Ok here is how I have simulated what you are trying to do.
cp /bin/sh /var/www/httpdsh
chcon -t httpd_exec_t /var/www/httpdsh
Add the following lines to
/etc/selinux/targeted/src/policy/domains/misc/local.te
domain_auto_trans(unconfined_t,httpd_exec_t, httpd_t)
allow httpd_t devpts_t:chr_file rw_file_perms;
cd /etc/selinux/targeted/src/policy/
make load
setsebool httpd_tty_comm=1
Then run
/var/www/httpdsh
as root.
/var/www/httpdsh
httpdsh: /root/.bashrc: Permission denied
# id
uid=0(root) gid=0(root)
groups=0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel)

Ok, thx for the lines. It works fine when im in Xmode (xterm), but
when i change to console mode (tty1) if i execute /var/www/httpdsh it
doesnot work. Its like if i dont execute the program. I dont get to
the httpd bash. I dont receive any message in the console. I dont
receive any message in /var/log/message. I dont receive any message in
/var/log/audit/audit.log. Its like if it had not done anything
What happen?
You need to add getattr and ioctl to your tty. I am adding it to Policy.
You could add
allow httpd_t tty_device_t:chr_file { getattr ioctl };
to local.te
