Description Florian Weimer 2019-06-21 12:34:39 UTC
+++ This bug was initially created as a clone of Bug #1710894 +++

We should backport this patch in preparation of a potential future fix for bug 132608 later in the life-cycle of Red Hat Enterprise Linux 8.

    nss: Turn __nss_database_lookup into a compatibility symbol
    
    The function uses the internal service_user type, so it is not
    really usable from the outside of glibc.  Rename the function
    to __nss_database_lookup2 for internal use, and change
    __nss_database_lookup to always indicate failure to the caller.
    
    __nss_next already was a compatibility symbol.  The new
    implementation always fails and no longer calls __nss_next2.
    
    unscd, the alternative nscd implementation, does not use
    __nss_database_lookup, so it is not affected by this change.
