Re: Apache httpd 2.4.x on Windows

Good news! Gianugo and Claudio have offered to see how they
can help us in resolving the SSL issues w/ httpd 2.4.x...
As you can see, Claudio is the main guru who may be able
to provide the most insight.

I've CC'ed both on this Email.

Claudio, if you like, you may wish to subscribe to the dev [at] httpd
mailing list.

Re: Apache httpd 2.4.x on Windows [In reply to]

Very cool :)

Claudio, we can point you precisely to where httpd 2.4 goes off the
rails. We instantiate a socket connection (accept() or AcceptEx()
yet our presumptions about the state of the socket (block/nonblock
timeouts etc) were not honored. There is a call, apr_os_socket_make()
which APR makes certain assumptions about.

Seems too fragile. Perhaps that _make() call needs to IoCtl at the
socket to determine all of the 'anticipated' state conditions to be
able to roll on with the correct assumptions.

All the notes are in the dev@ list archives this past quarter.

People weren't terribly good about keeping the subject lines
consistent, though. I'm sure Jim, Steffen or someone would be
happy to assemble you the pointers to all the relevant threads.
In short mod_ssl expects a blocking socket connection to the
client, an apr_sock_t object in APR-speak.

If I had time to find you all the scattered threads, I really
would find time to debug this myself :)

To Start there is the bugzilla report;
https://issues.apache.org/bugzilla/show_bug.cgi?id=52476

Then it's scattered all over the dev@ list, possibly the most relevant;

http://marc.info/?t=132500100700005&r=1&w=2
http://marc.info/?t=132914149900007&r=1&w=2

Have missed some I'm sure, but it's a start.

Cheers,
Gregg

Really?�I totally haven't kept up, but last I knew mod_ssl used the
whole bucket nightmare and did not need blocking connections.

RE: Apache httpd 2.4.x on Windows [In reply to]

- Is the listening socket in blocking or non-blocking mode?
- Are you doing overlapped AcceptEx?
- If yes, is it done through IOCP?
- After accepting a connection, do you call setsockopt with SO_UPDATE_ACCEPT_CONTEXT on the accepted socket?
- Do you put the accepted socket into blocking or non-blocking mode?

Thanks
Claudio

It does when it goes to re-attempt a second read() for the HELO. If
that second chance won't block, it appears to barf.
