Subject SSL renegotiation bug
Date Tue, 13 Jan 2004 22:43:07 GMT

Hello, Apache folk.  After showing this bug to gstein, iholsman, and
others in IRC, I fear I may have found a real bug.  It has something
to do with SSL, but it's not clear whether this is a bug in the Neon
library, OpenSSL, mod_ssl, or httpd itself.

Client is:  Redhat 9, svn 0.36.0 using neon 0.24.4 / OpenSSL 0.9.7a
Server is:  apache-2.0.48 / mod_dav_svn 0.35.1 / OpenSSL 0.9.6b

The reproduction recipe:

  * the subversion client connects to apache via https://

  * client and server successfully exchange certificates

  * client begins committing a large number of new files:  
       (MKACTIVITY, followed by a really long stream of PUT and
        PROPPATCH requests...)

  * while the commit is in progress, I run 'apachectl graceful'

  * I watch the errorlog, and see that it takes about 5-10 seconds for
    the graceful signal to complete, but it completes successfully.

  * soon afterward, the subversion commit stops in its tracks; neon
    eventually times out.  (If I never run 'apachectl graceful', then
    the commit finishes successfully.)

More information:

  * I originally encountered this bug using neon 0.24.2;  with this
    version of neon, the hang happens within 10 seconds of the
    graceful restart completing.

  * After upgrading to neon 0.24.4, it becomes harder to trigger the
    hang; at least two graceful restarts are required, and the hang
    happens about a minute later.


Tracing the bug:

I set the httpd.conf LogLevel to 'debug', so I could see the maximum
amount of mod_ssl spam.  And there's definitely something going on
with ssl, I just don't understand. 

I've attached output to the bottom of this mail;  perhaps someone
clueful can guess what's going on?  (Joe Orton?)

It looks like something ssl-related on the server has "timed out" and
is trying to renegotiate the ssl session, but is failing.  The server
keeps trying to read bytes in the ssl negotiation, and is getting a
premature EOF in some sort of infinite loop.  Also notice that the
server is trying to renegotiate the ssl connection after a
PUT/PROPPATCH to 'revs-txns.c', but the svn client believes it has
already sent about 10 more files...?!?  It almost looks like HTTP
pipelining or something (but I know neon doesn't really have that.)

Perhaps this is just a neon bug, in which case we can redirect the
discussion to the neon list.  But I'd like people to take a quick look
at the stuff below first.

[.... that's it.  Notice that the commandline claims to have added
about 10 more things beyond this point, but there's nothing in the
access log about it.]

[.... yes, I know that the log says neon 0.24.2, but I've since
upgraded to 0.24.4, and get the same results.]
