* | | License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman2017-11-02
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

I used the following coccinelle hack to make this transformation, except for the function headers and comment updates. The first and second rules are split because I couldn't find a way to remove the unused temporary variables at the same time I removed the parameter. // <smpl> @r@ expression A,B,D,E; identifier C; @@ ( - drm_fb_helper_init(A,B,C,D) + drm_fb_helper_init(A,B,D) | - drm_fbdev_cma_init_with_funcs(A,B,C,D,E) + drm_fbdev_cma_init_with_funcs(A,B,D,E) | - drm_fbdev_cma_init(A,B,C,D) + drm_fbdev_cma_init(A,B,D) ) @@ expression A,B,C,D,E; @@ ( - drm_fb_helper_init(A,B,C,D) + drm_fb_helper_init(A,B,D) | - drm_fbdev_cma_init_with_funcs(A,B,C,D,E) + drm_fbdev_cma_init_with_funcs(A,B,D,E) | - drm_fbdev_cma_init(A,B,C,D) + drm_fbdev_cma_init(A,B,D) ) @@ identifier r.C; type T; expression V; @@ - T C; <... when != C - C = V; ...> // </smpl> Changes since v1: - Rebased on top of the tip of drm-misc-next. - Remove mention to sti since a proper fix got merged.

| * | drm: Deduplicate driver initialization messageGabriel Krisman Bertazi2016-12-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several DRM drivers print the same initialization message right after drm_dev_register, so move that to common code. The exception is i915, which uses its own register handle, so let it keep its own message. Notice that this was tested only with Exynos, but looks simple enough for the other drivers.

The more annoying part with no pull request for 4 weeks is managing cross-tree work. The -intel pull request I'll follow up with does conflict quite a bit with -misc here. Longer-term (if drm-misc keeps growing) a drm-next-queued to accept pull request for the next merge window during this time might be useful. I'd also like to backmerge -rc2+this into drm-intel next week, we have quite a pile of patches waiting for the stuff in here. * tag 'drm-misc-next-2016-12-30' of git://anongit.freedesktop.org/git/drm-misc: (126 commits) drm: Add kerneldoc markup for new @scan parameters in drm_mm drm/mm: Document locking rules drm: Use drm_mm_insert_node_in_range_generic() for everyone drm: Apply range restriction after color adjustment when allocation drm: Wrap drm_mm_node.hole_follows drm: Apply tight eviction scanning to color_adjust drm: Simplify drm_mm scan-list manipulation drm: Optimise power-of-two alignments in drm_mm_scan_add_block() drm: Compute tight evictions for drm_mm_scan drm: Fix application of color vs range restriction when scanning drm_mm drm: Unconditionally do the range check in drm_mm_scan_add_block() drm: Rename prev_node to hole in drm_mm_scan_add_block() drm: Fix O= out-of-tree builds for selftests drm: Extract struct drm_mm_scan from struct drm_mm drm: Add asserts to catch overflow in drm_mm_init() and drm_mm_init_scan() drm: Simplify drm_mm_clean() drm: Detect overflow in drm_mm_reserve_node() drm: Fix kerneldoc for drm_mm_scan_remove_block() drm: Promote drm_mm alignment to u64 drm: kselftest for drm_mm and restricted color eviction ...

| | | | | | | | | | | | | | | | | | | | | | Prepare to mark sensitive kernel structures for randomization by making sure they're using designated initializers. These were identified during allyesconfig builds of x86, arm, and arm64, with most initializer fixes extracted from grsecurity.

| * drm: Don't include <drm/drm_encoder.h> in <drm/drm_crtc.h>Laurent Pinchart2016-12-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | <drm/drm_crtc.h> used to define most of the in-kernel KMS API. It has now been split into separate files for each object type, but still includes most other KMS headers to avoid breaking driver compilation. As a step towards fixing that problem, remove the inclusion of <drm/drm_encoder.h> from <drm/drm_crtc.h> and include it instead where appropriate. Also remove the forward declarations of the drm_encoder and drm_encoder_helper_funcs structures from <drm/drm_crtc.h> as they're not needed in the header. <drm/drm_encoder.h> now has to include <drm/drm_mode.h> and contain a forward declaration of struct drm_encoder in order to allow including it as the first header in a compilation unit.

