What about using bulk free of SKBs here?
There is a very high probability that we are hitting SLUB slowpath,
which involves an expensive locked cmpxchg_double per packet. Instead
we can amortize this cost via kmem_cache_free_bulk().
Maybe extend kfree_skb_list() to hide the slab/kmem_cache call?

* [PATCH v2] net: mvneta: Remove superfluous SMP function call
From: Anna-Maria Gleixner @ 2016-05-02 9:02 UTC (permalink / raw)
To: linux-kernel; +Cc: rt, Anna-Maria Gleixner, Thomas Petazzoni, netdev
Since commit 3b9d6da67e11 ("cpu/hotplug: Fix rollback during error-out
in __cpu_disable()") it is ensured that callbacks of CPU_ONLINE and
CPU_DOWN_PREPARE are processed on the hotplugged CPU. Due to this SMP
function calls are no longer required.
Replace smp_call_function_single() with a direct call to
mvneta_percpu_enable() or mvneta_percpu_disable(). The functions do
not require to be called with interrupts disabled, therefore the
smp_call_function_single() calling convention is not preserved.

Since this driver handles one frame at a time, I couldn't find a case that requires the paired barrier.
The order of reads is not critical once it is assured that the value is valid.
If there is something I'm missing or for the sake of good order, I can add it.
Please let me know your opinion on this.
I will remove the empty lines in the commit messages at the next patches version.

* double free issue, mvpp2 driver, armada375 modules
From: Raphael G @ 2016-05-02 9:46 UTC (permalink / raw)
To: linux-kernel, linux-arm-kernel, netdev
Cc: marcin wojtas, davem, Grégory Clement, Thomas Petazzoni

Hello,
enclosed the kernel panic we obtain after boot with a slightly patched
upstream kernel (4.5.2).
(as well as the patchset applied to the upstream kernel, so that you can
know which code we are talking about. Too bad we cannot use the upstream
kernel but we had no choice about this + we're no experts so we rely on
provided patches, adapted to our bootloader and hardware for this)
Reproduce:
boot on kernel on an armada375 module, connect to it, launch a top in
commandline
As seen with Marcin Wojtas, reverting commit
e864b4c7b184bde36fa6a02bb3190983d2f796f9 fixes this issue.
Reporting upstream so that you can decide what should be done next
Tell me if you need more information
Regards
Raphael

Please see sections "SMP BARRIER PAIRING" and "EXAMPLES OF MEMORY BARRIER SEQUENCES" in
memory-barriers.txt for a description why smp barriers have to be paired and a smp write
barrier on CPU A without a read barrier on CPU B is _not_ sufficient.
Furthermore after having a closer look into the problem you want to fix, it seems that
you also have to ensure the correct order of the assignment of "tx_packet_sent" and the
corresponding skb.
On CPU A you do:
1. tx_skb = skb;
2. tx_packet_sent = true;
On CPU B (the irq handler) you do:
1. Check/read tx_packet_sent.
2.If set then handle tx_skb.
So there is a logical dependency between tx_skb and tx_packet_sent (tx_skb should only
be handled if tx_packet_sent is set). However both compiler and CPU are free to reorder
steps 1. and 2. on both CPU A and CPU B and you have to ensure that tx_skb actually contains
a valid pointer for CPU B as soon at it sees tx_packet_sent == true. So what you need here is:
CPU A:
1. tx_skb = skb
2. smp_wmb()
3. tx_packet_sent = true;
and CPU B:
1. read tx_packet_sent
2. smp_rmb()
3. If set then handle tx_skb
So this is to ensure that tx_skb is in sync with tx_packet_sent on both writer and reader side.
Then there is the second problem (the one you tried to address with your patch) that you have to make
sure that by the time you inform the hardware about the new frame and the thus the tx-done irq may occur
both tx_packet_sent and tx_skb are actually set in the memory. Otherwise the irq may occur but CPU B may
not see tx_packet_sent == true and the irq is lost. To achieve this you would have to use a (non-smp)
write barrier before you inform the HW. So for CPU A the sequence would extend to:
1. tx_skb = skb
2. smp_wmb() /* ensure correct order between both assignments */
3. tx_packet_sent = true;
4. wmb() /* make sure both assignments reach RAM before the HW is informed and the IRQ is fired */
5. nps_enet_reg_set(priv, NPS_ENET_REG_TX_CTL, tx_ctrl.value);
The latter barrier does not require pairing and has to be there even on UP systems because you dont want to
sync between CPU A and CPU B in this case but rather between system RAM and IO-MEMORY.
Please note that this is only how I understood things and it may be totally wrong. But I am sure that the initial
solution with only one smp_wmb() is not correct either.
Regards,
Lino

Hi Dave,
another pull request for 4.7. Nothing really special, from the diffstat
stands out a new bindings document for Marvell but I can't think of
anything else special worth mentioning.
Please let me know if there are any problems.

