I have no idea how you set this up, but there is no WAY this can be
pulled from by me.
When I try to pull it into 'net' I get 2690 objects. That means you
didn't base it upon the 'net' tree which you must do. You can't base
it upon Linus's tree, because if you do I'll get a ton of changes that
are absolutely not appropriate to be pulled into my 'net' tree.
Are you always doing this? Working against Linus's tree instead of
mine?

Sorry, whilst I realize your problem, I'm not going to add what is
explicitly a violation of the way link-local addresses are meant to
work and the very much intentional restrictions the RFCs place upon
them (they MUST not be routed).
I also didn't see any real discussions in response to your original
proposals, not from even one person I know is knowledgable about ipv6
and the implications your change would have, and that is extremely
troubling.
I tried to let your patches sit for several days in order to let that
kind of discussion happen, but it didn't.
So, you'll need to find another way to achieve your goals.

There is no point in having a special case for the revision when probing
a switch model. The code gets cluttered with unnecessary defines, and
leads to errors when code such as mv88e6131_setup compares
PORT_SWITCH_ID_6131_B2 to ps->id which masks the revision.
Drop every revision definition, and lookup only the product number.

Drop the ps->num_ports variable in favor of a new member of the info
structure. This removes the need to assign it at setup time.

* [PATCH net-next v3 0/8] net: dsa: mv88e6xxx: factorize switch info
From: Vivien Didelot @ 2016-04-16 22:41 UTC (permalink / raw)
To: netdev
Cc: linux-kernel, kernel, David S. Miller, Florian Fainelli,
Andrew Lunn, Vivien Didelot
This patchset factorizes the mv88e6xxx code by sharing a new extendable
info structure to store static data such as switch family, product
number, number of ports, number of databases and the name.
The next step is to add a "flags" bitmap member to the info structure in
order to simplify the shared code with a feature-based logic instead of
checking their family/ID.
This is a step forward having a single mv88e6xxx driver supporting many
similar devices, like any usual Linux driver.
Changes v2 -> v3:
- update commit messages and add Andrew's tags
- keep the info lookup code in a separated function
- split the single switch ID reading in probe in a new commit
Changes v1 -> v2:
- define PORT_SWITCH_ID_PROD_NUM_* values
- use plain struct mv88e6xxx_info
- remove non used yet ps->rev

Current code is assuming that the address returned by dma_alloc_coherent
is a logical address. This is not true on ARM/ARM64 systems. This patch
replaces dma_alloc_coherent with dma_map_page API. The address returned
can later by virtually mapped from the CPU side with vmap API.

The reason is that while I felt confident in understanding the problem
and its solution, I didn't realize that bound follows portid, and that,
for example, a kernel socket can't get bound. :-)
But yeah - looking at the code after your comment does show that
testing portid is pointless now.
In fact, now that I look at it, I wonder how this situation came about?
In the current code, you can only trigger the problematic situation
through an error condition, afaict - you have to try to bind a socket
with the same portid as an already existing one, and __netlink_insert()
will then fail, but netlink_insert() won't reset the nlk_sk(sk)->portid
since your commit da314c9923fe ("netlink: Replace rhash_portid with
bound"), even though you had previously fixed precisely this issue
already - commit c0bb07df7d98 ("netlink: Reset portid after
netlink_insert failure"). You then close the socket, and since portid
is assigned, that will trigger NETLINK_URELEASE.
So before the rhash_portid -> bound change, this doesn't seem to have
been a problem, and I guess we didn't get the "stuck in limbo" problem
back because we now check bound everywhere relevant, for purposes of
calling netlink_autobind.
IOW - I'm now even more convinced that the patch is correct, and I'm
also convinced that until fairly recently (da314c9923fe) this wasn't
even a problem.
Maybe we can take the opportunity of removing the "portid" check to put
most of the above into a commit message, but I think you should review
it first.

* [PATCH] ixgbe: use msleep for long delays

The newly added x550em_a support causes a link failure on ARM because of
an overly long time passed into udelay():
ERROR: "__bad_udelay" [drivers/net/ethernet/intel/ixgbe/ixgbe.ko] undefined!
There are multiple variants of the ixgbe_acquire_swfw_sync_*() function,
and the other ones all use msleep(), so we can safely assume that all
callers are allowed to sleep, which makes msleep() a better replacement
than mdelay().

* [PATCH] bpf: avoid warning for wrong pointer cast
From: Arnd Bergmann @ 2016-04-16 20:29 UTC (permalink / raw)
To: David S . Miller

Two new functions in bpf contain a cast from a 'u64' to a
pointer. This works on 64-bit architectures but causes a warning
on all 32-bit architectures:
kernel/trace/bpf_trace.c: In function 'bpf_perf_event_output_tp':
kernel/trace/bpf_trace.c:350:13: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
u64 ctx = *(long *)r1;
This changes the cast to first convert the u64 argument into a uintptr_t,
which is guaranteed to be the same size as a pointer.

* [PATCH] devlink: fix devlink_sb_register prototype
From: Arnd Bergmann @ 2016-04-16 20:27 UTC (permalink / raw)
To: Jiri Pirko, David S. Miller
Cc: Arnd Bergmann, Ido Schimmel, netdev, linux-kernel
The devlink shared buffer interface contains two different
prototypes for devlink_sb_register, and the one that is
used when NET_DEVLINK is disabled does not work:
drivers/net/ethernet/mellanox/mlxsw/spectrum_buffers.c: In function 'mlxsw_sp_buffers_init':
drivers/net/ethernet/mellanox/mlxsw/spectrum_buffers.c:547:9: error: too many arguments to function 'devlink_sb_register'
return devlink_sb_register(priv_to_devlink(mlxsw_sp->core), 0,
This makes the two prototypes have the same argument list.
