We have a check for symlinks and hardlinks so that we refuse to open
ccaches through symlinks or which have hardlinks. This check is too
strict, checking for `st_nlink != 1`, which runs into trouble when a
ccache is mounted as a file into a container, in which case `stat(2)`
reports it as having zero links.
The fix is to check for `st_nlink > 1`:
- if (sb2.st_nlink != 1) {
+ if (sb2.st_nlink > 1) {
krb5_set_error_message(context, EPERM, N_("Refuses to open hardlinks for caches FILE:%s", ""), filename);
Though I question the utility of the hardlink check. MIT Kerberos
doesn't have it.
