 |
|
I upgraded one of our servers to 1.4.19.1 last evening, but ended up
having to drop back because of IAX calls failing at a near 50 % rate.
Here is the message that we would receive on the console (multiple
times), and then it would hangup the call.
Avoiding IAX destroy deadlock
Anyone else having similar problems?
Thanks,
Mike Clark |

From the 1.4.20-rc1 Changelog:
2008-04-30 16:30 +0000 [r114891] Russell Bryant <russell at digium.com>
|
So basically, r114891 was a fix to AST-2008-006? So if you applied the
patch for AST-2008-006 you now really need this new fix (r114891) to
regain the stability that chan_iax2.c had before the AST-2008-006 patch?

Hrm. For those of us that are following along the AST-* train, patching
as per the AST-* release notices, as a matter of process, wouldn't it
have been good to republish AST-2008-006 and include this fix along with
the original patch?
IOW, IMHO, it should be standard practice that when you release a fix to
a patch in an AST-* security release, that you re-publish the security
notice complete with the original security fix and the security fix fix.

It's not actually a fix to the security fix. The security fix simply
highlighted an issue which was already present in Asterisk. You would
have seen this same issue prior to the security fix simply by running
'iax2 show channels', as that command runs through every single slot
in the channel array, looking for active channels. The security issue
fix simply made that slow search process (already there, nothing new)
painfully obvious.

I agree with you.
I am in the process of working on the Asterisk 1.2.20 release, which will
contain this IAX2 fix. However, you have convinced me that this fix should be
released against the previous security release, as well.
So, tomorrow, I will make an Asterisk 1.4.19.2 release, which includes this one
change. As a part of making that release, it will come with a patch against
1.4.19.1, which will include the changes needed to make IAX2 usable again, if
people needed the patch for a custom version.
I will also update the security advisory to note the effects of the original
changes to address the security issue.
I will then publish announcements as usual that to hopefully notify everyone
that doesn't closely monitor commits to Asterisk, or other high volume Asterisk
mailing lists.
Thanks for the feedback,
