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.

addition of mptdebug.h
This patch adds a new file mptdebug.h in the fusion source directory,
which contains different debug macros. The existing debug macros and
flags are removed from the mptbase.h and Makefile In Kconfig a new
configuration parameter FUSION_LOGGING is added to enable/disable the
logging support during compile time.

* Wide port support added - using James Bottomley's new SAS wide port API.
(There is a known problem in sas transport layer reported yesterday to
James. The Kobject dev.bus_ids for end devices are not unique across
expanders. I have added a work around in this patch, where I asigning
an unique port identifier for every port within the host - this solves
the problem, but I expect a fix from James in the sas transport).
* Adding target_alloc and target_destroy entry points, and moving code over
from the slave entry points.
* The renaming of some mptscsih_xxx functions declared in mptsas.c,
to mptsas_xxx.
* Target Reset moved from slave_destroy to hotplug work thread
handling (with regard to device removal). Also inhibit IO to end device
while device is being broken down . Talked to James Smart about this
at Linux Expo (with questions of how the fc transport handles this).
* Cleaning up the kzalloc's, and kfree's

From: "Moore, Eric Dean" <Emoore@lsil.com>
Changelog for mpt version 3.01.03:
(1) Fix fifo memory allocation under 64bit systems
by merging 3 seperate memory allocations into one call.
Before this fix, it was possible that these seperate
pci_alloc_consistent() calls were crossing the 4GB
hardware boundary.
Delete the MPTBASE_MEM_ALLOC_FIFO_FIX logic.
Backout recent ak@muc.de workaround.
(2) Replace wrappers for CHIPREG_XXX with defines;
per request from Jeff Garzik [jgarzik@pobox.com]
(3) Remove support for FC909.
(4) Remove PortIo modules parameter.
(5) Move procmpt_destroy function before pci_unregister_driver,
as the memory allocated for the proc was not being deallocated.
(6) Remove mptscshi_reset_timeouts function. The timer was
already expired when mod_timer is called.
(7) Fix small bug in slave_destroy, which could prevent domain
validation on hidden drive in a RAID volume.
----------------------------------------------------------------------
Changelog for mpt version 3.01.02:
(1) Andi Kleen[ak@suse.de]
put warning "Device (0:0:0) reported QUEUE_FULL!" into debug messages
(2) Alexander Stohr[Alexander.Stohr@gmx.de]
fix warnings from mptscsih_setup when driver isn't compiled as module
(3) Randy.Dunlap[rddunlap@osdl.org]
Remove unnecessary min/max macros and change calls to
use kernel.h macros instead.

One of the goals of the whole new modversions implementation:
export-objs is gone for good!
|
|
Makefiles no longer need to include Rules.make, which is currently an
empty file. This patch removes it from the drivers tree Makefiles.
|
|
Instead of using make -C <subdir>, just use make -f <subdir>/Makefile.
This means we now call gcc/ld/... always from the topdir.
Advantages are:
o We don't need to use -I$(TOPDIR)/include and the like, just
-Iinclude works.
o __FILE__ gives the correct relative path from the topdir instead
of an absolute path, as it did before for included headers
o gcc errors/warnings give the correct relative path from the topdir
o takes us a step closer to a non-recursive build (though that's probably
as close as it gets)
The changes to Rules.make were done in a way which only uses the new way
for the standard recursive build (which remains recursive, just without
cd), all the archs do make -C arch/$(ARCH)/boot ..., which should keep
working as before. However, of course this should be converted eventually,
it's possible to do so piecemeal arch by arch.
It seems to work fine for most of the standard kernel. Potential places
which need changing are added -I flags to the command line, which now
need to have the path relative to the topdir and explicit rules for
generating files, which need to properly use $(obj) / $(src) to work
correctly.
|
|
O_TARGET should basically be dead for non arch-specific code in 2.5
(it's still functional, though), so kill the cases where it creeped back
in.

This updates the Fusion-MPT driver to the latest stable version.
Changes affect the driver source only.
Major Changes:
Reworked the calls save_flags, cli, restore_flags to 2.5 format.
Modified DV invocation and to handle illegal bus configuration
Negotiation settings honor NVRAM
Bug Fix: Pushing F/W onto part during driver unload.
Bug Fix: Force F/W reset for 1030 on driver load.
Bug Fix: F/W download algorithm.
Bug Fix: Found a memory leak in mptctl.c
Bug Fix: Forcing data direction for reads and writes (sg issue)
Bug Fix: Wrong mask in Inquiry data ANSI version
Minor Changes:
Modified the debug and logging statements of the driver
Upgraded the MPI include files (lsi/)
|
|
This patch cleans up most of the Makefile's to list the correct files
(i.e. the ones which do have "EXPORT_SYMBOL" in them) in $(export-objs)
Contributed by "Lightweight patch manager"

|
Some archs sneaked additional flags for ld into $(LD). This can be done
cleaner now, by just using $(LDFLAGS).
|
|
Use the new
obj-$(CONFIG_FOO) += foo/
syntax to descend into a subdir and link in the result, if
CONFIG_FOO=y.
