commit b1cb7372fa822af6c06c8045963571d13ad6348b upstream.
dvb_frontend_invoke_release() may free the frontend struct.
So, the free logic can't update it anymore after calling it.
That's OK, as __dvb_frontend_free() is called only when the
krefs are zeroed, so nobody is using it anymore.
That should fix the following KASAN error:
The KASAN report looks like this (running on kernel 3e0cc09a3a2c40ec1ffb6b4e12da86e98feccb11 (4.14-rc5+)):

commit 62229de19ff2b7f3e0ebf4d48ad99061127d0281 upstream.
Follow-up to: ead666000a5f ("media: dvb_frontend: only use kref after initialized")
The aforementioned commit fixed refcount OOPSes when demod driver attaching
succeeded but tuner driver didn't. However, the use count of the attached
demod drivers don't go back to zero and thus couldn't be cleanly unloaded.
Improve on this by calling dvb_frontend_invoke_release() in
__dvb_frontend_free() regardless of fepriv being NULL, instead of returning
when fepriv is NULL. This is safe to do since _invoke_release() will check
for passed pointers being valid before calling the .release() function.
[mchehab@s-opensource.com: changed the logic a little bit to reduce
conflicts with another bug fix patch under review]

Requesting a sync on an active raid device via a table reload
(see 'sync' parameter in Documentation/device-mapper/dm-raid.txt)
skips the super_load() call that defines the superblock size
(rdev->sb_size) -- resulting in an oops if/when super_sync()->memset()
is called.
Fix by moving the initialization of the superblock start and size
out of super_load() to the caller (analyse_superblocks).

A NULL deref happens when nvmet_rdma_remove_one() is called more than once
(e.g. while connected via 2 ports).
The first call frees the queues related to the first ib_device but
doesn't remove them from the queue list.
While calling nvmet_rdma_remove_one() for the second ib_device it goes over
the full queue list again and we get the NULL deref.

[ Upstream commit 8d4e10e9ed9450e18fbbf6a8872be0eac9fd4999 ]
On PowerNV platforms, firmware provides exit latency and
target residency for each of the idle states in nano
seconds. Cpuidle framework expects the values in micro
seconds. Round up to nearest micro seconds to avoid errors
in cases where the values are defined as fractional micro
seconds.
Default idle state of 'snooze' has exit latency of zero. If
other states have fractional micro second exit latency, they
would get rounded down to zero micro second and make cpuidle
framework choose deeper idle state when snooze loop is the
right choice.

commit 4f7f5551a760eb0124267be65763008169db7087 upstream.
System may crash after unloading ipmi_si.ko module
because a timer may remain and fire after the module cleaned up resources.
cleanup_one_si() contains the following processing.
/*
* Make sure that interrupts, the timer and the thread are
* stopped and will not run again.
*/
if (to_clean->irq_cleanup)
to_clean->irq_cleanup(to_clean);
wait_for_timer_and_thread(to_clean);
/*
* Timeouts are stopped, now make sure the interrupts are off
* in the BMC. Note that timers and CPU interrupts are off,
* so no need for locks.
*/
while (to_clean->curr_msg || (to_clean->si_state != SI_NORMAL)) {
poll(to_clean);
schedule_timeout_uninterruptible(1);
}
si_state changes as following in the while loop calling poll(to_clean).
SI_GETTING_MESSAGES
=> SI_CHECKING_ENABLES
=> SI_SETTING_ENABLES
=> SI_GETTING_EVENTS
=> SI_NORMAL
As written in the code comments above,
timers are expected to stop before the polling loop and not to run again.
But the timer is set again in the following process
when si_state becomes SI_SETTING_ENABLES.
=> poll
=> smi_event_handler
=> handle_transaction_done
// smi_info->si_state == SI_SETTING_ENABLES
=> start_getting_events
=> start_new_msg
=> smi_mod_timer
=> mod_timer
As a result, before the timer set in start_new_msg() expires,
the polling loop may see si_state becoming SI_NORMAL
and the module clean-up finishes.
For example, hard LOCKUP and panic occurred as following.
smi_timeout was called after smi_event_handler,
kcs_event and hangs at port_inb()
trying to access I/O port after release.

