V3:
- Drop the SoC regulator constraints for
  regulator-min-microamp
  regulator-max-microamp
  These will be applied on a per-board basis - Mark Brown

V2:
The first version of this patch set the current limit to 3 amps as was done
in downstream. Mark indicated a preference to set this on a per-system
basis instead of blitzing it, as in downstream.

Looking at what was upstream versus what was in my working tree I saw that
in fact the VBUS boost driver had been upstreamed minus accompanying DTS in
pm8150b.

So there's no need for a fixes as this driver doesn't appear to be in use.
A subsequent patchset will enable the VBUS boost for the two relevant
upstream platforms.

First thing though, is the driver + dts change.

- Use regulator_set_current_limit_regmap/regulator_get_current_limit_regmap
  with a relevant current-to-bitmap lookup.

- Add a parallel DTS entry to the pm8150b
  It looks like this was submitted upstream but not followed up on

  I've add regulator-min-microamp/regulator-max-microamp to Wesley's
  original work.

I've made sure to test that its possible to set the current to anything in
the range of 500 mA to 3 A and confirmed the output on a scope.

Once these two patches are in, I'll send out board enablement for the

linux/kconfig.h: replace IF_ENABLED() with PTR_IF() in <linux/kernel.h>

<linux/kconfig.h> is included from all the kernel-space source files,
including C, assembly, linker scripts. It is intended to contain a
minimal set of macros to evaluate CONFIG options.

IF_ENABLED() is an intruder here because (x ? y : z) is C code, which
should not be included from assembly files or linker scripts.

Also, <linux/kconfig.h> is no longer self-contained because NULL is
defined in <linux/stddef.h>.

Move IF_ENABLED() out to <linux/kernel.h> as PTR_IF(). PTF_IF()
takes the general boolean expression instead of a CONFIG option
so that it fits better in <linux/kernel.h>.

3 years agonet: stmmac: Do not enable RX FIFO overflow interrupts
Yannick Vignon [Thu, 6 May 2021 14:33:12 +0000 (16:33 +0200)]
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.

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.

Magnus Karlsson [Mon, 26 Apr 2021 11:14:01 +0000 (13:14 +0200)]
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.

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.
