Markus Armbruster	b1019999e8	qapi/cryptodev: Rename QCryptodevBackendAlgType to *Algo, and drop prefix QAPI's 'prefix' feature can make the connection between enumeration type and its constants less than obvious. It's best used with restraint. QCryptodevBackendAlgType has a 'prefix' that overrides the generated enumeration constants' prefix to QCRYPTODEV_BACKEND_ALG. We could simply drop 'prefix', but I think the abbreviation "alg" is less than clear. Additionally rename the type to QCryptodevBackendAlgoType. The prefix becomes QCRYPTODEV_BACKEND_ALGO_TYPE.

zhenwei pi	0e660a6f90	crypto: Introduce RSA algorithm There are two parts in this patch: 1, support akcipher service by cryptodev-builtin driver 2, virtio-crypto driver supports akcipher service In principle, we should separate this into two patches, to avoid compiling error, merge them into one. Then virtio-crypto gets request from guest side, and forwards the request to builtin driver to handle it. Test with a guest linux: 1, The self-test framework of crypto layer works fine in guest kernel 2, Test with Linux guest(with asym support), the following script test(note that pkey_XXX is supported only in a newer version of keyutils): - both public key & private key - create/close session - encrypt/decrypt/sign/verify basic driver operation - also test with kernel crypto layer(pkey add/query) All the cases work fine.

Markus Armbruster	d2623129a7	qom: Drop parameter @errp of object_property_add() & friends The only way object_property_add() can fail is when a property with the same name already exists. Since our property names are all hardcoded, failure is a programming error, and the appropriate way to handle it is passing &error_abort. Same for its variants, except for object_property_add_child(), which additionally fails when the child already has a parent. Parentage is also under program control, so this is a programming error, too. We have a bit over 500 callers. Almost half of them pass &error_abort, slightly fewer ignore errors, one test case handles errors, and the remaining few callers pass them to their own callers. The previous few commits demonstrated once again that ignoring programming errors is a bad idea. Of the few ones that pass on errors, several violate the Error API. The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. ich9_pm_add_properties(), sparc32_ledma_realize(), sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize() are wrong that way. When the one appropriate choice of argument is &error_abort, letting users pick the argument is a bad idea. Drop parameter @errp and assert the preconditions instead. There's one exception to "duplicate property name is a programming error": the way object_property_add() implements the magic (and undocumented) "automatic arrayification". Don't drop @errp there. Instead, rename object_property_add() to object_property_try_add(), and add the obvious wrapper object_property_add().

Markus Armbruster	9af2398977	Include less of the generated modular QAPI headers In my "build everything" tree, a change to the types in qapi-schema.json triggers a recompile of about 4800 out of 5100 objects. The previous commit split up qmp-commands.h, qmp-event.h, qmp-visit.h, qapi-types.h. Each of these headers still includes all its shards. Reduce compile time by including just the shards we actually need. To illustrate the benefits: adding a type to qapi/migration.json now recompiles some 2300 instead of 4800 objects. The next commit will improve it further.
