+Subject: drm/atomic-helper: reset vblank on crtc reset
+
+From: Daniel Vetter <daniel.vetter@ffwll.ch>
+
+[ Upstream commit 51f644b40b4b794b28b982fdd5d0dd8ee63f9272 ]
+
+Only when vblanks are supported ofc.
+
+Some drivers do this already, but most unfortunately missed it. This
+opens up bugs after driver load, before the crtc is enabled for the
+first time. syzbot spotted this when loading vkms as a secondary
+output. Given how many drivers are buggy it's best to solve this once
+and for all in shared helper code.
+
+Aside from moving the few existing calls to drm_crtc_vblank_reset into
+helpers (i915 doesn't use helpers, so keeps its own) I think the
+regression risk is minimal: atomic helpers already rely on drivers
+calling drm_crtc_vblank_on/off correctly in their hooks when they
+support vblanks. And driver that's failing to handle vblanks after
+this is missing those calls already, and vblanks could only work by
+accident when enabling a CRTC for the first time right after boot.
+
+Big thanks to Tetsuo for helping track down what's going wrong here.
+
+There's only a few drivers which already had the necessary call and
+needed some updating:
+- komeda, atmel and tidss also needed to be changed to call
+ __drm_atomic_helper_crtc_reset() intead of open coding it
+- tegra and msm even had it in the same place already, just code
+ motion, and malidp already uses __drm_atomic_helper_crtc_reset().
+- Laurent noticed that rcar-du and omap open-code their crtc reset and
+ hence would actually be broken by this patch now. So fix them up by
+ reusing the helpers, which brings the drm_crtc_vblank_reset() back.
+
+Only call left is in i915, which doesn't use drm_mode_config_reset,
+but has its own fastboot infrastructure. So that's the only case where
+we actually want this in the driver still.
+
+I've also reviewed all other drivers which set up vblank support with
+drm_vblank_init. After the previous patch fixing mxsfb all atomic
+drivers do call drm_crtc_vblank_on/off as they should, the remaining
+drivers are either legacy kms or legacy dri1 drivers, so not affected
+by this change to atomic helpers.
+
+v2: Use the drm_dev_has_vblank() helper.
+
+v3: Laurent pointed out that omap and rcar-du used drm_crtc_vblank_off
+instead of drm_crtc_vblank_reset. Adjust them too.
+
+v4: Laurent noticed that rcar-du and omap open-code their crtc reset
+and hence would actually be broken by this patch now. So fix them up
+by reusing the helpers, which brings the drm_crtc_vblank_reset() back.
+
+v5: also mention rcar-du and ompadrm in the proper commit message
+above (Laurent).

+Subject: fbmem: pull fbcon_update_vcs() out of fb_set_var()
+
+From: Tetsuo Handa <penguin-kernel@i-love.sakura.ne.jp>
+
+[ Upstream commit d88ca7e1a27eb2df056bbf37ddef62e1c73d37ea ]
+
+syzbot is reporting OOB read bug in vc_do_resize() [1] caused by memcpy()
+based on outdated old_{rows,row_size} values, for resize_screen() can
+recurse into vc_do_resize() which changes vc->vc_{cols,rows} that outdates
+old_{rows,row_size} values which were saved before calling resize_screen().
+
+Daniel Vetter explained that resize_screen() should not recurse into
+fbcon_update_vcs() path due to FBINFO_MISC_USEREVENT being still set
+when calling resize_screen().
+
+Instead of masking FBINFO_MISC_USEREVENT before calling fbcon_update_vcs(),
+we can remove FBINFO_MISC_USEREVENT by calling fbcon_update_vcs() only if
+fb_set_var() returned 0. This change assumes that it is harmless to call
+fbcon_update_vcs() when fb_set_var() returned 0 without reaching
+fb_notifier_call_chain().
