Return failure in getnetgrent only when all netgroups have been searched (#17363)
The netgroups lookup code fails when one of the groups in the search tree is empty. In such a case it only returns the leaves of the tree after the blank netgroup. This is because the line parser returns a NOTFOUND status when the netgroup exists but is empty. The __getnetgrent_internal implementation needs to be fixed to try remaining groups if the current group is entry. This patch implements this fix. Tested on x86_64. [BZ #17363] * inet/getnetgrent_r.c (__internal_getnetgrent_r): Try next group if the current group is empty.
