Denis Pynkin 0108e9ea49 gpg: conditionally build GPG-related code for sign/verification
Do not build the code related to GPG sign and verification if
GPGME support is disabled.
Public functions return error 'G_IO_ERROR_NOT_SUPPORTED' in case if
gpg-related check is rquested.

Dan Nicholson 4670837f7c lib/gpg: Add helper to kill GPG agent
With GnuPG 2, any time you do basically any operation, a gpg-agent will
be spawned for the GPG home directory in use. The classic way to kill a
gpg-agent is to use `gpg-connect-agent` and send the `killagent` command
as is done in libtest.sh.

rfairley 05e8c7ef6a lib/repo: Search a list of paths in gpgkeypath for gpg keys
This allows specifying gpgpath as list of
paths that can point to a file or a directory. If a directory path
is given, paths to all regular files in the directory are added
to the remote as gpg ascii keys. If the path is not a directory,
the file is directly added (whether regular file, empty - errors
will be reported later when verifying gpg keys e.g. when pulling).

Adding the gpgkeypath property looks like:

ostree --repo=repo remote add --set=gpgpath="/path/key1.asc,/path/keys.d" R1 https://example.com/some/remote/ostree/repo

Jonathan Lebon 968e8805b0 lib: Fix some logic/error-checking code
Using `MAX(0, $x)` here is useless since we're comparing against an
unsigned integer. Just unpack this and only subtract if it's safe to do
so.

Also, explicitly check for `fd >= 0` rather than just `!= -1` to be sure
it's a valid fd. And finally, explicitly check the return value of
`g_input_stream_read_all` as is done everywhere else in the tree and
make it clear that we're purposely ignoring the return value of `_flush`
here, but not in other places.

Matthew Leeds 9721be34e1 libotutil/checksum-utils: Fix memory management
Ostree uses the OtChecksum data structure as a wrapper around GChecksum
(depending on what libraries are available at compile time). According
to the docs for g_checksum_get_digest(), a GChecksum value can no longer
be updated after that function is called. Ostree enforces this by
setting "initialized" to FALSE after getting the digest, but this leads
to ot_checksum_clear() avoiding freeing any memory, leading to leaks. So
this commit adds a "closed" value that gets set when getting a digest
and checked when updating the value, so the initialized value can be
used only for memory management.

Marcus Folkesson 6bf4b3e1d8 Add SPDX-License-Identifier to source files
SPDX License List is a list of (common) open source
licenses that can be referred to by a “short identifier”.
It has several advantages compared to the common "license header texts"
usually found in source files.

Some of the advantages:
* It is precise; there is no ambiguity due to variations in license header
  text
* It is language neutral
* It is easy to machine process
* It is concise
* It is simple and can be used without much cost in interpreted
  environments like java Script, etc.
* An SPDX license identifier is immutable.
* It provides simple guidance for developers who want to make sure the
  license for their code is respected

Colin Walters f81e3c6f03 lib/commit: Use more direct path for regfile commits
In the non-`CONSUME` path for regfiles (which happens currently for
`bare-user`), we go to a lot of contortions to make an "object stream",
only to immediately parse it again.

Fixing this will also enable the `G_IS_FILE_DESCRIPTOR_BASED()` fast path in
commit, since the input stream will actually reference the file descriptor and
not be an `_OstreeChainInputStream`.

There's a slight concern here in that we're no longer checksumming *literally*
the object stream passed in for the stream case, but I mention in the comment,
the data should be the same, and if it's not somehow we're not adding risk,
since the checksum is still covering the data we actually care about.

Prep for further changes to break up the `write_content_object()` path into
separate paths for archive, as well as regfile vs symlink in non-archive.

Colin Walters bb51a43d81 lib/core: Use GBytes for file headers
This simplifies a lot of code; the header function was structured
to write to an input stream, but many callers only wanted the checksum,
so it's simpler (and error-free) to simply allocate a whole buffer
and checksum that.

For the callers that want to write it, it's also still simpler to allocate the
buffer and write the whole thing rather than having this function do the
writing.

