  o Minor bugfixes (scheduler, KIST):
    - Avoid a possible integer overflow when computing the available space on
      the TCP buffer of a channel. This has no security implications but can
      make KIST not behave properly by allowing more cells on a already
      saturated connection. Fixes bug 24590; bugfix on 0.3.2.1-alpha.
sched: Avoid integer overflow when computing tcp_space In KIST, we could have a small congestion window value than the unacked packets leading to a integer overflow which leaves the tcp_space value to be humongous. This has no security implications but it results in KIST scheduler allowing to send cells on a potentially saturated connection. Found by #24423. Fixes #24590.
