Hi, Snaps is now carrying a change to ssh/sshd that converts their mainloops from select(2) to poll/ppoll(2). This change should be completely transparent, but please be on the lookout for any weird behaviour. Bugs in the revised mainloop are most likely to appear as crashes, hangs or ssh/sshd using lots of CPU when idle.
Please report anything you see here, to openssh@ or to me. Thanks, Damien
