v2: - Patch 2: restored previous behaviour, exiting the loop immediately if the request is malformed [Jason] - Added Jason's A-b In patch 1 and 3 v1: https://lore.kernel.org/virtualization/20220621160859.196646-1-sgarzare@xxxxxxxxxx/ The first two patches essentially limit the possibility of the guest doing a DoS to the host. The third makes the simulator more correct (following what we do in vdpa_sim_net) by calling vringh_complete_iotlb() in the error path as well. Stefano Garzarella (3): vdpa_sim_blk: use dev_dbg() to print errors vdpa_sim_blk: limit the number of request handled per batch vdpa_sim_blk: call vringh_complete_iotlb() also in the error path drivers/vdpa/vdpa_sim/vdpa_sim_blk.c | 44 ++++++++++++++++++---------- 1 file changed, 29 insertions(+), 15 deletions(-) -- 2.36.1 _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
