2022-08-17fbcon: Fix accelerated fbdev scrolling while logo is still shownHelge Deller1-4/+0
commit 3866cba87dcd0162fb41e9b3b653d0af68fad5ec upstream. There is no need to directly skip over to the SCROLL_REDRAW case while the logo is still shown. When using DRM, this change has no effect because the code will reach the SCROLL_REDRAW case immediately anyway. But if you run an accelerated fbdev driver and have FRAMEBUFFER_CONSOLE_LEGACY_ACCELERATION enabled, console scrolling is slowed down by factors so that it feels as if you use a 9600 baud terminal. So, drop those unnecessary checks and speed up fbdev console acceleration during bootup.

2022-08-17fbcon: Fix boundary checks for fbcon=vc:n1-n2 parametersHelge Deller1-3/+5
commit cad564ca557f8d3bb3b1fa965d9a2b3f6490ec69 upstream. The user may use the fbcon=vc:<n1>-<n2> option to tell fbcon to take over the given range (n1...n2) of consoles. The value for n1 and n2 needs to be a positive number and up to (MAX_NR_CONSOLES - 1). The given values were not fully checked against those boundaries yet. To fix the issue, convert first_fb_vc and last_fb_vc to unsigned integers and check them against the upper boundary, and make sure that first_fb_vc is smaller than last_fb_vc.

2022-07-07fbcon: Prevent that screen size is smaller than font sizeHelge Deller2-1/+31
We need to prevent that users configure a screen size which is smaller than the currently selected font size. Otherwise rendering chars on the screen will access memory outside the graphics memory region. This patch adds a new function fbcon_modechange_possible() which implements this check and which later may be extended with other checks if necessary. The new function is called from the FBIOPUT_VSCREENINFO ioctl handler in fbmem.c, which will return -EINVAL if userspace asked for a too small screen size.

2022-06-29fbdev: Disable sysfb device registration when removing conflicting FBsJavier Martinez Canillas1-0/+12
The platform devices registered by sysfb match with firmware-based DRM or fbdev drivers, that are used to have early graphics using a framebuffer provided by the system firmware. DRM or fbdev drivers later are probed and remove conflicting framebuffers, leading to these platform devices for generic drivers to be unregistered. But the current solution has a race, since the sysfb_init() function could be called after a DRM or fbdev driver is probed and request to unregister the devices for drivers with conflicting framebuffes. To prevent this, disable any future sysfb platform device registration by calling sysfb_disable(), if a driver requests to remove the conflicting framebuffers.

2022-05-28video: fbdev: vesafb: Fix a use-after-free due early fb_info cleanupJavier Martinez Canillas1-2/+3
Commit b3c9a924aab6 ("fbdev: vesafb: Cleanup fb_info in .fb_destroy rather than .remove") fixed a use-after-free error due the vesafb driver freeing the fb_info in the .remove handler instead of doing it in .fb_destroy. This can happen if the .fb_destroy callback is executed after the .remove callback, since the former tries to access a pointer freed by the latter. But that change didn't take into account that another possible scenario is that .fb_destroy is called before the .remove callback. For example, if no process has the fbdev chardev opened by the time the driver is removed. If that's the case, fb_info will be freed when unregister_framebuffer() is called, making the fb_info pointer accessed in vesafb_remove() after that to no longer be valid. To prevent that, move the expression containing the info->par to happen before the unregister_framebuffer() function call.

git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARMv4T/v5 multiplatform support from Arnd Bergmann: "This series has been 12 years in the making, it mostly finishes the work that was started with the founding of Linaro to clean up platform support in the kernel. The largest change here is a cleanup of the omap1 platform, which is the final ARM machine type to get converted to the common-clk subsystem. All the omap1 specific drivers are now made independent of the mach/*.h headers to allow the platform to be part of a generic ARMv4/v5 multiplatform kernel. The last bit that enables this support is still missing here while we wait for some last dependencies to make it into the mainline kernel through other subsystems. The s3c24xx, ixp4xx, iop32x, ep93xx and dove platforms were all almost at the point of allowing multiplatform kernels, this work gets completed here along with a few additional cleanup. At the same time, the s3c24xx and s3c64xx are now deprecated and expected to get removed in the future. The PXA and OMAP1 bits are in a separate branch because of dependencies. Once both branches are merged, only the three Intel StrongARM platforms (RiscPC, Footbridge/NetWinder and StrongARM1100) need separate kernels, and there are no plans to include these" * tag 'arm-multiplatform-5.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (61 commits) ARM: ixp4xx: Consolidate Kconfig fixing issue ARM: versatile: Add missing of_node_put in dcscb_init ARM: config: Refresh IXP4xx config after multiplatform ARM: omap1: add back omap_set_dma_priority() stub ARM: omap: fix missing declaration warnings ARM: omap: fix address space warnings from sparse ARM: spear: remove include/mach/ subdirectory ARM: davinci: remove include/mach/ subdirectory ARM: omap2: remove include/mach/ subdirectory integrator: remove empty ap_init_early() ARM: s3c: fix include path MAINTAINERS: omap1: Add Janusz as an additional maintainer ARM: omap1: htc_herald: fix typos in comments ARM: OMAP1: fix typos in comments ARM: OMAP1: clock: Remove noop code ARM: OMAP1: clock: Remove unused code ARM: OMAP1: clock: Fix UART rate reporting algorithm ARM: OMAP1: clock: Fix early UART rate issues ARM: OMAP1: Prepare for conversion of OMAP1 clocks to CCF ARM: omap1: fix build with no SoC selected ...
