Subject: [PATCH 768/826] scsi: fcoe: Embed fc_rport_priv in fcoe_rport
structure
commit 023358b136d490ca91735ac6490db3741af5a8bd upstream.
Gcc-9 complains for a memset across pointer boundaries, which happens as
the code tries to allocate a flexible array on the stack. Turns out we
cannot do this without relying on gcc-isms, so with this patch we'll embed
the fc_rport_priv structure into fcoe_rport, can use the normal
'container_of' outcast, and will only have to do a memset over one
structure.

Subject: [PATCH 769/826] gcc-9: don't warn about uninitialized variable
commit cf676908846a06443fa5e6724ca3f5dd7460eca1 upstream.
I'm not sure what made gcc warn about this code now. The 'ret' variable
does end up initialized in all cases, but it's definitely not obvious,
so the compiler is quite reasonable to warn about this.
So just add initialization to make it all much more obvious both to
compilers and to humans.

Subject: [PATCH 770/826] driver core: Establish order of operations for
device_add and device_del via bitflag
commit 3451a495ef244a88ed6317a035299d835554d579 upstream.
Add an additional bit flag to the device_private struct named "dead".
This additional flag provides a guarantee that when a device_del is
executed on a given interface an async worker will not attempt to attach
the driver following the earlier device_del call. Previously this
guarantee was not present and could result in the device_del call
attempting to remove a driver from an interface only to have the async
worker attempt to probe the driver later when it finally completes the
asynchronous probe call.
One additional change added was that I pulled the check for dev->driver
out of the __device_attach_driver call and instead placed it in the
__device_attach_async_helper call. This was motivated by the fact that the
only other caller of this, __device_attach, had already taken the
device_lock() and checked for dev->driver. Instead of testing for this
twice in this path it makes more sense to just consolidate the dev->dead
and dev->driver checks together into one set of checks.

Subject: [PATCH 771/826] drivers/base: Introduce kill_device()
commit 00289cd87676e14913d2d8492d1ce05c4baafdae upstream.
The libnvdimm subsystem arranges for devices to be destroyed as a result
of a sysfs operation. Since device_unregister() cannot be called from
an actively running sysfs attribute of the same device libnvdimm
arranges for device_unregister() to be performed in an out-of-line async
context.
The driver core maintains a 'dead' state for coordinating its own racing
async registration / de-registration requests. Rather than add local
'dead' state tracking infrastructure to libnvdimm device objects, export
the existing state tracking via a new kill_device() helper.
The kill_device() helper simply marks the device as dead, i.e. that it
is on its way to device_del(), or returns that the device was already
dead. This can be used in advance of calling device_unregister() for
subsystems like libnvdimm that might need to handle multiple user
threads racing to delete a device.
This refactoring does not change any behavior, but it is a pre-requisite
for follow-on fixes and therefore marked for -stable.

Subject: [PATCH 773/826] libnvdimm/region: Register badblocks before
namespaces
commit 700cd033a82d466ad8f9615f9985525e45f8960a upstream.
Namespace activation expects to be able to reference region badblocks.
The following warning sometimes triggers when asynchronous namespace
activation races in front of the completion of namespace probing. Move
all possible namespace probing after region badblocks initialization.
Otherwise, lockdep sometimes catches the uninitialized state of the
badblocks seqlock with stack trace signatures like:
INFO: trying to register non-static key.
pmem2: detected capacity change from 0 to 136365211648
the code is fine but needs lockdep annotation.
turning off the locking correctness validator.

Subject: [PATCH 774/826] libnvdimm/bus: Prepare the nd_ioctl() path to be
re-entrant
commit 6de5d06e657acdbcf9637dac37916a4a5309e0f4 upstream.
In preparation for not holding a lock over the execution of nd_ioctl(),
update the implementation to allow multiple threads to be attempting
ioctls at the same time. The bus lock still prevents multiple in-flight
->ndctl() invocations from corrupting each other's state, but static
global staging buffers are moved to the heap.

