Pull mmiowb removal from Will Deacon:
"Remove Mysterious Macro Intended to Obscure Weird Behaviours (mmiowb())
Remove mmiowb() from the kernel memory barrier API and instead, for
architectures that need it, hide the barrier inside spin_unlock() when
MMIO has been performed inside the critical section.
The only relatively recent changes have been addressing review
comments on the documentation, which is in a much better shape thanks
to the efforts of Ben and Ingo.
I was initially planning to split this into two pull requests so that
you could run the coccinelle script yourself, however it's been plain
sailing in linux-next so I've just included the whole lot here to keep
things simple"

====================
wireless-drivers fixes for 5.1
Third set of fixes for 5.1.
iwlwifi
* fix an oops when creating debugfs entries
* fix bug when trying to capture debugging info while in rfkill
* prevent potential uninitialized memory dumps into debugging logs
* fix some initialization parameters for AX210 devices
* fix an oops with non-MSIX devices
* fix an oops when we receive a packet with bogus lengths
* fix a bug that prevented 5350 devices from working
* fix a small merge damage from the previous series
mwifiex
* fig regression with resume on SDIO
ath10k
* fix locking problem with crashdump
* fix warnings during suspend and resume
Also note that this pull conflicts with net-next. And I want to emphasie
that it's really net-next, so when you pull this to net tree it should
go without conflicts. Stephen reported the conflict here:
https://lkml.kernel.org/r/20190429115338.5decb50b@canb.auug.org.au
In iwlwifi oddly commit 154d4899e411 adds the IS_ERR_OR_NULL() in
wireless-drivers but commit c9af7528c331 removes the whole check in
wireless-drivers-next. The fix is easy, just drop the whole check for
mvmvif->dbgfs_dir in iwlwifi/mvm/debugfs-vif.c, it's unneeded anyway.

ath10k_mac_vif_chan() always returns an error for the given vif
during system-wide resume which reliably triggers two WARN_ON()s
in ath10k_bss_info_changed() and they are not particularly
useful in that code path, so drop them.

ath10k_pci_fw_crashed_dump() is called from NAPI contexts, and firmware
memory dumps are retrieved using the diag memory interface.
A simple reproduction case is to run this on QCA6174A /
WLAN.RM.4.4.1-00132-QCARMSWP-1, which happens to be a way to b0rk the
firmware:
dd if=/sys/kernel/debug/ieee80211/phy0/ath10k/mem_value bs=4K count=1
of=/dev/null
(NB: simulated firmware crashes, via debugfs, don't trigger firmware
dumps.)
The fix is to move the crash-dump into a workqueue context, and avoid
relying on 'data_lock' for most mutual exclusion. We only keep using it
here for protecting 'fw_crash_counter', while the rest of the coredump
buffers are protected by a new 'dump_mutex'.
I've tested the above with simulated firmware crashes (debugfs 'reset'
file), real firmware crashes (the 'dd' command above), and a variety of
reboot and suspend/resume configurations on QCA6174A.

We don't check for the validity of the lengths in the packet received
from the firmware. If the MPDU length received in the rx descriptor
is too short to contain the header length and the crypt length
together, we may end up trying to copy a negative number of bytes
(headlen - hdrlen < 0) which will underflow and cause us to try to
copy a huge amount of data. This causes oopses such as this one:

In bnxt_rx_pkt(), if the driver encounters BD errors, it will recycle
the buffers and jump to the end where the uninitailized variable "len"

may not be valid when we get this type of error.

try the call again by setting the ALL_MCAST flag which is more

This way, slhc_free() accepts what slhc_init() returns, whether that is
an error or not.
In particular, the pattern in sl_alloc_bufs() is
slcomp = slhc_init(16, 16);
...
slhc_free(slcomp);
for the error handling path, and rather than complicate that code, just
make it ok to always free what was returned by the init function.
That's what the code used to do before commit 4ab42d78e37a ("ppp, slip:
Validate VJ compression slot parameters completely") when slhc_init()
just returned NULL for the error case, with no actual indication of the
details of the error.

marvell_get_sset_count() returns how many statistics counters there

marvell_get_strings() does not make this distinction, and always

The commit fc3a2fcaa1ba ("mwifiex: use atomic bitops to represent
adapter status variables") had a fairly straightforward bug in it. It
contained this bit of diff:
- if (!adapter->is_suspended) {
+ if (test_bit(MWIFIEX_IS_SUSPENDED, &adapter->work_flags)) {
As you can see the patch missed the "!" when converting to the atomic
bitops. This meant that the resume hasn't done anything at all since
that commit landed and suspend/resume for mwifiex SDIO cards has been
totally broken.
After fixing this mwifiex suspend/resume appears to work again, at
least with the simple testing I've done.

