The protocol_name field is used when selecting a driver via protocol syntax (i.e. <protocol_name>:<filename:options:...>). Drivers that are only selected explicitly (e.g. driver=replication,mode=primary,...) should not have a protocol_name.
This patch removes the protocol_name field from the brdv_replication structure so that attempts to invoke this driver using protocol syntax will fail gracefully: $ qemu-img info replication:foo qemu-img: Could not open 'replication:': Unknown protocol 'replication' Buglink: https://bugs.launchpad.net/qemu/+bug/1726733 Signed-off-by: Fabiano Rosas <faro...@linux.vnet.ibm.com> Reviewed-by: Max Reitz <mre...@redhat.com> --- block/replication.c | 1 - replication.h | 1 - 2 files changed, 2 deletions(-) diff --git a/block/replication.c b/block/replication.c index f98ef094b9..6c0c7186d9 100644 --- a/block/replication.c +++ b/block/replication.c @@ -703,7 +703,6 @@ static void replication_stop(ReplicationState *rs, bool failover, Error **errp) BlockDriver bdrv_replication = { .format_name = "replication", - .protocol_name = "replication", .instance_size = sizeof(BDRVReplicationState), .bdrv_open = replication_open, diff --git a/replication.h b/replication.h index 8faefe005f..4c8354de23 100644 --- a/replication.h +++ b/replication.h @@ -67,7 +67,6 @@ typedef struct ReplicationState ReplicationState; * * BlockDriver bdrv_replication = { * .format_name = "replication", - * .protocol_name = "replication", * .instance_size = sizeof(BDRVReplicationState), * * .bdrv_open = replication_open, -- 2.13.6
