            Bug ID: 30151
           Summary: sgetsgent_r does not implement ERANGE protocol
                    compatible with sgetsgent
           Product: glibc
           Version: 2.38
            Status: NEW
          Severity: normal
          Priority: P2
         Component: nss
          Assignee: unassigned at sourceware dot org
          Reporter: fweimer at redhat dot com
  Target Milestone: ---

The sgetsgent function checks errno for ERANGE, but sgetsgent_r only returns
ERANGE, but does not set errno to ERANGE. As a result, sgetsgent does not
detect failure at all, and returns indicating success without filling in the
struct sgrp result.

This bug is somewhat similar in effect as bug 20338, but the root cause is
quite different.
