This patch addresses the fuse privileged mounted filesystems in environments which are unwilling to accept the risk of trusting the signature verification and want to always fail safe, but are for example using a pre-built kernel. This patch defines a new builtin policy "unverifiable_sigs", which canHow about recalc_unverifiable_sigs?Cute, I really like that name, but in this case we're failing the signature verification.quoted
It's long, but unverifiable_sigs is not clear about whether the intent is to accept or recalculate them. (or fail_unverifiable_sigs like the flag)Could we abbreviate it to "fail_usigs"? ?Or perhaps allow both "fail_unverifiable_sigs" and "fail_usigs".That sounds good. Or fail_unverified? But so long as 'fail' is somehow clearly implied by the name.
None of these names mean anything to anyone but us. ?How about "fail_safe"? ?That at least has some meaning to some people.
