2019-09-30Fix bugs in PickEphemeralPort for TCP.Bhasker Hariharan
Netstack always picks a random start point everytime PickEphemeralPort is called. While this is required for UDP so that DNS requests go out through a randomized set of ports it is not required for TCP. Infact Linux explicitly hashes the (srcip, dstip, dstport) and a one time secret initialized at start of the application to get a random offset. But to ensure it doesn't start from the same point on every scan it uses a static hint that is incremented by 2 in every call to pick ephemeral ports. The reason for 2 is Linux seems to split the port ranges where active connects seem to use even ones while odd ones are used by listening sockets. This CL implements a similar strategy where we use a hash + hint to generate the offset to start the search for a free Ephemeral port. This ensures that we cycle through the available port space in order for repeated connects to the same destination and significantly reduces the chance of picking a recently released port.

2018-09-04Distinguish Element and Linker for ilist.Adin Scannell
Furthermore, allow for the specification of an ElementMapper. This allows a single "Element" type to exist on multiple inline lists, and work without having to embed the entry type. This is a requisite change for supporting a per-Inode list of Dirents. PiperOrigin-RevId: 211467497 Change-Id: If2768999b43e03fdaecf8ed15f435fe37518d163

This CL also puts the congestion control logic behind an interface so that we can easily swap it out for say CUBIC in the future. PiperOrigin-RevId: 205732848 Change-Id: I891cdfd17d4d126b658b5faa0c6bd6083187944b
