Colin Walters 1b8fed247c lib: Move gpg/signapi bits into ostree-repo-pull-verify.c
`ostree-repo-pull.c` is huge; separate some of the GPG/signing
verification functions into their own file so they're more easily seen.

Jonathan Lebon 8ece36c28a lib/commit: Check that dirent is a directory before cleaning
I've only noticed this by inspection. But I think it's possible for
`cleanup_txn_dir` to get called with the `staging-...-lock` file since
it matches the prefix.

Make the checking here stronger by verifying that it's a directory. If
it's not a directory (lockfile), then follow the default pruning expiry
logic so that we still cleanup stray lockfiles eventually.

Jonathan Lebon df065ad766 lib: Rename function for staging dir check

Colin Walters b7f48a74c0 lib: Move internal binding verification API to repo.c
`ostree-repo-pull.c` is rather monstrous; I plan to split it
up a bit.  There's actually already a `pull-private.h` but
that's just for the binding verification API.  I think that one
isn't really pull specific.  Let's move it into the "catchall"
`repo.c`.

Colin Walters 8e7aea4473 Change signature opts to include type, cleanup error handling
Previously we would pass the `verification-key` and `verification-file`
to all backends, ignoring errors from loading keys until we
found one that worked.

Instead, change the options to be `verification-<engine>-key`
and `verification-<engine>-file`, and then
rework this to use standard error handling; barf explicitly if
we can't load the public keys for example.  Preserve
the semantics of accepting the first valid signature.  The
first signature error is captured, the others are currently
compressed into a `(and %d more)` prefix.

And now that I look at this more closely there's a lot of
duplication between the two code paths in pull.c for verifying;
will dedup this next.

Colin Walters e035230c6b lib/pull: Two cosmetic internal function renames
I'm mainly doing this to sanity check the CI state right now.

However, I also want to more cleanly/clearly distinguish
the "sign" code from the "gpg" code.

Rename one function to include `gpg`.

For the other...I think what it's really doing is using the remote
config, so change it to include `remote` in its name.

Denis Pynkin ef1aeb7458 lib/repo-pull: fix GPG check while pulling remote
If GPG support is disabled in a build time we should to check if any of
options "gpg_verify" or "gpg_verify_summary" is set to TRUE instead
of checking if they are passed via options while pulling from remote.

Fixed the failure with assertion of `ostree find-remotes --pull --mirror`
calling (`tests/test-pull-collections.sh`) if libostree has been compiled
without GPG support.

Colin Walters 329a82c57e commit: Add --base argument
I was trying to followup the `--selinux-policy-from-base` work
to add a `cosa build --fast=overlay` for coreos-assembler,
but hit on the fact that using e.g. `--owner-uid` disables
commit optimizations.

A while ago, https://github.com/ostreedev/ostree/pull/1643 landed
which optimized this for the case where no modifications are provided.
But, we really need the SELinux policy bits, and it's super convenient
to run `ostree commit` as non-root.

It's fairly surprising actually that it's taken us so long to
iterate on a good interface for this "commit changes on top of a base"
model.  In practice, many nontrivial cases really end up needing
to do a (hardlink) checkout, and that case is optimized.

But for this coreos-assembler work I want to directly overlay onto
a commit object another commit object.

That previous PR above added exactly the API we need, so let's
expose it in the CLI.

What you can see happening in the test is that we provide
`--owner-uid 42`, but that only applies to directories/files
that were added in the commit.

And now that I look at this, I think what we really want here
is to avoid changing directories that exist in the base, but
eh; in practice the main use here is for `--owner-uid 0` while
committing as non-root; and that works fine with this since
the baseline uid will be zero as well.

grub2: Don't add menu entries if GRUB supports parsing BLS snippets
This is another attempt to avoid having duplicated menu entries caused by
GRUB having support to parse BLS snippets and the 15_ostree script adding
menu entries as well.

The previous attempt was in commit 985a141002 ("grub2: Exit gracefully if
the configuration has BLS enabled") but that lead to users not having menu
entries at all, due having an old GRUB version that was not able to parse
the BLS snippets.

This happened because the GRUB bootloader is never updated in the ESP as
a part of the OSTree upgrade transaction.

The logic is similar to the previous commit, the 15_ostree script exits if
able to determine that the bootloader can parse the BLS snippets directly.

But this time it will not only check that a BLS configuration was enabled,
but also that a /boot/grub2/.grub2-blscfg-supported file exists. This file
has to be created by a component outside of OSTree that also takes care of
updating GRUB to a version that has proper BLS support.

Colin Walters 47539874b8 pull: Update key loading function to match error style
This code wasn't written with idiomatic GError usage; it's not standard
to construct an error up front and continually append to its
message.  The exit from a function is usually `return TRUE`,
with error conditions before that.

Updating it to match style reveals what I think is a bug;
we were silently ignoring failure to parse key files.

2020-03-29 01:04:57 +01:00
Matthew Leeds 164b2aa35b Don't copy summary for collection-ref mirror subset pulls
When we're only pulling a subset of the refs available in the remote, it
doesn't make sense to copy the remote's summary (which may not be valid
for the local repo). This makes the check here match the one done
several lines above when we decide whether to error out if there's no
remote summary available.

This extends the fix in https://github.com/ostreedev/ostree/pull/935 for
the case of collection-refs.

Also, add a unit test for this issue, based on the existing one in
pull-test.sh.

Noticed this while writing tests for a core `ostree_sysroot_load()`
entrypoint.  And decided to do the same for `ostree_repo_open()`,
and while there also noted we had a duplicate error prefixing
for the open (more recently `glnx_opendirat()` automatically
prefixes with the path).
