648176e095 bluetooth: Default to discoverable off
Try to not expose bluetooth devices to external devices unless the user
explicitly configures it, like any other radio/network device.  Bluetooth
has a long history of security problems and it is probably best to keep it
disabled if not needed.

Users who do use the bluetooth device should enable "discoverable" in
bluetooth.device.conf(5) after this change.

Keep in mind that bluetooth addresses can be discovered by passive
monitoring or whole address-space scans[0], so a safety conscious user
should also disable "connectable" in bluetooth.device.conf(5).

64a16434d8 Add support for compressed kernel dumps.
When using a kernel built with the GZIO config option, dumpon -z can be
used to configure gzip compression using the in-kernel copy of zlib.
This is useful on systems with large amounts of RAM, which require a
correspondingly large dump device. Recovery of compressed dumps is also
faster since fewer bytes need to be copied from the dump device.

Because we have no way of knowing the final size of a compressed dump
until it is written, the kernel will always attempt to dump when
compression is configured, regardless of the dump device size. If the
dump is aborted because we run out of space, an error is reported on
the console.

savecore(8) is modified to handle compressed dumps and save them to
vmcore.<index>.gz, as it does when given the -z option.

A new rc.conf variable, dumpon_flags, is added. Its value is added to
the boot-time dumpon(8) invocation that occurs when a dump device is
configured in rc.conf.

dde7644292 Anticongestion refinements for ntpd rc script. This reverts r324681
and checks if ntp leapfile needs fetching before entering into the
anticongestion sleep.

Unfortunately some ports still use their own sleeps so, this commit
doesn't address the complete problem which is compounded by every
port that uses its own anticongestion mechanism.

50e3590c44 Enhance mdmfs(8) to work with tmpfs(5).
Existing scripts and associated config such as rc.initdiskless, rc.d/var,
and others, use mdmfs to create memory filesystems. That program accepts a
size argument which allows SI suffixes and treats an unsuffixed number as a
count of 512 byte sectors. That makes it difficult to convert existing
scripts to use tmpfs instead of mdmfs, because tmpfs treats unsuffixed
numbers as a count of bytes. The script logic to deal with existing user
config that might include suffixed and unsuffixed numbers is... unpleasant.

Also, there is no g'tee that tmpfs will be available. It is sometimes
configured out of small-resource embedded systems to save memory and flash
storage space.

These changes enhance mdmfs(8) so that it accepts two new values for the
'md-device' arg: 'tmpfs' and 'auto'. With tmpfs, the program always uses
tmpfs(5) (and fails if it's not available). With 'auto' the program prefers
tmpfs, but falls back to using md(4) if tmpfs isn't available. It also
handles the -s <size> argument so that the mdconfig interpetation of
unsuffixed numbers applies when tmpfs is used as well, so that existing user
config keeps working after a switch to tmpfs.

A new rc setting, mfs_type, is added to etc/defaults/rc.conf to let users
force the use of tmpfs or md; the default value is "auto".

86571b9c01 Consolidate random sleeps in periodic scripts
Multiple periodic scripts sleep for a random amount of time in order to
mitigate the thundering herd problem. This is bad, because the sum of
multiple uniformly distributed random variables approaches a normal
distribution, so the problem isn't mitigated as effectively as it would be
with a single sleep.

This change creates a single configurable anticongestion sleep. periodic
will only sleep if at least one script requires it, and it will never sleep
more than once per invocation. It also won't sleep if periodic was run
interactively, fixing an unrelated longstanding bug.

480f31c214 Add support for encrypted kernel crash dumps.
Changes include modifications in kernel crash dump routines, dumpon(8) and
savecore(8). A new tool called decryptcore(8) was added.

A new DIOCSKERNELDUMP I/O control was added to send a kernel crash dump
configuration in the diocskerneldump_arg structure to the kernel.
The old DIOCSKERNELDUMP I/O control was renamed to DIOCSKERNELDUMP_FREEBSD11 for
backward ABI compatibility.

dumpon(8) generates an one-time random symmetric key and encrypts it using
an RSA public key in capability mode. Currently only AES-256-CBC is supported
but EKCD was designed to implement support for other algorithms in the future.
The public key is chosen using the -k flag. The dumpon rc(8) script can do this
automatically during startup using the dumppubkey rc.conf(5) variable.  Once the
keys are calculated dumpon sends them to the kernel via DIOCSKERNELDUMP I/O
control.

