Thanks Jakub this looks correct to me. I can't remember at the moment
or dig up in the email or git why it was originally moved into the
update logic. Maybe Cong can comment seeing it was his original patch?
I seemed to have missed the error path on original review :(
From my side though,

Cover the scenario when we cannot insert a socket into the sockmap, because
it has it is using ULP. Failed insert should not have any effect on the ULP
state. This is a regression test.

Ah, thanks. Sent v2. I hope we can borrow a trick from systemd's book
and adapt __attribute__((cleanup(f))) in the future.

Cover the scenario when we cannot insert a socket into the sockmap, because
it has it is using ULP. Failed insert should not have any effect on the ULP
