* migration: Move qjson.[ch] to migration/Markus Armbruster2016-05-231-1/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | Type QJSON lets you build JSON text. Its interface mirrors (a subset of) abstract JSON syntax. QAPI output visitors also produce JSON text. They assert their preconditions and invariants, and therefore abort on incorrect use. Contrastingly, QJSON does *not* detect incorrect use. It happily produces invalid JSON then. This is what migration wants. QJSON was designed for migration, and migration is its only user. Move it to migration/ for proper coverage by MAINTAINERS, and to deter accidental use outside migration.

* crypto: add cryptographic random byte sourceDaniel P. Berrange2016-03-171-1/+1
| | | | | | | | | | | | | | There are three backend impls provided. The preferred is gnutls, which is backed by nettle in modern distros. The gcrypt impl is provided for cases where QEMU build against gnutls is disabled, but crypto is still desired. No nettle impl is provided, since it is non-trivial to use the nettle APIs for random numbers. Users of nettle should ensure gnutls is enabled for QEMU.

* io: add abstract QIOChannel classesDaniel P. Berrange2015-12-181-0/+5
| | | | | | | | | | | | | | | | | Start the new generic I/O channel framework by defining a QIOChannel abstract base class. This is designed to feel similar to GLib's GIOChannel, but with the addition of support for using iovecs, qemu error reporting, file descriptor passing, coroutine integration and use of the QOM framework for easier sub-classing. The intention is that anywhere in QEMU that almost anywhere that deals with sockets will use this new I/O infrastructure, so that it becomes trivial to then layer in support for TLS encryption. This will at least include the VNC server, char device backend and migration code. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>

* coroutine: move into libqemuutil.a libraryDaniel P. Berrange2015-10-201-4/+0Star
| | | | | | | | | | | | | | | | | The coroutine files are currently referenced by the block-obj-y variable. The coroutine functionality though is already used by more than just the block code. eg migration code uses coroutine yield. In the future the I/O channel code will also use the coroutine yield functionality. Since the coroutine code is nicely self-contained it can be easily built as part of the libqemuutil.a library, making it widely available. The headers are also moved into include/qemu, instead of the include/block directory, since they are now part of the util codebase, and the impl was never in the block/ directory either.

* qapi: New QMP command query-qmp-schema for QMP introspectionMarkus Armbruster2015-09-211-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | qapi/introspect.json defines the introspection schema. It's designed for QMP introspection, but should do for similar uses, such as QGA. The introspection schema does not reflect all the rules and restrictions that apply to QAPI schemata. A valid QAPI schema has an introspection value conforming to the introspection schema, but the converse is not true. Introspection lowers away a number of schema details, and makes implicit things explicit: * The built-in types are declared with their JSON type. All integer types are mapped to 'int', because how many bits we use internally is an implementation detail. It could be pressed into external interface service as very approximate range information, but that's a bad idea. If we need range information, we better do it properly. * Implicit type definitions are made explicit, and given auto-generated names: - Array types, named by appending "List" to the name of their element type, like in generated C. - The enumeration types implicitly defined by simple union types, named by appending "Kind" to the name of their simple union type, like in generated C. - Types that don't occur in generated C. Their names start with ':' so they don't clash with the user's names. * All type references are by name. * The struct and union types are generalized into an object type. * Base types are flattened. * Commands take a single argument and return a single result. Dictionary argument or list result is an implicit type definition. The empty object type is used when a command takes no arguments or produces no results. The argument is always of object type, but the introspection schema doesn't reflect that. The 'gen': false directive is omitted as implementation detail. The 'success-response' directive is omitted as well for now, even though it's not an implementation detail, because it's not used by QMP. * Events carry a single data value. Implicit type definition and empty object type use, just like for commands. The value is of object type, but the introspection schema doesn't reflect that. * Types not used by commands or events are omitted. Indirect use counts as use. * Optional members have a default, which can only be null right now Instead of a mandatory "optional" flag, we have an optional default. No default means mandatory, default null means optional without default value. Non-null is available for optional with default (possible future extension). * Clients should *not* look up types by name, because type names are not ABI. Look up the command or event you're interested in, then follow the references. TODO Should we hide the type names to eliminate the temptation? New generator scripts/qapi-introspect.py computes an introspection value for its input, and generates a C variable holding it. It can generate awfully long lines. Marked TODO. A new test-qmp-input-visitor test case feeds its result for both tests/qapi-schema/qapi-schema-test.json and qapi-schema.json to a QmpInputVisitor to verify it actually conforms to the schema. New QMP command query-qmp-schema takes its return value from that variable. Its reply is some 85KiBytes for me right now. If this turns out to be too much, we have a couple of options: * We can use shorter names in the JSON. Not the QMP style. * Optionally return the sub-schema for commands and events given as arguments. Right now qmp_query_schema() sends the string literal computed by qmp-introspect.py. To compute sub-schema at run time, we'd have to duplicate parts of qapi-introspect.py in C. Unattractive. * Let clients cache the output of query-qmp-schema. It changes only on QEMU upgrades, i.e. rarely. Provide a command query-qmp-schema-hash. Clients can have a cache indexed by hash, and re-query the schema only when they don't have it cached. Even simpler: put the hash in the QMP greeting. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>

