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 13r352304: 14 ntpd is no longer by default locked in memory. rlimit memlock 32 15 or rlimit memlock 0 can be used to restore this behaviour. 16 17r351522: 18 Add kernel-side support for in-kernel Transport Layer Security 19 (KTLS). KTLS permits using sendfile(2) over sockets using 20 TLS. 21 22r351361: 23 Add probes for lockmgr(9) to the lockstat DTrace provider, add 24 corresponding lockstat(1) events, and document the new probes in 25 dtrace_lockstat.4. 26 27r351356: 28 Intel RST is a new 'feature' that remaps NVMe devices from 29 their normal location to part of the AHCI bar space. This 30 will eliminate the need to set the BIOS SATA setting from RST 31 to AHCI causing the nvme drive to be erased before FreeBSD 32 will see the nvme drive. FreeBSD will now be able to see the 33 nvme drive now in the default config. 34 35r351201, r351372: 36 Add a vop_stdioctl() call, so that file systems that do not support 37 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE). 38 The algorithm appears to be compatible with the POSIX draft and 39 the implementation in Linux for the case of a file system that 40 does not support holes. Prior to this patch, lseek(2) would reply 41 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in 42 file systems that do not support holes. 43 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for 44 any other cases, such as a ENOTTY return from vn_bmap_seekhole(). 45 46r350665: 47 The fuse driver has been renamed to fusefs(5) and been substantially 48 rewritten. The new driver includes many bug fixes and performance 49 enhancements, as well as the following user-visible features: 50 * Optional kernel-side permissions checks (-o default_permissions) 51 * mknod(2), socket(2), and pipe(2) support 52 * server side locking with fcntl(2) 53 * FUSE operations are now interruptible when mounted with -o intr 54 * server side handling of UTIME_NOW during utimensat(2) 55 * mount options may be updated with "mount -u" 56 * fusefs file system may now be exported over NFS 57 * RLIMIT_FSIZE support 58 * support for fuse file systems using protocols as old as 7.4 59 60 FUSE file system developers should also take note of the following new 61 features: 62 * The protocol level has been raised from 7.8 to 7.23 63 * kqueue support on /dev/fuse 64 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY 65 66r350471: 67 gnop(8) can now configure a delay to be applied to read and write 68 request delays. See the -d, -q and -x parameters. 69 70r350315, r350316: 71 Adds a Linux compatible copy_file_range(2) syscall. 72 73r350307: 74 libcap_random(3) has been removed. Applications can use native 75 APIs to get random data in capability mode. 76 77r349529,r349530: 78 Add support for using unmapped mbufs with sendfile(2). 79 80r349352: 81 nand(4) and related components have been removed. 82 83r349349: 84 The UEFI loader now supports HTTP boot. 85 86r349335: 87 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing 88 guests to play to and record audio data from the host. 89 90r349286: 91 swapon(8) can now erase a swap device immediately before enabling it, 92 similar to newfs(8)'s -E option. This behaviour can be specified by 93 adding -E to swapon(8)'s command-line parameters, or by adding the 94 "trimonce" option to a swap device's /etc/fstab entry. 95 96r347908-r347923: 97 The following network drivers have been removed: bm(4), cs(4), de(4), 98 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4), 99 vx(4), wb(4), xe(4). 100 101$FreeBSD$ 102