* [PATCH net-next 1/3] tipc: re-enable compensation for socket receive buffer double counting
From: Jon Maloy @ 2016-05-02 14:22 UTC (permalink / raw)
To: davem; +Cc: Jon Maloy, netdev, Paul Gortmaker, tipc-discussion
In-Reply-To: <1462198956-30181-1-git-send-email-jon.maloy@ericsson.com>
In the refactoring commit d570d86497ee ("tipc: enqueue arrived buffers
in socket in separate function") we did by accident replace the test
if (sk->sk_backlog.len == 0)
atomic_set(&tsk->dupl_rcvcnt, 0);
with
if (sk->sk_backlog.len)
atomic_set(&tsk->dupl_rcvcnt, 0);
This effectively disables the compensation we have for the double
receive buffer accounting that occurs temporarily when buffers are
moved from the backlog to the socket receive queue. Until now, this
has gone unnoticed because of the large receive buffer limits we are
applying, but becomes indispensable when we reduce this buffer limit
later in this series.
We now fix this by inverting the mentioned condition.

* [PATCH net-next 2/3] tipc: propagate peer node capabilities to socket layer
From: Jon Maloy @ 2016-05-02 14:22 UTC (permalink / raw)
To: davem; +Cc: Jon Maloy, netdev, Paul Gortmaker, tipc-discussion
In-Reply-To: <1462198956-30181-1-git-send-email-jon.maloy@ericsson.com>
During neighbor discovery, nodes advertise their capabilities as a bit
map in a dedicated 16-bit field in the discovery message header. This
bit map has so far only be stored in the node structure on the peer
nodes, but we now see the need to keep a copy even in the socket
structure.
This commit adds this functionality.

* [PATCH net-next 3/3] tipc: redesign connection-level flow control
From: Jon Maloy @ 2016-05-02 14:22 UTC (permalink / raw)
To: davem; +Cc: Jon Maloy, netdev, Paul Gortmaker, tipc-discussion
In-Reply-To: <1462198956-30181-1-git-send-email-jon.maloy@ericsson.com>
There are two flow control mechanisms in TIPC; one at link level that
handles network congestion, burst control, and retransmission, and one
at connection level which' only remaining task is to prevent overflow
in the receiving socket buffer. In TIPC, the latter task has to be
solved end-to-end because messages can not be thrown away once they
have been accepted and delivered upwards from the link layer, i.e, we
can never permit the receive buffer to overflow.
Currently, this algorithm is message based. A counter in the receiving
socket keeps track of number of consumed messages, and sends a dedicated
acknowledge message back to the sender for each 256 consumed message.
A counter at the sending end keeps track of the sent, not yet
acknowledged messages, and blocks the sender if this number ever reaches
512 unacknowledged messages. When the missing acknowledge arrives, the
socket is then woken up for renewed transmission. This works well for
keeping the message flow running, as it almost never happens that a
sender socket is blocked this way.
A problem with the current mechanism is that it potentially is very
memory consuming. Since we don't distinguish bewteen small and large
messages, we have to dimension the socket receive buffer according
to a worst-case of both. I.e., the window size must be chosen large
enough to sustain a reasonable throughput even for the smallest
messages, while we must still consider a scenario where all messages
are of maximum size. Hence, the current fix window size of 512 messages
and a maximum message size of 66k results in a receive buffer of 66 MB
when truesize(66k) = 131k is taken into account. It is possible to do
much better.
This commit introduces an algorithm where we instead use 1024-byte
blocks as base unit. This unit, always rounded upwards from the
actual message size, is used when we advertise windows as well as when
we count and acknowledge transmitted data. The advertised window is
based on the configured receive buffer size in such a way that even
the worst-case truesize/msgsize ratio always is covered. Since the
smallest possible message size (from a flow control viewpoint) now is
1024 bytes, we can safely assume this ratio to be less than four, which
is the value we are now using.
This way, we have been able to reduce the default receive buffer size
from 66 MB to 2 MB with maintained performance.
In order to keep this solution backwards compatible, we introduce a
new capability bit in the discovery protocol, and use this throughout
the message sending/reception path to always select the right unit.

Sounds tricky, because of skb destructors. skb are complex objects.
For each skb, need to free the frags, skb->head, and skb.

