Re: preprocessor normalize_tcp: ips ecn stream dropping SYN retransmission

Hello all,


I am attaching a temporary workaround (one line patch). Do not know if this could be final fix.

Do not know if this is right fix and do not know if it has any bad side effect.
So use at your own risk.


It atleast resolves (bypasses) the problem I described.

Please do post if you think this has bad side effect or you have better solution.

Thanks


Amm.

Ok. I see there was cvs.snort.org once not anymore.



Is there a way to get patch that went in 2.9.4 fixing this bug?


May be its not sourcefire's policy to release whole 2.9.4 tree before being released but is it possible to get this 
particular patch? It will anyway be open source in a month or so. So may be it should be fine.



Because i think this is a bit serious issue as it causes lot of inconvenience esp. if internet line is showing abt 5% 
packet loss.



Thanks


Amm.
