Public bug reported:
Binary package hint: ecryptfs-utils
ecryptfs seems unreliable. In a recent case I performed a git fsck on a
large samba4 repo, like this:
git fsck --full --verbose --strict
it failed with a corrupt dangling commit, and dmesg showed:
[961417.528106] ecryptfs_read_and_validate_header_region: Error reading header
region; rc = [-4]
[961417.528150] Valid eCryptfs headers not found in file header region or xattr
region
[961417.528156] Either the lower file is not in a valid eCryptfs format, or the
key could not be retrieved. Plaintext passthrough mode is not enabled;
returning -EIO
I repeated the git fsck and it worked without problem, and dmesg showed
nothing.
as git fsck does not repair, we can clude that different data was read
the second time. The chance of a bad git appearing good by accident is
very small. The fact that the dmesg error shows when git fsck fails
suggests that the failure occured the first time and not the second
time.
