[PATCH v3 1/5] tpm: fix intermittent failure with self tests

by Jarkko Sakkinen

From: James Bottomley <James.Bottomley(a)HansenPartnership.com> My Nuvoton 6xx in a Dell XPS-13 has been intermittently failing to work (necessitating a reboot). The problem seems to be that the TPM gets into a state where the partial self-test doesn't return TPM_RC_SUCCESS (meaning all tests have run to completion), but instead returns TPM_RC_TESTING (meaning some tests are still running in the background). There are various theories that resending the self-test command actually causes the tests to restart and thus triggers more TPM_RC_TESTING returns until the timeout is exceeded. There are several issues here: firstly being we shouldn't slow down the boot sequence waiting for the self test to complete once the TPM backgrounds them. It will actually make available all functions that have passed and if it gets a failure return TPM_RC_FAILURE to every subsequent command. So the fix is to kick off self tests once and if they return TPM_RC_TESTING log that as a backgrounded self test and continue on. In order to prevent other tpm users from seeing any TPM_RC_TESTING returns (which it might if they send a command that needs a TPM subsystem which is still under test), we loop in tpm_transmit_cmd until either a timeout or we don't get a TPM_RC_TESTING return. Finally, there have been observations of strange returns from a partial test. One Nuvoton is occasionally returning TPM_RC_COMMAND_CODE, so treat any unexpected return from a partial self test as an indication we need to run a full self test.

[PATCH v2] clk: mvebu: armada-38x: add support for missing clocks

by Richard Genoud

Clearfog boards can come with a CPU clocked at 1600MHz (commercial) or 1333MHz (industrial). They have also some dip-switches to select a different clock (666, 800, 1066, 1200). The funny thing is that the recovery button is on the MPP34 fq selector. So, when booting an industrial board with this button down, the frequency 666MHz is selected (and the kernel didn't boot). This patch add all the missing clocks. The only mode I didn't test is 2GHz (uboot found 4294MHz instead :/ ).

[PATCH] tpm_tis: fix potential buffer overruns caused by bit glitches on the bus

by Jarkko Sakkinen

From: Jeremy Boone <jeremy.boone(a)nccgroup.trust> commit 2c0a646268f2a3536866bf237733a52aec260594 upstream Discrete TPMs are often connected over slow serial buses which, on some platforms, can have glitches causing bit flips. In all the driver _recv() functions, we need to use a u32 to unmarshal the response size, otherwise a bit flip of the 31st bit would cause the expected variable to go negative, which would then try to read a huge amount of data. Also sanity check that the expected amount of data is large enough for the TPM header.

[PATCH 4.9 0/2] Clear LED_BLINK_SW flag in led_blink_set()

by Jacek Anaszewski

The fix for brightness setting when setting delay_off=0 introduces a regression and has truncated commit message. Revert that patch and apply the one-line change required to fix the original issue in the way appropriate for the 4.9 code base.
