Strange behaviour on PCEngines APU2
Hi!
I recently got a PCEngines APU2 (not sure of the exact model) to replace my
failing Soekris gateway and some strange behaviour appeared after I took it in
production.
After the system has been running for a few hours, it seems to stop being able
to send packets on the internal wired network interface (possibly also the
external, I can't tell) on a per-process basis, and seems to mostly affect
IPv4. ICMP and UDP seems more prone to failure than TCP retransmission?).
For instance, if I ping a host on my network from the gateway, only a few icmp
requests go out (checked with tcpdump), sometimes one, sometimes ten but then
it just sits there. The process seems to be stuck in select, if top is to
believed.
Attaching a debugger yields;
(gdb) bt
#0 0x000070e3f803e28a in poll () from /lib/libc.so.12
#1 0x000000002f003a6f in main ()
Once I quit the debugger, sometimes a few packets get sent (and received) again.
Pressing ctrl-c stops the ping process properly, and it says it sent and
received 8/8 packets or whatever.
Disabling pf did nothing.
Packet forwarding seems to work just fine.
I also have a small daemon that I wrote that listens to pflog devices that
decodes the log and sends the messages to syslog. These also seem to stop in
the same maner as ping, but in read() in pcap_loop().
Once the system is in this state, it can't reboot itself either, presumably
waiting something somewhere.
The apu2 is flashed with the latest firmware available, and that made no
difference.
Since this is a new system, I don't know if it's faulty or if netbsd is doing
the strange stuff.
Advice? I will probably try to roll back my sources to this summer sometime
and see if an older kernel works, the kernel that was optimized for my NET6501
appeared to not have the same problem, but I am not sure.
current kernel config:
include "arch/amd64/conf/GENERIC"
# no need for this (no X11)
no options INSECURE
# not a mac
no options DKWEDGE_METHOD_APPLE
# is a gateway
options GATEWAY
# I prefer pf
no options IPFILTER_LOG
no options IPFILTER_LOOKUP
no options IPFILTER_COMPAT
