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.

perf stat: Fix case where guest/host monitoring is not supported by kernel

2012-05-01T17:20:00Z

By default, perf stat sets exclude_guest = 1. But when you run perf on a kernel which does not support host/guest filtering, then you get an error saying the event in unsupported. This comes from the fact that when the perf_event_attr struct passed by the user is larger than the one known to the kernel there is safety check which ensures that all unknown bits are zero. But here, exclude_guest is 1 (part of the unknown bits) and thus the perf_event_open() syscall return EINVAL. To my surprise, running perf record on the same kernel did not exhibit the problem. The reason is that perf record handles the problem by catching the error and retrying with guest/host excludes set to zero. For some reason, this was not done with perf stat. This patch fixes this problem.

perf build-id: Fix filename size calculation

2012-05-01T17:13:00Z

The filename is a pointer variable so the sizeof(filename) will return length of a pointer. Fix it by using 'size'.

ktest: Fix reboot on success stopping all reboots

2012-05-01T12:25:48Z

The change to let individual tests decide to reboot the machine on success of the entire test also prevented errors from rebooting when an error was detected. The "no_reboot" variable was only cleared if the test had reboot_on_success set. But the no_reboot variable also prevents the test rebooting when an error was detected even when REBOOT_ON_ERROR was set. Add a new "reboot_success" variable that is used to determine if the test should reboot on success and not touch the no_reboot variable. Signed-off-by: Steven Rostedt
