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 13r363679: 14 Applications using regex(3), e.g. sed/grep, will no longer accept 15 redundant escapes for most ordinary characters. 16 17r363253: 18 SCTP support has been removed from GENERIC kernel configurations. 19 The SCTP stack is now built as sctp.ko and can be dynamically loaded. 20 21r363233: 22 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details. 23 24r363180: 25 The safexcel(4) crypto offload driver has been added. 26 27r363084: 28 nc(1) now implements SCTP mode, enabled by specifying the --sctp option. 29 30r362681: 31 A new implementation of bc and dc has been imported. It offers 32 better standards compliance, performance, localization and comes 33 with extensive test cases that are optionally installed. 34 Use WITHOUT_GH_BC=yes to build and install the world with the 35 previous version instead of the new one, if required. 36 37r362158, r362163: 38 struct export_args has changed so that the "user" specified for 39 the -maproot and -mapall exports(5) options may be in more than 40 16 groups. 41 42r361884: 43 sed(1) has learned about hex escapes (e.g. \x27) and will now do the 44 right thing with them, removing the need for printf magic or obnoxious 45 escaping in many scenarios. 46 47r361238, r361798, r361799: 48 ZFS will now unconditionally reject read(2) of a directory with EISDIR. 49 Additionally, read(2) of a directory is now rejected with EISDIR by 50 default and may be re-enabled for non-ZFS filesystems that allow it with 51 the sysctl(8) MIB 'security.bsd.allow_read_dir'. 52 53 Aliases for grep to default to '-d skip' may be desired if commonly 54 non-recursively grepping a list that includes directories and the 55 possibility of EISDIR errors in stderr is not tolerable. Example 56 aliases, commented out, have been installed in /root/.cshrc and 57 /root/.shrc. 58 59r361066: 60 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5). 61 exec.prepare runs before mounts, so can be used to populate new jails. 62 exec.release runs after unmounts, so can be used to remove ephemeral 63 jails. 64 65r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936: 66 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5, 67 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from 68 the kernel open cryptographic framework (OCF). 69 70r360562: 71 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, 72 MD5-HMAC, and Skipjack algorithms from /dev/crypto. 73 74r360557: 75 Remove support for DES, Triple DES, Blowfish, Cast, and 76 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC, 77 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4). 78 79r359945: 80 Remove support for Triple DES, Blowfish, and MD5 HMAC from 81 geli(4). 82 83r359786-r359787: 84 Remove support for DES, Triple DES, and RC4 from in-kernel GSS 85 authentication. 86 87r357627: 88 remove elf2aout. 89 90r357560-r357565: 91 init(8), service(8), and cron(8) will now adopt user/class environment 92 variables (excluding PATH, by default, which will be overwritten) by 93 default. Notably, environment variables for all cron jobs and rc 94 services can now be set via login.conf(5). 95 96r357455: 97 sparc64 has been removed from FreeBSD. 98 99r355677: 100 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes 101 (RFC-8276) to the NFS client and server. 102 NFSv4.2 is comprised of several optional features that can be supported 103 in addition to NFSv4.1. This patch adds the following optional features: 104 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED) 105 - posix_fallocate() 106 - intra server file range copying via the copy_file_range(2) syscall 107 --> Avoiding data tranfer over the wire to/from the NFS client. 108 - lseek(SEEK_DATA/SEEK_HOLE) 109 - Extended attribute syscalls for "user" namespace attributes as defined 110 by RFC-8276. 111 112 For the client, NFSv4.2 is only used if the mount command line option 113 minorversion=2 is specified. 114 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4 115 and vfs.nfsd.server_max_minorversion4 have been added that allow 116 sysadmins to limit the minor versions of NFSv4 supported by the nfsd 117 server. 118 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2 119 on the server. 120 121r356263: 122 armv5 support has been removed from FreeBSD. 123 124r354517: 125 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices. 126 127r354269: 128 sqlite3 is updated to sqlite3-3.30.1. 