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 13r363679: 14 Applications using regex(3), e.g. sed/grep, will no longer accept 15 redundant escapes for most ordinary characters. 16 17r363253: 18 SCTP support has been removed from GENERIC kernel configurations. 19 The SCTP stack is now built as sctp.ko and can be dynamically loaded. 20 21r363233: 22 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details. 23 24r363180: 25 The safexcel(4) crypto offload driver has been added. 26 27r363084: 28 nc(1) now implements SCTP mode, enabled by specifying the --sctp option. 29 30r362158, r362163: 31 struct export_args has changed so that the "user" specified for 32 the -maproot and -mapall exports(5) options may be in more than 33 16 groups. 34 35r361884: 36 sed(1) has learned about hex escapes (e.g. \x27) and will now do the 37 right thing with them, removing the need for printf magic or obnoxious 38 escaping in many scenarios. 39 40r361238, r361798, r361799: 41 ZFS will now unconditionally reject read(2) of a directory with EISDIR. 42 Additionally, read(2) of a directory is now rejected with EISDIR by 43 default and may be re-enabled for non-ZFS filesystems that allow it with 44 the sysctl(8) MIB 'security.bsd.allow_read_dir'. 45 46 Aliases for grep to default to '-d skip' may be desired if commonly 47 non-recursively grepping a list that includes directories and the 48 possibility of EISDIR errors in stderr is not tolerable. Example 49 aliases, commented out, have been installed in /root/.cshrc and 50 /root/.shrc. 51 52r361066: 53 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5). 54 exec.prepare runs before mounts, so can be used to populate new jails. 55 exec.release runs after unmounts, so can be used to remove ephemeral 56 jails. 57 58r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936: 59 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5, 60 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from 61 the kernel open cryptographic framework (OCF). 62 63r360562: 64 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, 65 MD5-HMAC, and Skipjack algorithms from /dev/crypto. 66 67r360557: 68 Remove support for DES, Triple DES, Blowfish, Cast, and 69 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC, 70 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4). 71 72r359945: 73 Remove support for Triple DES, Blowfish, and MD5 HMAC from 74 geli(4). 75 76r359786-r359787: 77 Remove support for DES, Triple DES, and RC4 from in-kernel GSS 78 authentication. 79 80r357627: 81 remove elf2aout. 82 83r357560-r357565: 84 init(8), service(8), and cron(8) will now adopt user/class environment 85 variables (excluding PATH, by default, which will be overwritten) by 86 default. Notably, environment variables for all cron jobs and rc 87 services can now be set via login.conf(5). 88 89r357455: 90 sparc64 has been removed from FreeBSD. 91 92r355677: 93 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes 94 (RFC-8276) to the NFS client and server. 95 NFSv4.2 is comprised of several optional features that can be supported 96 in addition to NFSv4.1. This patch adds the following optional features: 97 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED) 98 - posix_fallocate() 99 - intra server file range copying via the copy_file_range(2) syscall 100 --> Avoiding data tranfer over the wire to/from the NFS client. 101 - lseek(SEEK_DATA/SEEK_HOLE) 102 - Extended attribute syscalls for "user" namespace attributes as defined 103 by RFC-8276. 104 105 For the client, NFSv4.2 is only used if the mount command line option 106 minorversion=2 is specified. 107 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4 108 and vfs.nfsd.server_max_minorversion4 have been added that allow 109 sysadmins to limit the minor versions of NFSv4 supported by the nfsd 110 server. 111 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2 112 on the server. 113 114r356263: 115 armv5 support has been removed from FreeBSD. 116 117r354517: 118 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices. 119 120r354269: 121 sqlite3 is updated to sqlite3-3.30.1. 122 123r352668: 124 cron(8) now supports the -n (suppress mail on succesful run) and -q 125 (suppress logging of command execution) options in the crontab format. 126 See the crontab(5) manpage for details. 127 128r352304: 129 ntpd is no longer by default locked in memory. rlimit memlock 32 130 or rlimit memlock 0 can be used to restore this behaviour. 131 132r351770,r352920,r352922,r352923: 133 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync, 134 and iflag=fullblock flags, compatible with illumos and GNU. 135 136r351522: 137 Add kernel-side support for in-kernel Transport Layer Security 138 (KTLS). KTLS permits using sendfile(2) over sockets using 139 TLS. 140 141r351397: 142 WPA is updated from 2.8 to 2.9. 143 144r351361: 145 Add probes for lockmgr(9) to the lockstat DTrace provider, add 146 corresponding lockstat(1) events, and document the new probes in 147 dtrace_lockstat.4. 148 149r351356: 150 Intel RST is a new 'feature' that remaps NVMe devices from 151 their normal location to part of the AHCI bar space. This 152 will eliminate the need to set the BIOS SATA setting from RST 153 to AHCI causing the nvme drive to be erased before FreeBSD 154 will see the nvme drive. FreeBSD will now be able to see the 155 nvme drive now in the default config. 156 157r351201, r351372: 158 Add a vop_stdioctl() call, so that file systems that do not support 159 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE). 160 The algorithm appears to be compatible with the POSIX draft and 161 the implementation in Linux for the case of a file system that 162 does not support holes. Prior to this patch, lseek(2) would reply 163 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in 164 file systems that do not support holes. 165 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for 166 any other cases, such as a ENOTTY return from vn_bmap_seekhole(). 167 168r350665: 169 The fuse driver has been renamed to fusefs(5) and been substantially 170 rewritten. The new driver includes many bug fixes and performance 171 enhancements, as well as the following user-visible features: 172 * Optional kernel-side permissions checks (-o default_permissions) 173 * mknod(2), socket(2), and pipe(2) support 174 * server side locking with fcntl(2) 175 * FUSE operations are now interruptible when mounted with -o intr 176 * server side handling of UTIME_NOW during utimensat(2) 177 * mount options may be updated with "mount -u" 178 * fusefs file system may now be exported over NFS 179 * RLIMIT_FSIZE support 180 * support for fuse file systems using protocols as old as 7.4 181 182 FUSE file system developers should also take note of the following new 183 features: 184 * The protocol level has been raised from 7.8 to 7.23 185 * kqueue support on /dev/fuse 186 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY 187 188r350471: 189 gnop(8) can now configure a delay to be applied to read and write 190 request delays. See the -d, -q and -x parameters. 191 192r350315, r350316: 193 Adds a Linux compatible copy_file_range(2) syscall. 194 195r350307: 196 libcap_random(3) has been removed. Applications can use native 197 APIs to get random data in capability mode. 198 199r349529,r349530: 200 Add support for using unmapped mbufs with sendfile(2). 201 202r349352: 203 nand(4) and related components have been removed. 204 205r349349: 206 The UEFI loader now supports HTTP boot. 207 208r349335: 209 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing 210 guests to play to and record audio data from the host. 211 212r349286: 213 swapon(8) can now erase a swap device immediately before enabling it, 214 similar to newfs(8)'s -E option. This behaviour can be specified by 215 adding -E to swapon(8)'s command-line parameters, or by adding the 216 "trimonce" option to a swap device's /etc/fstab entry. 217 218r347908-r347923: 219 The following network drivers have been removed: bm(4), cs(4), de(4), 220 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4), 221 vx(4), wb(4), xe(4). 222 223r347532: 224 Wired page accounting has been split into kernel wirings and user 225 wirings (e.g., by mlock(2)). Kernel wirings no long count towards 226 the global limit, which is renamed to vm.max_user_wired. bhyve -S 227 allocates user-wired memory and is now subject to that limit. 228 229$FreeBSD$ 230
