Patches 1 and 2 should be pushed for 8.0 as the bug was introduced in
this dev cycle and the patches are specifically kept very simple.
The rest of the series refactors the snapshot validation and helper code
to have less weird semantics which lead to this bug.
Peter Krempa (17):
qemuSnapshotRedefine: Rename 'def' to 'snapdef'
qemuSnapshotRedefine: Fix use of snapshot definition after free
virDomainMomentAssignDef: Simplify error handling
virDomainSnapshotRedefineValidate: Fix validation of
VIR_DOMAIN_SNAPSHOT_CREATE_DISK_ONLY flag
virDomainSnapshotAlignDisks: Improve function comment
virDomainSnapshotAlignDisks: Convert @default_snapshot to
virDomainSnapshotLocation
virDomainSnapshotAlignDisks: Move 'require_match' selection logic
inside
virDomainSnapshotAlignDisks: Allow alternate domain definition when
redefining
virDomainSnapshotRedefineValidate: Unexport
virDomainSnapshotRedefinePrep: Use 'snapdef' for snapshot definition
object
virDomainSnapshotRedefineValidate: Don't modify the snapshot
definition
testDomainSnapshotCreateXML: Extract snapshot redefinition code
qemuSnapshotCreate: Use 'snapdef' instead of 'def'
qemuSnapshotCreate: Standardize handling of the reference on @snapdef
qemuDomainSnapshotLoad: Refactor handling of snapshot definition
object
