The skb_recv_datagram() in ax25_recvmsg() will hold lock_sock

doesn`t connect to server and calls read() directly, it will not

This patch replaces skb_recv_datagram() with an open-coded variant of it
releasing the socket lock before the __skb_wait_for_more_packets() call
and re-acquiring it after such call in order that other functions that
need socket lock could be executed.
what's more, the socket lock will be released only when recvmsg() will
block and that should produce nicer overall behavior.

The extra byte inserted by usbnet.c when
(length % dev->maxpacket == 0) is causing problems to device.
This patch sets FLAG_SEND_ZLP to avoid this.
Tested with: 0b95:1790 ASIX Electronics Corp. AX88179 Gigabit Ethernet
Problems observed:
======================================================================
1) Using ssh/sshfs. The remote sshd daemon can abort with the message:
"message authentication code incorrect"
This happens because the tcp message sent is corrupted during the
USB "Bulk out". The device calculate the tcp checksum and send a
valid tcp message to the remote sshd. Then the encryption detects
the error and aborts.
2) NETDEV WATCHDOG: ... (ax88179_178a): transmit queue 0 timed out
3) Stop normal work without any log message.
The "Bulk in" continue receiving packets normally.
The host sends "Bulk out" and the device responds with -ECONNRESET.
(The netusb.c code tx_complete ignore -ECONNRESET)
Under normal conditions these errors take days to happen and in
intense usage take hours.
A test with ping gives packet loss, showing that something is wrong:
ping -4 -s 462 {destination} # 462 = 512 - 42 - 8
Not all packets fail.
My guess is that the device tries to find another packet starting
at the extra byte and will fail or not depending on the next
bytes (old buffer content).

Disable VF's RX/TX queues, when VIRTCHNL_OP_CONFIG_VSI_QUEUES fail.
Not disabling them might lead to scenario, where PF driver leaves VF
queues enabled, when VF's VSI failed queue config.
In this scenario VF should not have RX/TX queues enabled. If PF failed
to set up VF's queues, VF will reset due to TX timeouts in VF driver.

The offset was being incorrectly calculated for E822 - that led to
collisions in choosing TX timestamp register location when more than
one port was trying to use timestamping mechanism.
In E822 one quad is being logically split between ports, so quad 0 is
having trackers for ports 0-3, quad 1 ports 4-7 etc. Each port should
have separate memory location for tracking timestamps. Due to error for
example ports 1 and 2 had been assigned to quad 0 with same offset (0),
while port 1 should have offset 0 and 1 offset 16.
Fix it by correctly calculating quad offset.

Both RIF and ACL flow counters use a 24-bit SW-managed counter address to
communicate which counter they want to bind.
In a number of Spectrum FW releases, binding a RIF counter is broken and
slices the counter index to 16 bits. As a result, on Spectrum-2 and above,
no more than about 410 RIF counters can be effectively used. This
translates to 205 netdevices for which L3 HW stats can be enabled. (This
does not happen on Spectrum-1, because there are fewer counters available
overall and the counter index never exceeds 16 bits.)
Binding counters to ACLs does not have this issue. Therefore reorder the
counter allocation scheme so that RIF counters come first and therefore get
lower indices that are below the 16-bit barrier.

net: axienet: fix DMA Tx error
We ran into multiple DMA TX errors while writing files over a network
block device running on top of a DMA-connected AXI Ethernet device on
64-bit RISC-V machines. The errors indicated that the DMA had fetched a
null descriptor and we found that the reason for this is that AXI DMA had
unexpectedly processed a partially updated tail descriptor pointer. To
fix it, we suggest that the driver should use one 64-bit write instead
of two 32-bit writes to perform such update if possible. For those
archectures where double-word load/stores are unavailable, e.g. 32-bit
archectures, force a driver probe failure if the driver finds 64-bit
capability on DMA.
====================

According to commit f735c40ed9 ("net: axienet: Autodetect 64-bit DMA
capability") and AXI-DMA spec (pg021), on 64-bit capable dma, only
writing MSB part of tail descriptor pointer causes DMA engine to start
fetching descriptors. However, we found that it is true only if dma is in
idle state. In other words, dma would use a tailp even if it only has LSB
updated, when the dma is running.
The non-atomicity of this behavior could be problematic if enough
delay were introduced in between the 2 writes. For example, if an
interrupt comes right after the LSB write and the cpu spends long
enough time in the handler for the dma to get back into idle state by
completing descriptors, then the seconcd write to MSB would treat dma
to start fetching descriptors again. Since the descriptor next to the
one pointed by current tail pointer is not filled by the kernel yet,
fetching a null descriptor here causes a dma internal error and halt
the dma engine down.
We suggest that the dma engine should start process a 64-bit MMIO write
to the descriptor pointer only if ONE 32-bit part of it is written on all
states. Or we should restrict the use of 64-bit addressable dma on 32-bit
platforms, since those devices have no instruction to guarantee the write
to LSB and MSB part of tail pointer occurs atomically to the dma.
initial condition:
curp = x-3;
tailp = x-2;
LSB = x;
MSB = 0;
cpu: |dma:
iowrite32(LSB, tailp) | completes #(x-3) desc, curp = x-3
... | tailp updated
=> irq | completes #(x-2) desc, curp = x-2
... | completes #(x-1) desc, curp = x-1

Currently it is not safe to config the IP as 64-bit addressable on 32-bit
archectures, which cannot perform a double-word store on its descriptor
pointers. The pointer is 64-bit wide if the IP is configured as 64-bit,
and the device would process the partially updated pointer on some
states if the pointer was updated via two store-words. To prevent such
condition, we force a probe fail if we discover that the IP has 64-bit
capability but it is not running on a 64-Bit kernel.
This is a series of patch (1/2). The next patch must be applied in order

Merge fixes for regressions introduced by the recent rework of the
system reboot/poweroff code.
* pm-sysoff:
kernel/reboot: Fix powering off using a non-syscall code paths
kernel/reboot: Use static handler for register_platform_power_off()
There's no reason to list the same value twice in an 'enum'. This was fixed
treewide in commit c3b0068194 ("dt-bindings: Fix 'enum' lists with
duplicate entries"), but this one got added in the merge window.
A meta-schema change will catch future cases.

The EFI save/restore code is confused. When saving the check for saving
FFR is inverted due to confusion with the streaming mode check, and when
restoring we check if we need to restore FFR by checking the percpu
efi_sm_state without the required wrapper rather than based on the
combination of FA64 support and streaming mode.
