[PATCH 01/10] tpm, tpm_crb: fix unaligned read of the command buffer address

[Jarkko Sakkinen]

The command buffer address must be read with exactly two 32-bit reads.
Otherwise, on some HW platforms, it seems that HW will abort the read
operation, which causes CPU to fill the read bytes with 1's. Therefore,
we cannot rely on memcpy_fromio() but must call ioread32() two times
instead.

Also, this matches the PC Client Platform TPM Profile specification,
which defines command buffer address with two 32-bit fields.

The canonical form would be

?
Or am I missing something?
Shall I fix-up?

Thanks,

Please do. Current works but definitely your form is correct.

[PATCH 02/10] tpm, tpm_tis: fix tpm_tis ACPI detection issue with TPM 2.0

[Jarkko Sakkinen]

Both for FIFO and CRB interface TCG has decided to use the same HID
MSFT0101. They can be differentiated by looking at the start method from
TPM2 ACPI table. This patches makes necessary fixes to tpm_tis and
tpm_crb modules in order to correctly detect, which module should be
used.

For MSFT0101 we must use struct acpi_driver because struct pnp_driver
has a 7 character limitation.

It turned out that the root cause in b371616b8 was not correct for
https://bugzilla.kernel.org/show_bug.cgi?id=98181.

v2:

* One fixup was missing from v1: is_tpm2_fifo -> is_fifo

v3:

* Use pnp_driver for existing HIDs and acpi_driver only for MSFT0101 in
  order ensure backwards compatibility.

v4:

* Check for FIFO before doing *anything* in crb_acpi_add().
* There was return immediately after acpi_bus_unregister_driver() in
  cleanup_tis(). This caused pnp_unregister_driver() not to be called.

[PATCH 03/10] sysfs: added __compat_only_sysfs_link_entry_to_kobj()

[Jarkko Sakkinen]

Added a new function __compat_only_sysfs_link_group_to_kobj() that adds
a symlink from attribute or group to a kobject. This needed for
maintaining backwards compatibility with PPI attributes in the TPM
driver.

I think everyone was otherwise OK with this with only one contradiction
as I read previous dicussions about this patch:

- This name was propsed by Tejun Heo
- Greg doubted whether it is a good name.

We can fixup to another name if someone says what it would be.

One problem with this patch is that it adds a bunch of code but none of
it is used.  So if there is a bug, git bisect will point to a later
patch instead of this one.

It is fairly standard practice to split cross-subsystem patches like
this, it aids review. git bisect is not a perfect tool.

On an Acer C720 this call to kernfs_find_and_get fails resulting in
a failed resume after suspend.

Apparently it can't find an object for the name "ppi".

This bug does not appear until the next patch is applied which
calls __compat_only_sysfs_link_entry_to_kobj.

I think I might have found something thanks to your help

First I found this old bug:

https://bugzilla.redhat.com/show_bug.cgi?id=1096511

What is happening is that DSM is not found and therefore tpm_add_ppi()
does not add ppi to sysfs groups array.

__compat_only_sysfs_link_entry_to_kobj() is called after tpm_add_ppi
unconditionally for TPM1.

I'll implement a fix for this ASAP.

Thank you for great effort on finding tis!

I pushed a fix over here:

https://github.com/jsakkine/linux-tpmdd/tree/fixes

I'm at the moment in process testing it. Can you run 'acpidump' on your
laptop and send the output me in private? I'll just verify that my
deduction for the root cause is correct.

This fix does work since it effectively avoids the call to
__compat_only_sysfs_link_entry_to_kobj().

Have you tested cases where __compat_only_sysfs_link_entry_to_kobj()
is actually used?

Yes, of course I have. And I checked your DSDT and my assumption was
correct. There was no DSM in the ACPI object.

However, there is probably another regression but it is caused by some
patch that was added earlier. I strongly believe it is not caused by any
of my 4.4 patches.

I think what was happening with you was that
__compat_only_sysfs_link_entry_to_kobj() was returning -ENOENT, which it
should do when target is not found. This was propagated to tpm_tis and
it probably messes up clean up somehow.

I have to test my hypothesis as soon as possible. The fix that I pushed
is still valid no matter which way the things are.

Turns out that after all the second issue that I described was also
because of this patch.

