2021-10-19mailbox: mtk-cmdq: Fix local clock ID usageFei Shao1-5/+3
In the probe function, the clock IDs were pointed to local variables which should only be used in the same code block, and any access to them after the probing stage becomes an use-after-free case. Since there are only limited variants of the gce clock names so far, we can just declare them as static constants to fix the issue.

So the C flag bit is part of gpr context, that's why riscv totally remove the C bit in the ISA. That makes sr reg clear from userspace to supervisor privilege.

csky restore_sigcontext() blindly overwrites regs->sr with the value it finds in sigcontext. Attacker can store whatever they want in there, which includes things like S-bit. Userland shouldn't be able to set that, or anything other than C flag (bit 0). Do the same thing other architectures with protected bits in flags register do - preserve everything that shouldn't be settable in user mode, picking the rest from the value saved is sigcontext.

2021-10-15drm/nouveau/fifo: Reinstate the correct engine bit programmingMarek Vasut1-1/+1
Commit 64f7c698bea9 ("drm/nouveau/fifo: add engine_id hook") replaced fifo/chang84.c g84_fifo_chan_engine() call with an indirect call of fifo/g84.c g84_fifo_engine_id(). The G84_FIFO_ENGN_* values returned from the later g84_fifo_engine_id() are incremented by 1 compared to the previous g84_fifo_chan_engine() return values. This is fine either way for most of the code, except this one line where an engine bit programmed into the hardware is derived from the return value. Decrement the return value accordingly, otherwise the wrong engine bit is programmed into the hardware and that leads to the following failure: nouveau 0000:01:00.0: gr: 00000030 [ILLEGAL_MTHD ILLEGAL_CLASS] ch 1 [003fbce000 DRM] subc 3 class 0000 mthd 085c data 00000420 On the following hardware: lspci -s 01:00.0 01:00.0 VGA compatible controller: NVIDIA Corporation GT216GLM [Quadro FX 880M] (rev a2) lspci -ns 01:00.0 01:00.0 0300: 10de:0a3c (rev a2) Fixes: 64f7c698bea9 ("drm/nouveau/fifo: add engine_id hook") Signed-off-by: Marek Vasut <marex@denx.de> Cc: <stable@vger.kernel.org> # 5.12+ Cc: Ben Skeggs <bskeggs@redhat.com> Cc: Karol Herbst <kherbst@redhat.com> Cc: Lyude Paul <lyude@redhat.com> Reviewed-by: Karol Herbst <kherbst@redhat.com> Reviewed-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Karol Herbst <kherbst@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211007214117.231472-1-marex@denx.de Signed-off-by: Dave Airlie <airlied@redhat.com>
2021-10-15drm/hyperv: Fix double mouse pointersDexuan Cui3-1/+55
Hyper-V supports a hardware cursor feature. It is not used by Linux VM, but the Hyper-V host still draws a point as an extra mouse pointer, which is unwanted, especially when Xorg is running. The hyperv_fb driver uses synthvid_send_ptr() to hide the unwanted pointer. When the hyperv_drm driver was developed, the function synthvid_send_ptr() was not copied from the hyperv_fb driver. Fix the issue by adding the function into hyperv_drm.
