for #14426.
In order to prevent import cycles and be able to use some type
definitions/constants I followed the same pattern we did for macOS by
creating a new package named `syncml`. This makes the changelog look
bigger than it actually is, so I split it into two commits to make it
easier to review:
-
[d7c233d](d7c233d54c)
moves the relevant bits to this new package
-
[7531a07](7531a0742b)
implements profile verification

for #11257, h/t to @mna for the idea of resetting `token_update_tally`.
this is to cover scenarios where a host might be re-enrolling (eg: the
device has been wiped) but we don't know about it.
since `TokenUpdate` might be called multiple times during the lifecycle
of an MDM enrollment, we add a check on the value of
`nano_enrollments.token_update_tally`. For the scenarios described
above, the tally is still `> 0` even thought the host is enrolling for
the first time.
to mitigate this, we reset its value to 0 when we receive an
`Authenticate` message (which only happens only per enrollment)
I set the value to `0` because it's incremented to `current_value+1` by
nanomdm before calling our handler.
for #10605, this modifies the cron used to ping the list/sync devices
API from ABM to account for the "deleted" and "modified" operation
types.
We know that:
1. Sometimes, Apple sends a "modified" operation type when a device's
MDM server is reassigned in ABM, up until now, we were ignoring these
devices.
2. Devices that are no longer assigned to Fleet in ABM can't be
migrated.

### What's happening
- Implemented the hashing mechanism defined by @mna in #10678, however
this mechanism is mainly relevant for batch profile updates via the CLI,
we can't leverage it when a host switches teams.
- Modified `BulkSetPendingMDMAppleHostProfiles` so when two profiles
with the same identifier are sheduled both for removal and update, the
function will now mark only the `install` as `pending` so it's picked by
the cron, and will `DELETE` the `remove` entry from the database so it's
not picked by the cron and never sent to the user.
- `GetHostMDMProfiles` and consequently the profiles returned in `GET
/api/_version_/fleet/hosts` return `host_mdm_apple_profiles.state =
NULL` as "Enforcing (pending", the distinction between `status =
'pending'` and `status IS NULL` is only useful for the cron, for users
both mean the same thing, and all our profile aggregations already
behave this way.
- Using the solution implemented by @gillespi314 in
https://github.com/fleetdm/fleet/pull/10998 we're now deleting the host
row from `host_disk_encryption_keys` if a host is moved from a team that
enforces disk encryption to a team that doesn't.

Related to #9459, this adds logic to the cron to add a
`com.fleetdm.fleetd.config` configuration profile to the
`apple_mdm_configuration_profiles` table.
As noted in the comments, this makes some assumptions:
- This profile will be applied to all hosts in the team (or "no team",)
but it will only be used by hosts that have a fleetd installation
without
an enroll secret and fleet URL (mainly DEP enrolled hosts).
- Once the profile is applied to a team (or "no team",) it's not removed
if
AppConfig.MDM.AppleBMDefaultTeam changes, this is to preserve existing
agents using the configuration (mainly ServerURL as EnrollSecret is used
only during enrollment)

#9132
The actual fix for the empty hosts is adding the `--database_path`
argument in the initial `osqueryd -S` invocation when retrieving the
UUID. Osquery attempts to retrieve the UUID from OS files/APIs, when not
possible (which is what happens on some linux distributions), then it
resorts to generating a new random UUID and storing it in the
`osquery.db`. The issue was Orbit's first invocation of `osqueryd -S`
was not using the same `osquery.db` as the main daemon invocation of
`osqueryd`.
I'm also adding a `hostname` + `platform` to the orbit enroll phase so
that if there are any issues in the future we can avoid the "empty" host
and have some information to help us troubleshoot.
## How to reproduce
On Linux, osquery reads `/sys/class/dmi/id/product_uuid` to load the
hardware UUID.
Some Linux distributions running on specific hardware or container
environments do not have such file available.
The way to reproduce on a Linux VM is to do the following:
```sh
$ sudo su
# chmod -r /sys/class/dmi/id/product_uuid
```
which will turn the file inaccessible to root.

Related to #9495, this adds the underlying methods to send a
configuration profile that enables FileVault and FileVault Escrow, so we
can fetch and decrypt the encryption key later on.
These methods still need to be called somewhere, and they might need to
be moved outside of `Service`, but at least this gives us a start.

The OVAL analyzer falsely assumes that any vulnerabilities detected on a
host only come from OVAL. However, it is possible that NVD detects
vulnerabilities on these hosts even though it excludes software from
deb_packages and rpm_packages. For example, a python package twisted
v22.20 has a vulnerability CVE-2022-39348 detected by NVD. The OVAL
analyzer would delete this vulnerability, and it would be re-inserted by
the NVD scanner on the next run. This creates a loop.
The fix is to only delete vulnerabilities that are actually detected
using OVAL. We already store this in the source column in the
software_cve table.

Feature: Improve our capability to detect vulnerable software on Ubuntu hosts
To improve the capability of detecting vulnerable software on Ubuntu, we are now using OVAL definitions to detect vulnerable software on Ubuntu hosts. If data sync is enabled (disable_data_sync=false) OVAL definitions are automatically kept up to date (they are 'refreshed' once per day) - there's also the option to manually download the OVAL definitions using the 'fleetctl vulnerability-data-stream' command. Downloaded definitions are then parsed into an intermediary format and then used to identify vulnerable software on Ubuntu hosts. Finally, any 'recent' detected vulnerabilities are sent to any third-party integrations.
not set on the INSERT.
- OUT: Only sets the ID on the passed session and returns it. (`CreatedAt`, `AccessedAt`, are not set.)
New version:
```go
func (ds *Datastore) NewSession(ctx context.Context, userID uint, sessionKey string) (*fleet.Session, error) {
sqlStatement := `
INSERT INTO sessions (
user_id,
` + "`key`" + `
)
VALUES(?,?)
`
result, err := ds.writer.ExecContext(ctx, sqlStatement, userID, sessionKey)
if err != nil {
return nil, ctxerr.Wrap(ctx, err, "inserting session")
}
id, _ := result.LastInsertId() // cannot fail with the mysql driver
return ds.sessionByID(ctx, ds.writer, uint(id))
}
```
- IN: Define arguments that are truly used when creating a session.
- OUT: Load and return the fleet.Session struct with all values set (using the `ds.writer` to support read replicas correctly).
PS: The new `NewSession` version mimics what we already do with other entities, like policies (`Datastore.NewGlobalPolicy`).
