Just to clarify .. that's true of the dcache stuff.
The strscpy case actually explicitly limits things to page boundaries
and falls back to the byte-by-byte case after that.

When checking whether the response is large enough to be able to contain
the received random bytes in tpm_get_random() and tpm2_get_random(),
they fail to take account the header size, which should be added to the

As usual, the rc2 release is pretty small. People are taking a
breather after the merge window, and it takes a bit of time for bug
reports to start coming in and get identified. Plus people were
probably still on vacation (particularly Europe), and some people were
at Open Source Summit NA last we

I'll take a final look at V3, once you have tidied up the
various review comments, but this looks nearly ready to
merge to me.
Thanks,

When page-table entries are set, the compiler might optimize their
assignment by using multiple instructions to set the PTE. This might
turn into a security hazard if the user somehow manages to use the

Provide a function for copying init_mm. This function will be later used
for setting a temporary mm.

This patch-set addresses some issues that were raised in a recent
correspondence and might affect the security and the correctness of code
patching. (Note that patching performance is not addressed by this
patch-set).
The main issue that the patches deal with is the fact that the fixmap

text_mutex is expected to be held before text_poke() is called, but we
cannot add a lockdep assertion since kgdb does not take it, and instead
*supposedly* ensures the lock is not taken and will not be acquired by
any other core while text_poke() is running.
The reason for the "supposedly" comment
From: Andy Lutomirski
Sometimes we want to set a temporary page-table entries (PTEs) in one of
the cores, without allowing other cores to use - even speculatively -
these mappings. There are two benefits for doing so:
(1) Security: if sensitive PTEs are set, temporary mm prevents their use
in ot
The return value of text_poke() is meaningless - it is one of the
function inputs. One day someone may allow the callers to deal with
text_poke() failures, if those actually happen.
In the meanwhile, remove the return value.

text_poke() can potentially compromise the security as it sets temporary
PTEs in the fixmap. These PTEs might be used to rewrite the kernel code
from other cores accidentally or maliciously, if an attacker gains the
ability to write onto kernel memory.
Moreover, since remote TLBs are not flushed a
To prevent improper use of the PTEs that are used for text patching, we
want to use a temporary mm struct. We initailize it by copying the init
mm.
The address that will be used for patching is taken from the lower area
that is usually used for the task memory. Doing so prevents the need to
