2019-06-29bpf: fix uapi bpf_prog_info fields alignmentBaruch Siach1-0/+1
Merge commit 1c8c5a9d38f60 ("Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next") undid the fix from commit 36f9814a494 ("bpf: fix uapi hole for 32 bit compat applications") by taking the gpl_compatible 1-bit field definition from commit b85fab0e67b162 ("bpf: Add gpl_compatible flag to struct bpf_prog_info") as is. That breaks architectures with 16-bit alignment like m68k. Add 31-bit pad after gpl_compatible to restore alignment of following fields. Thanks to Dmitry V. Levin his analysis of this bug history.

Other than verifying pidfd based polling, the tests make sure that wait semantics are preserved with the pidfd poll. Notably the 2 cases: 1. If a thread group leader exits while threads still there, then no pidfd poll notifcation should happen. 2. If a non-thread group leader does an execve, then the thread group leader is signaled to exit and is replaced with the execing thread as the new leader, however the parent is not notified in this case.

Add a comment explaining why this is probably okay and display the value in the test case. While at it, explain why the behavior is correct with respect to PKRU. Modify also the selftest to print the odd error code so that there is a way to demonstrate the odd behaviour. If anyone really cares about more accurate emulation, the behaviour could be changed.

2019-06-27iio: iio-utils: Fix possible incorrect mask calculationBastien Nocera1-2/+2
On some machines, iio-sensor-proxy was returning all 0's for IIO sensor values. It turns out that the bits_used for this sensor is 32, which makes the mask calculation: *mask = (1 << 32) - 1; If the compiler interprets the 1 literals as 32-bit ints, it generates undefined behavior depending on compiler version and optimization level. On my system, it optimizes out the shift, so the mask value becomes *mask = (1) - 1; With a mask value of 0, iio-sensor-proxy will always return 0 for every axis. Avoid incorrect 0 values caused by compiler optimization. See original fix by Brett Dutro <[email protected]> in iio-sensor-proxy: https://github.com/hadess/iio-sensor-proxy/commit/9615ceac7c134d838660e209726cd86aa2064fd3 Signed-off-by: Bastien Nocera <[email protected]> Signed-off-by: Jonathan Cameron <[email protected]>

2019-06-25tools perf: Move from sane_ctype.h obtained from git to the Linux's originalArnaldo Carvalho de Melo46-117/+155
We got the sane_ctype.h headers from git and kept using it so far, but since that code originally came from the kernel sources to the git sources, perhaps its better to just use the one in the kernel, so that we can leverage tools/perf/check_headers.sh to be notified when our copy gets out of sync, i.e. when fixes or goodies are added to the code we've copied. This will help with things like tools/lib/string.c where we want to have more things in common with the kernel, such as strim(), skip_spaces(), etc so as to go on removing the things that we have in tools/perf/util/ and instead using the code in the kernel, indirectly and removing things like EXPORT_SYMBOL(), etc, getting notified when fixes and improvements are made to the original code. Hopefully this also should help with reducing the difference of code hosted in tools/ to the one in the kernel proper.

2019-06-25tc-testing: Restore original behaviour for namespaces in tdcLucas Bates8-20/+296
This patch restores the original behaviour for tdc prior to the introduction of the plugin system, where the network namespace functionality was split from the main script. It introduces the concept of required plugins for testcases, and will automatically load any plugin that isn't already enabled when said plugin is required by even one testcase. Additionally, the -n option for the nsPlugin is deprecated so the default action is to make use of the namespaces. Instead, we introduce -N to not use them, but still create the veth pair. buildebpfPlugin's -B option is also deprecated. If a test cases requires the features of a specific plugin in order to pass, it should instead include a new key/value pair describing plugin interactions: "plugins": { "requires": "buildebpfPlugin" }, A test case can have more than one required plugin: a list can be inserted as the value for 'requires'.
