13 0a6760a1de32, 3f3676a71266, 580c04df4db6:
17 Add support for the HiFive Unmatched RISC-V board.
20 Add a sysctl called vfs.nfsd.srvmaxio that can be used to
21 increase the NFS server's maximum I/O size from 128Kbytes
22 to any power of 2 up to 1Mbyte. It can only be set when
23 the nfsd threads are not running and will normally require
24 an increase in kern.ipc.maxsockbuf to at least the value
25 recommended by the console log message generated when
26 setting vfs.nfsd.srvmaxio is first attempted.
29 Add a new NFSv4.1/4.2 mount option "nconnect" that can
30 be used to specify the number of TCP connections that
31 will be used for the mount, up to a maximum of 16.
32 The first (default) TCP connection will be used for
33 all RPCs that consist of small RPC messages.
34 The RPCs that can consist of large RPC messages
35 (Read/Readdir/ReaddirPlus/Write) will be sent on the
36 additional TCP connections in a round robin fashion.
37 If either the NFS client or NFS server have multiple
38 network interfaces aggregated together or a network
39 interface that uses multiple queues, this can increase
40 NFS performance for the mount.
43 One True Awk has been updated to the latest from upstream
44 (20210215). All the FreeBSD patches, but one, have now been
45 either up streamed or discarded. Notable changes include:
46 o Locale is no longer used for ranges
48 o Better compatibility with gawk and mawk
50 The one FreeBSD change, likely to be removed in FreeBSD 14, is that
51 we still allow hex numbers, prefixed with 0x, to be parsed and
52 interpreted as hex numbers while all other awks (including one
53 true awk now) interpret them as 0 in line with awk's historic
57 Change the default minor version used for an NFSv4 mount
58 to the highest minor version supported by the NFSv4 server.
59 This default can be overridden by using the "minorversion"
62 2c76eebca71b, 59f6f5e23c1a:
63 Add two daemons rpc.tlsclntd(8) and rpc.tlsservd(8) that provide
64 support for NFS-over-TLS as described in the Internet Draft titled
65 "Towards Remote Procedure Call Encryption By Default".
66 These daemons are only built when WITH_OPENSSL_KTLS is specified
67 and are only tested on amd64 at this time.
68 They use KTLS to encrypt/decrypt all NFS RPC message traffic, plus
69 optional verification of machine identity via X.509 certificates.
72 Add AES-GCM support to armv8crypto(4) providing accelerated
73 support for KTLS, IPsec, and other crypto API consumers.
76 The aesni(4) and armv8crypto(4) devices are now included in
77 GENERIC on amd64, i386, and arm64.
80 Add support for enforcing W^X mapping policy for user
81 processes. The policy is not enforced by default but can be
82 enabled by setting the kern.elf32.allow_wx and
83 kern.elf64.allow_wx sysctls to 0. Individual binaries can be
84 exempted from the policy by elfctl(1) via the wxneeded
88 Add AES-XTS support to armv8crypto(4) providing accelerated
89 software support for the default GELI cipher on arm64 systems.
92 Add aio_writev(2) and aio_readv(2), vectored analogues of aio_write(2)
96 The fusefs(5) protocol has been updated to 7.28. Support for
97 FUSE_COPY_FILE_RANGE and FUSE_LSEEK is added.
100 GDB 6.1.1 was removed. Users of crashinfo(8) should install the
101 gdb package or devel/gdb port.
104 The hme(4) driver was removed.
107 Fixes the case where gssd will not startup because /usr is a separate
108 local file system that is not yet mounted. It does not fix the case
109 where /usr is a separately mounted remote file system (such as NFS).
110 This latter case can be fixed by adding mountcritremote to the
111 REQUIRED line. Unfortunately doing so implies that all Kerberized
112 NFS mounts in /etc/fstab will need the "late" mount option.
113 This was not done, since the requirement for "late" would introduce
117 This commit added a new startup scripts variable called
118 nfsv4_server_only which uses the -R option on mountd added by r367026.
