[PATCH 4/7] iphlpapi: Implement IcmpSendEcho2Ex() using nsiproxy.
This results in a small change in behaviour reflected by the change to the tests: previously IcmpCreateFile() would fail if neither a SOCK_RAW nor a SOCK_DGRAM socket were available. With this patch, that failure is delayed until IcmpSendEcho2Ex(). There's no evidence that the original behaviour matches Windows; it's likely the tests were written this way to match Wine's implementation. If there does turn out to be an app that depends on the old behaviour, it would be possible to send an ioctl during IcmpCreateFile() to probe for this.

Hi Huw, I had some patches that implement the async requests for IcmpSendEcho2Ex, but obviously now it's completely different so need a rewrite. My question is if you had planned to look into implementing them as well, or should I try to when I have the time?

I haven't any patches waiting, but it should be straight forward now since the request is already asynchronous. Feel free to give it a go. Looking briefly at your patches, I suggest you don't try to implement the "waiting for the request to finish in IcmpCloseHandle()" behaviour unless you have an app that actually needs that. Huw.

Huw.
Ok, I updated them now and sent. I decided to keep the wait for requests to finish, but I moved them to a separate patch at the end of the series (so it can be easily discarded if you dislike it). However, I vastly simplified it to a simple polling loop, because it shouldn't be common anyway and this keeps it extremely simple. However, on the off-chance that some app does rely on this, for example to free its buffers after it closes (when it gives up on the echo at all), it avoids a very painful debugging experience with corrupted memory contents and the like... so I honestly think it's worth it. Thanks, Gabriel
