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