2020-07-10error: Eliminate error_propagate() with Coccinelle, part 1Markus Armbruster1-3/+1
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.

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.

2020-07-10error: Avoid unnecessary error_propagate() after error_setg()Markus Armbruster1-6/+4
Replace error_setg(&err, ...); error_propagate(errp, err); by error_setg(errp, ...); Related pattern: if (...) { error_setg(&err, ...); goto out; } ... out: error_propagate(errp, err); return; When all paths to label out are that way, replace by if (...) { error_setg(errp, ...); return; } and delete the label along with the error_propagate(). When we have at most one other path that actually needs to propagate, and maybe one at the end that where propagation is unnecessary, e.g. foo(..., &err); if (err) { goto out; } ... bar(..., &err); out: error_propagate(errp, err); return; move the error_propagate() to where it's needed, like if (...) { foo(..., &err); error_propagate(errp, err); return; } ... bar(..., errp); return; and transform the error_setg() as above. In some places, the transformation results in obviously unnecessary error_propagate(). The next few commits will eliminate them. Bonus: the elimination of gotos will make later patches in this series easier to review.

2020-05-15qom: Drop parameter @errp of object_property_add() & friendsMarkus Armbruster1-2/+2
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().

2016-07-19qapi: Change Netdev into a flat unionEric Blake1-3/+3
This is a mostly-mechanical conversion that creates a new flat union 'Netdev' QAPI type that covers all the branches of the former 'NetClientOptions' simple union, where the branches are now listed in a new 'NetClientDriver' enum rather than generated from the simple union. The existence of a flat union has no change to the command line syntax accepted for new code, and will make it possible for a future patch to switch the QMP command to parse a boxed union for no change to valid QMP; but it does have some ripple effect on the C code when dealing with the new types. While making the conversion, note that the 'NetLegacy' type remains unchanged: it applies only to legacy command line options, and will not be ported to QMP, so it should remain a wrapper around a simple union; to avoid confusion, the type named 'NetClientOptions' is now gone, and we introduce 'NetLegacyOptions' in its place. Then, in the C code, we convert from NetLegacy to Netdev as soon as possible, so that the bulk of the net stack only has to deal with one QAPI type, not two. Note that since the old legacy code always rejected 'hubport', we can just omit that branch from the new 'NetLegacyOptions' simple union.

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.

2016-03-18qapi: Don't special-case simple union wrappersEric Blake1-1/+1
Simple unions were carrying a special case that hid their 'data' QMP member from the resulting C struct, via the hack method QAPISchemaObjectTypeVariant.simple_union_type(). But by using the work we started by unboxing flat union and alternate branches, coupled with the ability to visit the members of an implicit type, we can now expose the simple union's implicit type in qapi-types.h: | struct q_obj_ImageInfoSpecificQCow2_wrapper { | ImageInfoSpecificQCow2 *data; | }; | | struct q_obj_ImageInfoSpecificVmdk_wrapper { | ImageInfoSpecificVmdk *data; | }; ... | struct ImageInfoSpecific { | ImageInfoSpecificKind type; | union { /* union tag is @type */ | void *data; |- ImageInfoSpecificQCow2 *qcow2; |- ImageInfoSpecificVmdk *vmdk; |+ q_obj_ImageInfoSpecificQCow2_wrapper qcow2; |+ q_obj_ImageInfoSpecificVmdk_wrapper vmdk; | } u; | }; Doing this removes asymmetry between QAPI's QMP side and its C side (both sides now expose 'data'), and means that the treatment of a simple union as sugar for a flat union is now equivalent in both languages (previously the two approaches used a different layer of dereferencing, where the simple union could be converted to a flat union with equivalent C layout but different {} on the wire, or to an equivalent QMP wire form but with different C representation). Using the implicit type also lets us get rid of the simple_union_type() hack. Of course, now all clients of simple unions have to adjust from using su->u.member to using su->u.member.data; while this touches a number of files in the tree, some earlier cleanup patches helped minimize the change to the initialization of a temporary variable rather than every single member access. The generated qapi-visit.c code is also affected by the layout change: |@@ -7393,10 +7393,10 @@ void visit_type_ImageInfoSpecific_member | } | switch (obj->type) { | case IMAGE_INFO_SPECIFIC_KIND_QCOW2: |- visit_type_ImageInfoSpecificQCow2(v, "data", &obj->u.qcow2, &err); |+ visit_type_q_obj_ImageInfoSpecificQCow2_wrapper_members(v, &obj->u.qcow2, &err); | break; | case IMAGE_INFO_SPECIFIC_KIND_VMDK: |- visit_type_ImageInfoSpecificVmdk(v, "data", &obj->u.vmdk, &err); |+ visit_type_q_obj_ImageInfoSpecificVmdk_wrapper_members(v, &obj->u.vmdk, &err); | break; | default: | abort(); Signed-off-by: Eric Blake <eblake@redhat.com> Message-Id: <1458254921-17042-13-git-send-email-eblake@redhat.com> Signed-off-by: Markus Armbruster <armbru@redhat.com>

