2022-12-15util/qemu-config: Fix "query-command-line-options" to provide the right valuesThomas Huth1-91/+75
The "query-command-line-options" command uses a hand-crafted list of options that should be returned for the "machine" parameter. This is pretty much out of sync with reality, for example settings like "kvm_shadow_mem" or "accel" are not parameters for the machine anymore. Also, there is no distinction between the targets here, so e.g. the s390x-specific values like "loadparm" in this list also show up with the other targets like x86_64. Let's fix this now by geting rid of the hand-crafted list and by querying the properties of the machine classes instead to assemble the list.

2022-12-14qapi misc: Elide redundant has_FOO in generated CMarkus Armbruster1-12/+5
The has_FOO for pointer-valued FOO are redundant, except for arrays. They are also a nuisance to work with. Recent commit "qapi: Start to elide redundant has_FOO in generated C" provided the means to elide them step by step. This is the step for qapi/misc.json. Said commit explains the transformation in more detail. The invariant violations mentioned there do not occur here.

2022-04-28remove -writeconfigPaolo Bonzini1-42/+0
Like -set and -readconfig, it would not really be too hard to extend -writeconfig to parsing mechanisms other than QemuOpts. However, the uses of -writeconfig are substantially more limited, as it is generally easier to write the configuration by hand in the first place. In addition, -writeconfig does not even try to detect cases where it prints incorrect syntax (for example if values have a quote in them, since qemu_config_parse does not support any kind of escaping.

Commit d8fb7d0969d5c32b3d1b9e20b63ec6c0abe80be4 ("vl: switch -M parsing to keyval") stopped adding the "machine" QemuOptsList. This causes "machine" options to not show up in QMP query-command-line-options output. For example, libvirt cannot detect that kernel_irqchip support is available.

The leak is basically impossible to reach, since the only common way to get ferror(fp) is by passing a directory to -readconfig. In that case, the error occurs before qdict is set to anything non-NULL. However, it's theoretically possible to get there after an EIO.

2021-06-15qemu-config: use qemu_opts_from_qdictPaolo Bonzini1-16/+1
Using qemu_opts_absorb_qdict, and then checking for any leftover options, is redundant because there is already a function that does the same, qemu_opts_from_qdict. qemu_opts_from_qdict consumes the whole dictionary and therefore can just return an error message if an option fails to validate. This also fixes a bug, because the "id" entry was retrieved in qemu_config_do_parse and then left there by qemu_opts_absorb_qdict. As a result, it was reported as an unrecognized option.

2021-06-04qemu-config: parse configuration files to a QDictPaolo Bonzini1-30/+68
Change the parser to put the values into a QDict and pass them to a callback. qemu_config_parse's QemuOpts creation is itself turned into a callback function. This is useful for -readconfig to support keyval-based options; getting a QDict from the parser removes a roundtrip from QDict to QemuOpts and then back to QDict. Unfortunately there is a disadvantage in that semantic errors will point to the last line of the group, because the entries of the QDict do not have a location attached.

2020-12-19qapi: Use QAPI_LIST_PREPEND() where possibleEric Blake1-10/+4
Anywhere we create a list of just one item or by prepending items (typically because order doesn't matter), we can use QAPI_LIST_PREPEND(). But places where we must keep the list in order by appending remain open-coded until later patches. Note that as a side effect, this also performs a cleanup of two minor issues in qga/commands-posix.c: the old code was performing new = g_malloc0(sizeof(*ret)); which 1) is confusing because you have to verify whether 'new' and 'ret' are variables with the same type, and 2) would conflict with C++ compilation (not an actual problem for this file, but makes copy-and-paste harder).

