Subject: Initcall ordering problem (TTY vs modprobe vs MD5) and cryptomgr problem


My test box is imploding during boot due to an init ordering problem between
md5 and /dev/console and modprobe failure. Furthermore, the md5 module isn't
finding cryptomgr, despite it being compiled in and initialised.


I've made __request_module() print some stuff and I've set initcall_debug=1 on
the command line, and what I see is this:

(1) The compiled-in MD5 crypto module tries to load the cryptomgr module
during the initcall phase of boot up:

calling md5_mod_init+0x0/0x12 @ 1

============================================

(2) modprobe can't find the cryptomgr module (because it's not installed
where modprobe wants to look). modprobe then attempts to open
/dev/console, presumably to write an error message to it:

============================================
__request_module(char-major-5-1)

============================================

(3) However, since tty_init() hasn't been called yet, /dev/console's driver
isn't yet registered, which means modprobe gets called to load the
driver. modprobe can't find a driver module for char-major-5-1 since
one doesn't get built, so modprobe attempts to open /dev/console,
presumably to write an error message to it:

============================================

============================================

However, this exposes another apparent problem: the 'cryptomgr' module is
actually built in:

CONFIG_CRYPTO_ALGAPI=y
CONFIG_CRYPTO_ALGAPI2=y
CONFIG_CRYPTO_AEAD=y
CONFIG_CRYPTO_AEAD2=y

CONFIG_CRYPTO_HMAC=y
CONFIG_CRYPTO_MD5=y
CONFIG_CRYPTO_SHA1=y
CONFIG_CRYPTO_DES=y
CONFIG_CRYPTO_FCRYPT=y
CONFIG_CRYPTO_DEFLATE=y

but it's not being found by the crypto routines. By GIT bisection, I note
that this problem is introduced in the following commit:

commit 0b767f96164b2b27488e3daa722ff16e89d49314
Author: Alexander Shishkin <[email protected]>
Date: Thu Jun 3 20:53:43 2010 +1000

crypto: testmgr - add an option to disable cryptoalgos' self-tests

By default, CONFIG_CRYPTO_MANAGER_TESTS will be enabled and thus
self-tests will still run, but it is now possible to disable them
to gain some time during bootup.

though I don't really see why. The preceding patch:

commit bc94e59662c13516d13e117b6edab4bec487d5a0

crypto: pcomp - Fix illegal Kconfig configuration

The PCOMP Kconfig entry current allows the following combination
which is illegal:

ZLIB=y
PCOMP=y
ALGAPI=m
ALGAPI2=y
MANAGER=m
MANAGER2=m

This patch fixes this by adding PCOMP2 so that PCOMP can select
ALGAPI to propagate the setting to MANAGER2.

seems to be okay.

Without any alterations to the code, I see the following in the kernel output:

request_module: runaway loop modprobe char-major-5-1

request_module: runaway loop modprobe char-major-5-1

Indeed this changeset is buggy. It makes cryptomgr return a value
as if it was not loaded. This triggers the module load.

I'll send you a patch.

This patch should do the trick:

crypto: testmgr - Fix test disabling option

This patch fixes a serious bug in the test disabling patch where
it can cause an spurious load of the cryptomgr module even when
it's compiled in.

It also negates the test disabling option so that its absence
causes tests to be enabled.

The Kconfig option is also now behind EMBEDDED.

Why do you still want to force-enable those tests? I was going to
complain about the "default y" anyway, now I'm _really_ complaining,
because you've now made it impossible to disable those tests. Why?

People always think that their magical code is so important. I tell
you up-front that is absolutely is not. Just remove the crap entirely,
please.

Even if he does remove it, that still leaves the problem that modprobe can be
invoked and fail before tty_init() gets called:-/

I wonder if tty_init() should be moved up, perhaps to immediately after
chrdev_init().

I do think that sounds sane. The tty layer is kind of special.

I wouldn't call it _after_ chrdev_init(), though, I'd call it _from_
chrdev_init(). Doesn't that make more sense (and keep it out of
fs/dcache.c, which is an odd place to have some tty init).

But maybe there's some reason why it's an initcall. Unlikely.

Because it can save data. Each cryptographic algorithm (such as
AES) may have multiple impelmentations, some of which are hardware-
based.

The purpose of these tests are to make a particular driver or
implementation available only if it passes them. So your encrypted
disk/file system will not be subject to a hardware/software combo
without at least some semblance of testing.

The last thing you want to is to upgrade your kernel with a new
hardware crypto driver that detects that you have a piece of rarely-
used crypto hardeware, decides to use it and ends up making your
data toast.

But whatever, if you want the default to be no tests, that's fine.
Here's the patch to do just that.

As requested, this patch sets the default to y and removes the
EMBEDDED dependency.

Umm. The _developer_ had better test the thing. That is absolutely
_zero_ excuse for then forcing every boot for every poor user to re-do
the test over and over again.

Guys, this comes up every single time: you as a developer may think
that your code is really important, but get over yourself already.
It's not so important that everybody must be forced to do it.

Speaking as a user whose been bitten several times by bad crypto
implementations, I'd personally rather have this testing on by default
(if the crypto API it depends on is on). It's pretty damn inexpensive
to do a few brief crypto operations during initialization as a quick
smoke test. We already do something somewhat similar when loading the
RAID5/RAID6 driver, although admittedly that's a speed-test for
picking an optimized algorithm.

You should also realize that crypto drivers are very much *NOT* in the
same situation as most other drivers. Without this test, adding a new
crypto hardware driver to the kernel is a completely unsafe operation,
because it could completely break users setups. You have previously
said you're fine accepting new drivers even after the initial merge
window because they can't break anything, but in crypto that's not
true.

I've actually had it trigger in exactly the described situation. I
had a box with an encrypted filesystem that I downloaded a new distro
kernel on with new drivers. The new kernel included a bunch of new
"EXPERIMENTAL" drivers for hardware, none of which I thought I cared
about until I noticed in "dmesg" that one of them was getting enabled
and then failing tests.

So there are unique and compelling reasons for default-enabled basic
smoke tests of cryptographic support during boot. To be honest, the
test and integration engineer in me would like it if there were more
intensive in-kernel POST tests that could be enabled by a kernel
parameter or something for high-reliability embedded devices.

Cheers,

Maybe Linus would be happier if the self-tests were limited (by
default) to the hardware accelerators? Having a software backup and
the risk of data loss indeed makes things different.

Of course in practice without the tests your boot would probably just
have failed. Badly-decrypted root partitions tend to be noticed as
such long before trying to write to them. Then you would have bitched
on the list and the driver would have been fixed or removed faster
than having to wait for you (or other people with the hardware issue)
to notice the spew in dmesg.

OG.

So you'd rather have a box that doesn't boot rather than one
that automatically falls back to software crypto allowing you
to diagnose and report the problem.

Yes that makes a lot of sense.

What about kernel boot parameter to test hardware accelerators or not?

No. I'd be happier if it was an OPTION.

And it damn well defaults to "off". Like all other options.

Then, for people who use it, and worry (and distro test kernels etc),
turn it on. But don't make it a forced feature, and don't make it
something that people think they _should_ turn on.

I have crypto enabled, but I don't _use_ it. The upside for me is
zero. Nil. Nada. And I bet that's the common case.

And dammit, it you don't trust the hardware, don't send the driver
upstreams. And if you worry about alpha-particles, you should run a
RAM test on every boot. But don't ask _me_ to run one.

It's that simple.