[ Upstream commit 0c19f846d582af919db66a5914a0189f9f92c936 ]
Tuntap and similar devices can inject GSO packets. Accept type
VIRTIO_NET_HDR_GSO_UDP, even though not generating UFO natively.
Processes are expected to use feature negotiation such as TUNSETOFFLOAD
to detect supported offload types and refrain from injecting other
packets. This process breaks down with live migration: guest kernels
do not renegotiate flags, so destination hosts need to expose all
features that the source host does.
Partially revert the UFO removal from 182e0b6b5846~1..d9d30adf5677.
This patch introduces nearly(*) no new code to simplify verification.
It brings back verbatim tuntap UFO negotiation, VIRTIO_NET_HDR_GSO_UDP
insertion and software UFO segmentation.
It does not reinstate protocol stack support, hardware offload
(NETIF_F_UFO), SKB_GSO_UDP tunneling in SKB_GSO_SOFTWARE or reception
of VIRTIO_NET_HDR_GSO_UDP packets in tuntap.
To support SKB_GSO_UDP reappearing in the stack, also reinstate
logic in act_csum and openvswitch. Achieve equivalence with v4.13 HEAD
by squashing in commit 939912216fa8 ("net: skb_needs_check() removes
CHECKSUM_UNNECESSARY check for tx.") and reverting commit 8d63bee643f1
("net: avoid skb_warn_bad_offload false positives on UFO").
(*) To avoid having to bring back skb_shinfo(skb)->ip6_frag_id,
ipv6_proxy_select_ident is changed to return a __be32 and this is
assigned directly to the frag_hdr. Also, SKB_GSO_UDP is inserted
at the end of the enum to minimize code churn.
Tested
Booted a v4.13 guest kernel with QEMU. On a host kernel before this
patch `ethtool -k eth0` shows UFO disabled. After the patch, it is
enabled, same as on a v4.13 host kernel.
A UFO packet sent from the guest appears on the tap device:
host:
nc -l -p -u 8000 &
tcpdump -n -i tap0
guest:
dd if=/dev/zero of=payload.txt bs=1 count=2000
nc -u 192.16.1.1 8000 < payload.txt
Direct tap to tap transmission of VIRTIO_NET_HDR_GSO_UDP succeeds,
packets arriving fragmented:
./with_tap_pair.sh ./tap_send_ufo tap0 tap1
(from https://github.com/wdebruij/kerneltools/tree/master/tests)
Changes

[ Upstream commit 6d69b1f1eb7a2edf8a3547f361c61f2538e054bb ]
Using GSO with small MTUs currently results in a substantial throughput
regression - which is caused by how qeth needs to map non-linear skbs
into its IO buffer elements:
compared to a linear skb, each GSO-segmented skb effectively consumes
twice as many buffer elements (ie two instead of one) due to the
additional header-only part. This causes the Output Queue to be
congested with low-utilized IO buffers.
Fix this as follows:
If the MSS is low enough so that a non-SG GSO segmentation produces
order-0 skbs (currently ~3500 byte), opt out from NETIF_F_SG. This is
where we anticipate the biggest savings, since an SG-enabled
GSO segmentation produces skbs that always consume at least two
buffer elements.
Larger MSS values continue to get a SG-enabled GSO segmentation, since
1) the relative overhead of the additional header-only buffer element
becomes less noticeable, and
2) the linearization overhead increases.
With the throughput regression fixed, re-enable NETIF_F_SG by default to
reap the significant CPU savings of GSO.

