We're going to change virStrncpy() in a way that
requires the source string to be NULL-terminated, so
we'll no longer be able to use in this context.
Signed-off-by: Andrea Bolognani <abologna@redhat.com>
Currently, the functions return a pointer to the
destination buffer on success or NULL on failure.
Not only does this kind of error handling look quite
alien in the context of libvirt, where most functions
return zero on success and a negative int on failure,
but it's also somewhat pointless because unless there's
been a failure the returned pointer will be the same
one passed in by the user, thus offering no additional
value.
Change the functions so that they return an int
instead.
Signed-off-by: Andrea Bolognani <abologna@redhat.com>
The strncpy() function has this quirk where it will copy
*up* to the requested number of bytes, that is, it will
stop early if it encounters a NULL byte in the source
string.
This makes it legal to pass the size of the destination
buffer (minus one byte needed for the string terminator)
as the number of bytes to copy and still get something
somewhat reasonable out of the operation; unfortunately,
it also makes the function difficult to reason about
and way too easy to misuse.
We want to move away from the way strncpy() behaves and
towards better defined semantics, where virStrncpy()
will always copy *exactly* the number of bytes it's
been asked to copy; before we can do that, though, we
have to change a few of the callers.

virStrncpy() allows us to copy a substring, but if we're
going to copy the entire thing it's much more convenient
to use virStrcpy() instead.

virStrcpy() and friends are useful when the destination
buffer has already been allocated, eg. as part of a struct;
if we have to allocate it on the spot, VIR_STRDUP() is a
better choice.

This convenience macro was created for the simple cases
where the length of the source string and the size of the
destination buffer can be figued out with strlen() and
sizeof() respectively, so we should use it wherever
possible instead of open-coding parts of it.
Signed-off-by: Andrea Bolognani <abologna@redhat.com>
The way virStrncpy() is called here will never result in
buffer overflow, but it won't prevent or detect truncation
either, despite what the error message might suggest. Use
virStrcpyStatic(), which does all of the above, instead.

When gnutls negotiates TLS 1.3 instead of 1.2, the order of messages
sent by the handshake changes. This exposed a logic bug in the test
suite which caused us to wait for the server to see handshake
completion, but not wait for the client to see completion. The result
was the client didn't receive the certificate for verification and the
test failed.
This is exposed in Fedora 29 rawhide which has just enabled TLS 1.3 in
its GNUTLS builds.
