commit a203c2aa4cefccb879c879b8e1cad1a09a679e55 upstream.
At the beginning of wiphy_update_regulatory() a check is performed
whether the request is to be ignored. Then the request is sent to
the driver nevertheless. This happens even if last_request points
to NULL, leading to a crash in the driver:

Fix this by returning early. Also remove the out: label as it is
not any longer needed.

commit ebc63e531cc6a457595dd110b07ac530eae788c3 upstream.
After commit 3262c816a3d7fb1eaabce633caa317887ed549ae "[PATCH] knfsd:
split svc_serv into pools", svc_delete_xprt (then svc_delete_socket) no
longer removed its xpt_ready (then sk_ready) field from whatever list it
was on, noting that there was no point since the whole list was about to
be destroyed anyway.
That was mostly true, but forgot that a few svc_xprt_enqueue()'s might
still be hanging around playing with the about-to-be-destroyed list, and
could get themselves into trouble writing to freed memory if we left
this xprt on the list after freeing it.
(This is actually functionally identical to a patch made first by Ben
Greear, but with more comments.)

commit 67ae7cf1eeda777f79259c4c6cb17a0bd28dee71 upstream.
Some drivers (ab)use the ethtool_ops::get_regs operation to expose
only a hardware revision ID. Commit
a77f5db361ed9953b5b749353ea2c7fed2bf8d93 ('ethtool: Allocate register
dump buffer with vmalloc()') had the side-effect of breaking these, as
vmalloc() returns a null pointer for size=0 whereas kmalloc() did not.
For backward-compatibility, allow zero-length dumps again.

commit 0c03150e7ea8f7fcd03cfef29385e0010b22ee92 upstream.
A bridge topology with three systems:
+------+ +------+
| A(2) |--| B(1) |
+------+ +------+
\ /
+------+
| C(3) |
+------+
What is supposed to happen:
* bridge with the lowest ID is elected root (for example: B)
* C detects that A->C is higher cost path and puts in blocking state
What happens. Bridge with lowest id (B) is elected correctly as
root and things start out fine initially. But then config BPDU
doesn't get transmitted from A -> C. Because of that
the link from A-C is transistioned to the forwarding state.
The root cause of this is that the configuration messages
is generated with bogus message age, and dropped before
sending.
In the standardmessage_age is supposed to be:
the time since the generation of the Configuration BPDU by
the Root that instigated the generation of this Configuration BPDU.
Reimplement this by recording the timestamp (age + jiffies) when
recording config information. The old code incorrectly used the time
elapsed on the ageing timer which was incorrect.

Update the code to handle some of the differences between
RFC 3041 and RFC 4941, which obsoletes it. Also a couple
of janitorial fixes.
- Allow router advertisements to increase the lifetime of
temporary addresses. This was not allowed by RFC 3041,
but is specified by RFC 4941. It is useful when RA
lifetimes are lower than TEMP_{VALID,PREFERRED}_LIFETIME:
in this case, the previous code would delete or deprecate
addresses prematurely.
- Change the default of MAX_RETRY to 3 per RFC 4941.
- Add a comment to clarify that the preferred and valid
lifetimes in inet6_ifaddr are relative to the timestamp.
- Shorten lines to 80 characters in a couple of places.

Removed superfluous event handling which was used to signal
that the rfcomm kthread had been woken. This appears to have been
used to prevent lost wakeups. Correctly ordering when the task
state is set to TASK_INTERRUPTIBLE is sufficient to prevent lost wakeups.
To prevent wakeups which occurred prior to initially setting
TASK_INTERRUPTIBLE from being lost, the main work of the thread loop -
rfcomm_process_sessions() - is performed prior to sleeping.

This was triggered by turning off encryption on ACL link when rfcomm
was using high security. rfcomm_security_cfm (which is called from rx
task) was closing DLC and this involves sending disconnect message
(and locking socket).
Move closing DLC to rfcomm_process_dlcs and only flag DLC for closure
in rfcomm_security_cfm.

* uid handling
- Limit UID impersonation to processes with a gid in AID_NET_BW_ACCT.
This affects socket tagging, and data removal.
- Limit stats lookup to own uid or the process gid is in AID_NET_BW_STATS.
This affects stats lookup.
* allow pacifying the module
Setting passive to Y/y will make the module return immediately on
external stimulus.
No more stats and silent success on ctrl writes.
Mainly used when one suspects this module of misbehaving.

