2019-08-05tpm: tpm_ibm_vtpm: Fix unallocated banksNayna Jain4-17/+47
The nr_allocated_banks and allocated banks are initialized as part of tpm_chip_register. Currently, this is done as part of auto startup function. However, some drivers, like the ibm vtpm driver, do not run auto startup during initialization. This results in uninitialized memory issue and causes a kernel panic during boot. This patch moves the pcr allocation outside the auto startup function into tpm_chip_register. This ensures that allocated banks are initialized in any case.

Pull tpm updates from Jarkko Sakkinen: "This contains two critical bug fixes and support for obtaining TPM events triggered by ExitBootServices(). For the latter I have to give a quite verbose explanation not least because I had to revisit all the details myself to remember what was going on in Matthew's patches. The preboot software stack maintains an event log that gets entries every time something gets hashed to any of the PCR registers. What gets hashed could be a component to be run or perhaps log of some actions taken just to give couple of coarse examples. In general, anything relevant for the boot process that the preboot software does gets hashed and a log entry with a specific event type [1]. The main application for this is remote attestation and the reason why it is useful is nicely put in the very first section of [1]: "Attestation is used to provide information about the platform’s state to a challenger. However, PCR contents are difficult to interpret; therefore, attestation is typically more useful when the PCR contents are accompanied by a measurement log. While not trusted on their own, the measurement log contains a richer set of information than do the PCR contents. The PCR contents are used to provide the validation of the measurement log." Because EFI_TCG2_PROTOCOL.GetEventLog() is not available after calling ExitBootServices(), Linux EFI stub copies the event log to a custom configuration table. Unfortunately, ExitBootServices() also generates events and obviously these events do not get copied to that table. Luckily firmware does this for us by providing a configuration table identified by EFI_TCG2_FINAL_EVENTS_TABLE_GUID. This essentially contains necessary changes to provide the full event log for the use the user space that is concatenated from these two partial event logs [2]" [1] https://trustedcomputinggroup.org/resource/pc-client-specific-platform-firmware-profile-specification/ [2] The final concatenation is done in drivers/char/tpm/eventlog/efi.c * tag 'tpmdd-next-20190625' of git://git.infradead.org/users/jjs/linux-tpmdd: tpm: Don't duplicate events from the final event log in the TCG2 log Abstract out support for locating an EFI config table tpm: Fix TPM 1.2 Shutdown sequence to prevent future TPM operations efi: Attempt to get the TCG2 event log in the boot stub tpm: Append the final event log to the TPM event log tpm: Reserve the TPM final events table tpm: Abstract crypto agile event size calculations tpm: Actually fail on TPM errors during "get random"

2019-06-24tpm: Don't duplicate events from the final event log in the TCG2 logMatthew Garrett1-1/+10
After the first call to GetEventLog() on UEFI systems using the TCG2 crypto agile log format, any further log events (other than those triggered by ExitBootServices()) will be logged in both the main log and also in the Final Events Log. While the kernel only calls GetEventLog() immediately before ExitBootServices(), we can't control whether earlier parts of the boot process have done so. This will result in log entries that exist in both logs, and so the current approach of simply appending the Final Event Log to the main log will result in events being duplicated. We can avoid this problem by looking at the size of the Final Event Log just before we call ExitBootServices() and exporting this to the main kernel. The kernel can then skip over all events that occured before ExitBootServices() and only append events that were not also logged to the main log.

Any events that are logged after GetEventsLog() is called are logged to the EFI Final Events table. These events are defined as being in the crypto agile log format, so we can just append them directly to the existing log if it's in the same format. In theory we can also construct old-style SHA1 log entries for devices that only return logs in that format, but EDK2 doesn't generate the final event log in that case so it doesn't seem worth it at the moment.

2019-06-24tpm: Reserve the TPM final events tableMatthew Garrett1-1/+1
UEFI systems provide a boot services protocol for obtaining the TPM event log, but this is unusable after ExitBootServices() is called. Unfortunately ExitBootServices() itself triggers additional TPM events that then can't be obtained using this protocol. The platform provides a mechanism for the OS to obtain these events by recording them to a separate UEFI configuration table which the OS can then map. Unfortunately this table isn't self describing in terms of providing its length, so we need to parse the events inside it to figure out how long it is. Since the table isn't mapped at this point, we need to extend the length calculation function to be able to map the event as it goes along.

2019-06-24driver_find_device: Unify the match function with class_find_device()Suzuki K Poulose1-4/+4
The driver_find_device() accepts a match function pointer to filter the devices for lookup, similar to bus/class_find_device(). However, there is a minor difference in the prototype for the match parameter for driver_find_device() with the now unified version accepted by {bus/class}_find_device(), where it doesn't accept a "const" qualifier for the data argument. This prevents us from reusing the generic match functions for driver_find_device(). For this reason, change the prototype of the driver_find_device() to make the "match" parameter in line with {bus/class}_find_device() and adjust its callers to use the const qualifier. Also, we could now promote the "data" parameter to const as we pass it down as a const parameter to the match functions.

2019-06-24bus_find_device: Unify the match callback with class_find_deviceSuzuki K Poulose1-1/+1
There is an arbitrary difference between the prototypes of bus_find_device() and class_find_device() preventing their callers from passing the same pair of data and match() arguments to both of them, which is the const qualifier used in the prototype of class_find_device(). If that qualifier is also used in the bus_find_device() prototype, it will be possible to pass the same match() callback function to both bus_find_device() and class_find_device(), which will allow some optimizations to be made in order to avoid code duplication going forward. Also with that, constify the "data" parameter as it is passed as a const to the match function. For this reason, change the prototype of bus_find_device() to match the prototype of class_find_device() and adjust its callers to use the const qualifier in accordance with the new prototype of it.

2019-06-19ipmi: ipmb: don't allocate i2c_client on stackArnd Bergmann1-10/+11
The i2c_client structure can be fairly large, which leads to a warning about possible kernel stack overflow in some configurations: drivers/char/ipmi/ipmb_dev_int.c:115:16: error: stack frame size of 1032 bytes in function 'ipmb_write' [-Werror,-Wframe-larger-than=] There is no real reason to even declare an i2c_client, as we can simply call i2c_smbus_xfer() directly instead of the i2c_smbus_write_block_data() wrapper. Convert the ipmb_write() to use an open-coded i2c_smbus_write_block_data() here, without changing the behavior. It seems that there is another problem with this implementation; when user space passes a length of more than I2C_SMBUS_BLOCK_MAX bytes, all the rest is silently ignored. This should probably be addressed in a separate patch, but I don't know what the intended behavior is here.
