            Bug ID: 194265
           Summary: Using arcconf on FreeBSD 11 Current Causes
                    Segmentation Fault
           Product: Ports Tree
           Version: Latest
          Hardware: amd64
                OS: Any
            Status: Needs Triage
          Severity: Affects Only Me

Hello,

This report is concerning arcconf from /usr/ports/sysutils/arcconf. When run as
shown below there is no output except for "Segmentation fault (core dumped)".
My RAID controller is an Adaptec 3405 model.

# arcconf getconfig 1 al

Running arcconf without any arguments or options displays a list of options as
expected beginning with the text shown below.

| UCLI |  Adaptec by PMC uniform command line interface
| UCLI |  Version 1.6 (B21062)
| UCLI |  (C) Adaptec by PMC 2003-2014
| UCLI |  All Rights Reserved


This issue was previously fixed as can be seen in bug report 189668 but seems
to have resurfaced albeit in a slightly different form. When the issue first
occurred in report 189668 my server would drop to a DB prompt and my SSH
session would be terminated. Now I just get the "Segmentation fault (core
dumped)" message.

Incidentally my email address has now changed to pete at valar.uk.net.

If it helps at all, here is some gdb output on the core file.

Here are some more details about my system and kernel.

FreeBSD 11.0-CURRENT #0 r272734 amd64

Custom kernel:

/usr/obj/usr/src/sys/PETEKERN20141008

The only changes I've made are below:

(the "Wireless NIC cards" section is completely commented)

options         ALTQ
options         ALTQ_CBQ        # Class Bases Queuing (CBQ)
options         ALTQ_RED        # Random Early Detection (RED)
options         ALTQ_RIO        # RED In/Out
options         ALTQ_HFSC       # Hierarchical Packet Scheduler (HFSC)
options         ALTQ_PRIQ       # Priority Queuing (PRIQ)
options         ALTQ_NOPCC      # Required for SMP build

device          lagg


The same reported issue occurs on an unmodified GENERIC kernel.

I've also tried to apply the previously created patch but to me it seems like
it's already been included.


# cd

# vim aac_patch

# cd /sys/dev/aac ; patch < /root/aac_patch

Hmm...  Looks like a unified diff to me...
The text leading up to this was:
--------------------------
|Index: aac.c
|===================================================================
|--- aac.c      (revision 266123)
|+++ aac.c      (working copy)
--------------------------
Patching file aac.c using Plan A...
Reversed (or previously applied) patch detected!  Assume -R? [y] y
Hunk #1 succeeded at 1408.
Hmm...  Ignoring the trailing garbage.
done

# arcconf getconfig 1 al
Segmentation fault (core dumped)


Hopefully the information above is sufficient but please don't hesitate to
contact me (pete at valar.uk.net) if you require further information or test
results.

Thanks for your time.

Regards,

Pete.
