2021-03-12tests: Move unit tests into a separate directoryThomas Huth1-1046/+0
The main tests directory still looks very crowded, and it's not clear which files are part of a unit tests and which belong to a different test subsystem. Let's clean up the mess and move the unit tests to a separate directory.

2021-01-23qemu-option: warn for short-form boolean optionsPaolo Bonzini1-1/+1
Options such as "server" or "nowait", that are commonly found in -chardev, are sugar for "server=on" and "wait=off". This is quite surprising and also does not have any notion of typing attached. It is even possible to do "-device e1000,noid" and get a device with "id=off". Deprecate it and print a warning when it is encountered. In general, this short form for boolean options only seems to be in wide use for -chardev and -spice. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2020-12-10qemu-option: restrict qemu_opts_set to merge-lists QemuOptsPaolo Bonzini1-3/+17
qemu_opts_set is used to create default network backends and to parse sugar options -kernel, -initrd, -append, -bios and -dtb. These are very different uses: I would *expect* a function named qemu_opts_set to set an option in a merge-lists QemuOptsList, such as -kernel, and possibly to set an option in a non-merge-lists QemuOptsList with non-NULL id, similar to -set. However, it wouldn't *work* to use qemu_opts_set for the latter because qemu_opts_set uses fail_if_exists==1. So, for non-merge-lists QemuOptsList and non-NULL id, the semantics of qemu_opts_set (fail if the (QemuOptsList, id) pair already exists) are debatable. On the other hand, I would not expect qemu_opts_set to create a non-merge-lists QemuOpts with a single option; which it does, though. For this case of non-merge-lists QemuOptsList and NULL id, qemu_opts_set hardly adds value over qemu_opts_parse. It does skip some parsing and unescaping, but that's not needed when creating default network backends. So qemu_opts_set has warty behavior for non-merge-lists QemuOptsList if id is non-NULL, and it's mostly pointless if id is NULL. My solution to keeping the API as simple as possible is to limit qemu_opts_set to merge-lists QemuOptsList. For them, it's useful (we don't want comma-unescaping for -kernel) *and* has sane semantics. Network backend creation is switched to qemu_opts_parse. qemu_opts_set is now only used on merge-lists QemuOptsList... except in the testcase, which is changed to use a merge-list QemuOptsList. With this change we can also remove the id parameter. With the parameter always NULL, we know that qemu_opts_create cannot fail and can pass &error_abort to it.

2018-05-09opts: don't silently truncate long parameter keysDaniel P. Berrangé1-18/+0
The existing QemuOpts parsing code uses a fixed size 128 byte buffer for storing the parameter keys. If a key exceeded this size it was silently truncate and no error reported to the user. This behaviour was reasonable & harmless because traditionally the key names are all statically declared, and it was known that no code was declaring a key longer than 127 bytes. This assumption, however, ceased to be valid once the block layer added support for dot-separate compound keys. This syntax allows for keys that can be arbitrarily long, limited only by the number of block drivers you can stack up. With this usage, silently truncating the key name can never lead to correct behaviour. Hopefully such truncation would turn into an error, when the block code then tried to extract options later, but there's no guarantee that will happen. It is conceivable that an option specified by the user may be truncated and then ignored. This could have serious consequences, possibly even leading to security problems if the ignored option set a security relevant parameter. If the operating system didn't limit the user's argv when spawning QEMU, the code should honour whatever length arguments were given without imposing its own length restrictions. This patch thus changes the code to use a heap allocated buffer for storing the keys during parsing, lifting the arbitrary length restriction. Signed-off-by: Daniel P.

2018-05-04qobject: Replace qobject_incref/QINCREF qobject_decref/QDECREFMarc-André Lureau1-7/+7
Now that we can safely call QOBJECT() on QObject * as well as its subtypes, we can have macros qobject_ref() / qobject_unref() that work everywhere instead of having to use QINCREF() / QDECREF() for QObject and qobject_incref() / qobject_decref() for its subtypes. The replacement is mechanical, except I broke a long line, and added a cast in monitor_qmp_cleanup_req_queue_locked(). Unlike qobject_decref(), qobject_unref() doesn't accept void *. Note that the new macros evaluate their argument exactly once, thus no need to shout them.

2016-03-22include/qemu/osdep.h: Don't include qapi/error.hMarkus Armbruster1-0/+1
Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little.

2015-06-22QemuOpts: Wean off qerror_report_err()Markus Armbruster1-1/+1
qerror_report_err() is a transitional interface to help with converting existing monitor commands to QMP. It should not be used elsewhere. The only remaining user in qemu-option.c is qemu_opts_parse(). Is it used in QMP context? If not, we can simply replace qerror_report_err() by error_report_err(). The uses in qemu-img.c, qemu-io.c, qemu-nbd.c and under tests/ are clearly not in QMP context. The uses in vl.c aren't either, because the only QMP command handlers there are qmp_query_status() and qmp_query_machines(), and they don't call it. Remaining uses: * drive_def(): Command line -drive and such, HMP drive_add and pci_add * hmp_chardev_add(): HMP chardev-add * monitor_parse_command(): HMP core * tmp_config_parse(): Command line -tpmdev * net_host_device_add(): HMP host_net_add * net_client_parse(): Command line -net and -netdev * qemu_global_option(): Command line -global * vnc_parse_func(): Command line -display, -vnc, default display, HMP change, QMP change. Bummer. * qemu_pci_hot_add_nic(): HMP pci_add * usb_net_init(): Command line -usbdevice, HMP usb_add Propagate errors through qemu_opts_parse(). Create a convenience function qemu_opts_parse_noisily() that passes errors to error_report_err(). Switch all non-QMP users outside tests to it. That leaves vnc_parse_func().
