Rolf Neugebauer reported very long delays at netns dismantle.
Eric W. Biederman was kind enough to look at this problem
and noticed synchronize_net() occurring from netif_napi_del() that was
added in linux-4.5
Busy polling makes no sense for tunnels NAPI.
If busy poll is used for sessions over tunnels, the poller will need to
poll the physical device queue anyway.
netif_tx_napi_add() could be used here, but function name is misleading,
and renaming it is not stable material, so set NAPI_STATE_NO_BUSY_POLL
bit directly.
This will avoid inserting gro_cells napi structures in napi_hash[]
and avoid the problematic synchronize_net() (per possible cpu) that
Rolf reported.
Fixes: 93d05d4a320c ("net: provide generic busy polling to all NAPI drivers")

This reverts commit cf00713a655d ("include/uapi/linux/atm_zatm.h: include
linux/time.h").
This attempted to fix userspace breakage that no longer existed when
the patch was merged. Almost one year earlier, commit 70ba07b675b5
("atm: remove 'struct zatm_t_hist'") deleted the struct in question.
After this patch was merged, we now have to deal with people being
unable to include this header in conjunction with standard C library
headers like stdlib.h (which linux-atm does). Example breakage:
x86_64-pc-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I../.. -I./../q2931 -I./../saal \

With syzkaller help, Marco Grassi found a bug in TCP stack,
crashing in tcp_collapse()
Root cause is that sk_filter() can truncate the incoming skb,
but TCP stack was not really expecting this to happen.
It probably was expecting a simple DROP or ACCEPT behavior.
We first need to make sure no part of TCP header could be removed.
Then we need to adjust TCP_SKB_CB(skb)->end_seq
Many thanks to syzkaller team and Marco for giving us a reproducer.

If the bpf program calls bpf_redirect(dev, 0) and dev is
an ipip/ip6tnl, it currently includes the mac header.
e.g. If dev is ipip, the end result is IP-EthHdr-IP instead
of IP-IP.
The fix is to pull the mac header. At ingress, skb_postpull_rcsum()
is not needed because the ethhdr should have been pulled once already
and then got pushed back just before calling the bpf_prog.
At egress, this patch calls skb_postpull_rcsum().
If bpf_redirect(dev, BPF_F_INGRESS) is called,
it also fails now because it calls dev_forward_skb() which
eventually calls eth_type_trans(skb, dev). The eth_type_trans()
will set skb->type = PACKET_OTHERHOST because the mac address
does not match the redirecting dev->dev_addr. The PACKET_OTHERHOST
will eventually cause the ip_rcv() errors out. To fix this,
____dev_forward_skb() is added.
Joint work with Daniel Borkmann.

Netfilter fixes for net
The following patchset contains a larger than usual batch of Netfilter
fixes for your net tree. This series contains a mixture of old bugs and
recently introduced bugs, they are:
1) Fix a crash when using nft_dynset with nft_set_rbtree, which doesn't
support the set element updates from the packet path. From Liping
Zhang.
2) Fix leak when nft_expr_clone() fails, from Liping Zhang.
3) Fix a race when inserting new elements to the set hash from the
packet path, also from Liping.
4) Handle segmented TCP SIP packets properly, basically avoid that the
INVITE in the allow header create bogus expectations by performing
stricter SIP message parsing, from Ulrich Weber.
5) nft_parse_u32_check() should return signed integer for errors, from
John Linville.
6) Fix wrong allocation instead of connlabels, allocate 16 instead of
32 bytes, from Florian Westphal.
7) Fix compilation breakage when building the ip_vs_sync code with
CONFIG_OPTIMIZE_INLINING on x86, from Arnd Bergmann.
8) Destroy the new set if the transaction object cannot be allocated,
also from Liping Zhang.
9) Use device to route duplicated packets via nft_dup only when set by
the user, otherwise packets may not follow the right route, again
from Liping.
10) Fix wrong maximum genetlink attribute definition in IPVS, from
WANG Cong.
11) Ignore untracked conntrack objects from xt_connmark, from Florian
Westphal.
12) Allow to use conntrack helpers that are registered NFPROTO_UNSPEC
via CT target, otherwise we cannot use the h.245 helper, from
Florian.
13) Revisit garbage collection heuristic in the new workqueue-based
timer approach for conntrack to evict objects earlier, again from
Florian.
14) Fix crash in nf_tables when inserting an element into a verdict map,
from Liping Zhang.

This is now a fixed-size extension, so we don't need to pass a variable
alloc size. This (harmless) error results in allocating 32 instead of
the needed 16 bytes for this extension as the size gets passed twice.

nft_parse_u32_check
Commit 36b701fae12ac ("netfilter: nf_tables: validate maximum value of
u32 netlink attributes") introduced nft_parse_u32_check with a return
value of "unsigned int", yet on error it returns "-ERANGE".
This patch corrects the mismatch by changing the return value to "int",
which happens to match the actual users of nft_parse_u32_check already.
Found by Coverity, CID 1373930.
Note that commit 21a9e0f1568ea ("netfilter: nft_exthdr: fix error
handling in nft_exthdr_init()) attempted to address the issue, but
did not address the return type of nft_parse_u32_check.

