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