Current isa-l has possibility to return corrupted decoded data or corrupted reconstructed data on decode/reconstruct without error code. That is from the specification of isa-l rs vandermond matrix discussed at [1]. With many # of parities cases, we may hit the case above due to failing to get the inverse matrix from the encode matrix. The isa-l maintener gbtucker suggests a good way to detect the failing inverse matrix, that we should handle the return value gf_invert_matrix. If gf_invert_matrix returns not 0, we should stop to decode/reconstruct and return failure return code to the caller immediately. Otherwise, the caller regards the garbage data/fragment as correct one. And this patch adds the specific test case we can hit the issue (it happens not so general). 1: https://github.com/01org/isa-l/issues/10 Related-Change: I6eb150d9d0c3febf233570fa7729f9f72df2e9be Change-Id: Icee788a0931fe692fe0de31fabc4ba450e338a87 |