| | | | | | | | | | | | The qom objects are currently added to common-obj-y which is only linked into the system emulators.

* crypto: move crypto objects out of libqemuutil.laDaniel P. Berrange2015-09-151-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | Future patches will be adding more crypto related APIs which rely on QOM infrastructure. This creates a problem, because QOM relies on library constructors to register objects. When you have a file in a static .a library though which is only referenced by a constructor the linker is dumb and will drop that file when linking to the final executable :-( The only workaround for this is to link the .a library to the executable using the -Wl,--whole-archive flag, but this creates its own set of problems because QEMU is relying on lazy linking for libqemuutil.a. Using --whole-archive majorly increases the size of final executables as they now contain a bunch of object code they don't actually use. The least bad option is to thus not include the crypto objects in libqemuutil.la, and instead define a crypto-obj-y variable that is referenced directly by all the executables that need this code (tools + softmmu, but not qemu-ga). We avoid pulling entire of crypto-obj-y into the userspace emulators as that would force them to link to gnutls too, which is not required. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
* crypto: introduce new module for computing hash digestsDaniel P. Berrange2015-07-071-0/+1
| | | | | | | | | | | | | | | | | Introduce a new crypto/ directory that will (eventually) contain all the cryptographic related code. This initially defines a wrapper for initializing gnutls and for computing hashes with gnutls. The former ensures that gnutls is guaranteed to be initialized exactly once in QEMU regardless of CLI args. The block quorum code currently fails to initialize gnutls so it only works by luck, if VNC server TLS is not requested. The hash APIs avoids the need to litter the rest of the code with preprocessor checks and simplifies callers by allocating the correct amount of memory for the requested hash.

Since in some cases the real emit behavior may change, for example, qemu-img would not send a event, a callback layer is used to control the behavior.

* qemu-ga: Add Windows VSS provider and requester as DLLTomoki Sekiyama2013-09-091-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds VSS provider and requester as a qga-vss.dll, which is loaded by Windows VSS service as well as by qemu-ga. "provider.cpp" implements a basic stub of a software VSS provider. Currently, this module only relays a frozen event from VSS service to the agent, and thaw event from the agent to VSS service, to block VSS process to keep the system frozen while snapshots are taken at the host. To register the provider to the guest system as COM+ application, the type library (.tlb) for qga-vss.dll is required. To build it from COM IDL (.idl), VisualC++, MIDL and stdole2.tlb in Windows SDK are required. This patch also adds pre-compiled .tlb file in the repository in order to enable cross-compile qemu-ga.exe for Windows with VSS support. "requester.cpp" provides the VSS requester to kick the VSS snapshot process. Qemu-ga.exe works without the DLL, although fsfreeze features are disabled. These functions are only supported in Windows 2003 or later. In older systems, fsfreeze features are disabled. In several versions of Windows which don't support attribute VSS_VOLSNAP_ATTR_NO_AUTORECOVERY, DoSnapshotSet fails with error VSS_E_OBJECT_NOT_FOUND. In this patch, we just ignore this error. To solve this fundamentally, we need a framework to handle mount writable snapshot on guests, which is required by VSS auto-recovery feature (cleanup phase after a snapshot is taken).

