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