Description Kevin Fenzi 2015-03-21 09:17:44 EDT

This bug: 

http://bugs.squid-cache.org/show_bug.cgi?id=3849

was fixed upstream, but doesn't seem to be in the current RHEL7 squid package. 

This means if you use ssl with a cert chain, any clients using newer gnutls will be unable to use your proxy. ;( 

We have hit this with a proxy in Fedora, see: https://fedorahosted.org/fedora-infrastructure/ticket/4682 

Please consider backporting this fix. Thanks.

Hi Kevin,

which version of squid and RHEL are you exactly using? I backported this patch, for the latest squid (3.3.8) in RHEL 7.1. I'm attaching the PATCH, so you can try, if it fixes this bug in your squid configuration.