In this sequence an 'nd_dax' device is being probed and trying to take
the lock on its backing namespace to validate that the 'nd_dax' device
indeed has exclusive access to the backing namespace. Meanwhile, another
thread is trying to update the uuid property of that same backing
namespace. So one thread is in the probe path trying to acquire the
lock, and the other thread has acquired the lock and tries to flush the
probe path.
Fix this deadlock by not holding the namespace device_lock over the
wait_nvdimm_bus_probe_idle() synchronization step. In turn this requires
the device_lock to be held on entry to wait_nvdimm_bus_probe_idle() and
subsequently dropped internally to wait_nvdimm_bus_probe_idle().

Subject: [PATCH 777/826] HID: Add quirk for HP X1200 PIXART OEM mouse
commit 49869d2ea9eecc105a10724c1abf035151a3c4e2 upstream.
The PixArt OEM mice are known for disconnecting every minute in
runlevel 1 or 3 if they are not always polled. So add quirk
ALWAYS_POLL for this one as well.
Jonathan Teh (@jonathan-teh) reported and tested the quirk.

Subject: [PATCH 778/826] IB: directly cast the sockaddr union to aockaddr
Like commit 641114d2af31 ("RDMA: Directly cast the sockaddr union to
sockaddr") we need to quiet gcc 9 from warning about this crazy union.
That commit did not fix all of the warnings in 4.19 and older kernels
because the logic in roce_resolve_route_from_path() was rewritten
between 4.19 and 5.2 when that change happened.

Subject: [PATCH 779/826] atm: iphase: Fix Spectre v1 vulnerability
[ Upstream commit ea443e5e98b5b74e317ef3d26bcaea54931ccdee ]
board is controlled by user-space, hence leading to a potential
exploitation of the Spectre variant 1 vulnerability.
This issue was detected with the help of Smatch:
drivers/atm/iphase.c:2765 ia_ioctl() warn: potential spectre issue 'ia_dev' [r] (local cap)
drivers/atm/iphase.c:2774 ia_ioctl() warn: possible spectre second half. 'iadev'
drivers/atm/iphase.c:2782 ia_ioctl() warn: possible spectre second half. 'iadev'
drivers/atm/iphase.c:2816 ia_ioctl() warn: possible spectre second half. 'iadev'
drivers/atm/iphase.c:2823 ia_ioctl() warn: possible spectre second half. 'iadev'
drivers/atm/iphase.c:2830 ia_ioctl() warn: potential spectre issue '_ia_dev' [r] (local cap)
drivers/atm/iphase.c:2845 ia_ioctl() warn: possible spectre second half. 'iadev'
drivers/atm/iphase.c:2856 ia_ioctl() warn: possible spectre second half. 'iadev'
Fix this by sanitizing board before using it to index ia_dev and _ia_dev
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

[ Upstream commit 944a83a2669ae8aa2c7664e79376ca7468eb0a2b ]
mvpp2 uses a delayed workqueue to gather traffic statistics.
On module removal the workqueue can be destroyed before calling
cancel_delayed_work_sync() on its works.
Fix it by moving the destroy_workqueue() call after mvpp2_port_remove().
Also remove an unneeded call to flush_workqueue()

[ Upstream commit 230bd958c2c846ee292aa38bc6b006296c24ca01 ]
The MTU change code can call napi_disable() with the device already down,
leading to a deadlock. Also, lot of code is duplicated unnecessarily.
Rework mvpp2_change_mtu() to avoid the deadlock and remove duplicated code.

Subject: [PATCH 788/826] net: bridge: delete local fdb on device init failure
[ Upstream commit d7bae09fa008c6c9a489580db0a5a12063b97f97 ]
On initialization failure we have to delete the local fdb which was
inserted due to the default pvid creation. This problem has been present
since the inception of default_pvid. Note that currently there are 2 cases:
1) in br_dev_init() when br_multicast_init() fails
2) if register_netdevice() fails after calling ndo_init()
This patch takes care of both since br_vlan_flush() is called on both
occasions. Also the new fdb delete would be a no-op on normal bridge
device destruction since the local fdb would've been already flushed by
br_dev_delete(). This is not an issue for ports since nbp_vlan_init() is
called last when adding a port thus nothing can fail after it.

