whitequark 0134bb7399 Bump Rust version requirement to 1.27. 
This allows us to use:
(1.26)
  - impl Trait
  - autoderef in pattern matching
  - fixed slice patterns
  - inclusive ranges
(1.27)
  - dyn Trait
  - #[must_use] on functions

To prepare for edition change, dyn is added where applicable. Other
edition changes would require bumping the requirement even higher,
and so they are not applied for now.

Kai Lüke 2ac9c77d18 Document that Packetization Layer Path MTU Discovery in TCP is not supported

Kai Lüke 15c6c24a87 Increase number of assembler gaps to 32 for std/alloc targets 
Only allowing four missing packets is hurting
performance for large receive windows.

The new value was picked by observing good
performance with 500 kB socket buffers.

whitequark 0a8a962e94 Reorganize features using namespaces, to match module hierarchy. 
I'm about to add a whole lot more features, and it's going to get
quite confusing otherwise.
 2017-09-24 23:51:19 +00:00

whitequark 2bb1d1bfc1 Clarify README paragraph about features. 
We can easily (although annoyingly) do IP fragmentation with
the assembler now, so I don't see *any* features that are apriori
impossible to implement anymore.

with a higher cost/benefit ratio are higher up.
 2017-09-22 19:49:54 +00:00
whitequark e38ec8f397 Update README. 
We don't really care about fast open one way or another, this entry
was a misunderstanding of RFC 793's behavior wrt data in SYN packets.

whitequark acf4688ad8 README: fix typo. 2017-08-25 06:20:10 +00:00
whitequark afdf73ffef TcpRepr::push → TcpControl::Psh. 
This is done for simplification. FIN implies PSH, RST doesn't have
any meaning with PSH, and SYN|PSH only makes sense in the context
of TCP Fast Open, in the context of which, any data in the original
SYN already implies PSH.
