2000-01-23 Philip Blundell <philb@gnu.org> Add basic support for RPC over IPv6: * sunrpc/rpc/svc.h (struct SVCXPRT): Use `struct sockaddr_storage' for remote address. (svcudp6_create, svcudp6_bufcreate, svctcp6_create): New prototypes. * sunrpc/rpc/clnt.h (clnttcp6_create, clntudp6_create, clntudp6_bufcreate): New prototypes. * inet/netinet/in.h (bindresport6): Likewise. * sunrpc/Makefile (routines): Add svc_tcp6, svc_udp6, bindrsvprt6. * sunrpc/Versions: Add svcfd6_create, svctcp6_create, svcudp6_create, svcudp6_bufcreate, svcudp6_enablecache, bindresvport6 for GLIBC_2.2. * sunrpc/rpc_main.c: Support `tcp6' and `udp6' transport types. * sunrpc/rpc_svcout.c: Likewise. * sunrpc/svc_tcp.c (rendezvous_request): Use memcpy rather than simple assignment when copying addresses. * sunrpc/svc_udp.c (cache_get): Likewise. * sunrpc/svc_unix.c (rendezvous_request): Likewise. * sunrpc/bindrsvprt6.c, sunrpc/clnt_tcp6.c, sunrpc/clnt_udp6.c, sunrpc/svc_tcp6.c, sunrpc/svc_udp6.c: New files. 2000-01-05 Philip Blundell <philb@gnu.org> * sysdeps/unix/sysv/linux/arm/mmap64.S: Correct check for ENOSYS. 2000-01-23 Andreas Jaeger <aj@suse.de> * sysdeps/unix/sysv/linux/i386/fxstat.c (__fxstat): Pass right parameter to fstat calls. 2000-01-18 Roland McGrath <roland@baalperazim.frob.com> * sysdeps/generic/bits/socket.h (__ss_aligntype, struct sockaddr_storage): Make these like Linux version, replacing old type name `__ss_align'. 2000-01-05 Roland McGrath <roland@baalperazim.frob.com> * sysdeps/generic/lseek64.c (__libc_lseek64): Renamed from __lseek64. (__lseek64, lseek64): Make these weak aliases for __libc_lseek64. * sysdeps/mach/hurd/lseek.c (__libc_lseek): Renamed from __lseek. (__lseek, lseek): Make these weak aliases for __libc_lseek. * sysdeps/mach/hurd/fcntl.c (__libc_fcntl): Renamed from __fcntl. (__fcntl, fcntl): Make these weak aliases for __libc_fcntl. * sysdeps/mach/hurd/open.c (__libc_open): Renamed from __open. (__open, open): Make these weak aliases for __libc_open. * sysdeps/generic/bits/socket.h (enum __socket_type): Remove trailing comma. (anonymous enum for MSG_*): Likewise. (anonymous enum for SO_*): Likewise. 2000-01-23 Ulrich Drepper <drepper@cygnus.com> * string/bits/string2.h: Fix typo (__GNU_SOURCE -> __USE_GNU) (PR libc/1553).