Subject: [PATCH 789/826] net: bridge: mcast: don't delete permanent entries
when fast leave is enabled
[ Upstream commit 5c725b6b65067909548ac9ca9bc777098ec9883d ]
When permanent entries were introduced by the commit below, they were
exempt from timing out and thus igmp leave wouldn't affect them unless
fast leave was enabled on the port which was added before permanent
entries existed. It shouldn't matter if fast leave is enabled or not
if the user added a permanent entry it shouldn't be deleted on igmp
leave.
Before:
$ echo 1 > /sys/class/net/eth4/brport/multicast_fast_leave
$ bridge mdb add dev br0 port eth4 grp 229.1.1.1 permanent
$ bridge mdb show
dev br0 port eth4 grp 229.1.1.1 permanent
< join and leave 229.1.1.1 on eth4 >
$ bridge mdb show
$
After:
$ echo 1 > /sys/class/net/eth4/brport/multicast_fast_leave
$ bridge mdb add dev br0 port eth4 grp 229.1.1.1 permanent
$ bridge mdb show
dev br0 port eth4 grp 229.1.1.1 permanent
< join and leave 229.1.1.1 on eth4 >

dev br0 port eth4 grp 229.1.1.1 permanent

Subject: [PATCH 790/826] net: fix ifindex collision during namespace removal
[ Upstream commit 55b40dbf0e76b4bfb9d8b3a16a0208640a9a45df ]
Commit aca51397d014 ("netns: Fix arbitrary net_device-s corruptions
on net_ns stop.") introduced a possibility to hit a BUG in case device
is returning back to init_net and two following conditions are met:
1) dev->ifindex value is used in a name of another "dev%d"
device in init_net.
2) dev->name is used by another device in init_net.
Under real life circumstances this is hard to get. Therefore this has
been present happily for over 10 years. To reproduce:

Fix this by checking if a device with the same name exists in init_net
and fallback to original code - dev%d to allocate name - in case it does.

Subject: [PATCH 791/826] net/mlx5e: always initialize frag->last_in_page
[ Upstream commit 60d60c8fbd8d1acf25b041ecd72ae4fa16e9405b ]
The commit 069d11465a80 ("net/mlx5e: RX, Enhance legacy Receive Queue
memory scheme") introduced an undefined behaviour below due to
"frag->last_in_page" is only initialized in mlx5e_init_frags_partition()
when,
if (next_frag.offset + frag_info[f].frag_stride > PAGE_SIZE)
or after bailed out the loop,
for (i = 0; i < mlx5_wq_cyc_get_size(&rq->wqe.wq); i++)
As the result, there could be some "frag" have uninitialized
value of "last_in_page".
Later, get_frag() obtains those "frag" and check "frag->last_in_page" in
mlx5e_put_rx_frag() and triggers the error during boot. Fix it by always
initializing "frag->last_in_page" to "false" in
mlx5e_init_frags_partition().

Subject: [PATCH 792/826] net/mlx5: Use reversed order when unregister devices
[ Upstream commit 08aa5e7da6bce1a1963f63cf32c2e7ad434ad578 ]
When lag is active, which is controlled by the bonded mlx5e netdev, mlx5
interface unregestering must happen in the reverse order where rdma is
unregistered (unloaded) first, to guarantee all references to the lag
context in hardware is removed, then remove mlx5e netdev interface which
will cleanup the lag context from hardware.
Without this fix during destroy of LAG interface, we observed following
errors:
* mlx5_cmd_check:752:(pid 12556): DESTROY_LAG(0x843) op_mod(0x0) failed,
status bad parameter(0x3), syndrome (0xe4ac33)
* mlx5_cmd_check:752:(pid 12556): DESTROY_LAG(0x843) op_mod(0x0) failed,
status bad parameter(0x3), syndrome (0xa5aee8).