129 130r352668: 131 cron(8) now supports the -n (suppress mail on succesful run) and -q 132 (suppress logging of command execution) options in the crontab format. 133 See the crontab(5) manpage for details. 134 135r352304: 136 ntpd is no longer by default locked in memory. rlimit memlock 32 137 or rlimit memlock 0 can be used to restore this behaviour. 138 139r351770,r352920,r352922,r352923: 140 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync, 141 and iflag=fullblock flags, compatible with illumos and GNU. 142 143r351522: 144 Add kernel-side support for in-kernel Transport Layer Security 145 (KTLS). KTLS permits using sendfile(2) over sockets using 146 TLS. 147 148r351397: 149 WPA is updated from 2.8 to 2.9. 150 151r351361: 152 Add probes for lockmgr(9) to the lockstat DTrace provider, add 153 corresponding lockstat(1) events, and document the new probes in 154 dtrace_lockstat.4. 155 156r351356: 157 Intel RST is a new 'feature' that remaps NVMe devices from 158 their normal location to part of the AHCI bar space. This 159 will eliminate the need to set the BIOS SATA setting from RST 160 to AHCI causing the nvme drive to be erased before FreeBSD 161 will see the nvme drive. FreeBSD will now be able to see the 162 nvme drive now in the default config. 163 164r351201, r351372: 165 Add a vop_stdioctl() call, so that file systems that do not support 166 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE). 167 The algorithm appears to be compatible with the POSIX draft and 168 the implementation in Linux for the case of a file system that 169 does not support holes. Prior to this patch, lseek(2) would reply 170 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in 171 file systems that do not support holes. 172 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for 173 any other cases, such as a ENOTTY return from vn_bmap_seekhole(). 174 175r350665: 176 The fuse driver has been renamed to fusefs(5) and been substantially 177 rewritten. The new driver includes many bug fixes and performance 178 enhancements, as well as the following user-visible features: 179 * Optional kernel-side permissions checks (-o default_permissions) 180 * mknod(2), socket(2), and pipe(2) support 181 * server side locking with fcntl(2) 182 * FUSE operations are now interruptible when mounted with -o intr 183 * server side handling of UTIME_NOW during utimensat(2) 184 * mount options may be updated with "mount -u" 185 * fusefs file system may now be exported over NFS 186 * RLIMIT_FSIZE support 187 * support for fuse file systems using protocols as old as 7.4 188 189 FUSE file system developers should also take note of the following new 190 features: 191 * The protocol level has been raised from 7.8 to 7.23 192 * kqueue support on /dev/fuse 193 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY 194 195r350471: 196 gnop(8) can now configure a delay to be applied to read and write 197 request delays. See the -d, -q and -x parameters. 198 199r350315, r350316: 200 Adds a Linux compatible copy_file_range(2) syscall. 201 202r350307: 203 libcap_random(3) has been removed. Applications can use native 204 APIs to get random data in capability mode. 205 206r349529,r349530: 207 Add support for using unmapped mbufs with sendfile(2). 208 209r349352: 210 nand(4) and related components have been removed. 211 212r349349: 213 The UEFI loader now supports HTTP boot. 214 215r349335: 216 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing 217 guests to play to and record audio data from the host. 218 219r349286: 220 swapon(8) can now erase a swap device immediately before enabling it, 221 similar to newfs(8)'s -E option. This behaviour can be specified by 222 adding -E to swapon(8)'s command-line parameters, or by adding the 223 "trimonce" option to a swap device's /etc/fstab entry. 224 225r347908-r347923: 226 The following network drivers have been removed: bm(4), cs(4), de(4), 227 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4), 228 vx(4), wb(4), xe(4). 229 230r347532: 231 Wired page accounting has been split into kernel wirings and user 232 wirings (e.g., by mlock(2)). Kernel wirings no long count towards 233 the global limit, which is renamed to vm.max_user_wired. bhyve -S 234 allocates user-wired memory and is now subject to that limit. 235 236$FreeBSD$ 237
