We say sorry to our readers that we are unable to make a detailed commentary on this narartion.
We are just showing it from Bukhari that Hudhaifa Yamani who was a righteous and trustworthy companion of The Holy Prophet.( Shias and Sunnis both agree that The Holy Prophet told secrets about the companions to Hudhaifa Yamani).
Hudhaifa Yamani told about the afflictions, those afflictions erupted among Muslims, the narration talks about a door the door at the end it says "The subnarrator added that they deputized Masruq to ask Hudhaifa (about the door). Hudhaifa said, "The door was `Umar himself."
We can clearly understand from this narration that Hudhaifa Yamani who knew the secrets of the Holy Prophet, Hudhaifa Yamani pointed towards Umar bin Khattab that he is the door of afflictions. It simply means afflictions entered through the door.
We can imagine how much it was difficult for the great companions of The Holy Prophet to say something against Umar bin Khattab on his face.
