[PATCH AUTOSEL 5.4 01/14] drm/nouveau/nouveau_bo: fix potential memory leak in nouveau_bo_alloc()
From: Jianglei Nie niejianglei2021@163.com
[ Upstream commit 6dc548745d5b5102e3c53dc5097296ac270b6c69 ]
nouveau_bo_alloc() allocates a memory chunk for "nvbo" with kzalloc(). When some error occurs, "nvbo" should be released. But when WARN_ON(pi < 0)) equals true, the function return ERR_PTR without releasing the "nvbo", which will lead to a memory leak.
We should release the "nvbo" with kfree() if WARN_ON(pi < 0)) equals true.

[ Upstream commit 94dc3471d1b2b58b3728558d0e3f264e9ce6ff59 ]
The strlen() function returns a size_t which is an unsigned int on 32-bit arches and an unsigned long on 64-bit arches. But in the drm_copy_field() function, the strlen() return value is assigned to an 'int len' variable.
Later, the len variable is passed as copy_from_user() third argument that is an unsigned long parameter as well.
In theory, this can lead to an integer overflow via type conversion. Since the assignment happens to a signed int lvalue instead of a size_t lvalue.
In practice though, that's unlikely since the values copied are set by DRM drivers and not controlled by userspace. But using a size_t for len is the correct thing to do anyways.

There are some struct drm_driver fields that are required by drivers since drm_copy_field() attempts to copy them to user-space via DRM_IOCTL_VERSION.
But it can be possible that a driver has a bug and did not set some of the fields, which leads to drm_copy_field() attempting to copy a NULL pointer:

The definition of MIN_I64 in bw_fixed.c can cause gcc to whinge about integer overflow, because it is treated as a positive value, which is then negated. The temporary positive value is not necessarily representable.
This causes the following warning: ../drivers/gpu/drm/amd/amdgpu/../display/dc/dml/calcs/bw_fixed.c:30:19: warning: integer overflow in expression ‘-9223372036854775808’ of type ‘long long int’ results in ‘-9223372036854775808’ [-Woverflow] 30 | (int64_t)(-(1LL << 63)) | ^
Writing out (-MAX_I64 - 1) works instead.

When registering a connector, the kernel sends a hotplug uevent in drm_connector_register(). When unregistering a connector, drivers are expected to send a uevent as well. However, user-space has no way to figure out that the connector isn't registered anymore: it'll still be reported in GETCONNECTOR IOCTLs.
The documentation for DRM_CONNECTOR_UNREGISTERED states:
The connector […] has since been unregistered and removed from userspace, or the connector was unregistered before it had a chance to be exposed to userspace

This commit fixes vertical timings of the VEC (composite output) modes to accurately represent the 525-line ("NTSC") and 625-line ("PAL") ITU-R standards.
Previous timings were actually defined as 502 and 601 lines, resulting in non-standard 62.69 Hz and 52 Hz signals being generated, respectively.

Some Toshibas have a broken acpi-video interface for brightness control and need a special firmware call on resume to turn the panel back on. So far these have been using the disable_backlight_sysfs_if workaround to deal with this.
The recent x86/acpi backlight refactoring has broken this workaround: 1. This workaround relies on acpi_video_get_backlight_type() returning acpi_video so that the acpi_video code actually runs; and 2. this relies on the actual native GPU driver to offer the sysfs backlight interface to userspace.
After the refactor this breaks since the native driver will no longer register its backlight-device if acpi_video_get_backlight_type() does not return native and making it return native breaks 1.
Keeping the acpi_video backlight handling on resume active, while not using it to set the brightness, is necessary because it does a _BCM call on resume which is necessary to turn the panel back on on resume.
Looking at the DSDT shows that this _BCM call results in a Toshiba HCI_SET HCI_LCD_BRIGHTNESS call, which turns the panel back on.
This kind of special vendor specific handling really belongs in the vendor specific acpi driver. An earlier patch in this series modifies toshiba_acpi to make the necessary HCI_SET call on resume on affected models.
With toshiba_acpi taking care of the HCI_SET call on resume, the acpi_video code no longer needs to call _BCM on resume.
So instead of using the (now broken) disable_backlight_sysfs_if workaround, simply setting acpi_backlight=native to disable the broken apci-video interface is sufficient fix things now.
After this there are no more users of the disable_backlight_sysfs_if flag and as discussed above the flag also no longer works as intended, so remove the disable_backlight_sysfs_if flag entirely.

This patch goes hand in hand with:
commit 3cb1f40dfdc3 ("drivers/platform: toshiba_acpi: Call HCI_PANEL_POWER_ON on resume on some models")
and without that commit also being present it will cause a regression on the quirked Toshiba models.
This really is part of the big x86/ACPI backlight handling refactor which has landed in 6.1 and as such is not intended for older kernels, please drop this from the stable series.

Hans

[ Upstream commit 2a2565272a3628e45d61625e36ef17af7af4e3de ]
On a MSI S270 with Fedora 37 x86_64 / systemd-251.4 the module does not properly autoload.
This is likely caused by issues with how systemd-udevd handles the single quote char (') which is part of the sys_vendor / chassis_vendor strings on this laptop. As a workaround remove the single quote char + everything behind it from the sys_vendor + chassis_vendor matches. This fixes the module not autoloading.

[ Upstream commit 1261255531088208daeca818e2b486030b5339e5 ]
The field mode_valid in exynos_drm_crtc_ops is expected to be of type enum drm_mode_status (*mode_valid)(struct exynos_drm_crtc *crtc, const struct drm_display_mode *mode);
Likewise for mode_valid in drm_connector_helper_funcs.
The mismatched return type breaks forward edge kCFI since the underlying function definition does not match the function hook definition.
The return type of mixer_mode_valid and hdmi_mode_valid should be changed from int to enum drm_mode_status.
