Hi Steve,
tirpc_rpcb_rmtcall is failing. I was able to reproduce it on
* openSUSE Tumbleweed with libtirpc 1.3.3
* Debian stable 11 (bullseye) with libtirpc 1.3.1-1
OTOH SLE 15-SP4 with libtirpc 1.2.6 is working.

The problem is in tirpc_rpcb_rmtcall.c [1], which calls rpcb_rmtcall(), which
returns 1 (I suppose RPC_CANTENCODEARGS - can't encode arguments - enum
clnt_stat from tirpc/rpc/clnt_stat.h):
cs = rpcb_rmtcall(nconf, argc[1], progNum, VERSNUM, PROCNUM,
(xdrproc_t) xdr_int, (char *)&var_snd,
(xdrproc_t) xdr_int, (char *)&var_rec, tv, &svcaddr);
test_status = (cs == RPC_SUCCESS) ? 0 : 1;
//This last printf gives the result status to the tests suite
//normally should be 0: test has passed or 1: test has failed
printf("%d\n", test_status);
return test_status;
Any idea what could be wrong with these very old tests?
Kind regards,
Petr

No... No idea... but I'm unable to reproduce it. It appears
you are using different repo that the one I found on
github [1]. But...
Looking code, RPC_CANTENCODEARGS is returned when
there is an xdr problem which might means a
memory problem??
With that said... commits 21718bbb^..fa153d63 did
make a lot of changes in the locking and cache
management.

Thanks a lot for looking into the issue.
BTW on which Fedora/RHEL/CentOS version did you test?
No, I'm also using the official LTP repository on github [1].
And I compile on recent glibc (> 2.32, which removed SUN-RPC) and with libtirpc:
./configure
...
libtirpc: yes
glibc SUN-RPC: no

That was released on 1.3.3, but I'm able to reproduce it on
Debian stable 11 (bullseye) with libtirpc 1.3.1-1.
