git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper changes from Mike Snitzer:
- Allow the thin target to paired with any size external origin; also
allow thin snapshots to be larger than the external origin.
- Add support for quickly loading a repetitive pattern into the
dm-switch target.
- Use per-bio data in the dm-crypt target instead of always using a
mempool for each allocation. Required switching to kmalloc alignment
for the bio slab.
- Fix DM core to properly stack the QUEUE_FLAG_NO_SG_MERGE flag
- Fix the dm-cache and dm-thin targets' export of the minimum_io_size
to match the data block size -- this fixes an issue where mkfs.xfs
would improperly infer raid striping was in place on the underlying
storage.
- Small cleanups in dm-io, dm-mpath and dm-cache

Pull x86/apic updates from Thomas Gleixner:
"This is a major overhaul to the x86 apic subsystem consisting of the
following parts:
- Remove obsolete APIC driver abstractions (David Rientjes)
- Use the irqdomain facilities to dynamically allocate IRQs for
IOAPICs. This is a prerequisite to enable IOAPIC hotplug support,
and it also frees up wasted vectors (Jiang Liu)
- Misc fixlets.
Despite the hickup in Ingos previous pull request - caused by the
missing fixup for the suspend/resume issue reported by Borislav - I
strongly recommend that this update finds its way into 3.17. Some
history for you:
This is preparatory work for physical IOAPIC hotplug. The first
attempt to support this was done by Yinghai and I shot it down because
it just added another layer of obscurity and complexity to the already
existing mess without tackling the underlying shortcomings of the
current implementation.
After quite some on- and offlist discussions, I requested that the
design of this functionality must use generic infrastructure, i.e.
irq domains, which provide all the mechanisms to dynamically map linux
interrupt numbers to physical interrupts.
Jiang picked up the idea and did a great job of consolidating the
existing interfaces to manage the x86 (IOAPIC) interrupt system by
utilizing irq domains.
The testing in tip, Linux-next and inside of Intel on various machines
did not unearth any oddities until Borislav exposed it to one of his
oddball machines. The issue was resolved quickly, but unfortunately
the fix fell through the cracks and did not hit the tip tree before
Ingo sent the pull request. Not entirely Ingos fault, I also assumed
that the fix was already merged when Ingo asked me whether he could
send it.
Nevertheless this work has a proper design, has undergone several
rounds of review and the final fallout after applying it to tip and
integrating it into Linux-next has been more than moderate. It's the
ground work not only for IOAPIC hotplug, it will also allow us to move
the lowlevel vector allocation into the irqdomain hierarchy, which
will benefit other architectures as well. Patches are posted already,
but they are on hold for two weeks, see below.
I really appreciate the competence and responsiveness Jiang has shown
in course of this endavour. So I'm sure that any fallout of this will
be addressed in a timely manner.
FYI, I'm vanishing for 2 weeks into my annual kids summer camp kitchen
duty^Wvacation, while you folks are drooling at KS/LinuxCon :) But HPA
will have a look at the hopefully zero fallout until I'm back"

If do_journal_release() races with do_journal_end() which requeues
delayed works for transaction flushing, we can leave work items for
flushing outstanding transactions queued while freeing them. That
results in use after free and possible crash in run_timers_softirq().
Fix the problem by not requeueing works if superblock is being shut down
(MS_ACTIVE not set) and using cancel_delayed_work_sync() in
do_journal_release().

