Remove the /exists///// behaviour from here. The /nonexistant behaviour remains in the kernel and needs to be shot next. There may be ports fallout, but we doubt it. ok beck djm Remove old realpath(3), and the userland-vs-kernel realpath verification 2019-06-17T03:13:17Z deraadt deraadt@openbsd.org 2019-06-17T03:13:17Z urn:sha1:390a7db7ecbbeb7b2bffd2c64e59abb248fb9b6c code. We now user the simple userland wrapper on top of __realpath(2). The non-POSIX behaviour still remains, that is the next component to fix. From a diff by beck, but I managed to chainsaw it a bit further. Tested in snaps for a couple of days. ok beck __realpath(2) appears to have improved, so re-enable the code that 2019-05-30T13:22:48Z deraadt deraadt@openbsd.org 2019-05-30T13:22:48Z urn:sha1:1f4d754ac3a00771ac9f032473f2dd8437bb8cb4 checks userland-parsing vs kernel parsing, we are hoping to spot another bug..

Once we have run with that for a little while we will remove the old code ok deraadt@ Fix one possible buffer overflow and one underflow.
