Subject: [PATCH 04/20] openlap reentrant gethostby
|
|
|
|
The non-reentrant gethostbyXXXX() functions deadlock if called recursively, for
|
|
example if libldap needs to be initialized from within gethostbyXXXX() (which
|
|
actually happens if nss_ldap is used for hostname resolution and earlier
|
|
modules can't resolve the local host name), so use the reentrant versions of
|
|
the functions, even if we're not being compiled for use in libldap_r
|
|
|
|
