One of the tests in GLib's test suite is gdbus-server-auth, which tests
the GDBusServer IPC server, among other things verifying that a libdbus
client can interoperate with the GDBusServer.

It appears this test consistently fails on arm-conova-03 (with either
its armel or armhf hat), but not on other buildds (!), when it exercises
a TCP connection with the DBUS_COOKIE_SHA1 authentication mechanism. I
don't know why. It might be something timing-related (the test was intended
to reproduce a timing problem in DBUS_COOKIE_SHA1 where GDBus and libdbus
failed to interoperate).

I've tried running the same test in a loop on porterboxes in the past,
without being able to reproduce the problem in 2000 consecutive runs.

What hardware is arm-conova-03 running on? Is it the same as amdahl, which
has a similar description on db.debian.org?

Is there anything odd about how arm-conova-03's filesystem or /tmp works,
perhaps using tmpfs or NFS where other buildds don't, or not using tmpfs
where other buildds do, or an unusual level of load?

Or is there anything odd about arm-conova-03's TCP or other networking
setup?

Is there anything else special about arm-conova-03 that would make it have
unusual timing more often, perhaps pausing execution for a significant
time and then resuming?

If I upload a version to experimental with extra debug logging, is it
possible for porters or buildd admins to force it to be scheduled on
arm-conova-03 or a similar machine?

Thanks,

For whatever reason (possibly a behaviour change in glibc?), this seems
to be working now. I can run

    bwrap --dev-bind / / --unshare-net meson test -C ~/tmp/build/glib/debug

and I can see libdbus clients successfully connecting to a GDBus server
with IPv4 even in that restricted environment:

# Testing GDBus server at tcp:host=127.0.0.1 / libdbus client, with flags: 
external:false anonymous:false sha1:true abstract:false tcp:true
...
# GLib-GIO-DEBUG: Rejecting "ANONYMOUS" authentication: not DBUS_COOKIE_SHA1
# GLib-GIO-DEBUG: Accepting DBUS_COOKIE_SHA1 authentication
# GLib-GIO-DEBUG: Rejecting "EXTERNAL" authentication: not DBUS_COOKIE_SHA1
# GLib-GIO-DEBUG: Authorizing peer with credentials: 
GCredentials:linux-ucred:pid=0
# GLib-GIO-DEBUG: New connection from peer with credentials: 
GCredentials:linux-ucred:pid=0
# GLib-GIO-DEBUG: Server says libdbus client 0 is uid 4294967295, pid -1

Also, even if this test did fail, it is no longer RC for Debian, because we
have marked the TCP/DBUS_COOKIE_SHA1 parts of gdbus-server-auth test as flaky
(they intermittently fail on some buildds, but we cannot reproduce the
failure in a development environment, and D-Bus over TCP is strongly
discouraged anyway).

I'm closing this as having been resolved in the first version where the
TCP parts of gdbus-server-auth were marked as flaky.
