Hi James,


The following changes since commit 2e270d84223262a38d4755c61d55f5c73ea89e56:

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6 (2011-03-16 13:26:17 -0700)

are available in the git repository at:

Peter Huewe (3):

This patch changes the call of tpm_transmit by supplying the size of the userspace buffer instead of TPM_BUFSIZE

This patch fixes information leakage to the userspace by initializing the data buffer to zero

Since the buffer might contain security related data it might be a good idea to zero the buffer after we have copied it to userspace.

Given the nature of these changes, they should go to current linus as bug fixes.

Thanks,
Rajiv
