Marc Kleine-Budde says:
====================
I have two late fixes for the v3.12 release:
The first patch fixes a problem in the c_can's RX message handling, which can
lead to an endless interrupt loop under heavy load if messages are lost. The
second patch is by Olivier Sobrie and fixes the endpoint detection of the
kvaser_usb driver, which is needed for some devices.

Introduced in f9e42b853523 ("net: sctp: sideeffect: throw BUG if
primary_path is NULL"), we intended to find a buggy assoc that's
part of the assoc hash table with a primary_path that is NULL.
However, we better remove the BUG_ON for now and find a more
suitable place to assert for these things as Mark reports that
this also triggers the bug when duplication cookie processing
happens, and the assoc is not part of the hash table (so all
good in this case). Such a situation can for example easily be
reproduced by:
tc qdisc add dev eth0 root handle 1: prio bands 2 priomap 1 1 1 1 1 1
tc qdisc add dev eth0 parent 1:2 handle 20: netem loss 20%
tc filter add dev eth0 protocol ip parent 1: prio 2 u32 match ip \
protocol 132 0xff match u8 0x0b 0xff at 32 flowid 1:2
This drops 20% of COOKIE-ACK packets. After some follow-up
discussion with Vlad we came to the conclusion that for now we
should still better remove this BUG_ON() assertion, and come up
with two follow-ups later on, that is, i) find a more suitable
place for this assertion, and possibly ii) have a special
allocator/initializer for such kind of temporary assocs.

(HSRv0)
High-availability Seamless Redundancy ("HSR") provides instant failover
redundancy for Ethernet networks. It requires a special network topology where
all nodes are connected in a ring (each node having two physical network
interfaces). It is suited for applications that demand high availability and
very short reaction time.
HSR acts on the Ethernet layer, using a registered Ethernet protocol type to
send special HSR frames in both directions over the ring. The driver creates
virtual network interfaces that can be used just like any ordinary Linux
network interface, for IP/TCP/UDP traffic etc. All nodes in the network ring
must be HSR capable.
This code is a "best effort" to comply with the HSR standard as described in
IEC 62439-3:2010 (HSRv0).

Joby Poriyath provided a xen-netback patch to reduce the size of
xenvif structure as some netdev allocation could fail under
memory pressure/fragmentation.
This patch is handling the problem at the core level, allowing
any netdev structures to use vmalloc() if kmalloc() failed.
As vmalloc() adds overhead on a critical network path, add __GFP_REPEAT
to kzalloc() flags to do this fallback only when really needed.

This fixes an outstanding bug found through IPVS, where SCTP packets
with skb->data_len > 0 (non-linearized) and empty frag_list, but data
accumulated in frags[] member, are forwarded with incorrect checksum
letting SCTP initial handshake fail on some systems. Linearizing each
SCTP skb in IPVS to prevent that would not be a good solution as
this leads to an additional and unnecessary performance penalty on
the load-balancer itself for no good reason (as we actually only want
to update the checksum, and can do that in a different/better way
presented here).
The actual problem is elsewhere, namely, that SCTP's checksumming
in sctp_compute_cksum() does not take frags[] into account like
skb_checksum() does. So while we are fixing this up, we better reuse
the existing code that we have anyway in __skb_checksum() and use it
for walking through the data doing checksumming. This will not only
fix this issue, but also consolidates some SCTP code with core
sk_buff code, bringing it closer together and removing respectively
avoiding reimplementation of skb_checksum() for no good reason.
As crc32c() can use hardware implementation within the crypto layer,
we leave that intact (it wraps around / falls back to e.g. slice-by-8
algorithm in __crc32c_le() otherwise); plus use the __crc32c_le_combine()
combinator for crc32c blocks.
Also, we remove all other SCTP checksumming code, so that we only
have to use sctp_compute_cksum() from now on; for doing that, we need
to transform SCTP checkumming in output path slightly, and can leave
the rest intact.

Currently, skb_checksum walks over 1) linearized, 2) frags[], and
3) frag_list data and calculats the one's complement, a 32 bit
result suitable for feeding into itself or csum_tcpudp_magic(),
but unsuitable for SCTP as we're calculating CRC32c there.
Hence, in order to not re-implement the very same function in
SCTP (and maybe other protocols) over and over again, use an
update() + combine() callback internally to allow for walking
over the skb with different algorithms.

This patch adds a combinator to merge two or more crc32{,c}s
into a new one. This is useful for checksum computations of
fragmented skbs that use crc32/crc32c as checksums.
The arithmetics for combining both in the GF(2) was taken and
slightly modified from zlib. Only passing two crcs is insufficient
as two crcs and the length of the second piece is needed for
merging. The code is made generic, so that only polynomials
need to be passed for crc32_le resp. crc32c_le.

lenghts or identifier counts. Prevent them from getting negative.
Also change the underlying data types to be unsigned to avoid hairy
surprises with sign extensions in cases where those variables get