* [RESEND PATCH 1/3] rfkill: Create "rfkill-airplane-mode" LED trigger

This creates a new LED trigger to be used by platform drivers as a
default trigger for airplane-mode indicator LEDs.
By default this trigger will fire when RFKILL_OP_CHANGE_ALL is called
for all types (RFKILL_TYPE_ALL), setting the LED brightness to LED_FULL
when the changing the state to blocked, and to LED_OFF when the changing
the state to unblocked. In the future there will be a mechanism for
userspace to override the default policy, so it can implement its own.
This trigger will be used by the asus-wireless x86 platform driver.

Provide an interface for the airplane-mode indicator be controlled from
userspace. User has to first acquire the control through
RFKILL_OP_AIRPLANE_MODE_INDICATOR_ACQUIRE and keep the fd open for the
whole time it wants to be in control of the indicator. Closing the fd
restores the default policy.
To change state of the indicator, the
RFKILL_OP_AIRPLANE_MODE_INDICATOR_CHANGE operation is used, passing the
value on "struct rfkill_event.soft". If the caller has not acquired the
airplane-mode control beforehand, the operation fails.

This series implements an airplane-mode indicator LED trigger, which can be
used by platform drivers. By default the trigger fires on RFKILL_OP_CHANGE_ALL,
but this policy can be overwritten by userspace using the new operations
_AIRPLANE_MODE_INDICATOR_ACQUIRE and _AIRPLANE_MODE_INDICATOR_CHANGE. When the
airplane-mode indicator state changes, userspace gets notifications through the
RFKill control misc device (/dev/rfkill). I also have patches to the rfkill
userspace tool that makes use of this interface, so it can serve as API usage
example and to do quick checks on a running system, which I'll send in a
separate series.
After some hiatus I found the time to get back to this, and this time I've used
Jouni's hwsim suite to test the patches on top of mac80211-next/master. Lines
containing rfkill are pasted bellow:

NACK
This patch is correct. There is a logic error in entering/exiting power-save
mode. Thus the code part is OK; however, the subject and commit message need to
be improved. If I had prepared this patch, my subject would have been "rtlwifi:
Fix logic error in enter/exit power-save mode". For the commit message, I would
have used the following:
In commit fd09ff958777 ("rtlwifi: Remove extra workqueue for enter/leave power
state"), the tests for enter/exit power-save mode were inverted. With this
change applied, the wifi connection becomes much more stable.
Fixes: fd09ff958777 ("rtlwifi: Remove extra workqueue for enter/leave power state")

I have some documentation in
Documentation/networking/segmentation-offloads.txt. Feel free to
review it and provide any additional feedback and/or patches you
believe it needs. To me it made sense but I already understood how
all this stuff worked.

Actually in the case of GSO partial we have go through the software
segmentation code and trim off any last bit that doesn't match the MSS
of the rest of the frame. That way you end up with one frame that has
some number of MSS sized chunks, and then one remainder if there is a
frame that would be a different size.

* [PATCH net-next 1/3] tipc: re-enable compensation for socket receive buffer double counting
From: Jon Maloy @ 2016-05-02 15:58 UTC (permalink / raw)
To: davem; +Cc: Jon Maloy, netdev, Paul Gortmaker, tipc-discussion
In-Reply-To: <1462204727-9224-1-git-send-email-jon.maloy@ericsson.com>
In the refactoring commit d570d86497ee ("tipc: enqueue arrived buffers
in socket in separate function") we did by accident replace the test
if (sk->sk_backlog.len == 0)
atomic_set(&tsk->dupl_rcvcnt, 0);
with
if (sk->sk_backlog.len)
atomic_set(&tsk->dupl_rcvcnt, 0);
This effectively disables the compensation we have for the double
receive buffer accounting that occurs temporarily when buffers are
moved from the backlog to the socket receive queue. Until now, this
has gone unnoticed because of the large receive buffer limits we are
applying, but becomes indispensable when we reduce this buffer limit
later in this series.
We now fix this by inverting the mentioned condition.

* [PATCH net-next 2/3] tipc: propagate peer node capabilities to socket layer
From: Jon Maloy @ 2016-05-02 15:58 UTC (permalink / raw)
To: davem; +Cc: Jon Maloy, netdev, Paul Gortmaker, tipc-discussion
In-Reply-To: <1462204727-9224-1-git-send-email-jon.maloy@ericsson.com>
During neighbor discovery, nodes advertise their capabilities as a bit
map in a dedicated 16-bit field in the discovery message header. This
bit map has so far only be stored in the node structure on the peer
nodes, but we now see the need to keep a copy even in the socket
structure.
This commit adds this functionality.
