2020-09-24Change segment/pending queue to use receive buffer limits.Bhasker Hariharan
segment_queue today has its own standalone limit of MaxUnprocessedSegments but this can be a problem in UnlockUser() we do not release the lock till there are segments to be processed. What can happen is as handleSegments dequeues packets more keep getting queued and we will never release the lock. This can keep happening even if the receive buffer is full because nothing can read() till we release the lock. Further having a separate limit for pending segments makes it harder to track memory usage etc. Unifying the limits makes it easier to reason about memory in use and makes the overall buffer behaviour more consistent.

2020-09-23fuse: don't call dentry.InsertChildAndrei Vagin
It is called from the kernfs code (OpenAt and revalidateChildLocked()). For RemoveChildLocked, it is opposed. We need to call it from fuse.RmDir and fuse.Unlink. PiperOrigin-RevId: 333453218

2020-09-22pkg/buffer: Reorganize internal structure to allow dynamic sizes.Ting-Yu Wang
This change changes `buffer.data` into a `[]byte`, from `[bufferSize]byte`. In exchange, each `buffer` is now grouped together to reduce the number of allocation. Plus, `View` now holds an embeded list of `buffer` (via `pool`) to support the happy path which the number of buffer is small. Expect no extra allocation for the happy path. It is to enable the use case for PacketBuffer, which * each `View` is small (way less than `defaultBufferSize`), and * needs to dynamically transfer ownership of `[]byte` to `View`. (to allow gradual migration) PiperOrigin-RevId: 333197252
