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

2014-07-02T10:05:51Z

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

2014-06-20T15:34:09Z

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. Fixes: 3edce1cf813a ("USB: cdc-wdm: implement IOCTL_WDM_MAX_COMMAND") Cc: Bjørn Mork Signed-off-by: Jiri Slaby

usb: cdc-wdm: export cdc-wdm uapi header

2014-06-20T15:34:08Z

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

2014-06-06T10:38:17Z

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.

xattr: guard against simultaneous glibc header inclusion

2014-05-15T07:55:38Z

commit ea1a8217b06b41b31a2b60b0b83f75c77ef9c873 upstream. If the glibc xattr.h header is included after the uapi header, compilation fails due to an enum re-using a #define from the uapi header. Protect against this by guarding the define and enum inclusions against each other. (See https://lists.debian.org/debian-glibc/2014/03/msg00029.html and https://sourceware.org/glibc/wiki/Synchronizing_Headers for more information.)

floppy: bail out in open() if drive is not responding to block0 read

2014-04-18T08:58:54Z

commit 7b7b68bba5ef23734c35ffb0d8d82079ed604d33 upstream. In case reading of block 0 during open() fails, it is not the right thing to let open() succeed. Fix this by introducing FD_OPEN_SHOULD_FAIL_BIT flag, and setting it in case the bio callback encounters an error while trying to read block 0. As a bonus, this works around certain broken userspace (blkid), which is not able to properly handle read()s returning IO errors. Hence be nice to those, and bail out during open() already; if block 0 is not readable, read()s are not going to provide any meaningful data anyway.

drm/radeon: expose render backend mask to the userspace

2014-01-09T20:25:11Z

commit 439a1cfffe2c1a06e5a6394ccd5d18a8e89b15d3 upstream. This will allow userspace to correctly program the PA_SC_RASTER_CONFIG register, so it can be considered a fix. Signed-off-by: Marek Olšák Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

ALSA: compress: Fix 64bit ABI incompatibility

2013-12-20T15:48:49Z

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.

pkt_sched: fq: fix pacing for small frames

2013-12-08T15:29:13Z

[ Upstream commit f52ed89971adbe79b6438c459814034707b8ab91 ] For performance reasons, sch_fq tried hard to not setup timers for every sent packet, using a quantum based heuristic : A delay is setup only if the flow exhausted its credit. Problem is that application limited flows can refill their credit for every queued packet, and they can evade pacing. This problem can also be triggered when TCP flows use small MSS values, as TSO auto sizing builds packets that are smaller than the default fq quantum (3028 bytes) This patch adds a 40 ms delay to guard flow credit refill.
