2017-11-17OMAPFB: prevent buffer underflow in omapfb_parse_vram_param()Dan Carpenter1-1/+1
We cap the upper bound of "fbnum" but we also need to check for negatives or make the type unsigned. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Cc: Tomi Valkeinen <tomi.valkeinen@ti.com> Signed-off-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com>
2017-11-17video: fbdev: sm501fb: fix potential null pointer dereference on fbiColin Ian King1-2/+4
The pointer fbi is dereferenced with par = fbi->par before there is a null check on fbi, hence there is a potential null pointer dereference on a null par. Fix this by moving the dereference after the null pointer check.

2017-11-13fbcon: Initialize ops->info earlyThierry Reding1-0/+1
During console takeover, which happens for all DRM/KMS setups using the fbdev helpers, fbcon_startup() is called before fbcon_init() and as a result con2fb_acquire_newinfo() will not be called (info->fbcon_par was set to non-NULL in fbcon_startup()) to assign ops->info. This causes the cursor_timer_handler() to unreference a NULL pointer. Avoid this by unconditionally assigning ops->info during fbcon_startup() so that it will be available early, but keep the additional assignment in con2fb_acquire_newinfo() to support console remapping at runtime.

In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly.

2017-11-09fbdev: controlfb: Add missing modes to fix out of bounds accessGeert Uytterhoeven1-0/+2
Dan's static analysis says: drivers/video/fbdev/controlfb.c:560 control_setup() error: buffer overflow 'control_mac_modes' 20 <= 21 Indeed, control_mac_modes[] has only 20 elements, while VMODE_MAX is 22, which may lead to an out of bounds read when parsing vmode commandline options. The bug was introduced in v2.4.5.6, when 2 new modes were added to macmodes.h, but control_mac_modes[] wasn't updated: https://kernel.opensuse.org/cgit/kernel/diff/include/video/macmodes.h?h=v2.5.2&id=29f279c764808560eaceb88fef36cbc35c529aad Augment control_mac_modes[] with the two new video modes to fix this.

Rewrite the exit path based on 'au1200fb_drv_remove()'. We can safely iterate for all already handled planes. Even if not completely initialized, the functions that are called will silently accept the 'fb_info' structure that is passed. As soon as we find a NULL in the '_au1200fb_infos' array, we know that we have released all what we needed to release. So we can 'break'.

2017-11-09video: fbdev: au1200fb: Fix a potential double freeChristophe JAILLET1-1/+0
If 'fb_alloc_cmap()' fails, 'fbi->pseudo_palette' is freed and an error code is returned by 'au1200fb_init_fbinfo()'. The only caller, 'au1200fb_drv_probe()' goes to an error handling path where resources allocated in 'fb_alloc_cmap()' are freed. This leads to a double free of 'fbi->pseudo_palette'. Fix it by letting the caller free all resources in case of failure in 'au1200fb_init_fbinfo()'.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core update from Greg KH: "Here is the "big" driver core update for 4.14-rc1. It's really not all that big, the largest thing here being some firmware tests to help ensure that that crazy api is working properly. There's also a new uevent for when a driver is bound or unbound from a device, fixing a hole in the driver model that's been there since the very beginning. Many thanks to Dmitry for being persistent and pointing out how wrong I was about this all along :) Patches for the new uevents are already in the systemd tree, if people want to play around with them. Otherwise just a number of other small api changes and updates here, nothing major.
