Doing this before checking OK will result in a division by zero. > + > + if (!ok) > + return; > + > + /* > + * EFimg descriptors are 9 bytes long. > + * Byte 1 of the record is the number of descriptors per record. > + */ > + if (record_length < 10) > + return; I also suggest doing something like: if ((record_length % 9) != 2 && (record_length % 9) != 1) return; to be very pedantic. > + > + if (sim->efimg == NULL) { > + sim->efimg = g_try_malloc0(num_records * 9); > + > + if (sim->efimg == NULL) > + return; > + > + sim->efimg_length = num_records * 9; > + } > + > + /* > + * TBD - if we have more than one descriptor per record, > + * pick the nicest one.