Clean up was not done properly when that function. I revised my fix.

If you want to help, check that the revised patch works I'll add
Tested-by to the patch. Thank you!

I tested the patch (link below) and it works with one small caveat.
The patch would not apply because line 231 uses list_add_tail_rcu
instead of list_add_rcu.  I am working from commit 9b774d5cf2d where
the problem started.  Your repo likely has other changes involved.

Yes, that branch also fix that changes one list_add_rcu() to
list_add_tail_rcu(). I'll add Tested-by to the commit message. Thanks

[PATCH 04/10] tpm: move the PPI attributes to character device directory.

[Jarkko Sakkinen]

Moved PPI attributes to the character device directory. This aligns with
the sysfs guidelines and makes them race free because they are created
atomically with the character device as part of device_register().The
character device and the sysfs attributes appear at the same time to the
user space.

As part of this change we enable PPI attributes also for TPM 2.0
devices. In order to retain backwards compatibility with TPM 1.x
devices, a symlink is created to the platform device directory.

The commit for this patch (9b774d5cf2db4) present in the latest
linux-next (20151101+) breaks suspend/resume on an Acer C720 Chromebook.
The computer will successfully suspend but when a resume is attempted
a blank screen is displayed for a few seconds and then it reboots.

Are you able to acquire kernel logs?

Yup, it's C720P!

Both of these questions still apply. Even if I create the same
environment, your logs might have something useful embedded.

Thank you for reporting this issue! I'll try to find a way to reproduce
and fix it at latest for -rc2.

I have attached the full dmesg.  The following snippets looked
particularly interesting.

  ...

Notice the "tpm_tis: probe of ... failed with error".  With a working
kernel this probe succeeds.  However, the probe fails, which causes it
to try unload the module which produces the "free already-free IRQ"
trace.  The IRQ message is a secondary issue.  Interrupts were disabled
due to a firmware bug and it is trying to free them anyway.

  ...
  [    2.244779] tpm_tis 00:08: [Firmware Bug]: TPM interrupt not working, polling instead
  ...

So the patch changed something which causes the probe to fail.  I
haven't figured out what that is yet.

[PATCH 06/10] tpm: introduce tpm_buf

[Jarkko Sakkinen]

This patch introduces struct tpm_buf that provides a string buffer for
constructing TPM commands. This allows to construct variable sized TPM
commands. For the buffer a page is allocated and mapped, which limits
maximum size to PAGE_SIZE.

Variable sized TPM commands are needed in order to add algorithmic
agility.

Does it matter? Message is emitted only once since it does not sense to
even try to add new data if overflow flag has been set. I.e. even if I
had WARN_ONCE there I still would have the check for overflow flag
before this.

[PATCH 08/10] tpm: seal/unseal for TPM 2.0

[Jarkko Sakkinen]

Added tpm_trusted_seal() and tpm_trusted_unseal() API for sealing
trusted keys.

This patch implements basic sealing and unsealing functionality for
TPM 2.0:

* Seal with a parent key using a 20 byte auth value.
* Unseal with a parent key using a 20 byte auth value.

This patch adds a lot of code but doesn't use any of it until later
patches.  This can make using 'git bisect' more difficult because it
will point to the wrong patches.  If this were my patch series I would
combine this patch with the later ones that actually start using the
code.

I do agree with you that it'd had been a good idea. Thanks for the

[PATCH 09/10] keys, trusted: seal/unseal with TPM 2.0 chips

[Jarkko Sakkinen]

Call tpm_seal_trusted() and tpm_unseal_trusted() for TPM 2.0 chips.
We require explicit 'keyhandle=' option because there's no a fixed
storage root key inside TPM2 chips.

[PATCH 10/10] MAINTAINERS: add new maintainer for TPM DEVICE DRIVER

[Jarkko Sakkinen]

At the moment, no one has time to pay enough attention to this subsystem
so that patches get eventually merged into linux-next. Even critical bug
fixes can lie for weeks.

I'm happy to continue with the current maintainers if they are able to
do their job but if this is not the case I cannot find any other
solution but apply myself for the job.

If there is someone more experienced and/or competent, I'm also happy
to let one take the stand. Anything works as long as it works. I just
want a solution for this bottleneck.
