wifi: brcmfmac: Fix potential buffer overflow in brcmf_fweh_event_worker()

2022-11-10T17:17:40+00:00

commit 6788ba8aed4e28e90f72d68a9d794e34eac17295 upstream.

This patch fixes an intra-object buffer overflow in brcmfmac that occurs
when the device provides a 'bsscfgidx' equal to or greater than the
buffer size. The patch adds a check that leads to a safe failure if that
is the case.

This fixes CVE-2022-3628.

drm/i915/sdvo: Setup DDC fully before output init

2022-11-10T17:17:40+00:00

commit e79762512120f11c51317570519a1553c70805d8 upstream.

Call intel_sdvo_select_ddc_bus() before initializing any
of the outputs. And before that is functional (assuming no VBT)
we have to set up the controlled_outputs thing. Otherwise DDC
won't be functional during the output init but LVDS really
needs it for the fixed mode setup.

Note that the whole multi output support still looks very
bogus, and more work will be needed to make it correct.
But for now this should at least fix the LVDS EDID fixed mode
setup.

drm/i915/sdvo: Filter out invalid outputs more sensibly

2022-11-10T17:17:40+00:00

commit 3e206b6aa6df7eed4297577e0cf8403169b800a2 upstream.

We try to filter out the corresponding xxx1 output
if the xxx0 output is not present. But the way that is
being done is pretty awkward. Make it less so.

drm/rockchip: dsi: Force synchronous probe

2022-11-10T17:17:39+00:00

commit 81e592f86f7afdb76d655e7fbd7803d7b8f985d8 upstream.

We can't safely probe a dual-DSI display asynchronously
(driver_async_probe='*' or driver_async_probe='dw-mipi-dsi-rockchip'
cmdline), because dw_mipi_dsi_rockchip_find_second() pokes one DSI
device's drvdata from the other device without any locking.

Request synchronous probe, at least until this driver learns some
appropriate locking for dual-DSI initialization.

drm/rockchip: dsi: Clean up 'usage_mode' when failing to attach

2022-11-10T17:17:39+00:00

commit 0be67e0556e469c57100ffe3c90df90abc796f3b upstream.

If we fail to attach the first time (especially: EPROBE_DEFER), we fail
to clean up 'usage_mode', and thus will fail to attach on any subsequent
attempts, with "dsi controller already in use".

Re-set to DW_DSI_USAGE_IDLE on attach failure.

This is especially common to hit when enabling asynchronous probe on a
duel-DSI system (such as RK3399 Gru/Scarlet), such that we're more
likely to fail dw_mipi_dsi_rockchip_find_second() the first time.