* Add a new ctrl command to delete stored data.
d <acct_tag> [<uid>]
The uid will default to the running process's.
The accounting tag can be 0, in which case all counters and socket tags
associated with the uid will be cleared.
* Simplify the ctrl command handling at the expense of duplicate code.
This should make it easier to maintain.
* /proc/net/xt_qtaguid/stats now returns more stats
idx iface acct_tag_hex uid_tag_int
{rx,tx}_{bytes,packets}
{rx,tx}_{tcp,udp,other}_{bytes,packets}
the {rx,tx}_{bytes,packets} are the totals.

This uses the NETLINK NETLINK_NFLOG family to log a single message
when the quota limit is reached.
It uses the same packet type as ipt_ULOG, but
- never copies skb data,
- uses 112 as the event number (ULOG's +1)
It doesn't log if the module param "event_num" is 0.

open(2) must always include one of O_RDONLY, O_WRONLY, or O_RDWR. No need
for any O_APPEND special case.
Passing O_WRONLY|O_RDWR is undefined according to the man page, but the
Linux VFS interprets this as O_RDWR, so we'll do the same.
This fixes open(2) with flags O_RDWR|O_APPEND, which was incorrectly being
translated to readonly.

Partial revert of commit aabf6f89. When the hidp session thread
was converted from kernel_thread to kthread, the atomic/wakeups
were replaced with kthread_stop. kthread_stop has blocking semantics
which are inappropriate for the hidp session kthread. In addition,
the kthread signals itself to terminate in hidp_process_hid_control()
- it cannot do this with kthread_stop().
Lastly, a wakeup can be lost if the wakeup happens between checking
for the loop exit condition and setting the current state to
TASK_INTERRUPTIBLE. (Without appropriate synchronization mechanisms,
the task state should not be changed between the condition test and
the yield - via schedule() - as this creates a race between the
wakeup and resetting the state back to interruptible.)

A remote user can provide a small value for the command size field in
the command header of an l2cap configuration request, resulting in an
integer underflow when subtracting the size of the configuration request
header. This results in copying a very large amount of data via

There is no software fallback implemented for SCTP or FCoE checksumming,
and so it should not be passed on by software devices like bridge or bonding.
For VLAN devices, this is different. First, the driver for underlying device
should be prepared to get offloaded packets even when the feature is disabled
(especially if it advertises it in vlan_features). Second, devices under
VLANs do not get replaced without tearing down the VLAN first.
This fixes a mess I accidentally introduced while converting bonding to
ndo_fix_features.
NETIF_F_SOFT_FEATURES are removed from BOND_VLAN_FEATURES because they
are unused as of commit 712ae51afd.

Packets to devices without NETIF_F_SCTP_CSUM (including NETIF_F_NO_CSUM)
should be properly checksummed because the packets can be diverted or
rerouted after construction. This still leaves packets diverted from
NETIF_F_SCTP_CSUM-enabled devices with broken checksums. Fixing this
needs implementing software offload fallback in networking core.
For users of sctp_checksum_disable, skb->ip_summed should be left as
CHECKSUM_NONE and not CHECKSUM_UNNECESSARY as per include/linux/skbuff.h.

The xt_quota2 came from
http://sourceforge.net/projects/xtables-addons/develop
It needed tweaking for it to compile within the kernel tree.
Fixed kmalloc() and create_proc_entry() invocations within
a non-interruptible context.
Removed useless copying of current quota back to the iptable's
struct matchinfo:
- those are per CPU: they will change randomly based on which
cpu gets to update the value.
- they prevent matching a rule: e.g.
-A chain -m quota2 --name q1 --quota 123
can't be followed by
-D chain -m quota2 --name q1 --quota 123
as the 123 will be compared to the struct matchinfo's quota member.

Because struct rpcbind_args *map was declared static, if two
threads entered this method at the same time, the values
assigned to map could be sent two two differen tasks.
This could cause all sorts of problems, include use-after-free
and double-free of memory.
Fix this by removing the static declaration so that the map
pointer is on the stack.

- counts quota at a per CPU level
(was written back when ubiquitous SMP was just a dream)
- provides no way to count across IPV4/IPV6.

In some cases it will be useful having the key size used for
encrypting the link. For example, some profiles may restrict
some operations depending on the key length.
The key size is stored in the key that is passed to userspace
using the pin_length field in the key structure.
For now this field is only valid for LE controllers. 3.0+HS
controllers define the Read Encryption Key Size command, this
field is intended for storing the value returned by that
command.
