2021-05-08smb3: if max_channels set to more than one channel request multichannelSteve French1-0/+3

<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>.

2021-05-07net: stmmac: Do not enable RX FIFO overflow interruptsYannick Vignon2-18/+3
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.

2021-05-07mptcp: fix splat when closing unaccepted socketPaolo Abeni1-2/+1
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.

2021-05-07i40e: fix broken XDP supportMagnus Karlsson1-6/+2
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.

2021-05-07treewide: remove editor modelines and cruftMasahiro Yamada157-627/+110
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.