2020-07-10error: Eliminate error_propagate() with Coccinelle, part 1Markus Armbruster1-5/+2
When all we do with an Error we receive into a local variable is propagating to somewhere else, we can just as well receive it there right away. Convert if (!foo(..., &err)) { ... error_propagate(errp, err); ... return ... } to if (!foo(..., errp)) { ... ... return ... } where nothing else needs @err. Coccinelle script: @rule1 forall@ identifier fun, err, errp, lbl; expression list args, args2; binary operator op; constant c1, c2; symbol false; @@ if ( ( - fun(args, &err, args2) + fun(args, errp, args2) | - !fun(args, &err, args2) + !fun(args, errp, args2) | - fun(args, &err, args2) op c1 + fun(args, errp, args2) op c1 ) ) { ... when != err when != lbl: when strict - error_propagate(errp, err); ... when != err ( return; | return c2; | return false; ) } @rule2 forall@ identifier fun, err, errp, lbl; expression list args, args2; expression var; binary operator op; constant c1, c2; symbol false; @@ - var = fun(args, &err, args2); + var = fun(args, errp, args2); ... when != err if ( ( var | !var | var op c1 ) ) { ... when != err when != lbl: when strict - error_propagate(errp, err); ... when != err ( return; | return c2; | return false; | return var; ) } @depends on rule1 || rule2@ identifier err; @@ - Error *err = NULL; ... when != err Not exactly elegant, I'm afraid. The "when != lbl:" is necessary to avoid transforming if (fun(args, &err)) { goto out } ... out: error_propagate(errp, err); even though other paths to label out still need the error_propagate(). For an actual example, see sclp_realize(). Without the "when strict", Coccinelle transforms vfio_msix_setup(), incorrectly. I don't know what exactly "when strict" does, only that it helps here. The match of return is narrower than what I want, but I can't figure out how to express "return where the operand doesn't use @err". For an example where it's too narrow, see vfio_intx_enable(). Silently fails to convert hw/arm/armsse.c, because Coccinelle gets confused by ARMSSE being used both as typedef and function-like macro there. Converted manually. Line breaks tidied up manually. One nested declaration of @local_err deleted manually. Preexisting unwanted blank line dropped in hw/riscv/sifive_e.c.

2018-06-15block: Add block-specific QDict headerMax Reitz1-0/+1
There are numerous QDict functions that have been introduced for and are used only by the block layer. Move their declarations into an own header file to reflect that. While qdict_extract_subqdict() is in fact used outside of the block layer (in util/qemu-config.c), it is still a function related very closely to how the block layer works with nested QDicts, namely by sometimes flattening them. Therefore, its declaration is put into this header as well and util/qemu-config.c includes it with a comment stating exactly which function it needs.

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 *.

The previous commit improved compile time by including less of the generated QAPI headers.

2017-10-09config: qemu_config_parse() return number of config groupsEduardo Habkost1-8/+7
Change qemu_config_parse() to return the number of config groups in success and -EINVAL on error. This will allow callers of qemu_config_parse() to check if something was really loaded from the config file. All existing callers of qemu_config_parse() and qemu_read_config_file() only check if the return value was negative, so the change shouldn't affect them.

2016-10-07block: Add bdrv_runtime_opts to query-command-line-optionsKevin Wolf1-1/+1
Recently we moved a few options from QemuOptsLists in blockdev.c to bdrv_runtime_opts in block.c in order to make them accissble using blockdev-add. However, this has the side effect that these options are missing from query-command-line-options now, and libvirt consequently disables the corresponding feature. This problem was reported as a regression for the 'discard' option, introduced in commit 818584a4. However, it is more general than that. Fix it by adding bdrv_runtime_opts to the list of QemuOptsLists that are returned in query-command-line-options. For the future, libvirt is advised to use QMP schema introspection for block device options.

2015-06-09QemuOpts: Drop qemu_opt_foreach() parameter abort_on_failureMarkus Armbruster1-1/+1
When the argument is non-zero, qemu_opt_foreach() stops on callback returning non-zero, and returns that value. When the argument is zero, it doesn't stop, and returns the callback's value from the last iteration. The two callers that pass zero could just as well pass one: * qemu_spice_init()'s callback add_channel() either returns zero or exit()s. * config_write_opts()'s callback config_write_opt() always returns zero. Drop the parameter, and always stop. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>

Currently it is impossible to set an option in a config file to an empty string, because the parser matches only lines containing non-empty strings between double-quotes. As sscanf() "[" conversion specifier only matches non-empty strings, add a special case for empty strings.

Commit 49d2e64 (machine: remove qemu_machine_opts global list) made machine options specific to machine sub-type, leaving the qemu_machine_opts desc array empty. Sadly this is the place qmp_query_command_line_options is looking for supported options. As a fix for for 2.3 the machine_qemu_opts (the generic ones) are restored only for qemu-config scope. We need to find a better fix for 2.4.

2015-02-26QemuOpts: Drop qemu_opt_set(), rename qemu_opt_set_err(), fix useMarkus Armbruster1-2/+7
qemu_opt_set() is a wrapper around qemu_opt_set() that reports the error with qerror_report_err(). Most of its users assume the function can't fail. Make them use qemu_opt_set_err() with &error_abort, so that should the assumption ever break, it'll break noisily. Just two users remain, in util/qemu-config.c. Switch them to qemu_opt_set_err() as well, then rename qemu_opt_set_err() to qemu_opt_set(). Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>
