Fatal error: services/mesh.c:601: mesh_state_delete: assertion mesh->num_detached_states > 0 failed

Unbound

Hello,

I just had unbound 1.4.17 die (on RedHat 6 Update 3 x86_64 linux) with:

unbound: [1387:1] fatal error: services/mesh.c:601: mesh_state_delete:
assertion mesh->num_detached_states > 0 failed

I've also experienced(1.4.17) crash with:
unbound: [23685:3] fatal error: services/mesh.c:742: mesh_state_attachment: assertion n != NULL failed
(but I think this is already fixed on svn).

(No crashes with unbound-1.4.16).

Hello,

Sorry, the version I was using was/is 1.4.17 with
this patch:
http://www.uku.fi/~jhuuskon/unbound-1.4.17-r2683mesh.diff
(pulled from svn: r2683 bug #452: fix crash on assert in
mesh_state_attachment.)

Hi Jarno,

Hello,

I just had unbound 1.4.17 die (on RedHat 6 Update 3 x86_64 linux)
with:

unbound: [1387:1] fatal error: services/mesh.c:601:
mesh_state_delete: assertion mesh->num_detached_states > 0
failed

Sorry, the version I was using was/is 1.4.17 with this patch:
http://www.uku.fi/~jhuuskon/unbound-1.4.17-r2683mesh.diff (pulled
from svn: r2683 bug #452: fix crash on assert in
mesh_state_attachment.)

This seems to be the same flaw as bug#452 on our bugtracker, (even
though it triggers a different assertion here). I have fixed it,
available in svn trunk. (the updates to services/mesh.c should be
sufficient in case you do not wish to incorporate the other changes in
svn trunk in your production).

Thank you for the report, it helped me track down the problem, it was
caused by code introduced in 1.4.17 (as a bugfix for something else,
of course).

Best regards,
   Wouter

Will there be a 1.4.18, or is there a patch that just addresses this
issue? I'm asking because 1.4.17 is in rawhide, and I was about to
push it into F17/RHEL.

Thank you for the fix. I pulled r2718 change from svn
and I'll report if there's any more problems.

PS. Paul: I think you can get patch from svn:
     svn diff -r2682:2683 services/mesh.c
     svn diff -r2683:2718 services/mesh.c
