Fixes a number of issues. From the changelog: - Avoid getting stuck in a loop writing huge key files, reported by Bruno Thomsen - Avoid crash on exit due to cleaned up keys before last packets are sent, debugged by Ronald Wahl - Fix a race condition in rekeying where Dropbear would exit if it received a still-in-flight packet after initiating rekeying. Reported by Oliver Metz. This is a longstanding bug but is triggered more easily since 2013.57 - Ensure that generated RSA keys are always exactly the length requested. Previously Dropbear always generated N+16 or N+15 bit keys. Thanks to Unit 193 - Fix DROPBEAR_CLI_IMMEDIATE_AUTH mode which saves a network round trip if the first public key succeeds. Still not enabled by default, needs more compatibility testing with other implementations. - Fix signal handlers so that errno is saved, thanks to Erik Ahlén for a patch and Mark Wickham for independently spotting the same problem. And at the same time get rid of the TIMEVAL_TO_TIMESPEC as dropbear provides a fallback implementation if not available (and has done so since 2006).
