    src/syncterm ssh.c 1.30 1.31
    Update of /cvsroot/sbbs/src/syncterm
    In directory cvs:/tmp/cvs-serv23494

    Modified Files:
    ssh.c
    Log Message:
    Fix timeout errors after a rekey. While rev 1.25 fixed large downloads,
    large uploads remained an issue as if there's no data received on the connection for over a second, the input thread would abort due to timeout.

    Fixes bug https://sf.net/p/syncterm/tickets/21/
    This is serious enough to trigger a new RC I believe (sigh)

    Also, fix an unlikely race condition. This, combined with the
    cryptlib patches, fixes various weird SSH hangs resulting from
    partial reads of the SSH packet headers... a rare event that's
    very hard to trigger. Special thanks to MeaTLoTioN for reporting
    this, and running a BBS that manages to trigger it reliably.

    Check out The Quantum Wormhole and say thanks!
