Subject: [PATCH v10 0/4] tpm: robust stack allocations
Date: Sun, 21 Sep 2025 05:08:00 +0300	[thread overview]
Message-ID: <20250921020804.1088824-1-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.

Jarkko Sakkinen (4):
  tpm: Make TPM buffer allocations more robust
  tpm, tpm1-cmd: Use stack for trivial cases
  tpm, tpm2-cmd: Use stack for trivial cases
  tpm_vpm_proxy: Use stack for TPM_CC_SET_LOCALITY