119 When nfsv4_server_only is set to "YES" in /etc/rc.conf, the NFS server
120 only handles NFSv4 and does not register with rpcbind. As such, rpcbind
121 does not need to be running. Useful for sites which consider rpcbind a
125 Kernel option ACPI_DMAR was renamed to IOMMU. amd64's IOMMU subsystem
126 was split out from amd64 DMAR support and is now generic, i.e., it can
127 be used by all architectures.
130 A series of commits ending with r364896 added NFS over TLS
131 to the kernel. This is believed to be compatible with
132 the Internet Draft titled "Towards Remote Procedure Call Encryption
133 By Default" (expected to soon become an RFC).
134 The mount_nfs(8) and exports(5) man pages describe the mount and
135 export option(s) related to NFS over TLS.
136 For NFS over TLS to work, the rpctlscd(8) { client } or rpctlssd(8)
137 { server } must be running on a kernel built with "options KERN_TLS"
138 on an architecture where PMAP_HAS_DMAP != 0.
141 Changes to one obscure devd event generated on resume need to
142 be documented. The old form will still be generated in 13, but not
146 Applications using regex(3), e.g. sed/grep, will no longer accept
147 redundant escapes for most ordinary characters.
150 SCTP support has been removed from GENERIC kernel configurations.
151 The SCTP stack is now built as sctp.ko and can be dynamically loaded.
154 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details.
157 The safexcel(4) crypto offload driver has been added.
160 nc(1) now implements SCTP mode, enabled by specifying the --sctp option.
163 A new implementation of bc and dc has been imported. It offers
164 better standards compliance, performance, localization and comes
165 with extensive test cases that are optionally installed.
166 Use WITHOUT_GH_BC=yes to build and install the world with the
167 previous version instead of the new one, if required.
170 struct export_args has changed so that the "user" specified for
171 the -maproot and -mapall exports(5) options may be in more than
175 sed(1) has learned about hex escapes (e.g. \x27) and will now do the
176 right thing with them, removing the need for printf magic or obnoxious
177 escaping in many scenarios.
179 r361238, r361798, r361799:
180 ZFS will now unconditionally reject read(2) of a directory with EISDIR.
181 Additionally, read(2) of a directory is now rejected with EISDIR by
182 default and may be re-enabled for non-ZFS filesystems that allow it with
183 the sysctl(8) MIB 'security.bsd.allow_read_dir'.
185 Aliases for grep to default to '-d skip' may be desired if commonly
186 non-recursively grepping a list that includes directories and the
187 possibility of EISDIR errors in stderr is not tolerable. Example
188 aliases, commented out, have been installed in /root/.cshrc and
192 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5).
193 exec.prepare runs before mounts, so can be used to populate new jails.
194 exec.release runs after unmounts, so can be used to remove ephemeral
197 r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936:
198 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5,
199 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from
200 the kernel open cryptographic framework (OCF).
203 Remove support for ARC4, Blowfish, Cast, DES, Triple DES,
204 MD5-HMAC, and Skipjack algorithms from /dev/crypto.
207 Remove support for DES, Triple DES, Blowfish, Cast, and
208 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC,
209 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4).
212 Remove support for Triple DES, Blowfish, and MD5 HMAC from
216 Remove support for DES, Triple DES, and RC4 from in-kernel GSS
223 init(8), service(8), and cron(8) will now adopt user/class environment
224 variables (excluding PATH, by default, which will be overwritten) by
225 default. Notably, environment variables for all cron jobs and rc
226 services can now be set via login.conf(5).
229 sparc64 has been removed from FreeBSD.
232 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
233 (RFC-8276) to the NFS client and server.
234 NFSv4.2 is comprised of several optional features that can be supported
235 in addition to NFSv4.1. This patch adds the following optional features:
236 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
238 - intra server file range copying via the copy_file_range(2) syscall
239 --> Avoiding data tranfer over the wire to/from the NFS client.
240 - lseek(SEEK_DATA/SEEK_HOLE)
241 - Extended attribute syscalls for "user" namespace attributes as defined
244 For the client, NFSv4.2 is only used if the mount command line option
245 minorversion=2 is specified.
