[Samba] stack smashing problem

[Matthias et Laura]

Hi all,

I have a problem with my smbd daemon, on a hardened linux from scratch 
server :
kernel 2.6.24.6
glibc 2.3.6 with fstack protector
grsecurity 2.1.8 patch
gcc 3.4.5 with stack smashing protector
samba 3.0.22

When starting smbd, I do not have any problem, the daemon is running, 
but all his childs die.
I have the following log message, repeated several times :
smbd: stack smashing attack in function open_sockets_smbd()

So it seems that the open_sockets_smbd function does something that the 
stack smashing protection find weird.
Do you have any idea ?
