794f75ca61 lib/sysroot: Call chmod on overlay dirs when unlocking
Otherwise, we'll be subject to whatever `umask` is currently. Normally,
processes should respect `umask` when creating files and directories,
but specifically for `ostree admin unlock` (or `rpm-ostree usroverlay`),
this poses a problem since e.g. a `/usr` with mode 0700 will break any
daemon that doesn't run as root and needs to read files under `/usr`,
such as polkitd.

This patch just does a `chmod()` after the `mkdir()`. An alternative
would be to do `umask(0000)` after forking into the child process
that'll call `mount()`, but that'd require also moving the `mkdir()`
calls into there, making for a more intrusive patch.

78747a8a17 lib/repo-refs: Allow resolving local collection-refs
Currently for a "normal" refspec you can choose to use
ostree_repo_resolve_rev_ext() instead of ostree_repo_resolve_rev() if
you only want to look at local refs (in refs/heads/) not remote ones.
This commit provides the analogous functionality for
ostree_repo_resolve_collection_ref() by adding a flag
OSTREE_REPO_RESOLVE_REV_EXT_LOCAL_ONLY and implementing it. This
will be used by Flatpak.

0ecbc6f2a9 lib/repo-refs: Add a flag to exclude listing from refs/mirrors
Currently the flag OSTREE_REPO_LIST_REFS_EXT_EXCLUDE_REMOTES for
ostree_repo_list_collection_refs() means that refs in refs/remotes/
should be excluded but refs in refs/mirrors/ should still be checked, in
addition to refs/heads/ which is always checked. However in some
situations you want to exclude both remote and mirrored refs and only
check local "owned" ones. So this
commit adds a new flag OSTREE_REPO_LIST_REFS_EXT_EXCLUDE_MIRRORS which
lets you exclude refs/mirrors/ from the listing.

This way we can avoid breaking API but still allow the listing of local
collection-refs.

The impetus for this change is that I'm changing Flatpak to make more
use of refs/mirrors, and we need a way to specify that a collection-ref
is local when using ostree_repo_resolve_collection_ref() in, for
example, the implementation of the repo command. The subsequent commit
will make the changes needed there.

23304b8c15 lib/repo-refs: Fix resolving collection-refs
My last commit "lib/repo-refs: Resolve collection-refs in-memory and in
parent repos" changed ostree_repo_resolve_collection_ref() to check the
in-memory set of refs *after* failing to find the ref on disk but that's
not what we want. We want to use the in-memory set of refs first,
because those are the most up to date commits, and then fall back to the
on-disk repo and finally fall back to checking any parent repo. This
commit makes such a change to the order of operations, which is
consistent with how ostree_repo_resolve_rev() works.

Aside from this change being logical, it also fixes some unit test
failures on an unmerged branch of flatpak:

a8754ae370 boot: Activate ostree-finalize-staged even earlier
Really, all `ostree admin finalize-staged` needs is access to `/sysroot`

it gets deactivated later in the shutdown process. This should allow us

c9725d0bef lib/repo-pull: Allow the keyring remote to be overridden
Currently the P2P code requires you to trust every remote you have
configured to the same extent, because a remote controlled by a
malicious actor can serve updates to refs (such as Flatpak apps)
installed from other remotes.[1] The way this attack would play out is
that the malicious remote would deploy the same collection ID as the
victim remote, and would then be able to serve updates for it.

One possible remedy would be to make it an error to configure remotes
such that two have the same collection ID but differing GPG keys. I
attempted to do that in Flatpak[2] but it proved difficult because it is
valid to configure two remotes with the same collection ID, and they may
then each want to update their keyrings which wouldn't happen
atomically.

Another potential solution I've considered is to add a `trusted-remotes`
option to ostree_repo_find_remotes_async() which would dictate which
keyring to use when pulling each ref. However the
ostree_repo_finder_resolve_async() API would still remain vulnerable,
and changing that would require rewriting a large chunk of libostree's
P2P support.

So this commit represents a third attempt at mitigating this security
hole, namely to have the client specify which remote to use for GPG
verification at pull time. This way the pull will fail if the commits
are signed with anything other than the keys we actually trust to serve
updates.

