Unfortunately, I never committed the fix to a nasty oops which can
occur as a result of that commit:
------------[ cut here ]------------
kernel BUG at /home/olof/work/batch/include/linux/mm.h:414!
Internal error: Oops - BUG: 0 [#1] PREEMPT SMP ARM
Modules linked in:

PC is at special_mapping_fault+0xa4/0xc4
LR is at __do_fault+0x68/0x48c
This doesn't show up unless you do quite a bit of testing; a simple
boot test does not do this, so all my nightly tests were passing fine.
The reason for this is that install_special_mapping() expects the
page array to stick around, and as this was only inserting one page
which was stored on the kernel stack, that's why this was blowing up.

NetLabel has the ability to selectively assign network security labels
to outbound traffic based on either the LSM's "domain" (different for
each LSM), the network destination, or a combination of both. Depending
on the type of traffic, local or forwarded, and the type of traffic
selector, domain or address based, different hooks are used to label the
traffic; the goal being minimal overhead.
Unfortunately, there is a bug such that a system using NetLabel domain
based traffic selectors does not correctly label outbound local traffic
that is not assigned to a socket. The issue is that in these cases
the associated NetLabel hook only looks at the address based selectors
and not the domain based selectors. This patch corrects this by
checking both the domain and address based selectors so that the correct
labeling is applied, regardless of the configuration type.
In order to acomplish this fix, this patch also simplifies some of the
NetLabel domainhash structures to use a more common outbound traffic
mapping type: struct netlbl_dommap_def. This simplifies some of the code
in this patch and paves the way for further simplifications in the
future.

It's possible to assign an invalid value to the net.core.somaxconn
sysctl variable, because there is no checks at all.
The sk_max_ack_backlog field of the sock structure is defined as
unsigned short. Therefore, the backlog argument in inet_listen()
shouldn't exceed USHRT_MAX. The backlog argument in the listen() syscall
is truncated to the somaxconn value. So, the somaxconn value shouldn't
exceed 65535 (USHRT_MAX).
Also, negative values of somaxconn are meaningless.
before:
$ sysctl -w net.core.somaxconn=256
net.core.somaxconn = 256
$ sysctl -w net.core.somaxconn=65536
net.core.somaxconn = 65536
$ sysctl -w net.core.somaxconn=-100
net.core.somaxconn = -100
after:
$ sysctl -w net.core.somaxconn=256
net.core.somaxconn = 256
$ sysctl -w net.core.somaxconn=65536
error: "Invalid argument" setting key "net.core.somaxconn"
$ sysctl -w net.core.somaxconn=-100
error: "Invalid argument" setting key "net.core.somaxconn"

When userspace passes a large priority value
the assignment of the unsigned value hopt->prio
to signed int cl->prio causes cl->prio to become negative and the
comparison is with TC_HTB_NUMPRIO is always false.
The result is that HTB crashes by referencing outside
the array when processing packets. With this patch the large value
wraps around like other values outside the normal range.

Pull PCI fixes from Bjorn Helgaas:
"Yinghai fixed a couple regressions: one resource assignment problem
introduced in v3.10 that showed up with SR-IOV on powerpc, and another
SR-IOV hot-remove issue related to refcounting changes we merged for
v3.11.
Yinghai is still working on another SR-IOV-related fix or two, which
will be simpler if pciehp is non-modular, so I included the Kconfig
changes now to get them in earlier.
Finally, a minor fix for the ARM Marvell EBU host bridge driver that
was merged for v3.11
Hotplug:
PCI: pciehp: Fix null pointer deref when hot-removing SR-IOV device
PCI: hotplug: Convert to be builtin only, not modular
PCI: pciehp: Convert pciehp to be builtin only, not modular
Resource allocation:

