Subject: [PATCH v11 0/3] tpm: robust stack allocations
Date: Tue, 23 Sep 2025 20:07:41 +0300	[thread overview]
Message-ID: <20250923170744.1749132-1-jarkko@kernel.org> (raw)

1. These are previous changes to tpm_buf, which make stack allocations
   much more feasible than previously.
2. Migrate low-hanging fruit to use stack allocations.
3. Re-orchestrate tpm_get_random().

Jarkko Sakkinen (3):
  tpm: Make TPM buffer allocations more robust
  tpm: Use TPM_MIN_BUF_SIZE in driver commands
  tpm orchestrate tpm_get_random() in the function
