Subject: mod_ssl bug

Hey Joe,

Customer: ########
OS: RHEL 2.1 AS
mod_ssl-2.8.12-3 (and mod_ssl-2.8.12-4)
apache-1.3.27-7.ent

Got a customer who had issues with Apache segfaulting on them. We got
Apache to core dump for us and found on that the culprit was mod_ssl.

Cliff Perry has built a new package and tested the fix. It resolves
the issue.

It's a pretty dead simple, small patch. And apparently it has been
fixed... just not in the version of mod_ssl we ship on RHEL 2.1.
Apparently the code is in mod_ssl-2.8.14-1.3.27 or later (Cliff
backported from that codebase).

The patch is attached... here is an email from 2 years ago that
discusses it:
http://www.mail-archive.com/modssl-users@modssl.org/msg15601.html

The relevant issue-tracker, in case you care is:
https://enterprise.redhat.com/issue-tracker/?module=issues&action=view&tid=44192
So... Joe, is is possible to get this patch in?

Our current short term solution is to bump the SSLSessionCacheTimeout
setting from 300 to 60 in httpd.conf.

Do you want me to file a bug on this?

Yes, please file a bug on this and we'll include the fix in future
updates.  (I'd have to check but there were some other fixes for shmht
which might need to be included as well).

But 'shmcb' is the recommended session cache of choice - the best
solution is to simply switch to to using shmcb rather than shmht.

mod_ssl patch

Apparently I forgot to attach the patch. So... here it is.

We are using the "bypass" in httpd.conf (i.e., the SSLSessionCache
setting using shmcb) for our customers. Therefore, a test build is not
necessary for us to fix existing customers. That patch is for you guys
to fix the general problem at this point. Thanks.
