generates a configuration suitable for running unbound as a caching
forwarding resolver, and configures resolvconf(8) to update unbound's
list of forwarders in addition to /etc/resolv.conf. The initial list
is taken from the existing resolv.conf, which is rewritten to point to
localhost. Alternatively, a list of forwarders can be provided on the
command line.
To assist this script, add an rc.subr command called "enabled" which
does nothing except return 0 if the service is enabled and 1 if it is
not, without going through the usual checks. We should consider doing
the same for "status", which is currently pointless.
Add an rc script for unbound, called local_unbound. If there is no
configuration file, the rc script runs local-unbound-setup to generate
one.
Note that these scripts place the unbound configuration files in
/var/unbound rather than /etc/unbound. This is necessary so that
unbound can reload its configuration while chrooted. We should
probably provide symlinks in /etc.

This is a significant rewrite of much of the previous driver; lots of

descriptors to hold the frame
- Cleanup some of the offloading capabilities handling
As promised, drop the option to make the older GNU patch

GNU patch is still being built but something drastic may

There are now six additional variables
weekly_status_security_enable
weekly_status_security_inline
weekly_status_security_output
monthly_status_security_enable
monthly_status_security_inline
monthly_status_security_output
alongside their existing daily counterparts. They all have the same
default values.
All other "daily_status_security_${scriptname}_${whatever}"
variables have been renamed to "security_status_${name}_${whatever}".
A compatibility shim has been introduced for the old variable names,
which we will be able to remove in 11.0-RELEASE.
"security_status_${name}_enable" is still a boolean but a new
"security_status_${name}_period" allows to define the period of
each script. The value is one of "daily" (the default for backward
compatibility), "weekly", "monthly" and "NO".
Note that when the security periodic scripts are run directly from
crontab(5) (as opposed to being called by daily or weekly periodic
scripts), they will run unless the test is explicitely disabled with a
"NO", either for in the "_enable" or the "_period" variable.
When the security output is not inlined, the mail subject has been
changed from "$host $arg run output" to "$host $arg $period run output".
For instance:
myfbsd security run output -> myfbsd security daily run output
I don't think this is considered as a stable API, but feel free to
correct me if I'm wrong.
Finally, I will rearrange periodic.conf(5) and default/periodic.conf
to put the security options in their own section. I left them in

them are available (or registered), then system will default to

we fall back to the adaptor that's first on the list of registered
adaptors.
4) Introduce a way where RNGs can play a role of entropy source. This is
mostly useful for HW rngs.

configure sa(4) to request no I/O splitting by default.
For tape devices, the user needs to be able to clearly understand
what blocksize is actually being used when writing to a tape
device. The previous behavior of physio(9) was that it would split
up any I/O that was too large for the device, or too large to fit
into MAXPHYS. This means that if, for instance, the user wrote a
1MB block to a tape device, and MAXPHYS was 128KB, the 1MB write
would be split into 8 128K chunks. This would be done without
informing the user.
This has suboptimal effects, especially when trying to communicate
status to the user. In the event of an error writing to a tape
(e.g. physical end of tape) in the middle of a 1MB block that has
been split into 8 pieces, the user could have the first two 128K
pieces written successfully, the third returned with an error, and
the last 5 returned with 0 bytes written. If the user is using
a standard write(2) system call, all he will see is the ENOSPC
error. He won't have a clue how much actually got written. (With
a writev(2) system call, he should be able to determine how much
got written in addition to the error.)
The solution is to prevent physio(9) from splitting the I/O. The
new cdev flag, SI_NOSPLIT, tells physio that the driver does not
want I/O to be split beforehand.
Although the sa(4) driver now enables SI_NOSPLIT by default,
that can be disabled by two loader tunables for now. It will not
be configurable starting in FreeBSD 11.0. kern.cam.sa.allow_io_split
allows the user to configure I/O splitting for all sa(4) driver
instances. kern.cam.sa.%d.allow_io_split allows the user to
configure I/O splitting for a specific sa(4) instance.
There are also now three sa(4) driver sysctl variables that let the
users see some sa(4) driver values. kern.cam.sa.%d.allow_io_split
shows whether I/O splitting is turned on. kern.cam.sa.%d.maxio shows
the maximum I/O size allowed by kernel configuration parameters
(e.g. MAXPHYS, DFLTPHYS) and the capabilities of the controller.
kern.cam.sa.%d.cpi_maxio shows the maximum I/O size supported by
the controller.
Note that a better long term solution would be to implement support
for chaining buffers, so that that MAXPHYS is no longer a limiting
factor for I/O size to tape and disk devices. At that point, the
controller and the tape drive would become the limiting factors.
sys/conf.h: Add a new cdev flag, SI_NOSPLIT, that allows a
driver to tell physio not to split up I/O.
sys/param.h: Bump __FreeBSD_version to 1000049 for the addition
of the SI_NOSPLIT cdev flag.
kern_physio.c: If the SI_NOSPLIT flag is set on the cdev, return
any I/O that is larger than si_iosize_max or
MAXPHYS, has more than one segment, or would have
to be split because of misalignment with EFBIG.
(File too large).
In the event of an error, print a console message to
give the user a clue about what happened.
scsi_sa.c: Set the SI_NOSPLIT cdev flag on the devices created
for the sa(4) driver by default.
Add tunables to control whether we allow I/O splitting
in physio(9).
Explain in the comments that allowing I/O splitting
will be deprecated for the sa(4) driver in FreeBSD
11.0.
Add sysctl variables to display the maximum I/O
size we can do (which could be further limited by
read block limits) and the maximum I/O size that
the controller can do.
Limit our maximum I/O size (recorded in the cdev's
si_iosize_max) by MAXPHYS. This isn't strictly
necessary, because physio(9) will limit it to
MAXPHYS, but it will provide some clarity for the
application.
Record the controller's maximum I/O size reported
in the Path Inquiry CCB.
sa.4: Document the block size behavior, and explain that
the option of allowing physio(9) to split the I/O
will disappear in FreeBSD 11.0.

The old VPO_WANTED mechanism becames the hard-path for this new lock
and it becomes per-page rather than per-object.
The vm_object lock becames an interlock for this functionality:
it can be held in both read or write mode.
However, if the vm_object lock is held in read mode while acquiring
or releasing the busy state, the thread owner cannot make any
assumption on the busy state unless it is also busying it.
Also:
- Add a new flag to directly shared busy pages while vm_page_alloc
and vm_page_grab are being executed. This will be very helpful
once these functions happen under a read object lock.
- Move the swapping sleep into its own per-object flag
