off-by-one check in papr_scm_meta_{get, set} # # A validation check to prevent out of bounds read/write inside # functions papr_scm_meta_{get,set}() is off-by-one that prevent reads # and writes to the last byte of the label area. # # This bug manifests as a failure to probe a dimm when libnvdimm is # unable to read the entire config-area as advertised by # ND_CMD_GET_CONFIG_SIZE. This usually happens when there are large # number of namespaces created in the region backed by the dimm and the # label-index spans max possible config-area. An error of the form below # usually reported in the kernel logs: # # [ 255.293912] nvdimm: probe of nmem0 failed with error -22 # # The patch fixes these validation checks there by letting libnvdimm # access the entire config-area. # # Fixes: 53e80bd042773('powerpc/nvdimm: Add support for multibyte read/write for metadata') # Signed-off-by: Vaibhav Jain <vaibhav@linux.ibm.com> # Reviewed-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> #
