N A closed ASTERISK-30221.
--------------------------
Resolution: Suspended
I'm pretty sure this is a bug with group vars, so closing for now as that's unmerged code, and will take up the issue separately there.
If further testing reveals otherwise, will reopen this.
> Channel masquerades screw up groups
> -----------------------------------
>
> Key: ASTERISK-30221
> URL: https://issues.asterisk.org/jira/browse/ASTERISK-30221
> Project: Asterisk
> Issue Type: Bug
> Security Level: None
> Components: Core/Bridging, Functions/func_groupcount
> Affects Versions: 18.14.0
> Reporter: N A
> Severity: Major
>
> RELATED to: ASTERISK-30210
> So circling back to the weird thing with masquerades:
> I don't think it has anything to do with optimizations, per se, I think it's the masquerade itself. For some reason, it seems to consistently screw up groups.
> Here is an example of a system caught red handed where, after a masquerade occurs, suddenly all of the groups on all channels on the system suddenly become assigned to a *SINGLE* channel. This includes the bizarre scenario of also having the same group assignment twice on the same channel, such that GROUP_COUNT returns 2 even those there is only one channel in the group. This has the effect afterwards of putting the channel into an infinite loop due to dialplan logic that expects 2 channels.
> None of this happened prior to upgrading from 18.9.0 to 18.14.0, so a regression is possible but I'm not yet positive either. It also seems weird that masquerades would be broken in such a a fundamental way.
> The group screwing up seems to vary: the example in ASTERISK-30210 simply made all the groups disappear, in this case they all hop onto a single channel even from other channels that still exist (as well as groups that no longer do so).
> Note also that this system includes the group variables patch on Gerrit and testing without that is difficult/impossible. The bug could very well be there too, though that doesn't explain why it's only triggered by masquerades.
> UPDATE - POC test with base 18.14.0 shows no issue, so likely related to func_groupcount.c changes
