We incorrectly compare the mask and the result is that we can't modify

Sometimes an in-progress call will stop responding on the fileserver when
the fileserver quietly cancels the call with an internally marked abort
(RX_CALL_DEAD), without sending an ABORT to the client.
This causes the client's call to eventually expire from lack of incoming
packets directed its way, which currently leads to it being cancelled
locally with ETIME. Note that it's not currently clear as to why this
happens as it's really hard to reproduce.
The rotation policy implement by kAFS, however, doesn't differentiate
between ETIME meaning we didn't get any response from the server and ETIME
meaning the call got cancelled mid-flow. The latter leads to an oops when
fetching data as the rotation partially resets the afs_read descriptor,
which can result in a cleared page pointer being dereferenced because that
page has already been filled.
Handle this by the following means:
(1) Set a flag on a call when we receive a packet for it.
(2) Store the highest packet serial number so far received for a call
(bearing in mind this may wrap).
(3) If, when the "not received anything recently" timeout expires on a
call, we've received at least one packet for a call and the connection
as a whole has received packets more recently than that call, then
cancel the call locally with ECONNRESET rather than ETIME.
This indicates that the call was definitely in progress on the server.
(4) In kAFS, if the rotation algorithm sees ECONNRESET rather than ETIME,
don't try the next server, but rather abort the call.
This avoids the oops as we don't try to reuse the afs_read struct.
Rather, as-yet ungotten pages will be reread at a later data.
Also:
(5) Add an rxrpc tracepoint to log detection of the call being reset.
Without this, I occasionally see an oops like the following:

Commit bf6fa2c893c5 ("bpf: implement bpf_get_current_cgroup_id()
helper") introduced a new helper bpf_get_current_cgroup_id().
The helper has a dependency on CONFIG_CGROUPS.
When CONFIG_CGROUPS is not defined, using the helper will result
the following verifier error:
kernel subsystem misconfigured func bpf_get_current_cgroup_id#80
which is hard for users to interpret.
Guarding the reference to bpf_get_current_cgroup_id_proto with
CONFIG_CGROUPS will result in below better message:
unknown func bpf_get_current_cgroup_id#80

Björn Töpel says:
====================
An issue with the current AF_XDP uapi raised by Mykyta Iziumtsev (see
https://www.spinics.net/lists/netdev/msg503664.html) is that it does
not support NICs that have a "type-writer" model in an efficient
way. In this model, a memory window is passed to the hardware and
multiple frames might be filled into that window, instead of just one
that we have in the current fixed frame-size model.
This patch set fixes two bugs in the current implementation and then
changes the uapi so that the type-writer model can be supported
efficiently by a possible future extension of AF_XDP.
These are the uapi changes in this patch:
* Change the "u32 idx" in the descriptors to "u64 addr". The current
idx based format does NOT work for the type-writer model (as packets
can start anywhere within a frame) but that a relative address
pointer (the u64 addr) works well for both models in the prototype
code we have that supports both models. We increased it from u32 to
u64 to support umems larger than 4G. We have also removed the u16
offset when having a "u64 addr" since that information is already
carried in the least significant bits of the address.
* We want to use "u8 padding[5]" for something useful in the future
(since we are not allowed to change its name), so we now call it
just options so it can be extended for various purposes in the
future. It is an u32 as that it what is left of the 16 byte
descriptor.
* We changed the name of frame_size in the UMEM_REG setsockopt to
chunk_size since this naming also makes sense to the type-writer
model.
With these changes to the uapi, we believe the type-writer model can
be supported without having to resort to a new descriptor format. The
type-writer model could then be supported, from the uapi point of
view, by setting a flag at bind time and providing a new flag bit in
the options field of the descriptor that signals to user space that
all packets have been written in a chunk. Or with a new chunk
completion queue as suggested by Mykyta in his latest feedback mail on
the list.
We based this patch set on bpf-next commit bd3a08aaa9a3 ("bpf:
flowlabel in bpf_fib_lookup should be flowinfo")
The structure of the patch set is as follows:
Patches 1-2: Fixes two bugs in the current implementation.
Patches 3-4: Prepares the uapi for a "type-writer" model and modifies
the sample application so that it works with the new
uapi.
Patch 5: Small performance improvement patch for the sample application.
Cheers: Magnus and Björn