Pull ACPI and power management fixes from Rafael Wysocki:
- Revert two cpuidle commits added during the 3.8 development cycle
that turn out to have introduced a significant performance regression
as requested by Jeremy Eder.
- The recent patches that made the freezer less heavy-weight introduced
a regression causing user-space-driven hibernation using the ioctl()
interface to block indefinitely when the hibernate process executes
try_to_freeze(). Fix from Colin Cross addresses this by adding a
process flag to mark the hibernate/suspend process to inform the
freezer that that process should be ignored.
- One of the recent cpufreq reverts uncovered a problem in the core
causing the cpufreq driver module refcount to become negative after a
system suspend-resume cycle. Fix from Rafael J Wysocki.
- The evaluation of the ACPI battery _BIX method has never worked
correctly, because the commit that added support for it forgot to
take the "Revision" field in the return package into account. As a
result, the reading of battery info doesn't work at all on some
systems, which is addressed by a fix from Lan Tianyu.

We have the following call chain:
tipc_core_start()
ret = tipc_subscr_start()
ret = tipc_server_start(){
server->enabled = 1;
ret = tipc_open_listening_sock()
}
I.e., the server->enabled flag is unconditionally set to 1, whatever
the return value of tipc_open_listening_sock().
This causes a crash when tipc_core_start() tries to clean up
resources after a failed initialization:
if (ret == failed)
tipc_subscr_stop()
tipc_server_stop(){
if (server->enabled)
tipc_close_conn(){
NULL reference of con->sock-sk
OOPS!
}
}
To avoid this, tipc_server_start() should only set server->enabled
to 1 in case of a succesful socket creation. In case of failure, it
should release all allocated resources before returning.
Problem introduced in commit c5fa7b3cf3cb22e4ac60485fc2dc187fe012910f
("tipc: introduce new TIPC server infrastructure") in v3.11-rc1.
Note that it won't be seen often; it takes a module load under memory
constrained conditions in order to trigger the failure condition.

If the user has not assigned a MAC address to a VM, then don't give it MAC which
is based on the PF one. The current derivation scheme is wrong and leads to VM
MAC collisions when the number of cards/hypervisors becomes big enough.
Instead, just give it zeros and let them figure out what to do with that.

There's a race in IPv6 automatic addess assignment. The address is created
with zero lifetime when it's added to various address lists. Before it gets
assigned the correct lifetime, there's a window where a new address may be
configured. This causes the semi-initiated address to be deleted in
addrconf_verify.
This was discovered as a reference leak caused by concurrent run of
__ipv6_ifa_notify for both RTM_NEWADDR and RTM_DELADDR with the same
address.
Fix this by setting the lifetime before the address is added to
inet6_addr_lst.
A few notes:
1. In addrconf_prefix_rcv, by setting update_lft to zero, the
if (update_lft) { ... } condition is no longer executed for newly
created addresses. This is okay, as the ifp fields are set in
ipv6_add_addr now and ipv6_ifa_notify is called (and has been called)
through addrconf_dad_start.
2. The removal of the whole block under ifp->lock in inet6_addr_add is okay,
too, as tstamp is initialized to jiffies in ipv6_add_addr.

As pointed out by Eric Dumazet, net->ipv6.ip6_rt_last_gc should
hold the last time garbage collector was run so that we should
update it whenever fib6_run_gc() calls fib6_clean_all(), not only
if we got there from ip6_dst_gc().

On a high-traffic router with many processors and many IPv6 dst
entries, soft lockup in fib6_run_gc() can occur when number of
entries reaches gc_thresh.
This happens because fib6_run_gc() uses fib6_gc_lock to allow
only one thread to run the garbage collector but ip6_dst_gc()
doesn't update net->ipv6.ip6_rt_last_gc until fib6_run_gc()
returns. On a system with many entries, this can take some time
so that in the meantime, other threads pass the tests in
ip6_dst_gc() (ip6_rt_last_gc is still not updated) and wait for
the lock. They then have to run the garbage collector one after
another which blocks them for quite long.
Resolve this by replacing special value ~0UL of expire parameter
to fib6_run_gc() by explicit "force" parameter to choose between
spin_lock_bh() and spin_trylock_bh() and call fib6_run_gc() with
force=false if gc_thresh is reached but not max_size.

