Tried the samba mailing list first with no responses, so I was hoping
someone might have an idea on the technical side.

Appreciate any and all assistance.

Subject: Samba 3.0.20b / AIX 5.3 / VFS Modules

Has anyone successfully gotten the VFS modules to work under AIX 5.3 and
Samba 3.0.x ?

I have no problem compiling Samba 3.0.x and having it working; but when
I set up a VFS module the following occurs:

1.  In the log file I see:

	[2005/11/09 15:45:02, 0] lib/fault.c:fault_report(36)
  ===============================================================
[2005/11/09 15:45:02, 0] lib/fault.c:fault_report(37)
  INTERNAL ERROR: Signal 11 in pid 13020 (3.0.20b)
  Please read the Trouble-Shooting section of the Samba3-HOWTO
[2005/11/09 15:45:02, 0] lib/fault.c:fault_report(39)

  From: http://www.samba.org/samba/docs/Samba3-HOWTO.pdf
[2005/11/09 15:45:02, 0] lib/fault.c:fault_report(40)
  ===============================================================
[2005/11/09 15:45:02, 0] lib/util.c:smb_panic2(1548)
  PANIC: internal error

2.  A core file is created and dbx shows:

/usr/local/samba/var:> dbx ../sbin/smbd core
Type 'help' for help.
warning: The core file is not a fullcore. Some info may
not be available.
[using memory image in core]
reading symbolic information ...

IOT/Abort trap in raise.raise [/usr/lib/libc.a] at 0xd1b81ffc
0xd1b81ffc (raise+0x40) 80410014        lwz   r2,0x14(r1)
(dbx)

I get the same messages compiling with IBM C ( v5 ) or GCC ( v4.0 ).  I
also tried to compile it with static vs. shared libraries with no
success.  I compiled the torture files and try loading it with the
vfstest tool and get similar issues as below:

/usr/local/samba/torture:> ./vfstest -d10
Initialising default vfs hooks
vfstest $> load audit
Initialising custom vfs hooks from [audit]
Probing module 'audit'
Probing module 'audit': Trying to load from
/usr/local/samba/lib/vfs/audit.so

/usr/local/samba/torture:> dbx vfstest core

0xd00db9a0 (audit_connect+0xa4) 800c0000        lwz   r0,0x0(r12)

My configure looks like this:

./configure --with-configdir=/usr/local/samba/etc
--with-krb5=/usr/local/kerberos --with-syslog --with-utmp
--with-libsmbclient --with-readline=/usr/local
--with-libiconv=/usr/local/special --with-aio-support

I am using GNU libiconv since the AIX version does not seem to work with
Samba.

My build looks like:

Any help is greatly appreciated.  Trying to get Samba VSCAN working and
the problems seem to be with the VFS module support under AIX.
