Bug 201923 – =www-servers/apache-2.2.6-r4 SSL-related regression

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Petre Rodan 2007-12-11 09:42:36 UTC]

a large POST triggers the following error for https sites:

[Tue Dec 11 11:22:09 2007] [error] [client 192.168.88.165] request body exceeds maximum size for SSL buffer
[Tue Dec 11 11:22:09 2007] [error] [client 192.168.88.165] could not buffer message body to allow SSL renegotiation to proceed

this only started happening since I updated to apache-2.2.6-r4.
apache-2.2.6-r2 and older worked without ever displaying that error.

the same apache-2.2.6-r4 merged without the 04_all_mod_ssl_tls_sni patch does not have the problem.

so please either fix that patch or drop it.

thanks,
peter

it's masked for a reason ... but if you have a patch, let me know

[Comment 2 Petre Rodan 2007-12-15 11:53:02 UTC]

Created attachment 138538 [details, diff]
apache-2.eclass patch

UNIPATCH_EXCLUDE adaptation for gentoo's apache build.

in case you intend to mark as stable an apache containing that shady patch please also include this eclass tweak.

[Comment 3 Benedikt Böhm (RETIRED) 2007-12-15 12:19:37 UTC]

use EPATCH_EXCLUDE from eutils.eclass

[Comment 4 Benedikt Böhm (RETIRED) 2007-12-15 12:20:29 UTC]

FYI, it will probably become a use-flag as long as it's experimental, to get the USE_EXPANDED ebuild unmasked asap

maybe this is also related to http://issues.apache.org/bugzilla/show_bug.cgi?id=39154 ?

Hi,

I've seen those bug reports, but they do not apply on our infrastructure, because we don't use SSLVerifyClient (or any other per-directory SSL setting), and we never had that error before using an apache with that SNI patch, on any of our production servers.

the error popped up the second day after -r4 has been merged on an internal web server and went away after merging an -r4 without the SNI capability.

having SNI tweakable via USE flag works for me.

thanks,
peter

2.2.6-r6 now has the sni use flag
