PROTON-712: check getprotobyname for NULL return value (patch from Sahir Hoda)
> Seg fault due to missing NULL return value check of getprotobyname
> ------------------------------------------------------------------
>
> Key: PROTON-712
> URL: https://issues.apache.org/jira/browse/PROTON-712
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: 0.7
> Reporter: Sahir Hoda
> Assignee: Rafael H. Schloming
> Labels: easyfix, patch
> Attachments: getprotobyname-err-check.patch
>
>
> There are several places proton-c makes calls to getprotobyname and
> dereferences the return value without checking for NULL first. Documentation
> for getprotobyname indicates it can return NULL if there was an error. We
> have seen seg faults in testing where getprotobyname returned NULL.
> Attached is a patch that adds some simple error checking to the
> getprotobyname call.
