2023-01-20include/block: Untangle inclusion loopsMarkus Armbruster2-0/+2
We have two inclusion loops: block/block.h -> block/block-global-state.h -> block/block-common.h -> block/blockjob.h -> block/block.h block/block.h -> block/block-io.h -> block/block-common.h -> block/blockjob.h -> block/block.h I believe these go back to Emanuele's reorganization of the block API, merged a few months ago in commit d7e2fe4aac8. Fortunately, breaking them is merely a matter of deleting unnecessary includes from headers, and adding them back in places where they are now missing.

2023-01-18bulk: Rename TARGET_FMT_plx -> HWADDR_FMT_plxPhilippe Mathieu-Daudé3-16/+16
The 'hwaddr' type is defined in "exec/hwaddr.h" as: hwaddr is the type of a physical address (its size can be different from 'target_ulong'). All definitions use the 'HWADDR_' prefix, except TARGET_FMT_plx: $ fgrep define include/exec/hwaddr.h #define HWADDR_H #define HWADDR_BITS 64 #define HWADDR_MAX UINT64_MAX #define TARGET_FMT_plx "%016" PRIx64 ^^^^^^ #define HWADDR_PRId PRId64 #define HWADDR_PRIi PRIi64 #define HWADDR_PRIo PRIo64 #define HWADDR_PRIu PRIu64 #define HWADDR_PRIx PRIx64 #define HWADDR_PRIX PRIX64 Since hwaddr's size can be *different* from target_ulong, it is very confusing to read one of its format using the 'TARGET_FMT_' prefix, normally used for the target_long / target_ulong types: $ fgrep TARGET_FMT_ include/exec/cpu-defs.h #define TARGET_FMT_lx "%08x" #define TARGET_FMT_ld "%d" #define TARGET_FMT_lu "%u" #define TARGET_FMT_lx "%016" PRIx64 #define TARGET_FMT_ld "%" PRId64 #define TARGET_FMT_lu "%" PRIu64 Apparently this format was missed during commit a8170e5e97 ("Rename target_phys_addr_t to hwaddr"), so complete it by doing a bulk-rename with: $ sed -i -e s/TARGET_FMT_plx/HWADDR_FMT_plx/g $(git grep -l TARGET_FMT_plx) Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> Message-Id: <20230110212947.34557-1-philmd@linaro.org> [thuth: Fix some warnings from checkpatch.pl along the way] Signed-off-by: Thomas Huth <thuth@redhat.com>

2022-12-14qapi run-state: Elide redundant has_FOO in generated CMarkus Armbruster1-13/+5

Tweak the semantic patch to drop redundant parenthesis around the return expression. Coccinelle drops a comment in hw/rdma/vmw/pvrdma_cmd.c; restored manually. Coccinelle messes up vmdk_co_create(), not sure why. Change dropped, will be done manually in the next commit. Line breaks in target/avr/cpu.h and hw/rdma/vmw/pvrdma_cmd.c tidied up manually. Whitespace in tools/virtiofsd/fuse_lowlevel.c tidied up manually. checkpatch.pl complains "return of an errno should typically be -ve" two times for hw/9pfs/9p-synth.c.

2022-11-06module: add Error arguments to module_load and module_load_qomClaudio Fontana1-1/+7
improve error handling during module load, by changing: bool module_load(const char *prefix, const char *lib_name); void module_load_qom(const char *type); to: int module_load(const char *prefix, const char *name, Error **errp); int module_load_qom(const char *type, Error **errp); where the return value is: -1 on module load error, and errp is set with the error 0 on module or one of its dependencies are not installed 1 on module load success 2 on module load success (module already loaded or built-in) module_load_qom_one has been introduced in: commit 28457744c345 ("module: qom module support"), which built on top of module_load_one, but discarded the bool return value. Restore it. Adapt all callers to emit errors, or ignore them, or fail hard, as appropriate in each context. Replace the previous emission of errors via fprintf in _some_ error conditions with Error and error_report, so as to emit to the appropriate target. A memory leak is also fixed as part of the module_load changes. audio: when attempting to load an audio module, report module load errors. Note that still for some callers, a single issue may generate multiple error reports, and this could be improved further. Regarding the audio code itself, audio_add() seems to ignore errors, and this should probably be improved. block: when attempting to load a block module, report module load errors. For the code paths that already use the Error API, take advantage of those to report module load errors into the Error parameter. For the other code paths, we currently emit the error, but this could be improved further by adding Error parameters to all possible code paths. console: when attempting to load a display module, report module load errors. qdev: when creating a new qdev Device object (DeviceState), report load errors. If a module cannot be loaded to create that device, now abort execution (if no CONFIG_MODULE) or exit (if CONFIG_MODULE). qom/object.c: when initializing a QOM object, or looking up class_by_name, report module load errors. qtest: when processing the "module_load" qtest command, report errors in the load of the module.

