2021-11-02Properly reap NATed connectionsGhanan Gowripalan
This change fixes a bug when reaping tuples of NAT-ed connections. Previously when reaping a tuple, the other direction's tuple ID was calculated by taking the reaping tuple's ID and inverting it. This works when a connection is not NATed but doesn't work when NAT is performed as the other direction's tuple may use different addresses. PiperOrigin-RevId: 407160930

2021-11-01Allow partial packets in ICMP errors when NATingGhanan Gowripalan
An ICMP error may not hold the full packet that triggered the ICMP response. As long as the IP header and the transport header is parsable, we should be able to successfully NAT as that is all that we need to identify the connection. PiperOrigin-RevId: 406966048

2021-10-29[syserr] Covert all linuxerr returns to error type.Zach Koopmans
Change the linuxerr.ErrorFromErrno to return an error type and not a *errors.Error type. The latter results in problems comparing to nil as <nil><nil> != <nil><*errors.Error>. In a follow up, there will be a change to remove *errors.Error.Errno(), which will also encourage users to not use Errnos to reference linuxerr. PiperOrigin-RevId: 406444419

2021-10-28Use Task blocking timer for nanosleep(2).Jamie Liu
kernel/time.Timer allocation is expensive and not sync.Poolable (since time.Timer only supports notification through a channel, requiring a goroutine to receive from the channel, and sync.Pool doesn't invoke any kind of cleanup on discarded items in the pool so it would leak timer goroutines). Using the existing Task.blockingTimer for nanosleep(), and applicable cases in clock_nanosleep(), at least avoids Timer allocation in common cases. PiperOrigin-RevId: 406248394

2021-10-27Reduce eventFD notifications on transmit.Bhasker Hariharan
When transmitting packets we only need to notify if the peer is not already processing packets. sharedData region is used to enable/disable notifications and the peer will disable notifications when its actively processing packets and enable notifications just before it goes to sleep waiting on packets. This allows more efficient transmit as the sharedmem endpoint does not need to notify on eventFD and incur an expensive host systemcall when the peer is already awake. PiperOrigin-RevId: 406018843

Connection tracking is agnostic to whether the packet is inbound or outbound. It cares who initiated the connection. The naming can get confusing as conntrack can track connections originating from any host. Part of resolving #6736. PiperOrigin-RevId: 405997540

2021-10-26platform/kvm: map vdso and vvar into a guest address spaceAndrei Vagin
Right now, each vdso call triggers vmexit. VDSO and VVAR pages are mapped with VM_IO and get_user_pages fails for such vma-s. KVM was not able to handle this case up to the v4.8 kernel. This problem was fixed by add6a0cd1c5ba ("KVM: MMU: try to fix up page faults before giving up"). For some unknown reasons, it still doesn't work in case of nested virtualization.
