- Add low level system message distibution framework
- Add support for local Secure Streams to participate using _lws_smd streamtype
- Add apit test and minimal example
- Add SS proxy support for _lws_smd
See minimal-secure-streams-smd README.md
Secure Streams is an optional layer on top of lws that separates policy
like endpoint selection and tls cert validation into a device JSON
policy document.
Code that wants to open a client connection just specifies a streamtype name,
and no longer deals with details like the endpoint, the protocol (!) or anything
else other than payloads and optionally generic metadata; the JSON policy
contains all the details for each streamtype. h1, h2, ws and mqtt client
connections are supported.
Logical secure streams outlive any particular connection and supports "nailed-up"
connectivity regardless of underlying connection stability.
In the case code is composed into a single process, but it isn't monolithic in the
sense it's made up of modular "applications" that are written separate projects,
provide a way for the "applications" to request a callback from the lws event loop
thread context safely.
From the callback the applications can set up their operations on the lws event
loop and drop their own thread.
Since it requires system-specific locking to be threadsafe, provide a non-threadsafe
helper and then indirect the actual usage through a user-defined lws_system ops
function pointer that wraps the unsafe api with the system locking to make it safe.
Remove the auth lws_system stuff and redo it using generic blobs
with separate namespaces. Support pointing to already-in-memory
blobs without using heap as well as multi-fragment appened blobs
eg, parsed out of JSON chunk by chunk and chained in heap.
Support auth the new way, along with client cert + key in DER
namespaces.
This affects max header size since we use the latter half
of the pt_serv_buf to prepare the (possibly huge) auth token.
Adapt the pt_serv_buf_size in the hugeurl example.
