Bug ID: 191343
Summary: ipnat error at boot disables active sessions
Product: Base System
Version: 10.0-STABLE
Hardware: Any
OS: Any
Status: Needs Triage
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: freebsd-bugs@FreeBSD.org
Reporter: david.boy...@twc.com
Customer upgraded 2 test systems to release/10.0.0 and then to releng/10.0
(10.0-RELEASE-p5). With same ipnat configuration as used in 9.2-RELEASE, ipnat
didn't create active sessions. Customer then rebooted system and ipnat
functionality returned. A subsequent reboot disabled ipnat again.
Customer reported this problem to me. Skeptically, I agreed to visit site.
The console log for the failing ipnat reports an error at boot:
IP Filter: v5.1.2 initialized, default = pass all, logging = enabled
Enabling ipfilter
Installing NAT rules.
0 entries flushed from NAT table
0 entries flushed from NAT list
in=0x801406600:SIOCSTPUT:no such process
Now the weird part:
On reboot (shutdown -r now) the SIOCSTPUT error is not reported and ipnat
works.
On reboot (shutdown -r now) the SIOCSTPUT error returns and ipnat fails.
After a hard reset or power off/power on the SIOCSTPUT error "always" returns
and ipnat fails (20+ attempts) and then the every other reboot cycle begins
again (50+ attempts).
Hardware is Supermicro PDSME+ motherboard with quad-core Intel Xeon (2.66 Ghz)
and 4 GB memory
I have verified the kernel configuration is simply
include GENERIC
ident SUPERMICRO
I rebuilt customer's system with stable/10 as of 06/20/2014 ... no change.
I have /etc/ipf.rules, /etc/ipnat.rules, /etc/rc.conf, kernel config files in
my possession.
I also have acquired one of the test machines so patching, rebuilding and
testing are possible.
