tools/hv: Check for read/write errors

2012-10-07T15:32:25Z

commit 436473bc2173499ae274d0f50111d1e355006caf upstream. hv_kvp_daemon currently does not check whether fread() or fwrite() succeed. Add the necessary checks. Also, remove the incorrect use of feof() before fread(). Signed-off-by: Ben Hutchings Signed-off-by: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman

tools/hv: Fix exit() error code

2012-10-07T15:32:25Z

commit 6bb22fea25624ab593eee376fa5fb82d1b13f45a upstream. Linux native exit codes are 8-bit unsigned values. exit(-1) results in an exit code of 255, which is usually reserved for shells reporting 'command not found'. Use the portable value EXIT_FAILURE. (Not that this matters much for a daemon.) Signed-off-by: Ben Hutchings Signed-off-by: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman

tools/hv: Fix file handle leak

2012-10-07T15:32:25Z

commit d5ab482799e7c4c4b7c0aa67e8710dce28115d03 upstream. Match up each fopen() with an fclose(). Signed-off-by: Ben Hutchings Signed-off-by: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman

Tools: hv: verify origin of netlink connector message

2012-07-16T16:03:19Z

commit bcc2c9c3fff859e0eb019fe6fec26f9b8eba795c upstream. The SuSE security team suggested to use recvfrom instead of recv to be certain that the connector message is originated from kernel.

kbuild: install kernel-page-flags.h

2012-06-09T15:36:11Z

commit 9295b7a07c859a42346221b5839be0ae612333b0 upstream. Programs using /proc/kpageflags need to know about the various flags. The provides them and the comments in the file indicate that it is supposed to be used by user-level code. But the file is not installed. Install the headers and mark the unstable flags as out-of-bounds. The page-type tool is also adjusted to not duplicate the definitions Signed-off-by: Ulrich Drepper Acked-by: KOSAKI Motohiro Acked-by: Fengguang Wu Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds Signed-off-by: Greg Kroah-Hartman

USB: ffs-test: fix length argument of out function call

2012-06-01T07:18:21Z

commit eb9c5836384cd2a276254df6254ed71117983626 upstream. The out functions should only handle actual available data instead of the complete buffer. Otherwise for example the ep0_consume function will report ghost events since it tries to decode the complete buffer - which may contain partly invalid data.

perf stat: handle ENXIO error for perf_event_open

2012-05-09T17:14:41Z

perf stat on PPC currently fails to run: $ perf stat -- sleep 1 Error: open_counter returned with 6 (No such device or address). /bin/dmesg may provide additional information. Fatal: Not all events could be opened. The problem is that until 2.6.37 (behavior changed with commit b0a873e) perf on PPC returns ENXIO when hw_perf_event_init() fails. With this patch we get the expected behavior: $ perf stat -v -- sleep 1 cycles event is not supported by the kernel. stalled-cycles-frontend event is not supported by the kernel. stalled-cycles-backend event is not supported by the kernel. instructions event is not supported by the kernel. branches event is not supported by the kernel. branch-misses event is not supported by the kernel. ...

perf: Turn off compiler warnings for flex and bison generated files

2012-05-07T08:03:01Z

We don't know what types of warnings different versions of flex and bison combined with different versions of gcc is going to generate, so just punt and don't warn about anything. This fixes the build of perf for me on an openSUSE 12.1 system.