246 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
247 and vfs.nfsd.server_max_minorversion4 have been added that allow
248 sysadmins to limit the minor versions of NFSv4 supported by the nfsd
250 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
254 armv5 support has been removed from FreeBSD.
257 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
260 sqlite3 is updated to sqlite3-3.30.1.
263 cron(8) now supports the -n (suppress mail on succesful run) and -q
264 (suppress logging of command execution) options in the crontab format.
265 See the crontab(5) manpage for details.
268 ntpd is no longer by default locked in memory. rlimit memlock 32
269 or rlimit memlock 0 can be used to restore this behaviour.
272 rc.subr(8) now honors ${name}_env in all rc(8) scripts. Previously,
273 environment variables set by a user via ${name}_env were ignored
274 if the service defined a custom *_cmd variable to control the behavior
275 of the run_rc_command function, e.g., start_cmd, instead of relying on
276 the variables like command and command_args,
278 r351770,r352920,r352922,r352923:
279 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync,
280 and iflag=fullblock flags, compatible with illumos and GNU.
283 Add kernel-side support for in-kernel Transport Layer Security
284 (KTLS). KTLS permits using sendfile(2) over sockets using
288 WPA is updated from 2.8 to 2.9.
291 Add probes for lockmgr(9) to the lockstat DTrace provider, add
292 corresponding lockstat(1) events, and document the new probes in
296 Intel RST is a new 'feature' that remaps NVMe devices from
297 their normal location to part of the AHCI bar space. This
298 will eliminate the need to set the BIOS SATA setting from RST
299 to AHCI causing the nvme drive to be erased before FreeBSD
300 will see the nvme drive. FreeBSD will now be able to see the
301 nvme drive now in the default config.
304 Add a vop_stdioctl() call, so that file systems that do not support
305 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
306 The algorithm appears to be compatible with the POSIX draft and
307 the implementation in Linux for the case of a file system that
308 does not support holes. Prior to this patch, lseek(2) would reply
309 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
310 file systems that do not support holes.
311 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
312 any other cases, such as a ENOTTY return from vn_bmap_seekhole().
315 The fuse driver has been renamed to fusefs(5) and been substantially
316 rewritten. The new driver includes many bug fixes and performance
317 enhancements, as well as the following user-visible features:
318 * Optional kernel-side permissions checks (-o default_permissions)
319 * mknod(2), socket(2), and pipe(2) support
320 * server side locking with fcntl(2)
321 * FUSE operations are now interruptible when mounted with -o intr
322 * server side handling of UTIME_NOW during utimensat(2)
323 * mount options may be updated with "mount -u"
324 * fusefs file system may now be exported over NFS
325 * RLIMIT_FSIZE support
326 * support for fuse file systems using protocols as old as 7.4
328 FUSE file system developers should also take note of the following new
330 * The protocol level has been raised from 7.8 to 7.23
331 * kqueue support on /dev/fuse
332 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY
335 gnop(8) can now configure a delay to be applied to read and write
336 request delays. See the -d, -q and -x parameters.
339 Adds a Linux compatible copy_file_range(2) syscall.
342 libcap_random(3) has been removed. Applications can use native
343 APIs to get random data in capability mode.
346 Add support for using unmapped mbufs with sendfile(2).
349 nand(4) and related components have been removed.
352 The UEFI loader now supports HTTP boot.
355 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
356 guests to play to and record audio data from the host.
359 swapon(8) can now erase a swap device immediately before enabling it,
360 similar to newfs(8)'s -E option. This behaviour can be specified by
361 adding -E to swapon(8)'s command-line parameters, or by adding the
362 "trimonce" option to a swap device's /etc/fstab entry.
365 The following network drivers have been removed: bm(4), cs(4), de(4),
366 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
370 Wired page accounting has been split into kernel wirings and user
371 wirings (e.g., by mlock(2)). Kernel wirings no long count towards
372 the global limit, which is renamed to vm.max_user_wired. bhyve -S
373 allocates user-wired memory and is now subject to that limit.
