Re-based old PPAPI VPN Provider proposal and split it into three separate reviews. ppapi: https://codereview.chromium.org/1726303003/ naclsdk: https://codereview.chromium.org/1731273002/ browser: https://codereview.chromium.org/1735473002/

This patch contains the browser part. Unfortunately this is, this approach contains .DEPS workarounds that were good enough for the PoC, but it's not production ready. What would be the best approach to move packets and messages between the PPAPI resource host and the shill DBUS client? My best guess would be a new instance of ShillThirdPartyVpnObserver specially for the PPAPI path, but that would contain a lot of code duplication with the VPN Service from the extension. I really appreciate any help with solving this architecture problem.
+Kevin to ensure any changes here don't conflict with the robustness improvements currently in flight.

The 'ChromeOS' in the class name is indeed redundant. But the "_chromeos" in the file name is needed to further ensure that this is build only on Chrome OS.

Considering the typical usage as described in the IDL https://cs.chromium.org/chromium/src/ppapi/api/ppb_vpn_provider.idl a plugin must call Bind() each time the connection connects to explicitly route packets through NaCl. The alternative would be that for each reconnect the PPB_VpnProvider instance to be recreated, which would be cumbersome. The following sequence must work: Create -> (Connect -> Bind -> Disconnect)* -> Destroy. https://codereview.chromium.org/1735473002/diff/440001/content/browser/render... content/browser/renderer_host/pepper/pepper_vpn_provider_message_filter_chromeos.cc:177: FailureCallback failure) { On 2016/06/23 18:10:22, bbudge wrote: > nit: s/success/successCallback or successCb, ditto for failure.

How can it be bypassed?

Neither renderer_process_host or browser_context should be NULL at this point. While experimenting with this I have not encountered that use-case. While the error checking on this may be superfluous, it sure isn't a hindrance to performance and can only increase robustness for that corner case. Also, looking at how this is used, those two are usually NULL-checked. https://cs.chromium.org/chromium/src/content/browser/renderer_host/pepper/pep... https://codereview.chromium.org/1735473002/diff/560001/content/browser/render... content/browser/renderer_host/pepper/pepper_vpn_provider_message_filter_chromeos.cc:101: return NULL; On 2016/07/04 04:24:07, dcheng wrote: > Nit: nullptr Done. https://codereview.chromium.org/1735473002/diff/560001/content/browser/render... content/browser/renderer_host/pepper/pepper_vpn_provider_message_filter_chromeos.cc:212: send_packet_buffer_ = base::WrapUnique(new ppapi::VpnProviderSharedBuffer( On 2016/07/04 04:24:07, dcheng wrote: > Nit: base::MakeUnique here and below.

I would prefer that allocation testing is done here, not in the success handler. If CreateAndMapAnonymous(kBufferSize) fails for some reason, we would need to unbind in VpnService, thus making the flow a bit convoluted. It's much simpler to test the shm allocation here.

There may not be a large perf cost, but there is a cost to the code reader: now the reader needs to figure out if there is an exceptional case where this can happen, and how to handle it. It also means we need to try to gracefully handle cases that should never happen in practice, resulting in more lines of unused code. There are a few other ResourceMessageFilters that call this function, and they don't bother checking the result, or they guard it with NOTREACHED(). That's probably the pattern we should be using here. https://codereview.chromium.org/1735473002/diff/560001/ppapi/proxy/ppapi_mess...

That's > probably the pattern we should be using here. Cleaned up the code here as follows: - Removed GetRenderFrameIDsForInstance check. (On failure render_process_id will be 0, thus RenderProcessHost::FromID will return NULL). - Removed browser_context check. (nullptr check eventually happens in KeyedServiceFactory::GetServiceForContext). The only needed check is for RenderProcessHost::FromID. https://codereview.chromium.org/1735473002/diff/560001/ppapi/proxy/ppapi_mess...

LGTM with a nit https://codereview.chromium.org/1735473002/diff/600001/content/browser/render...

Then we can skip this check. This if () statement should *always* be true, so having it structured like this still implies that this can somehow fail.

Added two DCHECKs (one for GetRenderFrameIDsForInstance and one for FromID). Should now be OK.
