2020-03-11ipmi_si: Avoid spurious errors for optional IRQsTakashi Iwai1-2/+2
Although the IRQ assignment in ipmi_si driver is optional, platform_get_irq() spews error messages unnecessarily: ipmi_si dmi-ipmi-si.0: IRQ index 0 not found Fix this by switching to platform_get_irq_optional().

2020-02-17tpm: Initialize crypto_id of allocated_banks to HASH_ALGO__LASTRoberto Sassu1-0/+2
chip->allocated_banks, an array of tpm_bank_info structures, contains the list of TPM algorithm IDs of allocated PCR banks. It also contains the corresponding ID of the crypto subsystem, so that users of the TPM driver can calculate a digest for a PCR extend operation. However, if there is no mapping between TPM algorithm ID and crypto ID, the crypto_id field of tpm_bank_info remains set to zero (the array is allocated and initialized with kcalloc() in tpm2_get_pcr_allocation()). Zero should not be used as value for unknown mappings, as it is a valid crypto ID (HASH_ALGO_MD4). Thus, initialize crypto_id to HASH_ALGO__LAST.

Revert tpm_tis_spi_mod.ko back to tpm_tis_spi.ko as the rename could break user space scripts. This can be achieved by renaming tpm_tis_spi.c as tpm_tis_spi_main.c. Then tpm_tis_spi-y can be used inside the makefile.

2020-01-30char: hpet: Fix out-of-bounds read bugGustavo A. R. Silva1-1/+1
Currently, there is an out-of-bounds read on array hpetp->hp_dev in the following for loop: 870 for (i = 0; i < hdp->hd_nirqs; i++) 871 hpetp->hp_dev[i].hd_hdwirq = hdp->hd_irq[i]; This is due to the recent change from one-element array to flexible-array member in struct hpets: 104 struct hpets { ... 113 struct hpet_dev hp_dev[]; 114 }; This change affected the total size of the dynamic memory allocation, decreasing it by one time the size of struct hpet_dev.

2020-01-23char: hpet: Use flexible-array memberGustavo A. R. Silva1-1/+1
Old code in the kernel uses 1-byte and 0-byte arrays to indicate the presence of a "variable length array": struct something { int length; u8 data[1]; }; struct something *instance; instance = kmalloc(sizeof(*instance) + size, GFP_KERNEL); instance->length = size; memcpy(instance->data, source, size); There is also 0-byte arrays. Both cases pose confusion for things like sizeof(), CONFIG_FORTIFY_SOURCE, etc.[1] Instead, the preferred mechanism to declare variable-length types such as the one above is a flexible array member[2] which need to be the last member of a structure and empty-sized: struct something { int stuff; u8 data[]; }; Also, by making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being unadvertenly introduced[3] to the codebase from now on.

2020-01-07random: ignore GRND_RANDOM in getentropy(2)Andy Lutomirski1-3/+0
The separate blocking pool is going away. Start by ignoring GRND_RANDOM in getentropy(2). This should not materially break any API. Any code that worked without this change should work at least as well with this change.

2020-01-07random: Add a urandom_read_nowait() for random APIs that don't warnAndy Lutomirski1-6/+15
/dev/random and getrandom() never warn. Split the meat of urandom_read() into urandom_read_nowarn() and leave the warning code in urandom_read(). This has no effect on kernel behavior, but it makes subsequent patches more straightforward. It also makes the fact that getrandom() never warns more obvious.

2020-01-07char/random: silence a lockdep splat with printk()Sergey Senozhatsky1-2/+3
Sergey didn't like the locking order, uart_port->lock -> tty_port->lock uart_write (uart_port->lock) __uart_start pl011_start_tx pl011_tx_chars uart_write_wakeup tty_port_tty_wakeup tty_port_default tty_port_tty_get (tty_port->lock) but those code is so old, and I have no clue how to de-couple it after checking other locks in the splat.

There has been a bunch of reports (one from kernel bugzilla linked) reporting that when this commit is applied it causes on some machines boot freezes. Unfortunately hardware where this commit causes a failure is not widely available (only one I'm aware is Lenovo T490), which means we cannot predict yet how long it will take to properly fix tpm_tis interrupt probing. Thus, the least worst short term action is to revert the code to the state before this commit.

When an application sends TPM commands in NONBLOCKING mode the driver holds chip->tpm_mutex returning from write(), which triggers: "WARNING: lock held when returning to user space". To fix this issue the driver needs to release the mutex before returning and acquire it again in tpm_dev_async_work() before sending the command.

2019-12-17security: keys: trusted: fix lost handle flushJames Bottomley2-1/+1
The original code, before it was moved into security/keys/trusted-keys had a flush after the blob unseal. Without that flush, the volatile handles increase in the TPM until it becomes unusable and the system either has to be rebooted or the TPM volatile area manually flushed. Fix by adding back the lost flush, which we now have to export because of the relocation of the trusted key code may cause the consumer to be modular.

2019-12-11drivers: ipmi: Support raw i2c packet in IPMBVijay Khemka1-0/+29
Many IPMB devices don't support smbus protocol and this driver only supports the smbus protocol at the moment. Added support for the i2c protocol as well. There will be a variable "i2c-protocol" passed by the device tree or ACPI table which determines whether the protocol is i2c or smbus.
