Amelie Delaunay 63e006c107 pinctrl: stmfx: fix valid_mask init sequence
With stmfx_pinctrl_gpio_init_valid_mask callback, gpio_valid_mask was used
to initialize gpiochip valid_mask for gpiolib. But gpio_valid_mask was not
yet initialized. gpio_valid_mask required gpio-ranges to be registered,
this is the case after gpiochip_add_data call. But init_valid_mask
callback is also called under gpiochip_add_data. gpio_valid_mask
initialization cannot be moved before gpiochip_add_data because
gpio-ranges are not registered.
So, it is not possible to use init_valid_mask callback.
To avoid this issue, get rid of valid_mask and rely on ranges.

Pavel Shilovsky d243af7ab9 SMB3: Fix persistent handles reconnect
When the client hits a network reconnect, it re-opens every open
file with a create context to reconnect a persistent handle. All
create context types should be 8-bytes aligned but the padding
was missed for that one. As a result, some servers don't allow
us to reconnect handles and return an error. The problem occurs
when the problematic context is not at the end of the create
request packet. Fix this by adding a proper padding at the end
of the reconnect persistent handle context.

changzhu 589b64a7e3 drm/amdgpu: add dummy read by engines for some GCVM status registers in gfx10
The GRBM register interface is now capable of bursting 1 cycle per
register wr->wr, wr->rd much faster than previous muticycle per
transaction done interface.  This has caused a problem where
status registers requiring HW to update have a 1 cycle delay, due
to the register update having to go through GRBM.

For cp ucode, it has realized dummy read in cp firmware.It covers
the use of WAIT_REG_MEM operation 1 case only.So it needs to call
gfx_v10_0_wait_reg_mem in gfx10. Besides it also needs to add warning to
update firmware in case firmware is too old to have function to realize
dummy read in cp firmware.

For sdma ucode, it hasn't realized dummy read in sdma firmware. sdma is
moved to gfxhub in gfx10. So it needs to add dummy read in driver
between amdgpu_ring_emit_wreg and amdgpu_ring_emit_reg_wait for sdma_v5_0.

====================
net/tls: add a TX lock

Some time ago Pooja and Mallesham started reporting crashes with
an async accelerator. After trying to poke the existing logic into
shape I came to the conclusion that it can't be trusted, and to
preserve our sanity we should just add a lock around the TX side.

First patch removes the sk_write_pending checks from the write
space callbacks. Those don't seem to have a logical justification.

Patch 2 adds the TX lock and patch 3 associated test (which should
hang with current net).

Mallesham reports that even with these fixes applied the async
accelerator workload still occasionally hangs waiting for socket
memory. I suspect that's strictly related to the way async crypto
is integrated in TLS, so I think we should get these into net or
net-next and move from there.

Jakub Kicinski 79ffe6087e net/tls: add a TX lock
TLS TX needs to release and re-acquire the socket lock if send buffer
fills up.

TLS SW TX path currently depends on only allowing one thread to enter
the function by the abuse of sk_write_pending. If another writer is
already waiting for memory no new ones are allowed in.

This has two problems:
 - writers don't wake other threads up when they leave the kernel;
   meaning that this scheme works for single extra thread (second
   application thread or delayed work) because memory becoming
   available will send a wake up request, but as Mallesham and
   Pooja report with larger number of threads it leads to threads
   being put to sleep indefinitely;
 - the delayed work does not get _scheduled_ but it may _run_ when
   other writers are present leading to crashes as writers don't
   expect state to change under their feet (same records get pushed
   and freed multiple times); it's hard to reliably bail from the
   work, however, because the mere presence of a writer does not
   guarantee that the writer will push pending records before exiting.

Ensuring wakeups always happen will make the code basically open
code a mutex. Just use a mutex.

The TLS HW TX path does not have any locking (not even the
sk_write_pending hack), yet it uses a per-socket sg_tx_data
array to push records.

record will be pushed. If the thread waiting for memory times out
the pending record may get stuck.

In case of tls_device there is no path where parial record is
set and writer present in the first place. Partial record is
set only in tls_push_sg() and tls_push_sg() will return an
error immediately. All tls_device callers of tls_push_sg()
will return (and not wait for memory) if it failed.

blkcg_print_stat() iterates blkgs under RCU and doesn't test whether
the blkg is online.  This can call into pd_stat_fn() on a pd which is
still being initialized leading to an oops.

The heaviest operation - recursively summing up rwstat counters - is
already done while holding the queue_lock.  Expand queue_lock to cover
the other operations and skip the blkg if it isn't online yet.  The
online state is protected by both blkcg and queue locks, so this
guarantees that only online blkgs are processed.

Dmytro Linkin 950d3af70e net/mlx5e: Use correct enum to determine uplink port
For vlan push action, if eswitch flow source capability is enabled, flow
source value compared with MLX5_VPORT_UPLINK enum, to determine uplink
port. This lead to syndrome in dmesg if try to add vlan push action.
For example:
 $ tc filter add dev vxlan0 ingress protocol ip prio 1 flower \
       enc_dst_port 4789 \
       action tunnel_key unset pipe \
       action vlan push id 20 pipe \
       action mirred egress redirect dev ens1f0_0
 $ dmesg
 ...
 [ 2456.883693] mlx5_core 0000:82:00.0: mlx5_cmd_check:756:(pid 5273): SET_FLOW_TABLE_ENTRY(0x936) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0xa9c090)
Use the correct enum value MLX5_FLOW_CONTEXT_FLOW_SOURCE_UPLINK.

The reference to object fence is dropped at the end of the loop.
However, it is dropped again outside the loop. The reference can be
dropped immediately after calling dma_fence_wait() in the loop and
thus the dropping operation outside the loop can be removed.

The object fence is not set to NULL after its reference is dropped. As a
result, its reference may be dropped again if error occurs after that,
which may lead to a use after free bug. To avoid the issue, fence is
explicitly set to NULL after dropping its reference.

changzhu a6522a5c63 drm/amdgpu: add dummy read by engines for some GCVM status registers in gfx10
The GRBM register interface is now capable of bursting 1 cycle per
register wr->wr, wr->rd much faster than previous muticycle per
transaction done interface.  This has caused a problem where
status registers requiring HW to update have a 1 cycle delay, due
to the register update having to go through GRBM.

For cp ucode, it has realized dummy read in cp firmware.It covers
the use of WAIT_REG_MEM operation 1 case only.So it needs to call
gfx_v10_0_wait_reg_mem in gfx10. Besides it also needs to add warning to
update firmware in case firmware is too old to have function to realize
dummy read in cp firmware.

For sdma ucode, it hasn't realized dummy read in sdma firmware. sdma is
moved to gfxhub in gfx10. So it needs to add dummy read in driver
between amdgpu_ring_emit_wreg and amdgpu_ring_emit_reg_wait for sdma_v5_0.
