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 13r364725: 14 Changes to one obscure devd event generated on resume need to 15 be documented. The old form will still be generated in 13, but not 16 in 14. 17 18r363679: 19 Applications using regex(3), e.g. sed/grep, will no longer accept 20 redundant escapes for most ordinary characters. 21 22r363253: 23 SCTP support has been removed from GENERIC kernel configurations. 24 The SCTP stack is now built as sctp.ko and can be dynamically loaded. 25 26r363233: 27 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details. 28 29r363180: 30 The safexcel(4) crypto offload driver has been added. 31 32r363084: 33 nc(1) now implements SCTP mode, enabled by specifying the --sctp option. 34 35r362681: 36 A new implementation of bc and dc has been imported. It offers 37 better standards compliance, performance, localization and comes 38 with extensive test cases that are optionally installed. 39 Use WITHOUT_GH_BC=yes to build and install the world with the 40 previous version instead of the new one, if required. 41 42r362158, r362163: 43 struct export_args has changed so that the "user" specified for 44 the -maproot and -mapall exports(5) options may be in more than 45 16 groups. 46 47r361884: 48 sed(1) has learned about hex escapes (e.g. \x27) and will now do the 49 right thing with them, removing the need for printf magic or obnoxious 50 escaping in many scenarios. 51 52r361238, r361798, r361799: 53 ZFS will now unconditionally reject read(2) of a directory with EISDIR. 54 Additionally, read(2) of a directory is now rejected with EISDIR by 55 default and may be re-enabled for non-ZFS filesystems that allow it with 56 the sysctl(8) MIB 'security.bsd.allow_read_dir'. 57 58 Aliases for grep to default to '-d skip' may be desired if commonly 59 non-recursively grepping a list that includes directories and the 60 possibility of EISDIR errors in stderr is not tolerable. Example 61 aliases, commented out, have been installed in /root/.cshrc and 62 /root/.shrc. 63 64r361066: 65 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5). 66 exec.prepare runs before mounts, so can be used to populate new jails. 67 exec.release runs after unmounts, so can be used to remove ephemeral 68 jails. 69 70r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936: 71 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5, 72 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from 73 the kernel open cryptographic framework (OCF). 74 75r360562: 76 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, 77 MD5-HMAC, and Skipjack algorithms from /dev/crypto. 78 79r360557: 80 Remove support for DES, Triple DES, Blowfish, Cast, and 81 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC, 82 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4). 83 84r359945: 85 Remove support for Triple DES, Blowfish, and MD5 HMAC from 86 geli(4). 87 88r359786-r359787: 89 Remove support for DES, Triple DES, and RC4 from in-kernel GSS 90 authentication. 91 92r357627: 93 remove elf2aout. 94 95r357560-r357565: 96 init(8), service(8), and cron(8) will now adopt user/class environment 97 variables (excluding PATH, by default, which will be overwritten) by 98 default. Notably, environment variables for all cron jobs and rc 99 services can now be set via login.conf(5). 100 101r357455: 102 sparc64 has been removed from FreeBSD. 103 104r355677: 105 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes 106 (RFC-8276) to the NFS client and server. 107 NFSv4.2 is comprised of several optional features that can be supported 108 in addition to NFSv4.1. This patch adds the following optional features: 109 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED) 110 - posix_fallocate() 111 - intra server file range copying via the copy_file_range(2) syscall 112 --> Avoiding data tranfer over the wire to/from the NFS client. 113 - lseek(SEEK_DATA/SEEK_HOLE) 114 - Extended attribute syscalls for "user" namespace attributes as defined 115 by RFC-8276. 116 117 For the client, NFSv4.2 is only used if the mount command line option 118 minorversion=2 is specified. 119 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4 120 and vfs.nfsd.server_max_minorversion4 have been added that allow 121 sysadmins to limit the minor versions of NFSv4 supported by the nfsd 122 server. 123 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2 124 on the server. 125 126r356263: 127 armv5 support has been removed from FreeBSD. 