This was the patch where I had a question on ACL semantics:
+ * @generate: both
+ * @acl: domain:snapshot
+ * @acl: domain:fs_freeze:VIR_DOMAIN_SNAPSHOT_CREATE_QUIESCE
+ */
+ REMOTE_PROC_DOMAIN_SNAPSHOT_CREATE_XML2 = 418
Is there an easy way to make this also do a check against @acl:
domain:checkpoint, but only when the checkpointXml flag is non-NULL? The
quickest I could think of would be automatically setting a
VIR_DOMAIN_SNAPSHOT_CREATE_CHECKPOINT flag that
libvirt-domain-snapshot.c automatically sets if checkpointXml is clear,
so that I could then write @acl:
domain:checkpoint:VIR_DOMAIN_SNAPSHOT_CREATE_CHECKPOINT. We've set
witness flags in other situations (such as VIR_TYPED_PARAM_STRING_OKAY),
but never for the purpose of an ACL check. On the other hand, tweaking
the ACL code generator to take more than just 'flags' for doing checks
seems like a lot of work for very little gain.
