Matthew Leeds 6ea21696a3 Fix building against old glib versions
We need to include libglnx.h in places where ostree-autocleanups.h is
included, so that we get backports of G_DEFINE_AUTOPTR_CLEANUP_FUNC and
friends.

Matthew Leeds 1d830c1792 Revert "lib: Fix building against old glib versions"
This reverts commit f1d9196076.

Since libglnx.h does not get installed, it can't be included in
ostree-autocleanups.h, which is included by ostree.h.

Matthew Leeds 8fbf19c9f5 Make P2P API public (no longer experimental)
Currently the API that allows P2P operations (e.g. pulling an ostree ref
from a LAN or USB source) is hidden behind the configure flag
--enable-experimental-api. This commit makes the API public and makes
that flag essentially a no-op (leaving it in place in case we want to
use it again in the future). The P2P API has been tested over the last
several months and proven to work.

This means that since we're no longer using the "experimental" feature
flag, P2P builds of Flatpak will fail when using versions of OSTree from
this commit onwards, until Flatpak is patched in the near future. If you
want to build Flatpak < 0.11.8 with P2P enabled and link against OSTree
2018.6, you'll have to patch Flatpak.  However, since Flatpak won't yet
have a hard dependency on OSTree 2018.6, it needs a new way to determine
if the P2P API in OSTree is available, so this commit adds a "p2p"
feature flag. This way the feature set is more semantically correct than
if we had continued to use the "experimental" feature flag.

In addition to making the P2P API public, this commit makes the P2P unit
tests run by default, removes the f27-experimental CI instance that's no
longer needed, changes a few man pages to reflect the changes, and
updates the bash completion script to accept the new commands and
options.

Philip Withnall f342e66c11 lib/repo-pull: Support queuing delta superblock requests
Just like all the other requests made for delta parts and objects by the
pull code, use a queue for delta superblocks. Currently this doesn’t do
any prioritisation or retries after transient failures, but it could do
in future.

This means that delta superblocks are now subject to the parallel
request limit in the fetcher, which was a problem highlighted here:

Philip Withnall 938055392f lib/repo-pull: Support retrying requests on transient network errors
Allow network requests to be re-queued if they failed with a transient
error, such as a socket timeout. Retry each request up to a limit
(default: 5), and only then fail the entire pull and propagate the error
to the caller.

Add a new ostree_repo_pull_with_options() option, n-network-retries, to
control the number of retries (including setting it back to the old
default of 0, if the caller wants).

Currently, retries are not supported for FetchDeltaSuperData requests,
as they are not queued. Once they are queued, adding support for retries
should be trivial. A FIXME comment has been left for this.

Matthew Leeds 2b32de38cf Allow compiling with experimental API but without curl/soup
This commit rearranges a few things in ostree-repo-pull.c so that OSTree
will successfully compile with experimental API enabled and without
libsoup, libcurl, or avahi:

./autogen.sh --enable-experimental-api --without-soup --without-curl
--without-avahi

This is accomplished with two sets of changes:

1. Move ostree_repo_resolve_keyring_for_collection() so it can be used
even without libsoup or libcurl.
2. Add stub functions for ostree_repo_find_remotes_async() and
ostree_repo_pull_from_remotes_async(), and their _finish() counterparts,
so they return an error when libsoup or libcurl isn't available.

Colin Walters 9131d8a4cc lib/sysroot: Add wrapper API to prune system repository
The initial motivation for this is that the "staging" code currently
didn't rewrite the deployment refs, meaning that the staged commit
could be pruned.

Hence first, this new API ensures that deployments also
hold a strong ref to their commit, without relying on the magical
"deployment refs" that we inject.  That has always been a weird
artifact of the strict layering separation between OstreeSysroot
and OstreeRepo.

I also plan to change rpm-ostree to start using this API to
hold references to base layers for client-side layering; it also
today generates various refs.