Subject: [PATCH 793/826] net: phylink: Fix flow control for fixed-link
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
[ Upstream commit 8aace4f3eba2a3ceb431e18683ea0e1ecbade5cd ]
In phylink_parse_fixedlink() the pl->link_config.advertising bits are AND
with pl->supported, pl->supported is zeroed and only the speed/duplex
modes and MII bits are set.
So pl->link_config.advertising always loses the flow control/pause bits.
By setting Pause and Asym_Pause bits in pl->supported, the flow control
work again when devicetree "pause" is set in fixes-link node and the MAC
advertise that is supports pause.
Results with this patch.
Legend:
- DT = 'Pause' is set in the fixed-link in devicetree.
- validate() = ‘Yes’ means phylink_set(mask, Pause) is set in the
validate().
- flow = results reported my link is Up line.

offload logic
[ Upstream commit a7cf3d24ee6081930feb4c830a7f6f16ebe31c49 ]
The udp_ip4_ind bit is set only for IPv4 UDP non-fragmented packets
so that the hardware can flip the checksum to 0xFFFF if the computed
checksum is 0 per RFC768.
However, this bit had to be set for IPv6 UDP non fragmented packets
as well per hardware requirements. Otherwise, IPv6 UDP packets
with computed checksum as 0 were transmitted by hardware and were
dropped in the network.
In addition to setting this bit for IPv6 UDP, the field is also
appropriately renamed to udp_ind as part of this change.

Subject: [PATCH 795/826] net: sched: Fix a possible null-pointer dereference
in dequeue_func()
[ Upstream commit 051c7b39be4a91f6b7d8c4548444e4b850f1f56c ]
In dequeue_func(), there is an if statement on line 74 to check whether
skb is NULL:
if (skb)
When skb is NULL, it is used on line 77:
prefetch(&skb->end);
Thus, a possible null-pointer dereference may occur.
To fix this bug, skb->end is used when skb is not NULL.
This bug is found by a static analysis tool STCheck written by us.

Subject: [PATCH 797/826] net: sched: use temporary variable for actions
indexes
[ Upstream commit 7be8ef2cdbfe41a2e524b7c6cc3f8e6cfaa906e4 ]
Currently init call of all actions (except ipt) init their 'parm'
structure as a direct pointer to nla data in skb. This leads to race
condition when some of the filter actions were initialized successfully
(and were assigned with idr action index that was written directly
into nla data), but then were deleted and retried (due to following
action module missing or classifier-initiated retry), in which case
action init code tries to insert action to idr with index that was
assigned on previous iteration. During retry the index can be reused
by another action that was inserted concurrently, which causes
unintended action sharing between filters.
To fix described race condition, save action idr index to temporary
stack-allocated variable instead on nla data.
Fixes: 0190c1d452a9 ("net: sched: atomically check-allocate action")

[ Upstream commit c3953a3c2d3175d2f9f0304c9a1ba89e7743c5e4 ]
Fix two reset-gpio sanity checks which were never converted to use
gpio_is_valid(), and make sure to use -EINVAL to indicate a missing
reset line also for the UART-driver module parameter and for the USB
driver.
This specifically prevents the UART and USB drivers from incidentally
trying to request and use gpio 0, and also avoids triggering a WARN() in
gpio_to_desc() during probe when no valid reset line has been specified.

Subject: [PATCH 801/826] tipc: compat: allow tipc commands without arguments
[ Upstream commit 4da5f0018eef4c0de31675b670c80e82e13e99d1 ]
Commit 2753ca5d9009 ("tipc: fix uninit-value in tipc_nl_compat_doit")
broke older tipc tools that use compat interface (e.g. tipc-config from
tipcutils package):
% tipc-config -p
operation not supported
The commit started to reject TIPC netlink compat messages that do not
have attributes. It is too restrictive because some of such messages are
valid (they don't need any arguments):
% grep 'tx none' include/uapi/linux/tipc_config.h
#define TIPC_CMD_NOOP 0x0000 /* tx none, rx none */
#define TIPC_CMD_GET_MEDIA_NAMES 0x0002 /* tx none, rx media_name(s) */
#define TIPC_CMD_GET_BEARER_NAMES 0x0003 /* tx none, rx bearer_name(s) */
#define TIPC_CMD_SHOW_PORTS 0x0006 /* tx none, rx ultra_string */
#define TIPC_CMD_GET_REMOTE_MNG 0x4003 /* tx none, rx unsigned */
#define TIPC_CMD_GET_MAX_PORTS 0x4004 /* tx none, rx unsigned */
#define TIPC_CMD_GET_NETID 0x400B /* tx none, rx unsigned */
#define TIPC_CMD_NOT_NET_ADMIN 0xC001 /* tx none, rx none */
This patch relaxes the original fix and rejects messages without
arguments only if such arguments are expected by a command (reg_type is
non zero).

