nscd: Do not use __inet_aton_exact@GLIBC_PRIVATE [BZ #20018] |
|
|
|
This commit avoids referencing the __inet_aton_exact@GLIBC_PRIVATE |
|
symbol from nscd. In master, the separately-compiled getaddrinfo |
|
implementation in nscd needs it, however such an internal ABI change |
|
is not desirable on a release branch if it can be avoided. |
|
|
|
(Note: This commit was backported from the release/2.28/master branch.) |
