bind 9.16.6 on FreeBSD - Assert

From Borja Marcos@21:1/5 to All on Tue Sep 1 17:12:39 2020

Hi,

I had a named process aborting with an assert.

<26>1 2020-08-27T15:52:04.000000+00:00 host named 6520 - - rbt.c:2355: REQUIRE(newbits <= rbt->maxhashbits) failed, back trace
<26>1 2020-08-27T15:52:04.000000+00:00 host named 6520 - - #0 0x43d260 in ?? <26>1 2020-08-27T15:52:04.000000+00:00 host named 6520 - - #1 0x62035a in ?? <26>1 2020-08-27T15:52:04.000000+00:00 host named 6520 - - #2 0x514868 in ?? <26>1 2020-08-27T15:52:04.000000+00:00 host named 6520 - - #3 0x515616 in ?? <26>1 2020-08-27T15:52:04.000000+00:00 host named 6520 - - #4 0x529c7d in ?? <26>1 2020-08-27T15:52:04.000000+00:00 host named 6520 - - #5 0x579df7 in ?? <26>1 2020-08-27T15:52:04.000000+00:00 host named 6520 - - #6 0x645e1c in ?? <26>1 2020-08-27T15:52:04.000000+00:00 host named 6520 - - #7 0x80225e036 in ?? <26>1 2020-08-27T15:52:04.000000+00:00 host named 6520 - - exiting (due to assertion failure)
<6>1 2020-08-27T15:52:04.091803+00:00 host kernel - - - pid 6520 (named), jid 0, uid 53: exited on signal 6

I have a full log of queries (it’s a recursive only server) and I haven’t seen anything unusual before the crash. Unfortunately the
program was stripped, I have recompiled it with debug symbols.

It is bind 9.16.6, built from ports on FreeBSD 11.3.

Any hint on what to look for? Fortunately I have another server running 9.11. It wasn’t affected.

Thanks!

Borja.

Looks like that. I compiled bind with debug symbols and it crashed again.

No way to append this to your bug report, it’s closed.

It looks like the same bug to me. - Did you try to patch your source code with the path isc just made?

It looks like the same bug to me. - Did you try to patch your source code with the path isc just made?

No, I am not aware of a patch. I have rolled it back to 9.11 for now, it’s a production server.

Thanks,

Borja.

The server is dualstack and serves DNS via both IPv4 and IPv6.

Has anyone observed something similar?

No, I haven’t seen this one.

If you have used the ports subsystem, can you recompile the port with the WITH_DEBUG option?
Doing that the backtrace will include the function names.

Best regards,

Borja.
