Hi Linus sorry for this unusual procedure of me requesting a patch to be pulled. I asked for several months the maintainers (David: asymmetric keys, Jarkko: key subsystem) to pick my patch but without any luck. I signed the tag, but probably it would not matter, since my key is not among your trusted keys. The following changes since commit 921bdc72a0d68977092d6a64855a1b8967acc1d9: Merge tag 'mmc-v6.4-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc (2023-06-02 08:35:13 -0400) are available in the Git repository at: https://github.com/robertosassu/linux.git tags/asym-keys-fix-for-linus-v6.4-rc5 for you to fetch changes up to c3d03e8e35e005e1a614e51bb59053eeb5857f76: KEYS: asymmetric: Copy sig and digest in public_key_verify_signature() (2023-06-02 15:36:23 +0200) ---------------------------------------------------------------- Asymmetric keys fix for v6.4-rc5 Here is a small fix to make an unconditional copy of the buffer passed to crypto operations, to take into account the case of the stack not in the linear mapping area. It has been tested and verified to fix the bug.
