There was a problem hiding this comment.
if errors.Is(err, unix.ENODATA) would be better.

No, it's because we haven't bumped the Go version for linting recently. I'll fix it now. |

@rchincha Can you rebase this? CI has been fixed. |

generatelayer closes the tarwriter, but generateinsertlayer forgets to. Closing the tarwriter writes the required footer of 1k of zeros. This results in tar files that are complete but invalid, and different reading tools will behave differently: - bsdtar doesn't complain and exits 0 - gnu tar (and security scanning tools that use it) will exit 2 with an unexpected EOF message - python's tarfile library will raise an Unexpected EOF error - golang's archive/tar library can raise an unexpected EOF error, but for some files created by generateinsertlayer, it just raises a plain EOF error, which means golang based tools generally ignore this and work fine, this includes umoci.

This warning is a little confusing when err is nil, and doesn't add any info in that case. Let's clean that up. Signed-off-by: Michael McCracken <[email protected]> (cherry picked from commit 653952b)
add a check to image-verify to ensure that all generated tar blobs are valid and do not cause gnu tar to exit nonzero add an insert test that adds a very small file to trigger unexpected EOF in the case where GenerateInsertLayer forgets to close the TarWriter.

Current behavior determines if a path is a whiteout if a overlay char dev is present. Additionally, also check the extended attrs. Signed-off-by: Ramkumar Chinchani <[email protected]>
fix: handle overlay xattr opaque bit
CI failures indicate that this could be another error code that needs to be handled. Signed-off-by: Ramkumar Chinchani <[email protected]>

When the underlying filesystem is overlayfs, it is possible that xattrs are present but without the data. So check for this case specifically and ignore it.
