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?
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...
Thanks a lot for looking into the issue.
BTW on which Fedora/RHEL/CentOS version did you test?
Fedora 38... but I will keep trying...
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
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
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.
Good to know... thanks!