128 129r354517: 130 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices. 131 132r354269: 133 sqlite3 is updated to sqlite3-3.30.1. 134 135r352668: 136 cron(8) now supports the -n (suppress mail on succesful run) and -q 137 (suppress logging of command execution) options in the crontab format. 138 See the crontab(5) manpage for details. 139 140r352304: 141 ntpd is no longer by default locked in memory. rlimit memlock 32 142 or rlimit memlock 0 can be used to restore this behaviour. 143 144r351770,r352920,r352922,r352923: 145 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync, 146 and iflag=fullblock flags, compatible with illumos and GNU. 147 148r351522: 149 Add kernel-side support for in-kernel Transport Layer Security 150 (KTLS). KTLS permits using sendfile(2) over sockets using 151 TLS. 152 153r351397: 154 WPA is updated from 2.8 to 2.9. 155 156r351361: 157 Add probes for lockmgr(9) to the lockstat DTrace provider, add 158 corresponding lockstat(1) events, and document the new probes in 159 dtrace_lockstat.4. 160 161r351356: 162 Intel RST is a new 'feature' that remaps NVMe devices from 163 their normal location to part of the AHCI bar space. This 164 will eliminate the need to set the BIOS SATA setting from RST 165 to AHCI causing the nvme drive to be erased before FreeBSD 166 will see the nvme drive. FreeBSD will now be able to see the 167 nvme drive now in the default config. 168 169r351201, r351372: 170 Add a vop_stdioctl() call, so that file systems that do not support 171 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE). 172 The algorithm appears to be compatible with the POSIX draft and 173 the implementation in Linux for the case of a file system that 174 does not support holes. Prior to this patch, lseek(2) would reply 175 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in 176 file systems that do not support holes. 177 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for 178 any other cases, such as a ENOTTY return from vn_bmap_seekhole(). 179 180r350665: 181 The fuse driver has been renamed to fusefs(5) and been substantially 182 rewritten. The new driver includes many bug fixes and performance 183 enhancements, as well as the following user-visible features: 184 * Optional kernel-side permissions checks (-o default_permissions) 185 * mknod(2), socket(2), and pipe(2) support 186 * server side locking with fcntl(2) 187 * FUSE operations are now interruptible when mounted with -o intr 188 * server side handling of UTIME_NOW during utimensat(2) 189 * mount options may be updated with "mount -u" 190 * fusefs file system may now be exported over NFS 191 * RLIMIT_FSIZE support 192 * support for fuse file systems using protocols as old as 7.4 193 194 FUSE file system developers should also take note of the following new 195 features: 196 * The protocol level has been raised from 7.8 to 7.23 197 * kqueue support on /dev/fuse 198 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY 199 200r350471: 201 gnop(8) can now configure a delay to be applied to read and write 202 request delays. See the -d, -q and -x parameters. 203 204r350315, r350316: 205 Adds a Linux compatible copy_file_range(2) syscall. 206 207r350307: 208 libcap_random(3) has been removed. Applications can use native 209 APIs to get random data in capability mode. 210 211r349529,r349530: 212 Add support for using unmapped mbufs with sendfile(2). 213 214r349352: 215 nand(4) and related components have been removed. 216 217r349349: 218 The UEFI loader now supports HTTP boot. 219 220r349335: 221 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing 222 guests to play to and record audio data from the host. 223 224r349286: 225 swapon(8) can now erase a swap device immediately before enabling it, 226 similar to newfs(8)'s -E option. This behaviour can be specified by 227 adding -E to swapon(8)'s command-line parameters, or by adding the 228 "trimonce" option to a swap device's /etc/fstab entry. 229 230r347908-r347923: 231 The following network drivers have been removed: bm(4), cs(4), de(4), 232 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4), 233 vx(4), wb(4), xe(4). 234 235r347532: 236 Wired page accounting has been split into kernel wirings and user 237 wirings (e.g., by mlock(2)). Kernel wirings no long count towards 238 the global limit, which is renamed to vm.max_user_wired. bhyve -S 239 allocates user-wired memory and is now subject to that limit. 240 241$FreeBSD$ 242
