Leaking mbufs on 6.4

Lévai, Dániel
Hi!

I have mbufs leaking after introducing a network topology change on a
router:

After a reboot + 20 minutes:
   1 users Load 0.46 0.38 0.33                     16:40:43
IFACE             LIVELOCKS  SIZE ALIVE   LWM   HWM   CWM

                             4096   128          20
                             9216    17          12

After one day:
   1 users Load 0.53 0.40 0.32                     16:14:53

                             2112    69          23
                             4096   128          21
                             9216    17          19

After two days:
   1 users Load 0.14 0.20 0.22                     15:00:00
IFACE             LIVELOCKS  SIZE ALIVE   LWM   HWM   CWM
System                    0   256  215K       13780

                             2112    66           9
                             4096   128          25
                             9216    11          11

I think this is either caused by starting to use an on-board re(4)
device or starting to use vether(4) in a bridge(4) (dmesg, details
below).

In any case, 1 gigs worth of memory is consumed in about two days (give
or take a couple of hours) with mild internet traffic (pppoe connected
to re(4)).

I was given the advice to inquire/report here, maybe someone can help
track down the root cause.

Any help is appreciated!


This is my original e-mail [1] sent to misc@ (minus the writing about
the processes running), it has a bunch of information, if someone's
interested:

<TL;DR>
After a recent network configuration change (added re(4), vether(4)) I'm
experiencing this memory leak from somewhere.

How can I check/query how much memory the kernel (or parts of it) is
using over time, besides running top(1) with system processes shown --
I'm also staring at systat(1)'s `malloc' and `pool' views but I'm not
really sure what I'm (or rather what I should be) looking at.
</TL;DR>


I have an on-board Realtek NIC and an add-on Intel PCIe 4 port NIC.

re0 at pci3 dev 0 function 0 "Realtek 8168" rev 0x0c: RTL8168G/8111G (0x4c00), msi

em0 at pci1 dev 0 function 0 "Intel I350" rev 0x01: msi
em1 at pci1 dev 0 function 1 "Intel I350" rev 0x01: msi
em2 at pci1 dev 0 function 2 "Intel I350" rev 0x01: msi
em3 at pci1 dev 0 function 3 "Intel I350" rev 0x01: msi

Before I started to experience the leak I had the on-board NIC disabled
in BIOS and only used two ports of the Intel NIC. My setup looked like
this:


== Network

ISP --- pppoe0 <-> em0 -- OpenBSD 6.4 -- em1(dhcpd) --- [switch] LAN
                                      `- athn0 --- LAN
                                      `- athn1 --- LAN
                                      `- bridge0(em1, athn[01])

Internal IP configured on em1.
athn? devices don't have IPs, just bridged to the internal network.
dhcpd(8) is running on em1.


Now I started to use re0 and one more NIC on the Intel card:

ISP --- pppoe0 <-> re0 -- OpenBSD 6.4 -- em0 --- LAN
                                      `- em1 --- LAN
                                      `- em2 --- LAN
                                      `- athn0 --- LAN
                                      `- athn1 --- LAN
                                      `- vether0 (dhcpd)
                                      `- bridge0(em[123], athn[01], vether0)

Now the 4 port Intel NIC basically acts as a switch, the em? interfaces
don't have IP addresses configured, and the athn? interfaces don't have
one either.
I've added a vether(4) interface with an internal IP (same as the em1
have had before) to the bridge, and dhcpd(8) (and everything else that
needs it) now uses that interface.

Nothing fancy, just basically a "software switch" for connecting
separate rooms in the house and adding a vether(4) interface for
conveniency.

Also, everything else remain unchanged, i.e.: no additional services
running, no new software has been installed, no introduction of new pf
rules, other than replacing the interface names of course.

I'm using /etc/malloc.conf@ -> S on all my machines but never had any
problems with it (and still don't anywhere else).


== pf(4)

pf(4) is used on the box, and the rules that have been changed are the
ones related to the interfaces mentioned above:

set skip on lo0
set skip on bridge0
pass on vether0 all flags S/SA allow-opts
pass on em0 all flags S/SA allow-opts
pass on em1 all flags S/SA allow-opts
pass on em2 all flags S/SA allow-opts
pass on em3 all flags S/SA allow-opts
pass on athn0 all flags S/SA allow-opts
pass on athn1 all flags S/SA allow-opts
match in on vether0 inet proto tcp from 192.168.0.0/16 port = <port> to any set (prio(2, 6), queue(ssh_bulk, ssh_rt))
block return on vether0 proto tcp from any to any port = 25
block return on em0 proto tcp from any to any port = 25
block return on em1 proto tcp from any to any port = 25
block return on em2 proto tcp from any to any port = 25
block return on em3 proto tcp from any to any port = 25
block return on athn0 proto tcp from any to any port = 25
block return on athn1 proto tcp from any to any port = 25

Previously I've had `skip' on athn? as well.

(I can upload the complete rule set somewhere if it is of interest)