[ Upstream commit 4b663366246be1d1d4b1b8b01245b2e88ad9e706 ]
- v1 -> v2: Move skb_set_owner_w to __tun_build_skb to reduce patch size
Small packets going out of a tap device go through an optimized code
path that uses build_skb() rather than sock_alloc_send_pskb(). The
latter calls skb_set_owner_w(), but the small packet code path does not.
The net effect is that small packets are not owned by the userland
application's socket (e.g. QEMU), while large packets are.
This can be seen with a TCP session, where packets are not owned when
the window size is small enough (around PAGE_SIZE), while they are once
the window grows (note that this requires the host to support virtio
tso for the guest to offload segmentation).
All this leads to inconsistent behaviour in the kernel, especially on
netfilter modules that uses sk->socket (e.g. xt_owner).

Subject: [PATCH 804/826] net/mlx5e: Prevent encap flow counter update async to
user query
[ Upstream commit 90bb769291161cf25a818d69cf608c181654473e ]
This patch prevents a race between user invoked cached counters
query and a neighbor last usage updater.
The cached flow counter stats can be queried by calling
"mlx5_fc_query_cached" which provides the number of bytes and
packets that passed via this flow since the last time this counter
was queried.
It does so by reducting the last saved stats from the current, cached
stats and then updating the last saved stats with the cached stats.
It also provide the lastuse value for that flow.
Since "mlx5e_tc_update_neigh_used_value" needs to retrieve the
last usage time of encapsulation flows, it calls the flow counter
query method periodically and async to user queries of the flow counter
using cls_flower.
This call is causing the driver to update the last reported bytes and
packets from the cache and therefore, future user queries of the flow
stats will return lower than expected number for bytes and packets
since the last saved stats in the driver was updated async to the last
saved stats in cls_flower.
This causes wrong stats presentation of encapsulation flows to user.
Since the neighbor usage updater only needs the lastuse stats from the
cached counter, the fix is to use a dedicated lastuse query call that
returns the lastuse value without synching between the cached stats and
the last saved stats.

Subject: [PATCH 805/826] r8169: don't use MSI before RTL8168d
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
[ Upstream commit 003bd5b4a7b4a94b501e3a1e2e7c9df6b2a94ed4 ]
It was reported that after resuming from suspend network fails with
error "do_IRQ: 3.38 No irq handler for vector", see [0]. Enabling WoL
can work around the issue, but the only actual fix is to disable MSI.
So let's mimic the behavior of the vendor driver and disable MSI on
all chip versions before RTL8168d.

Subject: [PATCH 806/826] compat_ioctl: pppoe: fix PPPOEIOCSFWD handling
[ Upstream commit 055d88242a6046a1ceac3167290f054c72571cd9 ]
Support for handling the PPPOEIOCSFWD ioctl in compat mode was added in
linux-2.5.69 along with hundreds of other commands, but was always broken
sincen only the structure is compatible, but the command number is not,
due to the size being sizeof(size_t), or at first sizeof(sizeof((struct
sockaddr_pppox)), which is different on 64-bit architectures.
Guillaume Nault adds:
And the implementation was broken until 2016 (see 29e73269aa4d ("pppoe:
fix reference counting in PPPoE proxy")), and nobody ever noticed. I
should probably have removed this ioctl entirely instead of fixing it.
Clearly, it has never been used.
Fix it by adding a compat_ioctl handler for all pppoe variants that
translates the command number and then calls the regular ioctl function.
All other ioctl commands handled by pppoe are compatible between 32-bit
and 64-bit, and require compat_ptr() conversion.
This should apply to all stable kernels.

commit 6b115bf58e6f013ca75e7115aabcbd56c20ff31d upstream.
cgroup_release() calls cgroup_subsys->release() which is used by the
pids controller to uncharge its pid. We want to use it to manage
iteration of dying tasks which requires putting it before
__unhash_process(). Move cgroup_release() above __exit_signal().
While this makes it uncharge before the pid is freed, pid is RCU freed
anyway and the window is very narrow.