The following code fails to allocate a buffer for the
tail address that the hardware DMAs into when the user
context DMA_RTAIL is set.
if (HFI1_CAP_KGET_MASK(rcd->flags, DMA_RTAIL)) {
rcd->rcvhdrtail_kvaddr = dma_zalloc_coherent(
&dd->pcidev->dev, PAGE_SIZE, &dma_hdrqtail,
gfp_flags);
if (!rcd->rcvhdrtail_kvaddr)
goto bail_free;
rcd->rcvhdrqtailaddr_dma = dma_hdrqtail;
}
So the rcvhdrtail_kvaddr would then be NULL.
The mmap logic fails to check for a NULL rcvhdrtail_kvaddr.
The fix is to test for both user and kernel DMA_TAIL options
during the allocation as well as testing for a NULL
rcvhdrtail_kvaddr during the mmap processing.
Additionally, all downstream testing of the capmask for DMA_RTAIL
have been eliminated in favor of testing rcvhdrtail_kvaddr.

sh_eth: fix & clean up sh_eth_soft_swap()
Here's a set of 3 patches against DaveM's 'net-next.git' repo. First one fixes an
old buffer endiannes issue (luckily, the ARM SoCs are smart enough to not actually
care) plus couple clean ups around sh_eth_soft_swap()...

When initializing 'maxp' in sh_eth_soft_swap(), the buffer length needs
to be rounded up -- that's just asking for DIV_ROUND_UP()!

sh_eth_tsu_soft_swap() is called twice by the driver, remove *inline* and
move that function from the header to the driver itself to let gcc decide
whether to expand it inline or not...

Browsing thru the driver disassembly, I noticed that ARM gcc generated
no code whatsoever for sh_eth_soft_swap() while building a little-endian
kernel -- apparently __LITTLE_ENDIAN__ was not being #define'd, however
it got implicitly #define'd when building with the SH gcc (I could only
find the explicit #define __LITTLE_ENDIAN that was #include'd when building
a little-endian kernel). Luckily, the Ether controller only doing big-
endian DMA is encountered on the early SH771x SoCs only and all ARM SoCs
implement EDMR.DE and thus set 'sh_eth_cpu_data::hw_swap'. But anyway, we
need to fix the #ifdef inside sh_eth_soft_swap() to something that would
work on all architectures...

We already earlier discouraged people from using this interface in
commit 88796e7e5c45 ("sched/swait: Document it clearly that the swait
facilities are special and shouldn't be used"), but I just got a pull
request with a new broken user.
So make the comment *really* clear.
The swait interfaces are bad, and should not be used unless you have
some *very* strong reasons that include tons of hard performance numbers
on just why you want to use them, and you show that you actually
understand that they aren't at all like the normal wait/wakeup
interfaces.
So far, every single user has been suspect. The main user is KVM, which
is completely pointless (there is only ever one waiter, which avoids the
interface subtleties, but also means that having a queue instead of a
pointer is counter-productive and certainly not an "optimization").
So make the comments much stronger.
Not that anybody likely reads them anyway, but there's always some
slight hope that it will cause somebody to think twice.
I'd like to remove this interface entirely, but there is the theoretical
possibility that it's actually the right thing to use in some situation,
most likely some deep RT use.

Pull spi updates from Mark Brown:
"Quite a busy release for SPI, mainly as a result of Boris Brezillon's
work on improving the integration with MTD for accelerated SPI flash
controllers. He's added a new spi_mem interface which works a lot
better with general hardware and converted the users over to it, as a
result of this work we've got some MTD changes in here as well.
Other highlights include:
- Lots of spring cleaning for the s3c64xx driver.
- Removal of the bcm53xx, the hardware is also supported by the mspi
driver but SoC naming had caused people to miss the duplication.
- Conversion of the pxa2xx driver to use the standard message
processing loop rather than open coding.
- A bunch of improvements to the runtime PM of the OMAP McSPI driver"
