xattr: fix check for simultaneous glibc header inclusion

2014-10-13T12:25:34Z

commit bfcfd44cce2774f19daeb59fb4e43fc9aa80e7b8 upstream. The guard was introduced in commit ea1a8217b06b ("xattr: guard against simultaneous glibc header inclusion") but it is using #ifdef to check for a define that is either set to 1 or 0. Fix it to use #if instead. * Without this patch: $ { echo "#include "; echo "#include "; } | gcc -E -Iinclude/uapi - >/dev/null include/uapi/linux/xattr.h:19:0: warning: "XATTR_CREATE" redefined [enabled by default] #define XATTR_CREATE 0x1 /* set value, fail if attr already exists */ ^ /usr/include/x86_64-linux-gnu/sys/xattr.h:32:0: note: this is the location of the previous definition #define XATTR_CREATE XATTR_CREATE ^ * With this patch: $ { echo "#include "; echo "#include "; } | gcc -E -Iinclude/uapi - >/dev/null (no warnings) Signed-off-by: Filipe Brandenburger Acked-by: Serge E.

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

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.

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.

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.

perf: Fix perf ring buffer memory ordering

2013-10-29T11:01:19Z

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.
