2020-07-31crypto: ccp - use generic power managementVaibhav Gupta
Drivers using legacy power management .suspen()/.resume() callbacks have to manage PCI states and device's PM states themselves. They also need to take care of standard configuration registers. Switch to generic power management framework using a single "struct dev_pm_ops" variable to take the unnecessary load from the driver. This also avoids the need for the driver to directly call most of the PCI helper functions and device power state control functions as through the generic framework, PCI Core takes care of the necessary operations, and drivers are required to do only device-specific jobs.

2020-07-31drm/nouveau: Accept 'legacy' format modifiersJames Jones
Accept the DRM_FORMAT_MOD_NVIDIA_16BX2_BLOCK() family of modifiers to handle broken userspace Xorg modesetting and Mesa drivers. Existing Mesa drivers are still aware of only these older format modifiers which do not differentiate between different variations of the block linear layout. When the format modifier support flag was flipped in the nouveau kernel driver, the X.org modesetting driver began attempting to use its format modifier-enabled framebuffer path. Because the set of format modifiers advertised by the kernel prior to this change do not intersect with the set of format modifiers advertised by Mesa, allocating GBM buffers using format modifiers fails and the modesetting driver falls back to non-modifier allocation. However, it still later queries the modifier of the GBM buffer when creating its DRM-KMS framebuffer object, receives the old-format modifier from Mesa, and attempts to create a framebuffer with it. Since the kernel is still not aware of these formats, this fails. Userspace should not be attempting to query format modifiers of GBM buffers allocated with a non- format-modifier-aware allocation path, but to avoid breaking existing userspace behavior, this change accepts the old-style format modifiers when creating framebuffers and applying them to planes by translating them to the equivalent new-style modifier. To accomplish this, some layout parameters must be assumed to match properties of the device targeted by the relevant ioctls. To avoid perpetuating misuse of the old-style modifiers, this change does not advertise support for them. Doing so would imply compatibility between devices with incompatible memory layouts. Tested with Xorg 1.20 modesetting driver, weston@c46c70dac84a4b3030cd05b380f9f410536690fc, gnome & KDE wayland desktops from Ubuntu 18.04, and sway 1.5 Reported-by: Kirill A.

2020-07-30net/mlx5e: fix bpf_prog reference count leaks in mlx5e_alloc_rqXin Xiong
The function invokes bpf_prog_inc(), which increases the reference count of a bpf_prog object "rq->xdp_prog" if the object isn't NULL. The refcount leak issues take place in two error handling paths. When either mlx5_wq_ll_create() or mlx5_wq_cyc_create() fails, the function simply returns the error code and forgets to drop the reference count increased earlier, causing a reference count leak of "rq->xdp_prog". Fix this issue by jumping to the error handling path err_rq_wq_destroy while either function fails.

2020-07-30net/mlx5e: E-Switch, Add misc bit when misc fields changed for mirroringJianbo Liu
The modified flow_context fields in FTE must be indicated in modify_enable bitmask. Previously, the misc bit in modify_enable is always set as source vport must be set for each rule. So, when parsing vxlan/gre/geneve/qinq rules, this bit is not set because those are all from the same misc fileds that source vport fields are located at, and we don't need to set the indicator twice. After adding per vport tables for mirroring, misc bit is not set, then firmware syndrome happens. To fix it, set the bit wherever misc fileds are changed. This also makes it unnecessary to check misc fields and set the misc bit accordingly in metadata matching, so here remove it. Besides, flow_source must be specified for uplink because firmware will check it and some actions are only allowed for packets received from uplink.

2020-07-30mlxsw: spectrum_cnt: Use flex_array_size() helper in memcpy()Gustavo A. R. Silva
Make use of the flex_array_size() helper to calculate the size of a flexible array member within an enclosing structure. This helper offers defense-in-depth against potential integer overflows, while at the same time makes it explicitly clear that we are dealing witha flexible array member. Also, remove unnecessary pointer identifier sub_pool. Signed-off-by: Gustavo A. R.

2020-07-30atm: fix atm_dev refcnt leaks in atmtcp_remove_persistentXin Xiong
atmtcp_remove_persistent() invokes atm_dev_lookup(), which returns a reference of atm_dev with increased refcount or NULL if fails. The refcount leaks issues occur in two error handling paths. If dev_data->persist is zero or PRIV(dev)->vcc isn't NULL, the function returns 0 without decreasing the refcount kept by a local variable, resulting in refcount leaks. Fix the issue by adding atm_dev_put() before returning 0 both when dev_data->persist is zero or PRIV(dev)->vcc isn't NULL.
