linux/const.h: Add _BITUL() and _BITULL()

2016-06-07T08:42:44Z

commit 2fc016c5bd8aad2e201cdf71b9fb4573f94775bd upstream. Add macros for single bit definitions of a specific type. These are similar to the BIT() macro that already exists, but with a few exceptions: 1. The namespace is such that they can be used in uapi definitions. 2. The type is set with the _AC() macro to allow it to be used in assembly. 3. The type is explicitly specified to be UL or ULL. Signed-off-by: H.

USB: usbfs: allow URBs to be reaped after disconnection

2015-08-03T16:29:47Z

commit 3f2cee73b650921b2e214bf487b2061a1c266504 upstream. The usbfs API has a peculiar hole: Users are not allowed to reap their URBs after the device has been disconnected. There doesn't seem to be any good reason for this; it is an ad-hoc inconsistency. The patch allows users to issue the USBDEVFS_REAPURB and USBDEVFS_REAPURBNDELAY ioctls (together with their 32-bit counterparts on 64-bit systems) even after the device is gone. If no URBs are pending for a disconnected device then the ioctls will return -ENODEV rather than -EAGAIN, because obviously no new URBs will ever be able to complete. The patch also adds a new capability flag for USBDEVFS_GET_CAPABILITIES to indicate that the reap-after-disconnect feature is supported.

netfilter: xt_bpf: add mising opaque struct sk_filter definition

2014-11-21T17:22:54Z

commit e10038a8ec06ac819b7552bb67aaa6d2d6f850c1 upstream. This structure is not exposed to userspace, so fix this by defining struct sk_filter; so we skip the casting in kernelspace. This is safe since userspace has no way to lurk with that internal pointer.

ALSA: compress: Cancel the optimization of compiler and fix the size of struct for all platform.

2014-06-26T19:12:41Z

commit 2bd0ae464a6cf7363bbf72c8545e0aa43caa57f0 upstream. Cancel the optimization of compiler for struct snd_compr_avail which size will be 0x1c in 32bit kernel while 0x20 in 64bit kernel under the optimizer. That will make compaction between 32bit and 64bit. So add packed to fix the size of struct snd_compr_avail to 0x1c for all platform.

USB: cdc-wdm: properly include types.h

2014-06-11T19:03:25Z

commit 7ac3764fcafc06e72e1a79a9d998b9fdd900b2a6 upstream. The file include/uapi/linux/usb/cdc-wdm.h uses a __u16 so it needs to include types.h as well to make the build system happy.

commit 7d1896360f4d055d68565ef8ed56a677580f1a39 upstream. The include/uapi/linux/usb/cdc-wdm.h header defines cdc-wdm userspace APIs and should be exported by make headers_install.

drm/tegra: Remove gratuitous pad field

2014-06-07T20:25:32Z

commit cbfbbabb89b37f6bad05f478d906a385149f288d upstream. The version of the drm_tegra_submit structure that was merged all the way back in 3.10 contains a pad field that was originally intended to properly pad the following __u64 field. Unfortunately it seems like a different field was dropped during review that caused this padding to become unnecessary, but the pad field wasn't removed at that time. One possible side-effect of this is that since the __u64 following the pad is now no longer properly aligned, the compiler may (or may not) introduce padding itself, which results in no predictable ABI. Rectify this by removing the pad field so that all fields are again naturally aligned. Technically this is breaking existing userspace ABI, but given that there aren't any (released) userspace drivers that make use of this yet, the fallout should be minimal.

ALSA: compress: Fix 64bit ABI incompatibility

2013-12-20T15:45:06Z

commit 6733cf572a9e20db2b7580a5dd39d5782d571eec upstream. snd_pcm_uframes_t is defined as unsigned long so it would take different sizes depending on 32 or 64bit architectures. As we don't want this ABI incompatibility, and there is no real 64bit user yet, let's make it the fixed size with __u32. Also bump the protocol version number to 0.1.2.

perf: Fix perf ring buffer memory ordering

2013-11-20T20:27:47Z

commit bf378d341e4873ed928dc3c636252e6895a21f50 upstream. The PPC64 people noticed a missing memory barrier and crufty old comments in the perf ring buffer code. So update all the comments and add the missing barrier. When the architecture implements local_t using atomic_long_t there will be double barriers issued; but short of introducing more conditional barrier primitives this is the best we can do.

drm: Pad drm_mode_get_connector to 64-bit boundary

2013-11-13T03:05:34Z

commit bc5bd37ce48c66e9192ad2e7231e9678880f6f8e upstream. Pavel Roskin reported that DRM_IOCTL_MODE_GETCONNECTOR was overwritting the 4 bytes beyond the end of its structure with a 32-bit userspace running on a 64-bit kernel. This is due to the padding gcc inserts as the drm_mode_get_connector struct includes a u64 and its size is not a natural multiple of u64s. 64-bit kernel: sizeof(drm_mode_get_connector)=80, alignof=8 sizeof(drm_mode_get_encoder)=20, alignof=4 sizeof(drm_mode_modeinfo)=68, alignof=4 32-bit userspace: sizeof(drm_mode_get_connector)=76, alignof=4 sizeof(drm_mode_get_encoder)=20, alignof=4 sizeof(drm_mode_modeinfo)=68, alignof=4 Fortuituously we can insert explicit padding to the tail of our structures without breaking ABI.
