mfd: axp20x: Allow AXP 806 chips without interrupt lines

Currently the AXP chip requires to have its IRQ line connected to some
interrupt controller, and will fail probing when this is not the case.

On a new Allwinner SoC (H616) there is no NMI pin anymore, and at
least one board does not connect the AXP's IRQ pin to anything else,
so the interrupt functionality of the AXP chip is simply not available.

Check whether the interrupt line number returned by the platform code is
valid, before trying to register the irqchip. If not, we skip this
registration, to avoid the driver to bail out completely.
Also we need to skip the power key functionality, as this relies on
a valid IRQ as well.

IF_ENABLED() is an intruder here because (x ? y : z) is C code, which

net: stmmac: Do not enable RX FIFO overflow interrupts

The RX FIFO overflows when the system is not able to process all received
packets and they start accumulating (first in the DMA queue in memory,
then in the FIFO). An interrupt is then raised for each overflowing packet
and handled in stmmac_interrupt(). This is counter-productive, since it
brings the system (or more likely, one CPU core) to its knees to process
the FIFO overflow interrupts.

stmmac_interrupt() handles overflow interrupts by writing the rx tail ptr
into the corresponding hardware register (according to the MAC spec, this
has the effect of restarting the MAC DMA). However, without freeing any rx
descriptors, the DMA stops right away, and another overflow interrupt is
raised as the FIFO overflows again. Since the DMA is already restarted at
the end of stmmac_rx_refill() after freeing descriptors, disabling FIFO
overflow interrupts and the corresponding handling code has no side effect,
and eliminates the interrupt storm when the RX FIFO overflows.

3 years agomptcp: fix splat when closing unaccepted socket
Paolo Abeni [Fri, 7 May 2021 00:16:38 +0000 (17:16 -0700)]
mptcp: fix splat when closing unaccepted socket

If userspace exits before calling accept() on a listener that had at least
one new connection ready, we get:

   Attempt to release TCP socket in state 8

This happens because the mptcp socket gets cloned when the TCP connection
is ready, but the socket is never exposed to userspace.

The client additionally sends a DATA_FIN, which brings connection into
CLOSE_WAIT state.  This in turn prevents the orphan+state reset fixup
in mptcp_sock_destruct() from doing its job.

Fixes: 3721b9b64676b ("mptcp: Track received DATA_FIN sequence number and add related helpers")

i40e: fix broken XDP support

Commit 12738ac4754e ("i40e: Fix sparse errors in i40e_txrx.c") broke
XDP support in the i40e driver. That commit was fixing a sparse error
in the code by introducing a new variable xdp_res instead of
overloading this into the skb pointer. The problem is that the code
later uses the skb pointer in if statements and these where not
extended to also test for the new xdp_res variable. Fix this by adding
the correct tests for xdp_res in these places.

The skb pointer was used to store the result of the XDP program by
overloading the results in the error pointer
ERR_PTR(-result). Therefore, the allocation failure test that used to
only test for !skb now need to be extended to also consider !xdp_res.

i40e_cleanup_headers() had a check that based on the skb value being
an error pointer, i.e. a result from the XDP program != XDP_PASS, and
if so start to process a new packet immediately, instead of populating
skb fields and sending the skb to the stack. This check is not needed
anymore, since we have added an explicit test for xdp_res being set
and if so just do continue to pick the next packet from the NIC.

netfilter: nftables: avoid potential overflows on 32bit arches

User space could ask for very large hash tables, we need to make sure
our size computations wont overflow.

nf_tables_newset() needs to double check the u64 size
will fit into size_t field.

3 years agotreewide: remove editor modelines and cruft
Masahiro Yamada [Fri, 7 May 2021 01:06:44 +0000 (18:06 -0700)]
treewide: remove editor modelines and cruft

The section "19) Editor modelines and other cruft" in
Documentation/process/coding-style.rst clearly says, "Do not include any
of these in source files."

I recently receive a patch to explicitly add a new one.

Let's do treewide cleanups, otherwise some people follow the existing code
and attempt to upstream their favoriate editor setups.

It is even nicer if scripts/checkpatch.pl can check it.

If we like to impose coding style in an editor-independent manner, I think
editorconfig (patch [1]) is a saner solution.
