This functionality is turned on by default. It can be turned off with the
-R flag, but it is not recommended - if the underlying provider grows and
automatic expansion is turned off, it won't be possible to attach this
provider again, as the metadata is no longer located in the last sector.
If the automatic expansion is turned off and the underlying provider grows,
GELI will only log a message with the previous size of the provider, so

To use bectl in an example, when one creates a new boot environment with
either `bectl create <be>` or `bectl create -e <otherbe> <be>`, libbe will
take a snapshot of the original boot environment to clone. Previously, this
used %F-%T date format as the snapshot name, but this has some limitations-
attempting to create multiple boot environments in quick succession may
collide if done within the same second.
Tack a serial onto it to reduce the chances of a collision... we could still
collide if multiple processes/threads are creating boot environments at the
same time, but this is likely not a big concern as this has only been

The current approach of injecting manifest into mac_veriexec is to
verify the integrity of it in userspace (veriexec (8)) and pass its
entries into kernel using a char device (/dev/veriexec).
This requires verifying root partition integrity in loader,
for example by using memory disk and checking its hash.
Otherwise if rootfs is compromised an attacker could inject their own data.
This patch introduces an option to parse manifest in kernel based on envs.
The loader sets manifest path and digest.
EVENTHANDLER is used to launch the module right after the rootfs is mounted.
It has to be done this way, since one might want to verify integrity of the init file.
This means that manifest is required to be present on the root partition.
Note that the envs have to be set right before boot to make sure that no one can spoof them.

When a new client structure was allocated, it was added to the list
so that it was visible to other threads before the expiry time was
initialized, with only a single reference count.
The caller would increment the reference count, but it was possible
for another thread to decrement the reference count to zero and free
the structure before the caller incremented the reference count.
This could occur because the expiry time was still set to zero when
the new client structure was inserted in the list and the list was
unlocked.
This patch fixes the race by initializing the reference count to two
and initializing all fields, including the expiry time, before inserting
it in the list.

In particular:
- suspend the mount around vflush() to avoid new writes come after the
vnode is processed;
- flush pending metadata updates (mostly node times);
- remap all rw mappings of files from the mount into ro.
It is not clear to me how to handle writeable mappings on rw->ro for
tmpfs best. Other filesystems, which use vnode vm object, call
vgone() on vnodes with writers, which sets the vm object type to
OBJT_DEAD, and keep the resident pages and installed ptes as is. In
particular, the existing mappings continue to work as far as
application only accesses resident pages, but changes are not flushed
to file.
For tmpfs the vm object of VREG vnodes also serves as the data pages
container, giving single copy of the mapped pages, so it cannot be set
to OBJT_DEAD. Alternatives for making rw mappings ro could be either
invalidating them at all, or marking as CoW.

Summary:
OPAL needs to be kicked periodically in order for the firmware to make
progress on its tasks. To do so, create a heartbeat thread to perform this task
every N milliseconds, defined by the device tree. This task is also a central
location to handle all messages received from OPAL.

This change takes capsicum-test from upstream and applies some local changes to make the
tests work on FreeBSD when executed via Kyua.
The local modifications are as follows:
1. Make `OpenatTest.WithFlag` pass with the new dot-dot lookup behavior in FreeBSD 12.x+.
2. capsicum-test references a set of helper binaries: `mini-me`, `mini-me.noexec`, and
`mini-me.setuid`, as part of the execve/fexecve tests, via execve, fexecve, and open.
It achieves this upstream by assuming `mini-me*` is in the current directory, however,
in order for Kyua to execute `capsicum-test`, it needs to provide a full path to
`mini-me*`. In order to achieve this, I made `capsicum-test` cache the executable's
path from argv[0] in main(..) and use the cached value to compute the path to
`mini-me*` as part of the execve/fexecve testcases.
3. The capsicum-test test suite assumes that it's always being run on CAPABILITIES enabled
kernels. However, there's a chance that the test will be run on a host without a
CAPABILITIES enabled kernel, so we must check for the support before running the tests.
The way to achieve this is to add the relevant `feature_present("security_capabilities")`
check to SetupEnvironment::SetUp() and skip the tests when the support is not available.
While here, add a check for `kern.trap_enotcap` being enabled. As noted by markj@ in
https://github.com/google/capsicum-test/issues/23, this sysctl being enabled can trigger
non-deterministic failures. Therefore, the tests should be skipped if this sysctl is
enabled.
All local changes have been submitted to the capsicum-test project
(https://github.com/google/capsicum-test) and are in various stages of review.

Per the upstream pull-request [1]:
```
gtest prior to this change would completely ignore `GTEST_SKIP()` if
called in `Environment::SetUp()`, instead of bailing out early, unlike
`Test::SetUp()`, which would cause the tests themselves to be skipped.
The only way (prior to this change) to skip the tests would be to
trigger a fatal error via `GTEST_FAIL()`.
Desirable behavior, in this case, when dealing with
`Environment::SetUp()` is to check for prerequisites on a system
(example, kernel supports a particular featureset, e.g., capsicum), and
skip the tests. The alternatives prior to this change would be
undesirable:
- Failing sends the wrong message to the test user, as the result of the
tests is indeterminate, not failed.
- Having to add per-test class abstractions that override `SetUp()` to
test for the capsicum feature set, then skip all of the tests in their
respective SetUp fixtures, would be a lot of human and computational
work; checking for the feature would need to be done for all of the
tests, instead of once for all of the tests.
For those reasons, making `Environment::SetUp()` handle `GTEST_SKIP()`,
by not executing the testcases, is the most desirable solution.
In order to properly diagnose what happened when running the tests if
they are skipped, print out the diagnostics in an ad hoc manner.
Update the documentation to note this change and integrate a new test,
gtest_skip_in_environment_setup_test, into the test suite.
This change addresses #2189.

The goal with my merging in this change is to avoid requiring extensive
refactoring/retesting of test suites when ensuring prerequisites are met,
e.g., checking for a CAPABILITIES-enabled kernel before running capsicum-test
(see D19758 for more details).
The proof-of-concept is being imported before accepted by the upstream
project due to the fact that the upstream project is undergoing a potential
development freeze and the maintainers aren't responding to my PR.