* target-i386: Add "feature-words" property to X86CPUEduardo Habkost2013-05-061-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This property will be useful for libvirt, as libvirt already has logic based on low-level feature bits (not feature names), so it will be really easy to convert the current libvirt logic to something using the "feature-words" property. The property will have two main use cases: - Checking host capabilities, by checking the features of the "host" CPU model - Checking which features are enabled on each CPU model Example output: $ ./QMP/qmp --path=/tmp/m \ qom-get --path=/machine/icc-bridge/icc/child[0] \ --property=feature-words item[0].cpuid-register: EDX item[0].cpuid-input-eax: 2147483658 item[0].features: 0 item[1].cpuid-register: EAX item[1].cpuid-input-eax: 1073741825 item[1].features: 0 item[2].cpuid-register: EDX item[2].cpuid-input-eax: 3221225473 item[2].features: 0 item[3].cpuid-register: ECX item[3].cpuid-input-eax: 2147483649 item[3].features: 101 item[4].cpuid-register: EDX item[4].cpuid-input-eax: 2147483649 item[4].features: 563346425 item[5].cpuid-register: EBX item[5].cpuid-input-eax: 7 item[5].features: 0 item[5].cpuid-input-ecx: 0 item[6].cpuid-register: ECX item[6].cpuid-input-eax: 1 item[6].features: 2155880449 item[7].cpuid-register: EDX item[7].cpuid-input-eax: 1 item[7].features: 126614521 Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de>

* tpm: reorganize headers and split hardware partPaolo Bonzini2013-04-151-1/+1
| | | | | | | | | | | | | The TPM subsystem does not have a full front-end/back-end separation. The sole available backend, tpm_passthrough, depends on the data structures of the sole available frontend, tpm_tis. However, we can at least try to split the user interface (tpm.c) from the implementation (hw/tpm). The patches makes tpm.c not include tpm_int.h, which is shared between tpm_tis.c and tpm_passthrough.c; instead it moves more stuff to tpm_backend.h.

* configure: Don't fall back to gthread coroutine backendPeter Maydell2013-04-081-10/+1Star
| | | | | | | | | | | | | | | | | | The gthread coroutine backend is broken and does not produce a working QEMU; it is only useful for some very limited debugging situations. Clean up the backend selection logic in configure so that it now runs "if on windows use windows; else prefer ucontext; else sigaltstack". To do this we refactor the configure code to separate out "test whether we have a working ucontext", "pick a default if user didn't specify" and "validate that user didn't specify something invalid", rather than having all three of these run together. We also simplify the Makefile logic so it just links in the backend the configure script selects.

* Support for TPM command line optionsStefan Berger2013-03-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for TPM command line options. The command line options supported here are ./qemu-... -tpmdev passthrough,path=<path to TPM device>,id=<id> -device tpm-tis,tpmdev=<id>,id=<other id> and ./qemu-... -tpmdev help where the latter works similar to -soundhw help and shows a list of available TPM backends (for example 'passthrough'). Using the type parameter, the backend is chosen, i.e., 'passthrough' for the passthrough driver. The interpretation of the other parameters along with determining whether enough parameters were provided is pushed into the backend driver, which needs to implement the interface function 'create' and return a TPMDriverOpts structure if the VM can be started or 'NULL' if not enough or bad parameters were provided. Monitor support for 'info tpm' has been added. It for example prints the following: (qemu) info tpm TPM devices: tpm0: model=tpm-tis \ tpm0: type=passthrough,path=/dev/tpm0,cancel-path=/sys/devices/pnp0/00:09/cancel Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Reviewed-by: Corey Bryant <coreyb@linux.vnet.ibm.com> Reviewed-by: Joel Schopp <jschopp@linux.vnet.ibm.com> Message-id: 1361987275-26289-2-git-send-email-stefanb@linux.vnet.ibm.com Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
