* drm: Update todo.rstDaniel Vetter2018-09-091-58/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - drmP.h is now fully split up. - vkms is happening (and will gain its own todo and docs under a new vkms.rst file real soon) - legacy cruft is completely hidden now, drm_vblank.c is split out from drm_irq.c now. I've decided to drop the task to split out drm_legacy.ko, partially because Dave already rejected a patch to hide the old dri1 drivers better. Current state feels good enough to me. - best_encoder atomic cleanup is done (it's now the default, not even exported anymore) - bunch of smaller things v2: - Explain why the drm_legacy.ko task is dropped (Emil). - typos (Sam). v3: Fix typo (Ilia) Reviewed-by: Emil Velikov <emil.velikov@collabora.com> Reviewed-by: Heiko Stuebner <heiko@sntech.de> Cc: Ilia Mirkin <imirkin@alum.mit.edu> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Emil Velikov <emil.l.velikov@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Gustavo Padovan <gustavo@padovan.org> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Sean Paul <seanpaul@chromium.org> Cc: David Airlie <airlied@linux.ie> Link: https://patchwork.freedesktop.org/patch/msgid/20180905181509.19530-1-daniel.vetter@ffwll.ch

| | | | | | | | | | | | | | | | Remove the kerneldoc and EXPORT_SYMBOL which aren't used and really shouldn't ever be used by drivers directly. Unfortunately this means we need to move the set_writeback_fb function around to avoid a forward decl.

* dt-bindings: display: atmel: optional video-interface of endpointsPeter Rosin2018-08-271-0/+23
| | | | | | | | | | | | | | | | | | | | | With bus-type/bus-width properties in the endpoint nodes, the video- interface of the connection can be specified for cases where the heuristic fails to select the correct output mode. This can happen e.g. if not all RGB pins are routed on the PCB; the driver has no way of knowing this, and needs to be told explicitly. This is critical for the devices that have the "conflicting output formats" issue (SAM9N12, SAM9X5, SAMA5D3), since the most significant RGB bits move around depending on the selected output mode. For devices that do not have the "conflicting output formats" issue (SAMA5D2, SAMA5D4), this is completely irrelevant.

[Test Code] config A bool "a" config B bool "b" imply A depends on A In the code above, Kconfig cannot calculate the symbol values correctly due to the circular dependency. For example, allyesconfig followed by syncconfig results in an odd behavior because CONFIG_B becomes visible in syncconfig. $ make allyesconfig scripts/kconfig/conf --allyesconfig Kconfig # # configuration written to .config # $ cat .config # # Automatically generated file; DO NOT EDIT. # Main menu # CONFIG_A=y $ make syncconfig scripts/kconfig/conf --syncconfig Kconfig * * Restart config... * * * Main menu * a (A) [Y/n/?] y b (B) [N/y/?] (NEW) To detect this correctly, sym_check_expr_deps() should recurse to not only sym->rev_dep.expr but also sym->implied.expr . At this moment, sym_check_print_recursive() cannot distinguish 'select' and 'imply' since it does not know the precise context where the recursive dependency has been hit. This will be solved by the next commit. In fact, even the document and the unit-test are confused. Using 'imply' does not solve recursive dependency since 'imply' addresses the unmet direct dependency, which 'select' could cause.

These resets must be kept de-asserted until the device is enabled. This is specified as shared because some SoCs like UniPhier series have common reset controls with all ahci controller instances. However, according to Thierry's view, https://www.spinics.net/lists/linux-ide/msg55357.html some hardware-specific drivers already use their own resets, and the common reset make a path to occur double controls of resets. The ahci_platform_get_resources() can get and control the reset only when the second argument includes AHCI_PLATFORM_GET_RESETS bit.

The latter is invoked by ata_pio_sector(), atapi_send_cdb() and __atapi_pio_bytes() which in turn is invoked by ata_sff_hsm_move(). The latter function requires that the "ap->lock" lock is held which needs to be taken with disabled interrupts. There is no need have to have ata_sff_data_xfer_noirq() which invokes ata_sff_data_xfer32() with disabled interrupts because at this point the interrupts are already disabled. Remove the function and its references to it and replace all callers with ata_sff_data_xfer32().

The purpose is to make data spoofing attacks harder. This protection can be turned on and off separately for FIFOs and regular files via sysctl, just like the symlinks/hardlinks protection. This patch is based on Openwall's "HARDEN_FIFO" feature by Solar Designer. This is a brief list of old vulnerabilities that could have been prevented by this feature, some of them even allow for privilege escalation: CVE-2000-1134 CVE-2007-3852 CVE-2008-0525 CVE-2009-0416 CVE-2011-4834 CVE-2015-1838 CVE-2015-7442 CVE-2016-7489 This list is not meant to be complete. It's difficult to track down all vulnerabilities of this kind because they were often reported without any mention of this particular attack vector. In fact, before hardlinks/symlinks restrictions, fifos/regular files weren't the favorite vehicle to exploit them.
