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