2016-09-20qemu-img: add the 'dd' subcommandReda Sallahi10-5/+584
This patch adds a basic dd subcommand analogous to dd(1) to qemu-img. For the start, this implements the bs, if, of and count options and requires both if and of to be specified (no stdin/stdout if not specified) and doesn't support tty, pipes, etc. The image format must be specified with -O for the output if the raw format is not the intended one. Two tests are added to test qemu-img dd.

2016-09-19qapi: check invalid arguments on no-args commandsMarc-André Lureau2-15/+58
The generated marshal functions do not visit arguments from commands that take no arguments. Thus they fail to catch invalid members. Visit the arguments, if provided, to throw an error in case of invalid members. Currently, qmp_check_client_args() checks for invalid arguments and correctly catches this case. When switching to qmp_dispatch() we want to keep that behaviour. The commands using 'O' may have arbitrary arguments, and must have 'gen': false in the qapi schema to skip the generated checks. Old/new diff: void qmp_marshal_stop(QDict *args, QObject **ret, Error **errp) { Error *err = NULL; + Visitor *v = NULL; - (void)args; + if (args) { + v = qmp_input_visitor_new(QOBJECT(args), true); + visit_start_struct(v, NULL, NULL, 0, &err); + if (err) { + goto out; + } + + if (!err) { + visit_check_struct(v, &err); + } + visit_end_struct(v, NULL); + if (err) { + goto out; + } + } qmp_stop(&err); + +out: error_propagate(errp, err); + visit_free(v); + if (args) { + v = qapi_dealloc_visitor_new(); + visit_start_struct(v, NULL, NULL, 0, NULL); + + visit_end_struct(v, NULL); + visit_free(v); + } } The new code closely resembles code for a command with arguments. Differences: - the visit of the argument and its cleanup struct don't visit any members (because there are none). - the visit of the argument struct and its cleanup are conditional.

2016-09-19qmp: Hack to keep commands configuration-specificMarc-André Lureau1-0/+35
We currently define QMP commands in two places: the QAPI schema and qmp-commands.hx. The latter is preprocessed, the former is not. We use the preprocessor to suppress configuration-specific commands. For instance, query-spice is only available #ifdef CONFIG_SPICE. QMP command dispatch and query-commands use the qmp-commands.hx definition, and thus obey the #ifdeffery there. Good, because it lets QMP clients probe for available features more easily. query-qmp-schema uses the QAPI schema, and thus lists the configuration-specific commands even when they're unavailable. Not so good. We're about to flip command dispatch and query-commands to the non-middle-mode command registry, which uses the QAPI schema, so we can ditch qmp-commands.hx. To avoid regressing query-commands, arrange for commands that are suppressed with the preprocessor now to be unregistered with that registry. This will keep them unavailable and out of query-commands when we flip command dispatch and query-commands to that registry, exactly as before. This is a hack. The proper solution is to support configuration-specific commands in the QAPI schema. Mark it FIXME.

2016-09-19crypto: use correct derived key size when timing pbkdfDaniel P. Berrange4-4/+15
Currently when timing the pbkdf algorithm a fixed key size of 32 bytes is used. This results in inaccurate timings for certain hashes depending on their digest size. For example when using sha1 with aes-256, this causes us to measure time for the master key digest doing 2 sha1 operations per iteration, instead of 1. Instead we should pass in the desired key size to the timing routine that matches the key size that will be used for real later. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P.

2016-09-19crypto: make PBKDF iterations configurable for LUKS formatDaniel P. Berrange3-1/+35
As protection against bruteforcing passphrases, the PBKDF algorithm is tuned by counting the number of iterations needed to produce 1 second of running time. If the machine that the image will be used on is much faster than the machine where the image is created, it can be desirable to raise the number of iterations. This change adds a new 'iter-time' property that allows the user to choose the iteration wallclock time. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P.

2016-09-19crypto: use uint64_t for pbkdf iteration count parametersDaniel P. Berrange6-40/+57
The qcrypto_pbkdf_count_iters method uses a 64 bit int but then checks its value against INT32_MAX before returning it. This bounds check is premature, because the calling code may well scale the iteration count by some value. It is thus better to return a 64-bit integer and let the caller do range checking. For consistency the qcrypto_pbkdf method is also changed to accept a 64bit int, though this is somewhat academic since nettle is limited to taking an 'int' while gcrypt is limited to taking a 'long int'.

2016-09-199pfs: fix potential segfault during walkGreg Kurz1-2/+3
If the call to fid_to_qid() returns an error, we will call v9fs_path_free() on uninitialized paths. It is a regression introduced by the following commit: 56f101ecce0e 9pfs: handle walk of ".." in the root directory Let's fix this by initializing dpath and path before calling fid_to_qid().

2016-09-16MAINTAINERS: add virtio-* testsGreg Kurz1-0/+7
Except virtio-9p, all virtio-* tests are orphan. This patch tries to fix it, according to the following logic: - when the related subsystem has its own section in MAINTAINERS, the test is added there - otherwise it is added to the "parent" section (aka.

2016-09-16tcg: Optimize fence instructionsPranith Kumar1-0/+39
This commit optimizes fence instructions. Two optimizations are currently implemented: (1) unnecessary duplicate fence instructions, and (2) merging weaker fences into a stronger fence. [rth: Merge tcg_optimize_mb back into tcg_optimize, so that we only loop over the opcode stream once. Merge "unrelated" weaker barriers into one stronger barrier.] Signed-off-by: Pranith Kumar <bobby.prani@gmail.com> Message-Id: <20160823134825.32578-1-bobby.prani@gmail.com> Signed-off-by: Richard Henderson <rth@twiddle.net>