2022-10-28qapi: net: introduce a way to bypass qemu_opts_parse_noisily()Laurent Vivier1-1/+5
As qemu_opts_parse_noisily() flattens the QAPI structures ("type" field of Netdev structure can collides with "type" field of SocketAddress), we introduce a way to bypass qemu_opts_parse_noisily() and use directly visit_type_Netdev() to parse the backend parameters. More details from Markus: qemu_init() passes the argument of -netdev, -nic, and -net to net_client_parse(). net_client_parse() parses with qemu_opts_parse_noisily(), passing QemuOptsList qemu_netdev_opts for -netdev, qemu_nic_opts for -nic, and qemu_net_opts for -net. Their desc[] are all empty, which means any keys are accepted. The result of the parse (a QemuOpts) is stored in the QemuOptsList. Note that QemuOpts is flat by design. In some places, we layer non-flat on top using dotted keys convention, but not here. net_init_clients() iterates over the stored QemuOpts, and passes them to net_init_netdev(), net_param_nic(), or net_init_client(), respectively. These functions pass the QemuOpts to net_client_init(). They also do other things with the QemuOpts, which we can ignore here. net_client_init() uses the opts visitor to convert the (flat) QemOpts to a (non-flat) QAPI object Netdev. Netdev is also the argument of QMP command netdev_add. The opts visitor was an early attempt to support QAPI in (QemuOpts-based) CLI. It restricts QAPI types to a certain shape; see commit eb7ee2cbeb "qapi: introduce OptsVisitor". A more modern way to support QAPI is qobject_input_visitor_new_str(). It uses keyval_parse() instead of QemuOpts for KEY=VALUE,... syntax, and it also supports JSON syntax. The former isn't quite as expressive as JSON, but it's a lot closer than QemuOpts + opts visitor. This commit paves the way to use of the modern way instead.

2022-10-27vl: Allow ThreadContext objects to be created before the sandbox optionDavid Hildenbrand1-4/+32
Currently, there is no way to configure a CPU affinity inside QEMU when the sandbox option disables it for QEMU as a whole, for example, via: -sandbox enable=on,resourcecontrol=deny While ThreadContext objects can be created on the QEMU commandline and the CPU affinity can be configured externally via the thread-id, this is insufficient if a ThreadContext with a certain CPU affinity is already required during QEMU startup, before we can intercept QEMU and configure the CPU affinity. Blocking sched_setaffinity() was introduced in 24f8cdc57224 ("seccomp: add resourcecontrol argument to command line"), "to avoid any bigger of the process". However, we only care about once QEMU is running, not when the instance starting QEMU explicitly requests a certain CPU affinity on the QEMU comandline. Right now, for NUMA-aware preallocation of memory backends used for initial machine RAM, one has to: 1) Start QEMU with the memory-backend with "prealloc=off" 2) Pause QEMU before it starts the guest (-S) 3) Create ThreadContext, configure the CPU affinity using the thread-id 4) Configure the ThreadContext as "prealloc-context" of the memory backend 5) Trigger preallocation by setting "prealloc=on" To simplify this handling especially for initial machine RAM, allow creation of ThreadContext objects before parsing sandbox options, such that the CPU affinity requested on the QEMU commandline alongside the sandbox option can be set. As ThreadContext objects essentially only create a persistent context thread and set the CPU affinity, this is easily possible. With this change, we can create a ThreadContext with a CPU affinity on the QEMU commandline and use it for preallocation of memory backends glued to the machine (simplified example): To make "-name debug-threads=on" keep working as expected for the context threads, perform earlier parsing of "-name". qemu-system-x86_64 -m 1G \ -object thread-context,id=tc1,cpu-affinity=3-4 \ -object memory-backend-ram,id=pc.ram,size=1G,prealloc=on,prealloc-threads=2,prealloc-context=tc1 \ -machine memory-backend=pc.ram \ -S -monitor stdio -sandbox enable=on,resourcecontrol=deny And while we can query the current CPU affinity: (qemu) qom-get tc1 cpu-affinity [ 3, 4 ] We can no longer change it from QEMU directly: (qemu) qom-set tc1 cpu-affinity 1-2 Error: Setting CPU affinity failed: Operation not permitted Reviewed-by: Michal Privoznik <mprivozn@redhat.com> Message-Id: <20221014134720.168738-8-david@redhat.com> Signed-off-by: David Hildenbrand <david@redhat.com>