A lot of the complexity here again is a legacy of the packfile code, which is
dead.

This is prep for faster regfile commits where we can avoid `G{In,Out}putStream`.

Colin Walters 1c9975cbd1 lib: Add a lighter weight internal checksum wrapper
The faster (OpenSSL/GnuTLS) code lived in a `GInputStream` wrapper, and that
adds a lot of weight (GObject + vtable calls). Move it into a simple
autoptr-struct wrapper, and use it in the metadata path, so we're
now using the faster checksums there too.

This also drops a malloc there as the new API does hexdigest in place to a
buffer.

Colin Walters 5c7d2dd8be Deduplicate and fix up our use of mmap()
Buried in this large patch is a logical fix:

```
-  if (!map)
-    return glnx_throw_errno_prefix (error, "mmap");
+  if (map == (void*)-1)
+    return glnx_null_throw_errno_prefix (error, "mmap");
```

Which would have helped me debug another patch I was working
on.  But it turns out that actually correctly checking for
errors from `mmap()` triggers lots of other bugs - basically
because we sometimes handle zero-length variants (in detached
metadata).  When we start actually returning errors due to
this, things break.  (It wasn't a problem in practice before
because most things looked at the zero size, not the data).

Anyways there's a bigger picture issue here - a while ago
we made a fix to only use `mmap()` for reading metadata from disk
only if it was large enough (i.e. `>16k`).  But that didn't
help various other paths in the pull code and others that were
directly doing the `mmap()`.

Fix this by having a proper low level fs helper that does "read all data from
fd+offset into GBytes", which handles the size check. Then the `GVariant` bits
are just a clean layer on top of this. (At the small cost of an additional
allocation)

Side note: I had to remind myself, but the reason we can't just use
`GMappedFile` here is it doesn't support passing an offset into `mmap()`.

Jussi Laako f91acf5226 Add --with-crypto=gnutls
Introduce support for GnuTLS for computing cryptograpic
hashes, similar to the OpenSSL backend.  A reason to do
this is some distributors want to avoid GPLv3, and GPG
pulls that in.

A possible extension of using GnuTLS would be replacing the GPG signing
with `PKCS#7` signatures and `X.509` keys.

We also support `--with-crypto=openssl`, which has the same effect
as `--with-openssl`, and continues to be supported.

 - Drop libgcrypt option for now
 - Unify buildsystem on --with-crypto

Colin Walters 5776d5dcc0 Port to GLnxTmpfile
There's lots of mechanically replacing `OtTmpFile` with `GLnxTmpfile`;
the biggest changes are in the commit path.  Symlink commits are now
very clearly separated from regular files.  Symlinks are `OtCleanupUnlinkat`,
and regular files are `GLnxTmpfile`.

The commit codepath separates those as `_ostree_repo_commit_path_final()` and
`_ostree_repo_commit_tmpf_final()`. A nice aspect of all of this is that they
both *consume* the temporary on success. This avoids an extra spurious
`unlink()` call.

One of the biggest bits of code motion is in `commit_loose_regfile_object()`,
which no longer needs to care about symlinks. For the most parth though it's
just removing conditionals.

there's no reason to have different lifetimes for the filename and the file, and
that way we only have one variable rather than two.

The content path turns out to be a special case though, where
at least for mirroring archives, we directly pass the file *path*
down into `_ostree_repo_commit_loose_final()`.

Colin Walters 49a525f6a5 repo: Optimize bare-user content object reads a bit
`perf record ostree checkout ...` for a bare-user repo was telling
me we were spending a good 13% of our time in the depchain of `ot_lgexattrat()`.
The problem here is that traversing the `/proc` path turns out to be
somewhat expensive - there are LSM (SELinux) checks, etc.

For regular files, opening and just getting the xattr, then closing is still
quite cheap. For symlinks, we'll always need to open anyways.

This appears to shave about ~0.1 seconds off of a checkout of
`fedora-atomic/25/x86_64/docker-host` on my workstation.

Oh, and this was the last user of `ot_lgexattrat()` so we can kill it, which is
nice - the xattr code should really live in libglnx.