That said, if we still want to support multiple processes
writing to a single repo (as happens on EndlessOS today) we
still need to write refs; perhaps later we could add a concept
of "generators" or something that create refs based on whatever
logic?

Another minor thing this fixes is that we had a printf inside
the library; this propagates the pruned data to the higher level
which can log however it likes.

Andrea Galbusera ce2995e1dc u-boot: add support for devicetree
Likewise the corresponding support for syslinux introduced by commit
c5112c25e4, this one enables writing devicetree
filename into the uEnv.txt environment file for u-boot.

Since u-boot does not strictly defines variable names, here 'fdt_file' was
chosen as it appear to be one the most frequently adopted names in u-boot
default environments. Outer boot logic should of course comply with this choice
and use $fdt_file as the device tree file name to pass to boot commands.

This was tested on a custom board booting with u-boot.

Anyways, since we made the feature opt-in in rpm-ostree in

Tobias Mueller 5ee78ea42a repo: handle GPG_ERR_AMBIGUOUS_NAME in sign_data
This should give a more insightful error message if the user provides
a UID which is present on multiple keys.
This happens if you have an old key in your keyring which you are not
actively using any more, e.g. because it is too old.  You still have
your old keys in your keyring, because you want to read old email
encrypted for that key, though.

The gpgme function used by ostree right now complains if a UID is found
on multiple keys:
https://www.gnupg.org/documentation/manuals/gpgme/Listing-Keys.html#index-gpgme_005fget_005fkey
The used API is too simple for that use case.

Note that it would be nicer if ostree picked the only valid signing key out
of the available keys rather than using the simplistic gpgme_get_key
function.  It be nicer, of course, if there was such a gpgme function.

Colin Walters d0a1832347 deploy: Use fdatasync() for new kernel/initramfs by default
While we do a `syncfs()` plus `FIFREEZE/THAW` for `/boot`, that
only comes during deployment finalization.

The code here today generally assumes that if the file exists
it's been fully written.  So let's do a `fdatasync()` before
we do the `rename()`.

This just came out of looking through the code while working
on deployment staging.  In that scenario there's a much larger
window between when we copy the kernel/initramfs and when we
sync `/boot`.

Colin Walters 8c1542134c lib/repo: Enable locking by default, but drop external API
The code has been sitting around for a while but since I disabled
it by default, I doubt anyone is really using it or relying on it.

This patch and turns on locking by default, and also drops the
API which was only public in the experimental API builds.
Conceptually these are two distinct things, and we
may actually want to split up the patches.

I don't think this will break anyone, but it's hard to say for sure.
It's also going to be hard to find out until we actually release
I suspect...

But anyone who is broken should be able to add `locking=false` into
their repo config.  On the flip side Endless has been shipping with
this enabled and it is reported to help.

The reason to drop the APIs: I'm a bit concerned about the interactions over time
between libostree's use of the API and any apps that start using it.
For example, if an app specifies a SHARED lock in their code, then
later internally we decide to temporarily grab an `EXCLUSIVE`, but the
app had a second thread/process that was `EXCLUSIVE` already, and
that process was waiting on the first bit of code, then we could
deadlock. I can't think of a real world situation where this would happen
yet though.

We are likely to in the future have say `fsck` take an external lock,
`checkout` grab a shared one, etc.

Colin Walters de4c7105f0 lib/deploy: Fix staged deployments with no kargs
Testing out the staged API with rpm-ostree, ostree-prepare-root.service
in the initramfs was failing.  Turned out that was because we didn't
have a `root=` kernel argument.  Which was because we didn't have
any kernel arguments at all except `ostree=`.

That in turn was because we weren't loading the bootloader config
from the merge deployment.

The serialized deployment data holds the unique identity of
(osname, checksum, deployserial) - look for the real merge deployment
in our deployment list which has the bootloader arguments we need.

This issue was entirely masked by the `ostree admin deploy` command
which itself explicitly loads the merge deployment's kernel arguments
in every case - it never passes the `NULL` default down.  A followup
patch will fix that.
