I should have asked, what FSAL is providing the xattrs? Matt On Tue, Mar 16, 2021 at 7:46 AM Daniel Gryniewicz <dang@redhat.com> wrote:
Like all ALL_CAPS() calls in ntirpc, AUTH_WRAP() is a call through a function pointer, in this case the wrap() call for the auth_none set. All it does is call the higher level's encode function, in this case xdr_COMPOUND4res_extended(). So there was an XDR encoding failure. Something must be wrong with the results array, would be my guess? Unfortunately, XDR encoding has no debug output, and only returns a bool, so there's no hints as to what failed to encode.

I recently submitted some patches to clean up the xattr handling support for v4.2+, and discovered that there are xattr tests in pynfs!
I tested against them and XATT8 failed, with the server timing out on the reply. Here's an excerpt from NIV_FULL_DEBUG run (sans some too- chatty debug messages that I disabled in the dbus code):

It looks like it all works, until we hit the SVCAUTH_WRAP failure...which is odd because this run is using AUTH_SYS, so you'd think that would be a no-op?
In any case, I could use some help deciphering this log. What happened?
TIA!
