Oh, wait. That's not an empty list, it's an uninitialized list. Something is trying to log before init_logging() has been called, which, of course, won't work. That's called *super* early in startup (right after command line arguments are parsed), so it should be easy to avoid logging that early. Daniel On 7/24/20 11:16 AM, Becker, Jeffrey C. (ARC-TN)[InuTeq, LLC] wrote:

I noticed that 1) this takes place very early in the starting of ganesha.nfsd, and 2) there's nothing in the log file yet, so perhaps logging hasn't been set up yet?

So, that shouldn't cause a crash. glist_for_each() is valid on an empty list, and it will never enter the loop, so it should just skip the entire block.

That said, your config looked like it had a valid facility, so there should be an entry in that list.

I added a site-local feature to Ganesha that is enabled by a command line option. It's one of my functions that's trying to log. On 7/24/20, 8:51 AM, "Becker, Jeffrey C.

On 7/24/20, 8:48 AM, "Daniel Gryniewicz" <dang@redhat.com> wrote: Oh, wait. That's not an empty list, it's an uninitialized list. Something is trying to log before init_logging() has been called, which, of course, won't work. That's called *super* early in startup (right after command line arguments are parsed), so it should be easy to avoid logging that early. Daniel On 7/24/20 11:16 AM, Becker, Jeffrey C.