The Marvell PCIe driver uses an emulated PCI-to-PCI bridge to be able
to dynamically set up MBus address decoding windows for PCI I/O and
memory regions depending on the PCI devices enumerated by Linux.
However, this emulated PCI-to-PCI bridge logic makes the Linux PCI
core believe that prefetchable memory regions are supported (because
the registers are read/write), while in fact no adress decoding window
is ever created for such regions. Since the Marvell MBus address
decoding windows do not distinguish memory regions and prefetchable
memory regions, this patch takes a simple approach: change the
PCI-to-PCI bridge emulation to let the Linux PCI core know that we
don't support prefetchable memory regions.
To achieve this, we simply make the prefetchable memory base a
read-only register that always returns 0. Reading/writing all the
other prefetchable memory related registers has no effect.
This problem was originally reported by Finn Hoffmann
<finn@uni-bremen.de>, who couldn't get a RTL8111/8168B PCI NIC working
on the NSA310 Kirkwood platform after updating to 3.11-rc. The problem
was that the PCI-to-PCI bridge emulation was making the Linux PCI core
believe that we support prefetchable memory, so the Linux PCI core was
only filling the prefetchable memory base and limit registers, which
does not lead to a MBus window being created. The below patch has been
confirmed by Finn Hoffmann to fix his problem on Kirkwood, and has
otherwise been successfully tested on the Armada XP GP platform with a
e1000e PCIe NIC and a Marvell SATA PCIe card.

John W. Linville says:
====================
This pull request is intended for the 3.11 stream. It is a bit
larger than usual, as it includes pulls from most of my feeder trees
as well...
For the Bluetooth bits, Gustavo says:
"A few fixes and devices ID additions for 3.11:
* There are 4 new ath3k device ids
* Fixed stack memory usage in ath3k.
* Fixed the init process of BlueFRITZ! devices, they were failing to init
due to an unsupported command we sent.
* Fixed wrong use of PTR_ERR in btusb code that was preventing intel devices
to work properly.
* Fixed race condition between hci_register_dev() and hci_dev_open() that
could cause a NULL pointer dereference.
* Fixed race condition that could call hci_req_cmd_complete() and make some
devices to fail as showed in the log added to the commit message."
Regarding the NFC bits, Samuel says:
"We have:
1) A build failure fix for the NCI SPI transport layer due to a
missing CRC_CCITT Kconfig dependency.
2) A netlink command rename: CMD_FW_UPLOAD was merged during the 3.11
merge window but the typical terminology for loading a firmware to a
target is firmware download rather than upload. In order to avoid any
confusion in a file exported to userspace, we rename this command to
CMD_FW_DOWNLOAD."
Samuel's item #2 isn't strictly a fix, but it seems safe and should
avoid confusion in the future.
As for the mac80211 bits, Johannes says:
"I only have three fixes this time, a fix for a suspend regression, a
patch correcting the initiator in regulatory code and one fix for mesh
station powersave."
With respect to the iwlwifi bits, Johannes says:
"We have a scan fix for passive channels, a new PCI device ID for an old
device, a NIC reset fix, an RF-Kill fix, a fix for powersave when GO
interfaces are present as well as an aggregation session fix (for a
corner case) and a workaround for a firmware design issue - it only
supports a single GTK in D3."
Bringing-up the rear with the Atheros trees, Kalle says:
"Geert Uytterhoeven fixed an ath10k build problem when NO_DMA=y. I added
a missing MAINTAINERS entry for ath10k and updated ath6kl git tree
location."
Along with the above...
Arend van Spriel fixes a brcmfmac WARNING when unplugging the device.
Avinash Patil proves a couple of minor mwifiex fixes relating to P2P mode.
Luciano Coelho updates the MAINTAINERS entry for the wilink drivers.
Stanislaw Gruszka brings an rt2x00 fix for a queue start/stop problem.
Stone Piao fixes another mwifiex problem, a command timeout related to P2P mode.
Tomasz Moń corrects an endian problem in mwifiex.
I'll remind my feeder maintainers to slowdown the patchflow.
Beyond that, please let me know if there are problems!