When nft_expr_clone failed, a series of problems will happen:
1. module refcnt will leak, we call __module_get at the beginning but
we forget to put it back if ops->clone returns fail
2. memory will be leaked, if clone fail, we just return NULL and forget
to free the alloced element
3. set->nelems will become incorrect when set->size is specified. If
clone fail, we should decrease the set->nelems
Now this patch fixes these problems. And fortunately, clone fail will
only happen on counter expression when memory is exhausted.

It turns out DCCP calls __sk_receive_skb(), and this broke when
lookups no longer took a reference on listeners.
Fix this issue by adding a @refcounted parameter to __sk_receive_skb(),
so that sock_put() is used only when needed.

Some configurations (e.g. geneve interface with default
MTU of 1500 over an ethernet interface with 1500 MTU) result
in the transmission of packets that exceed the configured MTU.
While this should be considered to be a "bad" configuration,
it is still allowed and should not result in the sending
of packets that exceed the configured MTU.
Fix by dropping the assumption in ip_finish_output_gso() that
locally originated gso packets will never need fragmentation.
Basic testing using iperf (observing CPU usage and bandwidth)
have shown no measurable performance impact for traffic not
requiring fragmentation.

skb->cb may contain data from previous layers. In the observed scenario,
the garbage data were misinterpreted as IP6CB(skb)->frag_max_size, so
that small packets sent through the tunnel are mistakenly fragmented.
This patch unconditionally clears the control buffer in ip6tunnel_xmit(),
which affects ip6_tunnel, ip6_udp_tunnel and ip6_gre. Currently none of
these tunnels set IP6CB(skb)->flags, otherwise it needs to be done earlier.

Prior to this patch, in rx path, before calling lock_sock, it needed to
hold assoc when got it by __sctp_lookup_association, in case other place
would free/put assoc.
But in __sctp_lookup_association, it lookup and hold transport, then got
assoc by transport->assoc, then hold assoc and put transport. It means
it didn't hold transport, yet it was returned and later on directly
assigned to chunk->transport.
Without the protection of sock lock, the transport may be freed/put by
other places, which would cause a use-after-free issue.
This patch is to fix this issue by holding transport instead of assoc.
As holding transport can make sure to access assoc is also safe, and
actually it looks up assoc by searching transport rhashtable, to hold
transport here makes more sense.
Note that the function will be renamed later on on another patch.

We have a couple of drivers, acpi_apd.c and acpi_lpss.c,
that need to pass extra build-in properties to the devices
they create. Previously the drivers added those properties
to the struct device which is member of the struct
acpi_device, but that does not work. Those properties need
to be assigned to the struct device of the platform device
instead in order for them to become available to the
drivers.
To fix this, this patch changes acpi_create_platform_device
function to take struct property_entry pointer as parameter.

Limit the number of kmemleak false positives by including
.data.ro_after_init in memory scanning. To achieve this we need to add
symbols for start and end of the section to the linker scripts.
The problem was been uncovered by commit 56989f6d8568 ("genetlink: mark
families as __ro_after_init").

This reverts commit 05fd007e4629 ("console: don't prefer first
registered if DT specifies stdout-path").
The reverted commit changes existing behavior on which many ARM boards
rely. Many ARM small-board-computers, like e.g. the Raspberry Pi have
both a video output and a serial console. Depending on whether the user
is using the device as a more regular computer; or as a headless device
we need to have the console on either one or the other.
Many users rely on the kernel behavior of the console being present on
both outputs, before the reverted commit the console setup with no
console= kernel arguments on an ARM board which sets stdout-path in dt
would look like this:
[root@localhost ~]# cat /proc/consoles
ttyS0 -W- (EC p a) 4:64
tty0 -WU (E p ) 4:1
Where as after the reverted commit, it looks like this:
[root@localhost ~]# cat /proc/consoles
ttyS0 -W- (EC p a) 4:64
This commit reverts commit 05fd007e4629 ("console: don't prefer first
registered if DT specifies stdout-path") restoring the original
behavior.

