ziti-sdk-c's Issues

multiple calls to nf_conn_cb on failed connection

Scenario:

Attempt to connect to a service that is not available
nf_conn_cb is called with "Service not available"
nf_conn_cb is called again with "Operation did not complete in time"

Expected:

nf_conn_cb is only called once (so app developer knows it's safe to clean up resources if the call indicates an error connecting the service)

Service Update event should not trigger if only posture checks are changed

Service unavailable event should trigger for services failing posture checks

implement support for half close on ziti connections

Handle session invalidation on Dial attempt

Passing bogus config file location to NF_init() will cause SDK to crash

Currently, the stack variable cfg is not initialized by load_config() if it fails to find a valid config file. The subsequent call to free_nf_config(cfg) will cause an attempt to free a bogus memory location because the cfg variable contains garbage.

This error currently manifests in a MattermoZt arena as a spinning logo during the init/connect sequence, because the SDK crash terminates the Electron renderer process.

Would like a method or callback for status of the network controller

Is it online/available? In an error state? Is the status current or is it from some timeAgo?

Add option to build shared library

Use UTC for log messages

Time since startup is "ok" for log messages but it's really hard to read as a human. It'd be much better to have the log output UTC time instead.

Local time is easier for users but for debugging purposes it's probably easier to use UTC?

Expose SDK version info in top-level API

Add a NF_version() API that exposes the SDK's version info to consuming apps. This will be a nice trouble-shooting / support tool.

Multiple simultaneous calls to NF_init() hangs the C-SDK

to reproduce, just call NF_init() multiple times in a row:

     NF_init();
     NF_init();
     NF_init();

The NodeJS-SDK, while handling some startup sequences in an Electron app, sometimes does multiple NF_init() calls to the C-SDK, and experiences hangs.

ziti_shutdown doesn't guard against NULL/incomplete intialized context

I had a context which did not fully initialize due to failed to login: INVALID_AUTH[-12](The authentication request failed). When that context is passed to ziti_shutdown ztx->session is NULL and free_ziti_session(ztx->session); will cause a crash

Add hexdump/trace capabilities

updating a configuration in controller doesn't result in callback

When renaming a service the CSDK will get two service callbacks - one with ZITI_SERVICE_UNAVAILABLE and one with ZITI_OK. This will allow an sdk-based app to remove an intercept/add it back properly.

If the config for that service changes - the CSDK will get a service callback with ZITI_OK only.

steps to reproduce

establish a service in controller
establish a csdk session to the service
update the service's config
observe ZITI_OK callback only

implement default posture callbacks

make Posture Query type enum

crash with more than 10 services

Add event for blocked connection due to MFA

I have enabled MFA on an my chat-enabled identity. Right now when I wake my laptop from sleep I am required to MFA yet to the chat app it appears as though I have no connection. It would be useful for a tunneling app (or a ziti-integrated app) to realize MFA was necessary at that time and prompt the user

Provide list of services and notify on change

Could be separated into two issues:

Allow retrival of current services and configurations
Notifiy when service changes (e.g., by callback)

rework ziti_close() and ziti_connection lifecycle

fix/improve constency of ziti_connection lifecycle:

currently ZITI_EOF must be handled differently from other errors by the application code
may need to require app to call ziti_close() even after receiving error on ziti_conn
ziti_close() with a callback -- make it closer to libuv standards

Connection:close from client causes error

When a client sends an HTTP request via um_http_req and the request includes a Connection:close header, the request fails with the following:

ERROR _deps/uv-mbed-src/src/http.c:74 connection error before active request could complete -4095 (end of file)

add ARM build for all

SDK crash if identity.json ztAPI field contains bad host

Better payload handling

avoid hitting fabric MTU (split up large writes)
allow app to specify stream semantics: coalesce small writes

improve controller communication

request to controller should be made on the event loop instead of background thread
enable periodic polling of available services

handle ER becoming unavailable

SDK keeps trying to connect to defunct edge routers

Implement disabling/enabling of Ziti context

Here is the things that happen on disable:

active ziti_connections are disconnected, appropriate callback receives ZITI_DISABLED error code
ZitiServiceEvent is sent with all current services removed
connections to Edge Routers are closed, with corresponding ZitiEdgeRouteEvents
ziti_context terminates API session (controller /logout), with corresponding ZitiContextEvent
all model data (services, sessions, api session) is freed

if context is disabled it can be re-enabled/restarted by calling ziti_set_enabled(ztx, true). Re-enabling puts it back into
running state

nf_connection is leaking

Right now it seems as though NF_close would reclaim the memory for a connection but the connection is not getting free'd.

README for sample_http_link

sample_http_link.c, both as client and server need a quick write up on how to use ziti cli to use the samples. let's make a quick README.md

C-SDK proxy 100%

ziti_get_identity returns ziti_identity without tags

the c sdk appears to be parsing the response from /authenticate?method=cert in order to hydrate the ziti_identity however this endpoint returns an api-session and not an actual identity. This leaves the tags null.

Please provide a mechanism to fetch the tags for a given identity.

SDK crash when no edge routers are present in session (net_session)

broken crypto on c-sdk hosted services

NF_shutdown should free all memory

NF_free is going to be removed soon so NF_shutdown should reclaim memory for the nf_context.

Improve Edge Router connection life-cycle

some ideas:

keep failed edge router connections to avoid high connection attempt churn
expose edge routers status to the app

Edge API version(prefix) support

SDK crash after connect time out

timeout frees up connect request, and when connection accept message comes in SDK gets SEGV when trying to finish connection processing

Issues building library package for CentOS/RHEL 8

My first attempt at building a library package for ziti sdk shared library fails around libsodium.
Since the distribution has already libsodium, I have installed libsodium-devel and essentially running cmake with -DHAVE_LIBSODIUM=ON however that fails with:

Unknown arguments specified

Whether I pass it as a cmd line option to make or change the option to default to ON in CMakeLists.txt, the same thing happens.

CRASH: Unaddressable router causes crash

Created multiple edge routers - one edge router is 'private' (others are all public)
last error shown before crash is:

first message from hosting side gets dropped on accepted connection

Provide name of enrolled identity

The identity name is no longer part of the JWT and want to show it in the UI. Also need to support updating when name changes (either allow it to be queried again or notify via a callback when it's available or changes)

clients unable to connect to hosted services after hosting channel is reconnected

I've been seeing this often when trying to connect a service after my dev box wakes up from sleep:

Connections succeed after the hosting tunneler is restarted.

Authenticated sessions needlessly set to partially authenticated

right now when you launch a sample program, the programs check the ctrl_status and this status is evented as "partially authenticated" at the wrong time. Update the csdk to not emit that event if not accurate

on upgrade - UI does not reflect new version information

The UI appears to need to be restarted before it notices the updated version information
