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