      websocket: limit incoming payload size · 6dba816f
      Artyom Pervukhin authored 
      Codec's Receive method calls io.ReadAll of the whole frame payload,
which can be abused by user sending large payloads in order to exhaust
server memory.

Introduce limit on received payload size defined by
Conn.MaxPayloadBytes. If payload size of the message read with
Codec.Receive exceeds limit, ErrFrameTooLarge error is returned; the
connection can still be recovered if required: the next call to Receive
would at first discard leftovers of previous oversized message before
processing the next one.

Fixes golang/go#5082.

      trace: don't allocate all events upfront · f4b625ec
      Radu Berinde authored 
      SetMaxEvent allocates storage for all events, which is very expensive
if we want to set a high value; even with small values, the
unnecessary allocation of the initial slice is measurable.

We improve the performance by having a few events preallocated as part
of the trace, and appending as necessary. We also co-locate the flags
in event which makes it smaller (by a word).

We also add a set of benchmarks; before and after amortized cost
per-event is shown:

      This reverts commit If7c68bb1809fb92fa5d06cb6640be5e09e1f131f.

Reason for revert: breaks the build for Go 1.6 or below due to use of Go 1.7+ only features.

requires https://go-review.googlesource.com/30171/

Note: Unlike other platforms, Solaris seems to have a few restrictions
on ICMP property access via raw IP sockets. At least applications are
prohibited from using IPV6_CHECKSUM option for ICMP transport.

      http2: in Server, disarm connection's ReadTimeout after first request · 69729301
      Brad Fitzpatrick authored 
      Fix a regression from Go 1.5 to Go 1.6: when we introduced automatic
HTTP/2 support in Go 1.6, we never handled Server.ReadTimeout. If a
user set ReadTimeout, the net/http package would set the read deadline
on the connection during the TLS handshake, but then the http2 package
would never disarm it, killing the likely-still-in-use connection
after the timeout period.

This CL changes it to disarm the timeout after the first request
headers, similar to net/http.Server.

Unlike net/http.Server, we don't re-arm it on each idle period,
because the definition of idle is more complicated with HTTP/2.

No tests here for now. Tests will be in the go repo once all the knobs
are in place and this is re-bundled into std, testing both http1 and
http2.

Updates golang/go#16450 (minimal fix for now)
Updates golang/go#14204 (considering a new http1+http2 IdleTimeout knob)