[ Upsteam commit bc3ab70584696cb798b9e1e0ac8e6ced5fd4c3b8 ]
Commit 5f78e29ceebf ("qeth: optimize IP handling in rx_mode callback")
reworked how secondary addresses are managed for qeth devices.
Instead of dropping & subsequently re-adding all addresses on every
ndo_set_rx_mode() call, qeth now keeps track of the addresses that are
currently registered with the HW.
On a ndo_set_rx_mode(), we thus only need to do (de-)registration
requests for the addresses that have actually changed.
On L3 devices, the lookup for IPv4 Multicast addresses checks the wrong
hashtable - and thus never finds a match. As a result, we first delete
*all* such addresses, and then re-add them again. So each set_rx_mode()
causes a short period where the IPv4 Multicast addresses are not
registered, and the card stops forwarding inbound traffic for them.
Fix this by setting the ->is_multicast flag on the lookup object, thus
enabling qeth_l3_ip_from_hash() to search the correct hashtable and
find a match there.

The mss variable tracks the last max segment size sent to the TSO
engine. We do not update the hardware as long as we receive skb:s with
the same value in gso_size.
During a network device down/up cycle (mapped to stmmac_release() and
stmmac_open() callbacks) we issue a reset to the hardware and it
forgets the setting for mss. However we did not zero out our mss
variable so the next transmission of a gso packet happens with an
undefined hardware setting.
This triggers a hang in the TSO engine and eventuelly the netdev
watchdog will bark.

[ Upstream commit 6e474083f3daf3a3546737f5d7d502ad12eb257c ]
Matthew found a roughly 40% tcp throughput regression with commit
c67df11f(vhost_net: try batch dequing from skb array) as discussed
in the following thread:
https://www.mail-archive.com/netdev@vger.kernel.org/msg187936.html
Eventually we figured out that it was a skb leak in handle_rx()
when sending packets to the VM. This usually happens when a guest
can not drain out vq as fast as vhost fills in, afterwards it sets
off the traffic jam and leaks skb(s) which occurs as no headcount
to send on the vq from vhost side.
This can be avoided by making sure we have got enough headcount
before actually consuming a skb from the batched rx array while
transmitting, which is simply done by moving checking the zero
headcount a bit ahead.

Make sure to search only the child nodes of "/clocks", rather than the
whole device-tree depth-first starting at "/clocks" when determining
whether to register a fixed clock in the legacy board-clock registration

i2c1 and i2c2 bits for CCU are not bit 0 but bit 1 and bit 2.
Because of that, the i2c0 (bit 0) was not correctly configured.
Fixed the correct bits for i2c1 and i2c2.

geneve->sock4/6 were added with geneve_open and released with geneve_stop.
So when geneve link down, we will not able to show remote address and
checksum info after commit 11387fe4a98 ("geneve: fix fill_info when using
collect_metadata").
Fix this by avoid passing *_REMOTE{,6} for COLLECT_METADATA since they are
mutually exclusive, and always show UDP_ZERO_CSUM6_RX info.

[ Upstream commit 6c3ab204f4ca00374a374bc0fc9a275b64d1bcbb ]
Hardware has no notion of new or last mask id, instead it makes use of the
message type (i.e. add flow or del flow) in combination with a single bit
in metadata flags to determine when to add or delete a mask id. Previously
we made use of the new or last flags to indicate that a new mask should be
allocated or deallocated, respectively. This incorrect behaviour is fixed
by making use single bit in metadata flags to indicate mask allocation or
deallocation.

In the cases where len is too long, the error return path fails to
kfree allocated buffers buf and usb_reg_buf. The simplest fix is to
perform the sanity check on len before the allocations to avoid having
to do the kfree'ing in the first place.

commit 315d160c5a4e034a576a13aa21e7235d5c9ec609 upstream.
For now the only LSM security enforcement mechanism available is
specific to InfiniBand. Bypass enforcement for non-IB link types.
This fixes a regression where modify_qp fails for iWARP because
querying the PKEY returns -EINVAL.