Less duplicated information is a good thing. Note that I didn't put parens around the cpp*8 in the below cocci script, on account of not wanting spurious parens all over the place. Instead I did the unsafe way, and tried to look over the entire diff to spot if any dangerous expressions were produced. I didn't see any. There are some cases where previously the code did X*bpp/8, so the division happened after the multiplication. Those are now just X*cpp so the division effectively happens before the multiplication, but that is perfectly fine since bpp is always a multiple of 8. @@ struct drm_framebuffer *FB; expression E; @@ drm_helper_mode_fill_fb_struct(...) { ... - FB->bits_per_pixel = E; ... } @@ struct drm_framebuffer *FB; expression E; @@ i9xx_get_initial_plane_config(...) { ... - FB->bits_per_pixel = E; ... } @@ struct drm_framebuffer *FB; expression E; @@ ironlake_get_initial_plane_config(...) { ... - FB->bits_per_pixel = E; ... } @@ struct drm_framebuffer *FB; expression E; @@ skylake_get_initial_plane_config(...) { ... - FB->bits_per_pixel = E; ... } @@ struct drm_framebuffer FB; expression E; @@ ( - E * FB.bits_per_pixel / 8 + E * FB.format->cpp[0] | - FB.bits_per_pixel / 8 + FB.format->cpp[0] | - E * FB.bits_per_pixel >> 3 + E * FB.format->cpp[0] | - FB.bits_per_pixel >> 3 + FB.format->cpp[0] | - (FB.bits_per_pixel + 7) / 8 + FB.format->cpp[0] | - FB.bits_per_pixel + FB.format->cpp[0] * 8 | - FB.format->cpp[0] * 8 != 8 + FB.format->cpp[0] != 1 ) @@ struct drm_framebuffer *FB; expression E; @@ ( - E * FB->bits_per_pixel / 8 + E * FB->format->cpp[0] | - FB->bits_per_pixel / 8 + FB->format->cpp[0] | - E * FB->bits_per_pixel >> 3 + E * FB->format->cpp[0] | - FB->bits_per_pixel >> 3 + FB->format->cpp[0] | - (FB->bits_per_pixel + 7) / 8 + FB->format->cpp[0] | - FB->bits_per_pixel + FB->format->cpp[0] * 8 | - FB->format->cpp[0] * 8 != 8 + FB->format->cpp[0] != 1 ) @@ struct drm_plane_state *state; expression E; @@ ( - E * state->fb->bits_per_pixel / 8 + E * state->fb->format->cpp[0] | - state->fb->bits_per_pixel / 8 + state->fb->format->cpp[0] | - E * state->fb->bits_per_pixel >> 3 + E * state->fb->format->cpp[0] | - state->fb->bits_per_pixel >> 3 + state->fb->format->cpp[0] | - (state->fb->bits_per_pixel + 7) / 8 + state->fb->format->cpp[0] | - state->fb->bits_per_pixel + state->fb->format->cpp[0] * 8 | - state->fb->format->cpp[0] * 8 != 8 + state->fb->format->cpp[0] != 1 ) @@ @@ - (8 * 8) + 8 * 8 @@ struct drm_framebuffer FB; @@ - (FB.format->cpp[0]) + FB.format->cpp[0] @@ struct drm_framebuffer *FB; @@ - (FB->format->cpp[0]) + FB->format->cpp[0] @@ @@ struct drm_framebuffer { ... - int bits_per_pixel; ... }; v2: Clean up the 'cpp*8 != 8' and '(8 * 8)' cases (Laurent) v3: Adjusted the semantic patch a bit and regenerated due to code changes Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> (v1) Link: http://patchwork.freedesktop.org/patch/msgid/1481751140-18352-1-git-send-email-ville.syrjala@linux.intel.com
