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