packaging: rpm scriptlet cleanup, handle -p /sbin/ldconfig
The RPM documention indicates that during an rpm install or erase, the
script(lets): %post, %preun, and %postun (and %pre, %build, %install,
etc.) are copied to a temp file, and then the temp file is run as a
(/bin/sh or bash) script.
Unfortunately the documentation is not clear about how rpmbuild and/or
rpm determine where the end of any scriptlet is when it is copied to
the file.
Most things in the key-manager.spec work correctly as is. These are the
%preun, %post, and %postun scriptlets that are "closed" by a following
%preun, %post, and %postun, or potentially another scriptlet, e.g.
%file.
The ones that don't work correctly (only one actually) are those where
there is a comment in the spec file before it is closed by another
scriptlet. Further complicating things is that the type of scriptlet
affects what rpm does and what `rpm -qp --scripts ...` shows.
The specific one that didn't work was the
"postun -n libkey-manager-client -p /sbin/ldconfig" scriptlet.
It is followed by a comment before being "closed" by the %files section (or
scriptlet). It can be written two ways:
"%postun -n libkey-manager-client\n/sbin/ldconfig"
or "%postun -n libkey-manager-client -p /sbin/ldconfig".
Either way it's written, `rpm -qp --scripts libkey-manager-client...`
will include the comment lines between the %postun line and the following %files line.
But the way rpm executes these depends on how they're written. If
written as "%postun -n libkey-manager-client\n/sbin/ldconfig" rpm will simply run
/sbin/ldconfig with no command line options, i.e.

Refactor base64 implementation
This codebase contains two slightly different base64 encoding wrappers,
both using low-level OpenSSL BIO API. The wrappers provide access to a
streaming interface, despite the fact that this property is not used
anywhere. To handle errors, the wrappers sometimes use exceptions and
sometimes return codes. To implement this, a stateful class was used,
and these four facts resulted in needlessly verbose code.
I have merged the two implementations and simplified them to two free
functions. The encode function now uses higher-level OpenSSL EVP API,
and the decode function was refactored.

Optimize, fix memory zeroing and refactor BinaryQueue
BinaryQueue is a class responsible for buffering data received from
sockets before deserialization, vendored from DPL. It stores the
received data as a list of blocks, which is probably the optimal
approach given the constraints of the services framework here. However,
its implementation is a little inefficient and incorrect:
- Stores data in std::vector<unsigned char> instead of RawBuffer.
Because of that, any piece of data that passes through a socket may
live in memory much longer than it should.
- Erases elements from the front of a std::vector. This means all the
other elements need to be shifted, which could even result in
quadratic complexity given large enough socket reads and small enough
messages.
- Always copies incoming data. This means all of incoming traffic has to
be copied one more time than it needs to.
I have fixed the first issue in the obvious way. To fix the second
issue, I have added a new member that tracks how many bytes have been
read from the first bucket in the queue, which makes physically erasing
elements from the vector unnecessary. Lastly, I changed the push
signature from taking a pointer and a size to taking a RawBuffer&&,
which eliminated some copies and made the remaining ones more explicit.

Optimize message serialization
There is a MessageBuffer class, which stores a list of byte slices as
std::list<std::vector<unsigned char>> and can be used for serializing
structs. Every member calls a Write method, which creates a new vector
and appends it to the list. After the list is built, a vector with an
exactly right size is allocated and the data is copied. Also, the class
contains unnecessary mutable state, because the logic is shared with
streaming deserialization.
I have replaced the serialization methods with a single function, which
serializes all objects twice. The first pass ignores the data and only
computes the message size, which allows the second pass that actually
writes the data to only use a single allocation. The new interface is
also simpler and more robust.

Add automatic data decryption to ckm_db_tool
The key manager stores key data in an encrypted database. The project
also contains a ckm_db_tool CLI utility, which decrypts the database and
launches an interactive SQL shell. However, inside the decrypted
database, the data column is still encrypted with application-specific
keys. This is inconvenient during debugging, as there is no easy way to
see the data. Also, decrypting some objects' data may require
object-specific passwords.
This patch adds a --decrypt flag, which automatically decrypts contents
of any column called "data" in all SQL query results. Additionally, if
decryption of an object requires a password, it prompts the user to
enter the password and uses it to decrypt the object's data.
The implementation finds "data", "dataType" and "idx" columns in the
output, assumes they come from the "objects" table, and uses the three
values to fetch and decrypt object data with existing CKM APIs. All rows
are prefixed with a message detailing whether the decryption was
successful.