2016-02-08qapi: Swap visit_* arguments for consistent 'name' placementEric Blake1-2/+2
JSON uses "name":value, but many of our visitor interfaces were called with visit_type_FOO(v, &value, name, errp). This can be a bit confusing to have to mentally swap the parameter order to match JSON order. It's particularly bad for visit_start_struct(), where the 'name' parameter is smack in the middle of the otherwise-related group of 'obj, kind, size' parameters! It's time to do a global swap of the parameter ordering, so that the 'name' parameter is always immediately after the Visitor argument. Additional reason in favor of the swap: the existing include/qjson.h prefers listing 'name' first in json_prop_*(), and I have plans to unify that file with the qapi visitors; listing 'name' first in qapi will minimize churn to the (admittedly few) qjson.h clients. Later patches will then fix docs, object.h, visitor-impl.h, and those clients to match. Done by first patching scripts/qapi*.py by hand to make generated files do what I want, then by running the following Coccinelle script to affect the rest of the code base: $ spatch --sp-file script `git grep -l '\bvisit_' -- '**/*.[ch]'` I then had to apply some touchups (Coccinelle insisted on TAB indentation in visitor.h, and botched the signature of visit_type_enum() by rewriting 'const char *const strings[]' to the syntactically invalid 'const char*const[] strings'). The movement of parameters is sufficient to provoke compiler errors if any callers were missed. // Part 1: Swap declaration order @@ type TV, TErr, TObj, T1, T2; identifier OBJ, ARG1, ARG2; @@ void visit_start_struct -(TV v, TObj OBJ, T1 ARG1, const char *name, T2 ARG2, TErr errp) +(TV v, const char *name, TObj OBJ, T1 ARG1, T2 ARG2, TErr errp) { ... } @@ type bool, TV, T1; identifier ARG1; @@ bool visit_optional -(TV v, T1 ARG1, const char *name) +(TV v, const char *name, T1 ARG1) { ... } @@ type TV, TErr, TObj, T1; identifier OBJ, ARG1; @@ void visit_get_next_type -(TV v, TObj OBJ, T1 ARG1, const char *name, TErr errp) +(TV v, const char *name, TObj OBJ, T1 ARG1, TErr errp) { ... } @@ type TV, TErr, TObj, T1, T2; identifier OBJ, ARG1, ARG2; @@ void visit_type_enum -(TV v, TObj OBJ, T1 ARG1, T2 ARG2, const char *name, TErr errp) +(TV v, const char *name, TObj OBJ, T1 ARG1, T2 ARG2, TErr errp) { ... } @@ type TV, TErr, TObj; identifier OBJ; identifier VISIT_TYPE =~ "^visit_type_"; @@ void VISIT_TYPE -(TV v, TObj OBJ, const char *name, TErr errp) +(TV v, const char *name, TObj OBJ, TErr errp) { ... } // Part 2: swap caller order @@ expression V, NAME, OBJ, ARG1, ARG2, ERR; identifier VISIT_TYPE =~ "^visit_type_"; @@ ( -visit_start_struct(V, OBJ, ARG1, NAME, ARG2, ERR) +visit_start_struct(V, NAME, OBJ, ARG1, ARG2, ERR) | -visit_optional(V, ARG1, NAME) +visit_optional(V, NAME, ARG1) | -visit_get_next_type(V, OBJ, ARG1, NAME, ERR) +visit_get_next_type(V, NAME, OBJ, ARG1, ERR) | -visit_type_enum(V, OBJ, ARG1, ARG2, NAME, ERR) +visit_type_enum(V, NAME, OBJ, ARG1, ARG2, ERR) | -VISIT_TYPE(V, OBJ, NAME, ERR) +VISIT_TYPE(V, NAME, OBJ, ERR) ) Signed-off-by: Eric Blake <eblake@redhat.com> Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-Id: <1454075341-13658-19-git-send-email-eblake@redhat.com> Signed-off-by: Markus Armbruster <armbru@redhat.com>

2015-11-02net: Convert to new qapi union layoutEric Blake1-2/+2
We have two issues with our qapi union layout: 1) Even though the QMP wire format spells the tag 'type', the C code spells it 'kind', requiring some hacks in the generator. 2) The C struct uses an anonymous union, which places all tag values in the same namespace as all non-variant members. This leads to spurious collisions if a tag value matches a non-variant member's name. Make the conversion to the new layout for net-related code.

