Hi, i just compiled the 2.6.35-git3 kernel on my computer using debian 64
bit as i did with all other kernels before.
Booting the git2/3 kernel results in a kernel panic because of
/sbin/tomoyo-init.
No problem with the 2.6.35 kernel.
I've to remane /sbin/tomoyo-init to boot the kernel.
Now i purged tomoyo-tools version 2.2.0-20100225 (aptitude purge
tomoyo-tool) and everything works ok.
Sorry, i forgot to backup the tomoyo-init script.

Thank you for using TOMOYO. TOMOYO has changed a lot in 2.6.36. Therefore,
you need to upgrade tomoyo-tools package. I'm testing it now.
You can upgrade it by doing
# wget -O tomoyo-tools.tar.gz 'http://sourceforge.jp/projects/tomoyo/svn/view/trunk/2.3.x/tomoyo-tools.tar.gz?root=tomoyo&view=tar'
# tar -zxf tomoyo-tools.tar.gz
# make -C tomoyo-tools/ install
Then, please delete (or rename) /etc/tomoyo/ directory and run
/usr/lib/tomoyo/init_policy .
Please see http://tomoyo.sourceforge.jp/2.3/ for more information.
Thank you.

Still, if a legacy userspace application is able to cause kernel panic,
that sounds like something we'd rather fix immediately.

I assume the panic message which Karsten encountered is either
Profile version %u is not supported.
or
Profile %u (used by '%s') not defined.
which happens only if access control rules (a.k.a. policy) was not
loaded when /sbin/init starts.
If what Karsten encountered is not the cases above,
I agree that we need to fix immediately.
Regards.

The panic message was:
> Profile %u (used by '%s') not defined.
Profile 0 (used by '0') not defined.

Looking at the code ...
void tomoyo_check_profile(void)
{
struct tomoyo_domain_info *domain;
const int idx = tomoyo_read_lock();
tomoyo_policy_loaded = true;
/* Check all profiles currently assigned to domains are defined. */
list_for_each_entry_rcu(domain, &tomoyo_domain_list, list) {
const u8 profile = domain->profile;
if (tomoyo_profile_ptr[profile])
continue;
panic("Profile %u (used by '%s') not defined.\n",
profile, domain->domainname->name);
}
tomoyo_read_unlock(idx);
if (tomoyo_profile_version != 20090903)
panic("Profile version %u is not supported.\n",
tomoyo_profile_version);
printk(KERN_INFO "TOMOYO: 2.3.0\n");
printk(KERN_INFO "Mandatory Access Control activated.\n");
}
makes one wonder whether not having up-to-date userspace really does
qualify for unconditional kernel panic.