Christopher reports that perf_event_print_debug() can crash in uniprocessor
builds. The crash is due to pcr_ops being NULL.
This happens because pcr_arch_init() is only invoked by smp_cpus_done() which
only executes in SMP builds.
init_hw_perf_events() is closely intertwined with pcr_ops being setup properly,
therefore:
1) Call pcr_arch_init() early on from init_hw_perf_events(), instead of
from smp_cpus_done().
2) Do not hook up a PMU type if pcr_ops is NULL after pcr_arch_init().
3) Move init_hw_perf_events to a later initcall so that it we will be
sure to invoke pcr_arch_init() after all cpus are brought up.
Finally, guard the one naked sequence of pcr_ops dereferences in
__global_pmu_self() with an appropriate NULL check.

nmi_cpu_busy() is a SMP function call that just makes sure that all of the
cpus are spinning using cpu cycles while the NMI test runs.
It does not need to disable IRQs because we just care about NMIs executing
which will even with 'normal' IRQs disabled.
It is not legal to enable hard IRQs in a SMP cross call, in fact this bug
triggers the BUG check in irq_work_run_list():
BUG_ON(!irqs_disabled());
Because now irq_work_run() is invoked from the tail of
generic_smp_call_function_single_interrupt().

In case we configured the adapter to be a wake up source from
Wake-on-LAN, but we never actually woke up using Wake-on-LAN, we will
leave the adapter in MagicPacket matching mode, which prevents any other
type of packets from reaching the RX engine. Fix this by calling
bcmgenet_power_up() with GENET_POWER_WOL_MAGIC to restore the adapter
configuration in bcmgenet_resume().
The second problem we had was an imbalanced clock disabling in
bcmgenet_wol_resume(), the Wake-on-LAN slow clock is only enabled in
bcmgenet_suspend() if we configured Wake-on-LAN, yet we unconditionally
disabled the clock in bcmgenet_wol_resume().

When we bring the interface down, phy_stop() will schedule the PHY state
machine to call our link adjustment callback. By the time we do so, we
may have clock gated off the GENET hardware block, and this will cause
bus errors to happen in bcmgenet_mii_setup():
Make sure that we only touch the UMAC_CMD register when there is an
actual link. This is safe to do for two reasons:
- updating the Ethernet MAC registers only make sense when a physical
link is present
- the PHY library state machine first set phydev->link = 0 before

Make sure that we properly suspend and resume the PHY device when we
enter low power modes. We had two calls to bcmgenet_mii_reset() which
will issue a software-reset to the PHY without using the PHY library,
get rid of them since they are completely bogus and mess up with the PHY
library state. Make sure that we reset the PHY library cached values
(link, pause and duplex) to allow the link adjustment callback to be
invoked when needed.

bcmgenet_set_hw_params() will read the hardware version and compare it
with the one we are getting from Device Tree. Due to the clock being
enabled too late, bcmgenet_set_hw_params() will cause bus errors since
the GENET hardware block is still gated off by the time
bcmgenet_set_hw_params() is called, this will also make us fail the
version check since we will read the value 0 from the hardware.
Fix this by requesting the clock before the first piece of code that
needs to access hardware register.

There is a long known problem with the netfront/netback interface: if the guest
tries to send a packet which constitues more than MAX_SKB_FRAGS + 1 ring slots,
it gets dropped. The reason is that netback maps these slots to a frag in the
frags array, which is limited by size. Having so many slots can occur since
compound pages were introduced, as the ring protocol slice them up into
individual (non-compound) page aligned slots. The theoretical worst case
scenario looks like this (note, skbs are limited to 64 Kb here):
linear buffer: at most PAGE_SIZE - 17 * 2 bytes, overlapping page boundary,
using 2 slots
first 15 frags: 1 + PAGE_SIZE + 1 bytes long, first and last bytes are at the
end and the beginning of a page, therefore they use 3 * 15 = 45 slots
last 2 frags: 1 + 1 bytes, overlapping page boundary, 2 * 2 = 4 slots
Although I don't think this 51 slots skb can really happen, we need a solution
which can deal with every scenario. In real life there is only a few slots
overdue, but usually it causes the TCP stream to be blocked, as the retry will
most likely have the same buffer layout.
This patch solves this problem by linearizing the packet. This is not the
fastest way, and it can fail much easier as it tries to allocate a big linear
area for the whole packet, but probably easier by an order of magnitude than
anything else. Probably this code path is not touched very frequently anyway.

