Prevent smack rules leaking during multi-app hybrid pkg uninstall
Package hybridity would be detected after database modifications and
change from 1 to 0 for the last application as a result, leading to
wrong process labels being considered (User::Pkg::$pkgName as opposed

Hybridity is now checked ahead of time to prevent the issue.

Move standard users group management from GUM to security-manager
Till now users created with "gum" tools were added
to predefined set of supplementary groups - audio,
display, video. This gave the users needed permissions
to access to various device nodes.
Unfortunately, this model does not work with multiple
"passwd/group" databases - /etc/{passwd,group} on read-only
storage, /opt/etc/{passwd,group} on read-writable storage.
This is because to assign user 'kitty' to the some system
group - defined in /etc/group, this file would need to be
modified, i.e.
video:x:44:media,system,multimedia_fw,owner,kitty
As noted - this can not be done because /opt/group is
supposed to be on read-only storage.
To address this issue security manager is used. It does
already provide NSS module which can assign logged in users
to predefined groups. The groups membership is based on
privileges assigned to given user type.
This commit:
- introduces three new privileges
- introduces mapping from new privileges to Unix groups
- assigns the new privileges to 'admin', 'normal', 'security',
'system' & 'guest' users
- adds the new privileges to global & local manifests

Lazily initialize variables that need tz-platform-config
Recent change in tz-platform-config made it use libc API for accessing
passwd/groups databases. As a result, each call to tz-platform-config will make
NSS load security-manager's NSS plugin with all dependent libraries initializing
their global variables.
The common library which is linked with nss plugin initializes two global
variables that use tz-platform-config which will lead to recursive call
prohibited by NSS.
This commit makes these variables lazily initialized to avoid the call to
tz-platform-config in security-manager's nss plugin initialization.

Attempt database fallback recovery on some schema errors
Done per HQ request for extra robustness in the face of unforeseen
database corruption.
Schema error detection amounts to preparing sqlite query templates. It
takes place at the end of database connection bringup (once the database
is verified to be up to date and passes integrity checks) by means of
calling sqlite3_prepare_v2 for every statement template ever to be used
at runtime. Sqlite statement compilation may fail due to lack of schema
compatibility. If such a failure occurs, fallback recovery is attempted
unless already tried.

Add database snapshotting and recovery
A snapshot of a working database can be established by running
security-manager-cmd --backup
This effectively copies "$TZ_SYS_DB/.security-manager.db" over
"$TZ_SYS_RO_SHARE/security-manager/.security-manager.db" (journal is not
being copied).
NOTE: backup does not check for concurrent access of the db file so the
user has to make sure no concurrent modification takes place in the
interim.
The manager performs an integrity check of the database at every startup
(see below). If the check fails, it truncates the database journal and
overwrites the database file with the latest snapshot, then reattempts
connection, migration and redoes the integrity check on the resulting
database.
As a first shot, integrity check uses the most aggressive possible form
achievable by sqlite pragmas by
* checking if the file exists (to prevent sqlite autovivifying it)
* checking 'pragma intergrity_check'
* checking 'pragma foreign_key_check'
TODO: for product acceptance, actual latency introduced by the integrity
check should be measured. If too high, the check can be made faster by
* dropping foreign_key_check
* replacing integrity_check with quick_check
To help make the decision, lax measurement were taken using
time sqlite3 >/dev/null /opt/dbspace/.security-manager.db 'pragma..'

Monitor mount/umount events on the system and update app mount namespaces
It is possible that file system path that has access guarded by a privilege
is not available when application starts, but becomes available later.
The reason for this is because a parent directory containing such path
may be a mount point that is not yet mounted at the time when application
starts.
If the application doesn't hold privilege to the directory in question,
it should have a dummy, empty directory mounted over that path. But this
cannot be done properly when application starts and the privileged directory
is not yet available.
Later, while application is running, the parent mount point may be mounted.
This mount will be propagated to mount namespaces of all running applications.
Then the applications that do not hold the required privilege will be able
to access privileged directory in that mount points, because dummy bind
mount wasn't done.
This patch implements a watcher keeping track of mount/unmount events in
the system. When such event is detected, mount namespaces of all running
applications will be reevaluated. If a privileged directory shows up in
mount namespace of an already running application and the application doesn't
hold required privilege, the directory will be hidden from the app.

client: do not add application process to hardcoded groups
Initial implementation of privilege enforcement with mount namespaces
included client code that added all application processes to hardcoded
set of groups: priv_externalstorage and priv_mediastorage.
This is wrong. Enforcement of privileges by either groups or mount
namespaces is to be configured in respectively privilege-group.list and
privilege-mount.list. Application process should be added to a group
if and only if it holds a privilege that is configured to be enforced
with a group. Similarly proper mounts and umounts will be done in application
mount namespace based on privilege status.
There is no need to hardcode groups. If a privilege is enforced with mount
namespace, it should not require additional group assignment. If it used
to be enforced with a group, but it has been switched to enforcement with
mount, filesystem permissions need to be adjusted, not security-manager code.
Privileges mediastorage and external storage are now enforced with bind
mounts. They are being removed from privilege-group mapping - combining
these two mechanisms is undesired.

Previous implementation of the method checking whether given source path

By careless pattern matching in /proc/self/mountinfo it could easily

New implementation relies on calling lstat() on both paths and comparing
results. If both paths have the same ID of containing device and the same
inode number, they are considered to be bind mounted.