When the kernel receives the DIOCSKERNELDUMP I/O control it generates a random
IV and sets up the key schedule for the specified algorithm. Each time the
kernel tries to write a crash dump to the dump device, the IV is replaced by
a SHA-256 hash of the previous value. This is intended to make a possible
differential cryptanalysis harder since it is possible to write multiple crash
dumps without reboot by repeating the following commands:
# sysctl debug.kdb.enter=1
db> call doadump(0)
db> continue
# savecore

A kernel dump key consists of an algorithm identifier, an IV and an encrypted
symmetric key. The kernel dump key size is included in a kernel dump header.
The size is an unsigned 32-bit integer and it is aligned to a block size.
The header structure has 512 bytes to match the block size so it was required to
make a panic string 4 bytes shorter to add a new field to the header structure.
If the kernel dump key size in the header is nonzero it is assumed that the
kernel dump key is placed after the first header on the dump device and the core
dump is encrypted.

Separate functions were implemented to write the kernel dump header and the
kernel dump key as they need to be unencrypted. The dump_write function encrypts
data if the kernel was compiled with the EKCD option. Encrypted kernel textdumps
are not supported due to the way they are constructed which makes it impossible
to use the CBC mode for encryption. It should be also noted that textdumps don't
contain sensitive data by design as a user decides what information should be
dumped.

savecore(8) writes the kernel dump key to a key.# file if its size in the header
is nonzero. # is the number of the current core dump.

decryptcore(8) decrypts the core dump using a private RSA key and the kernel
dump key. This is performed by a child process in capability mode.
If the decryption was not successful the parent process removes a partially
decrypted core dump.

Description on how to encrypt crash dumps was added to the decryptcore(8),
dumpon(8), rc.conf(5) and savecore(8) manual pages.

EKCD was tested on amd64 using bhyve and i386, mipsel and sparc64 using QEMU.
The feature still has to be tested on arm and arm64 as it wasn't possible to run
FreeBSD due to the problems with QEMU emulation and lack of hardware.

630c9dba7a Enhance rc.d/netwait script to wait for late-attaching interfaces such as
USB NICs.

USB network hardware may not be enumerated and available when the rc.d
networking scripts run. Eventually the USB attachment completes and devd
events cause the network initialization to happen, but by then other rc.d
scripts have already failed, because services which depend on NETWORKING
(such as mountcritremote) may end up running before the network is actually
ready.

There is an existing netwait script, but because it is dependent on
NETWORKING it runs too late to prevent failure of some other rc
scripts. This change flips the order so that NETWORKING depends on netwait,
and netwait now depends on devd and routing (the former is needed to make
interfaces appear, and the latter is needed to run the ping tests in
netwait).

The netwait script used to be oriented primarily towards "as soon as any
host is reachable the network is fully functional", so you gave it a list of
IPs to try and you could optionally name an interface and it would wait for
carrier on that interface. That functionality still works the same, but now
you can provide a list of interfaces to wait for and it waits until each one
of them is available. The ping logic still completes as soon as the first IP
on the list responds.

These changes were submitted by Brenden Molloy <brendan+freebsd@bbqsrc.net>
in PR 205186, and lightly modified by me to allow a list of interfaces
instead of just one.

2a923f8f3c Rename etc/periodic/daily/430.status-rwho to periodic/daily/430.status-uptime
The command was checking local/remote system uptime, so rename the script to
match its function and to avoid confusion

The controlling variable in /etc/periodic.conf has been renamed from
daily_status_rwho_enable to daily_status_uptime_enable.

665aea9323 After r290196, the kernel won't wait for stuff like gmirror nodes
if they are not required for mounting rootfs.  However, it's possible
that some setups try to mount them in mountcritlocal (ie from fstab).

Export the list of current root mount holds using a new sysctl,
vfs.root_mount_hold, and make mountcritlocal retry if "mount -a" fails
and the list is not empty.

ebce46b2c6 Make rctl_enable rc variable actually work. To avoid breaking existing
setups that worked before, flip the default to "YES".  Most people don't
have /etc/rctl.conf, so they won't be affected in any way.

709c1a78cf Drop the default for performance_cx_lowest (ie, what to use when AC is connected) to ACPI C2.
ACPI C3 ends up doing a lot more work before entering sleep, some of which
requires grabbing a global ACPI hardware serialising mutex.

Because of this, the more CPU cores you have, the more that lock contends
under load, reaching close to the #1 lock contention (after VM, which is being
worked on.)

Tested:

* Sandy bridge Xeon, 2 socket * 8 core
* Ivy bridge Xeon v2, 2 socket * 8 core
* Westmere-EX, 4 socket * 10 core
* Ivybridge desktop
* Sandybridge mobile
* Ivybridge mobile

d2077b4e57 Allow additional flags to be passed to netstat -i in the daily status check.
In particular, this allows an administrator to specify "-h" for human
readable output if that is preferred.

The default setting passes "-d", so that can be excluded by using a custom
setting.