Currently the functionality to untag traffic on input resides
as part of the vlan module and is build only when VLAN support
is enabled in the kernel. When VLAN is disabled, the function
vlan_untag() turns into a stub and doesn't really untag the
packets. This seems to create an interesting interaction
between VMs supporting checksum offloading and some network drivers.
There are some drivers that do not allow the user to change
tx-vlan-offload feature of the driver. These drivers also seem
to assume that any VLAN-tagged traffic they transmit will
have the vlan information in the vlan_tci and not in the vlan
header already in the skb. When transmitting skbs that already
have tagged data with partial checksum set, the checksum doesn't
appear to be updated correctly by the card thus resulting in a
failure to establish TCP connections.
The following is a packet trace taken on the receiver where a
sender is a VM with a VLAN configued. The host VM is running on
doest not have VLAN support and the outging interface on the
host is tg3:
10:12:43.503055 52:54:00:ae:42:3f > 28:d2:44:7d:c2:de, ethertype 802.1Q
(0x8100), length 78: vlan 100, p 0, ethertype IPv4, (tos 0x0, ttl 64, id 27243,
offset 0, flags [DF], proto TCP (6), length 60)
10.0.100.1.58545 > 10.0.100.10.ircu-2: Flags [S], cksum 0xdc39 (incorrect
-> 0x48d9), seq 1069378582, win 29200, options [mss 1460,sackOK,TS val
4294837885 ecr 0,nop,wscale 7], length 0
10:12:44.505556 52:54:00:ae:42:3f > 28:d2:44:7d:c2:de, ethertype 802.1Q
(0x8100), length 78: vlan 100, p 0, ethertype IPv4, (tos 0x0, ttl 64, id 27244,
offset 0, flags [DF], proto TCP (6), length 60)
10.0.100.1.58545 > 10.0.100.10.ircu-2: Flags [S], cksum 0xdc39 (incorrect
-> 0x44ee), seq 1069378582, win 29200, options [mss 1460,sackOK,TS val
4294838888 ecr 0,nop,wscale 7], length 0
This connection finally times out.
I've only access to the TG3 hardware in this configuration thus have
only tested this with TG3 driver. There are a lot of other drivers
that do not permit user changes to vlan acceleration features, and
I don't know if they all suffere from a similar issue.
The patch attempt to fix this another way. It moves the vlan header
stipping code out of the vlan module and always builds it into the
kernel network core. This way, even if vlan is not supported on
a virtualizatoin host, the virtual machines running on top of such
host will still work with VLANs enabled.

Netfilter fixes for net
The following patchset contains fixes for your net tree, they are:
1) Unitialize the set element key and data from the commit path,
otherwise this leaks chain refcount if the transaction is aborted,
reported by Thomas Graf.
2) Fix crash when updating chains without no counters in nf_tables,
this slipped through in the new transaction infrastructure, reported
by Matteo Croce.
3) Replace all mutex_lock_interruptible() by mutex_lock() in the Netfilter
tree, suggested by Patrick McHardy. This implicitly fixes the problem
that Eric Dumazet reported in: http://patchwork.ozlabs.org/patch/373076/
4) Fix error return code in nf_tables when deleting set element in
nf_tables if the transaction cannot be allocated, from Julia Lawall.

Since 3.14 we had copy_tree() get the shadowing wrong - if we had one
vfsmount shadowing another (i.e. if A is a slave of B, C is mounted
on A/foo, then D got mounted on B/foo creating D' on A/foo shadowed
by C), copy_tree() of A would make a copy of D' shadow the the copy of
C, not the other way around.
It's easy to fix, fortunately - just make sure that mount follows
the one that shadows it in mnt_child as well as in mnt_hash, and when
copy_tree() decides to attach a new mount, check if the last child
it has added to the same parent should be shadowing the new one.
And if it should, just use the same logics commit_tree() has - put the
new mount into the hash and children lists right after the one that
should shadow it.
