Looks like a bug. I have a potential fix, can you try it? You will need to apply auth-dummy-ganesha.patch to Ganesha, and auth-dummy-ntirpc.patch to ntirpc. You will likely have to re-run cmake to get ntirpc to regenerate it's exports.
thank you for the patches. They solve the segfault in nfs_rpc_create_chan_v40(), but later another one occurs in clnt_vc_call(): Thread 15 "ganesha.nfsd" received signal SIGSEGV, Segmentation fault. 0x00007ffff617ba52 in clnt_vc_call (cc=0x7fffee5b2300) at /root/src/patch/libntirpc-1.6.2/src/clnt_vc.c:301 301 (cc->cc_auth->ah_cred.oa_flavor == RPCSEC_GSS) (gdb) print cc->cc_auth $8 = (AUTH *) 0x0 (gdb) bt #0 0x00007ffff617ba52 in clnt_vc_call (cc=0x7fffee5b2300) at /root/src/patch/libntirpc-1.6.2/src/clnt_vc.c:301 #1 0x00007ffff61793d3 in clnt_req_wait_reply (cc=0x7fffee5b2300) at /root/src/patch/libntirpc-1.6.2/src/clnt_generic.c:609 #2 0x00005555555a49e0 in rpc_cb_null (chan=0x7fffee5321b0, locked=false) at /root/src/patch/nfs-ganesha-2.6.2/src/MainNFSD/nfs_rpc_callback.c:672 #3 0x00005555555a6976 in nfs_test_cb_chan (clientid=0x7fffee532100) at /root/src/patch/nfs-ganesha-2.6.2/src/MainNFSD/nfs_rpc_callback.c:1326 #4 0x00005555555ec557 in nfs4_op_setclientid_confirm (op=0x7fffee550020, data=0x7fffee1fba70, resp=0x7fffee5500c0) at /root/src/patch/nfs-ganesha-2.6.2/src/Protocols/NFS/nfs4_op_setclientid_confirm.c:455 #5 0x00005555555c6672 in nfs4_Compound (arg=0x7ffff13c6f08, req=0x7ffff13c6800, res=0x7fffee552280) at /root/src/patch/nfs-ganesha-2.6.2/src/Protocols/NFS/nfs4_Compound.c:752 #6 0x00005555555c316d in nfs_rpc_process_request (reqdata=0x7ffff13c6800) at /root/src/patch/nfs-ganesha-2.6.2/src/MainNFSD/nfs_worker_thread.c:1329 #7 0x00005555555c3956 in nfs_rpc_valid_NFS (req=0x7ffff13c6800) at /root/src/patch/nfs-ganesha-2.6.2/src/MainNFSD/nfs_worker_thread.c:1554 #8 0x00007ffff6195506 in svc_vc_decode (req=0x7ffff13c6800) at /root/src/patch/libntirpc-1.6.2/src/svc_vc.c:815 #9 0x00005555555b6214 in nfs_rpc_decode_request (xprt=0x7ffff401b400, xdrs=0x7ffff404e980) ---Type <return> to continue, or q <return> to quit---q Due to the authentication failure chan->auth is set to NULL in nfs_rpc_create_chan_v40().
