* [PATCH 0/6] xfrm_user info leaks
From: Mathias Krause @ 2012-09-19 21:33 UTC (permalink / raw)
To: David S. Miller; +Cc: Steffen Klassert, netdev, linux-kernel, Mathias Krause
Hi David,
the following series fixes various info leaks in the xfrm netlink
interface. As always, a test case can be supplied on request.
Patches 1 to 5 are probably material for stable, too. Patch 6 is just a
minor optimization I stumbled across while auditing the code.
Please apply!
P.S.: What's still missing IMHO, is some upper limit for the ESN replay
window size to prevent malicious users from making the kernel allocate
huge states. One could not retrieve those via netlink anyway (as the
current code allocates just a single page for the state dump). Maybe 4k
is a sane default upper limit for the replay window size. But I'll leave
implementing this to someone else. ;)

copy_to_user_auth() fails to initialize the remainder of alg_name and
therefore discloses up to 54 bytes of heap memory via netlink to
userland.
Use strncpy() instead of strcpy() to fill the trailing bytes of alg_name
with null bytes.

The memory reserved to dump the xfrm policy includes multiple padding
bytes added by the compiler for alignment (padding bytes in struct
xfrm_selector and struct xfrm_userpolicy_info). Add an explicit
memset(0) before filling the buffer to avoid the heap info leak.

The memory used for the template copy is a local stack variable. As
struct xfrm_user_tmpl contains multiple holes added by the compiler for
alignment, not initializing the memory will lead to leaking stack bytes
to userland. Add an explicit memset(0) to avoid the info leak.
Initial version of the patch by Brad Spengler.

* [PATCH 5/6] xfrm_user: ensure user supplied esn replay window is valid
From: Mathias Krause @ 2012-09-19 21:33 UTC (permalink / raw)
To: David S. Miller
Cc: Steffen Klassert, netdev, linux-kernel, Mathias Krause,
Martin Willi
In-Reply-To: <1348090423-32665-1-git-send-email-minipli@googlemail.com>
The current code fails to ensure that the netlink message actually
contains as many bytes as the header indicates. If a user creates a new
state or updates an existing one but does not supply the bytes for the
whole ESN replay window, the kernel copies random heap bytes into the
replay bitmap, the ones happen to follow the XFRMA_REPLAY_ESN_VAL
netlink attribute. This leads to following issues:
1. The replay window has random bits set confusing the replay handling
code later on.
2. A malicious user could use this flaw to leak up to ~3.5kB of heap
memory when she has access to the XFRM netlink interface (requires
CAP_NET_ADMIN).
Known users of the ESN replay window are strongSwan and Steffen's
iproute2 patch (<http://patchwork.ozlabs.org/patch/85962/>). The latter
uses the interface with a bitmap supplied while the former does not.
strongSwan is therefore prone to run into issue 1.
To fix both issues without breaking existing userland allow using the
XFRMA_REPLAY_ESN_VAL netlink attribute with either an empty bitmap or a
fully specified one. For the former case we initialize the in-kernel
bitmap with zero, for the latter we copy the user supplied bitmap.
For state updates the full bitmap must be supplied.

I spent some time trying to track this bug, but found nothing so far.
The timer->function are never cleared by TCP stack at tear down, and
should be set before fd is installed and can be caught by other threads.
Most likely its a refcounting issue...
Following debugging patch might trigger a bug sooner ?

I applied this patch to net-next and tested with e1000e driver.
With iperf I got around 8 % improvement on loopback.

Where does this limit come from? Is that just the standard size netlink
skb?
I'm a little worried that the user-provided
xfrm_replay_state_esn::bmp_len is not being directly validated anywhere.
Currently xfrm_replay_state_esn_len() may overflow, and as its return
type is int it may unexpectedly return a negative value.

I would normally expect to see sizes declared as size_t but mixing
size_t and int in comparisons tends to result in bugs. So I think this
should to be int, matching the return types of nla_len() and
xfrm_replay_state_esn_len() (and apparently all lengths in netlink...)

Also int, for the same reason.

I understand that this is correct since verify_replay() previously
checked that nla_len(rta) is either == sizeof(*up) or >= klen. But
would it not be more obviously correct to test nla_len(rta) >= klen?

Then what would actually trigger creation of the VFs? There's no way we
can assume that some sysfs attribute will be written before the PF
driver is loaded (what if it's built-in?). I thought the idea was to
add a driver callback that would be called when the sysfs attribute was
written.

It opens a window in ucc_geth_start_xmit where the skb slot in
ugeth->tx_skbuff[txQ] is set and T_RA has not been written into
the descriptor status. Consider a racing poll : the !skb test in
ucc_geth_tx may not work as expected.

Ugh, it would mean changing link_up to being done via workqueue.
But your code wasnt safe against changes to values from set_multicast race
either.
