[gentoo-hardened] openct and stack smashing protector

[Andreas Jellinghaus]

Hi,

if openct 0.6.0 is compiled with stack smashing protector
it dies during normal operatoins:

write(2, "ifdhandler: stack smashing attack in function do_transact",
57) = 57
write(2, "()\n", 3)                     = 3
socket(PF_UNIX, SOCK_DGRAM, 0)          = 6
sendto(6, "<2>ifdhandler: stack smashing attack in function
do_transact", 60, 0,
 {sa_family=AF_UNIX, path="/dev/log"}, 110) = -1 EPROTOTYPE (Protocol
wrong type
 for socket)
rt_sigaction(SIGABRT, {SIG_DFL}, NULL, 8) = 0
getpid()                                = 22083
kill(22083, SIGABRT)                    = 0
--- SIGABRT (Aborted) @ 0 (0) ---
Process 22083 detached

however that functions looks fine to me.
compiled with -fno-stack-protector it works fine.

can you help me to find out, why the ssp comes to this
(false) conclusion? I'd like to improve the code, so it
works with ssp turned on.

Thanks for your help.

Regards, Andreas
