Subject: [PATCH] security: don't fail if built without attr support
|
|
|
|
If built without attr support removing any image will trigger
|
|
qemuBlockRemoveImageMetadata (the one that emits the warning)
|
|
-> qemuSecurityMoveImageMetadata
|
|
-> virSecurityManagerMoveImageMetadata
|
|
-> virSecurityDACMoveImageMetadata
|
|
-> virSecurityDACMoveImageMetadataHelper
|
|
-> virProcessRunInFork (spawns subprocess)
|
|
-> virSecurityMoveRememberedLabel
|
|
|
|
In there due to !HAVE_LIBATTR virFileGetXAttrQuiet will return
|
|
ENOSYS and from there the chain will error out.
|
|
|
|
That is wrong and looks like:
|
|
libvirtd[6320]: internal error: child reported (status=125):
|
|
libvirtd[6320]: Unable to remove disk metadata on vm testguest from
|
|
/var/lib/uvtool/libvirt/images/testguest.qcow (disk target vda)
|
|
|
|
This change makes virSecurityDACMoveImageMetadataHelper and
|
|
virSecuritySELinuxMoveImageMetadataHelper accept that
|
|
error code gracefully and in that sense it is an extension of:
|
|
5214b2f1a3f "security: Don't skip label restore on file systems lacking XATTRs"
|
|
which does the same for other call chains into the virFile*XAttr functions.
|
|
|
|
