The failure path in ibmvnic_open() mistakenly makes a second call
to napi_enable instead of calling napi_disable. This can result
in a BUG_ON for any queues that were enabled in the previous call
to napi_enable.

Initialize condition variables prior to invoking any work that can

1) If the timing is wrong we can indefinitely stop generating new ipv6
temporary addresses, from Marcus Huewe.
2) Don't double free per-cpu stats in ipv6 SIT tunnel driver, from Cong

3) Put protections in place so that AF_PACKET is not able to submit

4) Fix memory leaks in ipv4 and ipv6 multicast code, from Hangbin Liu.
5) Don't use udp_ioctl() in l2tp code, UDP version expects a UDP socket

- The powernv CPU hotplug code was missing a wakeup type and failing to flush

If a USB-to-serial adapter is unplugged, the driver re-initializes, with
dev->hard_header_len and dev->addr_len set to zero, instead of the correct
values. If then a packet is sent through the half-dead interface, the
kernel will panic due to running out of headroom in the skb when pushing
for the AX.25 headers resulting in this panic:

This patch makes mkiss behave like the 6pack driver. 6pack does not
panic. In 6pack.c sp_setup() (same function name here) the values for
dev->hard_header_len and dev->addr_len are set to the same values as in

This fixes a crash when running out of grant refs when creating many
queues across many netdevs.
* If creating queues fails (i.e. there are no grant refs available),
call xenbus_dev_fatal() to ensure that the xenbus device is set to the
closed state.
* If no queues are created, don't call xennet_disconnect_backend as
netdev->real_num_tx_queues will not have been set correctly.
* If setup_netfront() fails, ensure that all the queues created are
cleaned up, not just those that have been set up.
* If any queues were set up and an error occurs, call
xennet_destroy_queues() to clean up the napi context.
* If any fatal error occurs, unregister and destroy the netdev to avoid
leaving around a half setup network device.

If a context is configured as dualstack ("IPv4v6"), the modem indicates
the context activation with a slightly different indication message.
The dual-stack indication omits the link_type (IPv4/v6) and adds
additional address fields.
IPv6 LSIs are identical to IPv4 LSIs, but have a different link type.

The commit 90c311b0ee ("xen-netfront: Fix Rx stall during network

all invocations of xennet_alloc_rx_buffers for certain workloads.
This reworks the fix by reverting to the old behaviour and taking into
consideration the skb allocation failure. Refill timer is now triggered
on insufficient requests or skb allocation failure.

Pull SCSI target fixes from Nicholas Bellinger:
"This target series for v4.10 contains fixes which address a few
long-standing bugs that DATERA's QA + automation teams have uncovered
while putting v4.1.y target code into production usage.
We've been running the top three in our nightly automated regression
runs for the last two months, and the COMPARE_AND_WRITE fix Mr. Gary
Guo has been manually verifying against a four node ESX cluster this
past week.
Note all of them have CC' stable tags.
Summary:
- Fix a bug with ESX EXTENDED_COPY + SAM_STAT_RESERVATION_CONFLICT
status, where target_core_xcopy.c logic was incorrectly returning
SAM_STAT_CHECK_CONDITION for all non SAM_STAT_GOOD cases (Nixon
Vincent)
- Fix a TMR LUN_RESET hung task bug while other in-flight TMRs are
being aborted, before the new one had been dispatched into tmr_wq
(Rob Millner)
- Fix a long standing double free OOPs, where a dynamically generated
'demo-mode' NodeACL has multiple sessions associated with it, and
the /sys/kernel/config/target/$FABRIC/$WWN/ subsequently disables
demo-mode, but never converts the dynamic ACL into a explicit ACL
(Rob Millner)
- Fix a long standing reference leak with ESX VAAI COMPARE_AND_WRITE
when the second phase WRITE COMMIT command fails, resulting in
CHECK_CONDITION response never being sent and se_cmd->cmd_kref
never reaching zero (Gary Guo)
Beyond these items on v4.1.y we've reproduced, fixed, and run through
our regression test suite using iscsi-target exports, there are two
additional outstanding list items:
- Remove a >= v4.2 RCU conversion BUG_ON that would trigger when
dynamic node NodeACLs where being converted to explicit NodeACLs.
The patch drops the BUG_ON to follow how pre RCU conversion worked
for this special case (Benjamin Estrabaud)
- Add ibmvscsis target_core_fabric_ops->max_data_sg_nent assignment
to match what IBM's Virtual SCSI hypervisor is already enforcing at
transport layer. (Bryant Ly + Steven Royer)"
* git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending:
ibmvscsis: Add SGL limit
target: Fix COMPARE_AND_WRITE ref leak for non GOOD status
target: Fix multi-session dynamic se_node_acl double free OOPs

