40GbE Intel Wired LAN Driver Updates 2018-05-14
This series contains updates to virtchnl, i40e and i40evf.
Bruce cleans up whitespace and unnecessary parentheses in virtchnl.
Jake does a number of stat cleanups in the i40e driver, including
cleanup of code indentation, whitespace issues, remove duplicate stats,
fix grammar in code comment and general spring cleaning of the
statistics code.
Patryk fixes an issue where we recalculate vectors left and vectors
wanted but do not take into account the reduced number of queue pairs
per VSI.
Harshitha adds tx_busy stat to ethtool stats to track the number of
times we return NETDEV_TX_BUSY to the stack during transmit.
Paweł fixes a potential system crash when unloading the VF driver after
a hardware reset.

kernel: add support to collect hardware logs in crash recovery kernel
On production servers running variety of workloads over time, kernel
panic can happen sporadically after days or even months. It is
important to collect as much debug logs as possible to root cause
and fix the problem, that may not be easy to reproduce. Snapshot of
underlying hardware/firmware state (like register dump, firmware
logs, adapter memory, etc.), at the time of kernel panic will be very
helpful while debugging the culprit device driver.
This series of patches add new generic framework that enable device
drivers to collect device specific snapshot of the hardware/firmware
state of the underlying device in the crash recovery kernel. In crash
recovery kernel, the collected logs are added as elf notes to
/proc/vmcore, which is copied by user space scripts for post-analysis.
The sequence of actions done by device drivers to append their device
specific hardware/firmware logs to /proc/vmcore are as follows:
1. During probe (before hardware is initialized), device drivers
register to the vmcore module (via vmcore_add_device_dump()), with
callback function, along with buffer size and log name needed for
firmware/hardware log collection.
2. vmcore module allocates the buffer with requested size. It adds
an elf note and invokes the device driver's registered callback
function.
3. Device driver collects all hardware/firmware logs into the buffer
and returns control back to vmcore module.
The device specific hardware/firmware logs can be seen as elf notes
with note type 0x700, as shown below:
Displaying notes found at file offset 0x00001000 with length 0x040032c0:
Owner Data size Description
LINUX 0x02000fec Unknown note type: (0x00000700)

CORE 0x00000150 NT_PRSTATUS (prstatus structure)
VMCOREINFO 0x00000785 Unknown note type: (0x00000000)
Patch 1 adds API to vmcore module to allow drivers to register callback
to collect the device specific hardware/firmware logs. The logs will
be added to /proc/vmcore as elf notes.
Patch 2 updates read and mmap logic to append device specific hardware/
firmware logs as elf notes.
Patch 3 shows a cxgb4 driver example using the API to collect
hardware/firmware logs in crash recovery kernel, before hardware is
initialized.
Thanks,
Rahul

Update read and mmap logic to append device dumps as additional notes
before the other elf notes. We add device dumps before other elf notes
because the other elf notes may not fill the elf notes buffer
completely and we will end up with zero-filled data between the elf
notes and the device dumps. Tools will then try to decode this
zero-filled data as valid notes and we don't want that. Hence, adding
device dumps before the other elf notes ensure that zero-filled data
can be avoided. This also ensures that the device dumps and the
other elf notes can be properly mmaped at page aligned address.
Incorporate device dump size into the total vmcore size. Also update
offsets for other program headers after the device dumps are added.

In commit bbc4e7d273 ("i40e: fix race condition with PTP_TX_IN_PROGRESS

clear the progress bit as soon as possible.
A later commit 0bc0706b46 ("i40e: check for Tx timestamp timeouts during
watchdog") introduced similar code for detecting and handling cleanup of
a blocked Tx timestamp. This code did not use the same pattern for cleaning
up the skb.
Update this code to wait to free the skb until after the bit lock is
free, by first setting the ptp_tx_skb to NULL and clearing the lock.

The pfc related priority stats are already handled separately as these
stats are actually arrays of length I40E_MAX_USER_PRIORITY. Thus,
including them within i40e_gstrings_stats will just duplicate data.
Worse, the sizeof will be incorrect, as it will be the total size of the
stat arrays, which in this case is 8 * sizeof(u64), so we will only copy
the stat contents as if they were a u32.
Since we already correctly handle these stats else where, remove them
from the i40e_gstrings_stats.

One fix for an actual regression, the change to the SYSCALL_DEFINE wrapper broke
FTRACE_SYSCALLS for us due to a name mismatch. There's also another commit to
the same code to make sure we match all our syscalls with various prefixes.
And then just one minor build fix, and the removal of an unused variable that
was removed and then snuck back in due to some rebasing.
Thanks to:
Naveen N. Rao.

Currently the truncated bit is set only when 1) the mirrored packet
is larger than mtu and 2) the ipv4 packet tot_len is larger than
the actual skb->len. This patch adds another case for detecting
whether ipv6 packet is truncated or not, by checking the ipv6 header
payload_len and the skb->len.

Calling the variable l3edev was relevant when neighbor lookup was the
last stage in the simulated pipeline. Now that mlxsw handles bridges and
vlan devices as well, calling it "L3" is a misnomer.
Thus in mlxsw_sp_span_dmac(), rename to "dev", because that function is
just a service routine where the distinction between tunnel and egress
device isn't necessary.
In mlxsw_sp_span_entry_tunnel_parms_common(), rename to "edev" to
emphasize that the routine traces packet egress.

Emil adds a check for unsupported module during the reset routine for
ixgbe.
Luc Van Oostenryck fixes ixgbevf_xmit_frame() where it was not using the
correct return value (int).
Colin Ian King fixes a potential resource leak in ixgbe, where we were
not freeing ipsec in our cleanup path.

rxrpc: Fixes
Here are three fixes for AF_RXRPC and two tracepoints that were useful for
finding them:
(1) Fix missing start of expect-Rx-by timeout on initial packet
transmission so that calls will time out if the peer doesn't respond.
(2) Fix error reception on AF_INET6 sockets by using the correct family of
sockopts on the UDP transport socket.
(3) Fix setting the minimum security level on kernel calls so that they
can be encrypted.
(4) Add a tracepoint to log ICMP/ICMP6 and other error reports from the
transport socket.
(5) Add a tracepoint to log UDP sendmsg failure so that we can find out if
transmission failure occurred on the UDP socket.
