03840eefd7 development(7): Replace "reboot" with "shutdown -r now"
We generally document shutdown(8) instead of reboot(8) as it's better for
interactive use.

In modern FreeBSD is matters a lot less, it's mostly just convention. One
minor thing is that shutdown(8) produces a global message, while reboot(8)
does not. It is believed that historically, some versions of reboot did not
do appropriate safe shutdown checks and just rebooted.

It's also just consistency: for example the handbook[1] documents shutdown.

There is actually another important difference between reboot and shutdown
-r now: reboot does not run /etc/rc.shutdown. This is because reboot has
its own shutdown procedure and does not signal init like init 6 and
shutdown -r now do (except in the case of rerooting via reboot -r).

A few years ago jilles@ proposed changing reboot's default to signalling
init (preserving reboot -q which just invokes the reboot system call), but
this was not accepted. Perhaps this can be tried again for 13.0.

1c4ca77890 Add d_off support for multiple filesystems.
The d_off field has been added to the dirent structure recently.
Currently filesystems don't support this feature.  Support has been
added and tested for zfs, ufs, ext2fs, fdescfs, msdosfs and unionfs.
A stub implementation is available for cd9660, nandfs, udf and
pseudofs but hasn't been tested.

Motivation for this feature: our usecase is for a userspace nfs server
(nfs-ganesha) with zfs.  At the moment we cache direntry offsets by
calling lseek once per entry, with this patch we can get the offset
directly from getdirentries(2) calls which provides a significant
speedup.

bf81eb3ca9 Add a WITH_BIND_NOW build knob
The linker's -z now flag sets the DF_BIND_NOW flag, which signals to the
runtime loader that all relocation processing should be performed at
process startup rather than on demand.  In combination with lld's
default of enabling relro this causes the GOT to be made read-only when
the process starts, preventing straightforward GOT overwrite attacks.

Shawn Webb discovered a failure on HardenedBSD with BIND_NOW and ifunc
use, which resulted in my rtld fix in r340137.  Add a BIND_NOW knob as
it is trivial to do so and is a useful ELF hardening feature.  This
change is equivalent to HardenedBSD's but not identical as there are
other diffs/conflicts nearby.

Note that our ELF Tool Chain readelf does not currently decode the
DF_BIND_NOW flag - see PR232983.

a594f9453b Make ng_pptpgre(8) netgraph node be able to restore order for packets
reordered in transit instead of dropping them altogether.
It uses sequence numbers of PPtPGRE packets.

A set of new sysctl(8) added to control this ability or disable it:

net.graph.pptpgre.reorder_max (1) defines maximum length of node's
private reorder queue used to keep data waiting for late packets.
Zero value disables reordering. Default value 1 allows the node to restore
the order for two packets swapped in transit. Greater values allow the node
to deliver packets being late after more packets in sequence
at cost of increased kernel memory usage.

net.graph.pptpgre.reorder_timeout (1) defines time value in miliseconds
used to wait for late packets. It may be useful to increase this
if reordering spot is distant.

d83db3fb6a Drop ed(1) "crypto"
You should not be using DES.  You should not have been using DES for the
past 30 years.

The ed DES-CBC scheme lacked several desirable properties of a sealed
document system, even ignoring DES itself.  In particular, it did not
provide the "integrity" cryptographic property (detection of tampering), and
it treated ASCII passwords as 64-bit keys (instead of using a KDF like
scrypt or PBKDF2).

Some general approaches ed(1) users might consider to replace the removed
DES mode:

1. Full disk encryption with something like AES-XTS.  This is easy to
conceptualize, design, and implement, and it provides confidentiality for
data at rest.  Like CBC, it lacks tampering protection.  Examples include
GELI, LUKS, FileVault2.

2. Encrypted overlay ("stackable") filesystems (EncFS, PEFS?, CryptoFS,
others).

3. Native encryption at the filesystem layer.  Ext4/F2FS, ZFS, APFS, and
NTFS all have some flavor of this.

4. Storing your files unencrypted.  It's not like DES was doing you much
good.

If you have DES-CBC scrambled files produced by ed(1) prior to this change,
you may decrypt them with:

  openssl des-cbc -d -iv 0 -K <key in hex> -in <inputfile> -out <plaintext>

This will enable callers to take const paths as part of syscall
decleration improvements.

Where doing so is easy and non-distruptive carry the const through
implementations. In UFS the value is passed to an interface that must
take non-const values. In ZFS, const poisoning would touch code shared
with upstream and it's not worth adding diffs.

Remove malloc_domain(9) and most other _domain KPIs added in r327900.
The new functions allow the caller to specify a general NUMA domain
selection policy, rather than specifically requesting an allocation from
a specific domain.  The latter policy tends to interact poorly with
M_WAITOK, resulting in situations where a caller is blocked indefinitely
because the specified domain is depleted.  Most existing consumers of
the _domain KPIs are converted to instead use a DOMAINSET_PREF() policy,
in which we fall back to other domains to satisfy the allocation
request.

This change also defines a set of DOMAINSET_FIXED() policies, which
only permit allocations from the specified domain.

43f75d57a2 Introduce an EXPERIMENTAL option for both src.conf(5) and the kernel.
In the last decade(s) we have seen both short term or long term projects
committed to the tree which were considered or even marked "experimental".
While out-of-tree development has become easier than it used to be in
CVS times, there still is a need to have the code shipping with HEAD but
not enabled by default.

While people may think about VIMAGE as one of the recent larger, long term
projects, early protocol implementations (before they are standardised)
are others.  (Free)BSD historically was one of the operating systems
which would have running code at early stages and help develop and
influence standardisation and the industry.

Give developers an opportunity to be more pro-active for early adoption
or running large scale code changes stumbling over each others but not
the user's feet.  I have not added the option to NOTES in order to avoid
breaking supported option builds, which require constant compile testing.
