Subject: [PATCH] qapi-types.py: Fix enum struct sizes on i686
|
|
|
|
Unlike other list types, enum wasn't adding any padding, which caused
|
|
a mismatch between the generated struct size and GenericList struct
|
|
size. More details in a678e26cbe89f7a27cbce794c2c2784571ee9d21
|
|
|
|
This crashed qemu if calling qmp query-tpm-types for example, which
|
|
upsets libvirt capabilities probing. Reproducer on i686:
|
|
|
|
(sleep 5; printf '{"execute":"qmp_capabilities"}\n{"execute":"query-tpm-types"}\n') | ./i386-softmmu/qemu-system-i386 -S -nodefaults -nographic -M none -qmp stdio