2022-10-26seccomp: Get actual errno value from failed seccomp functionsMichal Privoznik1-0/+13
Upon failure, a libseccomp API returns actual errno value very rarely. Fortunately, after its commit 34bf78ab (contained in 2.5.0 release), the SCMP_FLTATR_API_SYSRAWRC attribute can be set which makes subsequent APIs return true errno on failure. This is especially critical when seccomp_load() fails, because generic -ECANCELED says nothing.

2022-10-17qmp/hmp, device_tree.c: introduce dumpdtbDaniel Henrique Barboza1-0/+37
To save the FDT blob we have the '-machine dumpdtb=<file>' property. With this property set, the machine saves the FDT in <file> and exit. The created file can then be converted to plain text dts format using 'dtc'. There's nothing particularly sophisticated into saving the FDT that can't be done with the machine at any state, as long as the machine has a valid FDT to be saved. The 'dumpdtb' command receives a 'filename' parameter and, if the FDT is available via current_machine->fdt, save it in dtb format to 'filename'. In short, this is a '-machine dumpdtb' that can be fired on demand via QMP/HMP. This command will always be executed in-band (i.e. holding BQL), avoiding potential race conditions with machines that might change the FDT during runtime (e.g. PowerPC 'pseries' machine).

2022-09-23ui/cocoa: Run qemu_init in the main threadAkihiko Odaki2-6/+6
This work is based on: https://patchew.org/QEMU/20220317125534.38706-1-philippe.mathieu.daude@gmail.com/ Simplify the initialization dance by running qemu_init() in the main thread before the Cocoa event loop starts. The secondary thread only runs only qemu_main_loop() and qemu_cleanup(). This fixes a case where addRemovableDevicesMenuItems() calls qmp_query_block() while expecting the main thread to still hold the BQL. Overriding the code after calling qemu_init() is done by dynamically replacing a function pointer variable, qemu_main when initializing ui/cocoa, which unifies the static implementation of main() for builds with ui/cocoa and ones without ui/cocoa.

2022-09-13semihosting: Allow optional use of semihosting from userspacePeter Maydell1-1/+1
Currently our semihosting implementations generally prohibit use of semihosting calls in system emulation from the guest userspace. This is a very long standing behaviour justified originally "to provide some semblance of security" (since code with access to the semihosting ABI can do things like read and write arbitrary files on the host system). However, it is sometimes useful to be able to run trusted guest code which performs semihosting calls from guest userspace, notably for test code. Add a command line suboption to the existing semihosting-config option group so that you can explicitly opt in to semihosting from guest userspace with -semihosting-config userspace=on (There is no equivalent option for the user-mode emulator, because there by definition all code runs in userspace and has access to semihosting already.) This commit adds the infrastructure for the command line option and adds a bool 'is_user' parameter to the function semihosting_userspace_enabled() that target code can use to check whether it should be permitting the semihosting call for userspace. It mechanically makes all the callsites pass 'false', so they continue checking "is semihosting enabled in general". Subsequent commits will make each target that implements semihosting honour the userspace=on option by passing the correct value and removing whatever "don't do this for userspace" checking they were doing by hand.
