[Linux-stable-mirror] [PATCH 1/3] backlight: as3711_bl: fix device-tree node lookup

by Johan Hovold

Fix child-node lookup during probe, which ended up searching the whole device tree depth-first starting at the parent rather than just matching on its children. To make things worse, the parent mfd node was also prematurely freed. Note that the nodes returned from the two calls to of_parse_phandle() are also leaking, but fixing that is a bit more involved as pointers to node fields are being stored for later use.

[Linux-stable-mirror] [PATCH] drm/i915: Fix init_clock_gating for resume

by Ville Syrjala

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> Moving the init_clock_gating() call from intel_modeset_init_hw() to intel_modeset_gem_init() had an unintended effect of not applying some workarounds on resume. This, for example, cause some kind of corruption to appear at the top of my IVB Thinkpad X1 Carbon LVDS screen after hibernation. Fix the problem by explicitly calling init_clock_gating() from the resume path. I really hope this doesn't break something else again...

[Linux-stable-mirror] [PATCH] fanotify: fix -EOVERFLOW with large files on 64-bit

by Stefan Nuernberger

From: Will Woods <wwoods(a)redhat.com> commit 1e2ee49f7f1b79f0b14884fe6a602f0411b39552 upstream. On 64-bit systems, O_LARGEFILE is automatically added to flags inside the open() syscall (also openat(), blkdev_open(), etc). Userspace therefore defines O_LARGEFILE to be 0 - you can use it, but it's a no-op. Everything should be O_LARGEFILE by default. But: when fanotify does create_fd() it uses dentry_open(), which skips all that. And userspace can't set O_LARGEFILE in fanotify_init() because it's defined to 0. So if fanotify gets an event regarding a large file, the read() will just fail with -EOVERFLOW. This patch adds O_LARGEFILE to fanotify_init()'s event_f_flags on 64-bit systems, using the same test as open()/openat()/etc. Addresses https://bugzilla.redhat.com/show_bug.cgi?id=696821 Signed-off-by: Will Woods <wwoods(a)redhat.com> Acked-by: Eric Paris <eparis(a)redhat.com> Reviewed-by: Jan Kara <jack(a)suse.cz> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds(a)linux-foundation.org> [snu: Backported to 3.2 / 3.10: adjusted context] Signed-off-by: Stefan Nuernberger <snu(a)amazon.com> Reviewed-by: Pawel Wieczorkiewicz <wipawel(a)amazon.de> Reviewed-by: Simon Veith <sveith(a)amazon.de> Cc: <stable(a)vger.kernel.org> # 3.2.x and 3.10.x --- fs/notify/fanotify/fanotify_user.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/fs/notify/fanotify/fanotify_user.c b/fs/notify/fanotify/fanotify_user.c index d57995e1cfd7..dd3d9d13a4c4 100644 --- a/fs/notify/fanotify/fanotify_user.c +++ b/fs/notify/fanotify/fanotify_user.c @@ -712,6 +712,9 @@ SYSCALL_DEFINE2(fanotify_init, unsigned int, flags, unsigned int, event_f_flags) group->fanotify_data.user = user; atomic_inc(&user->fanotify_listeners); + if (force_o_largefile()) + event_f_flags |= O_LARGEFILE; + group->fanotify_data.f_flags = event_f_flags; #ifdef CONFIG_FANOTIFY_ACCESS_PERMISSIONS mutex_init(&group->fanotify_data.access_mutex); -- 2.15.0

The x and y hints receives from the host are unsigned 32 bit integers and they get set to -1 (0xffffffff) when invalid. Before this commit the vboxvideo driver was storing them in an u16 causing the -1 to be truncated to 65535 which, once reported to userspace, was breaking gnome 3.26+ in Wayland mode. This commit stores the host values in 32 bit variables, removing the truncation and checks for -1, replacing it with 0 as -1 is not a valid suggested-offset-property value. Likewise the properties are now initialized to 0 instead of -1, since -1 is not a valid value. This fixes gnome 3.26+ in Wayland mode not working with the vboxvideo driver.