Subject: [PATCH 808/826] cgroup: Implement css_task_iter_skip()
commit b636fd38dc40113f853337a7d2a6885ad23b8811 upstream.
When a task is moved out of a cset, task iterators pointing to the
task are advanced using the normal css_task_iter_advance() call. This
is fine but we'll be tracking dying tasks on csets and thus moving
tasks from cset->tasks to (to be added) cset->dying_tasks. When we
remove a task from cset->tasks, if we advance the iterators, they may
move over to the next cset before we had the chance to add the task
back on the dying list, which can allow the task to escape iteration.
This patch separates out skipping from advancing. Skipping only moves
the affected iterators to the next pointer rather than fully advancing
it and the following advancing will recognize that the cursor has
already been moved forward and do the rest of advancing. This ensures
that when a task moves from one list to another in its cset, as long
as it moves in the right direction, it's always visible to iteration.
This doesn't cause any visible behavior changes.

Subject: [PATCH 809/826] cgroup: Include dying leaders with live threads in
PROCS iterations
commit c03cd7738a83b13739f00546166969342c8ff014 upstream.
CSS_TASK_ITER_PROCS currently iterates live group leaders; however,
this means that a process with dying leader and live threads will be
skipped. IOW, cgroup.procs might be empty while cgroup.threads isn't,
which is confusing to say the least.
Fix it by making cset track dying tasks and include dying leaders with
live threads in PROCS iteration.

Subject: [PATCH 810/826] cgroup: css_task_iter_skip()'d iterators must be
advanced before accessed
commit cee0c33c546a93957a52ae9ab6bebadbee765ec5 upstream.
b636fd38dc40 ("cgroup: Implement css_task_iter_skip()") introduced
css_task_iter_skip() which is used to fix task iterations skipping
dying threadgroup leaders with live threads. Skipping is implemented
as a subportion of full advancing but css_task_iter_next() forgot to
fully advance a skipped iterator before determining the next task to
visit causing it to return invalid task pointers.
Fix it by making css_task_iter_next() fully advance the iterator if it
has been skipped since the previous iteration.

Subject: [PATCH 811/826] cgroup: Fix css_task_iter_advance_css_set() cset skip
condition
commit c596687a008b579c503afb7a64fcacc7270fae9e upstream.
While adding handling for dying task group leaders c03cd7738a83
("cgroup: Include dying leaders with live threads in PROCS
iterations") added an inverted cset skip condition to
css_task_iter_advance_css_set(). It should skip cset if it's
completely empty but was incorrectly testing for the inverse condition
for the dying_tasks list. Fix it.

Subject: [PATCH 812/826] spi: bcm2835: Fix 3-wire mode if DMA is enabled
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
commit 8d8bef50365847134b51c1ec46786bc2873e4e47 upstream.
Commit 6935224da248 ("spi: bcm2835: enable support of 3-wire mode")
added 3-wire support to the BCM2835 SPI driver by setting the REN bit
(Read Enable) in the CS register when receiving data. The REN bit puts
the transmitter in high-impedance state. The driver recognizes that
data is to be received by checking whether the rx_buf of a transfer is
non-NULL.
Commit 3ecd37edaa2a ("spi: bcm2835: enable dma modes for transfers
meeting certain conditions") subsequently broke 3-wire support because
it set the SPI_MASTER_MUST_RX flag which causes spi_map_msg() to replace
rx_buf with a dummy buffer if it is NULL. As a result, rx_buf is
*always* non-NULL if DMA is enabled.
Reinstate 3-wire support by not only checking whether rx_buf is non-NULL,
but also checking that it is not the dummy buffer.
