Modified files:
lib/libc/yp : yp_bind.c
lib/libc/rpc : Makefile.inc clnt_udp.c
Added files:
lib/libc/rpc : clnt_udp.h clnt_udp_bufcreate.c
Log message:
When getpwnam(3) reaches out to YP, it calls clntudp_create(3) with a
pre-initialized ypconnect(2) socket. That calls clntudp_bufcreate(),
which contains code checking if the socket and address are configured..
If not, socket(2) is called, or an address allocation is performed via
the portmapper (which calls a whole lot more code).
Split clnt_udp.c into two .c files (which will compile as seperate .o
files), and create a new libc-private clntudp_bufcreate_simple() function
which skips the socket and address work.
Result: In most static binaries, this reduces the text segment by
~100K, and removes 5-7 system call stubs -- which might matter for
non-pledged binaries with otherwise lack socket(2).