Christian Borntraeger reports:
With commit 8ea1d2a1985a ("mm, frontswap: convert frontswap_enabled to
static key") kmemleak complains about a memory leak in swapon
unreferenced object 0x3e09ba56000 (size 32112640):
comm "swapon", pid 7852, jiffies 4294968787 (age 1490.770s)
hex dump (first 32 bytes):
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
backtrace:

vzalloc+0x58/0x68
SyS_swapon+0xd60/0x12f8
system_call+0xd6/0x270
Turns out kmemleak is right. We now allocate the frontswap map
depending on the kernel config (and no longer on the enablement)
swapfile.c:
[...]
if (IS_ENABLED(CONFIG_FRONTSWAP))
frontswap_map = vzalloc(BITS_TO_LONGS(maxpages) * sizeof(long));
but later on this is passed along
--> enable_swap_info(p, prio, swap_map, cluster_info, frontswap_map);
and ignored if frontswap is disabled
--> frontswap_init(p->type, frontswap_map);
static inline void frontswap_init(unsigned type, unsigned long *map)
{
if (frontswap_enabled())
__frontswap_init(type, map);
}
Thing is, that frontswap map is never freed.
The leakage is relatively not that bad, because swapon is an infrequent
and privileged operation. However, if the first frontswap backend is
registered after a swap type has been already enabled, it will WARN_ON
in frontswap_register_ops() and frontswap will not be available for the
swap type.
Fix this by making sure the map is assigned by frontswap_init() as long
as CONFIG_FRONTSWAP is enabled.

Currently we dropped freeze protection of aio writes just after IO was
submitted. Thus aio write could be in flight while the filesystem was
frozen and that could result in unexpected situation like aio completion
wanting to convert extent type on frozen filesystem. Testcase from
Dmitry triggering this is like:
for ((i=0;i<60;i++));do fsfreeze -f /mnt ;sleep 1;fsfreeze -u /mnt;done &
fio --bs=4k --ioengine=libaio --iodepth=128 --size=1g --direct=1 \
--runtime=60 --filename=/mnt/file --name=rand-write --rw=randwrite
Fix the problem by dropping freeze protection only once IO is completed
in aio_complete().

osdc->last_linger_id is a counter for lreq->linger_id, which is used
for watch cookies. Starting with a large integer should ease the task
of telling apart kernel and userspace clients.

We had inserted a #error into the topology UAPI code to ensure that the
ABI was not adopted by userspace while final review and testing was
ongoing. The idea was that some finishing touches would be made to the
ABI before declaring it stable and suitable for use in production but
this has not yet happened as more than a year later revisions to the ABI
are still onging.
The reality however is that people are shipping topology files in
production and these ABI changes are causing practical issues for users
and we can't break userspace. This makes this error pointless so we
should remove it.

Commit 345ddcc882d8 ("ftrace: Have set_ftrace_pid use the bitmap like
events do") added a couple of this_cpu_read calls to the ftrace code.
On x86 this is not a problem, since it has single instructions to read
percpu data. Other architectures which use the generic variant now
have additional preempt_disable and preempt_enable calls in the core
ftrace code. This may lead to recursive calls and in result to a dead
machine, e.g. if preemption and debugging options are enabled.
To fix this use the notrace variant of preempt_disable and
preempt_enable within the generic percpu code.

When changing from one data interface setting to another, one has to
ensure a specific sequence which is described in the ONFI spec.
One of these constraints is that the CE line has go high after a reset
before a command can be sent with the new data interface setting, which
is not guaranteed by the current implementation.
Rework the nand_reset() function and all the call sites to make sure the
CE line is asserted and released when required.
Also make sure to actually apply the new data interface setting on the
first die.

We don't want all planes to be added to the state whenever a
plane with fixed zpos gets enabled/disabled. This is true
especially for eg. cursor planes on i915, as we want cursor
updates to go through w/o throttling. Same holds for drivers
that don't support zpos at all (i915 actually falls into this
category right now since we've not yet added zpos support).
Allow drivers more freedom by letting them deal with zpos
themselves instead of doing it in drm_atomic_helper_check_planes()
unconditionally. Let's just inline the required calls into all
the driver that currently depend on this.
v2: Inline the stuff into the drivers instead of adding another
helper, document things better (Daniel)

Make include/linux/regmap.h include <linux/delay.h>, like

When vxlan device is closed vxlan socket is freed. This
operation can race with vxlan-xmit function which
dereferences vxlan socket. Following patch uses RCU
mechanism to avoid this situation.

Currently interrupt test that is part of ethtool selftest runs the
check over all interrupt vectors of the device.
In mlx4_en package part of interrupt vectors are uninitialized since
mlx4_ib doesn't exist. This causes NOP FW command to time out.
Change logic to test current port interrupt vectors only.

Johannes Berg says:
====================
Just two fixes:
* a fix to process all events while suspending, so any
potential calls into the driver are done before it is
suspended
* small markup fixes for the sphinx documentation conversion
that's coming into the tree via the doc tree

This reverts commit e3f74b841d48
("hv_netvsc: report vmbus name in ethtool")'
because of problem introduced by commit f9a56e5d6a0ba
("Drivers: hv: make VMBus bus ids persistent").
This changed the format of the vmbus name and this new format is too
long to fit in the bus_info field of ethtool.
