tpm_tis: Do not flush uninitialized work

2024-06-04T22:18:01Z

tpm_tis_core_init() may fail before tpm_tis_probe_irq_single() is called, in which case tpm_tis_remove() unconditionally calling flush_work() is triggering a warning for .func still being NULL.

tpm: Enable TCG_TPM2_HMAC by default only for X86_64

2024-05-28T10:14:29Z

Given the not fully root caused performance issues on non-x86 platforms, enable the feature by default only for x86-64. That is the platform it brings the most value and has gone most of the QA. Can be reconsidered later and can be obviously opt-in enabled too on any arch.

tpm: Rename TPM2_OA_TMPL to TPM2_OA_NULL_KEY and make it local

2024-05-28T10:14:23Z

Rename and document TPM2_OA_TMPL, as originally requested in the patch set review, but left unaddressed without any appropriate reasoning. The new name is TPM2_OA_NULL_KEY, has a documentation and is local only to tpm2-sessions.c.

With only single call site, this makes no sense (slipped out of the radar during the review). Open code and document the action directly to the site, to make it more readable. Fixes: 1b6d7f9eb150 ("tpm: add session encryption protection to tpm2_get_random()") Signed-off-by: Jarkko Sakkinen

tpm_tis_spi: Account for SPI header when allocating TPM SPI xfer buffer

2024-05-28T10:03:57Z

The TPM SPI transfer mechanism uses MAX_SPI_FRAMESIZE for computing the maximum transfer length and the size of the transfer buffer. As such, it does not account for the 4 bytes of header that prepends the SPI data frame. This can result in out-of-bounds accesses and was confirmed with KASAN. Introduce SPI_HDRSIZE to account for the header and use to allocate the transfer buffer. Fixes: a86a42ac2bd6 ("tpm_tis_spi: Add hardware wait polling") Signed-off-by: Matthew R.

hwrng: core - Remove add_early_randomness

2024-05-26T10:32:16Z

A potential deadlock was reported with the config file at https://web.archive.org/web/20240522052129/https://0x0.st/XPN_.txt In this particular configuration, the deadlock doesn't exist because the warning triggered at a point before modules were even available. However, the deadlock can be real because any module loaded would invoke async_synchronize_full. The issue is spurious for software crypto algorithms which aren't themselves involved in async probing. However, it would be hard to avoid for a PCI crypto driver using async probing. In this particular call trace, the problem is easily avoided because the only reason the module is being requested during probing is the add_early_randomness call in the hwrng core. This feature is vestigial since there is now a kernel thread dedicated to doing exactly this. So remove add_early_randomness as it is no longer needed. Reported-by: Nícolas F. R. A.
