TODO List

Driver

Implement ECN support via the IP_ECN cmsg

Rework IOCTL to accept requests over 4gigs

  • The current ULONG is too small
  • We should switch to using METHOD_NEITHER
  • One param is a pointer to a ULONG64 length, the other the actual buffer

Rearrange and regroup WG_DEVICE

  • Most commonly used members should be at the top
  • Members used together should be next to each other
  • Holes should be minimized
  • Don't stretch cachelines

SAL Annotations

  • Figure out __rcu best practice with SAL
  • For the MuAcquireReleaseSharedExclusive functions, make SAL detect lock imbalance. e.g. a AcquireExclusive followed by a ReleaseShared.

Bugs with no solution

Forwarding/WeakHostSend breaks IP_PKTINFO

When forwarding or weakhostsend are enabled -- which can happen via Hotspot mode -- the routing logic ignores IP_PKTINFO. This seems like a bug, but one unlikely to be fixed. We'll need a opt-in setsockopt to make IP_PKTINFO choose the right behavior in this case.

Bug workarounds

Remove IP_OPTIONS/IPV6_RTHDR hack

Currently we tag on an empty options cmsg to work around a bug in recent Windows builds, where IP_PKTINFO gets stripped if it's passed alone.
