[Bug 925364] Re: rpc.gssd exits immediately

[David Ambrose-Griffith]

I've run debsums, and nothing comes to light there.

I've also downloaded the bzr branch and compiled a new copy, which
exhibits the same symptoms.

Adding in some debugging lines, there seems to be something odd going on
around line 216 on gssd_main_loop.c where it tests for something and
exits with status code 1 if it is true

Changing that to..

        printerr(1, "beginning poll\n");
        while (1) {
                while (dir_changed) {
                        dir_changed = 0;
                        if (update_client_list()) {
                                /* Error msg is already printed */
                                printerr(1, "DAG Test exit\n");
                                exit(1);
                        }


causes DAG Test exit to be printed.


Looking back at the update_client_list() routine around line 588 in gssd_proc.c and adding in a debug line like so

/* Used to read (and re-read) list of clients, set up poll array. */
int
update_client_list(void)
{
        int retval = -1;
        struct topdirs_info *tdi;

        TAILQ_FOREACH(tdi, &topdirs_list, list) {
                retval = process_pipedir(tdi->dirname);
                if (retval)
                        printerr(1, "WARNING: error processing %s\n",
                                 tdi->dirname);

        }
        printerr(1, "DAG WARNING: retval=%d\n", retval);
        return retval;
}

root at cisadl-tst:~/nfs-utils/utils/gssd# ./gssd -fvvv
beginning poll
DAG WARNING: retval=-1
DAG Test exit


Any further ideas?

Title:
  rpc.gssd exits immediately

Status in “nfs-utils” package in Ubuntu:
  Incomplete

Bug description:
  Release: Precise Pangolin 12.04 Alpha
  Version:  1.2.5-3ubuntu1 (nfs-common)

  Starting rpc.gssd initially appears to launch ok

  root at cisadl-tst:~# status gssd
  gssd stop/waiting
  root at cisadl-tst:~# start gssd
  gssd start/pre-start, process 3624
  root at cisadl-tst:~# status gssd
  gssd stop/waiting
  root at cisadl-tst:~# 

  
  Running rpc.gssd in the foreground manually also seems to exit immediately with status code 1

  root at cisadl-tst:~# rpc.gssd -fvvv ; echo $?
  beginning poll
  1

  Expected behaviour:   rpc.gssd starts and allows Kerberized NFS to work
  Observed behaviour:   rpc.gssd exits immediately and Kerberized NFS fails.

  I have attached the output of strace -f against rpc.gssd if it is of
  any help.
