Jonathan Lebon 9332830e09 lib/pull: Allow downgrade protection with overrides
There's a valid use case for enabling the timestamp downgrade check
while still also using override commits.

We'll make use of this in Fedora CoreOS, where the agent specifies the
exact commit to upgrade to, while still enforcing that it be newer.

Dan Nicholson 19e764cea2 lib/kargs: Don't expose OstreeKernelArgs autoptr cleanup on old glib
Move the OstreeKernelArgs autoptr cleanup definition to
ostree-autocleanups.h, which will only expose the definitions when
building ostree or if glib is new enough. The include of
ostree-kernel-args.h needs to be moved before ostree-autocleanups.h in
ostree.h so that the OstreeKernelArgs type is declared when the autoptr
cleanup is defined. All the places it's used already pull in libglnx.h
first so that the compat macros are picked up if glib it too old during
the ostree build.

Dan Nicholson b6979e7572 lib: Kill GPG agent when cleaning up tmp homedirs
When a temporary directory is used for GPG operations, it's pretty clear
that the running agent will be useless after the directory is deleted.
Call the new `ot_gpgme_kill_agent ()` helper to kill gpg-agent rather
than leaving them it hanging around forever.

As it turns out, gnupg does have code to make gpg-agent automatically
exit when the homedir is removed (https://dev.gnupg.org/T2756), but
that's only available on gnupg 2.2 or newer. Possibly this code can be
dropped later when that's more widely deployed or users/distros have
been advised to backport the necessary changes.

Dan Nicholson d916383953 bin/refs: Allow overwriting existing ref
Currently if you want to update a non-alias ref, you need to first check
if it exists and use either `ostree refs --create` or `ostree reset` as
appropriate. That's unnecessarily complicated and is much less
convenient than the old `write-refs` builtin that simply called
`ostree_repo_set_ref_immediate()` without any checks.

Add a `--force` option to be used with `--create` that does not raise an
error when the destination ref already exists.

Jonathan Lebon 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.

Matthew Leeds 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.

Matthew Leeds 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.

Matthew Leeds 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:
https://github.com/flatpak/flatpak/pull/2705

Also, tweak the comments here.

Matthew Leeds 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].

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

Robert Fairley 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.
