libtirpc is the replacement. I wasn't aware if uses libc-provided rpc headers (presumably only if they exist, since folks are using it fine on musl) but even if so I think the types will automatically update when time_t changes. Of course that leaves the libtirpc ABI dependent on which time_t is used.
Ok, makes sense. I suppose it just provides a header with the same name then.
- nfs-utils build-depends on libtirpc-dev, and isn't using the glibc
SunRPC headers except for <rpc/netdb.h>. libtirpc's <rpc/rpcent.h> specifically avoids declaring things that are also declared in glibc's <rpc/netdb.h>.
ntirpc is a different port of the SunRPC code, used by nfs-ganesha.
nis and nfswatch really are using the glibc SunRPC headers.
Which part of NIS? There's a new upstream for libnsl https://github.com/thkukuk/libnsl and the NSS module https://github.com/thkukuk/libnss_nis. (There is a nisplus module as well.)
All these use libtirpc and support IPv6 in addition to IPv4. As far as I know, it is possible to build a full NIS stack without relying on any of the legacy glibc code.
(I don't know about nfswatch.)
