This commit adds support for requesting and relinquishing locality 0 in tpm_crb for the course of command transmission. In order to achieve this, two new callbacks are added to struct tpm_class_ops: - request_locality - relinquish_locality With CRB interface you first set either requestAccess or relinquish bit from TPM_LOC_CTRL_x register and then wait for locAssigned and tpmRegValidSts bits to be set in the TPM_LOC_STATE_x register. The reason why were are doing this is to make sure that the driver will work properly with Intel TXT that uses locality 2. There's no explicit guarantee that it would relinquish this locality. In more general sense this commit enables tpm_crb to be a well behaving citizen in a multi locality environment. Signed-off-by:

Currently, there is an unnecessary 1 msec delay added in i2c_nuvoton_write_status() for the successful case. This function is called multiple times during send() and recv(), which implies adding multiple extra delays for every TPM operation. This patch calls usleep_range() only if retry is to be done.

The current code passes the address of tpm_chip as the argument to dev_get_drvdata() without prior NULL check in tpm_ibmvtpm_get_desired_dma. This resulted an oops during kernel boot when vTPM is enabled in Power partition configured in active memory sharing mode. The vio_driver's get_desired_dma() is called before the probe(), which for vtpm is tpm_ibmvtpm_probe, and it's this latter function that initializes the driver and set data. Attempting to get data before the probe() caused the problem. This patch adds a NULL check to the tpm_ibmvtpm_get_desired_dma. fixes: 9e0d39d8 ("tpm: Remove useless priv field in struct tpm_vendor_specific") Cc: <stable@vger.kernel.org> Signed-off-by:

Sessions are different from transient objects in that their handles may not be virtualized (because they're used for some hmac calculations). Additionally when a session is context saved, a vestigial memory remains in the TPM and if it is also flushed, that will be lost and the session context will refuse to load next time, so the code is updated to flush only transient objects after a context save. Add a separate array (chip->session_tbl) to save and restore sessions by handle. Use the failure of a context save or load to signal that the session has been flushed from the TPM and we can remove its memory from chip->session_tbl. Sessions are also isolated during each instance of a tpm space. This means that spaces shouldn't be able to see each other's sessions and is enforced by ensuring that a space user may only refer to sessions handles that are present in their own chip->session_tbl. Finally when a space is closed, all the sessions belonging to it should be flushed so the handles may be re-used by other spaces. Note that if we get a session save or load error, all sessions are effectively flushed. Even though we restore the session buffer, all the old sessions will refuse to load after the flush and they'll be purged from our session memory. This means that while transient context handling is still soft in the face of errors, session handling is hard (any failure of the model means all sessions are lost).

Currently the tpm spaces are not exposed to userspace. Make this exposure via a separate device, which can now be opened multiple times because each read/write transaction goes separately via the space. Concurrency is protected by the chip->tpm_mutex for each read/write transaction separately. The TPM is cleared of all transient objects by the time the mutex is dropped, so there should be no interference between the kernel and userspace. Signed-off-by:

Added an ability to virtualize TPM commands into an isolated context that we call a TPM space because the word context is already heavily used in the TPM specification. Both the handle areas and bodies (where necessary) are virtualized. The mechanism works by adding a new parameter struct tpm_space to the tpm_transmit() function. This new structure contains the list of virtual handles and a buffer of page size (currently) for backing storage. When tpm_transmit() is called with a struct tpm_space instance it will execute the following sequence: 1. Take locks. 2. Load transient objects from the backing storage by using ContextLoad and map virtual handles to physical handles. 3. Perform the transaction. 4. Save transient objects to backing storage by using ContextSave and map resulting physical handle to virtual handle if there is such. This commit does not implement virtualization support for hmac and policy sessions. Signed-off-by:

Check for every TPM 2.0 command that the command code is supported and the command buffer has at least the length that can contain the header and the handle area. For ContextSave and FlushContext we mark the body to be part of the handle area. This gives validation for these commands at zero cost, including the body of the command. The more important reason for this is that we can virtualize these commands in the same way as you would virtualize the handle area of a command. Signed-off-by:

Testing the implementation with a Raspberry Pi 2 showed that under some circumstances its SPI master erroneously releases the CS line before the transfer is complete, i.e. before the end of the last clock. In this case the TPM ignores the transfer and misses for example the GO command. The driver is unable to detect this communication problem and will wait for a command response that is never going to arrive, timing out eventually. As a workaround, the small delay ensures that the CS line is held long enough, even with a faulty SPI master. Other SPI masters are not affected, except for a negligible performance penalty.

