Before commit 1e58252e33 ("mwifiex: Fix heap overflow in
mmwifiex_process_tdls_action_frame()"),
mwifiex_process_tdls_action_frame() already had too many magic numbers.
But this commit just added a ton more, in the name of checking for
buffer overflows. That seems like a really bad idea.
Let's make these magic numbers a little less magic, by
(a) factoring out 'pos[1]' as 'ie_len'
(b) using 'sizeof' on the appropriate source or destination fields where
possible, instead of bare numbers
(c) dropping redundant checks, per below.
Regarding redundant checks: the beginning of the loop has this:
if (pos + 2 + pos[1] > end)
break;
but then individual 'case's include stuff like this:
if (pos > end - 3)
return;
if (pos[1] != 1)
return;
Note that the second 'return' (validating the length, pos[1]) combined
with the above condition (ensuring 'pos + 2 + length' doesn't exceed
'end'), makes the first 'return' (whose 'if' can be reworded as 'pos >
end - pos[1] - 2') redundant. Rather than unwind the magic numbers
there, just drop those conditions.

There are two error paths where "ret" wasn't set. Also one error path
we set the error code to -EINVAL but we should just preserve the error
code from ath11k_hal_srng_get_entrysize(). That function only returns
-EINVAL so this doesn't change anything.
I removed the "ret = 0;" initializers so that hopefully GCC will be able
to detect these sorts of bugs in the future.

100GbE Intel Wired LAN Driver Updates 2020-01-25
This series contains updates to the ice driver to add support for RSS.
Henry and Tony enable the driver to write the filtering hardware tables
to allow for changing of RSS rules, also introduced and initialized the
structures for storing the configuration. Then followed it up by
creating an extraction sequence based on the packet header protocols to
be programmed. Next was storing the TCAM entry with the profile data
and VSI group in the respective software structures.
Md Fahad sets up the configuration to support RSS tables for the virtual
function (VF) driver (iavf). Add support for flow types TCP4, TCP6,
UDP4, UDP6, SCTP4 and SCTP6 for RSS via ethtool.

This reverts commit 76d164f582.
PCIe hung issue was observed on multiple platforms. The issue was reproduced
when DUT was configured as AP and associated with 50+ STAs.
For QCA9984/QCA9888, the DMA_BURST_SIZE register controls the AXI burst size
of the RD/WR access to the HOST MEM.
0 - No split , RAW read/write transfer size from MAC is put out on bus
as burst length
1 - Split at 256 byte boundary
2,3 - Reserved
With PCIe protocol analyzer, we can see DMA Read crossing 4KB boundary when
issue happened. It broke PCIe spec and caused PCIe stuck. So revert
the default value from 0 to 1.
Tested: IPQ8064 + QCA9984 with firmware 10.4-3.10-00047

2. run simulate fail:

The simulate fail of sdio is not a real sdio transter fail, it only
set an error status in mmc_should_fail_request after the transfer end,
actually the transfer is success, then sdio_io_rw_ext_helper will
return error status and stop transfer the left data. For example,
the really RX len is 286 bytes, then it will split to 2 blocks in
sdio_io_rw_ext_helper, one is 256 bytes, left is 30 bytes, if the
first 256 bytes get an error status by mmc_should_fail_request,then
the left 30 bytes will not read in this RX operation. Then when the
next RX arrive, the left 30 bytes will be considered as the header
of the read, the top 8 bytes will be considered as ath10k_htc_hdr,
but actually the 8 bytes is not the ath10k_htc_hdr, so the act_len
from this ath10k_htc_hdr is not correct, if it is a big value, such
as 57013, it will trigger skb_panic.
Drop the skb with invalid length will be reasonable.
This patch only effect sdio chips.

Syzbot managed to trigger a use after free "KASAN: use-after-free Write

cause I have found is that we are not holding lock_sock(sk) when we do
the hci_dev_put(hdev) in hci_sock_release(). My theory is that the bind
and the release are racing against each other which results in this use
after free.

- Small Kconfig fix for OPTEE (adds a depend on MMU) to avoid build

In fs_open(), 'vcc' is allocated through kmalloc() and assigned to
'atm_vcc->dev_data.' In the following execution, if an error occurs, e.g.,
there is no more free channel, an error code EBUSY or ENOMEM will be
returned. However, 'vcc' is not deallocated, leading to memory leaks. Note
that, in normal cases where fs_open() returns 0, 'vcc' will be deallocated
in fs_close(). But, if fs_open() fails, there is no guarantee that
fs_close() will be invoked.
To fix this issue, deallocate 'vcc' before the error code is returned.

Merge conflict: once merge with net-next, a contextual conflict will

To resolve, just delete ALL of the conflicting hunk from net.
So sorry for the small mess ..

caused by the previous patch ("btrfs: scrub: Require mandatory block
group RO for dev-replace"). Hitting ENOSPC is possible and could happen
when the block group is set read-only, preventing NOCOW writes to the
area that's being accessed by dev-replace.
This has happend with scratch devices of size 12G but not with 5G and
20G, so this is depends on timing and other activity on the filesystem.
The whole replace operation is restartable, the space state should be
examined by the user in any case.
The error code is propagated back to the ioctl caller so the kernel
warning is causing false alerts.

mlxsw: Offload TBF
Petr says:
In order to allow configuration of shapers on Spectrum family of
machines, recognize TBF either as root Qdisc, or as a child of ETS or
PRIO. Configure rate of maximum shaper according to TBF rate setting,
and maximum shaper burst size according to TBF burst setting.
- Patches #1 and #2 make the TBF shaper suitable for offloading.
- Patches #3, #4 and #5 are refactoring aimed at easier support of leaf
Qdiscs in general.
- Patches #6 to #10 gradually introduce TBF offload.
- Patches #11 to #14 add selftests.

Add a test that runs traffic across a port throttled with TBF. The test
checks that the observed throughput is within +-5% from the installed
shaper.
To allow checking both the software datapath and the offloaded one, make
the test suitable for inclusion from driver-specific wrapper. Introduce
such wrappers for mlxsw.

The function busywait() is handy as a safety-latched variant of a while
loop. Many selftests deal specifically with counter values, and busywaiting
on them is likely to be rather common (it is not quite common now, but
busywait() has not been around for very long). To facilitate expressing
simply what is tested, introduce two helpers:
- until_counter_is(), which can be used as a predicate passed to
busywait(), which holds when expression, which is itself passed as an
argument to until_counter_is(), reaches a desired value.
- busywait_for_counter(), which is useful for waiting until a given counter
changes "by" (as opposed to "to") a certain amount.

The function humanize() is used for converting value in bits/s to a
human-friendly approximate value in Kbps, Mbps or Gbps. There is nothing
hardware-specific in that, so move the function to lib.sh.
