Release notes for FreeBSD 13.0.
This file describes new user-visible features, changes and updates relevant to
users of binary FreeBSD releases. Each entry should describe the change in no
more than several sentences and should reference manual pages where an
interested user can find more information. Entries should wrap after 80
columns. Each entry should begin with one or more commit IDs on one line,
specified as a comma separated list and/or range, followed by a colon and a
newline. Entries should be separated by a newline.
Changes to this file should not be MFCed.
r351201:
Add a vop_stdioctl() call, so that file systems that do not support
holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
The algorithm appears to be compatible with the POSIX draft and
the implementation in Linux for the case of a file system that
does not support holes. Prior to this patch, lseek(2) would reply
-1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
file systems that do not support holes.
r350665:
The fuse driver has been renamed to fusefs(5) and been substantially
rewritten. The new driver includes many bug fixes and performance
enhancements, as well as the following user-visible features:
* Optional kernel-side permissions checks (-o default_permissions)
* mknod(2), socket(2), and pipe(2) support
* server side locking with fcntl(2)
* FUSE operations are now interruptible when mounted with -o intr
* server side handling of UTIME_NOW during utimensat(2)
* mount options may be updated with "mount -u"
* fusefs file system may now be exported over NFS
* RLIMIT_FSIZE support
* support for fuse file systems using protocols as old as 7.4
FUSE file system developers should also take note of the following new
features:
* The protocol level has been raised from 7.8 to 7.23
* kqueue support on /dev/fuse
* server-initiated cache invalidation via FUSE_NOTIFY_REPLY
r350471:
gnop(8) can now configure a delay to be applied to read and write
request delays. See the -d, -q and -x parameters.
r350315, r350316:
Adds a Linux compatible copy_file_range(2) syscall.
r350307:
libcap_random(3) has been removed. Applications can use native
APIs to get random data in capability mode.
r349352:
nand(4) and related components have been removed.
r349349:
The UEFI loader now supports HTTP boot.
r349335:
bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
guests to play to and record audio data from the host.
r349286:
swapon(8) can now erase a swap device immediately before enabling it,
similar to newfs(8)'s -E option. This behaviour can be specified by
adding -E to swapon(8)'s command-line parameters, or by adding the
"trimonce" option to a swap device's /etc/fstab entry.
r347908-r347923:
The following network drivers have been removed: bm(4), cs(4), de(4),
ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
vx(4), wb(4), xe(4).
