Description Björn Jacke 2021-05-08 01:14:40 UTC
the file/directory ownership is not available if a file/directory is not readable. The ownership should be readable in any case though.

I ran into this problem during some ACL testing: it *must* be possible to grant new permissions on a file/directory after you removed all permissions before - *if* you are the owner.

Is this a 4.14 regression? Does it work in 4.13?

neither in 4.12/4.13. You can just check with a simple "touch file; chmod 000 file" and look at it in explorer.

(For the "revover from 0 ACEs" test there might be more issues but this is the first obvious one.)

Ok, thanks for confirming. This can now be fixed in 4.14 thanks for pathref fsps.
