Marc-André Lureau	653163fcbc	build-sys: add HAVE_IPPROTO_MPTCP The QAPI schema shouldn't rely on C system headers #define, but on configure-time project #define, so we can express the build condition in a C-independent way.

Markus Armbruster	935a867c87	qapi: Convert simple union SocketAddressLegacy to flat one Simple unions predate flat unions. Having both complicates the QAPI schema language and the QAPI generator. We haven't been using simple unions in new code for a long time, because they are less flexible and somewhat awkward on the wire. To prepare for their removal, convert simple union SocketAddressLegacy to an equivalent flat one, with existing enum SocketAddressType replacing implicit enum type SocketAddressLegacyKind. Adds some boilerplate to the schema, which is a bit ugly, but a lot easier to maintain than the simple union feature. Cc: "Daniel P.

Marc-André Lureau	8a9f1e1d9c	qapi: make 'if' condition strings simple identifiers Change the 'if' condition strings to be C-agnostic. It will accept '[A-Z][A-Z0-9_]*' identifiers. This allows to express configuration conditions in other languages (Rust or Python for ex) or other more suitable forms.

Dr. David Alan Gilbert	8bd1078aeb	sockets: Support multipath TCP Multipath TCP allows combining multiple interfaces/routes into a single socket, with very little work for the user/admin.

Markus Armbruster	8acefc79de	sockets: Make abstract UnixSocketAddress depend on CONFIG_LINUX The abstract socket namespace is a non-portable Linux extension. An attempt to use it elsewhere should fail with ENOENT (the abstract address looks like a "" pathname, which does not resolve). We report this failure like Failed to connect socket abc: No such file or directory Tolerable, although ENOTSUP would be better. However, introspection lies: it has @abstract regardless of host support. Easy enough to fix: since Linux provides them since 2.2, 'if': 'defined(CONFIG_LINUX)' should do. The above failure becomes Parameter 'backend.data.addr.data.abstract' is unexpected I consider this an improvement.

Andrea Bolognani	f7160f3218	schemas: Add vim modeline The various schemas included in QEMU use a JSON-based format which is, however, strictly speaking not valid JSON. As a consequence, when vim tries to apply syntax highlight rules for JSON (as guessed from the file name), the result is an unreadable mess which mostly consist of red markers pointing out supposed errors in, well, pretty much everything. Using Python syntax highlighting produces much better results, and in fact these files already start with specially-formatted comments that instruct Emacs to process them as if they were Python files. This commit adds the equivalent special comments for vim. Signed-off-by: Andrea Bolognani <abologna@redhat.com> Message-Id: <20200729185024.121766-1-abologna@redhat.com> Reviewed-by: Daniel P.

Peter Maydell	26ec4e53f2	qapi: Fix indent level on doc comments in json files The current doc generation doesn't care much about indentation levels, but we would like to switch to an rST format, and rST does care about indentation. Make the doc comments more strongly consistent about indentation for multiline constructs like: @arg: description line 1 description line 2 Returns: line one line 2 so that there is always exactly one space after the colon, and subsequent lines align with the first. This commit is a purely whitespace change, and it does not alter the generated .texi files (because the texi generation code strips away all the extra whitespace). This does mean that we end up with some over-length lines. Note that when the documentation for an argument fits on a single line like this: @arg: one line only then stray extra spaces after the ':' don't affect the rST output, so I have not attempted to methodically fix them, though the preference is a single space here too.

Daniel P. Berrange	1723d6b1cf	sockets: allow SocketAddress 'fd' to reference numeric file descriptors The SocketAddress 'fd' kind accepts the name of a file descriptor passed to the monitor with the 'getfd' command. This makes it impossible to use the 'fd' kind in cases where a monitor is not available. This can apply in handling command line argv at startup, or simply if internal code wants to use SocketAddress and pass a numeric FD it has acquired from elsewhere. Fortunately the 'getfd' command mandated that the FD names must not start with a leading digit. We can thus safely extend semantics of the SocketAddress 'fd' kind, to allow a purely numeric name to reference an file descriptor that QEMU already has open. There will be restrictions on when each kind can be used. In codepaths where we are handling a monitor command (ie cur_mon != NULL), we will only support use of named file descriptors as before. Use of FD numbers is still not permitted for monitor commands. In codepaths where we are not handling a monitor command (ie cur_mon == NULL), we will not support named file descriptors. Instead we can reference FD numers explicitly. This allows the app spawning QEMU to intentionally "leak" a pre-opened socket to QEMU and reference that in a SocketAddress definition, or for code inside QEMU to pass pre-opened FDs around.
