HID: validate HID report id size

2013-09-27T00:18:16+00:00

commit 43622021d2e2b82ea03d883926605bdd0525e1d1 upstream.

The "Report ID" field of a HID report is used to build indexes of
reports. The kernel's index of these is limited to 256 entries, so any
malicious device that sets a Report ID greater than 255 will trigger
memory corruption on the host:

Introduce [compat_]save_altstack_ex() to unbreak x86 SMAP

2013-09-27T00:18:13+00:00

commit bd1c149aa9915b9abb6d83d0f01dfd2ace0680b5 upstream.

For performance reasons, when SMAP is in use, SMAP is left open for an
entire put_user_try { ... } put_user_catch(); block, however, calling
__put_user() in the middle of that block will close SMAP as the
STAC..CLAC constructs intentionally do not nest.

Furthermore, using __put_user() rather than put_user_ex() here is bad
for performance.

Thus, introduce new [compat_]save_altstack_ex() helpers that replace
__[compat_]save_altstack() for x86, being currently the only
architecture which supports put_user_try { ... } put_user_catch().

rculist: list_first_or_null_rcu() should use list_entry_rcu()

2013-09-27T00:18:13+00:00

commit c34ac00caefbe49d40058ae7200bd58725cebb45 upstream.

list_first_or_null() should test whether the list is empty and return
pointer to the first entry if not in a RCU safe manner.  It's broken
in several ways.

* It compares __kernel @__ptr with __rcu @__next triggering the
  following sparse warning.

  net/core/dev.c:4331:17: error: incompatible types in comparison expression (different address spaces)

* It doesn't perform rcu_dereference*() and computes the entry address
  using container_of() directly from the __rcu pointer which is
  inconsitent with other rculist interface.  As a result, all three
  in-kernel users - net/core/dev.c, macvlan, cgroup - are buggy.  They
  dereference the pointer w/o going through read barrier.

* While ->next dereference passes through list_next_rcu(), the
  compiler is still free to fetch ->next more than once and thus
  nullify the "__ptr != __next" condition check.

Fix it by making list_first_or_null_rcu() dereference ->next directly
using ACCESS_ONCE() and then use list_entry_rcu() on it like other
rculist accessors.

v2: Paul pointed out that the compiler may fetch the pointer more than
    once nullifying the condition check.  ACCESS_ONCE() added on
    ->next dereference.

v3: Restored () around macro param which was accidentally removed.
    Spotted by Paul.

USB: fix build error when CONFIG_PM_SLEEP isn't enabled

2013-09-27T00:18:12+00:00

commit 9d8924297cd9c256c23c02abae40202563452453 upstream.

This patch fixes a build error that occurs when CONFIG_PM is enabled
and CONFIG_PM_SLEEP isn't:

>> drivers/usb/host/ohci-pci.c:294:10: error: 'usb_hcd_pci_pm_ops' undeclared here (not in a function)
      .pm = &usb_hcd_pci_pm_ops

Since the usb_hcd_pci_pm_ops structure is defined and used when
CONFIG_PM is enabled, its declaration should not be protected by
CONFIG_PM_SLEEP.

ICMPv6: treat dest unreachable codes 5 and 6 as EACCES, not EPROTO

2013-09-14T13:54:56+00:00

[ Upstream commit 61e76b178dbe7145e8d6afa84bb4ccea71918994 ]

RFC 4443 has defined two additional codes for ICMPv6 type 1 (destination
unreachable) messages:
        5 - Source address failed ingress/egress policy
	6 - Reject route to destination

Now they are treated as protocol error and icmpv6_err_convert() converts them
to EPROTO.

RFC 4443 says:
	"Codes 5 and 6 are more informative subsets of code 1."

Treat codes 5 and 6 as code 1 (EACCES)

Btw, connect() returning -EPROTO confuses firefox, so that fallback to
other/IPv4 addresses does not work:

net_sched: restore "linklayer atm" handling

2013-09-14T13:54:55+00:00

[ Upstream commit 8a8e3d84b1719a56f9151909e80ea6ebc5b8e318 ]

commit 56b765b79 ("htb: improved accuracy at high rates")
broke the "linklayer atm" handling.

 tc class add ... htb rate X ceil Y linklayer atm

The linklayer setting is implemented by modifying the rate table
which is send to the kernel.  No direct parameter were
transferred to the kernel indicating the linklayer setting.

The commit 56b765b79 ("htb: improved accuracy at high rates")
removed the use of the rate table system.

To keep compatible with older iproute2 utils, this patch detects
the linklayer by parsing the rate table.  It also supports future
versions of iproute2 to send this linklayer parameter to the
kernel directly. This is done by using the __reserved field in
struct tc_ratespec, to convey the choosen linklayer option, but
only using the lower 4 bits of this field.

Linklayer detection is limited to speeds below 100Mbit/s, because
at high rates the rtab is gets too inaccurate, so bad that
several fields contain the same values, this resembling the ATM
detect.  Fields even start to contain "0" time to send, e.g. at
1000Mbit/s sending a 96 bytes packet cost "0", thus the rtab have
been more broken than we first realized.

ipv6: drop packets with multiple fragmentation headers

[ Upstream commit f46078cfcd77fa5165bf849f5e568a7ac5fa569c ]

It is not allowed for an ipv6 packet to contain multiple fragmentation
headers. So discard packets which were already reassembled by
fragmentation logic and send back a parameter problem icmp.

The updates for RFC 6980 will come in later, I have to do a bit more
research here.

ip_tunnel: Do not use inner ip-header-id for tunnel ip-header-id.

2013-09-14T13:54:55+00:00

[ Upstream commit 4221f40513233fa8edeef7fc82e44163fde03b9b ]

Using inner-id for tunnel id is not safe in some rare cases.
E.g. packets coming from multiple sources entering same tunnel
can have same id. Therefore on tunnel packet receive we
could have packets from two different stream but with same
source and dst IP with same ip-id which could confuse ip packet
reassembly.

Following patch reverts optimization from commit
490ab08127 (IP_GRE: Fix IP-Identification.)