The flags field in 'struct shash_desc' never actually does anything.
The only ostensibly supported flag is CRYPTO_TFM_REQ_MAY_SLEEP.
However, no shash algorithm ever sleeps, making this flag a no-op.
With this being the case, inevitably some users who can't sleep wrongly
pass MAY_SLEEP. These would all need to be fixed if any shash algorithm
actually started sleeping. For example, the shash_ahash_*() functions,
which wrap a shash algorithm with the ahash API, pass through MAY_SLEEP
from the ahash API to the shash API. However, the shash functions are
called under kmap_atomic(), so actually they're assumed to never sleep.
Even if it turns out that some users do need preemption points while
hashing large buffers, we could easily provide a helper function
crypto_shash_update_large() which divides the data into smaller chunks
and calls crypto_shash_update() and cond_resched() for each chunk. It's
not necessary to have a flag in 'struct shash_desc', nor is it necessary
to make individual shash algorithms aware of this at all.
Therefore, remove shash_desc::flags, and document that the
crypto_shash_*() functions can be called from any context.

If we add a bond device which is already the master of the team interface,
we will hold the team->lock in team_add_slave() first and then request the
lock in team_set_mac_address() again. The functions are called like:
- team_add_slave()
- team_port_add()
- team_port_enter()
- team_modeop_port_enter()
- __set_port_dev_addr()
- dev_set_mac_address()
- bond_set_mac_address()
- dev_set_mac_address()
- team_set_mac_address
Although team_upper_dev_link() would check the upper devices but it is
called too late. Fix it by adding a checking before processing the slave.

Since there are more IOT2040 variants with identical hardware but
different asset tags, the asset tag matching should be adjusted to
support them.
For the board name "SIMATIC IOT2000", currently there are 2 types of
hardware, IOT2020 and IOT2040. The IOT2020 is identified by its unique
asset tag. Match on it first. If we then match on the board name only,
we will catch all IOT2040 variants. In the future there will be no other
devices with the "SIMATIC IOT2000" DMI board name but different
hardware.

During driver initialization the driver sends a reset to the device and
waits for the firmware to signal that it is ready to continue.
Commit d2f372ba0914 ("mlxsw: pci: Increase PCI SW reset timeout")
increased the timeout to 13 seconds due to longer PHY calibration in
Spectrum-2 compared to Spectrum-1.
Recently it became apparent that this timeout is too short and therefore
this patch increases it again to a safer limit that will be reduced in
the future.

Both Spectrum-1 and Spectrum-2 chips are currently configured such that
pairs of TC n (which is used for UC traffic) and TC n+8 (which is used
for MC traffic) are feeding into the same subgroup. Strict
prioritization is configured between the two TCs, and by enabling
MC-aware mode on the switch, the lower-numbered (UC) TCs are favored
over the higher-numbered (MC) TCs.
On Spectrum-2 however, there is an issue in configuration of the
MC-aware mode. As a result, MC traffic is prioritized over UC traffic.
To work around the issue, configure the MC TCs with DWRR mode (while
keeping the UC TCs in strict mode).
With this patch, the multicast-unicast arbitration results in the same
behavior on both Spectrum-1 and Spectrum-2 chips.

debugfs can now report an error code if something went wrong instead of
just NULL. So if the return value is to be used as a "real" dentry, it
needs to be checked if it is an error before dereferencing it.
This is now happening because of ff9fb72bc077 ("debugfs: return error
values, not NULL"). If multiple iwlwifi devices are in the system, this
can cause problems when the driver attempts to create the main debugfs
directory again. Later on in the code we fail horribly by trying to
dereference a pointer that is an error value.

In ini debug TLVs bit 24 is set. The driver relies on it in the memory
allocation for the debug configuration. This implementation is
problematic in case of a new debug TLV that is not supported yet is added
and uses bit 24. In such a scenario the driver allocate space without
using it which causes errors in the apply point enabling flow.
Solve it by explicitly checking if a given TLV is part of the list of
the supported ini debug TLVs.

If we fail to initialize because rfkill is enabled, then trying
