Update.
1998-06-01 Thorsten Kukuk <kukuk@vt.uni-paderborn.de> * nis/nis_call.c: Make directory search faster. * nis/nis_callback.c: Insert public key of user in callback data. * nis/nis_clone_obj.c: Make size from type u_long, not u_int. * nis/nis_creategroup.c: Check for NULL pointer, fill in more fields. * nis/nis_findserv.c: Rename __pmap_getport to __pmap_getnisport. * nis/nis_intern.h: Remove duplicated prototype. 1998-06-01 Thorsten Kukuk <kukuk@vt.uni-paderborn.de> * sunrpc/auth_des.c: Move prototypes from here ... * sunrpc/rpc/auth.h: ... to here. * sunrpc/clnt_tcp.c: Add more control flags. * sunrpc/clnt_udp.c: Likewise. * sunrpc/netname.c (host2netname): Remove prefixing dot from domainname. * sunrpc/rpc/clnt.h: Document, which control flags are not implementable. * sunrpc/svcauth_des.c: Use key_decryptsession_pk to avoid deadlock.
