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 13r363253: 14 SCTP support has been removed from GENERIC kernel configurations. 15 The SCTP stack is now built as sctp.ko and can be dynamically loaded. 16 17r363233: 18 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details. 19 20r363180: 21 The safexcel(4) crypto offload driver has been added. 22 23r363084: 24 nc(1) now implements SCTP mode, enabled by specifying the --sctp option. 25 26r362158, r362163: 27 struct export_args has changed so that the "user" specified for 28 the -maproot and -mapall exports(5) options may be in more than 29 16 groups. 30 31r361884: 32 sed(1) has learned about hex escapes (e.g. \x27) and will now do the 33 right thing with them, removing the need for printf magic or obnoxious 34 escaping in many scenarios. 35 36r361238, r361798, r361799: 37 ZFS will now unconditionally reject read(2) of a directory with EISDIR. 38 Additionally, read(2) of a directory is now rejected with EISDIR by 39 default and may be re-enabled for non-ZFS filesystems that allow it with 40 the sysctl(8) MIB 'security.bsd.allow_read_dir'. 41 42 Aliases for grep to default to '-d skip' may be desired if commonly 43 non-recursively grepping a list that includes directories and the 44 possibility of EISDIR errors in stderr is not tolerable. Example 45 aliases, commented out, have been installed in /root/.cshrc and 46 /root/.shrc. 47 48r361066: 49 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5). 50 exec.prepare runs before mounts, so can be used to populate new jails. 51 exec.release runs after unmounts, so can be used to remove ephemeral 52 jails. 53 54r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936: 55 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5, 56 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from 57 the kernel open cryptographic framework (OCF). 58 59r360562: 60 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, 61 MD5-HMAC, and Skipjack algorithms from /dev/crypto. 62 63r360557: 64 Remove support for DES, Triple DES, Blowfish, Cast, and 65 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC, 66 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4). 67 68r359945: 69 Remove support for Triple DES, Blowfish, and MD5 HMAC from 70 geli(4). 71 72r359786-r359787: 73 Remove support for DES, Triple DES, and RC4 from in-kernel GSS 74 authentication. 75 76r357627: 77 remove elf2aout. 78 79r357560-r357565: 80 init(8), service(8), and cron(8) will now adopt user/class environment 81 variables (excluding PATH, by default, which will be overwritten) by 82 default. Notably, environment variables for all cron jobs and rc 83 services can now be set via login.conf(5). 84 85r357455: 86 sparc64 has been removed from FreeBSD. 87 88r355677: 89 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes 90 (RFC-8276) to the NFS client and server. 91 NFSv4.2 is comprised of several optional features that can be supported 92 in addition to NFSv4.1. This patch adds the following optional features: 93 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED) 94 - posix_fallocate() 95 - intra server file range copying via the copy_file_range(2) syscall 96 --> Avoiding data tranfer over the wire to/from the NFS client. 97 - lseek(SEEK_DATA/SEEK_HOLE) 98 - Extended attribute syscalls for "user" namespace attributes as defined 99 by RFC-8276. 100 101 For the client, NFSv4.2 is only used if the mount command line option 102 minorversion=2 is specified. 103 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4 104 and vfs.nfsd.server_max_minorversion4 have been added that allow 105 sysadmins to limit the minor versions of NFSv4 supported by the nfsd 106 server. 107 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2 108 on the server. 109 110r356263: 111 armv5 support has been removed from FreeBSD. 112 113r354517: 114 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices. 115 116r354269: 117 sqlite3 is updated to sqlite3-3.30.1. 118 119r352668: 120 cron(8) now supports the -n (suppress mail on succesful run) and -q 121 (suppress logging of command execution) options in the crontab format. 122 See the crontab(5) manpage for details. 123 124r352304: 125 ntpd is no longer by default locked in memory. rlimit memlock 32 126 or rlimit memlock 0 can be used to restore this behaviour. 127 128r351770,r352920,r352922,r352923: 129 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync, 130 and iflag=fullblock flags, compatible with illumos and GNU. 131 132r351522: 133 Add kernel-side support for in-kernel Transport Layer Security 134 (KTLS). KTLS permits using sendfile(2) over sockets using 135 TLS. 136 137r351397: 138 WPA is updated from 2.8 to 2.9. 139 140r351361: 141 Add probes for lockmgr(9) to the lockstat DTrace provider, add 142 corresponding lockstat(1) events, and document the new probes in 143 dtrace_lockstat.4. 144 145r351356: 146 Intel RST is a new 'feature' that remaps NVMe devices from 147 their normal location to part of the AHCI bar space. This 148 will eliminate the need to set the BIOS SATA setting from RST 149 to AHCI causing the nvme drive to be erased before FreeBSD 150 will see the nvme drive. FreeBSD will now be able to see the 151 nvme drive now in the default config. 152 153r351201, r351372: 154 Add a vop_stdioctl() call, so that file systems that do not support 155 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE). 156 The algorithm appears to be compatible with the POSIX draft and 157 the implementation in Linux for the case of a file system that 158 does not support holes. Prior to this patch, lseek(2) would reply 159 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in 160 file systems that do not support holes. 161 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for 162 any other cases, such as a ENOTTY return from vn_bmap_seekhole(). 163 164r350665: 165 The fuse driver has been renamed to fusefs(5) and been substantially 166 rewritten. The new driver includes many bug fixes and performance 167 enhancements, as well as the following user-visible features: 168 * Optional kernel-side permissions checks (-o default_permissions) 169 * mknod(2), socket(2), and pipe(2) support 170 * server side locking with fcntl(2) 171 * FUSE operations are now interruptible when mounted with -o intr 172 * server side handling of UTIME_NOW during utimensat(2) 173 * mount options may be updated with "mount -u" 174 * fusefs file system may now be exported over NFS 175 * RLIMIT_FSIZE support 176 * support for fuse file systems using protocols as old as 7.4 177 178 FUSE file system developers should also take note of the following new 179 features: 180 * The protocol level has been raised from 7.8 to 7.23 181 * kqueue support on /dev/fuse 182 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY 183 184r350471: 185 gnop(8) can now configure a delay to be applied to read and write 186 request delays. See the -d, -q and -x parameters. 187 188r350315, r350316: 189 Adds a Linux compatible copy_file_range(2) syscall. 190 191r350307: 192 libcap_random(3) has been removed. Applications can use native 193 APIs to get random data in capability mode. 194 195r349529,r349530: 196 Add support for using unmapped mbufs with sendfile(2). 197 198r349352: 199 nand(4) and related components have been removed. 200 201r349349: 202 The UEFI loader now supports HTTP boot. 203 204r349335: 205 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing 206 guests to play to and record audio data from the host. 207 208r349286: 209 swapon(8) can now erase a swap device immediately before enabling it, 210 similar to newfs(8)'s -E option. This behaviour can be specified by 211 adding -E to swapon(8)'s command-line parameters, or by adding the 212 "trimonce" option to a swap device's /etc/fstab entry. 213 214r347908-r347923: 215 The following network drivers have been removed: bm(4), cs(4), de(4), 216 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4), 217 vx(4), wb(4), xe(4). 218 219r347532: 220 Wired page accounting has been split into kernel wirings and user 221 wirings (e.g., by mlock(2)). Kernel wirings no long count towards 222 the global limit, which is renamed to vm.max_user_wired. bhyve -S 223 allocates user-wired memory and is now subject to that limit. 224 225$FreeBSD$ 226
