Subject: Re: [GIT PULL] TPM driver robustness fixes

Hi James,


> These patches don't have proper subjects.

The patch subjects were somehow mangled as it seems.
The original patch subjects were
- char/tpm: Fix uninitialized usage of data buffer
- char/tpm: Call tpm_transmit with correct size
- char/tpm: Zero buffer after copying to userspace

I've sent them to the kernel security list but as it seems during the
transmission to tpmdd the subjects were stripped.
If desired I can resend them.


> Consider what happens in memset if copy_to_user fails.
Sorry I don't see it. Can you please clearify the problem for me?

You're right about that - no discussion happened ;)