This fix enables a platform to enter the idle state (suspend-to-idle) The driver needs to request explicitly go_idle upon completion from the pm suspend handler. The runtime pm is disabled on suspend during prepare state by calling pm_runtime_get_noresume, hence we cannot relay on runtime pm to leave the device in low power state. Symmetrically cmdReady is called upon resume. Signed-off-by:

Commit 500462a9 "timers: Switch to a non-cascading wheel" replaced the 'classic' timer wheel, which aimed for near 'exact' expiry of the timers. Their analysis was that the vast majority of timeout timers are used as safeguards, not as real timers, and are cancelled or rearmed before expiration. The only exception noted to this were networking timers with a small expiry time. Not included in the analysis was the TPM polling timer, which resulted in a longer normal delay and, every so often, a very long delay. The non-cascading wheel delay is based on CONFIG_HZ. For a description of the different rings and their delays, refer to the comments in kernel/time/timer.c. Below are the delays given for rings 0 - 2, which explains the longer "normal" delays and the very, long delays as seen on systems with CONFIG_HZ 250. * HZ 1000 steps * Level Offset Granularity Range * 0 0 1 ms 0 ms - 63 ms * 1 64 8 ms 64 ms - 511 ms * 2 128 64 ms 512 ms - 4095 ms (512ms - ~4s) * HZ 250 * Level Offset Granularity Range * 0 0 4 ms 0 ms - 255 ms * 1 64 32 ms 256 ms - 2047 ms (256ms - ~2s) * 2 128 256 ms 2048 ms - 16383 ms (~2s - ~16s) Below is a comparison of extending the TPM with 1000 measurements, using msleep() vs. usleep_delay() when configured for 1000 hz vs. 250 hz, before and after commit 500462a9. linux-4.7 | msleep() usleep_range() 1000 hz: 0m44.628s | 1m34.497s 29.243s 250 hz: 1m28.510s | 4m49.269s 32.386s linux-4.7 | min-max (msleep) min-max (usleep_range) 1000 hz: 0:017 - 2:760s | 0:015 - 3:967s 0:014 - 0:418s 250 hz: 0:028 - 1:954s | 0:040 - 4:096s 0:016 - 0:816s This patch replaces the msleep() with usleep_range() calls in the i2c nuvoton driver with a consistent max range value.

The expectation is that the if the CRB cmd/rsp buffer falls within the ACPI region that the entire buffer will be within the reason. Otherwise resource reservation will fail when it crosses regions. Work around this BIOS bug by limiting the cmd/rsp buffer to the length of the declared ACPI region. BIOS vendors should fix this by making the ACPI and register length declarations consistent.

TIS v1.3 for TPM 1.2 and PTP for TPM 2.0 disagree about which timeout value applies to reading a valid burstcount. It is TIMEOUT_D according to TIS, but TIMEOUT_A according to PTP, so choose the appropriate value depending on whether we deal with a TPM 1.2 or a TPM 2.0. This is important since according to the PTP TIMEOUT_D is much smaller than TIMEOUT_A. So the previous implementation could run into timeouts with a TPM 2.0, even though the TPM was behaving perfectly fine. During tpm2_probe TIMEOUT_D will be used even with a TPM 2.0, because TPM_CHIP_FLAG_TPM2 is not yet set. This is fine, since the timeout values will only be changed afterwards by tpm_get_timeouts. Until then TIS_TIMEOUT_D_MAX applies, which is large enough. Cc: stable@vger.kernel.org Fixes: aec04cbd ("tpm: TPM 2.0 FIFO Interface") Signed-off-by:

We switched from "struct task_struct"->security to "struct cred"->security in Linux 2.6.29. But not all LSM modules were happy with that change. TOMOYO LSM module is an example which want to use per "struct task_struct" security blob, for TOMOYO's security context is defined based on "struct task_struct" rather than "struct cred". AppArmor LSM module is another example which want to use it, for AppArmor is currently abusing the cred a little bit to store the change_hat and setexeccon info. Although security_task_free() hook was revived in Linux 3.4 because Yama LSM module wanted to release per "struct task_struct" security blob, security_task_alloc() hook and "struct task_struct"->security field were not revived. Nowadays, we are getting proposals of lightweight LSM modules which want to use per "struct task_struct" security blob. We are already allowing multiple concurrent LSM modules (up to one fully armored module which uses "struct cred"->security field or exclusive hooks like security_xfrm_state_pol_flow_match(), plus unlimited number of lightweight modules which do not use "struct cred"->security nor exclusive hooks) as long as they are built into the kernel. But this patch does not implement variable length "struct task_struct"->security field which will become needed when multiple LSM modules want to use "struct task_struct"-> security field. Although it won't be difficult to implement variable length "struct task_struct"->security field, let's think about it after we merged this patch. Signed-off-by:
