Subject: [PATCH] OCI: extract appstream data for runtimes
Runtimes also have appstream data - with description, license information,
and so forth, so we should extract the appstream data from the index
for refs that start with runtime/ as well.

Subject: [PATCH 01/10] common: Add a backport of
G_DBUS_METHOD_INVOCATION_HANDLED
This is syntactic sugar added in GLib 2.67.0, which makes it more clearly
correct when we return TRUE after a GDBus error.

Subject: [PATCH 02/10] run: Convert all environment variables into bwrap
arguments
This avoids some of them being filtered out by a setuid bwrap. It also
means that if they came from an untrusted source, they cannot be used
to inject arbitrary code into a non-setuid bwrap via mechanisms like
LD_PRELOAD.
Because they get bundled into a memfd or temporary file, they do not
actually appear in argv, ensuring that they remain inaccessible to
processes running under a different uid (which is important if their
values are tokens or other secrets).

Subject: [PATCH 03/10] tests: Expand coverage for environment variable
overrides
This checks that `flatpak run --env=` takes precedence over
`flatpak override --env=`, and that environment variables don't get
onto the bwrap command-line (which would be information disclosure
if their values are secret).

Subject: [PATCH 05/10] portal: Convert --env in extra-args into --env-fd
This hides overridden variables from the command-line, which means
processes running under other uids can't see them in /proc/*/cmdline,
which might be important if they contain secrets.

Subject: [PATCH 07/10] portal: Do not use caller-supplied variables in
environment
If the caller specifies a variable that can be used to inject arbitrary
code into processes, we must not allow it to enter the environment
block used to run `flatpak run`, which runs unsandboxed.
This change requires the previous commit "context: Add --env-fd option",
which adds infrastructure used here.
To be secure, this change also requires the previous commit
"run: Convert all environment variables into bwrap arguments", which
protects a non-setuid bwrap(1) from the same attack.

Subject: [PATCH 08/10] tests: Assert that --env= does not go in `flatpak run`
or bwrap environ
For the portal's use of --env-fd= to be safe, we want the environment
variables that it sets to end up in the environment for the program
that is run by `bwrap` as process 2, but they must not go into the
environment that gets used to run `flatpak run` or `bwrap`. Assert
that this is the case.
For completeness, we're testing both --env= and --env-fd= here,
even though the earlier commit
"portal: Do not use caller-supplied variables in environment"
always uses --env-fd=.

Subject: [PATCH 09/10] build: Convert environment into a sequence of bwrap
arguments
This means we can systematically pass the environment variables
through bwrap(1), even if it is setuid and thus is filtering out
security-sensitive environment variables. bwrap itself ends up being
run with an empty environment instead.
This fixes a regression when CVE-2021-21261 was fixed: before the
CVE fixes, LD_LIBRARY_PATH would have been passed through like this
and appeared in the `flatpak build` shell, but during the CVE fixes,
the special case that protected LD_LIBRARY_PATH was removed in favour
of the more general flatpak_bwrap_envp_to_args(). That reasoning only
works if we use flatpak_bwrap_envp_to_args(), consistently, everywhere
that we run the potentially-setuid bwrap.
Fixes: 6d1773d2 "run: Convert all environment variables into bwrap arguments"

Subject: [PATCH 4/7] oci: Set token on child oci registry and pass to
system-helper
When we create a system child registry we also set the current token on
it. This is not used directly in the client, however its saved in a
file called .token and re-read in the system-helper, allowing it to
also do the remote registry operations it needs to verify the child
registry.

Subject: [PATCH] build: Convert environment into a sequence of bwrap arguments
This means we can systematically pass the environment variables
through bwrap(1), even if it is setuid and thus is filtering out
security-sensitive environment variables. bwrap itself ends up being
run with an empty environment instead.
This fixes a regression when CVE-2021-21261 was fixed: before the
CVE fixes, LD_LIBRARY_PATH would have been passed through like this
and appeared in the `flatpak build` shell, but during the CVE fixes,
the special case that protected LD_LIBRARY_PATH was removed in favour
of the more general flatpak_bwrap_envp_to_args(). That reasoning only
works if we use flatpak_bwrap_envp_to_args(), consistently, everywhere
that we run the potentially-setuid bwrap.
Fixes: 6d1773d2 "run: Convert all environment variables into bwrap arguments"