2015-05-27net/dump: Improve -net/host_net_add dump error reportingMarkus Armbruster1-6/+6
When -net dump fails, it first reports a specific error, then a generic one, like this: $ qemu-system-x86_64 -net dump,id=foo,file=/eperm qemu-system-x86_64: -net dump,id=foo,file=/eperm: -net dump: can't open /eperm qemu-system-x86_64: -net dump,id=foo,file=/eperm: Device 'dump' could not be initialized Convert net_init_tap() to Error.

2015-05-27net: Permit incremental conversion of init functions to ErrorMarkus Armbruster1-1/+2
Error reporting for netdev_add is broken: the net_client_init_fun[] report the actual errors with (at best) error_report(), and their caller net_client_init1() makes up a generic error on top. For command line and HMP, this produces an mildly ugly error cascade. In QMP, the actual errors go to stderr, and the generic error becomes the command's error reply. To fix this, we need to convert the net_client_init_fun[] to Error. To permit fixing them one by one, add an Error ** parameter to the net_client_init_fun[]. If the call fails without returning an Error, make up the same generic Error as before. But if it returns one, use that instead. Since none of them does so far, no functional change.

2012-10-08net: consolidate NetClientState header files into onePaolo Bonzini1-1/+1
This patch doesn't seem much useful alone, I must admit. However, it makes sense as part of the upcoming directory reorganization, where I want to have include/net/tap.h as the net<->hw interface for tap. Then having both net/tap.h and include/net/tap.h does not work. "Fixed" by moving all the init functions to a single header file net/clients.h. The patch also adopts a uniform style for including net/*.h files from net/*.c, without the net/ path.

2012-08-01net: Rename VLANClientState to NetClientStateStefan Hajnoczi1-6/+6
The vlan feature is no longer part of net core. Rename VLANClientState to NetClientState because net clients are not explicitly associated with a vlan at all, instead they have a peer net client to which they are connected. This patch is a mechanical search-and-replace except for a few whitespace fixups where changing VLANClientState to NetClientState misaligned whitespace.

2012-07-23convert net_client_init() to OptsVisitorLaszlo Ersek1-1/+2
The net_client_init() prototype is kept intact. Based on "is_netdev", the QemuOpts-rooted QemuOpt-list is parsed as a Netdev or a NetLegacy. The original meat of net_client_init() is moved to and simplified in net_client_init1(): Fields not common between -net and -netdev are clearly separated. Getting the name for the init functions is cleaner: Netdev::id is mandatory, and all init functions handle a NULL NetLegacy::name. NetLegacy::vlan explicitly depends on -net (see below). Verifying the "type=" option for -netdev can be turned into a switch. Format validation with qemu_opts_validate() can be removed because the visitor covers it. Relatedly, the "net_client_types" array is reduced to an array of init functions that can be directly indexed by opts->kind. (Help text is available in the schema JSON.) The outermost negation in the condition around qemu_find_vlan() was flattened, because it expresses the dependent code's requirements more clearly. VLAN lookup is avoided if there's no init function to pass the VLAN to. Whenever the value of type=... is needed, we substitute NetClientOptionsKind_lookup[kind]. The individual init functions are not converted yet, thus the original QemuOpts instance is passed transparently. v1->v2: - NetLegacy::name is optional. Tracked it through all init functions: they all handle a NULL name. Updated commit message accordingly. v2->v3: - NetLegacy::id is allowed and takes precedence over NetLegacy::name.

This was done with: sed -i 's/qemu_get_clock\>/qemu_get_clock_ns/' \ $(git grep -l 'qemu_get_clock\>' ) sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \ $(git grep -l 'qemu_new_timer\>' ) after checking that get_clock and new_timer never occur twice on the same line. There were no missed occurrences; however, even if there had been, they would have been caught by the compiler. There was exactly one false positive in qemu_run_timers: - current_time = qemu_get_clock (clock); + current_time = qemu_get_clock_ns (clock); which is of course not in this patch.

There's one place that passes arguments without newlines intentionally: load_vmstate(). Fix it up.
