The results of ecumenical councils, universal and ordinary tradition when recognized as such and the ex-cathedra statements of the Pope.
Okay, so more than just ex-cathedra teachings are considered infallible?
AmericanCatholic.org said not all ecumenical council results are infallible. But there seems to be disagreement among Catholics about exactly what is.
No. The male priesthood is dogma. It was declared infallible.
Okay.
Could you give an example? Sometimes people misunderstands things like priestly celibacy(see below), which is a discipline and not a doctrine, or limbo, which was never a doctrine of the Church just a widely held belief.
I may be misunderstanding like you suggested. I don't know the differences between declarations, doctrines, catechisms, etc. But I'm just curious about the issue of infallibility. So here's an example:
According to various websites, popes have variously defended, endorsed, participated in, made into canon law, condemned, forbidden, and decried slavery.
From: Is Cannon Law guaranteed to be infallible? - Catholic Answers Forums
"Canon law is concerned with discipline. Infallibility has to do with faith and morals. So of it self, canon law is not infallible. However, insofar as canon law deals with matters that the Church considers infallible, then such content is infallible. Whether the content of canon law is infallible or not, Catholics are obliged to obey it because it is an expression of the authority the Church has received from Christ, Himself."
Whether considered doctrine or discipline, it seems very clear there were several times throughout history that slavery was strongly endorsed papally. Today it is strongly condemned. Polar opposite church teachings.
