License cleanup: add SPDX GPL-2.0 license identifier to files with no license
Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

sunvnet: add stats to track ldom to ldom packets and bytes
In this driver, there is a "port" created for the connection to each of the other ldoms; a netdev queue is mapped to each port, and they are collected under a single netdev. The generic netdev statistics show us all the traffic in and out of our network device, but don't show individual queue/port stats. This patch breaks out the traffic counts for the individual ports and gives us a little view into the state of those connections.

ldmvsw: better use of link up and down on ldom vswitch
When an ldom VM is bound, the network vswitch infrastructure is set up for it, but was being forced 'UP' by the userland switch configuration script. When 'UP' but not actually connected to a running VM, the ipv6 neighbor probes fail (not a horrible thing) and start cluttering up the kernel logs. Funny thing: these are debug messages that never actually show up, but we do see the net_ratelimited messages that say N callbacks were suppressed. This patch defers the netif_carrier_on() until an actual link has been established with the VM, as indicated by receiving an LDC_EVENT_UP from the underlying LDC protocol. Similarly, we take the link down when we see the LDC_EVENT_RESET. Now when we see the ndo_open(), we reset the link to get things talking again.

ldmvsw: Make sunvnet_common compatible with ldmvsw
Modify sunvnet common code and data structures to be compatible
with both sunvnet and ldmvsw drivers.
Details:
Sunvnet operates on "vnet-port" nodes which appear in the Machine
Description (MD) in a guest domain. Ldmvsw operates on "vsw-port"
nodes which appear in the MD of a service domain.
A difference between the sunvnet driver and the ldmvsw driver is
the sunvnet driver creates a network interface (i.e. a struct net_device)
for every vnet-port *parent* "network" node. Several vnet-ports may appear
under this common parent network node - each corresponding to a common parent
network interface. Conversely, since bridge/vswitch software will need
to interface with every vsw-port in a system, the ldmvsw driver creates
a network interface (i.e. a struct net_device) for every vsw-port - not
every parent node as with sunvnet. This difference required some special
handling in the common code as explained below.
There are 2 key data structures used by the sunvnet and ldmvsw drivers
(which are now found in sunvnet_common.h):
1. struct vnet_port
This structure represents a vnet-port node in sunvnet and a vsw-port
in the ldmvsw driver.
2. struct vnet
This structure represents a parent "network" node in sunvnet and a parent
"virtual-network-switch" node in ldmvsw.
Since the sunvnet driver allocates a net_device for every parent "network"
node, a net_device member appears in the struct vnet. Since the ldmvsw
driver allocates a net_device for every port, a net_device member was
added to the vnet_port. The common code distinguishes which structure
net_device member to use by checking a 'vsw' bit that was added to the
vnet_port structure. See the VNET_PORT_TO_NET_DEVICE() marco in
sunvnet_common.h.
The netdev_priv() in sunvnet is allocated as a vnet. The netdev_priv()
in ldmvsw is a vnet_port. Therefore, any place in the common code
where a netdev_priv() call was made, a wrapper function was implemented
in each driver to first get the vnet and/or vnet_port (in a driver
specific way) and pass them as newly added parameters to the common
functions (see wrapper funcs: vnet_set_rx_mode() and vnet_poll_controller()).
Since these wrapper functions call __tx_port_find(), __tx_port_find() was
moved from the common code back into sunvnet.c. Note - ldmvsw.c does not
require this function.
These changes also required that port_is_up() be made
into a common function and thus it was given a _common suffix and
exported like the other common functions.
A wrapper function was also added for vnet_start_xmit_common() to pass a
driver-specific function arg to return the port associated with a given
struct sk_buff and struct net_device. This was required because
vnet_start_xmit_common() grabs a lock prior to getting the associated
port. Using a function pointer arg allowed the code to work unchanged
without risking changes to the non-trivial locking logic in
vnet_start_xmit_common().

ldmvsw: Split sunvnet driver into common code
Split sunvnet.c into sunvnet.c and sunvnet_common.c. Details: Since the sunvnet and ldmvsw drivers will both use common sunvnet code, move the functions (and support functions) anticipated to be common code from sunvnet.c to sunvnet_common.c. Similarly, sunvnet.h was renamed to sunvnet_common.h. The sunvnet_common.c code will be compiled into the kernel and act as a library of functions that are linked by either (or both) drivers when loaded. Function names for external functions in sunvnet_common.c (to be called by both the sunvnet and ldmvsw drivers) were tagged with a "_common" suffix to clearly designate them as common functions. No functional changes as of yet... just moved code verbatim to the new sunvnet_common.c/h files. Makefile/Kconfig support added to build sunvnet_common.c file. The code is included in the kernel if SUN_LDOMS is defined/selected. NOTE - per the SubmittingPatches documentation, since the code was just moved from one file another, the code was NOT checkpatch'd in this commit to aid in review.
