2020-08-03schemas: Add vim modelineAndrea Bolognani
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.

2020-02-15qapi: Add blank lines before bulleted listsPeter Maydell
We would like to switch the doc comments to rST format. rST insists on a blank line before and after a bulleted list, but our Texinfo doc generator did not. Add some extra blank lines in the doc comments so they're acceptable rST input.

2020-02-15qapi: Fix indent level on doc comments in json filesPeter Maydell
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.

2019-03-11chardev: add support for authorization for TLS clientsDaniel P. Berrange
Currently any client which can complete the TLS handshake is able to use a chardev server. The server admin can turn on the 'verify-peer' option for the x509 creds to require the client to provide a x509 certificate. This means the client will have to acquire a certificate from the CA before they are permitted to use the chardev server. This is still a fairly low bar. This adds a 'tls-authz=OBJECT-ID' option to the socket chardev backend which takes the ID of a previously added 'QAuthZ' object instance. This will be used to validate the client's x509 distinguished name. Clients failing the check will not be permitted to use the chardev server. For example to setup authorization that only allows connection from a client whose x509 certificate distinguished name contains 'CN=fred', you would use: $QEMU -object tls-creds-x509,id=tls0,dir=/home/berrange/qemutls,\ endpoint=server,verify-peer=yes \ -object authz-simple,id=authz0,identity=CN=laptop.example.com,,\ O=Example Org,,L=London,,ST=London,,C=GB \ -chardev socket,host=127.0.0.1,port=9000,server,\ tls-creds=tls0,tls-authz=authz0 \ ...other qemu args...

2018-07-03qapi: add conditions to SPICE type/commands/events on the schemaMarc-André Lureau
Add #if defined(CONFIG_SPICE) in generated code, and adjust the qmp/hmp code accordingly. query-qmp-schema no longer reports the command/events etc as available when disabled at compile time. Commands made conditional: * query-spice Before the patch, the command for !CONFIG_SPICE is unregistered. It will fail with the same error. Events made conditional: * SPICE_CONNECTED, SPICE_INITIALIZED, SPICE_DISCONNECTED, SPICE_MIGRATE_COMPLETED Add TODO for conditional SPICE chardevs, delayed until the supports for conditional members lands. No HMP change, the code was already conditional.

2018-06-21qmp: Enable a few commands in preconfig stateIgor Mammedov
Commands query-chardev, query-version, query-name, query-uuid, query-iothreads, query-memdev are informational and do not depend on the machine being initialized. Make them available in preconfig runstate to make the latter a little bit more useful. The generic qom commands don't depend on the machine being initialized either; so enabled qom-list, qom-get, qom-set, qom-list-types, qom-list-properties.
