and the 101 possibility of EISDIR errors in stderr is not tolerable. Example 102 aliases, commented out, have been installed in /root/.cshrc and 103 /root/.shrc. 104 105r361066: 106 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5). 107 exec.prepare runs before mounts, so can be used to populate new jails. 108 exec.release runs after unmounts, so can be used to remove ephemeral 109 jails. 110 111r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936: 112 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5, 113 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from 114 the kernel open cryptographic framework (OCF). 115 116r360562: 117 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, 118 MD5-HMAC, and Skipjack algorithms from /dev/crypto. 119 120r360557: 121 Remove support for DES, Triple DES, Blowfish, Cast, and 122 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC, 123 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4). 124 125r359945: 126 Remove support for Triple DES, Blowfish, and MD5 HMAC from 127 geli(4). 128 129r359786-r359787: 130 Remove support for DES, Triple DES, and RC4 from in-kernel GSS 131 authentication. 132 133r357627: 134 remove elf2aout. 135 136r357560-r357565: 137 init(8), service(8), and cron(8) will now adopt user/class environment 138 variables (excluding PATH, by default, which will be overwritten) by 139 default. Notably, environment variables for all cron jobs and rc 140 services can now be set via login.conf(5). 141 142r357455: 143 sparc64 has been removed from FreeBSD. 144 145r355677: 146 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes 147 (RFC-8276) to the NFS client and server. 148 NFSv4.2 is comprised of several optional features that can be supported 149 in addition to NFSv4.1. This patch adds the following optional features: 150 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED) 151 - posix_fallocate() 152 - intra server file range copying via the copy_file_range(2) syscall 153 --> Avoiding data tranfer over the wire to/from the NFS client. 154 - lseek(SEEK_DATA/SEEK_HOLE) 155 - Extended attribute syscalls for "user" namespace attributes as defined 156 by RFC-8276. 157 158 For the client, NFSv4.2 is only used if the mount command line option 159 minorversion=2 is specified. 160 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4 161 and vfs.nfsd.server_max_minorversion4 have been added that allow 162 sysadmins to limit the minor versions of NFSv4 supported by the nfsd 163 server. 164 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2 165 on the server. 166 167r356263: 168 armv5 support has been removed from FreeBSD. 169 170r354517: 171 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices. 172 173r354269: 174 sqlite3 is updated to sqlite3-3.30.1. 175 176r352668: 177 cron(8) now supports the -n (suppress mail on succesful run) and -q 178 (suppress logging of command execution) options in the crontab format. 179 See the crontab(5) manpage for details. 180 181r352304: 182 ntpd is no longer by default locked in memory. rlimit memlock 32 183 or rlimit memlock 0 can be used to restore this behaviour. 184 185r351863: 186 rc.subr(8) now honors ${name}_env in all rc(8) scripts. Previously, 187 environment variables set by a user via ${name}_env were ignored 188 if the service defined a custom *_cmd variable to control the behavior 189 of the run_rc_command function, e.g., start_cmd, instead of relying on 190 the variables like command and command_args, 191 192r351770,r352920,r352922,r352923: 193 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync, 194 and iflag=fullblock flags, compatible with illumos and GNU. 195 196r351522: 197 Add kernel-side support for in-kernel Transport Layer Security 198 (KTLS). KTLS permits using sendfile(2) over sockets using 199 TLS. 200 201r351397: 202 WPA is updated from 2.8 to 2.9. 203 204r351361: 205 Add probes for lockmgr(9) to the lockstat DTrace provider, add 206 corresponding lockstat(1) events, and document the new probes in 207 dtrace_lockstat.4. 208 209r351356: 210 Intel RST is a new 'feature' that remaps NVMe devices from 211 their normal location to part of the AHCI bar space. This 212 will eliminate the need to set the BIOS SATA setting from RST 213 to AHCI causing the nvme drive to be erased before FreeBSD 214 will see the nvme drive. FreeBSD will now be able to see the 215 nvme drive now in the default config. 216 217r351201, r351372: 218 Add a vop_stdioctl() call, so that file systems that do not support 219 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE). 220 The algorithm appears to be compatible with the POSIX draft and 221 the implementation in Linux for the case of a file system that 222 does not support holes. Prior to this patch, lseek(2) would reply 223 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in 224 file systems that do not support holes. 225 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for 226 any other cases, such as a ENOTTY return from vn_bmap_seekhole(). 227 228r350665: 229 The fuse driver has been renamed to fusefs(5) and been substantially 230 rewritten. The new driver includes many bug fixes and performance 231 enhancements, as well as the following user-visible features: 232 * Optional kernel-side permissions checks (-o default_permissions) 233 * mknod(2), socket(2), and pipe(2) support 234 * server side locking with fcntl(2) 235 * FUSE operations are now interruptible when mounted with -o intr 236 * server side handling of UTIME_NOW during utimensat(2) 237 * mount options may be updated with "mount -u" 238 * fusefs file system may now be exported over NFS 239 * RLIMIT_FSIZE support 240 * support for fuse file systems using protocols as old as 7.4 241 242 FUSE file system developers should also take note of the following new 243 features: 244 * The protocol level has been raised from 7.8 to 7.23 245 * kqueue support on /dev/fuse 246 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY 247 248r350471: 249 gnop(8) can now configure a delay to be applied to read and write 250 request delays. See the -d, -q and -x parameters. 251 252r350315, r350316: 253 Adds a Linux compatible copy_file_range(2) syscall. 254 255r350307: 256 libcap_random(3) has been removed. Applications can use native 257 APIs to get random data in capability mode. 258 259r349529,r349530: 260 Add support for using unmapped mbufs with sendfile(2). 261 262r349352: 263 nand(4) and related components have been removed. 264 265r349349: 266 The UEFI loader now supports HTTP boot. 267 268r349335: 269 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing 270 guests to play to and record audio data from the host. 271 272r349286: 273 swapon(8) can now erase a swap device immediately before enabling it, 274 similar to newfs(8)'s -E option. This behaviour can be specified by 275 adding -E to swapon(8)'s command-line parameters, or by adding the 276 "trimonce" option to a swap device's /etc/fstab entry. 277 278r347908-r347923: 279 The following network drivers have been removed: bm(4), cs(4), de(4), 280 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4), 281 vx(4), wb(4), xe(4). 282 283r347532: 284 Wired page accounting has been split into kernel wirings and user 285 wirings (e.g., by mlock(2)). Kernel wirings no long count towards 286 the global limit, which is renamed to vm.max_user_wired. bhyve -S 287 allocates user-wired memory and is now subject to that limit. 288 289$FreeBSD$ 290
