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.

r352304:
|
|
ntpd is no longer by default locked in memory. rlimit memlock 32
|
|
or rlimit memlock 0 can be used to restore this behaviour.
|
|
|
|
r351522:
|
|
Add kernel-side support for in-kernel Transport Layer Security
|
|
(KTLS). KTLS permits using sendfile(2) over sockets using
|
|
TLS.
|
|
|
|
r351361:
|
|
Add probes for lockmgr(9) to the lockstat DTrace provider, add
|
|
corresponding lockstat(1) events, and document the new probes in
|
|
dtrace_lockstat.4.
|
|
|
|
r351356:
|
|
Intel RST is a new 'feature' that remaps NVMe devices from
|
|
their normal location to part of the AHCI bar space. This
|
|
will eliminate the need to set the BIOS SATA setting from RST
|
|
to AHCI causing the nvme drive to be erased before FreeBSD
|
|
will see the nvme drive. FreeBSD will now be able to see the
|
|
nvme drive now in the default config.
|
|
|
|
r351201, r351372:
|
|
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.
|
|
r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
|
|
any other cases, such as a ENOTTY return from vn_bmap_seekhole().
|
|
|
|
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.
|
|
|
|
r349529,r349530:
|
|
Add support for using unmapped mbufs with sendfile(2).
|
|
|
|
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).