In case a user still wants to have "unlimited" sizes she could just use

When CONFIG_CIFS_STATS2 enabled query adapter info for debugging
It is easy now in SMB3 to query the information about the server's
network interfaces (and at least Windows 8 and above do this, if not
other clients) there are some useful pieces of information you can get
including:
- all of the network interfaces that the server advertises (not just
the one you are mounting over), and with SMB3 supporting multichannel
this helps with more than just failover (also aggregating multiple
sockets under one mount)
- whether the adapter supports RSS (useful to know if you want to
estimate whether setting up two or more socket connections to the same
address is going to be faster due to RSS offload in the adapter)
- whether the server supports RDMA
- whether the server has IPv6 interfaces (if you connected over IPv4
but prefer IPv6 e.g.)
- what the link speed is (you might want to reconnect over a higher
speed interface if available)
(Of course we could also rerequest this on every mount cheaplly to the
same server, as Windows apparently does, so we can update the adapter
info on new mounts, and also on every reconnect if the network
interface drops temporarily - so we don't have to rely on info from
the first mount to this server)
It is trivial to request this information - and certainly will be useful
when we get to the point of doing multichannel (and eventually RDMA),
but some of this (linkspeed etc.) info may help for debugging in
the meantime. Enable this request when CONFIG_CIFS_STATS2 is on
(only for smb3 mounts since it is an SMB3 or later ioctl).

An earlier patch allowed setting the per-file compression flag
"chattr +c filename"
on an smb2 or smb3 mount, and also allowed lsattr to return
whether a file on a cifs, or smb2/smb3 mount was compressed.
This patch extends the ability to set the per-file
compression flag to the cifs protocol, which uses a somewhat
different IOCTL mechanism than SMB2, although the payload
(the flags stored in the compression_state) are the same.

In SMB3 it is now possible to query the file system
alignment info, and the preferred (for performance)
sector size and whether the underlying disk
has no seek penalty (like SSD).
Query this information at mount time for SMB3,
and make it visible in /proc/fs/cifs/DebugData
for debugging purposes.
This alignment information and preferred sector
size info will be helpful for the copy offload
patches to setup the right chunks in the CopyChunk
requests. Presumably the knowledge that the
underlying disk is SSD could also help us
make better readahead and writebehind
decisions (something to look at in the future).

Send a smb session logoff request before removing smb session off of the list.
On a signed smb session, remvoing a session off of the list before sending
a logoff request results in server returning an error for lack of
smb signature.
Never seen an error during smb logoff, so as per MS-SMB2 3.2.5.1,
not sure how an error during logoff should be retried. So for now,
if a server returns an error to a logoff request, log the error and

The multiplex identifier (MID) in the SMB header is only
ever used by the client, in conjunction with PID, to match responses
from the server. As such, the endianess of the MID is not important.
However, When tracing packet sequences on the wire, protocol analyzers
such as wireshark display MID as little endian. It is much more informative
for the on-the-wire MID sequences to match debug information emitted by the
CIFS driver. Therefore, one should write and read MID in the SMB header
assuming it is always little endian.
Observed from wireshark during the protocol negotiation
and session setup:
Multiplex ID: 256
Multiplex ID: 256
Multiplex ID: 512
Multiplex ID: 512
Multiplex ID: 768
Multiplex ID: 768
After this patch on-the-wire MID values begin at 1 and increase monotonically.
Introduce get_next_mid64() for the internal consumers that use the full 64 bit
multiplex identifier.
Introduce the helpers get_mid() and compare_mid() to make the endian
translation clear.

A vmalloc fault needs to sync up PGD/PTE entry from init_mm to current
task's "active_mm". ARC vmalloc fault handler however was using mm.
A vmalloc fault for non user task context (actually pre-userland, from
init thread's open for /dev/console) caused the handler to deref NULL mm
(for mm->pgd)
The reasons it worked so far is amazing:
1. By default (!SMP), vmalloc fault handler uses a cached value of PGD.
In SMP that MMU register is repurposed hence need for mm pointer deref.
2. In pre-3.12 SMP kernel, the problem triggering vmalloc didn't exist in
pre-userland code path - it was introduced with commit 20bafb3d23d108bc

====================
cdc_ncm: many small and mostly trivial fixes
This series ended up longer than expected, and it is still not
complete. There is more to come when time allows...
Most changes are trivial. Notable non-trivial changes are
- removed filtering of identical speed notifications
- tx_max calulation is changed to count the pad byte if
necessary, and respect the device limit as an absolute
upper limit even if it is too low according to the spec
- remove the bug preventing SET_MAX_DATAGRAM_SIZE from having
any effect
- drop the pad-to-max if ZLPs are enabled
- the driver specific VERSION is dropped
- dev->hard_mtu is set to tx_max instead of max_datagram_size
causing usbnet to calculate the qlen based on the real max
size of tx skbs
This series has been tested, along with the previously posted
cdc_mbim series, on the NCM and MBIM devices I have:
- Ericsson F5521gw (NCM)
- Huawei E367 (MBIM)
- D-Link DWM-156 A7 (MBIM w/ too low dwNtb{In,Out}MaxSize bug)
- Sierra Wireless MC7710 (MBIM w/ ZLP and CDC Union bugs)
Apart from the D-Link modem dropping a lot less oversized
frames with the fix dedicated to it, there are no end user
noticable functional changes as a result of this series. But
all the non-trivial changes I listed above are of course
detectable by users looking at that specific area (except maybe
the removed speed notification, which requires a device sending
duplicates to be noticable - I don't have any such device).

There are MBIM devices out there reporting
dwNtbInMaxSize=2048 dwNtbOutMaxSize=2048
and since the spec require a datagram max size of at least
2048, this means that a full sized datagram will never fit.
Still, sending larger NTBs than the device supports is not
going to help. We do not have any other options than either
a) refusing to bindi, or
b) respect the insanely low value.
Alternative b will at least make these devices work, so go
for it.
