2015-11-05vnc: recycle empty vs->output bufferPeter Lieven1-0/+8
If the vs->output buffer is empty it will be dropped by the next qio_buffer_move_empty in vnc_jobs_consume_buffer anyway. So reuse the allocated buffer from this buffer in the worker thread where we otherwise would start with an empty (unallocated buffer). Signed-off-by: Peter Lieven <pl@kamp.de> Reviewed-by: Daniel P.

2015-11-03ehci: clear suspend bit on detachGerd Hoffmann1-1/+1
When a device is detached, clear the suspend bit (PORTSC_SUSPEND) in the port status register. The specs are not *that* clear what is supposed to happen in case a suspended device is unplugged. But the enable bit (PORTSC_PED) is cleared, and the specs mention setting suspend with enable being unset is undefined behavior. So clearing them both looks reasonable, and it actually fixes the reported bug. https://bugzilla.redhat.com/show_bug.cgi?id=1268879 Cc: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Reviewed-by: Hans de Goede <hdegoede@redhat.com> Message-id: 1445413462-18004-1-git-send-email-kraxel@redhat.com

2015-11-02qapi: Reserve 'u' member nameEric Blake6-1/+11
Now that we have separated union tag values from colliding with non-variant C names, by naming the union 'u', we should reserve this name for our use. Note that we want to forbid 'u' even in a struct with no variants, because it is possible for a future qemu release to extend QMP in a backwards-compatible manner while converting from a struct to a flat union. Fortunately, no existing clients were using this member name. If we ever find the need for QMP to have a member 'u', we could at that time relax things, perhaps by having c_name() munge the QMP member to 'q_u'. Note that we cannot forbid 'u' everywhere (by adding the rejection code to check_name()), because the existing QKeyCode enum already uses it; therefore we only reserve it as a struct type member name.

2015-11-02qapi: Finish converting to new qapi union layoutEric Blake1-22/+6
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. This patch is the back end for a series that converts to a saner qapi union layout. Now that all clients have been converted to use 'type' and 'obj->u.value', we can drop the temporary parallel support for 'kind' and 'obj->value'. Given a simple union qapi type: { 'union':'Foo', 'data': { 'a':'int', 'b':'bool' } } this is the overall effect, when compared to the state before this series of patches: | struct Foo { |- FooKind kind; |- union { /* union tag is @kind */ |+ FooKind type; |+ union { /* union tag is @type */ | void *data; | int64_t a; | bool b; |- }; |+ } u; | }; The testsuite still contains some examples of artificial restrictions (see flat-union-clash-type.json, for example) that are no longer technically necessary, now that there is no longer a collision between enum tag values and non-variant member names; but fixing this will be done in later patches, in part because some further changes are required to keep QAPISchema*.check() from asserting. Also, a later patch will add a reservation for the member name 'u' to avoid a collision between a user's non-variant names and our internal choice of C union name. Note, however, that we do not rename the generated enum, which is still 'FooKind'. A further patch could generate implicit enums as 'FooType', but while the generator already reserved the '*Kind' namespace (commit 4dc2e69), there are already QMP constructs with '*Type' naming, which means changing our reservation namespace would have lots of churn to C code to deal with a forced name change.

2015-11-02tpm: Convert to new qapi union layoutEric Blake2-5/+5
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 TPM-related code.
