This is concerning to me and not something I expect from an enterprise product.  I think I've mentioned this before 
but Windows XP is still supported after more than 10 years.

So as soon as a new "three digit" release comes out, the old stuff is not supported?  What about all the snorts in 
embedded devices (over 100 from what I read)?  What about bugs?  For example, 2.9.0 comes out and according to this 
thread, there are bug with HTTP inspect and stream reassembly.  But people are forced to upgrade since 2.8.x is no 
longer supported.  But then they upgrade to a buggy version that can be bypassed and it seems like catch-22.

Now I am curious, what is the support model for Suricata?  I know ET Pro supports rules back to 2.4 but does 
OISF/Suricata adopt the same stance as Sourcefire here?


I feel your pain, that's one reason we exist. We will continue to support all the way back to 2.4 as long as it is used 
by customers. We have several that are using our rules for embedded devices that have no capability or benefit from 
upgrading. 

Same with suricata. We'll support old versions back as long as they're in use. 

If we hit the 10 year mark on 2.4 then we can take a second look, or stop adding new rules. But we'll not discontinue 
distributing what exists for certain.

I guess I'm confused here ... I thought "support" for Snort was
current version and current version minus 1.  What you say says
"support" is current version and current version minus zero.  When did
this happen?

There was an issue in that HTTP inspect wasn't correctly handling
raw vs. stream reassembled packets when looking at HTTP response
data.  This fix is included in 2901 -- refer to ChangeLog (changes
to hi_client.c/hi_server.c).

As to the support of 2.8.6, with the release of 2.9.0, 2.8.6.x
is no longer supported.  When there is a new "3 digit" release no
further patches are made to the previous version of Snort.

Hello. Does this release fix the issue where the HTTP pre-processor
wasn't properly examining reassembled data across fragmented packets?
(I don't know the exact cause of the bug - maybe it was the other way
around and Stream5 wasn't properly doing the reassebly.)  It was
announced that there would be a patch for that issue, just want to see
if this is it.  If so, when can we expect the 2.8.6.1 patch be
released?  2.8.6.1 is still supported, right?

Thanks!

Snort 2.9.0.1 is now available on snort.org, at
http://www.snort.org/snort-downloads/.

2.9.0 RC & later packages are signed with a new PGP key
(that is signed with the previous key).

Snort 2.9.0.1 addresses the following:

 * Fixed maximum flowbits configuration parsing to specify the number
   of bits in accordance with the Snort manual, rather than number of
   bytes.  If you have 'config flowbits_size' in your snort.conf,
   double check that it has the correct setting.

 * Fixed a packet size issue with the IPQ and NFQ DAQs.

 * Fixed issue with Stream5 overlap limit processing.

 * Updated the version of LibPCRE bundled with the Windows installer.
   This update fixes a bug that caused some PCRE matches to fail
   on Windows.

Please see the Release Notes and ChangeLog for more details.

Please submit bugs, questions, and feedback to snort-beta () sourcefire com 

Happy Snorting!