This is implemented as an option "ref-keyring-map" for
ostree_repo_pull_from_remotes_async() and
ostree_repo_pull_with_options() which dictates the remote to be used for
GPG verification of each collection-ref. I think specifying a keyring
remote for each ref is better than specifying a remote for each
OstreeRepoFinderResult, because there are some edge cases where a result
could serve updates to refs which were installed from more than one
remote.

The PR to make Flatpak use this new option is here[3].

978cffed70 lib/deploy: Don't include version twice in bootmenu title
In Silverblue right now, the boot menu title looks like this:

    Fedora 29.20190301.0 (Workstation Edition) 29.20190301.0 (ostree)

This is because RPM-OSTree's `mutate-os-release` feature is enabled,
which injects the OSTree version string directly into `VERSION` and
`PRETTY_NAME`. So appending the version string again is a bit redundant.
Let's just do a simple substring check here before adding the version to
the title.

21ebc7d21e Add sysroot.bootloader repo config key
The sysroot.bootloader key configures the bootloader
that OSTree uses when deploying a sysroot. Having this key
allows specifying behavior not to use the default bootloader
backend code, which is preferable when creating a first
deployment from the sysroot (#1774).

As of now, the key can take the values "auto" or "none". If
the key is not given, the value defaults to "auto".

"auto" causes _ostree_sysroot_query_bootloader() to be used
when writing a new deployment, which is the original behavior
that dynamically detects which bootloader to use.

"none" avoids querying the bootloader dynamically. The BLS
config fragments are still written to
sysroot/boot/loader/entries for use by higher-level software.

More values can be supported in future to specify a single
bootloader, different behavior for the bootloader code, or
a list of bootloaders to try.

77f91d6c6b lib/repo-refs: Resolve collection-refs in-memory and in parent repos
Currently the behavior of ostree_repo_resolve_rev() is that it tries to
resolve a ref to a commit by checking the refs/ directories, but also by
checking for in-memory ref-checksum pairs which are part of an
in-progress transaction and also by checking the parent repo if one
exists. Currently ostree_repo_resolve_collection_ref() only checks the
refs/ directories, so this commit makes its behavior analagous since it
is the analagous API which supports collection-refs.

The impetus for this was that currently Flatpak uses
ostree_repo_resolve_rev() to load a commit after doing a P2P pull in
flatpak_dir_do_resolve_p2p_refs(), but that assumes the ref came from
the same remote that originally provided it, which might not be the case
if more than one remote has the same collection ID configured. And
changing Flatpak to use ostree_repo_resolve_collection_ref() doesn't
work without this patch.

963395217a lib/repo-commit: Relax min-free-space check in prepare_transaction()
We want a case where we can disable the min-free-space check. Initially,
it felt like to add a OSTREE_REPO_PULL_FLAGS_DISABLE_FREE_SPACE_CHECK but
the problem is prepare_transaction() does not have a OstreeRepoPullFlags
parameter which we can parse right here. On top of it, prepare_transaction()
enforces min-free-space check and won't let the transaction proceed if
the check failed.

This is pretty bad in conjunction with "inherit-transaction" as what
Flatpak uses. There is no way to disable this check unless we remove
it altogether from prepare_transaction.

This issue came out to light when flatpak wasn't able to write metadata
after fetching from remote:

[uajain@localhost ~]$ flatpak remote-info flathub org.kde.Platform//5.9
error: min-free-space-size 500MB would be exceeded

Metadata objects helps in housekeeping and restricting them means
restricting crucial UX (like search, new updates) functionalities
in clients like gnome-software. The error banners originated from
these issues are also abrupt and not much helpful to the user. This
is the specific instance of the issue this patches tries to address.

given that we already have a path we drop iif we have a staged
deployment.

To give some time for the preset to make it to systems, we don't yet
drop the explicit call to `systemctl start`. Though we do make it
conditional based on a DEBUG env var so that we can actually test it in
CI for now. Once we're sure this has propagated, we can drop the
`systemctl start` path and the env var together.