target: Don't BUG_ON during NodeACL dynamic -> explicit conversion
The Generic PHY drivers gets assigned after we checked that the current
PHY driver is NULL, so we need to check a few things before we can
safely dereference d->driver. This would be causing a NULL deference to
occur when a system binds to the Generic PHY driver. Update
phy_attach_direct() to do the following:
- grab the driver module reference after we have assigned the Generic
PHY drivers accordingly, and remember we came from the generic PHY
path
- update the error path to clean up the module reference in case the
Generic PHY probe function fails
- split the error path involving phy_detacht() to avoid double free/put
since phy_detach() does all the clean up
- finally, have phy_detach() drop the module reference count before we
call device_release_driver() for the Generic PHY driver case

https://bugzilla.kernel.org/show_bug.cgi?id=177551.
Bail out early from init_cache_random_seq if s->random_seq is already
initialised. This prevents destroying the previously computed
random_seq offsets later in the function.
If the offsets are destroyed, then shuffle_freelist will truncate
page->freelist to just the first object (orphaning the rest).

Commit 513e3d2d11 ("cpumask: always use nr_cpu_ids in formatting and
parsing functions") converted both cpumask printing and parsing
functions to use nr_cpu_ids instead of nr_cpumask_bits. While this was
okay for the printing functions as it just picked one of the two output
formats that we were alternating between depending on a kernel config,
doing the same for parsing wasn't okay.
nr_cpumask_bits can be either nr_cpu_ids or NR_CPUS. We can always use
nr_cpu_ids but that is a variable while NR_CPUS is a constant, so it can
be more efficient to use NR_CPUS when we can get away with it.
Converting the printing functions to nr_cpu_ids makes sense because it
affects how the masks get presented to userspace and doesn't break
anything; however, using nr_cpu_ids for parsing functions can
incorrectly leave the higher bits uninitialized while reading in these
masks from userland. As all testing and comparison functions use
nr_cpumask_bits which can be larger than nr_cpu_ids, the parsed cpumasks
can erroneously yield false negative results.
This made the taskstats interface incorrectly return -EINVAL even when
the inputs were correct.
Fix it by restoring the parse functions to use nr_cpumask_bits instead
of nr_cpu_ids.

Some ->page_mkwrite handlers may return VM_FAULT_RETRY as its return
code (GFS2 or Lustre can definitely do this). However VM_FAULT_RETRY
from ->page_mkwrite is completely unhandled by the mm code and results
in locking and writeably mapping the page which definitely is not what
the caller wanted.
Fix Lustre and block_page_mkwrite_ret() used by other filesystems
(notably GFS2) to return VM_FAULT_NOPAGE instead which results in
bailing out from the fault code, the CPU then retries the access, and we
fault again effectively doing what the handler wanted.

When drm_crtc_init_with_planes() was orignally added
(in drm_crtc.c, e13161af80
drm: Add drm_crtc_init_with_planes() (v2)), it only checked for "primary"
being non-null. If that was the case, it modified primary->possible_crtcs.
Then, when support for cursor planes was added
(fc1d3e44ef drm: Allow drivers to register
cursor planes with crtc), the same behaviour was implemented for cursor
planes.
vc4_plane_init() since its inception has passed 0xff as "possible_crtcs"
parameter to drm_universal_plane_init(). With a change in drm_crtc.c
(7abc7d4751 drm: don't override
possible_crtcs for primary/cursor planes) passing 0xff results in primary's
possible_crtcs set to 0xff (cursor was updated manually by vc4_crtc.c).
Consequently, it would be allowed to use the primary plane from CRTC 1 (for
example) on CRTC 0, which would result in the overlay and cursors being
buried.
